Description

Multi-purpose solution dispenser {MULTIPURPOSE SOLUTION EXTRUDER}

The present invention relates to a top-down solution discharge device for applying a pressure to the container to discharge the solution in the container.

Conventional top-down solution discharging device was a top-down container stopper (utility model registration number: 1991-0006885).

However, the conventional top-down container stopper has a merit that some of the solution remaining in the inlet and the outlet chamber is sucked into the inlet chamber when the pressure applied to the container is removed, but the solution remaining in the outlet portion is introduced into the inlet chamber. If air is drawn in through the outlet, the continuity of the solution remaining in the inlet and outlet chambers is broken (especially this is noticeable in the outlet compartment), so that air is drawn through the inlet and still inlet and outlet There was a disadvantage that the solution remained in the room.

In addition, the conventional top-down container stopper has a disadvantage in that the solution remaining in the inlet chamber adheres to the tangier spring inside the inlet chamber when the viscosity of the solution is large, resulting in difficulty in collecting the remaining solution in the inlet chamber at the end of the life of the top-down container cap. there was.

In addition, the conventional top-down container stopper takes a portion of the solution remaining in the inlet and outlet chamber into the inlet hole when the pressure in the container is restored to its original state, and thus, when the viscosity of the solution is large, it takes a considerable time for the pressure in the container to be restored to its original state. There was a disadvantage.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide an empty space between the outer end of the discharge stopper and the distal end of the discharge stop when the discharge stopper is closed. It is to provide a top-down solution discharge device that prevents contact with air.

In addition, the present invention also provides a top-down solution discharge device that can easily collect the solution remaining in the solution discharge device at the end of the life of the solution discharge device by preventing the solution from contacting the elements such as the spring.

In addition, the present invention also provides a top-down solution discharging device for reducing the time to restore the pressure in the container to the original air only by introducing the air into the solution discharging device in the step of restoring the pressure in the container.

In addition, the present invention also provides a top-down solution discharge device having a discharge control device for controlling the discharge of the solution.

Referring to Figure 1, the solution discharger according to the present invention has a connection portion 12 connected to the lower portion of the container 10 and a discharge port 14 through which the solution is discharged. The outlet 14 is preferably conical with a cross-sectional area decreasing toward the outside from which the solution is discharged, but may be cylindrical or otherwise shaped.

1 and 3, the solution discharger according to the present invention has a body 20 and a cylinder 30. The outlet 14 is connected to the body 20, the body 20 is formed a space therein. On the other hand, the cylinder 30 is formed inside the body 20 is connected to the body 20 through the side portion of the cylinder 30. One end of the cylinder 30 is open to the interior of the body 20, the other end has a diaphragm support hole 40 to communicate with the interior of the body 20.

Referring to FIG. 1, a piston 50 is inserted into a cylinder 30. 1 and 5, the piston 50 is preferably such that the outer surface is made of a piston seal (50a) in close contact with the cylinder (30). In addition, the piston rod 52 is connected to one end of the piston 50, the discharge plug 60 is connected to the other end. The cross-sectional area of the piston rod 52 is preferably smaller than the cross-sectional area of the piston 50. 1 and 6, the discharge plug 60 is formed to be in close contact with the discharge port 14, when the discharge plug 60 is blocking the discharge port 14, the outer end of the discharge plug 60 is the discharge port ( It is advisable to coincide with the distal end of 14) or to project out of the outlet. Therefore, when the discharge port 14 is conical, the discharge plug 60 has a contact portion with the discharge port 14 to be conical, and the diameter of the minimum end surface of the cone surface of the discharge plug 60 is the inner diameter of the distal end of the discharge port 14. It is preferred to be less than or equal to. In addition, when the discharge plug 60 presses the discharge port 14 when the discharge plug 60 is blocking the discharge port 14, the pressure is applied by the pressure to the piston 50 rather than the discharge plug 60 in the piston 50 moving direction. This should work great. Therefore, when the contact portion with the outlet 14 of the outlet 14 and the outlet plug 60 is conical, the cross-sectional area of the largest diameter A-A in the conical surface of the outlet plug 60 should be smaller than the cross-sectional area of the piston.

1 and 3, the piston 50 has a cylinder middle wall 70 for dividing the inside of the cylinder 30 between one end and the other end. The cylinder intermediate wall 70 is formed with a piston rod support hole 72 into which the piston rod 52 is inserted and an inner vent hole 74 through which one end and the other end of the cylinder 30 pass.

2 and 4, an outer vent hole 76 is formed through the side surfaces of the body 20 and the cylinder 30 to communicate with the atmosphere, and the outer vent hole 76 is formed between the cylinder intermediate wall 70 and the outer vent hole 76. It is formed between one end of the cylinder (30). In the case where the outer vent hole 76 is formed between the cylinder middle wall 70 and the other end of the cylinder 30, the inner vent hole 74 is not necessarily formed.

Referring to Figure 1, the piston rod 52 is fitted with an elastic member 80, the elastic member 80 is installed between the piston 50 and the cylinder middle wall (70). The elastic force of the elastic member 80 is such that the discharge plug 60 is sufficient to block the discharge port 14 when no additional force is applied to the solution discharger.

1 and 3, a diaphragm support rod 90 is inserted into the diaphragm support hole 40. The diaphragm support rod 90 is formed to be loosely fitted into the diaphragm support hole 40. On the other hand, the diaphragm 92 is connected to one end of the diaphragm support rod 90 is installed outside the cylinder (30). The diaphragm 92 is formed to seal the diaphragm support hole 40 upon contact with the other end of the cylinder 30. In addition, referring to Figures 1 and 7, the other end of the diaphragm support rod 90 is provided with a departure preventing member 94 is installed so that the diaphragm support rod 90 is not separated from the diaphragm support hole 40. desirable.

1 and 8a, the solution discharger according to the present invention includes a discharge control device 100, the discharge control device 100 is a hole formed in the side of the cylinder 30 through the body 20 It is installed through.

Referring to Figure 1, Figure 8a, the discharge control device 100 has a discharge switch 102 in close contact with the body 20 is installed on the outside of the body (20). Discharge switch 102 is preferably to have a rotary projection (102a) on the side or top to facilitate rotation of the discharge switch (102). Referring to FIG. 2, the discharge switch 102 and the body 20 should be in close contact with each other, so that when the bottom of the discharge switch 102 is made flat, a seating part in which the discharge switch 102 of the body 20 rests ( The top of 22) should also be flat.

1 and 2, a discharge control device installation hole 200 is formed to pass through the seating part 22 to the side surface of the cylinder 30. Referring again to FIGS. 1 and 8A, the bottom of the discharge switch 102 is connected to one end of the switch supporting rod 104 inserted into the discharge control device installation hole 200. In addition, the other end of the switch supporting rod 104 is connected to the discharge control cam 106 to limit the moving distance of the piston 50 by rotating as the discharge switch 102 rotates in contact with the piston 50. At this time, the other end portion of the switch support bar 104 to which the discharge control cam 106 is connected should not be introduced into the cylinder 30 so as not to interfere with the movement of the piston 50.

1 and 2, the stop ball 102b may protrude from the bottom of the discharge control device 100. At this time, it is preferable that a stop ball stop groove 22a into which the stop ball 102b can be inserted is formed on the seating part 22. In addition, referring to FIG. 8B, an emission control indicator 102c may be formed on the upper portion of the emission control device 100 and the upper surface of the discharge port to know the position of the emission control cam 106. The discharge control cam 106 is in the state of "Closed" in FIG. 8B when the "C" display portion of the discharge switch 102 coincides with the "H" display portion, and FIG. 8B when the "1" display portion coincides with the "H" display portion. Is in the state of "1st", and the "2" display portion is in the state of "2nd" in FIG. 8B, and the "O" display portion is in the state of "H" display portion, the " 3rd " full open) ".

Hereinafter, the operation of one embodiment having the above-described configuration will be described in detail.

Referring to FIG. 1, when the container 10 is pressed, the internal pressure of the container 10 increases. On the other hand, the cross-sectional area of the piston 50 perpendicular to the direction of movement of the piston 50 is S _P , the cross-sectional area of the largest diameter AA of the conical surface of the discharge plug 60 is S _C , and the solution is discharged from the piston 50. When the pressure acting on the stopper 60 is P (ignoring the pressure difference due to the difference in the height of the solution), the force acting on the piston 50 is P * S _P and the force acting on the discharge stopper 60 is P * S _C, but the cross-sectional area S _P of the piston 50 is larger than the cross-sectional area S _C of the largest diameter AA of the conical surface of the discharge stopper 60, so that the discharge stopper 60 blocks the outlet 14. If present, the force exerted on the piston 50 by the solution is greater than the force exerted on the outlet plug 60 by the solution. Therefore, when the internal pressure of the container 10 is large enough to overcome the force by the elastic member 80 (including the force by the atmospheric pressure inside the cylinder 30), the piston 50 and the discharge plug ( 60 moves in the opposite direction of the outlet 14 so that the outlet plug 60 opens the outlet 14.

In addition, when the outlet 14 is opened and the solution begins to be discharged through the outlet 14, the solution contacts the conical surface and the conical surface minimum diameter end of the outlet stopper 60, thereby applying pressure to the outlet stopper 60. 14) The pushing force to the opposite side is instantaneously increased so that the outlet 14 opens smoothly.

On the other hand, when the solution is discharged through the discharge port 14, the internal pressure of the container 10 is lowered, and the force for moving the piston 50 and the discharge plug 60 is restored by the elastic member 80 at some point (cylinder ( 30) includes the force due to the internal atmospheric pressure.) If the solution flows out a little more, the restoring force by the elastic member 80 (including the force due to the atmospheric pressure inside the cylinder 30). Discharge plug 60 is to block the outlet (14). Therefore, the discharge of the solution is stopped.

In addition, if the pressure applied to the container 10 is removed even while the solution is being discharged, the pressure acting on the solution is lowered, and the restoring force by the elastic member 80 (including the force by the atmospheric pressure inside the cylinder 30). By the discharge plug 60 is to block the outlet (14). Therefore, the discharge of the solution is stopped.

On the other hand, if the pressure applied to the container 10 is removed, the container 10 is restored to its original state by the elastic force of the container, and thus suction force is generated in the container 10, so that the diaphragm 92 moves inside the body 20. The diaphragm support hole 40 shown in Figs. 1 and 3 is opened. At this time, the release preventing portion 94 prevents the diaphragm support rod 94 from being separated from the diaphragm support hole 40. When the diaphragm support hole 40 is opened, air flows in at a high speed through the diaphragm support hole 40. At this time, when the amount of air introduced corresponds to the volume of the discharged solution, the suction force in the container 10 is dissipated so that the diaphragm 92 closes the diaphragm support hole 40 again.

On the other hand, when the air flows through the diaphragm support hole 40, the interior of the cylinder 30, the inner vent hole 74 shown in Figs. 1 and 3 and the outer vent hole 76 shown in Figs. Air is replenished from outside through.

Meanwhile, the piston rod support hole 72 shown in FIGS. 1 and 3 allows the piston 50 to move smoothly inside the cylinder 30 and at the same time supports one end of the elastic member 80 to support the elastic member ( 80) allow elastic force to be applied.

On the other hand, since the diameter of the minimum cross-section of the conical surface of the discharge plug 60 is equal to or smaller than the inner diameter of the distal end of the discharge port 14, when the discharge plug 60 is opened and closed, the outer end of the discharge plug 60 is discharged. It coincides with the distal end of 14 or protrudes out of the outlet so that no solution remains between the outer end of the outlet stopper 60 and the outlet 14.

Hereinafter, the operation of the emission control device 100 will be described with reference to FIG. 8B.

When the " C " display portion of the discharge switch 102 coincides with the " H " display portion, as shown in " Closed " of FIG. 8B, the piston 50 cannot move (and therefore the solution cannot be discharged), " 1 " If the "display" coincides with the "H" display, the piston 50 can move to the extent shown in "1st" of Fig. 8B, and if the "2" display coincides with the "H" display, it is shown in "2nd" of Fig. 8B. Piston 50 can be moved to a degree, and when the "O" display portion coincides with the "H" display portion, the piston 50 can move to the extent shown in "3rd (full open)" of FIG. 8B. That is, the maximum amount of discharge of the solution can be adjusted by rotating the discharge switch 102.

As mentioned above, although this invention was demonstrated to the said Example, this invention is not limited to this.

For example, in another embodiment, the flow control cam 106 does not have to have the shape of the above embodiment, but is sufficient if it is made of a protrusion of a certain shape such as a cylindrical or square cylinder.

In addition, in the case of the above embodiment, but to include a discharge control device 100, another embodiment may be not to include a discharge control device (100). At this time, the discharge control device installation hole 200 is not formed.

On the other hand, in the above embodiment, the outer vent hole 76 is formed between the cylinder middle wall 70 and one end of the cylinder 30, but in another embodiment the cylinder middle wall 70 and the cylinder 30 It may be formed between the other end of the). At this time, the inner vent hole 74 does not need to be formed.

In addition, in the case of the above embodiment, but having a cylinder middle wall 70, another embodiment may be not having a cylinder middle wall (70). At this time, one end of the elastic member is connected to the inside of the cylinder 30 and the other end is preferably connected to the piston rod 52 or the piston 50.

In addition, in the case of the above embodiment, but having a piston rod 52, in the case of another embodiment may be not having a piston rod (52). At this time, one end of the elastic member is connected to the inside of the cylinder 30 and the other end is preferably connected to the piston 50, the cylinder intermediate wall 70 does not need to be installed.

In addition, in the case of the above embodiment, but having a departure prevention 94, in another embodiment of the diaphragm support rod 90, if there is no fear of falling out of the diaphragm support hole 40, It can be done without. At this time, the volume inside the cylinder 30 is large, and the length of the diaphragm support rod 90 is preferably long.

In addition, in the present invention, the connecting portion 12 is formed integrally with the container 10 and connected, or when manufactured and connected independently of the container 10, the container 10 and the bolt nut as shown in FIG. It is desirable to allow fastening and also to allow the packing 302 to be inserted.

In addition, in the present invention, it is preferable that the discharge amount switch 102 and the switch supporting rod 104 are connected through the switch fixing screw 304.

According to the present invention, when the discharge plug is closed, the empty space is not formed between the outer end of the discharge plug and the distal end of the discharge port. When the pressure in the container is removed, the solution remains in the discharge port and contacts the air in the atmosphere. The disadvantage is solved.

In addition, the present invention has the advantage that the solution is not in contact with the elements such as the spring, so that the solution remaining in the solution discharge device at the end of the life of the solution discharge device can be easily collected.

In addition, the present invention has the advantage that it is possible to continuously operate the solution discharging device by reducing the time that the pressure in the container is restored to the original pressure only by introducing the air into the solution discharging device in the step of restoring the pressure in the container.

In addition, the present invention has the advantage of controlling the maximum amount of solution discharged in one operation by having a discharge control device, and the advantage of preventing the discharge of the solution by malfunction by leaving the discharge control device in the "closed" state during storage There is this.
