Description

This application claims priority from, and the benefit of U.S. provisional patent application Ser. No. 60/988,165, filed Nov. 15, 2007 and entitled Container for Housing Medication, which is incorporated herein by reference.

FIELD OF INVENTION

The present invention generally relates to packaging suitable for storing and dispensing medication and more specifically to containers that house blister cards that provide a simple method for determining whether a dose has been taken while meeting child resistance standards.

BACKGROUND OF THE INVENTION

It is well known that medications, such as pills, tablets, and capsules, must be administered over a dosing period. In many circumstances, the medications can be harmful to children, so law-makers have passed regulations concerning child resistant packaging. The use of child resistant packaging is well known throughout the art, and has been utilized for goods ranging from household items to pharmaceutical products. The pharmaceutical industry has settled on two main methods of dispensing medication, either loosely in a “amber” bottle or more discretely in a blister card.
The traditional child-resistant “amber” bottle utilizes a “push and turn” cap by which the person wishing to open the bottle must press down to release a locking mechanism before turning the cap. These bottles are effective for mass distribution of a medication, but have significant drawbacks. First, “push and turn” cap's are often smaller in size, so that they do not provide a sufficiently stable gripping surface to allow a user of limited dexterity, i.e. the elderly, to access the medication in side easily. Secondly, the level of chemical stability of the individual pills has been a serious concern. Pills that are dispensed in traditional “amber bottles” are often handled and put back into the bottle or, since the bottle is being constantly opened and closed, causing excessive contamination and moisture often enter the bottle. For example, hand moisture and body oils can significantly reduce the shelf-life and effectiveness of a medication. Finally, “amber bottles” provide no compliance feature that informs the user as to whether or not a dose has been taken during that dosing period, be it a morning, afternoon, day, or week.
The other well-known medication packaging is “unit dose” packaging or blister cards. Blister cards are typically formed from flexible materials with a plurality of cavities that receive and dispense one pill. An open side of each cavity is covered with a pierceable foil seal. The user simply pushes a selected pill through the foil seal in order to remove the medication from its individual blister on the card. Blister card packaging ensures stability and allows for patient compliance, although it often does not provide sufficient protection for the medication or child resistance. The pierceable foil seal could be difficult to pierce or remove without damaging the dose, so some blister cards are equipped with a tab the user can pull to remove the foil seal.

SUMMARY OF THE INVENTION

The present invention provides a senior-friendly, child resistant medication dispenser for containing a blister card that includes a permanently locking spine mechanism that secures a blister card inside the container. The container having a two handed press and separate child resistant feature wherein the user must simultaneously press at least two buttons with enough force to bend the buttons as to release them from tabs holding the buttons in a locked position. Once the buttons are depressed with sufficient force as to clear the locking arms the buttons are then separated and the top and bottom of the container are separated about a hinge.
The spine mechanism is integrated into the top of the container and separates the top into multiple sections. The spine uses a hook implement on its inner surface at the peripheral edge farthest from the hinge to snap and lock permanently onto a catch mechanism that is part of the bottom of the container. The catch mechanism is a stiff plastic surface that includes a relatively deep ledge for the hook to bind upon.

Flanges 63 b project upward from the inner upper edges of short walls 62 b. The short walls 62 b and flanges 63 b are formed to identically align with and fit perfectly within latch recesses 55 a of top latch 51 a
As a result of closing top 2 and bottom 20 about hinge 18, lip 54 a makes contact with flanges 63 b forcing the top latch 51 a toward bottom front wall 70. Curved wall 52 a is pressed beneath bottom latch arms 61 b until short walls 62 b and flanges 63 b enter into latch recesses 55 a fitting over lip wall 56 a and within sidewall 57 a. Simultaneously, lip 54 b makes contact with flanges 63 a forcing the bottom latch 51 b toward top front wall 67. Curved wall 52 b is pressed beneath top latch arms 61 a until short walls 62 a and flanges 63 aa enter into latch recesses 5 b fitting over lip wall 56 b and within sidewall 57 b. The combination of top latch 51 a and bottom latch 51 b with top latch arms 61 a and bottom latch arms 61 b create the child-resistance latch system 50 of container 1. A user can release the child-resistant latch system 50 by simultaneously pressing upon the curved surface 52 a of top latch 51 a and curved surface 52 b of bottom latch 51 b. Latch hinges 53 a and 53 b bend allowing top latch 51 a and bottom latch 51 b to lower toward front walls 68 and 69 respectively. Latch recesses 55 a and 55 b release latch arms 61 a and 61 b allowing top latch 51 a and bottom latch 51 b to slide underneath the latch arms 61 a and 61 b.
