Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a small manual sprayer used for cologne, etc.

"Problems to be Solved by Prior Art and Ideas" This type of sprayer generally includes a head with a spray nozzle, and when the head is pushed down, a built-in pump is activated, and the contained liquid is discharged from the spray nozzle. It is designed to eject as mist, but in the conventional model, the head rotates freely,
Therefore, there was the inconvenience of having to check the orientation of the spray nozzle each time it was used.

This proposal attempts to eliminate such drawbacks.

"Means for Solving the Problems" The sprayer main body 1 is detachably attached to the liquid container 2 by screwing the inner periphery of the cap-shaped base 11 onto the outer periphery of the mouth 22 of the liquid container 2, and the sprayer main body 1 has the following features: A vertical reciprocating pump 1 is inserted through the cap-shaped base 11.
The head 14 having the spray nozzle 144 is connected to the top of the pump 12, and the head is attached to the guide cylinder 1.
11, and by pushing down the head 14, the pump 12 is operated, and the liquid contained in the liquid container 2 is transferred to the spray nozzle 14.
4, the lower end of the thread 114 of the base body 11 screwed into the mouth 22 is placed below the lower end of the thread 23 provided on the outer periphery of the mouth 22 of the liquid container 2. A stopper 24 is provided vertically in contact with the guide tube 111 and the head 14, and one of the guide tube 111 and the head 14 has a vertical guide groove 112, and the other has a vertical guide groove 112 that is slidably engaged with the guide groove. A protrusion 143 was provided.

``Function'' With the above structure, when the liquid container 2 is filled with liquid and the head 14 of the sprayer body 1 is pushed down, the vertical reciprocating pump 12 is activated and the liquid in the liquid container 2 is pumped to the head. The mist is ejected from 14 spray nozzles 144.

At this time, the direction of the spray nozzle 144 is determined by "the engagement between the vertical protrusion 143 of the head 14 and the guide groove 112 of the base body 11" and "the lower end of the thread 23 provided on the outer periphery of the mouth 22 of the liquid container 2". Stopper 2 installed vertically on
4, abutment and locking of the lower end of the thread 114 of the base body 11.
Therefore, it is always constant.

"Example" The illustrated embodiment will be described below.

FIG. 1 to FIG. 4 are an example of this, and in the figures, 1 is a sprayer main body, and 2 is a liquid container to which the sprayer main body is detachably screwed.

The sprayer main body 1 is provided with a cap-shaped base body 11 that is screwed onto the mouth of a liquid container 2, a vertical reciprocating pump 12 is attached to the base body in a penetrating state, and a head 14 is linked to the top of the pump. , a suction pipe 13 is installed vertically from the pump.

The base body 11 has a thread 11 on the lower inner periphery of the peripheral wall 113.
4, the top wall 115 is recessed downward, a guide tube 111 that opens vertically is erected in the center of the top wall, and a plurality of guide grooves 112 consisting of vertical grooves are formed on the outer periphery of the guide tube. They are installed side by side.

The vertical reciprocating pump 12 has a cylinder 121 vertically disposed from the base 11, a tubular plunger 122 movably inserted into the cylinder from above, and slidably penetrated into the guide cylinder 111, and a spring (see FIG. ) is installed inside the tubular plunger to urge the tubular plunger upward, and a pressure accumulating discharge valve 123 is installed at the upper part of the tubular plunger, and a suction valve (not shown) is installed at the lower end of the cylinder. A head 14 is fitted to the upper end of the plunger, and the upper end of the suction pipe 13 is fitted to the lower end of the cylinder, and the tubular plunger 122 is pushed down with the head 14 against a spring and returned to its original position by the spring. As a result, the liquid in the cylinder is pumped to the head 13 at a predetermined pressure, and the liquid is sucked up into the cylinder through the suction pipe 13.

The head 14 is formed in the shape of a small cap with double inner and outer circumferential walls, and the inner circumferential wall 141 is formed slightly shorter so that the inner circumferential wall is fitted onto the upper end of the tubular plunger 122, and the outer circumferential wall 142 is connected to the guide tube. 111
A longitudinal protrusion 143 is protruded from the rear inner surface of the outer peripheral wall, and the protrusion 143 is slidably engaged with the guide groove 112 at the rear of the guide tube, Furthermore, 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 has a circular opening 22 at the upper end of a body 21 with a non-circular cross section, and a thread 23 is provided around the outer periphery of the opening so that the base 11 of the sprayer main body 1 can be attached and detached. In addition, a stopper 24 is provided that is vertically connected to the lower end of the thread 23, and the lower end of the thread 114 of the base body 11 abuts at the tightening end point to keep the direction of the sprayer main body 1 constant.

Note 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 which the number of guide grooves 112 of the base body 11 is limited to one in the rear part of the previous example. Therefore, although the orientation of the spray nozzle 144 with respect to the base body 11 cannot be changed, it is rather convenient for assembly if no adjustment is required.

Further, if the liquid container 2 has clear directionality by printing or the like, the cross section may be circular.

``Effect of the invention'' According to the present invention, ``the engagement between the vertical protrusion 143 of the head 14 and the guide groove 112 of the base 11'' and ``the lower end of the thread 23 provided on the outer periphery of the mouth 22 of the liquid container 2'' , the vertical installation of the stopper 24 that abuts the lower end of the thread 114 of the base 11 screwed onto the opening 22 of the nozzle 144 allows the nozzle 144 to be mounted in a constant direction with respect to the container 2, so that the content liquid can be kept constant. When replacing the sprayer body 1, when removing and reinstalling the sprayer body 1, it can always be reinstalled in a fixed orientation, which is convenient for use.

In addition, the structure and manufacture are simple and inexpensive, which is extremely useful in practice.
