Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This disclosure is a continuation-in-part of U.S. Ser. No. 15/297,041, filed Oct. 18, 2016, which is hereby incorporated by reference in its entirety. 
    
    
     FIELD OF THE DISCLOSURE 
     This disclosure relates to apparatus for extinguishing a wick flame of a candle disposed in a candle container and related methods. 
     BACKGROUND 
     Candles are aesthetic accessories that may be used in homes and other places as a decoration to provide a special ambiance and soft glow. However, unlike other decorations, lit candles may present a flame and fire hazard to their environment. The dangers from lit candles may be eliminated with their extinguishment. Candles may include different types and associated aesthetics. A jar candle may be a type of candle which includes a wax candle housed in a glass jar. 
     SUMMARY 
     Current solutions for automatically extinguishing lit candles may include digital timers and electronic sensors coupled with actuators configured to cause a shutter or a lid to dose. Such devices may be susceptible to electronic failures and may require period maintenance (e.g., changing batteries, replacing worn out electronic components). Furthermore, conventional candle extinguishers may include a timing device that may be either AC or battery powered. As such, the candle-timer may be either permanently tethered to a wall socket or may run the risk of having the batteries drain. For example, drained batteries and/or a power outage from a breaker overload and/or from a storm (in the case of the candle-timer being powered by AC electricity) may result in safety features of the candle-timer to cease operation. Other solutions may include devices that spray non-flammable fluid to extinguish the candle. Accordingly, one or more aspects of the present disclosure relate to controlling how long a wick-based candle can remain lit thereby increasing convenience and safety. 
     One aspect of the disclosure relates to an apparatus configured for extinguishing a wick flame of a candle disposed in a candle container. The apparatus may include a base configured to be positioned adjacent to an opening of the candle container that provides access to a wick and the flame of the candle. The apparatus may include a flexible, retractable lid connected to the base and configured to move between (a) an open position wherein the wick and flame are accessible via the opening and (b) a closed position wherein the lid encloses the opening of the candle container to thereby extinguish the wick flame. The retractable lid may include a first half and a second half. Control arms are positioned around the opening of the candle container and configured to keep the halves of the retractable lid in the open position. The one or more control arms may be configured to cause the retractable lid to close responsive to the one or more control arms being released. The halves include ends that are configured to move in a generally upward direction relative to the opening and towards each other to meet in the closed position. The apparatus may include a mechanical timer. The mechanical timer may be configured to control a countdown such that, responsive to an expiration of a predetermined time period, the control arms are caused to be released thereby causing the retractable lid to move from its open position to its closed position. The apparatus may include a manual over-ride configured to cause the control arms to be released independent of the mechanical timer. The apparatus may include a plurality of sensors provided on the base. The plurality of sensors may be spaced around the opening and configured to cause the retractable lid to move from its open position to its closed position responsive to a detection of impact or disturbance. 
     Another aspect of this disclosure relates to a method for extinguishing a wick flame of a candle disposed in a candle container using the apparatus described above. The method includes: setting the mechanical timer for a predetermined amount of time; providing the first half and the second half of the retractable lid in the open position; lighting a wick of the candle container to produce a wick flame; detecting, using at least one of the plurality of sensors, an impact to the candle container; and causing the control arms to move the first half and second half from the open position to the closed position. The movement of the first half and second half includes moving ends of the halves in a generally upward direction relative to the opening and towards each other to meet in the closed position. 
     These and other features, and characteristics of the present technology, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures.

     DETAILED DESCRIPTION 
       FIG. 1  illustrates a top view of an exemplary implementation of an apparatus  10  configured for extinguishing a wick flame of a candle disposed in a candle container  45  (e.g., jar candles, scented candles in jars), in accordance with one or more implementations. In some implementations, apparatus  10  may include a base  15 , a retractable lid  20 , one or more control arms  25   a ,  25   b ,  25   c , and  25   d , a mechanical timer  30 , a manual override  35 , and one or more sensors  40   a ,  40   b ,  40   c ,  40   d ,  40   e , and  40   f , and/or other components. The base  15  may be positioned adjacent to an opening  46  of the candle container  45  that provides access to a wick and flame of the candle therein. In some implementations, base  15  may be configured to be attached, connected, or coupled to the candle container. For example, the base  15  may be positioned such that it is around and surrounds the opening  46  of the candle container, in accordance with an embodiment. In another embodiment, the base  15  may be positioned adjacent to or on top of the opening  46 . In yet another embodiment, the base  15  is secured to the candle container  45  just below its opening  46  such that the retractable lid  20  is positioned around or adjacent to the opening  46 . 
     In some implementations, base  15  may include a retention device. In some implementations, the retention device may be sized to fit one or more different candle containers and/or to hold, lock, and/or fit base  15  to one or more different candle containers. For example, the retention device may be sized to fit different candle openings within a given range similar to a worm clamp, e.g., such that a portion is adjustable and locked around a device. Other examples of retention devices that may be used or adapted for use with the base  15  are hose clamps with bolts, e.g., T-bolts, and/or keyed hose clamps, for example, that may be manually adjusted in width or diameter and locked using the bolt or key. In one embodiment, such as shown by retention device  14  in  FIG. 6 , the retention device may be provided on part of the base  15  (e.g., a bottom part or ring). Such a depiction is exemplary only, and thus the type of retention device is not intended to be limiting. A retention device may be used with either or both illustrated embodiments. 
     In some implementations, one or more edges of the base may be beveled and/or chamfered. In some implementations, the base and/or its edges may be configured to, responsive to the candle container being knocked over, prevent the candle container from rolling. 
     In some implementations, apparatus  10  may include retractable lid  20  connected to the base  15 . The retractable lid  20  is configured to expand and enclose an opening  46  of the candle container  45  when the retractable lid is in a closed position (e.g., see  FIGS. 4 and 7 ), and collapse and open for positioning adjacent to or around the opening when the retractable lid is in an open position (e.g., see  FIGS. 3 and 6 ). In some implementations, retractable lid  20  may include a first half  20   a  and a second half  20   b . In accordance with an embodiment, the halves  20   a  and  20   b  include ends that are configured to move in an generally upward direction relative to the opening  46  (e.g., as shown by arrows A in  FIGS. 3 and 6 ) and towards each other to meet in the closed position. In some implementations, first half  20   a  and second half  20   b  may be configured to form a seal when first half  20   a  and second half  20   b  are in the closed position (e.g., as illustrated in  FIG. 4  and described below). In some implementations, first half  20   a  and second half  20   b  may form individual halves of a sem ispherical retractable lid. That is, when in the closed position, the halves  20   a ,  20   b  of the retractable lid  20  may form a dome or similar shape over the opening  46 , such as shown in  FIG. 4  or  FIG. 7 , for example. 
     In some implementations, first half  20   a  and second half  20   b  may be constructed from a fire-safe material. In some implementations, metals such as steel, brass, silver, alumina, and/or other metals may be used to construct the retractable lid. In some implementations, silicone and/or other non-flammable materials may be used to construct the retractable lid. In some implementations, retractable lid  20   a  and  20   b  may be constructed using one or more flexible materials such that first half  20   a  and second half  20   b  are stored on a first side and a second side of the candle container respectively. The first and second halves  20   a ,  20   b  may be configured to collapse accordion-style, e.g., such that portions are bent or folded and stacked on top of each other when collapsed and placed in an open position. 
     In some implementations, first half  20   a  and second half  20   b  may include a curved metal shaft (see, e.g., shaft  18  of  FIG. 7 ) positioned at an end of each half  20   a  and  20   b  such that when the halves  20   a ,  20   b  are closed towards each other, the curved metal shafts meet in the closed position of the retractable lid  20 . Each curved metal shaft may be of semi-circular configuration and positioned near, around, or on a side or lip of opening of the candle container  45  when the retractable lid  20  is in its open position, for example. In some implementations, the curved metal shaft may be compressed and retained under the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms when retractable lid  20   a  and  20   b  is locked in an open position. The shafts may be attached at or near the control arms  25   a ,  25   b ,  25   c , and  25   d . In some implementations, the curved metal shaft may be encased in a fire safe material. In some embodiments, the curved metal shafts may be embedded within fire safe material of the lid portions  20   a  and  20   b.    
     In some implementations, the fire safe material for the retractable lid  20  and/or its parts may include silicone, coated fiberglass, carbonized acrylic felt (PANOx), and/or other fire safe material capable of withstanding the heat from the open flame for several seconds without reaching their flashpoint temperature. The fire safe material used for the halves  20   a ,  20   b  may be configured to withstand temperatures up to 700 degrees Fahrenheit, in accordance with one embodiment. 
     By way of a non-limiting example,  FIG. 2  illustrates a side view of an exemplary implementation of an apparatus  10  configured for extinguishing a wick flame of a candle disposed in a candle container, in accordance with one or more implementations. As depicted in  FIG. 2 , first half  20   a  and second half  20   b  are stored on or adjacent to a first side and a second side of candle container  45  respectively. 
     In some implementations, retractable lid  20   a  and  20   b  may be spring loaded, e.g., via tension springs. For example, the lid may have tension springs provided on either side of first half  20   a  and second half  20   b  near the control arms  25   a - 25   b . When the lid  20  is opened, the retractable lid is spring loaded via tension being added to the tensions springs (e.g., through rotation of those springs) when the halves  20   a  and  20   b  of the retractable lid  20  are moved to the open position and kept open by the control arms  25   a - 25   d . This added/loaded spring tension assists the control arms  25   a - 25   d  in moving the first and second halves  20   a  and  20   b  to the closed position when they are released. In some implementations, responsive to the retractable lid  20   a  and  20   b  being in a closed position, the wick  50  flame may be deprived of oxygen such that the candle is extinguished. 
     In some implementations, first half  20   a  and second half  20   b  may be caused to close by the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms without disrupting stability of the entire apparatus, knocking the candle over, and/or creating a fire hazard. In some implementations, due to the use of flexible materials in constructing first half  20   a  and second half  20   b , the retractable lid halves may be stored on either side of the candle container without negatively affecting a center of gravity of apparatus  10 . As such first half  20   a  and second half  20   b  may be closed rapidly without causing an imbalance to the candle container. 
     In some implementations, the retractable lid may be configured such that while the candle remains lit, first half  20   a  and/or second half  20   b  do not restrict the airflow to and from the candle. Unrestricted air flow may allow scented candles to emit a fragrant odor for a given area. In some implementations, first half  20   a  and/or second half  20   b  may be configured to remain in the open position while the candle remains lit. First half  20   a  and second half  20   b  remaining in the open position while the candle is lit may prevent continual exposure to the heat source and may reduce degradation of the retractable lid due to the flame. 
     Returning to  FIG. 1 , apparatus  10  may include one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms. In some implementations, control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be configured to keep retractable lid  20   a  and  20   b  in an open position (e.g., as illustrated in  FIG. 3  and described below). Control arms are positioning around the opening  46  of the candle container  45 . In an embodiment, control arms may be provided on both sides of the candle container  45 , such as seen in  FIG. 1  and  FIG. 9 . In some implementations, control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be configured to cause retractable lid  20   a  and  20   b  to close responsive to one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms being released. In some implementations, one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be disposed to provide a connecting bridge between retractable lid  20   a  and  20   b  and the mechanical timer  30  (described below). In some implementations, one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be held in place for a period of time predetermined by setting mechanical timer  30  such that retractable lid is  20   a  and  20   b  kept open. In some implementations, one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be constructed of metal and mounted to base  15  (e.g., proximate to where first half  20   a  and second half  20   b  are joined). In some implementations, one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be configured such that one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms latch over respective one of first half  20   a  or second half  20   b ). In some implementations, responsive to expiration of a predetermined time period, activation of manual over-ride, and/or detection of an impact or disturbance, one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may release first half  20   a  and second half  20   b  such that a pressure provided by springs  36  causes first half  20   a  and second half  20   b  to close. 
     In one embodiment, control arms  25   a - 25   d  may include an arm portion that extends along at least a part of each lid half  20   a  and  20   b . For example, the curved metal shafts  18  (described later below) may be a part of the control arms. In an embodiment, the control arms may include a portion that extends from each point  25   a ,  25   b ,  25   c , and  25   d  along an edge of each half  20   a  and  20   b  of the lid  20 . Control arms  25   a - 25   d  may include pivot points or shafts and a lock/release mechanism associated therewith. In some embodiments, the tension springs  36  are associated with the control arms  25   a - 25   d  at its points or shafts. For example, each of the control arms may include an arm portion that may be shaped as one half of a half  20   a  or  20   b  of lid  20 , or a ¼ of a circle, or less, in accordance with an embodiment. The arm portion may be positioned along an edge of a lid portion. The arm portion of the control arms may further include a small projection shaft that is connected at one of the connection points  34  of the control arm  25   a ,  25   b ,  25   c ,  25   d  and receives a tension spring  36  thereon. Generally, however, it should be noted that the mechanisms for forming the control arms  25   a - 25   d  may vary so as long as it may be configured to secure the mechanical parts, e.g., lid portions  20   a  and  20   b , in a closed position and keep the lid in an open position (e.g., when the timer is activated) 
     By way of a non-limiting example,  FIG. 3  illustrates a front view of an exemplary implementation of an apparatus  10  configured for extinguishing a wick flame of a candle disposed in a candle container  45  in accordance with one or more implementations. As illustrated in  FIG. 3 , control arms  25   a ,  25   b , and  25   c ,  25   d  (not shown in  FIG. 3 ) may keep first half  20   a  and second half  20   b  of the retractable lid in an open position. 
     In one embodiment, control arms  25   a ,  25   b  are provided on a first side of the candle container and control arms  25   c ,  25   d  are provided on an opposite side of the container. In an embodiment, each of the control arms are configured to make the first and second halves  20   a ,  20   b  hinged or pivotable between the open position and the closed position. Each of the halves may include two pivoting points on opposite sides of the opening, for example. 
     Returning to  FIG. 1 , apparatus  10  may include a mechanical timer  30 . Mechanical timer  30  may be configured to control a countdown such that, responsive to an expiration of a predetermined time period, the one or more control arms are caused to be released, to then close the lid. In some implementations, mechanical timer  30  may be configured such that responsive to the predetermined time period being set on the mechanical timer  30 , retractable lid  20   a  and  20   b  is configured to open. That is, the activation of the timer  30  may be configured to allow the halves  20   a ,  20   b  to move from a (default) closed position to an open position. For example, the control arms  25   a - 25   d  may be configured to unlock and allow the lid halves  20   a ,  20   b  to pivot generally downwardly towards the opening  46  of the candle holder. As illustrated in  FIG. 3  and  FIG. 6 , for example, responsive to a predetermined time period being set on mechanical timer  30 , the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be configured to cause retractable lid  20   a  and  20   b  to remain in an open position, e.g., via a locking mechanism. In some implementations, responsive to the predetermined time period being set on mechanical timer  30 , the candle may be lit, e.g., after the halves  20   a  and  20   b  are provided (and maintained) in an open position. 
     The setting of the mechanical timer  30  may include rotating or turning a portion of the timer or its body. For example, as shown in  FIG. 3 , at least a knob (e.g., illustrated in the form of an arrow) may be turned or rotated to set a time period for the countdown. 
     The embodiment described with reference to  FIGS. 6-17  illustrates an alternate implementation of a mechanical timer  30  associated with base  15  of the apparatus  10 , in the form of timer ring  30 - 1 , in accordance with this disclosure. The timer ring  30 - 1  may be configured for rotation around the base  15  and/or container  45 , e.g., in a clockwise direction, to set a predetermined time period, in accordance with an embodiment herein. 
     Returning to  FIG. 1 , apparatus  10  may include a manual over-ride  35 . In some implementations, manual over-ride  35  may be configured to cause the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms to be released independent of mechanical timer  30 . In some implementations, responsive to manual over-ride  35  being triggered, the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be released. Responsive to the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms being released, the retractable lid  20   a  and  20   b  may be caused to close extinguishing the flame independent of mechanical timer  30 . As illustrated in  FIG. 3 , manual over-ride  35  may be disposed on a surface of the candle container such that it is accessible to a user. The manual over-ride  35  may be disposed above mechanical timer  30 , below mechanical timer  30 , proximate to a side of mechanical timer  30 , and/or any other position. 
     The embodiment described with reference to  FIGS. 6-17  illustrates an alternate implementation of a manual override  35  associated with base  15  of apparatus  10 , in accordance with this disclosure. For example, in accordance with an embodiment, the manual override  35  is provided in the form of a button on the base  15  and associated with timer ring  30 - 1  as well as control arms  25   a - 25   d.    
     Returning to  FIG. 1 , apparatus  10  may include one or more sensors  40   a  . . .  40   n  (n being a definite number). In accordance with an embodiment, multiple sensors are provided with apparatus  10 . In the exemplary illustrated embodiment, sensors  40   a ,  40   b ,  40   c ,  40   d ,  40   e ,  40   f  are shown. However, the illustrations are not intended to be limiting and fewer sensors may be provided with apparatus  10 . In some implementations, one or more sensors  40   a ,  40   b ,  40   c ,  40   d ,  40   e ,  40   f , and/or other sensors may be configured to cause one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms to be released responsive to a detection of impact. In some implementations, one or more sensors  40   a ,  40   b ,  40   c ,  40   d ,  40   e ,  40   f  may cause one or more control arms  25   a ,  25   b ,  25   c ,  25   d  to be released responsive to the candle container being tipped and/or struck by a force. In some implementations, one or more sensors  40   a ,  40   b ,  40   c ,  40   d ,  40   e ,  40   f , and/or other sensors may include one or more of a hair trigger, spring-loaded trigger, and/or other mechanical triggers and/or sensors. 
     By way of a non-limiting example,  FIG. 4  illustrates a side view of an exemplary implementation of an apparatus  10  configured for extinguishing a wick flame of a candle disposed in a candle container, in accordance with one or more implementations. As depicted in  FIG. 4 , sensors  40   c ,  40   d ,  40   e ,  40   f , and sensors  40   a ,  40   b  (not shown) may be configured to cause one or more control arms  25   a ,  25   b ,  25   c ,  25   d  to be released responsive to a detection of an impact. Furthermore, as shown in  FIG. 4 , one or more control arms  25   a ,  25   b ,  25   c ,  25   d  may be configured to cause the retractable lid halves  20   a  and  20   b  to close responsive to one or more control arms  25   a ,  25   b ,  25   c ,  25   d  being released. Responsive to first half  20   a  and second half  20   b  being in the closed position, the wick flame may be deprived of oxygen and the candle may be extinguished. 
       FIGS. 6-17  illustrate another exemplary embodiment of apparatus  10  that includes sensors such as sensors  40   a  . . .  40   n , control arms  25   a - 25   d , a mechanical timer  30 , and a manual override  35 . For purposes of clarity and brevity, like elements and components throughout the Figures are labeled with same designations and numbering as discussed with reference to  FIGS. 1-5 . Thus, although not discussed entirely in detail here below, one of ordinary skill in the art should understand that various features associated with the apparatus  10  as shown in and described with reference to  FIGS. 1-5  may be similar to those features previously discussed. Additionally, it should be understood that the features shown in each of the individual figures is not meant to be limited solely to the illustrated embodiments. That is, the features described throughout this disclosure may be interchanged and/or used with other embodiments than those they are shown and/or described with reference to. 
     As previously described, apparatus  10  as shown in  FIGS. 6-7  may include base  15  and retractable lid  20  configured to expand and enclose an opening of the candle container when the retractable lid is in a closed position (e.g., see  FIG. 7 ), and collapse and open for positioning adjacent to or around the opening when the retractable lid is in an open position (e.g., see  FIG. 6 ). A first half  20   a  and second half  20   b  may be stored on or adjacent to a first side and a second side of candle container  45 , respectively. The halves  20   a  and  20   b  may include ends that are configured to move in a generally upward direction relative to the opening  46  and towards each other to meet in the closed position. In some implementations, first half  20   a  and second half  20   b  may form individual halves of a semispherical retractable lid. For example, when in the closed position, the halves  20   a ,  20   b  of the retractable lid  20  may form a dome or similar shape over the opening  46 , such as shown in  FIG. 7 , for example. 
     The materials used to construct first half  20   a  and second half  20   b  have been discussed previously (e.g., a fire-safe material, metals, non-flammable materials. The first and second halves  20   a ,  20   b  may be configured to collapse accordion-style, e.g., such that portions are bent and stacked on top of each other. 
     In some implementations, first half  20   a  and second half  20   b  may each include a curved metal shaft  18  positioned at an end of each half  20   a  and  20   b  such that when the halves  20   a ,  20   b  are closed towards each other, the curved metal shafts  18  meet in the closed position of the retractable lid  20  (see  FIG. 7 ). Each curved metal shaft  18  may be of semi-circular configuration and positioned near, around, or on a side or lip of opening of the candle container  45  when the retractable lid  20  is in its open position, for example (see  FIG. 6 ). The shafts may be attached at or near the control arms  25   a ,  25   b ,  25   c , and  25   d . In some implementations, the shafts  18  are part of the control arms  25   a ,  25   b ,  25   c , and  25   d . In some implementations, the curved metal shaft may be compressed and retained under the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms when retractable lid  20   a  and  20   b  is locked in an open position. In one embodiment, the curved metal shafts  18  may lock with or be contained by a part of the base  15  when the lid  20  is locked in its open position. In some implementations, the curved metal shaft may be encased in a fire safe material. In some embodiments, the curved metal shafts may be embedded within fire safe material of the lid portions  20   a  and  20   b.    
     Movement of the halves  20   a  and  20   b  of the lid  20  into the open positon may cause the control arms  25   a - 25   d  to be spring-loaded via tensioning springs  36  provided about pivot points or arms  34  associated with the lid  20  and/or control arms  25   a - 25   d  (e.g., see  FIG. 8 ). The control arms  25   a - 25   d  may define the pivot points for each torsion spring  36  whose default or at rest position is to close the lid  20 . Accordingly, the first and second halves  20   a ,  20   b  may be pivotable or hinged between the open position and the closed position, and each of the halves  20   a  and  20   b  may include two pivoting points on opposite sides of the opening  46  when the apparatus  10  is positioned on the container  45  (see, e.g.,  FIGS. 9 and 10  showing points  25   a ,  25   c  associated with first half  20   a  of lid  20  and points  25   b ,  25   d  associated with second half  20   b  of lid  20 ). As represented in  FIG. 8 , for example, each spring  36  may be positioned around a point  34  or shaft (or as part of the curved metal shafts  18 ) (shown here, for example, as being associated with control arms  25   c  and  25   d ; arms  25   a ,  25   b  being understood to have similar construction), such that it is positioned externally around, on, or inside of the base (e.g., on first part  22 , discussed in greater detail below). An arm portion of the control arms may extend along at least a part or an edge of each lid half  20   a  and  20   b  (see  FIG. 10 ). For example, the curved metal shafts  18  may be a part of the control arms. The arm portion of the control arms may further include a small projection shaft that is connected at one of the connection points  34  of the control arm  25   a ,  25   b ,  25   c ,  25   d  and receives a tension spring  36  thereon. In use, after setting the timer  30 , when the lid  20  is opened, the halves  20   a  and  20   b  may be forced or moved to the open position such that the retractable lid is spring loaded via tension being added to the tensions springs  36  (e.g., through rotation of those springs). The tensed springs  36  store potential energy therein as they are tensioned against their resting state. The lid  20  is kept open and temporarily, releasably locked by the control arms  25   a - 25   d . This added/loaded spring tension assists the control arms  25   a - 25   d  in moving the first and second halves  20   a  and  20   b  to the closed position when they are released. Once unlocked, the spring tension is released and the springs  36  along with control arms  25   a - 25   d  assist in moving the lid  20  home to its closed position. 
     In accordance with an embodiment, the base  15  of the apparatus  10  includes multiple rings that assembled together and configured to be positioned around an opening, a mouth, or a lip of a candle container  45 . In one embodiment, the base  15  is secured around or adjacent the opening  46  and/or body of the container  45  via a retention device  14 , e.g., by adjusting and locking or clamping the retention device  14  such that the base  15  is secured thereto, near a top of the container  45  (as discussed previously).  FIG. 8  illustrates a detailed example of base  15  that includes a first part  22 , a second part  24 , a third part  26 , and a fourth part  28 . In an embodiment, the parts  22 - 28  are configured to be stacked atop one another and attached to one another such that they form the base  15 . The parts  22  may be separate and connected or attached together. One or more of the parts  22 - 28  may be integrally formed with another. In accordance with an embodiment, the shape of the base  15  and/or its parts  22 - 28  may correspond to a shape of the opening  46  of the candle container  45 . In one embodiment, the parts  22 - 28  have a substantially circular or ring shape, such as depicted in  FIGS. 9-16 . As discussed in detail below, in an embodiment, at least one part (e.g., third part  26 ) may be configured to move or rotate relative to the other parts of the base  15  (e.g., about a center axis of the candle container  45 ). 
       FIGS. 9-16  illustrate each of the first part  22 , second part  24 , third part  26 , and fourth part  28  in greater detail, the parts being shown in an exploded or disassembled view for explanatory purposes only. 
       FIG. 9  shows a top or overhead view of a first part  22  or ring with control arms  25   a - 25   d  (previously described) provided on opposite sides, e.g., in the depiction of  FIG. 9 , on a top and a bottom of the ring. In an embodiment, the first part  22  of the base  15  of apparatus  10  may be at least partially visible to a user when viewing the apparatus  10  from overhead. In one embodiment, the first part  22  is positioned to sit on or relative to the opening  46  of the candle container  45 . The part  22  may include one part of each of the retention mechanisms on the apparatus  10  that are used to hold the halves  20   a ,  20   b  of the retractable lid  20  in an open position. The retention mechanisms may be configured to join together at two points around the container, for example, i.e., there may be two retention mechanisms. Use of two retention mechanisms is exemplary only and not intended to be limiting; one or more than two mechanisms may be used. In an embodiment, the retention mechanisms may include retention arms  21   a ,  21   b  that may be provided on opposite sides of the first part  22 , e.g., in the depiction of  FIG. 9 , retention arm  21   a  is provided on a left side and a retention arm  21   b  is provided on a right side of the ring. The retention arms  21   a ,  21   b  may extend downwardly from a lower side of the first part  22  towards a bottom of the base  15 , such as shown in  FIG. 10 . In accordance with embodiments herein, the retention arms  21   a ,  21   b  may be provided on, against, outside, inside, or below the ring of part  22 . In an embodiment, each retention arm  21   a ,  21   b  may be substantially “S”-shaped, for example, with an upper part of each arm including a catch  27  and slot  29 , and a lower part having a lower slot and arm. First part  22  further includes the first and second halves  20   a ,  20   b  attached to an upper side thereof, as shown in the side view of  FIG. 10  (halves  20   a ,  20   b  not being shown in  FIG. 9  solely for explanatory purposes). 
     A lower part of the retention arms  21   a ,  21   b  of first part  22  may be configured to cooperate and interlock with a second part of the retention mechanisms, shown as retention clasps  32   a ,  32   b  (see  FIGS. 15 and 16 ) provided on fourth part  28  or ring. The catches  27  of the retention arms  21   a ,  21   b  are mechanically positioned to latch the lid in the open position when interlocked with clasps  32   a ,  32   b . The clasps  32   a ,  32   b  may be provided on opposite sides of the fourth part  28 , e.g., in the depiction of  FIG. 15 , retention clasp  32   a  is provided on a left side and a retention clasps  32   b  is provided on a right side of the ring. The retention clasps  32   a ,  32   b  may extend upwardly from the fourth part  28  towards a top of the base  15 , such as shown in  FIG. 16 . In an embodiment, each retention clasp  32   a ,  32   b  may be substantially hook- or “U”-shaped, for example, or shaped so to receive a lower portion of (the S-shape of) each retention arms  21   a ,  21   b , respectively. Retention arms  21   a ,  21   b  are configured to selectively interlock with the clasps  32   a ,  32   b , which are positioned below/at the bottom of the base (and may be pushed down to interconnect and snap or removably lock therewith). This provides for a more secure fit around the opening or mouth of the candle container  45 , as well as a more reliable opening and closing mechanism for the retractable lid halves  20   a  and  20   b . The shape and number of retention arms and retention clasps may correspond to and complement each other. In accordance with an embodiment, the retention arms  21   a ,  21   b  and clasps  32   a ,  32   b  are formed from complementary shapes, such that the arms and clasps may selectively and removably interlock with one another. In accordance with embodiments herein, when the mechanical timer is activated, the lid  20  is opened and the arms  21   a ,  21   b  and clasps  32   a ,  32   b  are configured to catch, interlock with and/or engage one another to assist or work together with the control arms  25   a - 25   d  for holding and keeping the lid  20  in its open position. In an embodiment, the arms  21   a ,  21   b  may be configured to drop into an interlocking engagement with clasps  32   a ,  32   b . In one embodiment, a user may apply pressure to the first part  22  to push and interlock the arms  21   a ,  21   b  into the clasps  32   a ,  32   b , such that the parts click together. In some embodiments herein, the arm and lower slot of lower portion of each retention arms  21   a  and  21   b  is configured to align or catch into upper slot and arm of clasps  32   a  and  32   b , so hold the retention mechanisms in place. 
     In accordance with an embodiment, as shown with reference to  FIG. 10  as well as  FIG. 8 , as the control arms  25   a - 25   d  (and thus lid halves) are lowered, at least a portion thereof is configured to catch underneath the catch  27 , in slot  29 , when the halves  20   a  and  20   b  are moved to the open position. This will simultaneously catch a lower slot of arms  21   a  and  21   b  into a slot or opening of clasps  32   a  and  32   b , such that the clasps  32   a  and  32   b  hold the arms  21   a  and  21   b  in place and the control arms  25   a - 25   d  and lid open. In one embodiment, the curved metal shafts  18  are part of the control arms  25   a - 25   d  and may lock with or be contained by a part of the base  15 , e.g., underneath catch  27  in slot  29 , when the lid  20  is locked in its open position. The lid portions  20   a  and  20   b  may remain locked under the catches  27  while the retention mechanisms of the first and fourth parts  22  and  28  are connected, i.e., until a predetermined time is countdown. Closing of the lid  20  is further described below with reference to sensors  40   a  . . .  40   n  and timer ring  30 - 1 , for example. 
     In one embodiment, such as shown in  FIG. 6 , the previously described retention device  14  may be provided on or associated with the fourth part  28  of the base  15  (e.g., a bottom part or ring). This allows at least the fourth part  28  to be adjusted and locked using the retention device  14 , thereby locking the base  15  to the container  45 . In an embodiment, the retention device  14  may be configured to adjusted each part  22 - 28  associated with the base  15 . 
       FIGS. 11-12  show an example of a second part  24  or ring of base  15  that is configured to be positioned below first part  22 . The second part includes a number of sides with multiple impact sensors  40   a ,  40   b ,  40   c ,  40   d ,  40   e ,  40   f ,  40   g ,  40   h ,  40   i , and  40   j  (or shock sensors) on an outer surface or outer side. The sensors  40   a - 40   j  are provided on an outer side of the base  15  such that impact or disturbance may be detected on the side of the candle container  45 , such as when the container  45  is knocked or tipped over. The sensors  40   a - 40   j  may be spaced around the opening  46 . In an embodiment, the sensors  40   a - 40   j  may be positioned just below opening  46  when the base  15  is attached to the container  45 . In one embodiment, the sensors  40   a - 40   j  are relatively and equidistantly spaced around the base  15  and thus the opening  46  of the candle container  45  when the apparatus is attached thereto. 
     As previously described, sensors  40   a - 40   j  are configured to cause the retractable lid to move from its open position to its closed position response to detection of an impact or disturbance. In accordance with an embodiment, each sensor  40   a - 40   j  is an impact sensor, i.e., a sensor that is mechanically triggered based on impact or force applied thereto. In an embodiment, each impact sensor  40   a - 40   j  may be interconnected with and/or configured to trigger a next or adjacent sensor(s). For example, if any one of the impact sensors  40   a - 40   j  is triggered, a chain reaction is set off, triggering all of the sensors to be triggered or activated. In one embodiment, each sensor is configured to trigger sensors adjacent or next to it, e.g., on either side, in response to a trigger or detection of impact. 
     More specifically,  FIG. 17  shows a detailed view, from the Z-direction, of a schematic example of parts of each impact sensor  40 , in accordance with an embodiment. A trigger portion  38  of each impact sensor  40   a - 40   j  extends generally in a horizontal direction (e.g., in the Z-direction), relative or parallel to a bottom of the candle container  45 . That is, when the base  15  is positioned on the candle container  45 , the trigger portion  38  of each impact sensor  40   a - 40   j  extends outwardly away from the opening/mouth/lip and away from a center, or wick, of the candle. Ledges  41  and shelves  43  are interconnected to the trigger portion  38  and generally provided on either side of each sensor, extending perpendicularly relative to the trigger portion  38 , e.g., in a lateral or horizontal direction therefrom. In an embodiment, each ledge  41  and shelf  43  may have a similarly shaped body (e.g., of polygonal, trapezoidal, triangular, etc.). Each shelf  43  further has a foot portion  48  that assists in triggering the associated sensors as well as triggering another sensor adjacent thereto. The foot portion  48  extends to a side or horizontally away from the body of the shelf  43  and towards the ledge  41 . (Alternatively, it should be understood that each ledge  41  may instead include a foot portion that extends towards a shelf  43 .) Each sensor  40   a - 40   j  also may include a push pin  42  that extends upwardly in a vertical direction (e.g., in the Y-direction). The sensors  40   a - 40   j  may generally extend towards first part  22  of the base  15 . As schematically depicted in  FIG. 18 , force F or pressure that is applied against an outer surface of the trigger portion  38 , i.e., in a direction towards the center or wick of the candle container, or in the Z-direction (such as when the container is knocked over), causes the trigger portion  38  to move (backwards towards the container in the Z-direction, or left, as depicted in  FIG. 18 ). This movement of the trigger portion  38  causes or pushes the ledge  41  and shelf  43  to move horizontally or laterally relatively away from one other (see arrows B in  FIG. 17 ) in the sensor by applying relatively equal pressure on push-pins  42  in the Y-direction and to bodies of the ledge  41  and  43  in the X-direction. However, the movement of the ledge  41  and shelve  43  will act upon adjacent ledges  41  and shelves  43  of the other sensors on either side or adjacent to that sensors, thus pushing an array of push-pins  42  upward. That is, each of the ledge  41  and shelf  43  interact with an adjacent ledge  41  and shelf  43  of another sensor to push up a push pin  42 . For example, as ledge  41  is pushed in an X-direction away from its associated shelf  43  in its sensor  40 , ledge  41  acts on an adjacent shelf  43  of an adjacent or next impact sensor in the series. In the absence of force on trigger portion  38  on the adjacent sensor, then, pressure from ledge  41  acts on the adjacent shelf  43  and moves its foot portion  48  towards and in contact with the ledge  41  of the adjacent sensor. This movement of the adjacent shelf  43  of adjacent sensor causes the push-pin  42  of that sensor to receive pressure (e.g., from an edge of the body of that shelf  43 ) and move vertically, in addition to moving, via its foot portion  48 , the adjacent ledge  41  towards the next sensor. Accordingly, a chain reaction is caused to the series of sensors  40   a  . . .  40   n  by impacting a single sensor. 
     The movement of each of the push pins  42  in the vertical or upward direction causes pressure to the first part  22  or ring and in turn causes the retention arms  21   a ,  21   b  to release from the retention clasps  32   a ,  32   b . In some embodiments, the arms  21   a ,  21   b  may be flexed or rocked along the Z-direction to disengage its lower portion from slots of the clasps  32   a ,  32   b . In some embodiments, the arms  21   a ,  21   b , may be pushed or moved laterally out of the slots of clasps  32   a ,  32   b . In other embodiments, a portion of the arms  21   a ,  21   b  may be pivoted out of engagement with clasps  32   a ,  32   b . In accordance with some embodiments, the clasps  32   a ,  32   b  may be moved, flexed, rocked, pivoted, etc. out of engagement with the arms  21   a ,  21   b . In yet another embodiment, one of the parts  22  or  28  may be rotated slightly (e.g., one to two degrees) relative to the other to disengage the retention mechanisms. Accordingly, the movement or method of releasing the retention mechanisms (i.e., arms  21   a ,  21   b  and clasps  32   a ,  32   b ) is not intended to be limited. In an embodiment, upon release of the push pins  42  of the sensors  40   a - 40   j , each is configured to apply a substantially uniform or consistent force upward to separate the retention arms  21   a ,  21   b  from the retention clasps  32   a ,  32   b.    
     By way of this impact array, any disturbance to the candle container from any orientation will trigger the retention arms to release, thus allowing the lid portions  20   a  and  20   b  to release from the catch  27  and move towards one another to their closed position, extinguishing the flame in a safe and timely fashion. 
       FIGS. 13 and 14  shows a third part  26  in the form of a timer ring  30 - 1  or collar with release arms  31   a ,  31   b  positioned opposite to one another, i.e., on either side of the base  15 . The timer ring  30 - 1  may be positioned below the first part  22  and relatively on top of fourth part  28 , as shown in  FIG. 8 , for example. As depicted in  FIG. 13 , i.e., release arm  31   a  on a left side and release arm  31   b  on a right side of the ring, the release arms  31   a ,  31   b  are positioned at a zero position, i.e., preventing opening of the halves  20   a ,  20   b . In accordance with embodiments herein, in order to move the retractable lid  20  and its halves  20   a ,  20   b  to an open position, the arms  31 ,  31   b  must be moved or rotated. The timer ring  30 - 1  may lock the lid  20  in its closed position until it is moved. In accordance with an embodiment, if the timer ring  30 - 1  is at zero, the retention arms  21   a ,  21   b  are mechanically prevented from latching the lid in the open position (as their lower portions are not interlocked with clasps  32   a ,  32   b ). Movement of the arms  31   a ,  31   b  allows the halves  20   a ,  20   b  to pivot or rotate to their open position, and arms  21   a ,  21   b  and clasps  32   a ,  32   b  may latch and engage. In accordance with an embodiment, the timer ring  30 - 1  is configured to be turned or rotated (e.g., in a clockwise direction about a center axis, as shown by arrow C in  FIG. 13 ) to wind the timer device for a predetermined time period. Upon being wound, the release arms  31   a ,  31   b  are also moved or rotated away from the location of retention arms  21   a ,  21   b  (e.g., in the clockwise direction), thereby allowing the arms  21   a ,  21   b  to interlock with the clasps  32   a ,  32   b . After being wound, the timer ring  30 - 1  rotates (e.g., in a counter clockwise direction), to control a countdown of the selected predetermined time period, around an opening  46  of the candle container  45 , moving its release arms  31   a ,  31   b  therewith around the opening, towards their zero position. 
     As generally depicted in  FIGS. 6 and 7 , apparatus  10  may include a manual over-ride  35 , as previously described, for releasing the control arms  25   a ,  25   b ,  25   c ,  25   d , independently of the mechanical timer or timer ring  30 - 1 . In some implementations, the manual over-ride  35  is associated with the timer ring  30 - 1 . In some implementations, it is associated with any number of parts  22 - 28  of the base  15 . The location and position of the manual over-ride  35  is not intended to be limiting. Upon triggering of the manual over-ride  35 , for example, the retention mechanisms (e.g., arms  21   a ,  21   b  and clasps  32   a ,  32   b ) may be released, and the one or more control arms  25   a ,  25   b ,  25   c ,  25   d , and/or other control arms may be released. Thus, the retractable lid  20   a  and  20   b  may be caused to close extinguishing the flame independent of timer ring  30 - 1 . 
     For example, in accordance with an embodiment, the manual override  35  is provided in the form of a button on the base  15 , e.g., associated with or on the timer ring  30 - 1 , and associated with control arms  25   a - 25   d.    
     If no impact occurs or is detected by one or more of the sensors  40   a - 40   j , normal operation will proceed with the timer ring  30 - 1  completing its cycle down to zero, after which the release arms  31   a ,  31   b  attached to the timer ring  30 - 1  are positioned and configured to forcibly separate the retention arms  21   a ,  21   b  above from the retention clamps  32   a ,  32   b  below, releasing the halves/left cover  20   a  and the right cover  20   b , allowing the spring-loaded control arms  25   a - 25   d  to close the covers towards each other, thereby limiting the amount of oxygen and extinguishing the candle flame. 
       FIG. 5  illustrates a method  500  for extinguishing a wick flame of a candle disposed in a candle container. The operations of method  500  presented below are intended to be illustrative. In some implementations, method  500  may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of method  500  are illustrated in  FIG. 5  and described below is not intended to be limiting. 
     At an operation  505 , a candle-timer base is coupled to a candle container, such as container  45 . The candle-timer base may be the same as or similar to base  15  (shown in  FIG. 1  and described herein). 
     At an operation  510 , a predetermined time period may be set on a mechanical timer. The mechanical timer may be the same as or similar to mechanical timer  30  shown in  FIG. 1  and described herein or the timer ring  30 - 1  shown and described with reference to  FIGS. 6-7 and 13-14 . 
     At an operation  515 , a retracting lid of the candle-timer is opened responsive to the predetermined time period being set on the mechanical timer  30 . In some implementations, the retracting lid may include a first half and a second half. In some implementations, the first half and the second half may be stored on a first side and second side of a candle container respectively while in the open position. The first half and the second half may be the same or similar to first half  20   a  and second half  20   b  respectively (e.g., such as shown in  FIG. 1  or  FIG. 6 , and described herein). 
     At an operation  520 , responsive to the retractable lid being in the open position, a user may light the candle. 
     At an operation  525 , the retractable lid is closed responsive to expiration of predetermined time of the mechanical timer. In some implementations, the retractable lid may be closed responsive to one or more control arms being released by the mechanical timer. The one or more control arms may be the same or similar to control arms  25   a ,  25   b ,  25   c , and/or  25   d  (shown in  FIG. 1  and described herein). 
     At an operation  530 , the retractable lid is closed responsive to a manual over-ride being triggered. The manual over-ride may be the same or similar to manual over-ride  35  shown in  FIG. 1  and described herein or the manual over-ride  35  shown and described with reference to  FIGS. 6-7 . 
     At an operation  535 , the retractable lid is closed responsive to a detection of an impact. In some implementations, one or more sensors may be configured to cause the one or more control arms be released responsive to the candle container being tipped and/or struck by a force. The one or more sensors may be the same or similar to sensors  40   a ,  40   b ,  40   c ,  40   d ,  40   e , and/or  40   f  shown in  FIG. 1  and described herein or the sensors  40   a  . . .  40   n  shown and described with reference to  FIGS. 6-7, 11-12 , and  17 - 18 . 
     Responsive to the retractable lid being closed in any of operations  525 ,  530 , and/or  535 , wick flame may be deprived of oxygen such that the candle is extinguished. 
     The embodiments of the herein disclosed apparatus  10  may be used with different types of candles and candle holders and is not limited in size or height with regards to the type(s) of candles &amp; holders it may support. 
     Utilizing first half  20   a  and second half  20   b  attached to the container via control arms  25   a - 25   d  to form a lid and seal the candle container allows for certain safety elements to be integrated into the closing mechanism that cannot readily be achieved with prior art devices (e.g., such as those that include a single attachment point or single hinge point). 
     Affixing the disclosed apparatus  10  to the top of the candle/holder/enclosure ensures additional safety features should the candle enclosure be moved or knocked over intentionally or accidentally. For example, the herein described impact sensors may be interconnected with one another to cause a chain reaction of the sensors and close the lid. The sensors  40   a - 40   n  as provided on the apparatus do not require that the candle/candle container  45  be disturbed in a specific manner or orientation with regards to releasing the safety mechanism to function as intended. 
     In addition, embodiments of the herein disclosed apparatus  10  may be retrofit to any number of manufactured candle containers (e.g., jar candles) or candle containers configured to receive a candle therein (e.g., a container that receives a votive candle) using a retention mechanism. That is, the apparatus  10  may be positioned on upwardly facing openings or lips of any type and size of candle containers, and secured thereto. By affixing the apparatus to the top or opening of the candle/holder via an adjustable retention strap/clamp, such as by using base  15  and retention device  14 , it can support candles of any height or size (i.e., diameter of the candle or candle holder) and provide a universal fit to such containers. 
     Although the present technology has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred implementations, it is to be understood that such detail is solely for that purpose and that the technology is not limited to the disclosed implementations, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present technology contemplates that, to the extent possible, one or more features of any implementation can be combined with one or more features of any other implementation.
