  The present invention relates to a chopstick and a chopstick tip for replacement.

  Chopsticks are used on a daily basis in Japanese eating habits, and are often used when eating out at restaurants and restaurants.

  Disposable disposable chopsticks are often used because it is strictly required to be sanitary when eating out.

  However, disposable disposable chopsticks are not friendly to the environment due to waste of resources. On the other hand, it must be guaranteed that it is hygienic.

  In view of the above circumstances, an object of the present invention is to provide an environment-friendly and sanitary chopstick and a replacement chopstick tip.

  The chopsticks of this embodiment include a chopstick tip and a chopstick body to which the chopstick tip is detachably attached. The chopstick tip has an attachment / detachment portion for attaching / detaching to the chopstick body, and the chopstick body attaches / detaches the chopstick tip. A chopstick having a fitting hole into which the part fits.

  In such chopsticks, since the chopstick tip is detachably attached to the chopstick body, replacing only the chopstick tip, which is usually the part that touches food, after use, compared to the case where the entire chopstick is disposable. Since it is environmentally friendly and can always use a new chopstick tip, it is possible to provide hygienic chopsticks.

  At least one of the detachable part and the fitting hole preferably has elasticity. By using the elasticity of at least one of the detachable part and the fitting hole, the chopstick tip and the chopstick body can be attached and detached more easily.

  The detachable part preferably has a plurality of split pieces formed by cutting in the central axis direction from the base end side of the chopstick tip. The detachable part has elasticity by having a plurality of split pieces separated by cutting.

  The detachable part preferably has four split pieces formed by cutting in a cross in the direction of the central axis from the base end side of the chopstick tip. By making the cut into a cross, elasticity is uniformly generated.

  It is preferable that a protrusion is provided on the peripheral surface of the detachable portion. The protrusions can be hooked on the inner wall of the fitting hole and can be attached and detached more reliably.

  It is preferable that the corner | angular part of the base end side of an attaching / detaching part is chamfered. Since the corner portion is chamfered, it is easier to attach the detachable portion to the fitting hole. Moreover, it can prevent that the corner | angular part of the base end side of an attaching / detaching part stands upright.

  The portion having the fitting hole of the chopstick body is preferably formed from a metal cylinder. Even when the chopstick tip and the chopstick body are attached and detached repeatedly, the durability of the chopstick body is improved without causing pain or damage.

  The replacement chopstick tip according to the present invention is a replacement chopstick tip used for the chopsticks described above, and is a replacement chopstick tip having a detachable portion for detachably fitting into a fitting hole of the chopstick body.

  Since such a chopstick tip for replacement is detachably attached to the chopstick body, replacing only the chopstick tip, which is usually the part that comes into contact with food, after use, compared to the case where the entire chopstick is disposable. Since it is environmentally friendly and a new chopstick tip can always be used, a hygienic replacement chopstick tip can be provided.

  It is preferable that the attaching / detaching portion of the replacement chopstick tip has elasticity. By using the elasticity of the detachable part, the chopstick tip and the chopstick body can be attached and detached more easily.

  The attaching / detaching portion of the replacement chopstick tip preferably has a plurality of split pieces formed by cutting in the direction of the central axis from the base end side of the chopstick tip. Since the plurality of split pieces divided by the cuts are provided, the detachable part has elasticity.

  The attachment / detachment portion of the chopstick tip for replacement preferably has four split pieces formed by cutting a cross in the direction of the central axis from the base end side of the chopstick tip. By making the cut into a cross, elasticity will be generated uniformly, and it can be detached in a more stable state

  It is preferable that a protrusion is provided on the peripheral surface of the attaching / detaching portion of the replacement chopstick tip. The protrusions can be hooked on the inner wall of the fitting hole and can be attached and detached more reliably.

It is a disassembled perspective view of the chopsticks in 1st Embodiment. It is a figure which shows the chopstick tip for replacement | exchange in 1st Embodiment, (a) is a side view, (b) is the BB sectional drawing of (a). It is a figure which shows typically the chopstick tip for replacement | exchange in another embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an exploded perspective view of a chopstick 1 according to the present embodiment. As shown in FIG. 1, a chopstick 1 according to this embodiment includes a chopstick body 10 and a chopstick tip 20.

  The chopstick body 10 is joined to the grip portion 11 without a step with a cylindrical grip portion 11 having a slope that becomes thinner as the peripheral surface is directed toward the tip of the chopstick 1, and the peripheral surface has the same slope as the grip portion 11. A cylindrical attachment / detachment receiving portion 12 is included. The detachable receiving portion 12 includes a fitting hole 13 that is a hole provided at the center of the end surface opposite to the joint surface between the grip portion 11 and the detachable receiving portion 12. The attachment / detachment receiving portion 12 is a metal cylinder, and is formed by fitting into the grip portion 11.

  The diameter of the cross section perpendicular to the longitudinal direction of the chopstick body 10 is, for example, 8 mm at the maximum portion, 4 mm at the minimum portion, and 5 mm at the joint surface between the grip portion 11 and the attachment / detachment receiving portion 12. It is possible.

  However, the shape and size of the chopstick body 10 are merely examples, and there is no intention to limit the shape and size. Any shape and size that are easy to use as chopsticks or have a well-balanced design can be used. For example, it is good also as polygonal columns, such as a hexagonal column, and other column shapes instead of a cylinder.

  As the material of the grip portion 11, for example, wood, bamboo, plastic, resin, metal, or the like can be used.

  The material of the detachable receiving portion 12 is preferably a metal. By making the material of the attachment / detachment receiving portion 12 metal, it is possible to improve the durability of the chopstick body 10 without causing pain or damage even if the attachment / detachment of the attachment / detachment portion 22a described later is repeated.

  However, it is not intended to limit the material of the grip part 11 and the attachment / detachment receiving part 12. Any other material that can be used as chopsticks can be used.

  The chopstick body 10 may be integrally formed using plastic. As a result, the cost required for manufacturing can be reduced.

  For example, an adhesive can be used for joining the grip portion 11 and the attachment / detachment receiving portion 12.

  The chopstick tip 20 includes a holding part 21 and an attaching / detaching part 22a.

  The holding part 21 is a cylinder having a peripheral surface that is inclined with the same inclination as the chopstick main body 10 without a step when the chopstick tip 20 is attached to the chopstick main body 10, and its tip (that is, attached to the chopstick main body 10). The end portion on the opposite side of the chopstick body 10 is chamfered so as to be substantially semicircular.

  The attaching / detaching portion 22 a has a cylindrical shape that is joined to the holding portion 21 at the end surface (base end side) opposite to the distal end portion of the holding portion 21 and extends in the longitudinal direction of the holding portion 21. The shape of the detachable portion 22a will be described in detail later.

  The holding part 21 and the attaching / detaching part 22a may be integrally formed. Moreover, the holding part 21 and the attaching / detaching part 22a may be joined by an adhesive or the like.

  The length of the holding portion 21 in the longitudinal direction may be 5 centimeters, for example. The length of the detachable portion 22a in the longitudinal direction may be 15 millimeters, for example.

  The diameter of the cross section perpendicular to the longitudinal direction of the attaching / detaching portion 22a is smaller by a predetermined value (for example, 0.2 millimeters) than the maximum diameter of the cross section perpendicular to the longitudinal direction of the holding portion 21.

  The material of the holding part 21 may be wood, bamboo, plastic, resin, metal, or the like, for example.

  However, the shape, size, and material of the holding portion 21 are examples, and there is no intention to limit the shape, size, and material. Any shape, size, and material that are easy to use as chopsticks or have a good balance in design can be used. For example, the shape may be not a cylinder but a polygonal column such as a hexagonal column, or another column shape.

  As the material of the detachable portion 22a, a material that can generate elasticity in the detachable portion 22a such as wood, bamboo, plastic, or resin can be used.

  Next, the shape of the attaching / detaching portion 22a will be described with reference to FIG. A side view of the chopstick tip 20 is shown in FIG.

  As shown in FIG. 2 (a), the detachable portion 22a is formed from the end surface of the holding portion 21 on the base end side (that is, the chopstick body 10 side when the chopstick body 20 is attached to the chopstick body 10). This is a cylinder extending in the longitudinal direction from the end surface on the opposite side (base end side) to the joint surface between the gripping portion 21 and the attachment / detachment portion 22a toward the joint surface between the attachment / detachment portion 22a and the gripping portion 21 in the central axis direction. And a split piece 23 formed by inserting a cut 26 provided in the form of a plurality of protrusions (projections) 24 having a plurality of protrusions (for example, two) provided so as to go around the peripheral surface. It is configured. In addition, the protruding item | line part 24 is not restricted to the protruding item | line which goes around a surrounding surface, What is necessary is just the protrusion shape from which at least one part protruded.

  Moreover, the corner | angular part on the opposite side (base end side) in the attachment / detachment part 22a is chamfered. The depth of chamfering can be adjusted as appropriate.

  It is preferable that the peripheral surface of the detachable portion 22a is provided with an inclination. In this case, the inclination is such that the diameter of the cross section perpendicular to the longitudinal direction of the attaching / detaching part 22a is compared with the diameter of the end face on the holding part 21 side at the end face opposite to the holding part 21 (base end side). Thus, the length may be the same as the thickness of the cut 26 forming the split piece 23. Further, the inclination is such that the diameter of the section in the direction perpendicular to the longitudinal direction of the attaching / detaching portion 22a is compared with the diameter of the inner wall of the fitting hole 13 on the end surface on the side opposite to the holding portion 21 (base end side). The inclination may be longer by the same length as the thickness of the cut 26 forming the split piece 23. In this case, in a state where the chopstick tip 20 is attached to the attachment / detachment receiving portion 12, the cut 26 forming the split piece 23 is closed by the elasticity of the split piece 23 in the attachment / detachment portion 22a, and the diameter of the attachment / detachment portion 22a is fitted. Since it becomes equal to the inner diameter of the hole 13, it is possible to obtain an effect that it is easy to attach and does not easily fall off.

  A sectional view taken along line BB in FIG. 2A is shown in FIG.

  As shown in FIG. 2B, two cuts 26 forming the split piece 23 are provided so as to cross each other substantially perpendicularly (that is, the cross section in the direction perpendicular to the longitudinal direction becomes a cross) ( It is preferable to put two). Note that the term “substantially vertical” means that it is not necessary to be exactly vertical (that is, some error is allowed). In this case, four split pieces 23 are formed.

  One notch 26 forming the split piece 23 may be provided (one). By making it one, it becomes possible to further reduce the number of production steps.

  Comparing the case where one notch 26 forming the split piece 23 is provided (put one) and the case where two cuts 26 forming the split piece 23 are provided (two put), When the two cuts 26 are provided, the elasticity of the detachable portion 22a can be more evenly generated, and the detachability and stability are further improved. Note that two or more cuts 26 forming the split pieces 23 may be provided.

  It is preferable that the corner of the detachable portion 22a on the side opposite to the gripping portion 21 (base end side) is chamfered. By doing so, it becomes easier to attach the chopstick tip 20 to the chopstick body 10. Furthermore, it is possible to prevent the corner portion from standing up and down by colliding with the attachment / detachment receiving portion 12.

  The shape of the detachable portion 22a is not limited to a circular column, and may be a columnar shape such as a quadrangular column. In that case, the shape of the fitting hole 13 is a columnar shape such as a quadrangular prism so as to match the detachable portion 22a. When the shape of the attaching / detaching portion 22a and the fitting hole 13 is a pillar shape other than a cylinder such as a quadrangular prism, the attaching / detaching portion 22a can be prevented from rotating when the chopsticks 1 are used.

  In addition, the split piece 23 and the protruding item | line part 24 can be selectively provided. That is, the attaching / detaching portion 22 a in the present embodiment may include only the split piece 23 or may include only the protruding strip portion 24.

  The shape of the fitting hole 13 is a shape corresponding to the shape of the detachable portion 22a. For example, when the shape of the detachable portion 22a is a cylinder, the shape of the fitting hole 13 is the diameter of the circle. The cylinder 22 is a circle smaller by a predetermined value (for example, 0.1 mm) than the diameter of the circle of the cylinder in the portion 22a.

  By doing so, in this embodiment, since the detachable part 22a is elastic by providing the split piece 23, the detachable part 22a can be inserted into the fitting hole 13, but with a certain force. If you don't add it, it will be missing. As a result, the chopstick tip 20 does not fall off the chopstick body 10 while the chopstick 1 is in use.

  Furthermore, in this embodiment, since the elasticity of the attaching / detaching portion 22a is used, an effect that the structure is not complicated is obtained.

  Next, the usage example of the chopsticks 1 in this embodiment is demonstrated.

  A restaurant or the like includes a chopstick body 10 and a chopstick tip 20 packaged in a bag or stored in a case. A customer at a restaurant places an unused chopstick tip 20 on a chopstick body 10 provided in the store and uses it. After use, the chopstick body 10 is repeatedly used after washing. The chopstick tip 20 is replaced with a new chopstick tip 20 each time it is used once.

  With such a method of use, the chopstick tip 20 that is in contact with food is always clean because it can be used unused. Further, since only the chopstick tip 20 is exchanged after use, resources can be used more efficiently than disposable chopsticks that discard the entire chopstick every time it is used.

  Another usage example of the chopsticks 1 in this embodiment will be described.

  A user of the chopsticks 1 carries at least the chopstick body 10. An unused chopstick tip 20 is provided at a restaurant such as a cafeteria, and the user uses the chopstick 1 by attaching the unused chopstick tip 20 provided in the store to the chopstick body 10. After use, only the chopstick tip 20 is replaced with a new chopstick tip 20. The chopstick body 10 is cleaned by the user as appropriate for the user.

  As a result, the chopstick tip 20 that is in contact with the food is always clean because it can be used unused. In addition, since only the chopstick tip 20 is replaced after use, resources can be used more efficiently compared to disposable chopsticks that discard the entire chopstick every time it is used. Furthermore, since the only part to be carried is the chopstick body 10 which is a part of the whole chopsticks, it can be carried easily.

  When the chopsticks provided at a restaurant or the like are reusable chopsticks made of metal or plastic, there may be a resistance to using chopsticks used by others even after washing. In addition, if disposable disposable chopsticks are used, resources may be wasted.

  By using the chopsticks 1 of the present embodiment as in the above-described usage example, it is possible to minimize the consumption of resources without feeling resistance to using chopsticks used by others. Become.

  Note that the above usage example is merely an example, and it is needless to say that the chopsticks 1 can be used in various other conceivable ways.

  Next, a modification of the present embodiment will be described with reference to FIG.

  The attachment / detachment portion 22b in the present modification extends in the longitudinal direction of the chopstick tip 20 from the end surface on the proximal end side of the holding portion 21 (that is, the end surface on the chopstick body 10 side when the chopstick tip 20 is mounted on the chopstick body 10). For example, it has a columnar shape such as a cylinder, and is provided with a bulging portion 25 at the center in the longitudinal direction that has a relatively large width in the direction perpendicular to the longitudinal direction as compared with the surrounding width.

  In addition, when the width of the perpendicular direction with respect to the longitudinal direction is large, for example, when the shape of the detachable portion 22b is a cylinder, it means that the diameter in the section perpendicular to the longitudinal direction is long. For example, when the shape of the detachable portion 22b is a polygonal column, it indicates that the diagonal line in the cross section perpendicular to the longitudinal direction is long.

  In this modification, the chopstick body 10 and the chopstick tip 20 can be attached and detached using the elasticity of the attaching / detaching portion 22b and the bulging portion 25.

  In addition, the bulging part 25 may exist in places other than the center of the longitudinal direction of the attachment / detachment part 22b.

  Next, still another modification of the present embodiment will be described. In the embodiment, the detachable part 22a has elasticity, but the detachable receiving part 12 may have elasticity. In that case, the attaching / detaching portion 22a may not have elasticity. Therefore, the material of the detachable portion 22a is not limited to a material that can cause elasticity in the detachable portion 22a such as wood, bamboo, plastic, or resin, and may be a material such as other metals.
