Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a downward ejection head of an ejector.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, a pump having a stem protruding from the upper end is attached to the mouth of a container body, and the push-down jet head is provided on the stem, and the push-down jet head is provided. By pressing down,
There is an ejector that operates a pump to eject liquid or the like in a container body from a nozzle of a push-down ejection head.

By the way, in the downward ejection head of such an ejector,
There is a projecting nozzle that can be folded down.
-144054 publication). By doing so, the ejection direction is defined by the protruding nozzle, which is convenient for use, and there is an advantage that the nozzle is not obstructed by being folded down when not in use.

However, when not in use, the folded nozzle is exposed to the outside, so if it is left for a long time in this state, not only will dust adhere to the outer surface of the nozzle, but also the inside of the nozzle from the rotating base of the nozzle, etc. There is a drawback that the dust penetrates to the inside and the dust is mixed into the jetted liquid or the like at the next time, and the folded nozzle has a drawback that it looks bad.

The present invention seeks to eliminate such conventional drawbacks.

Further, the cover cap 3 may be hinge-coupled to the head main body 1 at a subsequent stage, as shown by a chain double-dashed line in FIG.

Thus, the push-down jet head may be used by being fitted and connected to the stem 51 protruding upward from the pump 5 screwed into the mouth of the container body 4 with the fitting cylinder 11. To obtain the liquid, the liquid is stored in the container body 4, the cover cap 3 is opened, the nozzle 2 is swung forward and advanced, and the head body 1 is pushed down, whereby the pump 5 operates. The liquid in the container body 4 is pressure-supplied from the stem 51 to the nozzle 2 through the flow path 13, and is ejected as mist from the nozzle to the outside. After that, the nozzle 2 may be housed again and the cover cap 3 may be closed.

Part 2. FIGS. 3 to 5 show an embodiment of the invention of claim 2,
It is made of synthetic resin.

The push-down ejection head shown in the drawing has a nozzle housing groove 12 in which the front end is opened forward and the rear end is closed on the upper surface of the head body 1 in which a fitting cylinder 11 for fitting the stem 51 in the center of the lower surface is hung. And the locking edges 1 on both side edges and both front edges of the groove, respectively.
6,16,15,15 are provided in a projecting manner, and a slender spray nozzle 2 having a rectangular cross section is provided in the groove so as to be able to come in and out in a forward direction. The engaging ridges 25, 25 slidably engaged with the engaging edges 16, 16 of the above are provided laterally, and the stoppers 26, 25 that abut against the engaging edges 15, 15 of both front edges of the concave groove at the rear part. 26 is provided in a protruding manner, and claw hooking projection pieces 24, 24 used at the time of sliding in and out are provided at the front end and the rear end of the nozzle 2.

Further, a crank-shaped flow path 13 that opens from the fitting cylinder 11 to the front of the groove bottom is provided at the groove bottom of the concave groove 12, and the flow path is formed on the lower surface of the base end 21 of the nozzle as the nozzle moves forward. A base end flow port 22 communicating with 13 is provided, the upper surface of the head body 1 is covered with a cover cap 3, and the rear portion of the cover cap is integrally connected to the rear portion of the head body 1 via a thin hinge 31.
Engaging means composed of engaging ridges 32, 32 which engage with each other on both sides are provided.

The channel 13 is formed by fitting the groove bottom portion of the groove 12 in the head body 1 as a separate member for the convenience of synthetic resin molding.

The push-down jet head is used by fitting and connecting the fitting cylinder 11 to the stem 51 in the same manner as in the previous example, but operates in the same manner as in the previous example except that the nozzle 2 is slid in and out.
The description is omitted.

Part 3. FIGS. 6 to 8 show an embodiment of the invention of claim 3,
It is made of synthetic resin.

The push-down jet head shown in the drawing has a recessed step portion 14 which is opened from the front surface to one side surface on the upper surface of the head main body 1 in which a fitting cylinder 11 for fitting the stem 51 is provided at the center of the lower surface. The elongated spray nozzle 2 having a square cross section is arranged rearward on the concave step portion, and the vertical shaft 17 is erected at the front end of the concave step portion so that the base end 21 of the nozzle is moved forward by the vertical axis. It is pivotally attached to rotate horizontally.

Further, a crank-shaped flow path 13 that opens from the fitting cylinder 11 to the base end 21 of the nozzle is provided in the groove bottom of the concave groove 12, and the cover cap 3 is put on the upper surface of the head main body 1 to provide a rear portion of the cover cap. Is integrally connected to the rear part of the head body 1 via a thin hinge 31, and engaging means composed of engaging ridges 32, 32 that engage with each other on both sides of the head body 1 are provided.

For convenience of synthetic resin molding, part of the groove bottom portion of the concave groove 12 and the vertical shaft 17 are fitted and integrated with the flow path 13 as separate members. In the figure, reference numeral 18 is a claw recess.

Also in this case, as in the first embodiment, the fitting cylinder 11 is
Although it is used by being fitted and connected to the 51, the operation is the same except that the nozzle 2 is horizontally rotated to move in and out, and therefore the description thereof is omitted.

[Advantage of Invention] According to the inventions of claim 1, claim 2, and claim 3, the push-down ejection head is fitted and mounted on the stem 51 protruding upward from the pump, and the nozzle 2 projects forward. Since the push-down jet head has the above-described configuration, the nozzle 2 can be housed inside the cover cap 3 by closing the cover cap 3 with the nozzle 2 retracted when not in use. The upper surface of the main body 1 can be generally covered, so that even if the unused state is for a long period of time, the nozzle 2 in the cover cap 3 and the upper surface of the head main body 1 around the nozzle should be mixed with the liquid to be jetted. No dust is attached or accumulated, and the nozzle 2 is wrapped in the cover cap 3 and looks good.

Further, even if dust is attached or accumulated on the closed cover cap 3, the dust is transferred to the non-affected zone as the cover cap 3 is rotated outward by opening the cover cap 3. Therefore, the dust does not adhere to the nozzles 2 and the upper surface of the head body 1 around the nozzles, and the cover cap 3 is used at the next jetting of liquid or the like.
Even when the nozzle 2 is opened and closed, the nozzle 2 is moved forward and backward, and the push-down jet head is moved up and down, dust is not mixed in the jetted liquid or the like. Of course, unlike the spout cap, the push-down spout head is not tilted together with the container body, so that dust that has adhered to or accumulated on the cover cap 3 does not fall onto the liquid or the like that is being ejected.

Furthermore, when ejecting a liquid or the like in this way, the nozzle 2 can be advanced forward so that the direction of ejection by this nozzle can be made clear, which is convenient and convenient for use.
