MXPA97006347A - Plug of inviolable and irrelenable type for bottles or simila containers - Google Patents

Abstract

A bottle cap of the inviolable and non-refillable type that includes an overcap of the inviolable type, a screw cap, a spillway, a valve, a packing or valve seat, a fixing ring and a cylindrical tube, characterized in that the overcap has its lower part is a ring stretched on its lower face and joined to the upper part by means of small vertical segments or bridges that when the cap is unscrewed for the first time, the vertical segments or bridges are broken because the ring can not turn when opposing a surface stretched circular that has the tube in its upper part. The ring has two vertical cuts at 160 degrees of separation that cause the ring to be separated into two parts when the vertical segments or bridges break. The plug is provided with a mechanism of the non-refillable type formed by a landfill, a valve and a packing or valve seat, which allows the liquid to escape, but not the entrance thereof. A tube inside which the non-refillable mechanism is inserted and has a horizontal cord where the fixing ring is housed inside the tube. The tube has on its upper inner surface a series of small vertical segments or teeth that prevent the spillway from turning when opposing a corresponding series of small segments or teeth that have the spillway on its surface lower cylinders on its outer face. The improvements essentially consist in that the inviolable ring is formed in the lower part of the overcap and the rotation of the ring is prevented when opposing a flute having the tube on its upper surface. The assembly of the mechanism with the tube has also been modified, introducing the mechanism inside the tube instead of assembling the mechanism hooked the weir to an angled box of the tube.

Description

PLUG OF INVIOLABLE AND IRRELENABLE TYPE FOR BOTTLES OR SIMILAR CONTAINERS Field of the Invention The invention relates to caps for bottles or containers containing liquids, such as alcoholic beverages, which require a cap of the inviolable type and a mechanism of the non-refillable type that allows the liquid to escape from the inside of the bottle or container, but not the entry of it.

Background of the Invention There are several designs of tamper-evident or non-refillable caps on the market or with these two characteristics combined, which have some flaws, which means that they do not meet the increasingly important need to protect the contents of bottles or containers and guarantee the consumer that the bottle or container was not refilled or the original liquid was adulterated.

The designs of this invention are an improvement to the invention of the Mexican patent application No. 9501883 in order to eliminate certain faults, to improve its operation and offer another design alternative.

Synthesis of the Invention The improvements essentially consist of the following: The tamper-evident ring that emerges from the plug has been formed in the lower wall of the overcap by means of a continuous horizontal cut in which some small vertical ribs have been cut partially, which has the overcap inside them and which form the bridges that join the ring with the top wall. In the case of the invention of the Mexican patent application No. 9501883, the inviolable ring is molded in the lid and it is not necessary to cut the overcap.

The non-refillable mechanism is assembled to the tube by introducing it from the bottom instead of hooking the weir to an angled eyebrow that has the tube on the upper circular surface.

The landfill of this design has the liquid outlet through a lateral cavity that is different from that of the Mexican patent application No. 9501883. A circular housing has also been designed in the landfill where the lid skirt is introduced in order to avoid the outlet of the liquid when the plug is screwed. The Mexican patent application No.9501883 does not have this lodging.

A series of vertical ribs have been added to the package or valve seat to guide the displacement of the valve on the vertical axis of the plug.

The fixing ring has been modified by designing a cavity between the anchor and the vertical wall that allows the anchor to open or spring easily, requiring less pressure when placing the cap on the neck of the bottle.

The novelty as well as the original features of this invention will be better understood and more broadly referred to in the description of the parts in conjunction with the accompanying drawings.

Detailed description of the invention Referring to Figure 1, it shows the overcap "A", the cover HB ", the dump" C ", the valve MD", the packing or valve seat "E", the fixing ring "F", the tube "G" and the neck of the bottle "H".

Figure 2 shows the overcap "A" having a vertical wall 1 which in turn has a series of grooves 2 to be able to better hold the overcap "A". In the vertical inner wall 1 a series of horizontal rings 3 are located which are opposed to horizontal rings 16 of the cover "B" in order to prevent them from separating from the overcap "A" when these pieces are assembled together.

In the upper inner wall of the surface 1 a series of vertical grooves 4 are located which are opposed to a series of vertical grooves 14 having the upper wall 10 of the cover "B" in order to avoid turning the cover "B" in relation to overcap "A" when both pieces are assembled. The upper part where the grooves 14 of the cover "B" end form an angle 15 in order to facilitate the assembly of the cover "B" to the overcap "A".

To the vertical wall of the overcap "A" is made a horizontal cut 5 in the lower part that separates the upper part of the lower part, forming a ring 7 that is joined to the upper part by means of vertical segments or bridges 6 that have been partially cut and that join the ring 7 with the upper body 1 of the overcap "A". The ring 7 has two vertical cuts 9 that separate it into two parts. The horizontal cut 5 of the overcap "A" is made after molding the overcap "A" and the two cuts 9 are made when molding the overcap MA ".

The inner part of the ring 7 carries a series of vertical grooves 8 which are intended to prevent the ring 7 from rotating by unscrewing the cover "B" for the first time by means of a series of vertical grooves 62 located in the vertical upper wall 72 of the tube "G" which prevent the ring 7 of the overcap "A" from rotating and causing the vertical segments 6 of the ring 7 that join it to the upper vertical wall 1 of the overcap "A" to fracture. In this way, the tamper-proof characteristic of the cap is achieved, since when the lid "B" that has been assembled to the overcap "A" is unscrewed for the first time, the ring 7 is detached and falls in two parts due to the fact that the bridges or vertical segments 6 are fractured when the ring 7 can not be rotated because its movement is blocked by the grooves 8 which oppose the grooves 62 of the tube "G".

The threaded cap MB "carries within the vertical wall 10 a helical cord 11 of one or several entries for the purpose of being screwed into the landfill" C "with the corresponding ropes 18 which are located in the vertical wall 17 of the landfill" C " "By screwing the cover" B "to the landfill" C ", the turn of the thread is limited when the horizontal surface 13 of the cover" B "comes into contact with the horizontal circular surface 33 of the landfill" C ".

To obtain a hermetic seal, the interior of the cover "B" has been provided with a vertical inner ring or skirt 12 which is inserted in the cavity 21 of the landfill "C" formed by the vertical walls 22 and 24. In this way the cover "B" being screwed to the landfill "C", the passage of the liquid to the outside is blocked by the interference of the circular ring 12 of the cover "B" when it enters the cavity 21 of the landfill "C".

The landfill "C" has in the upper part a vertical surface 24 that ends in a radius 25 in order to prevent the liquid from trickling down the outside wall of the landfill "C", when the liquid is no longer poured. Inside the landfill "C" a vertical cylinder 23 attached to the vertical wall 22 is located by means of a series of vertical segments 27 between which the liquid flows when it is poured from the interior of the container. The cylinder 23 is closed at the top by the horizontal circular surface 26 and has inside it a series of vertical segments 20 which are intended to guide the displacement of the valve "D" on the vertical axis when the liquid is poured. The vertical cylinder 23 has in its lower part a horizontal circular surface 19 which has as its object to avoid introducing any wire or object similar to the interior of the landfill "C" to lift the valve "D" of its seat on the circular surface 46 of the packing or valve seat "E". At the bottom of the landfill "C" is located a vertical circular surface 28 having on the outside a series of teeth 30 which are intended to prevent the spillway "C" from rotating when assembled with the pipe "G" when opposing a series of corresponding teeth 66 having the tube "G" on top of the vertical surface 67.

By assembling the landfill "C" to the pipe MG "it stops its displacement from the landfill" C "inside the pipe" G "when the horizontal circular surface 29 of the landfill" C "meets the circular horizontal surface 65 of the MG pipe" . The lower part of the vertical surface 28 of the landfill "C" ends in a horizontal ring 31 which serves as a stop to the packing or valve seat "E" when both parts are assembled, as the horizontal surface 45 of the packing or valve seat opposes "E" When the landfill "C" is assembled to the valve seat or packing "E", it is provided inside the vertical surface 28 with a horizontal ring 32 that opposes a horizontal ring 43 having the vertical wall 51 of the packing or Valve seat "E" to prevent separation of both parts. The vertical surface 51 terminates at an angle 52 to facilitate the assembly of the valve seat or packing "E" to the landfill "C".

Inside the vertical wall 51 of the packing or valve seat "E" several vertical ribs 41 have been placed in order to guide the displacement of the valve on the vertical axis of the plug. These vertical ribs 41 terminate at a radius 41 to facilitate the assembly of the cap.

The packing or valve seat "EM has a vertical circular surface 44 which is intended to block the entry of liquid when the valve" D "is placed on the circular seat 46.

The horizontal circular surface 47 limits the entrance of the valve seat or packing "E" to the neck of the bottle "H" when in contact with the circular horizontal surface 76.

The horizontal circular surface 45 of the valve seat or package "E" is positioned on the shelf 54 having the vertical wall 53 of the fastening ring "F" and supporting and centering the valve seat or packing "E" when the stopper is assembled . The lower part of the shelf 54 of the fixing ring "F" has a cylindrical surface resting on the horizontal surface 76 of the neck of the bottle "H" when placing the stopper.

The lower part of the packing or valve seat "E" has a vertical cylindrical surface 48 having a series of horizontal rings 49 which are intended to seal the neck of the bottle "H" when in contact with the wall vertical 74 when the cap is assembled to the neck of the "H" bottle.

The central part of the valve seat or packing "E" has a cavity 40 through which the liquid flows inside the "H" bottle. In order to facilitate the molding of the "E" valve seat or gasket, several horizontal ribs 50 have been designed.

The valve "D" has in its upper part a vertical cylinder 35 that limits the displacement of the valve when it meets the horizontal circular surface 26 of the weir "C".

The lower part of the valve "D" has a vertical cylinder 36 that guides the displacement of the valve when its lateral movement is limited by the vertical ribs 41 of the valve seat or packing "E".

The vertical cylinder 36 of the valve "E" has in its lower part two angled surfaces 37 and 38 that when the valve "D" is positioned on the horizontal ring 46 of the packing or valve seat "E", they block the entrance of the liquid to the inside of bottle "H".

In the upper and lower part of the valve "D" two cylindrical cavities 34 and 39 have been designed in order to decrease the volume of the "D" valve and facilitate the molding of this piece.

The fastening ring "F" has a circular wall 56 ending at the bottom on an angled surface 60 which has the purpose of fixing the ring inside the tube "G" as its displacement is limited by the corresponding ring 68 having the wall 67 of the "G" tube.

In the lower part of the wall 56 of the fixing ring "F", horizontal surfaces or anchors 58 have been designed which, when the cap is placed on the "H" bottle, are positioned below the waist 78 which has the neck of the bottle "H". To facilitate placing the cap on the neck of the "H" bottle, an angled surface 59 is designed to allow sliding on the angled outer surface 77 of the neck of the "H" bottle.

Between the vertical wall 56 and the horizontal surface or anchor 58, a cavity 57 remains in the fastening ring "F" in order to allow the horizontal surface or anchor 58 to flex when the stopper is placed and slide on the angular surface 77 of the bottle "H".

The vertical wall 67 of the tube "G" has on its inner surface a series of vertical ribs 70 which are intended to avoid turning the tube "F" when placed on the neck of the bottle "H" when the upper part 69 of the nerves 70 to the nerves or drops 79 having the neck of the bottle "H".

In the upper wall 67 of the tube "G" a small ring 63 has been designed which forms the cavity 64 where the lower part of the ring 7 of the overcap MA "is housed when the plug is assembled.

The lower part of the vertical wall 67 of the tube "G" ends at an angle 71 in order to rest on the circular surface 73 of the neck of the bottle "H".

The neck of the bottle "H" has a radius 75 to facilitate the entry of the cap to the neck of the bottle.

Materials Used All the pieces that form the plug are molded with thermoplastic materials determining their physical characteristics according to the function they perform.

It is of particular importance that the fixing ring is molded with a heat-resistant resin such as polycarbonate, to avoid that when the cap is heated it can be removed from the neck of the bottle, as is the case with polyethylene or polypropylene resins.

Plug Assembly As a first step, the non-refillable mechanism formed by the packing or valve seat "E", the valve "D" and the landfill "C" is assembled.

The next assembly step consists of placing the fixing ring "F" in a special mandrel and then placing the non-refillable mechanism in the upper part of the mandrel and resting on the fixing ring "F". Subsequently the tube "G" is placed, leaving the fixing ring "F" and the mechanism in the inner part of the tube "G". The next step is to screw the cover "B" to the landfill "C" and then place the overcap "A" on the cover "B".
