Description

[Detailed description of the invention] The present invention relates to a squeeze-type injector that squeezes an elastically deformable container body and injects the content liquid under pressure. It is an object of the present invention to provide a direct switching injector that can switch and emit mist in the form of a water column.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, 1 is a container body; 2 is a container body;
is an injection head attached to the mouth of this container body, 3
numeral 4 is a block-shaped sealing part fitted and fixed in the injection head 2, numeral 4 is a mist and direct switching plug attached to the top of the injection head 2, numeral 5 is a cap, and each of these parts is molded and manufactured from a synthetic resin material. Ru.

The container body 1 is made of a soft synthetic resin material, and its body 6 has elasticity. Therefore, by squeezing the body 6, the stored liquid can be pressurized and injected from the mouth. Reference numeral 7 denotes a mouth portion and a neck portion, and a thread 8 is formed on the outer circumferential surface. Reference numerals 9 denote cap anti-slip protrusions provided at intervals in the circumferential direction.

The injection head 2 has a cap-like shape,
An outward flange 11 is protruded from the outer periphery of the intermediate portion of the peripheral wall 10, and the upper part of the peripheral wall 10 is inclined upwardly, and a nozzle hole 12 is formed on the front side of this inclined peripheral wall, and further on the rear side of the top wall 13. A mounting hole 14 into which the switching plug 4 is inserted is opened, and an outward flange 11 is provided.
is mounted on the top of the container body, and the peripheral wall 10 below the flange 11 is fitted into the neck portion 7 to be attached to the mouth portion of the container body 1. Top wall 1 with the mounting hole 14 opened
3. The back surface of the rear side hangs down somewhat downward in a stepped shape.
5 is a locking protrusion provided on the inner periphery of the peripheral wall 10, 1
Reference numeral 6 denotes a ring-shaped engagement protrusion provided on the outer surface of the inclined peripheral wall around the nozzle hole 12.

The sealing part 3 has a thick disk shape, and has a water injection hole 17 in the front part and a ventilation hole 18 in continuous communication with the mounting hole 14 in the rear part, respectively. The water injection hole 17 has a large diameter mounting hole in the lower part from near the top, and a water injection pipe 19 that hangs down to the inner bottom of the container body 1 is inserted and fixed into this mounting hole.
The injection head 2 is mounted so that it does not rotate by engaging vertical grooves 20, 20 recessed on both sides of the periphery with vertical strips (not shown) protruding from the inner surface of the upper part of the peripheral wall 10 of the injection head 2, and in this mounted state, the lower surface is engaged. It is held by a stop protrusion 15. In this attached and held state, an injection passage 21 communicating with the nozzle hole 12 is formed between the injection head 2 and the back surface of the top wall 13.

The switching stopper 4 is inserted from the end of the handle 22 in the horizontal direction.
A rod-shaped stopper 23 that is inserted through the mounting hole 14 to the ventilation hole 18 is hung down, and is hook-shaped. Vertical air intake groove 24
is recessed.

The cap 5 has a shape corresponding to the outer shape of the injection head 2, and has a threaded groove 25 formed on the inner periphery of the lower peripheral wall to be threadedly engaged with the thread 8, and when installed, the inner surface of the inclined peripheral wall fits into the engaging protrusion 16. The nozzle hole 12 is reliably closed by pressure contact.

In addition, in the switching plug 4, 26 is an engagement protrusion;
This is to engage with the engagement groove on the inner periphery of the attachment hole 14 to prevent it from coming off. In addition, in the injection head 2, only the front side facing the injection passage 21 of the back stepped hanging part of the top wall 13 with the mounting hole 14 is
It has a structure in which the passage 21 is penetrated so as to communicate with the passage 21.

In the above, when injecting the content liquid in the form of mist, remove the cap 5, align the handle 22 of the switching stopper 4 to the "fog" display position, and enter the container body 1 through the air injection groove 24 as shown in Figure 1. The upper cavity is communicated with the injection passage 21, and the body 6 is compressed in this state. Then, the pressurized liquid is injected into the injection passage 21 through the water injection pipe 19, and the pressurized air is injected from the air injection groove 24 into the injection passage 21, so that they are mixed in this passage 21, become a mist, and are sent to the nozzle. It is ejected from the hole 12.

Next, when injecting the stored liquid directly into a water column,
Turn the handle 22 of the switching plug 4 approximately 90 degrees to "straighten"
Adjust the air intake groove 2 of this switching plug 4 according to the indicated position.
4 is changed in direction so that it does not communicate with the injection passage 21, and then the body portion 6 is compressed. Therefore, in this case, the air is immediately cut off and only the stored liquid is injected from the water injection pipe 19 through the passage 21 and from the nozzle hole 12, so that the stored liquid is injected in the form of a water column.

The other embodiments shown in FIGS. 3 and 4 are as follows:
The sealing part 3 of the embodiment shown in FIGS. 1 and 2 is formed on the injection head 2 itself rather than as a separate member, and the switching plug 4 has a plug body 23 with a large diameter, and the air injection groove 24 is formed on the bottom surface of the switching plug 4. The plug body 23 is recessed in the direction of the handle 22, and the plug body 23 is inserted into the mounting hole 14 made in the center of the top wall 13 of the injection head 2, and the handle 22 is "fog".
The direction of the air inlet groove 24 is changed by switching to "straight" so that the nozzle hole 12 and the ventilation hole 18 are communicated or disconnected.

According to the present invention, the switching plug 4 is connected to the handle 2.
The stored liquid can be selectively injected in the form of a mist or a water column by a simple operation of switching by turning approximately 90 degrees at step 2, which is extremely convenient and can be widely applied. In addition to the injection head 2 and switching tap 4, the parts include a water tap 1.
9 is sufficient, and since they have a simple shape, the structure is simple, and they can be provided at low cost by synthetic resin molding.
