Definitions
- the present invention relates to a roll-on type actuator for an aerosol container.
- Roll-on type skin external products are commercially available in which skin external preparations such as body odor inhibitors and sunscreen agents are applied to the skin via spherical rolling elements. According to this type of external skin product, the contents can be accurately applied to a desired site without soiling the hand, and a massage effect by pressing the skin can also be obtained.
- the roll-on type application tools used for this type of external skin product can be roughly classified into two types: non-aerosol type and aerosol type.
- Non-aerosol-type applicators have a holder that holds a spherical rolling element so that it can roll, and the contents are supplied to the outer surface of the rolling element by tilting or shaking the container body. It has come to be. By pressing the rolling elements against the skin and rolling, the contents can be applied to the target site. Therefore, in the non-aerosol application tool, in order to prevent the contents from being exposed to the outside air, a means for closing the gap between the rolling element and the holder is required at least when not in use.
- an actuator including a spherical rolling element and a holder that rotatably holds the rolling element is made of a metal pressure vessel such as aluminum or tin (hereinafter referred to as “aerosol container”). .)) Is attached to the aerosol container so as to be fitted to the stem protruding from.
- aerosol container a metal pressure vessel such as aluminum or tin
- the aerosol valve is opened, and the content filled in the aerosol container is ejected from the stem and adheres to the outer surface of the rolling element through the ejection hole provided in the holder.
- the contents are prevented from being ejected by the valve of the aerosol container. Therefore, as in the case of the non-aerosol-type applicator, at least when not in use. It is not necessary to close the gap between the moving object and the holder. This increases the degree of freedom in designing the actuator.
- an actuator for example, further improving the rolling performance of the rolling element, preventing the dripping by making the amount of ejected content constant, or preventing the rolling element from jumping out by the force of ejection, etc.
- the present situation is that an actuator that can sufficiently satisfy these problems has not yet been put into practical use.
- Patent Document 1 discloses an aerosol whose problem to be solved is to improve the durability of component parts, facilitate disposal after use, provide a comfortable massage effect, and prevent inadvertent dripping.
- Containers have been proposed.
- a spherical rolling element (ball) is held in a state where a part of the rolling element is exposed to be able to roll, and a rolling element is engaged with the stem protruding from the pressure resistant container.
- a seat which is elastically supported under cooperation is attached.
- the seat is provided with an elastic partition wall that separates the stem from the rolling elements except for the region of the ejection hole at the tip of the stem.
- the elastic partition has an arch-shaped receiving surface that is convex upward, and a plurality of protrusions are formed integrally with the elastic partition on the upper surface.
- the elastic partition wall elastically supports the rolling element by the receiving surface and the protrusion, so that a large vertical motion of the rolling element is ensured, a comfortable massage effect is obtained, and inadvertent It is said that the effect of preventing dripping is also obtained.
- a rolling element is accommodated between a holder and a receiving seat, and is held in a state where it can move greatly up and down by elastic deformation of an elastic partition provided in the receiving seat. That is, the gap between the inner surface of the holder and the outer surface of the rolling element changes variously depending on how the rolling element is pressed. Therefore, the contents are excessively supplied to the widened gap, and the contents overflow from the opening edge of the holder, or when the rolling element is pushed hard, the elastic partition is greatly deformed, and the gap around the ejection hole at the tip of the stem becomes large. There is a possibility that unevenness may occur in the supply amount of the content, such as the content being blocked and not being sufficiently supplied.
- the seat is molded separately from the holder by a resin material that is more elastically deformed than the holder, it becomes difficult to liquid-tightly seal the joint between the holder and the seat. In addition, liquid dripping may occur from the gap.
- An object of the present invention is to provide an aerosol container actuator that can reliably prevent the moving body from popping out.
- an actuator for an aerosol container includes a rolling element having a spherical outer surface and a rolling element in a state where a part of the rolling element is exposed in a recess having a spherical inner surface.

- the rolling elements do not hinder rolling, and the rolling element always rolls smoothly with constant lightness. . Since the spherical bulge has no directionality, non-uniformity of the rolling property due to the rolling direction does not occur. Furthermore, the spherical bulge provided along the opening edge of the recess also serves to prevent the rolling element from jumping out of the opening surface of the recess.

Since the gap with the surface is always kept constant, the ejection amount of the contents is stabilized, and the adhesion amount of the contents to the outer surface of the rolling element is equalized. Further, the rolling property of the rolling element is improved by the point contact between the spherical bulge and the outer surface of the rolling element. Furthermore, the spherical bulge provided along the opening edge of the recess prevents the rolling element from jumping out of the opening surface of the recess.
