Abstract

<P>PROBLEM TO BE SOLVED: To provide the operation mechanism of an aerosol type container having a rubbing effect and a massage effect to a part to be jetted. <P>SOLUTION: Inside an operation member 4, an annular path 6d having a jetting port 5a, a ball 7 provided so as to be circulated inside the annular path 6d, and a spiral path 6c for making contents from a stem 3 flow in the direction of forming a turning flow in the annular path 6d are provided. When a user holds a container body 1 and presses the projection part 5b of the operation member 4 to the skin 9, since the turning flow of the annular path 6d generated by flowing power of the contents in the middle circulates the ball 7 in the path while discharging the contents from the jetting port 5a, centrifugal force by that gives high rubbing effect and massage effect to the skin 9 via the projection part 5b as vibrations. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to an operation mechanism that is attached to a stem for contents injection operation of an aerosol container and generates vibration during injection.

Depending on the application of the aerosol-type product, the contents are sprayed onto the sprayed part such as the skin, scalp and polishing surface (for example, the body of the vehicle body), and at the same time, physical effects such as vibration and friction are applied to the sprayed part. In some cases, it is desirable to make the contents adhering to the jetting part uniform, to allow the contents to penetrate into the jetted part, and to increase the activity of the jetted part (for example, the blood circulation of the skin or the surface activity of the material).
The present invention meets such a need.

  The contents to be applied include, for example, liquid or cream soap, cleaning agents, cosmetics, milky lotion, foaming shaving foam, hair styling foam, and the like as described later.

  A release mechanism having a function of giving a physical action to an injection target part to an operation part of an aerosol container is disclosed in, for example, Patent Document 1 below.

  In the release mechanism of Patent Document 1, a spherical arc piece 11 is provided in an operation unit for releasing a medicine (contents) of the container body 1.

  And by grasping the container main body 1 and sliding while pressing the ball arc piece 11 of the operation part against the scalp 19 (injected part), the pushed-in operation part opens the valve mechanism 5 via the nozzle 6. The scalp 19 can be simultaneously rubbed and massaged while spraying the medicine from the spray port 15.

  Further, after a sufficient amount of medicine has been ejected, the valve mechanism 5 is closed by loosening the pressing of the container body, and the medicine ejection is stopped. Even after stopping the medicine injection, the user can continue to give the scalp 19 a rubbing action / massage action by sliding the spherical arc piece 11 without changing the container body 1.

Japanese Patent Application Laid-Open No. 09-038536

  As described above, the rubbing action / massage action in the operation portion of the conventional aerosol container requires both the pressing operation and the sliding operation of the user.

  Therefore, in the present invention, the operation unit (injection unit) itself is vibrated by using the swirl flow of the content in the operation unit accompanying the pressing operation, so that the content is rubbed against the injection target by only a pressing operation. The purpose of the massage is to improve the convenience and efficiency of the contents injection mechanism.

It is assumed that a plurality of projecting portions (for example, a projecting portion 5b, a projecting portion 5c, and a projecting portion 5d, which will be described later) that come into contact with the ejected portion are provided.

  The present invention is directed to a vibration injection mechanism having the above-described configuration and an aerosol type product including the vibration injection mechanism.

  The vibration injection mechanism of the present invention vibrates the operation unit (injection unit) itself by using the swirling flow of the contents in the operation unit accompanying the pressing operation, so that only a simple pressing operation by the user is required. The contents are rubbed and massaged against the portion to be ejected, and the convenience and efficiency of the contents ejection mechanism can be improved.

Respectively.

  Here, the stem 3, the lid-like portion 5 and the operation base portion are made of plastic made of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate or the like. The container body 1, the mounting cap 2 and the ball 7 are made of metal. The porous member 8 is made of plastic or metal.

  The basic features of the vibration injection mechanism shown in FIGS. 1 to 3 are that a pressing-type operation member 4 attached to the stem 3 has an annular passage 6d leading to the injection port, and the contents from the stem are swirled into the annular passage. And a spherical body (ball 7) is provided in the annular passage so as to be able to circulate.

  As a result, when the container body 1 is gripped and the operation members 4, 4 ′, 4 ″, 4 ′ ″ are pressed against the skin 9 (see FIG. 2), the valve action part of the stem 3 is opened and the container body 1 The contents of are flown from the respective injection ports 5a, 5e, and 5f into the annular passage 6d through the "valve action portion of the stem 3, the outflow portion of the stem 3, the central passage area 6b, and the spiral passage 6c" while turning. Sprayed onto the surface of the skin 9. As the contents turn, the ball 7 also rotates in the annular passage, and centrifugal force acts on the ball. The operation member vibrates with respect to the skin 9 by the action of the centrifugal force.

  Each of the central passage area 6b, the spiral passage 6c, and the annular passage 6d is configured by covering the groove on the operation base 6 side with the lid-like portion 5, and the lid-like portion 5 is disposed so as not to leak the contents. The operation base 6 is fixed in a liquid-tight or air-tight manner by bonding such as welding or adhesion, or by sandwiching a packing material.

  The position of the injection port 5a is set along the center of the radial width of the annular passage 6d, but may be displaced radially outward or inward within the range of the width. In this case, since the ball 7 approaches the inlet portion of the injection port 5a and does not hinder the flow of the content, the pulsation of the content to be injected can be reduced.

  The passage width of the spiral passage 6c is set narrower than the diameter of the ball 7 so that the ball 7 does not stay in the central passage area 6b in the operation mode.

Here, the operation of the vibration injection mechanism shown in FIGS. 1 and 2 is roughly as follows.
(11) The user holds the container body 1 in the stationary mode and presses the projection 5b of the operation member 4 against the skin 9.
(12) The stem 3 engaged with the operation member 4 is urged toward the container main body 1, the known valve action part is opened, and the operation mode is shifted.
(13) The content of the container body 1 is changed to the annular passage 6d through the path of “the valve action part of the stem 3—the outflow part of the stem 3—the central passage area 6b—the spiral passage 6c—the confluence 6e—the annular passage 6d”. It flows in (see FIG. 2B).
(14) The contents from the spiral passage 6c flow into the annular passage 6d in the direction of forming a swirling flow at the junction 6e. The ball 7 circulates in the annular passage 6d by the force of the swirling flow, and the centrifugal force thereby vibrates the operating member 4 and is transmitted to the protrusion 5b, giving the skin 9 a high rubbing effect and massage effect.
(15) The same amount of content as the amount of inflow from the spiral passage 6c is discharged from the annular passage 6d toward the skin 9 through the injection port 5a.

  The vibration of the operation member 4 is a swing vibration with the user's wrist, the portion where the user grips the container body 1, the hole 2 a, etc. as the apex, and the tip of the projection 5 b having the largest amplitude on the skin 9. On the other hand, a high rubbing effect and a massage effect are exhibited (see FIG. 2A).

  The protrusion 5b shown in FIG. 1 is suitable for a purpose of avoiding the hair and giving a scuffing effect and a massage effect to the scalp at a site with a lot of hair such as the scalp.

  FIG. 3 shows various modifications according to the application.

  In FIG. 3A, instead of the lid-like portion 5, a lid-like portion 5 'having a thick and short convex portion 5c is used. It is suitable for applications that apply analgesics and moisturizers while massaging.

  In FIG. 3 (b), instead of the lid-like portion 5, a lid-like portion 5 ″ having a projection portion 5d having an injection port 5e on the tip side is used. It is injected from near the tip through. It is suitable for drug application to the scalp and can be effectively attached to the scalp rather than the hair of the sprayed contents. Further, since the injection port 5e is not provided at the tip of the projection 5d that comes into contact with the skin, dirt such as sebum and dirt on the skin is not clogged in the injection port.

  In FIG. 3 (c), instead of the lid-like portion 5, the lid-like portion 5 ′ ″ provided with the porous member 8 is used, so that the contents ejected from the ejection port 5 f are transferred to the porous member 8. Since it is impregnated once and then applied, it is difficult to sag. In addition to the use of drug application to the human body similar to Fig. 3 (a), the contents can be used as a wax solution, cleaning solution, polishing solution to protect the surface of cars and furniture. Suitable for surface beautification and surface polishing. In the case of surface polishing, the porous member 8 may be made of a polishing material to secure the content as a lubricating liquid. Further, when the porous member 8 is hard, the rubbing effect and the massage effect are enhanced, and when the porous member 8 is soft, the shape followability to the injected portion is enhanced.

Needless to say, the present invention is not limited to the contents of the vibration injection mechanism according to FIGS. For example,
(21) In order to reduce irritation to the skin 9, the protrusion 5b, the protrusion 5c, and the protrusion 5d are formed of a soft member, and the core portion provided on each lid-like portion is covered with the soft member Formed with,
(22) The valve action part of the stem 3 is not a push-open type but a tilt-open type (tilt-open type) valve action part.
You may do it.
