The present invention relates to a bottle cap assembly, and more particularly, to a rotatable bottle cap connected with a hose.
A conventional water bottle cap with a hose is disclosed in CN 201381022 and includes a cap and a hose, wherein the cap has a recessed area from which a tube is extended and the hose is mounted to the tube. A suction unit is pivotably connected to the recessed area and includes a pivot and a mouthpiece which is securely connected to the pivot. The mouthpiece has a passage which communicates with the tube. The pivot includes a protrusion which positions the suction unit when the suction unit is in closed position. The benefits of the cap is that the protrusion well positions the suction unit when not in use so that the liquid in the bottle cannot not flow out from the suction unit. However, the protrusion tends to be worn out after frequent uses and is loosened or even disengaged from the recess in the recessed area. This restricts the reliability and durability of the product. Besides, there is no dust cap provided and the users have to directly operate the suction unit and directly touch the suction part which may be contaminated.
The present invention intends to provide a bottle cap assembly to improve the shortcomings of the above mentioned conventional cap assembly.
The present invention relates to a bottle cap assembly and comprises a mount, a hose unit, a mouthpiece unit and a dust cap. The mount has an air hole and a lug, and two recesses are defined in the inside of the lug. An inlet valve 14 is engaged with the air hole and a tubular portion is located in the mount 1 and extends toward a bottle. The tubular portion has two spiral ribs and a seal member is located at a central portion of the tubular portion. The hose unit is connected between the tubular portion and a hose which is inserted into a bottle. The mouthpiece unit is connected to the mount and comprises a rotatable member, a seal ring and a mouthpiece. The rotatable member has spiral grooves defined in a lower portion thereof, and a knob and a first engaging groove are located on the top of the rotatable member. A passage is defined through the rotatable member and a sealing groove is defined in the outer surface of the mediate portion of the rotatable member. A seal ring is engaged with the seal groove. The rotatable member is engaged within the tubular portion and the spiral ribs are engaged with the spiral grooves. The seal member is located in the passage and seals the mouthpiece unit when the rotatable member is located at the lowest position. When the knob is rotated, the spiral grooves are moved upward along with the spiral ribs and the passage is separated from the seal member to open the mouthpiece unit, so that the user can suck the liquid in the bottle via the mouthpiece. The dust cap is mounted to the top of the mount and accommodating the mouthpiece unit. The dust cap has a locking point at the inside thereof so that when the dust cap is mounted to the mouthpiece, the locking point is engaged with the knob to secure the dust cap. An ejection valve is connected to the rotatable member which is secured by using a pressing ring.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The mount 1 has an air hole 12 defined through the top thereof and an inlet valve 14 engaged with the air hole 12. The mount 1 further has a lug 11 on the top thereof and two recesses 13 are defined in the inside of the lug 11. A tubular portion 15 is located in the mount 1 and extends toward a bottle 5 to which the mount 1 is connected. The tubular portion 15 has two spiral ribs 151 on the bottom thereof and a seal member 152 is located at the central portion of the tubular portion 15. The knob 312 has a gap 3121 defined in the inside thereof. The mouthpiece 33 includes a protrusion 331. The dust cap 4 has a lever 41 which has two bosses 411 on two sides of a distal end thereof, the bosses 411 are engaged with the recesses 13 of the lug 11.
