I SUMMARY OF THE INVENTION Polyetheylene plastic bags are increasingly being closed commerciall'yby flat polystyrene bag closures of the Kwik Lok type, thus bringing many advantages in product quality and merchandising'control. It is important that slippage of the bag necks through the closures net plastic, bags. I

be prevented and this is particularly difficult to do with It is an object .of the present invention to provide an improved Kwik Lok type bag closure which will offer a high resistance to slipping on'a'bag neck to which it has been applied.

Itis another object to provide such a bag closure which will effectively resist its sliding on the neck of a plastic net bag to which it has'been applied.

BRIEF DESCRIPTION 'OF THE DRAWINGS DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The invention is'prefer'ably embodied in a clip lO which is shown in full scale in the perspective view of FIG. 1 closing the neck 11 of a net plastic bag 12. To facilitate illustration of the details of the invention FIGS. 2 and 3 inclusive represent enlargements of both preferred and modified forms of the invention by a factor of four.

The clip is preferably about 1 inch square and, as shown, is 0.875 X L094 inch in size. The clip is beveled at the corners l3, and comprises a sheet of stiff but springy'polystyrene plastic with a thickness of 0.0325 inches.

Formed in one edge of the clip is a deep V notch 14 which terminates at its apex in a narrow opening 15, the inner end of which communicates witha bag neck confining aperture 16, upper portions of which are arched upwardly on opposite sides of the opening to divide the material of the clip into two juxtaposed downwardly pointed jaws 17.

The preferred dimensions of clip 10 are shownin 2 In order to apply the clip 10 to the neck 11 of a net plastic bag 12, the bag neck is twisted or bunched in the hand, or by a nachine, and applied forcibly to the V notch 14 of the clip while moving the bag neck lengthwise of its axis so as to deflect the jaws 17 out of the plane of the clip, thereby widening the narrow opening 15 and displacing tongues B and C out of the plane of the clip and away from direct opposition to each other thereby enlarging the spaces between the jaws and between tongues B and C to admit the individual plastic strands of the bag neck 11 through the opening 15 and into the bag neck confining aperture 16. The application of the clip 10 is completed by relaxing pressure on the clip-thereby permitting the jaws 17 and the tongues B anc C to return into the plane of the clip, trapping the bag neck 11 in the aperture 16. v

In this process of forcing the strands of the bag neck -11 into the aperturel6, a large number of individual net openings will be impaled upon the tongues/ X, B and C so that the bag neck will be anchored in place against endwise movement relative to the clip 10, and will thus be permanently closed with the clip positioned on the neck as shown in FIG. 1. Removal of the clip 10 in order to open the bag 12 may be readily accomplished, however, by seizing the clip in one hand and the bag neck in the other and twisting the clip to bend the same about a transverse line, thus flexing the jaws l7 and the tongues B and'C out of the plane of the clip, thereby freeing the bag neck 11 so that it may be pulledfrom the clip.

A modified form of clip 25 is shown in FIG. 3 which is like clip 10 excepting that the aperture 26 thereof is larger than aperture 16 of clip 10 to adapt clip 25 for closing medium size bags.

An important factor in the tenacity with which a net bag neck 11 is gripped by one of the clips '10 or 25 is the surrounding of the aperture'and access opening of theclip with substantial blank areas of the clip body which firmly resist widening of the accessopening 15 or the gap between the pointed ends of tongues B and C while the jaws l7 and the tongues B and C remain in a the plane of the clip which is their normal position of repose and which is the condition in which the'clip 10 is shown in-FIG. 1 after a-bag neck 11 has been forced into aperture 16 by deflecting the jaws l7 and tongues B and C out of the plane of the clip to permit entrance of the bag neck 11 into said aperture. While the respective apertures 16 and 26 of the clips 10 and 25 are de-' signedly made of different sizes to fit different categories of net bags because of variations in the bulk of ma.- terial in different bag sizes which must be received by a clip, the aperture andaccess opening in each of these clips is located exclusively in the upper half of the clip and in the central one-third of said I claim: I 1. ,A clip for closing the neck of a'net upper half.

plastic bag, said I clip comprising: 1

FIG. 2 and will not be repeated here. The aperture 16 Tongues B and C are at the sides of aperture 16 in op- 6 posing relation with each other along a body of flat, rigid but springy sheet plastic-material,

having a bag neck confining aperture formedinternally therein, access to which is provided by an opening in an edge of said body, said openingjdividing 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 onehalf 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 nonnal 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, I

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 2. 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.

3. 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,

4. 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 onehalf 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 aperture providing room to accommodate the entire bulk of a section of the neck of a net plastic I 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,

theoutline 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.
