Description

  The present technology relates to a stopper in a packaging box such as a cardboard box.

Packing boxes such as cardboard boxes are widely used and are indispensable in the field of logistics and the like.
The packaging box is used as a transport box for efficiently transporting articles, or used as a storage box for storing things.

  In the above-described application, the packaging box must be taken in and out. At that time, the flap portion of the packing box obstructs the work, and the work efficiency is lowered.

In order to solve the above-described problem, a stopper for temporarily fixing the flap in a state where the flap is bent outward has been proposed (see, for example, Patent Document 1 and Patent Document 2).
Moreover, when sealing a packaging box, sealing with a tape is often used, but in this case, the surface of the packaging box is damaged.

  In order to solve the above-described problem, a sealing tool different from a tape has been proposed (for example, see Patent Document 3).

However, in the stopper described in Patent Document 1, the shape of the stopper is complicated, resulting in problems of productivity and cost. Furthermore, even if the flap portion can be temporarily fixed, it cannot be used as a sealing tool.
Moreover, in the stopper described in FIG. 1 of Patent Document 2, provisional fixing is not possible when the packaging box is different from the size of the stopper, so a plurality of stoppers that match the size of the packaging box are prepared. There is a problem that it is necessary or the shape of the stopper is large and the storage property is insufficient.
Furthermore, in the stopper described in FIG. 3 of Patent Document 2, the temporary fixing operation is not simple and requires time, so that the work efficiency is lowered. In addition, the stopper described in Patent Document 2 cannot be used as a sealing tool even if the flap portion can be temporarily fixed.
Furthermore, in the sealing tool described in Patent Document 3, the shape of the sealing tool is complicated, resulting in problems of productivity and cost. Furthermore, although it can be used as a sealing tool, it cannot be used as a temporary fixing of the flap portion.

  Therefore, the packing box stopper according to the present technology has a problem that the work time generated by performing the temporary fixing work reduces the work efficiency, the problem that productivity and cost deteriorate due to having a complicated structure, and the stopper. It is an object to solve the problem that the size of the box depends on the size of the packaging box and the problem that the jig as a temporary fixing of the flap portion and the jig as a sealing tool cannot be combined.

<1. First Embodiment>
Hereinafter, the best mode for carrying out the present packaging box stopper will be described with reference to the accompanying drawings.
[1-1. Structure of packing box stopper]
First, a first embodiment of a packing box stopper will be described (see FIGS. 1A and 2A). Here, a stopper for a packaging box having one clamping unit will be described.

The packaging box stopper 1 according to the first embodiment has one clamping unit 7.
The sandwiching unit 7 includes a pair of sandwiching portions 2 and 2 that are formed in a substantially rectangular parallelepiped shape and arranged to face each other, and a connecting portion 3 that connects only one end portion in the longitudinal direction of the pair of sandwiching portions 2 and 2. That is, the entire shape of the packing box stopper 1 is substantially U-shaped or substantially U-shaped as if a single rectangular parallelepiped is bent at the center.

  Since the structure of the packing box stopper 1 is the above-described simple structure, it can be easily molded.

  The tip portions 4 and 4 of the pair of sandwiching portions 2 and 2 have tapered surfaces 4a and 4a, respectively, which are subjected to taper processing so that the inner surfaces thereof are displaced in a direction away from each other toward the tip. The corners of the front end portion 4 of the sandwiching portion 2 are formed, for example, as rounded corner portions 4b and 4b that are chamfered in order to improve safety during use.

  The inner surfaces excluding the tapered surfaces 4a and 4a of the pair of sandwiching portions 2 and 2 are formed as inner surfaces 2a and 2a substantially parallel to each other. For example, the distance D1 between the inner surfaces 2a and 2a is the maximum thickness of the sandwiching portion 2 It is approximately twice D2 (see FIG. 2A).

  Further, the maximum thickness D2 of the sandwiching portion 2 has only a minimum strength in preparation for the case where the packing box stopper 1 is used as a temporary fixing jig for the flap portion 101 and as a sealing jig. It has been made thin.

The packaging box stopper 1 is manufactured by integral molding with a resin (for example, polypropylene or the like) or by bending with a metal.
According to the above manufacturing method, molding is easy and the manufacturing cost can be kept low.

[1-2. Usage form as a temporary fixing jig for the flap of the packaging box]
Hereinafter, a method of using the packing box stopper 1 as a temporary fixing jig for the flap portion 101 of the packing box 100 will be described (see FIGS. 3 to 5).

The flap part 101 of the packaging box 100 includes four flaps 101a, 101b, 101c, and 101d.
First, the front flap 101d that hinders work when a package is taken in and out of the packaging box 100 is bent to the outside of the packaging box 100 (see FIG. 4A).

  Next, the packing box stopper 1 is fitted from above so as to sandwich both the folded flap 101d and the side wall 102 of the packing box 100 (see FIGS. 4B to 5). At this time, the connecting portion 3 of the packing box stopper 1 is elastically deformed so as to be displaced in a direction in which the pair of sandwiching portions 2 and 2 are separated from each other. As a result, the single flap 101d can be temporarily fixed as shown in FIG. 3A.

  Since the series of operations described above are simple operations that do not require complicated operations, the operations can be performed efficiently without deteriorating the work efficiency due to the temporary fixing operation. In addition, by taking this state, the work for putting in / out the articles to / from the packaging box 100 is facilitated.

  Moreover, since the front end portions 4 and 4 of the clamping portions 2 and 2 of the packing box stopper 1 have tapered surfaces 4a and 4a that are tapered, the packing box stopper 1 is temporarily fixed. It is easy to insert and remove when used as a jig.

  Furthermore, since the packing box stopper 1 is substantially U-shaped or substantially U-shaped, and the space between the holding portions 2 and 2 is open in the short direction, the flap of the packing box 100 When the portion 101 and the side wall 102 are fitted, the jig can be used as a temporary fixing jig without depending on the size of the packaging box 100.

  Further, in the above-described usage method, one packing box stopper 1 is used. However, in order to temporarily fix a plurality of flaps 101a, 101b,... Stoppers 1, 1,... May be used.

[1-3. Usage as packing jig sealing tool]
Next, a method of using the packing box stopper 1 as a sealing jig for the packing box 100 will be described (see FIGS. 6A, 7 and 8).

  First, the flaps 101a and 101b protruding from the longitudinal ends of the packaging box 100 are bent inside the packaging box 100 so as to be approximately 90 ° (see FIG. 7A).

  Next, the flaps 101c and 101d projecting from the end of the packaging box 100 in the short direction are folded inside the packaging box 100 so as to be approximately 90 °. The above is a normal packing procedure for packing cardboard or the like.

  Next, the packaging box stopper 1 is fitted from the longitudinal direction of the packaging box 100 so as to sandwich the corners of the flap 101c and the flap 101d of the packaging box 100 (see FIG. 7B).

  Although the case where one packing box stopper 1 is used as a sealing jig has been described, two packing box stoppers 1 and 1 are used, and the packing box stopper is used from both ends in the longitudinal direction of the packing box 100. The tools 1 and 1 may be fitted (see FIG. 8).

  The series of operations described above are simple operations that do not require complicated operations because the packing box stopper 1 is simply inserted from the longitudinal direction of the packaging box 100 after the normal corrugated cardboard flap folding operation. The work can be performed efficiently without deteriorating the work efficiency due to the stop work.

[1-4. Another form of use as a packaging box sealing jig]
Next, another method of using the packing box stopper 1 as a sealing jig for the packing box 100 will be described (see FIGS. 9 to 11).

  First, the flap part 101 of the packaging box 100 is bent inward. The flap portion 101 includes four flaps 101a, 101b, 101c, and 101d. The flap 101a (see FIG. 9A), the flap 101d (see FIG. 9B), the flap 101b (see FIG. 10A), and the flap 101c are bent in this order. (See FIG. 10B). The packing box stopper 1 is fitted into the portion where the flap 101b and the flap 101c overlap (see FIG. 11).

  The folding order of the flap portion 101 of the packaging box 100 described above is merely an example, and the packaging box stopper 1 can be used as a sealing jig for the packaging box 100 even when folded in a different order.

  When the packing box stopper 1 is used as a sealing jig for the packing box 100, the maximum thickness D2 of the clamping part 2 of the packing box stopper 1 is reduced, so that the packing boxes 100, 100,.・ ・ Stable stacking becomes possible.

  As a general sealing method that does not use a stopper, there is a method in which flaps 101a, 101b, 101c, and 101d are overlapped with each other. That is, there is a method in which a part of the flap 101c is submerged under the flap 101a from the state of FIG. 10B, but the durability of the packaging box 100 is likely to be lowered due to the folding of the flap 101c or the flap 101a, and the operation is easy. There is also a problem with sex. If the packing box stopper 1 is used, the above-described problems can be solved.

[1-5. Storage of packing box stoppers]
Next, the storage of the packing box stopper 1 will be described below.

  Since the distance D1 between the inner surfaces 2a, 2a of the packing box stopper 1 is approximately twice the maximum thickness D2 of the clamping part 2, the packing box stoppers 1, 1,. By combining them in the opposite direction, a storage method that does not take up space is possible (see FIG. 12A).

  Further, even if the distance D1 between the inner surfaces 2a and 2a of the packing box stopper 1 and the maximum thickness D2 of the clamping portion 2 are substantially the same, the two packing box stoppers 1 and 1 are combined in the opposite direction. By making a set, a storage method that does not take up space is possible (see FIG. 12B).

  If the storage space is not taken into consideration, the distance D1 between the inner surfaces 2a and 2a is not limited by the maximum thickness D2 of the clamping part 2.

[1-6. Summary]
As described above, since the packing box stopper 1 has a structure in which only an object is sandwiched, it can be used as a temporary fixing jig for the flap portion 101 of the packing box 100 or for sealing the packing box 100. It can also be used as a jig.
That is, the packing box stopper 1 is a connecting portion that connects only a pair of sandwiching portions 2 and 2 that are molded into a substantially rectangular parallelepiped shape that is opposed to each other and one end portion in the longitudinal direction of the pair of sandwiching portions 2 and 2. 3. Further, the pair of sandwiching portions 2 and 2 can be elastically deformed in a direction in which they are separated from each other.

  Accordingly, a series of operations of temporarily fixing the flap portion 101 of the packaging box 100 and sealing the packaging box 100 is a simple operation that does not require a complicated operation. The work can be performed efficiently without incurring the deterioration of.

  Further, since the overall shape of the packing box stopper 1 is a simple structure having a substantially U-shape or a substantially U-shape that is bent around a single rectangular parallelepiped, the packing box stopper 1 is It is inexpensive and can have high productivity.

  Further, as described above, the packing box stopper 1 is substantially U-shaped or substantially U-shaped, and the space between the holding portions 2 and 2 is open in the short direction. When the 100 flap portions 101 and the side wall 102 are fitted, the jig can be used as a temporary fixing jig without depending on the size of the packaging box 100.

  Furthermore, the packing box stopper 1 can be used as a temporary fixing jig for the flap portion 101 of the packing box 100 or as a sealing jig for the packing box 100. The stopper 1 is used as a temporary fixing jig for the flap portion 101 of the packing box 100. After the packing box 100 is filled with the contents, the used packing box stopper 1 is removed, and the sealing jig is used as it is. As a result, further improvement in work efficiency can be expected.

  Moreover, since the stopper 1 for packing boxes is sealed in a longitudinal direction, the force which clamps the flap part 101 increases and it can exhibit sufficient sealing function. Therefore, the packaging box 100 can be tightly sealed, and is suitable for delivery, storage or transportation as it is. Furthermore, since it is fitted in the longitudinal direction, it is easier to insert and remove than to fit in the short direction, and the usability is improved.

  In the sealed state, since the flat upper surface of the packing box stopper 1 is exposed, there is no problem in stacking.

  When the packing box stopper 1 is used as a sealing jig, since no gum tape or the like is used, unpacking can be easily performed, and damage and consumption of the packing box 100 can be suppressed. Also suitable for reuse.

  In addition, although it is preferable to provide the taper surface 4a in the front-end | tip part 3 of the clamping part 2 from a viewpoint of the ease of insertion / extraction mentioned above, it does not necessarily need to provide. For example, depending on the thickness of the sandwiching portions 2 and 2 and the degree of elasticity or material of the sandwiching portion 2, there may be a case where smooth temporary fixing or sealing can be performed without providing the tapered surface 4 a.

[1-7. Modified example of packing box stopper]
Each modification of the packing box stopper will be described below (see FIG. 13).

  Although the holding parts 2 and 2 of the packing box stopper 1 shown in FIG. 1 have a substantially rectangular parallelepiped shape, the packing box stopper 1A having the holding parts 2 and 2 whose sides are formed in a curved shape. Or the packing box stopper 1B having the clamping parts 2 and 2 may be used (see FIGS. 13A and 13B).

  In other words, the sandwiching portions 2 and 2 of the packing box stopper 1 may have various shapes as well as a substantially rectangular parallelepiped.

  Further, the packing box stopper 1 shown in FIG. 1 is formed as inner surfaces 2a, 2a whose inner surfaces excluding the tapered surfaces 4a, 4a of the pair of sandwiching portions 2, 2 are parallel to each other. However, it may be a packing box stopper 1C having inner surfaces 2a and 2a each having a wavy curved surface (see FIG. 13C). In this case, the clamping portions 2C and 2C can increase the clamping force.

  Further, it may be a packing box stopper 1D having inner surfaces 2a, 2a that are not parallel to each other (see FIG. 13D).

<2. Second Embodiment>
[2-1. Structure of packing box stopper]
Next, a second embodiment will be described.

The sandwiching unit 7A includes a pair of sandwiching portions 2 and 2A that are arranged to face each other, and a connecting portion 3 that connects only one end portion in the longitudinal direction of the pair of sandwiching portions 2 and 2A.

The clamping part 2 is formed in a substantially rectangular parallelepiped shape, the inner surface is formed as an inner surface 2a, and the outer surface is formed as an outer surface 2b. The sandwiching portion 2A has a wide gap surface 2c and a narrow gap surface 2d as surfaces facing the sandwiching portion 2, and a slope 2e as a surface connecting the wide gap surface 2c and the narrow gap surface 2d ( (See FIG. 2B).
A space sandwiched between the pair of sandwiching portions 2 and 2A is formed as a gap portion 6, and a space sandwiched between the inner surface 2a of the sandwiching portion 2 and the wide gap surface 2c of the sandwiching portion 2A is formed as a wide gap portion 6a. A space sandwiched between the inner surface 2a of the sandwiching portion 2 and the narrow gap surface 2d of the sandwiching portion 2A is formed as a narrow gap portion 6b (see FIG. 2B).
A distance D3 between the inner surface 2a of the sandwiching portion 2 and the wide gap surface 2c of the sandwiching portion 2A is set to a distance approximately twice the thickness of the packaging box 100.
Furthermore, the distance D4 between the inner surface 2a of the sandwiching part 2 and the narrow gap surface 2d of the sandwiching part 2A is substantially the same as the thickness of the packaging box 100.

Therefore, for example, as shown in FIG. 14A, when a single flap 101a is sandwiched, the flap 101a can be inserted to a position where the tip of the flap 101a reaches the vicinity of the connecting portion 3 of the packing box stopper 1A. . That is, the flap 101a is sandwiched between the narrow gap portions 6b.
Further, for example, when two flaps 101a and 101c are sandwiched as shown in FIG. 14B, the flaps 101a and 101c are inserted to a position where the tips of the flaps 101a and 101c reach the vicinity of the inclined surface 2e of the sandwiching portion 2A. Can do. That is, the flaps 101a and 101c are sandwiched by the wide gap 6a.

  The tip portions 4 and 4 of the pair of sandwiching portions 2 and 2A have tapered surfaces 4a and 4a, respectively, which are subjected to taper processing so that the inner surfaces thereof are displaced away from each other toward the tip. The corners of the distal end portion 4 of the sandwiching portion 2 and the distal end portion 4 of the sandwiching portion 2A are formed, for example, as rounded corner portions 4b and 4b that are chamfered in order to improve safety during use.

Since the structure of the packing box stopper 1A is the above-described simple structure, it can be easily formed. For example, the packing box stopper 1A is manufactured by integral molding with a resin.
According to the manufacturing method, the manufacturing cost can be kept low.

[2-2. Usage form as a temporary fixing jig for the flap of the packaging box]
Hereinafter, a method of using the packing box stopper 1A as a temporary fixing jig for the flap portion 101 of the packing box 100 will be described.

As shown in FIG. 3B, the packaging box stopper 1A is fitted from above so as to sandwich both the folded flap 101d and the side wall 102 of the packaging box 100. At this time, the connecting portion 3 of the packing box stopper 1A is elastically deformed so that the pair of sandwiching portions 2 and 2A are displaced in directions away from each other. Further, in order to sandwich both the flap 101d and the side wall 102 of the packaging box 100, the connecting portion 103 of the flap 101d and the side wall 102 of the packaging box 100 is inserted to a position reaching the vicinity of the inclined surface 2e of the clamping unit 2A.
Since the series of operations described above are simple operations that do not require complicated operations, the operations can be performed efficiently without causing a decrease in work efficiency due to the temporary fixing operation.

[2-3. Usage as packing jig sealing tool]
Next, a method of using the packing box stopper 1A as a sealing jig for the packing box 100 will be described (see FIG. 6B).

The tool 1 is inserted from the longitudinal direction of the packaging box 100. At this time, the corners of the flap 101c and the flap 101d are inserted to a position where they reach the vicinity of the connecting portion 3 of the packing box stopper 1A.

Although the case where one packing box stopper 1 is used as a sealing jig has been described, two packing box stoppers 1 and 1 are used, and the packing box stopper is used from both ends in the longitudinal direction of the packing box 100. The tools 1 and 1 may be respectively fitted.
The series of operations described above are simple operations that do not require complicated operations because the packing box stopper 1 is simply inserted from the longitudinal direction of the packaging box 100 after the normal corrugated cardboard flap folding operation. The work can be efficiently performed without causing a decrease in work efficiency due to the stop work.

[2-4. Another form of use as a packaging box sealing jig]
Next, another method for using the packaging box stopper 1A as a sealing jig for the packaging box 100 will be described.
