Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a liquid container for storing a liquid, and more particularly to a liquid container suitable for storing a viscous liquid such as ink used in an ink self-priming copying machine.

[0002]

[Prior art]

 An example of this type of liquid container is disclosed in Japanese Utility Model Application Laid-Open No. 64-17926 of the present applicant. This liquid container comprises a rectangular reference body having a relatively rigid rigidity with a spout protruding from a lower edge of an outer surface, and a flexible bag having one end joined to a cylindrical frame provided on a peripheral portion of the reference body. It is composed of the body. For example, heat sealing is applied to the joint between the cylindrical frame portion of the reference body and the flexible bag body.

The liquid container thus configured is usually used in a state of being housed in a cardboard box. In this case, the liquid containers are positioned relative to each other when the reference body coincides with one side of the box, and the spout is projected outside through a hole provided on one side of the box. . Therefore, if the liquid inlet is connected to this spout, the liquid filled in the liquid container can be sucked out.

[0004]

[Problems to be solved by the invention]

 In the liquid container described above, the reference body forms one surface of the liquid container. Therefore, this reference body needs to be in the form of a plate having a predetermined size. In addition, the reference frame has the essential configuration of the above-described tubular frame in order to obtain a sufficient bonding force with the flexible bag.

[0005] As a result, when manufacturing the liquid container, it is necessary to prepare a reference member having a plate shape on all five sides, that is, a reference member requiring an extremely large number of materials. The need for a body would result in a significant increase in manufacturing costs.

Further, in the liquid container, prior to joining the reference body and the flexible bag, an operation of fitting the opening of the flexible bag into the cylindrical frame of the reference body is required. Becomes Such a fitting operation can be easily performed when both are members having rigidity. However, in the above liquid container, since the bag body has flexibility, and the opening shape is arbitrarily deformed when the bag body comes into contact with the cylindrical frame portion which is a rigid body, Work becomes extremely complicated.

[0007] In view of the above circumstances, it is an object of the present invention to provide a liquid container that can reduce manufacturing costs and facilitate manufacturing operations.

[0008]

[Means for Solving the Problems]

 In the present invention, a bag body having flexibility and filled with a liquid therein, a reference body formed in a rectangular frame shape with a relatively rigid material and joined to an inner surface of the bag body, And a spout formed integrally with the reference body and protruding out of the bag body to form a liquid container.

[0009]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the drawings showing one embodiment. FIG. 1 shows an embodiment of the liquid container according to the present invention. The liquid container 1 exemplified here is particularly suitable for containing a viscous liquid such as ink used in an ink self-priming copying machine, and includes a bag body 10 and a reference body 20. ing.

The bag body 10 is made of a translucent plastic thin flexible sheet material, and has a sealed bag shape.

On the other hand, the reference body 20 is formed by integrally molding a frame-shaped portion 21 and a baffle plate portion 22 with relatively rigid plastic. The frame portion 21 is a plate-like member having a rectangular frame shape, and has a pair of reinforcing ribs 23 inside the frame. The reinforcing ribs 23 extend so as to be parallel to each other inside the frame, and both ends of the reinforcing ribs 23 connect the both ends of the frame portion 21 to each other. The baffle plate portion 22 is a plate-like member projecting perpendicularly from the bottom surface of the frame-like portion 21 and connects the pair of reinforcing ribs 23 to each other.

The reference body 20 has a spout 24 at one corner of the frame 21. The spout 24 has a cylindrical shape having a screw portion 24a at the distal end and a flange portion 25 at the proximal end. The spout 24 protrudes perpendicularly from the upper surface of the frame portion 21 by being connected to the frame portion 21 via the flange portion 25. In addition, in the spout 24, the lid 30 can be detachably attached to the screw portion 24a described above.

When manufacturing the liquid container 1 having the above-described configuration, first, as shown in FIG. 2, a reference body 20 including a frame portion 21, a reinforcing rib 23, and a baffle plate portion 22, A tubular sheet material prepared by integrally molding the spout 24 and cutting a thin flexible tube of translucent plastic formed into a long length by the inflation method into an appropriate length. Prepare 10 '. The cylindrical sheet material 10 'is provided with an insertion hole 11 through which the spout 24 can be inserted. As shown in FIG. 2 (b), the flexible tube that is cut to obtain the tubular sheet material 10 'has a pair of gussets (gores) 10a, 10a that are turned inward, and after cutting, the pair of gussets (gores) 10a. When the gussets 10a, 10a are stretched and straightened, it is preferable to use a gusset that becomes a square tube corresponding to the outer shape of the reference body 20. This is because the tubular sheet material 10 'can be easily formed into a rectangular bag by this. Here, the reference body 20 is a plate-like member having a rectangular frame shape as described above. Therefore, in the case of manufacturing this, the amount of material is extremely small as compared with the conventional one, so that the manufacturing cost can be greatly reduced and the weight can be reduced.

Next, the reference body 20 is applied to the inner peripheral surface of the tubular sheet material 10 ′ with the spout 24 protruding from the above-described insertion hole 11, and then the flange portion 25 of the spout 24 and the reference body The reference body 20 and the peripheral surface of the bag body 10 constitute one surface of the liquid container 1 by joining the respective 20 to the tubular sheet material 10 ′. In this case, at the time of joining the tubular sheet material 10 'and the reference body 20, it is not necessary to perform an operation of fitting them together, so that the operation can be easily performed. Further, since the reference body 20 is joined to the inner peripheral surface of the tubular sheet material 10 ', the tubular sheet material 10' is not provided without providing a tubular frame around it as in the conventional one. And a sufficient joining force can be secured between them. In addition, heat sealing may be applied to the joining between the flange portion 25 of the spout 24 and the tubular sheet material 10 'and the joining between the reference body 20 and the tubular sheet material 10'.

Next, from the state described above, one end of the tubular sheet material 10 ′ is closed. Furthermore, if the inside of the tubular sheet material 10 'is filled with a liquid, for example, ink, and finally the other end of the tubular sheet material 10' is closed, the tubular sheet material 10 'becomes square. A hexahedral sealed bag 10 is obtained, and the liquid container 1 in which the bag 10 is filled with ink is completed. Even when both ends of the tubular sheet material 10 'are closed, heat sealing may be applied to each.

The liquid container 1 thus configured is housed in a cardboard box 40, for example, as shown in FIG. 3, and is installed at a predetermined location of an ink self-priming copying machine. In this case, as shown in FIG. 4A, the liquid containers 1 are positioned relative to each other when the reference body 20 matches one side of the box 40, and further provided on one side of the box 40. The spout 24 protrudes from the hole 41 to the outside. Therefore, if the ink inlet is connected to the spout 24 after the lid 30 is removed from the spout 24, the ink filled in the liquid container 1 will be sucked out to the printing press.

In this case, when the ink filled in the liquid container 1 is sucked out from the spout 24, the bag body 10 is easily deformed sequentially in accordance with the decrease of the ink, and as shown in FIG. When the remaining amount of the ink filled in the liquid container 1 becomes small, the flexible bag body 10 is deformed so as to stick to the reference body 20. However, in the liquid container 1, since the baffle plate 22 is provided on the bottom surface of the reference member 20, it is possible to prevent the bag 10 from blocking the spout 24 and to completely fill the filled ink. It can be supplied to printing presses.

As described above, in the liquid container 1, the reference body 20 is bonded to the inner peripheral surface of the bag body 10, and the reference body 20 forms one surface of the liquid container 1 together with the inner peripheral surface of the bag body 10. Therefore, it can be formed in a frame shape. Moreover, since the reference body 20 is joined to the inner peripheral surface of the bag body 10, a sufficient joining force with the bag body 10 is secured without providing a cylindrical frame portion around the conventional body. Will be able to do so. As a result, according to the liquid container 1, it is possible to reduce the manufacturing cost and to reduce the weight while securing desired functions.

In addition, since there is no need to perform an operation of fitting the bag body 10 and the reference body 20 when joining them, the manufacturing operation can be easily performed.

In the above-described embodiment, the reference body 20 having the pair of reinforcing ribs 23 and the baffle plate portion 22 that are parallel to the frame portion 21 is illustrated. It is not limited to them.

For example, as shown in FIG. 5A, the reference body 20 may be constituted only by the frame portion 21. Further, as shown in FIGS. 5B and 5C, the frame 20 is provided with only the diagonally pointed X-shaped or cross-shaped reinforcing ribs 23 to form the reference body 20. As shown in (d) and (e), it is also possible to form the reference body 20 by providing only the baffle plate portion 22 on the frame portion 21.

Further, in the above-described embodiment, the liquid container 1 is used in a state of being housed inside the box 40, but the box 40 is not necessarily required. Further, as an example of the liquid to be filled into the inside, ink used in an ink self-priming copying machine is exemplified. However, any other liquid can be used as long as it is a liquid. In this case, the liquid does not necessarily have to be viscous. In addition, when taking out the filled liquid, it is not always necessary to connect the suction port, and it is of course possible to simply pour the liquid from the spout 24 from which the lid 30 is removed.

Further, in the above-described embodiment, one end of the tubular sheet material 10 ′ is closed, and then the liquid is filled and then the other end is closed. After closing both ends of the sheet material 10 ′, the inside of the bag body 10 may be filled with liquid through the spout 24.

[Effect of the invention]

 As described above, according to the present invention, the reference body is joined to the inner surface of the bag body, and the reference body forms one surface of the liquid container together with the flexible bag body. It becomes possible to form in the shape. Moreover, since the reference body is bonded to the inner surface of the bag body, it is possible to sufficiently secure the bonding force with the flexible bag body without providing a cylindrical frame portion around the reference body as before. become. Therefore, according to the present invention, it is possible to reduce the manufacturing cost and to reduce the weight while securing the desired function in the liquid container. Furthermore, the work of fitting the bag body and the reference body when they are joined is not required, and the manufacturing work can be facilitated.
