  Embodiments of the present invention will be specifically described below with reference to the drawings. However, the packaging bag of the present invention is not limited to this.

  The packaging bag 1 according to the embodiment shown in FIG. 1 has two plastic films stacked and heat-sealed on the peripheral portion 2.

  The packaging bag 1 is provided with two hook holes (4A, 4B) at a predetermined interval in the substantially triangular wide seal portion 3 in the upper corner area where the seal portion of the peripheral portion 2 intersects. Yes. Accordingly, when the user puts the package into hot water and takes it out after being warmed, the user inserts a stick-like object such as chopsticks into the two hook holes 4A and 4B, and sandwiches the package at two support points. As a result, the package can be reliably lifted from the hot water.

  And since the wide sealing part 3 of the packaging bag 1 is sealed on the whole surface, it has a heat dissipation effect, and after taking out from hot water, it can hold a packaging body with bare hands. Therefore, the wide seal part 3 can be pinched as a holding part, and can be opened by using the notch 5 provided in the seal part of the peripheral part 2 as a trigger.

  In another embodiment shown in FIG. 2, a notch 6 is provided that passes from one hook hole 4 </ b> A to the side edge of the wide seal portion 3. By providing the cut 6 in this way, when the user puts the package into the hot water of the pan, the user can wrap the wide seal portion 3 above the cut in advance by folding the intermediate portion between the hook holes 4A and 4B. Since a gap can be surely provided between the body and the pan, chopsticks and the like can be sufficiently inserted, and the package can be reliably removed from the hot water in the pan. And as above-mentioned, since the corner | angular corner area | region of a packaging bag is sealed on the whole surface, it has a heat dissipation effect, and can take a packaging body with bare hands after taking out from hot water. Therefore, the wide seal portion 3 can be pinched as a holding portion, and can be opened by using the notch 5 'provided in the hooking hole 4A as a trigger.

  In another embodiment shown in FIG. 3, cuts 6A and 6B are provided in the respective hook holes 4A and 4B. By doing in this way, when a user puts a package body in the hot water of a pan, if the intermediate part of both the hook holes 4A and 4B is bent beforehand, the wide seal part 3 above a notch | incision will wrap a package body and a pan. Therefore, the chopsticks and the like can be sufficiently inserted, and the package can be reliably taken out from the hot water in the pan. Furthermore, as shown in FIG. 7, it is also possible to hook on the edge of the pan 8, and since the corners of the packaging bag are not immersed in hot water, the package can be taken out safely.

  In the embodiment shown in FIGS. 2 and 3, the notches 6 and 6A and 6B reach the side edges of the wide seal portion 3 from the hook holes (4A and 4B), but as in the embodiment of FIG. The cuts 6A ′ and 6B ′ may not reach the side edges of the wide seal portion 3. That is, the packaging bag 1 is previously provided with means for providing a notch extending from the hooking hole to the side edge of the wide seal portion 3, and in use, communicates from the hooking hole to the side edge of the wide seal portion 3. It suffices if a notch to be formed is formed. Specifically, as shown in FIG. 4, it is preferable to provide a notch 5 ″ at the side edge of the wide seal on the extension line of the notch 6 </ b> A ′. Further, a notch 5 ′ can also be provided inside the hooking hole 4 </ b> A to provide convenience for opening.

Furthermore, as another means, as shown in the embodiment of FIG. 5, perforations 7A and 7B may be provided in advance at the locations where the cuts are to be made, and the cuts may be formed by cutting the perforations during use. Further, as another means, as shown in the embodiment of FIG. 6, notches 5A ′ ″ and 5B ′ ″ may be provided in advance, and notches may be provided from the notches during use. By doing in this way, it becomes possible to prevent that a film breaks between two hook holes during manufacture of a packaging bag.
Moreover, although each notch and the means for providing the notch shown in FIGS. 2-5 are shown in arc shape, it may be arc shape or linear shape, and can be selected suitably.

In each of the above-described embodiments, the case where two hook holes having a predetermined interval are provided has been described. Two hook holes are sufficient to achieve the object of the present invention, but may be three or more in some cases.
In addition, the shape of the hook holes (circular, square, triangular) and the size thereof or the interval between the hook holes can be appropriately selected depending on the type, size, weight, etc. of the packaging bag. Although the substantially triangular shape has been described as the form, the shape and size of the seal portion at the corner corner can be appropriately selected depending on the type, size, weight, etc. of the package.
In addition, the packaging bag of the present invention is particularly suitable for retort foods, but it is not limited thereto, and it goes without saying that the packaging bag is useful as a packaging bag for other packages requiring heat treatment or chemical treatment.
As the form of the packaging bag, the packaging bag of the present invention has been described based on the packaging bag serving as a four-side seal package. However, the packaging bag of the present invention is not limited to this, and a stand pouch or a gusset bag. Any film can be used as long as it can seal the periphery of the stacked film such as a pillow bag or the like, seal the entire corner, and form two or more hook holes.

As the film used in the packaging bag of the present invention, a single layer film or a laminate film mainly composed of a plastic film can be used, and a known single layer film or a laminate film can be used.
For example, a known laminated film has a structure in which a surface layer, a gas barrier layer, and a sealant layer are laminated in this order. Examples of the material used for the surface layer include a uniaxial or biaxially stretched film such as a polyethylene terephthalate film, a nylon film, and a nylon / ethylene-vinyl alcohol copolymer (EVOH) / nylon co-extruded film. Examples of the material used for the gas barrier layer include a metal foil such as aluminum, a film obtained by vapor-depositing silica or alumina on a base film, and an EVOH film. Furthermore, the material used for the sealant layer is a polyethylene film such as a low density polyethylene film, a linear low density polyethylene film or a high density polyethylene film, or a polypropylene film, an ethylene-propylene random copolymer film or an ethylene-propylene block. A polypropylene film such as a copolymer film may be mentioned.
In addition, in order to hold | maintain a shape when the wide seal | sticker part 3 is bent, the packaging bag which consists of laminated films containing metal foil, such as aluminum, can be used suitably.

The structure of the laminated film can be appropriately selected depending on the type of contents and the like, the heating conditions applied at the time of pressure and heat sterilization, and examples of suitably used laminated films are as follows.
(1) Biaxially stretched polyethylene terephthalate film // biaxially stretched nylon film // aluminum foil // unstretched polypropylene film (sealant layer)
(2) Biaxially stretched polyethylene terephthalate film // aluminum foil // unstretched polypropylene film (sealant layer)
(3) Biaxially stretched polyethylene terephthalate film // EVOH film // Aluminum foil // Unstretched polypropylene film (sealant layer)
(4) Nylon / EVOH / nylon coextruded film // aluminum foil // unstretched polypropylene film (sealant layer)
(5) Biaxially stretched nylon film // polyethylene film (sealant layer)
// indicates an adhesive.
