A liquid supply method.

[0015] Next, an example of an embodiment of a liquid supplying device according to the present disclosure will be described with reference to the drawings. Note that the present disclosure is not limited to the following embodiment. In the following drawings, the same parts are denoted by the same reference numerals.

[0016] 1 and 2 show an example of the liquid supplying device of the present disclosure. FIG. 1 is a perspective view of the liquid supplying device of this example, and FIG. 2 is a cross-sectional view seen in the II direction in FIG. 1. As shown in both figures, the liquid supplying device 1 of this example has as its main components a cylindrical storage section 11, a tubular liquid intake section 14, a connecting tube section 143, and a liquid injection section 12. The cylindrical storage section 11 has a bottom section 112 disposed inside a cylindrical body 111, and the upper part of the cylindrical body 111 is opened to form an opening. The opening can be closed with a lid or the like. The internal space of the cylindrical body 111 forms a storage section 113 capable of storing a bag body 2, and a bag body filled with liquid can be inserted into the storage section 113 from the opening. A mounting hole is formed in a part of the bottom section 112 of the cylindrical storage section 11. A needle-shaped pointed head 141 is formed at one end (upper end in the figure) of the tubular liquid intake part 14, and a liquid intake hole 142 is formed in the tube wall of the tubular liquid intake part 14, and the liquid intake hole 142 communicates with the inside of the tube of the tubular liquid intake part 14. The tubular liquid intake part 14 is attached to the mounting hole with the pointed head 141 protruding upward inside the cylindrical storage part 11 (storage part 113). One end of the connecting tube part 143 is connected to the other end (lower end in the figure) of the tubular liquid intake part 14, and the two are in communication. The liquid injecting part 12 includes a liquid injecting port, and the other end of the connecting tube part 143 is connected to the liquid injecting part 12, and the liquid injecting port and the inside of the tube of the connecting tube part 143 are in communication. The liquid injecting part 12 is provided with a cock part 13 as an opening and closing mechanism. Cock portion 13 has a structure in which a lever handle 131 and a stopper are connected, and a communication hole 132 is formed at the bottom of the stopper. In Figures 1 and 2, communication between the liquid inlet and the inside of the pipe of connecting pipe portion 143 is closed by cock portion 13. Note that the form of the opening and closing mechanism is not limited to this example, and may be, for example, a form in which the stopper is closed by a rotating screw type stopper.

[0017] 1, the bag body 2 is inserted through the opening of the cylindrical storage section 11, and is stored in the storage section 113. The inner diameter W1 of at least a part of the storage section 113 (inside) of the cylindrical storage section 11 is set to be equal to or smaller than the width direction length of the bag body 2 in the insertion direction.

[0018] FIG. 3 shows an example of the bag of the present disclosure. FIG. 3(A) is a perspective view of the bag of the present embodiment, FIG. 3(B) is a front view or a back view of the bag of the present embodiment, FIG. 3(C) is a side view of the bag of the present embodiment, and FIG. 3(D) is a top view or a bottom view of the bag of the present embodiment. As shown in FIG. 3(A) to (D), the overall shape of the bag 2 is a so-called pillow shape, the front shape and the back shape are rectangular (rectangular), and the side shape, the top shape and the bottom shape are a pair of arcs facing each other in opposite directions (leaf shape). The bag 2 has a structure in which, for example, the upper edge and the lower (bottom) edge of a pair of rectangular films are bonded, and the side of the leaf shape is connected to both side edges of the pair of rectangular films via a film. In FIG. 3, if the vertical direction of h is the insertion direction into the cylindrical storage section 113, W2 is the width direction length with respect to the insertion direction. Conversely, in Fig. 3, if the vertical direction of W2 is the insertion direction into the cylindrical storage section 113, then h is the widthwise length with respect to the insertion direction. In other words, when the front and back shapes of the bag body 2 are rectangular, the widthwise length of the bag body in the insertion direction is the length of a side of the rectangular shape that extends perpendicularly to the insertion direction. The shape of the bag body is not limited to the shape in Fig. 3, and may be, for example, spherical or elliptical.

[0019] An example that does not correspond to the liquid supplying device of the present disclosure is shown in Fig. 4. In Fig. 4, the inner diameter W1 of at least a part of the storage section (inside) 113 of the cylindrical storage section is not set to be equal to or less than the widthwise length W2 of the bag body 2 relative to the insertion direction, and in other words, the widthwise length W2 of the bag body 2 is smaller than the inner diameter W1 of the storage section 113 of the cylindrical storage section. In this case, as shown in Fig. 4, since the bag body 2 has play space within the storage section 113, even if it comes into contact with the needle-shaped pointed head of the liquid collection section 14, the bag body 2 can deform and escape puncturing, making puncturing difficult.

[0020] An example of the use of the liquid supplying device of this embodiment is shown in Fig. 5. In Fig. 5, the inner diameter W1 of at least a part of the storage section (inside) 113 of the cylindrical storage section is set to be equal to or less than the widthwise length W2 of the bag body 2 relative to the insertion direction, and conversely, the widthwise length W2 of the bag body 2 is greater than the inner diameter W1 of the storage section 113 of the cylindrical storage section. In this case, as shown in Fig. 5, the bag body 2 has no play space in the storage section 113, and the surface of the bag body 2 comes into contact with the inner wall surface of the storage section 113 during insertion, so that the lower part of the bag body 2 is pulled laterally and put into a taut state, and even if the bag body 2 comes into contact with the needle-shaped pointed head of the liquid collection section 14, the bag body 2 does not deform and escape from the puncture, making the puncture easy and reliable.

[0021] FIG. 6 shows an example of the tubular liquid collection section 14. The tubular liquid collection section 14 shown in FIG. 6(A) has a needle-shaped pointed head 141, and is an example in which a plurality of liquid collection holes 142 are formed in the tube wall of the tubular liquid collection section 14. As shown by the arrows in FIG. 6(A), the liquid filled inside the bag body 2 is collected into the tube from the liquid collection holes 142. The tubular liquid collection section 14 shown in FIG. 6(B) has a shape in which the tip of the tube is cut off obliquely (tapered), and the liquid collection hole 142 is formed in the pointed head 141. As shown by the arrows in FIG. 6(B), the liquid filled inside the bag body 2 is collected into the tube from the liquid collection hole 142 of the pointed head 141. Note that in the present disclosure, the tubular liquid collection section 14 may be one or more. Furthermore, in the present disclosure, the tubular liquid collection section 14 may be in an upright (vertical) state with respect to the bottom 112 and facing upward within the storage section (inside), or may be in an inclined state with respect to the bottom 112 and facing upward within the storage section (inside).

[0022] Another example of the liquid supplying device of the present disclosure is shown in Fig. 7. In the liquid supplying device of this example, the cylindrical body of the cylindrical container has a container section (interior) 113 tapered such that the inner diameter continuously decreases from the top to the bottom. In the tapered cylindrical body, it is sufficient that the inner diameter of at least a part of the container section 113 is set to be equal to or less than the width direction length of the bag body in the insertion direction.

[0023] In the present disclosure, for example, the lower limit of the inner diameter of at least a part of the inside of the tubular storage section 11, which is set to be less than the widthwise length of the bag body in the insertion direction, is set to a size that allows the lower part of the bag body 2 to be punctured by the pointed portion 141 in the insertion direction.

[0024] In the present disclosure, the material for forming the cylindrical storage section 11 is not particularly limited, and it is possible to use, for example, a material used for a water server or the like. For example, if it is a metal, stainless steel can be used, and if it is a transparent material, transparent resin (for example, acrylic resin, etc.) and glass can be used.

[0025] In the present disclosure, the materials for forming the tubular collection section 14, the connecting pipe section 143 and the injection section 12 are not particularly limited, and for example, materials for use in ordinary water servers, etc., can be used, such as metals such as stainless steel, resins for piping, etc.

[0026] The liquid supplying apparatus 1 of the present disclosure may include at least one of a device for heating the liquid to be supplied and a device for cooling the liquid to be supplied.

[0027] There is no particular limitation on the material from which the bag body 2 of the present invention is made, and for example, a resin such as vinyl can be used.

[0028] In the present disclosure, the liquid to be supplied (the liquid filled in the bag) is not particularly limited, and examples thereof include water (natural water, etc.), soft drinks (juice, sports drinks, etc.), tea (e.g., green tea, roasted green tea, black tea, and pear tea), coffee, etc. In addition, in the present disclosure, the liquid to be supplied may be a liquid for purposes other than beverages (e.g., seasoning, industrial use, home gardening use, agricultural use, etc.).

[0029] Although the present disclosure has been described above with reference to the embodiments, the present disclosure is not limited to the above-described embodiments. Various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure.
