Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a 7' (Spencer) system in which the liquid in the container, such as insecticide, neutral detergent, or cosmetic liquid, is drawn up into the cylinder by the sliding of the piston, and then forced out under pressure. Regarding fb.

- This type of disker is attached to the container via the cap with the piston attached to the head and the cylinder attached to the cap. Then, by pressing the head downward, for example, the piston is lowered together with the head, By pressing the head, the piston slides, which causes the liquid to flow out.Therefore, this type of dispenser is designed to allow the liquid to flow out of the head before it is used. It is necessary to package and transport the product in such a way as to prevent it from being compressed.Also, when it is displayed at a store, it is necessary to prevent the liquid from flowing out due to pressure on the head caused by carelessness or falling. It is required to apply a so-called virgin lock to prevent unnecessary or careless suppression of the head before the start of use.

Even for new users, it is required to provide a so-called child grip, which is a locking means to prevent the head from being depressed when not in use and protect children and children from accidents.

The object of the present invention is to provide a gas dispenser that has a parnon lock and is childproof.

Embodiments of the present invention will be described in detail below with reference to the drawings.

#l! As shown in FIG.
is slidably arranged.

The piston 14 has a skirt-like seal 16. at its lower end and intermediate portion. The skirt seal 16 slides along the small diameter portion of the cylinder 110, and the skirt seal 11 slides along the large diameter portion of the cylinder.

Here, the skirt-like seal 18 acts as a seal for preventing negative pressure.

The piston 14 also has a passage 19 formed coaxially with the piston, and this passage is defined by the movable piston and the fixed cylinder 12 and communicates with the variable space 2011C. A nine flow path 21 is formed below the cylinder 12 in communication with the cylinder, and a secondary valve 22 is disposed within the flow path. - The next valve 22 is prevented from leaving the flow path 21 by six valve retainers 23 formed at equal intervals along the inner circumferential surface of the cylinder 12. - It is not to be said that the valve is not limited to the form of the embodiment, and may have other shapes such as a ball valve or a plaid valve. In addition, four round negative pressure holes 25 are formed along the horse surface at the lower end of the large diameter part of the cylinder 120 to allow outside air to flow into the container so as to prevent negative pressure inside the container. has been done. A cap 24 is fitted to the upper end of the cylinder/12, and a suction pipe 25 is fitted to the lower end. The cap 24 has a female threaded portion 21 on its inner surface, and is screwed onto the opening of the container 2 containing a liquid, such as an insecticide. The attachment of the cap 24 to the container 29 is not limited to screwing, but may also be done by other methods, such as press-fitting. In the case of screw-fitting, the advantage is that the container can be replaced easily, and in the case of press-fitting, the processing of the cap is cylindrical. It has the advantage of being a tower.

The cap 24 also has an annular protrusion 28 at its upper end that is formed concentrically with the cylinder 12. A lock #I30 is formed (only one is shown in FIG. 2).

As shown in FIG. 2, the outer circumferential surface of the central protruding portion 21 of the locking @5oFi is formed by a raised shape.As will be described later, the horizontal embankment portion 32 is formed by a strut for preventing the head from rising. Δ, the vertical raised portion 33 acts as a stop for preventing the rotation of the head. The nine locking groove 30 has a triangular notch S5 in which a horizontal embankment is formed in the nine portion 32. The number of locking grooves 30 is not limited to two, but at least one is sufficient.

Additionally, the cap 24 has 92 locking protrusions 36 spaced apart by 180 degrees, as shown in FIG. The locking protrusion 36 is formed in a shape such that its upper part is tapered, so that the locking protrusion 36 is locked to the locking groove when the corresponding locking groove of the i4-gin ring (to be described later) moves the virgin ring, for example, in the pushing direction of the piston. (Figure 3).

Further, as shown in the first WA, the cap 24 has a bottomed hole 38, through which the piston 14 extends. The piston 14 is biased upward by a compression coil spring 40 disposed within the cylinder 12, and its raised position is set by the skirt seal 18 coming into contact with the lower surface of the character fx4. The upper end of the spring 40 is in contact with the lower end of the inner wall f42 in the cylinder 12.

A head 46 having a nozzle 44 is mounted on the upper end of the piston 14, as shown in FIG. 1, and this head moves up and down integrally with the piston. Further, the head 46 extends directly and communicates with the flow path 48 and the nozzle 44.
Nine horizontal flow paths 52 that communicate with the outside air through the outflow holes 50 of the
It has Furthermore, a cylindrical body 54 whose lower end is open is integrally molded with the head 46. As can be clearly seen in FIGS. 4 and 5, the barrel 54 has two retaining protrusions 56 on its inner circumferential surface spaced apart by 180 degrees, and these retaining protrusions are formed on the protrusion 28 of the cap. It has a triangular portion 58 at its upper end that can be locked into the triangular notch 35 of the nine locking grooves 32. As shown in FIG. 5, when the triangular portion 51 is locked in the notch 35, the vertical bulge surrounding the locking groove 30 of the engaging protrusion 56 comes into contact with the head 4# against the character fxa. Further rotation of is prevented. The tab IJ acts as a stop Δ for preventing the head 46 from rotating.

Rectangular windows 60 for confirming the engagement between the engagement protrusion 56 and the engagement groove 30 are formed on the head 46 at a distance of 180° from each other. Further, inverted triangular indexes 62 are formed on the inner circumferential surface of the head 46, spaced apart by 180 degrees. The center lines of the triangular portion 58, the window 60, and the index II2 are then aligned. Furthermore index 6
On the left and right sides of 2, signs indicating the direction of rotation of the head 46, such as clos@, ep@n, etc., are drawn.

As can be clearly seen from FIG. 4, the head 4C has a skirt-shaped seal 64 at the lower end of its outer circumferential surface to prevent liquid leakage and voltage build-up in the container when the dispenser 10 is knocked down.

Furthermore, the dispenser 10 is unnecessary before the start of use.
A rounded virgin ring 66 (see Figure 1) is provided to prevent the head 46 from being pressed inadvertently. This virgin ring 6c is disposed between the cap 24 and the head 46 and acts to lock the head against the character fJfc. As shown in FIGS. 6 and 7, the virgin ring 66 has a pair of locking protrusions 68 spaced apart by 180 degrees on its inner peripheral surface. The locking protrusion 68 is arranged in one direction in the moving direction of the piston 14 and in the pressing direction of the tb head 46.
When the virgin ring 6σ is pressed, it is formed in a shape that locks into the window 60 of the head and prevents the head from rotating. Note that during locking, the locking protrusion 68 temporarily deforms inward in the radial direction. The locking protrusions 68 are formed into a rectangular shape with a triangular cross section and a shoulder portion 70.

The locking protrusion 68 is also formed slightly smaller than the window 60. Therefore, when the locking projection 68 is locked to the window 60, the movement of the locking projection in the rotational direction is obstructed by the window.
Zero rotation is prevented. The tab window g#F;j acts as a locking button.

Further, the lower edge of the window of the head comes into contact with the shoulder 10 of the locking projection 68, thereby additionally preventing the head from rising relative to the virgin ring (see FIG. 1). Furthermore, the virgin ring gg has nine pairs of locking grooves 72 at its lower end, which are spaced apart by 90 degrees from the locking protrusion 68. The locking #I72 can be used as long as it has a shape that can be locked on the locking protrusion 36 of the cap (see FIGS. 2 and 3) when the virgin ring 6C is moved in the direction of suppressing the head 46. The locking groove 72 of the virgin ring, which is not limited to a through hole such as the above, is locked with the locking protrusion 36 of the cap, thereby preventing the per-thin ring 660 from rotating with respect to a certain cap 24. Furthermore, as described above, the locking protrusion 68 of the shin ring is locked in the head window 60, which is a locking groove, thereby preventing the head 46 from rotating relative to the virgin ring. As a result, rotation of the head 46 relative to the cap 24 is prevented via the virgin ring 66. The head 46 is prevented from rising because the locking protrusion 5I is locked with the lock #$36 of the cap. The virgin ring 6d is provided with a lever 74 integrally formed through the breaking edge IJ, and the lever is broken from the virgin ring along the breaking edge by rotating in the direction of the arrow shown in FIG.

As shown in FIG. 1, an annular valve seat 7Ll is integrally formed on the upper end of the piston I4. The secondary valve 78 and a valve spring 80 having a corrugated cross section are integrally molded from plastic, and furthermore, a positioning plate 82 is integrally molded at the upper end of the valve spring, and a fall prevention rod 84 extending upward from the secondary valve is integrally molded. There is. By integrally molding the secondary valve 78 and the valve spring 80 in this way, there are advantages that the number of parts can be reduced and assembly can be made easier. Since the valve spring 80 is made of glass, there is little risk of corrosion due to liquid that should flow out.

The assembly and operation of the disk sensor 10 configured as described above will be described below. First, regarding the assembly, it is necessary to apply a rounded so-called parnon lock to prevent the helad 46 from being suppressed before use. The assembly between the head 4g, parnon ring 66 and middle guy f240 is done as follows, for example.First, from above,
Attach the virgin ring gif cag 24 so that the lock #72 is locked to the lock protrusion 36 of the cap. When the locking groove rx is locked to the locking protrusion 3σ, the locking protrusion 68 of the ring is aligned with the triangular notch 35 of the lock #110 of the cap. Then, the head 46 is attached to the cap 24 from above. head 46
Rounding the installation, shape the head so that the triangular shape @Stt of the head does not line up with the locking protrusion of the parnon ring! defeat. Thereafter, by rotating the head, the triangular part 51 is fixed in the triangular notch 35 of the cap at 4/9, and at the same time, the non-ring locking protrusion 68 is fixed at 1g of the head.

locked inside. In this state, the locking groove 72 of the parnon ring 66 is locked with the locking protrusion 36 of the cap, thereby preventing the parnon ring 66 from rolling. Maku nozzle 4σ is II
Since the locking protrusion j1 of the IσoK parnon ring is locked, it cannot rotate relative to the virgin ring gg4c, and as a result, one rotation of the nozzle relative to the character 7''K is indirectly prevented.IK head 4i When the triangular part 58 of the locking protrusion is locked in the locking notch 35 of the cap, the upward movement of the head is obstructed.In this way, the head 460 is prevented from rotating and rising. is done, and the virgin lock is completed.Then, open the secondary valve 7 from below the head 4gK.
8 and the piston 14 are attached, and the cylinder 12 containing the primary valve 22 and the spring 40 is pushed into the cap 24 from below to complete the die assembly. The head 45, the virgin ring 6
The above assembly method for 6 and character fx4 is an example. □
Alternatively, for example, the triangular portion 58 of the head may be locked with the protrusion 68. Align the notches ssK and press the head 1. ``Using the elasticity of the plastic, forcefully lock the triangular part in the notch 35 and the spatula 1'0fl160 in the locking protrusion 68, respectively.

Prior to starting use, the persynlock is released by pressing as follows. If the lever 74 of the virgin ring is rotated in the direction of the arrow shown in FIG.
It can be removed from the dispenser 10. parnon ring 6
If d is removed, the hect 46 will rotate, and if the head is rotated in the direction of the arrow, the triangular portion 58 of the head will be released from the lock Ir1ss of the cap, and the lock will be released. Here, the head 4 is pressed in the direction in which the piston 14 protrudes, that is, upward, by the biasing force of the spring 40 (7). Move to its elevated position.

The outflow of liquid by the dispenser 10 is performed as follows: the piston together with the head 4c) / l j −A

mm --- Negative pressure is created where the volume increases. The nine primary valve 2z rises against its own weight and separates from the valve seat.

- When the next valve 22 opens, the liquid in the container 2p is sucked up into the variable space 20 and the flow path 19 via the suction pipe z6. Then, against the biasing force of spring 4Q, head 4
When C is pressed, the liquid in the variable space 20 is pressurized. When the pressure of the pressurized liquid overcomes the biasing force of the valve spring 80 of the secondary valve, the secondary valve 18 is separated from the valve seat r6, and the pressurized liquid flows out from the outflow hole 50 via the flow path 411.52. be done. When the pressure of the pressurized fluid decreases due to outflow and becomes smaller than the biasing force of the valve spring 80, the biasing force of the valve spring causes the secondary valve y8Fi to
The outflow is terminated by being pressed against the valve seat 76. When the pressing force on the bale head 4C is removed, the head returns to its raised position by the biasing force of the compression coil spring 40, and at this time the liquid is sucked up again, completing preparations for the next outflow operation.

In addition, in the example, Parnon ring 66Fi cat 7
'2411c, the rotation is prevented and there is no means to prevent rising, but the virgin ring 6
It goes without saying that it would be better to attach c to character f14 so that it cannot rotate or rise.If the virgin ring 66 is made impossible to rotate or rise, the head 4σ will relate to the virgin ring instead of the cap 24. You may stop. For example, the locking protrusion 36 of the cap 24 is made partially spherical, and the locking groove 72 of the virgin ring 66 is made partially spherical.
If et < a groove having a partial shape that is forcibly locked, the virgin ring 56 is attached to the head 24 so that it cannot rotate or rise.

Then, the head 46 is attached to the locking protrusion 68 of the virgin ring 6c.
If the window 6o is forcibly locked, the rotation of the head is prevented without any play because the width of the locking protrusion 68 is slightly smaller than @go and the gap therebetween is small. The rotation of the head 46 can be prevented by the shoulder portion 70 of the nine locking center springs 68 coming into contact with the lower edge of the window 60.

Furthermore, the locking projection 36.68 and the corresponding lock *vstt
For example, in the embodiment, the locking protrusion 36 is formed on the cap 24, the locking 1177 is formed on the virgin ring 6σ, or the locking protrusion 3σ is formed on the virgin ring, and the locking groove is formed on the virgin ring. It goes without saying that 72 may be formed into a cap. The number, circumferential position, shape, etc. of the locking protrusions and locking grooves can be changed as necessary.

The r-ispenser of the present invention can be applied as a sysglayer by disposing a vortex means such as a spinner in contact with the outlet hole KII of the nozzle, and as a sifter by disposing a foaming means in the same way. In this application, the word "dispenser" is considered to be a general concept that includes "sugereya" and "7ohmer".

As described above, the dispenser according to the present invention is formed in a parnon cylinder that is removably disposed between the child play means 7 and the cat head, and includes means for preventing the rotation and rise of the head, and a means for pushing the piston. Nine locking protrusions or locking grooves formed on the outer wall □ of the cap extending in the direction;
The head is equipped with nine locking grooves and nine locking grooves. The childproof means has a locking part formed on the cap, and a locking part formed on the inner wall of the head that rotates at the pushed-in position of the piston. A locking protrusion that locks the piston together with the head in the pushed-in position 11 is provided.

Further, when the head rotation/rise prevention means is moved in the piston 0 pushing direction, the locking protrusion 9 of the head is locked in the locking groove, thereby preventing at least the rotation of the virgin ring relative to the ring 7"K. and a twentieth locking means which locks the locking protrusion of the head in the locking groove by being suppressed in the pushing direction of the piston and prevents at least rotation of the head relative to the cylinder cylinder. The dispenser is configured as described above, and is childproof so that the piston and head can be repeatedly locked in the pushed position regardless of whether before or after the start of use. In some cases, the head rotation/rise prevention means works in conjunction with the child blues means, or the head rotation/rise prevention means alone prevents the head from rotating and rising and secures the lock at the pushed-in position. There is.

Unnecessary and inadvertent suppression of the head is completely prevented regardless of whether before or after the start of use, and accidents caused by liquid leakage are prevented. In addition, since the head is locked in the push-in position before use, the overall length of the dispenser is small, which is advantageous for transporting II packages.

The above-mentioned embodiments are for illustrating the present invention and are not intended to limit the present invention in any way, and the present invention includes all modifications and modified capes within the technical scope of the present invention. Needless to say, it will be done.
