Device for dispensing from a blister packDevice for dispensing from a blister pack description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090152156, Device for dispensing from a blister pack. Brief Patent Description - Full Patent Description - Patent Application Claims
This invention relates to a pack containing medicinal tablets. The invention relates in particular to packs that comprise one or more pockets into which one or more tablets may be packed. It is known to pack tablets in blister packs made of a plastics material such as polyvinyl chloride (PVC) or polypropylene (PP). Such packs are shaped to have a plurality of pockets into which an individual tablet is contained. The pack is sealed by for example a sheet of foil. When a consumer needs to take a tablet, they simply push the pocket containing the tablet up towards the sheet of foil, forcing the tablet through the foil thereby breaking the seal and releasing the tablet. All other tablets remain in respective pockets that remain sealed. In the terminology used in the packaging art, blister packs of this type are known as primary packaging. In order to enable a consumer to push a tablet through the sheet of foil, the blister pack is made of a highly flexible material, such as PVC or PP. Due to the material properties, the PVC or PP must be thin in order to allow sufficient flexibility and to ensure that the pocket may be sufficiently deformed by a force easily applied by a consumer. Because of the flexibility of the pack, it is necessary to protect the pack from damage whilst at the point of sale and before a consumer has purchased the pack. It is known therefore to pack the blister pack in an outer pack. In the terminology used in the packaging art, such outer packs are known as secondary packaging. The secondary packaging is often in the form of a cardboard box, for example. A problem with existing packs of this type is that the packaging is relatively expensive since both primary and secondary packaging are required. A further problem is that the blister units, and the second packaging if retained, tend to become rather untidy looking in use. Furthermore sometimes tablets pierce the foil sheet inadvertently, for example when in a pocket or handbag. According to a first aspect of the invention there is provided a pack of medicinal tablets, the pack comprising a base wall which defines a plurality of locations for the tablets, wherein at each such location there is a displaceable pocket which constitutes a recess for a tablet, a cover piece of a rupturable material and a tablet between the displaceable pocket and the cover piece, wherein the pack is of a sufficiently rigid construction as to be resistant to permanent deformation. By “medicinal” herein we mean to include vitamin products, other health supplement products and veterinary products. However the tablets are preferably pharmaceutical products (for human health), most preferably analgesics, for example aspirin, paracetamol and ibuprofen. By “tablets” herein we mean to include all individualised solid-form medicinal products, including lozenges. Preferably the pockets are integral with the base wall. Each pocket is preferably upstanding from the rest of the base wall. For convenience the term “pocket” is used herein to denote any displaceable region able to retain a tablet. Preferably each pocket is displaceable from its upstanding position on application of a force by a user, so as to expel a tablet through the cover piece. Suitably each pocket is hinged to the base wall. Preferably the base wall is of a sufficiently rigid construction as to be resistant to permanent deformation. It may advantageously be elastic, such that it can be reversibly flexed. Alternatively or additionally the pack comprises a fame around the base wall and the frame is of a sufficiently rigid construction as to be resistant to permanent deformation. According to a second aspect of the invention there is provided a medicinal tablet pack comprising:
