Abstract

For manufacturing a cork stopper (4) with the main body (1) made from cork conglomerate and two end sections in a single piece (S1, S2) made from natural cork and the pores (3) in a direction perpendicular to the axis of the stopper, the following stages are carried out: production of the said main body (1) with the prescribed diameter (D); production of a cylindrical bar made from natural cork (2) with the said diameter (D) and with the pores (3) in a perpendicular direction; cutting of two small circular round slices (R1, R2) from the said bar (2) and adhesive bonding of these onto the ends of the said main body (1) in order to obtain a finished stopper (4). <IMAGE>

Β below such a circular section (S1, S2) on at least one end of the body (1) to obtain the finished plug (4) with the appropriate diameter (D) and height (H1).

The point of the cork plug is that at least one end has at least one one-piece section (S1, S2).

BACKGROUND OF THE INVENTION The present invention relates to a process for making a cork stopper, in particular a stopper whose body consists of a cork conglomerate and. at least one end portion of natural cork with pores perpendicular to the longitudinal axis of the stopper, a new type of cork stopper, valarrin.

In the following, the direction perpendicular to the longitudinal axis of the plug will be referred to as the "perpendicular direction".

The corks from the cork conglomerate have been manufactured to provide high-performance industrial production while providing high-quality corks. However, in these plugs, the liquid in the bottle, such as wine, is contacted not only with the corks but also with its binder.

To overcome this, corks are formed from a cork conglomerate having a natural cork section at least at the end that contacts the liquid in the container. Of course, it is advantageous to have a section of natural cork on both ends of the stopper.

Some of these stoppers have the disadvantage that the pores of the natural cork section are parallel to the stoppers axis and this allows the liquid in the bottle to reach the corks and their binder.

These deficiencies are addressed in U.S. Patent No. 67903 A / 82. an Italian patent for conglomerate cork plugs, the final sections of which are made of natural cork and which are formed by: forming a parallelepipedon-shaped block, the major part of which consists of a cork conglomerate and at least one surface of which is attached to a sheet of natural cork strips; which are glued to each other side and have pores parallel to the sheet. The array is punched perpendicular to the base surface to provide more plugs.

The latter type of plug has the disadvantage that the liquid in the bottle comes into contact with a binder that combines natural cork strips.

To overcome these drawbacks, a method has been devised which produces a conglomerate stopper having at least one end of at least one piece of natural cork having pores which are perpendicular.

According to the present invention, this is achieved by a method of producing a cylindrical body of a cork conglomerate having at least one end a section of natural cork having pores perpendicular to the axis of the stopper and first forming the body of the stopper from the cork conglomerate. providing at least one circular section in the required diameter and height;

from at least one end of the body, at least one such circular section is applied and secured to at least one end of the body.

The circular section may be formed by cutting it from a cylindrical cork rod having a corresponding diameter and pores perpendicular to it, or by punching the section from a natural cork strip having pores parallel to the strip.

An advantage of the present invention is to provide a stopper having at least one end portion of a piece of natural cork having pores which are perpendicular to the body and therefore do not provide passageways for fluid to pass through the body of the conglomerate. It will be understood that at least one end of natural cork is attached to one end of the stopper provided that the stopper can be properly guided before being inserted into the bottle.

DETAILED DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to the drawings, which show an exemplary embodiment of the plug of the invention.

Figure 1 is a perspective view of the parts of which the plug according to the invention is made.

Figure 2 is a perspective view of the parts from which the second embodiment of the plug according to the invention is made.

Figure 3 shows a stopper made by the process of the invention.

Figure 1 shows a body (1) made of a conglomerate having a diameter (D) and a height (H) from which the cork (4) is made, as shown in Figure 3. The cork (4) has a body (1) and end portions (S1, S2) consisting of a piece of natural cork having pores (3) perpendicular to it. From this rod (2) many sections (Sn) can be obtained. Two sections (S1, S2) having a height (h) are cut from the rod (2) and applied to the upper and lower ends of the body (1) and glued to form a finished cork plug (4) having height.

In Figure 2, the body (1) is a flat strip (5) of visible cork of appropriate thickness and pores (3) parallel to the strip itself. From this strip (5), two discs (R1, R2) having the same diameter (D) as the body (D) are cut out, and these discs (R1, R2) are applied and glued to the top of the body (1). and at its lower end to provide the cork plug (4) shown in Figure 3.

Figure 3 shows the finished cork plug. The body (1) of the conglomerate carries two disks (R1, R2) which are glued to both ends. The finished cork plug (4) has a height (HI). .

It is understood that the plug may carry multiple sections or discs at one or both ends.
