Definitions

  • the present invention relates to easy-opening containers and has particularreference to a container construction wherein a removable plastic strip is incorporated in the top end seam of the container to provide for the complete detachment of the top closure member of the container'without destruction or mutilation of either the container body or the top closure member.
  • the present invention provides an easy opening container construction which avoids all of the disadvantages of these other constructions in that it makes possible a full-open container in which the complete top closure member can be readily detached by the consumer without tools and without any mutilation or tearing of either the container body or the top closure member.
  • the strip is formed of a tough, flexible, tear'resistant thermoplastic resinous material, such as high, medium; or low density polyethylene, polypropylene, or copolymers of ethylene with monomers such as vinyl acetate or ethylacrylate, which is deformable and extensible so that the portion of the strip which is pressed against the container body by the curled edge of the cover member is thinned out in the pressure area which is disposed below but parallel to the top edge of the strip to thus'enhance'the holding power of the strip.
  • a tough, flexible, tear'resistant thermoplastic resinous material such as high, medium; or low density polyethylene, polypropylene, or copolymers of ethylene with monomers such as vinyl acetate or ethylacrylate
  • One end of the strip' is formed into a pull tab which enables the consumer to pull the strip outwardly and away from the end seam.
  • the strip being formed of a tough, extensible plastic, does not tear under the pulling pressure but instead elongates and thins out as it is pulled through the pressure area. By virtue of this thinning of the strip, the strip easily passes through the space between the cover curl and the container body, thereby greatly reducing the holding power of the seam by changing the'connection between the top closure member and the container body to a straight friction seal which the consumer canreadily overcome by manually lifting off the cover member to gain access to the container contents and, if desirable or necessary, subsequently re-establish by replacing the cover member on the body to utilize it as a friction reclosure.
  • An object of the invention of the provision of an easyopening container which is attractive in appearance and can be easily opened without the use of opening tools.
  • Another object is the provision of an easy open container wherein means are provided to permit complete detachment of the top closure member without mutilation of either the body or the top closure member.
  • Another object of the invention is the provision in such a container of a snap-fit reclosure feature.
  • Still another object of the container is the provision of a method of forming such a container.
  • FIG. 1 is a perspective view of a container body having a plastic seam release strip secured in place thereon prior to the application thereto of the top end closure member;
  • FIG. 2 is a perspective view of a completed container embodying the body and strip assembly of FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 showing the upper portion of a container body having a modified form of plastic seam release strip adhered to it;
  • FIG. 4 is an enlarged sectional detail taken substan tially along the line 44 in FIG. 1, and showing addi-' tionally in dot and dash lines a portion of the top closure member in position on the body prior to being seamed thereto;
  • FIG. 5 is an enlarged sectional detail taken substantially along the line 5--5 in FIG. 2;
  • FIG. 6 is a side elevation of the upper portion of th container of FIG. 2 showing the seam release 'strip par tially pulled out of the seam during the container opening operation;
  • FIG. 7 is a sectionaldetail on an enlarged scale taken substantially along the line 7-7 in FIG. 6;
  • FIG. 8 is a vertical sectional detail on an enlarged'scale taken substantially along the line 88 in FIG. I
  • FIG. 2 discloses a container 10 having a tubular body 12 which is formed of a oompressiblematerial such as fibreboard.
  • the body 12 may be'of any suitable type, as for example, a convolutely wound body, :a' lap seam body or a spirally wound body, and may com label plies (not shown) which may be made of metal foil 7 I or plastic film which may or may not be coated with a protectivevarnish or lacquer. While the body 12 is shown as being Cylindrical, it may have any desirable cross sectional configuration. It may also be formed of plastic, glass or metal.
  • the bottom end of the body 12 is closed by means of an imperforate metal bottom closure member 14 which is secured to the body in a seam 16 of any suitable type, while'theupper end of the body 12 is closed by means of an i'rnperforate metal top closure member 18.
  • a thin plastic strip 20 which shall for the purposes of this specification be called a seam release strip, is secured to the upper marginal edge portion of the body 12 by a layer of an adhesive 22 (see FIG. 4) which maybe of any suitable type, such as a pressure sensitive adhesive or a thermoplastic adhesive, and 'which should have low peel resistance characteristics relative to the surface of the body'12 to'which it adheres.
  • the upper edge of the seam release strip 20 is substantially coplanar with the upper edge of the body 12, and the opposed end edges 24, 26 of the strip 20 are disposed in substantially abutting relationship. While these edges may be slightly spaced apart, it is important that they do not overlap each other, at least in the upper portion of the strip, for reasons hereinafter explained.
  • the strip 20 is made of a thermoplastic resin such as high, medium, or low density polyethylene, polypropylene, or copolymers of ethylene with menomers such as vinyl acetate or ethylacrylate, and may vary in thickness from about 3 or 4 mils to 20 mils, depending on the specific container dimensions and requirements and on variables in the other container components.
  • the strip 20 should be deformable .and extensible, and should have a tearrelsistance sufficiently high so that it does not tear during the opening operation. Its surfaces should preferably be smooth and have a relatively low coefficient of friction.
  • the strip may be formed of a single type of plastic or may comprise a lamination of one or more materials which can be selected to tailor the strip to specific container applications. It has been determined that a strip of high density polyethylene and having a thickness of mils is excellent for many container applications.
  • the top closure member 18 is positioned on the body 12 and seamed in place. As shown in dot and dash lines in FIG. 4, the top closure member 18 is formed with a substantially vertical countersink wall 28 which extends into the body and lies inwardly of and in frictional engagement with the inner surface of the marginal top end portion of the body 12. The member 18 is initially formed with on outwardly projecting flange 30 which overlies the top edge of the body 12 and terminates in an inwardly extendin'gopen curl 32.
  • the flange 30 .and ourl 32 of the end 18 are reshaped by means of first and second operation seaming rolls (not shown) in such manner as to bend the flange 30 downwardly and inwardly around the top marginal portion of the body 12 to the configuration shown in FIG. 5.
  • This reshaping operation reforms the initially open curl 32 into a substantially closed curl 34 which presses inwardly against the seam release strip 20 and clamps the strips 20 and the body 12 against the countersink wall 18. It will be understood that the wall 18 is supported by .a seaming chuck (not shown) during the seaming operation.
  • the seaming pressure which is transmitted by the curl 34 causes the generally non-compressible plastic strip 20 to extend and thus results in actual physical thinning of the material of the strip 20 is the annular area of contact 35 where the curl 34 engages the strip 20.
  • the seaming pressure indents a portion of the strip 20 into the fibre body 12 thereby resulting in a compression thinning of a portion 38 0f the body 12 inwardly of the curl 34 and inwardly of the thinned plastic portion 36.
  • the container is filled with' a product (not shown) through its opening bottom end and thereafter closed by seaming the bottom end closure member 14 in place. It will be understood, however, that under some circumstances it may be desirable to fill through the top end of the container. This can readily be accomplished by'rever'sing the order of application of the end closure members, i.e., by first seaming the bottom closure member 14 in place, then filling through the open top end of the container, and then seaming on the top closure member 18.
  • the filling operation may be effected in a factory other than the one in which the strip 20 is applied tothe body 12, thus necessitating shipment of the body 12 with the strip 20 thereon prior to the formation of the seam 40, this presents no problem since the adhesive 22 accurately and positively retains the strip 20 in place on the body 12 until such time as the top end closure member 18 is applied.
  • one end of the strip 20 is formed into a depending pull tab 42 of suitable configuration.
  • the consumer need merely to. grasp the pull tab 42 between a thumb and forefinger and pull it outwardly away from the seam 40 in a substantially clockwise direction, as seen in FIG. 6. Grasping of the pull tab 42 is facilitated by the fact that the adhesive 22 is of a type which has low peel resistance so that the tab 42 can be easily stripped away from the body wall 12 by the use of a finger nail of the consumer. Ifv desired, the adhesive 22 may be omitted from all or a portion of the tab 42 to facilitate its engagement by the fingers.
  • the plastic material from which the strip 20 is 'formed is extensible or elongatable, and thus the pulling pressure has the effect of causing the portion 44 of the strip 20 to elongate and to thin down to substantially the thickness of the gap between the curl 34 and compressed body portion 38 so that it passes downwardly between the curl 34 and the compressed body wall portion 38 and thereby is removed from the end seam 40. Removal of the strip 20 from the seam is facilitated by the fact that the surface of the curl 34 which contacts the strip 20 is rounded and smooth and that the raw edge of the curl 34 is spaced away from the strip 20.
  • the stretching or thinning out of this portion 44 of the strip 20 usually results in its being distorted into a thin, wavy configuration 45 which is indicative of a permanent distortion of the material of the strip 20.
  • the degree of distortion will of course vary with the material from which the strip 20 is made.
  • an open" gap remains 'betweenthecurl -34 and the body 12, as best seen in FIG. 8, so that the securement bet-ween the top closure 18 and the body wall 12 resides in a frictional engagement between the countersink wall 18 of the cover and the inner surface of the upper edge of the body 12.
  • This friction fit can be readily overcome by merely pulling upwardly on the closure member 18 to remove it from the upper edge of the body 12 thereby completing the opening of the container and granting access of: its contents.
  • the closure member 18 may thereafter be replaced on the body 12 to function as a reclosure.
  • the upper edge portion 46 of the body 12 preferably extends radially outwardly to a position where it just slightly overhangs the radially innermost portion of the curl 34.
  • This interference is desirable since it does not appreciably hinder removal of the closure member 18, but does provide a somewhat loose snap fit engagement between the closure member 18 and the body 12 which is very desirable when the former is used as a reclosure.
  • FIG. 3 shows a modification of the pull tab end of the strip 20.
  • this end of the strip 20 is extended beyond the opposite end of the strip to form an overlapping pull tab 47.
  • the upper portion of the strip 20 is cut away along a line 48 which extends downwardly from the top of the strip 20 to a point below the curl 34 and then extends horizontally along the bottom edge of the curl 34.
  • the inside surface of the strip 20 of FIG. 3 is adhered to the body 20 by a low-peel adhesive just as is the strip 20 of FIG. 1.
  • the adhesive is also disposed on the inside surface of the pull tab 47 and adheres it to the underlying portion of the strip 20 so that it does not project outwardly away from the body 20 to a position where it could be inadvertently snagged in such manner as to cause premature partial removal of the strip.
  • a container comprising a tubular b dy, a Seam rele:ase.strip surrounding the outside surface of said body atone, end thereof and extending substantially to the adjacent end edge of said body, and a metal end closure member disposed on the said end of said body, said metalend closure-member having a countersink wall extending along the inner surface of said body and merging into a flange which extends around the adjacent end edge of said body and then along the outer surface of said seam release strip, said flange having at its lower end an annular, smoothly rounded and hollow inwardly projecting curl terminating in an edge spaced from and pointing away from said seam release strip, said curl pressing, at the rounded surface thereof, said seam release strip against said body along an annular pressure area of contact spaced below the said edge of said body to form a clinched end seam where the upper edge portion of said body extends radially outwardly to a position where it overhangs a portiori of said curl, said seam release strip being formed of a tough
  • seam release strip is adhesively secured to the body by an adhesive having low-peel characteristics relative to the body surface to which it is adhered.
  • one end of said seam release strip comprises a pull tab, :and wherein that portion of the seam release strip which is engaged by said flange curl in the pressure area is disposed in non-overlapping relationship.
  • said flange so that it has at its end an annular hollow smoothly rounded inwardly projecting curl, the end edge of said curl facing toward the uncurled 7 8 portion of said flange, and said flange projects gention of said seam release strip is indented into said body erally downwardly, along an annular area spaced below the edge of said body.
