Abstract

PURPOSE:To hold airtightness of a valve in a flow path to secure a contact state by providing a fluid spouting valve mechanism which closes a fluid spouting flow path normally wherein airtightness at the time of contact between a closing ball and a seat opening is held when the flow path of the fluid spouting valve is closed and the flow path can be opened when the valve is used in a normal standing posture and a reverse standing posture. CONSTITUTION:A fluid spouting valve is built into an outer cylinder 4 having a liquid supply flow path, and a contact state between a flow path closing ball 7 and its receiving opening when the fluid spouting valve is closed is secured so that airtightness can be sufficiently held. The flow path can be opened between the outer cylinder 4 and the fluid spouting valve both during normally standing use and reversely standing use, while a fluid spouting flow path 13 can be closed normally. With respect to a center opening of a packing 8 formed of an elastic material built into the outer cylinder 4, the closing ball 7 housed in a space inside the outer cylinder 4 can be closed to supply fluid from a liquid feed flow path provided on the outer cylinder 4 to the fluid spouting flow path 13 and to spout the fluid to outside.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow-out jet valve device which can be used in both an upright position and an inverted position, and more particularly, to be attached to an aerosol container containing a gas gas such as carbon dioxide gas or nitrogen gas. The present invention relates to a fluid ejection valve device capable of both upright use and inverted use.

[0002]

2. Description of the Related Art A conventional fluid ejecting valve device, which can be used both upright and inverted, is provided with a flow path closing sphere and an opening provided in a lower portion of an outer cylinder. , When the opening is closed with the sphere between them, since the surface that closes the opening is funnel-shaped and has an inverted conical shape, the inverted-conical surface and the flow path closing sphere Originally, it is possible to make a geometrical contact so as to maintain airtightness, but in reality, it is difficult to make a gap without any gap. It is necessary to improve the finishing accuracy of the surface of the sphere and the surface of the flow path closing sphere, and the time and labor for the processing have doubled. On the other hand, in order to improve the finishing accuracy of the surface of the sphere, even if all technical efforts are repeated, since the material is a resin molded body, sink marks or distortions may occur in the molding process of the resin molded body. It has been found that it is not desirable to form an exact inverted conical surface shape. Similarly, the same problem occurs on the surface part of the flow path closing sphere that must be brought into contact with the inverted conical surface part, so even if efforts are made to improve the finishing accuracy of the surface, the results will be the same. Is virtually impossible to hope for. In addition, recently, in order to escape from environmental pollution, unlike products filled with liquefied gas that have been used in the past, products using aerosol containers are different from carbon dioxide and nitrogen, which have little effect on environmental pollution. Aerosol containers containing gas such as gas have come to be handled. However, if such an aerosol container is used in an upright state, the contact state between the surface portion of the flow path closing sphere and the surface portion of the inverted conical shape must be ensured so much that it will melt into the content liquid. Otherwise, the compressed vaporized gas contained in the aerosol container may run out, and the aerosol container may become unusable with the contents left in the aerosol container.

[0003]

Therefore, as described above, the aerosol container can be used in either an upright state or an inverted state, and can be used in any state. The fluid ejection valve device which can be used for both is conventionally used. However, it is necessary to improve the contact state between the surface portion of the flow path closing sphere that is difficult to maintain airtightness and the inverted conical surface portion, and in particular, in order to sufficiently maintain airtightness, Although various technical efforts are required, regardless of such technical efforts,
Still, no definitive results have been achieved. The present invention aims to solve the above problems.
