Definitions

  • This invention relates to a stopper bottle comprising a bottle with an opening and a stopper, detachably connected with the bottle, which closes the opening, the stopper being arranged to be pulled from the bottle for opening the bottle and to be pressed into the opening of the bottle for closing the bottle again, the stopper being made up of a rigid upper cap and a lower cap, made of flexible material and connected with the upper cap, a sidewall of the upper cap extending downwards into a space enclosed by the lower cap, and a sidewall of the lower cap extending into the opening of the bottle.
  • stopper bottles have been used for packaging ground coffee or instant coffee.
  • a disadvantage of the known stopper bottle is that the stopper bottle, before being purchased by a consumer, that is, when, for instance, it is still on the shelf in a shop or in a storehouse of a supplier, can be opened by pulling the stopper from the bottle and subsequently be closed again by placing the stopper back onto the bottle again without this being evident from the bottle.
  • Today's society requires more and more that a stopper bottle, before being opened by a consumer, cannot be opened and subsequently closed again without this being evident from the bottle.
  • the object of the invention is to provide a stopper bottle which obviates the above-mentioned disadvantages.
  • the invention is characterized in that the lower cap further comprises a skirt which extends around a neck of the bottle and which, at its upper end, is connected via a tear line with an upper end of the sidewall of the lower cap, and opening the bottle for the first time requires pulling the skirt from the sidewall of the lower cap along the tear line.
  • Such a construction allows the cap to be removed from the bottle only when the skirt is pulled from the rest of the cap via the tear line.
  • the skirt is absent, however, it will be immediately clear to a consumer that the bottle may have been opened.
  • a stopper bottle has been obtained, which precludes the possibility of its being opened by pulling the stopper from the bottle without this being noticeable.
  • the skirt and the lower cap are made of the same material.
  • the invention also relates to a method for manufacturing a stopper bottle as described above.
  • the lower cap comprising the skirt is placed on the bottle, such that the sidewall of the lower cap extends into the opening of the bottle, and the skirt extends around the neck of the bottle.
  • the upper cap is pressed tightly onto the lower cap.
  • the lower cap may then further be heated, so that the skirt shrinks and clings tightly around the neck of the bottle, before the upper cap is placed on the lower cap or after the upper cap is placed on the lower cap.
  • the stopper bottle 1 comprises a bottle 2 and a stopper 4 which closes off an opening, being circular in this example, of the bottle.
  • the stopper 4 is arranged to be pulled from the bottle for opening the bottle and to be pressed into the bottle for closing the bottle again.
  • the stopper 4 is made up of a rigid upper cap 6 which, at its lower end, comprises a circumferential sidewall 8 which tapers downwardly in this example.
  • the stopper comprises a lower cap 10 made of a flexible material, connected with the upper cap 6, having a sidewall 12 which is circumferential in this example.
  • the sidewall 12 has likewise a conical shape, with the diameter of the lower cap decreasing in downward direction.
  • the sidewall 8 of the upper cap extends downwardly into a space 14 enclosed by the lower cap 10.
  • the sidewall 8 extends into a space enclosed by the sidewall 12 of the lower cap 10.
  • the sidewall 12 of the lower cap extends into the opening 3 of the bottle 2.
  • the lower cap further comprises a skirt 16 which extends around a neck 18 of the bottle 2. At its upper end, the skirt 16 is connected via a tear line 20 with an upper end of the sidewall 12 of the lower cap 10. As can be properly seen in Fig. 2, in this example the profile of the skirt 16 corresponds with the profile of the neck 18 of the bottle 2. In this example, the skirt and the lower cap are made of the same material.
  • the sidewall 8 of the upper cap 6 comprises, adjacent the tear line 20, an outwardly offset shoulder 22.
  • the sidewall 12 of the lower cap 10 here merges at its upper end into a bent portion 24 extending outwardly in radial direction along the underside of the shoulder 22, with an outermost portion 26 of the bent portion 24 connected to the skirt 16.
  • the bent portion 24, in this example, extends at least substantially in horizontal direction.
  • the tear line 20 extends roundabout along the neck of the bottle in the bent portion 24.
  • the skirt Adjacent its lower end 28, the skirt further comprises an edge 30 extending outwardly in radial direction. Further, the bottle 2 comprises, above this edge 30, a neck edge 32 bottle 2 comprises, above this edge 30, a neck edge 32 extending outwards and to above the edge of the skirt. It further appears from Fig. 2 that the skirt, adjacent its lower end, further comprises a circumferential edge 34 extending outwardly in radial direction. As can be properly seen in Fig. 3, the skirt further comprises on its outer side a lip 36 for tearing loose the skirt 16 from the rest of the lower cap 10.
  • the stopper 4 cannot be removed from the bottle as long as the skirt 16 is present.
  • the skirt 16 is even made of shrink foil, with the result that it is pulled tightly around the neck of the bottle.
  • the edge 30 hooks under the neck edge 32, rendering it entirely impossible, even when applying great force, to pull the stopper 4 from the bottle.
  • a consumer after he has purchased the bottle 1, wishes to remove the stopper 4 from the bottle 2, he does so by gripping the lip 36 and tearing the skirt 16 loose from the remainder of the lower cap 10 along the tear line 20.
  • the bottle 2 can be opened by pulling the stopper 4 off the bottle.
  • the stopper 4 can also be re-placed again, with the lower cap, owing to its flexibility, forming a proper seal again with the opening 3 of the bottle 2.
  • the skirt may have been open. Accordingly, when upon purchase of a stopper bottle, the skirt is still present, a consumer can be certain that the bottle has not been open yet.
  • a stopper bottle as described hereinabove can be carried out very simply.
  • the lower cap is placed on the bottle, together with the skirt already attached to it. This results in a situation according to Fig. 1, with the upper cap omitted.
  • Placing the lower cap on the bottle can be easily carried out because the lower cap is made of a flexible material.
  • at least the skirt comprises a material which shrinks upon supply of heat. Accordingly, by supplying heat to the skirt of the lower cap, it can cling firmly around the neck of the bottle 2.
  • the upper cap Before or after the skirt is, optionally, heated, the upper cap can be pressed tightly onto the lower cap.
  • the upper cap and lower cap are thereby connected to each other via a snap connection, known per se, which has been utilized in stopper bottles for a long time already. This snap connection has the property of subsequently disallowing the upper cap 6 to be pulled from the lower cap.
  • the invention is not limited to the embodiments outlined hereinbefore.
  • the opening of the bottle can have a shape different from the circular shape.
  • the opening can be, for instance, of square or hexagonal design.
  • the stopper 4 will then have a shape corresponding to that of the opening. Such variants are all understood to fall within the scope of the invention.
