Embodiment Construction

[0011] Referring to FIGS. 2 and 3, the bottle cap assembly of the present invention comprises a spout member 3 having a first end 30 which has a threaded inner periphery 301 that is threadedly connected to a spout 60 of a bottle 6. A shank 31 is connected to the first end 30 and a passage is defined through the spout member 3. A seal member 311 is located in an opening 310 in a second end opposite to the first end 30 of the spout member 3 so as to form an annular opening between an inner periphery of the opening 310 and the seal member 311. An annular ridge 312 extends outward from an outer periphery of the second end of the shank 31 and a groove 313 is defined in the outer periphery of the second end of the shank 31 and located beneath the annular ridge 312.

[0012] A cap 4 is movably mounted to the second end of the shank 31 and has a hole 40 defined therethrough which has a stepped inner periphery such that the seal member 311 is disengageably engaged with the hole 40. A protrusio...

Abstract

A bottle cap assembly includes a spout member mounted to a bottle and includes a shank. A passage is defined through the spout member and a seal member is located in an opening in a distal end of the spout member. A cap is movably mounted to the distal end of the shank and has a hole defmed therethrough which has a stepped inner periphery. The seal member is disengageably engaged with the hole. An operation member is movably mounted to the shank and the cap is engaged with the operation member such that when pulling the operation member, the cap is pulled away from the sealing member. The operation member has a volume which is larger than that of the cap.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a bottle cap assembly which includes a operation member movably mounted to the spout member and connected to the cap which is moved upward by pulling the operation member to open the cap assembly. BACKGROUND OF THE INVENTION [0002] A conventional water or juice bottle shown in FIG. 1 generally includes cap assembly includes a cap 1 which is movably mounted to a spout member 2 threadedly mounted to the opening of the bottle. A flange 12 extends outward from a top of the cap 1 and a stepped hole 10 is defined through the cap 1. A protrusion 13 extends inward from the inner periphery of the stepped hole 10 so as to be engaged with an annular ridge 20 and received in a groove 21 located beneath the ridge 20 on the spout member 2. The protrusion 13 is allowed to move over the annular ridge 20 when pulling the cap 1 such that a gap is defined between the cap 1 and the seal member 22 on the spout member 1 and water or juice may...
