Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a small-sized manual sprayer used for cologne and the like.

"Problems to be solved by conventional techniques and devices" This type of atomizer is generally equipped with a liquid container under the atomizer body, and the atomizer body is equipped with a head with a spray nozzle that is vertically guided by a guide member. , By pushing down the head, the pump of the sprayer main body is activated, and the liquid in the liquid container is ejected as mist from the spray nozzle. Since it rotates, it is inconvenient to check the direction of the spray nozzle each time it is used.

By the way, such an inconvenience can be achieved by appropriately controlling means for preventing free rotation of the head between the head and the guide member of the head.

However, with this alone, the orientation of the spraying head can be adjusted to attach the sprayer body to the liquid container during production, or to reattach the sprayer body once removed from the container body when replenishing or replacing the content liquid. There is an inconvenience that it is not constant and must be adjusted each time.

The present invention is intended to solve such a problem.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a liquid container 2 detachably attached to a lower surface of a sprayer main body 1, and the sprayer main body 1 includes:
A cap-shaped base 11 that is connected to the mouth 22 of the liquid container 2 is provided, the vertical reciprocating pump 12 is installed in the base in a penetrating state, and a guide cylinder 111 that surrounds the vertical reciprocating pump is raised. Further, a spray nozzle is provided on the vertical reciprocating pump 12.
By mechanically and fluidly linking the head 14 having 144, and by slidably fitting the head to the guide cylinder 111, the vertical reciprocating pump 12 is operated by pushing down the head 14. In a small-sized manual sprayer configured to spray the liquid contained in the liquid container 2 from the spray nozzle 144, a vertical engaging groove 25 is provided on the outer periphery of the mouth 22 of the liquid container 2, and a lower portion of the outer periphery of the mouth is provided. Around the inner surface of the peripheral body 113 of the base body 11 of the sprayer main body 1 to engage with the engaging groove 25 and the engaging ridge 26 respectively.
116, 117 are provided, and the guide cylinder 111 and the head 14 are provided.
A guide groove 112 composed of a vertical groove on either one of
On the other hand, a vertical protrusion 143 slidably engaged with the guide groove is provided.

"Operation" Because of the above-mentioned configuration, when the liquid is properly stored in the liquid container 2 and the head 14 of the sprayer main body 1 is pushed down, the vertical reciprocating pump 12 operates and the liquid in the liquid container 2 is moved to the head. The atomizing nozzles 144 of 14 ejects as mist.

At this time, the direction of the spray nozzle 144 is the vertical protrusion 143 of the head 14.
And the guide groove 112 of the base 11, and the positioning of the sprayer main body by the engagement groove 25 of the mouth 22 of the liquid container and the engagement ridge 116 of the base 11.

"Example" Hereinafter, the illustrated example will be described.

FIG. 1 to FIG. 4 show one example thereof, and in FIG.
Is a sprayer main body, and 2 is a liquid container in which the sprayer main body is detachably fitted.

The sprayer main body 1 is provided with a cap-shaped base body 11 to be fitted into the mouth portion of the liquid container 2, a vertical reciprocating pump 12 is provided in a penetrating state of the base body, and a head 14 is linked to the pump. The suction pipe 13 is hung from the pump.

The base body 11 has a longitudinal engaging protrusion 1 at an intermediate portion of the inner surface of the peripheral wall 113.
16 and each of the lateral edges of the engaging projections 117 are provided at the lower edge, and the top wall 115 is retracted downward, and the guide tube 111 that opens vertically is set up in the center of the top wall. A plurality of guide grooves 112, which are vertical grooves, are arranged side by side on the outer circumference of the guide cylinder.

In the vertical reciprocating pump 12, a cylinder 121 is hung from the base 11, a tubular plunger 122 is movably inserted into the cylinder from above, and the guide cylinder 111 is slidably pierced and the cylinder 121 is inserted into the cylinder. A spring (not shown) is installed to urge the tubular plunger upward, and a pressure accumulating type discharge valve 123 is provided in the upper part of the tubular plunger and a suction valve (not shown) is provided in the lower end of the cylinder. Then, the head 14 is fitted on the upper end of the tubular plunger, and the upper end of the suction pipe 13 is fitted on the lower end of the cylinder.
The liquid in the cylinder is pumped to the head 14 at a predetermined pressure by pushing down 2 against the spring with the head 14 and returning by the spring, while sucking up the liquid in the liquid container 2 to the pipe 13. It sucks up into the cylinder through.

The head 14 is formed in the shape of a small cap having double inner and outer peripheral walls, the inner peripheral wall 141 is formed slightly shorter, and the inner peripheral wall is fitted to the upper end of the tubular plunger 122, and the outer peripheral wall 142 is formed into the guide tube. 111 is slidably fitted to the outer periphery of the outer peripheral wall of the outer peripheral wall 111, and a vertical protrusion 143 is provided on the rear portion of the inner surface of the outer peripheral wall so that the vertical protrusion is slidably engaged with the guide groove 112 at the rear of the guide cylinder. A spray nozzle 144 communicating with the inner peripheral wall 141 is provided on the front surface of the peripheral wall.

The liquid container 2 is provided with a circular mouth portion 22 at the upper end of a body portion 21 having a non-circular cross section, a vertical engaging groove 25 at the outer periphery of the mouth portion, and a lower portion of the outer periphery of the mouth portion. The ridges 26 are provided so that the bases 11 of the sprayer main body 1 are non-rotatably and removably fitted to each other.

It should be noted that each of the above-mentioned members may be appropriately molded from synthetic resin.

FIG. 5 shows another example of the sprayer main body 1. In this case, in the case of the previous example, the guide groove 112 of the base 11 is limited to one rear portion. Therefore, although the direction of the spray nozzle 144 with respect to the base 11 cannot be changed, it is rather convenient in terms of assembly unless adjustment or the like is necessary.

Further, the liquid container 2 may have a circular cross section as long as it has a clear directionality due to printing or the like.

According to the present invention, the vertical projection 143 of the head 14 and the guide groove 112 of the base 11, the engagement groove 25 of the liquid container mouth 22, and the engagement projection 116 of the base 11. Since the sprayer main body 1 can be attached to the liquid container 2 with the direction of the spray nozzle 144 always kept constant, the sprayer body 1 can be replenished with the content liquid even during the mounting at the time of production. Even if the sprayer main body 1 that has been once removed is replaced and then re-mounted, it can be mounted very easily in a fixed orientation without any trouble, which is convenient and convenient to use.
