Definitions

  • the invention relates to bottle closures, or bottle stoppers, capable of withstanding the high pressure of carbon dioxide in the beverage contained in the bottle, in particular a highly carbonated beverage such as champagne or sparkling wine.
  • Requirements for sparkling wine market are many and specific, the most important of which are uniformity of performance (sealing, aging, behaviour after opening and retention of organoleptic features), market acceptance (standard appearance of mushroom-shaped type stopper), as well as high quality, corresponding to the price.
  • stoppers especially two-component ones, for closing containers with carbonated liquids, are able to pass carbon dioxide saturation tests using aphrometer, where the upper end wall of the cover is pierced using a needle with sealant to obtain accurate indicators of carbon dioxide saturation while maintaining the necessary tightness of the closed container.
  • a reusable screw cap for champagne bottles is known from the prior art ( EP0079552 , IPC B65D41/04, publ. 25.05.83).
  • the design of said cap comprises a threaded cap housing in the form of a hemisphere and a sealing plug made in the form of a stopper installed in the neck of the bottle.
  • the disadvantage of this design is that when testing for saturation, the presence of the stopper does not allow obtaining the necessary parameters for the concentration of carbon dioxide in the final product, for example, if the aphrometer's needle is not long enough.
  • a stopper for bottles with sparkling wines ( DE3236156 , IPC B65D39/00, publ. 12.11.1987), comprising an outer cap, a sleeve part and a seal in the form of a separate element.
  • the disadvantage of this closure is the impossibility to obtain the necessary parameters of saturation of the product with carbon dioxide due to the presence of a seal that covers the internal cavity of the container, for example, with aphrometers having insufficient needle length.
  • the closest in technical essence to the claimed stopper is a stopper for bottles with champagne and other carbonated liquids, made in the form of a hollow cylinder with sealing rings (sealing part) and a head (outer shell) having a groove along the profile of the bottle finish and a cover, and the entering end of the cylinder has the shape of a hemisphere (A.S. 189699, IPC B67B, 30.11.1966).
  • the disadvantage of this stopper is that the lower end of the sealing part is blind, which does not allow to obtain accurate saturation parameters when using types of aphrometers with a needle of insufficient length, and there is also a risk of carbon dioxide leakage at the place where the stopper is fixed to the cover.
  • the object of the claimed invention is to eliminate the disadvantages of known stoppers for closing bottles with highly carbonated beverages such as champagne or sparkling wine, as well as soft beverages.
  • the technical result provided by the present invention is achieved by creation of a two-component stopper for closing bottles with carbonated liquids, which makes it possible to test the saturation of the final product with carbon dioxide while maintaining the necessary tightness of the closure and without losing the concentration of carbon dioxide in the container when using any types of aphrometers.
  • the bottle stopper comprises a sealing sleeve installed in the neck of the bottle, and an outer shell installed on the sealing sleeve, fixed to each other in axial and radial direction, wherein the outer surface of the outer shell comprises a hole made with the possibility of accommodating the upper end wall of the sealing sleeve.
  • the sealing sleeve and outer shell are made of polymeric materials having different values of elasticity and rigidity.
  • fixing means in the form of axial protrusions and annular groove on the side surface.
  • reciprocal fixing means in the form of vertical locking ribs interacting with the axial protrusions of the sealing sleeve, and an annular collar interacting with the annular groove of the sealing sleeve.
  • the sealing sleeve is provided with annular projections to seal the bottle neck.
  • the stopper for closing bottles comprises a sealing sleeve 1, which is made with annular sealing protrusions 2, upper end wall 3 (see Fig. 2 ) and lower end 4, and outer shell 5, which has a hole 6 on the outer surface 7 and a groove 8 along the profile of the bottle finish.
  • Said hole 6 has a diameter sufficient to accommodate a part of the upper end wall 3 of the sealing sleeve 1, which makes it possible to achieve optimal characteristics of the tightness of the stopper as a whole and the saturation of the carbonated product contained in the bottle with carbon dioxide during the corresponding tests.
  • the outer surface of the upper part of the sealing sleeve 1 comprises axial ribs 9 interacting with the respective vertical locking ribs 10 of the outer shell 5 to fix the stopper's parts in radial direction.
  • Fixing means in the form of upper and lower axial protrusions 11 with an annular groove 12 between them are made on the outer side surface of the sealing sleeve 1.
  • the inner surface of the shell 5 comprises an annular collar 13 located opposite to the groove 12, which, when force is applied, abuts against the upper axial protrusion 11, thus preventing the parts from disengaging when the bottle is opened.
  • the sealing sleeve 1 comprises an annular wall 14 and stiffeners 15, and the outer shell 5 is made with an inner annular protrusion 16, which fits tight against the inner surface of the wall 14 and abuts against the stiffeners 15, thus preventing the annular wall 14 from being compressed under the force of the annular collar 13 when removing the stopper from the neck of the bottle.
  • Said fixing means between the sealing sleeve 1 and the outer shell 5 provide reliable fastening between said parts in axial and radial direction when the stopper is being removed by preventing the outer shell 5 from turning when the stopper is being removed from the neck of the bottle.
  • fixation of the sealing sleeve relative to the outer shell in axial and radial directions is possible using other means.
  • the sealing sleeve 1 and outer shell 5 are made of polymeric materials, and the selected materials may differ in terms of rigidity and elasticity.
  • the sealing sleeve 1 can be made of a softer polymeric material such as low-density polyethylene, etc., because the sealing part must fit the neck of the bottle to ensure a perfect seal
  • the outer shell 4 can be made of a harder polymeric material, such as polyethylene or polycarbonate, because it must firmly fix the stopper on the bottle opening and, therefore, must not give in.
  • the stopper is made of high-quality food-grade polymeric materials resistant to alcohol environments.
  • the described stopper is applicable for closing both alcoholic and non-alcoholic carbonated beverages.
  • the outer shell 5 and sealing sleeve 1 can be made in different colours at the request of the ordering customer.
  • the outer shell 5 may also be made of transparent polymeric material.
  • the parts of the claimed stopper are manufactured by various known methods, in particular, by injection moulding.
  • Assembly of the outer shell 5 and sealing sleeve 1 is carried out by snapping, providing a secure fastening due to the implementation of fixing means in axial and radial directions between the parts.
  • the sealing sleeve 1 When closing the bottle, the sealing sleeve 1 is inserted into the neck of the bottle by axial pressing until its collar abuts against the groove 8 of the outer shell 5.
  • the annular protrusions 2 on the outer surface of the sealing sleeve 1 fit tight against the inner surface of the bottle neck due to gas pressure on the lower end 4, which allows to keep high pressure of carbon dioxide in the beverage and increases the reliability of the sealing of the interior of the bottle.
  • the proposed technical solution allows testing with any type of aphrometers while maintaining the necessary parameters for the tightness of the closure and concentration of carbon dioxide in the final product.
