Description

  The present invention relates to a pouch sleeve, and in particular, includes a sleeve made of cardboard or the like formed in a cylindrical shape and a pouch made of a film attached to the inside of the exterior body, and the pouch can be carried independently and by the sleeve. The present invention relates to a technique suitable for use in a pouch sleeve that can be three-dimensionalized and filled with food that can be cooked by pouring hot water.

  Conventionally, a plastic film bag has been applied to contain foods to be cooked by pouring hot water. A typical example of a plastic film bag for containing such pouring food is a laminated film bag called a so-called “pouch”. In addition to this, as a container for pouring hot water into a container and heating it, a molded container made of expanded polystyrene, a double container made of a paper cup, or the like is widely used. In addition, as packaging containers for cooking dishes containing ingredients etc. in a microwave oven, mainly heat-resistant molded containers and double containers with a heat insulating effect added to the peripheral wall on the molded containers are marketed. Has been.

  The packaging body of Patent Document 1 is heated in a range with the pouch placed in the packaging body, and the pouch taken out together with the packaging body from the microwave oven is left as it is, that is, surrounded by the packaging body. Can be provided and a method of eating processed food in the pouch can be provided. In this new eating method, the package is a tool for maintaining the pouch in a self-supporting state in the microwave oven and functions as tableware together with the pouch when eating.

  The pouch sleeve 10 of the present embodiment includes a flat pouch 20 made of a bottomed barrier film and a flat sleeve 30 in which the pouch 20 is housed, and an upper end 21 a of the pouch is an upper end 31 a of the sleeve 30, Although it protrudes above 41a, the upper ends 31a and 41a of the sleeve 30 can also protrude above the upper end 21a of the pouch so that the pouch 20 is completely stored inside the sleeve 30.

<Conveyance state (unopened)>
In the pouch sleeve 10 of this embodiment, food is enclosed in the pouch 20 (not shown), and the upper end 21a thereof is sealed and flattened. By sandwiching the flat pouch 20 with a substantially flat sleep 30 in which only the bottom center folding line 40 is mountain-folded, an unopened conveyance state can be obtained. In this state, the thickness of the pouch sleeve 10 is very thin and the volume is small.

<Three-dimensional assembly (opened)>
First, the pouch sleeve 10 of the present embodiment opens the upper end 21a of the pouch 20 that is not yet opened. Next, a force is applied so that the bottom center fold line 40 moves upward, and at the same time, the bottom arch fold line 38 and the bottom arch fold line 48 are mountain-folded, and the bottom 34 and the bottom 44 become an arch-like continuous curved surface. In this way, both ends of the bottom center folding line 40 that has been folded in a mountain are flush with each other.

 At this time, the lower fold line 38a is a mountain fold, the leg portion 35c and the inner leg portion 35a are approached, the lower fold line 48a is a mountain fold, the leg portion 45c and the inner leg portion 45a are approached, and the lower fold line The leg part 35d and the inner leg part 35b are brought closer to each other by 38b as a mountain fold, and the leg part 45d and the inner leg part 45b are brought closer to each other by taking the lower fold line 48b as a mountain fold. At the same time, the bottom side fold line 39a is a valley fold, the inner leg 35a is deformed so as to protrude downward in the vertical direction from the bottom 34, the bottom side fold line 39b is a valley fold, and the inner leg 35b is The bottom side fold line 49a is deformed so as to protrude downward from the bottom 34, and the inner leg 45a is deformed so as to protrude downward from the bottom 44 in the vertical direction. The partial fold line 49b is a valley fold, and the inner leg 45b is deformed so as to protrude downward from the bottom 44 in the vertical direction.

  At the same time, a force is applied so that the side edge portion 36a and the side edge portion 36b of the sleeve 30 approach each other, and the sleeve 30 is contracted inward in the lateral direction, whereby the side edge fold line 37a becomes a valley fold, and the side fold line 37b, 37c is a mountain fold, side edge fold line 37d is a valley fold, and the front surface 32 and the rear surface 42 are moved so as to be separated in the front-rear direction, which is the thickness direction.

  The front sheet material (front surface) 21 and the rear sheet material (rear surface) 22 of the pouch 20 adhered to the front surface 32 and the rear surface 42 are in the thickness direction following the movement of the front surface 32 and the rear surface 42 spreading. The bottom sheet material (bottom part) 23 that has been folded in two at the center bottom fold line 24 is flattened while being moved away from each other in the front-rear direction, the space inside the pouch 20 is enlarged, and the upper end 21a is greatly opened. It becomes the made opening. Thus, by changing the sleeve 30 into a three-dimensional shape, the pouch 20 connected to the front surface 32 and the rear surface 42 of the sleeve 30 can be opened in a cylindrical shape.

 The leg 35c, the inner leg 35a, the leg 35d, and the inner leg 35b protrude downward in the vertical direction to form a double leg, and can be strong and stable by being grounded at four points. A pouch sleeve 10 can be obtained. Thereby, even when hot water is injected, it is possible to provide the pouch sleeve 10 that is safely independent.

Moreover, since it can be three-dimensionalized by one operation and can be locked so as to maintain the state, it can be easily opened and eaten easily.
At the same time, the finger-hanging portions 46c, 46d, 46e, and 46f are formed so as to protrude in the horizontal direction, so that the gripping can be stably performed, and the temperature of the contents can be held even when gripping / carrying with hot water injected. It is possible to prevent it from reaching the hands of the person.

 Next, the manufacturing method of the pouch sleeve 10 of this embodiment is demonstrated.

 First, as a sleeve preparation step, the outline of a paperboard or the like to be the sleeve 30 is formed so as to have a developed shape shown in FIG. 5 by a molding process such as punching. At the same time or thereafter, each fold line is formed as a fold line process. The sleeve 30 is folded in half from the bottom center folding line 40 so as to become the front piece 31 and the rear piece 41.

  Next, as the pouch preparation step, the long material made of the sheet material described above is folded with the center bottom fold line 24 being valley-folded and the front bottom fold line 25 and the front bottom fold line 26 being mountain-folded. Next, the upper end 21a is cut off and cut into a rectangular and trapezoidal outline, and the side ends 21b and 22b, the side ends 21c and 23c, and the side ends 22d and 23d are sealed by heating, pressure bonding, etc. 20

 Next, as a filling step, the pouch 20 is filled with a predetermined food material from the upper end 21a, and, for example, the upper end 21a is sealed together with the decompression process so that the pouch 20 is compressed into a flat shape.

 Next, as a sticking step, the flat pouch 20 is placed and positioned inside the folded sleeve 30, the front sheet material (front surface) 21 and the front surface 32 are adhered, and the rear sheet material (rear surface) 22. And the rear face 42 are attached. Finally, the side edges 21b and 22b of the pouch 20 and the side edge 36a and the side edge 36b of the sleeve 30 are attached, and the pouch sleeve 10 filled with food is manufactured in a transported state.

 In addition, as a manufacturing method of the pouch sleeve 10, it is also possible to fill the pouch 20 with a predetermined food material from the upper end 21a and seal it as a filling step after the sticking step.
