The bodies 1) can be connected by aligning the convex portions 12 and the concave portions 13, butting them against each other, and pressing them together.

The fitting connection portion 11 of the lid body 1 is preferably made of a deformable and relatively soft synthetic resin material.

By increasing the strength of the fitting between the convex part 12 and the concave part 13 of the fitting connection part 11 (for example, by making the undercut parts 12a and 13a larger or by using a harder synthetic resin material), it is possible to , even when tensile force, bending force, or twisting force in the direction of the central axis is applied, the containers are difficult to separate from each other, and the connecting and separating operations of the containers are not complicated, making it possible to create a connected container that is easy to use. can.

The number and shape of the convex portions 12 (undercut portions 12a) and recesses 13 (undercut portions 13a) of the fitting connection portion 11 are not limited to two each or circular shape as in this embodiment, but may be any number or shape. It can be done.

According to this connected container, each container is composed of a container with a lid, and the containers can be used alone or connected, and the contents in the containers can be taken out and used with a single operation. This makes it possible to create a connected container that is easy to use.
Since the fitting connection part 11 has the same shape for the containers to be connected, it is easy to design and manufacture containers with lids, and it is possible to easily store multiple types of items (especially, three or more types). Two types can be selected from the stored containers with lids and used by connecting them.
Furthermore, by increasing the fitting strength of the fitting connection, even when tensile force, bending force, or twisting force is applied to the connected containers in the direction of their central axis, the containers are difficult to separate from each other, and the containers are Connection and separation operations are not complicated, and the connected container can be made easy to use.

FIG. 2 shows a second embodiment of the connecting container of the present invention.
In this connecting container, the fitting connection part 11 includes a convex part 12 having a fan-shaped planar shape with an undercut part 12a formed on the circumferential surface, and a flat surface having an undercut part 13a corresponding to the undercut part 12a formed on the circumferential surface. Concave portions 13 having fan-shaped shapes are provided alternately, and containers (lids 1) to be connected can be connected by aligning the convex portions 12 and concave portions 13, abutting them, and pressing them. I have to.

This fitting connection part 11 can increase the fitting dimension between the convex part 12 and the concave part 13, so even if tensile force, bending force, or twisting force is applied to the connected containers in the direction of their central axes, the containers will not fit together. It is possible to provide a connected container that is difficult to separate, does not complicate the connection and separation operations of the containers, and is easy to use.

Note that the other configurations and functions of the connecting container of this embodiment are the same as those of the connecting container of the first embodiment.

FIG. 3 shows a third embodiment of the connecting container of the present invention.
In this connecting container, the fitting connection part 11 has an upright wall 14 having a semicircular planar shape with an undercut part 14a formed on the circumferential surface, and an undercut part 15a corresponding to the undercut part 14a on the circumferential surface. The vertical walls 15 have a semi-circular planar shape and have a radius of curvature larger than the radius of curvature of the vertical wall 14 by the thickness of the vertical wall 14. The connection can be made by aligning the standing walls 15, butting them against each other, and pressing them against each other.

This fitting connection part 11 allows the fitting dimensions of the vertical walls 14 and 15 to be increased, so even if tensile force, bending force, or twisting force is applied to the connected containers in the direction of their central axes, the containers will not separate from each other. It is possible to provide a connected container that is easy to use, does not make connection and separation operations complicated, and is easy to use.

The number and shape of the vertical walls 14 and 15 of the fitting connection portion 11 are not limited to one each or the circular shape of this embodiment, but as in the modification of the third embodiment shown in FIGS. 4 and 5, They can be made into any number or shape (including columnar standing walls and stepped walls).

6 and 7 show a fourth embodiment of the connecting container of the present invention.
In this connecting container, the fitting connection part 11 includes a vertical wall 14 having a semi-circular planar shape with a fly screw-shaped undercut part 14a formed on the circumferential surface, and a fly screw thread corresponding to the undercut part 14a on the circumferential surface. The planar shape of the undercut portion 15a is a semicircular arc, and the radius of curvature is larger than the radius of curvature of the standing wall 14 (when the containers (lids 1) are connected to each other, the outer peripheral surface of the standing wall 14 and (not in contact with the inner peripheral surface of the vertical wall 15) are provided alternately, and the containers (lids 1) to be connected are aligned and butted against each other by aligning the vertical walls 14 and 15, and the containers (lids 1) to be connected are The lid bodies 1 are moved relative to each other in a plane perpendicular to the central axis of the body 1 (including the case where the lid bodies 1 are moved by a small distance in the direction of the central axis, as in a modification of the fourth embodiment shown in FIG. 8, which will be described later). The fitting connection portion 11 can be connected and separated by rotating the fitting portion 11 .

In this case, the relative rotation angle for connecting the containers (lid body 1) to be connected (the rotation angle for screwing together the fly screw-shaped undercut portions 14a and 15a) is determined from the viewpoint of operability. Therefore, the angle is set to 180° or less, preferably 90° or less (about 60° in this embodiment).

This fitting connection part 11 can obtain sufficient fitting strength even if the fitting dimension of the vertical wall 14 and the standing wall 15 in the central axis direction is reduced, so that the container (lid 1) can be made smaller. In addition, even if tensile force, bending force, or twisting force is applied to the connected containers in the direction of their central axes, the containers are difficult to separate from each other, and the connection and separation operations of the containers are not complicated. It can be made into an easy-to-use connected container.
