8 and 9 are schematic views when the pouch container 1 shown in FIG. 1 is filled with the contents. When the pouch container 1 is filled with the contents, the contents also enter the gussets at both ends. In addition, the gusset portion is folded when it is empty, but expands to the outside of the container when the contents are filled. In the pouch container 1 of FIG. 1, since the guide poles 16 and 17 are adhered to the folded parts of the gusset portions 13 and 14, the gusset portion expands and the guide pole also expands together.

When the guide poles are provided in the left and right gussets as shown in FIG. 1, the distance (width) between the guide poles provided in the left and right gussets is not particularly limited, but is based on the viscosity of the contents and the like. It can be set to a suitable distance. When the pouch container is filled with the contents, the guide pole is provided, so that the contents are subjected to pressure to be pushed out of the pouch container. Therefore, when the contents are taken out from the pouch container, for example, when the contents are sucked from the outlet, the contents can be easily sucked with a very small sucking force. When the contents start to flow out, the contents on both side edges of the pouch container first flow out. Next, the pouch container contracts due to the force of the guide pole, and a flow path through which the contents flow is formed along the guide pole on the inner surface of the pack container, and the contents flow efficiently toward the outlet. The contents are drained until the center of the pouch container is in perfect contact. As a result, almost all the contents in the pack container can be easily discharged.

When the guide poles are provided inside the both side edges of the side surface as shown in FIG. 2, the distance (width) between the left and right guide poles is not particularly limited, but is the same as or equal to the width of the side surface. It can be set larger. If the width is set larger than the width of the side surface portion, a strong pressure is applied to the left and right outside, and tension is created on the entire surface of the pouch container, so that a stronger pressure is applied to the contents to push them out. As a result, even if the content is a highly viscous liquid or a gel-like substance, it can be easily discharged. Further, as in the embodiment of FIG. 1, the pouch container contracts due to the force of the guide pole, and a flow path for the contents to flow along the guide pole on the inner surface of the pack container is created, so that the contents are efficiently directed toward the outlet. It flows well. The contents are drained until the center of the pouch container is in perfect contact. As a result, almost all the contents in the pack container can be easily discharged.

Since the pouch container of the present invention can easily drain the contents, it is useful when the contents are to be ingested quickly, for example, while driving or exercising. Further, the pouch container of the present invention is useful even for a sick person or an infant having a weak drinking ability because the contents can be easily sucked and swallowed. Further, in the pouch container of the present invention, even the contents having low fluidity can be easily discharged, so that the amount remaining in the container can be reduced.

The contents contained in the pouch container of the present invention may be a substance having fluidity or a substance that can acquire fluidity by external pressure or the like, for example, liquid, creamy and gel-like foods and drinks. It can be a seasoning, cosmetics, detergent, etc. Specifically, for example, various beverages such as water, juice and sports drinks, creamy foods such as ice cream, gel foods such as jelly and 蒟 蒻 jelly, liquid foods such as soup, liquid foods such as porridge, and liquid seasonings. , Cooking oil, miso, basic cosmetics, laundry detergent, dishwashing detergent, shampoo, body soap, hand soap and various other detergents.

The container was filled with pudding.

As a result, as shown in Table 2, 97 to 98% of the contents in the container could be discharged only by the sucking power without depending on the viscosity of the contents. In particular, when the highly viscous content was discharged, the content could be discharged with a very weak force as compared with the comparative example.

(Examples 6 to 9)
Using a suction device, the ease of sucking and drinking of the pouch container of the present invention at a suction force of 0.010 mPa was measured. As shown in FIG. 10, the ease of sucking each food or drink in the pouch container of the present invention is determined by using a suction device in which the attachment port of the pouch container, the hose, the solution recovery unit, the valve, and the suction pump are assembled in this order. It was measured. The pouch container is connected to the attachment port of the pouch container and connected to the solution recovery unit via a hose. The solution recovery unit creates a negative pressure inside the solution recovery unit by sucking it into a suction pump connected via a valve, but the suction pump sucks only air and stores the liquid at the bottom without sucking the liquid. The valve was adjusted so that the suction by the suction pump had a pressure of 0.010 mPa. In addition, the same contents were filled in the pouch container, the pouch container (without the guide pole), and the pouch container (with the guide) of the present invention of each commercially available product. Each container was attached to the attachment port of the pouch container of the suction device, and the contents were sucked by the suction pump. The contents were sucked by a suction pump until they were no longer sucked into the solution recovery section. By measuring the remaining amount after suction, the ease of suction can be compared.
