Abstract
Abstract A combined closure and handle for heavy-duty thermoplastic bags constituted by a continuous beaded strip having integral depending spaced skirts. The closure member is extruded from thermoplastic material and includes longitudinally extending and spaced depending skirts; the abutting front and rear wall mouth portions of the bag are received between said depending skirt and sealing is effected therethrough transversely of the bag and across the full width thereof. By punching or similar operation a hand-hold aperture is produced centrally of the bag within the confines of the sealed skirt portions of the closure member and through the enclosed front and rear wall portions of the bag. The present invention relates to heavy-duty thermosplastic bags and to a novel method for closing and sealing the open mouth thereof after the bag will have been filled.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
In combination, a thermoplastic bag-like container comprising front and rear walls united along the side and bottom edges thereof, the aligned free edges of said front and rear walls constituting an open mouth portion, and a combined closure and handle for said bag; said combined closure and handle being constituted by an elongated strip produced from thermoplastic material, said strip having an enlarged longitudinally extending bead along the upper edge thereof and a pair of integral longitudinally extending spaced skirt portions depending from said bead and enclosing therebetween the aligned front and rear mouth wall portions of said thermoplastic bag, said closure strip extending across the complete width of said bag; a heat sealed area extending completely across said closure strip and enclosed bag wall mouth portions, said heat sealed area being located beneath the bead portion and above the bottom edges of said skirt portions; and a longitudinally extending hand-hold aperture produced within the confines of said closure strip and enclosed bag mouth wall portions, the top edge of said hand-hold aperture being in alignment with the bottom edge of the bead on said closure strip and the bottom edge of said aperture being located within the heat sealed area extending across said closure strip and enclosed bag mouth.
Claim 2
Dependent Claim
210 words
In combination, a thermoplastic bag-like container comprising front and rear walls united along the side and bottom edges thereof, the aligned free edges of said front and rear walls constituting an open mouth portion, and a combined closure and handle for said bag; said combined closure and handle being constituted by an elongated strip produced from thermoplastic material, said strip having an enlarged longitudinally extending bead along the upper edge thereof and a pair of integral longitudinally extending spaced skirt portions depending from said bead and enclosing therebetween the aligned front and rear mouth wall portions of said thermoplastic bag, said closure strip extending across the complete width of said bag; a heat sealed area extending completely across said closure strip and enclosed bag wall mouth portions, said heat sealed area being located beneath the bead portion and above the bottom edges of said skirt portions; and a longitudinally extending hand-hold aperture produced within the confines of said closure strip and enclosed bag mouth wall portions, the top edge of said hand-hold aperture being in alignment with the bottom edge of the bead on said closure strip and the bottom edge of said aperture being located within the heat sealed area extending across said closure strip and enclosed bag mouth.
Claim 3
Dependent Claim
34 words
A sealed thermoplastic bag-like container as set forth in claim 1 where said closure strip is extruded from polymeric material and said bag is produced from a compatible polymeric material readily heat sealable therewith.
Claim 4
Dependent Claim
17 words
A sealed thermoplastic bag-like container as set forth in claim 2 where said polymeric material is polyethylene.
Claim 5
Dependent Claim
22 words
A sealed thermoplastic bag-like container as set forth in claim 1 where the longitudinally extending bead on said closure strip is hollow.
Claim 6
Dependent Claim
26 words
A thermoplastic bag-like container as set forth in claim 1 where said closure strip is sealed to only one of said enclosed bag wall mouth portions.
Claim 7
Dependent Claim
121 words
A combined closure and handle in combination with a thermoplastic bag having an open mouth portion, said combined closure and handle comprising an elongated strip produced from thermoplastic material, said strip having an enlarged longitudinally extending bead along the upper edge thereof and a pair of integral longitudinally extending spaced skirt portions depending from said bead, the open mouth portion of said thermoplastic bag being received between said spaced skirt portions, the height of said skirt portions being substantially greater than the diameter of said bead and a longitudinally disposed hand-hold aperture extending through said skirt portions within the confines thereof, said hand-hold aperture also extending through the open mouth portion of said thermoplastic bag received between said spaced skirt portion.
Claim 8
Dependent Claim
121 words
A combined closure and handle in combination with a thermoplastic bag having an open mouth portion, said combined closure and handle comprising an elongated strip produced from thermoplastic material, said strip having an enlarged longitudinally extending bead along the upper edge thereof and a pair of integral longitudinally extending spaced skirt portions depending from said bead, the open mouth portion of said thermoplastic bag being received between said spaced skirt portions, the height of said skirt portions being substantially greater than the diameter of said bead and a longitudinally disposed hand-hold aperture extending through said skirt portions within the confines thereof, said hand-hold aperture also extending through the open mouth portion of said thermoplastic bag received between said spaced skirt portion.
Claim 9
Dependent Claim
24 words
A combined closure and handle in combination with a thermoplastic bag as set forth in claim 6 where said longitudinally exteNding bead is hollow.
