Description

Hand-Operated Dual Spray Device

The present invention relates to a manual dual injector, and more particularly, a pair of containers, each of which is equipped with a manual injection pump, a case body in which the containers are built together, and a case body in the state in which the containers are fastened. Fixed shoulder coupled to the open top of the, is mounted on the top of the manual injection pump for vertical movement for pumping and the flow path for discharging each liquid contents from the manual injection pump, so long as it is in communication with the flow path The present invention relates to an actuator having a nozzle in which a pair of nozzles are formed, and a structure including a shoulder cap coupled to a fixing shoulder for guiding vertical movement of the actuator.

In general, the manual pump is classified into a pump of the discharge method such as shampoo, cosmetics, etc. and a pump of the spray method such as perfume and mosquito repellent.

In particular, small hand pumps are widely used in cosmetic containers for dispensing a certain amount of liquid or emulsion contents due to its convenience. In this case, the manual pump is widely used due to the features that can be easily discharged by a certain amount while storing the contents in the container, and related technologies have been continuously developed.

In the main configuration of the conventional manual pump, the housing constituting the external appearance of the pump, the closure used to mount the housing to the container, the stem communicating with the discharge port of the cap and moving up and down along the housing, the vertical movement of the stem A guide shaft connecting the stem to the cap, a piston mounted vertically along the inner wall of the housing while mounted on the stem, a spring mounted below the inner surface of the housing, and a ball opening and closing the inlet at the bottom of the housing; have.

However, these conventional hand pumps have some problems.

First, a compression spring providing restoring force to the pumping system is located inside the housing on the inlet path of the contents, acting as a flow resistance factor. Therefore, a high elastic spring is required or a large inner space of the housing is required, which presents a problem of rigid pumping and large pump size. In addition, there is a problem that makes it difficult to pump the content having a high viscosity.

Secondly, since the compression spring is in contact with the contents on the flow path of the contents, there is a possibility of the compression spring being deteriorated, and when it is changed, it causes contamination of the contents. Third, the opening and closing ball of the lower inlet of the housing acts to open and close the inlet by the pressure change of the inner space of the housing and the action of gravity, so that it is difficult to quickly respond to the pumping operation and also to provide a high sealing force. Therefore, some contents may leak to the container during the pumping operation, and the pumping force may be low due to the inability to perform a quick opening and closing operation.

Various structures have been developed to solve this problem, but few hand pumps provide satisfactory results.

In addition, in recent years, such a container, such as cosmetics, there is a high demand for a simple and easy to use container, for example, a manual double spray pump capable of simultaneously discharging two different types of contents.

The present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

That is, the purpose of the present invention is to use a structure in which two pumps are built in one case, it is possible to discharge different contents at the same time, it is convenient to use, easy to assemble and less risk of failure It is to provide a manual dual injection device.

Manual dual injector according to the present invention for achieving this object is a manual double injector for simultaneously discharging different contents by one pumping,

A pair of containers each having different liquid contents embedded therein, each having a manual injection pump for sucking and discharging the liquid contents to the outside;

A case body in which the containers are embedded together;

A fixing shoulder coupled to the open top of the case body in a state in which the containers are fastened;

It is mounted on top of the manual injection pumps for vertical movement for pumping, and a flow path for discharging each liquid content from the manual injection pumps is formed, and a pair of nozzles communicating with the flow path is one. An actuator formed together on the side; And

A shoulder cap coupled to the fixing shoulder to guide the vertical movement of the actuator;

It is configured to include.

That is, the manual dual injection device of the present invention has a structure in which a pair of manual injection pumps are mounted in one case, and simultaneously discharges different contents embedded in the respective containers by vertical movement of the actuator to the outside. can do. In addition, compared to a conventional manual injection pump in which one pump and a container in which only one type of contents are contained in one case is stored, manufacturing cost can be reduced and portability can be improved.

As one preferred embodiment, the manual injection pump,

(a) a housing constituting the exterior of the pump;

(b) a closure fastened to the upper outer surface of the housing via a housing cap and mounting the housing to a container containing the contents;

(c) a stem including a horizontal passage communicating with the inner space of the housing and a vertical passage communicating with the horizontal passage, the stem being connected to a lower end of the button and vertically moving;

(d) a shaft configured to move up and down along an inner surface of the housing cap in a state of being fastened to an outer surface of the stem;

(e) a housing cap for guiding the up and down movement of the shaft, connecting the housing to the closure, and sealing the internal space of the housing from the outside;

(f) a piston for opening and closing the horizontal passage of the stem in a state mounted to the lower part of the stem and vertically moving along the inner wall of the housing;

(g) a compression spring that provides restoring force to the shaft upon pumping and is located between the side cap and the housing cap formed on the top side of the shaft; And

(h) an opening and closing member positioned at a lower end of the inner space of the housing and opening and closing the lower inlet of the housing during pumping;

It may be configured to include.

When the manual injection pump pressurizes the actuator to pump the contents, the compression spring is compressed, and in the process, the contents of the inner space of the housing are discharged through the horizontal passage and the vertical passage of the stem to the discharge port of the actuator, and vice versa. When the force applied to the rotor is removed, the shaft is lifted by the restoring force of the compression spring, and the contents in the container flow into the inner space of the housing.

Since the compression spring is located between the lateral protrusion of the shaft and the housing cap and not on the flow path of the contents, the compression spring does not act as a factor to inhibit the flow of the contents while providing a restoring force for the pumping operation, and the contents are contaminated by the compression springs. Can be prevented.

In addition, the compression spring structure as described above simplifies the assembly work of the pump, facilitates the modularization of parts, and even when the actuator is removed from the shaft during use, the compression spring can be kept mounted on the pump body. .

In some cases, to further secure the shaft and stem, the upper end of the stem is anchored and fine stems are formed on the corresponding inner surfaces of the shaft, thereby inserting the stem from below the cylindrical structure of the shaft and By tightening can facilitate the mutual coupling.

On the other hand, as described above, when the actuator is pressurized, the contents of the container are discharged to the discharge port of the actuator through the vertical passage of the stem, and when the force applied to the actuator is removed, the restoring force of the spring is transmitted to the shaft and the contents of the container are introduced into the housing. do. At this time, a vacuum space is generated in the container by the volume of the contents discharged through the pump.

Therefore, in order to fill the vacuum space in the container, a piston ('pneumatic piston') that moves upwards by pneumatic pressure (vacuum) may be mounted inside the container whenever the liquid contents are discharged. have.

For example, a pneumatic piston having a diameter that matches the inner diameter of the vessel is installed at the bottom of the vessel, so that the action of the atmospheric pressure applied to the vacuum and the lower portion formed at the top of the high pressure piston while the pneumatic piston is in close contact with the inner wall of the vessel. It can be configured to move to the upper portion by the container. This structure eliminates the problem that the contents remain in the space inside the housing without being pumped.

In addition, when the manual pump is not used for a long time, the contents of the nozzle portion may be solidified and the nozzle may be clogged, or the actuator may be pressurized by an external force such as a drop, and the contents may be spontaneously injected.

Thus, in order to prevent such a phenomenon, it may further include a cover cap detachably coupled to the shoulder cap while wrapping the actuator. That is, the cover cap having a predetermined strength in such a structure can seal the actuator from the outside to prevent the contents of the nozzle portion from solidifying or pressurized by the actuator by itself.

In another preferred example, a partition wall is formed in the case body to form an accommodating part for mounting the containers, and fastening protrusions for fixing the container may be formed at a lower end of the accommodating part.

The partition wall improves the structural stability of the manual dual injector against the vibration and shock applied from the outside, and the fastening protrusions formed on the bottom of the receiving portion to prevent the container from being released from the fixed position by fixing the bottom of the container.

In some cases, the actuator may be a structure in which the portions coupled to the manual injection pump are separated from each other so that each of the manual injection pumps can be operated independently.

The manual injection pump of this structure may select and inject only one type from the two types of contents contained in the container, or may simultaneously discharge or spray the two types of contents by simultaneously pressing the separated actuators. .

The opening and closing member is preferably a hollow member having an open top, with radial projections facing outwards, so as to move quickly and correspondingly according to the vertical movement of the stem, and to provide a high sealing force. The lower end of the stem may be a structure in which a vertical extension is formed in close contact with the hollow inner surface of the opening and closing member.

The material of each component constituting the present invention is not particularly limited, and polyethylene, polyoxymethylene, such as polypropylene, high density polyethylene (HDPE), linear low density polyethylene (LLDPE), etc. in consideration of ease of molding and price, etc. Synthetic resins such as (POM) may be preferably used. Compression springs are generally made of stainless steel, and in some cases, may be made of a plastic material with good elasticity.

FIG. 10 is a vertical cross-sectional view of the manual injection pump constituting the manual dual injection device of FIG. 2. FIG. 11 and FIG. 12 show a downward pressure applied to the actuator (FIG. 1: 600) (hereinafter, " A pump 300 in a state in which the applied pressure has been removed (hereinafter referred to as "relaxation mode") is schematically shown.

First, referring to FIG. 10, the manual injection pump 300 includes a housing 310, a housing cap 320, a compression spring 330, a shaft 340, a stem 350, a piston 360, and an opening / closing member 380. ) And the like. Specifically, in the substantially cylindrical housing 310 having a multi-stage diameter, a housing cap 320 is connected to an upper end thereof, and an upper end of the container 200 is coupled to a side thereof to seal the container 200. The housing cap 320 seals the housing internal space S from the outside and guides the vertical movement of the shaft 340. Since the compression spring 330 is mounted between the lateral protrusion 342 formed at the upper end of the shaft 340 and the housing cap 320, even when the actuator (Fig. 1: 600) is separated from the shaft 340, The compression spring 330 may be stably fixed to the body of the pump 300.

The stem 350 coupled to the inside of the shaft 340 having a cylindrical shape as a whole has a horizontal passage 352 through which the contents of the housing internal space S flow, and a vertical passage 354 perpendicularly connected thereto. ), And the bottommost vertical extension 356. The horizontal passage 352 is opened and closed by a piston 360 moving up and down while being in close contact with the outer surface of the stem 350 and the inner surface of the housing 310. The housing internal space S is opened and closed by the operation of the opening and closing member 380 located directly above the inlet 370.

Referring to FIG. 11, the stem 350 is simultaneously lowered by the lowering of the shaft 340 in the pressing mode of pressing a button, and the compression is located between the lateral protrusion 342 of the shaft 340 and the housing cap 320. Spring 330 is compressed. Immediately after the stem 350 begins to descend, the vertical extension 356 lowers the opening and closing member 380 to immediately close the inlet 370. Therefore, the closing of the inlet 370 by the opening and closing member 380 is made to respond quickly to the pumping operation.

On the other hand, since the frictional force of the outer edge 362 of the piston 360 to the inner surface of the housing 310 is greater than the frictional force of the inner edge 364 to the outer surface of the stem 350, the lower end of the shaft 340. The piston 360 does not move until the upper end of the piston 360 outer periphery 362 is reached. Accordingly, the horizontal passage 352 is opened, and the contents pressurized in the housing internal space S flows into the horizontal passage 352 and rises along the vertical passage 354.

12, the shaft 340 and the stem 350 are simultaneously raised by the restoring force of the compression spring 330 in the relaxation mode, and the outer edge portion 362 and the inner edge portion of the piston 360 as described above. Due to the dualized frictional force of 364, the piston 360 does not move until the inner edge 364 contacts the bottom protruding portion 358 of the stem 350.

Therefore, the stem 350 is raised in a state where the horizontal passage 352 is closed, and a pressure drop in the housing internal space S occurs. This pressure drop is solved by introducing the contents into the housing internal space S while the opening and closing member 380 is opened.

Although described above with reference to the drawings according to an embodiment of the present invention, those skilled in the art to which the present invention belongs will be able to perform a variety of applications and modifications within the scope of the present invention based on the above contents.

As described above, since the manual dual injection device according to the present invention is equipped with a pair of manual injection pumps in one case, two types of contents can be used simultaneously in one product, and the user's convenience and portability Can improve the sex.

In addition, since the compression spring is provided outside the housing, it is possible to reduce the flow resistance of the contents and to prevent contamination of the contents by the springs.

Furthermore, instead of the conventional opening and closing ball, the special opening and closing member and the corresponding internal structure of the housing allow for a high sealing force and pumping force due to the quick operation and excellent sealing performance according to the vertical movement of the pumping system. It can be effective.
