アスナが設けられている袋口であればシールフア
スナを開けても、シールフアスナは自身の弾性に
よる閉じぐせを持つているために、袋口を扁平な
閉じ状態に保とうとする働きをする。(Problem that the invention aims to solve) Therefore, even if a heat-sealed bag opening is opened, the bag opening tends to remain flat, and if the bag opening is equipped with a seal fastener, the seal fastener cannot be opened. Also, since the seal assuna has its own elastic closing mechanism, it works to keep the bag opening flat and closed.
何れにしても袋口を開けて袋内のものを取出そ

に近い状態に安定してしまい、そのままでは内容
物を取出しにくい。そこで内容物を取出す都度袋
口をいちいち手で開くことになり、面倒である。 In any case, when you open the bag mouth and try to take out the contents of the bag, the bag ends up stable in a flat state or a state close to the flat state where the bag mouth is opened, and it is difficult to take out the contents as it is. Therefore, each time the contents are removed, the bag opening must be opened by hand, which is cumbersome.
また袋内に内容物を容れる場合も、その都度袋
口を手で開いてその状態を保つておく必要がある
のでやはり面倒である。 Moreover, when putting the contents into the bag, it is necessary to open the bag opening by hand each time and keep it in that state, which is also troublesome.

密閉に支障を与えることはない。(Function) Even if the flat bag mouth is opened from the sealed state by heat sealing or seal fasteners, it tries to maintain its flat state or a state close to it as before. On the other hand, the folded pieces provided at both ends of the bag mouth are kept in a state in which the front and back members are closed or in a close state by the closure of the elastic member attached thereto. Therefore, the flap piece and the elastic member attached thereto help but do not prevent the bag opening from becoming flat, and do not interfere with the sealing of the flat bag opening by heat sealing or seal fasteners. do not have.

ることができる。 Furthermore, since the folding pieces at both ends of the bag opening are formed independently, the bag can be easily folded back to the outside of the bag opening while pushing open the front and back parts against the closing tendency of the elastic member. At this time, the inner and outer surfaces of the elastic member are inverted together with the folded piece, and the elastic member is opened wide by 180° or more. For this reason, the elastic member tries to return to its original closed state with the folded piece, but the elastic member is held back by the bag opening through the folded piece, with the front and back sides of the end of the bag opened as far as possible, and the bag becomes stable. The mouth is held open to the extent that the front and back sides of its ends are pulled apart. The degree of opening of the bag opening at this time can be appropriately set by the length and restoring force of the elastic member.
この状態は折返し片を弾性部材と共に手で折返
し前の状態に戻すことにより解かれる。 This state can be resolved by manually returning the folded piece together with the elastic member to the state before folding.
(実施例)
第1図から第5図に示す本考案の調理物の保存
や再生に便利な袋とした場合を示す第1の実施例
について説明する。(Example) A first example will be described in which a bag according to the present invention shown in FIGS. 1 to 5 is convenient for storing and recycling cooked food.
第2図に示すように表裏が平面部1a,1bと

ことができる。 The bag portion 1 is formed by sealing and welding parts of a sheet material that is corrosion-resistant, heat-resistant, cold-resistant, and poses no food hygiene problem. 4 is the sticker fee. Also, when considering food processing using a microwave oven, microwave ovens that use metal foil that causes electrical discharge should be avoided. As such a sheet material, a single suitable resin film such as polyester, polyethylene, polyamide, etc., or a laminate of a plurality of resin films may be used.
For example, the sheet material 3 is horizontally long, and sealing fasteners 2a and 2b are attached to both ends of the same surface so as to cross it.
By integrally molding, heat welding, high frequency or ultrasonic welding, lifting both ends slightly and bringing them together at the center as shown in Figure 5,
The basic shape of the bag portion 1 and the bag opening 1c extending perpendicularly from one plane portion 1a of the bag portion 1 as shown in FIG. 2 can be formed.
そこで第5図におけるシート材3の互いに向き

溶着することで、第2図に示す多目的袋が得られ
る。 Therefore, the multi-purpose bag shown in FIG. 2 is obtained by heat-sealing or seal-welding the sealing margins 4 of the opposing edges of the sheet material 3 in FIG. 5 as shown by the arrows, or using high frequency or ultrasonic waves.
袋口1cの部分については、袋口1cの部分を
倒して平面部1aとの間に離型紙を挟み込んだ状
態で、工具を当ててシール溶着すれば、他の部分

場合シール代4のシール溶着はいわゆる横シール
のみとなる。 Of course, it is possible to select as appropriate what kind of material and what method and procedure to use for manufacturing. For example, instead of using release paper, if you use a laminate of a film with a low melting temperature on the inner surface and a film with a high melting temperature on the outer surface, the inner surfaces will be easily welded together.
The outer surface is not welded. In this case, the sealing material 3 is continuously flowed in the direction of the arrow in FIG. 5 while the continuous sealing fasteners 2a and 2b are welded to the required locations, and then the sheet material 3 is formed into a predetermined cross-sectional shape using a former. It is convenient to use an automatic method of sealing at an appropriate position. In this case, the seal welding of the seal allowance 4 is only a so-called horizontal seal.

態に一体成形、熱溶着あるいは高周波ないし超音
波溶着しておくことにより行つている。 At both ends of the mouth rim 1d of the bag mouth 1c, independent folding pieces 1 are formed by notches 1i provided in the center of the mouth rim 1d outside the seal fasteners 2a and 2b.
e, 1e are formed. Each folded piece 1e, 1e
An elastic strip 5 made of synthetic resin whose elastic force is several times higher than that of the seal fasteners 2a and 2b is attached to the inner surface of the seal fasteners 2a and 2b (Fig. 3). This necessary elastic force can be appropriately set depending on the material, cross-sectional area, cross-sectional shape, etc. Also, the garnish is Sealfu Asuna 2
Similar to a and 2b, this is achieved by continuous integral molding, thermal welding, or high frequency or ultrasonic welding on appropriate portions of the sheet material 3.

るが弾性条体5の方が数倍高い。 Therefore, the elastic strip 5 has each folded piece 1e, 1e.
The front and back parts of the folded pieces 1e and 1e are welded to each other at the sealing margin 4 at the end of the bag opening 1c and integrated as shown in FIG. It is given a closing habit that brings it into a closed state or close to it. This closing tendency also occurs in the seal fasteners 2a and 2b, but it is several times higher in the elastic strip 5.
また袋口1cの端部のシール代4の部分には、
折返し片1eの基部の少し下に切込み6を入れ、
折返し片1eを外側に折返すのにシール代4の部
分が邪魔にならないようにしている。 Also, in the sealing allowance 4 at the end of the bag opening 1c,
Make a cut 6 slightly below the base of the folded piece 1e,
The sealing allowance 4 is kept out of the way when folding the folding piece 1e outward.

定する。 When the bag part 1 is placed lying down, for example, on one plane part 1b, it is naturally stable in that state. A bag opening 1c extends from the center of the upwardly facing flat surface 1a. Therefore, as shown in the figure, the bag opening 1c can be opened upward by disengaging the seal fasteners 2a, 2b of the bag opening 1c. This open state is achieved by folding the folded pieces 1e, 1e toward the outside of the bag opening 1c as shown in FIG.
The elastic strip 5 is forcibly pushed open by more than 180 degrees and turned upside down together with the folded piece 1e.
As shown by the arrow in the figure, the folded piece 1e tries to return to the original closed state with the folded piece 1e, and overcomes the tendency to close the front and back sides of both ends of the bag opening 1c by the seal fasteners 2a and 2b, and returns the folded piece 1e to the state shown in Fig. 1. The bag is pulled apart through the bag opening 1c and stabilized by balancing the pulling force of the bag opening 1c. Therefore, the bag opening 1c is maintained in the open state shown in FIG. 1 even in the released state when the user's hand is removed, and the overall bulge of the bag opening 1c thereby stabilizes the bag in the upright position.
これにより袋口1cには手を添えたりしなくて
も保存したい食品を片手で流し込むことができ

よつて食品の流し込み終了時にシールフアスナ2
a,2bを閉じて密封する作業も楽に行える。 Thereby, the food to be stored can be poured into the bag opening 1c with one hand without having to touch the bag opening 1c with the user's hand. It is effective to place the other hand, which is usually free, on the bag opening 1c. Also, due to the self-supporting nature of the bag opening 1c, the seal fastener 2 is closed when the food is poured.
The work of closing and sealing a and 2b can be done easily.
したがつて食品の充填および密封を行うのに、
従来袋自体をその口部が上に向いて開口するよう
に食品の充填開始から密封完了まで終始持ち上げ
続けなければならないのに比べ作業が大幅に簡略
化する。 Therefore, when filling and sealing food,
This greatly simplifies the work compared to the conventional method in which the bag itself had to be lifted with its mouth facing upwards from beginning to end until the bag was completely sealed.

保たれており、内容物が流出するようなことを防
止することができる。 The food thus hermetically housed can be stored as is, such as by freezing. At this time, it is advantageous to stack the bag portions 1 in a lying state for efficient use of storage space and organization. In such a stacked state, the inner pressure of the bag portion 1 increases as the lower portion receives the weight of the upper portion until the food solidifies into a frozen state. However, the bag opening 1c of the lower bag is sandwiched between the bag opening 1c of the upper bag and receives heavy pressure due to stacking, and even if the internal pressure rises, it will not be pushed open. Therefore, the seal fasteners 2a and 2b are firmly maintained in a sealed state by engagement, and it is possible to prevent the contents from flowing out.
保存中の食品を再生処理するのに、袋部1は第
1図のように平面部1bにて横たわり、袋口1c

に移す手間やその器を汚してしまうと云つたこと
が解消される。 To recycle stored food, the bag part 1 lies on the flat part 1b as shown in Figure 1, and the bag opening 1c
There is no need to worry about the contents leaking out by handling the seal fasteners 2a and 2 with them open upward.
By simply disengaging b and placing it in the microwave in the state shown in Figure 1, frozen food can be regenerated along with the packaged bag 1 without the contents leaking out or the bag 1 bursting. This eliminates the trouble of transferring to another container and contaminating the container.
再生処理が終ると内容物は流動性のものになつ
ているし、袋部1をその袋口1c部を境にそれと

連続して安定しやすいのいで、移し容れがさらに
容易になる。 Once the recycling process is complete, the contents will be fluid, and the bag 1 can be folded in half in the direction of the arrow in Figure 1 on the opposite side of the bag opening 1c. Hold the bag with the bag opening 1c facing down, and the bag opening 1
Since c communicates with both folded parts of the bag part 1 over its entire width, the entire content inside the bag part 1 flows out smoothly and is easily transferred to each container actually used. be able to. Moreover, since the bag opening 1c is continuous with both of the folded parts of the bag part 1 and is easy to stabilize, the bag can be transferred even more easily.

気を逃すいわば安全弁の役目を果たすようにする
ことができる。 Of course, if the bag opening 1c is left open from the beginning during regeneration in a microwave oven, too much moisture will escape, so it is preferable to open the bag opening 1c at a suitable time during reproduction.
Therefore, the seal fasteners 2a and 2b are designed to strongly resist the push-opening action from inside due to the internal pressure of the bag. It is a good idea to hold something, such as a strip of film, of an appropriate width and at an appropriate position. In other words, the engagement of the seal fasteners 2a and 2b inside the part where they are engaged is loose, so when the internal pressure rises to the maximum limit during regeneration, the engagement of that part is automatically disengaged and the steam is released. It can be made to act as a safety valve.
