Abstract

A container comprising a first material and a second material, the first material being a flexible material and the second material being a rigid or semi-rigid material and at least partially defining an interior compartment for keeping a fluid inside the container characterized in that the flexible material and/or the semi-rigid or rigid material have thermoplastic properties and wherein the flexible material and the semi-rigid or rigid material are joined together by a seal or joint which comprises a heat seal and an adhesive seal.

First claim

The invention claimed is:

1. A container, comprising a first material, and a second material,
wherein the first material is a flexible material, and the second material is a rigid or semi-rigid material and the first material at least partially defining an interior compartment for keeping a fluid inside the container,
wherein the flexible material and/or the rigid or semi-rigid material have thermoplastic properties, and
wherein the rigid or semi-rigid material comprises a rabbet trench into which the flexible material is arranged such that a heat seal located on the side facing an interior of the container is in-between and connects the first material and the second material and an adhesive seal located on a side facing exterior of the container such that the adhesive seal is in-between and connects the first material and the second material.

2. The container according to claim 1 , wherein the flexible material is a laminate film.

3. The container according to claim 2 , wherein the flexible material is comprised of two or more material layers of different thermoplastic materials and the thermoplastic materials have different melting points.

4. The container according to claim 2 , wherein the laminate film comprises at least two plastic material layers which layers are of different plastic materials relative to each other.

5. The container according to claim 3 , wherein the thermoplastic facing the interior of the container has a lower melting point than the side facing outwards.

6. The container according to claim 1 , wherein the rigid or semi-rigid material is used as a platform for sensor coupling or tube coupling.

7. The container according to claim 1 , wherein the rigid or semi-rigid material forms a reinforcement portion for the container.

8. The container according to claim 7 , wherein the reinforcement portion is formed of a bottom and/or a top of the container.

9. A method of providing the seal between the flexible material and the rigid or semi-rigid material in the container of claim 1 , the method comprising: providing a trench in the rigid or semi-rigid thermoplastic material edge portion of the flexible material;
providing an adhesive on the flexible material; inserting the flexible material into the trench; solidifying the adhesive; and
heat-sealing the side opposite to the side of the flexible material comprising the adhesive.

10. The method according to claim 9 , wherein the heat-seal is provided by hot-air or hot-mold seal.
