Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a container having a cap that can be attached and detached with a single touch.

"Prior Art" Conventionally, many types of caps of this type have been provided. For example, the cap peripheral wall is double-layered inside and outside, the inner peripheral wall is engaged with the outer surface of the container mouth neck via an engaging protrusion, and push buttons that can be pushed are provided on both sides of the outer peripheral wall. The button is slid over the shoulder of the container, pushes up the internal peripheral wall, disengages it, and separates it from the mouth and neck.

"Problems that the invention attempts to solve" In the above conventional method, in addition to the engaging protrusion on the internal peripheral wall,
It requires a pair of pushbuttons on the outer circumferential wall and a mechanism for pushing up the inner circumferential wall with these pushbuttons, making the structure complicated.Also, since the pushbuttons are pushed in with the fingertips, force is required for operation. The pushbuttons on both sides are visually unsightly.

The object of the present invention is to obtain a container having a simple structure, a simple appearance, and a one-touch cap that is easy to operate.

"Means for Solving the Problems" The container of the present invention has an outer surface that is slightly tapered upward, and parallel flat surfaces 3, 3 on both sides of the base of the outer surface.
It consists of a container body 1 having a mouth and neck part 5 which is cut into a shape and has downward stepped parts 4, 4 formed just above the container body 1, and a rotatable cap 2 which is attached to the mouth and neck part 5,
The cap 2 is installed inside the cap body 6 by fitting and fixing the central part to the back surface of the top of the cap body 6, and bending the elastic deformable parts 7 of both wings downward and inward. The mouth and neck part 5 is pressed from both sides, and the engaging protrusions 8, 8 at the tips thereof are brought into contact with the flat surfaces 3, 3 to engage the downward step parts 4, 4, and the back surface of the central part It is characterized by comprising an elastic engagement plate 10 that closes the opening 9 of the neck 5.

"Operation" In the above, normally, as shown in FIG. The protrusions 8, 8 engage with the downward step portions 4, 4, thus maintaining the mounted state shown in the drawing.

To remove cap 2, grasp cap body 6,
The cap 2 may be rotated approximately 90 degrees via the cap body 6. Then, the elastic deformation parts 7, 7 expand and move to the arcuate surfaces 5a, 5a on the other side of the mouth and neck part 5. However, since these arcuate surfaces 5a, 5a do not have a stepped portion and are sloped surfaces that taper upward, the elastically deformable portions 7, 7 automatically slide upward by their own elasticity, and this movement It separates from the mouth and neck 5 and the cap 2 comes off.

At the time of installation, the cap 2 can be simply pushed downward in the position shown in FIG. That is, both removal and installation can be done with one touch.

``Example'' The container of the present invention has flat surfaces 3, 3 on both sides of the mouth and neck 5.
A container body 1 having downward step portions 4, 4 formed directly above the container body 1; a cap body 6; It consists of a cap 2 and an elastic engagement plate 10 that presses the neck 5 from both sides, and is molded and manufactured from a synthetic resin material.

The container body 1 has a rectangular shape and has a mouth and neck part 5 erected from a flat shoulder part 11. This mouth and neck part 5 is made by separating the upper half part 5B for convenience of molding process, cutting the lower outer surface of the upper half part 5B to make it thin, and fixing this thin part to the lower half part 5A by internally fitting it. It is integrally formed, and the outer surface extending from the lower half 5A to the upper half 5B is tapered in the shape of a hanging bell, and the opening 9 at the top has a small diameter and projects in the shape of a short cylinder. flat surfaces 3, 3 parallel to the bases on both sides are cut, and downward step portions 4, 4 are formed directly above the flat surfaces 3, 3.
is formed.

The cap body 6 of the cap 2 has a rectangular shape corresponding to the container body 1, which is an upward extension of the body of the container body 1, and has engaging protrusions 12, 12 on the upper inner surface on both longitudinal sides of the hanging peripheral wall. has been established.

The elastic engagement plate 10 has a long plate shape, and a central portion 13 having a shape corresponding to the top of the cap body 6 is pushed into and fixed to the back surface of the top of the cap body 6 using the engagement protrusions 12, 12. Elastic deformation parts 7, 7 that curve downward and inward to press the mouth and neck part 5 from both sides are formed on both sides of the central part 13 in the longitudinal direction, and engaging protrusions 8, 8 are formed on the inner surfaces of their tips. The engaging protrusions 8, 8 are brought into contact with the flat surfaces 3, 3, and are engaged with the downwardly directed step portions 4, 4. Reference numeral 14 denotes a ring stopper hanging down from the back surface of the central part 13, and is connected to the opening 9 at the top of the mouth and neck part 5.
The opening 9 is sealed.

"Effect of the invention" As described above, in the present invention, the outer surface of the mouth and neck part 5 of the container body 1 is inclined upwardly, and the flat surfaces 3, 3 are cut on both sides, and a downward step is formed directly above the flat surfaces 3, 3. 4, 4, while on the cap 2, normally located on said flat surface 3, 3, and therefore with a downwardly facing step 4, 4.
The cap 2 is provided with elastically deformable parts 7, 7 that engage with the cap 2 to maintain a stable wearing state, and when removed, the cap 2 is rotated approximately 90 degrees and the elastically deformable parts 7, 7 are attached to the inclined outer surface of the mouth and neck part 5. Since they are positioned at 5a and 5a, they can be removed and installed with one touch.
Further, since the cap 2 can be formed from a very simple-shaped cap body 6 and an elastic engagement plate 10, the structure is simplified, and since the external appearance is only the outer surface of the cap body 6, it is simple and easy to operate.
