  For example, when the chopstick box body is covered with a lid as in Patent Document 1, it is difficult to adjust the engagement between the chopstick box body and the lid. If the engagement is strong, the lid is difficult to open. There was a case. Further, since the entire chopstick box body opening is exposed, the lid may be dropped when the lid is opened.

  Next, for example, a chopstick box that slides and slides a lid sideways as in Patent Document 2 has a long movement distance when the lid is pulled out, and requires time and space for sliding movement to take out the chopsticks. In addition, it is difficult to take out the chopsticks unless the lid is completely removed from the chopstick box body. Furthermore, when the lid is stored in the chopstick box main body, it is necessary to insert a convex protrusion into the concave groove arranged in the longitudinal direction of the opening end of the chopstick box main body, and it is necessary to fit the convex protrusions in the longitudinal direction of the lid. Because of the long distance combination in the direction, precise combination operation and component dimensional accuracy were required.

  In the case of a plastic chopstick box, it is easy to break due to dropping or impact when carrying it, and the lid cannot be opened or closed. For example, in the hinge type as in Patent Document 3, the lid and the chopstick box are loosely fitted. was there. If the lid and the chopstick box are loosely fitted, the lid may be opened due to vibration while being carried, and the stored chopsticks may fall. Further, since the rotation angle of the lid is limited by the hinge structure, when the operation is performed up to a rotation angle exceeding the limit, the hinge portion may be damaged and the lid opening / closing function may be impaired.

  Also, unless the combination of chopsticks and chopstick box is used, the chopsticks and their noise cannot be suppressed. When using chopsticks of different sizes and shapes, there will be a dimensional difference and the chopsticks will be unstable. Further, by reducing the gap between the chopsticks in the chopstick box, the first insertion of the chopsticks becomes inconvenient, and additional parts are added, which increases costs and labor for cleaning. Moreover, if another part is lost, the effect is lost.

  The problem to be solved is that the chopsticks can be taken out without completely removing the lid, and the impact can be absorbed even when dropped, and the rattle between the chopstick box and the stored chopsticks can be prevented. It is a point to do.

  The invention of claim 1 comprises a chopstick box main body having an upper surface opening formed with a chopstick storage portion inside, and a lid made of an elastic member closing the upper surface opening of the chopstick box main body, and one end of a side wall of the chopstick box main body The chopsticks take-out port is formed by providing a notch in the lid, and a closure portion capable of closing the take-out port of the chopstick box body is provided in the lid, and the closure portion of the lid is elastically bent and deformed to A chopstick box characterized by opening and closing a take-out port.

It has been.

  Further, in order to attach the chopstick box body 4 and the lid 5, three types of first to third protrusions 22, 23, 24, which are obliquely upward on the upper edge side of the chopstick box body 4, are continuous. It is provided in a circumferential shape. In other words, except for the middle portion of the upper edge portion of the left and right side surface portions 7 and 8, one end side, and the other end side, a ridge 22 having a protruding length D that is a protruding amount from the left and right side surface portions 7 and 8 is provided. A protrusion 23 having a protruding length E (D <E) having a protruding amount larger than the protruding length D is provided at an intermediate portion of the upper edge portion. Further, on one end side and the other end side of the upper edge portion, a protrusion 24 having a protruding length F (D> F) having a protruding amount smaller than the protruding length D is provided. On the other end side, a protrusion 22 having an overhang length D is provided.

  On the other hand, two types of first and second grooves 25, 26 having inward groove widths engaging with the protrusions 22, 23, 24 are continuously provided on the lower surface of the lid body 13 in a circumferential shape. That is, the groove 25 except for the middle part of the right and left edges of the lid body 13 is arranged to face the ridges 22 and 24, and is the groove width D ′ of the groove 25 slightly larger than the overhanging length D? Alternatively, they are formed in substantially the same size (D ′ <D, D ′ = D). Further, the groove width D ′ of the groove 25 is formed larger than the overhang length F (D ′> F). Furthermore, the groove width E ′ of the intermediate groove 26 facing the protrusion 23 is formed to be approximately the same as the overhang length E (E ′ = E). A groove 25 having a groove width D 'is provided on the other end side. As a result, the engagement force between the ridges 22, 23, 24 and the grooves 25, 26, 27 between the chopstick box body 4 and the lid 5 is reduced in the following order due to the size of the engagement area. Become. That is, the engagement force between the protrusion 23 and the groove 26, the engagement force between the protrusion 22 and the groove 25, and the engagement force between the protrusion 24 and the groove 27 are in this order.

  Further, on the inner side of the left and right occluded portion 14B of the lid 5, a stopper piece 28 capable of abutting the end faces 7A, 8A of the left and right side surfaces 7, 8 projects downward from the lid body 13. The lower end of the stopper piece 28 is formed so as to reach the inner bottom surface 6A or the vicinity of the inner bottom surface 6A.

  Next, the effect | action is demonstrated about the said structure. When storing the cleaned chopsticks 1 in the cleaned chopstick box 2, the chopsticks 1 are stored in the chopstick storage section 3 of the chopstick box body 4 with the upper opening 12 opened. At this time, the grip 1A of the chopstick 1 is taken out and the chopstick tip 1B is arranged on the other end face 10 side. Next, the lid 5 is closed. In this closed lid, the lid 5 is disposed so as to cover the upper opening 12, and the outer fitting portion 15 is fitted to the other end surface portion 10, and grooves 25, 26, 27 are formed in the ridges 22, 23, 24. And the fitting portion 19 is fitted to the fitting receiving portion 20 and the closing portion 14 is opposed to the take-out port 9 to be closed. At this time, the fitting portion 19 is fitted to the fitting receiving portion 20 while slightly pulling the knob 16 using elasticity with the outer fitting portion 15 as the fixed side. Thereby, one end side of the lid 5 fitted to the fitting receiving portion 20, that is, the fitting portion 19, and the other end side of the lid 5 fitted outside to the other end, that is, the outer fitting portion 15 are in a tension state. As the lid is closed. Then, the protrusion 11 can press the chopstick 1 while being pressed against the upper surface of the chopstick 1. In the engagement between the protrusions 22, 23, 24 and the grooves 25, 26, 27, the protrusion 23 having a large protrusion amount E is engaged with the groove 26 having a large groove width E '. The resultant force is stronger than the other part. On the other hand, the protrusion 22 having a small protrusion amount D is engaged with the groove 25 having a small groove width D ′, so that the engaging force is weaker than the other part. Yes.

  In this state, the chopstick 1 is stored in the chopstick box 2 and carried. When the chopsticks 1 are stored, the grip portion 1A of the chopsticks 1 is disposed at a location where the depth A is large, the chopstick tip 1B is disposed at a location where the depth B is shallow, and the protrusion 11 is pressed against the upper surface of the chopsticks 1. As a result, movement of the chopsticks 1 in the chopstick box 2, that is, rattling can be suppressed.

  In addition, even if the chopstick box 2 is dropped, a closed portion 14 and an external fitting portion 15 made of an elastic member integrated with the lid body 13 appear on both sides of the chopstick box 2, so these portions are on the floor. The impact can be absorbed even if it hits.

  When the chopsticks 1 are taken out, first, the knob 16 is pushed upward from below to remove the fitting portion 19 from the fitting receiving portion 20. Next, using the elasticity of the lid 5, the knob 16 is lifted obliquely upward to open the outlet 9. The chopsticks 1 can be taken out from the take-out port 9.

  At this time, when it is difficult to take out the chopsticks 1 from the take-out port 9, the engaging force between the ridges 22, 23, 24 of the chopstick box body 4 and the grooves 25, 26, 27 of the lid 5 is as described above. Since the side is weak and the middle part is strong, when the knob 16 is lifted obliquely upward, the engagement on the take-out port 9 side is released. Further, when the knob 16 is lifted obliquely upward, the engagement between the take-out port 9 side and the intermediate portion side is released, and the lid 5 is opened widely so that the take-out port 9 side of the upper opening 12 is opened. Further, even when the knob 16 is lifted obliquely upward with the same force, the engaging force of the intermediate portion is increased, so that the engaging force is won and the upper opening 12 is not further opened. When the chopstick box body 4 and the lid 5 are separated to clean the chopstick box 2, the lid 5 can be separated from the chopstick box body 4 by lifting the knob 16 with a larger force and sliding it to the other end side. .

  As described above, the embodiment includes the chopstick box main body 4 having the storage portion 3 for the chopsticks 1 formed therein and having an upper surface opening, and the lid 5 made of an elastic member for closing the upper surface opening of the chopstick box main body 4. The chopstick box body 4 is provided with a notch at one end of the side wall to form a take-out port 9 for the chopsticks 1, and a closing portion 14 for closing the take-out port 9 of the chopstick box body 4 is provided on the lid 5. The chopsticks can be easily taken out without completely removing the lid 5 by elastically bending and deforming the closing portion 14 of the lid 5 to open and close the take-out port 9 of the chopstick box body 4. Further, since the lid 5 is provided with a closing portion 14 for opening and closing the take-out port 9 of the chopstick box body 4 using an elastic member, the lid 5 is bent from one end side to open only the take-out port 9 of the chopstick box body 4. An opening for taking out the chopsticks 1 can be secured, and the chopsticks 1 stored in an easy operation can be taken out without completely removing the lid 5. Therefore, it is possible to prevent the chopsticks 1 from dropping out and becoming dirty or lost.

  In addition, the lid 5 is securely closed without the opening 9 being easily opened and closed or the lid 5 being removed due to vibration during carrying.

  Moreover, by making the protrusion amount F of the protrusion 24 of the chopstick box body 4 on the side of the chopstick 1 outlet 9 side smaller than the other protrusion amounts D and E, the engagement with the lid 5 becomes weaker and elastically bent and deformed. The closing part 14 of the lid 5 to be made can be deformed more easily.

  In addition, by covering both edges of the chopstick box body 4 with both ends of the lid 5, the shock is absorbed against a drop impact from any angle, or the chopstick box body 4 does not easily collide directly with the ground, etc. Damage to the chopstick box body 4 and the chopstick 1 can be suppressed. Since the lid 5 itself is an elastic deformation member, the opening / closing operation thereof is not affected. Furthermore, the table on which the chopstick box 2 is placed is not damaged.

  Further, by deepening the take-out port 9 side and tilting the inner bottom surface 6A of the chopstick storage unit 3 of the chopstick box body 4 as the grip portion 1A side of the chopstick 1 so as to become shallower in the direction of the chopsticks 1B of the chopsticks 1, The top surface is parallel. By forming the protrusion 11 placed on the back of the lid into contact with the chopstick 1 and pressing it, the chopstick 1 is fixed and does not move in the chopstick box body 4. Therefore, scratches caused by friction between the chopsticks 1 and the chopstick box body 4 can be prevented, rattling noise of the chopsticks 1 can be suppressed, and dirt on the chopsticks 1 after the meal does not spread widely on the other surface in the chopstick box 2.

  Further, when the chopsticks 1 are put in and out, only the thick side of the chopsticks 1 (the grip portion 1A side) is exposed from the take-out port 9, so that only the thick side of the chopsticks 1 can be held and put in and out, which is hygienic. Even if the size and shape of the chopsticks 1 are changed, the chopsticks 1 can be held down by the elastic deformation. At the same time, the inner bottom surface 6A of the chopstick storage unit 3 of the chopstick box body 4 is inclined so as to become shallower in the direction of the chopsticks 1 (in the direction of the chopstick tip 1B), so It becomes the bottom surface 6A side, and even if the dirt of the chopsticks 1 is attached to the chopstick box main body 4, the dirt can be easily removed.

  With such a structure, it is possible to obtain a simple lid opening / closing operation and a chopstick 1 insertion / removal operation, safety against shock and stability as an operation function can be obtained, and at the same time, the backlash of the chopsticks can be suppressed.

  As described above, the chopstick box according to the present invention can be applied to various chopsticks.
