Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a container with a cap.

``Prior Art'' In this type of container, the cap has conventionally been attached to the container body in most cases by threading or uneven engagement.

``Problems that the invention aims to solve'' In conventional containers, where the cap is screwed onto the container body, the cap must be rotated many times with respect to the container body when attaching and detaching, which takes time. Moreover, in the case where the cap is engaged with the uneven stripes, a large force must be applied to both the cap and the container body when the cap is pulled up and removed, which is troublesome.

The present invention was devised in consideration of these circumstances, and an object of the present invention is to provide a container with a cap that can be quickly and easily attached and detached.

"Means for Solving the Problems" In order to achieve the above object, the present invention provides a container in which a neck part 3 is erected from the upper end of a body part 2, and an engaging protrusion 4 is provided around the lower part of the outer surface of the neck part. It consists of a body 1 and a highly elastic synthetic resin cap 5 fitted onto the outer surface of the mouth and neck.

The cap has a peripheral wall 7 hanging from the periphery of the top wall 6, and a pair of arc-shaped walls 8, 8 extending from symmetrical positions on the lower surface of the top wall, the inner lower part of which fits into the outer surface of the engaging protrusion, respectively. The engaging protrusions 9 that engage with the lower surfaces of the engaging protrusions are attached to the lower inner surfaces of the arcuate walls, and are formed on the inner surfaces of the circumferential wall between both side ends of each of the arcuate walls. Wedge-shaped protrusions 10, 10 are located at positions facing into the small gap.
are installed vertically, and by pressing and deforming the outer surface of the peripheral wall of the vertically installed portions inward, the wedge-shaped protrusions 10,
10 is fitted into the small gap to form the lower part of the arc-shaped wall so that it can be expanded and deformed outward.

"Operation" When the outer surface of the peripheral wall 7 of the portion where the wedge-shaped protrusions 10, 10 are vertically installed is pressed inward and deformed, the wedge-shaped protrusions 10, 10 fit into the small gap and form an arc shape as described above. The lower portions of the walls 8 and 8 are expanded and deformed outward.

As a result, the engagement protrusion 9 is disengaged from the engagement protrusion 4, and the cap 5 can be removed from the outer surface of the mouth and neck portion 3.

When attaching the cap 5, use the above-mentioned engagement protrusion 9.
It is obvious that it is sufficient to fit the lower inner surfaces of the arcuate walls 8, 8 onto the outer surface of the engagement protrusion 4 until they are elastically engaged with the lower surface of the engagement protrusion 4.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figures 1 to 3 show an embodiment of the container with a cap of the present invention, which has a neck part 3 erected from the upper end of a body part 2 and an engaging protrusion 4 on the lower part of the outer surface of the neck part. It consists of a container body 1 disposed around the periphery, and a highly elastic synthetic resin cap 5 fitted onto the outer surface of the mouth and neck.

The cap 5 has a peripheral wall 7 suspended from the periphery of the top wall 6, and a pair of arcuate walls 8, 8 suspended from symmetrical positions on the lower surface of the top wall, the inner lower portions of which fit into the outer surfaces of the engagement ridges, respectively. and an engaging protrusion 9 that engages with the lower surface of the engaging protrusion is attached to the lower inner surface of the arcuate wall, and an engaging protrusion 9 that engages with the lower surface of the engaging protrusion is formed on the inner surface of the peripheral wall between both end portions of each of the arcuate walls. The wedge-shaped protrusions 10, 10 are vertically installed at positions facing into the small gap, and the outer surfaces of the circumferential walls of the vertically installed portions are pressed and deformed inward, so that the wedge-shaped protrusions 10, 10 fit into the small gap. Together, the lower part of the arcuate wall is formed to be deformable and expand outward.

The stem 11 is erected from inside the container mouth neck 3,
A fluid ejecting head 12 is fitted onto the upper end of the stem. Therefore, in this embodiment, the present invention is applied to an aerosol type sprayer.

The mouth and neck part 3 stands up from the upper end of the body part 2 via a tapered shoulder part 13, and the cap peripheral wall 7
The lower end surface of the cap is placed on the lower part of the upper surface of the shoulder portion when the cap is attached. Therefore, when the cap is detached, the engagement between the engagement protrusion 9 and the engagement protrusion 4 is released by the wedge-shaped protrusions 10 and 10 entering the above-mentioned small gap, and at the same time, the lower end surface of the peripheral wall 7 and the engagement protrusion 4 are released. The cap 5 is pushed upward by sliding contact with the tapered shoulder portion 13. In this way, since the engaging protrusions 9 automatically get over the engaging protrusions 4, the cap can be easily removed even if the inward pressing of the outer surface of the rear peripheral wall 7 is stopped.

The engaging protrusions 9 are attached to the lower portions of both inner surfaces of the arcuate walls 8, 8, respectively.

"Effects of the Invention" As explained above, according to the present invention, the engaging protrusions on the peripheral wall of the cap and the engaging protrusions on the neck of the container are elastically engaged, and the engaged state is easily maintained by a wedge action. Since the cap is configured so that it can be released by a simple pressing operation, the effect that the cap can be quickly and easily attached and detached is obtained.

Claims (1)

[Scope of utility model registration request] A container body 1 in which a neck part 3 stands up from the upper end of a body part 2 and an engaging protrusion 4 is provided around the lower part of the outer surface of the neck part, and a synthetic resin cap 5 with high elasticity fitted onto the outer surface of the neck part. The cap consists of
A peripheral wall 7 is suspended from the periphery of the top wall 6, and a pair of arcuate walls 8, 8 whose inner lower portions fit into the outer surfaces of the engagement protrusions, respectively, are suspended from symmetrical positions on the lower surface of the top wall. Engagement protrusions 9 that engage with the lower surfaces of the engagement protrusions are attached to the lower inner surfaces of the arcuate walls, and small gaps formed between the opposite ends of the respective arcuate walls on the inner surfaces of the peripheral walls are provided.
