Definitions

  • the present invention relates to containers,v and has particular reference to a hermetically sealed sheet metal reclosure can which may beopened by the simple process of peeling fr om its bodyV a circumferentially extending pull tape to uncover a circumferential slit which partly separates the upper portion of the can from its bottom portion, and then bending the upper portion upwardly to break-the body along a score line to complete its separation.
  • the present invention solves this problem by providing a hermetically sealed can wherein the can body is provided with a precut circumferential slit which extends around the major portion of the can body just below its upper end seam and is sealed by an external sealing tape which can be easily stripped from the body to uncover the slit and'permit ready detachment of the upper portion of the can.
  • a suitable internal reinforcement in the form of a separate or integral collar is disposed inwardly of the slit.
  • the collar provides a. seat for'the detached upper portion of the can so that it can be used as a reclosure after the initial opening of' the can. 4
  • the slit is not extended completely around the body, but is terminated short of each side lof the side seam area so that the body blank remains at all times duringits manufacture a unitary, self-sustaining member which can be handled by thehigh speed automatic equip- ⁇ ment on which cans must bemade in order to be economically competitive with other types of containers.
  • the unslit poriton-offthe body ⁇ between the ends of the slit is, however, scored so that when the tape is removed and the upper portion of the body hinged upwardly around the scored body portion by the ultimate consumer, the flexing of the scored metal causes the body .to break along the score line, thus completing the severance of the upper can portion and permitting it to be completely removed from the lower portion of the can to provide a convenient reclosure.
  • An object ofthe invention is the provision Y of ⁇ an easily opened, hermetically sealed reclosure can.
  • Another object of the invention isthe provision of an easily opened can which can be made on highspeed, automatic equipment.
  • Yet another object ⁇ is the provision of a can which may be'easily opened merely by the removal therefrom of an easily peelable sealing tape and a subsequent upward hinging of the body along a short breakable hinge section.
  • FIGURE l is an elevational View of a can embodying p the concepts of the instant invention
  • Y FIG. 2 is an enlarged fragmentary View of an upper portion of the can of FIG. l, the view showing the side seam area of the can with the sealing tape partially peeled from the can body to initiate the can opening operation
  • FIG. 3 is a plan view of the exterior surface of a flat blank for making the body of the can shown in FIG. l;
  • FIG. 4 is a vertical section, on an enlarged scale, taken substantially along the line 4-4 in FIG. 2;
  • FIG. 5 is a sectional view taken substantially along the line 5-5 in FIG. l;
  • FIG. 6 is a sectional view taken substantially along the line 6 6 in FIG. 3 and FIG. 7 is a view similar to FIG. 4 but illustrating a modified form of the invention.
  • the drawings illustrate a sheet metal can which is formed with a tubular, preferably cylindrical body 10 which is formed from a flat, single-piece, sheet metal blank 12 (see FIG. 3) which has its opposite side edge portions 14, t6 suitably notched and slit to form hook portions 1S, 20 so that when the blank is bent to tubular form to form the body 10, the edge portions 14, 16 may be joined in a soldered side seam 22.
  • the upper and lower portions 24, 26 comprise lap sections and the intermediate portion 28 comprises a lock section wherein the hooks 1S, 20 are reversely folded and interlocked with each other (see FIG. l).
  • top and bottom end members 30, 32 are sealed thereto in hermetic, compound lined double seams 34.
  • the body 10 closely below the top double seam 34 is completely cut through to provide a circumferential slit 36 which extends around the major portion of the body and terminates just short of both sides of the upper lap portion 24 of the soldered side seam 22, as best seen in FIGS. 1 and 2.
  • a circumferential slit 36 which extends around the major portion of the body and terminates just short of both sides of the upper lap portion 24 of the soldered side seam 22, as best seen in FIGS. 1 and 2.
  • the sheet metal of the body 10 including both layers of the lap seam portion 24 is partially cut through to provide a score line 38 which connects the ends'of the slit 36.
  • the slit 36 is covered over and sealed against leakage by a thin, narrow tape 40 which is bonded to the outside ⁇ r surface, of the can body 10 and extends circumferentially around the can and also terminates short of either side of the side seam 22, so that it does not interfere with the side seam forming operations.
  • a thin, narrow tape 40 which is bonded to the outside ⁇ r surface, of the can body 10 and extends circumferentially around the can and also terminates short of either side of the side seam 22, so that it does not interfere with the side seam forming operations.
  • the tape 40 preferably comprises an external layer of aluminum foil 42 and a klayer of a thermoplastic resin 44 which is heat Sealed to the can body 10 to create a hermetic, liquid proof seal around the slit 36.
  • the tape will not peel cleanly resin layers inthe pull tab being heat4 sealed together to has the folvDensity, .923.V
  • vreclosure which, when repositioned in frictional engagementrwith the-collar 50protects the unused portionof wherein two strips of tin plate, each wide, which are adhered to each' other by an interposed layer of this of l inch .per minute and a temperature ot 77 F. indicate a peel Strength ofabout 2.4 lbs. per 3A lineal inch.
  • This ethylenefacrylic acid copolymer preterabl f is ero' inea molten state.
  • the tape 40 is preferably applied to the body blank ⁇ 11.2 ⁇ while the latter is in the fiat, as seeniin FIG.' 3," so
  • thermoplastic resin V4/tof the thermoplastic resin
  • Vthe collar provides a reclosure seat for thelrcan reclosurev which is created inthe can opening operation, lasar/illnowbe l described; Y
  • a tubular sheet metalpb'ody having itsV edgesV seamed together in a longitudinal side seam, Y a circumferential slit Vformed in said body adjacent one end andV extending around amajor'portion thereof, said sl-it terminating closely' Yadjacent both sides ⁇ of said side seam, Y v peelabletape of metallicfoil ,covering and sealing Y said slit andbeing bonded to the ⁇ adjacent portions of said ,can body bya thermoplastic resin' adhesive or low peel resistance, and E Y a collar disposed Within said can body adjacent said slit for supporting said can body in the area thereof on both sides of said slit, said collar extending 1ongitudinally beyond one portion of said can body after it has' been opened along said slit and being engageable with another portion of said can body beyond said slit to provide a reclosure seat therefor.
  • a score line is formed in said can body and extends from one end of said slit to the other end thereof, said score line extending conipletely through all of the layers of said can body in said side seam thereof to provide for complete separation of the portions of said can body on opposite sides of said slit.
