Description

  The present invention is a sealing tool for sealing a transport or storage container, the sealing tool is integrally molded with a synthetic resin that can be known that the sealing tool is broken when the container is opened and the container is opened, and the sealing Related to transport or storage containers.

  When transporting a transport container such as cardboard or synthetic resin, a sealing tool is used to seal the lid of the transport container (see, for example, Patent Document 1).

  In FIG. 10, the sealing tool 1X of patent document 1 is shown. The sealing tool 1X has a flat head portion 2X and an insertion portion 3X protruding downward from the head portion 2X. The tip of the insertion part 3X is formed in a twisted shape. The sealing tool 1X performs sealing by inserting the insertion portion 3X into a through hole 15 formed in the container 16.

  When the container 16 sealed with the sealing tool 1X is opened, the sealing tool 1X is surely destroyed. Therefore, this fact can be known when the container 16 is opened during transportation or storage. This is particularly important for enhancing safety when transporting foods and the like. Hereinafter, the container in the present specification refers to a container that requires sealing, including a transport container or a storage container.

  However, the sealing tool 1X described in Patent Document 1 has several problems. First, as shown in FIG. 10, when the sealing tool 1X is inserted into the through hole 15 of the container 16, there is a problem that the connecting portion 5X that connects the head portion 2X and the insertion portion 3X may be broken. Have.

  When the sealing tool 1X is inserted into the container 16, an operator who performs sealing needs to apply a straight force from the axis of the insertion part 3X to the axial direction of the insertion part 3X. However, in the actual work of the sealed tube, a force is often applied in a direction other than the axial direction of the insertion portion 3X as indicated by an arrow S4 in FIG.

  Thus, the force not applied in the axial direction of the insertion portion 3X becomes a force (arrow S5) for pressing the head portion 2X against the container 16 as shown in FIG. 11, and the force for pressing the insertion portion 3X into the through hole 15 It will not be. Therefore, the thin connecting portion 5X connecting the head portion 2X and the insertion portion 3X is broken, and the sealing tool 1X cannot be used (it must be discarded). The thin connection portion 5X is configured to be very easily broken.

  Second, since the insertion portion 3X has a prismatic shape, it is necessary to match the orientation when the sealing tool 1X is inserted into the through hole 15. For this reason, it has the problem that the operation | work which attaches the sealing tool 1X in large quantities for a short time is difficult.

  This problem can be solved by changing the insertion portion 3X to a cylindrical shape. However, when the insertion portion 3X is a cylindrical shape, it is necessary to form a large connecting portion for supporting the insertion portion 3X. .

  Third, when a force in the pulling direction and twisting direction is applied to the head 2X to break the connection portion and release the sealing, this connection portion remains as a burr on the insertion portion 3X side, and the insertion portion 3X penetrates. There is a problem that it cannot pass through the hole 15. That is, unless the insertion portion 3X is removed from the through hole 15, the sealing of the container 16 cannot be released.

  For this reason, it takes time and effort to release the seal. In particular, this burr becomes a big problem when the connecting portion is formed thick in order to prevent breakage of the connecting portion when the sealing tool is inserted. Originally, it is desirable that no burrs remain in the insertion portion 3X, and at the same time as the head 2X is removed, the insertion portion 3X falls from the through hole 15 and is removed.

  From the above problems, when sealing the container 16, the sealing tool 1X is consumed more than necessary. Moreover, it takes time and effort to seal the container 16 and to release the seal. For this reason, there is a problem that the transportation cost is excessive.

  Below, the sealing tool of embodiment which concerns on this invention is demonstrated, referring drawings. FIG. 1 shows a sealing tool 1, which has a head 2 and an insertion part 3. The head 2 has an annular frame-shaped portion 4, a plurality of connection portions 5 extending from the frame-shaped portion 4 in the center direction, and a flat plate-shaped display portion 6 extending laterally from the frame-shaped portion 4. .

  More specifically, the insertion portion 3 has a shaft portion 11 connected to the head portion 2 via the connection portion 5 and an arrowhead portion that protrudes upward from below the shaft portion 11 and has a repulsive force. is doing. A protruding portion 7 having a height protruding above the head 2 is formed at the upper end of the shaft portion 11.

  The head 2 has a frame-shaped portion 4 having a space in the center and a plurality of connecting portions 5 extending from the frame-shaped portion 4 toward the center. The shaft portion 11 of the insertion portion 3 described above is formed inside the frame-like portion 4 and connected to the plurality of connection portions 5, and the plurality of connection portions 5 are directed from the frame-like portion 4 toward the shaft portion 11. It is formed into a thin wall that becomes thinner.

Note that the frame-like portion 4 may be formed of a rectangular frame-like portion. Further, the shaft portion 11 is desirably formed so as to be arranged at the center of the frame-shaped portion 4, but may be formed at another location as long as it is inside the frame-shaped portion 4. Furthermore, the head has a frame-shaped portion 4, a connection portion 5, and a flat-plate-shaped display portion 6 that extends laterally from the frame-shaped portion.

  In addition, the shaft portion 11 is formed in a columnar shape, and a streak-like rib 9 is provided along the outer periphery of the shaft portion 11 so that the horizontal section of the shaft portion 11 has a petal shape. . In addition, the sealing tool 1 is integrally molded with a synthetic resin.

  Here, when the arrowhead 8 passes through the through hole 15 of the container 16, the arrowhead 8 is deformed and closed so as to pass through the through hole 15. Then, after passing through the through-hole 15, the arrowhead 8 is expanded by an elastic force, and the sealing tool 1 is fixed to the through-hole 15. In addition, the arrowhead part 8 of FIG. 1 is comprised so that the expansion direction may become the same as the longitudinal direction of the display part 6. FIG.

  Moreover, the number of the connection parts 5 can be comprised by arbitrary numbers of 2, 3, 4, or more. Further, the rib 9 has a function of reducing contact resistance between the shaft portion 11 and the container 16 and facilitating insertion of the sealing tool 1 into the through hole 15. In addition, arbitrary characters and figures such as company trade marks can be displayed on the display unit 6.

  FIG. 2 shows a state in which the head 2 and the insertion portion 3 of the sealing tool 1 are broken, and shows a state in which the connection portion 5 and the shaft portion 11 are broken. This is the state when the seal is released.

  FIG. 3 shows a state of the sealing work, and is a side view when the sealing tool 1 is inserted into the through hole 15 of the container 16. The expanding direction of the arrowhead unit 8 is configured to be a direction intersecting with the longitudinal direction of the display unit 6.

  During this sealing operation, the operator applies a force to the sealing tool 1 with a finger, but it is desirable to apply a force that is straight from the axis of the insertion portion 3 in the axial direction. However, when it is necessary to perform the sealing work quickly, it is not possible to carefully check where the force is applied. Therefore, the operator often applies a force to a place shifted from the axis of the insertion portion 3 as indicated by an arrow S1 in FIG.

  Even in such a case, the sealing tool 1 of the present invention is configured such that a force is applied to the protruding portion 7. Therefore, even when no force is applied on the axis of the insertion portion 3, force is transmitted to the insertion portion 3 (in the direction of arrow S <b> 2) and the insertion portion 3 is inserted into the through hole 15 as shown in FIG. 4. Acting as a force (arrow S3).

  That is, in the conventional sealing tool 1X, the operator's force is applied to the head 2X, the insertion portion 3X receives a reaction force from the through hole 15, and the two forces concentrate on the connection portion and break. I was waking up. On the other hand, in the sealing tool 1 of the present invention, the operator's force is directly transmitted from the protruding portion 7 to the shaft portion 11, and no force acts on the head 2. Therefore, no force is applied to the connecting portion 5, and a situation where the sealing tool 1 is broken does not occur.

  In addition, as shown in FIG. 4, the part which connects the frame-shaped part 4 and the display part 6 is formed thinly. With this configuration, for example, when the operator pushes the protruding portion 7 with a thumb or the like while holding the display unit 6 with a finger, the sealing unit can be supported by the display unit 6 and the workability of the sealing operation is improved. be able to. Moreover, since the place formed thinly becomes thin, force is not applied to the connection part 5, and destruction of the sealing tool 1 can be prevented.

FIG. 5 shows a cross-sectional view of the frame-like portion 4 and the connecting portion 5 constituting the head portion 2, and the protruding portion 7 and the shaft portion 11 constituting the insertion portion 3. The head portion 2 and the insertion portion 3 are connected to each other. Indicates the state of Similarly,
FIG. 6 shows a cross-sectional view of the state in which the head 2 and the insertion portion 3 are broken.

  Here, the connection portion 5 is formed in a thin shape that becomes thinner from the frame-shaped portion 4 toward the shaft portion 11, and the place where the connection portion 5 becomes the smallest (the cross-sectional area becomes smaller) The connection point) is the broken portion 10. The breaking portion 10 is a place where concentrated stress is generated when a force is applied to the head 2 of the sealing tool 1 and the head 2 and the insertion portion 3 are broken. By forming the fracture portion 10 on the side surface of the shaft portion 11, a part (burr) of the connection portion 5 does not remain on the shaft portion 11.

  Furthermore, when the connection part 5 is thin (decrease in cross-sectional area), it is desirable to form it except for the connection part 5 on the side close to the display part 6. This is because, in the sealing release operation performed by pulling up the display unit 6, the connection unit 5 on the side close to the display unit 6 can be almost broken at the breaking portion 10 even when it is not thin.

  With the configuration in which a part of the connection portion 5 is not thin, it is possible to prevent the occurrence of a situation in which all the connection portions 5 are carelessly broken and the head 2 and the insertion portion 3 are separated.

  Moreover, you may form the buildup part 5a in the frame-shaped part 4 side of the connection part 5. FIG. By this build-up portion 5a, the connecting portion 5 can be surely broken at the breaking portion 10. You may form this build-up part 5a in all the connection parts 5. FIG. That is, the formation of the built-up portion 5a increases the cross-sectional area of the connecting portion 5 in the outer peripheral direction, and the cross-sectional area of the fracture portion 10 is relatively small, so that the fracture portion 10 can be broken.

  Furthermore, when forming the build-up part 5a in a part of the connection part 5, it is desirable to form it except for the connection part 5 on the side close to the display part 6. This is because, in the sealing release operation performed by pulling up the display unit 6, the connection unit 5 on the side close to the display unit 6 can be almost broken at the breaking portion 10 even when the built-up portion 5 a is not formed. Because. Incidentally, FIG. 5 shows a state in which the built-up portion 5a is formed on the left side of the drawing and is not formed on the right side.

  In addition, it is desirable to form a recess 12 at the top of the protrusion 7. The operator's finger pushing the projecting portion 7 is attracted to the recess 12 by the recess 12, so that the workability of the sealing operation can be improved.

  In FIG. 7, the example of the cross-sectional shape of the connection part 5 is shown. FIG. 7 shows an example in which a notch portion 13 is formed on the breaking portion 10 side of the connection portion 5. With this configuration, since the cross-sectional area of the fracture portion 10 can be reduced and the strength can be reduced, the fracture portion 10 is fractured when the sealing tool 1 is fractured. Thereby, since the burr | flash etc. of the connection part 5 do not remain in the insertion part 3, the insertion part 3 can be easily removed from the through-hole 15 of the container 16. FIG.

  In addition, A thru | or H have shown the cross-sectional area in each place of the connection part 5. FIG. The location B where the build-up portion 5a is formed has a larger cross-sectional area than the location G where the build-up portion 5a is not formed. Further, the cross-sectional areas are the smallest at the locations D and E that become the fractured portion 10. In this case, when the connection between the head 2 and the insertion portion 3 is released (sealing release), the place with the smallest cross-sectional area is broken. For this reason, the cross-sectional areas of the places D and E closest to the shaft portion 11 are made small so as not to leave burrs, and the rupture portion 10 is formed.

  FIG. 8 shows a state when the sealing tool 1 is installed in the container 16 and the sealing work is performed. The sealing tool 1 protrudes from the container 16 and can be installed so that the display part 6 does not protrude to the outside after the sealing work so that the sealing tool 1 does not come into contact with other containers 16 and the like. This is made possible by changing the shaft portion 11 from a conventional prismatic shape to a cylindrical shape. When the container 16 is transported, it is desirable to install a substantially U-shaped fixing tool 17 in order to prevent an accident that the sealing tool 1 is weighted and broken.

  FIG. 9 shows a cross-sectional view of the container 16, FIG. 9A shows the container 16 in which the sealing tool 1 is installed, and FIG. 9B shows the container 16 in which the fixing tool 17 is installed. FIG. 9A shows a state in which the sealing tool 1 is inserted and sealed in a through hole 15 provided so as to penetrate the main body and lid of the container 16. Here, in order to release the sealing, for example, the display unit 6 of the sealing tool 1 is torn upward and the insertion unit 3 is removed from below the through hole.

  In addition, it is desirable to form the enclosure wall 18 which encloses the arrowhead part 8 of the sealing tool 1 in the container 16. The enclosure wall 18 can prevent unjust actions such as closing the arrowhead 8 with radio pliers or the like and pushing it up and removing the sealing tool 1 from the container 16 without destroying it.

  Further, when the sealing tool 1 is pulled upward, the arrowhead 8 may turn up and open downward. At this time, the sealing tool 1 may be removed from the container 16 without being destroyed. The turning of the arrowhead 8 can be prevented by the surrounding wall 18.

  FIG. 9B shows an example of a fixture 17 that fixes the main body and lid of the container 16 together. The fixture 17 is rotatably fixed to the main body of the container 16 and is configured to hold down the lid. This fixing tool 17 can prevent an accident that the main body of the container 16 and the lid body are displaced and a force is applied to the sealing tool 1 to release the sealing.
