Definitions

  • the present invention relates to closures for containers such as bottles, and is concerned with such closures which are of the tamper-evident/non-refillable type.
  • the invention is particularly applicable to closures for containers for liquids, such as all types of beverages including alcoholic beverages.
  • the invention is applicable for containers which require a tamper-evident and a non-refillable function to avoid adulteration of the contents.
  • Tamper-evident/non-refillable closures for containers are well known and are required to minimize the adulteration of alcoholic beverages by refilling the bottles when only the tamper-evident feature is used. By combining these two features the contents or the bottle are protected against tampering or adulteration of the original liquid.
  • the present invention provides a tamper-evident/non-refillable closure for containers comprising a cylindrical tube designed to fit around and engage the outer surface of the neck of the container, a movable valve member cooperating with the valve seat and adapted to form a seal therewith, a pourer extending around the valve seat and attached to the cylindrical tube by ultrasonic welding and an internally threaded cap which can be secured to the pourer, and has a lower ring that detaches and breaks in two parts, when the cap is first unscrewed from the pourer.
  • the various elements of the closure are preferably integral mouldings of any desired, preferably resilient plastic materials.
  • the tube preferably carries a plurality of projections on its inner surface which are deformed outwardly when the tube is placed over the neck of the container and which snap inwardly behind a shoulder defined by the neck of the container, so as to retain the tube in position on the neck of the container. Because the tube is moulded from plastic resin of appropriate physical and chemical characteristics, such as polycarbonate, once it is placed on the neck of the container, it will be extremely difficult if not impossible, to remove it with out its destruction.
  • the tube preferably has a plurality of vertical ribs on its inner surface which are adapted, in use, to engage projections on the neck of the container and thus prevent rotation of the tube with respect to the container.
  • the tube preferably also has a plurality of vertical ribs on its inner upper surface for the purpose of holding in place the valve seat, when the closure is assembled.
  • the tube can be assembled to the pourer by ultrasonic welding or using appropriate adhesive materials, so that both parts become one.
  • valve seat has an upper circular vertical surface with a series of rings on the outer surface that, when assembled to the lower opening of the pourer, snap in place against a ridge that the pourer has, and makes a hermetic seal between these two parts and engage both parts in place.
  • the upper inside circular surface of the valve seat has a horizontal ring where the valve blocks the flow of liquid, when the cap is screwed to the pourer and exerts pressure on the vertical axis against a sphere or marble that sits on the upper surface of the valve.
  • the valve seat preferably has in its lower part a cavity opened at the lower end, where a sphere or marble is placed for the purpose of detaching the valve from the valve seat, when the liquid is poured from the container. It is preferred that the valve seat has in its upper inside circular surface a series of ribs for the purpose of guiding the displacement of the valve on the vertical axis of the closure.
  • the pourer has an annular tube and a plurality of integral webs within it, which engage the valve member and marble and retain it in its desired position with respect to the valve seat.
  • the outside circular surface of the pourer has a threaded section that engages corresponding threads placed inside the circular vertical surface of the cap, to screw both parts.
  • the pourer preferably has in its outside lower circular surface a series of angled teeth that allows the cap to be screwed to the pourer, but engage corresponding angled teeth located on the inside lower part of the cap and prevents it from rotating when the cap is first removed from the pourer.
  • the lower part of the cap is secured to the upper part by a series of small vertical segments or bridges that break, when the cap is first removed from the pourer.
  • the lower part of the cap has two vertical 180 degree cuts, that allow the lower part of the cap or ring to break in two parts, when the vertical segments or bridges are broken.
  • the cap preferably carries a central depending stem which, when the cap is screwed onto the pourer, exerts pressure on the sphere or marble, located in the upper horizontal surface of the valve member, and at the same time pressures the valve against the circular ring of the valve seat, blocking the flow of liquid through this opening.
  • the cap preferably carries a depending annular flange which, when the cap is screwed onto the pourer, engages and substantially forms a seal with an upstanding annular flange on the pourer.
  • the closure has a two-stage seal, of which the first stage is constituted by the valve member and the valve seat, and the second is constituted by the engaging annular flanges.
  • the valve is preferably made so that the upper and lower surfaces are similar and contain a semicircular cavity, where the sphere or marble is held in its place and an outer circular cavity that sits on the ring of the valve seat.
  • the two spheres or marbles preferably can be made of glass or other appropriate rigid material.
  • the present invention provides a tamper-evident/non refillable closure for a container, comprising means for dispensing the contents from the container, a valve member located within the dispensing means for selectively opening and closing a path through the dispenser; valve actuation means to facilitate opening and closure of the valve and a closure member engagaeble with the dispensing means, the closure member having a tamper-evident portion integrally formed therewith.
  • the invention also embraces a container, such as a bottle carrying such a tamper-evident/non-refillable closure.
  • the closure comprises an integrally threaded cap A which is screwed onto the pourer B.
  • a sphere or marble E Within the pourer is a sphere or marble E and a valve C with a valve seat D.
  • a sphere or marble F is contained in the lower part of the valve seat D .
  • Attached to the pourer is a cylindrical tube G which extends around the neck H of the bottle or container.
  • FIG. 2 illustrates the screw cap A which comprises an upper disc with a depending peripheral circular wall 1 with helicoidal threads 2 on the inside surface which, in use, engage external threads 21 on the pourer B.
  • a stem 10 depending from the underside of the upper disc 8 passes through a circular opening 16 defined by the upper surface 15 of the pourer B and exerts a vertical pressure on the sphere or marble E which at the same time transmits the vertical pressure to the valve C.
  • On the underside of valve C there are two inclined surfaces 49 and 50 that are pressed against an annular horizontal surface 36 on the valve seat D, and normally form a seal therewith to prevent the flow of liquid through a circular opening defined in the valve seat D by the vertical circular surface 35.
  • a depending annular flange or tube 9 which is integral and coaxial with the cap A and has the purpose of making a second seal when the cap A is in the closed position by contacting the vertical surface 17 of the pourer B.
  • the lower end of flange 9 is bevelled to facilities its introduction into pourer B.
  • the external cylindrical surface 1 of the screw cap A can be formed with a series of vertical ribs 11 that allow cap A to be gripped securely when removing it from pourer B.
  • a ring 5 is formed that is separated from the upper circular wall 1 by a horizontal cut 3 made to such a depth that allows the small vertical segments or bridges 4 to unite ring 5 to the upper circular surface 1.
  • Ring 5 has on the inside vertical wall a series of angled teeth 6 at such an angle that allow the screw cap A to be screwed to pourer B, but prevent ring 5 from rotating in the opposite direction by a series of corresponding angled teeth 23 located on the outside lower surface of vertical wall 22 of pourer B. By not permitting ring 5 of cap A to rotate on the unscrewing direction, the small segments or bridges 4 break and separate ring 5 from the upper vertical surface 1 of cap A.
  • Two vertical cuts 7 at 180 degrees are made on ring 5 for the purpose of separating ring 5 in two parts, when the vertical segments or bridges 4 are broken.
  • annular flange or tube 19 which limits the displacement of sphere or marble E on a vertical axis, relative to pourer B.
  • Vertical wall 22 of pourer B has on its lower part a horizontal surface 24 from which angled teeth 23 protrude upwards.
  • Lower part of pourer B has an inclined vertical surface 25 that guides the pourer into ring 54 located on the upper cylindrical surface 65 of tube G, so that pourer B and tube G can be welded by ultrasonics or attached to horizontal surface 26 of pourer B with horizontal upper surface 55 located in the inside wall 65 of tube G.
  • the upper part of pourer B has a horizontal circular surface 12 that has a radius 13 towards circular cavity 14, so that the liquid does not run on the outside of pourer B, but returns to the inside of pourer B, when the liquid stops flowing from the container H.
  • the liquid flows from the inside of pourer B through spaces 47 left between radial spaced segments 29 and horizontal circular surface 18.
  • External cylindrical wall 32 of valve seat D has a plurality of peripheral rings 33 on its outer surface which, when the closure is assembled makes a tight, hermetic seal with the internal cylindrical surface 27 of pourer B, and also secures valve seat D when assembled to pourer B, by means of ring 28 located on the inside vertical surface 27 of pourer B.
  • the upper part of cylindrical wall 32 is angled 31, to facilitate assembly of valve seat D to pourer B.
  • the upper part of horizontal circular surface 37 limits the placement of valve seat D when it is assembled to pourer B by coming in contact with circular horizontal surface 26.
  • the lower part of horizontal circular surface 37 has a number of rings 38 which, when the closure is placed on the container neck H, makes a tight, hermetic seal with horizontal circular surface 69 of container neck H.
  • Vertical circular surface 39 has on its outside wall a number of rings 40 that when the closure is applied to the container neck H makes a tight, hermetic seal with vertical circular surface 68.
  • Vertical circular surface 39 has on its inside wall a number of vertical segments 41 for the purpose of guiding the displacement of sphere or marble F on a vertical axis, relative to valve seat D.
  • valve seat D has an inclined vertical surface 42 that forms a seal 43 with the sphere or marble F, and forms circular cavity 46 through which the liquid flows from the inside of container H.
  • horizontal ribs 45 and vertical ribs 44 are located on the lower part.
  • valve C To center the placement of sphere or marble E, a semicircular cavity 51 is located on the horizontal surface of valve C. Valve C is designed so that it can be placed correctly on either side on to valve seat D.
  • sphere or marble E The purpose of sphere or marble E is to exert vertical pressure on valve C and maintain valve C on circular surface 36 of valve seat D, blocking the entrance of liquid, when the container or bottle H is placed upright.
  • sphere or marble F The purpose of sphere or marble F is to detach valve C from valve seal D when liquid is poured from container or bottle H.
  • the upper inside circular wall 65 of tube G has a number of vertical segments 57 ending in horizontal surface 56, that prevent valve seat D from sliding downwards, when the closure is assembled by limiting displacement of circular surface 37.
  • a series of angled segments 59 project inwards, so that when the closure is applied to the container or bottle neck H, horizontal surface 58 of angled segments 59 engage under shoulder or ring 72 of the container or bottle neck H, not allowing tube G to be removed.
  • angled segments 59 have a lower inclined surface 60 that slips onto inclined circular outer surface 71 of the container or bottle neck H.
  • vertical circular surface 65 of tube G has a series of vertical ribs 61 and 62 that engage corresponding vertical ribs 73 on the container or bottle neck H.
  • the lower end of vertical ribs 61 and 62 form angles 63 and 64 to facilitate positioning of the closure on the container or bottle neck H.
  • a series of longer and less prominent ribs 66 are located in the lower inside vertical surface 65.
  • the lower part of tube G ends as radius 67 to form a continuous surface with the lower part 74 of container or bottle neck H.
  • the seven parts that make up the tamper-evident/non-refillable closure are assembled as follows: First sphere or marble F is placed inside valve sat D, followed by valve C, sphere or marble E and pourer B, forming the non-refillable mechanism. Next the non-refillable mechanism is attached or ultrasonic welded to tube G. Once the non-refillable mechanism and tube G are assembled, the tamper-evident cap A is screwed onto pourer B.
  • the closure is applied to the container or bottle neck H by applying vertical pressure on the top of the closure, forcing the angled segments 59 of tube G to engage under shoulder or ring 72 of the container or bottle neck H, as shown in Figure 1.
