201247486 口部改變成朝橫方向部份尖起的形狀’或者是甚至在支持 座裝設握把，都可使該橫向的口部經常以穩定的方向來使 用。 本發明的第2個特徵構成爲：具備：在可供收容液體 進出的口部設有蓋部螺合用之螺紋部的液體收容體、以及 用來收納上述液體收容體的支持座’上述支持座係具有卡 止部，該卡止部係當以立姿支持著上述液體收容體時’卡 止支持著被卡止部’該被卡止部是設在比上述口部的上述 螺紋部更位於上述液體收容體的本體部側’在上述被卡止 部與上述卡止部之間’係設有阻止彼此相對旋轉的旋轉阻 止機構。 根據本發明的第2個特徵構成’利用將蓋部螺合於螺 紋部，可防止收容液體從進出的口部溢出’並且’當以立 姿支持著內部收納有液體收容體的支持座時’液體收容體 透過該被卡止部，被支持座的卡止部所卡止、支持。因 此，假設即使液體收容體是由比習知的該類物品更爲薄型 且自立性不足的樹脂容器或合成樹脂製的軟包材所形成之 袋狀，並且在該液體收容體中塡充了液體，液體收容體仍 可以以穩定的立姿被支持在支持座的內部。 再者，因爲設有使被卡止部無法對卡止部做相對旋轉 的旋轉阻止機構，所以，口部的方向對支持座呈現穩定。 因此，當要把蓋部面向口部旋轉時，可防止液體收容體在 支持座的內部與蓋部一起旋轉的現象，這和以往可自立的 液體收容體一樣，可輕易且確實地將蓋部旋進、裝卸於液 201247486 體收容體。 甚至，藉由利用旋轉阻止機構的作用，口部的方向對 支持座呈現穩定，所以，例如爲了容易注入收容液體，可 將口部改變成朝橫方向部份尖起的形狀，或者是甚至在支 持座裝設握把，都可使該橫向的口部經常以穩定的方向來 使用》 本發明的第3個特徵構成爲：上述被卡止部係爲一體 形成在上述口部的多角形之鍔部，上述旋轉阻止機構係具 有旋轉阻止面，該旋轉阻止面係以與上述鍔部之多角形狀 的外周部卡合的方式，形成在上述卡止部。 在利用吹製成型裝置，從預成型物來成形樹脂製的液 體收容體時，一般會在預成型物一體設置爲了卡止於成型 裝置的鍔狀之被卡止部，在成形後，該被卡止部會成爲鍔 部而殘留在口部。在本發明的第3個特徵構成中，液體收 容體的被卡止部係由形成在該口部的鍔部所構成，所以只 要在吹製成型時，預先將使預成型物卡止在成型裝置的被 卡止部形成爲多角形狀，即可在支持座的卡止部形成對應 該多角形之形狀的旋轉阻止面，藉由如此簡單的改良，即 可將爲了將預成型物卡止在成型裝置的被卡止部兼用爲旋 轉阻止機構的被卡止部，並且還可利用蓋部將內容物密封 保存。 【實施方式】 以下係根據圖面來說明本發明的實施形態。 -8 - 201247486 如圖1〜圖3所示，本發明之液體收容單元係由：瓶 狀的液體收容體3、以及以包覆著全體液體收容體3的方 式予以支持的膠囊狀之支持座7所構成。 液體收容體3係爲：將由聚酯（PET)或聚乙烯（PE)、 聚丙烯（PP)、聚苯乙烯（PS)等所形成的預成型物予以吹製 成型所得的瓶體。 在液體收容體3之可供收容液體進出的口部1係形成 有螺紋部2，合成樹脂製的蓋部4係以可自由裝卸的方式 螺合在該螺紋部2。 如圖7所示，在口部1的基端側之端部，也就是在螺 紋部2與液體收容體3之本體部之間，係一體形成了鍔部 5(被卡止部的一例）。 圖4、圖5'圖6係顯示液體收容體3在吹製成型前 的預成型物9。如這些圖所示般，液體收容體3的鍔部5 係做爲用來將預成型物9卡止在吹製成型機的被卡止部， 使一體地被設置在預成型物9的鍔部，在吹製成型後也持 續維持著。 支持座7係爲將丙烯酸樹脂、厚型的聚酯、硬質氯化 乙烯 '聚碳酸酯、厚型的聚乙烯、酚樹脂等所謂硬質的合 成樹脂等，利用射出成形等來成型者。 支持座7係如圖1〜圖3所示般，主要是由：自由圍 繞著液體收容體3之本體部，呈2個分割之膠囊狀的分割 膠囊Π;以及用來包覆液體收容體3之蓋部4的外殼構件 1 3所構成。 -9- 201247486 如圖2中的二點虛線所示，外殼構件1 3係對從分割 膠缀11的上端附近，對著朝向上方露出之液體收容體3 的蓋部4，以外嵌狀的方式來安裝。 再者，在蓋部4安裝有外殼構件13的狀態下，藉由 轉動位在外側的外殼構件1 3，即可將蓋部4裝卸於液體收 容體3的口部1。 又，在蓋部4螺合於液體收容體3连口部1的狀態 下，藉由將外殼構件1 3從液體收容體3拉開，即可將蓋 部4與外殼構件1 3分開。 分割膠㈣11彼此並非爲分離的2個構件，而是利用 被設置在底部的薄合葉部12而連結成一體。如圖2中二 點虛線所示，分割膠漢1 1彼此的開閉操作係藉由合葉部 1 2的搖動操作來進行。 因爲支持座7以及外殼構件1 3係由透明的樹脂所形 成，所以即使是在關閉支持座7，裝上外鯓構件1 3的情況 下，仍可從外側來確認被收納在內部之液體收容體3或蓋 部4的狀態。 當支持座7收納了液體收容體3時，係設有與液體收 容體3的鍔部5 (被卡止部）自然卡止的卡止部6。卡止部6 係具有在液體收容體3之長度方向上與鍔部5之下面對向 的支持面。 因此，如圖2所示，一旦在內部收納了液體收容體3 的狀態下，使支持座7呈立姿，則液體收容體3的全體， 或者是至少爲本體部之上半部等之液體收容體3的一部 -10- 201247486 份，透過鍔部5，藉由支持座7的卡止部6而可成爲實質 上的懸吊狀態。 亦即，在本發明中，在液體收容體3吹製成型時，做 爲卡止在吹製成型機之被卡止部，而被設置在預成型物9 的鍔部5，係在液體收容體3成型後，做爲卡止在構成液 體收容單元之支持座7之卡止部6的被卡止部，可再度被 利用。 此外，本發明之液體收容單元係具備：阻止被收納的 液體收容體3對著支持座7旋轉的旋轉阻止機構8。 如圖4、圖6以及圖7所示般，液體收容體3的鍔部 5係形成爲八角形等的多角形狀，旋轉阻止機構8係由： 上述多角形狀的鍔部5、以及以與鍔部5之多角形狀之外 周部卡合的方式，形成在卡止部6的旋轉阻止面1 0所構 成。 旋轉阻止面10係具備與鍔部5之多角形對應的多角 形狀’當將液體收容體3收納於支持座7時，係以鍔部5 的多角形狀大致與卡止部6之旋轉阻止面10之多角形狀 一致的方式來收納。 藉由旋轉阻止機構8的作用，液體收容體3不會在支 持座7的內部空轉，所以，在握著支持座7之外側的狀態 下’只要旋轉操作蓋部4或外殼構件13，即可使蓋部4對 液體收容體3的螺紋部2進行裝卸。 如圖2所示’支持座7的內面形狀係對應於液體收容 體3的外形’所以，形成在支持座7之內面與液體收容體 -11 - 201247486 3之間的間隙之厚度，除了口部1的附近之外，大致爲固 定。但是，支持座7並非以全體爲均一厚度來形成。 從圖2所示之支持座7的剖面形狀即能理解，支持座 7在對應於被收納之液體收容體3的本體部之大約下半部 的區域，除了局部特別薄的合葉部12以外，係具有較 薄，但大致有固定厚度的剖面形狀。但是，在對應本體部 之大約上半部的區域，基本上係具有朝向上方的卡止部6 逐漸增厚的剖面形狀。 再者，支持座7之下半部的部位雖然較薄，但是，塡 充了液體的液體收容體3在被收納於支持座7之內部的狀 態下，即使將液體收容單元立置在大約水平面上，仍具有 藉由僅支持座7之底面，就足以維持著穩定之姿勢的充分 剛性。 外殼構件1 3係具有：從包括蓋部4之上端附近的上 端，朝向與支持座7之上端面對應的下端，逐漸增厚的剖 面形狀。 此外，外殼構件1 3之下端的直徑、以及關閉之支持 座7之上端的直徑係大約一致。甚至，從外殻構件1 3的 下端朝向上方延伸之圓錐狀面的傾斜角度、以及從關閉之 支持座7的上端朝向下方延伸之圓錐狀面的傾斜角度係大 約一致。 如此一來，在關閉的支持座7之上端配置有外殼構件 13之狀態的液體收容單元的外形，大致而言，除了平坦之 支持座7的底面以及外殻構件13的上面以外，全體係呈 -12- 201247486 單純且平滑的流線型或砲彈形。 [其他實施形態] <1>液體收容體3的口部1也可以不設有蓋部4，而 爲基本上經常以開放狀態來使用的液體收容單元。此外， 也可以是：具有像軟木栓般，只要拉開即可打開之蓋子的 液體收容單元。甚至，也可以將口部1做成收容液體容易 進出的橫尖狀，此時，也可以利用旋轉阻止機構8的作 用，使口部1的方向對支持座7而言，是經常維持在穩定 的狀態下來使用。 <2>可將在液體收容體3之本體部與螺紋部2之間的 頸部形成爲多角筒狀，來做爲旋轉阻止機構8，也能以卡 入該頸部的方式，在朝向直徑方向內側突出的支持座7的 卡止部6，形成多角筒狀的旋轉阻止面10。 <3 >鍔部5的形狀也可以是如圖8、圖9中所示之八 角形以外的任何多角形，亦可爲圖1 〇所示般的橢圓形。 此外，也可以如圖11、圖12所示般，在周部形成凹凸 部。藉由事先將支持座7之卡止部6的形狀，設成具有與 這些鍔部5之外形大致相同形狀的內周面，即可完成旋轉 阻止機構8的構成。 <4>也可以如圖1 3所示般，將鍔部5的外周形狀設爲 外齒輪狀，在卡止部6形成卡合於該外齒輪狀的內齒輪狀 的凹凸部。 <5 >支持座7的液體收容體3也可以不是膠囊狀，而 -13- 201247486 是例如爲籠狀的外框形態。支持座7的材貿不限於硬質的 合成樹脂，金屬製的框架等亦可。此外，隹可將支持座7 當做保溫性的容器。 <6>液體收容體除了合成樹脂製以外》也可以是布製 或橡膠製等的袋狀物。 <7>外殼構件1 3也可以非外嵌固定在液體收容體3的 蓋部4，而是以可自由裝卸的方式連結在關閉狀態的分割 膠褒1 1之上端附近。此時，例如只要在外殼構件1 3的下 端面與分割膠逛11之上端面的一方，立躲朝向上下延伸 的筒狀突起，而在另一方設有用來壓入該突起的環狀溝部 即可。 再者，如上述般，爲了便於與圖面做對照雖設有符 號’但是本發明並非根據該記載而只限定在所添附之圖面 的構成。此外，在不脫離本發明要旨的範_內，當然可以 各種樣態來加以實施》 【圖式簡單說明】 [圖1]係爲收容了液體收容體之支持座的正面圖。 [圖2]係爲收容了液體收容體之支持座的縱剖面圖。 [圖3]係爲收容了液體收容體之支持座的要部縱剖面 圖。 [圖4]係爲顯示液體收容體之預成型物的平面圖。 [圖5]係爲顯示液體收容體之預成型物的正面圖。 [圖6]係爲顯示液體收容體之預成型物的立體圖。 -14 -

Description of the Invention: [Technical Field of the Invention] The present invention relates to a liquid storage unit associated with a liquid container having a liquid accommodating body. [Prior Art] A bottle such as a bottle of the above-mentioned liquid container is easy to be mass-produced because of molding, and has excellent characteristics such as high mechanical strength, so that it is filled with various liquids in a wide range of fields. Liquid container. However, in recent years, a liquid made of such a synthetic resin has been quantified or reduced in thickness in order to save energy and reduce the environmental load. However, the more the liquid container made of synthetic resin is, the more the liquid container is placed on the table in a standing position, and the self-standing difference tends to be difficult to store. In addition, the liquid container is also ruined during use, and the liquid contained therein overflows. There are no suitable solutions to these problems (there is no patent document). [Problem to be Solved by the Invention] Therefore, in view of the above-mentioned problems, the present invention provides a method in which the thickness of the liquid container is reduced, and the resin can be made into a mouth-like synthetic resin. However, the volume is used as a container, and it is becoming more and more careless based on the active pursuit of light-weight thinning. At present, it is good for the literature and non-special purpose to maintain the liquidity of the liquid container and easy to maintain 201247486. The liquid storage unit used. [Means for Solving the Problem] The first aspect of the present invention includes: a liquid container in which a locked portion is provided in a mouth portion into which a liquid can be accommodated, and a support for storing the liquid container; The support base has a locking portion that locks between the locked portion and the locked portion when the liquid container is supported in a standing posture A rotation preventing mechanism that prevents relative rotation with respect to each other is provided. According to the first aspect of the present invention, when the holder for accommodating the liquid container is accommodated in a standing posture, the liquid is accommodated, and the body is locked by the locking portion of the holder by the holder. . Therefore, it is assumed that even if the liquid container is a bag formed of a resin container or a soft resin material which is thinner than the conventional article and has insufficient self-standing property, and even in the liquid container When the liquid is smashed, the liquid squeezing body is still inside the support seat and is supported in a stable standing position. In addition, since the rotation preventing mechanism for preventing the locked portion from rotating relative to the locking portion is provided, the mouth portion is provided. The direction can be fixed to the support. Therefore, even when the screw-type cover portion is attached to the mouth of the liquid container, when the lid portion is to be rotated toward the mouth portion, the liquid container can be prevented from rotating together with the lid portion inside the holder, so that it is easy And the cover portion is screwed in and attached to the liquid container. Even by using the action of the rotation preventing mechanism, the direction of the mouth is stable to the support seat, so even if it is easy to inject the liquid, the mouth of the -6 - 201247486 is changed to a shape that is partially pointed in the lateral direction' or Even in the support seat, the lateral mouth can often be used in a stable direction. According to a second aspect of the present invention, there is provided a liquid storage body in which a screw portion for screwing a lid portion is provided in a mouth portion into which a liquid can be accommodated, and a support base for supporting the liquid container; The locking portion is configured to 'lock and support the locked portion' when the liquid container is supported in a standing posture. The locked portion is provided in the liquid more than the threaded portion of the mouth portion. The body portion side 'between the locked portion and the locking portion' of the housing is provided with a rotation preventing mechanism that prevents relative rotation therebetween. According to the second aspect of the present invention, it is possible to prevent the liquid from being escaping from the mouth of the inlet and outlet by screwing the lid portion to the threaded portion, and to "support" when the support portion of the liquid container is accommodated in a standing posture. The container passes through the locked portion, and is locked and supported by the locking portion of the support. Therefore, it is assumed that the liquid container is formed into a bag shape formed of a resin container which is thinner than the conventional article and has a low self-standing property, or a soft resin material made of a synthetic resin, and is filled with the liquid in the liquid container. The liquid container can still be supported inside the support seat in a stable standing position. Further, since the rotation preventing mechanism that prevents the locked portion from rotating relative to the locking portion is provided, the direction of the mouth portion is stabilized against the support. Therefore, when the lid portion is to be rotated toward the mouth portion, the liquid container can be prevented from rotating together with the lid portion inside the holder, which can easily and surely cover the lid portion as in the conventional self-standing liquid container. Screw in, load and unload liquid 201247486 body container. Even by the action of the rotation preventing mechanism, the direction of the mouth portion is stabilized against the support seat, so that, for example, in order to easily inject the liquid, the mouth portion can be changed into a shape that is partially pointed in the lateral direction, or even In the support seat mounting grip, the horizontal mouth portion can be used in a stable direction. The third feature of the present invention is that the locked portion is formed in a polygonal shape integrally formed in the mouth portion. In the crotch portion, the rotation preventing mechanism has a rotation preventing surface formed on the locking portion so as to be engaged with the outer peripheral portion of the polygonal portion of the crotch portion. When a liquid container made of a resin is molded from a preform by a blow molding device, generally, a predetermined locking portion for locking in a molding device is provided in the preform, and after molding, the molding is performed. The locked portion becomes a crotch portion and remains in the mouth portion. In the third characteristic configuration of the present invention, since the locked portion of the liquid container is constituted by the crotch portion formed in the mouth portion, the preform is locked in advance as long as the blow molding is performed. The locked portion of the molding device is formed in a polygonal shape, so that a rotation preventing surface corresponding to the polygonal shape can be formed in the locking portion of the holder, and the preform can be locked by such a simple improvement. The locked portion of the molding apparatus also serves as a locked portion of the rotation preventing mechanism, and the contents can be sealed and stored by the lid portion. [Embodiment] Hereinafter, embodiments of the present invention will be described based on the drawings. -8 - 201247486 As shown in FIG. 1 to FIG. 3, the liquid storage unit of the present invention is composed of a bottle-shaped liquid container 3 and a capsule-shaped holder supported to cover the entire liquid container 3. 7 constitutes. The liquid container 3 is a bottle obtained by blow molding a preform formed of polyester (PET), polyethylene (PE), polypropylene (PP), polystyrene (PS) or the like. The thread portion 2 is formed in the mouth portion 1 of the liquid container 3 into which the liquid can be taken in and out, and the synthetic resin cover portion 4 is detachably screwed to the screw portion 2. As shown in Fig. 7, at the end portion on the proximal end side of the mouth portion 1, that is, between the screw portion 2 and the main body portion of the liquid container 3, the crotch portion 5 is integrally formed (an example of the engaged portion) . Fig. 4 and Fig. 5' Fig. 6 show the preform 9 before the liquid container 3 is blown. As shown in these figures, the crotch portion 5 of the liquid container 3 is used to lock the preform 9 to the engaged portion of the blow molding machine so as to be integrally provided in the preform 9. The crotch is also maintained after being blow molded. The support base 7 is formed by injection molding or the like using a so-called hard synthetic resin such as an acrylic resin, a thick polyester, a hard chlorinated ethylene 'polycarbonate, a thick polyethylene or a phenol resin. As shown in FIG. 1 to FIG. 3, the support base 7 is mainly composed of two divided capsule-shaped divided capsules that are freely surrounded by the body portion of the liquid container 3, and is used to cover the liquid container 3; The outer casing member 13 of the lid portion 4 is formed. -9- 201247486 As shown by the two-dotted line in Fig. 2, the outer casing member 13 is in a manner of being fitted in the vicinity of the upper end of the split glue 11 and facing the lid portion 4 of the liquid container 3 exposed upward. To install. Further, in a state where the outer casing member 13 is attached to the lid portion 4, the lid portion 4 can be attached and detached to the mouth portion 1 of the liquid container 3 by the outer casing member 13 being rotated. Further, in a state where the lid portion 4 is screwed to the mouth portion 1 of the liquid container 3, the lid member 4 can be separated from the outer shell member 13 by pulling the outer shell member 13 from the liquid container 3. The split rubbers (four) 11 are not separated from each other, but are integrally joined by the thin blade portions 12 provided at the bottom. As shown by the two-dotted line in Fig. 2, the opening and closing operations of the split plastics 1 are performed by the shaking operation of the hinge portion 12. Since the support base 7 and the outer casing member 13 are formed of a transparent resin, even when the outer support member 13 is attached to the support base 7, the liquid storage accommodated inside can be confirmed from the outside. The state of the body 3 or the cover portion 4. When the holder 7 accommodates the liquid container 3, the locking portion 6 that is naturally locked to the crotch portion 5 (the locked portion) of the liquid container 3 is provided. The locking portion 6 has a support surface that faces the lower surface of the crotch portion 5 in the longitudinal direction of the liquid container 3. Therefore, as shown in FIG. 2, when the support base 7 is in a standing posture in a state in which the liquid container 3 is housed therein, the entire liquid container 3 or at least the upper portion of the body portion or the like is accommodated in the liquid. One portion of the body 3 - 10,047,476,486 passes through the crotch portion 5 and is substantially suspended by the locking portion 6 of the support base 7. That is, in the present invention, when the liquid container 3 is blown, it is locked in the locked portion of the blow molding machine, and is provided in the crotch portion 5 of the preform 9 After the liquid container 3 is molded, it can be reused as a locked portion that is locked to the locking portion 6 of the holder 7 constituting the liquid storage unit. Further, the liquid storage unit of the present invention includes a rotation preventing mechanism 8 that prevents the liquid container 3 to be stored from rotating against the holder 7. As shown in FIG. 4, FIG. 6, and FIG. 7, the crotch portion 5 of the liquid container 3 is formed in a polygonal shape such as an octagonal shape, and the rotation preventing mechanism 8 is composed of the above-described polygonal crotch portion 5 and The outer peripheral portion of the polygonal shape of the portion 5 is formed so as to be engaged with the rotation preventing surface 10 of the locking portion 6. The rotation preventing surface 10 is provided with a polygonal shape corresponding to the polygonal shape of the crotch portion 5. When the liquid container 3 is housed in the support base 7, the polygonal shape of the crotch portion 5 is substantially the same as the rotation preventing surface 10 of the locking portion 6. The polygonal shape is stored in a consistent manner. By the action of the rotation preventing mechanism 8, the liquid container 3 does not idling inside the holder 7, so that the lid portion 4 or the outer casing member 13 can be rotated by simply operating the lid portion 4 or the outer casing member 13 while holding the outer side of the holder 7. The lid portion 4 detaches the screw portion 2 of the liquid container 3 . As shown in FIG. 2, 'the inner surface shape of the support base 7 corresponds to the outer shape of the liquid container 3', so the thickness of the gap formed between the inner surface of the support base 7 and the liquid container -11 - 201247486 3 is excluded. The vicinity of the mouth 1 is substantially fixed. However, the support base 7 is not formed in a uniform thickness as a whole. It can be understood from the cross-sectional shape of the support base 7 shown in Fig. 2 that the support base 7 is in a region corresponding to the lower half of the main body portion of the liquid container 3 to be accommodated, except for the partially thin hinge portion 12. It has a thin, but generally fixed, cross-sectional shape. However, the region corresponding to the upper half of the main body portion basically has a cross-sectional shape in which the locking portion 6 toward the upper portion is gradually thickened. Further, although the portion of the lower half of the support base 7 is thin, the liquid storage body 3 filled with the liquid is placed in the inside of the support base 7, even if the liquid storage unit is placed at approximately the horizontal plane. Above, there is still sufficient rigidity to maintain a stable posture by supporting only the bottom surface of the seat 7. The outer casing member 13 has a cross-sectional shape which is gradually thickened from the upper end including the vicinity of the upper end of the lid portion 4 toward the lower end corresponding to the upper end surface of the support base 7. Further, the diameter of the lower end of the outer casing member 13 and the diameter of the upper end of the closed support base 7 are approximately the same. Further, the inclination angle of the conical surface extending upward from the lower end of the outer casing member 13 and the inclination angle of the conical surface extending downward from the upper end of the closed support seat 7 are approximately the same. In this way, the outer shape of the liquid storage unit in the state in which the outer casing member 13 is disposed at the upper end of the closed support base 7 is substantially the entire system except for the bottom surface of the flat support base 7 and the upper surface of the outer casing member 13. -12- 201247486 Simple and smooth streamlined or shell-shaped. [Other Embodiments] <1> The mouth portion 1 of the liquid container 3 may be a liquid storage unit that is basically used in an open state without providing the lid portion 4. Further, it may be a liquid storage unit having a lid that can be opened as long as it is opened like a cork stopper. In addition, the mouth portion 1 can be formed into a horizontal shape in which the liquid can easily enter and exit. In this case, the rotation preventing mechanism 8 can be used to maintain the stability of the mouth portion 1 against the support base 7. The state is used down. <2> The neck portion between the main body portion of the liquid container 3 and the screw portion 2 can be formed into a polygonal tube shape as the rotation preventing mechanism 8, and can be inserted in the neck portion. The locking portion 6 of the holder 7 projecting inward in the diameter direction forms a polygonal barrel-shaped rotation preventing surface 10. <3 > The shape of the crotch portion 5 may be any polygonal shape other than the octagonal shape as shown in Figs. 8 and 9, or may be an elliptical shape as shown in Fig. 1 . Further, as shown in Figs. 11 and 12, irregularities may be formed in the peripheral portion. The configuration of the rotation preventing mechanism 8 can be completed by previously setting the shape of the locking portion 6 of the support base 7 to have an inner circumferential surface having substantially the same shape as the outer shape of the crotch portion 5. <4> As shown in Fig. 13, the outer peripheral shape of the crotch portion 5 may be an outer gear shape, and the locking portion 6 may be formed with an inner gear-like concavo-convex portion that is engaged with the outer gear shape. <5 > The liquid container 3 of the holder 7 may not be in the form of a capsule, and -13-201247486 is, for example, a cage-like frame shape. The material trade of the support base 7 is not limited to a hard synthetic resin, and a metal frame or the like may be used. In addition, the support 7 can be used as a container for insulation. <6> The liquid container may be a bag made of cloth or rubber, in addition to a synthetic resin. <7> The outer casing member 13 may be detachably attached to the lid portion 4 of the liquid container 3, and may be detachably connected to the vicinity of the upper end of the divided capsule 11 in the closed state. In this case, for example, one of the lower end faces of the outer casing member 13 and the upper end surface of the divided rubber wrap 11 is placed to hide the cylindrical projection extending upward and downward, and the other is provided with an annular groove for press-fitting the projection. can. Further, as described above, in order to facilitate comparison with the drawing, the symbol ' is provided, but the present invention is not limited to the configuration of the attached drawing based on the description. Further, it is a matter of course that the invention can be carried out in various forms without departing from the gist of the present invention.
