  The subject of this invention is making it possible to clamp a to-be-clamped object reliably.

  According to the first aspect of the present invention, the first supporting piece and the second supporting piece that are opposed to each other extend from both ends of the connecting portion in the same direction, and the first holding portion and the second supporting piece provided on the distal end side of the first supporting piece. A clip that allows a sandwiched object to be sandwiched between a second sandwiching portion provided on the distal end side so as to be sandwiched, and at least a part of at least one of the first sandwiching portion and the second sandwiching portion includes the sandwiching portion. The support piece is made of a material having a higher coefficient of friction than the constituent material of the support piece.

  FIG. 1 shows an object to be clamped 3 which is a folding sealing part of a plastic sheet (or paper) opening sheet 2 forming an opening of a bag 1 such as a gusset bag. is there. As shown in FIG. 2, the clip 10 extends the first support piece 11 and the second support piece 12 facing each other from both ends of the connecting portion 13 in the same downward direction (possible upward, lateral direction, etc.) to provide a first support. The object to be clamped 3 is inserted between the first clamping part 21 provided on the distal end side of the piece 11 and the second clamping part 22 provided on the distal end side of the second support piece 12 as shown in FIG. .

  In addition, the clip 10 forms a convex portion 21 </ b> A that extends over the entire length along the lateral direction (direction perpendicular to the vertical direction) of the first sandwiching portion 21, and the projecting portion 22 </ b> A across the entire length along the lateral direction of the second sandwiching portion 22. The two convex portions 21A and 22A are opposed to each other through a minute gap, or the two convex portions 21A and 22A are brought into close contact with each other.

  The clip 10 has a first support piece 11 and a second support piece 12 in which the portions on the lower end side of the first holding part 21 and the second holding part 22 are expanded downward toward each other. It is set as the lower guide part 31 and 32 for insertion for (FIG. 2, FIG. 3).

  The clip 10 is a sandwiched object in which the lateral sides of the first sandwiching portion 21 and the second sandwiching portion 22 in the first support piece 11 and the second support piece 12 are expanded laterally outward. 3 is a lateral guide portion 41, 42 for insertion (FIG. 2).

  In the clip 10, the entirety of the first support piece 11, the second support piece 12, and the connecting portion 13 is an integrally molded plastic. As the plastic, polycarbonate, polypropylene, polyethylene terephthalate, or the like can be used. However, you may comprise the 1st support piece 11, the 2nd support piece 12, and the whole connection part 13 with metals, such as stainless steel.

  The clip 10 has at least a part of one of the first clamping part 21 and the second clamping part 22, and in this embodiment, at least a part of the first clamping part 21 has a higher coefficient of friction than the constituent material of the first support piece 11. It is comprised with material, for example, rubber-type material. In this embodiment, only a part of the intermediate portion excluding both side portions of the entire length of the first sandwiching portion 21 along the lateral direction is made of a rubber material, and the first support piece 11, the second support piece 12, and the communication It is assumed that a rubber material is molded in two colors on the constituent plastic of the portion 13.

  Therefore, in the clip 10, the object 3 to be sandwiched is inserted between the first sandwiching portion 21 and the second sandwiching portion 22 from the lower guide portions 31 and 32 (or the lateral guide portions 41 and 42). The first holding portion 11 and the second supporting piece 12 are opened by being elastically bent and deformed at the base portion to the connecting portion 13, and the elastic restoring force of the first supporting piece 11 and the second supporting piece 12 is used as a holding force. The object to be sandwiched 3 is sandwiched between the convex portion 21 </ b> A of 21 and the convex portion 22 </ b> A of the second sandwiching portion 22.

According to the present embodiment, the following operational effects can be obtained.
(a) The clip 10 includes at least a part of the first sandwiching portion 21 made of a rubber material, so that the thickness of the sandwiched object 3 is thin, the sandwiched article 3 is a plastic sheet having a low friction coefficient, or Even when the sheet is made of a sheet surface-treated with a low friction coefficient plastic or the like, the first sandwiching portion 21 is attached to the sandwiched object 3 that is once inserted and sandwiched between the first sandwiching portion 21 and the second sandwiching portion 22. It exerts high frictional force on the rubber material. As a result, the clip 10 securely holds the object 3 without falling off the object 3.

  (b) Since the clip 10 includes the lower guide portions 31 and 32 for insertion, the object 3 can be easily inserted from above the object 3.

  (c) Since the clip 10 includes the lateral guide portions 41 and 42 for insertion, the object to be clamped 3 can be easily inserted from the side of the object to be clamped 3.

  The size of the clip 10 is such that the lateral length L is 30 to 100 mm, the height H is 10 to 30 mm, and the width t is 5 to 15 mm.

  As a rubber material which comprises the 1st clamping part 21, what makes the rubber hardness by a type A durometer measuring machine in the range of 30-80 is suitable.

  The clip 10 of FIG. 4 is different from the clip 10 of FIGS. 1 to 3 in that a recess 51 is provided over the entire length of the first clamping part 21 in the lateral direction, and the recess 51 and the second clamping part of the first clamping part 21 are provided. 22 convex portions 22A are opposed to each other through a minute gap, or both concave portions 51 and convex portions 22A are engaged in close contact, and the concave portions 51 of the first sandwiching portion 21 and the second sandwiching portions 22 The object 3 to be sandwiched is more securely sandwiched between the convex portions 22A.

  The clip 10 of FIG. 5 is different from the clip 10 of FIGS. 1 to 3 in that the convex portion 21A of the first clamping part 21 is removed and the surface of the first clamping part 21 is made substantially planar. The surface of the first sandwiching portion 21 and the convex portion 22A of the second sandwiching portion 22 are brought into close contact with each other through a minute gap, and the object 3 is sandwiched between them.
