發明概要
發明欲解決之課題
在如上的可撓性容器中，需要如下作業，例如，在開封時解開將花冠狀的蓋固定著的繩帶而打開蓋，拉出內袋的排出口部，切斷排出口部之前端之經過熱密封的部分，解開綁縛著排出口部的繩帶。然而，由於下部開口是形成在外袋的底面部，如此的開封作業對於站在可撓性容器之側方的作業者未必容易。又，裝有內容物之可撓性容器常常重量較重，且難以傾斜，因此在此種情況特別是開封作業也變難。SUMMARY OF THE INVENTION The problem to be solved by the present invention requires the following operations in the flexible container as described above. For example, when opening the lid, the rope with the corolla-shaped lid fixed is opened, the lid is opened, and the outlet of the inner bag is pulled out. The heat-sealed portion of the front end of the discharge port portion is cut off, and the rope that binds the discharge port portion is released. However, since the lower opening is formed on the bottom surface of the outer bag, such an unsealing operation is not necessarily easy for an operator standing on the side of the flexible container. In addition, flexible containers containing contents are often heavy and difficult to tilt, so in this case, especially the unsealing operation becomes difficult.

本發明是以提供可容易開封的可撓性容器及其製造方法為目的。
解決課題之手段The present invention aims to provide a flexible container that can be easily opened and a method for manufacturing the same.

Invention effect

根據本發明，從外袋的底面部伸出之內袋的排出口部被安裝在底面部之外側的蓋所覆蓋。因此，可撓性容器開封時，作業者可容易從可撓性容器的側方朝其下方伸手拆下蓋。又，作業者從相同側伸手，而從內袋的排出口部解開將其綁縛的第1綑綁具，可打開排出口部。因此，作業者未必須要站在可撓性容器的下方進行排出口部的開封作業，亦可從側方開封。因此，可撓性容器的開封會變容易。According to the present invention, the discharge port portion of the inner bag protruding from the bottom surface portion of the outer bag is covered with a cover mounted on the outer side of the bottom surface portion. Therefore, when the flexible container is unsealed, an operator can easily remove the lid by reaching down from the side of the flexible container to the lower side. In addition, the operator extends his hand from the same side, and releases the first binding device that binds the first binding device from the discharge port portion of the inner bag to open the discharge port portion. Therefore, the operator does not have to stand under the flexible container to perform the unsealing operation of the discharge port portion, and the unsealing can also be performed from the side. Therefore, it is easy to open the flexible container.

又，根據以上第2觀點，在開封時以外，內袋的排出口部朝一方折返後被擰緊(或者，在擰緊後予以折返)，並以第1綑綁具綁縛，以保持其狀態，進而被綑綁之狀態的排出口部被折疊後而被蓋覆蓋。內袋的排出口部是位於內袋及外袋之最下端部的附近，並且在將可撓性容器懸吊以搬送時，容易朝左右大幅晃動(即，容易鬆軟)，容易與蓋干擾的部分。當排出口部與蓋過度干擾時，可能會不小心打開蓋。然而，根據以上的第2觀點，除了開封時，由於排出口部在經過折返的狀態下是以第1綑綁具綁縛，因此成為排出口部之最下端的位置會變得稍微高，難以與蓋干擾。因此，在搬送時，即使被蓋覆蓋的排出口部鬆軟，也可以防止蓋不小心打開。In addition, according to the second aspect above, the opening of the inner bag is turned back to one side after being opened (or turned back after being tightened) except for the time of opening, and is bound with the first binding device to maintain its state, and further The bundled discharge port is folded and covered with a cover. The discharge opening of the inner bag is located near the lower end of the inner bag and the outer bag. When the flexible container is suspended for transportation, it is easy to shake to the left and right (that is, easy to loosen), and it is easy to interfere with the cover. section. The cover may be accidentally opened when the discharge port part interferes with the cover excessively. However, according to the second viewpoint above, except when unsealing, since the discharge port portion is bound by the first binding device in a folded state, the position at the lower end of the discharge port portion becomes slightly higher, making it difficult to communicate with Cover interference. Therefore, even when the discharge port portion covered by the cover is soft during transportation, the cover can be prevented from being accidentally opened.

FIG. 1 is a side view showing a flexible container (hereinafter, sometimes simply referred to as a container) 1 according to this embodiment (however, a cover 5 to be described later is omitted). The flexible container 1 is a container for containing contents, and is used for storing and transporting the contents. The flexible container 1 is made of a soft material, as the name suggests. Therefore, the container 1 is three-dimensionally expanded in a state of being filled with contents, but can be folded into a flat shape in a state of headroom. The upper and lower portions of the flexible container 1 are folded in a predetermined method to be described later, and the shape is arranged. FIG. 1 shows a state in which the upper and lower portions of the container 1 are unfolded. The type of the contents to be filled in the container 1 is not particularly limited, but is typically powder, granules, cereals, vegetables, or the like, and in this embodiment, it is water-absorbent resin particles (small round particles).

可撓性容器1是雙層構造，具備：外袋2、及容置於外袋2內的內袋3(參照圖6)。內容物填充於內袋3的內部。外袋2的本體部20具有上表面部21、底面部22及側表面部23。本實施形態中，上表面部21及底面部22為正方形。即，外袋2的本體部20是略立方體形狀，側表面部23包含矩形的4個側表面部。於側表面部23，安裝有***標籤等的袋23a。在上表面部21的中央形成有開口(以下，稱為上部開口)21a。同樣地，在底面部22的中央形成有開口(以下，稱為下部開口)22a。開口21a、22a在本實施形態皆為圓形。再者，本來圖1的側面圖看不到開口21a、22a，但是為了參考，其位置陰影來表示。本體部20、上表面部21、底面部22及開口21a、22a是配置成同軸，以下，將其等共通的中心軸以符號A1表示。The flexible container 1 has a double-layer structure and includes an outer bag 2 and an inner bag 3 (see FIG. 6) accommodated in the outer bag 2. The contents are filled inside the inner bag 3. The body portion 20 of the outer bag 2 includes an upper surface portion 21, a bottom surface portion 22, and a side surface portion 23. In this embodiment, the upper surface part 21 and the bottom surface part 22 are square. That is, the body portion 20 of the outer bag 2 has a substantially cubic shape, and the side surface portion 23 includes four rectangular side surface portions. A bag 23 a into which a label or the like is inserted is attached to the side surface portion 23. An opening (hereinafter, referred to as an upper opening) 21 a is formed in the center of the upper surface portion 21. Similarly, an opening (hereinafter, referred to as a lower opening) 22 a is formed in the center of the bottom surface portion 22. The openings 21a and 22a are both circular in this embodiment. It should be noted that the openings 21a and 22a cannot be seen in the side view of FIG. 1. However, for reference, the positions are shaded. The main body part 20, the upper surface part 21, the bottom surface part 22, and the openings 21a and 22a are arranged coaxially. Hereinafter, the central axis which is common to these is represented by the symbol A1.

內袋3為筒狀。內袋3的上部經由上部開口21a而往上表面部21的上方伸出，形成了內容物的填充口部31。又，內袋3的下部經由下部開口22a而往底面部22的下方伸出，形成了內容物的排出口部32。內容物經由填充口部31而填充於內袋3內，並經由排出口部32而從內袋3內排出。即，填充口部31形成有用以將內容物填充於內袋3內的投入路R1，排出口部32形成有用以將內容物從內袋3內排出的排出路R2。The inner bag 3 is cylindrical. The upper portion of the inner bag 3 projects above the upper surface portion 21 through the upper opening 21a, and forms a filling mouth portion 31 for the contents. In addition, the lower portion of the inner bag 3 projects below the bottom surface portion 22 through the lower opening 22a, and forms a discharge port portion 32 for the contents. The contents are filled in the inner bag 3 through the filling mouth portion 31 and discharged from the inner bag 3 through the discharge port portion 32. That is, the filling port portion 31 forms an input path R1 to fill the contents in the inner bag 3, and the discharge port portion 32 forms a discharge path R2 to discharge the contents from the inner bag 3.

外袋2具有從上部開口21a往上表面部21的上方伸出之筒狀的填充口蓋25，並且更具有從下部開口22a往下方伸出之筒狀的排出口蓋26。填充口蓋25是從外側覆蓋經由上部開口21a而從上表面部21突出之內袋3之填充口部31的蓋，排出口蓋26是從外側覆蓋經由下部開口22a而從底面部22突出之內袋3之排出口部32的蓋。填充口蓋25以縫固等的態樣固定於上表面部21，配置成從界定上部開口21a的邊緣附近豎立。填充口蓋25的截面形狀與上部開口21a是略同尺寸的圓形。同樣地，排出口蓋26以縫固等的態樣固定於底面部22，配置成從界定下部開口22a的邊緣附近豎立。排出口蓋26的截面形狀與下部開口22a是略同尺寸的圓形。The outer bag 2 includes a cylindrical filling port cover 25 that extends from the upper opening 21a to the upper surface portion 21, and further includes a cylindrical discharge port cover 26 that extends from the lower opening 22a. The filling mouth cover 25 is a cover covering the filling mouth portion 31 of the inner bag 3 protruding from the upper surface portion 21 through the upper opening 21a from the outside, and the discharge port cover 26 is an inner bag covering the outer bag 3 protruding from the bottom surface portion 22 through the lower opening 22a. The cover of the discharge opening section 32 of 3rd. The filling mouth cover 25 is fixed to the upper surface portion 21 in a state such as being sewn, and is arranged to stand from the vicinity of the edge defining the upper opening 21a. The cross-sectional shape of the filling port cover 25 is a circle having a size approximately the same as that of the upper opening 21a. Similarly, the discharge port cover 26 is fixed to the bottom surface portion 22 in a state such as being sewn, and is arranged to stand from the vicinity of the edge defining the lower opening 22a. The cross-sectional shape of the discharge port cover 26 and the lower opening 22a are circular in the same size.

外袋2的本體部20的直徑比填充口蓋25及排出口蓋26還大。又，內袋3在中心軸A1的方向上，直徑是固定的，其直徑比填充口蓋25及排出口蓋26的直徑還大。因此，內袋3的上部(填充口部31)容置在外袋2內時，形成皺摺，直徑會縮小。同樣地，內袋3的下部(排出口部32)也是在容置於外袋2內時會形成皺摺，直徑會縮小。如以上所述，由於填充口部31與填充口蓋25一起形成填充口，因此，以下有時候會將填充口部31及填充口蓋25合併稱為填充埠P1。同樣地，由於排出口部32與排出口蓋26一起形成排出口，因此，以下有時候會將排出口部32及排出口蓋26合併稱為排出埠P2。The diameter of the body portion 20 of the outer bag 2 is larger than the filling port cover 25 and the discharge port cover 26. In addition, the inner bag 3 has a constant diameter in the direction of the central axis A1, and its diameter is larger than the diameters of the filling port cover 25 and the discharge port cover 26. Therefore, when the upper portion (filling mouth portion 31) of the inner bag 3 is accommodated in the outer bag 2, wrinkles are formed and the diameter is reduced. Similarly, when the lower portion (the discharge port portion 32) of the inner bag 3 is contained in the outer bag 2, wrinkles are formed and the diameter is reduced. As described above, the filling port portion 31 and the filling port cover 25 form a filling port together. Therefore, the filling port portion 31 and the filling port cover 25 may be collectively referred to as a filling port P1 hereinafter. Similarly, since the discharge port portion 32 and the discharge port cover 26 form a discharge port, the discharge port portion 32 and the discharge port cover 26 may be collectively referred to as a discharge port P2 hereinafter.

其次，就排出埠P2附近的構成進行說明。排出埠P2是藉由綑綁具40(第1綑綁具)綁縛以封閉排出路R2。本實施形態中，綑綁具40是如圖1所示，固定在排出口蓋26的外表面。綑綁具40是具有黏扣42、43之帶狀的構件(以下，稱為繩帶)41。繩帶41在未綁縛排出埠P2的狀態下，是以朝水平方向延伸地縫固在排出口蓋26之上下方向的中央附近等的態樣安裝。黏扣42、43是彼此互相黏固的構造，沿著繩帶41的長向方向隔著間隔配置。再者，於圖1及圖2，顯示了本來因為配置在繩帶41的相反側而看不到的黏扣43的位置作為參考。<1-1. Structure near the discharge port>
Next, a configuration near the discharge port P2 will be described. The discharge port P2 is bound by a binding device 40 (first binding device) to close the discharge path R2. In this embodiment, the binding tool 40 is fixed to the outer surface of the discharge port cover 26 as shown in FIG. 1. The binding tool 40 is a belt-shaped member (hereinafter, referred to as a string) 41 having hooks 42 and 43. The string 41 is attached in a state in which the discharge port P2 is not bound, and is sewed to the center near the center of the discharge port cover 26 in the vertical direction so as to extend horizontally. The hook-and-loop fasteners 42 and 43 are mutually adhere | attached structures, and are arrange | positioned at intervals along the longitudinal direction of the string 41. In addition, in FIG. 1 and FIG. 2, the position of the hook-and-loop fastener 43 which was originally invisible because it was arrange | positioned on the opposite side of the string 41 was shown as a reference.

要封閉排出路R2時，首先，將排出口部32與覆蓋排出口部32的排出口蓋26一起擰緊以封閉排出路R2。其後，如圖2所示，將排出口部32與排出口蓋26一起朝一方折返，以綑綁具40綁縛排出埠P2，以保持該折返的狀態。圖2是顯示將排出埠P2折返，並以綑綁具40固定住的樣態的圖。此時，排出埠P2是其下端折曲成向上，藉此在彼此相向的部位，被繩帶41捲繞。接著，藉由固定在繩帶41的黏扣42、43，固定繩帶41的捲繞狀態。To close the discharge path R2, first, the discharge port portion 32 and the discharge port cover 26 covering the discharge port portion 32 are tightened together to close the discharge path R2. Thereafter, as shown in FIG. 2, the discharge port portion 32 and the discharge port cover 26 are folded back to one side, and the discharge port P2 is bound by the binding tool 40 to maintain the folded state. FIG. 2 is a diagram showing a state in which the discharge port P2 is folded back and fixed by the binding tool 40. At this time, the lower end of the discharge port P2 is bent upward, thereby being wound by the cord 41 at the portions facing each other. Next, the rolled state of the string 41 is fixed by the hooks 42 and 43 fixed to the string 41.

圖3及圖4是可撓性容器1的仰視圖。如同圖所示，可撓性容器1具備蓋5，蓋5可對底面部22自由裝卸地安裝，以開閉下部開口22a。蓋5在封閉下部開口22a時安裝於底面部22的外側。蓋5成片狀，在本實施形態中為矩形。在蓋5中與底面部22對向的內表面5a，沿著外周部而大致等間隔地以縫固等的態樣固定有黏扣51。另一方面，黏扣52以縫固等的態樣固定在底面部22中與黏扣51對向的部位。接著，藉由該等黏扣51、52互相黏固，蓋5安裝於底面部22。再者，在圖3及圖4，顯示了安裝於蓋5的內表面且從外側看不到的黏扣51的位置作為參考。3 and 4 are bottom views of the flexible container 1. As shown in the figure, the flexible container 1 includes a lid 5 that can be detachably attached to the bottom surface portion 22 to open and close the lower opening 22a. The cover 5 is attached to the outside of the bottom surface portion 22 when closing the lower opening 22a. The cover 5 has a sheet shape and is rectangular in this embodiment. An inner surface 5 a facing the bottom surface portion 22 in the cover 5 is fixed with a hook-and-loop fastener 51 at substantially regular intervals along the outer peripheral portion in a state of being sewn or the like. On the other hand, the hook-and-loop fastener 52 is fixed to a portion of the bottom surface portion 22 facing the hook-and-loop fastener 51 in a state such as sewn. Then, the lids 5 and 52 are fixed to each other, and the cover 5 is mounted on the bottom surface portion 22. 3 and 4 show the position of the hook-and-loop fastener 51 attached to the inner surface of the cover 5 and not visible from the outside as a reference.

當蓋5安裝於底面部22時，排出埠P2其整體會被蓋5覆蓋而無法從外部看出。更具體而言，排出埠P2被綑綁具40綁縛後折疊，並將蓋5安裝於底面部22，以覆蓋該折疊的排出埠P2。此時，排出埠P2是被容置而夾在蓋5與底面部22之間。圖4是將蓋5拆開一半左右之狀態的可撓性容器1的仰視圖。如圖4所示，當從底面部22拆下蓋5時，被綑綁具40綁縛之狀態的排出埠P2從底面部22露出。此時，排出埠P2因為重力而往下垂，從側方來看成為圖2的狀態。When the cover 5 is mounted on the bottom surface portion 22, the entirety of the discharge port P2 is covered by the cover 5 and cannot be seen from the outside. More specifically, the discharge port P2 is bound by the binding tool 40 and folded, and the cover 5 is mounted on the bottom surface portion 22 to cover the folded discharge port P2. At this time, the discharge port P2 is accommodated and sandwiched between the cover 5 and the bottom surface portion 22. FIG. 4 is a bottom view of the flexible container 1 in a state where the cover 5 is detached by about half. As shown in FIG. 4, when the cover 5 is removed from the bottom surface portion 22, the discharge port P2 in a state bound by the binding device 40 is exposed from the bottom surface portion 22. At this time, the discharge port P2 sags due to gravity, and becomes the state of FIG. 2 from a side view.

＜1-2.填充埠附近的構成＞
其次，就填充埠P1附近的構造進行說明。填充埠P1被綑綁具45(第2綑綁具)綁縛而封閉投入路R1。在本實施形態中，綑綁具45是如圖1所示般，固定在填充口蓋25的外表面。綑綁具45為繩帶狀的構件。綑綁具45是以縫固在填充口蓋25之上下方向的中央附近等的態樣安裝成在未綁縛填充埠P1的狀態下朝水平方向延伸。<1-2. Structure near the filling port>
Next, a structure near the filling port P1 will be described. The filling port P1 is bound by the binding tool 45 (second binding tool) and closes the input path R1. In this embodiment, the binding tool 45 is fixed to the outer surface of the filling opening cover 25 as shown in FIG. 1. The binding tool 45 is a string-like member. The binding tool 45 is attached to the center near the center of the filling port cover 25 in the up-down direction, and is attached to extend in the horizontal direction in a state where the filling port P1 is not bound.

要封閉投入路R1時，首先，將填充口部31與覆蓋填充口部31的填充口蓋25一起擰緊以封閉投入路R1。其後，綑綁具45捲繞填充埠P1以保持該擰緊的狀態。此時，綑綁具45是以例如蝴蝶結等的方法打結。更具體而言，亦可為如下構成：將填充口蓋25與填充口部31一起以單結打結，其後，以填充口部31的前端向下的方式，將從填充口蓋25突出的填充口部31朝一方折返，將填充口部31之該折返的部分與填充口蓋25以蝴蝶結打結。To close the input path R1, first, the filling port portion 31 and the filling port cover 25 covering the filling port portion 31 are tightened together to close the input path R1. Thereafter, the binding tool 45 is wound around the filling port P1 to maintain the tightened state. At this time, the binding tool 45 is knotted by a method such as a bow. More specifically, the filling mouth cover 25 and the filling mouth portion 31 may be knotted together in a single knot, and thereafter, the filling protruding from the filling mouth cover 25 with the front end of the filling mouth portion 31 facing downward may be formed. The mouth portion 31 is folded back to one side, and the folded-back portion of the filling mouth portion 31 and the filling mouth cover 25 are tied with a bow.

外袋2具有用以將上部開口21a開閉之花冠狀的蓋(以下，稱為花冠蓋)24。圖5是將花冠蓋24封閉之狀態之外袋2的俯視圖。花冠蓋24包含複數個花瓣狀的部位(以下，稱為花瓣部)24a。該等花瓣部24a在花冠蓋24的封閉狀態繞著中心軸A1呈放射狀配列，覆蓋上部開口21a而其中央部除外。花瓣部24a具有彼此相同的形狀，各個為略梯形，但底邊是對應於上部開口21a之輪廓的圓弧狀。即，花瓣部24a的底邊連續於上表面部21中界定上部開口21a的邊緣。The outer bag 2 has a corolla-shaped cover (hereinafter, referred to as a corolla cover) 24 for opening and closing the upper opening 21a. FIG. 5 is a plan view of the outer bag 2 with the corolla cover 24 closed. The corolla cover 24 includes a plurality of petal-shaped portions (hereinafter, referred to as petal portions) 24 a. The petal portions 24a are arranged radially around the central axis A1 in the closed state of the corolla cover 24, and cover the upper opening 21a except for the central portion. The petal portions 24 a have the same shape as each other, each of which is slightly trapezoidal, but the bottom edge is in the shape of an arc corresponding to the outline of the upper opening 21 a. That is, the bottom edge of the petal portion 24 a is continuous to the edge that defines the upper opening 21 a in the upper surface portion 21.

在花瓣部24a之內側的端部附近，形成有相對於中心軸A1朝周方向延伸之穿繩通路，一條繩帶24b插通於該等通路。未插通於穿繩通路的繩帶24b的兩端部，是藉由滑動件24c而集中。接著，該滑動件24c沿著2條繩帶24b之束移動，藉此開閉花冠蓋24。具體而言，使滑動件24c移動以使由繩帶24b形成之環圈變小時，即以繩帶24b綁縛時，花瓣部24a會倒下而在與上表面部21同一平面內展開，成為圖5所示之閉狀態。另一方面，使滑動件24c移動而使藉由繩帶24b形成的環圈變大時，即鬆開繩帶24b時，如圖1所示，可使花瓣部24a朝上下方向直立地豎立。Near the inner end of the petal portion 24a, there are formed rope passages extending in the circumferential direction with respect to the central axis A1, and a rope 24b is inserted into these passages. Both ends of the rope 24b which is not inserted in the rope passage are concentrated by the slider 24c. Then, the slider 24c moves along the bundle of the two ropes 24b, thereby opening and closing the corolla cover 24. Specifically, when the slider 24c is moved so that the loop formed by the strap 24b becomes small, that is, when the strap 24b is bound, the petal portion 24a falls down and spreads out in the same plane as the upper surface portion 21 to become The closed state shown in FIG. 5. On the other hand, when the slider 24c is moved to increase the loop formed by the strap 24b, that is, when the strap 24b is released, as shown in FIG. 1, the petal portion 24a can be erected upright.

如圖1所示，填充口蓋25配置於花冠蓋24的內側。即，花冠蓋24以從外側包圍填充口蓋25的方式固定在上表面部21。又，在填充口蓋25的外側且花冠蓋24的內側，配置內蓋4。內蓋4也是被花冠蓋24從外側包圍。被綑綁具45綁縛的填充埠P1可適宜地折疊，容置於花冠蓋24的內側，其後，封閉花冠蓋24。此時，內蓋4在花冠蓋24的內側中，從上側覆蓋填充埠P1。再者，花冠蓋24如圖5所示不需要完全地封閉。即，亦可使填充埠P1部分地從形成於花冠蓋24之中央部的開口24d突出。As shown in FIG. 1, the filling mouth cover 25 is arranged inside the corolla cover 24. That is, the corolla cover 24 is fixed to the upper surface portion 21 so as to surround the filling opening cover 25 from the outside. Further, an inner cover 4 is arranged outside the filling mouth cover 25 and inside the corolla cover 24. The inner cover 4 is also surrounded from the outside by a corolla cover 24. The filling port P1 bound by the binding tool 45 can be appropriately folded and accommodated inside the corolla cover 24, and thereafter, the corolla cover 24 is closed. At this time, the inner cover 4 covers the filling port P1 from the upper side in the inner side of the corolla cover 24. Moreover, the corolla cover 24 does not need to be completely closed as shown in FIG. 5. That is, the filling port P1 may be partially protruded from the opening 24 d formed in the central portion of the corolla cover 24.

容器1更具有固定於綑綁具45的被鉤掛具48。在本實施形態中，被鉤掛具48是由形成為環圈狀的繩帶所構成。被鉤掛具48是用以鉤掛在從上方懸吊可撓性容器1之吊掛具7的構件。圖6顯示了相較於被鉤掛具48鉤掛於吊掛具7，從上方懸吊可撓性容器1時的樣態。被鉤掛具48是當填充埠P1容置於花冠蓋24內時，從花冠蓋24之中央部的開口24d朝外部被拉出，鉤掛在吊掛具7。再者，吊掛具7是典型的吊鉤。The container 1 further includes a hooked hanger 48 fixed to the strap 45. In the present embodiment, the hooked harness 48 is composed of a looped belt. The hooked hanger 48 is a member for hanging on a hanger 7 for hanging the flexible container 1 from above. FIG. 6 shows a state in which the flexible container 1 is suspended from above, as compared with the case where the hooked hanger 48 is hooked on the hanger 7. When the filling port P1 is accommodated in the corolla cover 24, the hooked hanger 48 is pulled out from the opening 24 d in the central portion of the corolla cover 24 to the outside, and is hooked on the hanger 7. Moreover, the hanger 7 is a typical hook.

又，如圖6所示，除了被鉤掛具48，固定在外袋2之複數個被鉤掛具35b也被鉤掛在吊掛具7。被鉤掛具35b對應於配置在外袋2的四隅之細長帶狀的構件(以下，稱為框帶)35的上部。更具體而言，4條框帶35的中間部35a以縫固於側表面部23等的態樣固定成沿著外袋2的4面的側表面部23的邊界朝上下方向延伸。框帶35的上部形成為維持環圈狀，並且此成為被鉤掛具35b。另一方面，如圖3及圖4所示，4條框帶35的下部35c沿著底面部22折曲，且朝向底面部22的中央延伸，整體成放射狀配置。下部35c是以縫固等的態樣固定在底面部22。下部35c之最內側的端部未達下部開口22a及蓋5。又，下部35c之最內側的端部也是形成為環圈狀，繩帶36插通於該等環圈的孔。繩帶36是當內容物填充於內袋3內，外袋2的本體部20大略成立方體形狀時，藉由框帶35的下部35c而朝底面部22的四隅拉伸。藉由該張力，繩帶36大致呈正方形展開，藉此，裝有內容物之容器1的底面部22維持平面狀。As shown in FIG. 6, in addition to the hooked hanger 48, a plurality of hooked hangers 35 b fixed to the outer bag 2 are also hooked to the hanger 7. The hooked hanger 35b corresponds to the upper part of a four-slender long belt-shaped member (hereinafter, referred to as a frame belt) 35 arranged in the outer bag 2. More specifically, the middle portion 35 a of the four frame tapes 35 is fixed to the side surface portion 23 and the like so as to be fixed to extend up and down along the boundary of the four surface side surface portions 23 of the outer bag 2. The upper portion of the frame band 35 is formed in a ring shape, and this becomes the hooked hanger 35b. On the other hand, as shown in FIGS. 3 and 4, the lower portions 35 c of the four frame bands 35 are bent along the bottom surface portion 22 and extend toward the center of the bottom surface portion 22, and are arranged radially as a whole. The lower portion 35c is fixed to the bottom surface portion 22 in a state such as sewing. The innermost end portion of the lower portion 35c does not reach the lower opening 22a and the cover 5. In addition, the innermost end portion of the lower portion 35c is also formed into a loop shape, and the string 36 is inserted into the hole of the loop. When the content of the cord 36 is filled in the inner bag 3 and the body portion 20 of the outer bag 2 has a substantially cubic shape, it is stretched toward the four sides of the bottom surface portion 22 by the lower portion 35c of the frame 35. By this tension, the cord 36 is unfolded in a substantially square shape, whereby the bottom surface portion 22 of the container 1 containing the contents is maintained in a flat shape.

Manufacturing method of flexible container with contents>
Next, a method for filling the contents into the empty flexible container 1 prepared as described above will be described. First, the prepared empty container 1 with the upper surface portion 21 facing upward is placed below a device (hereinafter, referred to as a supply device) such as a hopper for supplying contents. Next, the hooked hanger 35b of the outer bag 2 is hooked to a hanger such as a hook of the supply device, and the flexible container 1 is suspended from above. Next, the slider 24c is released, the corolla cover 24 is opened, and the inner cover 4 is also opened, so that the filling port P1 is opened as much as possible in a cylindrical shape. Thereby, the input path R1 is opened largely upward, that is, toward the discharge port for discharging the contents in the supply device. Next, the discharge port of the supply device is inserted into the input path R1. Next, by opening the discharge port of the supply device, the contents are put into the inner bag 3 from the supply device via the input path R1.

在填充內容物後，封閉填充埠P1。具體而言，擰緊填充埠P1，以封閉形成於填充口部31的內側的投入路R1。接著，將綑綁具45以從外側圍繞呈細長的填充埠P1的方式牢牢地纏繞填充埠P1後，再將綑綁具45打結以緊固纏繞狀態。接著，將填充埠P1折疊，使內蓋4載置於其上，進而封閉花冠蓋24。藉此，封閉上部開口21a，填充埠P1容置於花冠蓋24的內側。此時，從花冠蓋24之中央部的開口24d，將固定在綑綁具45之被鉤掛具48拉出到外側。藉由以上，製造裝入內容物的可撓性容器1。After filling the contents, the filling port P1 is closed. Specifically, the filling port P1 is tightened to close the insertion path R1 formed inside the filling port portion 31. Next, the binding device 45 is firmly wound around the filling port P1 so as to surround the elongated filling port P1 from the outside, and then the binding device 45 is tied to tighten the winding state. Then, the filling port P1 is folded, and the inner cover 4 is placed thereon, thereby closing the corolla cover 24. Thereby, the upper opening 21 a is closed, and the filling port P1 is accommodated inside the corolla cover 24. At this time, the hooked tool 48 fixed to the binding tool 45 is pulled out from the opening 24d in the central portion of the corolla cover 24 to the outside. In this way, the flexible container 1 containing the contents is manufactured.

裝有內容物之可撓性容器1保管在適當的保管場所，因應需要而輸送。在輸送時等使可撓性容器1移動時，可載置於托板，並將其以堆高機等的搬送裝置搬運。又，可利用具有吊鉤等之吊掛具的吊車等的搬送裝置。即，藉由在被鉤掛具35b鉤掛在搬送裝置之吊掛具的狀態下驅動搬送裝置，可容易使可撓性容器1移動。The flexible container 1 containing the contents is stored in an appropriate storage place and transported as required. When the flexible container 1 is moved during transportation or the like, the flexible container 1 can be placed on a pallet and carried by a transfer device such as a stacker. Further, a conveyance device such as a crane having a hanger such as a hook can be used. That is, the flexible container 1 can be easily moved by driving the conveying device in a state where the hooked hanger 35b is hooked to the hanger of the conveying device.

＜2-3.可撓性容器的開封方法＞
其次，說明裝有內容物之可撓性容器1的開封方法。首先，將裝有內容物的容器1，以如底面部22向下的準備狀態配置在供給內容物之料斗等的裝置(以下，稱為被供給裝置)的上方。其次，將外袋2之四隅的被鉤掛具35b鉤掛在專用的吊掛裝置(例如，升降機)之吊鉤等的吊掛具7，從上方懸吊可撓性容器1。又，此時，固定於被捲繞在填充埠P1之綑綁具45的被鉤掛具48也鉤掛在吊掛裝置的吊掛具7。然後，作業者站在可撓性容器1的側方，手伸往底面部22的下方，拆下蓋5。再者，藉由蓋5之如上述的構成，此時，蓋5可以一個動作（one touch）拆下。在蓋5拆下同時，被綑綁具40綁縛的狀態的排出埠P2藉由排出埠P2的自重而從底面部22自動地如圖2所示垂下。<2-3. Unsealing method for flexible container>
Next, a method for unsealing the flexible container 1 containing the contents will be described. First, the container 1 containing the contents is placed above a device (hereinafter, referred to as a supplied device) such as a hopper for supplying contents in a prepared state such as the bottom surface portion 22 downward. Next, the flexible container 1 is suspended from above by hooking the hooked hanger 35b of the outer bag 2 to a hanger 7 such as a hook of a dedicated hanger (for example, an elevator). At this time, the hooked hanger 48 fixed to the binding tool 45 wound around the filling port P1 is also hooked to the hanger 7 of the hanging device. Then, the worker stands on the side of the flexible container 1 and extends his hand under the bottom surface portion 22 to remove the cover 5. Furthermore, with the configuration of the cover 5 as described above, at this time, the cover 5 can be removed with one touch. At the same time as the cover 5 is removed, the discharge port P2 in a state bound by the binding tool 40 is automatically dropped from the bottom surface portion 22 as shown in FIG. 2 by the weight of the discharge port P2.

接著，作業者站在可撓性容器1的側方，就此將手伸往可撓性容器1的下方，解開垂下之排出埠P2的綑綁具40。再者，藉由綑綁具40之如上述的構成，此時，綑綁具40可以一個動作解開。藉此，下端向上地折疊之排出埠P2因為自重而該下端向下地筆直延伸。其結果是，排出路R2朝向下方，即，朝向被供給裝置中接收內容物的投入口而將之大幅地打開，內容物經由排出路R2而往被供給裝置投入。Next, the operator stands on the side of the flexible container 1 and then puts his hand under the flexible container 1 to release the hanging tool 40 of the hanging discharge port P2. Furthermore, with the configuration of the binding device 40 as described above, at this time, the binding device 40 can be released in one action. As a result, the discharge port P2 with its lower end folded upwardly extends straight downward due to its own weight. As a result, the discharge path R2 faces downward, that is, opens toward the feeding port for receiving the contents in the device to be supplied, and the contents are opened into the device to be supplied through the discharge path R2.

圖7是顯示沒有將被鉤掛具48鉤掛在吊掛具7，而是藉由吊掛具將可撓性容器1從上方懸吊的樣態的圖。從圖6及圖7比較時可知，圖7之例中，因內容物的重量而內袋3往下方拉伸上表面部21，因此內袋3往下沈。特別是，當內容物漸漸減少時，內袋3的膨脹會漸漸消失，內袋3更往上下方向變長，因此內袋3的下端益發往下方垂下。此時，根據被供給裝置與容器1的位置關係，內袋3的下部塞入被供給裝置的投入口，會妨礙內容物的排出。因此，如圖6所示，宜先藉將被鉤掛具48鉤掛在吊掛具，使內袋3的下端不會往上下方垂下。FIG. 7 is a view showing a state in which the flexible container 1 is suspended from above by the hanger without being hooked on the hanger 7. As can be seen from a comparison between FIG. 6 and FIG. 7, in the example of FIG. 7, the inner bag 3 stretches the upper surface portion 21 downward due to the weight of the contents, so the inner bag 3 sinks. In particular, when the contents gradually decrease, the expansion of the inner bag 3 gradually disappears, and the inner bag 3 becomes longer in the up-down direction. Therefore, the lower end of the inner bag 3 is prone to hang down. At this time, according to the positional relationship between the supplied device and the container 1, the lower portion of the inner bag 3 is inserted into the input port of the supplied device, which prevents the contents from being discharged. Therefore, as shown in FIG. 6, it is preferable to first hook the hooked hanger 48 to the hanger so that the lower end of the inner bag 3 does not hang down and up.

＜3.變形例＞
以上，就本發明之一實施形態進行說明，但本發明並不限定於上述實施形態，只要不脫離其主旨，可為各種變更。又，以下之變形例的要旨可適宜組合。＜ 3. Modifications ＞
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, Various changes are possible as long as it does not deviate from the meaning. The gist of the following modifications can be appropriately combined.

＜3-1＞
上述實施形態中，外袋2的本體部20作成方筒狀，但不限定於此，例如，亦可作為圓筒狀。<3-1>
In the above embodiment, the main body portion 20 of the outer bag 2 is formed in a rectangular tube shape, but it is not limited to this, and may be, for example, a cylindrical shape.

＜3-2＞
開口21a、22a的形狀沒有特別限定，在上述實施形態中為圓形，但亦可為例如楕圓形、四角形等。再者，若變更開口21a、22a的形狀，宜配合開口的形狀而填充口蓋25、排出口蓋26的形狀也適宜變更為同樣的形狀。又，蓋5的形狀也沒有特別限定，亦可為例如圓形、楕圓形等。＜ 3-2 ＞
The shape of the openings 21a and 22a is not particularly limited, and is circular in the above embodiment, but may be, for example, a round shape, a quadrangular shape, or the like. In addition, if the shape of the openings 21a and 22a is changed, it is preferable to change the shapes of the filling mouth cover 25 and the discharge port cover 26 to the same shape in accordance with the shape of the opening. The shape of the cover 5 is not particularly limited, and may be, for example, a circular shape or a round shape.

＜3-3＞
綑綁具40的構成不限於上述者，亦可與綑綁具45同樣地，可為單為繩帶41而不具有黏扣42、43，亦可為可固定捲繞狀態之附有鈕扣(包含子母扣snap button)的繩帶41。再者，若為單純的繩帶，可與綑綁具45同樣地作成蝴蝶結等。＜ 3-3 ＞
The structure of the binding device 40 is not limited to the above, and may be the same as the binding device 45, and may be a string 41 alone without the hooks 42, 43 or a button (including a child) that can fix the winding state. Female button snap button 41). In addition, if it is a simple string, a bow etc. can be made similarly to the binding tool 45.

又，舉其他例，綑綁具40亦可為如圖8所示之扣合具70。扣合具70包含1條繩帶71、及供繩帶71的兩端平行通過的滑動件72。藉由繩帶71與滑動件72，形成有環圈，於該環圈***被綑綁的排出埠P2。滑動件72構成為可沿著繩帶71、71移動。又，於滑動件72，安裝有用以鎖固成無法沿繩帶71、71移動的狀態的鎖固構件73。於該鎖固構件73的端部安裝有繩帶74。接著，當拉伸繩帶74時，鎖固構件73移動，解除鎖固，而滑動件72可相對繩帶71移動。再者，在鎖固解除時，鎖固構件73會與滑動件72結合而不會由滑動件72脫落。因此，當更拉伸繩帶74，經由鎖固構件73而拉伸滑動件72時，由繩帶71與滑動件72形成的環圈會擴大。因此，繩帶71由排出埠P2脫落，解開綑綁。再者，較佳的是，繩帶71與上述的綑綁具40同樣地先固定在外袋2，以在可撓性容器1開封時，解開綑綁後，扣合具70不會被投入到被供給裝置等中。Also, for another example, the binding tool 40 may be a fastening tool 70 as shown in FIG. 8. The fastening device 70 includes a rope 71 and a slider 72 through which both ends of the rope 71 pass in parallel. A loop is formed by the cord 71 and the slider 72, and the bundled discharge port P2 is inserted into the loop. The slider 72 is configured to be movable along the cords 71 and 71. Furthermore, a locking member 73 is attached to the slider 72 so as to be locked in a state where it cannot move along the cords 71 and 71. A rope 74 is attached to an end of the locking member 73. Then, when the string 74 is stretched, the locking member 73 moves to release the lock, and the slider 72 can move relative to the string 71. Moreover, when the lock is released, the lock member 73 is coupled to the slider 72 and does not fall off by the slider 72. Therefore, when the string 74 is further stretched and the slider 72 is stretched through the locking member 73, the loop formed by the string 71 and the slider 72 is enlarged. Therefore, the rope 71 is detached from the discharge port P2, and the binding is released. Furthermore, it is preferable that the strap 71 is first fixed to the outer bag 2 in the same manner as the binding device 40 described above, so that when the flexible container 1 is unsealed, the fastening device 70 is not put into the container after the binding is released. Supply device, etc.

同樣地，綑綁具45的構成也不限於上述，例如，亦可與綑綁具40同樣地，令綑綁具45為附有黏扣的繩帶，亦可為附有可固定捲繞狀態的鈕扣(包含子母扣)的繩帶41，亦可為如圖8所示之扣合具70。Similarly, the configuration of the binding device 45 is not limited to the above. For example, similar to the binding device 40, the binding device 45 may be a string with a hook and loop, or a button with a fixed winding state ( The strap 41 including the daughter-in-law buckle may also be a buckle 70 as shown in FIG. 8.

又，綑綁具40、45之至少一者不需要分別固定於填充口蓋25、排出口蓋26，可作成獨立於外袋2及內袋3的構件。In addition, at least one of the bindings 40 and 45 does not need to be fixed to the filling opening cover 25 and the discharge opening cover 26 respectively, and can be made a separate member from the outer bag 2 and the inner bag 3.

＜3-4＞
被鉤掛具48亦可不是固定在綑綁具45，而是固定在填充口蓋25、花冠蓋24、內蓋4或上表面部21的中央附近等外袋2之上部的中央附近的部位。此時也可在將被鉤掛具48鉤掛於吊掛具，懸吊容器1時，防止內袋3的下端固定往上下方垂下。<3-4>
The hooked hanger 48 may not be fixed to the binding tool 45, but may be fixed to a portion near the center of the upper part of the outer bag 2 such as the filling mouth cover 25, the corolla cover 24, the inner cover 4, or the center of the upper surface portion 21. At this time, when the hooked hanger 48 is hooked to the hanger, and the container 1 is suspended, the lower end of the inner bag 3 can be prevented from hanging down and up and down.

＜3-5＞
將蓋5安裝於底面部22的方法不限定於使用黏扣的方法，例如，亦可以鈕扣固定兩者。例如，亦可將鈕扣安裝於底面部22及蓋5的其中一者，並於另一者形成鈕扣孔。又，亦可於底面部22及蓋5的其中一者安裝子母扣的凸件，並於另一者安裝凹件。<3-5>
The method of attaching the cover 5 to the bottom surface portion 22 is not limited to a method using a hook and loop, and for example, both may be fixed by buttons. For example, a button may be mounted on one of the bottom surface portion 22 and the cover 5, and a button hole may be formed in the other. In addition, the convex part of the daughter-in-law buckle may be attached to one of the bottom surface part 22 and the cover 5, and the concave part may be attached to the other.

＜3-6＞
上述實施形態中，將排出埠P2擰緊以封閉排出路R2後，將變細長的排出埠P2朝一方折返，該折返且擰緊之狀態是藉由綑綁具40固定。然而，亦可將大致平面狀的排出埠P2朝一方折返後，將折疊成2折(或者3折以上)的排出埠P2擰緊，利用綑綁具40固定該業經折返且擰緊的狀態，以封閉排出路R2。＜ 3-6 ＞
In the above embodiment, after the discharge port P2 is tightened to close the discharge path R2, the elongated discharge port P2 is folded back to one side, and the folded and tightened state is fixed by the binding tool 40. However, after the substantially flat discharge port P2 is turned back to one side, the discharge port P2 folded into two folds (or more than three folds) can be tightened, and the folded and screwed state of the industry can be fixed by the binding tool 40 to close the discharge. Road R2.

或者，如圖9所示，亦可以在擰緊排出埠P2在封閉排出路R2後，不折返排出埠P2，而是利用綑綁具40綁縛排出埠P2，以保持排出埠P2被擰緊的狀態。接著，其後亦可視需要將排出埠P2折返後，將排出埠P2收納在蓋5與底面部22之間。Alternatively, as shown in FIG. 9, after the discharge port P2 is tightened and the discharge path R2 is closed, the discharge port P2 is not folded back, but the discharge port P2 is bound by the binding tool 40 to keep the discharge port P2 tightened. Then, after the discharge port P2 is folded back as necessary, the discharge port P2 is stored between the cover 5 and the bottom surface portion 22.
