Abstract

The invention relates to a container for receiving contents, in particular liquid foods, having a tubular main body and having at least one molded fiber part connected to the main body, and to a method for producing such a container. For the container to be suitable for being aseptically filled with liquid or paste-like foods, the inner face of the at least one molded fiber part is coated to be gas and liquid tight. The container is produced as follows: pressing at least one molded fiber part from pulp, coating the inner face(s) of the molded fiber part or parts, providing the tubular main body, connecting the main body to the (first) molded fiber part for generating a container that is open on one side, filling the container through the open side, and closing the container by folding or by joining to the (further) molded fiber part.

First claim

The invention claimed is:

1. A container for receiving contents, in particular liquid foodstuffs, comprising a tubular base body and comprising at least one fibrous moulding connected to the base body, wherein the inner side of the at least one fibrous moulding is coated in a gas- and liquid-tight manner by means of a multilayer film which can also contain a barrier layer and wherein the film is guided around the edge of the fibrous moulding in an overlap region in which the film is positioned between an interior surface of the base body and an exterior surface of the fibrous moulding.

2. The container according to claim 1 , wherein the base body is made of packaging laminate.

3. The container according to claim 2 , wherein the packaging at least comprises a layer of board, paper, plastic or aluminum.

4. The container according to claim 1 , wherein the at least one fibrous moulding is made from pulp.

5. The container according to claim 1 , wherein the at least one fibrous moulding forms the upper part of the container.

6. The container according to claim 5 , wherein the upper part of the container has a pouring opening.

7. The container according to claim 6 , wherein the pouring opening is reclosable.

8. The container according to claim 1 , wherein the fibrous moulding is the base part of the container.

9. The container according to claim 1 , wherein the outer side of the at least one fibrous moulding is completely or partially provided with a coating.

10. A method for manufacturing a container including a base body and at least one fibrous moulding, the method comprising the following steps:
pressing at least one fibrous moulding from pulp,
coating the inner sides of each fibrous moulding with a film as far as around the lower edge of the fibrous moulding in an overlap region,
providing a tubular base body,
joining the tubular base body to the fibrous moulding to produce a container open on one side,
filling the container through the open side, and
closing the container by folding or by joining to another fibrous moulding,
wherein the film is coated around the lower edge of the fibrous moulding up to the overlap region in which the film is positioned between an interior surface of the base body and an exterior surface of the fibrous moulding.

11. A method for manufacturing a container including a base body and at least one fibrous moulding having a pouring opening, the method comprising the following steps:
pressing at least one fibrous moulding from pulp,
coating the inner sides of each fibrous moulding with a film as far as around the lower edge of the fibrous moulding in an overlap region,
providing a tubular base body,
joining the tubular base body to the at least one fibrous moulding to produce a container,
filling the container through the pouring opening, and
closing the pouring opening,
wherein the film is coated around the lower edge of the fibrous moulding up to the overlap region in which the film is positioned between an interior surface of the base body and an exterior surface of the fibrous moulding.
