Description

  The present invention relates to a chopstick having a handle portion that is easy to hold, and in particular, an easy-to-hold chopstick in which a non-slip flexible synthetic resin tube is elastically fixed within a certain range in the length direction of the chopstick. About.

Currently, many types of chopsticks for meals have been proposed.
Various materials such as wood, bamboo, plastic, and metal are also used.
For painting and patterning, many means such as applying a synthetic paint or lacquer or using a film have been proposed.

Among these proposals are those for improving the functionality of chopsticks in addition to those for obtaining design effects by painting and patterning.
For example, in addition to means for preventing deterioration and corrosion by devising surface processing such as painting, measures for improving functionality have been taken such as making the cross-sectional shape of chopsticks easier to hold.

By the way, as one of these functional additions, there is a functional requirement such that it is easy to hold when holding chopsticks, and that it is difficult to grip and drop food firmly when gripping food.
And about these functional improvement, what was excellent also in terms of manufacturing efficiency was calculated | required from the standpoint of the person who performs manufacture and sale.

Against this background, for example, Patent Document 1 proposes to cover the vicinity of the tip of the chopsticks with silicon rubber or the like having a large friction coefficient and excellent heat resistance in order to make it easy to sandwich food.
In Patent Document 2, a tube-like soft elastic material for preventing slipping attached to a grip portion of a pencil or chopstick is proposed.

However, Patent Document 1 focuses on facilitating grasping of food and is not a proposal for the side using chopsticks.
In addition, Patent Document 2 is a proposal of a member for attaching to a pencil or chopstick as a retrofit, and it is difficult to say that consideration is given to the usage environment such as a shape unique to chopsticks and washing. .

JP 2008-80075 A JP 2007-151446 A

As shown above, many proposals have been made for conventional chopsticks for meals in order to enhance functionality according to the purpose of use of the chopsticks.
However, although these proposals have a certain effect from the viewpoint of not slipping, problems still remain in terms of usability of chopsticks such as thickness and ease of holding, and what is a satisfactory proposal I can not say.

The present invention has been made against the background described above.
That is, the object of the present invention is to easily impart a non-slip function, and to provide a unique color effect in addition to non-slip with a skillful combination of a heat-shrinkable cylindrical film and a flexible synthetic resin tube. It is to provide an easy chopstick and a manufacturing method thereof.

  As a result of earnest and research to solve the above-mentioned problems, by forming a peripheral groove on the chopsticks and fixing a flexible synthetic resin tube here, we obtained the knowledge that it becomes difficult to slip when grasped. Based on this, the present invention has been provided.

  That is, the present invention resides in (1) an easy-to-hold chopstick in which a non-slip flexible synthetic resin tube is elastically fixed to the bottom surface of a peripheral groove formed in a certain range in the length direction of the chopstick. .

  That is, according to the present invention, (2) a colored heat-shrinkable cylindrical film is heat-shrink-fixed on the bottom surface of a peripheral groove formed in a certain range in the length direction of the chopsticks. It is easy to hold chopsticks, which are colored and translucent and have a non-slip flexible synthetic resin tube that is elastically fixed.

  That is, the present invention resides in (3) the chopstick that is easy to hold as described in (1) or (2) above, wherein the chopstick surface and the flexible synthetic resin tube surface are flush with each other at the boundary portion.

  That is, the present invention resides in (4) an easy-to-hold chopstick as described in (1) or (2) above, wherein the end face of the flexible synthetic resin tube and the side wall surface of the peripheral groove are in close contact.

  That is, according to the present invention, (5) the peripheral groove is formed at two locations, the portion where the upper portion of the flexible synthetic resin tube abuts and the portion where the lower portion abuts, and the surface of the chopsticks is acceptable. The chopsticks are easy to hold as described in the above (1) or (2), wherein the surface of the flexible synthetic resin tube is flush with the surface thereof.

  That is, the present invention resides in (6) an easy-to-hold chopstick as described in (2) above, wherein a convex portion is formed on the bottom surface of the peripheral groove.

  That is, the present invention resides in (7) an easy-to-hold chopstick as described in (6) above, wherein the convex portion extends over the surface of the flexible synthetic resin tube.

  That is, the present invention resides in (8) an easy-to-hold chopstick as described in (2) above, wherein the flexible synthetic resin tube is colored and translucent, and the heat-shrinkable cylindrical film is visible.

  That is, the present invention resides in (9) an easy-to-hold chopstick as described in (2) above, wherein the flexible synthetic resin tube is made of silicon resin and the heat-shrinkable cylindrical film is made of polyethylene terephthalate resin.

  That is, the present invention resides in (10) an easy-to-hold chopstick manufacturing method in which a peripheral groove is formed in a certain range in the length direction of the chopstick, and then a flexible synthetic resin tube for slip prevention is elastically fixed. .

  That is, the present invention is (11), forming a peripheral groove in a certain range in the length direction of the chopsticks, and then heat-shrinking and fixing a colored heat-shrinkable cylindrical film on the bottom surface of the peripheral groove, On the heat-shrinkable cylindrical film, a colored and translucent flexible non-slip flexible synthetic resin tube is fixed by pressure, and the color of the heat-shrinkable cylindrical film and the color of the flexible synthetic resin tube are mixed. It exists in the manufacturing method of the chopsticks which are easy to hold.

  In addition, as long as the objective of this invention is followed, the structure which combined said (1)-(11) suitably is also employable.

The easy-to-hold chopsticks of the present invention have a peripheral groove in a certain range in the length direction, and a flexible synthetic resin tube for anti-slip is elastically fixed to the bottom surface thereof. The resin tube does not slip or slide off.
In addition, since the flexible synthetic resin tube is positioned in a certain range where the chopsticks are held by hand, an anti-slip effect can be reliably obtained.

The easy-to-hold chopsticks of the present invention have a colored heat-shrinkable cylindrical film heat-shrink fixed to the bottom surface of the peripheral groove, and a colored, light-transmitting flexible non-slip flexible synthetic resin tube. Since the elastic compression is fixed, the color of the heat-shrinkable cylindrical film is transmitted through the flexible synthetic resin tube and mixed with the color of the flexible synthetic resin tube, thereby obtaining a unique color effect.
Moreover, if a character and a pattern are provided to the flexible synthetic resin film, an identification function and a pattern effect can be obtained.
Further, since the bottom surface of the peripheral groove can be hidden by the colored heat-shrinkable cylindrical film, a clearer color effect can be obtained without being affected by the state and color of the chopstick material.
Thus, there is a merit that a unique color effect can be imparted in addition to the difficulty of sliding by skillfully combining the heat-shrinkable cylindrical film and the flexible synthetic resin tube.

The easy-to-hold chopsticks of the present invention have a chopstick surface and a flexible synthetic resin tube surface that are easy to hold when the chopstick surface and the flexible synthetic resin tube surface are flush with each other at the boundary. There is no difference in level, and there is no sense of incongruity such as being caught on the contact portion of the user's hand when used, and there is an advantage that it is easy to use.
In addition, when the end face of the flexible synthetic resin tube and the side wall surface of the peripheral groove are in close contact with each other, no gap is formed, and no dust or dust enters, and it is hygienic and durable.

The peripheral groove of the chopsticks of the present invention, which is easy to hold, is formed at two locations, the portion where the upper portion of the flexible synthetic resin tube abuts and the portion where the lower portion abuts, and the chopstick surface and the flexible portion When the upper and lower portions of the synthetic resin tube surface are flush with each other, the vicinity of the central portion of the flexible synthetic resin tube is appropriately thickened and raised from the chopstick body. Therefore, there is an advantage that it is easy to hold, especially for a child or a person with a disability that does not put power into the hand.
In addition, there is no step between the surface of the flexible synthetic resin tube and the surface of the chopsticks, and there is no sense of incongruity in the hand.
In addition, the peripheral groove is formed in two local areas, which are shorter than the length of the flexible synthetic resin tube, so that cutting at the time of manufacture is also efficient.
Further, there is little decrease in strength.

  When the chopsticks that are easy to hold according to the present invention have a convex portion formed on the bottom surface of the peripheral groove, the heat-shrinkable cylindrical film and the flexible synthetic resin tube can be more securely fixed, Occurrence of wrinkles or the like due to a misalignment can be prevented.

And when the convex part of the bottom face of a peripheral groove has reached the surface of the flexible synthetic resin tube, the unevenness | corrugation of this invention can prevent slipping | slip at the time of use more reliably.
Especially useful for people with thick fingers.

And when the flexible synthetic resin tube used for the chopsticks that are easy to hold of the present invention is made of silicon resin, it has an appropriate elasticity, so that it can be easily expanded and fitted into the chopsticks. After being inserted, the elasticity prevents the chopsticks from slipping and slipping out.
In addition, the anti-slip effect when holding chopsticks that are easy to hold due to the surface frictional force can be obtained. Furthermore, there is an advantage that a comfortable soft feeling can be obtained.
On the other hand, it is easy to impart translucency as a flexible synthetic resin tube.

  When the heat-shrinkable cylindrical film used for the chopsticks that are easy to hold according to the present invention is polyethylene terephthalate resin, a variety of colors can be obtained in addition to providing a reliable fixing effect on the chopstick surface due to high heat-shrinkability. There is an advantage that a film can be obtained.

  And, when the chopsticks that are easy to hold according to the present invention is a manufacturing method in which a peripheral groove is formed in a certain range in the length direction of the chopsticks, and then a flexible synthetic resin tube for slip prevention is elastically fixed, Since the chopsticks that are easy to hold can be obtained simply by fitting the flexible synthetic resin tube into the peripheral groove, there is an advantage that it is extremely simple and does not require an adhesive or other members, and can be reduced in cost.

The chopsticks that are easy to hold according to the present invention form a peripheral groove, and then heat-shrink and fix a colored heat-shrinkable cylindrical film on the bottom surface of the peripheral groove, and then color the heat-shrinkable cylindrical film on the heat-shrinkable cylindrical film. In addition, when the flexible synthetic resin tube for anti-slip having translucency is elastically fixed, the color of the heat-shrinkable cylindrical film and the color of the flexible synthetic resin tube are mixed, The manufacturing can be carried out in the order of peripheral groove formation, heat shrink fixing of the heat shrinkable cylindrical film, and elastic pressure fixing of the flexible synthetic resin tube, which is simple and does not require time.
In addition, the color of the heat-shrinkable cylindrical film provided in advance and the color of the light-transmitting flexible synthetic resin tube can be used to color the surface of chopsticks that are easy to hold, such as special coloring processes and paints. It is very economical without the need for materials.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(First embodiment)
The chopsticks 1 that are easy to hold in the present embodiment, as shown in the manufacturing process explanatory diagram of FIG. 1A, leave a head 11 of a certain length and have a certain range when holding the chopsticks, for example, in the hand. A peripheral groove 2 having a certain depth is formed in the contacting portion.
The portion of the chopsticks in which the peripheral groove is formed, that is, the shape of the peripheral groove shaft 25 is basically a round cross section.
For example, when the chopstick body has a quadrangular cross section, the peripheral groove shaft 25 may have a shape corresponding to the cross section of the chopstick body, such as a quadrangular shape.

A heat-shrinkable cylindrical film 3 and a flexible synthetic resin tube 4 are sequentially fitted and fixed in the peripheral groove 2.
At this time, the heat-shrinkable cylindrical film 3 is heat-shrinked and fixed to the peripheral groove 2 by heat treatment, and the flexible synthetic resin tube 4 is elastically pressed and fixed onto the heat-shrinkable cylindrical film 3.
Specifically, as can be seen from the external view of FIG. 1B and the partial cross-sectional explanatory diagram of FIG. 2, the heat-shrinkable cylindrical film 3 inserted into the peripheral groove 2 is thermally contracted by heat treatment, and the bottom surface of the peripheral groove. 21 is heat-shrink fixed.
A non-slip flexible synthetic resin tube 4 is elastically fixed on the heat-shrinkable cylindrical film 3.

For elastic fixation, the flexible synthetic resin tube 4 (for example, made of silicone resin) has an appropriate stretchability, and as shown by a two-dot chain line in FIG. The synthetic resin tube 4A is fitted into the peripheral groove 2.
The inserted flexible synthetic resin tube 4 is elastically fixed to the bottom surface 21 of the peripheral groove by its elasticity.

Since the depth of the peripheral groove 2 is formed so as to overlap the heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4, the surface of the flexible synthetic resin tube as shown in the cross-sectional explanatory view of FIG. 41 and the chopstick surface 13 are flush with each other at the boundary 44 thereof.
The heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4 are surely stored in the peripheral groove 2 and do not slip and slip.
Further, when the end face 42 of the flexible synthetic resin tube 4 and the peripheral groove side wall face 22 are in close contact with each other, a gap is not generated and dust and dust do not enter and it is hygienic.
Since there is no step between the chopstick surface 13 and the flexible synthetic resin tube surface 41, it is easy to use without being caught during cleaning or during use.

  For example, when the cross section of the chopstick body is a quadrangle and the cross section of the peripheral groove shaft 25 is a round shape, a part of the square corner of the chopstick body is formed at the boundary 44. Although it comes out slightly from the flexible synthetic resin tube surface 42, such a slight coming-out state is made to be in the same range.

Here, if the depth of the peripheral groove 2 is formed constant, the chopsticks 1 are formed with a gentle taper as a whole, so that the thickness of the peripheral groove shaft 25 is also tapered.
If the heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4 are fitted and fixed to the chopsticks 1 in such a state, the thickness of the peripheral groove shaft 25 is large above the peripheral groove 2 and small below. Become.
As a result, the downward extension of the flexible synthetic resin tube 4 is small, and the thickness increases accordingly. As a result, a slight step may be formed between the flexible synthetic resin tube surface 41 and the chopstick surface 13 below the flexible synthetic resin tube (in the direction of the tip of the chopsticks 1). The thickness of the flexible synthetic resin tube 4 may be absorbed by appropriately narrowing, that is, by appropriately increasing the depth of the peripheral groove 2.

The heat-shrinkable cylindrical film 3 is made of an A-color polyethylene terephthalate resin, exhibits high shrinkability by heat treatment, and is thermally shrink-fixed to the bottom surface 21 of the peripheral groove 2.
A B-color flexible synthetic resin tube 4 is elastically fixed on the heat-shrinkable cylindrical film 3.
The flexible synthetic resin tube 4 is a translucent silicone resin, and the A color of the heat-shrinkable cylindrical film 3 located on the lower side is transmitted, and the two colors A and B are mixed. Creates a mixed color.
In this case, applying the three principles of color (light) enables various color expressions combining the colors of the heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4. Here, the translucency means transparent or translucent, and the transparency may be appropriately selected.

Moreover, if a pattern or a character is attached to the heat-shrinkable cylindrical film 3, the pattern or the character emerges through the light-transmitting flexible synthetic resin tube 4 to provide an identification function in addition to obtaining a design effect. be able to.
By using a colored heat-shrinkable cylindrical film, the surface of the chopsticks can be hidden, and a clearer color effect can be obtained without being affected by the state and color of the chopstick material.

Incidentally, as can be seen from the figure, when the head 11 of the chopstick is held, the peripheral groove is not formed in the vicinity of the head 11, that is, in a certain range from the end of the chopstick.
That is, a portion not covering the flexible synthetic resin tube 4 is provided in the vicinity of the head 11.
Normally, when using chopsticks, the chopstick head 11 (particularly the chopstick head 9 located on the upper side of the two chopsticks) moves up and down, but does not cover the flexible synthetic resin tube 4. Because there is a part, even if it touches the finger, it does not interfere with the movement of the shake. Therefore, it is easy to use.
In particular, when using chopsticks, a person with a heel grabbing a position away from the tip, that is, a portion close to the head, has a great effect because the vicinity of the head 11 easily hits the finger.
In addition, when the user holds the chopsticks, the chopsticks are unconsciously rotated or moved back and forth to adjust the position of the chopsticks to a convenient position. At this time, only the head 11 of the chopsticks 1 is slippery. Adjustment is easy and convenient.
The length of the head 11 may be appropriately determined according to the appearance and balance of the chopsticks 1 that are easy to hold.
In addition, an infant or the like may use two easy-to-hold chopsticks 1 in a single state and use them like a fork. The frictional force does not shift each other, and the chopsticks are stabilized when gripped.

(Second Embodiment)
In the present embodiment, as shown in the partial cross-sectional explanatory diagram of FIG. 3, the peripheral groove 2 is provided at two locations only at the locations at the upper portion 43 and the lower portion 43 of the flexible synthetic resin tube 4.
The depth is such that when the heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4 are overlapped and fitted into the chopsticks 1, the flexible synthetic resin tube surface 41 is just flush with the chopstick surface 13. It is.
Moreover, the two surrounding grooves 2 and 2 have the inclined surface 23 inclined toward the inner direction, and gently reach the chopstick surface 13.
In this way, the flexible synthetic resin tube 4 is connected to the chopstick surface 13 in a natural curve by the end face 42 of the upper part 43 and the lower part 43 abutting against the peripheral groove side face 22.
The easy-to-hold chopsticks 1 configured in this manner are inflated when the handle is held, and are easy to use for children and people with low holding power.

(Third embodiment)
In the present embodiment, as shown in the partial cross-sectional explanatory diagram of FIG. The convex portion 24 may have any shape, but is formed in a spiral shape in the present embodiment.
Thus, when the heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4 are fitted and fixed in the peripheral groove 2 having the convex portion, the heat-shrinkable cylindrical film 3 follows the shape of the convex portion 24. It is heat-shrinkable and fixed in shape, increasing the frictional force and preventing it from shifting.
If the flexible synthetic resin tube 4 is fitted on this, the flexible synthetic resin tube 4 is reliably elastically fixed by the convex part 24 exposed on the surface of the heat-shrinkable cylindrical film 3. As shown in the cross-sectional explanatory view, if the shape of the convex portion 24 is reduced, the shape of the convex portion 24 does not reach the surface of the flexible synthetic resin tube 4.

Next, as shown in the partial cross-sectional explanatory diagram of FIG. 6, if the shape of the convex portion 24 is increased, the shape can be extended to the flexible synthetic resin tube surface 41.
If the convex part 24 reaches the flexible synthetic resin tube surface 41, it has an effect of stopping when it is held and further improving the holding power.
FIG. 7 shows an example of the chopsticks 1 when the shape of the convex portion is different from that of FIG.
Since the convex portion 24 is formed in a wave shape and the shape extends to the surface 41 of the flexible synthetic resin tube, this also improves the holding force.

Although the present invention has been described above, the present invention is not limited to the embodiments only, and various modifications are possible unless the gist is changed.
For example, the shape of the chopsticks used in the present invention is not limited to a quadrilateral shape, but may be a round shape, a triangular shape, or a polygonal shape. It is.
The colors of the heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4 are not limited.

Further, the heat-shrinkable cylindrical film 3 used as the base does not need to be spread over the entire surface of the peripheral groove 2, and can be used with a short length or a gap depending on the purpose.
Furthermore, other materials can be used for the material of the heat-shrinkable cylindrical film 3 and the flexible synthetic resin tube 4 as long as the object of the invention is met.

In the chopsticks according to the present invention, a flexible synthetic resin tube for preventing slipping is elastically fixed to at least the bottom surface of a peripheral groove formed in a certain range in the length direction of the chopsticks. There is no slipping or slipping out, and an anti-slip effect can be reliably obtained.
Furthermore, a colored heat-shrinkable cylindrical film is heat-shrink-fixed on the bottom surface of the peripheral groove, and a colored non-slip flexible synthetic resin tube having a light-transmitting property is elastically fixed thereon. There is an advantage that the color of the shrinkable cylindrical film is transmitted through the flexible synthetic resin tube and the color of the flexible synthetic resin tube is mixed to obtain a unique color effect.
As long as such an effect is expected, it can be applied to kitchenware handles, household goods such as umbrellas, canes, clothes racks, sports-related products such as fishing rods, or handrails for stairs. It can be used well for various building components.
