Blister Pack With Opener

Abstract

A blister pack with opener of a bonded or welded sheet-sheet design having a transparent top layer with blister, an adhesive layer or welded perimeter, a means for displaying the blister pack, a means for gripping the blister pack and a means for opening the blister pack. (Optional—a means for allowing the inclusion of additional information about the product and a means for detecting the opening of the product)The design of the blister pack assembly FIG. 1 includes a backplane 13, a blister layer 14, an adhesive layer 20 to permanently affix the backplane to the blister layer, a counter-pull ring 5 to allow the user to control the pack while opening, a tear wire pull ring 8 attached to the first end of a tear wire 7 to allow the user to apply a tensile force sufficient to cause the tear wire to cut through the pack, a tear wire channel 10 to house the tear wire 7, a means for weakening the tear wire channel so that the tear wire may be deployed without undo force. This means may be perforation 12, a thinning of the material that forms the roof of the channel, or a change of material along the tear wire path such as aluminum foil or a similar substitute. Said assembly includes a deformation 11 in the blister layer to allow sufficient space to enclose the intended product, an anchor 17 to permanently affix the second end of the tear wire to the backplane 13, a joint 6 to allow the attachment of the tear wire ring 8 to the tear wire 7 and a joint 16 to allow the attachment of the tear wire 7 to the tear wire anchor 17, a removable service disk 9 temporarily attached to the inside perimeter of the pull ring 8 and containing an aperture 15 for product display

CROSS REFERENCE TO RELATED APPLICATIONS[0001]NoneFEDERALLY SPONSORED RESEARCH[0002]Not ApplicableSEQUENCE LISTING[0003]Not ApplicableBACKGROUND OF THE INVENTION[0004]1. Field of the Invention[0005]The Blister pack with opener relates to the means for separating a standard generic retail blister pack into two halves for easy access to the product(s) therein.[0006]2. Prior Art[0007]Every year millions of products are sold in plastic blister packs that essentially form a clear hard transparent shell over the product. They are popular with manufacturers as they are inexpensive, accommodate any shape product, protect the product from dirt and moisture and are see-through allowing the customer to see exactly what they are buying. However, they have one serious drawback—they are difficult and potentially dangerous to open. Nearly always, some kind of tool is required; either a knife, scissors, razor.

AI Technical Summary

Benefits of technology

"The Blister pack with opener is a unique and novel invention that provides a built-in way to open a blister pack. It has several advantages, including being easy to open, requiring no additional tools, and being one-time use to prevent unauthorized substances from being added. The pack also has a tear wire channel that is well-defined and pre-conditioned to separate in a specific way, making it easy to open. Additionally, the pack has a counter pull finger hole and a means for pulling the tear wire from the pack. Once opened, the pack cannot be reused. This invention provides a convenient and secure way to open blister packs."

Problems solved by technology

However, they have one serious drawback—they are difficult and potentially dangerous to open.

When using a knife or razor considerable force must be exerted to force the blade through the pack and steer it along the edge which is downward dangerous as it provides the possibility of a severe cut to the hands.
