  The container according to the present invention includes a base member and a plurality of containers attached to the base member. In this embodiment, as shown in FIGS. 1 to 4, the container 1 includes a plate-like base member 3 and a plurality of containers attached to the base member 3 (in this embodiment, two containers are provided). 20).

  As shown in FIG. 1, the base member 3 has a rectangular and thin plate-like appearance, and is integrally formed of a synthetic resin such as polyethylene or polypropylene. In the base member 3, it is possible to pour out the welded portion 5 that allows a plurality of containers 20 in which the stored items are stored to be individually mounted, and the stored items in each container 20 mounted on the welded portion 5. A spout 7 is integrally formed.

  The weld portion 5 is formed so as to protrude toward the back surface side of the base member 3, has a cross section formed in a boat shape, and a surface on which a flexible synthetic resin sheet (sheet member) constituting the container 20 is welded. It has a shape. In the welded portion 5, a communication hole 6 is formed through which the contents stored in the container 20 pass. The communication hole is connected to a spout 7 formed on the surface side of the base member 3.

  Further, as shown in FIG. 1, the weld portion 5 is arranged in series along the longitudinal direction (arrow X direction) with respect to the rectangular base member 3, and is a container formed as described later. 20 can be easily manufactured.

  The spout 7 according to this embodiment is configured as a hole that opens on the surface of the base member 3, and each spout 7 is connected to a communication hole 6 formed in the welded portion 5. In this case, the opening of the spout 7 is formed flush with the surface of the base member 3. For example, an elastic body such as rubber is enclosed in the opening, and the thin film 7 a is covered in the opening on the surface. It can be worn and configured.

  A flexible synthetic resin sheet for constituting the container 20 is welded to the weld surface of the weld portion 5. Specifically, the container 20 to be attached to each welded portion 5 is prepared by stacking two flexible synthetic resin sheets in advance and welding the periphery thereof, and welding this to the surface of each welded portion. Is done.

  Here, with reference to FIGS. 5 to 8, a manufacturing process for creating the container 1 having the above-described configuration will be specifically described.

  A plurality of support holes 8 are formed on the surface of the base member 3. As shown in FIG. 5, when the synthetic resin sheets 21 </ b> A and 21 </ b> B in which the plurality of support holes 8 are overlapped and welded to each other are welded to the welding surface of the welding portion 5, The base member 3 is positioned and held by engaging with the protruding fixing jig 51.

  In this case, the two flexible synthetic resin sheets 21A and 21B have a surrounding (vertical) that defines the inner space of the container 20 except for the surrounding area, specifically, the upper side 21d shown in white in FIG. The side 21a and the bottom side 21b) are welded in advance by a heat bar. In addition, about the base part 21c used between the adjacent containers 20, you may weld beforehand and it is not necessary to weld. Moreover, about the process of welding the circumference | surroundings of the two synthetic resin sheets 21A and 21B which were piled up, either a vertical side or a horizontal side may be welded first, and you may weld at once.

  The two synthetic resin sheets 21A and 21B welded in this way are in a state in which the upper side portion is opened (a state in which a peripheral region other than the adjacent welded portion 5 is interposed is welded). A synthetic resin sheet is placed on the base member 3 set on the fixing jig 51 on the adjacent welded portion 5, and is disposed so as to interpose the welded portion (a bag body on which a plurality of containers 20 are formed). Set). FIG. 5 shows a state in which the bag body is set, and such a bag body setting may be performed mechanically or manually.

  Next, the region of the upper side 21d shown in FIG. 5 (this region is in series along the direction of the arrow X in FIG. 1) is formed by a pair of heat bars 53 and 54 as shown in FIG. The pressing process is performed in a direction Y orthogonal to the arrow X direction in FIG. In this case, concave surfaces 53a and 54a are formed on the opposing surfaces of the heat bars 53 and 54 so as to press-contact the surface of each welded portion 5, and the other heat bars are indicated by arrows Y. Even if it approaches the direction, it is a flat surface so as not to contact the opponent's heat bar. For this reason, as shown in FIG.6 (b), when both the heat bars 53 and 54 are pressed mutually in the arrow Y direction, the surface of each welding part 5 will be welded by heat, and the area | region other than that will be unwelded ( (Refer FIG.6 (b) and (c)).

  Next, the region of the upper side 21d other than the welded portion 5 is pressed in the arrow Y direction by a pair of heat bars 55 and 56 as shown in FIG. In this case, the opposing surfaces of the heat bars 55 and 56 are formed with curved surfaces 55a and 56a that are recessed away from the surface of the welded portions 5, and the other heat bars are in the direction of the arrow Y. When approaching, it is a flat surface that is in close contact with the opponent's heat bar. Therefore, as shown in FIG. 7B, when the heat bars 55 and 56 are pressed against each other in the arrow Y direction, the upper side 21d other than the surface of each welded portion 5 is welded (FIGS. 7B and 7C). )reference).

  Next, as shown in FIGS. 8A and 8B, the region of the upper side 21d welded as described above is pressed by the cooling bars 57 and 58 and cooled. In this case, concave surfaces 57a, 58a are formed on the opposing surfaces of the cooling bars 57, 58 so as to press-contact the surface of each welded portion 5, and other portions are also in close contact with the other cooling bar. It is a flat surface. For this reason, as shown in FIG.8 (b), when both the cooling bars 57 and 58 are pressed mutually in the arrow Y direction, the area | region of the upper side 21d welded by the above-mentioned pressing process will be cooled.

  When welding the region of the upper side 21d, as described above, the portion of the welded portion 5 may be welded first, and then the portion other than the welded portion 5 may be welded, or a single press The region of the upper side 21d may be welded in the process.

  Thereby, it becomes possible to manufacture the container 1 provided with the some container 20 as shown in FIG.2 and FIG.3 at once by a simple welding process.

  In addition, as described above, the container 20 attached to the welded portion 5 has a configuration in which two synthetic resin sheets 21A and 21B are overlapped and the peripheral region is welded. You may be comprised in what is called the self-solid form (container in which the bottom face and the side surface were formed) which piled up the synthetic resin sheet.

  And it is possible, for example, to insert the injection needle into the spout 7 and fill the internal space of each container 20 thus configured. In this case, when the injection needle is inserted into the spout 7 and pulled out, the inserted portion is blocked by the pressing force of the elastic body enclosed inside. Of course, in addition to this, a part of the periphery of the synthetic resin sheet may be left in an unwelded state, and after filling the contents, the part may be welded, or the synthetic resin sheet in a state filled with the contents in advance. May be welded to the welded portion 5.

  Moreover, in the structure of this embodiment, the thin-walled part 9 which enables it to bend itself is formed in the base member 3 formed in the said plate shape. The thin-walled portion 9 is formed on one side surface (side surface 3a, 3b side) by forming a groove 9a in a direction perpendicular to the X direction with respect to the base member 3. In this case, the thin-walled portion 9b is formed on the other side surface when molding, but the thin-walled portion 9b is a portion that is broken when the base member 3 is bent. Therefore, the thickness of the thin-walled portion 9b may be about 0.3 to 0.4 mm so that it can be easily broken. The thin-walled portion 9 has a thickness that does not break even when bent, for example, 0 .7 to 1.0 mm is sufficient. Then, as shown in FIG. 1A, the side surfaces 3a and 3b of the base member 3 are brought into close contact with each other by bending the base member 3 approximately 180 ° in the direction of the arrow through the thin-walled portion 9. It is possible to change the arrangement mode of the container 20 attached to the welded portion 5 from the serial body shown in FIG. 2 to the parallel state shown in FIG. It has become.

It can be configured by the locking hole 12. As a result, when the base member 3 is bent approximately 180 ° in the direction of the arrow in FIG. 1A with the portion of the thin-walled portion 9 as a fulcrum and the one side surfaces 3a and 3b are brought into close contact with each other, a pair of claw members 11 are provided. Spreads into the corresponding locking hole 12 and the parallel state of the containers 20 is maintained as shown in FIG.

  The fixing portion and the engaging portion can be variously modified other than the claw member 11 and the locking hole 12 as shown in FIG. For example, a configuration in which a flange or a protrusion is provided on one of the side surfaces 3a and 3b and a long groove or a recess in which the flange is inserted is provided on the other surface may be employed. .

  In the container 1 configured as described above, since the adjacent welded portions 5 are arranged in series with the base member 3, it is possible to simultaneously manufacture a plurality of containers 20 in a single welding step. It becomes. That is, since a synthetic resin sheet can be welded to a plurality of welded portions 5 at the same time in a single welding step, the manufacturing efficiency of a container having a plurality of containers can be improved, and the cost can be reduced. In this case, for example, after attaching and forming each container 20, it is possible to form individual containers for each container by cutting the above-mentioned thin-walled portion 9, so that the manufacturing efficiency is improved. Become.

  Moreover, since the container 1 comprised as mentioned above is provided with the some container 20 with respect to the one base member 3, and the spout 7 is formed corresponding to each container, several In a case where necessary items are poured out from the stored items and used, the stored items can be grouped in advance. Therefore, it is not necessary to arrange a plurality of containers or to convey them individually, so that convenience in handling can be improved.

  In addition, since the container 1 containing a plurality of items for each container 20 can be attached to a casing such as an external device (including a casing attached to and detached from the external device), the installation of the casing is possible. It is possible to reduce the number and space of the volume, and to reduce the size of the external device.

  Furthermore, since the container can be changed from a serial body to a parallel state by bending the thin-walled portion 9, it is possible to set the container 1 in an optimal arrangement mode according to conveyance, setting of an external device, and the like.
