Description

Airless type cosmetic container with side discharge passage {AIRLESS TYPE COSMETICS VESSEL WITH A SIDE DISCHARGING PASSAGE}

The present invention relates to an airless cosmetic container, in particular, to provide a reduction in manufacturing cost by minimizing the components, as well as to enable the button member and the piston member to move in the same axial direction, so that the single tube is repeatedly pressed by the button member. Accurate dispensing is provided through the side discharge passage guided to one side of the cosmetics introduced into the cylinder chamber of the discharge cylinder, which prevents uneven wear of the elevating member and prolongs the prevention of cosmetic leakage. It relates to an airless type cosmetic container having.

In general, the airless type cosmetic container discharges the cosmetics introduced into the cylinder by the operation of the pumping mechanism configured inside the cap assembled on the upper part of the container member containing the liquid (gel-like) cosmetics, that is, by the lowering of the upper button member. That's the way.

These airless cosmetic containers are largely classified in two ways.

One is to discharge the cosmetics (intake) flows into the inside of the pumping mechanism while the outlet (nozzle) flows by lowering the cap (button member function) having a discharge outlet integrally,

The other is a method of injecting and dispensing cosmetics by pressing the button member operating separately on one side in the cosmetic discharge port is fixed.

The former nozzle (outlet) flow type has a disadvantage in that the outlet (nozzle) cannot be ejected to the correct part of the skin to be applied during the ejection of the gel-like cosmetics by the lifting operation.

The latter nozzle fixed cosmetic container has the advantage of being able to be discharged to the skin to be applied to cosmetics because there is no movement of the nozzle (outlet) through which the gel-like cosmetics are discharged even when the button member is pressed.

The scope of the present invention belongs to the latter nozzle fixed manner.

Japanese Patent Application Laid-Open No. Hei 10-120054 "EJECTION CONTAINER" (hereinafter referred to as source technology 1) is disclosed for such a nozzle fixed type cosmetic container.

Said source technology 1 is a pump means for storing a container made of a deformable material in which the contents are enclosed in a storage chamber of an outer container, installing a spout in the outer container, for transporting fluid into the storage chamber and pressurizing the inner container. It is configured to form a check valve communicating with the inside of the inner container and inducing the contents in the inlet to the outlet, and the usual abolition of the air flow into the inside of the inner container in the outlet.

However, the source technology 1 is to shrink the inner container by the fluid compressed by the pressure of the pump means installed in the outer container and to discharge the contents contained in the storage chamber of the inner container through the spout, so that the inner container must be a material that can be contracted. At the same time, the airtightness between the inner container and the outer container must be maintained, and a check valve for maintaining the compressive force of the fluid by pressurization of the pump means and a check valve for normally eliminating the inflow of air into the inner container, There is a complexity of the structure.

In addition, Japanese Patent Laid-Open No. Hei 10-278956 discloses a "liquid discharge container" (hereinafter referred to as source technology 2).

Said source technology 2 is provided with a pumping pipe in the center of the upper body of the container body and the mounting cylinder fitted to the outer surface of the said container body diameter, and also made the small diameter cylinder and the large diameter cylinder stand up, and protruded the nozzle to the front part of the said large diameter cylinder lower part. The ejector main body, a piston member having the first cylinder and the second cylinder with the upper plate downward and fitted into the small diameter and the large diameter cylinder, the coil spring for pressing the piston member upward, and the upper surface of the large diameter cylinder. It was formed as a preventing member for preventing the escape of the piston member.

Said source technology 2 is a first elastic cylinder which has an inlet valve formed at the lower end of the first cylinder which is brought into contact with and lifted from the inner surface of the small cylinder, and the second barrel which is brought into contact with the inner surface of the large cylinder and the outer surface of the small cylinder. It is a method of sucking and discharging the contents by a second elastic valve having a discharge valve formed at the lower end thereof.

In particular, the pressure of the upper plate is discharged to the nozzle by discharging the inner and outer surfaces of the first and second angle cylinders and the small-diameter cylinder of the upper plate through the zig-zag while the contents are sucked upward through a central pumping pipe. There was a lot of uncomfortable load caused by a lot of effort in hand operation.

In addition, Japanese Patent Laid-Open No. Hei 10-296141 discloses a "pump dispenser" (hereinafter referred to as source technology 3).

Said source technology 3 has an outer cylinder, a nozzle tube fixed to the outer cylinder, a moving cylinder communicating with the nozzle tube and moving in the outer cylinder, and a slit connected to the moving cylinder and penetrating the nozzle tube to form a movable pressure. A fluid is provided, and the fluid sucked into the end of the outer cylinder by press-fitting the movable cylinder is discharged to the nozzle tube.

The source technology 3 has the disadvantage that the wear of the airtight piece protruding from the upper end of the inner tube of the pressurizing body which elevates the inside of the nozzle tube to the airtight state easily occurs, and the leakage of contents into the space with the outer tube and the center of the pressurizing body. The other supporting force to the movement is simply supported by the annular projection protruding inside the upper end of the outer cylinder, so the space of the axial movement is large, so that the eccentric movement occurs easily and the service life is not guaranteed due to the occurrence of uneven wear.

In addition, Korean Utility Model Registration No. 20-311496 "Nozzle Fixed Dispenser Container" (hereinafter referred to as source technology 4) is disclosed.

Said source technology 4 is configured to open and close the check valve in a cylinder by the elevating operation of the pumping stem which the outflow of gel cosmetics couple | bonded with a button, and to discharge it through the nozzle of a discharge head through the central passage of the pumping stem.

The source technology 4 is that the button is eccentrically coupled to the pumping stem, so that the pressing space of the finger is narrow so that a certain pressing force for the pumping operation of the button according to the ejection of the contents is not provided. Lifting operation is provided, and it is difficult to pressurize in the uniform axial direction (pressing in the same axial direction), and the cosmetics are leaked by the uneven wear phenomenon of the pumping stem which is repeatedly lifted and operated, and it acts on the coupling part of the pumping stem and the button. There is a disadvantage in that noise is generated during the pressurization operation of the button due to deformation due to the single load, and the lifting operation of the button is not made smoothly.

In addition, the source technology 4 is the intake of the gel-like cosmetics in the cylinder by the piston rod and the pumping stem is increased by the adoption of the check valve, the outflow passage and pumping through the piston rod by the lowering of the piston rod and the pumping stem As the vertical pressure rises through the center passage of the stem and the discharge is carried out through the nozzle, the load is severe due to the pressurization of the button, and the elastic deformation of the return spring of the check valve that repeatedly contracts and expands while the cosmetic is sucked and filled into the cylinder. There is a disadvantage in that the reliability of the product is lowered due to malfunction of the return rise of the button is not properly.

Further, the source technology 4 has a disadvantage in that the pressing force is large because it is a method of raising and dispensing the cosmetics sucked up to the upper pipe in correspondence with the descending distance of the pumping stem and the piston rod as in the source technologies 1 to 3.

Thus, the applicant thus discharges the cosmetic discharge inside the container through the discharge pipe formed on one side rather than the axial direction of the piston and at the same time the lifting of the button member is provided in the same direction as the axial direction of the piston, Maximizes the lifespan guarantee by blocking the action of eccentric load and preventing the outflow of cosmetics even for long-term use by preventing eccentric wear between lifting members.

As the discharge of cosmetics is provided by the discharge pipe guided to one side, the button member can increase the user's finger contact share by the same axial movement as the piston, so that the smooth pressing action and the elastic return force of the return spring can be achieved even with a small pressure. Patent application No. 10-2008-0102597 has been filed for an airless type cosmetic container that is utilized only for the lifting operation of the button member and provides a uniform operation even for long-term use and prevention of malfunction of the button member due to deformation prevention.

Moreover, a separate cylinder support component supporting the discharge cylinder is required to form the side discharge path, and also provided with a double pipe structure for assembling each other and forming the side discharge path, which has a complex and disadvantage of assembly workability.

Therefore, in the present invention, the applicant's prior application technology is improved to minimize the components and simplify the structure, while discharging cosmetics inside the container through the side discharge passage formed on one side instead of the axial direction of the piston, and raising and lowering the button member at the same time. It is provided in the same way as the axial direction of the block to prevent the eccentric load caused by the operation of the button member to prevent eccentric wear between the elevating member is aimed at maximizing the guarantee of the life without the spillage of cosmetics despite long-term use.

That is, the present invention is the discharge of the cosmetic is provided by the side discharge passage formed on the side of the discharge cap, the button member is configured to make the same axial movement as the piston to increase the user's finger contact occupancy of the small force It is a characteristic purpose to prevent the rising malfunction of the button member due to the deformation prevention is utilized only by the pressing action of the spring and the elastic return force of the spring even when pressurized.

In addition, the present invention is provided with the same axial movement of the elevating operation by the pressure of the button member and the elastic force of the spring to contact the contact portion of the piston outer peripheral surface and the discharge cylinder inner peripheral surface of the elevating member and the guide shaft groove of the piston rod and the outer peripheral surface of the guide shaft of the shaft valve The characteristic purpose is that the partial wear of the part is minimized so that uniform operation is provided even in long-term use to ensure reliability.

The shaft valve is frictionally lowered by the pressurization of the button member so that the outer opening and closing ring of the shaft valve opens the side discharge path of the discharge cylinder, and the inner opening and closing ring is in close contact with the opening and closing seat of the lower inlet of the cylinder chamber. It prevents the cosmetics flowing into the cylinder chamber from flowing out into the container body and discharges the cosmetics inside the cylinder chamber through the discharge passage of the discharge cap via the side discharge passage of the discharge cylinder by the continuous compression lowering of the piston. It is characterized by
