Heat-shrink secondary-closure capsule and use of the skirt of a secondary-closure capsule to produce a drip stop spout

a technology of secondary closure and drip stop, which is applied in the field of secondary closure capsules, can solve the problems of hygiene problems, drop of liquid often found hanging from the rim, and it is no longer possible to remove it without tearing, so as to achieve the effect of preserving the integrity of the skirt, facilitating the transformation of the spout, and altering the usual appearance of the container

Benefits of technology

The invention is about a container with a secondary-closure capsule that can be easily transformed into a spout without needing a knife. It is also designed to allow for tearing off the first tear strip to detach the head from the skirt while keeping the skirt intact. This feature makes it convenient to open the container and pour the liquid without needing to remove the capsule's skirt first. Overall, the invention provides a convenient and easy-to-use container with a spout that maintains the appearance of the container.

Problems solved by technology

Once the secondary-closure capsule has contracted around the neck, it is no longer possible to remove it without tearing it.
Indeed, a well-known problem with containers of the bottle type is that, when the container is put back upright after pouring part of its contents, a drop of liquid is often found hanging from the rim surrounding the orifice of the container.
A disadvantage of this known spout is that it is normally supplied to the consumer separately from the container and its contents.
It will be understood that this way of proceeding is likely to cause hygiene problems.
In addition, more prosaically, it is not always easy to get one's hands on the spout when it is needed again.
However, in case where the container and the spout are packaged and sold together, it is necessary to provide a protective envelope for the elastic piece of foil; which has a cost, failing which hygiene problems can crop up.
To the applicant's knowledge, the aforementioned prior solution has never been commercially successful.
This lack of success may be explained by the fact that the secondary-closure capsule proposed in this document is incompatible with certain social prescriptions.

first embodiment

[0037]FIG. 3 is a perspective view of a secondary-closure capsule according to a second particular embodiment of the invention. The secondary-closure capsule 101 is illustrated capping the neck 111 of a container. In a manner similar to that which was the case with the first embodiment, the secondary-closure capsule 101 comprises a head 103 and a skirt 105 which is in the form of a substantially cylindrical tube whose wall is made of a piece of heat-shrink elastic foil. It can be seen that the head of the capsule is arranged to close the upper end of the tube formed by the skirt 105.

[0038]FIG. 3 also shows a first tear strip 107 which surrounds the head 103 of the capsule 101, and also shows a line of least resistance 123 which is arranged to surround the capsule parallel to the tear strip 107, below the latter. The line of least resistance 123 materialises the boundary between the skirt 105 itself and the head 103 of the capsule. In addition, a second tear strip 113 can be seen ext...

second embodiment

[0040]Once the skirt has been opened along the section of the second tear line defined by the tear strip 113, it is possible to just grab both flaps of the skirt and gently pull them in order to detach the skirt by tearing along the line of least resistance 123. It will therefore be understood that in this second embodiment of the secondary-closure capsule, the second tear line is not limited to the section defined by the second tear strip, but also comprises a second section which encircles the capsule. This second section is formed by the line of least resistance 123. It is worthwhile to note that the second section is not directly associated with a tear strip.

[0041]As in the embodiment shown in FIGS. 1 and 2, the embodiment of FIGS. 3 and 4 allows tearing the first tear strip 107 to open the container, without harming the integrity of the skirt 105. However, contrary to what was the case with the first embodiment, the embodiment of FIGS. 3 and 4 also allows reciprocity; that is t...

Abstract

A secondary-closure capsule has a head and a skirt formed from a piece of rolled heat-shrink foil, and it includes a first tear strip that encircles the capsule and is intended for detaching the head from the skirt of the capsule. The capsule also includes a second tear strip that is designed for opening the skirt so that it can be unrolled. The secondary-closure capsule is provided to allow the first tear strip to be torn off so as to detach the head from the skirt without harming the integrity of the skirt.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to a secondary-closure capsule having a head and a skirt formed of a heat-shrink piece of foil. It also relates to a bottle or similar container having a closed neck and capped with such a secondary-closure capsule.[0002]The present invention also relates to an anti-drip spout, which is disposable after use and which is intended to be inserted into the neck of a bottle-type container or the like. Finally, the present invention relates more particularly to the use of the skirt of a secondary-closure capsule of the aforementioned type to produce such an anti-drip spout.PRIOR ART[0003]Containers of the bottle type are usually closed by a stopper. The stopper may be inserted into the opening of the neck or alternatively it can cap the neck of the container. In the presence of the second alternative, the term “stopper” or “capsule” (stopping capsule) is used interchangeably. For example, a stopper may be frictionally ins...
