Summary of the Invention

Problems to be Solved by the Invention

[0004] In the pouch container described in Patent Document 1, since the notch for liquid discharge and the opening line are provided at the upper part of the container, the liquid cannot be separated from the solid substance and discharged unless the container is turned upside down.

[0005] An object of the present invention is to provide a pouch container capable of separating and discharging a liquid from a solid substance without turning the container upside down.

Means for Solving the Problems

[0006] The pouch container of the present invention includes a bottom portion formed to be concave downward, a first opening line that extends across the bottom portion from a first notch formed at a side end portion and forms a liquid discharge port at the bottom portion, and a second opening line that extends above the first opening line from a second notch formed above the first notch at the side end portion and forms a solid substance discharge port having a larger opening than the liquid discharge port.

[0007] According to the present invention, since the first opening line that forms the liquid outlet extends across the bottom portion which is formed to be concave downwards, the first opening line can form a liquid outlet at the bottom of the container, and the liquid can be separated from the solids and discharged without having to invert the pouch container.

[0008] The pouch container of the present invention is a self-standing pouch with a gusseted bottom, and the first opening line may be formed by creating a liquid outlet at the bottom of the standing pouch.

[0009] According to the present invention, even when the pouch container is a standing pouch, a liquid outlet is formed at the bottom, so the liquid can be separated from the solids and discharged without having to invert the standing pouch. [Brief explanation of the drawing]

[0011] One embodiment of the present invention will be described below with reference to the drawings. In the following descriptions, when directions are indicated, "up" refers to the Z-axis direction and "down" refers to the opposite direction; "left" refers to the X-axis direction and "right" refers to the opposite direction; and "front" refers to the Y-axis direction and "back" refers to the opposite direction. Furthermore, in subsequent embodiments, those with the same configuration and function as those already described will be given the same number as the embodiment, or their illustrations will be omitted, and their descriptions will be simplified or omitted.

[0012] In Figures 1 and 2, the pouch container 1 is a container that holds solid matter SD together with liquid LD (see Figure 3). Examples of solid matter SD to be held include cheese such as mozzarella, fruits, and konjac. Examples of liquid LD to be held include water, oil, and syrup.

[0013] The pouch container 1 comprises a pair of side sections 2 that constitute the body 2A, a bottom section 3, a first opening line 4, and a second opening line 5.

[0014] In this embodiment, the pouch container 1 is a standing pouch with a gusseted bottom 3. A bottom-forming sheet, folded over at its top so that it forms a mountain fold, is inserted between the lower ends of a pair of side portions 2, and these peripheries are sealed. The folded bottom-forming sheet has a non-sealed area 3A enclosed in a roughly arc shape from both ends of the mountain fold to the lower center, and the remaining area is a sealed area 3B. The non-sealed area 3A constitutes the bottom 3, and the sealed area 3B is bonded to the lower sealed area 23 of the side portion 2. Roughly semicircular notches 3C are formed at both the left and right ends of the bottom-forming sheet, and the side portions 2 are directly bonded to each other at the position of these notches 3C without the bottom-forming sheet in between.

[0015] The side section 2 comprises an upper sealing section 21 provided at the top, a side sealing section 22 provided at the side end, and a lower sealing section 23 provided at the bottom. The upper sealing sections 21 of the pair of side sections 2 are bonded together to seal the top of the body section 2A, and the side sealing sections 22 are bonded together to seal the side ends of the body section 2A. The sealing section 3B of the bottom-forming sheet is bonded to the lower sealing section 23, and the bottom of the body section 2A is sealed by the bottom section 3, which is made up of the non-sealed section 3A of the sheet.

[0016] The bottom portion 3 is formed to be concave downwards when it contains solid material SD or liquid LD. In this embodiment, since the pouch container 1 is a standing pouch, the bottom portion 3 has a concave shape that is concave downwards.

[0017] The first opening line 4 is extended across the bottom 3 from the first notch 41 formed in the side seal portion 22 which is a side end portion in each side surface portion 2, and forms a liquid discharge port 42 (see FIG. 3) in the bottom 3. The first opening line 4 is extended so that the minimum opening width W of the liquid discharge port 42 is smaller than the size of the solid matter SD. If the liquid discharge port 42 is circular, the diameter of the liquid discharge port 42 becomes the minimum opening width W.

[0018] In the case of this embodiment, in a front view when the pouch container 1 is viewed from the front, the left - right width of the liquid discharge port 42 is the minimum opening width W, and the minimum opening width W is smaller than the size of the solid matter SD. Also, the first notch 41 is formed in a region corresponding to the notch 3C in the side seal portion 22.

[0019] The second opening line 5 is extended above the first opening line 4 from the second notch 51 formed above the first notch 41 of the side seal portion 22 in each side surface portion 2, and forms a solid matter discharge port 52 (see FIG. 4) having a larger opening than the liquid discharge port 42.

[0020] In the case of this embodiment, the second opening line 5 is extended across the body portion 2A and forms the solid matter discharge port 52 in the body portion 2A.

[0021] The first opening line 4 and the second opening line 5 may be in a solid line shape or a broken line shape. Also, the first opening line 4 and the second opening line 5 may be constituted by, for example, a half - cut provided in the side surface portion 2, or the side surface portion 2 may be constituted by a uniaxially stretched film and cut in the stretching direction.

[0022] The procedure for opening the above - mentioned pouch container 1 and taking out the solid matter SD will be described. First, grasp the portion below the first notch 41 in the side seal portion 22 and pull the portion in a direction substantially parallel to the first opening line 4 to cut the first opening line 4 starting from the first notch 41. As a result, as shown in FIG. 3, a liquid discharge port 42 smaller than the size of the solid matter SD is formed in the bottom 3, so that the liquid LD can be discharged from the liquid discharge port 42 without inverting the pouch container 1 upside down.

[0023] Subsequently, the portion of the side seal portion 22 below the second notch 51 is grasped, and this portion is pulled in a direction approximately parallel to the second opening line 5, thereby cutting the second opening line 5 starting from the second notch 51. As a result, as shown in Figure 4, a solid waste outlet 52 larger than the size of the solid waste SD is formed in the body portion 2A, so that the solid waste SD can be discharged from the solid waste outlet 52 and removed without having to invert the pouch container 1.

[0024] According to the embodiment described above, since the first opening line 4 extends across the bottom portion 3 which is formed to be concave downwards, the first opening line 4 can form a liquid outlet 42 in the bottom portion 3 of the pouch container 1, and the liquid LD can be separated from the solid matter SD and discharged without having to invert the pouch container 1.

[0025] As described above, the best configurations, methods, etc., for carrying out the present invention are disclosed in the above description, but the present invention is not limited thereto. That is, although the present invention is mainly illustrated and described in relation to specific embodiments, those skilled in the art can make various modifications to the embodiments described above in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and objectives of the present invention. Furthermore, the descriptions of shapes, materials, etc. disclosed above are illustrative to facilitate understanding of the present invention and do not limit the present invention, so descriptions of components with some or all of those limitations removed are included in the present invention.

[0026] The pouch container 1 does not have to be a standing pouch; for example, as shown in Figure 5, it may be a flat bag type in which the side ends and bottom of a pair of side sections 2 are directly bonded together. In this case, the bottom section 3 is not a concave shape that is recessed downwards, but rather a curved shape that is recessed downwards.

[0027] The material of the sheet used to form the side portion 2 and the bottom portion is not particularly limited as long as it is capable of containing the solid SD and liquid LD inside the pouch container 1, and may be made of, for example, a resin film or aluminum foil.

[0028] The first opening line 4 and the second opening line 5 may extend in a direction that is inclined diagonally with respect to the left-right direction, or they may extend parallel to each other, or they may not extend parallel to each other.

[0029] The second opening line 5 only needs to be able to form a solid waste outlet 52 of a size that allows solid waste SD to pass through. For example, it may extend above the first opening line 4 and cross the bottom 3, and a solid waste outlet 52 that allows solid waste SD to pass through may be formed in the bottom 3.
