  Similarly, the 2nd bag-like field 2B and discharge part 3 can be connected by external force. Specifically, the 2nd bag-like field 2B and discharge part 3 are isolated by discharge part seal part S2 formed in the field between them. Then, by pressing the first bag-like region 2A and / or the second bag-like region 2B, when a force in the direction of peeling the base sheet 4 and the bulging film 5 is applied to the discharge part seal portion S2, As shown in FIG. 11, the material sheet 4 and the bulging film 5 are peeled off to form a discharge portion communication passage 2 </ b> D that connects the second bag-shaped region 2 </ b> B and the discharge portion 3.

  In the region between the first bag-like region 2A and the second bag-like region 2B, a weir portion that makes the width of the inter-region communication path 2C narrower than the width of the first bag-like region 2A and the second bag-like region 2B S4 is provided. The “width” of the first bag-like region 2A, the second bag-like region 2B, the inter-region seal portion S1, the inter-region communication path 2C, and the weir portion S4 is the second bag-like shape from the first bag-like region 2A. This refers to the width in the direction [vertical direction in FIG. 2 (a)] perpendicular to the liquid mixing direction toward the region 2B.

  FIG. 3 is a plan view schematically showing a configuration closely related to the dam portion S4 for convenience of explanation of the dam portion S4. As shown in FIG. 3, a pair of weir portions S4 are provided adjacent to the outer side in the width direction of the inter-region seal portion S1. The dam portion S4 is formed by sealing the base sheet 4 and the bulging film 5 with a seal strength higher than that of the inter-region seal portion S1, specifically with the same seal strength as that of the outer peripheral seal portion S3. Yes.

The pair of weir portions S4 have a line-symmetric shape in the width direction, preferably 3 to 10 mm, and more preferably 5 to 8 mm, along the liquid mixing direction. preferable. In the present embodiment, the dam portion S4 has substantially no roundness at the corner adjacent to the inter-region seal portion S1.
The total length of the width W3 of the pair of dam portions S4 is preferably 8 to 15% of the width W1 of the first bag-like region 2A and the second bag-like region 2B, and is 10 to 14%. Is more preferable. When the width W1 of the first bag-like region 2A and the second bag-like region 2B is 27 mm, for example, the width W3 of the pair of weir portions S4 is preferably 1 to 2 mm.

  The width W2 of the inter-region seal portion S1 (inter-region communication path 2C) can be set by appropriately setting the width W3 of the weir portion S4, and the width of the first bag-like region 2A and the second bag-like region 2B.

  The formation method of the inter-region seal part S1 and the discharge part seal part S2 is not limited, but, for example, a coating agent (for example, an EVA-based part coating agent) is applied to the base sheet 4 and swells after drying. The film 5 can be overlapped, and the base sheet 4 and the bulging film 5 can be formed by heat seal bonding with a coating agent interposed therebetween. Moreover, the area | region seal | sticker part S1 and the discharge part seal | sticker part S2 can also be formed by heat-seal-bonding the base material sheet 4 and the swelling film 5 with an easily peelable film interposed between them.

  The reason for heat sealing joining the base sheet 4 and the bulging film 5 by interposing the coating agent or the easily peelable film is that the base sheet 4 and the bulging film 5 are directly heat sealed. Compared to the case, the presence of the coating agent and the easily peelable film reduces the bonding strength between the base sheet 4 and the bulging film 5, and seal strength between the inter-region seal portion S <b> 1 and the discharge portion seal portion S <b> 2. Is made smaller than the sealing strength of the outer peripheral seal portion S3 and the weir portion S4.

When the bulging film 5 is made of a polyethylene sheet, the heat sealing temperature when forming the inter-region seal portion S1 and the discharge portion seal portion S2 is preferably 130 to 150 ° C. Moreover, the temperature of the heat seal at the time of forming outer peripheral seal part S3 and dam part S4 becomes like this. Preferably it is 150-240 degreeC.

The width of the discharge part seal part S2 is preferably narrower by 1 mm or more than the width of the inter-area seal part S1.

  As described above, the seal strength of the inter-region seal portion S1 and the seal strength of the discharge portion seal portion S2 can be made different by changing the width, but instead of or in combination with, for example, the coat It can also be made different by changing the physical properties, thickness, etc. of the agent or the easily peelable film, or by changing the heating temperature, heating time, etc. of the heat seal.

The seal strength of the inter-region seal portion S1 is such that the first storage portion 5A and / or the second bag-like region 2B of the bulge film 5 forming the first bag-like region 2A is formed during handling, transportation, and the like. In a situation where the second storage portion 5B of the exit film 5 is unintentionally pressed, the inter-region seal portion S1 does not peel off, and the first liquid F1 in the first bag-like region 2A and the second bag-like region 2B When mixing with the second liquid F2, when the first accommodating portion 5A of the bulging film 5 and / or the second accommodating portion 5B of the bulging film 5 is intentionally pressed, the inter-region seal portion S1 is peeled off. If the size is such that the inter-region communication path 2C is formed, it can be set to an appropriate size.
Specifically, the seal strength of the inter-region seal portion S1 is preferably 50 to 800 gf / 15 mm, more preferably 300 to 500 gf / 15 mm. The measurement of the seal strength is performed using a test piece having a width of 15 mm by a 180 degree peeling test according to JIS K6854-2.

The seal strength of the discharge portion seal portion S2 is such that the discharge portion seal portion S2 does not peel off when the first liquid F1 in the first bag-like region 2A and the second liquid F2 in the second bag-like region 2B are mixed. When the mixed composition in the second bag-like region 2B is discharged from the discharge port 3, the second concave portion 5B of the bulging film 5 forming the second bag-like region 2B is intentionally strongly pressed. Can be set to an appropriate size as long as the discharge portion seal portion S2 is peeled off and the discharge portion communication passage 2D is formed. Specifically, the seal strength of the discharge portion seal portion S2 is preferably 400 to 1000 gf / 15 mm, more preferably 700 to 900 gf / 15 mm.
The seal strength of the discharge portion seal portion S2 is preferably larger than the seal strength of the inter-region seal portion S1, and specifically, it is 300 gf / 15 mm or more larger than the seal strength of the inter-region seal portion S1. Preferably it is.

The seal strength of the outer peripheral seal portion S3 and the weir portion S4 is larger than the seal strength of the inter-region seal portion S1 and the discharge portion seal portion S2, and is a size on the premise that they do not peel off during use. Specifically, the seal strength of the outer peripheral seal portion S3 and the weir portion S4 is preferably 1500 gf / 15 mm or more, and more preferably 2500 gf / 15 mm or more.
The outer peripheral seal portion S3 and the weir portion S4 are not limited in the formation method.
