Definitions

  • the present invention generally relates to an overcap comprising a head and a skirt formed from a heat-shrinkable sheet. It also relates to a container of the bottle type or the like comprising a closed neck and capped with such an overcap. Finally, the present invention relates more particularly to the use of the skirt of an overcap of the aforementioned type to produce such a pouring nozzle.
  • Containers of the bottle type or the like are usually closed by a stopper.
  • the stopper can be inserted into the opening of the neck or alternatively it can cover the neck of the container.
  • the term "cork” or that of "cap” is used interchangeably.
  • a stopper can for example be inserted frictionally into the opening of the neck, be screwed onto the neck or into the opening, be crimped onto the neck, etc. In order to improve the aesthetics of the closure and/or to make the container tamper-proof, it is known to then cover the whole with an overcap.
  • Overcaps of the type mentioned in the preamble above are known. These capsules are formed of a heat-shrinkable cylindrical sleeve, which is closed at one end by a pellet. To put the capsule in place on a bottle or similar container, one begins by capping the neck of the container with the capsule, before heating the latter. The material of which the capsule is made shrinks under the effect of heat, so that the wall of the cylindrical sleeve tightens around the neck. Once the overcap has contracted around the neck, it is no longer possible to remove it without tearing it. Overcaps that have a tear strip are particularly popular because they can be opened without the use of an instrument such as a knife.
  • drip-stop pouring nozzles which are intended to be inserted into the neck of a container of the bottle type or the like.
  • a well-known problem with containers of the bottle or similar type is that, when the container is returned to the vertical position after having poured part of its contents, a drop of liquid is often found suspended at the mouth of the neck. . This drop then tends to run down the outer wall of the container under the effect of gravity, from the mouth towards the bottom of the container. The drip tips are therefore intended to avoid this problem.
  • the document US 5,651,481 in particular, describes a pouring nozzle comprising a drip-stop spout, and which consists of an elastic sheet rolled up on itself so as to form a tube of circular cross-section.
  • the sheet is intended to be inserted into the neck of a container containing a liquid which it is desired to pour without dripping. Due to its elasticity, the rolled sheet exerts centrifugal pressure on the entire inner wall of the neck. This pressure causes sufficient adhesion of the sheet to the inner wall to achieve a tight seal between the inner wall and the sheet. A part of the tube formed by the rolled up sheet protrudes from the neck and constitutes the spout of the spout.
  • a disadvantage of this known spout is that it is normally supplied to the consumer separately from the container and its contents.
  • a consumer has emptied all the contents of a first container and opens a second, it is supposed to keep the spout to transfer it to the second container. It will be understood that this way of proceeding is likely to cause hygiene problems.
  • more prosaically it is not always easy to put your hand back on the spout when you need it again.
  • the document US 5,651,481 consider the possibility of providing the spout with the container and throwing it away after use.
  • the container and the pouring nozzle are sold together, attached to one another, it is necessary either to provide a protective envelope for the elastic sheet; which represents a cost. Either expose yourself to hygiene problems.
  • the overcap comprises a head and a skirt formed from a rolled up sheet, and comprises at least one tear line provided with a tear tape and which delimits a portion of the rolled up sheet which is adapted to serve as a tip pourer on wine bottle.
  • the document further teaches that two things happen when the tear tape is pulled. Firstly, the overcap is completely removed from the bottle so as to provide access to the cork, and secondly, a lower portion of the overcap is detached from the rest of the cap, so that the lower portion is ready to serve as a drip stopper.
  • An object of the present invention is to remedy the aforementioned drawbacks of the prior art by providing an overcap for a bottle of wine, which can be used to produce a drip-stop pouring spout, but with which it is nevertheless possible to serve the wine without having to first remove the capsule skirt.
  • the present invention achieves the above and other objects by providing an overcap according to appended claim 1 and a method according to appended claim 9.
  • the expression “container of the bottle or similar type” designates here a container capable of containing a liquid and which is provided with a neck. It should also be specified that the expression “underneath” (in the claims) refers to a situation where the capsule is oriented with the head upwards.
  • the term “roller” is to be taken in the sense of a cylinder made of a material rolled up on itself.
  • the verb "to tear” is to be taken in the sense of "to cut without using a sharp instrument”.
  • the overcap has the advantageous characteristic of being able to be easily transformed into a pouring nozzle without it being necessary to use an instrument such as a knife to detach the skirt of the overcap from the neck of a container. It will be understood that, thanks to this feature, the invention makes it possible to market together a container and a pouring nozzle that are easy to use, without this significantly altering the usual appearance of the container.
  • one end of the at least one second line of lesser resistance close to the at least one first line of lesser resistance is separated from the latter by a more resistant in-between (zone of resistance to tearing) intended to prevent the tearing of the first ribbon from causing a rupture of the skirt at the level of at least one second line of lesser resistance.
  • the second tear line extends between the bottom of the skirt and the first tear tape following the at least one second line of least resistance, and further passing through the longer in-between resistant, the capsule thus making it possible to detach the head from the skirt without affecting the integrity of the skirt. It will be understood that, thanks to this feature, it is possible to open a container provided with the overcap of the invention, and to pour the liquid, without having to remove the skirt of the cap beforehand.
  • the heat-shrinkable sheet detached from the neck of the container is rolled up on itself, and the roll obtained is introduced axially into the open neck.
  • the elasticity of the sheet must be sufficient for it to press itself against the inner wall of the neck with a force sufficient. This requirement can be problematic.
  • the shape of the neck is imprinted in the material.
  • the heat-shrinkable material adopts and memorizes the shape it has taken under the effect of heat.
  • the skirt of the overcap is removed from the neck to produce a pouring nozzle
  • the plastic sheet removed from the neck of the container will, naturally and without constraint, keep a rolled up configuration.
  • no elasticity opposes the winding of the sheet on itself provided that the diameter of the roll formed is not smaller than the outer diameter of the neck from which the skirt has been removed.
  • the difference between the inside diameter and the outside diameter of the neck of most bottles was sufficient to cause the appearance in the heat-shrinkable sheet of an elastic force of sufficient intensity to ensure the desired seal.
  • the pouring nozzle with which the neck of a particular container is provided preferably comes from the overcap of the same container.
  • the invention is not limited to this preferred scenario. Indeed, the pouring nozzle could also be made from the overcap of a first container and be mounted on a second container. In the latter case, however, it is necessary for the inside diameter of the neck of the second container to be smaller than the outside diameter of the neck of the first container.

  • the head can be made of the same material as the skirt, but it can also be made of an aluminum pellet by example.
  • FIG 1 again shows a first tear tape 7 which goes around the capsule 1 and materializes the limit between the skirt 5 and the head 3 of the capsule.
  • One end of the ribbon 7 is provided to act as a gripping member 9 to allow a consumer to grasp the ribbon to tear it off.
  • FIG 1 also shows a second tear tape 13 which extends longitudinally from the bottom of the skirt substantially to the first tear tape. The lower end of the ribbon 13 is arranged to protrude from the bottom of the skirt 5, so as to act as a gripping member 9.
  • the route of the first tear-off tape 7 defines a circumferential tear line allowing the head 3 to be detached from the skirt 5 of the cap.

  • FIG 2 is a perspective view of a pouring spout obtained from the overcap of the figure 1 , by implementing a particular mode of the process of the invention.
  • the layout of the second ribbon 13 defines a second tear line which is oriented vertically and which extends from the bottom of the skirt 5 to the first tear line. If we find our in the situation where the head 3 of the overcap has already been removed as explained above, it suffices to remove the skirt 5 to tear off the second tear-off tape 13.

  • the overcap is arranged in such a way that it is possible to tear off the first ribbon 7 to open the bottle, without undermining the integrity of the skirt 5.
  • the capsule 1 has a small more resistant in-between (not shown) which is interposed between the first line of least resistance 15 and the upper end of the second line of least resistance 17. Thanks to this characteristic, it is possible to tear off the first strip 7 without causing the skirt to break at the level of the second line of lesser resistance. When you want to completely remove the skirt from the container, just pull on the skirt so as to break the small bridge of material between the lines of lesser resistance 15 and 17.
  • the elastic sheet constituting the skirt 5 has been released from the container, it must be rolled up on itself, taking care that the face of the sheet which was inside the skirt or inside the roll obtained (the roll is referenced 19 on the figure 2 ).
  • the face of the heat-shrinkable plastic sheet which constitutes the inner face of the skirt is protected from external elements (especially dirt), as long as the skirt remains in place around the neck of the container. In these conditions, it is possible to guarantee the cleanliness of the duct of the spout, simply by ensuring that the face of the heat-shrinkable plastic sheet which was protected is indeed that which faces the inside of the spout.
  • the next step is to introduce the roller 19 axially into the neck of the container, while leaving one end of the roller protruding outside the neck.
  • the outside diameter of the roll it is necessary in principle for the outside diameter of the roll to be less than or equal to the inside diameter of the neck.
  • the container it is obviously also necessary for the container to be open, the cap of the container having been previously removed.

  • the spout is then ready to serve as shown in the figure 2 .
  • the end of the roller which protrudes outside the neck constitutes the drip guard spout 21 of the spout.
  • the liquid passes through the cylindrical duct of the spout and escapes through the spout 21.
  • the material from which the sheet is made is preferably a material which is only weakly wetted by most common liquids. Indeed, this characteristic makes it possible to further limit the appearance of drops of liquid suspended from the edge of the spout 21. Those skilled in the art will have no difficulty in choosing a material having this characteristic from the large number of materials available today. today to make heat-shrink overcaps.

Similar to what was the case with the first embodiment, the overcap 101 comprises a head 103 and a skirt 105 which has the shape of a substantially cylindrical tube whose wall is formed of a heat-shrinkable elastic sheet . 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.
