Description

  The present invention relates to a mudler for stirring a fluid such as a beverage, and more particularly to a mudler with a clip provided with a clip capable of pinching (that is, holding and holding) an object to be pinched.

  This type of mudler with a clip is provided with a clip having a light elasticity for holding an open end (object to be clamped) of a container such as a cup on the upper part of a main body formed in a rod shape (for example, a patent Reference 1), or a portion that is folded back so that the tip of the knob formed in the shape of a rod follows the knob, as a clip for sandwiching the opening end of the container (for example, Patent Document 2) See).

  In each of the above conventional muddlers with clips, the rod-shaped main body and the knob are configured so that the rod-shaped clips are also placed, so that the open end of the container is pinched in a point contact or line contact state. become. For this reason, there existed a problem that it was not in the state stably hold | maintained at the opening edge part of the container.

  In order to solve such problems, a tuning fork-like part connected at the top, and a gap slightly smaller than the thickness of the tuning-fork-like part and the rim of the container (paper cup) (opening end, sandwiched object) are maintained. A clip-type mudler has been developed in which a knob is formed by a tongue-like portion bent and attached along the outer wall of the container, and a notch having at least a lateral groove component is provided on the inner side of the tongue-like portion. (For example, refer to claim 2 in FIG. 4 and FIG. 4).

  According to the improved mudler with a clip, the mouth of the container can be sandwiched in a two-line one-surface state by the tuning fork-like part and the tongue-like part, so that it is stably held on the mouth of the container. There is an advantage of being in a state of being.

  However, in the improved mudler with clip shown in Patent Document 3, a gap slightly smaller than the thickness of the lip of the container is formed between the tuning fork portion and the tongue-like portion. There is a problem that a thinner object cannot be sandwiched between the tuning fork-like portion and the tongue piece-like portion.

  In addition, the notch will form a concave portion and a convex portion in the tongue-like portion, and since the convex portion is formed by the notch, the thickness is larger than the thickness of the original tongue-like portion. There is a disadvantage that it cannot be formed to a height of 5 mm. For this reason, it is impossible to effectively prevent the lip of the container inserted between the tuning fork-shaped portion and the tongue-shaped portion from coming out of the portion by the convex portion. That is, since only a convex part with a low height can be obtained, there is a problem that the convex part cannot sufficiently prevent the lip of the container from coming out between the tuning fork part and the tongue piece part. In addition, since the portion having the notches in the tongue-like portion becomes thinner than the original thickness, there is a problem that a portion having low strength is generated in the tongue-like portion.

  The present invention has been made in view of the above circumstances, and even a thin object can be stably held by the knob and the holding part, and the object to be clamped comes out from between the knob and the holding part. It is an object of the present invention to provide a mudler with a clip that can sufficiently prevent the occurrence of a low-strength portion and prevent a low-strength portion from being generated in a sandwiching portion.

In order to solve the above-mentioned problem, the invention according to claim 1 is a mudler with a clip having a mixing portion on a distal end side, a knob portion on a proximal end side, and a clip on the knob portion. The knob portion is formed in a plate shape, and the clip has a fulcrum portion connected to the knob portion on one surface side of the knob portion, and from the fulcrum portion to the knob portion. And has a pinching portion extending to the tip side with a space therebetween, and the knob portion has a hole that penetrates in a thickness direction at a portion corresponding to the pinching portion, and A second hole penetrating in the thickness direction is formed in a portion opposite to the hole with a portion corresponding to the fulcrum part of the clip, and the holding part reaches at least the hole. A protruding protrusion is provided.

  A second aspect of the invention is characterized in that, in the invention of the first aspect, a plurality of the convex portions are provided at intervals in a direction in which the clamping portion extends.

  According to a third aspect of the present invention, in the first or second aspect of the invention, a bending deformation is caused in the picked portion and the sandwiched portion by the sandwiched object inserted between the picked portion and the sandwiched portion. With respect to the bending moment in the direction, the bending rigidity of the clamping part is generally set lower than the bending rigidity of the knob part.

The invention of claim 4 is have a feature for the clips.

That is, the invention according to claim 4 is the invention according to any one of claims 1 to 3 , wherein the clip extends from the fulcrum portion to the proximal end side with a distance from the knob portion. An opening / closing operation part is provided.

According to a fifth aspect of the present invention, in the fourth aspect of the invention, the second hole is formed at a portion corresponding to the opening / closing operation portion.

  According to the first aspect of the present invention, since the projecting portion provided on the clip holding portion protrudes at least to reach the hole of the knob portion, the object to be inserted between the knob portion and the holding portion is inserted. No matter how thin the sandwiched object is, the sandwiched object can be stably sandwiched by the fact that at least three portions of the both sides of the hole and the convex portion of the knob hit the sandwiched object.

  In addition, when a sandwiched object having low rigidity is sandwiched, the convex portion is in a state where a part of the sandwiched article is pushed into the hole. In addition, when a highly rigid object to be clamped is sandwiched, the convex portion is displaced in the direction of being pushed out of the hole by the object to be clamped, so that the clamping part is greatly elastically deformed with the fulcrum as a fulcrum. The object to be clamped can be strongly pressed against the knob by the large elastic force generated with the deformation. Therefore, it is possible to reliably hold the object to be clamped with low rigidity or the object to be clamped with high rigidity.

  In addition, since a convex part is not provided by giving a notch to a clamping part, but is provided by making it protrude from the said clamping part, the intensity | strength of a clamping part falls by providing this convex part. And the convex portion can be formed sufficiently high from the sandwiching portion. Accordingly, the object to be clamped can be pressed against the knob with a sufficiently large force, and the object to be clamped can be prevented from coming out between the pinch part and the knob with a large resistance force by the convex part that protrudes greatly from the clamp part. Can do.

  Moreover, since the clamping part is provided at intervals with respect to the knob part, a large space for sandwiching the object to be clamped between the knob part and the clamping part can be secured. For this reason, even when a relatively thick object to be sandwiched is inserted, the edge of the object to be sandwiched hits the inner surface of the sandwiching part, so that the object to be sandwiched is pushed out from between the sandwiching part and the knob part. It can be prevented from moving. Therefore, even a relatively thick object can be stably held by the knob and the holding part.

Furthermore, since a hole is formed in a part corresponding to the clamping part in the knob part, for example, when a mudler with a clip is integrally injection-molded by injecting molten synthetic resin into a mold. Can use a portion corresponding to the hole in the mold as a moving path of the core for forming the sandwiching portion. Accordingly, it is possible to improve the degree of freedom in the case of injection molding of the clip-added mudler.
Moreover, since the 2nd hole penetrated in the thickness direction is formed in the part on the opposite side to the hole across the part corresponding to the fulcrum part of the clip, the knob part corresponds to the fulcrum part in the knob part. The rigidity of the portion to be reduced can be reduced. For this reason, when the object to be clamped is inserted between the knob portion and the clamp portion, the clip can be rotated flexibly with a portion corresponding to the fulcrum portion of the knob portion 3 as a fulcrum. Therefore, it is possible to more easily and smoothly insert the object to be sandwiched between the knob and the sandwiching part and take out the object to be sandwiched from the gap.

  According to the invention described in claim 2, since the plurality of convex portions are provided at intervals in the extending direction of the sandwiching portion, the object to be sandwiched can be more securely sandwiched by the plurality of convex portions. Can do. Also, for example, when the opening edge of a paper cup as a sandwiched object is sandwiched between the gripping part and the gripping part, the deeper the paper cup is, the more the opening edge becomes the gripping part and the gripping part. It will enter to the back (base end side) between. In this case, each convex portion fulfills a function as a retaining from the paper cup every time it exceeds the opening edge.

  That is, for the shallow paper cup, the convex portion located on the leading end side of the sandwiching portion exceeds the opening edge portion, and for the deep paper cup, the convex portion located on the proximal end side of the sandwiching portion exceeds the opening edge portion. In this state, the paper cup is securely attached to the opening edge of the paper cup. For this reason, since the mudler with a clip can be held in a state of being inserted deeply into a paper cup, the amount of the mudler with a clip protruding upward from the paper cup can be suppressed as much as possible. Therefore, in a state where the mudler with clip is attached to the opening edge of the paper cup, the mudler with clip can be prevented as much as possible from interfering with drinking.

  According to the third aspect of the present invention, with respect to a bending moment in a direction in which bending deformation is caused in the picked portion and the sandwiched portion by the object to be sandwiched inserted between the picked portion and the sandwiched portion, Since the bending rigidity is generally set lower than the bending rigidity of the knob part, when the object to be clamped is inserted between the knob part and the clamping part, the clamping part mainly uses the fulcrum part as a fulcrum. It is possible to prevent a large bending deformation from occurring in the knob portion.

  For this reason, for example, when the opening edge of the paper cup as the object to be clamped is clamped between the knob and the clamp, the bending deformation of the knob can be kept small. Can also be held along the wall of the paper cup. Therefore, even if the mudler with a clip is attached to the opening edge of the paper cup, the mudler with a clip can be prevented from interfering with drinking. In addition, even if a large bending moment that causes plastic deformation is applied, the knob will not be plastically deformed first, so the plastic deformation prevents the knob from becoming difficult to use as a mudler. can do.

According to the invention described in claim 4, since the clip is provided with the opening / closing operation portion extending from the fulcrum portion to the proximal end side with an interval from the knob portion, the opening / closing operation portion is picked. By pressing against the side, the opening / closing operation part is rotated and displaced to the knob part side with the fulcrum part as a fulcrum, and accordingly, the clamping part also rotates in a direction away from the knob part with the fulcrum part as a fulcrum. ing to be dynamic displacement.

  Therefore, by operating the opening / closing operation part, the gap between the knob part and the clamping part can be easily opened and closed, so that even if the object to be clamped has a low rigidity or a thick object, these objects are not covered. The sandwiched object can be easily inserted between the picking part and the sandwiching part without any resistance, and can be taken out from the part.

According to the fifth aspect of the present invention, since the second hole is formed at a portion corresponding to the opening / closing operation part, the opening / closing operation part can be rotationally displaced to the inside of the second hole. It becomes possible. Therefore, since the stroke of the rotational displacement of the opening / closing operation part can be made large, the clamping part can be greatly opened with respect to the knob part. In addition, for example, in the case where a mud with a clip is injection-molded by injecting molten synthetic resin into a mold, an opening / closing operation part is formed in a portion corresponding to the second hole in the mold. Therefore, it is possible to improve the degree of freedom in injection molding of the clip-on mudler.

(First embodiment)
A first embodiment as the best mode for carrying out the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the muddler 11 with a clip shown in the first embodiment includes a scraping portion 2 provided on the distal end side of the shaft portion 1 and a plate provided on the proximal end side of the shaft portion 1. And a clip 4 provided on the knob 3 and is integrally injection-molded with, for example, polystyrene (thermoplastic resin).

  The shaft portion 1 is formed by a flat plate having a predetermined width and thickness extending in a straight line. The mixing portion 2 is formed in an oval shape in a plan view and a bottom view, and is formed in a curved surface so as to be convex on one surface side.

  The knob portion 3 is formed so as to constitute the same plane as the shaft portion 1 by a flat plate having the same thickness as the shaft portion 1 and is formed to extend coaxially with the shaft portion 1. . Moreover, the knob | pick part 3 has a shape which has the constant width part 3a and the taper part 3b, as shown in FIG.1 (b) and (c). The constant width portion 3 a is formed with a constant width wider than the shaft portion 1. The tapered portion 3b is formed so that its width gradually becomes narrower from the width of the constant width portion 3a to the width of the tapered portion 3b.

  The clip 4 is on one surface side of the knob portion 3 and is a fulcrum portion 4a integrally connected to the constant width portion 3a. The clip 4 is spaced from the fulcrum portion 4a to the knob portion 3 on the distal end side. It has the clamping part 4b which extends and clamps a to-be-clamped object with the knob | pick part 3. As shown in FIG. The fulcrum part 4a is formed so as to protrude from the center part in the width direction located on the base end side of the constant width part 3a. The clamping part 4b is formed so as to extend along the center line in the width direction of the constant width part 3a and the taper part 3b.

  Further, the sandwiching portion 4 b is formed to have the same thickness as that of the knob portion 3 and the width thereof is narrower than that of the knob portion 3. In this case, the width of the sandwiching portion 4b is formed to be constant along the left and right side edges of the constant width portion 3a for the portion corresponding to the constant width portion 3a, and the taper for the portion corresponding to the taper portion 3b. It is formed to gradually narrow along the left and right side edges of the portion 3b.

  The knob 3 is formed with a hole 3c penetrating in the thickness direction at a portion corresponding to the sandwiching portion 4b. The hole 3c is formed to have an inner edge that is slightly larger than the outer edge of the holding portion 4b.

  Further, the sandwiching portion 4b is formed with a convex portion 4c protruding so as to slightly enter the air hole 3c from the inner surface (the surface facing the knob portion 3 side). A plurality (three in this example) of the convex portions 4c are provided along the axial direction of the sandwiching portion 4b at a predetermined interval from the tip portion. As shown in FIG. 2, each convex portion 4c is formed so that a part of a cylindrical surface whose axis is a direction orthogonal to the axial direction of the sandwiching portion 4b is an outer peripheral surface. In addition, the convex part 4c is formed in the substantially semicircular column shape in this example.

  Further, as shown in FIG. 2 (a), a bending moment M in a direction that causes bending deformation in the knob part 3 and the clamping part 4b by the object to be clamped W inserted between the knob part 3 and the clamping part 4b. On the other hand, the bending rigidity of the clamping part 4b is set lower than the bending rigidity of the knob part 3 as a whole. Specifically, the cross-sectional secondary moment of the clamping portion 4 b with respect to the bending moment M is set smaller than the cross-sectional secondary moment of the knob 3.

  The bending rigidity is generally represented by the product of a longitudinal elastic modulus that is a specific value depending on the material and a cross-sectional second moment. However, as for the material, since both the knob portion 3 and the sandwiching portion 4b are made of polystyrene and are the same, it is possible to determine the magnitude of the bending rigidity only by the sectional second moment.

  Here, if the cross-sectional secondary moment of the constant width portion 3a in the knob 3 is Is, and the cross-sectional secondary moment of the clamping portion 4b at the position corresponding to the cross-sectional secondary moment Is is It> Is> It. Is set.

In this case, when the cross-sectional secondary moments Is and It are obtained from the dimensions shown for the cross-sections at the positions corresponding to each other in the constant width portion 3a and the sandwiching portion 4b shown in FIG. In addition, the cross-sectional secondary moment It of the clamping part 4b is a position where the convex part 4c does not exist. FIG. 2C shows the state of the constant width portion 3a and the sandwiching portion 4b of the knob 3 before being subjected to bending deformation by the sandwiched object W.
Is = (1/12) × (a + a) × h ³
It = (1/12) × b × h ³
(A + a)> b

  The sectional moment of inertia of the tapered portion 3b and the sandwiching portion 4b at the position corresponding to the tapered portion 3b is also in the relationship of Is> It described above.

  In the muddler 11 with a clip configured as described above, for example, as shown in FIG. 3, an opening edge portion formed in a circular cross section in a paper cup (container) W1 between the knob portion 3 and the clamping portion 4b. (Holding object) By inserting W1a, the opening edge W1a can be held between the knob 3 and the holding part 4b. And the convex part 4c is provided in each position of the front-end | tip part and inward part in the clamping part 4b, and since the any convex part 4c will be in the state exceeding the opening edge part W1a, the opening edge part W1a Can be prevented from easily coming out from between the knob portion 3 and the sandwiching portion 4b.

  That is, the convex portion 4c is not provided by giving a notch to the sandwiching portion 4b, but is provided by projecting from the sandwiching portion 4b. Therefore, by providing this convex portion 4c, the sandwiching portion 4b The strength does not decrease, and the convex portion 4c can be formed sufficiently high from the sandwiching portion 4b. Accordingly, the opening edge W1a can be pressed against the knob with a sufficiently large force, and the opening edge W1a can be prevented from slipping out between the knob 3 and the holding part 4b by the large resistance force of the convex part 4c. Can do.

  In addition, the deeper the paper cup W1, the deeper the opening edge W1a enters (the base end side) between the knob portion 3 and the sandwiching portion 4b. In this case, each convex part 4c exhibits a function as a retaining from the paper cup W1 every time it exceeds the opening edge W1a.

  That is, for the shallow paper cup W1, the convex portion 4c located on the front end side of the sandwiching portion 4b is in a state beyond the opening edge W1a, and for the deep paper cup W1, the convex portion located on the proximal end side of the sandwiching portion 4b. 4c is in a state where it exceeds the opening edge W1a, and is securely attached to the opening edge W1a of the paper cup W1. For this reason, since the mudler 11 with a clip can be held in a state where it is inserted as deeply as possible into the paper cup W1, the amount of the mudler 11 with a clip protruding upward from the paper cup W1 can be suppressed as much as possible. Therefore, even if the mudler with clip 11 is left attached to the opening edge W1a of the paper cup W1, it is possible to prevent the muddler with clip from interfering with drinking as much as possible.

  Further, as shown in FIGS. 4A and 4B, for example, for a slender and slender bag (object to be clamped) W2, between the predetermined two convex portions 4c in the sandwiching portion 4b (the convex portion 4c and the fulcrum) It is possible to prevent slipping out from between the knob portion 3 and the sandwiching portion 4b.

  In addition, a thicker bag (a sandwiched object), a wider bag (a sandwiched object), and the like are securely sandwiched because the two to three protruding portions 4c are pressed against the bag and bitten. be able to. Furthermore, with respect to a thick bag or a wide bag W3 as shown in FIG. 4 (c), by inserting the end in the longitudinal direction between the knob 3 and the clamp 4b, the knob 3 and the clamp It can be clamped by the portion 4b. In this case, since all the convex portions 4c are bitten into the bag W3, the bag W3 can be securely held. Moreover, since the muddler 11 with a clip and the bag W3 such as sugar are arranged in the vertical direction, the muddler 11 with a clip and the bag W3 can be compactly gathered.

  Furthermore, since the convex part 4c provided in the clamping part 4b protrudes so that it may enter slightly into the hole 3c of the knob | pick part 3, the to-be-clamped object inserted between the knob | pick part 3 and the clamping part 4b No matter how thin, the respective portions on both sides of the hole 3c in the knob portion 3 and the three or more portions by the at least one convex portion 4c come into contact with the object to be held stably. be able to.

  Moreover, a part of the object having low rigidity such as a so-called paper napkin is pushed into the hole 3c by the convex part 4c. Therefore, it is possible to securely hold such an object to be clamped with low rigidity. Moreover, about the to-be-clamped thing with high rigidity, the said to-be-clamped object will act so that the convex part 4c may be extruded from the hole 3c. For this reason, the clamping part 4b can be greatly elastically deformed with the fulcrum part 4a as a fulcrum, and the object to be clamped can be strongly pressed against the knob part 3 by a large elastic force generated by this elastic deformation. Therefore, it is possible to securely hold the object having high rigidity.

  Further, the sandwiching portion 4b is formed to extend toward the distal end side with an interval with respect to the knob portion 3, and a wide space for sandwiching an object to be sandwiched between the knob portion 3 and the sandwiching portion 4b. Since it can ensure, even a comparatively thick thing can be reliably clamped by the knob | pick part 3 and the clamping part 4b.

  Furthermore, since a hole 3c is formed in a portion of the knob 3 corresponding to the sandwiching portion 4b, when the muddler 11 with a clip is integrally injection-molded using the polystyrene, the molten polystyrene is injected. In the mold for this purpose, the portion corresponding to the hole 3c can be used as a core insertion path for forming the clamping portion 4b. Therefore, it is possible to improve the degree of freedom when injection-molding the muddler 11 with a clip.

  Moreover, since the bending rigidity of the clamping part 4b is set smaller than the bending rigidity of the knob part 3, when a thing to be clamped is inserted between the knob part 3 and the clamping part 4b, the clamping part 4b is mainly used. It is possible to prevent a large bending deformation from occurring and a large bending deformation from occurring in the knob 3.

  For this reason, when the opening edge W1a of the paper cup W1 is clamped between the knob 3 and the clamp 4b, the bending deformation of the knob 3 can be suppressed as shown in FIG. The scraping portion 2 can also be held along the wall surface of the paper cup W1. Therefore, even if the mudler 11 with a clip is attached to the opening edge W1a of the paper cup W1, the mudler 11 with a clip can be prevented from obstructing drinking. Further, even when a large bending moment M that causes plastic deformation is applied, the knob portion 3 does not cause plastic deformation first, so that the knob portion 3 is difficult to use as a mudler due to the plastic deformation. It can prevent becoming a thing.

{Different forms for carrying out the invention}
(Second Embodiment)
Next, a second embodiment as a different mode for carrying out the present invention will be described with reference to FIG. However, elements common to the constituent elements shown in the first embodiment are denoted by the same reference numerals, and description thereof is simplified.

  The difference between the muddler 12 with a clip shown in the second embodiment and the muddler 11 with a clip shown in the first embodiment is that a second hole 3d is formed in the knob 3. .

  In other words, the second hole 3d is formed in a portion on the opposite side of the hole 3c across the portion of the knob 3 corresponding to the fulcrum part 4a of the clip 4. The second hole 3d is formed so as to penetrate the knob 3 in the thickness direction, and the width of the second hole 3d is the same as the width of the hole 3c. Moreover, the length along the axial direction of the knob 3 in the second hole 3d is formed short so as not to increase the length of the knob 3 in the axial direction.

  In the muddler 12 with a clip configured as described above, the second hole 3d is formed at a portion on the opposite side of the hole 3c across the portion corresponding to the fulcrum 4a of the clip 4 in the knob 3. Therefore, the rigidity of the part corresponding to the fulcrum part 4a in the knob part 3 can be reduced. For this reason, the clamping part 4b corresponds to the fulcrum part 4a in the knob 3 due to the bending moment M (see FIG. 5D) generated by inserting the object to be clamped between the knob 3 and the clamping part 4b. It becomes possible to rotate flexibly in a direction away from the knob 3 with the portion to be supported as a fulcrum. Therefore, the operation of sandwiching the object to be sandwiched between the knob 3 and the sandwiching part 4b and the operation of removing the object to be sandwiched from the gap can be performed more easily and smoothly.

(Third embodiment)
Next, a third embodiment as a different mode for carrying out the present invention will be described with reference to FIGS. However, the same reference numerals are given to the elements common to the constituent elements shown in the second embodiment, and the description will be simplified.

  The difference between the clip-added mudler 13 shown in the third embodiment and the clip-added mudler 12 shown in the second embodiment is that the clip 4 is provided with an opening / closing operation part 4d, and the second The hole 3d is formed at a portion of the knob 3 corresponding to the opening / closing operation unit 4d.

  That is, as shown in FIG. 6, the opening / closing operation part 4d is formed to extend from the fulcrum part 4a of the clip 4 to the base end side (opposite side of the clamping part 4b) with a space from the knob part 3. Has been. In this case, the opening / closing operation portion 4d gradually moves away from the knob portion 3 as it goes from the fulcrum portion 4a toward the proximal end side of the knob portion 3 in a free state where no force is applied to the opening / closing operation portion 4d and the clamping portion 4b. The shape is inclined to be displaced in the direction.

  The second hole 3d is formed so that its inner edge is slightly larger than the outer edge of the opening / closing operation part so that the opening / closing operation part 4d can be inserted when the opening / closing operation part 4d is pressed against the knob 3 side. Has been.

  In the muddler 13 with a clip configured as described above, since the opening / closing operation part 4d is provided on the clip 4, by pressing the opening / closing operation part 4d against the knob 3 side, as shown in FIG. The opening / closing operation part 4d can be pivotally displaced toward the knob part 3 with the part corresponding to the fulcrum part 4a in the knob part 3 as a fulcrum, and the clamping part 4b is moved from the knob part 3 along with this rotational displacement. It can be rotationally displaced in the direction of leaving. That is, by operating the opening / closing operation part 4d, the knob part 3 and the clamping part 4b can be easily opened and closed. Therefore, even if the object to be clamped W has a low rigidity, a thick object, etc., these objects to be clamped W can be easily inserted between the knob part 3 and the pinching part 4b without any resistance, It can be taken out from the space.

  In particular, as shown in FIG. 8, the mudler 13 with the clip sandwiched between the opening edges W1a of the paper cup W1 can be removed from the opening edge W1a without any resistance. For example, the opening edge W1a It is possible to prevent the liquid or the like in the paper cup W1 from splashing due to the resistance at the time of removal from the paper cup.

  In addition, since the second hole 3d is formed at a portion corresponding to the opening / closing operation part 4d, the opening / closing operation part 4d can be rotationally displaced to the inside of the second hole 3d. That is, since the displacement stroke of the opening / closing operation portion 4d can be increased, the opening / closing stroke of the clamping portion 4b relative to the knob 3 can also be increased. Further, when the mud 13 with clip is integrally injection-molded by injecting a molten synthetic resin into a mold (not shown), a portion corresponding to the second hole 3d in the mold is opened and closed. Since it can be used as a core insertion passage for molding 4d, the degree of freedom in injection molding of the clip-added mudler 13 can be improved.

  In each of the above-described embodiments, the example in which the convex portion 4c is provided in the clamping portion 4b so as to slightly enter the hole 3c has been shown. However, the convex portion 4c is configured to reach the hole 3c. It may be configured so as to enter deeper into the hole 3c. That is, the convex part 4c should just be comprised so that the hole 3c may be reached at least.

  Further, the portion of the tip of the convex portion 4c that contacts the object to be clamped is formed of a part of a cylindrical surface (as shown in FIGS. 1 (a) and (d), formed in a semicircular shape when viewed from the front). ), The convex portion 4c is smooth so that the tip portion thereof is a part of a spherical surface (for example, a hemispherical surface) as shown in FIGS. 9 (a) and 9 (b). It may be formed by a convex curved surface.

Further, as shown in FIG. 9C, the convex portion 4 c may be formed by protruding in a triangular shape from the inner surface of the knob portion 3 in a front view. As for this convex part 4c, the vertex part of the triangle has reached at least the hole 3c (in this example, it is slightly inside the hole 3c), and the convex part 4c is directed toward the tip side of the knob part 3 from the vertex part. A front inclined surface that inclines so as to reach the inner surface of the knob portion 3, and a rear inclined surface that inclines so as to reach the inner surface of the knob portion 3 from the apex portion toward the proximal end side of the knob portion 3, These front inclined surface and rear inclined surface form two sides excluding the above-mentioned triangular base. However, the front inclined surface and the rear inclined surface itself are formed in a quadrangular shape as shown in FIG. 9D as a cross-sectional view of the knob 3 (ie, a DD cross-sectional view). That is, the convex portion 4 c corresponds to a shape in which two side surfaces of the triangular prism are formed so as to protrude from the inner surface of the knob portion 3.
When the convex part 4c formed as described above is used, the object to be sandwiched can be smoothly inserted between the knob part 3 and the sandwiching part 4b by the front inclined surface, and the rear inclined surface. The object to be clamped can be pulled out smoothly from between them. Moreover, there is an advantage that an appropriate holding force and frictional force are generated for the object to be sandwiched by acting so that the apex portion bites into the object to be sandwiched. In addition, about the vertex part, you may make it adjust the holding force and frictional force with respect to a to-be-clamped object by rounding in circular arc shape. In addition, when the apex portion is rounded in this way, there is an effect that the insertion and removal of the object to be sandwiched between the knob portion 3 and the sandwiching portion 4b becomes smooth.

Moreover, about the convex part 4c, as shown to FIG.9 (e), you may form by what protrudes in trapezoid form from the inner surface of the knob | pick part 3 by front view. As for this convex part 4c, the upper side surface of the position corresponding to the upper side of the trapezoid (the short side located in the lower part in FIG. 9E) reaches at least the hole 3c (in this example, the inside of the hole 3c). A front inclined surface that inclines so as to reach the inner surface of the knob portion 3 from the upper side surface toward the distal end side of the knob portion 3, and from the upper side surface to the proximal end side of the knob portion 3 And a rear inclined surface that inclines so as to reach the inner surface of the knob portion 3, and the upper side surface, the front inclined surface, and the rear inclined surface form three sides excluding the trapezoidal bottom side described above. It has become. However, the front inclined surface and the rear inclined surface itself are formed in a quadrangular shape as shown in a cross-sectional view of the knob 3 (that is, FIG. 9 (f) which is a FF cross-sectional view of FIG. 9 (e)). Has been. That is, the convex portion 4 c corresponds to a quadrangular prism having a trapezoidal cross section formed by projecting the above-described upper side surface and the three side surfaces including the left and right side surfaces from the inner surface of the knob 3.
When the convex part 4c formed as described above is used, the object to be sandwiched can be smoothly inserted between the knob part 3 and the sandwiching part 4b by the front inclined surface, and the rear inclined surface. The object to be clamped can be pulled out smoothly from between them. In addition, there is an advantage that an appropriate holding force or frictional force is generated on the object to be sandwiched by acting so that the portion of the upper side surface formed with a narrow width bites into the object to be sandwiched. In addition, about the upper side surface, it is possible to adjust the holding force and frictional force with respect to a to-be-clamped object by the narrow width. Further, by putting the corner portion composed of the upper side surface and the front inclined surface and the corner portion made of the upper side surface and the rear inclined surface into a circular arc shape, the object to be sandwiched between the knob portion 3 and the sandwiching portion 4b is inserted. The stocking becomes smoother.

  Moreover, about the shape of each convex part 4c from the cross-sectional direction of the knob | pick part 3 shown to FIG.9 (d) and (f), it has a shape as shown to FIG.9 (g), (h) and (i). It may be a thing. That is, a trapezoidal shape as shown in FIG. 9 (g), an isosceles triangle shape as shown in (h), and a shape obtained by rounding the vertices of an isosceles triangle as shown in (i) Good. In this case, the convex portion 4c formed in the trapezoidal shape as shown in (e) in the front view and in the trapezoidal shape as shown in (g) in the cross-sectional view is finally four from the inner surface of the knob portion 3. It corresponds to the one protruding in the shape of a truncated pyramid. In addition, this convex part 4c may be formed in a truncated cone shape or a polygonal frustum shape such as a triangle, a pentagon, and a hexagon. On the other hand, the convex portion 4c formed in a triangular shape as shown in (c) in a front view and in a triangular shape as shown in (h) and (i) in a cross-sectional view has a pointed apex. This corresponds to a square pyramid with a round shape or a round shape. In addition, this convex part 4c may be formed in polygonal cone shapes, such as a cone, a triangle, a pentagon, and a hexagon. In this case, the apex of the cone or polygonal pyramid may have a sharp shape or a round shape.

Further, as shown in FIGS. 9 (j) and 9 (k), the convex portion 4 c may be configured to have a shape protruding in a quadrangular prism shape from the inner surface of the knob portion 3. As for this convex part 4c, the top surface of the front-end | tip has reached at least the hole 3c (in this example, it has entered slightly in the hole 3c), and the one side surface which mutually opposes is the front end side of the knob | pick part 3. The other side surface faces the base end side of the knob 3. Moreover, planar chamfering (so-called C chamfering) is applied to each corner portion composed of the top surface and each of the four side surfaces.
When the convex part 4c formed as described above is used, the object to be sandwiched can be smoothly inserted between the knob part 3 and the sandwiching part 4b by chamfering located on the tip side, and By the chamfering located on the end side, the object to be clamped can be smoothly pulled out from there. In addition, since the portion of the top surface whose area is reduced by chamfering acts so as to bite into the object to be sandwiched, it is possible to generate an appropriate holding force and frictional force for the object to be sandwiched. In addition, about the area of the top surface, it can adjust by the magnitude | size of the chamfering, and it is possible to adjust the holding force and frictional force with respect to a to-be-clamped object by this.

  Further, as shown in FIGS. 9 (m) and 9 (n), each corner portion composed of the top surface and the four side surfaces is subjected to chamfering (so-called R chamfering) rounded into an arc shape. It may be configured.

  Furthermore, the convex part 4c shown to FIG.9 (j)-(n) may be formed in polygonal column shapes, such as a column shape and a triangle, a pentagon, a hexagon. However, also in that case, it is preferable to perform C chamfering or R chamfering on the corner portion composed of the top surface and the side surface.

  On the other hand, although the example which used the polystyrene as the material which comprises the muddlers 11, 12, and 13 with a clip was shown, it may replace with this material and metal materials, such as another synthetic resin material and stainless steel, etc. may be used.

  Further, as shown in FIG. 10A, the inner surface of the tip portion of the sandwiching portion 4b is inclined so as to gradually move away from the knob 3 as it goes from the convex portion 4c located on the tip side toward the tip of the sandwiching portion 4b. It is preferable to form the surface 4e. By providing such an inclined surface 4e, there is an advantage that it becomes easy to insert the object to be sandwiched between the knob portion 3 and the sandwiching portion 4b.

  Further, as shown in FIG. 10B, the length of the inclined portion 4b is inclined by displacing the tip portion of the holding portion 4b so as to gradually move away from the knob portion 3 toward the tip of the holding portion 4b. A long inclined surface 4e having a large inclination angle may be formed. In this case, it becomes easier to insert the object to be clamped between the knob 3 and the clamp 4b.

  On the other hand, as shown in FIG. 10 (c), the convex portion 4 c is formed so as to protrude toward the knob portion 3 side by curving a part of the clamping portion 4 b toward the knob portion 3 side. May be. In this case as well, as shown in FIG. 10 (d), the tip of the sandwiching portion 4b is bent at an angle to introduce the object to be sandwiched between the picking portion 3 and the sandwiching portion 4b. It is preferable to form the inclined surface 4e.
