Description

INDUSTRIAL APPLICABILITY The present invention is for a button main body portion to be operated for content injection having a content passage and a storage space portion extending downstream thereof, and for content injection which is attached to the storage space portion and communicates with the content passage. It relates to a nozzle and a button for a content injection operation provided with.

In particular, individual intermediate orifices (holes other than the injection hole, in which the cross-sectional area for passing the contents is set to be smaller than either the immediate upstream or the immediate downstream) in the content passages of the button body and the nozzle. , Notch-shaped part, etc.) related to the contents injection operation button.

Further, the present invention relates to a button for a content injection operation in which the nozzle outflow side opening is formed in a tapered surface shape in an inwardly inclined manner on the front side as shown in the figure so that the content is concentratedly injected into the target portion of the external space area. ..

In this way, individual intermediate orifices are formed in the content passages of the button body and the nozzles attached to the outflow side, so that the contents expand and compress over a wide range of the passages to create a soft natural feeling. It is sprayed in a sprayed state or in a cold prevention mode.

Further, the contents that have passed through the button main body are concentrated from the nozzle outflow side opening to the injection target portion such as the external space area and the affected portion to prevent diffusion and are efficiently ejected.

In the present specification, the longitudinal direction of the nozzle attached to the button body is referred to as the front-rear direction, the content outflow side thereof is referred to as "front", and the content inflow side opposite to the nozzle is referred to as "rear". That is, the left side of FIGS. 1 and 3 is "front" and the right side is "rear".

Conventionally, a button for content injection operation has already been proposed, which comprises a button main body used for content injection operation and a nozzle attached thereto, and an intermediate orifice is formed in the content passage of the button main body (Patent Document). 1).

Has been done.

The button body 1, the single nozzle 2, and the double nozzle 3 are made of plastic, and are made of, for example, polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, or the like.

The basic features of the illustrated content injection operation button (button body 1 + single nozzle 2, double nozzle 3) are:
(21) An upstream intermediate orifice 1b is formed in the outflow portion of the content passage 1a of the button main body 1, and the rear end surfaces of the sheath-shaped portion 2a of the single nozzle 2 and the inner sheath-shaped portion 3a of the double nozzle 3 are respectively. Downstream intermediate orifices 2b and 3d are formed in the portion.
(22) Front end tapered surfaces 2e and 3g for concentrated injection are formed in the front end side openings 2d and 3f of the single nozzle 2 and the double nozzle 3.
And so on.

That is, not only the upstream intermediate orifice 1b of the button main body 1 but also the single nozzle 2 and the double nozzle 3 attached to the button main body 1 are provided with downstream intermediate orifices 2b and 3d.

Although not shown, a hole portion as a downstream intermediate orifice may be provided in a peripheral surface portion other than the rear end of each of the sheath-shaped portion 2a and the inner sheath-shaped portion 3a.

By overlapping the downstream intermediate orifices 2b and 3d with the existing upstream intermediate orifice 1b of the button body 1 in series, the contents to be injected passing through the content injection operation button can be reliably and efficiently expanded.・ Compression action occurs.

Further, since the front end tapered surfaces 2e and 3g are formed in the front end side openings 2d and 3f, the contents flowing out from this opening to the external space area are the front ends of the single nozzle 2 and the double nozzle 3, respectively. Concentrated injection is performed on a line in the front-rear direction passing through the substantially center of the central part of the surface.

In the case of the content injection operation button using the single nozzle 2 of FIGS. 1 and 2, the content flowing into the lateral groove-shaped portion 2c of the sheath-shaped portion 2a hits the inner peripheral surface portion of the accommodating space portion 1c and opens on the front end side. Move to part 2d.

In the case of the content injection operation button using the double nozzle 3 of FIGS. 3 and 4, the content flowing into the annular passage portion 3c in the front-rear direction between the inner sheath-shaped portion 3a and the outer tubular portion 3b is , Unlike the cases of FIGS. 1 and 2, the accommodation space portion 1c moves to the front end side opening 3f without hitting the inner peripheral surface portion.

In the case of the content injection operation buttons of FIGS. 3 and 4, the front end portion of the double nozzle 3 is set to be substantially flush with that of the accommodation space portion 1c, and the liquid from the accommodation space portion 1c. No sagging occurs.

The contents injection operation buttons of FIGS. 1 to 4 are used in a state of being attached to a well-known stem (not shown) on the container body side.

When a user or the like pushes down the top surface 1e of the content injection operation button, the entire operation button and the stem integrated with the operation button move downward.

As the stem moves downward, the valve action portion of the stem shifts from the closed state to the open state, and the contents on the container body side flow from the stem into the content passage 1a by the action of the injection gas. .. Of course, the operation itself of this content inflow is well known.

The contents that have flowed into the contents passage 1a are
(31) In the case of the content injection operation button using the single nozzle 2 of FIGS. 1 and 2, "upstream intermediate orifice 1b-buffer space area s1-downstream intermediate orifice 2b-annular passage area s2-lateral groove-shaped portion" 2c-front end side opening 2d "is injected into the external space area by the flow.
(32) In the case of the content injection operation button using the double nozzle 3 of FIGS. 3 and 4, "upstream intermediate orifice 1b-buffer space area s11-downstream intermediate orifice 3d-annular passage area s12-annular passage" It is injected into the external space area by the flow of "part 3c-front end side opening 3f".

It goes without saying that the present invention is not limited to the above embodiments.
(41) Set any number of upstream intermediate orifices 1b, downstream intermediate orifices 2b, 3d and lateral groove-shaped portions 2c (not shown).
(42) In addition to the push-down type, it also applies to the contents injection passage corresponding to various button type operation parts such as tilt type and trigger lever.
You may do so.
