Description

  The present invention relates to a paper outer box for accommodating a sealed bag containing food.

  Advances in sterilization technology have emerged as a packaged cooked food that can be stored for a long time. In addition to this, with the spread of microwave ovens, many foods that can be easily eaten simply by heating in the microwave oven are being sold. As this type of food, cooked curry, stew, pasta sauce and the like can be exemplified, and a typical example is a retort food. Retort food is stored in a retort pouch and sold in a state where a sealed retort pouch is placed in a paper outer box.

  Two methods are known when heating using a microwave to eat retort food. The first method is a method in which the pouch taken out from the outer box is opened, the contents are transferred to a dish, and the dish is wrapped and heated in a microwave oven. The second method is a method in which the retort pouch is taken out from the outer box, and after the retort pouch is heated in a microwave oven, the contents, that is, the food, is transferred from the range pouch to tableware such as a plate for eating.

  In the second method, when the pouch sealed with food is heated in a microwave oven, the pressure inside the pouch may rise and burst. For this reason, the retort pouch has been devised in various ways, for example, when the internal pressure reaches a certain level or higher, the seal at one corner peels off to relieve the pressure (Patent Document 1). . However, if the retort pouch is heated with a microwave oven in a horizontal state, the contents may leak out of the retort pouch together with the relief of the internal pressure. For this reason, in addition to flat bags, retort pouches have been put to practical use as standing pouches that can stand up. However, even if it is a standing pouch, since the raw material is made of a flexible material, there is a possibility of falling down while heating in a microwave oven. For this reason, a support for holding the retort pouch in an upright state has been proposed (Patent Documents 2 and 3).

  Today, food habits are also diversifying, and there is a tendency to diversify the product development of packaged foods that can be easily eaten anywhere.

  An object of the present invention is to provide a paper outer box for housing a sealed bag containing food, which can provide a new eating method for packaged food.

  A further object of the present invention is to provide a function as a tableware at the time of eating as an additional function to a paper outer box that has been generally used for the outer packaging of food-sealed sealed bags. An object of the present invention is to provide a paper outer box for housing a sealed bag containing food.

  A further object of the present invention is to hold the pouch in an upright state when heated in a microwave oven as an additional function to the paper outer box that has been conventionally used for the outer packaging of sealed bags containing food. An object of the present invention is to provide a paper outer box for housing a sealed bag containing food, which can be provided with a function as a supporting tool.

  A further object of the present invention is to provide a function as a tableware and a support as described above without changing the basic design of a paper and flat rectangular parallelepiped box which is generalized as an exterior box of a retort pouch. An object of the present invention is to provide a paper outer box for housing a sealed bag containing food that can be applied.

The above technical problem is, according to the first aspect of the present invention, with reference to FIGS.
In a paper outer box (1) for containing a rectangular parallelepiped-shaped food bag having six surfaces including a front surface (1a) and a back surface (1b),
A weakening line (4) capable of dividing the outer box (1) into first and second halves (2, 3);
A peripheral fold line (7) extending over the entire circumference at a position spaced from the end face (6) facing the opening (5) of the first half (2) or the second half (3);
A total of 4 connecting the intersections (P1) located inward by a predetermined distance from each end of the peripheral fold line (7) on the front surface (1a) and the back surface (1b) and each corner of the end surface (6). Provided is a paper outer box (1) for containing a food-sealed sealing bag, characterized by having a crease formation inducing means for inducing the formation of a crease at a virtual inclined straight line (FL1) of books. Is achieved.

The above technical problem is, according to the second aspect of the present invention, with reference to FIGS.
(1) In the outer packaging box (1) made of a rectangular parallelepiped shape having six faces including the rear face (1b) and for containing the sealed bag containing food,
A weakening line (4) capable of dividing the outer box (1) into first and second halves (2, 3);
A peripheral fold line (7) extending over the entire circumference at a position spaced from the end face (6) facing the opening (5) of the first half (2) or the second half (3);
A total of 4 connecting the intersections (P1) located inward by a predetermined distance from each end of the peripheral fold line (7) on the front surface (1a) and the back surface (1b) and each corner of the end surface (6). This is accomplished by providing a paper outer box for containing a sealed bag containing food, characterized by having a weakening line or a cutting line (12) consisting of a curved line.

  The invention according to the first aspect will be described below. FIG. 1 is a developed view of the outer box, and FIG. 2 is a perspective view of the outer box. The outer box (1) has a cubic shape with six surfaces, and the illustrated example is a conventionally known relatively flat paper box for housing a retort pouch. By cutting along the weakening line (4) with reference to FIG. 2, the outer box (1) can be divided into two halves (2) and (3). The unsealed sealing bag accommodated in the box (1) can be taken out.

  The sealed bag contains food. This food may be a cooked food, a semi-food that can be cooked by heating in a microwave oven, or opening a sealed bag and placing a predetermined amount of milk or raw egg in the bag. It may be a semi-food product that becomes a food product by stirring with a spoon.

  Therefore, the sealed bag is a bag that can contain and seal food in a broad sense including semi-food, and a typical example is a retort pouch. This sealing bag may have a flat shape or may have a standing property like a standing pouch.

  The half (2) shown in FIG. 3 is shown in FIGS. 4 and 5 in accordance with a second fold line (reference numeral 8 in the embodiment) on its surrounding fold line (7) and a virtual inclined straight line (FL1) as a typical example. As shown in FIG. 6, the bottomed box (22) formed by crease as shown in the figure has both ends of the bottom (20) obtained by enlarging the elongated rectangular end face (6) (FIG. 2) in the width direction. Have a pair of bottom flaps (21), (21). That is, the bottomed box (22) has a seat surface that is enlarged in the width direction and the longitudinal direction, and an opening (23) that has a large opening (FIG. 6). Of course, the second folding line on the virtual inclined straight line (FL1) may be a cutting line or a weakening line instead.

  If the bottomed box (22) is a retort pouch with a sealed bag containing cooked curry, the retort pouch is erected by placing the retort pouch in the bottomed box (22) and heating it with a microwave oven. The bottomed box (22) can be made to function as a support tool to be held on.

  In addition, when taking out from the microwave oven, the bottomed box (22) containing the retort pouch is made of paper, so that the bottomed box (22) is made of paper, so it is insulated from the microwave oven with bare hands. be able to.

  In this state, when the upper end of the retort pouch is cut off and the retort pouch is opened, while holding the bottomed box (22) with bare hands or with the bottomed box (22) placed on the table, You can eat the contents of the retort pouch using a spoon. Therefore, the bottomed box (22) can function as a kind of tableware.

  This also applies to foods that can be eaten simply by opening the sealed bag taken out of the outer box (1) .After making the bottomed box (22), the opened bag is put into the bottomed box (22). The contents in the bag can be eaten using a spoon, fork or the like while holding the bottomed box (22) or with the bottomed box (22) placed on the table. Of course, it goes without saying that the sealed bag may be opened after being placed in the bottomed box (22).

  Further, the width 130 mm × length 160 mm × depth 25 mm shown in FIG. 2 is a dimension of a conventionally known flat outer box. When the present invention is applied to such an outer box, the basic of the outer box is shown. The exterior box (1) according to the present invention can be made simply by adding a weakening line (4), a surrounding folding line (7), etc. .

  The weakening line (4) for dividing the outer box (1) into two halves (2) and (3) is two weakenings extending in parallel and adjacent to each other, as can be seen from FIGS. It may be a zipper (reference numeral 24 in FIG. 22) formed by the lines (4) and (4). Moreover, you may comprise from a conventionally well-known perforation (FIG. 7). Of course, the weakening line (4) does not necessarily have to be a straight line, and an arbitrary shape such as an arch shape, a waveform, or a sawtooth shape can be adopted. Visual interest can be provided to the opening edge of (22).

  With reference to FIG. 8, the basic concept of the method of forming the seat surface expanded in the width direction and the longitudinal direction using the half (2) or (3) will be described. In each of the front face (1a) and the back face (1b) of the outer box (1), the rectangular area S1 at the two corners is a part forming the bottom flap (21), and the two corner areas S1, S1 The sandwiched intermediate region S2 is a portion that creates a seating surface that is expanded in the width direction. Therefore, the corner area S1 and the intermediate area S2 can be considered separately.

  First, the peripheral fold line (7) is a fold line at the center between the fold line portion (7a) outside the intersection (P1) where the virtual inclined straight line (FL1) intersects and the left and right intersections (P1, P1). It can be divided into part (7b). Here, the area surrounded by the outer fold line portion (7a) in the peripheral fold line (7) and the perpendicular (H) of the intersection (P1) is the corner area (S1), and the peripheral fold line (7 ) Is a middle region (S2) surrounded by a central fold line portion (7b) and left and right vertical lines (H, H). As described above, since the corner corner region (S1) is a region forming the bottom flap (21), in order to form the bottom flap (21) on the same plane as the other seating surfaces, the outer folding line is formed. (7a) should be parallel to the end face (6) of the outer box, and most preferably, the corner area (S1) should be square. Then, a crease formation guiding means may be provided so that a crease along the virtual inclined straight line (FL1) can be formed in the corner area (S1) when the half (2) or (3) is operated.

  A typical example of the crease formation guiding means is to provide a fold line, weakening line, and cutting line on the virtual inclined straight line (FL1). It does not need to extend over and may be partial. For example, a fold line or the like may be provided only in the vicinity of the intersection (P1) on the virtual inclined straight line (FL1) in contact with the intersection (P1).

  9 to 14 show some examples A1 to A6 of the crease formation guiding means. FIG. 9 shows a fold line, a weakening line, and a cutting line A1 extending upward from the intersection point P1. FIG. 10 shows a fold line, a weakening line, and a cutting line A2 extending obliquely inward from the intersection P1. FIG. 11 shows a void A3 having one vertex at the intersection P1. FIG. 12 shows a fold line, a weakening line, and a cutting line A4 extending in a V shape from the intersection point P1. FIG. 13 shows a crease formation guiding means A5 having a fold line, a weakening line, and a cutting line extending upward in addition to a fold line, a weakening line, and a cutting line extending in a V shape from the intersection P1. FIG. 14 shows a fold line, a weakening line, and a cutting line A6 extending in a double V shape from the intersection point P1.

  The intermediate region (S2) is a region for forming a seat surface that is expanded in the width direction, but the central fold line portion (7b) of the peripheral fold line (7) is parallel to the end surface (6) of the exterior box. It may be a straight line extending or an arched curve. For example, if it is configured with an arch-shaped curve that protrudes upward (convex toward the side opposite to the end face (6)) with the central fold line part (7b) facing upward, the arch that protrudes outward A seating surface with a contour can be formed.

  15 to 21 illustrate some typical examples of how to make the bottom of the bottomed box (22) made from the half (2) or (3).

  As shown in FIG. 15 and FIG. 16, an example in which the fold line portion outside the point (P1) with respect to the surrounding fold line (7) is configured by a weakening line or a cutting line (11) is shown. Even if there is no fold line etc. in FL1), not only can it be induced to form a fold with a virtual inclined straight line (FL1), but the bottom flap (21) of the bottomed box (22) can be flattened. Easy to fold.

  As shown in FIGS. 17 and 18, on the opposite side to the end face (6), that is, the corner corner area (S1) and / or the intermediate area (S2) across the peripheral fold line (7), A void (10) having the intersection (P1) as a vertex may be formed. By using the space (10) with the intersection (P1) as the apex and the corner (P2) of the outer box, as described above, the space (10) can be provided without any fold line or the like on the virtual inclined straight line (FL1). Thus, it is possible to configure a crease formation guiding means for guiding the formation of a crease with a virtual inclined straight line (FL1) connecting the point (P1) and the corner (P2) of the outer box. In addition, the edge of the peripheral wall is defined by the side of the void (10) extending to the area opposite to the end face (6) across the peripheral fold line (7) (that is, the area constituting the peripheral wall of the bottomed box (22)). Bending can be induced (FIG. 18).

  FIGS. 19-21 shows the example which provided the weakening line or cutting line (12) extended between an intersection (P1) and a corner | angular part (P2) in a corner corner area | region (S1) as a modification.
