Abstract

PURPOSE:To make it possible to use a fluid injection valve device both in elected and inverted states by forming a space between an external cylinder and an internal cylinder which allows fluid to flow into an upper part of the internal cylinder when the valve device is used in the head-standing state. CONSTITUTION:This fluid injection valve device comprises an external cylinder 4 and an internal cylinder housed in the external cylinder 4 and having a fluid injection valve. A deformable part 19 is provided in a peripheral part of an upper end of the internal cylinder. Between the external cylinder 4 having an opened part 16 for feeding liquid in the middle part and the internal cylinder, a space which allows fluid to flow into an upper part of the internal cylinder through a actually deformed part of the deformable part 19 provided in the peripheral part of the upper end of the internal cylinder, which is on the internal cylinder side when the valve device is used in a head-standing state. At a time when the valve device is used in an elected state, injection fluid is made to flow from the surrounding of a flow passage closing ball 7 which is positioned above a lower part valve seat 15 for the flow passage closing ball 7, so that the fluid can move toward a fluid injection valve housing chamber. As a result, the fluid can reach an injection port of the fluid injection valve under a relatively low resistance. Accordingly, either in the elected state or the inverted state, the fluid injection flow passage is opened, and therefore, the fluid can be jetted to the external smoothly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid ejecting valve device which can be used both upright and upside down, and in particular, can 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 that can be used both upright and inverted.

[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 result 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 that it will dissolve in 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. One of the causes is that the upright use of the conventionally used fluid ejection valve device that can be used both upright and upside down,
There is a problem that the flow path closing sphere has to close its valve seat. The first object of the present invention is to solve the above problems. Further, the present invention is a fluid ejection valve device capable of both upright use and inverted use, in a state of upright use, of the flow path closing sphere located above the lower valve seat of the flow path closing sphere. A second object is to allow the jet fluid to flow from the surroundings and move the fluid toward the fluid jet valve accommodating chamber so that the fluid can reach the jet port of the fluid jet valve with relatively little resistance. . Further, the present invention is a fluid ejection valve device capable of both upright use and inverted use, in which the deformable portion provided on the upper end peripheral surface portion of the inner cylinder on the inner cylinder side in the inverted use state. By forming a gap for allowing the fluid to flow into the upper portion of the inner cylinder via the above, the third feature is that the fluid can easily flow from the gap toward the fluid ejection valve accommodating chamber in the upper portion of the inner cylinder. To aim.
