Definitions

  • the present invention relates generally to tamper proof seals for containers such as bottles and the like. Specifically, the invention relates to an inner seal having a pull-tab formed thereon.
  • U.S. Patent No. 4,501,371 discloses a tamper indicating, non-resealable closure or seal for a container.
  • the closure includes a foil sheet having a layer of thermoplastic material on each surface thereof.
  • the foil sheet is thermally bonded to a container opening.
  • a liner ring overlies the foil sheet and is thermally bonded to the thermoplastic material of the foil.
  • the seal includes a layer of 0.0015 inches thick aluminum foil with a coating of heat activated adhesive on its bottom surface. A portion of a 0.005 inches thick two-ply sheet formed of polyester laminated paper is glued to the top surface of the aluminum foil.
  • the seal is shaped like a disc with the unattached half of the polyester-laminated-to-paper sheet forming a pull-tab used to peel of the seal from a container.
  • the disclosed Stanpac stamped seal has several drawbacks.
  • the paper layer employed in the tab is susceptible to curling in the presence of moisture. Additionally, because the tab flaps freely, it can become misaligned during a capping of a container and then can get in the way of the cap.
  • U.S. Patent No. 5,004,111 also discloses a closure for a container.
  • the closure has a pull-tab formed of a layer, a portion of which is secured by an adhesive to a foil layer.
  • the present invention provides a new closure. More specifically, the present invention provides a closure seal with a pull-tab and a method of making the same, particularly for sealing a container such as bottle.
  • a tamper indicating closure for a container has a seal portion and a pull-tab portion.
  • the seal portion has an upper surface and a lower surface. The lower surface is securable around an opening of the container.
  • the pull-tab portion (preferably made of polyethylene) is secured across the upper surface of the seal portion and has a pull-tab formed therein.
  • the closure also has a layer of polyester film bond over an upper surface of the pull-tab.
  • the seal portion is a foil layer.
  • the closure further has a layer of release material which separates a portion of the pull-tab from the remainder of the pull-tab portion.
  • the pull-tab portion is a unitary member formed of a first layer of a plastic material and a second layer of the plastic material at least portions of which are fused together.
  • the second layer is extruded onto a sheet of the first layer.
  • the invention further provides a method for manufacturing a closure seal for a container.
  • a method for manufacturing a closure seal for a container Preferably comprising the method are the steps of: providing a sheet of a first layer of plastic material (preferably polyethylene); positioning a release layer onto a portion of the first layer so that there is a covered surface portion and an exposed surface portion of the first layer; and extruding a second layer of the plastic material onto the exposed surface portion and the release layer so that the second layer fuses to the exposed surface but does not fuse to the release layer, the unfused portion of the first or second layer defining a pull-tab.
  • plastic material preferably polyethylene
  • the a circular disc is cut from the layers so that the disc partially overlaps the release layer.
  • a foil layer is secured to the second layer.
  • an adhesive layer is added to the foil layer.
  • the adhesive layer is heat activated.
  • heat is applied to the adhesive layer.
  • the first layer of plastic material is backed onto a sheet of polyester film.
  • the polyester film, the first layer, the release layer, and the second layer are pressed between two rollers while the second layer is partially melted.
  • At least one of the rollers is heated.
  • multiple strips of the release layer are positioned on the first layer so that the strips are placed apart from one another.
  • a further advantage of the present invention is to provide a closure seal which can be efficiently manufactured.
  • Another advantage of the present invention is to provide a closure seal having a unitary pull-tab portion with a pull-tab unitarily formed therein.
  • Yet another advantage of the present invention is to provide a closure seal having a pull-tab which resists breaking.
  • a closure seal 1 as illustrated in Figure 1-3, is provided for sealing a container 10, such as a bottle.
  • the closure seal 1 can be an inner seal which is provided under a cap 11 of the container 10.
  • the closure seal 1 includes a pull-tab portion 12 and a seal portion 13.
  • the pull-tab portion 12 is a unitary member in which a pull-tab 16 is unitarily formed.
  • the pull-tab portion 12 is secured entirely across an upper surface of the seal portion 13.
  • a lower surface of the seal portion 13 is sealable around an opening 18 of the container 10.
  • the pull-tab 16 is formed in the pull-tab portion 12 so that the pull-tab 16 can be gripped to remove the closure seal 1, including the seal portion 13, from the opening 18 of the container 10.
  • the pull-tab 16 extends from the remainder of the pull-tab portion 12 at a hinging edge 20.
  • the pull-tab portion 12 preferably is made of a resilient and flexible plastic. Therefore, the hinging edge 20 allows the pull-tab 16 to be deflected upward, as illustrated in Figures 2 and 3, so that a user can grip the pull-tab 16.
  • the unitary construction gives the closure seal 1 strength and resistance to failure that could arise from pulling on the pull-tab 16.
  • the construction of the present invention avoids the use of adhesives or superfluous components to connect a pull-tab, as occurs, for example, in U.S. Patent Nos. 4,961,986 and 5,004,111.
  • the pull-tab portion 12 is preferably constructed of a first layer 22 and a second layer 24 made of the same material.
  • the two layers 22 and 24 are fused, or melted together where indicated by the dotted line in Figure 3.
  • a portion of the first layer 22 forms the pull-tab 16.
  • the fused portions of the first layer 22 and second layer 24 and unfused portion of the second layer 24 form the remainder of the pull-tab portion 12.
  • the first layer 22 and second layer 24 preferably are partially separated at the pull-tab 16 by a release layer 26 interposed therebetween.
  • the separation is necessary to define the pull-tab 16.
  • the release layer 26 is one material that resists bonding to the plastic material of the pull-tab portion 12. Therefore, the release layer 26 can keep the pull-tab 16 in the first layer 22 from bonding to the remainder of the second layer 24 during an operation of fusing the first layer 22 and second layer 24 together.
  • the pull-tab 16 is formed by a separation in the pull-tab portion 12, wherein the separation is generally parallel to the seal portion.
  • the closure seal 1 can include several layers.
  • a backing layer 28 can be formed on top of the unitary pull-tab portion 12.
  • the backing layer 28 is preferably formed of polyester, but can be made of some other resilient material that can be provided in a sheet.
  • the backing layer 28 adds strength to the pull-tab 16.
  • a heat activated adhesive layer 32 can be used to adhere the seal 1 to the opening 18 of the container 10.
  • the heat activated adhesive layer 32 can be formed of an ionomer that softens as it is heated to adhere to a surface.
  • Such an ionomer is marketed under the registered trademark Surlyn of E.I. DuPont DeNemours & Company.
  • Such an adhesive can be heated by conduction and or some other means to soften and adhere as desired.
  • the seal portion 13 is preferably formed of a metal foil, although some other substance, such as a plastic film, could be used.
  • the seal portion 13 is preferably an aluminum sheet having a thickness of about .0010 inches.
  • the seal portion 13 separates from the container 10 or tears when a user pulls on the pull-tab 16 to open the container 10.
  • the seal portion 13 readily indicates tampering because tears therein are irreparable.
  • the seal portion 13 is durable enough to withstand contact incidental to handling and shipping.
  • the seal portion 13 is impermeable by liquid and vapor. Thus, the seal portion 13 effectively seals out moisture and germs from the container 10.
  • the adhesive layer 32 can be weaker than the seal portion 13, so that the entire seal portion 13 separates without tearing from the container 10 when the seal 1 is removed by a user.
  • the pull-tab portion 12 is preferably constructed of a plastic material which is suitable for extrusion.
  • the plastic used should have a high enough melting temperature so that heat dissipated by the seal portion 13 from the heat activation of the adhesive layer 32 during a sealing operation does not melt or deform the pull-tab portion 12.
  • one such plastic material is polyethylene.
  • the plastic material used to form the pull-tab portion 12 should be strong enough to withstand the pulling forces on the pull-tab 16 exerted by the user.
  • the closure seal 1 is preferably shaped as a disc. Most container openings are circular. Thus, the closure seal 1 can be made to conform to the shapes of the openings of most containers. The closure seal 1 could, however, be another shape that conforms to the shape of a container opening.
  • first layer 22 and second layer 24 are fused together along about half of the area of the closure seal 1.
  • the fused area between the first layer 22 and the second layer 24 could be greater or less, so long as the pull-tab 16 can exert sufficient leverage to remove the closure seal 1 from the container 10.
  • a process for forming the closure seal 1 is illustrated.
  • a sheet 34 having the backing layer 28 is backed with the first layer 22 is carried by a first roller 36.
  • a group of second rollers 38 carries strips of the release layer 26.
  • At least one roller 38 with the release layer 26 material must be provided, however multiple rollers 38, as shown, are desirable.
  • five rollers 38 are provided which carry release layers 26.
  • the multiple release layers 26 are separated from one another by a distance about equal to the width of the release layers 26.
  • the release layers 26 roll under a third roller 40, which positions the release layers 26 onto the top of the first layer 22 in spaced apart relationship.
  • An extruder 42 is provided which extrude a sheet-shaped molten flow of extruded plastic 44 of the material used to form the second layer 24 which when fused with the first layer 22 forms the unitary pull-tab portion 12. This extruded plastic 44 partially cools as it leaves the extruder 42.
  • a fourth roller 46 carries a sheet of material such as foil, or sheets of material, to form the seal portion 13.
  • the seal portion 13 and the extruded plastic 44 are both fed under a fifth roller 48.
  • the fifth roller 48 positions the extruded plastic 48 onto the top of the first layer 22 and the release layer 26 where the extruded plastic 44 forms the second layer 24.
  • the fifth roller 48 and a sixth roller 50 press the layers together.
  • the second layer 24 is warm and partially melted.
  • the second layer 24 fuses with the first layer 22 between the strips of release material 26.
  • the foil 30 bonds to the second layer 24.
  • the seal portion 13 can be secured to the second layer 24 by means of a suitable adhesive, such as those mentioned in the above-identified patents.
  • the seal portion 13 can include a backing of the adhesive layer 32, in which case the composite sheet 52 would also include the adhesive layer 32.
  • heat can be provided by the fifth roller 48, the sixth roller 50 or by both that the composite sheet securely bonds together.
  • the composite sheet 52 is preferably collected on a seventh roller 54 for storage.
  • the composite sheet 52 can be collected on the seventh roller 54 without the adhesive layer 32 where the adhesive layer 32 is to be applied at some later time.
  • the composite sheet 52 is passed through a cutting device (not shown) that cute or Stamps out the closure seals 1.
  • a cutting device not shown
  • multiple disc-shaped closure seals 1 can be cut from the composite sheet 52.
  • the cutting process is such that each disc overlaps one of the release layers 26 by the desired amount. In the embodiment shown, about one-half of each disc-shaped closure seal 1 overlaps one of the release layers 26.
  • a closure seal 1 can then be sealably adhered around a container opening 18 by heating the adhesive layer 32 and positioning the closure seal 1.
