Abstract

PROBLEM TO BE SOLVED: To provide an aerosol container in which injection sound generated when content liquid is applied to the skin of a user can easily be reduced to such a degree as one not hindering the ears of the user. SOLUTION: This aerosol container 10 has a nozzle section 11 provided with a sound muffling means. The sound muffling means is comprised of an annular wall 15 arranged along a circumferential edge part of the upper surface of a nozzle section 12 to enclose a plurality of injection ports 13. When the nozzle section 12 is depressed with a foot, the inner side of the annular wall 15 is sealingly closed to cause injection sound generated through the injection ports 13 to be hardly leaked out of the container and then a sound muffling effect is realized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an aerosol container.

[0002]

2. Description of the Related Art In a conventional aerosol container, the sound of jetting when applying a content liquid is annoying.

[0003] It is an object of the present invention to provide an aerosol container which can easily reduce the spray noise when applying a content liquid to a level that does not cause harshness.

[0004]

The aerosol container of the present invention is provided with a muffler at a nozzle portion thereof.

In addition, the aerosol container is provided with stability so that it does not fall down even if it is stepped on with a foot, and the upper end of the annular wall is provided with an opening large enough to be covered with the back surface of the foot. It can be used as a foot-type application container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an aerosol container 10, which is a preferred embodiment of the present invention, comprises a container body 11 for containing a liquid content such as a cooling agent, a bactericide, and a fragrance. A nozzle portion 12 protruding above the container body 11, and by pressing the nozzle portion 12, the nozzle portion 12
The liquid in the container body 11 is jetted from the surface of the container.

This aerosol container 10 is used, for example, to be installed under a desk at a workplace, to press down on the nozzle portion 12 with a foot and press it, to spray a liquid content, and apply it to the back of the foot.

The container body 10 is a hollow container having a circular cross section made of synthetic resin, metal, or the like.
The height and height of the nozzle unit 1 of the aerosol container 10 are about 8 cm, and have a low center of gravity.
2 is placed on the floor in a stable state such that it does not fall even if it is pressed with a foot.

The diameter of the nozzle section 12 is approximately 5 mm.
cm and a disk shape with a height of about 1.5 cm. On the upper surface of the nozzle portion 12, as shown in FIG.
Location, 6 locations along the circumferential direction, a total of 7 locations
A 3 mm ejection port 13 is opened, and a projection 14 having a height of about 5 mm is located between the ejection ports 13 in the circumferential direction.
Are provided at six locations. Since the seven outlets 13 are substantially uniformly dispersed on the upper surface of the nozzle portion 12, the inner solution can be sprayed over the entire upper surface of the nozzle portion 12. The six projections 14 dig into the acupoints on the back of the foot when the nozzle portion 12 is pressed down by stepping on the foot, thereby stimulating the acupuncture points, and exerting the acupressure effect. Secure.

An annular wall 15 having a height of about 5 mm is formed at the periphery of the upper surface of the nozzle portion 12 so as to protrude so as to surround seven injection ports 13. The annular wall 15 is a double-walled body composed of an outer circumferential wall 16 and an inner corrugated wall 17, and an outer convex portion 18 of the inner corrugated wall 17.
Are joined to the inner surface of the outer circumferential wall 16, and a gap 20 having a substantially triangular cross section is formed between the outer recess 19 of the inner corrugated wall 17 and the inner surface of the outer circumferential wall 16 for each wave crest. Is formed.

The nozzle portion 12 of the aerosol container 10 placed under the desk is pressed and pressed by the foot while covering the annular wall 15 from above with the portion of the underside of the foot where the content liquid is desired to be applied. The liquid is jetted from the jet port 13 and applied to the back of the foot. Here, the annular wall 15 is arranged with a diameter of about 4 cm along the periphery of the upper surface of the nozzle portion 12 and its installation area is large enough to be sufficiently covered by the back surface of the foot. The inside of the wall 15 is sealed, so that the injection noise from the injection port 13 is hardly leaked, and a noise reduction effect is exhibited. Further, the spray distance from the ejection port 13 is ensured by the height of the annular wall 15.

The sound pressure level of the aerosol container 10 of the present embodiment in which the annular wall 15 is disposed as a sound deadening wall and the sound pressure level of the aerosol container from which the sound deadening wall is removed when spraying is compared and measured with the same propellant pressure. In the case of an aerosol container without a sound deadening wall, it is 68 dB (sound inside a train), whereas the aerosol container 10 with a sound deadening wall is 57 dB.
(The sound of ordinary conversation at a distance of 1 m), and a clear noise reduction effect was recognized. In addition, this measurement was performed in the environment of the surrounding sound of 50 db at a distance of 0.1 m from the nozzle using a sound level meter NA-09 (manufactured by Rion Co., Ltd.).

According to this embodiment, the annular wall 15 has a double structure consisting of the outer circumferential wall 16 and the inner corrugated wall 17, and the gap 20 is formed between them, so that the sound deadening effect is obtained. Is enhanced. Further, if the annular wall 15 is formed using a foamed resin molding material, the effect of silencing the injection noise can be further increased. A foaming material such as foamed polyethylene may be attached to the inner surface of the inner corrugated wall 17 to increase the sound deadening effect. Further, the sound deadening effect can be enhanced by forming the inner surface of the annular wall 15 into, for example, a tooth shape.

The present invention can be variously modified without being limited to the above embodiment. For example, the aerosol container of the present invention can be used as an aerosol container for applying the internal solution not only to the soles of the feet but also to other affected parts or parts other than the human body. In addition, the annular wall disposed along the upper surface peripheral portion of the nozzle portion does not necessarily have to have a double structure including the outer circumferential wall and the inner corrugated wall. An annular wall may be provided alone or double along the periphery of the upper surface. Further, the outer peripheral wall and the inner corrugated wall are partially separated from each other without being joined, and an annular wall or a substantially triangular cross section between the outer peripheral wall and the inner corrugated wall is filled in to form a gap therebetween. An integral annular wall can also be employed. In addition, an aerosol container of the present invention may be provided by providing a muffling means other than the annular wall provided around the jet port. Also, a roof member having a cutout along the shape of the foot, for example, may be joined to the upper end of the annular wall to form an opening large enough to cover the cutout with the back surface of the foot.

According to the aerosol container of the present invention, the spray noise when applying the content liquid can be easily reduced to a level that does not cause harshness.
