Description

[Detailed description of the invention] The present invention relates to a container consisting of a screw-in type cap and a main body. The present invention relates to an air freshener container that can maintain a constant temperature.

Containers that can change the amount of aroma have been proposed in the past, but these closed structures consist of a closed stopper and a double movable stopper or cap, making manufacturing and assembly complicated and requiring many steps. It had the following characteristics. In addition, there have been other problems such as difficulty in refilling the fragrance for the user.

This invention was made in view of the above points,
The amount of fragrance can be changed in multiple stages, and the amount of fragrance can be maintained constant by preventing the cap from loosening or tightening due to vibrations, etc., and the structure is simple and easy to manufacture and assemble. To provide a fragrance container that can be easily refilled.

Examples of the fragrance container of the present invention will be described in detail below based on the drawings. Figures 1 to 4 are explanatory diagrams of the embodiment of the present invention, in which Figure 1 is a perspective view of the air freshener container of the present invention, Figure 2 is a perspective view with a portion of the cap in section, and Figure 3 is the main body. The perspective view, FIG. 4, is a sectional view taken along section line A-A' in FIG.

The fragrance container of the present invention consists of a cap 1 and a main body 2, as shown in FIG. 1, and the cap has an opening 5. FIG. 2 explains this cap. The cap 1 consists of an inner inner cylinder 3 and an outer outer cylinder 4. The outer outer cylinder 4 is provided with an opening 5, and the inner peripheral surface of the outer cylinder 4 is has a threaded portion 8 and a recessed portion 7. 3' indicates the bottom surface of the inner cylinder 3. The main body 2 to which the cap 1 is attached includes
As shown in FIG. 3, the main body neck 2' is provided with an opening 5', a threaded part 8', and a convex part 7'. The uneven portion 7 provided on the cap outer cylinder and the neck of the main body;
7' is a cap fixing device, and when the cap is loosened, the cap's outer cylinder and the opening 5,
When part or all of the caps 5' are aligned, the concave and convex portions 7, 7' are engaged to fix the cap, thereby preventing the cap from loosening or tightening due to vibrations or the like. Further, in this embodiment, even when the cap is tightened, the concave and convex portions are engaged and the cap is fixed.

Next, a container equipped with a cap will be explained. In Fig. 4, the cap 1 is screwed into the neck 2' of the main body 2 through threaded parts 8, 8' provided on the cap and the neck of the main body, and when the cap is tightened, the inner cylinder 3 of the cap is screwed. The bottom bottom surface 3' of the lower end and the annular protrusion 6 provided on the inner peripheral surface of the main body neck 2' are in close contact to keep the container airtight, and the outer peripheral surface of the neck 2' is Tube 4
The inner circumferential surface of the neck portion 2' is in contact with the outer circumferential surface of the cap inner cylinder 3. The cap 1 is loosened during use, and by loosening the cap, a gap is created between the bottom surface 3' of the lower end of the cap inner cylinder and the annular protrusion 6 on the inner peripheral surface of the neck of the main body. When the opening 5 of the outer cylinder and the opening 5' of the main body neck are partially, half, or completely engaged, the cap is fixed by engaging the uneven parts 7, 7', which are the fixing devices. . When some or all of the openings 5, 5' are aligned, the aromatic agent in the container evaporates from the core material a and passes through the gap between the bottom surface 3' of the lower end of the inner cylinder of the cap and the convex part 6 of the neck of the main body. , are emitted to the outside through the openings 5, 5'. 9 indicates the inner stopper, which is used to prevent the fragrance from spilling out, and there is a small hole 1 in a part.
0, so that the fragrance does not blow out due to temperature changes. The core material a is made of a material that permeates the fragrance. Also, a gap is required between the outer circumferential surface of the inner cylinder 3 and the inner circumferential surface of the neck portion 2';
It is preferable that the outer circumferential surface of the neck portion 2' and the inner circumferential surface of the outer cylinder 4 be configured to be in close contact with each other to prevent the cap from rattling. Refilling of the fragrance is done by removing the inner stopper 9 together with the core material a.

FIGS. 5 and 6 illustrate the cap 11 and main body 12 of other embodiments, with openings 15, 1
5' are provided above and below the threaded portions 18, 18', and the fixing device is constituted by annular concavo-convex portions 17, 17' provided on the inner circumferential surface of the cap outer cylinder and the outer circumferential surface of the container neck.

Of course, the shape, position, and number of the openings provided in the cap outer cylinder and main body neck are not limited to those described above, but an appropriate number of openings may be provided in appropriate shapes and at appropriate locations on the cap outer cylinder and main body neck. ,
Furthermore, the position and number of the fixing devices are not limited to those mentioned above, but an appropriate number may be provided at appropriate locations on the inner circumferential surface of the outer cylinder of the cap and the outer circumferential surface of the main body neck in contact therewith, and the unevenness of the fixing devices may A convex portion may be provided on the cap, and a concave portion may be provided on the neck of the main body, and the opening state may also be changed to two or four or more steps in addition to the three steps described above.

The air freshener container of the present invention configured as described above is
In addition to being able to change the amount of fragrance in multiple stages, the cap does not loosen or tighten due to vibrations, etc., so the amount of fragrance can be maintained at a fixed amount without fluctuation, and its structure is simple, making it easy to manufacture and assemble. It also has the advantage that the fragrance can be easily refilled.
