Airles Cosmetic Vessel {AIRLESS COSMETIC VESSEL}

The present invention relates to an airless cosmetic container, and more particularly, to an airless cosmetic container which keeps the airtightness between the piston rod of the pump body and the upper and lower lids, and secures a rising escape space of the piston, .

As disclosed in Korean Patent Application No. 2015-0065802, cosmetics generally contain a large amount of volatile components such as moisture and alcohol. If the cosmetics container is not completely sealed due to moisture or volatile components, moisture is evaporated and volatile components are volatilized The amount of cosmetics is reduced, and the blending ratio between cosmetic components changes due to evaporation of water or volatilization of volatile components, resulting in deterioration of performance of cosmetics.

Furthermore, since cosmetics are evaporated and volatile components are volatilized, they become dry and lose the original function of cosmetics. Therefore, it is very important to always keep cosmetics in their original composition.

In order to prevent this, conventionally, a conventional cosmetic container is provided with a sealing lid which keeps the airtightness for evaporation of water and volatilization of volatile components. In the conventional cosmetic container, a cosmetic container, Packing was installed to ensure airtightness.

A mirror 101 is attached to the lower surface of the upper case 100 and a tension rubber 102 is inserted between the outer wall of the lower case 10 and the inner wall of the upper case 100 to seal them.

When the button 90 is pushed in the horizontal direction with respect to the lower container 10, the button spring 91 is compressed so that the latching protrusion 92 of the upper end of the button spring 90 is engaged with the latching groove 103 of the upper case 100 So that the upper case 100 can be opened.

The pump body 70 is a cylindrical member inserted and coupled to the bottom of the lower projection groove 31 of the container cover 30. The pump body 70 includes a lower cylinder having an upper portion opened and a cosmetic contents inlet hole 71a formed at the lower center, The upper cylinder 71 is provided with an outer circumferential projection 72a which is placed on the upper end of the lower cylinder 71 at its outer periphery. The lower cylinder 71 is connected to the inner circumference of the lower cylinder 71, A cylindrical suction valve 73 coupled to the inner peripheral lower end of the upper cylinder 73 and a tee 74 coupled to the cylindrical groove 74c of the coupling column 62 of the lower lid 60, And a piston rod 75 coupled to the center hole 74a of the piston support 74. The piston support body 74 has a center hole 74a communicating with the center of the piston support body 74, , The inner periphery thereof is fitted to the lower outer periphery of the piston rod (75), and the lower end of the piston rod (75) A cylindrical valve 76 which is supported at its lower end by a planar projection 75a and whose upper edge is in contact with the inner peripheral edge of the upper cylinder 72 and moves up and down with the piston rod 75 moving up and down, And a pump spring 77 which is supported by the outer circumferential projection 72a of the upper cylinder 72 and whose upper end is supported at the lower surface of the upper surface of the piston support body 74.

An inner hole 75b is formed in the upper center of the piston rod 75 and a communication hole 75c communicating with the inner hole 75b is radially formed on the upper side of the lower horizontal protrusion 75a Respectively.

A locking protrusion 74b formed on the inner peripheral edge of the center hole 74a of the piston support body 74 and a locking protrusion 75d formed on the outer peripheral edge of the piston rod 75 are engaged with each other.

That is, when the piston rod 75 is inserted into the center hole 74a from the lower portion of the piston support body 74, the engaging protrusion 75d is engaged with the engaging protrusion 74b so as not to fall downward.

The inner diameter of the discharge hole 61 is smaller than the inner diameter of the tightening cylinder 62 of the lower lid 60. When the piston support body 74 and the lower lid 60 are engaged with each other, The upper surface of the center hole 74a of the support body 74 closely contacts or overlaps with the lower surface of the discharge hole 61 in the clamping cylinder 62 of the lower lid 60 to strengthen the clamping force.

As the fastening force is strengthened, external air does not flow into the upper cylinder 72 even if the air flows into the plurality of holes 51 of the upper lid 50. [

5A and 5B, the outer periphery of the vertical recess 23 on the outer side of the two vertical recesses 23 of the container 20 is formed with a rigid So that the upper end of the exhaust piston 80 rising at the inner periphery of the inner container 20 is inserted into the outer periphery of the inner container 20 and the inner periphery of the container cover 30 A gap, that is, a space for evacuation is formed between the lower outer periphery.

By inserting the upper end of the exhaust piston 80 into the evacuation space, the contents of the cosmetic product can be exhausted without waste.

Six holes 51 of the disk-shaped upper lid 50 are formed, and the elongated holes are inclined at an angle of 60 ° with respect to each other (FIG. 6).

Reference numeral 24 denotes an air inflow hole formed at the lower end of the content container 20 and through which air flows in from the outside so that the consumable piston 80 rises as the cosmetic content in the content container 20 is exhausted.

Next, operations and effects of the present invention configured as described above will be described.
