Embodiment Construction

[0015] To avoid burdening this specification with unnecessary details concerning the manner in which blister sheets are used in conjunction with foil backing sheets and cardboard clips, reference should be made to the specification of the parent patent for such details, and the reader should understand that the blister sheet of the present invention Cover sheets are used in a similar manner.

[0016] refer to figure 1 , 2 and 3, these show a part of a transparent, vacuum-formed plastic blister sheet 1 having generally frusto-pyramidal blisters 2 from the One side protrudes. The blister tapers in its protruding direction. A finger breakable airtight backing sheet 4, which may be a thin metal foil, is adhesively sealed to the back of the sheet 1 around the edge of the blister 2 and is used to seal a prescribed dose of medication (not shown) in the Inside the cavity of the blister.

[0017] The blister has a generally rectangular and outwardly projecting front surface 5 with...

Abstract

A blister sheet (1) has a generally rectangular blister (2) formed with one pair of longer side walls (7) having parallel steps (8) and a second pair of shorter side wall (9) devoid of steps. The side walls serve to space a front face (5) of the blister from the plane of a rupturable foil backing sheet (4) which retains medication doses (nor shown) inside the blister until they are to be taken. The medication doses are ejected from the cavity of the blister (2) by depressing its front face with finger pressure so that they are forced against the backing sheet (4) with sufficient force to rupture it. During the application of finger pressure to the front face (5) it bows downwardly in its central region as indicated by the broken outline. Simultaneously the end walls (9) tilt inwardly towards one another so that any medication doses lying against them are forced into the central region of the blister from which they can be ejected more easily by the descending front face (5).

Description

technical field [0001] The present invention relates to a blister of blister sheet material, and more particularly to an improvement or modification of the invention described and claimed in Australian Patent No. 779458 (herein referred to as the "parent patent"), and the present application It is a supplementary patent of the above-mentioned patent. Background technique [0002] The parent patent describes and claims an invention comprising a blister sheet formed with blisters having side walls and a front surface held in contact with the blister by the side walls. Spaced from the back of the sheet, the sidewalls are designed to yield gently while gradually collapsing from the front surface in response to increasing finger pressure applied to the front surface. This enables the elderly to more easily press the front surface of the blister with sufficient force to eject a dose of medication from the cavity of the blister. The force must be sufficient to break the backing s...
