Fillable cap closure with a film seal that is opened purely by means of rotation or axial pressing

Abstract

The invention relates to a fillable twist cap closure for receiving and film-sealing a liquid or pourable filling in the interior of the closure and for emptying out the filling purely by rotating thetwist cap (1). The closure consist of a receiving part (3) which is screwed onto the threaded connection of a container and which comprises a cylinder (7) that is open at the bottom, said cylinder (7) being film-sealed at the bottom, and a cup (2) that can be introduced headfirst into the cylinder (7). All plastic parts (1-3) are made of a steam-absorbing polymer, and piercing and cutting teeth (5) which extend in the axial direction are molded on the lower edge of the cup (2). Guide means (9, 10, 28) on the outside of the cup (2) interact with guide means (8, 12) on the twist cap (1). When the twist cap (1) is rotated, an axial movement of the cup (2) is first produced in order to pierce the film (33) on the receiving part (3). Upon a further rotation, a purely horizontal rotation is then produced in order to cut open the film (33) along the film circumference by less than 360 degrees. Finally, the cup (2) is moved again axially downwards in order to fold open the cut film (33), whereby the contents of the cup fall downwards.

Description

technical field

[0001] The invention relates to a refillable lid closure, sealed at the bottom with a membrane, wherein the contents are emptied into a container, with which the closure is provided, on the one hand by rotating the lid of the closure or by simply pressing the lid axially. Background technique

[0002] Many beverages today are already produced by mixing concentrates with water. It would be more efficient if the bottling machine could just fill the water locally and add the concentrate to the bottle's water and then mix it only with the initial opening of the bottle by the consumer, rather than dispensing the finished mix. All types of sensitive active ingredients and light-sensitive vitamins can also be metered with the aid of such closures.

[0003] A known solution for metering individual liquids is a plastic metering closure for containers and associated container necks, as pointed out in WO 2012 / 175317 A1. This is a refillable closure, including a button...

Embodiment Construction

[0015] In the first embodiment, the lid closure comprises a total of four parts, in figure 1 Plastic parts 1 , 2 and 3 of these four parts are shown in , in particular in a view in which the three plastic parts are at a distance from each other along their common axis of rotation. The fourth component is a lamination film by means of which the lowest visible edge of the cylinder can be closed.

[0016] Starting from the top, the cap closure here configured as a twist cap closure comprises: a twist cap 1, then a fillable cup 2 below the twist cap and finally at the bottom most a receiving part 3, the cup 2 can Insert the receiving part. When the cup-shaped body 2 is inserted into the containing part 3, the piercing and cutting teeth 5 integrally formed under said cup-shaped body on its edge 4 and protruding downward beyond the edge do not extend all the way into the interior of the containing part 3 The lower edge 6 of the cylinder 7 . This cylinder 7 is connected at the upp...
