Embodiment Construction

[0016] In order to further illustrate the function and use of the present invention, exemplary applications will be described in the detailed description of various embodiments.

[0017] figure 1 is a cross-sectional view of the opening device 100 according to the first embodiment of the present invention. The membrane member 102 extends from the underside of the support member 104 and has a protrusion 106 extending into an opening 108 of the support member. In the opening, the support member 104 has an undercut design so that the membrane member 102 is held in place. The opening 108 may have a substantially conical shape such that the protrusion 106 cannot be pulled out of the opening. The skilled artisan will recognize that the opening 108 can have a variety of designs, some of which are in figure 1 As shown in , one way of representing the opening may be that the protrusion 106 includes a portion having a diameter that is greater than the diameter of at least a portion o...

Abstract

An opening device (100) for a packaging container (112) comprises two operational parts: a membrane part (102) ensuring a secure seal of the packaging container and a support part (104) ensuring rigidity for the opening device. The opening device is characterized in that a membrane portion of the membrane part is mechanically attached to the support part to operate as one piece during opening of the packaging container, and the materials of the membrane part and the support part are thermally incompatible.

Description

technical field [0001] The present invention relates to an opening device and a manufacturing method of the opening device. The invention also relates to a packaging container having such an opening device. Background technique [0002] Packaging containers intended for consumer use are provided with some sort of opening device. Some preferred features of the opening device are that it should be easy to actuate and provide an adequate and reliable seal for the product contained in the packaging container. The definition of an adequate seal varies depending on the type of product contained in the packaging container and the manner in which the packaging container is stored, among other things. A common requirement is that before the opening device is opened for the first time, the opening device should prevent external microorganisms from reaching the product, since this would rapidly deteriorate the quality of the product. In some cases, it is also desirable to prevent ce...
