Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an aerosol type foam dispenser, and more particularly to improvement of a nozzle discharge part thereof.

[Prior Art] In a conventional aerosol type foam dispenser, as shown in FIG. 6, a lid-shaped exterior member b is fitted into the mouth of a container body a, and a nozzle c and a pusher are attached to the exterior member. The button d is integrally formed and is formed so as to be pushed down by the elasticity of the arcuate notch e and the exterior member b.
The lower end of the through hole is structured to be engaged with the stem f of the container body a.

In this foam dispenser, when the push button d is pushed as shown in FIG. 6 (c), the nozzle c is slightly tilted and the stem f is pushed down, whereby the contents in the container main body a are pushed into the nozzle c. And is discharged in the form of bubbles from the upper end opening of the nozzle c.

[Problems to be Solved by the Invention] However, according to the above-described conventional foam dispenser, not only the foam-like content remains at the upper end opening of the nozzle c after use and becomes dirty, but also the remaining content is When solidified, the upper end opening of the nozzle c may be blocked when it is used next time, and discharge may be hindered. In addition, since the push button d is provided on one side of the nozzle c, the direction is limited during operation, which is inconvenient to use, and it is difficult to tilt the container body downward to push the push button during use. There was a problem to say.

The present invention has been made in order to solve such a conventional problem, and not only does the bubble-like content not adhere to the upper end opening of the nozzle after use and the direction of the push button is not limited to one side, It is a technical object to provide a foam dispenser that can be easily operated even when the container body is tilted downward.

[Means for Solving the Problem] As a means for solving this technical problem, the present invention provides an exterior member attached to a mouth portion of a container body and a lower end portion pivotally supported by the exterior member. The exterior member has a nozzle member movably fitted therein, and a bridge is erected on the exterior member so as to cross the upper surface of the nozzle member, and the nozzle member has a lower end portion of a through hole for discharging the container body. When the nozzle member is pushed laterally and rotated, the stem is pushed down, and the upper end opening of the through hole is exposed by being released from the bridge. It is a gist that the stem is returned when it is released, and the upper end opening of the through hole is in contact with and hidden by the bridge.

[Operation] When the nozzle member is pushed from the side, the nozzle member is rotated and the stem is pushed down, the upper end opening of the through hole is disengaged from the bridge and exposed, and the bubble-like contents are discharged. On the other hand, when the hand is released from the nozzle member (release of the pressing force) after use, the stem returns, and the upper end opening of the through hole comes into contact with the bridge to be wiped cleanly and concealed. It Further, since the nozzle member can be pressed not only from one side but also from the opposite side, the orientation is not limited during use.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a container main body filled with contents, on which a lid-shaped exterior member 2 is fitted, and an oval hole 2a is formed on the upper surface of the exterior member 2. A substantially gate-shaped bridge 3 is integrally erected so as to straddle the hole 2a. The bridge 3 may be formed separately from the exterior member 2 and attached by means such as fitting. As shown in FIG. 2, the bridge 3 has a protrusion 3a at the center of the upper inner surface.
And a recess 3b is formed facing each other on the inner surface of the lower portion as shown in FIG. Reference numeral 4 denotes a nozzle member which is horizontally long and whose upper surface is slightly curved in an arc shape, has a through hole 4a for discharging in the central portion, and projections 4b are provided opposite to the lower portions of both side surfaces. The protrusion as shown in Fig. 3
4b are respectively fitted in the recesses 3b of the bridge 3, and the slightly expanded lower part of the through hole 4a is set to the stem of the container body 1.
By being fitted to 1a, it is fitted to the exterior member 2 so as to be orthogonal to the bridge 3. At this time, the upper protrusion 3a of the bridge 3 is fitted into the upper end opening of the through hole 4a of the nozzle member 4, so that the protrusion 3a can be smoothly moved in a later-described operation stage. The through holes 4a are preferably designed to have rounded corners.

The foam dispenser according to the present invention is configured as described above,
As shown in FIG. 4, by pushing the upper part of the nozzle member 4 from the lateral direction, the foam-like contents can be discharged. That is,
When the nozzle member 4 is pushed from the side, it rotates about the protrusion 4b, and as shown in FIG. 5, the upper end opening of the through hole 4a comes off the protrusion 3a of the bridge 3 and is exposed to the outside. This is because the stem 1a is pushed down. The direction of pushing the nozzle member 4 is not limited to the direction shown in FIG.
You may push from the opposite direction. That is, the contents can be discharged by pushing from either the left or right (or the front or back) direction. Further, the upper surface of the nozzle member 4 is formed in the arcuate curved surface as described above, and the operation can be performed by pressing any part, so that the nozzle member 4 can be smoothly rotated. In particular, when the container body 1 is tilted downward during use, it is sufficient to operate the container body 1 with one hand while holding the container body 1 with a finger and pushing it.

On the other hand, when the hand is released from the nozzle member 4 after use, the pushing down of the stem 1a is released to stop the discharge of the contents, and the nozzle member 4 is rotated in the opposite direction so that the upper end opening of the through hole 4a is The projection 3a of the bridge 3 is fitted again and stopped. At this time, if the foam-like content is attached to the upper end opening of the through hole 4a, the foamy content is wiped off when the upper end opening of the through hole 4a slides into the bridge 3, The upper end of 4a is covered by the protrusion 3a of the bridge 3. Therefore, the upper end opening of the through hole 4a of the nozzle member 4 is not contaminated by the remaining contents, and the bridge 3
Since it is completely hidden by the projection 3a, the through hole 4a is shielded from the outside air, and the contents are solidified as in the conventional case, and the through hole 4a
It does not block the top end of the.

[Effect of the Invention] As described above, according to the present invention, in the foam dispenser, the bridge is erected on the exterior member fitted to the container body, and the nozzle member is rotatable with respect to the exterior member. The upper end of the through hole of the nozzle member is exposed from the bridge when in use and is hidden by the bridge when not in use. Therefore, after use, the foam-like contents do not adhere to the upper end opening of the through hole, the upper end opening is always kept clean, and it is not blocked by the solidified contents, so that it is always comfortable to use. Play. Further, the pushing direction of the nozzle member is not limited to one side as in the conventional case, so that it is easy to use, and even when the container body is tilted and used, it is easy to operate, which is extremely convenient in use.
