Definitions

  • the present invention relates to a container which may be manually operable without the need of can opening tools.
  • this invention relates to a container having a manually detachable seam release strip for easy opening of the container.
  • seam release container Containers which are manually openable by the pulling out of a strip from within the end seam attaching an end closure to a container body to thereby loosen this attachment, so called seam release container, are known to the art.
  • An example of such a container is disclosed and described in U.S. Patent No. 3,142,433 in the name of A. E. Balocca.
  • Other examples of such seam release containers could be cited dating back many, many years.
  • each of the prior art containers suffers from a common deficiency which makes them unsuitable for the present day demands of high-speed automated production.
  • This deficiency is the registration and attachment of the seam release strip to the container body by some high-speed automated means so that upon subsequent attachment of the end closure to the container body the seam release or pull-out strip will be properly oriented with respect to the securement of the end closure to the body, i.e., with the pull-out strip secured in the end seam attaching the closure to the body.
  • Balocca patent solves this problem by making the pull-out strip from a portion of the body itself, but weakening the attachment of this pull-out strip to the body. ⁇ Vhile such a construction is reasonably satisfactory, it does not meet the high standards required for consumer acceptance. It has been found that with this construction, the force required to rupture the connection of the pull'out strip to the body and remove the strip from the end seam is often somewhat higher than is considered acceptable to meet consumer demands.
  • Yet another object is to provide a construction for the container which may be readily made on hi h-speed, automated equipment.
  • a further object is to provide a construction for a container which meets the demands for consumer acceptance.
  • a tubular container body is provided with a seam release strip by adhesively securing the strip to the outside wall surface of the body adjacent to an open end of the body.
  • the strip is so positioned on the body that a non-adhered portion thereof,
  • a tab is provided on the strip whereby the user of the can may manually grasp the tab; and, by a pulling action, withdraw the strip from its engagement within the end seam thereby loosening the connection of the end closure to the body for easy separation of the end seam from the body.
  • FIG. 2 is a perspective View similar to FIG. 1 but showing the end closure attached to the body;
  • FIG. 3 is an enlarged fragmentary, sectional View taken substantially along the line 33 of FIG. 2;
  • FIG. 4 is an enlarged fragmentary, elevational View showing the relationship of the elements during removal of the seam release strip
  • FIG. 5 relates to a second embodiment of the present invention and is a perspective view of an open ended can body having a pull-out strip secured in place;
  • FIG. 6 is a perspective view similar to FIG. 5, but showing the end closure secured to the body;
  • FIG. 7 is an enlarged, fragmentary, sectional View taken substantially along the line 7-7 of FIG. 6;
  • FIG. 8 is an enlarged, fragmentary elevational view showing the relationship of the elements during removal of the seam release strip.
  • FIG. 1 a tubular container body It).
  • the body 19 is formed primarily of fibre and preferably by spiral winding. If desired, the fibre of body 10 may have associated therewith other materials such as a fluid-impervious ply of aluminum foil, or a plurality of fibre plies to provide rigidity and strength, or combinations of other materials. It is also within the scope of the present invention that the body 10 be made of materials other than fibre, such as plastic, e.-g. polyethylene, or sheet metal, e.'g. aluminum or tin plate.
  • a seam release strip 14 preferably made of a resilient but tough, i.e. relatively high tensile strength plastic; but it is to be understood that other materials having the necessary resiliency and tensile strength such as metal foilor plastic film-backed paper, may also be used.
  • Metal strip by itself is not practicable because in strip thicknesses needed to provide efficient seam release, metal is too stiff.
  • the strip 14 should have a thickness of at least 3 mils and preferably 10 to 15 mils. Thicknesses less than the minimum would not have sufficient tensile strength and would not provide enough clearance after removal to satisfactorily loosen the closure attachment to the body. The upper limit on strip thickness is governed by cost.
  • the upper edge 16 of the strip 1- is contiguous to the periphery of the open end 12. However, the exact registration of the edge 16 and the body periphery is not absolutely necessary as long as the edge 16 is eventually enclosed within the end seam.
  • the lower edge 13 of the strip 14 is adhesively secured to the body 10 by an adhesive layer or band 29 (FIG. 3) disposed between the inner surface of the strip 14 adjacent to the edge 18 and the outside surface of the body 10. As shown, for ease of application, the adhesive band 2% is peripherally continuous; but, if desired, the adhesive could be in the form of separated spots.
  • the function of the adhesive band 24 is to hold the strip 14 in position on the body 10 until the upper edge 16 is engaged within the end seam, more fully described below.
  • Any suitable adhesive can be used for the band 2%; but a hot melt adhesive is preferred because its quick setting property permits high-speed operation. Suitable construction is not absolutely necessary. In orther words,
  • the length of the strip 14 can be equal to or slightly less than the circumference of the body 16 whereby the end of the tab 22 meets or is just short of the transverse edge 21 (FIG. 4) of the strip 14.
  • the purpose of the tab 22 is to permit initial grasping and pulling of the strip 14; and to this end the tab 22 may be free of any adhesive attachment to the subiacent surface, but preferably is weakly adhered to the subjacent surface.
  • This weak adherence the tab 22' is held in substantial conformity to the contour of the body, i.e. is prevented from extending outwardly from the body thereby minimizing damage to the tab or container during shi ment or handling.
  • This weak adherence is accompiished by providing an adhesive bond 23 between the inside surface of the tab and the subjacent surface adjacent to the free end of the tab. Pulling the tab outwardly subjects this adhesive bond 23 to peel stress under which it ruptures readily.
  • the upper edge of the tab 22 is cut down from the remainder of the upper edge strip 14 to insure against this edge being enclosed within the end scam in a manner more fully described hereinafter.
  • the strip 14 has formed therein a line of weakness 24 extending completely around its periphery but terminating short of the tab 22 by curving downwardly at 25 and merging with the strip lower edge 18.
  • the line of weakness 24 is shown as a score line but it could be of some other construction such as a series of perforations.
  • FIG. 2 illustrates the container body 10 having the pull strip 14 secured thereto as previously described but with a metal end closure generally designated 26 closing the open end 12.
  • the end closure 26 comprises a central panel 28 merging at its periphery with an upstanding countersink wall 30 thence substantially horizontally outwardly over the upper periphery of the can body 10 and thence downwardly in a hemmed skirt 32 to provide a.
  • the body It is first formed.
  • the shaped and scored strip 14 with the band 20 of the adhesive thereon, which adhesive is heat activated, is then secured to the body 10 adjacent to one open end. It is also possible to apply the adhesive to the body 10 rather than to the strip 14. Thereafter, the end closure 26 is attached to the body and strip by means of the end seam 34. Filling of the container thus formed with a product through the open, lower end, i.e., the end of the body 1%) remote from the end closure 25; whereupon a closure is secured to this open end by conventional means to completely close the package.
  • the tab 22 is grasped and pulled outwardly and around the can to tear along the line of weakness 24 and simultaneously disengage the upper edge 16 from the end seam 34. This action is continued until the removable portion or" the strip 14 is completely withdrawn from the end seam 34 thereby loosening the attachment of the closure 26' to the body 10.
  • the closure 26 can then be easily lifted, also manually, ofi the body 1% thereby providing a full opening at one end of the container for removal of the product packed therein.
  • FEGS. 5 through 7 show a second prefered embodiment of the present invention. It differs from the embodiment shown in FIGS. 1 through 8 primarily because the second embodiment has a seam release strip which does not have a line of weakness such as that 24 in the seam release strip 14.
  • the second embodiment involves a simpler construction which permits more economical manufacture without increasing the force required to remove the release strip from the container seam.
  • a tubular container body 110 which can be substantially similar to the one shown in FIGS. 1 through 4 has an open upper end 112 which is surrounded by a seam release strip 114 which can be made of the same material as the strip 14 of the embodiment shown in FIGS. 1 through 4.
  • the upper edge 116 of the strip 114 is positioned close enough to the periphery of the open end 112 so that in the finished container a reasonable width of the strip 114 will be enclosed within the end seam.
  • the lower edge 118 of the strip, that portion not enclosed in the end seam, is adhesively secured to the body by an adhesive layer or band 12% (FIG. 7) disposed between the inner surface of the lower edge 118 and the outside surface of the body 110. As shown, for ease of application, 7
  • the adhesive band 12% is peripherally continuous; but, if desired, the adhesive could be in the form of separated spots.
  • Thefunction of the adhesive band 120 is the same as the function of the adhesive band 20 of the embodiment in FIGS. 1 through 4, i.e., to hold the seam release strip 114 in position on the body 110 until the upper edge 116 is engaged within the end seam.
  • the adhesive 120 must have a low peel strength so that the strip 114 may be manually removed from the container body when the container is opened.
  • the bond should also exhibit relatively high shear strength so that the strip 114 will lie adjacent to the body 110, without accidental separation, until it is desired to open the container.
  • the length of the strip 114 is shown as slightly greater than the circumference (periphery in the case of a noncylindrical body) of the body 110 so that the strip 114 not only extends around the body in adhesive attachment thereto but also overlaps itself a short distance to provide a grasping tab 122. While the overlapping construction is preferred it is not absolutely necessary. In other words,- the length of the strip 114 could be equal to or slightly less than the circumference of the body 110 whereby the end of the tab 122 meets or is just short of the transverse edge 123 (FIG. 8) of the strip 114. j
  • the tab 122 is to permit initial grasping and pulling of the strip 114.
  • the tab 122 may be free of any adhesive attachment to the subjacent surface, but preferably is weakly adhered to the subjacent surface. By this weak adherence, the tab 122 is held substantially in conformity to the contour of the body, i.e. is'
  • FIGS. 6 and 7 illustrate the container body 110 having a pull strip 114 secured thereto as previously described, but with a metal end closure, generally designated 126, closing the open end 112.
  • the end closure 126 comprises a central panel 128 merging at its periphery with an upstanding countersink wall 130 thence substantially horizontaily outwardly over the upper periphery of the can body and thence downwardly in a hemmed skirt 132 to provide a substantially U-shaped channel 133.
  • the upper edge 135 and therefore the entire tab 122 is outside the end seam 134 to permit the tab 122 to remain free for easy grasping.
  • a thin tape having adhesive on both sides and an easily peelable adhesive on at least one side is placed between the pull strip 114 and the body 110 to adhere the strip 114 to the body 110.
  • the body 110 is first formed and is externally coated with a varnish 121.
  • the shaped strip 114, with the band 120 of adhesive thereon, which adhesive is heat activated, is then secured to the body 110 adjacent to one open end. It is also possible to apply the adhesive to the body 110 rather than the strip 114. Thereafter the end closure 126 is attached to the body 110 and the strip 114 by means of the end seam 134.
  • the container shown in FIGS. 5 through 8 can be filled in the same manner as the container shown in FIGS. 1 through 4, that is through the end which is remote from the end closure 126; whereupon a closure is secured to this lower open end by conventional means to completely close the package.
  • the end closure remote from the seam release strip is secured on the body before the container is filled but the seam release strip may be placed on the body before or after the filling operation.
  • the open end is fitted with an end closure which is joined to the body by a seam which encloses the seam release strip.
  • the tab 122 is grasped and pulled outwardly around the can to peel along the interface of the strip 114 and the body 110 and simultaneously disengage the upper edge 116 from the end seam 134. This action is continued until the portion of the strip 114 within the end seam is completely withdrawn therefrom, thereby loosening the attachment of the closure 126 to the body 110. The closure 126 can then be easily lifted, also manually, off the body 110 thereby providing a full opening of the container for removal of the product therein.
  • 5 through 8 are especially advantageous when the product is a frozen juice concentrate since no end closure is left on the body to act as an obstruction to the removal of the substantially solid block of product.
  • the opening feature advantageous, but also the loose fit between the closure and the body, after opening, permits ready reclosure during the useful life of the container.
  • a non-tacky or sealing compound such as plastisol, is placed on the countersink wall to form a seal between the wall and the end of the body.
  • a tubular container body open at one end and adapted to have a rigid closure of relatively hard material secured to said open end by means of a single seam;
