Abstract:
A universal bottle that interfits into a plurality of different housings for liquid vaporization devices. Two of the current commercial devices have specially constructed bottles that are not interchangeable, that is, the bottle intended for use with one of the commercial devices cannot be used with the other device and vice versa. The present bottle is dimensioned so as to interfit into both of the commercial devices and has a neck having an opening and two sets of opposite external surfaces that are dimensioned so that in one orientation, the bottle will fit into one of the commercial devices, and, by rotating the bottle a predetermined amount to another orientation, the bottle can be operatively inserted into the other of the commercial devices. In each instance, a locking system on the bottle cooperates with the housing of the commercial device to retain the bottle in its operative position.

Description:
BACKGROUND 
     The present invention relates to liquid vaporization devices and, more particularly, to a device that vaporizes a liquid perfume and to a specialized bottle that can be used therewith. 
     There are, of course, a number of commercial devices currently on the market that are capable of vaporizing an aroma producing liquid in order to freshen a room and to rid that room of annoying and undesirable odors. Of the typical commercial devices, there is the type that includes a housing that receives a liquid containing bottle such that the user can employ the device to vaporize the liquid within the bottle and, when the supply of liquid within a particular bottle has been expended, the user can simply remove the empty bottle and replace it with a full bottle to continue the utilization of the device. As such, the typical device comprises a housing having a heater contained therein and which interacts with a wick extending upwardly from the bottle. 
     The heater, therefore, must be in close proximity to the wick when the bottle is interfitted to the housing so that the heater for that device can effectively and efficiently vaporize the liquid that is present in the wick. In some vaporizing devices, the heater is an annular unit that surrounds the wick and therefore it is critical, in such devices, that the wick be properly positioned with respect to the heater and be capable of easily and automatically be located in such position when a bottle is inserted in to the vaporization device. The heater warms the wick, thereby enhancing the vaporization process, and which also draws that liquid upwardly from that bottle. The bottle itself therefore requires an opening at the top surface such that the wick can extend upwardly through that opening and into the housing of the particular vaporization device so that the wick is properly aligned with the heater. 
     One of the drawbacks to current liquid vaporization devices, however is that each bottle is unique to a particular housing, that is, once the consumer has purchased a liquid vaporization device, there is a limited market to the purchase of replacement bottles and only a certain bottle will interact with a housing of any individual manufacturer. For example, two of the popular commercial liquid vaporization devices currently on the market are the Wizard device distributed by Reckitt Benckiser, Inc, of Wayne, N.J. and the Glade device manufactured by S.C. Johnson and Son of Wisconsin. Each device has different dimensions of its housing that accepts a bottle filled with liquid perfume and each bottle is differently dimensioned such that the bottle presently sold to be used with the Glade device cannot be used with the Wizard device and vice versa. 
     Not only are there dimensional differences, but with the Wizard device, the bottle has an annular collar that is snap fitted to a movable member to retain the bottle in its operative position to the housing and there is a release mechanism that moves that movable member to release the bottle therefrom. As such, with the bottle adapted to be interfitted to the Wizard device, there needs to be a annular collar that is dimensioned so as to properly cooperate with the snap in and release mechanism. In addition, with the Wizard unit, as with other bottles, and as explained, the location of the opening in the bottle through which the wick extends, is important and in the Wizard device that bottle opening is off center, that is, it is not centered between the front and rear surfaces of the bottle as it is positioned within the housing of the Wizard device. As used herein, the rear surface of a bottle is the surface that faces the vaporization device and the front surface faces outwardly away from that device. 
     Accordingly, with the Wizard device, taking a dimension of the bottle along a centerline or plane extending at a right angle to the rear surface of the housing such that the centerline passes through the front surface of the bottle and the rear surface of the bottle, the opening for the wick, and, of course, the wick itself, is located closer to the rear surface than the front surface. 
     With the Glade device, the location of the opening in the upper surface of the bottle is in an entirely. different position with respect to its front and rear surfaces and, again, such location is essential to the proper interfitting of the bottle into the housing of the Glade device. Thus, in the Glade device, the location of its opening, and, of course, the corresponding wick that extends upwardly from the opening, is positioned approximately centered between its front and rear surfaces. With the bottle used in the Glade device, the bottle also has two oppositely disposed projections that interfit into corresponding shaped openings in the housing so that the projections snap into the openings in the housing to retain the bottle in its operative position and the bottle can be snapped out of that position by the inherent flexibility of the housing. Those projections are, therefore, formed in the front and rear surfaces of the bottle for the Glade device, and, therefore, generally at equal distances from the centerline of the opening in the upper surface of the Glade bottle. 
     As can be seen, the differences in the current bottles for the Glade and Wizard devices, be it based upon the dimensions of the external surfaces or in the location of the opening for the wick, makes the bottles that interfit into those devices unique to each intended device and the interchangeability not possible, that is, a bottle intended for a Glade device simply cannot be used with a Wizard device and vice versa. 
     Accordingly, the consumer cannot have the versatility of having a differing brand of vaporization devices without having to make sure the proper bottle is purchased for that specific vaporization device and it is possible for the consumer to actually purchase the incorrect bottle and thus be thwarted in the desire to replace an existing, empty bottle. In addition, the consumer is sometimes inconvenienced in that a local store may stock only one brand of liquid vaporization device and which is not compatible with the device that is being used by the consumer, thereby requiring the consumer to locate another supplier of the correct bottle. 
     In addition, aside from the lack of versatility in purchasing bottles that are specific to a particular vaporization device, it is more convenient for the consumer to have the ability to purchase a range of scents, and a particular desired scent may be available only from a competing manufacturer of the consumers devices and therefore the consumer cannot use that particular scent due to the incompatibility of the bottle containing that scent with the device in use by the consumer. 
     In any event, it would be advantageous for the consumer to be able to purchase a single bottle that is compatible physically with more than one brand of liquid vaporization device so that such consumer can simply purchase the bottle having the desired scent and be able to use that bottle irrespective of the brand of the liquid vaporization device used by the consumer. 
     SUMMARY OF THE INVENTION 
     Accordingly, the present invention relates to a liquid vaporization device and bottle that interfits therewith and to a specially constructed bottle that can fit into any of a plurality of housings of such vaporization devices and, at least into those housings of the Glade and the Wizard liquid vaporization devices. 
     Accordingly the bottle of the present invention has solved the lack of interchangeability of the aforementioned bottles for the commercial Glade and Wizard liquid vaporization devices by providing a neck having an opening along with a plurality of front and rear external surfaces that are selectable by the user, that is, the bottle is capable of being utilized in a multiplicity of orientations with respect to the particular housing of a liquid vaporization device. 
     The bottle of this invention can be oriented in one position wherein the opening is centrally located between the front and rear surfaces of the bottle as it is interfitted to the Glade liquid vaporization device with the front and rear surfaces additionally having projections extending out therefrom to snap within corresponding alignment holes in the Glade housing for that device. Thus, in such orientation, the bottle is well adapted to be interfitted to the Glade device. 
     By rotating the present bottle a predetermined amount, or number of degrees, a different front and rear surface is presented and where the upwardly facing opening is now closer to the rear surface than the front surface, i.e. offset from the center location between the front and rear surfaces, and is therefore adapted to be interfitted to the housing of the Wizard liquid vaporization device. There is additionally formed an annular collar so that the bottle, in this orientation, can be interfitted to and held in the housing of a Wizard device. 
     Thus, by simply rotating the bottle, two different sets of front and rear surfaces are utilized, each having the proper characteristics, dimensions and features necessary for the proper fitting of the bottle into either the Glade of the Wizard device and with the opening located in the proper positioned to operate with that particular device. With each orientation, the bottle includes a locking feature that cooperates with a corresponding feature on the Glade or Wizard device housing to retain the bottle in its operative position. In the preferred embodiment, that amount of rotation used to orient the bottle with the differing front and rear surfaces to carry out the present invention is 90 degrees. 
     Additional features and advantages of the invention will become apparent to those skilled in the art upon consideration of the following detailed description of preferred embodiments exemplifying the best mode of carrying out the invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to FIG. 1, there is shown a perspective view of a bottle  12  constructed in accordance with the present invention. In FIG. 1, it can be seen that there are basically four external surfaces to the bottle  12 . For purposes explaining the present invention the external surfaces are defined in FIGS. 1-3 as a first external surface  14 , a second external surface  16 , a third external surface  18  and a fourth external surface  20 . The first external surface  14  is preferably arcuate in configuration, that is, it is curved outwardly, while the surfaces of second, third and fourth external surfaces  16 ,  18 , and  20 , respectively, are generally planar, however, it will become apparent that any of the external surfaces may be arcuate or planar and still be within the spirit of the present invention. As an example, in the preferred embodiment, the width of the first and third external surfaces  14 ,  18  is about 32.3 mm. while the width of the second and fourth external surfaces  16  and  20  is about 35.6 mm. 
     A neck  22  extends upwardly for the upper surface  24  of the bottle  12  and the neck  22  is preferably provided with external threads  26  so that a protective cap (not shown) may readily be secured to the bottle  12  to contain the contents of the bottle  12  prior to use. In the preferred embodiment, the overall height of the bottle  12  from the bottom of the bottle  12  to the top of the neck  22  is about 52 mm. There is an opening  28  that passes through the neck  22  to communicate with the interior of the bottle  12 , and, as will be later explained, a wick is adapted to extend upwardly through the opening  28  so that a liquid contained within the bottle  12  can pass through the wick to be vaporized to the atmosphere. 
     There is also formed integral with the neck  22  an annular collar  30  that is dimensioned to be a predetermined diameter and location on the bottle  12  for purposes that will also be later explained. There are also a pair of outwardly extending projections  32  that are formed in the second and fourth external surfaces  16 ,  20  and are oriented opposite each other and generally in alignment with the opening  28  in the neck  22 , that is, the longitudinal center line C of the opening  28  and the center line joining the projections  32  would be in the same plane. 
     Taking FIG. 2 in connection with FIG. 1, it can be seen that the center line C of the opening  28  is also oriented about midway between the second and fourth external surfaces  16 ,  20 , show by the distances D in FIG.  2 . 
     Turning now to FIG. 3 in connection with FIG. 1, it can also be seen that the centerline C of the opening  28  is offset with respect to the midpoint between the first and third external surfaces  14  and  18 . For example in FIG. 3, the mid point between the first and the second external surfaces  14  and  18  is shown as point M and the centerline of the opening  28  is offset with respect to that mid point M by a predetermined dimension d. FIG. 3 also shows the alignment between the centerline of the projections  32  and the centerline C of the opening  28 . In the preferred embodiment, the approximate distance from the second external surface  18  to the centerline C is about 23.1 mm and from that centerline C to the first external surface  14  is about 12.5 mm. 
     Turning now to FIGS. 4A and 4B, there is shown front views of a commercial liquid vaporization device having a housing  34  that is basically typical of the Glade device that is currently on the market. In FIG. 4A, there is a standard prior art bottle  36  currently sold with or sold to be used with the Glade device and is affixed in its operative position to the housing  34  and in FIG. 4B, there is affixed to the housing  34  the bottle  12  constructed in accordance with the present invention. 
     Taking FIG. 4A first, it can be seen that the housing  34  includes a annular heater  38  that surrounds the wick  40  extending upwardly from the bottle  36 . Thus, when the bottle  36  is in its operative position, as shown, the wick  40  passes through the annular heater  38  so that the heater  38  can heat the volatile liquid within the wick  40  and vaporize that liquid to be exhausted into the surrounding environment. 
     The housing  34  also includes two alignment holes  42  (only one of which is shown in FIG. 4A) that are oppositely oriented such that two projections  44  on the bottle  36  can be snapped into the alignment holes  42  as the bottle  36  is inserted into its operative position within the housing  34  to hold the bottle  36  in that operative position and, by predetermining the dimension A, it is assured that the wick  40  is sufficiently long so as to pass sufficiently through the annular heater  38  when the lower edge of the projections  44  are snap fitted into the corresponding alignment holes  42 . 
     Thus, in FIG. 4B, the same housing is used as representative of the Glade liquid vaporization device and therefore the dimension A is still important to assure that the wick  46  of the bottle of this invention is sufficiently long to pass within the annular heater  38 . Also of critical dimension, and referring also back to FIGS. 1 and 3, in FIG. 3 the bottle  12  is shown in the same orientation as in the front view of FIG. 4B such that the wick  46  extending from the opening  28  is located at the midpoint between the front external surface  48  and the rear external surface (not shown in FIG.  4 B). To put the orientation in perspective, and referring to FIGS. 1-3 and  4 B, the front external surface  48  is the external surface that faces away from the housing  34  and is, in effect, the second external surface  16  of FIGS. 1-3 and the rear surface of FIG. 4B, not shown in FIG. 4B, that is, the external surface facing the housing  34  is the fourth external surface  20  of FIGS. 1-3. As can also be seen, the bottle  12  can be rotated 180 degrees and still interfit within the housing  34 , that is, the bottle  12  would be a mirror image of the bottle  12  shown in the orientation of FIG.  4 B. 
     Therefore, in order to fit within the housing  34  of the Glade liquid vaporization device, the bottle  12  must be orientated such that the second external surface  16  or the fourth external surface  20  of FIGS. 1-3 is the front surface  48  of FIG.  4 B and the fourth external surface  20  or the second external surface  16  of FIGS. 1-3 is the rear external surface of the bottle of FIG. 4B, that is, the bottle  12  can be placed in the Glade device in either of two positions that are 180 degrees apart. 
     Turning now to FIGS. 5A and 5B, there is shown side views of a commercial liquid vaporization device having a housing  52  that is basically typical of the Wizard device that is currently on the market. In FIG. 5A, there is a standard prior art bottle  54  currently sold to be used with the Wizard device and is affixed in its operative position to the housing  52  and in FIG. 5B, there is affixed to the housing  52  the bottle  12  constructed in accordance with the present invention. 
     Taking FIG. 5A first, it can be seen that the housing  52  includes an annular heater  56  that surrounds the wick  58  extending upwardly from the bottle  54 . Thus, when the bottle  54  is in its operative position, as shown, the wick  58  passes through the annular heater  56  so that the heater can heat the volatile liquid within the wick  58  and vaporize that liquid to be exhausted into the surrounding environment. 
     The housing  52  also includes downwardly extending latches  60  that grasps the bottle  54  underneath the annular collar  64  formed in the neck  66  of the bottle  54 . The interaction between the downwardly extending latches  60  thus holds the bottle  54  in its operative position as show in FIG.  5 A. Again, by predetermining the dimension A, it is assured that the wick  58  is sufficiently long so as to assure that the wick  58  passes through the annular heater  56  when the downwardly extending latches  60  have securely grasped and are holding the bottle  54  in the operative position as shown in FIG.  5 A. 
     Thus, in FIG. 5B, the same housing is used as representative of the Wizard liquid vaporization device and therefore the dimension A is still important to assure that the wick  46  of the bottle of this invention is sufficiently long to pass within the annular heater  56 . Also of critical dimension, and referring also back to FIGS. 1 and 2, in FIG. 3 the bottle  12  is shown in the same orientation as in the side view of FIG. 5B such that the wick  46  extending from the opening  28  is located offset rearwardly in the housing  52  from the point M that is the midpoint between the front external surface  48  and the rear external surface  50 . To put the orientation in perspective, and referring to FIGS. 1-3 and  5 B, the front external surface  48  is the external surface that faces away from the housing  52  and is, in effect the third external surface  18  of FIGS. 1-3 and the rear external surface  50  of FIG. 4B, i.e. the external surface facing the housing  52 , is the first external surface  14  of FIGS. 1-3. 
     Therefore, in order to fit within the housing  52  of the Wizard liquid vaporization device, the bottle  12  must be orientated such that the third external surface  18  of FIGS. 1-3 is the front surface  48  of FIG.  5 B and the first external surface  14  of FIG. 1-3 is the rear external surface  50  of the bottle  12  of FIG.  5 B. 
     Therefore, it can be seen that the present bottle  12  can be interfitted into the Glade vaporization device or the Wizard vaporization device by simply rotating the bottle  12  so that the proper external surfaces are in the correct orientation with respect to the particular commercial device, be it the Glade device or the Wizard device. 
     To summarize, with the present bottle  12 , it is possible to interfit that bottle  12  into either the housing  34  of the Glade device as shown in FIGS. 4A and 4B or the Wizard device as shown in FIGS. 5A and 5B by simply rotating the bottle about its centerline C passing through the opening  28  and the neck  22  so that different external surfaces are facing toward and away from the housing  34  and  52 . For example, when the bottle  12  is intended to be interfit into the housing  34  of the Glade device, the bottle is oriented such that the second and fourth external surfaces  16  and  20  as shown in FIGS. 1-3 are, respectively, the front and rear surfaces of the bottle  12  when operatively interfitted with that Glade device and shown in FIG.  4 B. On the other hand, to interfit the same bottle  12  into the Wizard device, the bottle  12  is simply rotated 90 degrees and inserted into the Wizard device such that the first external surface  14  and the third external surface  18  of FIGS. 1-3 are, respectively, the rear surface  50  and the front surface  48  of the bottle  12  when in the operative position in that Glade device, shown in FIG.  5 B. 
     Accordingly, the present bottle  12  has been specifically dimensioned to be able to be interfitted with either the Glade device or the Wizard device through the rotation of the bottle  12  such that the proper dimensions are in the correct location to insert that bottle  12  into either device and thus the same bottle can be sold commercially at a greater convenience to the user. It should be noted, that the present bottle can only be interfitted to the Wizard unit in one orientation and can thereafter be interfitted to the Glade device by a 90 degree rotation of the bottle  12  in either direction, that is, the bottle  12  can fit into the Glade device in two orientations, about 180 degrees apart, with either the second external surface  16  or the fourth external surface  20  facing outwardly. 
     Those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the liquid vaporization device and bottle which will result in an improved device and method of using the same yet all of which will fall within the scope and spirit of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the following claims and their equivalents.
