処理問題をより悪化させる。The above-mentioned "disposable body warmer" and other methods of individually wrapping articles sensitive to oxygen, moisture, corrosive gas, etc., individually one by one, are packaged in a bag. There are many disadvantages as compared with the method described below. (A) If individually wrapped one by one, extra labor and cost are required. (B) Because of the individual packaging, the outer shape of the packaged product is bulky, requiring a lot of storage space, and the transportation cost is also increased. (C) More packaging materials are wasted by individual packaging. (D) The material of the packaging bag is mainly plastic, which wastes valuable petroleum resources. (E) The large amount of discarded plastic bags exacerbates serious waste disposal problems.

使う必要がある。The pressure-sensitive adhesive for forming the peelable pressure-sensitive adhesive 4 is a type of pressure-sensitive adhesive (pressure-sensitive adhesive) widely used in known "pressure-sensitive adhesive tapes" and the like. Among the agents, those having particularly excellent gas impermeability may be selected and used. And, as in the present invention, the adhesive for repeatedly opening and closing the mouth of the bag, it is necessary to use an adhesive that is formulated to have relatively light adhesive strength and excellent hermetic sealing properties. .

ト１，２の必要部分に施すとよい。When the peelable pressure-sensitive adhesive layer 4 is formed, the adhesive force of the pressure-sensitive adhesive, such as obtained by corona discharge treatment, is increased depending on the material of the bag and the type of the pressure-sensitive adhesive. It is preferable to apply a surface treatment agent having a function and a function of enhancing the heat-sealing property of the plastic sheet appropriately to necessary portions of the front and back sheets 1 and 2.

Good. The adhesive-deficient region d may be provided in an appropriate shape and arrangement such as, for example, a narrow band shape and a dot stitch shape. The reason (function) for providing the adhesive-free area d will be described later.

It is formed over the entire width. The mechanical seal portion 5 of this embodiment includes:
Each of the front sheet 1 and the back sheet 2 is provided with a pair of concave grooves 5a and a pair of ridges 5b, which are fitted tightly to each other (see FIGS. 3 and 4).

Note that a knob 6 having a predetermined width is left. Note that the mechanical seal portion 5 may be provided on only one of the two sides of the peelable pressure-sensitive adhesive layer 4. Further, as the mechanical seal portion 5, various known types other than those described above, for example, magic tape (registered trademark), fasteners, various hooks and clips, and the like can be used.

In order to take out the two, the two front and back knobs 6 and 6 provided in the opening 3 are respectively picked with fingers and pulled in a direction away from each other. Then, the ridge 5b is pulled out from the groove 5a, and the sealing state is released.

Be separated. Subsequently, the mechanical seal portion 5 on the lower side of the peelable pressure-sensitive adhesive layer 4 is also released from the sealed state, and the sealed bag A1 becomes
The opening 3 is completely opened.

域を、両方の手の平の間で強く圧迫する等してもよい。Therefore, after taking out only one disposable body warmer, the opening 3 is quickly closed to keep the remaining disposable body warmer from contacting the air as much as possible. To this end, an airtight seal area consisting of a peelable pressure-sensitive adhesive layer 4 and mechanical seal portions 5 and 5 provided on both sides thereof is provided in a sealed bag A1.
From one side end to the other side end, the finger may be pressed "squeezed" with a fingertip. Alternatively, the hermetic seal area may be strongly pressed between both palms, or the like.

In this case, when the hermetic seal area is further pressed, as shown in FIG. 6, the sealed air bubble e which has been strongly pressed escapes to the outside of the hermetic seal area. Is formed.

It may end up being messed up. However, if the pressure-sensitive adhesive-free area d is provided in a part of the area where the peelable pressure-sensitive adhesive layer 4 is formed, the strongly-pressurized air bubbles move toward the nearest pressure-sensitive adhesive-free area d, and the pressure decreases. In this state, the gas is confined in this area, so that the formation of the deaeration path f is prevented.

When the opening 3 is closed after taking out the “single-use warmers”, the peelable pressure-sensitive adhesive layer 4 can be used without paying special attention.
, The sealing bag A1 can be securely sealed. And the mechanical seal parts 5, 5 make this sealing state more reliable.

こり得る。Further, the mechanical seal portion 5 is not limited to a function to make the sealing of the opening 3 more reliable. That is,
If the mechanical seal portion 5 is not provided, if the sealed bag A1 filled with “disposable warmer” receives strong rocking force during transportation or other handling, the “disposable warmer may become peelable. It may occur that the pressure-sensitive adhesive layer 4 is pressed against the edge of the pressure-sensitive adhesive layer 4 with a strong force.

If such peeling occurs in a strange manner, not only will all the disposable warmers in the sealed bag A1 come into contact with the air and be discarded, but also the risk of excessive heat generation will occur. come.

Further, even if any force such as opening the mouth of the bag accidentally acts on the opening 3, the mechanical seal portion 5 on the side close to the opening 3 causes the peelable adhesive layer 4 It almost certainly prevents peeling of the adhesive surface.

The difference from 1 is that the opening 3 is not provided over the entire width of the bag, but is provided obliquely so as to connect the intermediate portions of the upper edge and the side edge on both sides of the corner of the bag. . The opening 3 may be formed by cutting with scissors.

Further, the cost required for forming the peelable pressure-sensitive adhesive layer 4 and the mechanical seal portion 5 can be reduced.

A cover piece 7 for covering and protecting the opening 3 is connected to the edge of the back sheet 2 in the sealing bag A3. A strip-shaped peelable pressure-sensitive adhesive layer 4 is provided over the entire width of the bag on the outer surface of the edge portion of the front sheet 1 except for a knob 8 for opening and closing the bag.
