  A retort pouch 10 according to the first preferred embodiment of the present invention shown in FIG. 1 is a food containing, for example, a pre-cooked curry as a food to form a retort pouch food 11, and the retort pouch food 11 is From the state sold at room temperature, for example, put it in hot water 13 in a pan 12 and heat it for several minutes to several tens of minutes, then take it out from the hot water 13 and open it, and put the stored food on a plate etc. It is. The retort pouch 10 according to the first embodiment allows the heated retort pouch food 11 to be easily and smoothly removed from the hot water 13 using the chopsticks 14 without bringing the fingers directly close to the hot container (pot) 12 or the hot water 13. It was adopted so that it could be taken out.

  The retort pouch 10 according to the first embodiment has a bag body 16 hermetically sealed in a bag body 16 formed by laminating a flexible synthetic resin film 15 and warmed in hot water 13 for use. As shown in FIG. 2, a through hole into which the chopsticks 14 are inserted and locked in a corner region 19 where seal regions 18 a and 18 b formed at least on two sides 17 a and 17 b of the bag body 16 intersect as shown in FIG. 2. In this through hole 20, a slit 21 extending outward from the opening peripheral edge 20 a is cut, and when the chopsticks 14 are inserted and the retort pouch food 11 is lifted, FIG. As shown in FIG. 3, both sides of the slit 21 are bent or bent in some cases, are in surface contact with the chopsticks 14, are deformed so as to follow the chopsticks 14, increase the contact range, In By the end face of the anti-to the through hole 20 to form a flap hits the chopsticks 14, and is easy to hold the locked state to demonstrate the anti-slip effect.

  In the first embodiment, the retort pouch 10 is formed by using a generally used laminated film made of, for example, polyethylene terephthalate / aluminum / polypropylene, as the flexible synthetic resin film 15, and for example, shown in FIG. In this way, the folded portion folded into a planar rectangular shape is used as one side, and the other pieces (the upper side 17a and the side sides 17b on both sides) are sealed and bonded as seal regions 18a and 18b, for example, by heat sealing, and the food is sealed and stored. Formed as a bag. Further, in the seal region 18b of the side edges 17b on both sides, an opening notch 22 is formed at the upper end portion thereof, and the retort pouch 10 can be easily opened from the notch 22 as a starting point. It is like that. Furthermore, in the first embodiment, the corner region 19 where the seal region 18a of the upper side 17a and the seal region 18b of the one side 17b intersect is wide-sealed, and this wide-sealed corner A through hole 20 into which the chopsticks 14 are inserted and locked is formed in the partial area 19.

  And in this 1st Embodiment, the eight slits 21 extended in this through-hole 20 toward the radial direction outer side from the opening peripheral edge 20a are cut in the linear form. When the eight slits 21 extending outward from the opening peripheral edge 20a are cut, when the retort pouch food 11 is lifted by inserting the chopsticks 14 into the through hole 20, as shown in FIG. 3, both side portions sandwiching the slits 21 formed toward the outside of the corner region 19 (particularly formed toward the outside of the diagonal direction X of the retort pouch 10 that is in the gravitational direction). The side portions between which the slit 21 is sandwiched) bends or bends and deforms so as to follow the outer peripheral surface of the chopsticks 14 so that surface contact is possible, or the region sandwiched between the slits 21 is bent and deformed. A biasing force that presses against the outer peripheral surface of the chopsticks 14 is generated as a reaction force of the bending deformation in the bent deformation portion, or the end surface of the through hole 20 is directed in a direction opposite to the removal direction of the chopsticks 14 by the bending deformation. By these, it becomes easy to exhibit a non-slip effect, and it becomes easy to hold | maintain a latching state, and it becomes possible to take out the retort pouch foodstuff 11 heated easily and smoothly from the hot water 13 using the chopsticks 14. FIG. That is, the retort pouch food that is easily and smoothly heated without using the chopsticks 14 and bringing the fingers directly close to the hot container 12 or hot water 13 with a simple configuration in which the slits 21 are provided at the opening peripheral edge 20a of the through hole 20. 11 can be taken out from the hot water 13.

  FIG. 4 illustrates another form of the slit 21 ′ that extends outward from the opening peripheral edge 20 a of the through hole 20 and is cut out in the first embodiment. The slit 21 ′ in FIG. 4 is a sharp wedge shape whose width is gradually narrowed from the opening peripheral edge 20a of the through hole 20 in the corner region 19 toward the outer side in the diagonal direction X of the retort pouch 10 (see FIG. 2). Is formed. Such a slit 21 'also has the same effect as the slit 21 of FIG.

  5 (a) and 5 (b) are corners where the seal region 18a of the upper side 17a and the seal region 18b of one side 17b intersect in the retort pouch 10 ′ according to the preferred second embodiment of the present invention. The through hole 23 formed in the region 19 is shown. In the retort pouch 10 'of the second embodiment, the configuration other than the through hole 23 is the same as that of the first embodiment, and the description thereof is omitted.

  In the second embodiment, a circumferential slit 25 is cut into the peripheral portion 23b of the through hole 23 in a double ring shape with the base end portion 24 continuing to the opening peripheral edge 23a. The circumferential slit 25 enables the peripheral edge portion 23b to protrude. For example, when the retort pouch food 11 is lifted by inserting the chopsticks 14, the peripheral portion 23 b protrudes in a ring shape in the insertion direction Y and is brought into three-dimensional contact so as to follow the outer peripheral surface of the chopsticks 14. 20 and the end surface of the slit 25 and / or the ring-shaped surface formed by the slit 25 can come into contact with the chopsticks 14, exhibiting a non-slip effect and making it easy to maintain the locked state. As a result, the retort pouch food 11 heated easily and smoothly can be taken out from the hot water 13 using the chopsticks 14. Therefore, also in the second embodiment, a simple configuration in which the circumferential slit 25 is provided in the peripheral portion 23b of the through hole 23 without using the chopsticks 14 to bring a finger close to the hot container 12 or hot water 13 directly. The retort pouch food 11 heated easily and smoothly can be taken out from the hot water 13.

  FIG. 6 illustrates another form of the circumferential slit 25 ′ in which the base end portion 24 ′ is connected to the opening peripheral edge 23 a and the peripheral edge portion 23 b protrudes in the second embodiment. The circumferential slit 25 ′ in FIG. 6 is cut in a spiral shape, and when the chopstick 14 is inserted and the retort pouch food 11 is lifted, the peripheral portion 23 b protrudes in the insertion direction Y in a spiral shape. By making it contact three-dimensionally with the outer peripheral surface, the non-slip effect is exhibited and the locked state is easily maintained. Such a circumferential slit 25 ′ also achieves the same effects as the circumferential slit 25 of FIG.

  7 (a) and 7 (b) show corner portions where the seal region 18a of the upper side 17a and the seal region 18b of one side 17b intersect in the retort pouch 10 ″ according to the preferred third embodiment of the present invention. The through hole 26 is formed in the region 19. In the retort pouch 10 ″ of the third embodiment, the configuration other than the through hole 26 is the same as that of the first embodiment, and the description thereof is omitted. To do.
