Definitions

• the present invention relates to a child-resistant container and more specifically to an easily refillable child-resistant container for storing a removable blister pack having an arrangement of blisters each of which contains a tablet or capsule.
• blister packs are commonly utilized as physician samples for specific drugs and are not always packaged in a child-resistant package/container. The designer of such blister packs is confronted with conflicting requirements.
• the blister pack should be child-resistant and at the same time able to be opened without unreasonable difficulty.
• Typical blister packs are known to be difficult for some adults to open while still failing to be a deterrent for unsupervised children.
• blister packs are often utilized to help users keep track of their daily dosage of medication, which is taken over long periods of time.
• a child-resistant container for storing blister packs provides a second layer of safety. To be effective the container should require a degree of perception and manual dexterity above the abilities of unsupervised children attempting to gain access to the contents of the blister pack and should also be easy for adults to use.
• a container requiring the coordinated use of both hands and the simultaneous application of a force to both a latch and a lock assembly to gain access to the blister pack such as the container of the invention disclosed in U.S. Patent Application No. 10/941,588 filed on September 14, 2004, which was published under U.S. Patent Application Publication No. US 2005/0115862 Al and is incorporated by reference in its entirety herein, provides the requisite level of protection.
• U.S. Patent Application No. 10/941,588 filed on September 14, 2004, which was published under U.S. Patent Application Publication No. US 2005/0115862 Al and is incorporated by reference in its entirety herein, provides the requisite level of protection.
• Patent Application solves the problems mentioned above, several disadvantages still exist in the child-resistant containers. Namely, the manufacturing process requires additional steps to secure the blister pack to the child- resistant container. For instance, holes within the blister pack must be precisely aligned with corresponding holding pins. This step could become time consuming due to the precision required to properly install the blister pack. Other manufacturing processes require that an adhesive be applied to the blister pack to secure the blister pack to the container. The application of an adhesive is not only time consuming but also poses a risk of potentially harmful chemical reactions between the adhesive and the medicine contained within the blister pack.
• blister pack holding child-resistant containers Another disadvantage of currently available blister pack holding child-resistant containers is that the blister packs are not quickly replaceable. In the case of the use of holding pins, a user must detach the old pack and align a new pack with the pins. In the case of the use of adhesives, the user must detach the pack and apply new adhesive for a new pack. Both of these options do not provide for quick replacement of blister packs.

• the application of the inwardly directed force to the flexible member 64 causes an inward displacement of the flexible member 64, which in turn causes the withdrawal of the tang 68 from the notch 66 in the at least one closed side 30 of the housing 18.
