Description

[Detailed description of the invention] The present invention relates to an improved injection button body in which a cap and a button are combined and handled as one unit, and which ensures that the button assembled in the cap can be removed from the top and bottom, and its production. The purpose is to facilitate operations and effectively prevent careless operations.

Below, the drawings showing the embodiments of the present invention will be explained.
A is a cap that includes a lower outer annular cylindrical part 1 for fitting onto the valve structure or end side of the pressure vessel B, an inner cylindrical part 3 having a button insertion hole 2 inside this annular cylindrical part, and these inner and outer cylinders. A concave part 4 that is identical and opens diametrically upward from the upper edge of the part.
It has a structure in which the chevron-shaped bulges 5, 5 are placed opposite each other across the diameter line to create a powerful structure.

An arbitrary number of small inward protrusions 1b are provided on the inner circumferential surface of the lower opening 1a of the outer annular cylindrical portion 1, and this cap A can be attached and detached from the winding portion 6 on the proximal end of the valve structure. When they are pressed and fitted together, they are locked to the lower side of the winding part 6 to prevent accidental detachment.

The inner cylinder part 3 has the button insertion hole 2, for example, a hole having a different shape from the outer shape of the button C, and prevents the button C from freely rotating, thereby fixing the injection direction after the button is attached.

The inner walls 5a, 5a of the chevron-shaped bulges 5, 5 and the inner cylinder part 3 are made into the same body and have a downward stroke within the combined height to accommodate the button B in a vertically movable state, and the inner wall 5a, 5a may be used as a guide when the button is moved by narrowing the distance between them.

An arbitrary number of thin elastic tongue-like pieces 7 are attached to the lower edge of the inner cylinder part 3.
... is inwardly inclined and protrudes from the insertion hole surface, and inserts 7L2.
Forcibly insert button B while expanding it against the soft elasticity,
The restored elastic tongue 7 lightly catches the lower edge of the button B to prevent it from falling freely after being attached.

Since it is a thin tongue-like piece, it can be easily bent during insertion, and even if it is tilted inward for reliable reception, it will not hinder the insertion operation, and it will not interfere with the insertion operation. It is convenient for manufacturing due to error dimensions, etc.

Reference numeral 8 denotes a horizontal frame portion which is formed into the same body by crossing the recessed portion 4 from the inner walls 5a, 5a of the chevron-shaped bulging portions 5, 5, and is inserted into the insertion hole 2.
It is provided above the button B to lock a part of the front side of the button B to prevent it from coming off from the cap A.

Further, the horizontal frame portions 8 may have a structure in which they each protrude a certain length from the opposing inner walls 5a into the recessed portions 4, or they may be provided so as to protrude from one inner wall and have their tips close to the other inner wall. It may have a similar structure.

The recessed part 4, which has an open upper surface and diametrical end, is divided into left and right parts by the horizontal frame part 8, and one side of the wide opening extending from the upper surface of the recessed part to the rear end is provided with an operation finger opening 9 for pressing down. On the other side, a button nozzle is opened to form a discharge port 10.

As mentioned above, the horizontal frame part 8 prevents the button from slipping out, protects a part of the button from the outside and prevents it from being operated by an unexpected external impact, and also allows for accurate positioning for button operation. bring about.

As described above, the present invention provides several thin elastic tongue-like protrusions 7 on the lower edge of the inner surface of the inner cylinder part 3 having the button insertion hole 2 therein.
The button C can be inserted into the button insertion hole by a structure in which a horizontal piece part 8 is provided to prevent the button from coming off, which is housed in the inner wall 5a of the bulge above the recessed part 4.
When inserted, the tongue-like protrusion 7 that inclines inward and protrudes from the hole surface can be bent using the thin elasticity of its own body, making it extremely easy to insert and install, and after insertion, the tongue itself returns to its previous state. The lower edge of the button can be held by the button, and the inner cylinder has a ring-shaped retaining protrusion on the inner periphery as in the past, or a split groove in the inner cylinder to give the cylinder itself expansion elasticity. It has a small protrusion shape, making it easy to shape, and its soft elasticity makes it easy to fit, making it ideal as a holder for extremely light weight buttons.

Further, the horizontal frame portion 8 prevents the button C from slipping out without causing any hindrance to the operation of the button, and can protect the button from inadvertent external shocks.
