  With the above-described conventional container, two different liquids and gels can be accommodated in one container, and the use of these two liquids and gels can be simplified.

  However, in the container using the partition member as described above, at least a step of assembling the partition member inside the container main body and a step of bonding the partition member in a liquid-tight state in the container main body are necessary, and It is necessary to produce the container body and the partition member separately.

  Therefore, when producing a multi-chamber container, the production process becomes complicated, and coupled with the large number of parts, this causes a decrease in productivity and an increase in production cost.

  Moreover, in the technique of constructing a multi-chamber container by assembling two containers, it is necessary to form irregularities and fit them together in order to eliminate the displacement of both containers after being integrated. This will cause a decrease in productivity.

  The present invention has been made in view of such conventional problems, and it is intended to provide a multi-chamber container that can increase the productivity by reducing the number of components as much as possible, and thus can reduce the production cost. Let it be a solution issue.

  The multi-chamber container according to claim 1 of the present invention includes a container body provided with at least two storage chambers, and an openable / closable discharge port attached to the container body and communicated with each of the storage chambers. The container body has one storage chamber formed by curving a flexible sheet and adhering one side edge to the entire back surface of the sheet over the entire length. A chamber is formed by adhering the other side edge of the sheet to the outer surface of the storage chamber formed in advance, and the cap is mounted so as to cover one end of each of the storage chambers. The other end of each storage chamber is sealed by overlapping and bonding the side walls of each storage chamber.

  With such a configuration, a multi-chamber container having at least two storage chambers can be formed by a single sheet.

  As a result, the number of parts constituting the container can be minimized to reduce the production cost, and the production process can be simplified to increase the productivity.

  And when adhering one side edge of the sheet to the back surface side of the sheet, the surface side of the one side edge is adhered in contact with the back surface, or the back surface side of the one side edge is bonded. Adhesion is performed in contact with the back surface.

  Thus, by changing the adhesive surface of one side edge, the cross-sectional shape of the accommodation chamber to be formed can be changed, and thereby the design effect of the container body can be changed.

  According to the present invention, in a multi-chamber container, the number of parts can be reduced as much as possible, thereby suppressing the production cost and simplifying the production process to improve productivity.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a multi-chamber container according to this embodiment, which is flexible as a whole, and has a container body 2 having two storage chambers 3 and 4 inside as shown in FIG. And an openable / closable cap 5 attached to one end of the container body 2 and attached to cover one end of each of the storage chambers 3 and 4.

  If these details are demonstrated, the said container main body 2 is comprised by the rectangular-shaped sheet | seat S (refer FIG. 3) which has flexibility, such as a synthetic resin, and this sheet | seat S is shown by the arrow in FIG. As shown in FIG. 4, the first storage chamber 3 in the storage chamber is formed by adhering the one side edge Sa to the back surface of the sheet S over the entire length, as shown in FIG. By curving the other side edge Sb of the sheet S as shown by an arrow in FIG. 4 and adhering to the outer surface of the first storage chamber 3 formed previously as shown in FIG. A second storage chamber 4 which is a storage chamber is formed.

  As shown in FIG. 5, the cap 5 mounted so as to cover one end of each of the storage chambers 3 and 4 is curvedly formed at a portion mounted on the container main body 2 as shown in FIG. A mounting groove 5a having substantially the same shape as the curved shape is formed, and one end of the container body 2 is fitted into the mounting groove 5a, and adhesion by an adhesive, fusion by heat, or The container body 2 is integrated in a liquid-tight state by an adhering means such as fusion using ultrasonic waves.

  Then, the other end of the container body 2 is deformed to be flattened as shown in FIG. 7 by being deformed so as to be crushed inward in the radial direction as indicated by an arrow in FIG. The range of the predetermined width from the one end edge is sealed in a liquid-tight state by an adhering means such as adhesion using an adhesive, heat fusion, or ultrasonic fusion as described above. .

  As a result, as shown in FIGS. 1, 2, and 8, a multi-chamber container 1 is constructed in which one end is closed by the cap 5 and the other end is sealed.

  The container main body 2 has the first and second storage chambers 3 and 4 partitioned by a partition wall 6 formed of a part of the curved sheet S.

  As shown in FIG. 2, the cap 5 includes a mounting portion 7 in which the mounting groove 5 a is formed and a lid portion 8 that is rotatably connected to the mounting portion 7.

  The mounting portion 7 includes a top plate portion 9 positioned so as to cover one end portion of the container body 2, and the top plate portion 9 has two discharges communicated with the storage chambers 3 and 4, respectively. The outlets 10 and 11 are formed through.

  The lid portion 8 constituting the cap 5 is integrally connected to the mounting portion 7 via a hinge H formed continuously to the mounting portion 7, and overlaps the mounting portion 7. At the closed position, two closing plugs 12 and 13 are provided so as to fit into the discharge ports 10 and 11 and close them.

  The multi-chamber container 1 according to the present embodiment configured as described above is formed by curving a single sheet S and bonding a pair of side edges Sa and Sb to the surface of the sheet S. A pair of storage chambers 3 and 4 are formed, and the cap 5 is attached to one end of the storage chamber 3 and the container 5 is filled with an object from the opening at the other end.
