Embodiment Construction

[0013] Figure 1 shows the first stage of manufacturing a device according to the invention. The material 14 is plastically deformed so that the raised portion 2a appears. The material 4 of the raised portion 2a becomes thinner than the material 14 outside the raised portion 2a. Thereby its strength is reduced, thus making the material of the raised portion 2a more suitable for the insertion of a drinking straw 20 than the material of the area of ​​the material 14 having a normal thickness.

[0014] Figure 2 shows stage 2 of manufacturing the device. Therein, the material 4 of the raised portion 2b is pressed, forming a folded sealing ring 12 around the hole 6 whereby a thinner material 4 emerges inside the surrounding material 14 .

[0015] Figure 3 shows the device after the drinking straw 20 has been inserted. A rupture area is formed which tightens around the drinking straw 20 and forms a flexible seal 19 . The folded sealing ring is a predetermined circumferential shap...

Abstract

A sealing device ( 2, 2', 2'' ) to be arranged between an opening in a drinking container ( 1', 1'' ) and a drinking straw ( 20 ), and a method of making the sealing device ( 2, 2', 2'' ). The sealing device ( 2, 2', 2'' ) comprises a region of the drinking container ( 1', 1'' ), or a part connected to the drinking container ( 1', 1'' ), made from a material ( 14 ) subjected to a plastic deformation in a portion spanning said opening in the drinking container ( 1', 1'' ). The deformation has the form of a bulge ( 2 a) of thinned material ( 4 ). The bulge ( 2 a) is folded upon itself to form a ring-shaped fold ( 12 ) on the inside of the drinking container ( 1', 1'' ). The fold ( 12 ) encircles the plastically deformed and thinned wall material ( 4 ) of bulge ( 2 a), said bulge material ( 4 ) forming an inner seal ring ( 19 ) around the drinking straw ( 20 ) when the bulge material ( 4 ) is perforated.

Description

technical field [0001] The present invention relates to a device and method for a simple and reliable seal between a beverage container and a drinking straw, eg between a drinking bag and a drinking straw. The method provides an indication of where to insert the drinking straw, reinforcement of the edge of the hole and sufficient weakening of the material in the same area, thereby simplifying the insertion of the drinking straw relative to the prior art. Background technique [0002] Several devices and methods of establishing a connection between a beverage container and a drinking straw are known. However, these devices and methods are not particularly suitable for providing both a physical connection and a proper seal without having to add further material such as plastic, cardboard, metal, glue or the like. Contents of the invention [0003] The object of the present invention is to improve said disadvantages of the prior art. This object is achieved according to the...
