Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention The present invention relates to a
cup and a cap, and more particularly, to a positioning device for
connecting the cap to the cup.
[0002] 2. Background of the Invention
[0003] A conventional way for take-out beverage such as coffee,
juice or bubble tea is to use a paper or plastic made cup which is
less expensive and convenient. Generally, the cup 100 for take-out
coffee is shown in FIG. 1 and includes a cap 200 which is mounted
to the open top of the cup 100 and has a through hole 201 form
which the coffee can be accessed, or through which a straw is
inserted into the cup 100. In order to add cream and sugar into the
coffee, the cap 200 has to be removed from the cup 100 so that the
user has to lift the cap 200 by fingers upward so as to remove the
cap 200 from the cup 100. During the action, the hot coffee might
splash and burn the user. The conventional cap 200 needs to be
improved.
[0004] The present invention intends to provide a positioning
device which improves the shortcomings of the conventional
positioning mechanism for connecting the cap to the cup.
SUMMARY OF THE INVENTION
[0005] The present invention relates to a paper-made cup and a cap,
wherein the cup has a plastic lip portion connected along the open
top of the cup. Multiple first engaging portions are formed on the
outer periphery of the lip portion. The cap has multiple second
engaging portions on the inside of the skirt portion of the cap.
The cap is mounted to the open top of the cup, and the first and
second engaging portions are engaged with each other.
[0006] Preferably, the lip portion, the first engaging portions and
the cap are made by bio-degradable material. Preferably, the first
engaging portions are located at even angular distance along the
outer periphery of the lip portion, and the first engaging portions
each are a block which has a first inclined surface. The second
engaging portions are located at even angular distance at the
inside of the skirt of the cap, and the second engaging portions
each have a rib which has a second inclined surface. The first and
second inclined surfaces are engaged with each other to position
the cap to the cup.
[0007] The primary object of the present invention is to provide a
cup and a cap which is mounted to the cup by the positioning device
of the present invention, the cap is easily connected to and
removed from the cup to avoid the beverage from splashing.
[0008] 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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is a perspective view to show the conventional cup
with a cap mounted thereto;
[0010] FIG. 2 is an exploded view to show the cup and the cap of
the present invention, and
[0011] FIG. 3 is a cross sectional view to show that the cap is
mounted to the cup by the positioning device of the present
invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] Referring to FIGS. 2 and 3, the paper-made cup 10 has an
open top 11 and beverage can be received in the cup 10. A plastic
lip portion 12 is connected along the open top 11 of the cup 10 and
made by bio-degradable material. Multiple first engaging portions
121 are formed on the outer periphery of the lip portion 12. The
first engaging portions 121 are located at even angular distance
along the outer periphery of the lip portion 12, and the first
engaging portions 121 each are a block which has a first inclined
surface 122 so as to be connected with the cap 20. The cup 10 is
water-proof and has a film (not shown) so that the lip portion 12
can be integrally connected to the cup 10 by way of high-frequency
wave welding or ultra-sonic welding.
[0013] The cap 20 is a circular cap and has a through hole 21
through which a straw (not shown) is inserted. Multiple second
engaging portions 22 are formed on the inside of the skirt portion
of the cap 20. The second engaging portions 22 are located at even
angular distance at the inside of the skirt of the cap 20. The
second engaging portions 22 each have a rib 221 which forms a
recess and has a second inclined surface 222. The first and second
inclined surfaces 122, 222 are engaged with each other to position
the cap 20 to the cup 10. It is noted that the lip portion 12, the
first engaging portions 121 and the cap 20 are made by
bio-degradable material.
[0014] The first engaging portions 121 and the lip portion 12 are
simultaneously formed on the cup 10 and the cap 20 is connected to
the cup 10 by engaging the first and second engaging portions 121,
22 so that the cap 20 is easily mounted upon the open top 11 of the
cup 10, and the cap 20 is also easily removed from the cup 10 while
the beverage in the cup 10 does not splash out.
[0015] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
