Package for article such as frankfurters

Claim 2

In a package for a product, the combination of: a bag having wall means for confining the product and at least one open end, the region of the bag adjacent said open end being sufficiently flexible to permit twisting thereof, said open end being of sufficient size to permit the product to pass therethrough; said bag receiving the product in a snug fit to provide a support by the product for the bag against inward collapse and to cause a segment of the bag to assume a predetermined cross-sectional configuration; a collar having an opening of sufficient size to permit the product to pass therethrough, said collar being affixed to said region of the bag adjacent said open end; said bag having sufficient length to extend beyond the product in the bag, through the region of the bag adjacent the open end of the bag, a sufficient distance to allow closure of the open end of the bag by twisting of said region of the bag, said region of the bag adjacent the open end being twistable by turning of said collar relative to the product in the bag; and the collar having an opening corresponding to the opening in the bag with the product in the bag and disposed in force fit to the bag to provide a frictional relationship between the bag and the collar in the twisted position of the bag and with the product in the bag.

Claim 3

A combination as defined in claim 1 wherein said means includes means releasable without fracturing of said wall means to allow turning of a said collar to untwist said region of the bag adjacent said opening in a direction to open said open end of the bag.

Claim 4

A combination as defined in claim 1 wherein said opening in said collar is sized to frictionally engage and circumscribe a section of the bag whereby friction between the bag and the collar retains the collar in said position for closing the bag and whereby additional meAns are provided on the bag, with the product in the bag, for retaining the bag in twisted position.

Claim 5

A combination as defined in claim 1 wherein said means includes means for securing the collar to a substantially untwisted section of the bag.

Claim 6

A combination as defined in claim 1 wherein said collar is at least somewhat rigid.

Claim 7

In a package for a product, the combination of: a relatively flexible bag having wall means to confine the product and an opening at one end of said wall means through which the product can pass in a snug fit to provide a support for the bag against inward collapse and to cause a segment of the bag to assume a predetermined cross-sectional configuration; a collar affixed to the wall means at an outer section of the wall means adjacent the opening therein, said collar having an opening therein in general registry with the opening in said wall means, said collar filling over at least a portion of the bag and having force fit with the bag with the product in the bag, said opening in said collar being of sufficient size to permit passage of the product therethrough; said bag being of sufficient length so that when the product is in the bag a particular region of said wall means of said bag lies intermediate the end of the product and said affixation of said collar to said wall means, said particular region of said wall means having sufficient length to close the opening in the wall means by twisting of said particular region of said wall means, said particular region of said wall means being twistable by turning said collar, the twisting of said particular region by the turning of said collar causing said opening to be closed by opposite ends of said wall means; and the collar being provided with an opening corresponding to the opening in the bag, with the product in the bag, to retain the product in the bag by the force of friction when the bag has been twisted.

Claim 8

In a package for a product, the combination of: a relatively flexible bag having wall means to confine the product and an opening at one end of said wall means through which the product can pass in a snug fit to provide a support for the bag against inward collapse and to cause a segment of the bag to assume a predetermined cross-sectional configuration; a collar affixed to the wall means at an outer section of the wall means adjacent the opening therein, said collar having an opening therein in general registry with the opening in said wall means, said collar filling over at least a portion of the bag and having force fit with the bag with the product in the bag, said opening in said collar being of sufficient size to permit passage of the product therethrough; said bag being of sufficient length so that when the product is in the bag a particular region of said wall means of said bag lies intermediate the end of the product and said affixation of said collar to said wall means, said particular region of said wall means having sufficient length to close the opening in the wall means by twisting of said particular region of said wall means, said particular region of said wall means being twistable by turning said collar, the twisting of said particular region by the turning of said collar causing said opening to be closed by opposite ends of said wall means; and the collar being provided with an opening corresponding to the opening in the bag, with the product in the bag, to retain the product in the bag by the force of friction when the bag has been twisted.

Claim 9

A combination as defined in claim 6 wherein said collar is in the form of a ring, said ring being movable generally axially following the turning thereof to a position in which it circumscribes the bag adjacent one end of the product.

Claim 10

A combination as defined in claim 6 wherein said collar is in the form of a sleeve, one end portion of said sleeve being affixed to said wall means at the outer section of the wall means and the other end portion of said sleeve circumscribing a portion of said bag which receives the product therein.

Claim 11

A combination as defined in claim 8 including an end closure for closing said one end portion of said sleeve.

Claim 12

In a package for a product, the combination of: wall means defining a relatively flexible bag having an opening therein for receiving the product; said product providing support for the bag against inward collapse and causing a segment of the bag to assume a predetermined cross-sectional configuration; said product terminating short of the opening in the bag so that a region of the bag projects beyond the end of the product with a sufficient length to provide for a twisting of this region to a closed position; a collar attached to said region of the flexible bag adjacent the opening in the bag, said collar having an opening therein in general registry with the opening in said bag; and said collar being turnable to twist said region of the bag to close said opening in said bag with at least a double layer of the wall means, said collar fitting over at least a section of said bag and being retainable thereby, said collar having a force fit on the bag, with the product in the bag, to retain the region of the bag in the twisted condition by friction.

Claim 13

In a package for a product, the combination of: wall means defining a relatively flexible bag having an opening therein for receiving the product; said product providing support for the bag against inward collapse and causing a segment of the bag to assume a predetermined cross-sectional configuration; said product terminating short of the opening in the bag so that a region of the bag projects beyond the end of the product with a sufficient length to provide for a twisting of this region to a closed position; a collar attached to said region of the flexible bag adjacent the opening in the bag, said collar having an opening therein in general registry with the opening in said bag; and said collar being turnable to twist said region of the bag to close said opening in said bag with at least a double layer of the wall means, said collar fitting over at least a section of said bag and being retainable thereby, said collar having a force fit on the bag, with the product in the bag, to retain the region of the bag in the twisted condition by friction.

Claim 14

A combination as defined in claim 10 wherein said collar extends along the bag at the positions where the product is retained in the bag.

Claim 15

A combination as defined in claim 10 including bonding means for bonding said collar to said bag adjacent the open end of the bag.
