Seals

摘要

The invention provides a seal that forms part of a container for storing and dispensing consumer products. The container can be used in place of conventional blister packs for the packaging of pills, tablets or capsules or multi-cavity containers for organising and storing mixed medication for subsequent dispensation according to a predefined dosage regimen. The container includes a tray having a generally planar top surface into which has been formed one or more discrete cavities for receiving the consumer products. The seal includes a cover film (1) having a pattern of electrically conductive tracks (14) that defines a circuit per cavity. Pre-formed lines of separation (4) define a removable portion (2) per cavity to retain the consumer products in that cavity until it is removed along its line of separation. Each removable portion (2) is attached to the remainder of the cover film (1) by a frangible bridge region defined by a gap in the associated pre-formed line of separation (4) and which provides a pathway for the associated circuit (22). The frangible bridge region is torn to break the associated circuit (22) when the removable portion (2) is released or removed so that the contents of the underlying cavity can be dispensed.

主权项

1. A seal comprising:
a flexible cover film having a top side and an underside, and a pattern of electrically conductive tracks that are sufficiently flexible so that they are not broken by flexing or bending the cover film, the cover film having pre-formed lines of separation defining one or more removable portion, each removable portion being attached to the remainder of the cover film by a frangible bridge region defined by a gap in a respective one of the pre-formed lines of separation, each gap having a width, the pattern of electrically conductive tracks defining one or more circuits including a respective circuit for each of the removable portions, each respective circuit including an electrically conductive bridge track along the respective frangible bridge region, each bridge track having a width that is wider than the width of the respective gap, and each frangible bridge region proving a pathway for the respective circuit.
