Description

  The present invention relates to chopsticks, and more particularly, to a storage-type chopsticks excellent in portability.

  As a conventional technology for storage-type chopsticks with excellent portability called My chopsticks, it consists of a pair of chopstick bodies and a cap member, and the chopstick bodies are inserted and removed individually in two holes formed in the cap member. A structure that can be accommodated is known (for example, Patent Document 1).

JP 2008-55084 A

  However, the above-described prior art chopsticks must be paired separately from each other when used, and each pair of chopsticks must be individually pulled out from the cap member hole. Each one must be individually inserted into the hole of the cap member, which requires troublesome operations for taking out and storing.

  In addition, since the paired chopstick bodies are individually stored in the two holes formed in the cap member, a gap is formed between the two chopstick bodies in the stored state, and miniaturization is prevented accordingly. In addition, since the two chopstick bodies protrude from the cap member at a distance from each other in the retracted state, the chopstick body protruding from the cap member is bulky, and the two chopstick bodies are carried when being carried. There was a thing that portability was bad, for example, an object might get caught in the gap between main bodies.

  The problem to be solved by the present invention is to make the storage-type chopsticks excellent in handleability and portability, and to further reduce the size.

  The chopsticks according to the present invention have a chopstick tip part (12) for gripping food and a chopstick base part (14) gripped by hand, and detachably engage with each other to engage the chopstick bodies (10). A pair of chopstick main bodies (10) provided with engaging portions (16, 18) for releasably connecting them, and the chopstick tip portions (12) of the pair of chopstick main bodies (10) in a combined state so as to be removable. And a cap member (30) having one chopstick storage part (34) for storage.

  According to this configuration, the pair of chopstick main bodies (10) is a single chopstick storage portion of the cap member (30) collectively as a single rod-like body in a coupled state in which the engaging portions (16, 18) are engaged with each other. Since the chopstick body is removed and inserted into (34), the operation of taking out and storing the chopstick body is less troublesome than the conventional one in which the chopstick body is inserted into and removed from the chopstick storage section. Further, since the pair of chopstick bodies (10) are collectively stored in one chopstick storage section (34) in a combined state, the cap member (30) can be made smaller than the conventional one.

  In the chopsticks according to the present invention, preferably, in the pair of chopstick bodies (10), at least the chopstick base portion (14) has a flat surface to be joined to each other in a combined state, and the flat portions (12B, 14B). The engaging portions (16, 18) are formed in the upper part.

  According to this configuration, since the flat portions (12B, 14B) of the paired chopstick bodies (10) are joined together, there is no gap between the two chopstick bodies (10), so the whole is compact. The portion of the chopstick body (10) protruding from the cap member (30) is not bulky, and there is no possibility that an object will be caught between the two chopstick bodies (10) when being carried.

  In the chopsticks according to the present invention, preferably, the cap member (30) is in the longitudinal direction of the cap member (30) from the entrance (36) through which the chopstick body (10) is inserted into and removed from the chopstick storage part (34). A drain opening (38) communicating with the chopstick storage part (34) is formed at the opposite end as viewed.

  According to this structure, water can be poured into the chopstick storage part (34) from the entrance / exit (36), and the water can be drained to the outside through the drain opening (38). Thereby, the chopstick storage part (34) can be washed with water satisfactorily.

  In the chopsticks according to the present invention, it is preferable that the pair of chopstick main bodies (10) are continuously connected to a portion where the pair of chopstick main bodies (10) are accommodated in the cap member (30) so as to surround the outer periphery of the pair of chopstick main bodies (10). An annular ridge portion (20) or a concave groove portion (38) is formed, and the ridge portion (20) of the chopstick body (10) is formed in the chopstick storage portion (34) of the cap member (30). Alternatively, a concave groove portion (38) or a ridge portion (20) into which the concave groove portion (38) is detachably fitted is formed.

  According to this configuration, the chopstick storage part (34) of the pair of chopstick bodies 10 by the engagement of the annular protrusion (20) and the concave groove (38) when the pair of chopstick bodies (10) is coupled. More secure prevention is performed.

  According to the chopsticks according to the present invention, the pair of chopstick bodies are inserted into and removed from the chopstick storage part of the cap member as a single rod-like body in a coupled state where the engaging parts are engaged with each other. The operation of taking out and storing is less troublesome than the conventional one that is inserted and removed from the chopstick storage part one by one, and the handling is improved. Further, since the pair of chopstick bodies are collectively stored in one chopstick storage portion in a combined state, the cap member can be made smaller than the conventional one.

  The tip portion of the chopstick tip 12 has a hemispherical shape, and the cross-sectional shape from the tip portion toward the side of the chopstick base portion 14 changes from a circular shape to a semicircular shape, and further from a semicircular shape to a semielliptical shape (FIG. 13). reference). The chopstick tip portion 12 is composed of a semicircular / semi-elliptical surface portion 12A and a flat surface portion 12B formed by a half surface of a circle and an ellipse in a semicircular and semi-elliptical portion.

  The chopstick base portion 14 has a semi-elliptical cross-sectional shape over its entire length, and is composed of a semi-elliptical surface portion 14A and a flat surface portion 14B formed by a half-divided surface of the ellipse. The flat surface portion 14B is formed with concavo-convex engaging portions 16 and 18 that are engaged with each other by a pair of chopstick bodies 10 so as to be detachable and coupled to each other so as to be separable. That is, the pair of chopstick bodies 10 are joined to each other in a state where they are joined to each other, and the flat surfaces 12B and 14B are formed on the surfaces, and the concave and convex engaging portions 16 and 18 are formed on the flat surface portion 14B. The concave and convex engaging portions 16 and 18 are concave portions or convex portions that are detachably fitted to each other, and may be, for example, a combination of a hemispherical concave portion and a hemispherical convex portion that complement each other.

  It should be noted that the outer diameter of the semi-elliptical surface portion 14A is a semi-circular / semi-elliptical surface portion at the boundary portion between the semi-circular / semi-elliptical surface portion 12A of the chopstick tip portion 12 and the semi-elliptical surface portion 14A of the chopstick base portion 14. By being larger than the outer diameter of 12A, the stepped surface portion 22 exists. On the other hand, the flat surface portion 12B of the chopstick tip portion 12 and the flat surface portion 14B of the chopstick base portion 14 are one continuous flat surface having no step.

  As shown in FIGS. 6 and 9, the chopstick tip portion 12 is near the end portion on the side continuous with the chopstick base portion 14 (the portion stored in the chopstick storage portion 34 of the cap member 30 described later). A protruding portion 20 having a semicircular cross section that forms a continuous annular shape (elliptical annular shape) surrounding the outer periphery of the chopstick tip portion 12 in a coupled state of the pair of chopstick main bodies 10 is formed. The protruding portion 20 exists over the entire circumference of the pair of chopstick bodies 10 in a coupled state.

  The cap 30 is made of plastic or metal, and as shown in FIGS. 1 to 6 and 12, the cap 30 has a clip portion 32 having a spring property for attachment to clothes (pocket) on the outside, and It has a cap structure with a clip equivalent to a cap. The cap 30 has a hollow structure and has one chopstick storage part 34 (see FIG. 6). The chopstick storage part 34 stores the entire chopstick tip part 12 of the pair of chopstick main bodies 10 in a detachable manner through an entrance 36 opened at one end of the cap 30.

  The cross-sectional shape of the chopstick storage part 34 is, on the entrance / exit 36 side, a cross-sectional shape on the chopstick base portion 14 side of the chopstick tip portion 12 in a coupled state of the pair of chopstick main bodies 10, that is, an ellipse (see FIG. 5), and has an elliptical shape that shrinks toward the other end of the cap 30. On the inner peripheral surface of the chopstick storage part 34 in the vicinity of the entrance / exit 36, as shown in FIG. 6, a concave groove part (step part) 38 into which the protrusion 20 is detachably fitted in a clip stop manner is formed. Has been. The recessed groove portion 38 exists over the entire inner peripheral surface of the chopstick storage portion 34.

  As shown in FIGS. 4 and 6, a drain opening 40 that communicates with the chopstick storage part 34 is provided at the end opposite to the entrance / exit 36 of the cap member 30 in the longitudinal direction of the cap member 30.

  According to the present embodiment, the pair of chopstick main bodies 10 are joined to each other by the engagement of the concave and convex engaging portions 16 and 18 so that the flat portions 12B and 14B are closely joined to each other and form one bar shape. In the combined state (see FIG. 7), the chopstick base 12 is collectively stored in the only chopstick storage part 34 of the cap member 30. In this stored state, in the pair of chopstick main bodies 10, the chopstick base portion 14 protruding outward from the cap member 30 forms one oval bar shape.

  In this way, since the pair of chopstick main bodies 10 are collectively stored in one chopstick storage part 34 in a coupled state, the cap member 30 can be made smaller than the conventional one. In this stored state, the flat portions 14B of the pair of chopstick main bodies 10 are tightly joined, so that the portion of the chopstick main body 10 that protrudes outside the cap member 30, that is, the chopstick bases of the pair of chopstick main bodies 10 There is no gap between the portions 14. As a result, the overall size of the chopsticks in the stored state can be reduced, and in particular, the portion protruding from the cap member 30 does not become bulky.

  In addition, since there is no gap between the chopstick base portions 14 of the pair of chopstick main bodies 10, there is no possibility that an object will be caught between the two chopstick main bodies 10 when being carried, and the chopstick base portions 14 have a single elliptical bar shape. Coupled with this, it can be handled as if it were a writing instrument with a cap like a fountain pen.

  In this stored state, as shown in FIG. 6, the pair of chopstick main bodies 10 is coupled with the stepped portions 22 of the pair of chopstick main bodies 10 in contact with the end face portion 42 of the cap member 30 on the entrance / exit 36 side. The protrusions 20 that exist over the entire circumference of the state are fitted to the concave groove 38 in a click-stop manner, so that there is no rattling in the insertion / removal direction, and there is no rattling from the cap member 30 of the chopstick body 10. Pulling out is surely prevented and the storage state is ensured.

  Further, since the chopstick base portions 14 of the pair of chopstick main bodies 10 protruding outside the cap member 30 are coupled by the concave and convex engaging portions 16 and 18, the pair of chopsticks protruding outside the cap member 30 when being carried. The chopstick base part 14 of the main body 10 does not move relative to each other. This improves portability.

  In use, the cap member 30 and the chopstick base portion 14 of the coupled chopstick body 10 are grasped with the left and right hands, and the fitting between the concave groove portion 38 and the protruding portion 20 is released while the coupled state is maintained. The tip 12 is extracted from the chopstick storage part 34. Then, in the manner of splitting the chopsticks, the pair of chopstick main bodies 10 are gripped with the left and right hands and moved away from each other, and the engagement of the concave and convex engaging portions 16 and 18 is released. As a result, the pair of chopstick bodies 10 are separated from each other to form a pair of chopsticks. Since the chopstick body 10 has the flat portions 12B and 14B, it does not roll carelessly on the table.

  At the time of use, as shown in FIG. 14, the cap member 30 can be used as a chopstick rest in a state of being prevented from rolling by the clip 32. As shown in FIG. 15, a part of the outer surface of the cap member 30 may be a flat portion 46 for chopstick rests.

  When the chopstick body 10 is stored in the cap member 30, the flat portions 12B and 14B of the pair of chopstick bodies 10 are joined to each other to engage the concavo-convex engaging portions 16 and 18, so that the pair of chopstick bodies 10 are connected to each other. Combine to form a single bar. In this coupled state, the chopstick base 12 is inserted into the chopstick storage part 34 through the entrance 36 of the cap member 30.

  By this insertion, the protruding portion 20 gets over the portion 44 while elastically deforming the portion 44 (see FIG. 6) between the end surface portion 42 of the cap member 30 and the recessed groove portion 38 in the expansion direction, The stepped portions 22 of the pair of chopstick main bodies 10 are in contact with the end surface portion 42 of the cap member 30 on the entrance / exit 36 side, and the ridge portion 20 is fitted into the concave groove portion 38 in a clip stop manner. As a result, the pair of chopstick main bodies 10 are collectively stored in the single chopstick storage part 34 of the cap member 30 in a combined state.

  In this way, the pair of chopstick bodies 10 is inserted into and removed from the chopstick storage part 34 of the cap member 30 as a single rod-like body in the combined state. The operation is less troublesome than the conventional one that is inserted and removed, and the handling is improved.

  Since the cap member 30 has a drain opening 40 at the end opposite to the inlet / outlet 36, the water flowing into the chopstick storage part 34 from the inlet / outlet 36 is water when the cap member 30 is washed with water. Water is drained to the outside through the opening 40 for extraction. Thereby, the chopstick storage part 34 can be washed with water satisfactorily. In addition, the chopstick storage part 34 can be easily cleaned, and the chopstick storage part 34 can be dried quickly and satisfactorily.
