BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container.

[0002]

[Prior art]

SUMMARY OF THE INVENTION A container body with its mouth and neck rising from the upper end of the cylindrical body and a top wall that closes the mouth and neck upper opening from the upper edge of the peripheral wall fitted to the outer periphery of the mouth and neck. 2. Description of the Related Art A liquid storage container in which a cap provided is detachably mounted is known. For the purpose of expressing unused contents, for example, a shrink pack is made of a synthetic resin film by covering the periphery of the cap or covering the entire container including the cap portion.

[0003] However, shrink packs require a high raw material cost, require equipment for the shrink packs, and require some trouble to remove the film.

The present invention proposes a liquid container which can express the unused contents without special packaging and can be easily opened.

[0005]

In order to solve the above-mentioned problems, the container according to the present invention has a container body 2 having a mouth and neck 6 erected from a cylindrical body 4 and a cap 3 detachably attached to the container body 2.
The cap 3 has a top wall 8 extending from an upper edge of a peripheral wall 7 screwed to the outer periphery of the mouth and neck 6 to close the upper opening of the mouth and neck 6, and a flat plate at the center of the upper surface of the top wall 8. Inner wall material 3A having a protruding projection 9 and the inner wall material peripheral wall 7
From the upper edge of the peripheral wall 13 fitted to the outer periphery, a top wall 14 whose central lower surface is placed in contact with the upper surface of the protrusion 9 extends,
An outer wall material 3B is provided at a central portion of the top wall 14 and a cutout portion 17 with a handle 16 surrounded by a break portion 15 having a size that allows the protrusion 9 to protrude. And a concave / convex engaging means which engages the lower part of each of the peripheral walls 7 and 13 so that they cannot move vertically and can be forcedly released. ,
When the cutout portion 17 is broken off and the outer wall material 3B is forcibly pressed down against the inner wall material 3A, the concave / convex engaging means that engages with each other at the lowermost position of the outer wall material 3B is provided between the lower portions of the peripheral walls 7 and 13. They were provided mutually.

[0006]

In the state shown in FIG. 1, it can be seen at a glance that the content liquid is not used due to the presence of the cutout portion 17. Also, if the outer wall material 3B from which the cutout portion 17 has been cut and removed with the handle 16 is forcibly pushed down, the ridges projecting from the inner wall material peripheral wall 17 with the top wall 14 in contact with the upper surface of the inner wall material top wall 8 are provided. 11 Exterior wall material on the lower surface
The upper surface of the ridge 21 protruding from the lower portion 13 is locked, and the two are locked without play.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a liquid container. The container 1 includes a container body 2 and a cap 3, and the cap 3 further includes an inner wall material 3A and an outer wall material 3B.

The container body 2 has a mouth and neck 6 standing upright from a top end of a cylindrical body 4 via a shoulder 5.

The inner wall material 3A of the cap 3 is made of
A top wall 8 for closing the upper opening of the mouth and neck 6 is extended from an upper edge of the peripheral wall 7 screwed to the outer periphery, and a disc-shaped projection 9 is protruded at the center of the upper surface of the top wall 8. In addition, a seal tube portion 10 vertically provided from the rear surface edge of the top wall 8 is fitted in a liquid-tight manner at the upper end of the inner periphery of the mouth and neck portion 6. Further, a ridge 11 having an inclined surface whose upper surface is lowered outward is provided around the lower part of the outer periphery of the peripheral wall 7.
Above 11, a number of vertical ridges 12 are provided in the circumferential direction.

Further, the outer wall material 3B is connected to the inner wall material peripheral wall 7.
A top wall 14 is mounted on the upper surface of the protrusion 9 from the upper edge of the peripheral wall 13 fitted to the outer periphery, and a handle 16 surrounded by a broken portion 15 is provided at the center of the top wall 14. Is formed. The broken portion 15 is formed by integrally connecting circular cut grooves 15a having the same or slightly larger size as the plan view of the projection 9 of the inner wall material 3A with a plurality of thin rod-shaped broken pieces 15b. The handle 16 is in the form of a plate standing upright from the center of the upper surface of the top wall surrounded by the cut groove 15a. When the cutout portion 17 is broken and removed, a circular through hole 18 is formed at the center of the top wall 14, and the inner wall material projection 9 projects into the through hole 18.

A large number of vertical ridges 19 are provided on the inner peripheral upper portion of the peripheral wall 13 so as to be vertically movable and non-rotatably engaged with the vertical ridges 12 of the inner wall material peripheral wall 7. I have. Further, a concave groove 20 is provided at a predetermined lower position spaced apart from each of the vertical ridges 19, and the concave groove 20 is fitted to the outer peripheral edge of the ridge 11 of the inner wall material 3A so that the top wall 14 is formed. The peripheral walls 7 and 13 are configured so as not to be displaced in the vertical direction in a state where the lower surface is in contact with the upper surface of the inner wall material projection 9. The engagement between the ridge 11 and the concave groove 20 is configured to be disengaged when the outer wall 3B is forcibly pressed down against the inner wall 3A because the upper surface of the ridge 11 is inclined as described above. Further, a ridge 21 is provided at a predetermined position above the concave groove 20, and the outer wall material 3B from which the cutout portion 17 has been removed is forcibly pushed down against the inner wall material 3A. It is configured to engage with the lower surface of the ridge 11 of 3A and lock the two without play.

The above members are all formed of a synthetic resin.

[0014]

[Effects of the Invention] As described above, the container of the present invention has the above-described structure, so that it is possible to express the unused of the content liquid without special packaging such as a shrink pack and the structure is relatively simple. There is an advantage that it can be easily manufactured.

Further, after the cut-off portion is broken and removed by holding the handle, the outer wall material can be opened by a simple operation of forcibly pressing down the inner wall material, and the broken portion provided on the outer wall material top wall can be removed by the inner wall material. The projecting portion that projects from the top wall is configured to be of a size that can project, and the outer wall material is configured to slide down with respect to the inner wall material. Easy to do.

Further, since the cutout is opened to expose the flat protrusion of the central inner wall material, a plurality of flat shapes of the flat protrusion are prepared, and the inner wall material and the outer wall material are prepared. If a plurality of colors are prepared, an extremely large number of types of containers can be formed by combining them.
