Description

  According to the present invention, various kinds of drinking water such as mineral water stored in a container are stored in a tank, and then the stored drinking water can be appropriately supplied by heating at room temperature or cold temperature, or by heating the stored drinking water. The present invention relates to a drinking water container used for a drinking water server.

  As a drinking water server S for supplying various kinds of drinking water such as mineral water as needed to a cup, a plastic bottle or the like, there is, for example, one shown in FIG.

  In this drinking water server S, a drinking water container T containing drinking water w in a container 1 is detachably attached to a water conduit 11 extending upward from a water storage tank 10. When the drinking water container T is attached, the drinking water w in the container 1 flows into the water storage tank 10 through the water conduit 11 due to its own weight, and is stored in the water storage tank 10.

  The water supply pipe 18 drawn out from the water storage tank 10 is provided with a supply valve 17 that can be freely opened and closed. If the supply valve 17 is opened, the drinking water w in the water storage tank 10 can be appropriately supplied to the outside. When the supply valve 17 is closed, the supply is stopped.

  The drinking water container T is supplied to the market in a state where the drinking water w in a state of being sterilized in advance is sealed in the container 1 in units of about 20 liters and sealed, for example. It is.

  Further, the container 1 is formed of a hard resin, and its shape is maintained even when the drinking water w inside is reduced, and a soft resin, that is, a flexible material is formed. There is an airless type in which when the internal drinking water w decreases, the internal volume is elastically deformed and the internal volume shrinks accordingly. In the latter case, since the air a does not enter the container 1, it is more hygienic.

  The drinking water server S corresponds to the drinking water container T using the former hard container 1 and the one corresponding to the drinking water container T using the latter soft container 1.

  The operation of the drinking water server S corresponding to the soft container 1 will be described. The drinking water w in the container 1 attached as shown in FIG. 15 (a) flows down into the water storage tank 10 and enters the container 1 When the drinking water w decreases, the container 1 shrinks and deforms, and air does not enter the container 1 (see FIG. 15B). Reference numeral 15 in the figure indicates a vent hole, and reference numeral 16 indicates a filter provided in the vent hole 15.

A float valve 14 provided at the lower end of the water conduit 11 opens and closes the lower end opening of the water conduit 11 as the water level in the water storage tank 10 fluctuates.
For this reason, the flow of water from the container 1 to the water storage tank 10 is caused by the float valve 14 closing the lower end opening of the water conduit 11 when the water level in the water storage tank 10 rises and reaches a predetermined position. It stops automatically (see FIG. 15C).

  Moreover, if the water level in the water storage tank 10 falls by supply of the drinking water w from the water pipe 18, the float valve 14 will open the lower end opening of the water conduit 11, and the drinking water w in the container 1 will store water. It flows down into the tank 10 and its water level is maintained (see FIG. 15 (d)).

  In general, a cooling device is provided in the water storage tank 10 to cool the drinking water w in the water storage tank 10 and supply it as cold water, or by providing a heating device, There is also a drinking water server S that can be supplied.

  There is also a drinking water container in which the container 1 is accommodated in a cardboard or resin storage case, and the container 1 is attached to the drinking water server S together with the storage case.

  When a force is applied from the outside when the container 1 formed of a flexible material is held in a hand, the portion to which the force is applied is deformed so as to be recessed. For this reason, when the connection part 2 which the container 1 opened with respect to the water conduit 11 is connected, force is not often transmitted with respect to the container 1 well. Moreover, since the position of the connection portion 2 tends to escape from the water conduit 11 due to the deformation of the container 1, it is often not easy to attach the drinking water server S.

  In this regard, as described above, if the container 1 is mounted in the drinking water server S while being accommodated in the storage case, the internal container 1 is not deformed even if the storage case is gripped from the outside. Therefore, if only the connecting portion is taken out from the opening provided in the storage case and is fixed to the storage case with a separate reinforcing member, the connection of the container 1 to the water conduit 11 is easy, and the container 1 after the mounting is also provided. Is held in the storage case and is stably supported with respect to the drinking water server S (see, for example, Patent Documents 1 and 2).

Japanese Patent Laid-Open No. 9-226832 JP 2010-126170 A

  However, in the container 1 formed of a soft material that can shrink with a decrease in the internal drinking water w, that is, a sheet or film made of a flexible material (hereinafter referred to as “sheet-like material”), Drinking water w that does not fall into the water storage tank 10 through the water conduit 11 to the end, so-called residual water, may be generated in the container 1.

  What is shown in FIG. 16 is an example of the container 1 before injecting the drinking water w into the inside, and FIGS. 14 (a) and 14 (c) show the container 1 after injecting the drinking water w into the inside. It is an example.

  When the above-mentioned remaining water is low in the drinking water w in the container 1, the material of the container 1 is changed from the state shown in FIG. 14A to the state shown in FIG. It is generated by partially bending, bending, or wrinkling from the state shown in FIG. 14 (c) to the state shown in FIG. 14 (d). That is, a concave portion (hereinafter referred to as “reservoir portion A”) is generated by the bending, bending, and wrinkling, and the drinking water w is retained in the reservoir portion A. When the drinking water w stays in the pool portion A, the staying drinking water w is not guided to the connecting portion 2 below, and thus does not flow to the water conduit 11 until the end.

For example, as described in Patent Documents 1 and 2, the remaining water is stored in a container case made of cardboard or resin, and the container 1 is mounted on the drinking water server S together with the container case. The same occurs in the drinking water container.
This is because even if the container 1 is housed in the storage case, the material of the container 1 is partially bent, curved, or wrinkled, so that the concave reservoir A is generated. .

  Then, this invention makes it a subject to suppress that residual water generate | occur | produces in a container.

  The biggest cause of the above problems is that when the container is deformed from a full condition to an empty condition where drainage is complete, the shrinkage of the container causes the container material to bend, bend, or wrinkle in an unintended direction. It depends. This is because the material of the container has plasticity but does not have elasticity.For example, if the surface area of the container is shrunk as the volume changes, such as a rubber balloon, Such a problem does not occur.

  In an airless type container made of a flexible material, the internal volume changes greatly between full and empty conditions, but the surface area of the container does not change. Along with this, the container extends in the vertical direction or the horizontal direction. However, since the space in the storage case that contains the container does not change, the container extends in the vertical or horizontal direction as the container is deformed from the full water state to the empty state, and the material of the container is increased by the extension. It bends and curves in various places, and becomes a ridge, and the pool part A is produced.

  In order to solve the above problems, the present invention controls the contraction change by giving a certain restriction to the contraction of the container so that the container (the empty container) is accommodated in the storage case. The shape and packaging form for this purpose are used. That is, a hanging piece is provided in the drinking water container, the container is fixed in the storage case through the hanging piece, and conditions are given to the deformation of the container.

  The specific configuration is used in the drinking water server to supply drinking water to the water storage tank of the drinking water server, and is connected to a main body part that contains the drinking water and a water conduit that leads to the water storage tank. A container having a container, and a storage case for storing the container, and with the connection part of the container facing downward, the tip of the water conduit is inserted into the connection part. Drinking water flows down into the water storage tank through the water conduit, and the container is formed of a flexible material so that it shrinks and deforms when the drinking water inside decreases, In the state where the connection portion is faced downward, a hanging piece that extends upward or laterally from the outer surface of the main body portion and has a locking portion at the tip thereof is provided, and a fixing member provided in the case includes the locking portion To lock on Ri, the vessel was drinking water containing assembly characterized in that it is supported by hanging fixed to the casing through the hanging pieces.

Thus, the container has a hollow main body portion in which drinking water is accommodated, and a connection portion that functions as an inlet and an outlet for drinking water, and the container has an opening portion on the opening side in the storage case. It is stored so that it faces. When this drinking water container is attached to the drinking water server, the storage case is turned upside down and the connecting portion of the container faces downward. For this reason, when the drinking water in a container becomes low, drinking water collects in the lower part including the connection part vicinity.
At this time, the material (flexible material) constituting the main body of the container is a beverage between the lower part of the main body where the drinking water is collected and the locking portion of the hanging piece. Pulled by the weight of water. By this pulling, the material (a material having flexibility) is in a tensioned state, making it difficult to form a reservoir and preventing the generation of residual water.

The size of the storage case refers to the horizontal direction of the empty container, that is, the direction connecting the connecting portion and the locking portion of the container in relation to the size of the empty container that does not store drinking water. It is desirable to secure an “inner” that is equal to or larger than the total length of the storage case on the lower side and the side that rises from the lower side of the storage case in a use state (a state in which the drinking water storage device is attached to the server). That is, in the storage case in the use state, a horizontal direction and a vertical direction connecting a portion that fixes a container connection portion at a lower portion of the storage case and a portion where the storage case locks the locking portion of the container. It is desirable that the total of the “inner” is longer than the length in the direction connecting the connecting portion and the locking portion of the container in the empty container.
In this way, the storage case supports the container so as to be suspended from above via a locking portion provided on the container, and the lowermost connection portion is fixed to the storage case, so that the container is configured. The material to be pulled is pulled downward by its own weight of drinking water. As drinking water decreases, the container shrinks so that it sticks to the lower part and both sides extending from the lower part, and its full length is secured between the connecting part and the locking part, so it is partially bent or curved Or the generation of residual water can be suppressed.

  Here, the remaining water is likely to be generated when the amount of drinking water in the container is almost reduced. For this reason, for example, when the hanging piece extends upward from the middle in the vertical direction of the main body in the state in which the connecting portion is directed downward, after the drinking water surface reaches the middle in the vertical direction. The generation of the reservoir until drinking water is completely eliminated can be effectively suppressed. This is because the tensile force acts from the locking portion of the hanging piece to the root portion, and from the root portion to the lower end portion of the container in which drinking water is accumulated.

This hanging piece is desirably provided in four directions or two directions starting from the lowermost connecting portion in the use state. When two suspension pieces are provided in two directions, that is, two suspension pieces, it is desirable that the two suspension pieces are provided to face both sides with the main body portion interposed therebetween. Further, it is more desirable to arrange them symmetrically across the connecting portion. This is because the tensile force on the container material due to the weight of the drinking water acts on the entire main body in a well-balanced manner.
Further, when three, four, or more hanging pieces are provided, it is desirable that the hanging pieces are provided without being biased in a certain direction along the periphery of the main body. Further, it is desirable that these hanging pieces are arranged in a balanced manner in a plane view equally divided around the connection portion with the connection portion as the center.

  Moreover, a container can also be set as the following structures. That is, the main body portion is configured such that a plurality of sheet-like objects are joined to each other at a joint portion, and a space capable of containing drinking water is formed inside the joint portion, The suspension piece is provided at a central portion of one sheet-like material of the sheet-like material, and the hanging piece is outside from the joint portion between the one sheet-like material provided with the connection portion and the other sheet-like material. It is the structure extended to the direction side or upward.

  In this way, if the hanging piece extends from the joint portion between the sheet-like materials constituting the main body portion, the joint portion does not intervene in the lower portion of the container where the occurrence of residual water is likely to be a problem. When the is pulled, it is easy to eliminate bending, bending, and wrinkles.

  In this configuration, if the one sheet-like object provided with the connecting portion and the hanging piece are formed of a single continuous sheet-like object, they are located on the connecting portion side. Since the sheet-like object and the suspended piece can be formed of the same material, the number of parts at the time of manufacture is reduced, and the manufacture is facilitated.

In each of these configurations, various configurations may be adopted for the locking structure of the fixing member provided in the storage case and the locking portion provided in the hanging piece. It is a hole formed in the hanging piece, and the fixing member has a locking projection, and the locking projection is inserted into the hole so that the fixing member is locked to the locking portion. can do.
In other words, the locking protrusion of the fixing member enters the hole of the hanging piece from the lower side to the upper side (with the connecting portion of the container facing downward), so that both can be locked.

  Further, as another locking structure, for example, a structure in which a fixing member provided in the storage case and a locking part provided in the hanging piece are joined to each other by a joining means such as a stapler, a pin, or an adhesive, or A structure or the like in which the locking portion of the hanging piece is firmly sandwiched between the inner surface of the storage case and the fixing member can be considered.

  Moreover, the following structures are employable as a specific structure of a fixing member.

  For example, the storage case includes a concave case body having an opening portion on one side and a bottom portion on the other side, and a folded piece continuously provided at an edge of the opening portion, and the connection portion of the container includes the opening portion. The fixing member is housed in the case body so as to face the side, and the fixing member is the folded piece folded into the case body toward the bottom.

  According to another configuration, the storage case includes a concave case body having an opening on one side and a bottom on the other side, a lid continuous to the edge of the opening, and an edge of the lid. And the container is housed in the case body so that the connection portion faces the opening, and the fixing member is folded into the case body toward the bottom. It is the structure which is the said folding piece.

  Furthermore, as another configuration, the storage case includes a concave case body having an opening on one side and a bottom on the other side, and an auxiliary member formed separately from the case body and inserted into the case body. And the container is housed in the case main body so that the connection portion faces the opening, and the auxiliary member holds the lid that covers the opening and the lid rises from the lid toward the bottom And the auxiliary member is inserted into the case body, whereby the holding portion is locked to the locking portion, and the holding portion is used as the fixing member.

  Further, in each of these configurations, the connecting portion of the container has a cylindrical opening protruding from the main body, and a reinforcing cylinder is fitted on the outer periphery of the cylindrical opening, or integrated. In the state where the cap is attached to the reinforcing cylinder and the container is closed, the reinforcing cylinder has a flange portion protruding to the outer diameter side, and the connecting portion is pulled out of the storage case. A configuration in which the connecting portion is fixed to the storage case by inserting a reinforcing member between the flange portion and the outer surface of the storage case can be employed.

  According to this configuration, since the connection portion can be firmly fixed to the storage case, when the drinking water in the container is reduced, the lower portion of the main body portion where the drinking water is collected, the locking portion of the hanging piece, The tensile force due to the dead weight of the drinking water can be effectively applied.

  Since this invention provided the hanging piece in the container which accommodated the drinking water, and suspended and supported the container in the storage case via the hanging piece, it suppresses generation | occurrence | production of residual water in a container. Can do.

Plan view of container of conventional example (state before containing drinking water)

  An embodiment of the present invention will be described with reference to FIGS. In the drinking water container T of this embodiment, the container 1 formed of a soft resin, which is a flexible material shown in FIG. 2, is placed in a storage case 20 formed of cardboard as shown in FIG. Contained and configured.

  The basic configuration of the drinking water server S using the drinking water container T is the same as that of the conventional example. In order to supply the drinking water w to the water storage tank 10 of the drinking water server S, the drinking water server S rises from the water storage tank 10. The drinking water container T can be attached to and detached from the water guide pipe 11.

  The container 1 has a bag-shaped main body 3 capable of forming a space capable of containing drinking water w therein, and a connection portion 2 connectable to the water conduit 11 of the drinking water server S. The connecting portion 2 is formed at the tip of a cylindrical protruding portion 4 protruding from the main body portion 3.

  The container 1 is in a flat state before being filled with drinking water w. 2 (a) and 2 (b) show a state before the container 1 is filled with drinking water w, and a plurality of resin sheet-like objects 3b, 3c, 3d, 3d are joined to each other at the joint 3a. ing. Drinking water w can be accommodated inside the joint 3a. FIG. 2C is a perspective view of the state after the container 1 is filled with the drinking water w through the connection portion 2.

  The container 1 of this embodiment is formed of an aluminum vapor deposition film or a nylon material (polyamide resin), and the joining portion 3a is formed by welding. However, the material of the container 1 is not limited to the aluminum vapor-deposited film or the nylon material, and other materials may be those made of a flexible material (soft plastic or the like). That is, when the drinking water w in the container 1 decreases, it is effective in the drinking water server S using the drinking water container T of the type in which the container 1 contracts and deforms to prevent air from entering inside. is there.

In addition, after accommodating the drinking water w in the container 1, the opening of the connection portion 2 is closed with the cap 40. As an example of the cap 40, for example, the one shown in FIG. 3 can be adopted.
That is, the connecting portion 2 of the container 1 has a cylindrical opening protruding from the main body 3, and the reinforcing cylinder 43 is fitted on the outer periphery of the cylindrical opening, and the cap 40 is attached to the reinforcing cylinder 43. Attached and the container 1 is closed. The cap 40 is attached so as to close the connection portion 2 after the tip of the protruding cylindrical opening portion is folded back to the outer periphery of the reinforcing tube 43. A through hole 41 is provided in the center of the cap 40, and a stopper 42 is provided that is pushed by the tip of the water guide tube 11 and removed when the water guide tube 11 is inserted. In the drawings other than FIG. 3, illustration of the through hole 41 and the like of the cap 40 is omitted. Further, the reinforcing cylinder 43 can be welded to the opening of the container 1.

  As shown in FIGS. 2 (a) to 2 (c), the container 1 has one sheet-like material 3b, another sheet-like material 3c facing it, and the edge between both sheet-like materials 3b and 3c. It is comprised with the other sheet-like objects 3d and 3d which are closing the side so that it may tie, and they are joined by the said junction part 3a, and are closed in bag shape.

  The container 1 is provided with a hanging piece 30. In this embodiment, the suspension piece 30 is provided opposite to both sides with the main body portion 3 interposed therebetween, and extends from the joint portion 3a.

The hanging piece 30 extends downward from the joint portion 3a in the middle of the vertical direction of the side surface of the main body portion 3 with the connection portion 2 shown in FIG. A portion 31 is provided. In this embodiment, the locking portion 31 is a hole 31 a formed so as to penetrate the sheet-like object of the hanging piece 30.
In the state of use described later, the container 1 is used with the connecting portion 2 facing downward. In this state of use, the hanging piece 30 is joined to the middle of the side surface of the main body portion 3 in the vertical direction. It extends from the part 3a and has a positional relationship having a locking part 31 in the upper part (see FIG. 5 (f) described later).

Moreover, the connection part 2 is provided in the center part of one sheet-like thing 3b shown to Fig.2 (a)-(c) among the said sheet-like thing 3b, 3c, 3d, 3d which comprises the container 1. As shown in FIG. Yes. The hanging piece 30 is formed of a single sheet-like material continuous with the one-sheet-like material 3b provided with the connecting portion 2.
That is, the one sheet-like material 3b and the hanging piece 30 located below (in the connecting portion 2 side) in the use state are formed of a single continuous material, and the number of parts at the time of manufacture is reduced. The production is easier.

  The container 1 is transported, stored, etc. in the state of being accommodated in the storage case 20 shown in FIG. 1, and further, when the container 1 is attached to the drinking water server S and used, the container 1 is used while being accommodated in the storage case 20. It is like that.

  In this embodiment, the storage case 20 is made of corrugated cardboard. However, for example, a storage case 20 formed of another material such as a plastic one may be used.

  The storage case 20 includes a case main body 22 having a concave storage portion 22c having an opening 22a on one side and a bottom 22b on the other side, and an auxiliary member formed separately from the case main body 22 and inserted into the case main body 22. 29.

  The case body 22 has side walls 22d that rise from the periphery of the bottom portion 22b, which has a rectangular shape, and includes a lid 24 that closes the opening 22a at the upper edge of the side walls 22d.

  The auxiliary member 29 includes a lid portion 25 that covers the opening 22 a of the case body 22, and a pair of holding portions 26 that rise from both end edges of the lid portion 25 toward the bottom portion 22 b of the case body 22. It is a member having a U-shaped cross section. Locking protrusions 21 a and 21 a are provided at the distal ends of the holding portions 26, and the holding portions 26 function as the fixing members 21 that support the container 1 through the hanging pieces 30.

  When the container 1 is stored in the storage case 20, first, the container 1 is stored in the storage portion 22 c of the storage case 20 as shown in FIG. At this time, the connecting portion 2 is directed toward the opening 22a.

  At this time, the drinking water w may be accommodated in the container 1 in advance and the connecting portion 2 may be closed with the cap 40, or the empty (empty) where the drinking water w is not accommodated. After the container 1 in the state is accommodated in the accommodating portion 22c, the drinking water w may be filled and the cap 40 may be attached.

  Thereafter, as shown in FIG. 2B and FIGS. 4A and 4B, the auxiliary member 29 is inserted into the case main body 22. At this time, the tip of the holding portion 26 is addressed to the root portion of the hanging piece 30 (near the joint portion 3a).

When the auxiliary member 29 is pushed in from this state, the tip of the holding portion 26 pushes down the suspension piece 30 as shown in FIGS.
At this time, the part where the tip of the holding part 26 touches the suspension piece 30 gradually moves from the root part near the joint part 3a to the tip side.

  When the auxiliary member 29 is further pushed in and the auxiliary member 29 is completely inserted into the storage portion 22c, the tip of the holding portion 26 is engaged as shown in FIGS. 2 (c), 4 (e), and (f). It reaches the stop 31. Then, the locking projection 21 a provided at the tip of the holding portion 26 enters the hole 31 a of the locking portion 31. In this state, the holding portion 26 as the fixing member 21 is locked to the locking portion 31.

  At this time, the locking projection 21a that has passed through the hole 31a contacts the bottom 22b of the storage case 20, so that the locking between the locking projection 21a and the locking portion 31 is not easily released thereafter. .

  Finally, the lid 24 of the storage case 20 is closed and sealed with tape or the like, and the drinking water container T is completed.

  The usage method of this drinking water container T is demonstrated. FIG. 5A shows a state before the storage case 20 of the drinking water container T is opened. From this state, first, as shown in FIG. 5B, the opening 27 is opened. The opening 27 can be opened by cutting the opening piece 27b along the cut line 27a provided in the lid 24.

  Next, as shown in FIG. 5C, the connecting portion 2 of the container 1 is pulled out through the opening 27. Then, the reinforcing member 28 is attached on the lid 24.

  As shown in FIG. 5C, the reinforcing member 28 is formed of a plate-like member, and is provided with a notch 28a having an opening 28b at one end edge thereof. The notch 28a extends from the opening 28b to the one end edge in the shape of a long hole with a certain width toward the center of the plate surface of the reinforcing member 28. The reinforcing member 28 may be made of resin or cardboard.

Further, the reinforcing cylinder 43 fitted around the protruding portion 4 of the container 1 is provided with a flange portion 44 that protrudes to the outer diameter side, and a connecting point to the main body portion 3 is provided below the flange portion 44. A neck portion 45 that expands in a trumpet shape is provided (see FIG. 3).
The small diameter portion between the neck 45 and the flange 44 is inserted into the notch 28a from the opening 28b, and the reinforcing member 28 is slid laterally in the direction of the arrow shown in FIG.

  As shown in FIG. 5D, the small diameter portion between the neck portion 45 and the flange portion 44 reaches the inner portion of the notch 28a, and the attachment of the reinforcing member 28 is finished. At this time, the width of the notch 28a is smaller than the outer diameter of the neck portion 45 and the flange portion 44, and is the same as the outer diameter of the small diameter portion between the neck portion 45 and the flange portion 44, or Since they are substantially the same, the reinforcing member 28 is prevented from coming off by friction between the outer periphery of the reinforcing cylinder 43 and the inner edge of the notch 28a. Further, since the width of the notch 28a is narrower than the outer diameter of the neck portion 45 and the flange portion 44, the connection portion 2 of the container 1 may enter the storage case 20, or the connection portion 2 may be opened excessively. Protruding from 27 is prevented.

  That is, in a state where the connection portion 2 is pulled out of the storage case 20 through the opening 27, the reinforcing member 28 is inserted between the flange portion 44 and the outer surface of the storage case 20, thereby connecting the connection portion 2 to the storage case 20. It is fixed to.

  When the drinking water container T is attached to the drinking water server S, as shown in FIG. 5 (f), the storage case 20 is turned upside down so that the connecting portion 2 of the container 1 faces downward.

  And the front-end | tip of the water conduit 11 of the drinking water server S is inserted in the through-hole 41 (refer FIG. 3) of the cap 40, and the connection part 2 of the container 1 and the water conduit 11 communicate, and the inside of the container 1 Drinking water w flows down into the water storage tank 10 through the water conduit 11. At this time, the storage case 20 can be held so as not to move by an appropriate member provided in the drinking water server S (see, for example, the concave portion 12 and the receiving portion 12a in FIG. 10).

When the storage case 20 is turned upside down, as shown in FIG. 6A, the container 1 is supported by being suspended from the storage case 20 via the suspension piece 30 with the connection portion 2 facing downward. It becomes a state. In FIG. 6, the case main body 22 and the like of the storage case 20 are not shown.
That is, the hanging piece 30 extends upward from the outer surface of the main body portion 3 and has a locking portion 31 at the upper portion thereof. The fixing member 21 including the holding portion 26 is locked to the locking portion 31. Because it is. The fixing member 21 supports the container 1 as indicated by an arrow a in FIG.

Next, when the drinking water w in the water storage tank 10 of the drinking water server S is supplied to the outside, the drinking water w in the container 1 flows down through the water conduit 11 accordingly, and the drinking water w is stored in the water storage tank 10. Is replenished.
At this time, since the container 1 is formed of a flexible material, the container 1 is contracted and deformed when the internal drinking water w decreases.

When the container 1 drinking water w decreases, for example, when the state shown in FIG. 6 (b) is reached, the sheet-like material constituting the main body 3 of the container 1 is the main body where the drinking water w is gathered. 3 and the base part of the suspension piece 30 (near the joint part 3a), as shown by the arrow b in the figure, is pulled by its own weight of the drinking water w. In addition, a tensile force is generated on the lower surface of the main body 3 as indicated by an arrow c in the drawing.
By this tension, the sheet-like material is in a tensioned state, making it difficult for the conventional reservoir A (see FIG. 9) to occur, and preventing the generation of residual water.

  In addition, as shown in FIG.6 (c), this effect can be continued to the state just before the drinking water w in the container 1 is completely lost.

  At this time, since the connecting portion 2 of the container 1 can be firmly fixed to the storage case 20 by using the reinforcing member 28, the drinking water w is gathered when the drinking water w in the container 1 decreases. The tensile force by the dead weight of the drinking water w between the lower part of the main-body part 3 and the latching | locking part 31 of the hanging piece 30 can be made to act effectively.

  The size of the storage case 20 is in the lateral direction of the empty container 1, that is, with the connection portion 2 of the container 1 in relation to the size of the empty container 1 in which the drinking water w is not stored. Storage of “inner”, which is equal to or larger than twice the length in the direction connecting the portion 31 (see L3 in FIG. 2), in a used state (a state in which a drinking water container is attached to a server) It is desirable to secure the case 20 on the lower side and the side surface rising from the lower side.

  That is, in the storage case 20 in the use state, between the portion that fixes the connection portion 2 of the container 1 at the lower portion of the storage case 20 and the portion that the storage case 20 locks the locking portion 31 of the container 1. The horizontal “inner” (see L1 in FIGS. 5 (e) and 6 (c)) and the vertical “inner” (see L2 in FIGS. 5 (e) and 6 (c)) are It is desirable that the empty container 1 is longer than the length in the direction connecting the connecting portion 2 and the locking portion 31 of the container 1 (see L3 in FIGS. 2A and 2B). The same applies to the relationship between the portion for fixing the connecting portion 2 of the container 1 and the locking portion 31 on the opposite side.

  Note that the overall length in the width direction of the empty container 1 (see L4 in FIG. 2) is equal to or smaller than the “inner” in the width direction of the storage case 20 (see L5 in FIG. 5E). ing.

  Further, in this embodiment, the hanging piece 30 extends upward from the joint portion 3a between the one sheet-like object 3b provided with the connecting portion 2 and the other sheet-like objects 3c, 3d, 3d. The pulling of the arrows b and c due to the dead weight of the drinking water w acts only on one continuous sheet. For this reason, generation | occurrence | production of the accumulation part A can be avoided further reliably.

  This is because when the drinking water w is running low, if the drinking water w is touching the joint 3a, the reservoir A is likely to occur. When the container 1 is in use, it is desirable that the joint portion 3a does not exist in the lower portion of the container 1, and the joint portion 3a is desirably located in the middle of the main body portion 3 in the vertical direction or more. .

  In addition, since the one sheet-like object 3b provided with the connecting portion 2 and the hanging piece 30 are formed by a single continuous sheet-like object, in the use state, the lower side (the connecting portion 2 side) The one sheet-like material 3b and the suspended piece 30 located at the same position are formed of a single continuous material, and the tensile force on the material of the container 1 is between the locking portion 31 and the connecting portion 2. The force is transmitted directly, which is more effective in preventing the accumulation portion A from being generated.

  In addition, as another embodiment regarding the storage case 20 and the fixing member 21, the configuration shown in FIGS. 7 and 8 can be employed.

  The storage case 20 shown in FIG. 7 and FIG. 8 has a folding piece 23 provided continuously to a lid 24 that closes an opening 22a, instead of using an auxiliary member 29 having a holding portion 26 that functions as a fixing member 21. Thus, the folded piece 23 is made to function as the fixing member 21. In addition, since the structure of the other part of the container 1 is the same as that of the above-mentioned embodiment, description is abbreviate | omitted.

  As shown in FIGS. 7 (a) and 8 (a), the case main body 22 has four side walls 22d that rise from the periphery of the bottom 22b, which has a rectangular shape.

  In this embodiment, the folding pieces 23 are connected to the edges 24a, 24a on both sides in the width direction of the lid 24, respectively.

  The procedure for housing the container 1 in the storage case 20 will be described. The container 1 is stored in the storage portion 22 c of the storage case 20. At this time, the connecting portion 2 is directed toward the opening 22a.

  Thereafter, the lid 24 is closed from the state shown in FIG. 7A or FIG. 8A to the state shown in FIG. 7B or FIG. 8B. That is, it is rotated in the closing direction. At this time, the folding piece 23 is inserted into the case main body 22 along the side wall portion 22d, and the tip of the folding piece 23 is directed to the root portion (near the joint portion 3a) of the hanging piece 30.

When the lid 24 is further closed from this state, the tip of the folding piece 23 pushes down the hanging piece 30.
At this time, the part where the tip of the holding part 26 touches the suspension piece 30 gradually moves from the root part near the joint part 3a to the tip side.

  Further, when the lid body 24 is rotated in the closing direction and the folding piece 23 is completely inserted into the storage portion 22c, the folding piece 23 is obtained as shown in FIGS. 7C, 8E, and 8F. The tip of the lead reaches the locking portion 31. Then, the locking projection 21 a provided at the tip of the folding piece 23 enters the hole 31 a of the locking part 31. In this state, the folding piece 23 as the fixing member 21 is locked to the locking portion 31. The fixing member 21 is a folded piece 23 that is folded into the case main body 22 toward the bottom 22b.

  At this time, the locking projection 21a that has passed through the hole 31a contacts the bottom 22b of the storage case 20, so that the locking between the locking projection 21a and the locking portion 31 is not easily released thereafter. .

  Finally, the lid 24 of the storage case 20 is closed and sealed with tape or the like, and the drinking water container T is completed.

  In yet another embodiment, the folding piece 23 as the fixing member 21 is not connected to the edge of the lid 24, but is connected to the periphery of the opening 22a, that is, the upper edge of the side wall 22d. The provided mode is also conceivable.

  The folding piece 23 as the fixing member 21 is folded into the case body 22 from the upper edge of the side wall portion 22d toward the bottom portion 22b in the storage portion 22c, and the folding piece 23 is locked to the locking portion 31 of the container 1. To do. The lid 24 that closes the opening 22a can be connected to the upper edge of the side wall 22d that is different from the side wall 22d in which the folded piece 23 is connected.

  At this time, the locking protrusion 21a and the hole 31a of the above-described embodiment can be used for locking the folding piece 23 and the locking portion 31.

  In any of the embodiments, the locking structure of the holding portion 26 or the folding piece 23 as the fixing member 21 and the locking portion 31 of the hanging piece 30 is the locking protrusion 21a of the above-described embodiment. The configuration of the holes 31a is not limited. As another locking structure, for example, a structure in which the fixing member 21 provided in the storage case 20 and the locking portion 31 provided in the hanging piece 30 are joined to each other by a joining means such as a stapler, a pin, or an adhesive. Alternatively, a structure in which the locking portion 31 of the hanging piece 30 is firmly sandwiched and fixed between the inner surface of the storage case 20 and the fixing member 21 can be considered.

  When the fixing member 21 provided in the storage case 20 and the locking portion 31 provided in the hanging piece 30 are joined by a joining means such as a stapler, a pin, or an adhesive, the opening 22a side enters the storage portion 22c. You may insert a hand or a jig and perform the joining operation. If the folded piece or the bottom lid for closing the bottom portion 22b of the storage portion 22c is not closed yet, the inside of the storage portion 22c from the bottom portion 22b side. Hands and jigs can be put in and the joining work can be performed.
