Therefore, for example, if the page is rotated 90 degrees, "left and right" and "up and down" are read interchangeably, and of course, if the page is rotated 180 degrees, "left" becomes "right" and "right" becomes "left."

[0012] (First embodiment) <Pouch containing contents> As shown in FIG. 1, the content-sealing pouch 1 has a pouch 2 and a content 3 . In the following description, the width direction of the pouch 2 (left-right direction in Figure 1) may be referred to as a direction perpendicular to the height direction of the pouch 2 (up-down direction in Figure 1) when viewed from the front.

[0013] The specific configuration of the pouch 2 will be described later. The contents 3 are, for example, liquid seasoning, and are contained inside the pouch 2.

[0014] <Pouch> The structure of the pouch 2 will be described below with reference to FIG. The pouch 2 has the form of a standing pouch and includes a bag body 100 and a fastener part 200.

[0015] <Bag body> The bag body 100 is formed using a laminated sheet, and has a bag main body portion 10, a bag cut-out portion 20, a vapor-passing portion 30, a cut portion 40, and a cut portion 50.

[0016] The laminated sheet has, for example, an outermost layer, an intermediate layer, and an innermost layer. The outermost layer is, for example, composed of a polyethylene terephthalate layer. The innermost layer is, for example, composed of an unstretched polypropylene layer. The middle layer is, for example, composed of a printed layer, a first adhesive layer, an oriented nylon layer, and a second adhesive layer. The printed layer is formed inside the outermost layer. The first adhesive layer is formed inside the printed layer. The oriented nylon layer is formed inside the first adhesive layer. The second adhesive layer is formed inside the oriented nylon layer. The innermost layer is formed inside the second adhesive layer. The printed layer has a pattern, a product description, etc. on its outer surface.

[0017] The bag body 10 is a bag formed in a rectangular shape. In addition, the bag body 10 has an internal space 10S, a first opening 11, and a second opening 12 formed therein.

[0018] The internal space 10S is a space formed inside the bag body 10, and is a space capable of accommodating the contents 3. The first opening 11 is an opening that connects the internal space 10S with the outside, and is formed on one side (upper side 10U) of the bag body portion 10.

[0019] The second opening 12 is an opening that connects the internal space 10S with the outside, and is formed on one side (the left side 10L in FIG. 1) of the bag main body 10 that is adjacent to the side on which the first opening 11 is formed. In addition, the second opening 12 has the function of storing the contents 3 in the internal space 10S during the manufacturing process of the content sealing pouch 1. All edges (sides) of the bag body 10 are sealed, including the portions where the first opening 11 and the second opening 12 are formed. The hatching shown in FIG. 1 indicates a sealed portion 60 of the bag body 10. The seal portion 60 is formed by, for example, heat welding.

[0020] The bag cutout portion 20 is formed on one side of the bag main body portion 10 that forms the first opening 11, and includes a seal portion 60 that blocks the first opening 11 and a space portion that forms the first opening 11. The bag incision portion 20 also includes a pair of notches 21 and an opening guide line 22 .

[0021] The pair of notches 21 are formed on two sides (left side 10L and right side 10R in FIG. 1) of the bag body 10 that are adjacent to the side on which the first opening 11 is formed. The pair of notches 21 are both formed at positions that are equidistant from the upper side 10U. The opening guide line 22 is disposed at a position continuous with the pair of cutouts 21, and is formed by, for example, performing half-cut processing using a laser on the laminated sheet that constitutes the bag body 10. As a result, the opening guide line 22 has the function of separating the bag cutout portion 20 from the first opening 11. Therefore, the first opening 11 has the function of storing the contents 3 in the internal space 10S in a state in which the bag cut-out portion 20 is separated from the bag main body portion 10.

[0022] The vapor passage section 30 is a section for releasing vapor from the internal space 10S, and is formed as a section that connects the internal space 10S with the outside. The vapor passage portion 30 is disposed on one side (left side 10L or right side 10R) of the bag body 10 adjacent to the side (upper side 10U) on which the first opening 11 is formed. In the first embodiment, a case where the vapor passage portion 30 is disposed on the right side 10R of the bag body portion 10 will be described as an example.

[0023] The cutting portion 40 forms part of the bag main body portion 10, and is formed to connect one side (top side 10U) on which the first opening 11 is formed and the two adjacent sides (left side 10L and right side 10R), and is parallel to the length direction of the top side 10U (left-right direction in Figure 1). Specifically, the cutting portion 40 is formed using CPP (Cast Polypropylene: unstretched polypropylene) that has straight cutting properties (linear cutting performance).

[0024] In the first embodiment, as an example, a case will be described in which the cutting portion 40 is formed using "DC061" (for example, 60 μm thick) manufactured by Toyobo Co., Ltd., which is a CPP. As shown in FIG. 1, the cutting portion 40 is not perforated, but is formed in a line or band shape.

[0025] In addition, the cutting portion 40 is formed at a position within a range of 75 mm or more and less than 120 mm from the side (top side 10U) of the bag main body portion 10 on which the first opening 11 is formed and the side (bottom side 10D) different from the left side 10L and right side 10R adjacent to the top side 10U. The tear strength of the cut portion 40 is 1 [N] or less.

[0026] The tear strength of the cut portion 40 is the tear strength along the width direction of the bag body portion 10 (the left-right direction in FIG. 1). As described above, the cutting portion 40 forms a portion for separating the bag main body portion 10 into an upper portion which includes the first opening 11 and the zipper portion 200, and a lower portion which is the other portion, by cutting a portion of the bag main body portion 10.

[0027] The notch 50 is a notch formed continuously with the cut portion 40 . The cutout 50 is arranged on the same side (right side 10R) of the bag body 10 as the vapor passage section 30. As a result, the incision portion 50 functions as a starting point when the bag body portion 10 is separated along the cutting portion 40 into an upper portion and a lower portion.

[0028] <Zipper section> The fastener portion 200 is disposed between the first opening 11 and the internal space 10S with respect to the bag body portion 10, and is capable of opening or sealing the first opening 11. The distance between the cutting portion 40 and the fastener portion 200 is 4 mm or more. In the first embodiment, as an example, a case where the distance between the cutting portion 40 and the fastener portion 200 is set to 4 mm will be described.

[0029] <Manufacturing method> Hereinafter, a method for manufacturing the content sealing pouch 1 will be described with reference to FIG. The method for manufacturing the content sealing pouch 1 includes a first step, a second step, a third step, and a fourth step.

[0030] In the first step, the pouch 2 is produced. In the second step, the edges (sides) of the bag body 10 excluding the portion where the second opening 12 is formed are sealed.

[0031] In the third step, a nozzle is inserted into the second opening 12, and the contents 3 are filled into the internal space 10S through the nozzle. In the fourth step, the second opening 12 is sealed.

[0032] <How to use> Hereinafter, with reference to FIG. 1, a method of using the content sealing pouch 1 will be described. First, the bag cut-out portion 20 is separated from the bag body portion 10, and then the first opening 11 is opened by the fastener portion 200.

[0033] Then, ingredients such as meat and vegetables are placed in the internal space 10S in which the contents 3 are accommodated, and then the first opening 11 is sealed with the fastener part 200. Thereafter, the bag body 10 is heated using a microwave oven or the like to cook the ingredients including the contents 3.

[0034] After cooking is completed, the pouch 2 is placed upright on a table or the like, and the cut portion 40 is cut to separate the bag body 10 into an upper portion and a lower portion. Then, the ingredients contained in the lower portion, including the contents 3, are eaten using chopsticks or the like.

[0035] The above-described first embodiment is one example of the present invention, and the present invention is not limited to the above-described first embodiment. Various modifications can be made depending on the design, etc., even in forms other than the first embodiment, as long as they do not deviate from the technical idea of ​​the present invention.

[0036] (Effects of the first embodiment) The pouch 2 of the first embodiment can achieve the following effects. (1) The bag body 100 includes an internal space 10S capable of accommodating contents 3, a first opening 11 connecting the internal space 10S to the outside, and a fastener portion 200 disposed between the first opening 11 and the internal space 10S and capable of opening or sealing the first opening 11. The bag body 100 also includes a rectangular bag body 10 in which the internal space 10S is formed and the first opening 11 is formed on one side (top side 10U), and a vapor passage portion 30 for releasing vapor from the internal space 10S. In addition, the bag body 100 includes a cutting portion 40 for cutting a portion of the bag body 10 to separate the bag body 10 into a portion (top) including the first opening 11 and the fastener portion 200 and another portion (bottom). The vapor passage portion 30 is disposed on at least one of two sides (right side 10R, left side 10L) adjacent to one side of the bag body 10. Furthermore, the cut portion 40 is formed so as to connect two adjacent sides (the right side 10R and the left side 10L) and to be parallel to the length direction of one side (the upper side 10U).

[0037] As a result, the cutting section 40, which is formed parallel to the longitudinal direction of the first opening 11, can be cut linearly across the right side 10R and the left side 10L, making it possible to provide a pouch that can be cut linearly. Furthermore, since the fastener portion 200 is provided, it is possible to open the first opening 11, place ingredients into the internal space 10S, and then reseal the pouch 2, and cook the ingredients using a microwave oven or the like. Furthermore, by providing the steam passage section 30, even if the pressure in the internal space 10S increases due to the generation of steam accompanying the heating of ingredients including the contents 3 when heated using a microwave oven or the like, the steam in the internal space 10S is released to the outside via the steam passage section 30. This prevents the bag body 100 from expanding excessively, making it possible to shorten the cooking time.

[0038] (2) The cut portion 40 is formed at a position within a range of 75 mm or more and less than 120 mm from the side (lower side 10D) different from one side and two sides of the bag body portion 10. As a result, when the cutting portion 40 is cut, the ingredients including the contents 3 are held at the bottom, making it possible to easily remove the ingredients including the contents 3 from the pouch 2 after cooking.

[0039] (3) The distance between the cutting portion 40 and the fastener portion 200 is 4 mm or more. As a result, when the cutting portion 40 is cut, the ingredients including the contents 3 are held at the bottom, making it possible to easily remove the ingredients including the contents 3 from the pouch 2 after cooking.

[0040] (4) The tear strength of the cut portion 40 is 1 [N] or less. As a result, compared to a configuration in which the tear strength of the cutting portion 40 exceeds 1 [N], it becomes easier to cut the cutting portion 40 in a straight line.

[0041] (5) The bag body 100 further has a cut portion 50 formed continuously with the cut portion 40, and the cut portion 50 is disposed on the same side as the vapor passage portion 30. As a result, the incision portion 50 functions as the starting point when separating the bag main body portion 10 into an upper and lower portion along the cutting portion 40, making it easier to cut the cutting portion 40 compared to a configuration that does not have the incision portion 50.

[0042] The content sealing pouch 1 of the first embodiment can achieve the effects described below. (6) It has a pouch 2 and contents 3 contained in the pouch.

[0043] As a result, it is possible to provide a content-sealing pouch that can be cut in a straight line. In addition, by cutting the cutting portion 40 and separating the pouch 2 after cooking into an upper and lower portion, it becomes possible to eat ingredients including the contents 3 using the pouch 2 without the need for a plate or the like.

[0044] <Modification of the first embodiment> (1) In the first embodiment, the vapor passage section 30 is configured to be arranged on the right side 10R of the bag body 10, but this is not limited to this. That is, the vapor passage section 30 may be configured to be arranged on at least one of the two sides (left side 10L, right side 10R) adjacent to the one side (upper side 10U) on which the first opening 11 is formed, of the bag body 10. [Example]

[0045] With reference to the first embodiment, the content-sealed pouches of Examples 1 to 3, the content-sealed pouches of Comparative Examples 1 and 2, and the content-sealed pouches of Reference Examples 1 to 3 will be described below.

[0046] Example 1 The cut portion was formed using "DC061" having a thickness of 60 μm, manufactured by Toyobo Co., Ltd. At this time, no perforations were formed in the cut portion. The height of the cut portion from the bottom end surface was set to 90 mm. The distance between the fastener portion and the cut portion was set to 4 mm. In this way, the content-sealing pouch of Example 1 was formed.

[0047] Example 2 A content sealing pouch of Example 2 was formed in the same manner as in Example 1, except that the height of the cut portion from the lower end surface was set to 80 [mm].

[0048] Example 3 A content sealing pouch of Example 3 was formed in the same manner as in Example 1, except that the height of the cut portion from the lower end surface was set to 110 mm.

[0049] (Comparative Example 1) The content-sealing pouch of Comparative Example 1 was formed in the same manner as in Example 1, except that the cut portion was formed using "ZK507" manufactured by Toray Film Processing Co., Ltd., which has a thickness of 60 μm, and that perforations were formed in the cut portion.

[0050] (Comparative Example 2) The content-filled pouch of Comparative Example 2 was formed in the same manner as in Example 1, except that the cut portion was formed using "ZK207" manufactured by Toray Film Processing Co., Ltd., which has a thickness of 60 μm.

[0051] (Reference example 1) A content sealing pouch of Reference Example 1 was formed in the same manner as in Example 1, except that the height of the cut portion from the lower end surface was set to 70 mm.

[0052] (Reference example 2) A content sealing pouch of Reference Example 2 was formed in the same manner as in Example 1, except that the height of the cut portion from the lower end surface was set to 120 mm.

[0053] (Reference example 3) A content sealing pouch of Reference Example 3 was formed in the same manner as in Example 1, except that the distance between the fastener portion and the cut portion was set to 3 mm.

[0054] (Performance evaluation, evaluation results) The tear strength, ease of cutting, ease of removing ingredients, volume of the lower part of the pouch, and height of the contents were evaluated for each of the content-sealed pouches of Examples 1 to 3, Comparative Examples 1 and 2, and Reference Examples 1 to 3. The evaluation results are shown in Table 1. The evaluation methods used were as follows.

[0055] <Tear strength> The tear strength was evaluated by an actual measurement value, that is, the tear strength was measured when the cut portion of the content-sealing pouch was cut in the lateral direction (horizontal direction) and evaluated.

[0056] <Ease of cutting> The ease of cutting was evaluated based on the ease of cutting when the cut portion was cut to separate the pouch into an upper portion and a lower portion. If it was possible to cut in a straight line in the horizontal direction, it was evaluated as "◎", if it was possible to cut but required a lot of force, it was evaluated as "◯", and if the cut included the zipper part, it was evaluated as "×".

[0057] <Easy to remove ingredients> The ease of removing the ingredients was evaluated based on the ease of removing the contents when the pouch was separated into upper and lower halves. The evaluators then rated the product as "◎" if the contents could be easily removed using chopsticks, as "◯" if the contents could be removed but it required some effort, and as "×" if it was difficult to hold the contents using chopsticks.

[0058] <Capacity at the bottom of the pouch> The capacity of the lower part of the pouch was evaluated based on the state in which the contents were retained when the pouch was separated into upper and lower parts. When the pouch was separated into an upper and lower part, if the contents were held comfortably in the lower part, it was evaluated as "◎", if the contents were held in the lower part but the liquid level was unstable, it was evaluated as "〇", and if the liquid level overflowed from the lower part, it was evaluated as "×".

[0059] <Contents height> The height of the contents was evaluated by actual measurement, that is, the height from the bottom of the pouch to the top of the contents was measured for the pouch containing the contents. [Table 1]

[0060] As a result of evaluating various performances using the above-mentioned methods, the content-sealing pouches of Examples 1 to 3 exhibited excellent performance in each evaluation item. On the other hand, the content-sealing pouch of Comparative Example 2 was unable to exhibit excellent performance in terms of ease of cutting. Furthermore, the content-sealing pouch of Comparative Example 1 has perforations formed in the cut portion, making it easier to cut than the content-sealing pouch of Comparative Example 2. However, because the cut portion has perforations, the perforations are less durable against the increase in pressure that occurs in the internal space of the pouch when heated, for example, in a microwave oven, making it difficult to satisfy the requirements for a content-sealing pouch. Therefore, the content-sealing pouch of Comparative Example 1 has difficulty satisfying the requirements for a content-sealing pouch used for heating an object (such as food) contained in the internal space.

[0061] The present technology can be configured as follows. (1) A bag body having an internal space capable of accommodating contents and a first opening that connects the internal space to the outside; a fastener portion disposed between the first opening and the internal space and capable of opening or sealing the first opening, The bag body is a rectangular bag body portion in which the internal space is formed and the first opening is formed on one side; a vapor passage portion for extracting vapor from the internal space; a cutting portion for separating the bag main body portion into a portion including the first opening and the fastener portion and other portions by cutting a portion of the bag main body portion, The vapor passage portion is disposed on at least one of two sides of the bag body portion adjacent to the one side, The cut portion is formed to connect the two adjacent sides and parallel to the longitudinal direction of one of the sides. (2) The pouch according to (1) above, wherein the cut portion is formed at a position within a range of 75 mm or more and less than 120 mm from the one side and the side other than the two sides of the bag main body. (3) The pouch according to (1) or (2) above, wherein the distance between the cut portion and the fastener portion is 4 mm or more.
