## Abstract

This invention relates to a child-proof medication package where the medication is arranged between sheets, where an individual accommodation chamber is provided for each drug unit, which is formed by heat-sealing of the sheets and which is accessible from the edge by notch-tearing of the package.

## Claims

### Claim 1

Child-proof medication/drug package in which the medication/drug is arranged between upper and lower sheets, for each medication/drug a special accommodation chamber is provided between the welded or heat-sealed sheets and is accessible by a tearing in of the package proceeding from the edge, comprising two sheets heat-sealed or welded to one another with such a strength and tenacity that they cannot be torn in without a tool at either a lateral edge, nor that the medication/drug can be forced through one of the sheets, and at least one edge there are provided notches, which notches comprise said sheets welded together so that the edges of the sheets are co-terminous in the area of the notch, where at least one such notch is assigned to each accommodation chamber and the tearing force to be mustered while making use of the notch is greater than the force than can as a rule be mustered by a child, and less than a force that cannot as a rule be mustered by an adult.

### Claim 2 (depends on 1)

Package according to claim 1, wherein the notches form jointly a serrated edge.

### Claim 3 (depends on 1, 2)

Package according to claim 1 or 2, wherein the individual notches are formed by two edge portions oriented substantially at right angles to one another.

### Claim 4 (depends on 1)

The invention of claim 1 wherein the lower and upper sheets comprise a lamination of polyamide and polyethylene.

### Claim 5 (depends on 4)

The invention of claim 4 wherein the thickness of the polyamide in the lower sheet is about 40 microns and the thickness of the polyethylene of such sheet is about 75-80 microns.

### Claim 6 (depends on 4)

The invention of claim 4 wherein the thickness of the polyamide of the upper sheet is about 40-60 microns and the thickness of the polyethylene of the upper sheet is about 75-80 microns.
