Description

[Name of invention]

Liquid sprayer

[Technical Field]

The present invention relates to a liquid sprayer (liquid ejector) for ejecting the liquid cosmetic and the liquid as it is or in the form of a mist.

[Background]

Aerosol type liquid sprayers using freon gas are frequently used as sprayers for continuously spraying liquids.

In this aerosol-type liquid sprayer, the aerosol valve is opened by pressing the head of the upper end of the valve pipe which is pressurized from the aerosol-type valve at the upper end of the container and pressurized by the freon gas in the container body. It is ejected through the tube.

This aerosol-type liquid sprayer is extremely convenient because the pressurized liquid is ejected simply by pressing the valve tube of the aerosol-type valve, but the Freon gas used for pressurization is released into the atmosphere, so it rises to an extremely high level and destroys the ozone layer. There is a demand for a passive liquid sprayer capable of continuously ejecting without using freon gas.

In general, as a liquid spray, a pressure sprayer such as that disclosed in Japanese Patent Application Laid-Open No. 63-185475 is used.

In this pressure sprayer, the tubular member equipped with a small diameter normal piston is pushed upwards and installed in a small diameter cylinder equipped with a suction valve that is vertically placed in the container body, and the large diameter piston installed at the top of the tubular member is pressed. It is fitted into a large diameter cylinder vertically installed from the lower surface of the lowering head (hereinafter referred to as a head), and a discharge valve is formed by a valve body erected from the upper end of the tubular member and a valve hole drilled in the upper wall of the large diameter cylinder. Pressing against, the inside of the large-diameter cylinder is pressurized, so that the tubular member descends against the force of the spring, and the liquid is ejected from the sprayer having an opening on the side of the head. The tubular member and the head are raised by closing the valve. At this time, suction will be more than one valve is open, both the cylinder and the liquid in the container body into the tubular suction member.

Such a conventional accumulator has a relatively short spraying time and requires a large number of operation of the pressing head, which is greatly troublesome and can not be replaced with the nebulizer using Freon gas.

The present invention has been made in view of the above situation and its object is to provide a nebulizer with a long spraying time and a simple configuration.

[Initiation of invention]

The present invention relates to a container body provided with a vertically mounted neck portion, a cylinder mounted vertically from the neck portion into a container body, a suction valve provided at a lower end of the cylinder, and a suction valve provided from the suction valve to the bottom of the container body. A suction pipe, an erected wall having an upper end fitted to an upper portion of the cylinder, mounted on an inner side or an outer side of the neck portion, connected to a lower end of the erected wall, and having a predetermined distance between the erected wall and an erected wall from the outside; An enclosed guide barrel, a normal piston fitted into the cylinder so as to be movable, and a stem erected from the piston, a connector attached to an upper end of the stem, a vertically lowered from the connector and the standing wall ( 17) and a sliding tube fitted to be movable up and down within the gap between the guide tube and the guide tube, provided on the stem It relates to a head, and a liquid sprayer comprising a discharge valve equipment at the top of the stem, having a vent in fluid communication with the interior of the stem.

When the head is raised, both the head and the piston are raised to generate a negative pressure inside the cylinder to open a suction valve to suck the liquid in the container body into the cylinder.

In this state, when the head is pressed, the suction valve is closed and the discharge valve is opened by the lowering of the piston, so that the liquid in the cylinder is ejected from the jet port until the piston reaches its lower limit.

And since the sliding cylinder is guided by the guide cylinder, it can be stably operated up and down even if a long stem is used.

Moreover, the spring which raises a piston can also be provided.

It is preferable to use an aerosol valve which has a valve tube connected to the head as the discharge valve and presses the head down to open when the stem and the piston are pressed down.

The aerosol-type valve has a valve body with an upper and lower end open, an elastic body having a first through hole for closing the upper surface of the valve body, a second through hole corresponding to the first through hole, and enclosing the elastic body together with the valve body. The casing is integrally connected, the lower end is closed and the upper end is opened, the head is connected to this upper end, has an annular recess in the middle portion, has a valve hole in the annular recess, and the second through hole of the casing. And a valve tube in which the lower end is inserted into the valve body while the first through-hole of the elastic body is inserted into the valve body and the elastic body is fitted into the annular recess, and a spring having the valve tube pushed upward can be preferably used. .

The casing may be formed of a metal plate such as aluminum, but more preferably, a casing made of synthetic resin is fitted to the upper portion of the valve body.

Moreover, the following liquid sprayers are mentioned as another structure for achieving the said objective. It is built up from the container body equipped with the neck part installed, the outer cylinder part detachably attached to the neck part and installed vertically down into the container body, the inward flange bottom wall attached to the lower part of the outer cylinder part, and the inward flange bottom wall. An inner cylinder portion located in the outer cylinder portion, a suction valve provided in an upper portion of the inner cylinder portion, a suction pipe vertically lowered from the lower end of the inner cylinder portion to the inner bottom of the container main body, and the inner cylinder portion is fitted in a watertight manner so as to move up and down vertically. A cylinder fitted between the cylinder and the outer cylinder so as to be movable, a discharge valve provided at an upper end of the cylinder, a head having a discharge port communicating with the cylinder via the discharge valve, and the cylinder in a downward direction with respect to the inner cylinder; It is a liquid sprayer with a force spring.

Also in this configuration, the aerosol valve as described above can be used as the discharge valve.

When the head is raised with respect to the container body, the cylinder is raised and the inside thereof is negatively pressured so that the liquid in the container body flows into the cylinder through the suction valve.

Then, when the head is released, the cylinder is pressurized downward by the spring, so that the liquid in the cylinder is pressurized.

In this state, when the head 37 is pushed down, the discharge valve opens and the liquid in the cylinder is ejected from the ejection hole. When the head is released, the discharge valve closes to stop spraying, but if the head is continuously pressed, spraying continues until the operating member 20 reaches the bottom as shown.

And since the sliding cylinder is guided by the guide cylinder, it is possible to stably operate up and down even if the stem length becomes long.

An embodiment of a liquid sprayer having a discharge valve 45 is provided.

It will be described in detail below.

In FIG. 1 and FIG. 2, 1 is the container body in which the neck part 4 was erected from the body part 2 through the shoulder part 3, and the outer part of the neck part 4 is screwed.

In the container body 1, the cylinder 9 is vertically lowered from the neck 4 and is installed. The cylinder 9 has a first outward flange 6 at its upper end and is vertically lowered into the container body 1 by fitting the outward flange 6 to the upper end of the neck 4.

The cylinder 9 has a suction valve 7 in its lower end and is provided with a suction pipe 8 which extends from the suction valve 7 to the bottom of the container body 1. The cylinder 9_ has an outer diameter smaller than the inner diameter of the neck portion 4 and has a through hole 10 for preventing negative pressure in the container body 1 at the upper portion thereof.

Not shown, a thin tube portion having elasticity from the inner circumference of the packing 11 sandwiched between the top surface of the container body 1 and the bottom surface of the first outward flange 6 of the cylinder 9 (hereinafter referred to as a thin barrel portion). (15) is lowered vertically, and the thin barrel (15) is fitted to the upper part of the cylinder (9) so that the through hole (10) is clogged and the outside air only when the inside of the container body (1) is negatively pressurized by the liquid reduction. It is closed inflow.

On the other hand, the standing wall 17 is screwed on the outer surface of the neck 4 of the container body 1. The standing wall 17 has an inward flange 16 at its upper end and the outward flange 6 between the top face of the neck 4 via the packing 11 with the inward flange 16 therebetween. The cylinder 9 is fixed by the clamping.

The guide cylinder 20 is erected from the bottom of the standing wall 17 via the gap retaining plate 18. The guide cylinder 20 surrounds the standing wall 17 from the outside and stands at regular intervals between the standing wall 17 and the standing wall 17.

In addition, a piston 26 is normally fitted in the cylinder 9 so as to be movable.

This normal piston 26 has a communication hole in the center portion, and communicates with this communication hole so that the stem 27 is erected. On the upper end of the stem 27, a connecting body 28 on an outward flange is placed, and on the outer circumference of the connecting body 28, the sliding cylinder 29 is vertically lowered, and the sliding cylinder 29 is provided as the standing wall ( 17) is fitted in the gap between the guide barrel 20 and the shanghai movable.

In addition, the fitting tube 30 is erected at the inner circumferential portion of the connecting body 28 on the outward flange.

In the illustrated example, the second guide cylinder 35, which is fitted with the short cylinder 12, which fits on the upper surface of the inner circumference of the outward flange 6 of the cylinder 9, is erected and attached thereto. The stem 27 is inserted in the inside.

The head 40 is fitted over the stem 27. The head 40 is formed in a cap shape and has a blowout hole 43 at an upper side thereof. This jet hole 43 is comprised so that a liquid may be sprayed in a spray form.

The upper inner surface of the stem hole 27a of the stem 27 is closed by the discharge valve 45. In the illustrated example, the holding cylinder 47 equipped with a through hole communicating with the ejection hole 43 from the top plate 46 fitted to the upper portion in the head 40 is vertically lowered and the holding cylinder ( 47) The upper cylindrical portion is fitted into the inner surface so that the lower surface becomes a spherical portion and the elastic cylindrical portion 48 having a slit as a liquid passage at the bottom thereof contacts the upper surface of the stem 27 whose outer peripheral surface is tapered in the bottom portion thereof. It is.

A member 50 is fitted into the bottom of the cylinder 9 to prevent the ball valve 7a of the suction valve 7 from freely moving.

When the head is raised, the piston 27 rises in the cylinder 9 and the inside of the cylinder 9 below the piston 26 becomes negative pressure. Therefore, the suction valve 7 opens and the liquid in the container body 1 It is sucked into the cylinder 9 by the suction pipe 8.

Subsequently, when the head 40 is pressed, the suction valve 7 is closed, and the liquid in the cylinder 9 below the piston 26 is no longer avoided, so that the pressure is high and the discharge valve 45 is opened to open the liquid in the ejection hole 43. Is ejected.

The present embodiment has the above-described configuration. Since the head 40 and the piston 26 can be sprayed by raising the head 40 and the piston 26 as it is, the cylinder 9 and the stem 27 are properly adjusted. In addition, the spraying time can be increased, and the sliding cylinder 29 is vertically connected to the stem 27 so that the sliding cylinder 29 moves up and down between the standing wall 17 and the guide cylinder 20. Since it is equipped to move, even if the stroke of the normal piston 26 with respect to the cylinder 9 is enlarged, the normal piston 26 and the member connected to the cylinder 9 with respect to the cylinder 9 do not rattle when it raises, and can spray smoothly accordingly. .

The second embodiment shown in FIG. 3 is a retainer having a through-hole in which the discharge valve 45 is vertically lowered from the top surface 46 fitted to the upper inner surface of the main wall 41 of the head 40 in the first embodiment. An annular valve body 57 having a cross section is formed by inserting the upper half of the clamping cylinder 55 having the lower half as a large diameter into the cylinder 47 and attaching the inner half of the clamping plate 56. The upper surface of the stem hole 27a is closed by lowering the upper portion vertically and by the lower surface of the upper portion of the elastic spherical surface formed by the lower portion of the valve body.

This embodiment also has the same effect as the first embodiment.

Example 3

As shown in FIG. 4, this embodiment has the same configuration as in the first embodiment. In the first embodiment only the standing wall 17 is screwed to the outside of the neck 4, but in this embodiment the standing wall 17 is arranged inside the neck 4.

In addition, the guide tube 20 connected to the lower end of the standing wall 17 and standing up at regular intervals between the standing wall 17 and the standing wall 17 also has a neck portion ( It is located outside of 4) but in this embodiment it is located inside of neck 4.

A screw barrel connected to the upper end of the guide cylinder 20 and vertically lowered therefrom is provided so that the screw cylinder is screwed onto the neck portion 4.

In the cylinder 9, the piston 26 is normally fitted so as to be movable.

The stem 27 stands up from the piston, the stem 27 stands up, and the aerosol valve 45 having a head in the upper part of the stem 27 is enlarged and attached. An example of this valve is shown in FIG.

A valve body 66 having an outward flange 65 and an elastic body 67 having a first through hole for closing the upper surface thereof are surrounded by a metal casing 68 that passes through the second through hole, and are integrally connected to each other. A valve tube 71 having an annular recess 69 and a lower end surface of the valve hole 70 drilled in the annular recess, through which the first through hole and the second through hole are inserted. The valve hole 70 is closed by the inner wall surface of the through hole of the elastic body 67 and the valve tube 71 is pushed upward by the spring 72. The valve hole 70 and the elastic body ( 67 forms a discharge valve. When the head 40 having the ejection hole 43 is inserted in the upper portion of the valve tube 71 and the head 40 is pushed down against the spring force, the elastic body 67 is formed by the lowering of the valve tube 71. (1) Since the periphery of the through hole is bent downward, the valve hole (70) stops being opened and pressed, and when the valve tube (71) rises, the elastic body (67) is also elastically returned to the position shown to close the valve hole (70). It is equipped.

In the case of the aerosol-type liquid ejector, the outflow pipe is vertically provided in the container body 1 in the cylinder portion 66a vertically lowered from the inner wall peripheral portion of the bottom wall on the inward flange of the valve body 66. There is no need.

The upper end of the valve 45 or the stem 27 is normally fitted with a connecting body 28 which protrudes outward from the periphery thereof, and the sliding tube 29 is vertically lowered to the connecting body 28. 29) is fitted into the guide cylinder 20 so as to be movable.

The sliding cylinder 29 is equipped with a plurality of grooves 81 having a lower surface open at the lower end thereof, and the projections to be inserted into the lower outer edges are caught by the protrusions on the inner surface of the upper end of the guide cylinder 20 when the operating member is lifted up. It is equipped to prevent outgoing.

In this embodiment, since the aerosol valve 45 is fitted and attached, the stem 27 or the piston 26 is pushed down simultaneously with the opening of the aerosol valve 45 when the head is lowered for liquid ejection, and the cylinder 9 is pushed down. The valve hole 67 is closed by the inner wall surface of the first through-hole of the elastic body 67 especially when the high pressure liquid therein can be ejected vigorously at the ejection hole and the ejection is stopped before the piston 26 reaches the lower limit. Since the aerosol valve member 45 having a structure that closes the valve immediately, the liquid ejection can be stopped without the liquid flowing down.

The same parts as in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

Example 4

As shown in FIG. 6, the fourth embodiment is the same as the first embodiment in that the standing wall 17 is provided on the outside of the neck portion 4 and screwed to the neck portion 4, and the aerosol valve is provided. In the same manner as in Example 3.

However, the following points differ from Example 1 and Example 3. FIG.

First, in the fourth embodiment, the standing wall 17 has an inward flange 16 at the top and is outwardly flanged between the inward flange 16 and the top surface of the non-part 4 via the packing 11. (6) is inserted and supported. As a result, the cylinder 9 is fixed. In this respect, the same as that of the first embodiment, but in this embodiment, the fitting cylinder 80 stands up at the inner periphery of the inward flange 16 and falls vertically into the cylinder 9 through the end cylinder 12 on the upper portion of the cylinder 9. I have it all. The fitting cylinder 80 has its lower end fitted to the piston 26 and can be pulled out and determines the upper stroke limit of the piston 26. And since this fitting cylinder 80 was integrated with the standing wall 17, the 2nd guide cylinder 35 equipped in Example 1 was no longer needed.

And the connecting body on the outward flange is installed on the top of the stem 27 and the sliding cylinder 29 is vertically lowered outside the connecting body 28 is the same as in the first and third embodiments, but these stems 27, the connection The sieve 28 and the sliding cylinder 29 differ from Example 1 and Example 3 in that they are integrally molded with synthetic resin. Then, the stem 27 is provided by an ordinary fastener 82 mounted on the upper surface of the stem 27 from above so that a hole 81 fitted into the connecting body 28 is fitted to the edge of the fitting hole 81 so that the lower end is caught. The aerosol valve 45 is fixed to the upper surface.

By omitting and integrating such parts, the number of parts can be reduced and manufacturing costs can be reduced.

Next, the aerosol-type valve 45 used in this Example 4 has an ordinary valve body 66 having a larger upper body than a lower body diameter as shown in FIG. 7 and an elastic body 67 having a first through hole for closing the upper surface. ) And the elastic body 67 having the first through hole and the valve body are usually surrounded by a casing 68 made of synthetic resin having a second through hole. That is, the synthetic resin casing 68 has a structure in which the side wall portion 68b is vertically provided around the top plate portion 68a having the second through hole in the center, and the groove is provided inside the side wall portion 68b. The fitting groove is fitted to the valve body 66 by fitting the protrusion provided in the upper outer peripheral portion of the valve body 66 to the groove. Then, the valve tube 71 having the annular portion in the middle and the lower end surface of the valve hole 70 drilled in the annular portion is closed, and the second through hole of the synthetic resin casing 68 and the first of the elastic body 67 are formed. The valve hole 70 is closed by the inner wall surface of the first through hole of the elastic body 67 by inserting it through the through hole and fitting the elastic body 67 to the annular recess. One spring 72 pushes the valve tube 71 upward. As a result, the valve hole 70 and the elastic body 67 form a discharge valve. Then, the head 40 having the ejection hole 23 is fitted over the valve tube 71 and the head 40 is pushed down against the spring force to lower the valve tube 71 so that the elastic body 67 is lowered. 1 As the periphery of the through hole is bent downward, the valve hole 70 stops being opened and pushed down, and when the valve tube 71 rises, the elastic body 67 also elastically returns to the position shown in the figure, thereby closing the valve hole 70. It is equipped to

In this example, unlike the valve 45 of the third embodiment, a casing made of a synthetic resin is used instead of a metal shell, and the casing 68 to the normal valve body 66 is compared with the third embodiment in which the metal casing is riveted and mounted. The fitting of is extremely easy.

In the fourth embodiment, the normal packing 11 without the thin part 15 is used instead of the packing having the thin part 15 in the first embodiment. Other structures are the same as those in the first and third embodiments, and are denoted by the same reference numerals and description thereof is omitted.

Moreover, as shown in FIG. 8, the piston 26 is divided into the piston body 26b of the cylinder part 26a connected to the stem 27, and a piston main body (B) between this cylinder part 26a and the stem 27 is carried out. 26b) may be attached. In this way, the piston body 26b can be easily replaced in accordance with the size of the cylinder diameter.

Example 5

Example 5 is provided with a spring 90 between the standing wall 17 portion and the connecting body of Example 4, as shown in FIG. 9, and the piston 26 together with the head 40 or stem 27. This is to force the spring 90 so that it is always in a raised position.

Therefore, when not in use, the negative pressure preventing through-hole 10 in the container body 1 is blocked by a piston, so that the liquid does not leak from the through-hole 10 even when there is no thin barrel 15.

In addition, as shown by the dashed-dotted line in FIG. 9, the spring 90 may be sandwiched between the fitting cylinder 80 and the piston 26.

In this way, if the piston (26) together with the head (40) or the stem (27) is always in the ascending position with the spring (90), the operation of raising the head (40) or the like is not necessary in the case of repeated spraying operation. This is easy. In addition, when such a spring 90 is provided, the device which locks the head 40 etc. in the down state at the time of conveyance of a container, etc. may be provided. As an example, the head 40 is provided with a vertical groove for attaching the projection of the sliding cylinder to the inner surface of the guide cylinder 20 by installing a projection on the outer surface of the sliding cylinder 29 and a horizontal groove connected to the lower end of the vertical groove. May be pressed to move the projection from the vertical groove to the horizontal groove so as to lock the head 40 or the stem 27.

Example 6

In this embodiment, as shown in FIG. 10, the aerosol-type valve 45 in Embodiment 5 is incorporated in the stem 27, and the valve body 66 is integrally formed to form a part of the stem 27 so that the synthetic resin can be formed. A valve tube 71 in which an elastic body 67 having a first through hole is mounted on the stem 27 by fitting the casing 68 on the stem 27 and the bottom surface through which the valve hole 70 is drilled is closed. Through the second through hole of the synthetic resin casing 68 and the first through hole of the elastic body 67, and fit the elastic body 67 to the annular groove to fit the inner wall surface of the first through hole of the elastic body 67. By closing the valve hole 70, the valve tube 71 is pushed upward by the spring 72 engaged at the end provided in the stem 27.

Since the casing 68 made of synthetic resin is integrated with the conventional fixing cylinder 82 in which the tip is inserted into the fitting hole 81 provided in the connecting body 28, the number of parts is small.

In this way, the number of parts is reduced and mass production becomes easier, thereby reducing the cost.
