Push and peel pack for dispensing medicants

Abstract

A push and peel child resistant and senior friendly tamper evident package comprising a blister sheet with U cuts for pushing an outer layer of interior tabs, the blister sheet having blister pockets projecting from a front side thereof, a rupturable foil layer being adhered to the blister layer and reinforcing the paperboard material adhered to the foil layer, an inner data layer with diecut oval holes, the paperboard layer having a tear strip formed therein, the tear strip being defined by a cut into the paperboard layer from the side thereof adhered to the foil layer, the cut extending only a certain percentage of the total thickness of the paperboard such that a controlled delamination of the paperboard layer occurs when the tear strip is removed. This provides a precise reinforcement of the foil layer.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a tamper evident, senior friendly and child resistant package of the type operable by means of a combination punch out of the inner card hole or push on the existing hole to release the lead area of the tab on the outer layer and with a full delamination feature tear strip for unsupported foil and a periphery delamination feature for paper.BACKGROUND OF THE INVENTION[0002]Blister packs are well known in the art and are widely used to package individual items such as different forms of medication including tablets, capsules and the like. In addition, the packaging of a small amount of liquid in an individual blister is known.[0003]Usually, the item or product is accessed through the rear of the blister pack which is provided with a tear strip.[0004]As aforementioned, there are three different properties which any packaging ideally possesses. The first is that the package should be tamper evident such that there will be prov...

AI Technical Summary

Benefits of technology

[0008]It is an object of the present invention to provide blister pack packaging which is tamper evident, senior friendly, child resistant and capable of adding electronic circuitry.

[0009]It is a further object of the present invention to provide blister pack packaging which is easy to manufacture and overcomes some of the deficiencies of the prior art packaging.

[0013]In a further embodiment of the present invention, the tear strip may be defined by a partial cut through a portion of the paperboard. In this embodiment, the paperboard would be adhered to the foil layer and once the tab is pulled, a controlled delamination of the paperboard within the tear strip will occur. This will leave a portion of the paperboard still adhered to the foil to provide a further reinforcement and add effectiveness in its ability to prevent children from accessing the product.

[0014]After removal of the paperboard material, the foil may be removed by pushing the foil in the area of the depression formed in the blister layer. This prevents removal of the foil with less effort than would otherwise be the case.

[0022]In the above described embodiment, there is also provided a line of weakening which is cut into the paperboard from the inner side thereof at the position where the capsule will be ejected from the blister pocket. This line of weakening assists in dispensing of the product and may extend into the paperboard for a distance of between 60 and 80% of the thickness thereof depending on the product to be dispensed. Note the shape of the line of weakening can be changed to suit the product. Thus, the shape of the line weakening or diecut could either be straight or oval in the precise form of the tablet or pill. The amount of cutting and the configuration can control the effort required to access the product.

Problems solved by technology

While such a package is inherently tamper evident unless the whole foil layer is replaced, it is not very child resistant and indeed can prove attractive to some children.

When electronic circuitry is bent, the circuitry can break and render the circuitry useless.
