DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 4 show a first embodiment of the present invention. According to this, the buffer packaging bag for sending goods according to the present invention is roughly divided into a packaging bag main body 1, an air introduction pipe 2, a check valve 3, and a cover piece 4 for inserting and removing an article. It is configured.

The packaging bag body 1 communicates between the outer bag 5 and the inner bag 6 made of an airtight plastic film only through the communicating portion 8 on the bottom 7 side of the two bags 5 and 6. The air filling and enclosing portion 9 formed to be bent so as to face each other, and the inner bag 6 forms an article storage portion 11 having an insertion / removal opening 10 on the opposite bottom side, and the air is filled with the air. The filling / sealing portion 9 is linearly adhered at substantially equal intervals at a plurality of locations between the adhesive seal portions A on both side edges, over the bottom portion 7 and the insertion / removal opening 10, and the adhesive seal portions B Each bottom 7a
In this embodiment, eight independent air charging / sealing compartments 9a are formed so as to be opposed to each other by being bent so as to communicate with each other only through the communicating portions 8a on the sides. In the figures, c and d indicate adhesive seal portions in which the outer bag 5 and the inner bag 6 are adhered to both sides of the insertion / removal opening 10. In addition, the above-mentioned compartments 9a for filling and enclosing each air have different lengths on the front side and the back side of the packaging bag main body 1,
At the upper edge of the back side of the air filling / enclosing compartment 9a, it is formed to be slightly shorter than the air filling / enclosing compartment 9a on the front side because of the connection of the air introduction pipe 2 described below. ing.

Next, the air introduction pipe 2 is formed by extending the peripheral edge of the back side of the insertion / removal opening 10 of the packaging bag body 1 by a required length and integrally connected. 12 is formed flat and narrow by a double airtight plastic film provided with a narrow channel 13 formed by bonding and sealing the other two sides to the other side. In order not to adhere to the packaging bag body 1 at the end edge on the side of the introduction port 12, a loose piece 14 separated from the packaging bag body 1 is formed, and to clearly indicate the position of the air introduction port 12, A narrow tape 15 is inserted into the flow path 13, and its end protrudes from the air inlet 12.

The check valve 3 is a well-known plastic flat valve.
As described in Japanese Patent Publication No. 35019, the apparatus is composed of an air flow pipe formed flat by a plastic film, and a valve main body installed in the flow pipe. A two-folded flat plastic film piece having a closed portion at the distal end and an open portion at the proximal end, and both side edges of the valve body are bonded to both side edges of the flow pipe, respectively. Thus, air can be circulated through gaps formed between both inner surfaces of the flow pipe and both outer surfaces of the valve body (detailed illustration is omitted).

As shown in FIGS. 1, 2, and 3, the plurality of check valves 3 configured as described above are
At the inner edge of the insertion / removal opening 10 of the article storage unit 11 in the above, each compartment 9a is connected to a non-adhesion portion at a connection portion (adhesion seal portion c) between each air filling / sealing compartment 9a and the introduction pipe 2. Each check valve 3 is installed in each of the compartments 9a by inserting the non-adhered portions into the contact portions between the inner surfaces and the outer surface of each check valve 3. Thus, each compartment 9a is connected to the introduction pipe 2 only through the flow path of each check valve 3.
In this way, a plurality of air filling / sealing compartments 8a are connected to one side edge of the introduction pipe 2 in a parallel state so that they can communicate with each other only through the flow path of the check valve 3.

Next, the closing piece 4 of the insertion / removal opening 10 of the article.
Is integrally and slightly extended over the entire width of the outer edge of the insertion / removal opening 10 and a narrow adhesive layer 16 is provided over the entire upper portion of the inner surface thereof. Release paper 17 is adhered to the adhesive layer 16.

The entire outer surface of the packaging bag main body 1 and the cover piece 4 in the buffering packaging bag for sending goods constituted as described above.
A writable tough paper 18 such as kraft paper is layered on the outer surface of the wrapper to facilitate the description of the sender's address and the address of the recipient and to prevent the packaging bag from being damaged. I have.
It should be noted that the so-called “layer arrangement” is a general term for the respective superimposed forms such as lamination, sticking, covering, and fitting.

Next, the operating state of the first embodiment of the present invention configured as described above will be described together with its operation and effects.
First, the buffer-required article A is accommodated in the storage section 11 from the article insertion / removal opening 10 of the packaging bag main body 1, and then the loose piece 14 on the introduction port 12 side of the air introduction pipe 2 is picked up with a fingertip. When an air supply nozzle (not shown) can be easily inserted into the introduction port 12 and air is supplied and press-fitted into the flow path 13 after the insertion,
The air is rapidly introduced into the compartments 9a through the flow passages of the check valves 3 sequentially from the air filling and filling compartments 9a connected to the innermost portion on the closed side through the narrow introduction pipe 2. Is done.

The air introduced into each of the compartments 9a is introduced and filled into the opposite sides thereof through a communicating portion 8a provided on the bottom 7a side thereof, and swells the compartments 9a.
Thereby, the buffer required article A is softly and elastically held from the outside. Next, the release paper 17 provided on the cover piece 4 is peeled off, and the cover piece 4 is bent toward the insertion opening 10 side, and is adhered to the outer surface of the main body 1 using the adhesive layer 16, and The packaging of the buffer-required article A is completed by closing the opening 10.
Since the air introduction pipe 2 provided on the periphery of the opening is not filled with air, the cover piece 4 can be easily and reliably adhered.

The stored article A packaged as described above
Is securely buffered from the outside by the filling and filling compartments 9a inflated with air, so that it does not perturb inside the packaging bag, is sufficiently protected from external impacts, and is broken. There is no fear, and since each of the compartments 9a is configured to independently fill the air, even if one compartment 9a breaks and releases the enclosed air,
The buffer action can be maintained by the other expanded compartments 9a.

Further, since the insertion / removal opening 10 is closed, it is possible to reliably prevent the accommodated article A from escaping during handling such as transportation, and to use a kraft paper layered on the outer surface of the packaging bag. By using the writable tough paper 17, the strength as a packaging bag can be remarkably improved, and the address and name of the sender and the recipient can be clearly specified.

Next, FIG. 5 to FIG. 7 show a second embodiment of the present invention. This embodiment has all the components of the first embodiment of the present invention. I have. That is, the configurations of the packaging bag main body 1, the air introduction pipe 2, the check valve 3, and the cover 4 for inserting and removing the article are completely the same as those of the first embodiment of the present invention, and are different therefrom. The reason is that the slightly thicker kraft having the colored printing layer 19a provided on the back surface of the packaging bag main body 1 is provided in the vicinity of the slightly lower side of the insertion opening 10 in the first embodiment. This is a point where a wide tape-shaped paper material 19 having delamination property made of paper is adhered in the lateral direction, and when the cover piece 4 is bent to cover the insertion opening 10,
The second embodiment differs from the first embodiment in that the narrow adhesive layer 16 provided on the inner surface of the cover piece 4 is configured to adhere to a substantially intermediate position on the surface of the paper 19. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals.

Therefore, according to the second embodiment, the operation brought about by the first embodiment,
All the effects can be achieved, and the following unique functions and effects can be achieved. That is, according to the second embodiment, when the packaging bag main body 1 in which the articles are stored and the insertion / removal opening 10 is covered by the cover piece 4 is peeled off and the cover piece 4 is peeled off, the figure is opened. As shown in FIG. 7, the colored printed layer 19a on the surface layer of the paper material 19 having delamination property is peeled and transferred to the cover piece 4 side by the adhesive force of the adhesive layer 16 of the cover piece 4, and the paper Since the peeling trace 19b is formed on the material 19 and the re-adhesive force of the adhesive layer is lost, it is possible to effectively remove the stored article A due to malicious or mischievous acts during the transfer of the packaging bag storing the article A. An advantage that can be prevented or suppressed is added. In the second embodiment, "paper material having delamination property" refers to, for example, when an adhesive tape, an adhesive tape, or the like is adhered to the surface of the paper material, and the tape is peeled off. A paper material having the property that the surface layer of the paper material is peeled off and transferred to the tape side.

The main embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments, but can achieve the object of the invention and do not depart from the gist of the invention. It goes without saying that various design changes are possible.

[0021]

According to the buffering bag for sending goods of the present invention described in the first aspect, the following excellent effects can be achieved.

(1) Since the flow path of the air introduction pipe is formed narrower than that of the above-described conventional one, the introduction of air into the compartment for filling and enclosing a plurality of respective airs is remarkable. It can be carried out quickly and efficiently, and the air introduction pipe provided on the back edge of the insertion / removal opening of the article is not swelled with air in a wavy manner. Can be easily and surely adhered to the cover piece for covering the cover.

(2) Since the edge of the air introduction pipe on the side of the air introduction port is released without being adhered to the packaging bag main body, the air supply nozzle is opened by picking up the released piece with a fingertip. Can be easily inserted into the air inlet.

(3) Since the accommodated articles are securely held in a buffered manner from the outside by the inflatable compartments, they do not move inside the packaging bag, are sufficiently protected from external impacts, and are broken. There is no danger.

(4) Since each of the compartments is independently filled with air, it is possible to control the excessive swelling of the entire packaging bag, and one compartment is broken to release the enclosed air. However, the buffer action can be sufficiently maintained by the other swelling compartments.

According to the cushioning packaging bag for sending goods of the present invention described in claim 3, the above (1), (3),
The following effect can be achieved in addition to the effect of (4).

[0027] A paper material having delamination property, such as kraft paper, is attached to the back surface of the packaging bag body near the insertion / removal opening of the article provided in the packaging bag body, via an adhesive layer. When the packaging bag body containing the articles and covering the insertion / removal opening with the cover piece is peeled off and opened, the surface layer of the paper material having delamination properties is covered. Because the adhesive force of the adhesive layer of the closing piece peels and transfers to the covering piece side to form a peeling mark on the paper material and to lose the adhesive force of the adhesive layer, the transfer of the packaging bag containing the articles is performed. Among them, there is a great advantage that it is possible to effectively prevent or deter the removal of stored articles due to malice or mischief.
