Abstract

PURPOSE: To provide a sealing tool for a transporting container which can not be unsealed unless it is broken, when it is sealed once. CONSTITUTION: A sealing tool is constituted of a belt 1 and a plurality of inserts 3 projected to the lower side of the belt. The insert 3 is composed of leg 3a and a plurality of fixing pieces 3b diagonally protruded upward from the front end of the leg 3a to form an arrow head-shape and the fixing piece 3b has an elastically repellent force and a plurality of opened cut holes 2a in the belt 1 at the root of leg 3a. The sealing tool is made of a plastic and molded as a unit. In this way, when the insert is once put into the closing hole for the transporting container the insert can never be pul led out of the hole of container even if one tries to pull it out, because the fixing piece prevents it from coming out. But, the sealing tool can be easily unsealed by tearing off the belt to separate the insert.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container sealing tool that cannot be opened without destroying a shipping container such as a cardboard box once it is sealed.

[0002]

2. Description of the Related Art When a cardboard box or a plastic box is used as a shipping container for goods, it is common to close the unsealed portion after the goods are stored and attach the closed portion with gum tape to seal the goods. is there. However, if you repeatedly use it as a container that passes through a cardboard box, etc., if you seal it with gum tape, it takes time to peel off the gum tape and open it,
When peeling off the tape, the cardboard box is damaged and cannot be reused. Therefore, in such a case, the transportation container is repeatedly reused by using a sealing means such as binding with a string or a heat-sealing belt, attaching buttons on both sides of the closed portion, and winding a thread around the button. are doing.

[0003]

However, when the transportation container is sealed by using the reusable sealing means, it can be easily resealed by using the same sealing means after once opening the container. Therefore, it is vulnerable to unloading during transportation or storage, and even if there is a discrepancy in the number of deliveries between the shipping side and the receiving side, that discrepancy will not occur during packaging, transportation, or storage. There is a problem that it is difficult to find out the cause of the problem at the stage.

Therefore, the present inventor has examined a plastic sealing means as a simple sealing means. This is one in which a barbed insertion portion is formed on one surface of the belt-shaped portion, and the base portion of the insertion portion is made thin so that it can be easily broken at the time of opening, but this has the following problems. That is, when the insertion part is inserted into the hole provided in the lid part of the shipping container at the time of sealing, the root part of this insertion part is easily damaged, so there is a problem that the sealing work must be done carefully. . In addition, the shipping container that has been sealed may be handled roughly or stacked up, but in this case, the sealing device may be broken and may be opened.

Therefore, instead of making the root portion of the insertion portion thin, one cutting hole is formed in the width direction of the strip portion at the side of the root portion of the insertion portion of the strip portion, and the strip portion is torn off when opening. I tried to configure it to. According to this, damage does not occur when inserting the insertion part into the hole provided in the lid part of the shipping container, but after tearing off the band part at the time of opening, the remaining piece of the band part adheres to the insertion part side, There was a problem that the insertion part could not be pulled out from the hole due to the remaining pieces and the mess, which hindered the reuse as the sealing container.

According to the present invention, when the container is sealed, the sealing operation can be easily performed without tearing from the root of the insertion portion, and the sealed container can be securely held even if it is handled roughly. At the same time, it is an object of the present invention to provide a plastic closure that can be easily opened at the time of opening, and the insertion part can be easily removed from the hole of the lid of the container to reuse the container.

[0007]

In order to solve the above problems, the closure of the present invention comprises a strip-shaped portion and a plurality of insertion portions protruding from the lower surface of the strip-shaped portion. Is formed of a leg and a plurality of locking pieces that project obliquely upward from the tip of the leg to form a barbed shape, and the locking piece has elastic force and is A plurality of cutting holes are opened in the belt-like portion of the root portion and integrally formed with plastic.

The strip-shaped portion is a flat thin plate shape and is configured so as not to be caught and destroyed even when other containers are stacked on the closure. Although a plurality of cutting holes are opened in the belt-like portion at the root of the leg, it is preferable that three or more cutting holes are arranged around the root and arranged at average intervals. As the plastic used in the closure of the present invention, for example, ABS resin, vinyl chloride resin, polypropylene, polyethylene or the like is used.

[0009]

[Operation] In the above-mentioned closure, when the insertion part is inserted from the tip of the leg into the hole in the closed part of the container such as the lid of the shipping container, the locking that was opened like a jar from the tip of the leg The piece can be folded in the direction of the leg to pass through the hole, and once it passes through the hole, the locking piece immediately returns to its original shape and opens like a mess, and the insertion part should be pulled out from the hole of the container. Even then, the locking piece interferes and it becomes impossible to remove it. Then, unless the root of the insertion portion is broken by pulling the band-shaped portion, the container cannot be opened without damage, and the container can be sealed. Also, the band-shaped portion can be torn off to separate the insertion portion, and the opening can be easily opened.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A closure 1 according to this embodiment will be described with reference to FIGS. The closure 1 of the present embodiment is manufactured by integrally molding a flexible plastic such as ABS or vinyl chloride, and has a flat thin plate-shaped band 2 and two insertions protruding from the lower surface of the band 2. It consists of part 3.

The insertion portion 3 includes a leg portion 3a and the leg portion 3a.
Two locking pieces 3b projecting diagonally upward from the tip of the
And is constructed like a finger pointing downwards as a whole. Then, a thin portion 3d is formed by providing a recess 3c at the boundary between the locking piece 3b and the leg portion 3a, and the thin portion 3d is provided with flexibility and resilience, and the locking piece 3b is fixed to the leg portion. It is configured such that it can be bent in the direction of 3a, and that when the bent locking piece 3b is opened, it can be restored to the original shape of a worm.

Then, in order to cut the insertion portion 3 from its root portion, a plurality of cutting holes 2a are opened in the strip portion 2 of the root portion of the leg portion 3a to weaken the strength of the strip portion 2 of the root portion. ing. As shown in the drawing, the cut holes 2a are arranged around the root of the leg 3a so that three or more, and most preferably four holes are arranged at an average interval, and the holes 2a are weakened on average to an appropriate degree. Moreover, when the strip-shaped portion 2 is torn off at the time of opening, the remaining pieces of the strip-shaped portion 2 hardly adhere to the insertion portion 3 side.

Further, in this embodiment, both end portions and both side portions of the thin plate-shaped band-shaped portion 2 are chamfered so that a smooth inclined surface 2b is formed to have a corner. Then, both sides of the central portion of the strip-shaped portion 1 are notched to leave a corner and the inclined surface 2b is not formed to facilitate gripping, and the gripping portion 2c is formed. If the back surface of the grip portion 2c is shaved to facilitate insertion of a tool such as a claw or a screwdriver, the opening operation can be efficiently performed.

Further, the leg portion 3a is formed in a cross-shaped cross section to increase the sectional modulus of the leg portion 3a to enhance the strength. Next, as shown in FIG. 7, the transportation container 4 used in the present embodiment is a returnable box for storing and transporting finished products such as clothing while hanging them on a hanger (not shown). The pole 4a for suspending is attached to the container 4 in advance, and the front door 4b is rotated in the direction of the arrow to be closed. Then, as shown in FIG. 8, the top plate 4c on the front door 4b side is abutted against the top plate 4d on the main body side of the corrugated cardboard container 4 to be sealed by the sealing device 1 of the present invention.

Further, a procedure for sealing the container 4 with the sealing tool 1 and then releasing the sealing will be described. First, the front door 4b
When the two insertion portions 3 of the closure 1 are inserted into the holes 4e and 4f provided in the top plates (opening portions) 4c and 4d on the side of the body and the body side from their tips, the locking pieces 3b are pushed. It can be inserted by being bent in the direction of the legs 3a. Then, until the strip-shaped portion 2 directly hits the top plates 4c and 4d,
When the insertion portion 3 is inserted into the holes 4e and 4f, the locking piece 3b that has passed through the holes 4e and 4f is released and returns to the original shape like a worm, whereby the insertion portion 3 cannot be pulled out from the holes 4e and 4f. . In this way, the container 4 is simply and reliably sealed.

Next, in order to release the sealing, the grip portion 2c provided at the center of the strip-shaped portion 2 is grasped and torn off, so that the strip-shaped portion 2 is cut at the cutting hole 2a and separated from the leg portion 3a. The insertion part 3 remains in the container 4. In this way, the container 4 is easily unsealed. Moreover, since the cutting holes 2a are arranged in an averaged manner around the base of the leg 3a and opened, the remaining pieces of the belt-shaped portion 2 hardly adhere to the insertion portion 3 side. It can be easily pulled out from 4f.

The sealing member 1 is attached by forming the strip-shaped portion 2 of the sealing member 1 into a flat thin plate shape and chamfering both end portions and both side portions of the strip-shaped portion 2 to form a smooth inclined surface 2b. When handling containers 4 such as putting in and taking out and stacking,
There is no possibility that the belt-shaped portion 2 will be caught and become an obstacle.
Further, since the closure 1 is an integrally molded plastic product having an extremely simple structure as described above, it is easy to manufacture and can be provided at a low price.

[0018]

According to the closure of the present invention having the above-described structure, the container can be simply and surely sealed by inserting the insertion portion into the hole provided in the closed portion of the container, and the closure can be sealed. Since the container cannot be opened without damage unless the container is destroyed, the reliability and safety of storage of articles in the container are improved.

Further, since the base portion of the insertion portion is made thin so as not to be easily broken, it is possible to prevent an accident in which the insertion portion is broken when the insertion portion is inserted into the hole of the closed portion of the container. In addition, when releasing the container sealing, the insertion part can be separated from the root part by pulling on the band-shaped body of the closure, and the container can be easily unsealed, and the insertion part can be inserted from the hole in the closing part of the container. Can be easily removed. Further, since the closure is an integrally molded plastic product having an extremely simple structure, it is easy to manufacture and can be provided at low cost.
