Child-resistant or lockable containers, wherein multiple movements are required to open the container, have many uses. One use for a lockable container is to control the dispensing of medicine and medicaments in the form of pills and tablets. For example, locking caps on medicine bottles are well known. The typical locking cap mechanism requires a coordinated alignment and tipping, or axial pressure, or inward radial squeezing while turning the cap to remove it from its container in order to access the medicaments.
By way of another example, medicines are packaged in convenient flat boxes, which are difficult to secure with child-resistant features. Many medicaments in the form of tablets are sold in blister packs—blisters formed on a sheet sealed by a barrier that is punctured when extracting a tablet from a blister. When a typical cardboard flat box holding one or more blister packs is opened the entire contents of the package is exposed, making all of the tablets immediately available. The dangers posed by children with access to a large quantity of tablets not intended for their consumption is self evident.
The illustrated embodiments of the present disclosure are directed to a child-resistant lockable container for storage and dispensing of medications packaged with a slideable member that holds items, for example, a tray, a drawer with compartments, a blister card, a blister pack, or the like (“slideable card”). The slideable card is illustrated as a conventional blister package, but the slideable member can be a tray, a slideable package, or any other packaging, as is known to those skilled in the art. A lockable container can include a sleeve. The sleeve can be made from any suitable material, including, but not limited to, paper, plastic, metal, cardboard, and the like. A locking assembly is illustrated as a two-piece molded plastic insert that can receive at least a portion of the slideable card. Posts molded on one piece of the locking assembly can be connected, and in some embodiments sealed or welded, with the corresponding hollow cylinders molded on the other piece of locking assembly. Other attachment mechanisms can be used, and use of such other mechanisms is contemplated. The locking assembly can be placed into cooperative alignment with the sleeve, for example, placed inside the sleeve. The slideable card slideably can be translated into at least a portion of the sleeve and the locking assembly.
The locking assembly can include one or more locking features. The locking features can include, for example, one or more posts, apertures, catches, lips, hooks, adhesives, metallic and/or magnetic surfaces, VELCRO® fasteners, or other engaging mechanisms (“post”) formed on one or both of the two pieces of the locking assembly. When the slideable card is inserted into the locking assembly, the engaging mechanisms of the locking assembly can engage, for example, one or more apertures, posts, catches, lips, hooks, adhesives, metallic and/or magnetic surfaces, VELCRO® fasteners, or other receiving mechanisms (“aperture”) formed on or in the slideable card. A release button is located on the locking assembly, and is positioned proximate to the post. One or more ribs, springs, and/or other biasing mechanisms can be located proximate the engaging or receiving mechanisms to exert a compressive force upon, and thereby urge, the engaging mechanism to engage the receiving mechanism.
Pressing the release button manipulates the slideable card to disengage the engaging and receiving mechanisms so that the slideable card can be slideably removed. The sleeve into which the locking assembly can be inserted can include, among other things, a cutout for providing a user access to the release button, an open end, through which the slideable card can be passed, a closed end, and one or more alignment structures for aligning the locking assembly with the sleeve. The sleeve can also include retention mechanisms for maintaining the locking assembly in the proper configuration for the desired operation of the container.
These and further features will be described with reference to the drawings, wherein:
As required, detailed embodiments of the present disclosure are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary examples of the disclosure that may be embodied in various and alternative forms, and combinations thereof. As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as illustrations, specimens, models, or patterns. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials, or methods have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.
For purposes of teaching, the illustrated embodiments are shown and described in the context of a lockable container that includes a sleeve, a locking assembly, and a slideable card that is configured to store and dispense pharmaceutical-related goods. In the illustrated embodiments, the slideable card is illustrated as a blister card. However, the lockable container can be utilized to store and dispense other items, and can be specifically useful for small, delicate, sensitive, or portable items. Examples of such items include all manner of consumable products such as candy, food, vitamins, and the like; and all manner of personal care products such as contact lens, birth control devices, smoking cessation patches, hearing aid batteries, and the like.
Further, the lockable container can be configured to store and dispense items that are not packaged in a blister card but in any slidable platform. In such embodiments, the blister card packaging can be substituted with a tray, card, rack, pack, pouch, or the like. In general, the teaching provided herein are applicable to any structure that holds or stores an item, that provides a basis for attaching or securing an item thereto, or that is otherwise associated with an item. In describing the locking assembly, features and functions are described, though it will be appreciated that the locking assembly may not function as described unless the locking assembly is cooperatively assembled with a sleeve, an outer container, or other package component. Nonetheless, for the sake of brevity and simplicity, the locking assembly functions are described with reference to the locking assembly without illustrating a sleeve or other package component.

According to an exemplary method of forming a blister card 12 blisters 52 are formed in a planar plastic sheet to provide a tray and items are placed in the recesses provided by the blisters 52. Thereafter, a backing, such as a sheet of paperboard or foil, is attached to the planar portion of the tray to enclose the items in the blisters 52. According to this formation of a blister card 12, the planar substrate 50 is defined by laminated layers provided by the plastic sheet and paperboard or foil backing.
The blister card 12 includes an engaging aperture 54 that is dimensioned and positioned to receive the locking post 36. It should be understood, that the shape, location, configuration, and structure of the illustrated aperture 54 is merely an exemplary embodiment of a receiving mechanism. The receiving mechanism 54 can be any element that can cooperatively engage the engaging mechanism 36. In the illustrated embodiment, the aperture 54 is positioned proximate the leading edge E1. The compartment and the blister card 12 are dimensioned with respect to one another such that, when the blister card 12 is substantially, fully inserted into the compartment portion 24, the engaging aperture 54 is positioned or aligned to receive the locking post 36.
The blister card 12 can be alternatively configured and/or formed according to alternative methods. For example the blister card 12 can include an alternative number of blisters 52 and/or blisters 52 that are alternatively arranged. As another example, the blister cards 12 can taper or narrow towards the leading edge E1 to facilitate being received in the sleeve 14. Similarly, although the blisters 52 are illustrated as having substantially the same shape and being spaced apart by substantially similar distances, it should be understood that the blisters 52 can have irregular and/or inconsistent shapes, and that each of the blisters 52 need not contain the same product as the other blisters 52.
A method of operating a lockable container including the locking assembly 10 is now described. In the illustrated embodiment, a locking feature that releasably locks the blister card 12 within locking assembly 10 includes the locking post 36, the biasing elements 48a, 48b, and the engaging aperture 54. To releasably lock the blister card 12 in the sleeve 14, the leading edge E1 of the blister card 12 is inserted through the open end 32 of the locking assembly 10 with the blisters 52 facing the base portion 16.
As the blister card 12 slides into the compartment, the rib 48a can slide between blisters 52, or rows of blisters 52. The blister card 12 can be further translated until the leading edge E1 slides over the sloped surface 38 and the locking post 36 is received in the aperture 54. Thereafter, the contacting surface 39 contacts the edge of the aperture 54 to releasably lock the blister card 12 in the locking assembly 10. Further, the biasing elements 48a, 48b can push the blister card 12 toward the top portion 18 to hold the aperture 54 in a position whereat the aperture 54 is engaged with the locking post 36.
In the illustrated embodiment, a releasing feature for releasing the blister card 12 from the locking assembly 10 includes the release button 40. To release the blister card 12 from the locking assembly 10, the release button 40 is pressed into the compartment portion 24 such that the rib extension 46 contacts the blister card 12 and displaces the blister card 12 toward the base portion 16. The blister card 12 pushes against the biasing elements 48a, 48b and the engaging aperture 54 is lifted out of engagement with the locking post 36. Thereafter, the blister card 12 can be grasped near the trailing edge E2 and pulled away from the compartment portion 24 and through the open end 32. In the illustrated embodiment, the blister card 12 can be prevented from being fully extracted by the retainer 47, which is received in the aperture 54. In alternative embodiments, the blister card 12 can be fully extracted or can be indexed or metered, thereby allowing access to a limited number of blisters 52 at a time.

The sleeve-interface portion 26 of the locking assembly 10 can interact with the flaps 104 and the interface slot 106 to place the locking assembly 10 in the proper orientation for operation of the lockable package 100. In one embodiment, the width of the slot 106 is dimensioned to be substantially equal to the width of the sleeve-interface portion 26 of the locking assembly 10. As such, the edges 114 of the flap(s) 104 can interact with an interface edge 116 of the locking assembly 10 to create a press-fit connection between the sleeve 101 and the locking assembly 10. Additionally, or in the alternative, a portion 118 of the locking assembly 10 can slide under a portion of the flap 104. As such, the portion of the flap 104 that surrounds the interface slot 106 can provide a “shoulder” for the locking assembly 10. The shoulder can add additional support for the locking assembly 10 and can keep the locking assembly 10 being pushed through the open end 102 of the sleeve 101.
The closed-end flaps 108, 110 of the sleeve 101 can be closed to form a closed end 120. The closed end 120 can be configured to provide a snug fit between the locking assembly 10 and the sleeve 101 along the end wall 30 of the locking assembly 10. The closed end 120, the interface slot 106, and the edges 114 can engage the end wall 30, and the interface edges 116 and the interface portion 118 of the locking assembly 10 to hold the locking assembly 10 in a firm and at least substantially immobilized position without the use of adhesives or mechanical fasteners between the locking assembly 10 and the sleeve 101. A slideable card 12 can be inserted into the sleeve 101 and into a locked position by interfacing with the locking assembly 10, as illustrated in
It will be appreciated that the illustrated locking assembly 10 can be made of any desired material, for example, plastic, metal, recycled plastic, and the like. Since the sleeve 101 can conceal most of the locking assembly 10, the color, texture, and other appearance of the locking assembly 10 can be tailored to provide maximum cost efficiency with less attention to appearance of the locking assembly 10. Additionally, the locking assembly 10 can be recyclable, disposable, or reusable since the locking assembly 10 can be held by the sleeve 101 without the use of mechanical or chemical fasteners. In some embodiments, the locking assembly 10 is held in place using chemical and/or mechanical fasteners and container 100 is disposable.
