[Industrial applications]

 The present invention relates to a double-barreled container in which a container body is composed of a lid body and a container body, which are connected to each other at a bottom portion thereof, and an inner body, and the outer body is transparent. The present invention relates to a double-barreled container in which an outer body and an inner body are connected by a connecting mechanism that has both a function and a rotation-stopping function, is hard to see from the outside, and can be applied to a non-circular container.

[0002]

[Prior Art]

 A double-body container in which the container body is composed of an outer body and an inner body that are concentrically arranged and connected to each other, and the inner body contains a cosmetic such as cream and other contents and is provided with a lid. Is widely known as disclosed in Japanese Utility Model Publication No. 46-32150 and Japanese Utility Model Publication No. 52-39599.

Such a double-body container gives the outer body a larger appearance than the real body and increases stability when placed on a table or the like. Further, the lid body, the outer body, and the inner body have different colors from each other. It is suitable as a container for cosmetics because it can give a good design effect by using different materials or different kinds of materials, and most of them are suitable for the outer body disclosed in Japanese Utility Model Publication No. 46-32150. The inner shell and the bottom are screwed together.

[0004] Thus, when the outer body is made of a transparent material, the one having the screw connection at the bottom has an advantage that the connection mechanism is hard to see under a normal state placed on a table or the like and the appearance is not damaged. However, there is a limitation that it can only be applied to a circular container, and in the case of a structure in which the lid body is screwed to the inner body, there is a concern that the lid body and the inner body will rotate together with the outer body. There is.

On the other hand, as disclosed in Japanese Utility Model Publication No. 52-39599, the upper edge of the outer case and the middle abdomen of the inner case are connected to each other and rotated by a rotation preventing mechanism at the bottom. With this configuration, there is no concern about co-rotating the lid and the inner body, but on the other hand, the coupling mechanism and the anti-rotation mechanism are provided separately, so the configuration is complicated and the outer body is transparent. When made of certain materials, the coupling mechanism is easily visible and significantly impairs the appearance.

[0006]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to make the outer body made of a transparent material so that the lid and the inner body rotate together so that they are not easily visible so as not to damage the appearance. The point is that there was no worry, and there was no double-barreled container in which the outer and inner bodies were connected by a connecting mechanism that was applicable to non-circular containers.

[0007]

[Means for Solving the Problems]

 According to the present invention, when the outer case is made of a transparent material, a protrusion is formed on the upper surface of the bottom wall to provide an engaging hole extending in the longitudinal direction, and a recess is formed on the lower surface of the bottom wall of the inner case. The outer and inner shells are provided by providing an engaging projection of approximately the same length as the engaging hole on the outer peripheral surface, making the outer surface of the recess circumscribe the ridge, and engaging the engaging projection into the engaging hole. The outer and inner shells are joined by a connecting mechanism that has both a binding function and a rotation stopping function, is difficult to see from the outside, and can be applied to non-circular containers. The purpose of obtaining a double barrel container is achieved.

[0008]

[Action]

 When the inner shell is inserted concentrically from above into the outer shell, the peripheral surface of the recess overlaps with the ridge, and at that time, the ridge is pushed by the engaging projection to be curved and deformed inward, and then the engaging ridge. When the joint protrusion fits into the engagement hole, the protrusion is restored and comes into contact with the peripheral surface of the recess. Since the engagement holes and the engagement protrusions have almost the same length, the outer case and the inner case can be connected to each other without rotating, and since they are not screw-type, they can also be applied to non-circular containers, and the connection mechanism is It is hard to see because it is located at the bottom and inside the hollow of the inner case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. 1 is a lid body, 11 is an outer body, 21 is an inner body, and the lid body 1 is a circular upper peripheral wall 23 of the inner body 21. A skirt wall 3 having an inner peripheral surface with a female thread 2 threadedly engaged with a male thread 24 provided on the outer peripheral surface, and an upper wall 23 of the upper peripheral wall 23 covering the upper surface of a cavity 22 opened above the inner case 21. A top wall 5 holding a packing 4 overlaid on the top edge. The outer case 11 is made of a transparent material, that is, a transparent or translucent material, and is formed in a non-circular shape having a substantially square shape in a plane, and a convex ridge 14 having a substantially square shape in a plane shape is projectingly formed on the upper surface of the bottom wall 13. .. The outer side surface 15 of the ridge 14 is a vertical surface parallel to the central axis of the outer case 11, and the upper end edge of the ridge 14 is formed as an inclined surface 16 that is inclined inward, and the ridge 14 faces the ridge 14. Engagement holes 17 of substantially the entire length are formed penetrating both inside and outside sides on the two sides, and a positioning projection 18 protruding outward is formed on one side between them. It is formed to project.

The lower peripheral wall 25 of the inner case 21 is formed in a shape having an outer peripheral surface that is similar in shape to the peripheral wall 12 of the outer case 11 and is substantially square in plan view, but the inner cavity 22 is entirely circular, An annular projecting edge 26 that projects outward is provided between the upper peripheral wall 23 and the lower peripheral wall 25. Further, a bottom surface 27 of the inner case 21 is provided with an indentation 28 having a substantially square plane, and its peripheral surface 29 is a vertical plane parallel to the central axis of the inner case 21 and outside the ridge 14. It is formed so as to circumscribe the side surface 15. Engaging projections 30 of approximately the same length as the engaging holes 17 are formed to project inwardly at the lower end edges of the two opposite surfaces of the recess 28, and one surface between them is used for positioning. A recess 31 is formed.

FIGS. 1 and 2 show a state in which the outer case 11 and the inner case 21 are connected to each other to form a double case container, and the protrusion 18 is fitted into the recess 31 to form the outer case 11 and the inner case 21. The circumferential surface 29 of the recess 28 circumscribes the outer surface 15 of the ridge 14, and the engaging projection 30 engages with the engaging hole 17 in the circumferential direction. The upper edge of the peripheral wall 12 of 11 is in contact with the lower surface of the projecting edge 26.

3 and 4 show a situation in which the outer case 11 and the inner case 21 are connected to each other. The inner case 21 is concentrically inserted into the outer case 11 and the peripheral surface 29 of the recess 28 projects. When it comes to overlap with the outer side surface 15 of the strip 14, the engaging projection 30 collides with the inclined surface 16 to bend and deform the projecting strip 14 inwardly, and then the engaging projection 30 of the engaging hole 17 is formed. When it is inserted until it is located to the outside, the ridge 14 is restored by its own elastic force, the outer surface 15 contacts the peripheral surface 29, and the engaging projection 30 is fitted and engaged in the engaging hole 17. is there.

When the outer case 11 and the inner case 21 are coupled in this way, the engaging projections 30 do not come off from the engaging holes 17 even if they are pulled in opposite directions in the central axis direction, so that they are separated. There is no. Further, even if they are rotated in the opposite directions, the engagement projection 30 and the engagement hole 17 have substantially the same length, and in the embodiment, both the peripheral wall 12 and the lower peripheral wall 25 are non-circular and concentric with a narrow gap. Since it is arranged in a fixed manner, it does not rotate, and even if it is rotated to remove the lid body 1, the inner case 21 does not rotate together.

When the protrusion 14 and the recess 28 are formed in a non-circular shape as in this embodiment, even if the protrusion is a circular container, they act as detents, but the protrusion 14 and the recess 28 are circular. Even if formed, the engaging hole 17 and the engaging protrusion 30 have substantially the same length, and thus they effectively function as a rotation stop. Further, since such a coupling mechanism is arranged inside the recess 28 formed in the lower surface of the bottom wall 27 of the inner case 21 which is generally made of a material having no transparency, it is placed in a normal state on a table or the like. Is the most difficult to see. Further, two sets of the engagement holes 17 and the engagement protrusions 30 are provided in the illustrated embodiment, and by arranging the plurality of sets symmetrically with respect to each other in this manner, it is possible to firmly and firmly couple them. However, it does not matter even if it is one group.

[0015]

[Effect of the device]

 According to the present invention, a recess is formed on the bottom surface of the bottom wall of the inner case to provide an engaging projection, and the circumferential surface of the recess is circumscribed to the projection formed on the top surface of the bottom wall of the outer case to form an engaging hole of the projection. Since the engaging projections of approximately the same length as this are inserted and engaged, it is difficult to see the coupling mechanism through the transparent outer case, and thus the appearance is significantly impaired and the design effect is reduced. There is nothing to say. In addition, the coupling mechanism also has a function as a detent, so that it can be applied to a circular container with a simple structure, and it can also be applied to a non-circular container because it is not screwed.
