## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to U.S. Provisional Application Ser. No. 62/051,378 filed Sep. 17, 2014, entitled “Closure Locking Assembly,” the entire contents of which is incorporated herein in its entirety.


FIELD
This disclosure relates to a closure locking assembly. More particularly, this disclosure relates to a closure locking assembly for pharmaceutical containers that prevents a user from removing a closure with respect to a container.
BACKGROUND
Many child-resistant closure systems, or reversible child resistant closure systems in the child resistant configuration, require a user to push-down-and-turn the closure with respect to a container to remove the closure from the container. For example, U.S. Pat. No. 5,499,078 describes a push-down-and-turn container system having a container with a plurality of locking lug receivers on the outer circumference of the neck/rim of the container and a closure having a circumferential sidewall with corresponding locking lugs along the inner surface of the sidewall. To install the closure to the container, the locking lug receivers 10 each include a tapered ramp 12 as shown in FIG. 1 herein that guides the locking lugs of the closure into a notch 14 of the locking lug receiver 10 upon rotation of the closure. As shown, the notch 14 is formed between the tapered ramp 12 and a vertical member 16 of the locking lug receiver 10. Engagement of the locking lugs with the corresponding locking lug receivers 10 prevents the closure from being turned in the counter-clockwise direction, and thus prevents the closure from being removed from the container 1.
In order to remove the closure from the container 1, the user must apply downward pressure to the closure to disengage corresponding locking lugs 9 (as best shown in FIG. 4) of the closure from the locking lug receivers 10 of the container 1, then turn the closure such that the locking lugs 9 are disposed in an open area 18 between adjacent locking lug receivers 10, and finally lift the closure from the container 1. Thus, these types of closure systems are commonly referred to as push-down-and-turn systems.
Similarly, as exemplified in U.S. Pat. No. 8,662,331, many child resistant closure systems include a deflectable locking structure disposed along a rim on the neck of the container for releasably engaging a locking lug of the closure. To remove this closure from the container, the user pushes down on the deflectable locking structure of to disengage the locking lug of the closure.
While these types of closure systems are generally effective in preventing a child from removing the closure from the container, it is not impossible for children to open the containers (hence the name “child resistant”). In particular, a child playing with the closure system may apply downward pressure to the closure resulting in disengagement of the locking lugs from the locking receivers. Once the locking lugs are disengaged, it is generally easy to intentionally or unintentionally remove the closure from the container. Also, the child may even figure out how to open the container, such as by watching their parents or even reading instructions on top of the closure, and then be able to do so on their own.
What is needed therefore is at least an option for the user to apply an enhanced locking system to the closure system.

DETAILED DESCRIPTION
The disclosure relates to a locking assembly for preventing undesired opening of a closure system, particularly by children. “Closure system” or “closure assembly” as used herein refers to a closure as installed on a container to close the container opening. The locking assembly of the present disclosure is primarily directed for use with closure systems intended to store and dispense pharmaceutical products, and particularly prescription pharmaceuticals. However, the locking assembly may also be used with other types of closure systems in which an enhanced child proof closure is desired such as closure systems for household cleaners, solvents, vitamins, etc.
One embodiment of the child proof locking assembly 20 of the present disclosure is exemplified in FIGS. 2-9. Referring to FIGS. 2-4, the locking assembly 20 is preferably operable to be secured across the top surface 4 and around the circumferential sidewall 6 of a closure 2. In order to install or remove the locking assembly 20 from a closure system, the locking assembly 20 is adjustable between an unlocked/expanded position (FIG. 2) and a locked position (FIGS. 3-4). While in the locked position, the locking assembly 20 is dimensioned and configured to tightly grip the top surface 4 and underneath opposing sides of the sidewall 6 of the closure 2. In this regard, the locking assembly 20 in the locked position generally includes a horizontal member 22 traversing the top surface 4 of closure 2 and two vertical members 24 extending downward from opposite ends of the horizontal member 22 and abutting opposing sides of sidewall 6 of closure 2. In order to tightly grip opposing sides of the sidewall 6, the vertical members 24 are preferably rounded to conform to the circumferential sidewall 6 of the closure 2 and container 1. As shown in FIG. 2, the horizontal member 22 is preferably operable to expand lengthwise to achieve the unlocked position to remove the locking assembly 20 from a closure system. However, it should be understood that the locking assembly 20 may be removed from a closure system in other manners such as one or both of the vertical members 24 being operable to expand away or be removed from the horizontal member 22.
Referring to FIG. 4, the vertical members 24 each include a hooking element 28 that extends from a distal end of the vertical member 24 in a horizontal direction substantially parallel to the horizontal member 22. Accordingly, hooking elements 28 are disposed beneath a bottom edge 7 of opposing sides of the sidewall 6 of closure 2 in the locked position. In preferred embodiments, as shown in the cross sectional view of FIG. 5A where the locking assembly 20 is installed on a closure system in the locked position, hooking elements 28 are dimensioned and configured such that they extend from their respective vertical members 24 until the distal end of the hooking elements 28 abut the container sidewall 19 in order to prevent outward deflection of the vertical members 24 and/or prying open of the locking assembly 20 by an unintended user when the locking assembly 20 is in the locked position on a closure assembly.
When the locking assembly 20 is positioned on a closure assembly in the locked position, the hooking elements 28 prevent the closure 2 from being removed from the container 1 by “hooking” underneath portions of a container that extend radially outward from the container sidewall 19. For example, referring to a closure system such as U.S. Pat, No. 5,499,078 described above having a plurality of locking receivers 10 extending from the neck of the container 1 as shown in FIG. 1, the hooking elements 28 prevent the closure 2 from being raised with respect to the container 1 by being wide enough such that at least a portion of each hooking element 28 is always disposed underneath at least a portion of at least one locking receiver 10. As another example, when the container includes a rim extending from the sidewall of the container as exemplified in U.S. Pat. No. 8,662,331, the hooking elements 28 prevent the closure from being raised with respect to the container due to the hooking elements 28 being disposed underneath the container rim in the locked position. Accordingly, when a user attempts to open a closure system with a locking assembly 20 secured thereto in the locked position, the hooking elements 28 are configured to contact the locking receivers 10, a rim, or any other portion of the container that extends from the container sidewall 19 to prevent the user from removing the locking assembly and/or raising the closure with respect to the container.
Referring to FIG. 4 and FIG. 5A, to assist in securing the locking assembly 20 to the closure 2 in a tight gripping position, the closure 2 may also include indentions 8 that receive tab protrusions 26 extending from the interior surface of the vertical members 24. It should be understood that the indentions may take various forms including notches, slots, apertures, etc. In embodiments where the closure 2 includes a plurality of locking lugs 26 for engaging a plurality of locking receivers 10 of the container as described in U.S. Pat. No. 5,499,078, the indentions 8 are preferably apertures and the corresponding protrusions 26 are preferably positioned such that the protrusions 26 extend into the space 18 between adjacent locking lug receivers 10 when the closure 2 is correctly installed on the container 1 in the child resistant position. On the other hand, when the closure 2 is not properly installed on the container 1, the locking lug receivers 10 will interfere with the protrusions 26 because the protrusions 26 would contact a portion of a locking receiver that surrounds the notch 14 instead of extending into the space 18 between adjacent locking receivers. In other words, the position/configuration of the indentions 8 and protrusions 26 preferably prevent the locking assembly 20 from moving to the locked position unless the closure 2 is installed on the container 1 in the correct child resistant position where the locking lugs 9 of the closure 2 are disposed in the notches 14 of the locking receivers 10 of the container 1.
According to embodiments of locking assembly with the protrusions 26, the protrusions also operate to prevent the user from being able to rotate the closure 14 because the protrusions 26 extending into spaces 18 between locking receivers 10 will abut the vertical member 16 of a locking receiver when the closure 2 is rotated, which prevents the locking lugs 26 from being able to disengage from notches 14. It is noted that because both the hooking elements 28 and the protrusions 26 prevent removal of the closure 2 from the container 1, certain embodiments of the disclosure may include protrusions 26 without hooking elements 28 and other embodiments may include hooking elements 28 without protrusions 26.
Referring to FIGS. 6-9, the locking assembly 20 includes a male part 30 and a female part 40 operable to be joined in a sliding tongue-and-groove type connection. In this regard, the male part 30 includes a male engaging member 32 and one of the vertical members 24 with its corresponding hook element 28. The female part 40 includes the other vertical member 24 with its corresponding hook element 28 and a female engaging member 42 dimensioned and configured to interact with the corresponding male engaging member 32 to removably secure the male part 30 to the female part 40 in the locked position. When joined, the male engaging member 32 and female engaging member 42 form the horizontal member 22.
In preferred embodiments, the male part 30 and female part 40 include corresponding components of a positioning assembly for moving the locking assembly 20 between the locked position and the unlocked position. According to the embodiment of FIGS. 6-9, the male engaging member 32 includes a locking tab 34 in the form of at least one set of deflectable wings, and the female engaging member 42 includes a corresponding locking receiver 44 in the form of a passage dimensioned and configured to receive the deflectable wings in their deflected position. To connect the male part 30 to the female part 40, the male engaging member 32 is inserted through the passage 44 until the deflected wings 34 are positioned past the passage 44. Once the wings 34 move past the backend of the passage 34, the wings 34 move to their undeflected position such that the rear ends 36 of one of the sets of wings 34 abut the sidewalls 46 of the passage 44 when a user attempts to extend the locking assembly without deflecting the wings 34, which prevents movement of the locking assembly 20 from the locked position to the unlocked position.
In order to move the locking assembly from the locked position to the unlocked position, the female engaging member 42 includes depressible sidewalls 48 adjacent to the female receiver 44 each having a protrusion 49 disposed on the interior surface of the respective sidewall 48. Thus, when the sidewalls 48 of the female engaging member 42 are pushed together, the protrusions 49 are operable to deflect the deflectable wings 34 of the male engaging member to allow the rear ends 36 of the wings 34 to be deflected and operable to move back through the passage 44. As shown, the male engaging member 32 preferably includes two sets of deflectable wings such that deflection of the first set of wings permits the locking assembly 20 to be moved from its locked position to an unlocked position while the second set of wings prevents the complete removal of the male part 30 from the female part 40.
While the width/circumference of the horizontal member 22 and vertical members 24 are shown in FIGS. 2-9 as being the same, it should be noted that the particular dimensions may vary as desired so long as the locking assembly 20, at least in the locked position, includes a horizontal member that stretches across the top surface of the closure and two vertical members to hook underneath opposing sides of the closure system. In preferred embodiments such as those shown in FIGS. 10-25 described below, the circumference of the vertical members 24 is increased with respect to the horizontal member to make it more difficult to remove the locking assembly 20 from a closure system. In this regard, increasing the circumference of the vertical members makes it not only more difficult to be able to lift the locking assembly 20 in the locked position off a closure system, but it also makes it more difficult slide the locking assembly 20 laterally with respect to the closure system. On the other hand, the desired circumference of the vertical members 24 should take into consideration of the fact that, the greater the circumference of the vertical members 24 (and horizontal member 22), the more resin will be needed to produce the locking assemblies 20.
Referring to FIGS. 10-15, another embodiment of locking assembly 20 is depicted having male part 50 (FIGS. 12-13) and female part 60 (FIGS. 10-11). Similar to the embodiment of FIGS. 1-9, male part 50 includes a vertical member 24 and a male engaging member 52 having a deflectable locking tab 54, and the female part 60 includes vertical member 24 and a female engaging member 62 having a locking receiver 64. However, instead of a set of deflectable wings, the locking tab 54 of this embodiment includes a ramp surface 56 leading to a recess 58 disposed in the top surface of the male engaging member 52. As shown in the cross-sectional view of FIG. 11A, the female engaging member 62 includes a corresponding locking lug 66 secured to top surface of passage 68 leading to the locking receiver 64. In operation, the male engaging member 52 is inserted into passage 68 of the female engaging member 62 until the locking tab 54 traverses the locking lug 66, which secures the locking tab 54 to the locking receiver 64 via the locking lug 66 of the female engaging member being inserted into the recess 58 of the male engaging member 52.
According to this embodiment, the female engaging member 62 further includes an aperture 70 disposed in the top surface of passage 68 adjacent to the locking receiver 64 such that a user is able to deflect the locking tab 54 through the aperture 70 to disengage the locking tab 54 from the locking receiver 64. In certain embodiments where additional security is desired, the aperture 70 may be sized and dimensioned such that a foreign object is required to be inserted into the aperture 70 as opposed to a user's own finger. For example, the aperture 70 may be sufficiently small as shown, which requires the user to use a key 72 having a small protrusion 74 configured to fit into aperture 70 to deflect the locking tab 54. Further, the small size of aperture 70 operates to hide locking tab 54 and locking receiver 64, which makes the manner in which the locking assembly 20 is to be unlocked not easily discernible, especially to young children. As shown, the key 72 preferably includes a key ring 76 such that a user can secure the key to the user's key chain for safe keeping and to easily locate the key 72 when needed. Also, the key 72 preferably includes a recess that houses the protrusion 74 and is sized to closely fit around the top surface of the female part 60. By placing the protrusion 74 in such a recess as shown, the protrusion 74 is protected from being broken off the key 72 and the key 72 provides a self-aligning feature in which the protrusion 74 is inserted into the aperture 70 by positioning the key 72 and associated recess in the correct position over the female part 60.
In preferred embodiments, the key 72 includes indicium instructing the user to keep the key 72 in a location separate from closure assemblies secured with the locking assembly 20 and/or warning the user to not let their children see the user open a closure assembly with the key 72. In certain embodiments, the indicium is molded directly on the key. In other embodiments, the indicium may be provided on a sticker that is adhesively applied to the key 72.
Referring to FIGS. 16-19, another embodiment of locking assembly 20 is provided. According to this embodiment, the locking tab 84 of male part 80 is a single deflectable wing formed by providing spacing 88 between a ramp surface 86 and the male engaging member 82. Upon insertion of the deflectable wing 84 into passage 98 of female part 90, the ramp surface 86 is deflected downward until the deflectable wing 84 engages locking receiver 94. According to this embodiment, the female engaging member 92 includes a depressible top wall portion 96 adjacent the locking receiver 94 such that a user can press down on the top wall portion 96 to disengage the deflectable wing 84 from the locking receiver 94.
Referring to FIGS. 20-23, yet another embodiment of locking assembly 20 is provided. According to this embodiment, male part 100 includes a deflectable locking tab 104 that is positioned slightly above the male engaging member 102 axis in its undeformed position as best shown in FIG. 21. The locking receiver 114 of female part 110 is provided as an aperture disposed in a top surface of the female engaging member 112. In operation, the locking tab 104 is deformed when it is inserted into passage 118 until it reaches locking receiver 114, where it returns to its undeformed position and engages the locking receiver 114 to secure the locking assembly 20 in the locked position. In order to disengage the locking tab 104 from the locking receiver 114, a user manually presses down on the locking tab 104 through the aperture. Thus, this embodiment is similar to the embodiment of FIGS. 10-15 except the aperture 70 of female part 60 has been increased in size and the male engaging member 52 has been configured such that the locking tab 54 engages the aperture 70 in the locked position to allow a user to press down on the locking tab 54 without requiring a key.
Referring to FIGS. 24-25, the locking tab 104 and locking receiver 114 of the embodiment of FIGS. 20-23 can take various forms as desired such as the square configuration of FIGS. 20-23 or the round configuration of FIGS. 24-25.
According to alternate embodiments and referring to FIGS. 26-27, the vertical members 24 of a male part 120 and female part 130 are configured to be connected without requiring a horizontal member 22 to traverse the top surface 4 of the closure 2. For example, and as shown, the circumference of one or both of the vertical members 24 may be increased such that the sides of the vertical member 24 of the male part 120 are operable to be connected to the sides of the vertical member 24 of the female part 130 using engaging mechanisms 122, 132 such as those described above so that the two vertical members 24 form a ring/sheath around the sidewall 6 of the closure 2 in the locked position. In addition to hook elements 28 disposed at the distal end of the vertical members 24 of male part 120 and female part 130, the male 120 and female part 130 each include another hook element 29 disposed at the proximal end of their respective vertical member 24. While the hook elements 29 may take various forms, the hook elements 29 are preferably a lip or perforated tabs extending inward from the vertical member 24. Thus, according to this exemplary embodiment, the ring/sheath formed by connecting the sides of the vertical members 24 is operable to prevent the locking assembly from being lifted off a closure assembly via a first set of hook elements 28 disposed at the distal end of vertical members 24 and a second set of hook elements 29 disposed at the proximal end of vertical members 24. Similar to earlier embodiments, when the second vertical member is connected to the first vertical member and the locking assembly is installed on the closure system in a locked position, hook elements 28 are disposed beneath opposing sides of the sidewall of the closure such that the distal end of the hook elements 28 are disposed adjacent opposing sides of the sidewall of the container. Hook elements 29 are then disposed above at least a portion of opposing sides of the top surface 4 of the closure 2 to prevent the locking assembly from being removed from the closure assembly in the locked position.
Referring to FIGS. 28-29, another embodiment of the locking assembly of FIGS. 26-27 is shown except the engaging members of one side of the respective male and female parts include a hinge assembly 140 to allow the locking assembly to remain connected while moving between the locked and unlocked positions.
In view of the above, it should be understood that the critical components of locking assembly of FIGS. 2-29 are two opposing vertical members 24 having a first set of hook elements disposed adjacent a distal end of each vertical member and another set of hook elements disposed adjacent a proximal end of each vertical member. According to preferred embodiments and as shown in FIGS. 2-25, the second set of hook elements are operable to be connected to each other using corresponding male and female engaging members such that the second set of hook elements form a horizontal member that traverses the top surface of a closure in the locked position. However, in an alternate embodiment as depicted in FIGS. 26-29, the second set of hook elements may extend only partially over the top surface of the closure in the locked position.
According to yet another embodiment of the invention and referring to FIGS. 30-33, a locking assembly is provided that hooks to both the bottom of the container and the top of the closure to lock the locking assembly to a closure assembly. In other words, instead of having hook elements that are disposed underneath opposing sides of a closure as described above, the vertical members extend further down such that the hook elements are disposed beneath the bottom surface of the container. While many versions of this embodiment can be envisioned utilizing the concepts disclosed above with respect to other embodiments that hook underneath opposing sides of a closure, the embodiment shown in FIGS. 30-33 generally includes a male part 150 having a plurality of male engaging members 152 and a female part 160 having a plurality of corresponding female engaging members 162. Similar to the engaging mechanisms described, and particularly the embodiment of FIGS. 10-15, at least one of the male engaging members 152 (and preferably at least two of the male engaging members 152) includes a locking tab 154 operable to releasably engage a corresponding locking receiver 164 of the female engaging member 162. An aperture 166 is then disposed adjacent the locking receiver 164 such that a key protrusion is able to be inserted through the aperture 166 to deflect the locking tab 154 and disengage the locking tab 154 from the locking receiver 164 as described above. As shown, additional male and female engaging members 152, 162 may be provided without locking tabs 154 and locking receivers 164 if desired to provide additional support and make it more difficult to pry the engaging members 152, 162 away from the closure assembly in the locked position. As shown, the hooking elements of this embodiment are in the form of circular discs 158, 168, and the engaging members 152, 162 extend from their respective discs.
In preferred embodiments, the locking assembly is molded out of a stiff resin such as acrylonitrile butadiene styrene (ABS) to further prevent prying open of the device from a closure assembly when in the locked position, A slip additive such as siloxane may also be provided to allow for the male and female parts to easily slide between the locked and unlocked position.
The foregoing description of preferred embodiments for this disclosure has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise form disclosed. In particular, and in view of the numerous potential embodiments of the locking assembly depicted and described herein, it should be understood that the male engaging member and corresponding female engaging member may take various forms within the scope of the present disclosure and obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the disclosure and its practical application, and to thereby enable one of ordinary skill in the art to utilize the disclosure in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the disclosure as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally, and equitably entitled.
