Definitions

  • ABSTRACT An end closure for an easy opening resealable container, the end having a dispensing aperture initially sealed by an internal sealing layer adhered to the inner surface of the end around the aperture and a plug type resealing member extending through said aperture and bonded to said sealing layer,
  • the plug type resealing member is provided with a lower portion which is smaller than the dispensing aperture and extends therethrough, the bottom wall thereof being bonded to the sealing layer.
  • the upper portion of the rescaling member is larger than the dispensing aperture and is provided with a depending straight wall which fits into the aperture with interference between the peripheral wall of the aperture and the depending straight wall of the rescaling member to thereby releasably seal the easy opening container subsequent to the tearing of the sealing layer.
  • the present invention relates generally to easy opening containers'such as cans. More particularly the present invention relates to easy opening containers which are releasably resealable by means of a plug type resealing member.
  • Another container construction suitable for easy opening, utilizes a tab which may or may not be integrally formed with the container end closure and which is depressable into the can body.
  • the main purpose of this type of construction is the elimination of littering which may result from the unconcerned discarding of removable sections of the container.
  • this type of end closure construction is subject to the same disadvantage as the pull tab construction in that no means are provided for resealing the container once it has been opened.
  • Another type of easy opening container construction which has recently'been developed provides an internal sealing patch adhered to the inner surface of the container end around the dispensing aperture.
  • the opening means provides is an external member which is adhered to that portion of the sealing patch covering the aperture and which extends above the can end so that when removed the portion of the sealing patch co-extensive with the aperture is torn against the periphery of the aperture severing it from the balance of the patch.
  • the periphery of the aperture is provided with a sharp cutting edge against which the sealing patch can be readily torn.
  • the Balocca patent discloses a container having an aperture being surrounded by a raised bead which provides a seat for a plug type plastic reclosure member which is inserted through the aperture and bonded to that portion of the sealing patch which internally covers and seals the aperture.
  • the periphery of the aperture due to the annular bead, is disposed above both the plane of the central panel of the end and the sealing patch to thereby insure against prematurely rupturing the sealing patch during transportation and handling of the container.
  • the removal of the plastie type plug from the container causes the sealing patch to be torn 'at the sharp edge of the aperture periphery thereby leaving a flange-like extension at the bottom portion of the plug.
  • the container may then be reclosed by reinsertion of the plug into the aperture and engagement of the flange-like extension with the underside of the container end at the periphery of the aperture. If there is internal pressure within the container subsequent to the reclosing thereof, the flangelike extension of the plug which is engaged with the underside of the container is forced thereagainst thereby resealing the container. However, if there'be no internal pressure within the container no resealing occurs and the contents can be readily spilled. Thus, although a reclosure member is provided with this type of container it provides at most a very imperfect and inadequate seal.
  • a primary object of the present invention to provide a container which is initially sealed and easily opened without the aid of special tools, and in addition may be releasably resealed to prevent inadvertent spillage of the contents and to hermetically seal the container.
  • the easy opening container of the present invention includes a container end closure seamed about its periphery to a container body, the end closure being provided with a dispensing aperture.
  • the dispensing aperture is initially sealed by an internal sealing patch adhered to the inner surface of the end around the aperture.
  • a plug type resealing member is provided which extends through the aperture and is bonded to the sealing patch so that upon removal of the resealing member from the container a portion of the sealing patch coextensive with the dispensing aperture is torn away, thus breaking the seal and opening the container.
  • FIG. 1 is a perspective view of the top portion of an easy opening resealable container according to the present invention
  • FIG. 2 is a cross-sectional view of the plastic, plug type, pull tab removed from the container of FIG. 1;
  • FIG. 3 is an enlarged, partial cross-sectional view of the container of FIG. 1 taken along line 3-3 of FIG. I;
  • FIG. 4 is an enlarged, partial cross-sectional view of the container similar to FIG. 3 with the plug type pull tab partially removed from the container;
  • FIG. 5 is an enlarged, partial cross-sectional view of the container similar to FIG. 3, but in the resealed condition;
  • FIG. 6 is an enlarged, cross-sectional detailed view of a portion of FIG. 3;
  • FIG. 7 is an enlarged, cross-sectional detailed view of a portion of FIG. 5.
  • FIG. 8 is a cross-sectional view similar to FIG. 3 of a slightly modified form of theeasy opening resealable container of the present invention.
  • FIG. 1 the upper portion of an easy opening resealable container, generally designated 10, having an end closure 12 incorporating the easy opening resealable feature of the present invention secured to the end of the container body 14 in any acceptable manner.
  • the container body 14 may be of any conventional type having a suitable bottom end closure (not shown) secured thereto.
  • End closure 12 is formed with a generally planar central panel, generally designated 16, surrounded by a peripheral reinforcing bead 18 which at its outer edge merges into upwardly extending countersink wall 20.
  • the upper portion of wall 20 merges with outwardly extending flange 22 which, after assembly of container body 14 and end closures 12, becomes a portion of seam 24.
  • End closure 12, as well as container body 14, may be fabricated from any suitable material or combination of materials such as tin plate, coated steel, aluminum, plastic, etc.
  • End closure 12 is provided with a dispensing aperture, generally designated 26, and also may be provided with a vent aperture, generally designated 28, as most clearly seen in FIGS. 3, 4, and 5.
  • the apertures while depicted in the drawing as being circular, may be of any suitable shape such as key hole, oval, radially elongated, tear drop, etc. While the size of aperture 26 is not critical it is to some extent dependent on the product (not shown) packaged in the container. Thus, when the container is subjected to internal pressure, such as when the contents are carbonated beverages, aperture 26 should be as small as is consonant with proper pouring in order to enable the closure to withstand the internal pressures while at the same time permitting proper pouring of the contents.
  • aperture 26 may be appreciably larger.
  • Vent opening 28 is preferably distantly spaced on central panel 16 from dispensing aperture 26 and is provided for venting the container to the atmosphere.
  • Raised dimples are formed in central panel 16 around apertures 26 and 28 respectively, as clearly seen in FIGS. 3 to 7.
  • the peripheries 34 and 36 of the respective apertures 26 and 28 are sloped downwardly toward the apertures and the respective peripheral walls 38 and 40 are inclined upwardly toward the apertures.
  • the lower edges 42 and 44 of the respective peripheral walls 38 and 40 are preferably disposed above the plane defined by the adjacent inner surface of the central panel 16.
  • the upper edges 46 and 48 of the respective peripheral walls 38 and 40 are inwardly disposed with respect to the apertures and form wedgelike protrusions extending into the apertures.
  • the layer or patch 50 is preferably fabricated from flat sheet stock or tape comprising a suitable thin, readily tearable, pressure resistant, impervious material such as aluminum or other metal foil or laminations of metallic foils and other materials.
  • the sealing layer or patch 50 may be of any convenient shape or size to cover the apertures and of a suitable thickness for its intended purpose.
  • the upper surface of patch 50 is fully coated with a preapplied layer or lamination, generally designated 52, of an adhesive which bonds the patch to the inner surface of central panel 16.
  • patch 50 may extend onto reinforcing bead 18 to thereby increased its resistance to creepage when the container is subjected to internal pressures.
  • the bottom surface of patch 50, as well as its exposed edges, may if desired be protected by a thin coating of an inert organic resin (not shown) to protect the material from possible corrosive action resulting from exposure to the contents of the container. 1
  • a resealing member 54 is pro vided.
  • the resealing member is preferably injection molded from a suitable flexible thermoplastic resin such as polyethylene, polypropylene, polyurethene, phenoxy, a vinyl modified polyurethene, a random copolymer of ethylene and acrylic acid, etc.
  • the resealing member 54 is basically comprised of a plug 56 for the dispensing aperture, a plug'58 for the vent aperture, and a pull handle 60.
  • Plug 56 is formed with a smaller lower portion, generally designated 62, a larger upper portion, generally designated 64, and a centrally disposed inner recess 66.
  • lower portion 62 of plug 56 is smaller than aperture 26 and therefore is adapted to pass therethrough to contact sealing layer 50.
  • the larger portion 64 of plug 56 is provided with a depending straight wall-having a width that is greater than both the lower portion 62 and aperture 26 so that when the plug is forced into the aperture an interference fit is established between peripheral wall 38 of aperture 26 and the depending straight wall of'upper portion 64 of the plug.
  • the edge 46 of peripheral wall 38 is wedged into the depending straight wall of upper portion 64 of the plug thus effectively sealing the aperture 26.
  • a sloped transition piece, generally designated 68, is provided between the smaller lower portion 62, which may have a depending straight wall, and the depending straight wall of the larger upper portion 64 in order to facilitate the insertion of portion 64 into aperture 26.
  • Recess 66 is provided in plug 56 in conjunction with groove 70 for the purpose of forming a button 72 and also for maintaining the wall thickness of member 54 uniform throughout to thereby aid in the injection molding of member 54.
  • Plug 58 is structured similarly to plug 56 but because of its much smaller size it is not provided with a button corresponding to button 72 of plug 56.
  • the lower portion 74 of plug 58 is smaller than vent aperture 28 and therefore adapted to pass therethrough to contact sealing layer 50, as clearly seen in FIG. 3.
  • Upper portion 76 of plug 58 is provided with a depending wall having a width that is greater than lower portion 74 and aperture 28, and upon insertion 28, it seals the aperture in a manner identical to that described with respect to plug 56.
  • a sloped transition piece, generally designated 78 extends between lower portion 74, which may be provided with a depending straight wall, and the depending straight wall of upper portion 76 of plug 58 to facilitate insertion of upper portion 76 into aperture 28.
  • Recess 80 in the upper end of plug 58 extends therein to thereby maintain the wall thickness of the resealing member uniform.
  • Flange-like webs generally designated 82, extend circumferentially around the upper extremities of plugs 56 and 58 for the purpose of preventing the complete insertion of the plugs into the respective apertures.
  • the webs 82 around plugs 56 and 58 are integrally connected by means of connecting web 84 which extends webs of the respective plugs.
  • Pull handle 60 which may be in the form of pull ring, is connected to flange-like web 82 surrounding the upper extremity of plug 58 so that an upward pull on ring 60 will first remove plug 58 from aperture 28 and' then plug 56 from aperture 26.
  • Downwardly extending protrusions generally designated 90, serve to maintain the reclosure member 54 distantly spaced from the upper surface of central panel 16 when member 54 is in the resealing position.
  • Sealing layer or patch 50 is bonded to the inner surface of central panel 16 by the thermoplastic adhesive layer 52 in a bonding operation which involves the application of heat and pressure.
  • the adhesive layer 52 may be any suitable adhesive but preferably a thermoplastic copolymer such as an ethelyene acrylic copolymer.
  • the lower portion of plugs 56 and 58 are inserted into their respective apertures and the bottom walls 86 and 88 of plugs 56 and 58 are heat bonded, by means of adhesive layer 52, to sealing patch 50.
  • the lower portion of plugs 56 and 58 are sufficiently small in relation to apertures 26 and 28 so that when initially inserted therein to bond to adhesive layer 52 ample clearance exists whereby minimum contact occurs between the plugs and the .heated end closure.
  • FIG. 8 A slightly modified form of the present invention is depicted in FIG. 8.
  • the reclosure member is substantially the same as above described the only alteration being in the configuration of the aperture peripheries.
  • the peripheries 134 and 136 of apertures 126 and 128 are disposed parallel to central panel 116 rather than downwardly disposed as described above.
  • plugs 156 and 158 are force or compression fitted to the apertures the depending straight walls of the upper portions 164 and 176 are compressed against the peripheral walls 132 and of the respective apertures.
  • An end closure for andeasy opening resealable container which comprises:
