  This invention improves the clip concerning invention of patent document 1, and makes it a subject to provide a clip which is easier to use and applicable also to a wider use.

The invention of claim 1 is a solution to the problem.
A receiving portion; a fitting portion that can be detachably fitted to the receiving portion; and a bendable hinge portion that connects one end portion of the receiving portion and one end portion of the fitting portion. , A clip that can be bent at the hinge portion and sandwiched between the receiving portion and the fitting portion to fix the thin object,
The receiving part has a first bottom part and two first outer walls suspended from both side edges of the first bottom part;
A groove portion is formed in the lengthwise direction inside the receiving portion, and the groove portion is formed by two internal walls that are suspended from the inner surface of the first bottom portion at an interval in the width direction. And
A plurality of ribs in which the two inner walls forming the groove portion are arranged at intervals in the lengthwise direction between the two first outer walls, the two inner walls, and the two inner walls at the lower part thereof Connected with
The fitting portion has a second bottom portion and two outer walls suspended from both side edges of the second bottom portion;
A leg portion is formed in the lengthwise direction inside the fitting portion, and the leg portion is suspended from the inner surface of the second bottom portion, spaced in the width direction and formed in the length direction. Formed by two internal walls,
The two inner walls forming the legs are a plurality of ribs arranged at intervals in the length direction between the two outer walls, the two inner walls, and the two inner walls at the lower part thereof. Are connected,
A clip is provided, wherein the height (h ₁ ) of the leg is adjusted to be higher than the height (H ₁ ) from the inner surface of the second bottom to the top of the second outer wall.

  The clip of the present invention is closed in a state where a thin object is sandwiched between the receiving part and the fitting part and fixed to the thin object according to various purposes.

  The thin material referred to in the present invention is a paper, cloth or plastic bag, paper, cloth, plastic sheet or a bundle of a plurality of them, a tube product (cosmetic cream, toothpaste, adhesive, various pastes or gels) Any product may be used as long as it can be sandwiched between products in a form in which a flexible food or the like is filled in a flexible tube.

  Although the clip of the present invention has an elongated shape, the dimensional ratio of width to length is not particularly limited and can be appropriately set according to the purpose. The clip of the present invention can have a length that is sufficiently longer than a width (for example, a length that is at least five times the width).

  The method for connecting the receiving portion and the fitting portion in the clip of the present invention and the method for connecting the two rims in the clip of Patent Document 1 are basically the same.

  However, in the present invention, the ribs are all formed inside, but the structure of the clip of the cited document 1 is different in that the rib corresponding to the fitting portion of the present invention is formed on the outer surface.

  In the clip of the cited document 1, since the rib is formed on the outer surface, the height of the portion corresponding to the leg portion of the present invention must be lowered.

  On the other hand, in the clip of the present invention, since the rib is formed only inside, the height of the two inner walls forming the leg portion (height of the leg portion) can be increased. Therefore, compared to the case where the height of the portion corresponding to the inner wall is low as in the cited document 1, when the thin object is sandwiched, the two inner walls (leg portions) are arranged in the inner direction so as to reduce the distance between them. It becomes easier to bend and deform, so that it can be sandwiched with a smaller force, and a thicker one can be sandwiched.

  Moreover, since the height of the two inner walls forming the leg portion (the height of the leg portion) can be increased, by setting the insertion depth of the leg portion into the groove portion, It is also possible to increase the binding force.

  The means for fixing the receiving portion and the fitting portion is not particularly limited, and can be the same as the locking mechanism described in the cited document 1, for example.

According to a second aspect of the invention, as another means for solving the problems, the ratio of the height of the legs (h ₁₎ and height from the second bottom inner surface to the top of the second outer wall (H ₁₎ ( The clip according to claim 1, wherein h ₁ / H ₁ ) has a relationship of 1.2 to 2.0.

  In the clip of the present invention, since the rib for reinforcing the groove and the leg is formed on the inner side, the maximum height of the leg can be made larger than that of the clip of the cited document 1. For this reason, the maximum height of the leg portion can be adjusted in a wide range, and the depth of the groove portion can be adjusted in a wide range accordingly.

  In another aspect of the present invention, a magnet is attached to at least one of the outer surface of the first bottom portion of the receiving portion and the outer surface of the second bottom portion of the fitting portion. Or the clip of 2 description is provided.

  When the magnet is attached in this manner, the thin object can be sandwiched between the clips of the present invention, and then attached to a metal wall surface (for example, a refrigerator) in a detachable manner. Moreover, by detachably attaching the clip to the metal wall surface, the location becomes clear and loss can be prevented.

  In another aspect of the present invention, the pressure-sensitive adhesive portion is formed on at least one of the outer surface of the first bottom portion of the receiving portion and the outer surface of the second bottom portion of the fitting portion. A clip according to 1 or 2 is provided.

  When the adhesive portion is attached in this manner, the clip can be fixed to the wall surface after the thin object is sandwiched between the clips of the present invention. When the adhesive portion is provided, a release paper is pasted on the adhesive surface when not used. Further, by fixing the clip to the wall surface, the location becomes clear and loss can be prevented.

  In another aspect of the invention, the outer surface of the first bottom portion of the receiving portion and the outer surface of the second bottom portion of the fitting portion may be different from other outer surfaces as another means for solving the problem. 3. The clip according to claim 1, wherein the area is set to be large, and at least one of a magnet, an adhesive portion, and a screwing hole is provided on a larger outer surface side. .

  Thus, the fixing strength with respect to a wall surface etc. is raised more by setting any one outer surface so that an area may become larger than another outer surface.

  In another aspect of the present invention, the outer surface is smooth and has no irregularities when the thin part is sandwiched and fixed between the receiving part and the fitting part. A clip according to any one of claims 1 to 5 is provided.

  Since the clip of the cited document 1 has ribs on the outer surface, it cannot be made smooth. However, since the clip of the present invention has ribs inside, the outer surface can be made smooth. For this reason, by attaching various figures and patterns to the outer surface of the clip, it is possible to increase the commercial value and to easily print advertising characters and the like.

  The clip of the present invention can be fixed by inserting a thicker one with a smaller force than the clip of the cited document 1.

  A groove portion 21 is formed in the length direction inside the receiving portion 20 surrounded by the first bottom portion 27 and the two first outer walls 22 and 23. The groove portion 21 is formed by an inner surface 27a of the first bottom portion 27 with an interval in the width direction and two inner walls 24, 25 suspended from the inner surface 27a. As shown in FIG. 4A, the inner surfaces of the two inner walls 24 and 25 have inclined surfaces 24a and 25a in which the distance between the tip portions of the inner walls 24 and 25 increases. The groove portion 21 is continuously formed over substantially the entire portion from one end side to the other end side of the receiving portion 20.

  The two inner walls 24 and 25 forming the groove portion 21 are arranged at a distance in the length direction between the two first outer walls 22 and 23 and the two inner walls 24 and 25 in the lower portion thereof. The plurality of ribs 26a are connected to the two inner walls 24, 25 by a plurality of ribs 26b arranged at intervals in the length direction. The inner walls 24 and 25 are reinforced by the plurality of ribs 26a and 26b. In FIG. 4A, the height of the rib 26a is higher than that of the rib 26b. However, the rib 26a and the rib 26b may have the same height, or the height of the rib 26a may be higher than the height of the rib 26b. It may be low.

  The reinforcing effect of the inner walls 24, 25 by the plurality of ribs 26a, 26b is improved by increasing the number of the ribs 26a, 26b and increasing the height of the ribs 26. For this reason, when it is intended to enhance the reinforcing effect in accordance with the purpose of use of the clip 10 or the like, the height of the rib 26a is set to the height of the two first outer walls 22 and 23 as shown in FIG. Can be as high as the height. Further, the height of the rib 26a can be set to an arbitrary height between the heights of the ribs 26a in FIGS. 4 (a) and 6 (a).

  The fitting portion 30 has a second bottom portion 37 and two outer walls 32 and 33 suspended from both side edges of the second bottom portion 37, and has a hinge portion 12 on one end side in the length direction. On the other end side in the vertical direction, there is a lock portion 13 and a projection portion 16 coupled to the attachment / detachment itself.

  A leg portion 31 is formed in the length direction inside the fitting portion 30 surrounded by the second bottom portion 37 and the two second outer walls 32 and 33. The leg portion 31 is formed by two inner walls 34 and 35 that are suspended from the inner surface 37a of the second bottom portion 37 with an interval in the width direction. The outer surfaces of the two inner walls 34 and 35 have inclined surfaces 34a and 35a as shown in FIG. The leg portion 31 is continuously formed to have the same length as the groove portion 21 over almost the entire portion from one end side to the other end side of the leg portion 30.

The two inner walls 34, 35 forming the leg 31 are arranged between the two second outer walls 32, 33 and the two inner walls 34, 35 and between the two inner walls 34, 35 at the lower part thereof. Are connected by a plurality of ribs 36 arranged at intervals in the length direction. The inner walls 34 and 35 are reinforced by the plurality of ribs 36. The interval w ₁ between the tips of the two inner walls 34 and 35 is a fixed interval when not in use. In FIG. 4B, the height of the rib 36 is uniform, but the rib 36 between the two second outer walls 32, 33 and the two inner walls 34, 35, and between the two inner walls 34, 35. The height of the rib 36 may be varied.

  The effect of reinforcing the inner walls 34 and 35 by the plurality of ribs 36 is improved by increasing the number of the ribs 36 and increasing the height of the ribs 36. For this reason, when it is intended to enhance the reinforcing effect depending on the purpose of use of the clip 10 or the like, the height of the rib 36 is set to the height of the two first outer walls 32 and 33 as shown in FIG. Can be as high as the height. Further, the height of the rib 36 can be set to an arbitrary height between the heights of the ribs 36 in FIG. 4B and FIG. 6B.

The height of the legs 31 and _{(h 1),} the ratio of the height of the second bottom inner surface 37a to the second outer wall of the top portion _{32a, 33a (H 1) (} h 1 / H 1) is 1.2 to 2 0.0 relationship is preferably satisfied.

By increasing the ratio of h ₁ / H ₁ described above, the protruding height h _{2 of the} leg portion 31 (the height of the portion where the leg portion 31 protrudes above the top portions 32a and 33a) can be increased. . The protruding height h ₂ of the leg portion 31 and the depth h ₃ of the groove portion 21 have a relationship of h ₃ ≧ h ₂ . The depth _{h 3} of the groove 21 is adjusted by the height of the rib 26b.

  Next, the usage method of the clip 10 of this invention is demonstrated. First, a thin object (for example, the mouth portion of the opened bag) is placed on the receiving portion 20 shown in FIG. Next, the fitting part 30 is bent in the hinge part 12, and the projection part 16 is fitted and fixed to the lock part 13 (the state shown in FIG. 2 is obtained except that there is no thin object).

The relationship among the receiving part 20, the fitting part 30, and the thin object 50 at this time is shown in FIG. As shown in FIG. 5 or FIG. 7, when the thin object 50 is sandwiched, the tips of the legs 31 (two inner walls 34, 35) are bent inward so as to approach each other (FIG. 4B). ) Or the distance w ₁ between the tip portions is smaller than the state of FIG. 6B). When the thickness of the thin object 50 is partially different, the interval w ₁ between the two inner walls 34 and 35 is bent and deformed so as to be partially different.

In the clip 10, since the rib 36 is formed inside, the height (h ₁ ) of the two inner walls 34 and 35 of the leg portion 31 can be increased (that is, the protruding height h of the leg portion 31). ₂ can be made high), and this facilitates bending of the tip as shown in the figure. For this reason, compared with the past (the clip of the cited document 1), the thin object 50 having a larger thickness can be sandwiched with a smaller force.

  When the thin object 50 is removed from the clip 10, the coupling between the lock portion 13 and the projection portion 16 is released, and the fitting portion 30 is separated from the receiving portion 20, so that the state shown in FIG. In addition, as shown in FIG. 8, the lock part 13 and the protrusion part 16 can be made the same as the lock mechanism in the clip of the cited reference 1. The lock portion 13 is made of an elastic member, and has a lock portion main body 14 and a claw portion 15. The protrusion 16 is a protrusion protruding from the end of the fitting portion 30. When the fitting portion 30 is fitted into the receiving portion 20, the projection portion 16 pushes the claw portion 15, so that the main body 14 is deformed so as to be warped, and the projection portion 16 enters under the claw portion 15. Thereafter, since the main body 14 is restored to the shape before deformation, the protrusion 16 is pressed and held by the claw 15. When the coupling between the lock portion 13 and the projection portion 16 is released, the projection portion 16 pressed by the claw portion 15 is released by pressing with a finger so that the main body 14 is warped.

  Next, a clip according to another embodiment will be described with reference to FIGS. 9 and 10 are cross-sectional views in the width direction in the state shown in FIG. 2 of the clip according to another embodiment (a cross-sectional view at a portion where no rib is provided).

When the clip 10 in the form of FIG. 9 has the magnet 41, a thin object can be sandwiched between the clips 10 and then detachably held on a metal surface such as a side surface of the refrigerator. Moreover, when the clip 10 of the form of FIG. 9 has the adhesion part 41, after fixing the clip 10 to a desired wall surface etc., a desired thin object can be inserted | pinched. Furthermore, since the clip can be held on the wall surface or the like by having the magnet or the adhesive portion, the location of the clip becomes clear and loss can be prevented.

  In the form of FIG. 10, the outer surface 27 b of the first bottom portion 27 of the receiving portion 20 is larger than the outer surface 37 b of the second bottom portion 37. A magnet 41 (or an adhesive portion 41 covered with release paper) is embedded on the outer surface 27b side of the first bottom portion 27, and a plurality of screw holes 43 are formed in the remaining portion. Yes. In the form of FIG. 10, since the area of the magnet 41 or the adhesion part 41 can be enlarged compared with the form of FIG. 9, the retention strength to a metal surface, another wall surface, etc. is raised more. Furthermore, since it has the hole 43 for screwing, by using together with the adhesion part 41, the adhering force to a wall surface etc. is raised more.
