[Structure] A buffer bag with a tongue, characterized in that an adhesive tape is attached to the inner surface of the opening of the bag of the air bubble sheet.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag that can be reused by repeatedly opening it with a cushioning material and is also effective for partial packaging of large items to be packaged.

[0003]

[Prior art]

 (1) Conventionally, when a bubble sheet made up of two or three or more films having a large number of independent air chambers is used as a bag, the opening is generally sealed with a polyolefin or paper. Tapes coated with an adhesive have been used for such materials.

(2) However, in the case of using a tape coated with these adhesives, if the adhesive force of the adhesives is not sufficient, the opening cannot be sealed sufficiently, and the adhesives When the adhesive strength of the product was sufficient, the bag of the foam sheet, which is the base material, was often torn or damaged due to its strong adhesive force when opening. Therefore, the air bubble sheet bag used for such a sealed application was used only once and was rarely reused.

(3) In order to solve these problems, there is a method of attaching a magic tape or laminating a plastic chuck to the inside of the opening of the bag, but it is a base material. There was another problem that the price of the material and the labor cost were too expensive compared to the strength of the bubble sheet bag and the frequency of reuse.

[0006]

[Problems to be solved by the device]

 Therefore, as a result of examining these conventional techniques, the inventors were able to summarize the following three problems. (1) The adhesive strength of the adhesive of the tape used for sealing the bag of the air bubble sheet as the base material must be strong enough to maintain the sealed state and weak enough to be easily peeled off. It is also preferable that there is no adhesive residue when peeled off. (2) The tape used to seal the bag of the air bubble sheet, which is the base material, must be relatively inexpensive. It is preferable that they are equivalent to the tapes used conventionally. (3) Considering post-treatment after use, the material of the tape is preferably the same as that of the bag of the air bubble sheet as the base material. Since the main material of these foam sheets is polyolefin, it is preferable that the material of the tape is also the same polyolefin as the foam sheet.

[Means to be solved]

 FIG. 1 shows one embodiment of the buffer bag of the present invention. 1 shows a cushioning bag made of an air bubble sheet as a base material, and 2 shows a laminated tape according to the present invention. This tape is made of a polyolefin material and has an adhesive applied on one side. The adhesive-free surface of this tape is laminated on the cellular sheet that is the base material.

Polyethylene tape is generally used as a material for the air bubble sheet, and therefore a polyethylene tape (hereinafter referred to as an adhesive tape), for example, Nitto Denko, “SPV” or San-A Chemical Co., Ltd., "Sanitecto" is good.

[0010]

[Fig. 2]

An example using these adhesive tapes as the present invention will be shown below. FIG. 2 shows a cross-sectional view of one embodiment of the cushioning bag of the present invention having the same structure as that of FIG. 1, where 1 is a bubble sheet generally labeled with a product name such as “air bag”. It is a buffer bag made by. The bubble sheet shown in FIG. 2 is a so-called “three-layer product”, which is a flat film (hereinafter referred to as a back film) 3, a film having convex portions attached to a back film (hereinafter referred to as a cap film) 4 Further, it is composed of a flat film (hereinafter referred to as a liner film) 5 attached to the top of the cap film. Inside the opening of this bag, on the back film 3, two adhesive tapes are laminated so that the adhesive-free surface is on the base material.

With the adhesive tape 2 laminated on the opening, this buffer bag can seal the bag by inserting the object to be packaged into the bag and then sticking the opening from the outside. Since the adhesive tape is laminated, it is not necessary to seal the opening with separate tapes because the insides of the openings are stuck together due to the adhesive applied to the adhesive tape 2. Furthermore, the adhesive applied to the adhesive tape 2 has sufficient adhesive strength to keep the bag in a sealed state, and also has excellent peelability, so that it can be easily opened. It does not damage the bag of foam sheet, which is the base material. Moreover, the adhesive agent applied to the adhesive tape 2 is not so markedly reduced in adhesive strength even after repeated sticking and peeling, so that it can withstand repeated opening and sealing and repeated use.

[Figure 4]

FIG. 3 and FIG. 4 show sectional views of the second and third embodiments, respectively. As shown in FIG. 3, the air bubble sheet as the base material may be a so-called two-layer product composed of two films, a back film 3 and a cap film 4. However, in this case, it is desirable to laminate the adhesive tape on the back film 3 or the film on the flat side of the bubble sheet, as shown in the figure. As the bubble sheet, in addition to the above-mentioned one, a sheet having double air chambers as shown in FIG. 4 may be used.

[Figure 8]

Further, as shown in FIG. 5, an adhesive tape may be laminated on the side of the liner film 5 of the three-layer product. In this case, the structure of the buffer bag itself is the reverse of the example of FIG. Further, in FIGS. 2 to 5 above, the adhesive tape was laminated only on one side inside the opening, but when higher sealing of the bag is desired, as shown in FIG. Alternatively, an adhesive tape may be laminated. This aspect is particularly effective in the case of "partially wrapping the projecting portion of a long or large article to be packaged" described later.

In addition to this, as shown in FIG. 7, an adhesive tape may be laminated on the outside of the bag in addition to the inside of the opening. With the buffer bag having such a configuration, it is easy to put the contents in the bag, and after sealing the bag, attach a label or a slip that clearly indicates the contents to the outside of the bag.

FIG. 11

As described above, the cushioning bag of the present invention is remarkably improved in workability and cost as compared with the cushioning bag of the prior art even when the contents are put in the cushioning bag and used in a sealed manner. However, it is also effective when partially projecting the protrusion of a long or large package. This will be described below with reference to FIGS. 9, 10, and 11.

FIG. 9 and FIG. 10 show an example in which the conventional cushion bag and the cushion bag of the present invention are used as a head cover of a golf club. In the buffer bag 6 of the prior art shown in FIG. 9, after covering the head, the opening of the head must be bound separately by using a tape 7 separately. In this case, if the tape is removed, the buffer bag will be damaged at that time and cannot be reused. Also, if it is tied with a string instead of tape, it may be possible to reuse it, but the workability will be extremely reduced.

However, if the cushioning bag 1 of the present invention is used as shown in FIG. 10, by covering the head part and then pressing the adhesive tape 2 laminated in the opening to the base part of the head, it is brought into close contact. The work is complete. In addition, there is no concern about adhesive residue on the head, and repeated reuse is possible.

FIG. 11 shows an example in which a bicycle is partially packaged using the cushioning bag of the present invention. Also in this case, similarly to the head of the golf club of FIG. 10, the protrusions of the handlebar, saddle, pedal, etc. are covered with the buffer bag of the present invention, and the tape 2 having the adhesive, which is laminated on the opening, is pressed. The work is completed by bringing them into close contact with each other. In addition, the fact that there is no adhesive residue and repeated reuse is the same as in the case of the golf club head of FIG.

[0023]

[Action]

 By laminating a tape made of a polyolefin-based material on the bag 1, which is also made of a polyolefin-based material, with a tape coated with an adhesive agent, the workability in packaging the object to be packaged is improved, and reopening and reopening are performed. It can be used repeatedly in a sealed manner. In addition, even in the case of partially packaging the protruding portion of a long or large packaged object, the workability can be significantly improved and the cost can be reduced by reuse.

[0024]

[Effect of device]

 The invention of the present application has the following advantages over the conventional air bubble sheet bag. (1) It is excellent in workability because it does not require a separate tape for airtightness unlike the conventional air bubble sheet bag. (2) The bag can be reused because the bag is not damaged during the opening operation unlike the conventional bubble-sheet bag. (3) Since the laminated adhesive tape uses the same polyolefin material as the bag, it can be recycled and recycled. (4) When partially packaging a long or large projecting portion of an article to be packaged, the workability is superior to that when a conventional buffer bag is used. (5) In the case of (4) above, since it can be used repeatedly, it is excellent in cost. (6) Since the laminated adhesive tape has excellent removability, it can be repeatedly opened and closed, and is a cheaper alternative to the zipper bag with a cushioning function.

[Correction content]

With the adhesive tape 2 laminated on the opening, this buffer bag can seal the bag by inserting the object to be packaged into the bag and then sticking the opening from the outside. Since the adhesive tape is applied to the adhesive tape 2, the insides of the openings are bonded to each other, and it is not necessary to seal the openings with tapes prepared separately. Furthermore, the adhesive applied to the adhesive tape 2 has sufficient adhesive strength to keep the bag in a sealed state, and also has excellent peelability, so that it can be used as a base when opening. It does not damage the air bubble sheet as a material. In addition, since the pressure-sensitive adhesive applied to the pressure-sensitive adhesive tape 2 is not significantly reduced in its adhesive force even after repeated bonding and peeling, it can withstand repeated repeated opening and closing. In addition, the notches can be provided in the seal portions on both sides of the opening portion of the bag to make the opening easier.
