Abstract

PURPOSE:To securely hold a cap to a container after engagement therebetween and effect an easy uncapping by providing a ring-shaped cover body having a rail groove, a projection and an upper release opening adjacent to one side of the projection and a cap body having locking projections at the inner lower part thereof. CONSTITUTION:When a cap 4 is placed over a ring-shaped cover 2, locking projections 8 engage with a rail groove 3 of the ring-shaped cover 2. The cap 4 is then turned until it contacts in the direction opposite to the side of an upper release opening 7 adjacent to the one side of a stopper projection 6 forming a discontinuous part on the rail groove 3 and secured in place to eliminate the possibility of the cap 4 being inadvertently disengaged from ring-like cover 2. To remove the cap, the cap 4 is reversely turned until the locking projection 8 contacts the side of the upper release opening 7 adjacent to the one side of the stopper projection 6 and, when the cap 4 is pulled up, since the locking projections 8 are passed through the upper release opening 7 along the stopper projection 6, the cap 4 can be easily removed from the ring-shaped cover 2.

Description

[Detailed Description of the Invention] [Field of Application] The present invention relates to a lid device for an aerosol container, and its features include a ring-shaped cover body that fits a reed portion used in an aerosol product into a container body, and a cap. When the cap body is attached, the retaining protrusion of the cap body engages with the rail groove provided on the ring-shaped cover body, preventing the cap from being accidentally removed, and when the cap body is removed, it is fixed in a certain direction. After rotating the cap body, the retaining protrusion of the cap body passes through the opening of the ring-shaped cover body, allowing the cap body to be easily removed.

[Conventional technology and its problems]

Regarding the lid of an aerosol container, since the aerosol container itself has a valve mechanism with good airtightness to maintain its airtightness, it is fundamentally different from the lid of a bottle container, which prevents leakage of contents by tightening the lid. Their roles are different: the lid of a bottle container is the stopper itself, while the lid of an aerosol container is only a protective material for the button attached to the valve of the aerosol container. Most of the lids were of the type that were simply pushed onto a ring-shaped cover fitted to the top of the container. - At the time, there were special protective lids for aerosol products to protect them from childish mischief, but most of these require a special tool such as a screwdriver to remove the lid. The lid had to be pried open.

Recently, aerosol products have become more and more compact and are often carried around when traveling.However, when carrying the product, the lid of the aerosol product may come off in the bag and the button may hit an object inside the bag and be pressed, causing the contents to be lost. It often happens that people get wet and get dirty inside the bag.

For this reason, attempts have been made to make a lid of an aerosol container that tightly engages with the top of the aerosol container or with a ring-shaped cover fitted to the top of the aerosol container, and to make the fitting part hard, but all of these methods have not been successful. When removing the lid, it is difficult to remove due to the tight fit, which makes it unsuitable for products aimed at women.
Even if the lid is used by a man, it takes a lot of force to remove the lid, and one hand may slip, and the lid does not come off in the correct direction, but in a distorted direction, so the lid is placed on top of the aerosol container. This often results in the button getting caught and the button being torn off, rendering the product unusable.

[Problem that the invention seeks to solve]

Therefore, the inventor developed a structure that allows the lid and aerosol container part to fit together easily by simply pushing the lid on from above like a normal product, and to easily remove the lid when removing the lid. Various studies have been conducted in an attempt to provide a lid device for an aerosol container that has a structure that does not have the above-mentioned drawbacks, such that the lid and the aerosol container part are firmly fitted together after they are fitted together, and the present invention has been made here. It has been completed.

[Means for solving problems]

That is, the present invention has a ring-shaped discontinuous rail groove [3] that fits into the r(1) A container body and has an equal length on the circumference of the lower outer wall, and a protrusion that forms the discontinuous part. ■ and a ring-shaped cover body ■ with an upper opening [7] that momentarily contacts one side of the protrusion ■, B A retaining protrusion [8] at the lower end of the inside
(2) a container body [1
] The aerosol container according to claim 1, in which a button [phase] for injecting contents is connected with a part of the ring-shaped cover body [2] to be used by being attached to the core [3]. ``Lid device,''.

The configuration of this invention will be explained with reference to FIG. 1st
The figure is a perspective view showing a lid device for an aerosol container according to the present invention.

As shown in Fig. 1, the lid used for aerosol products is divided into a ring-shaped cover body [1] and a cap body ■ that fit into the container body [1], and the lower outer wall of the ring-shaped cover body [2] A discontinuous rail groove of equal length is provided on the circumference, a protrusion forming the discontinuous part, and an upper open opening [7] adjacent to one side of the protrusion are provided, and the cap body is provided with an opening at the lower end inside. This is an aerosol container lid device characterized by being provided with a stop protrusion [8].

[Action and effect]

The aerosol container lid device shown in FIG. 1 operates with the following characteristics.

First, a method for attaching the cap body (2) to the ring-shaped cover body (2) will be explained.

Usually, the lid of an aerosol container is made of an elastic material, so if the same material is used for the aerosol container lid device according to the present invention, when the cap body (■) is attached to the ring-shaped cover body (■), , place the cap body ■ on the ring-shaped cover body [2], and just by pushing it lightly and tapping it, the retaining protrusion ■ of the cap body ■ enters the rail groove ■ of the ring-shaped cover body [2], making it easy to install. It can be fitted. Of course, cut the bottom of the retaining protrusion ■ of the cap body ■ slightly diagonally upward inward, or cut it at the circumferential angle of the shoulder part ■ that corresponds to the top of the rail groove ■ of the ring-shaped cover body [2]. The cap body can be made more smoothly by rounding it or cutting it diagonally.
Needless to say, it becomes possible to attach the ring-shaped cover body■.

Next, a description will be given of what happens after the cap body (2) is attached to the ring-shaped cover body (2).

When attaching the cap body ■ to the ring-shaped cover body ■ fitted to the container body [1], the retaining protrusion ■ provided at the lower end of the cap body ■ and the rail groove ■ of the ring-shaped cover body [2] After installation, it is placed in a position where it will fit perfectly. However, the cap body ■ is replaced by a ring-shaped cover body ■
When attached to the ring-shaped cover body [2], the retaining protrusion ■
] When the retaining projection ■ that engages with the rail groove ■ is inside the rail groove ■ (not including the upper opening ■), it is impossible to move it up or down, but it can be moved along the rail groove ■. Since it is movable, the cap body (■) can be moved left and right with respect to the ring-shaped cover body (■). Then, grab the cap body ■ and rotate it to the right or left until it locks in the direction opposite to the side with the upper opening ■ adjacent to one side of the protrusion ■ that forms the discontinuous part of the rail groove ■. If you keep ■ in place, there is no possibility that the cap body ■ will accidentally come off from the ring-shaped cover body ■. Next, if you want to remove the cap body ■, conversely, the upper part adjacent to one side of the protrusion ■ Turn the cap body ■ to the side with the opening ■ until it touches the retaining protrusion ■.

When you pull up the cap body ■, the retaining protrusion ■ becomes a protrusion.
The cap body ■ can be easily removed from the ring-shaped cover body ■ because it passes through the upper opening [7] along the line.

As is clear from the above description, the implementation of the present invention prevents the cap from accidentally coming off while the aerosol product is being carried or stored, and the contents can be discharged and leaked by simply pulling it out. Since the cap is not removable, it is possible to prevent children from opening the cap at random and tampering with the contents. In addition, the structure is simple and can be implemented at low cost, making it extremely practical.

The protrusion that forms a discontinuous part by attaching the cap body■ to the
It is a perspective view when it is rotated until it touches the side opposite to the side with the upper open opening (■) adjacent to one side of and is fixed at the position where it is most difficult to come off. In Fig. 5, the content injection button [stock] is connected with a part of the ring-shaped cover body [2].

It is a perspective view showing the embodiment of the second claim showing an example of an integrated case, and when the content is injected, the content injection button [
Since the parts [phase] are only connected by a thin plate-shaped connecting part [phase], when the contents are injected, the contents can be taken out by simply pressing the content injection button [phase] as usual. FIG. 6 is a perspective view showing an embodiment in which the content injection button d is of a nozzle type, and in this case as well, it may be used in the same manner as the embodiment shown in FIG. 5. A resistance protrusion (■) is provided at the upper opening (■) of the ring-shaped cover body [2], so that if the cap body (■) turns inadvertently during loading or storage, the retaining protrusion (■) prevents the upper opening (■) from turning. This is a similar perspective view showing a case in which a resistance protrusion ■ is provided to maintain the same resistance to falling off as a conventional aerosol container lid so that the cap body ■ will not fall off by itself even if the cap body ■ moves to the desired position. It does not go beyond the scope of the present invention to provide a stationary resistive protrusion O to keep the retaining protrusion ■ of the cap body ■ in place at a position where it is most difficult to come off, adjacent to one side of the protrusion ■, as shown in O, if necessary. There's nothing to do.
