Abstract

Provided is a tube-type cosmetic container which discharges a liquid content in a form of droplet. The tube-type cosmetic container reduces the cost burden in accordance with shortening of the manufacturing time and reducing cost, by allowing a liquid content to be discharged in a form of droplet through a simple content discharging structure that becomes gradually wider from a lower portion to an upper portion thereof.

First claim

The invention claimed is:

1. A tube-type cosmetic container for discharging liquid contents in a form of droplets, the container comprising:
a tube body storing contents;
a tube neck coupled to an upper portion of the tube body to support the tube body and having an outlet hole such that contents stored in the tube body are discharged therethrough;
a discharge control part coupled to an inner side of the tube neck and comprising a discharge control tube which gradually becomes wider from a lower portion to an upper portion of the discharge control tube so as to control an amount of discharge when contents discharged through the outlet hole move upward;
a content discharging tube directly coupled to an upper portion of the tube neck, wherein the content discharge tube presses the discharge control part downwards to fix the discharge control part to an inner side of the tube neck, and having a discharge hole formed on an upper end of the content discharging tube; and
an over cap coupled to the tube neck while covering an outer side of the tube neck, and comprising a closing rod so as to close the discharge hole of the content discharging tube,
wherein the content discharging tube is configured with a lower portion and an upper portion, which has a narrower diameter than the lower portion and extends from the lower portion to the discharge hole, such that when the tube body is pressurized, contents filled in the inside of the content discharging tube through the discharge control tube, while being discharged through the discharge hole, pass through the upper portion of the content discharging tube, and are discharged out of the container in a form of droplets,
wherein the lower portion of the content discharging tube is disposed radially inwardly of the inner side of the tube neck between the tube neck and the discharge control part,
wherein the discharge control part is entirely disposed radially inwardly of the tube neck, and
wherein the over cap directly engages the tube neck.

2. The tube-type cosmetic container of claim 1 , wherein the discharge control part comprises a seating stopper surrounding an outer circumferential surface of the discharge control part such that a lower portion of the content discharging tube is seated on the seating stopper, and the content discharging tube comprises a seating protrusion formed at the lower portion of the content discharging tube and seated on the seating stopper.

3. The tube-type cosmetic container of claim 1 , wherein the content discharging tube is directly coupled to the upper portion of the tube neck.

4. A tube-type cosmetic container for discharging liquid contents in a form of droplets, the container comprising:
a tube body storing contents;
a tube neck coupled to an upper portion of the tube body to support the tube body and comprising a discharge control tube which gradually becomes wider from a lower portion toward an upper portion of the discharge control tube so as to control an amount of discharge of content stored in the tube body when contents are discharged by pressurization of the tube body;
a content discharging tube coupled to an upper portion of the tube neck and having a discharge hole formed on an upper end of the content discharging tube so as to discharge contents moving upward through the discharge control tube out of the content discharging tube; and
an over cap coupled to the tube neck while covering an outer side of the tube neck, and comprising a closing rod so as to close the discharge hole of the content discharging tube,
wherein the content discharging tube has a lower portion and an upper portion, which has a narrower diameter than the lower portion and extends from the lower portion to the discharge hole, such that when the tube body is pressurized, contents filled in the inside of the content discharging tube through the discharge control tube, while being discharged through the discharge hole, pass through the upper portion of the content discharging tube formed with a narrow diameter, and are discharged out of the container in a form of droplets,
wherein the discharge control tube is structurally separate from the content discharging tube,
wherein the discharge control tube is integrally formed with the tube neck and extends into an interior of the tube body, and
wherein the over cap directly engages the tube neck.

5. The tube-type cosmetic container of claim 4 , wherein the discharge control tube is an integral part of the tube neck.
