COMPRESSIBLE CONTAINER FOR METERING LIQUID CONTENTS

摘要

The invention provides a container for metering liquid material. The container comprises an interior containing liquid material, a bottom with an endless, upright circumferential wall extending at least substantially in an axial direction of the container from said bottom, and a sealing foil at the upper side of said upright circumferential wall, which retains the liquid material in the container. An outlet can be created in the container for placing the container in an open condition, wherein the circumferential wall is deformable, at least in the open condition of the container, under the influence of an axial pressure force applied to the circumferential wall so as to reduce the volume of the interior of the container for the purpose of emptying the container at least partially in a metered manner via the outlet thus created. The upright circumferential wall extends parallel to the axial direction and/or outward from the bottom to the upper side of the circumferential wall. Seen from the bottom, the upright circumferential wall of the container has at least a first endless wall part and, above said first wall part, a second endless wall part. The first wall part and the second wall part join one another at the location of an endless fold line, which defines a plane extending substantially perpendicularly to the axial direction. Seen in axial sectional view, the first wall part and the second wall part include an angle that faces the interior of the container. The first wall part and the second wall part can be folded about the fold line under the influence of the axial pressure force. The fold line undergoes a radial inward shift under the influence of the axial pressure force during folding and the second endless wall part remains above the fold line.

1. A container for metering liquid material, said container comprising an interior containing liquid material, a bottom with an endless, upright circumferential wall extending at least substantially in an axial direction of the container from said bottom, a sealing foil at the upper side of said upright circumferential wall, which retains the liquid material in the container, in which container an outlet can be created so as place the container in an open condition, wherein the circumferential wall is deformable, at least in said open condition of the container, under the influence of an axial pressure force applied to the circumferential wall so as to reduce the volume of the interior of the container for the purpose of emptying the container at least partially in a metered manner via the outlet thus created, wherein the upright circumferential wall extends parallel to the axial direction and/or outward from the bottom to the upper side of the circumferential wall, wherein, seen from the bottom, the upright circumferential wall of the container has at least a first endless wall part and, above said first wall part, a second endless wall part, wherein the first wall part and the second wall part join one another at the location of an endless fold line, which defines a plane extending substantially perpendicularly to the axial direction, and wherein, seen in axial sectional view, the first wall part and the second wall part include an angle that faces the interior of the container at the location of the fold line, wherein the first wall part and the second wall part can be folded about the fold line under the influence of the axial pressure force, wherein the fold line undergoes a radial inward shift under the influence of the axial pressure force during folding and the second endless wall part remains above the fold line.
