Description

i PLUG II. LEADING AND INVIOLABLE FOR BOTTLES OR CONTAINERS FIELD OF THE INVENTION The present invention relates to caps for bottles or containers containing liquids, such as alcoholic beverages, which require a tamper-proof cap and mechanism of the non-refillable type that allows the liquid to escape from the inside of the bottle, but not the liquid inlet inside said bottle.

BACKGROUND OF THE INVENTION There are currently on the market several designs of tamper-proof or non-refillable caps or combining these two characteristics that have some flaws, which causes that they do not fulfill the task of guaranteeing to the consumer that the bottle is not refilled or the original liquid can not be adulterated . It is an object of the present invention to overcome these faults and provide the bottler with a plug that meets the requirements of having an inviolable screw cap, an effectively non-refillable mechanism and a cap that can not be removed from the neck of the bottle without destroying it.

This object is achieved through the design of the screw cap that guarantees that, once the cap to the weir is screwed, it can not be unscrewed without releasing a lower ring and it separates into two parts, making it evident that it has been previously unscrewed. the lid. The overcap can be of a different color to the lid, which makes the lack of the ring more evident.

Furthermore, in order to ensure a hermetic seal, a double seal has been designed on the lid by means of two concentric rings and a rod in the central part.

In a very important way and to make the plug effectively non-refillable, a mechanism has been designed consisting of an upper valve, a lower valve, a glass sphere, a packing and a spillway.

Finally to ensure that the cap can not be removed from the bottle without destroying it, horizontal anchors have been designed inside the tube that are housed under a waist or circular cavity that has the neck of the bottle. To avoid being able to extract the tube, it is molded with a plastic resin that has a softening temperature higher than one hundred degrees centigrade.

DESCRIPTION OF THE INVENTION The present invention relates to a particular design of plugs for liquids of the non-refillable inviolable type.

The non-refillability feature is achieved through a mechanism consisting of a gasket, two valves, one upper and one lower, a glass sphere that is placed between the valves and a weir. This mechanism allows the flow of liquid in one direction and prevents the flow of liquid in the opposite direction. When pouring the liquid, the valves separate from their seats along with the glass sphere and when refilling the bottle the valves block the access to the interior of the bottle when resting on the package.

The invention is characterized by a non-refillable mechanism consisting of a lower valve that is placed in the lower part of the packing, of a glass sphere that is placed on the lower valve and an upper valve. The dump is assembled at the top of the packing. This combination of valves is effective in preventing the passage of liquid into the bottle and allowing the liquid to escape when the valves and the glass sphere move, when it is desired to pour the liquid from inside the bottle. When the bottle is in a vertical position, the first lower valve is wedged in its lower vertical circular surface of the package, due to the weight exerted on it by the glass sphere, to a series of small vertical segments that have the lower part of the package and that retain said lower valve making it difficult to move on the vertical axis. Therefore when wanting to pour the liquid from the bottle the lower valve moves when the liquid hits a central cavity of the valve, achieving the displacement of this valve from its seat and allowing the passage of the liquid.

The non-refillable mechanism has a second upper valve that is housed in the upper part of the gasket that serves to block the access of the liquid to the inside of the bottle. When pouring the liquid the upper valve separates from the seat with the packing when the glass sphere hits the lower part of the second upper valve.

The upper valve has on its lower surface a series of teeth that are opposed to another series of teeth that has the lower valve on its upper surface, this with the aim that when rotating the upper valve the lower valve is also rotated. The reason for the valves to turn when unscrewing the lid is to break the contact with the packing that can hinder the displacement of the valves, especially when the liquid contains sugar or some other material that tends to "adhere the surfaces .

The screw cap has two closing surfaces to prevent the liquid from escaping when the cover is screwed to the landfill. One of the closures is achieved by one or several concentric rings that are introduced into the upper landfill cavity blocking the exit orifice. The other closure is achieved by a concentric rod that has the lid on the inner surface. This rod is introduced to the interior of the landfill by a central cavity and by screwing the plug to the landfill the lower part of the rod, which ends in a crosspiece, is introduced into a conical cavity that has the upper valve. The rod presses the upper valve against the packing, blocking the liquid outlet. The stem also has the purpose of rotating the valve when the lid is unscrewed, because the crosshead is inserted in the conic cavity of the upper valve and draws the valve when the lid is turned.

The screw cap has in its lower outer part a ring having on its inner wall a series of angled teeth which are intended to allow the cap to be screwed on and prevent the ring from rotating when the cap is unscrewed, because said teeth they are opposed to a series of angled teeth that the landfill has on its outer lower surface. The ring is attached to the body of the lid by means of a series of horizontal segments or bridge_3, which by not turning the ring when unscrewing the lid breaks the union of the ring to the body of the lid and causes the ring to detach and fall. The ring has two cuts at one hundred and eighty degrees from each other, so that when the ring separates from the body of the cover, it falls into two parts.

On the outside of the lid is placed an overcap that is assembled to the lid by means of horizontal cords that oppose each other to other cords that the lid has. The lid has been designed with a circular grooved surface that opposes a grooved surface that has the upper inner surface of the overcap so that when the overcap is rotated, the lid is also rotated.

Because it is necessary that the lid always be screwed in the same position in relation to the landfill, two stops at the top of the landfill that are opposed to two stops that have the lid on the upper surface have been placed at one hundred and eighty degrees. inside. By means of these stops, the teeth of the cover ring are positioned in the required position so that when the cover is unscrewed for the first time, they are opposed to the teeth of the weir and the horizontal segments or bridges that join the ring break. to the body of the lid.

A tube that forms the outer cylindrical part of the plug is glued or welded by ultrasound in the upper part to the landfill.

The tube has on its inner cylindrical surface a series of angled horizontal surfaces or anchors that allow to slide the tube on the neck of the bottle and to lodge it under a circular waist of the neck of the bottle, and that avoid the displacement of the tube when trying to remove it from the bottle. The tube has on its inner cylindrical surface a series of vertical segments or nerves that are opposed to some notches or vertical drops that the neck of the bottle has, preventing the tube from rotating.

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 together with the attached drawings, in which: Figure 1 is a sectional view of the non-refillable and inviolable cap assembled with all its parts and which is placed on the neck of the bottle or containers.

Referring to figure 1 in it, the overcap "A" was seen; cover "B"; landfill "C"; the "D" package; the upper valve "E"; the glass sphere "F"; the lower valve "G"; the "H" tube and the neck of the bottle or container II J II, Figure 2 shows the overcap "A" having a vertical wall 1 that can have on its outer surface a series of grooves 3 to be able to better hold the overcap "A". In the upper inner part of the vertical wall 1 a series of vertical segments 2 are placed which are opposed to another series of vertical segments 14 having the cover "B" in the upper outer part of the vertical wall 6, in order to that overcap "A" and lid "B" do not rotate with each other.

In the middle part of the vertical wall 1 of the overcap "A" have been placed a series of horizontal cords 4 that * are opposite the similar cords 7 that has the vertical wall 6 of the lid "B" in order to remain fix the cover "B" inside the overcap "A". The overcap "A" has a cylindrical horizontal surface 18 which serves to limit the entrance of the lid "B" by being in contact with the cylindrical horizontal surface 23 of the lid "B". The surface or vertical wall 1 of the overcap "A" ends in a horizontal ring 5 that when assembled to the lid "B" makes contact with the upper part of the ring 9 of said lid "B". The vertical surface or wall 6 of the cover "B" ends in its upper part at an angle 16 to facilitate assembly on the overcap "A".

The lid has the vertical surface 6 which has on its inner wall a helical cord 8 which serves to screw the lid "B" to the weir "C" with the helical cord 31.

In the lower part of the cover "B" a ring 9 attached to the body of said cover "B" appears by means of horizontal segments 19. These horizontal segments 19 make contact with the vertical surface 6 by means of a series of small bridges 20 that are broken when first unscrewing the cover "B" of the weir "C" by means of a series of angled teeth 21 located on the inner wall of the ring 9, increasing the thickness of the wall 22 and opposing one another. series of teeth 24 also angled in the opposite direction that has the spillway "C" and which prevent the ring 9 from rotating when unscrewing the cover "B", which causes the bridges 20 to break and the ring 9 to be separated from the surface vertical 6.

The ring 9 can be separated into two or more parts.

Because it is necessary to correctly position the angled teeth 21 of the lid "B" in relation to the angled teeth 24 of the weir "C", a vertical surface 15 which limits the height of the interior of the lid "B" is designed. turn of the threaded to oppose this to the vertical surfaces 37 that has the dump "C" on the outside of the horizontal circular wall 38.

In the lower part of the upper horizontal wall 17 of the lid "B", figure 3, a circular surface 12 ending in one or more cords 13 is projected towards the inside and intended to produce a hermetic seal when introduced into one or more horizontal circular cavities 35 having the weir "C", figure 4, in its horizontal circular stop 34, blocking the exit orifice 36 from landfill "C". Also in the lower part of the horizontal surface 17 of the screw cap "B" a vertical circular vase 10 is projected that ends in a crosspiece 11 that is introduced into the dump "C" through the central circular hole 41 allowing the crosshead 11 is inserted in the conical circular cavity 65 having the first valve "E", figure 6, in the upper part of the cylinder 66. The circular conical cavity 65 has a vertical segment 68 that has for object to turn the valve " E "when the tap" B "is unscrewed. It also helps the rotation of the valve "E" that the circular cavity 65 has the conical vertical wall that presses the crosshead 11 of the cover "B".

Of the circular horizontal wall 40 of the verteder "C" projects a cylinder 42 which is intended to guide the lateral displacement of the first valve "E", limiting the lateral movement of the cylinder 66 of said first valve. The vertical displacement of the valve "E" is limited by gluing the upper circular surface 64 with the surface or circular wall 40 of the weir "C".

The circular horizontal surface or wall 38 of the landfill "C" has a radius 39 on the upper interior wall, which has the purpose of cutting off the flow of the liquid when it is poured and preventing it from trickling down the outside of the landfill "C" To fix the landfill cylinder 42"C" a series of vertical segments 33 that make contact with the inner wall of the vertical surface 32 has been provided.

In the inner part of the vertical surface 32 of the landfill "C" a horizontal bead 30 is placed which opposes a horizontal cord 28 that has the "D" packing on the vertical surface 46, preventing the landfill from separating "C" of the "D" package when both pieces are assembled.

The circular horizontal surface 29 of the landfill "C" limits the entrance of the package "D" when making contact with the vertical segments 48. It also limits the entrance of the packaging "D" to the landfill "C" the circular horizontal surface 27 of the landfill "C" that meets the circular surface 51 of the "D" package.

The circular surface 25 of the weir "C" has an angled vertical wall 26 which joins the circular surface 88 and the annulus 87 of the tube "H" by means of glue or by means of ultrasonic welding.

As regards the package "D" it has on its upper circular surface 46 a first series of vertical segments 45 which limit the vertical displacement of the first valve "E" and which allow liquid to flow between them. These vertical segments 45 terminate in their upper part in a radius 43 to facilitate introducing the valve "E" into the package "D".

The package "D" has a circular horizontal surface 49 that serves as a seat to the valve "E" when making contact with the horizontal circular surface 69 of said valve, effecting a hermetic seal when the valve "E" is pressed vertically by the rod. 10 of the cover "B".

The horizontal circular surface 53 of the package "D" has a series of circular cords 52 which when in contact with the circular horizontal surface 100 of the bottle "I" help to effect a hermetic seal between both pieces.

The outer circular wall of the wall 51 of the package "D" is angled in order to facilitate the assembly of the package "C" when introducing the tube "H".

The vertical circular wall 54 of the package "D" has on its outer wall a series of horizontal cords 56 that make a hermetic seal with the bottle "I" when in contact with the circular surface 103.

The package "D" has a second series of vertical segments 55 which guide the lower valve "G" in its lateral displacement and allow the passage of liquid between these vertical segments 55. The vertical segments 55 terminate in their upper part in a radius 50 to facilitate introducing the valve "G" into the package "D".

The packing "D" has in its lower part two vertical cylindrical surfaces 58 and 61 that effect a lateral closing with the valve "G" when being in contact with the vertical surfaces 57 and 60 of the "D" packing with the vertical surfaces 78 and 81 of the second lower valve "G". A seal is also made between the "D" gasket and the second valve "G" when the horizontal circular surfaces 59 and 63 of the "D" gasket are in contact with the corresponding horizontal circular surfaces 80 and 83 of the "G" valve.

A third series of small vertical segments 62 whose circumference is slightly smaller than the diameter of the cylinder 84 having the valve "G" have been placed in the lower part of the package "D". When the valve "G" is in the closed position with the "D" packing, the small vertical segments 62 wedge the "G" valve on the cylinder 84, preventing the displacement of the "G" valve. When it is desired to pour the liquid from the bottle "I" it is possible to displace the valve "G" when the liquid that has the bottle "I" collides inside the cavity 86 of the valve "G", breaking the wedging between the valve " G "and the packing" D ". The lower wall of the cylinder 84 terminates in an angled surface 85 in order to facilitate the positioning of the "G" valve within the "D" package.

The liquid flows from the inside of the bottle "I" through the hole 73 of the "D" packing when the valves "G" and "E" move when the bottle "I" is tilted. The liquid flows through the spaces between the vertical segments 55 and 45 of the "D" package and through the orifice 36 of the "C" weir.

The first valve "E" has a horizontal circular surface 67 that guides the displacement of the valve "E" by limiting its lateral movement the vertical segments 45 that have the upper cylindrical surface or wall 46 of the "D" package.

The upper cylindrical wall 46 has a diameter almost equal to the inner diameter of the wall or cylindrical surface 32 of the landfill "C", effecting a hermetic seal when these two parts are assembled.

In the lower wall of the cylindrical surface 67 of the first valve "E" have been designed two angled surfaces 70 that guide the valve "E" to effect a closure between the valve "E" and the package "D" when the surface 69 is in contact with the horizontal ring 49 of the "D" package.

In the lower part of the first valve or upper valve "E" a series of vertical segments 71 are located which are intended to limit the lateral displacement of the glass sphere "F" and to oppose a series of vertical segments 76 having the second valve or lower valve "G" that rotate the valve "G" when the cover "B" is unscrewed because when the crosspiece 11 is inserted in the conical cavity 65 the valve "E" and the the rotary movement is transmitted to the valve "G" when the vertical segments 71 and 76 are opposed and the possible adhesion between the "G" valve and the "D" package is broken.

The inner lower part of the first valve "E" has a spherical shape 72 to house the glass sphere "F" '.11 inside it, when displaced when the liquid is poured from inside the bottle "I".

The vertical segments 76 of the valve "G" have an almost straight side wall 75 which opposes the vertical segments 71 of the valve "E" when the cover "B" of the spillway "C" is unscrewed. The other wall 74 of the vertical segments 76 is circular in shape. Between these vertical segments the glass sphere "F" is housed limiting its lateral displacement, since these segments 76 project upwards from the valve "G" with a radial surface 77 that centers the glass sphere "F".

The upper body of the second valve "G" is formed by a cylinder 79 having an exterior vertical wall or surface 78 that limits the lateral movement of the valve "G" by being in contact with the vertical segments 55 of the packaging "D".

In the lower part of the cylinder 79 of the second valve or lower valve, a horizontal circular surface 80 is located which, when in contact with the horizontal circular surface 63 of the "D" packing, makes a closure between the "G" valve and the packing " D "when the valve" G "is pressed by the weight of the glass sphere" F ".

The lower part of the valve "G" is formed by a vertical cylinder 82 that effects a lateral closing in contact with the vertical cylindrical surface 81 with the vertical cylindrical surface 57 of the "D" package.

The vertical cylinder 82 of the valve "G" has in its lower part a horizontal cylindrical surface 83 that effects a horizontal closing with the packing "D" when the horizontal cylindrical surface 83 rests on the horizontal cylindrical surface 59 of the "D" package.

The tube "H" has a vertical cylindrical surface 89 located in the inner part a series of anchors 91 formed by lower angled surfaces 92 and 93 and upper angled 90. When assembling the cap to the bottle "I" slide the angled surfaces lower 92 and 93 allowing the anchors 91 to be positioned below the horizontal circular surface 104 of the bottle "I" and because the anchors 91 have a diameter slightly larger than the diameter 105 of the "I" bottle no displacement is allowed of the "H" tube, the cap being firmly attached to the "I" bottle. The upper angled surfaces 90 of the tube "H" are kept in intimate contact with the angled surface 102 of the bottle "I" preventing movement of the cap, once it has been placed in the bottle "I".

To prevent the rotational movement of the tube "H" with respect to the bottle "I", a series of vertical segments 94 and 95 are placed on the inner cylindrical surface 89 of the tube "H" which are placed between the vertical segments 107 of the bottle "I" opposing each other, avoiding the rotary movement of tube "H".

The lower part of the vertical segments 94 and 95 end at an angle 96 to guide these vertical segments to be placed between the vertical segments 107 of the "I" bottle.

To start the correct placement of the "H" tube in the "I" bottle, small vertical segments 97 have been designed.

The lower part of the cylindrical surface 89 ends at an angle 98 so that when the cap is placed on the bottle "I" is on an angled surface 108 that has the neck of the bottle "I" forming a continuous silhouette between the cap and the lower part of the neck of the bottle "I".

To facilitate placing the cap on the neck of the bottle "I" the cylindrical top 106 ends in two radii ^ 99 and 101.

PLASTIC MATERIALS EMPLOYEES The pieces that form the plug are molded of plastic resins determining their physical characteristics according to the performance they perform.

The tube "H" is molded with a high-temperature plastic softening resin, such as polycarbonate, in order to prevent the cap of the bottle "I" being removed with heat. The landfill should be molded with a resin that has a melting temperature very similar to that of the "H" tube when these pieces are joined by ultrasound.

ASSEMBLY OF THE PLUG The plug assembly is made by making two pre-assemblies and a final assembly. The lid is preassembled inside the overcap. The non-refillable mechanism is pre-assembled by placing the lower valve inside the packing, then the glass sphere, then the upper valve, and finally the dump is placed on the packing by pressure.

The final assembly is made by adhering the non-refillable mechanism to the tube by means of glue or ultrasonically welded and then screwing the lid to the landfill.
