Cap With Suction Unit For Cup
A cap with a suction unit includes a cap having a semi-spherical recess defined in a top thereof and communicating with an outlet defined through an inner end of the semi-spherical recess. A first air hole is defined through an inner periphery of the semi-spherical recess. A suction member has a spherical base, which is rotatably engaged with the semi-spherical recess, and a tube extends from the spherical base. A passage is defined through the spherical base and the tube. A second air hole is defined through the spherical base. The passage and the second air hole are respectively in communication with the outlet and the first hole when the suction member is pivoted to a first position, and the passage and the second air hole are respectively not in communication with the outlet and the air hole when the suction member is pivoted to a second position.
1. Field of the Invention
The present invention relates generally to a cap with a suction unit for a cup, and the suction unit is suitable to suck particulate food in the beverage.
2. The Prior Arts
A conventional beverage cup shown in
As shown in
However, due to the curvature of the base B1 of the suction member B, the outlet A5 in the flat surface of the recess A1 is not well sealed. This restricts the size of the outlet A5, and pulps or particulate food in the beverage are difficult to be sucked via the suction member B.
SUMMARY OF THE INVENTIONA primary objective of the present invention is to provide a cap with a suction unit for a cup, and the suction unit allows the user to suck particulate food in the cup. Besides, the suction unit resolves the shortcoming of the conventional suction unit that the dust might contaminate the beverage via the hole in the cap.
The solution of the present invention is to provide a suction member with a spherical base which is rotatably engaged with a semi-spherical recess in the cap so that the outlet in the cap can be completely sealed by the base, and furthermore a passage defined through the suction member can be made large enough to suck particulate food in the beverage.
The suction unit of the present invention also prevents dust from entering the cup by arranging air holes in the semi-spherical recess.
According to the present invention, a cap with a suction unit includes a cap having a semi-spherical recess defined in a top thereof and an outlet defined through an inner end of the semi-spherical recess. At least one first air hole is defined through an inner periphery of the semi-spherical recess. A suction member has a spherical base which is rotatably engaged with the semi-spherical recess, and a tube extends from the spherical base. A passage is defined through the spherical base and the tube, and at least one second air hole is defined through the spherical base. The passage and the second air hole are respectively in communication with the outlet and the first air hole when the suction member is pivoted to a first position, such that the user can suck the beverage in the cup. The passage and the second air hole are respectively not in communication with the outlet and the first air hole when the suction member is pivoted to a second position.
Two flanges extend from the top of the cap and an opening defined by the semi-spherical recess is located between the two flanges. Each flange includes an inner surface which has the same curvature as the semi-spherical recess. The suction member is then restricted to be pivoted in upward and downward directions.
An elongate groove is defined in the top of the cap and the tube of the suction member is removably engaged with the groove when the suction member is located in the second position.
The present invention will be apparent to those skilled in the art by reading the following detailed description of a preferred embodiment thereof, with reference to the attached drawings, in which:
With reference to the drawings and in particular to
A suction member 2 includes a spherical base 21 and a tube extends from the base 21. The spherical base 21 is shaped to be rotatably engaged with the semi-spherical recess 11. A passage 22 is defined through the spherical base 21 and the tube. At least one second air hole 23 is defined through the spherical base 21, and preferably, the at least one second air hole 23 is defined in a lateral surface of the spherical base 21.
A tubular extension extends from an underside of the cap 1 and communicates with the outlet 15, and a straw 4 has one end mounted to the tubular extension, the other end is inserted into the cup 3 on which the cap 1 is mounted.
When in use, as shown in
Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
