Description

[Detailed description of the invention] "Industrial Application Field" The present invention relates to a container with a cap for containing cosmetic liquid, etc., for example.

``Prior art'' In the case of a container with a cap, in which the cap is fitted by pushing down from above the neck of the container body, and the cap is removed by pulling it up,
The fitted state of the cap can be obtained by providing a concave or convex line on the outer surface of the container mouth neck, and a convex or concave line that fits into the concave or convex line on the inner surface of the cap peripheral wall. That's what I do.

``Problems that the invention aims to solve'' Conventional caps that are attached to and detached from the mouth and neck of the container body by pushing down and pulling up have the disadvantage that the fit between the mouth and neck of the container tends to loosen. .

The main purpose of this proposal is to eliminate these drawbacks.

"Means for solving the problem" The mouth and neck part 4 is erected via the shoulder part 3 that descends in an inversely tapered shape from the upper end of the upper end of the torso, and
The container body 1 has an engaging protrusion 5 attached to the upper edge of the descending shoulder, and a peripheral wall 8 hanging from the peripheral edge of the top wall 7 is fitted to the outer surface of the mouth and neck, and the opposite lower end of the peripheral wall is fitted. It consists of a cap 6 in which the tip of an elastic plate 10 protruding obliquely upward and outward through a bending part 9 is brought into pressure contact with the engagement protrusion 5 against the elasticity of the elastic plate,
The elastic plate 10 is configured to be elastically reversible using the bent portion 9 as a fulcrum by attaching and detaching the cap to and from the mouth and neck.

"Function" When the cap 6 is attached and detached, an elastic plate 10 is attached to the lower end of the cap at a position opposite to the circumferential wall of the cap via a bent part 9.
As is clear from the comparison between FIG. 1 and FIG. 3, the cap is elastically inverted, and when the cap is fitted, the inner surface of the top wall of the cap comes into pressure contact with the upper end surface of the neck of the container body. The elastic plate emits sound when it inverts its elasticity.

"Embodiment" First, a first embodiment shown in FIGS. 1 to 3 will be described. Reference numeral 1 indicates a container body. The upper part of the body 2 of the container body is formed into a circular shape with a notched upper part when viewed from the front, and a rectangular shape which is elongated in the left-right direction when viewed from above. The shoulders 3, 3 are lowered in a reverse tapered shape from the upper ends of both left and right parts of the upper end of the torso, and the mouth and neck part 4 is raised from the middle of the shoulders. At the upper end edges of the shoulders 3, 3, engaging protrusions 5, 5 protrude obliquely upward and inward.

Reference numeral 6 denotes a cap, which has elastic plates 10, 10 protruding obliquely upward and outward from both left and right sides of the lower end of the peripheral wall 8, which is suspended from the peripheral edge of the top wall 7, through bent parts 9, 9, and curved downward against elasticity. The tips of the elastic plates are brought into pressure contact with the engaging protrusions 5, 5. As shown in the figure, the elastic plates 10, 10 are wider than the peripheral wall of the cap, and elastic plate portions 10a, 10a protruding from both ends of the bent portion are extended downward and inwardly, and bent portions 11, 11 are formed between the two elastic plate portions. They may also be connected via. In this way, the bending angle of the elastic plate when the cap is removed becomes accurate. When the cap is pulled upward from the container mouth neck 4 from the state shown in FIG. 1, the elastic plates 10, 10 are elastically inverted and assume a shape projecting obliquely downward and outward as shown in FIG.

In the case of the second embodiment shown in FIGS. 4 and 5, the inversely tapered shoulder 3 is suspended from the entire circumference of the upper end of the body 2, and the engaging protrusion 5 on the upper edge of the shoulder is also provided throughout the entire circumference. An elastic plate 10 is also provided to protrude from the entire circumference of the lower end of the cap peripheral wall. Further, in the second embodiment, the container body and the cap are circular when viewed from above, but in this embodiment as well, they may be square as in the first embodiment.

``Effect of the invention'' Since the present invention has the above-described configuration, the cap can be quickly attached and detached by simply pushing down and pulling up the cap against the mouth and neck of the container, and when attaching and detaching, the elastic plate
0 elastically inverts against the elasticity, so the cap will not be accidentally removed from the cap-attached state. When attaching the cap, do so against the elasticity of the elastic plate, and after passing the dead center Due to the restoring force of the elastic plate, the main body of the cap, excluding the elastic plate, automatically descends and fits into the mouth and neck, so there is no chance of incomplete fitting of the cap.
