Description

  The present invention uses printed film or transparent film sheet to protect products during transportation, design and visibility during store display, and resource protection and reuse after opening. The present invention relates to a packaging method for a pack and a packaging protection pack.

As a package of a product, a cosmetic box, a whole or partial wrapping with a film sheet, and the like are common. However, a packaging protection pack for protecting a package by wrapping the package with air is known.
As a packaged product and packaging method, a decorative box and a method of packaging the whole with a film sheet are often used. However, a single product of a decorative box and a film sheet does not completely protect the product during transportation. Therefore, it is common to use extra cushioning material such as cardboard or cushioning material separately from the decorative box. When these are displayed as goods after transportation, they become mere garbage, and a large amount of waste is generated.

  Therefore, in order to reduce these wastes, the packaging method of the following patent document 1 and patent document 2 is disclosed. Among these, according to Patent Document 1, an interior body that wraps a package and an exterior body that wraps the interior body with air are disclosed. In this packaging protection pack, a four-layer sheet is formed by bending a cylindrical resin sheet in a belt shape and bending the opening side in the vertical direction with the opening side facing up and down. And after attaching an air valve between the 1st layer and the 2nd layer of a 4 layer sheet, or between the 3rd layer and the 4th layer, it adheres by heat-sealing the upper and lower sides of a 4 layer sheet. In this way, a bag-shaped packaging protection pack having an opening between the second layer and the third layer is formed. In such a package protection pack, the space between the second layer and the third layer is a package storage part. After the package is inserted, air is introduced from the air valve so that the periphery of the storage part is air ( It is covered by the exterior body. In this way, the package is protected by covering the storage portion with air.

  According to Patent Document 2, an exterior body that is formed by folding a rectangular sheet made of a synthetic resin into two layers, and an interior body that is formed by folding a short rectangular sheet having the same width as the exterior body and having a short length. Is sandwiched inside the exterior body. Then, the end portions of the two layers opposite to the bent portion of the interior body are in close contact with the inner surface of the exterior body by heat sealing, and the four layers on the left and right side portions of the exterior body and the interior body are in close contact with each other by heat sealing. A chuck is formed in the opening of the exterior body, and the package is accommodated in the interior body by opening the chuck. After storing the package, air is introduced between the interior body and the exterior body so that the package is protected by the air between the exterior body and the interior body.

Hereinafter, a packaging protection pack according to a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of a packaging protection pack according to the first embodiment of the present invention. The packaging protection pack 51 includes a bag body 1 and a check valve 5.
The bag body 1 is formed by superimposing two sheets of film sheets to be the front surface 1a and back surface 1b (see FIG. 6) of a transparent, translucent or colored resin packaging protection pack 51, and is filled with air. A part 2, a storage part 3 for storing a cosmetic bottle as a package, and a check valve 5 provided with an air supply port 4 for introducing air into the protection part 2 are provided.
The protection part (buffer part) 2 has a substantially rectangular shape, and in this embodiment, a trapezoidal restriction part 6 having an air supply port 4 at the upper end, and ears provided on both right and left sides of the restriction part 6 7 A triangular notch 8 is formed between the restricting portion 6 and the ear portion 7. However, the restriction part 6, the ear part 7, and the notch part 8 may be omitted, and the entire protection part 2 may be rectangular.

On the lower side of the protection part 2, a storage part 3 is formed adjacent to the protection part 2, and the storage part 3 is formed to protrude downward from the lower side 9 a of the protection part 2. In this embodiment, the storage unit 3 has a quadrangular shape having a side 14 and a tip 11, and the size is substantially the same as or slightly larger than the package so that the package stored in the storage unit 3 can enter. It is formed. The length from the base end 10 to the tip 11 of the storage portion is formed to be substantially the same as or smaller than the height of the protection portion 2, and the width of the storage portion 3 is formed to be smaller than the width of the protection portion 2. As for the width of the trapezoidal regulation part 6, the lower part (lower base) is formed to have substantially the same dimension as the width of the storage part 3.
Moreover, although the place where the storage part 3 is formed is formed on the lower side 9a of the protection part 2 in this embodiment, it can be formed on the left and right side parts 9b of the protection part 2. Moreover, although it is preferable to form in the left-right center part of the lower side of the protection part 2, depending on the shape of a package, you may form so that it may shift to either right or left, and the accommodating part 3 is formed in the left-right side part 9b. The same applies to the case.

A supply port 4 is formed in the restriction part 6 of the protection part 2. The supply port 4 is provided with a check valve 5 in which two synthetic resins are overlapped. The check valve 5 has a tube shape, and is disposed in the protection unit 2 from the supply port 4, and the air supplied from the supply port 4 is supplied from the tip 12 to the inside of the protection unit 2 and the protection unit 2. It can supply to the storage part 3 connected to a part.
The bag body 1 is thermally welded 13a to the entire periphery of the protective part 2 and the entire periphery of the storage part 3 in order to maintain the sealing property (note that the width of the weld part is enlarged in the figure for easy understanding). ) The inner surface of the supply port 4 of the check valve 5 is printed, and the printed portion is not thermally welded, so that the supply port 4 is opened. Therefore, the bag body 1 is kept airtight except for the supply port 4 and the check valve 5.
In this embodiment, the check valve 5 is also formed by superposing two sheets of synthetic resin, so that both sides are thermally welded 13b.
When mass-producing such a packaging protection pack 51, a flat film sheet for each unit of the packaging protection pack 51 is sent out continuously or once, and heat, ultrasonic waves, impulses, etc. in the feeding direction at every fixed dimension. Use the one sealed with.

FIG. 2 shows a second embodiment of the present invention.
The packaging protection pack 51 in FIG. 1 is formed by superposing two synthetic resins, but the packaging protection pack 52 in FIG. 2 is an example in which the synthetic resin of a strip-like tube that is cylindrical in the expanded state is superposed. Indicates. Further, in the present embodiment, the length of the ear portion 7 is longer than the restriction portion 6. Except for these points, the present embodiment is the same as the above embodiment.
Thus, when it forms with a cylindrical synthetic resin, welding of the both-sides 9b becomes unnecessary, and the effort of welding can be saved by that much.
In the present embodiment, the check valve 5 is also formed of a belt-like tube, so that welding on both sides is not necessary.
The packaging protection pack 51 shown in FIG. 1 and the packaging protection pack 52 shown in FIG. 2 can be formed by cutting and welding with a continuous sheet of synthetic resin, and can be easily produced because there is no work such as bending.
In addition, one film sheet may be folded back to be two sheets. In this case, it is not necessary to weld one of the side portions 9b of the packaging protection pack 51 shown in FIG.
Further, as in a general plastic bag, a protective part having one side opened and three sides closed may be used, and the housing part 3 may be separately heat-welded to the lower part of the protective part 2.

Next, the packaging procedure in the first and second embodiments of the present invention will be described.
[Packaging procedure 1]
FIG. 3 is a plan view showing a procedure for storing a cosmetic bottle as a package in a packaging protection pack.
The packaging protection pack 51 is held by a holding member (not shown), an air supply nozzle 15 is disposed above the supply port 4, and a package (packaged object) is provided directly below the storage portion 3 of the package protection pack 51. The raising / lowering member 16 which supports is arrange | positioned.
A rod 17 connected to a lifting means (not shown) and a mounting table 18 fixed to the upper end of the rod 17 are fixed to the lifting member 16. A cosmetic bottle 19 as a package is placed on the placing table 18. The shape of the mounting table 18 can be changed in various ways depending on the application. In this embodiment, the mounting table 18 is formed in the same shape as the bottom of the cosmetic bottle 19.

With such a configuration, the nozzle 15 shown in FIG. 3A descends and is inserted into the supply port 4 as shown in FIG. 3B and inserted into the belt-like check valve 5, and then the nozzle The air is supplied to the inside of the bag main body 1 via the check valve 5 by 15, and the air is supplied to the protection part 2 and the storage part 3 communicating with the protection part 2 (gas supply process).
When a certain amount of air is supplied to the bag body 1, the rod 17 of the elevating member 16 rises, and the cosmetic bottle 19 just below the storage unit 3 comes into contact with the tip of the storage unit 3. At this time, the storage unit 3 protrudes downward from the protection unit 2, but when air is supplied to the storage unit 3, the cosmetic bottle 19 pushes the tip of the storage unit 3 with the cap 20 at the upper end of the cosmetic bottle. Thus, it was confirmed that it entered the inside of the storage unit 3. Therefore, the diameter when the storage part 3 becomes cylindrical needs to be larger than the diameter of the body of the cosmetic bottle 19.

As shown in FIG. 4, when the cap 20 of the cosmetic bottle 19 is inserted into the front end 11 of the storage unit 3, the front end 11 folded back by the periphery of the cap 20 of the sheet on the peripheral side of the storage unit 3 having a substantially cylindrical shape. The air a having increased internal pressure enters the folded portion to form an annular groove, so that the sheet forming the storage portion 3 gradually wraps the cosmetic bottle 19.
Accordingly, the storage unit 3 is gradually folded from the distal end side toward the proximal end side by being pushed in by the cap 20 of the cosmetic bottle 19 (see B and C in FIG. 3). As described above, while the cosmetic bottle 19 enters the storage unit 3, the air from the nozzle 15 is weakened or stopped, or the nozzle is stopped while the air is stopped. 15 can be used to vent air. In particular, when the bag body 1 is sufficiently filled with air, it is preferable to release air according to the capacity in which the cosmetic bottle 19 is inserted.

As shown in FIGS. 3B and 3C, when the cosmetic bottle 19 folds the storage portion 3 inward, the portion into which the cosmetic bottle 19 is inserted due to the internal pressure of the bag body 1 is stored on the surface of the cosmetic bottle 19. The air between the surface of the part 3 escapes and the surface of the cosmetic bottle 19 and the surface of the storage part 3 are in close contact with each other. In the drawing, a slight gap is formed so that the boundary between the cosmetic bottle 19 and the storage portion 3 can be seen.
Then, as shown in FIG. 3D, when the cosmetic bottle 19 is entirely inserted into the protective portion 2, the cap 20 portion at the tip of the cosmetic bottle 19 is inserted into the regulating portion 6 ( Packaging process).

Thus, when the cosmetic bottle 19 is introduced into the storage unit 3, if the nozzle 15 is bleeding, the bleeding is stopped, and the nozzle 15 is once again in the bag body 1 (protecting unit 2) a predetermined amount. When air is supplied and the nozzle 15 stops supplying air, if the air filling amount is small, the air is supplied again to the bag body 1 (protection unit 2) to a specified amount. . When a specified amount of air is supplied into the bag body 1, the nozzle 15 is raised and the nozzle 15 is extracted from the check valve 5 (fluid supply stop process).
In addition, although the magnitude | size of the mounting base 18 of the raising / lowering member 16 was made the same as the bottom of the cosmetic bottle 19, the magnitude | size is not ask | required. However, for a large mounting table, the mounting table cannot be inserted into the storage unit, but there is no problem because the package can be inserted up to the lower side 9a of the protection unit 2. Also, if the mounting table is larger than the bottom of the package, place a closing member having an adhesive surface on the surface of the mounting table, and place a cosmetic bottle on it, so that the mounting table is the bottom of the protective part of the bag body There is an advantage in that the storage unit 3 is closed by sticking as it is.

Thus, by storing the cosmetic bottle 19 in close contact with the sheet surface of the storage unit 3, unlike when the cosmetic bottle 19 is viewed with air between the cosmetic bottle 19 and the storage unit 3, Since the transparency is improved, the cosmetic bottle 19 can be clearly seen through the bag body 1. In particular, as shown in FIG. 6, since no sheet is interposed between the protection unit 2 and the storage unit 3, the cosmetic bottle 19 can be clearly seen.
Moreover, the bottom of the protection part 2 which wraps the storage part 3 becomes an annular ellipse, and the self-supporting property of the bag body 1 can be improved. If the package itself is self-supporting, it may be self-supporting by or together with the bottom of the package.

FIG. 7 is a second packaging procedure for the package according to the embodiment of the present invention.
When the dimensional difference between the package and the storage unit 3 is small, or the package has a complicated shape that is difficult to enter the storage unit, the package may not easily enter the storage unit 3. This packaging procedure can easily store the package in the storage unit 3 and can particularly increase the production speed.

[Packaging procedure 2]
FIG. 3 is a plan view showing a procedure for storing a cosmetic bottle as a package in a packaging protection pack.
The packaging protection pack 51 is held by a protection member (not shown), an air supply guide rod 15 a is disposed above the supply port 4, and a package (packaged object) is provided directly below the storage portion 3 of the packaging protection pack 51. ) Is provided. About the raising / lowering member 16, it is the same as what was shown by the packaging procedure 1 of FIG.
In the packaging procedure 2, the guide bar 15a is greatly different from the nozzle 15 in the packaging procedure 1. The guide rod 15a is connected to an air supply unit (not shown) and ejects air from the peripheral surface and is provided with an air vent structure. And the guide part 15b is formed in the front-end | tip part. The guide bar 15 a can be raised and lowered and can be lowered to the tip 11 of the storage portion 3 located at the lower end of the bag body 1.

With such a configuration, the guide bar 15a shown in FIG. 7A is lowered and inserted into the supply port 4, and is inserted into the belt-like check valve 5 as shown in FIG. Is inserted. On the other hand, the elevating member 16 raises the rod 17 and sandwiches the sheet at the tip 11 of the bag body 1 between the tip of the guide bar 15a and the top of the cosmetic bottle 19 (cap 20).
Thereafter, the air is supplied into the bag body 1 by the guide rod 15a, and the air is supplied to the protection part 2 and the storage part 3 communicating with the protection part 2 (gas supply process).
When a certain amount of air is supplied to the bag body 1, the rod 17 of the elevating member 16 is raised. In accordance with this, the guide bar 15a is similarly raised, and the tip 11 of the bag body 1 is raised while being sandwiched between the tip of the guide bar 15a and the cosmetic bottle 19 (cap 20).

As shown in C of FIG. 7, the storage unit 3 is thus folded back gradually from the distal end side toward the proximal end side by being pushed by the cap 20 of the cosmetic bottle 19 (see C in FIG. 7). Thus, the cosmetic bottle 19 can be stored in the storage part 3 in a stable state by sandwiching the tip 11 of the bag body 1 between the guide bar 15a and the cosmetic bottle 19 (cap 20).
About adjustment of air etc., it is the same as the said 1st packaging procedure.
After the cosmetic bottle 19 is stored in the storage unit 3, when a specified amount of air is supplied into the bag body 1, the supply of air is stopped, the guide rod 15 a is raised, and the guide rod 15 a is moved from the check valve 5. Pull out.
By such a packaging procedure, the package can be stored in the storage unit 3 so as to be adapted to the shape of the package as much as possible.

Thus, when the nozzle 15 (or the guide rod 15a) is extracted from the check valve 5, the belt-like check valve 5 becomes flat due to the internal pressure of the bag body 1 and cannot be opened. Does not escape from the check valve 5.
After the storage part 3 is introduced into the protection part 2, the opening generated on the proximal end side of the folded back storage part 3 is closed by a closing member. The blocking member may be completely closed or partially blocked. Thereby, the cosmetic bottle 19 is accommodated in the accommodating part 3 without the accommodating part 3 being pushed back outside by the internal pressure of the bag main body 1 (protection part 2).
Depending on the case, a product description of the package or an instruction manual 21 is required, but as shown in FIG. 3D, it may be stored at the bottom of the storage unit 3 and the storage unit 3 may be closed by the closing unit. Alternatively, the instruction manual 21 may be integrally attached to the closed portion. Of course, it is also possible to attach to an inconspicuous place such as the back of the bag body 1.

The packaging protection pack 51 can thus store the storage unit 3 and the cosmetic bottle 19 inside the protection unit 2. Since the periphery of the storage unit 3 is surrounded by the air in the protection unit 2, and the tip 11 of the storage unit 3 is inserted into the restriction unit 6, which is a recess, by the cap 20 at the upper end of the cosmetic bottle 19. The cosmetic bottle 19 is reliably maintained at the center of the protection part 2. Therefore, the cosmetic bottle 19 can be displayed as it is in the upright position at the time of sale, and the image of the product floating in the air is added by arranging the cosmetic bottle 19 inside the storage unit 3. At the time of transfer, the protection unit 2 acts as an aeration to protect the package such as the cosmetic bottle 19.
It should be noted that the height of the protective part 2 and the length from the base end 10 to the front end 11 of the storage part 3 may be substantially matched so that the upper end of the cosmetic bottle 19 is reliably maintained by the restricting part 6.

As described above, when the cosmetic bottle 19 is stored in the storage unit 3, the air between the surface of the cosmetic bottle 19 and the surface of the storage unit 3 escapes due to the internal pressure of the bag body 1, The surface of the storage unit 3 is in close contact. Therefore, if the container is sealed with a sealing member having a sealing property, the package can be maintained in a substantially sealed state.
If necessary, the packaging protection pack 51 can increase the design and value of the content product with a visual effect by printing a catch copy or the like on the film sheet of the protection unit 2 and / or the storage unit 3. .
Even after the product is taken out by peeling off the closing member etc. at the bottom, even if air is lost, a check valve etc. is provided on the film sheet, so by injecting air again, it can be used as an air cushion, balloon, etc. It can be reused and waste generation can be prevented.
In addition, as shown in the packaging protection pack 52 of FIG. 2, when the length of the ear portion 7 is protruded larger than the length of the restricting portion 6, a large amount of air enters the inside of the ear portion 7, so that the cosmetic bottle 19 This has the effect of improving the buffering property on the cap 20 side. About this, it can apply also to the packaging protection pack 51 shown in FIG. 1, and the packaging protection pack 53 shown in FIG. 8 mentioned later.

FIG. 8 shows a third embodiment of the present invention.
The packaging protection pack 53 of the present embodiment is obtained by folding and storing the storage portion 3 of the packaging protection pack 51 of the first embodiment shown in FIG. 1 in the protection portion 4. A cosmetic bottle can be placed directly through the opening 22 at the end. And after putting a cosmetic bottle, air is supplied from the supply port 4. FIG. And after air is supplied in a packaging protection pack, the opening of the accommodating part 3 is obstruct | occluded with the obstruction | occlusion member.
Such a packaging protection pack 53 may have a configuration in which the storage portion 3 of the packaging protection pack 53 in the first embodiment is folded back and the storage portion 3 is stored in the protection portion 2. The storage unit 3 may be laid out for the purpose of storing the storage unit 3 in the protection unit 2 from the beginning without being folded back. The effect after packaging of the cosmetic bottle 19 after packaging with air or the like in the packaging protection pack 53 is the same as in the first embodiment.

As mentioned above, although this invention was demonstrated in detail, referring an accompanying drawing based on embodiment, the packaging layer packs 51-53 of this invention are not limited to the said embodiment, and deviate from the scope of the present invention. Still other variations or modifications are possible.
For example, in the above embodiment, the check valve 5 in the form of a strip tube is used as the closing member of the supply port 4 of the bag body 1, but the supply port for supplying air instead of the check valve is a plug member (for example, JP You may block | close with the air blowing valve 5 of 2003-182775 gazette).

In the said embodiment, although air was supplied inside the bag main body 1, you may supply another gas instead of air. For example, if the package is light, helium gas can be put inside the package protection pack and floated like a balloon. Further, in the summer season, a liquid (fluid) such as water may be added instead of gas to bring about a cooling effect.
The ears 7 formed on the bag body 1 can be omitted, but the ears 7 may be extended upward and connected to a U-shape or connected to extend the ears 7 as a gripping part.
Moreover, in the said embodiment, although the cosmetic bottle 19 was packaged with the packaging protection packs 51-53 as an example, a package is not limited to the cosmetic bottle 19, and various things can be packaged.
For example, it may be a flat shape or a sphere like an eye drop container.
The shape of the protection part 2 and the storage part 3 is not limited to a rectangular shape, but may be other polygonal shapes. Furthermore, the manufacturing process is complicated, but two synthetic resin sheets are stacked on top of each other. For example, it may be formed into other shapes such as a polished shape and a pyramid shape.
In the above embodiment, the size (volume) of the storage unit is formed larger than the size of the package, but the size of the storage unit may be smaller than the package depending on the strength and elasticity of the synthetic tree sheet. . In this case, the surface of a package and the sheet | seat of a storage part adhere | attach more, and the design property further improves.
