INVIOLABLE AND IRRELLENABLE COVER WITH OVERHEAD

The stopper is provided with a mechanism, of the non-refillable type, formed by a landfill, a valve and a gasket or valve seat that allows the liquid to escape, but not the inlet thereof.

A tube forms a single piece with the non-refillable mechanism, when the tube is attached to the base of the landfill by ultrasonic welding or glue. The tube has formed on the inner cylindrical surface, a series of angled anchors, which are housed in a waist that has the neck of the bottle and does not allow the cap to be removed, once placed in the bottle. On the inner cylindrical surface of the tube, a series of vertical ribs have been provided that prevent the tube from rotating when placed in the bottle, as opposed to vertical drops that the neck of the bottle has.

The present invention constitutes an improvement to bottle caps such as those mentioned in Mexican patents Nos. 156456, 165266, 171075 and 176414.

Field of the Invention The present invention relates to bottle caps or containers containing liquids, such as alcoholic beverages, which require a lid of the inviolable type and a non-refillable type mechanism that allows the liquid to flow out of the interior of the bottle, more not so the entrance of the liquid to the bottle. BACKGROUND OF THE INVENTION There are several designs of inviolable or non-refillable caps on the market or with these two characteristics combined, which have some flaws, which causes them not to meet the need, every day more important, to protect the contents of the bottles and guarantee to the consumer that the bottle has not been refilled or the original liquid content has been adulterated.

The object of the invention is to overcome these failures and to provide the bottler with a cap that meets the requirements of having an inviolable screw cap, in combination with an irreplaceable mechanism.

The design of the screw cap guarantees that, once the cover is screwed into the landfill, it cannot be unscrewed without the lower ring being detached and the latter broken into two parts, making it evident that the cover was previously unscrewed and because of having an overcap which can be of different color to the lid to make the lack of the ring more noticeable.

To ensure a tight seal, a central rod has been placed inside the lid that presses the valve against the seat, making a first closure and a skirt or vertical cylindrical surface that peripherally presses the outlet hole of the landfill liquid, making a Second closure

To prevent the cap from being removed from the neck of the bottle, it is used to mold the tube, a thermoplastic resin high heat resistance, such as ABS (acrylonitrile-butadiene-eεtirene) or polycarbonate.

Description of the Invention The present invention relates to a particular design of caps for liquids, of the inviolable and non-refillable type whose irrellenability characteristic is achieved by a mechanism consisting of a gasket or valve seat, a valve and a landfill. This mechanism allows the liquid to escape from the bottle and prevents entry into said bottle.

By pouring the liquid, the valve separates from the seat and when trying to refill the bottle, the valve blocks access to the inside of the bottle. To prevent the valve from adhering to the seat, a vertical rod has been placed inside the lid that ends at a crosshead that is inserted into an angled vertical valve cavity that rotates the valve, by unscrewing the cap.

A tube that forms the outer surface of the cap, is manufactured with high-strength and flexible flexible terrestrial resins, in order to avoid that the cap can be removed from the neck of the bottle and can be refilled, placing the cap on Your original position. The tube has a series of angled anchors in its upper part, which allow it to slide over the neck of the bottle and that are housed in a waist of the bottle, which prevents the cap from being removed once it has been removed. placed on the neck of the bottle. The tube also has on its inner surface, a series of vertical nerves that when opposed to a few drops that has the neck of the bottle, prevent the cap from rotating when placed in the bottle. The landfill is attached to the upper inner surface of the tube when both parts are welded by ultrasound or by some glue, which firmly fixes the non-refillable mechanism to the tube.

To achieve a tight seal, it has been provided inside the lid, with a vertical rod finished in the form of a crosshead that presses the valve against the seat and at the same time rotates the valve when unscrewing the lid by inserting the crosshead into a angled valve cavity. A second closure is made by means of a vertical cylindrical surface of the lid that makes intimate contact with the exterior vertical wall of the landfill where the liquid inside the bottle comes out, blocking this outlet.

The screw cap has a ring on its lower outer surface adhered to the body of the lid, by means of small ribs or bridges, which are broken by unscrewing the lid for the first time, because the ring has a series of angled teeth in its inner surface that allows the cover to be screwed and prevent the ring from rotating when the cover is unscrewed, as opposed to a series of angled teeth that the landfill has, at the height of the cover ring.

The vertical cylindrical body of the lid is smaller in diameter than the ring in order to place an overcap of the same diameter of the ring with the possibility, that when molded the cover of a color different from the overcap, the ring becomes more noticeable and when it comes off the cover the lack of the ring becomes more obvious.

The set of teeth of the ring and the landfill because they are angled allow the cover to be screwed to the landfill, but they prevent turning the ring when unscrewing the cover by opposing the angles of the teeth, which causes the small nerves or bridges to fracture as they continue turning The body of the lid. In this way the inviolability characteristic of the cap is achieved.

The landfill has in its interior, a concentric tube that aims to guide the valve in its movement on the vertical axis of the plug, when the liquid is poured. The dump has formed on the outer cylindrical surface, a rope with two entrances where the lid is screwed.

The gasket or valve seat has in its upper part, a cylinder with rings on its vertical outer surface that embed on the lower cylindrical surface of the landfill and make a tight seal. On the lower cylindrical surface of the gasket or valve seat, a series of rings have been placed that make a tight seal, when the cap is fixed, with the inside of the neck of the bottle.

The central part of the valve seat has a vertical rod that enters a cavity that has the valve in its lower part and which is intended to guide the valve in its movement on the vertical axis of the plug. The packing or The valve seat also has a horizontal ring in the central part that serves as a seat to the valve and makes a tight seal when the valve is pressed by the plug stem, preventing the passage of liquid through the central cavity of the gasket or valve seat .

The novelty, as well as the unique characteristics of this invention and its operation, will be better understood by referring to the description of the pieces, by means of the attached drawings in which:

Referring to Figure 1, it shows the "A" overcap; the cover "B"; the landfill "C"; the "D" valve; the gasket or valve seat "E"; the tube "F" and the neck of the bottle or container "G".

In figure 2, the overlay "A" is shown which has a vertical wall 1 that can have a series of grooves 2 in order to better hold the overlay "A". Inside the vertical wall 1, a series of vertical segments 3 have been placed, ending at angles 4 that are housed between the vertical segments 12 (see Figure 3), placed on the upper outer wall 14 of the screw cap. "B". These vertical segments 12 also end at an angle 9 in order to facilitate the assembly of the overlay "A" to the cover "B". The purpose of these vertical segments 3 and 12 is to attach the cover "A" to the cover "B" so that both parts rotate together. The lower part of the vertical cylinder 1 of the overcap "A" ends in a horizontal ring 6 which has on its inner face a series of cords 5 embedding between another series of cords 17 having the vertical cylindrical surface 14 in order to assemble the Overlay "A" to cover "B" and avoid separating both parts. The horizontal lower cylindrical surface 7 of the cover "A" makes contact with the upper cylindrical surface of the ring 20 of the cover "B".

The vertical cylindrical surface 14 of the cover "B" has formed inside a helical rope with two entrances 18, which thread on the rope 30 of the landfill "C" in figure 4.

As can be seen in Figure 3 of the horizontal surface 8 of the cover "B", the vertical rod 13 is projected which ends in the form of a crosshead 16 and which is intended to press the valve "D" on the horizontal circular surface 38 and at the same time the valve blocks the hole 53 of the gasket or valve seat "E" (see Figure 6) when the angled surfaces 41 and 42 of the valve "D" are in contact with the horizontal circular ring 47 of the gasket or seat of valve "E". The crosshead 16 of the stem 13 is inserted into the upper cavity 37 of the valve "D" and is intended to rotate the valve "D by turning the cover" B ", because the vertical wall 39 of the cavity 37 is slightly angled so that the crosshead 16 having a larger diameter makes contact with the vertical wall 39 of the valve "D." When the cover "B" is threaded to the landfill "C", the horizontal circular surface 15 of the rod 13, press the valve "D" on the horizontal circular surface 38 so that the valve "D" blocks the circular hole 53 of the gasket or valve seat "E".

A second closure is achieved by means of the cylinder 10 of the lid "B" which has a cord 11 that is inserted into the cavity 25 of the landfill "C" and makes a tight seal when the cord 11 of the lid "B is in contact "with the vertical wall 26 of the landfill" C ".

At the bottom of the cover "B" is the ring 20 which has on its inner face a series of angled teeth 19 that join the ring 20 with the vertical wall 14 of the cover "B" and which are intended to allow the rotation of the ring 20 by screwing the cover "B" to the landfill " C "but prevent the rotation of the ring 20 by unscrewing the cover" B "because they engage with the angled teeth 31 of the landfill" C ", causing the teeth 19 to separate from the cylindrical body 14 of the cover" B "and detaching the ring 20 that is separated into two parts by having two vertical cuts 21.

The landfill "C" as seen in Figure 4, has a hole 22 in the central part of the horizontal surface 23 through which the rod 13 of the cover "B" is introduced.

At the top of the landfill "C" a circular hole 25 is located where the liquid inside the landfill "C" is expelled. the vertical wall 26 of the landfill "C" ends within a radius 24 in order to return the liquid to the interior of the landfill when it stops pouring.

In the upper part of the landfill "C # is a vertical cylinder 27 connected to the outer body by a series of vertical segments 28 which aims to guide the movement of the valve" D "on the vertical axis of the landfill" C ".

The horizontal bottom surface 32 of the landfill "C" has an angled wall 33 that ends at a horizontal surface 34 that joins the horizontal surface 59 of the tube "F" by welding Ultrasonic or glue. When the landfill "C" is fixed to the tube "F" the horizontal surface 32 of the landfill "C", it is at the height of the horizontal surface 58 of the tube "F".

The circular surface 36 of the landfill "C" has a small cord 35 that engages with a series of cords 48 that has the vertical surface 50 of the gasket or valve seat "E" and that make a tight seal when the landfill "C is coupled" "to the gasket or valve seat" E ".

The gasket or valve seat "E" has in the central part a vertical rod 44 with the slightly angled wall 45 that is inserted into the lower cavity 43 of the valve "D" in order to guide the movement of the valve "D" on its vertical axis. The rod 44 is connected to the vertical cylindrical surface 49 of the gasket or valve seat "E" by means of the horizontal segments 54 and forms with the cylindrical surface 49 the cavity 53 through which the liquid passes from inside the bottle. The cylindrical surface 49 ends on a horizontal cylindrical surface 47 where the valve "D" sits and a seal is made, with surfaces 41 and 42.

The gasket or valve seat "E" has a concentric cylinder 46 that makes it difficult for the liquid to pass through the cylindrical surface 40 of the valve "D" in order to make the plug more irrellenable. When the bottle is tilted to pour the liquid, the valve "D" moves on its vertical axis and releases the passage of the liquid. The horizontal surface 51 of the gasket or valve seat "E" has on its underside a series of cords 52 that make a seal with the horizontal surface 70 of the neck of the bottle "G". The vertical cylindrical surface 56 has on its outer face a series of cords 55 that make a tight seal with the surface 73 of the neck of the bottle "G".

The cylindrical vertical surface 56 ends in a radius 57 to facilitate the introduction into the neck of the "G" bottle, which also has a radius 71 for the same purpose.

The tube "F" has a series of vertical segments 60 in order to limit the entrance of the gasket or valve seat "E" when making contact with the horizontal surface 51.

In order to fix the tube "F" to the neck of the bottle "G", a series of angled anchors 62 are positioned which are positioned at the waist 74 when the surface 61 of the anchors 62 makes contact. Because the material with which The tube is molded is flexible, allows angled anchors 62 to slide over angled surface 72 and be placed at the waist 74 of the neck of the "G" bottle.

The inner part of the cylindrical surface 67 has a series of vertical segments 63 and 64 that end at angles 65 and 66 and are placed between the vertical segments 75 of the neck of the bottle "G" in order to avoid turning the tube "F "when the cap is placed on the neck of the" G "bottle. To guide the placement of the tube "F" in the neck of the bottle "G", a series of vertical segments 68 ending in the spokes 69 have been placed. The lower part of the circular surface 67 ends at the height of the radius 76 of the neck of the "G" bottle providing a continuous silhouette for having the same diameter.

Plug Assembly First, the non-refillable mechanism is assembled by pressing the valve "D" into the gasket or valve seat "E" and the landfill "C". Once the mechanism is assembled, the lower part of the landfill "C" is attached to the upper part of the tube "F" by means of ultrasonic welding or by means of some glue. The cover "B" is assembled by pressure with the cover "A". Finally, the cover "B" is screwed to the landfill "C" by turning the cover "A" until it reaches the upper horizontal surface of the landfill "C".
