Abstract

A childproof packaging for individual doses, in particular for preparations for administration in film form, wherein the packaging constitutes a bag produced by sealing, which has a covering layer which is provided at each side of the packaging with local weak points which do not touch the edge of the packaging, wherein the local weak points form a cohesive pattern which runs around the individual dose in an arc or a curve and overlaps an angular region of at least 90° when considered from the main area of the individual zone. The local weak points have a start area and an end area which have a Y configuration when the local weak points on each side of the packaging are superposed.

First claim

What is claimed is:

1. Childproof package including a single dose, in particular for film-shaped administration forms containing active substance, said package comprising a pouch which is produced by sealing, the pouch includes an unsealed area for housing the film-shaped single dose and the package having a top face and an underside face each having a cover layer with a minimum tear resistance of 30 Newtons including on the respective top face and underside face a line of weakness that does not touch an edge of the package, the package includes a sealing seam in surrounding relationship with the unsealed area, each of the lines of weakness form a continuous pattern that extends through the unsealed area in an arc or in a curved path at a predetermined distance from an outer contour of the film-shaped single dose and partially surrounding the film-shaped single dose which lies in a center of the arc or the curved path such that a predetermined portion of each cover layer having the line of weakness remains attached to the sealing seam after opening of the pouch and, viewed from a center of gravity of the film-shaped single dose, covers an angle range of at least 90°, each of the lines of weakness are superposed with respect to one another and each line of weakness includes a start area and an end area operatively positioned in the sealing seam;
the package additionally has, proximate to but separated from at least one of the start area and the end area of each of the lines of weakness, a sidecut, which does not reach as far as an the edge of the package or an edge of the unsealed area of the package prior to opening of the pouch, and the start area and end area of the each of the lines of weakness have a predetermined configuration for forming a tear catcher;
each of the lines of weakness are in the form of a U for exposing three sides of the outer contour of the centered film-shaped single dose in a single-motion during opening of the package while leaving a remaining side of the outer contour of the film-shaped single dose unexposed; and,
the superposed tear catchers of the start areas and the end areas of the lines of weakness form a Y configuration only when the respective lines of weakness are superposed, whereby when a tear initiation is effected by the sidecut, a subsequent catching and guiding of the tear along the arc or the curved path is effected by the superposed Y configuration start and end areas of the lines of weakness.

2. The childproof package of claim 1 , wherein the Y configuration of the superposed tear catcher of the respective start areas and end areas of the lines of weakness includes the line of weakness on the top face has a first branch of the Y configuration at the respective start area and the respective end area and the line of weakness on the underside face has a second branch of the Y configuration at the respective start area and the respective end area.
