Claims
I claim:
1. A can comprises: a main body, an upper casing disposed on a top
portion of the main body, a retained cap disposed on the upper
casing, a connection ring disposed on the retained cap, a pull ring
connected to the connection ring, a rivet button fastening the
connection ring and the retained cap together, the connection ring
having an annular head, a snap button fastening the annular head of
the connection ring and the upper casing together, the pull ring
having two hinge members enclosing the annular head of the
connection ring, and the upper casing having two vent holes to
receive the hinge members, an oblong recess, a cutting groove
surrounding the retained cap, and an inner periphery groove.
2. The can as claimed in claim 1, wherein the upper casing further
has a first guide groove to communicate with the oblong recess and
the inner periphery groove, and a second guide groove to
communicate with the oblong recess and the inner periphery
groove.
3. The can as claimed in claim 1, wherein the connection ring has
two lateral notches.
Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a can. More particularly,
the present invention relates to a can which will form a vent hole
while the can is opened.
[0002] A conventional can has a retainer cap which has a rivet
button to fasten the retainer cap on a cover of the conventional
can. When the conventional can is opened, the retainer cap will not
be detached from the conventional can entirely. Since only one
opening is formed on the cover of the can while the can is opened,
liquid in the can cannot flow out of the can quickly because air
cannot enter the can fast. If the can is shaked before opening,
bubbles will eject out of the can.
SUMMARY OF THE INVENTION
[0003] An object of the present invention is to provide a can which
will form a vent hole while the can is opened so that a liquid in
the can will flow outward quickly.
[0004] Another object of the present invention is to provide a can
which will form a vent hole while the can is opened so that a gas
in the can will flow outward from the vent hole.
[0005] Another object of the present invention is to provide a can
which has a pair of guide grooves to communicate with an oblong
recess and an inner periphery groove so that liquid remains on the
inner periphery groove will flow into the can.
[0006] Accordingly, a can comprises a main body, an upper casing
disposed on a top portion of the main body, a retained cap disposed
on the upper casing, a connection ring disposed on the retained
cap, and a pull ring connected to the connection ring. A rivet
button fastens the connection ring and the retained cap together.
The connection ring has an annular head. A snap button fastens the
annular head of the connection ring and the upper casing together.
The pull ring has two hinge members enclosing the annular head of
the connection ring. The upper casing has two vent holes to receive
the hinge members, an oblong recess, a cutting groove surrounding
the retained cap, and an inner periphery groove.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a perspective view of a can of a preferred
embodiment in accordance with the present invention;
[0008] FIG. 1A is an enlarged view taken along circle A in FIG.
1;
[0009] FIG. 2 is a partially sectional view of FIG. 1;
[0010] FIG. 3 is a first sectional schematic view illustrating a
can is opened; and
[0011] FIG. 4 is a second sectional schematic view illustrating a
can is opened.
DETAILED DESCRIPTION OF THE INVENTION
[0012] Referring to FIGS. 1 to 4, a can comprises a main body 10,
an upper casing 40 disposed on a top portion of the main body 10, a
retained cap 14 disposed on the upper casing 40, a connection ring
20 disposed on the retained cap 14, and a pull ring 30 connected to
the connection ring 20.
[0013] A rivet button 21 fastens the connection ring 20 and the
retained cap 14 together.
[0014] The connection ring 20 has an annular head 23.
[0015] A snap button 24 fastens the annular head 23 of the
connection ring 20 and the upper casing 40 together.
[0016] The pull ring 30 has two hinge members 31 enclosing the
annular head 23 of the connection ring 20.
[0017] The upper casing 40 has two vent holes 15 to receive the
hinge members 31, an oblong recess 12, a cutting groove 13
surrounding the retained cap 14, an inner periphery groove 11, a
first guide groove 17 to communicate with the oblong recess 12 and
the inner periphery groove 11, and a second guide groove 17a to
communicate with the oblong recess 12 and the inner periphery
groove 11.
[0018] The connection ring 20 has two lateral notches 22.
[0019] Referring to FIGS. 3 and 4, the pull ring 30 is pulled
upward. The connection ring 20 will be moved upward with the pull
ring 30. The lateral notches 22 cut the connection ring 20 into two
portions, so the annular head 23 of the connection ring 20 will
move upward but the rest of the connection ring 20 will not move
upward. When the user pulls the pull ring 30 with a strong force,
the whole connection ring 20 will move upward.
[0020] Referring to FIG. 4, a drinking hole 16 will be formed while
the retained cap 14 moves downward. Then the rivet button 21 is a
fulcrum.
[0021] The invention is not limited to the above embodiment but
various modification thereof may be made. Further, various changes
in form and detail may be made without departing from the scope of
the invention.
