EMBODIMENTS

[0024] Now referring to the accompanying drawings, the structure and use of the present invention are further described. With respect to Embodiment 1 as referred to in FIGS. 1-3, a one-handed press-open cosmetic container comprises a bottle body assembly 5 and a bottle cap assembly, the bottle body assembly is provided with humped snap ring 501 at the outer diameter of the bottle neck at the bottle body, a snap-fit groove 502 is provided at the outer diameter of the bottle neck underneath the snap ring, and the bottle cap assembly is fixed to the snap-fit groove of the bottle neck at the bottle body by a clasp 203 of the claw in the bottle cap assembly; where the said bottle cap assembly comprises a outer cap 1, claws 2 and an inner cap 3, and the clasps 203 of the claws are equally spaced and appear as L-shaped, disposed down inwardly, and the ends of the clasps are provided with inwardly humped heads, the clasps of the claws are respectively snapped into the clasp holes 301 at the top corners of the inner cap, and the clasps of the claws are snapped into the clasp holes of the inner cap and securely snap-fit to the snap-fit groove 502 of the bottle neck at the bottle body through the clasp head on one end of the clasp; the top of the claw is provided with a resilient disc surface that is driven by pressing on top to deform the clasp and expand outwardly and detach from the snap-fit groove of the bottle neck at the said bottle body, the top center of the resilient disc surface of the claws is provided with an upwardly humped button column 201, the button column extends from or is disposed in the center hole of the top of the outer cap, and the inner cap with claws is snapped into the outer cap and the outer cap is engaged with the inner cap as one piece.

[0025] The particular structure of the said inner cap and claw is described as follows: the clasp of the said claw is provided with a curved humped inner rib 202 respectively at the joint with the resilient disc surface, the button column, inner rib and clasp of the claw are molded in one piece, the inner rib of the claws is respectively abutted against the top outer end corner of the clasp hole of the inner cap, the curved corners of the inner cap are beveled upwardly and the outer side is a protrusion of the said curved corners, and the top reinforcing rib 101 in the outer cap is abutted against the top end corner at the inner rib of the claw. The clasps of the said claw are arranged symmetrically in six equally spaced pairs, the L-shaped clasps make the said resilient disc surface respectively with the annular rib joined at the inner rib and the other end of the clasp is engaged with the button column as one piece. The outer resilient disc surface of the button column of the claw is provided with an annular groove 204, and the other end of the clasp is provided with a spacing groove at the annular groove where the button column is engaged with the button column as one piece. The top of the inner cap is provided with a downwardly humped groove 302, the bottle body assembly is provided with a sealing washer 4 above the bottle neck at the bottle body of the bottle body assembly, the groove of the inner cap is snapped into the center hole of the sealing washer, and the bottom of the resilient disc surface of the claw is disposed above the groove of the inner cap.

[0026] As referred to in FIGS. 4 and 5, the top of the outer cap omits the central hole, the top of the button column of the claw is abutted against the top inside the outer cap, when a force is applied on top, the outer cap will transmit the force to the top of the claw, where the claw is forced to drive the deformation of the clasp, expand outwardly and detach from the snap-fit groove of the bottle neck at the said bottle body. As referred to in FIG. 6, the button column of the said claw is a button 6 snapped into the center of the resilient disc surface on top of the claw, with the button limit extending out or disposed in the center hole on top of the outer cap.

[0027] Press the button column of the claw by the outer cap, as contained by the reinforcing rib of outer cap and the clasp hole of the inner cap, the claw will rotate by the center of the inner rib based on the leverage principle, the vertical movement of the clasp at the button column will be turned to the horizontal movement of the clasp at the clasp. At this point, the clasp of the claw is detached from the bottle body assembly such that the cap is opened. Once opened, the bottle cap assembly is slightly popped upwards under the counteracting force of the sealing washer, which makes it more convenient to remove the bottle cap assembly.

[0028] According to the above structural characteristics of Embodiment 1 and based on Embodiment 1, as referred to Embodiment 2 of FIGS. 7 and 8, a magnet 7 is disposed on the bottom of the groove of the said inner cap, an iron scoop 8 is disposed on the bottom of the claw on top of the bottle body of the bottle body assembly, and the iron scoop is securely attached to the magnet inside the inner cap. A metal spring 9 is disposed inside the groove of the said inner cap which further boosts the resilience property of the claws.

[0029] To sum up, the cosmetic container can be opened by pressing the cap with one hand which eliminates the need of rotating or two-handed operation when opening or closing cap of the existing bottles available on the market, and enhances the perceived experience and convenient. It is operated on the principle of resilience and leverage of plastic parts. The snap-fit structure of the claw and the pressing operation structure from the top are considered as the primary technical characteristics of the cosmetic container, a LOGO is tailored for the area to press claw at the customer request, and this area may appear in round, polygonal, oval, star, heart or irregular shape.
