Definitions

  • the present invention relates to the field of caps, in particular to the field of caps for bottle and preferably screw-type caps for bottle.
  • the present invention concerns a cap for bottle, preferably of the screw type, in which a head and a cylindrical element inside the head constitute two parts, which are mutually stably assembled to form a single piece.
  • the screw-type caps for bottle also called screw caps for bottle
  • the caps are made of metallic materials.
  • the upper inner surface of the cylindrical cavity of the head is coated with a layer of partially soft material, typically consisting of expanded plastic material, which interposing between the edge of the neck of the bottle and the lower surface of the cavity of the screw cap, allows to achieve and improve the tightness.
  • a layer of partially soft material typically consisting of expanded plastic material, which interposing between the edge of the neck of the bottle and the lower surface of the cavity of the screw cap, allows to achieve and improve the tightness.
  • this is typically made of metallic material.
  • screw caps thus made of wood.
  • the realization of screw caps in wood imposes the need to employ a cylindrical element in plastic material that, interposing between the liquid and the wood of the head, allows to prevent the wood from getting soaked with liquid.
  • the main drawback is the detachment of the wooden head from the cylindrical element that remains tightened on the neck of the bottle.
  • the screw caps available today are made of metallic materials or of plastic materials. Therefore, a further problem is that of making easily biodegradable caps.
  • the problem addressed by the present invention is therefore that of providing a cap for bottle able of allowing the good tightness of the liquid contained in the bottle, of being in a such a way as to guarantee the non-detachment of the head of the inner cylindrical element and, preferably, of being, at least partially, biodegradable, allowing to solve the aforementioned problems, with particular attention to the problem of keeping the various parts of the cap firm.
  • the invention relates to a cap for bottle that, by means of the particular conformation and combination of the pieces that compose it, allows making a cap for bottle in which the head is firmly assembled to the inner cylindrical element, at the same time allowing the at least partial biodegradability of the cap.
  • Fig. 1 shows a perspective view partially from above of the partially exploded cap according to an embodiment of the invention
  • Fig. 2 shows a perspective view partially from below of the exploded cap, according to an embodiment of the invention
  • Fig. 3 shows a bottom view of the cap, according to an embodiment
  • Fig. 4 shows a sectional view of the cap of Fig. 3.
  • a cap for a bottle (not shown in the figures) provided with neck 15 is indicated with 1, in accordance with the present invention.
  • the cap 1 comprises a cylindrical head 2 having an axis X-X.
  • the cylindrical head 2 has a first cylindrical cavity 4 coaxial with the axis X-X of the cylindrical head 2.
  • the first cylindrical cavity 4 is open at the bottom and closed at the top by a first circular surface 5.
  • the first cylindrical cavity 4 has an annular channel 6 coaxial with the axis X-X and attached with the first circular surface 5.
  • the cap 1 further comprises a cylindrical element 3 adapted to be housed inside the first cylindrical cavity 4.
  • the cylindrical element 3 has a second cylindrical cavity 7 coaxial with the axis X-X.
  • the second cylindrical cavity 7 is open at the bottom and closed at the top by a second circular surface 8.
  • the second circular surface 8 has at least one hole 9.
  • the second cylindrical cavity 7 has an inner side surface 7a configured to engage removably with an end part of the neck 15 of the bottle.
  • the inner side surface 7a of the second cylindrical cavity 7 comprises threads 10 configured to engage removably with threads 16 formed on the end part of the neck 15 of the bottle.
  • the cap 1 further comprises a layer of plastic material 11 adapted to fill the annular channel 6 and to form a circular layer 12 that covers at the bottom, preferably entirely, the second circular surface 8.
  • the annular channel 6 may have a diameter comprised between 101% and 120% with respect to the diameter of the first cylindrical cavity 4, preferably between 105% and 115%.
  • the annular channel 6 may have a cross-section of rectangular or semi-circular shape, preferably having a rectangular cross-section.
  • the annular channel 6 is attached to the first circular surface 5, i.e. the edge of the annular channel 6 is attached to, i.e. merged with the first circular surface 5.
  • the term attached means that part of the annular channel 6 consists, on the one hand, of the first circular surface 5.
  • the annular channel 6 has a rectangular-shaped cross-section and consists, on the one hand, of the first circular surface 5.
  • the first circular surface 5 of the head 2 is partially covered by a circular protrusion 13.
  • Said circular protrusion 13 has the function of keeping the cylindrical element 3 partially detached from the first circular surface 5 so as to realize, according to one embodiment, a space for the passage of the molten plastic material so that it reaches the annular channel 6.
  • an upper part of the second circular surface 8 of the cylindrical element 3 has at least one groove 14 extending between the hole 9 and the outer perimeter of the cylindrical element 3.
  • Said groove 14, according to one embodiment, allows the passage of the molten plastic material, entered from the hole 9, so that it reaches the annular channel 6.
  • the groove 14 has a rectangular-shaped cross-section. According to one embodiment, the groove 14 is tapered with taper increasing from the hole 9 to the outer perimeter of the cylindrical element 3. In other words, the gap of the groove 14 increases from the hole 9 to the outer perimeter of the cylindrical element 3.
  • the number of grooves 14 is the same as the number of holes 9.
  • the cylindrical element 3 has at least one hole 9 that allows the passage of the molten injected plastic material so that it fills the annular channel 6 that guarantees the tightness between the two parts, cylindrical element 3 and head 2.
  • the cylindrical element comprises from 5 to 20 holes, more preferably from 5 to 10 holes, even more preferably it comprises 6 holes.
  • the head 2 is made of wood or similar material, such as cork, another biodegradable material of natural origin.
  • the cylindrical element 3 is made of plastic material, preferably of rigid plastic material. Traditional plastic or composite plastic material is typically used.
  • the head 2 is made of wood or similar material and the cylindrical element 3 is made of plastic material.
  • the circular layer 12 that covers the entire lower part of the circular surface 8 of the cylindrical element 3 also performs the function of seal.
  • Another object is the process for making the cap 1 as described above.
  • the process comprises the following steps: a) inserting the cylindrical element 3 inside the first cylindrical cavity 4 of the head 2, b) injecting molten plastic material so as to form, after cooling, a layer of plastic material 11 adapted to fill the annular channel 6 and to form a circular layer 12 that covers at the bottom the second circular surface 8 of the cylindrical element 3.
  • the cap for bottle 1 described above can be used to close bottles of wine, of super alcohols, of perfumes and of cosmetic products, such as creams, lotions, oils, etc.

Abstract

La présente invention concerne un bouchon (1) pour bouteille, dans lequel la combinaison entre la tête (2), un élément cylindrique interne (3) et une couche de matériau plastique (11) qui, en remplissant un canal annulaire (6) de la tête et en recouvrant la surface inférieure de l'élément cylindrique, (3) permet d'éviter le détachement de la tête de l'élément cylindrique interne, permettant ainsi d'obtenir des bouchons robustes pour bouteilles ayant, par exemple, la tête en bois et l'élément cylindrique interne en plastique.
