Abstract

An automatic filling up spuit (100) screwed to an entrance (1a) of a cosmetics container (1) for suctioning and discharging liquid stored in the cosmetics container (1) includes: a spuit pipe (10); a cylinder member (20); a piston member (30); a cylindrical push button (50); and a top/bottom-opened cylindrical enclosure (60). The automatic filling up spuit has an advantage of convenient use in that it is capable of automatically filling up liquid contents in a cosmetics container by a certain amount precisely at all times through joining with the cosmetics container without requiring a separate filling up operation.

Claims

1. An automatic filling up spuit configured to be screwed to an entrance of a container for suctioning and discharging liquid stored in the container, the spuit comprising:

a spuit pipe configured to serve as a passage for suction and discharge of the liquid stored in the container;

a cylinder member connected to a top inner circumference of the spuit pipe;

a piston member including

a horizontal member,

a bar-shaped piston extending downward from a center of the horizontal member and inserted within an interior of the cylinder member,

a cylindrical packing on an outer circumference of a bottom part of the bar-shaped piston,

at least one vertical guide extending downward from the horizontal member, and

a circular projection extending upward from the center of the horizontal member;

a cylindrical piston guide member configured to guide a vertical movement of the piston member, the cylindrical piston guide member enclosing an outer circumference of the piston member and including

an opened top,

an opened bottom, and

at least one vertical groove formed on an inner circumference of the cylindrical piston guide member and coupled with the at least one vertical guide of the piston member;

a cylindrical push button including

a top wall,

an opened bottom, and

an insertion projection extending downward from a center of the top wall and enclosing

an outer circumference of the circular projection of the piston member; and

a cylindrical enclosure enclosing an outer circumference of the cylindrical push button and an outer circumference of the piston guide member,

wherein the cylindrical push button is mounted on the cylindrical piston guide member and connected to the piston member via the insertion projection and the circular projection,

wherein, when the piston member rises, the cylinder member is filled with the liquid suctioned from the container via the spuit pipe, and

wherein, when the piston member is descended by pushing the cylindrical push button, the liquid filled in the cylinder member is discharged from the cylinder member.

2. The automatic filling up spuit according to claim 1, wherein the cylinder member includes:

an inner cylinder having a bottom part engaged with the top inner circumference of the spuit pipe;

a horizontal part connected to an outer circumference of a middle part of the inner cylinder;

a cylindrical portion formed on the horizontal part and having an opened bottom;

an inclined groove symmetrically formed on an outer circumference of the cylindrical portion; and

a screw combining portion formed on an inner circumference of the cylindrical portion and configured to be screwed to the entrance of the container.

3. The automatic filling up spuit according to claim 2, wherein

the at least one vertical guide of the piston member includes two vertical guides arranged on opposite sides of the bar-shaped piston,

the at least one vertical groove of the cylindrical piston guide member includes two vertical grooves, and

the piston member further includes a pair of horizontal bars each projecting from a bottom of a corresponding one of the two vertical guides, and received in a corresponding one of the two vertical grooves.
