Abstract

THIS CAPSULE IS OF THE TYPE EQUIPPED WITH A CYLINDRICAL SKIRT THE EDGE OF WHICH IS INTENDED TO BE CRIMPED ON THE RING OF THE MOUTH OF A BOTTLE ALREADY EQUIPPED WITH A CLOSING CAP. IT IS PROVIDED, IN SKIRT 2B OF CAPSULE 2, AT THE DESIRED LEVEL OF ITS CUTTING, A PRE-CUT BAND 5 OF AN ANNULAR SHAPE PRESENT ON EACH OTHER OF AN INTERRUPTION 6 OF THE ENDS 5A CONFORMING IN TWO PREHENSION TABS ARRANGED SYMETRICALLY IN RELATION TO THE SAID INTERRUPTION.

Description

248 1,676

  The present invention relates to a capsule of netting, that is to say a capsule njnJ.rd "a cylindrical skirt whose edge is intended to be crimped on the ring of the neck of a bottle already team When a closed bottle is opened, it is customary to remove only the top of the capsule by dressing the skirt, which, if we want clean and clean cutting, requires the use of a

knife.

  The present invention aims to remedy this inconvenience.

  v-deny by allowing. manual removal of the capsule

  while ensuring a perfect cut.

  For this purpose, in the capsule to which it relates, there is provided, in the skirt of the capsule, at the desired level of its cutting, a pre-cut band of annular shape and having on either side of an interruption, shaped ends in two gripping tabs

  arranged symmetrically with respect to said interruption.

  Thus, when opening the bottle,

  simultaneously on the two symmetrical tabs,

  avoids applying torque to the capsule and training

  in rotation, which would not fail to occur

  if there was only one tongue.

  According to a preferred embodiment of the invention,

  tion, each tab has special features such as

  corrugations or other deformations obtained by

  frage, knurling or other. Thus, the tabs have a better coefficient of friction and do not risk

  to escape the fingers of the user. These asperities can

  may be planned along the entire length of the strip.

  Naturally, to further reduce the risk of rotation of the capsule, during the tearing of its belt, it can be provided means for improving the connection and rotation to the neck: dc the boluteille, for example using a coating The inside allows its cementing, or its sealing, or shouting for a large amount of money. In cases where the neck of the bottle has a drain, it is also possible to provide a distortion of the capsule, such as a pin which penetrates into said recess. anyway, the invention will be well understood

  using the following description with reference to the drawing

  attached example showing a non-Im-taSif example, an embodiment of this overcap capsule. Figure 1 pst an elevation before crimping

: on the neck of a bottle.

  Figure 2 is an axial sectional view of the neck

  a bottle equipped with this capsule.

  As shown in the drawing, the capsule 2 according to the invention is of the type having a plane top 2a. permitting its taxation and a cylindrical skirt 2b adapted to be engaged on the neck 3a of a bottle 3 previously closed by a plug 4. The collar 2c that the capsule 2 has the free end of its

  skirt 2b is only intended for distribution facilities

  bution of the capsules in the machines used for their placement on the bottles. This capsule 2 is intended to be crimped on the neck 3a and more particularly below the ring 3b present

this neck 3a.

  To allow its realization with a material

  low cost, such as a sheet of aluminum

  nium, this capsule 2 has in its cylindrical skirt

  2b, a pre-cut band 5 of annular shape and presenting

  as an interruption 6 o o it results the gripping of 0 deu :: cxtrémités 5a in this band 5. As shown

  Figure l. each end 5a is shaped in languet-

  it is detached from the two parts of the cylindrical skirt 2b that '. framing_ We understand aistme: t that, during the tearing of the

  caps-l. 2, at the same time on both languages.

  It is therefore necessary to rotate the capsule 2 on the neck 3a, which would not be the

  case if this capsule presented only one lanlguet-

  the grip and not two tabs arranged symmetrically

  on either side of the interruption 6 of the

band 5.

  With this provision, it is also not necessary to provide a skirt 2b extending well beyond the lower edge of the ring 3b of the neck 3a of

the bottle 3.

  As also shown in Figure 1, to facilitate

  liter the tearing of this capsule by improving the

  holding these tabs 5a between the fingers of the user.

  sateur, each of them is corrugated transversely which, by shortening their length, increases the width of the interruption 6 and further facilitates their grip. It should be noted that these tongues 5a are not protruding with respect to the skirt 2b of the capsule 2 and, consequently, do not disturb the operation of the dispensing machines of the capsules on the bottles As shown in phantom in the figure

  1, with a view to considerably simplifying the

  brication of this capsule, not only the tabs a are provided with asperities such as transverse corrugations but, the whole band 5. Indeed, 9 it is easier to achieve the forming of these asperities

  Savant the cut 5, which can be obtained especially

by knurling or molding. -

  If desired, it is of course possible to improve the rotational connection of the capsule 2 on the neck 3a, for example, by providing an inner liner for its bonding or drying or

  at least having a high coefficient of friction

  in relation to the subject matter of which the said

bonding.

  For the same purpose, one could expect equally

  a recess in the neck 3a, for example a notch of its ring 3b and a deformation of the skirt 2b of the capsule 2 forming a pin likely to penetrate

in the aforementioned recess.

  As is obvious and as is apparent from the foregoing, the invention is not limited to the sole embodiment of this overcap capsule which has been described above by way of non-limiting example; she

  embraces, on the contrary, all the variants of

lisation.
