Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a paper cup, and more
particularly, to a handle of a paper cup.
[0003] 2. Background of the Invention
[0004] Different kinds of fast-food stores provide people to get
food quickly and conveniently, and people in this modern world are
so busy and they need take-out food to save time so that many
take-out containers and cups are developed for receiving food,
beverage and the like therein. However, the take-out containers and
cups do not have a handle for the users to grasp, most of the
fast-food stores have to provide plastic bags for the take-out
containers and cups. The use of plastic bags increases
environmental burden.
[0005] In order to improve the shortcoming, the conventional
take-out cup has a film to seal the open top of the cup, and the
film is larger than the open top of the cup. There are two slits
defined through the film and located corresponding to outside of
the lip portion of the cup. The portions between the slits and the
outer periphery of the film become the handles, and the handles
each have a hole. The film is heat-melted on the open top of the
cup and the handles can be formed by lifting the portions between
the slits and the outer periphery of the film. The straw can be
inserted through the holes so as to suck the beverage in the
cup.
[0006] However, the handles are a part of the film which is made by
thin plastic material and heat-melted to the open top of the cup,
so that when the user holds the handles, the handles cannot bear
the weight and probably break. Besides, the slits have to be made
before the film is fixed to the open top of the cup, so that if the
film is not precisely mounted to the desired position of the cup,
the portions for the handles can be too narrow to use.
[0007] The present invention intends to provide a handle for a
paper cup and the handle is strong and improves the shortcomings of
the conventional one.
SUMMARY OF THE INVENTION
[0008] The present invention relates to a paper cup unit and
comprises a paper cup made by water-proof paper and the paper cup
has an open top. A plastic layer is formed along the open top of
the paper cup and the plastic layer is an annular portion which has
two slits defined therethrough. A portion between each of the two
slits and the outer periphery of the plastic layer is a handle. Two
ends of each of the handles are connected with inner portion of the
plastic layer. The inner portion of the two ends of each of the
handles connected with the inner portion of the plastic layer is an
un-cut portion. The un-cut portion is a V-shaped recess or an
inverted V-shaped recess. The plastic layer is formed with the
paper cup by injection molding so as to increase the strength of
the paper cup and the handles are formed simultaneously. The
handles are made by plastic material which is the same as the
plastic layer so as to bear heavy load and the handles are securely
connected to the paper cup.
[0009] The primary object of the present invention is to provide a
paper cup unit which has a handle which is strong and reinforces
the structural strength of the paper cup.
[0010] Another object of the present invention is to provide a
paper cup unit wherein the open top is stronger so as to support
the handles.
[0011] 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
[0012] FIG. 1 is a perspective view to show the paper cup unit of
the present invention;
[0013] FIG. 2 is a perspective view to show the paper cup unit of
the present invention, wherein the handles are bent upward;
[0014] FIG. 3 is a top view of the paper cup unit of the present
invention, and
[0015] FIG. 4 shows the second embodiment of the handles of the
paper cup unit of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Referring to FIGS. 1 to 4, the paper cup unit of the present
invention comprises a paper cup 10 and a plastic layer 20.
[0017] The paper cup 10 is made by water-proof paper and has an
open top and a sealed bottom. The plastic layer 20 is formed along
the open top of the paper cup 10.
[0018] The plastic layer 20 is an annular portion and made by
bio-degradable plastic material. The plastic layer 20 is formed
with the paper cup 10 by injection molding, or the plastic layer 20
is adhered to the paper cup 10 after the plastic layer 20 is
formed. The paper cup 10 is coated with a film (not shown) so that
the plastic layer 20 is coated on the outer surface of the paper
cup 10. The plastic layer 20 includes two slits 21 defined
therethrough and the slits 21 are defined in two opposite sides of
the plastic layer 20. The two slits 21 do not communicate with each
other. A portion between each of the two slits 21 and the outer
periphery of the plastic layer 20 is a handle 22. Two ends of each
of the handles 22 are connected with inner portion of the plastic
layer. The inner portion of the two ends of each of the handles 22
connected with the inner portion of the plastic layer 20 is an
un-cut portion 23. The un-cut portion 23 is a V-shaped recess or an
inverted V-shaped recess. The two handles 22 can be easily bent
upward to form a handle so that the user can hold the handle to
carry the paper cup unit. As shown in FIGS. 1 to 3, the un-cut
portion 23 is formed on the bottom surface of the inner portion of
the plastic layer 20. The un-cut portion 23 can also be formed on
the top surface of the inner portion of the plastic layer 20.
[0019] The plastic layer 20 is formed with the paper cup 10 by
injection molding so as to increase the strength of the paper cup
10 and the handles 22 are formed simultaneously with the plastic
layer 20. The handles 22 are made by plastic material which is the
same as the plastic layer 20 so as to bear heavy load and the
handles 22 are securely connected to the paper cup 10 and are not
separated from the paper cup 10.
[0020] 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.
