Rolling ball style cosmetic container structure

Abstract

A rolling ball style cosmetic container structure includes a tube, an axle sleeve, a hollow piston rod, a resilient member and an exterior cap. The axle sleeve includes a holding space, an inner flange, an outer flange, a resistant holding surface and a material discharge hole. The hollow piston rod includes a flanged disk, an annular flange, a receiving space, a central bore and a rod part. The hollow piston rod closes the material discharge hole in the retracted position and being with the central bore, the holding space, and the material discharge hole in fluid communication when the hollow piston rod is in the extended position, The rod part blocks the material discharge hole of the axle sleeve to avoid it from leaking. Thus, the cosmetic container structure doesn't have the problem of leaking liquid.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The invention relates to a cosmetic container structure and more particularly to a rolling ball style cosmetic container structure that can prevent liquid overflow too much when its enclosure cap is screwed off for usage, can prevent liquid from leaking when its enclosure cap is screwed on.[0003]2. Description of Related Art[0004]Referring to FIG. 6 and FIG. 7, conventional rolling ball style cosmetic container includes a tube 1, a sleeve part 2 and a cap 5. The sleeve part 2 has a central bore 3. The sleeve part 2 is mounted a ball 4 in the central bore 3. The tube 1 contains cosmetic liquid. The sleeve part 2 is connected to the tube 1 by being sleeved inside the opening. The tube 1 comprises a first threaded part. The cap 5 comprises a second threaded part. The first threaded part of the tube 1 is threadedly connected to the second threaded part of the cap 5.[0005]However, conventional rolling ball style cosmetic contain...

AI Technical Summary

Benefits of technology

[0008]The resilient member includes a first end and a second end, the first end contacts with the resistant holding surface, the second end contacts with the annular flange of the piston rod. The annular flange is greater than the inner flange. The annular flange is stopped by the inner flange. The exterior cap has a pressing member and an inner threaded portion; the inner threaded portion threadedly connected to the threaded part of the tube. The pressing member presses the hollow piston rod and constricts the resilient member; the rod part blocks the material discharge hole of the axle sleeve from leaking. The exterior cap is removably connected to the tube to enclose the opening.

[0014]By utilizing the invention, the following advantages are obtained. First, the present invention has the function of valve assembly to be able to control the amount of discharging liquid. The present invention has the function of leaking-proof. When the cap is capped, the hollow piston rod blocks the material discharge hole tightly. Thus, the present invention doesn't have the problem of leaking liquid.

Problems solved by technology

However, conventional rolling ball style cosmetic container is short of the function of leaking-proof.

Thus, it is pretty easy to leak liquid when it is in storage or pressed.

It is very inconvenient to deal with the problem of leaking liquid.

The amount of discharging liquid can't be controlled.

Conventional rolling ball style cosmetic container often discharges too much at one time.

It leads to waste the cosmetic liquid contained in the tube.

Furthermore, the sealing of the Conventional rolling ball style cosmetic container is not reliable and thus cosmetic liquid materials contained therein may become dry or deteriorate in quality.
