  By the way, these storage bags 21 are often sealed by degassing or vacuuming in order to ensure the storage stability of the food product 23. Therefore, as shown in FIGS. 6A to 6C, even if one end of the storage bag 21 is cut open, the entire food product 23 cannot be removed smoothly, and some of the food products 23 are stored in the storage bag 21. There is a problem that it remains in the corners of the. This is because a negative pressure portion is formed in the storage bag 21 when the food product 23 comes out.

  Therefore, the consumer scrapes out the food 23 remaining on the corner of the containing bag 21 with chopsticks or a spoon. The operation of scraping out the remaining food products 23 must be performed from the mouth of the storage bag 21 opened by the notch 22, so that it is necessary to return the storage bag 21 upside down many times, which is quite troublesome.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a sealed-type accommodation bag in which the contents can be smoothly taken out in a sealed-type accommodation bag of a type that contains an object to be contained and is deaerated and sealed.

  The sealed type storage bag of the present invention is a sealed type storage bag that stores an object to be stored, is deaerated and sealed, and is a first for forming an outlet for taking out the object from the end of the bag body. And a second slit for forming an air intake port for taking air into the bag body at an end opposite to the end provided with the first slit. Is. A tearing part means the part which gave special processes, such as cutting and perforation, so that a bag may be easily torn by hand. The notch includes not only a notch but also a notch or the like cut into a V shape or a U shape.

  According to the sealed storage bag of the present invention, an air intake port is first formed at the end of the bag body by cutting the second cut portion, and then the container is taken out by cutting the first cut portion. By forming the outlet at the end opposite to the air inlet, when taking out the object to be stored with the outlet down, the end from the end opposite to the end where the outlet is formed enters the inside of the bag body. Air is taken in. Thereby, the part which becomes a negative pressure inside a bag body disappears, and a to-be-contained object falls smoothly from a lower taking-out port.

  A first tearing portion for forming an outlet for taking out an object to be contained is formed at an end of the bag body, and further, an inner portion of the bag body is disposed at an end portion opposite to the end portion having the first tearing portion. The second tearing portion for forming the air intake port for taking in the air is provided, so that when the object to be dropped is taken out with the takeout port formed by the first tearing portion facing down, the second tearing portion is formed. Since air can be taken into the bag body from the air intake port formed by the tearing portion, it becomes possible to smoothly remove the object. As a result, it is possible to take out the objects to be contained in the bag body without any waste, so that resources can be saved.

  In addition, in the case of food items that contain salt such as pickles, if the contained items remain inside the bag, dioxins may be generated during incineration, but the contained items can be removed almost completely. Can suppress the generation of this dioxin and is good for the environment.

  Furthermore, when adding the process of forming the second tearing portion in addition to the first tearing portion provided in the conventional sealed-type accommodation bag, there is almost no facility addition to the production of the accommodation bag, and the production cost of the accommodation bag is almost increased. do not do.

(Embodiment 1)
FIG. 1 is a schematic plan view of a sealed accommodation bag according to the first embodiment of the present invention.

  In FIG. 1, the sealed accommodation bag according to the first embodiment of the present invention is a rectangular bag body 1. The bag body 1 is formed, for example, by stacking films such as nylon and polyethylene, and applying heat to the peripheral edge portion to seal. Further, a V-shaped notch (hereinafter referred to as “notch”) is formed at a longitudinal end portion of the seal portion 2 formed by this seal as a first cutout portion for forming an outlet for taking out an object to be accommodated. 3) is formed.

  Further, an air intake that takes air into the inside of the bag body 1 is the same side as the side where the notch 3 is formed, and an end opposite to the longitudinal direction of the end where the notch 3 is formed. A notch 4a is formed as a second slit for forming the inlet. Further, on the side opposite to the side on which the notch 4a is formed and on the same side as the end on which the notch 4a is formed, air is introduced into the bag body 1 like the notch 4a. A notch 4b is formed as a second slit for forming an air intake port for taking in air.

  (A)-(c) of FIG. 2 has shown the process of taking out the content of the sealing type accommodation bag of FIG. In this sealed type storage bag, pickles 5 as food items are stored as objects to be stored. In addition, the sealed container bag is sealed by degassing and sealing after the pickled product 5 is stored.

  The consumer first forms the air intake ports 6a and 6b shown in FIG. 2A by manually cutting either or both of the notches 4a and 4b of the sealed container. Next, by cutting the notch 3 at the end opposite to the notches 4a and 4b by hand, the contents outlet 7 shown in FIG. 2B is formed at the end opposite to the air inlets 6a and 6b. To do.

  Then, as shown in FIG. 2 (c), the pickled product 5 is taken out with the content outlet 7 of the sealed container bag down. At this time, since air is taken into the inside of the bag body 1 from the air intake ports 6a and 6b on the opposite side to the content outlet port 7, a portion that becomes a negative pressure between the bag body 1 and the pickled pickled product 5 falls. The pickled product 5 falls smoothly from the lower content outlet 7.

  Thereby, since pickles 5 can be taken out almost without remaining in the inside of the bag 1, waste can be eliminated. Moreover, since the pickled product 5 containing salt can be almost taken out, the salt content remaining in the bag body 1 is small, and dioxins generated when the bag body 1 to be discarded is incinerated after the contents are taken out can be suppressed.

  Moreover, since the notches 4a and 4b for forming the air intake ports 6a and 6b can be formed by the same equipment and process as the notch 3, the addition of equipment to the manufacture of such a sealed accommodation bag is not possible. It is almost unnecessary and can be manufactured at low cost.

  In the example of FIG. 1, one notch 4 a and 4 b are provided on the left and right sides of the bag body 1, but only one of them may be provided. Further, in place of the notches 4a and 4b, as shown in FIG. 3, a notch 8 may be formed on the short side of the end where the notch 3 is formed and the end opposite to the longitudinal direction. Further, the notches 4a, 4b and 8 may be formed not only so as to be cut at right angles to the edge of the seal portion 2, but also so as to be cut in an oblique direction.

  In FIG. 4, the sealed container bag according to the second embodiment of the present invention is such that a part of the seal portion 11 of the bag body 10 similar to the first embodiment is a wide seal portion 12. The wide seal portion 12 is provided with a through hole 13 for hanging and displaying mainly at the time of sale. An end portion of the seal portion 11 opposite to the seal portion 12 is provided with a notch 3 similar to that of the first embodiment.

  Further, in the middle of the wide seal portion 12, a lip-shaped cut 14 provided so as to be pulled toward the inside of the bag body 10 is provided. The cut 14 is provided on one surface of the seal portion 12 (the surface in FIG. 4).

  According to such a sealed-type accommodation bag, the bag body 10 is torn by pulling the lip-shaped cut 14 toward the inside of the bag body 10, and the bag body is similar to the notches 4a, 4b, and 8 in the first embodiment. An air intake can be formed for taking air into the interior of 10. Therefore, if the notch 3 on the side opposite to the notch 14 is torn, the pickled product 5 inside thereof can be dropped smoothly and taken out as in the first embodiment.

  Instead of the through hole 13 and the lip-shaped cut 14, a lip-shaped cut 15 may be provided through the front and back surfaces of the seal portion 12 as shown in FIG. By making the cut 15 penetrating in this way, the functions of the through hole 13 and the lip-shaped cut 14 can be provided. This eliminates a through-hole piece (not shown) that is generated when the through-hole 13 is formed, so that it is possible to save the trouble of processing this through-hole piece and reduce the manufacturing cost of the sealed accommodation bag.
