Description

  The present invention relates to an elastic band for binding objects to be bound such as stationery, food, and machine parts.

  Conventionally, when binding objects such as stationery, food, and machine parts, binding tools such as stretchable rubber bands have been used. However, since the binding tool such as a rubber band is formed in an endless ring shape from the beginning, it is easy to wrap it around the object to be bound, but it is necessary to hook or wrap it somewhere when performing winding. In some cases, it was not very convenient.

Therefore, binding tools such as Insulok tie (registered trademark) and cord bands have been developed instead of rubber bands. However, such a binding tool has a relatively complicated structure, and has a disadvantage that it is difficult to reuse after being bound once.
In view of this, as a binding tool that has a simple structure and can be reused, the following is used.

For example, Patent Document 1 discloses a tightening band in which a cord-like elastic band is provided at one end of a string-like elastic band and an annular receiving ring is provided at the other end for inserting and locking the hook. Is disclosed.
Patent Document 2 discloses a stretchable band part, a ring part integrally provided at one end of the band part, and a ring part integrally provided at the other end of the band part. The band portion is made of a thermoplastic elastomer, the ring portion and the mooring protrusion portion are made of a thermoplastic elastomer or a thermoplastic resin, and the hardness of the ring portion and the mooring protrusion portion is determined by a band. A simple binding band set to be equal to or higher than the hardness of the part is disclosed.

  The fastening band of Patent Document 1 and the simple binding band of Patent Document 2 described above are provided with an annular receiving hole at one end of a string part formed in a string shape, and are provided at the other end of the string part in this receiving hole. It has a configuration in which a knot-like latching body and a mooring projection are fitted and bound.

[First Embodiment]
Hereinafter, a first embodiment of an elastic band 1 of the present invention will be described in detail with reference to the drawings.
The stretchable band 1 of the present invention is a binding object B for a food product such as a crop, as in the case of binding a binding material B of a stationery such as a writing instrument, a notebook, or a mechanical pencil lead, or binding a stem of a leafy vegetable. , And furthermore, the mouth of a plastic bag containing processed foods such as pickles is used as an object to be bound B. Further, the elastic band 1 of the present invention binds a binding object B of cables such as a power cord and a LAN cable, and binds a mechanical part, an electrical part, a kitchen article, a laundry article, a gardening article, an agricultural article, and the like. It can also be used for bundling things B together. The stretchable band 1 is formed in an elongated string shape or rod shape using an elastic material, and is configured to be wound around the object to be bound B by being wound around the object to be bound B.

Specifically, as shown in FIG. 1, the elastic band 1 of the first embodiment includes a string part 2 that is extendable in the longitudinal direction, a knob part 3 provided on one end side of the string part 2, and A receiving hole 4 that is formed on the other end side of the string part 2 and that connects the one end side of the string part 2 provided with the knob part 3 to the other end side of the string part 2 by fitting the knob part 3 therethrough. And.
Hereinafter, each member, such as the string part 2, the knob part 3, and the receiving hole 4 which constitutes the elastic band 1, will be described in detail.

  In the following description, the right side (side on which the knob portion 3 is provided) in the front view of FIG. 1 is referred to as one end side or the distal end side when the elastic band 1 is described, and the left side in the front view of FIG. The side on which the receiving hole 4 is formed is referred to as the other end side or the base end side when the elastic band 1 is described. Moreover, the up-down direction in the front view of FIG. 1 is called the left-right direction or the width direction when the elastic band 1 is described. Furthermore, the up-down direction in the plan view (cross-sectional view) of FIG. 1 is referred to as the up-down direction or the thickness direction when the elastic band 1 is described.

  As shown in FIG. 1, the string part 2 is an elongated part made of an elastic material such as rubber or elastomer, and is stretchable in the longitudinal direction. It is set as the structure which can deform | transform. The length and thickness of the string portion 2 are 50 mm to 300 mm in length and 1.0 mm to 5.0 mm in diameter if the above-mentioned daily necessities are to be bound B. The stretchable band 1 of the present embodiment (illustrated example) has a total band length of 150 mm, the string portion 2 has a length of 100 mm, and the string portion 2 has a thickness of 3 mm.

  The elastic material constituting the string portion 2 is made of a synthetic resin such as rubber or elastomer rich in elasticity. As the elastic material forming the string portion 2, it is preferable to use silicon rubber or silicon-based elastomer. If silicon rubber or silicone elastomer is used as the elastic material, it is possible to obtain an elastic band 1 having better heat resistance, chemical resistance, oil resistance, acid resistance, etc. than general thermoplastic synthetic resins. 1 applications (types of bound objects B) can be expanded.

  The elastic band 1 of the present embodiment uses a silicone elastomer (silicon rubber) for the string portion 2, and has a bump 3 other than the string portion 2, a receiving hole 4, and a plate-like portion described later. By using the same elastic material as that of the string portion 2, the elastic band 1 itself is processed as a single body with a silicon-based elastomer. If the elastic band 1 is processed into such an integrated body, the manufacturing process becomes simple, and the manufacturing cost can be kept low.

  The knob portion 3 is a portion formed on one end side (tip side) of the string portion 2 and is a portion that can be connected to the other end side of the string portion 2 by being fitted into the receiving hole 4. In the case of the present embodiment, the knob portion 3 is formed in a shape in which a sphere larger than the diameter of the string portion 2 is slightly crushed. More specifically, the knob portion 3 of the present embodiment is obtained by cutting the above-mentioned sphere at a place about 1/3 of the diameter in the longitudinal direction and separating it into two parts. Only). And the knob | groove part 3 of this embodiment can be connected with the receiving hole 4 so that the rounded part at the front end side may be fitted in the receiving hole 4 mentioned later.

  Further, the above-described knob portion 3 is formed to have a diameter about twice the diameter (outer diameter) of the string portion 2, and a step 3 a can be formed between the string portion 2 and the knob portion 3. . If the step 3a is formed between the knob portion 3 and the string portion 2 in this manner, the step 3a is caught by the hole edge of the receiving hole 4 (as will be described later, the opening diameter of the receiving hole 4 is approximately the string portion 2). Therefore, the fitted knob portion 3 is difficult to be removed from the receiving hole 4.

  Furthermore, a finger hook portion 6 is formed at a position about three times the diameter of the knob portion 3 from the knob portion 3 to the other end side of the string portion 2 so that the finger portion can be easily hooked when the string portion 2 is picked. Has been. Specifically, the finger-hanging portion 6 has a drum shape having an outer diameter of about 1.2 to 1.5 times the diameter of the string portion 2 and a length of about 2 to 5 times the diameter of the string portion 2. It is a part, and the midway side in the longitudinal direction is formed slightly smaller in diameter than both ends. If the finger hooking portion 6 having a diameter larger than that of the string portion 2 is provided, the string portion 2 can be securely gripped even if the string portion 2 is formed to have a small diameter, and the length of the finger hanging portion 6 in the longitudinal direction can be increased. If the halfway side is formed to be slightly smaller in diameter than the both ends, the hooked finger is less likely to slip, so that the knob portion 3 fitted in the receiving hole 4 can be easily pulled out.

  The receiving hole 4 is a hole portion that is perforated to an opening diameter that allows passage of a large-diameter member such as the above-described knob portion 3 but that has a small diameter such as the string portion 2. is there. The receiving hole 4 is formed on the other end side of the string portion 2, and can be connected to the knob portion 3 by pushing the knob portion 3 with a finger or the like to be fitted, and cooperates with the knob portion 3. The telescopic band 1 can be connected in a ring shape (endless shape).

  And the receiving hole 4 mentioned above is the case of the elastic band 1 of this embodiment, and the plate-like part 5 in the edge part of the front end side of the plate-like part 5, in other words, the edge part near the knob part 3 is provided. Is formed so as to penetrate through in the thickness direction. Specifically, the above-described receiving hole 4 is formed in a tapered shape in which a mouth opening on one surface of the plate-like portion 5 and a mouth 4a opening on the other surface are spread outward. Has been. If such a tapered mouth 4a is formed in the receiving hole 4, the knob 3 can easily enter the receiving hole 4, and the knob 3 is engaged with or engaged with the socket 3. It becomes even easier to pull out 3 from the receiving hole 4.

Further, the receiving hole 4 described above is drilled at a position where the center of the receiving hole 4 is positioned on the axis of the center line in the left-right direction of the string portion 2. If the receiving hole 4 is formed in such a position, it becomes possible to engage the expansion-contraction band 1 in the shape of a ring on a track close to a perfect circle without twisting, and to bind the objects to be bound B neatly.
Specifically, a plate-like part 5 wider than the string part 2 is formed on the other end side of the string part 2. That is, the base end side of the plate-like portion 5 with respect to the receiving hole 4 is a projecting piece protruding toward the opposite side to the side on which the string portion 2 is attached across the receiving hole 4. The plate-like part 5 has a dimension that is 3 to 10 times the diameter of the string part 2 in the width direction and a substantially rectangular shape (exactly accurate to a dimension that is 3 to 20 times the diameter of the string part 2 in the longitudinal direction). Is a part formed in a plate shape of a rectangle with rounded corners). Further, the center of the plate-like portion 5 is formed thinner than the outer periphery which is flush with the upper surface of the plate-like portion 5, and a sticker displaying information on the object to be bound B is attached or written. It can be done.

If the plate-like part 5 as described above is provided, it becomes possible to display information on the object to be bound B on the plate-like part 5 or use it as a tag having a writable space. That is, in the present embodiment, the plate-like portion 5 as described above, in particular, the base end side (projection piece) of the plate-like portion 5 is a display portion for displaying information.
For example, when the material to be bound B is a food, the plate-like portion 5 has information on the expiration date, opening date, processing date and time, production / manufacturer, etc. Information such as materials, manufacturers, dimensions, etc. can be displayed and written. The information that can be displayed on the plate-like portion 5 includes price, precautions for handling, advertising, advertisements, and the like. Further, the plate-like portion 5 itself may be processed into a shape such as a mascot or a character instead of a rectangle to enhance the design, and the purchase intention of the purchaser who purchases the bound material B may be stimulated.

When binding the object B to be bound with the above-described elastic band 1, in other words, when connecting both ends of the elastic band 1, the following procedure is performed.
That is, the other end of the elastic band 1 is wound around the object to be bound B in a state where the other end is fixed so as not to move. If it does so, the string part 2 formed with the elastic material will bend and expand | extend freely, and the string part 2 can be wound around the outer periphery of the to-be-bundled object B. At this time, it is preferable that the number of windings of the string portion 2 is a plurality of times. In the case of the present embodiment, the periphery of the long object B is wound three times.

  As shown in the “separated state” in FIG. 5, the string portion 2 wound three times in this way comes to a position where the knob portion 3 and the receiving hole 4 face each other with a little distance. Thus, when the knob part 3 and the receiving hole 4 face each other with a small distance, the knob part 3 is picked with a finger and forcedly brought close to the receiving hole 4. At this time, since the knob part 3, the string part 2, and the receiving hole 4 are formed of an elastic material, each member can be elastically deformed and the knob part 3 can be easily brought close to the receiving hole 4.

  As shown in FIG. 6, when the knob 3 is brought close to the opening of the receiving hole 4, the knob 3 is pushed into the receiving hole 4 with the belly of the finger. If it does so, the knob part 3 and the receiving hole 4 will elastically deform, the knob part 3 will be fitted to the receiving hole 4, and it will become possible to connect the expansion-contraction band 1 in ring shape. FIG. 6 shows an example in which the knob portion 3 is pushed into the receiving hole 4 from above (the front side of the plate-like portion 5), but the pushing direction of the knob portion 3 into the receiving hole 4 is downward (plate-like portion). It may be from the back side of 5).

When the connected elastic band 1 is removed, the finger hook 6 is picked and the string portion 2 is forcibly pulled out. If it does so, it will become possible to remove the elastic band 1 easily.
From the above, according to the elastic band 1 of the present embodiment, the protrusion 3 described above can be grasped with a finger or the like and pressed so as not to escape the receiving hole 4. It can be pushed in, and both ends of the string portion 2 can be reliably connected or removed in a ring shape.
[Second to Fourth Embodiments]
By the way, in 1st Embodiment mentioned above, the example in which the receiving hole 4 was formed in the front end side of the plate-shaped part 5 was given. However, as shown in the second embodiment of FIG. 2, the position of the receiving hole 4 may be formed on the proximal end side of the plate-like portion 5 or a plurality of perforations ( formed on the distal end side of the plate-like portion 5). The first receiving hole and the second receiving hole formed on the base end side may be perforated). In other words, it can also be said that the elastic band 1 of the second embodiment is provided with a display unit for displaying information between the other end of the string unit 2 and the receiving hole 4.

  If the receiving hole 4 is formed on the base end side of the plate-like part 5 as in the second embodiment, the plate-like part 5 is attached to the object to be bound B along the outer surface of the object to be bound B together with the string part 2. It can wind, and it becomes possible to strengthen the binding force of the to-be-bound object B. Moreover, if it is such a winding method, the plate-shaped part 5 will not protrude to the outer side of the to-be-bundled object B, and the binding state will be neat and good-looking.

Even if the receiving hole 4 is perforated on the base end side of the plate-like portion 5, the plate-like portion 5 remains on the base end side of the receiving hole 4 as a picking allowance. 3 is easy to insert, and both ends of the string portion 2 can be reliably connected or removed like a ring as in the first embodiment.
Moreover, in 1st Embodiment mentioned above, the example which made the plate-shaped part 5 substantially rectangular shape was given. However, as shown in the third and fourth embodiments of FIGS. 3 and 4, the shape of the plate-like portion 5 may be substantially circular. If the plate-like part 5 is formed in such a circular shape, the area of the plate-like part 5 becomes large, and it becomes easy to display characters and the like.

Summarizing the above, the elastic band of the present invention is formed on the other end side of the string portion, the string portion that is stretchable in the longitudinal direction, the knob portion provided on one end side of the string portion, and And a receiving hole for connecting one end side of the string part provided with the knob part to the other end side of the string part by fitting the knob part, so that the knob part can be pushed into the receiving hole, At least one of the knob portion and the receiving hole is formed of an elastic member, and the opening diameter of the receiving hole is formed to be smaller than the outer diameter of the knob portion so that the fitting knob portion can be prevented from coming off from the receiving hole. In the side of the receiving hole, a projecting piece (plate-like part 5) is formed that protrudes toward the opposite side of the string part (the side to which the string part is attached) across the receiving hole. It is characterized by this.

  Preferably, a side of the protruding piece close to the receiving hole is formed in a plate shape wider than the string portion. The projecting piece formed in a wide plate shape is preferably used as a display unit for displaying information. Preferably, the side close to the receiving hole in the string portion is formed in a plate shape wider than the middle side in the longitudinal direction, and the receiving hole is formed on the other end side of the portion formed in the plate shape. It is good to be. In this case, the space between the other end of the string portion and the receiving hole can be used as a display portion for displaying information.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
