Definitions

  • caps made of thermoplastic resins which are provided with a skirt that is adapted to extend over the aforementioned annular bead on the mouth of the bottle and to reach under the bead of the bottle by means of an inwardly directed annular projection formed on the inside of the skirt of the cap. It is also known to provide a projection or tab member on the outside of the skirt which facilitates lifting the closure off a bottle, i.e., it facilitates opening the bottle.
  • the present invention avoids all of the these disadvantages. It solves in a completely new manner the objects of insuring the genuineness of the bottled contents while providing a re-usable plastic bottle closure.
  • the aforementioned lift tab member or lever which serves as a means for prying off the closure, is connected to the skirt of the closure by means of one or more linking members or connecting webs, at least one of which becomes torn as soon as a filled and capped bottle is opened for the first time.
  • the closure shows permanent visible damage while, nevertheless, the cap itself remains re-usable for subsequent and repeated capping of the bottle if such is desired.
  • the tab member is shaped such that the closure can be pried off either by means of a mechanical bottle opener or by hand.
  • the tab consists of a downwardly open pocket the side walls of which are substantially thinner than its front wall.
  • the front wall of the pocket can consist of a frame with thick-walled edge members while the surface within this frame is made thin and is connected at its middle portion to the skirt by means of a connecting bridge member.
  • a finger or bottle opener When a finger or bottle opener is inserted under the front wall into the pocket and starts lifting the cap, this then causes not only the weak side walls but also the weak portions of the front Wall to tear until full leverage takes place to lift the closure off the bottle.
  • Bottled gas-containing beverages such as beer or carbonated water tend to develop considerable pressure, especially when being transported or at increased temperatures.
  • high-density polyethylene e.g., polyethylene having a density of about 0.93 gram/cm.
  • the sealing member of the closure from a softer material, that is, from an elastic or resilient thermoplastic resin, e.g., polyethylene having a density of only about 0.916 gram/cm ⁇ , i.e., to provide the cap with a separate sealing insert made of this material.
  • an elastic or resilient thermoplastic resin e.g., polyethylene having a density of only about 0.916 gram/cm ⁇
  • polyethylene resin because of its elastic properties and its easy fabrication by injection molding.
  • this material is substantially permeable by gases such as carbon dioxide, especially at higher temperatures.
  • This disadvantage can be overcome in the case of the present invention by coating the underside of the cap with a film having only a small permeability for carbon dioxide.
  • FIGURE 1 is a vertical section of the neck of a bottle in section
  • FIGURE 2 is a vertical section of the novel cap in section
  • FIGURE 3 is a view in elevation of the closure illustrated in FIGURE 2, placed on the bottle shown in FIGURE 1, except, however, that the closure is shown rotated through an angle of ninety degrees with reference to the closure shown in FIGURE 2;
  • FIGURE 4 is a vertical section of the closure with a somewhat different tab member
  • FIGURE 5 is a view in elevation of the closure illustrated in FIGURE 4, rotated through an angle of ninety degrees;
  • FIGURE 6 is a vertical section of still another embodiment of the closure; and 7 FIGURE 7 is a view in elevation of the closure illustrated in FIGURE 6, rotated through an angle of ninety degrees.
  • the bottle shown in FIGURE 1 has at the edge of its mouth an outwardly projecting circular bead 1 which serves to retain a so-called crown closure.
  • FIGURE 2 represents a closure 2 made from a thermoplastic resin.
  • Skirt 3 of this closure has an inwardly projecting bead 4 which is adapted to reach under the outer bead of the bottle afterbeing snapped on andthereby to hold the cap in closed position.
  • a tab 5 which projects laterally from the skirt in an otherwise known manner serves for pulling off the closure. Its special form, as it is variously shown in FIGURES 2-7, repre sents the essence of the invention. As can be seen from FIGURES 2 and 3, the tab 5 is connected to skirt 3 by means of a connecting web 6 which is considerably thinner than the skirt of the closure or the back of the tab. When the bottle is being opened the finger or bottle opener first bends the flexible back of the tab somewhat upward before the actual prying action takes place.
  • the thin connecting web 6 is torn and becomes a permanent indication that the bottle has been opened.
  • the closure is made reusable while the genuineness of the bottled contents is safeguarded as long as the closure remains intact.
  • the lower edge 7 of the skirt is thin and clings to the neck of the bottle in order to preclude a bottle opener from finding a point of attack other than tab 5.
  • a cylindrical sealing member 8 which is adapted to extend into the mouth of the bottle and which is shown in FIGURE 2, as this reduces by about one half the pressure area on which the free gas can act and thereby reduces the likelihood of the closure being popped off by the internal pressure.
  • FIGURES 4 and 5 A somewhat different embodiment of tab is illustrated in FIGURES 4 and 5.
  • tab 9 is in the form of a downwardly open pocket having side walls 17 which are considerably thinner than the front wall.
  • a V-shaped notch 10 is provided at the juncture between the front wall of the pocket and skirt 3 of the closure.
  • a finger or bottle opener is inserted under the front wall of the pocket whereupon lifting of the cap necessarily tears the thin side walls 17 of the pocket before the front wall can effect its full lifting action.
  • FIGURE 4 further shows a separate, otherwise wellknown sealing insert 18 which contains a hollow annular ring or sealing extension 19 adapted to protrude into the mouth of the bottle.
  • the edge of this sealing member rests in a circular recess 11 inside skirt 3 whereby the insert is anchored in the closure.
  • FIG- URES 6 and 7 Another variation of the invention is shown in FIG- URES 6 and 7.
  • the front wall 12 forming the back of tab 13 is composed of a frame of thick edge mem bers '14 whereas the tab pontion 15 within the frame is a relatively thin membrane. In a center portion this membrane is connected to skirt 3 by means of a thick walled bridge member 16 or baffie which extends only the closure thus removed from the bottle.
  • Closures of which several embodiments have been de-. scribed above, can be placedon bottles by means .of: known and conventional automatic bottle capping ma- 1 chines without damaging the thin connecting webs or tear portions which forms the seal. Any subsequent opening of the capped bottle is, however, impossible without damaging this seal, regardless of whether the cap is pried olf by hand or by means of a bottle opener.
  • the bottle After partial emptying the bottle can be tightly but easily re-closed by hand.
  • a resilient cap adapted for closing a bottle having an outwardly projecting bead at the lip thereof, said cap comprising a skirt adapted to extend over and to reach under said bead, an outwardly projecting tab mern- 1 her in the form of a downwardly open pocket attached to said skirt, said tab member having a front wall and a side wall which is substantially thinner than said front wall.
  • a closure according to claim 1 wherein said front wall of the tab comprises a frame composed of thick walled frame members containing a thin surface, said thin surface having a center portion connected by a bridge member to the skirt.
  • a closure according to claim 1 which comprises l cylindrical sealing member composed of a soft flexible; thermoplastic resin and adapted to protrude into and i tightly abut the inner wall of the mouth of a bottle.
