Abstract
Abstract A clip about 1 inch square of flat springy plastic, such as 0.032 inch guage polystyrene, having an internal bag neck confining aperture, access to which is provided by a narrow opening in an edge of the clip dividing the clip on opposite sides of said opening into a pair of flexible jaws. The opening edges flare outwardly to guide the bunched bag neck into the inner narrow part of the opening. A pointed tongue formed integral with the clip extends into said aperture to engage the bag neck and resist slippage of said bag neck through said aperture. A multiple of said tongues may be provided, in which case a pair of tongues may extend into said aperture into a juxtaposed relationship on a transverse axis. A third tongue may be provided pointed toward and co-axially aligned with said narrow opening.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
340 words
A clip for closing the neck of a net plastic bag, said clip comprising: a body of flat, rigid but springy sheet plastic material, having a bag neck confining aperture formed internally therein, access to which is provided by an opening in an edge of said body, said opening dividing the body material on opposite sides thereof into a pair of inwardly pointed flexible jaws, said aperture and access opening being co-axial lengthwise with said body and confined exclusively to an area at one end thereof which is about one-half the length of said body and about one-third the width of said body, the blank lateral and end portions of said body firmly inhibiting expansion of said jaws while reposing in the plane of said body, said aperture providing room to accommodate the entire bulk of a section of the neck of a net plAstic bag of a given size, and be approximately filled by said bulk, after said clip has been flexed out of said plane to enlarge the gap between the points of said jaws and to admit said neck through said opening and then is allowed to resume its flat condition of repose, the outline of said aperture being shaped to provide two sharply pointed tongues each of which is formed symmetrically about a single transverse axis which is common to said tongues and normal to the lengthwise axis of said body, said tongues extending inwardly in direct, co-axial transverse opposition to each other thereby effectively biting into said bag neck and resisting its escape from said clip, said tongues dividing said aperture into substantially equal upper and lower portions, the edges of said tongues being straight, diverging from the tongue points at angles of approximately 90* and continuing straight approximately to the upper and lower lateral extremities of said aperture, the outline of the lower portion of said aperture being shaped to provide a third sharply pointed tongue formed symmetrically with the axis of said entrance opening whereby said aperture has the shape of an X.
Claim 2
Dependent Claim
340 words
A clip for closing the neck of a net plastic bag, said clip comprising: a body of flat, rigid but springy sheet plastic material, having a bag neck confining aperture formed internally therein, access to which is provided by an opening in an edge of said body, said opening dividing the body material on opposite sides thereof into a pair of inwardly pointed flexible jaws, said aperture and access opening being co-axial lengthwise with said body and confined exclusively to an area at one end thereof which is about one-half the length of said body and about one-third the width of said body, the blank lateral and end portions of said body firmly inhibiting expansion of said jaws while reposing in the plane of said body, said aperture providing room to accommodate the entire bulk of a section of the neck of a net plAstic bag of a given size, and be approximately filled by said bulk, after said clip has been flexed out of said plane to enlarge the gap between the points of said jaws and to admit said neck through said opening and then is allowed to resume its flat condition of repose, the outline of said aperture being shaped to provide two sharply pointed tongues each of which is formed symmetrically about a single transverse axis which is common to said tongues and normal to the lengthwise axis of said body, said tongues extending inwardly in direct, co-axial transverse opposition to each other thereby effectively biting into said bag neck and resisting its escape from said clip, said tongues dividing said aperture into substantially equal upper and lower portions, the edges of said tongues being straight, diverging from the tongue points at angles of approximately 90* and continuing straight approximately to the upper and lower lateral extremities of said aperture, the outline of the lower portion of said aperture being shaped to provide a third sharply pointed tongue formed symmetrically with the axis of said entrance opening whereby said aperture has the shape of an X.
Claim 3
Dependent Claim
61 words
A clip as recited in claim 1 wherein the portions of said aperture forming the configuration of an X comprise upper ''''arms'''' and lower ''''legs'''', and wherein said aperture is attenuated lengthwise to offset said legs downwardly from alignment with said arms, thereby substantially decreasing the gap between the points of said lateral tongues without decreasing the area of said aperture.
Claim 4
Dependent Claim
25 words
A clip as recited in claim 1 wherein the space between the juxtaposed points of said side tongues is approximately four hundredths of an inch.
Claim 5
Dependent Claim
285 words
A clip for closing the neck of a net plastic bag, said clip comprising: a body of flat, rigid but springy sheet plastic material, having a bag neck confining aperture formed internally therein, access to which is provided by an opening in an edge of said body, said opening dividing the body material on opposite sides thereof into a pair of inwardly pointed flexible jaws, said aperture and access opening being co-axial lengthwise with said body and confined exclusively to an area at one end thereof which is about one-half the length of said body and about one-third the width of said body, the blank lateral and end portions of said body firmly inhibiting expansion of said jaws while reposing in the plane of said body, said aperture providing room to accommodate the entire bulk of a section of the neck of a net plastic bag of a given size, and be approximately filled by said bulk, after said clip has been flexed out of said plane to enlarge the gap between the points of said jaws and to admit said neck through said opening and then is allowed to resume its flat condition of repose, the outline of said aperture being shaped to provide two sharply pointed tongues each of which is formed symmetrically about a single transverse axis of said body, said tongues extending inwardly in direct, co-axial transverse opposition to each other thereby effectively biting into said bag neck and resisting its escape from said clip, the outline of the lower portion of said aperture being shaped to provide a third sharply pointed tongue formed symmetrically with the axis of said entrance opening whereby said aperture has the shape of an X.
Claim 6

A clip for closing the neck of a net plastic bag, said clip comprising: a body of flat, rigid but springy sheet plastic material, having a bag neck confining aperture formed internally therein, access to which is provided by an opening in an edge of said body, said opening dividing the body material on opposite sides thereof into a pair of inwardly pointed flexible jaws, said aperture and access opening being co-axial lengthwise with said body and confined exclusively to an area at one end thereof which is about one-half the length of said body and about one-third the width of said body, the blank lateral and end portions of said body firmly inhibiting expansion of said jaws while reposing in the plane of said body, said aperture providing room to accommodate the entire bulk of a section of the neck of a net plastic bag of a given size, and be approximately filled by said bulk, after said clip has been flexed out of said plane to enlarge the gap between the points of said jaws and to admit said neck through said opening and then is allowed to resume its flat condition of repose, the outline of said aperture being shaped to provide two sharply pointed tongues each of which is formed symmetrically about a single transverse axis of said body, said tongues extending inwardly in direct, co-axial transverse opposition to each other thereby effectively biting into said bag neck and resisting its escape from said clip, the outline of the lower portion of said aperture being shaped to provide a third sharply pointed tongue formed symmetrically with the axis of said entrance opening whereby said aperture has the shape of an X.
