Abstract
A packaging container made of plastic has a fixed wall part (W1), produced by injection molding, and a detachable wall part (W2), which are connected by a predetermined breaking zone (20). The predetermined breaking zone (20) is covered by a barrier layer (24) which provides enhanced barrier action against gases, water vapor or solvent. The barrier layer (24) reduces the permeability of the predetermined breaking zone (20).
Claims31
A packaging container of plastic, comprising a one-pieced container body (11) having a side wall and end wall (14,41), wherein, in the region of said end wall, a fixed wall portion (W1) and a severable wall portion (W2) are provided which are connected to each other by a predetermined weakening zone (20), and
- said predetermined weakening zone (20) is bridged by a barrier layer (24) effective to reduce permeation, said barrier layer (24) being connected to the fixed wall portion (W1) and the severable wall portion (W2).
A packaging container of plastic, comprising a container body having a side wall (11a) and an end wall (14), and
- a predetermined weakening zone (20) is provided, connecting a severable wall portion (W2) to a fixed wall portion (W1) and being bridged by a barrier layer (24) effective to reduce permeation, the fixed wall portion being formed by a neck (15) closed by a cap (17) forming said severable wall portion.
