Description

CLOSURE MUSELET WITH BOTTLE WIRE CONTAINING EFFERVESCENT LIQUID AND METHOD OF MANUFACTURING THE SAME

TECHNICAL FIELD OF THE INVENTION

The invention relates to the field of bottle muselets containing an effervescent liquid, in particular so-called bottles of Champagne.

In this technical field, it is known to stop bottles containing an effervescent liquid by a cork preferably cork, and to hold the cap by a wire generally consists of several metal wires attached as a clamp, taken on the neck of the bottle. In this way, it ensures the tightness of the bottle despite the thrust exerted by the pressure of the gas inside the bottle.

STATE OF THE PRIOR ART

The teachings of the current state of the art offer various bottle caps and bottle capping systems.

Thus, WO 2009/007583 discloses a closure device for bottles of champagne and other effervescent drinks made of wire, made of two parts, namely on the one hand a body or cage having legs and on the other hand a belt that connects the free ends of the legs. This document discloses y-shaped wire made with two wires twisted to form the cage and an additional wire to form the belt. This document mentions a thread but the figures illustrate a cutting of the wire into two wires forming the cage. This type of muelet requires to make several cuts and repositionings son. In addition, the connections between the tabs disclosed in this document exclusively consist of twists.

[0006] DE 254 653 is also known. This document relates to the closure of food packages such as jam bottles. In addition, this document discloses a device comprising a triangle wire and three twisted portions. These two aspects involve on the one hand too much wire consumption to achieve the triangle. On the other hand, a systematic twisting of three legs leads to a significant loss of time. SUMMARY OF THE INVENTION

The invention aims to overcome the disadvantages of the state of the art and in particular to provide a faster manufacturing wire cutter by avoiding a large number of cuts and repositionings of son. To do this is proposed a closing cap for a bottle containing an effervescent liquid, in particular a bottle of Champagne, for clamping a cap on the neck of said bottle, said cap comprising a belt and a cage, the cage comprising three legs that meet at the top forming a "Y". In particular, the wire cap is intended to clamp a cap and a capsule on the neck of said bottle.

In a first aspect, the cage is made by means of a single wire which has a doubled portion which comprises at least one connecting means preferably selected from a twisting and / or welding and / or a loop and / or or a collage and / or a ring. By "wiggle" is meant a winding consisting of at least two turns son. By "loop" is meant a winding consisting of less than two turns of wires. By "ring" means an additional wire for securing said doubled portion of the muzzle.

Preferably, the cage and the belt are made by means of a single wire which has a doubled portion which comprises at least one connecting means preferably selected from a twisting and / or welding and / or a loop and / or a collage and / or a ring. Advantageously, the doubled portion is provided on a leg.

Thus, it produces the wire cap according to the invention with a minimum of cuts and positioning son, thanks to folding a single wire. In addition, this type of muzzle makes it possible to optimize industrialization. The manufacture with a single constituent wire of the muelet is easier, faster and less expensive than with conventional systems. Indeed, in conventional systems it is necessary to cut and position the various son and / or it is necessary to perform a greater number of twists relative to the wire cap according to the invention.

According to an interesting variant, the doubled portion has at least two weld points. According to another variant, the doubled portion comprises at least two distinct zones twisted and / or welded and / or looped and / or glued.

Advantageously, the doubled portion consists of a twisting and / or welding and / or gluing of a tab. Another object of the invention consists in a method of manufacturing a muzzle as described above, comprising the steps for:

(b) - fold the constituent wire of the muzzle so as to form two rectilinear parts of the third leg,

(c) bending the wire to form two portions of the third leg substantially perpendicular to the straight portions,

(d) - folding the wire to form the first leg which comprises a first portion substantially coplanar with the second portion of the third leg and a second portion substantially perpendicular to the first portion,

(e) - folding the wire to form the second leg which comprises a first portion substantially coplanar with the second portion of the third leg and a second portion substantially perpendicular to the first portion,

(f) - setting up at least one connecting means, preferably a twisting, welding, loop, glue or ring at the doubled portion.

By "substantially coplanar parts" is meant elements belonging substantially to the same plane with a distance of up to an angle of about 20 °, depending on the shape of the plug and / or the capsule associated with the muzzle.

DETAILED DESCRIPTION OF AN EMBODIMENT

WO 2009/007583 describes many aspects related to the muselet says "Y" other than those detailed below. The wire used in making the wire cap according to the invention is a standard wire known to those skilled in the art. The thread can be colored for pleasure.

According to the representation of Figure 1, the cap according to a first embodiment of the invention comprises three legs 1,2,3 which form a cage 5, and ends with a belt 4 on which are attached the first and second paws.

The lower end of the third leg 3 is advantageously in continuity with the belt so that the cap is entirely made with a single constituent wire both of the cage 5 and the belt 4. The first tab 1 comprises a first portion 11, and a second portion 12 substantially perpendicular to the first portion at a bend. The first leg 1 ends with a loop 13 for the connection with the belt 4. Different types of terminations of known legs can be adapted to the wire cap according to the invention. The second portion 12 of the first leg is rectilinear, and substantially vertical when the formed muelet is placed on a horizontal support. The first part 11 is substantially horizontal when the formed wire cap is placed on a horizontal support. In particular, the first part 11 follows a radius of curvature of the capsule with which the muster cooperates to form the closure system.

The elbow forms a substantially straight angle that is to say that the first and second parts 11 and 12 form between them an angle of between 90 and 120 °.

The second leg 2 is substantially symmetrical to the first leg with respect to a plane comprising the third leg 3. The second leg therefore comprises first and second parts 21 and 22, and ends with a loop 23.

The third leg 3 has essentially the same shape as the first and second legs 1 and 2. However, the third leg 3 is doubled, that is to say it consists of a double wire, one of which half is in continuity the first leg and the other half is in continuity the second leg.

In this variant, the two halves of the third leg 3 are secured to one another by a connecting means constituted by a twisting 33. According to the representation of FIG. 2, the wire cap according to a second variant generally resembles that of FIG.

In this variant, the two halves of the third leg 3 are secured to one another by two connecting means constituted by two zones of wiggle 33. One of the wiggle zones 33 is located on the second part 31 of the third leg 3 at the junction with the belt 4. The other zone of twisting 33 is located on the second part 32 of the third leg 3 at the junction with the first and second legs 1 and 2 .

According to the representation of Figure 3, the wire cap according to a third variant generally resembles those of Figures 1 and 2. In this embodiment, the two halves of the third leg 3 are secured one with the other by three connection means constituted by three weld points 34. The first weld point 34 is located on the first portion 31 of the third leg 3 at the junction with the first and second legs 1 and 2. The second weld point 34 is located at the elbow of the third leg 3. The third weld point 34 is located on the second portion 32 of the third leg 3 at the junction with the belt 4. Of course, a different number of welding point (s) can be considered. Alternatively, at least one subpart, a portion (31 or 32), or the entire third leg 3 is welded.

According to another variant one or more bonding point (s) may (wind) be considered (s). Alternatively, at least one subpart, a portion (31 or 32), or the entire third leg 3 is glued.

According to the representation of Figure 4, the cap according to a fourth variant generally resembles those of Figures 1 to 3.

In this variant, the two halves of the third leg 3 are secured to one another by two connection means constituted by two loops 35. The two loops are preferably on the second part of the third leg, one being placed after the elbow and the other being disposed at the junction with the belt 4. The loops 35 are substantially a turn of wire.

FIG. 4 illustrates a cap of muzzle 6 cooperating with the muzzle via grooves corresponding to the first portions 11, 21 and 31 of the three tabs 1, 2 and 3. The capsule used is preferably non-metallic, which which makes it easy to make said grooves. This type of capsule is described in the French patent application No. 12 53120 filed April 5, 2012.

Figure 5 schematically illustrates a preferred embodiment of a method for making the wire cap according to the invention. For the sake of clarity, the setting up of the connection means is not represented.

The method preferably begins with a step (a) of folding a constituent wire of the muzzle to form the belt 4. This step is followed by steps (b) to (d) of formation of the cage 5. [ 0044] To form the cage 5, bend (b) the constituent wire of the muzzle so as to form the two straight portions 32,32 'of the tab 3, then we bend (c) the two parts 32,32' to form the elbow of the third leg 3 and then the parts 31 and 31 '. The establishment (step (f) not shown) of the connection means or means between the two son of the portion 32,32 'and / or the portion 31,31' can be carried out from the moment when the two halves of the part in question are formed on the third leg 3.

The double wire of the third leg is then folded into "Y" to form the first and second legs 1 and 2 substantially symmetrical relative to each other. to a plane containing the third leg 3. The first and second legs 1 and 2 are then folded (d and e) to form the bend and preferably the end loops 13.

Alternatively, for the realization of a wire cage whose cage 5 only is made with a single wire, a step (a ') may be provided instead of step (a) to fold the wire on itself and form the second part 32,32 'of the second half of the third leg 3.

The muzzle according to the invention can also be manufactured according to the folds mentioned above but starting with the first leg, then the second (or vice versa) and ending with the third leg. The belt 4 will preferably be made after the third tab 3. This type of method is however less preferred.

The manufacturing method described above can be implemented by an apparatus configured to perform one or more of the various steps mentioned above. Of course, one or more steps can be performed by different devices. An apparatus of the state of the art can for example be adapted to the implementation of the method described above.

Many combinations can be envisaged without departing from the scope of the invention; the skilled person will choose one or the other depending on the economic, ergonomic, dimensional or other constraints that must be respected.
