Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a disposable cup holder for holding a cup and more particularly, to a scald-preventive disposable cup holder.

2. Description of the Related Art

Disposable paper or plastic cups are intensively used in coffee shops, fast-food chain stores, drive-through restaurants, etc., for holding coffee, beverage, soup, or the like for takeout ordering. However, it is scalding to hold a hot cup directly with the hands. Some shops may provide clients with a paper cup holder for holding the cup, preventing direct contact of the hands with the cup. However, conventional paper cup holders simply have a barrel-like cup body without handle. A cup holder of this design simply postpones transferring of heat energy from the cup to the user's hand. The high temperature of the content carried in the up will still be transferred to the user's hand, causing the user to feel uncomfortable.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a cup holder, which has a scald-preventive handle that effectively reduces transferring of heat energy from loaded cup to the user's hand. It is another object of the present invention to provide a scald-preventive cup holder, which is made of inexpensive paper material for disposable use. It is still another object of the present invention to provide a scald-preventive disposable cup holder, which is easy and inexpensive to manufacture.

To achieve these and other objects of the present invention, the scald-preventive disposable cup holder comprises an endless peripheral wall formed of paper material, and a through hole defined by the endless peripheral wall and extending through top and bottom sides thereof, wherein at least one z, 900 -shaped cut is formed in the endless peripheral wall for enabling a part of the endless peripheral wall to be turned outwards from the endless peripheral wall to form at least one handle.

Further, protruding ribs may be formed on the inner or outer surface of the endless peripheral wall to provide a heat isolation effect.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, two certain thickness paper sheet materials are arranged in a stack and stamped into a [0033] cup holder 1 subject to the desired shape. During shape forming, two substantially
-shaped cuts 11 are formed in the cup holder 1 at two opposite sides, thereby forming two handles 13. Further, two vertical folding lines are formed in the cup holder 1 at two sides and extended to the top and bottom edges of the cup holder 1 for folding. Each handle 13 has one side connected to the cup holder 1 by a connection line 12, which allows the respective handle 13 to be turned in and out of the respective
-shaped cut 11, and a finger hole 14. The finger hole 14 can be made having any of a variety of shapes. When extended out, the finished cup holder 1 is shaped like a tapered stub tube for holding a cup. Further, the bottom edge 10 of the cup holder 1 is smoothly upwardly curved (this will be explained further).
The two [0034] handles 13 are respectively turned out of the respective
-shaped cuts 11 of the cup holder 1 (see FIG. 2), and then the cup holder 1 is extended out (stretched into the three-dimensional operative shape). Alternatively, the cup holder 1 can be extended out before turning the handles 13 out of the respective
-shaped cuts 11 of the cup holder 1. Thus, a cup 2 can be inserted into the cup holder 1 and rested therein as shown in FIGS. 3 and 9. When using the cup holder 1 to hold a cup 2 containing hot water, the user can hold the handles 13 with the fingers, preventing direct touch of the fingers with the peripheral wall of the cup holder 1 that absorbs heat from the hot water contained in the cup 2. As indicated above, the cup holder 1 is shaped like a tapered stub tube having a relatively bigger inner diameter in the top side and a relatively smaller inner diameter in the bottom side, it holds the cup 2 firmly in place. Further, because the bottom edge 10 of the cup holder 1 is smoothly upwardly curved, it has a certain prestress for supporting the load of the cup and the contained substance in the cup.
The [0035] cup holder 1 can be made of a double-layer paper material, having the outer layer of the double-layer paper material properly cut to form the desired handles 13 and the inner layer of the double-layer paper material printed with a logo at the location corresponding to the handles 13 (see FIG. 3A).
According to the second embodiment of the present invention as shown in FIGS. [0036] 4˜6, two certain thickness paper sheet materials are arranged in a stack and stamped into a cup holder 1 shaped like a tapered stub tube for holding a cup. During shape forming, one substantially
-shaped cut 11 is formed in the cup holder 1, thereby forming a handle 13. The handle 13 has one side connected to the cup holder 1 by a connection line 12, which allows the handle 13 to be turned in and out of the
-shaped cut 11, and a finger hole 14. The finger hole 14 can be made having any of a variety of shapes.
According to the third embodiment of the present invention as shown in FIGS. 7 and 8, the [0037] cup holder 1 has vertical ribs 11 protruded from and equiangularly spaced around the outside wall. The vertical ribs 11 increase the wall thickness of the cup holder 1. When holding the cup holder 1 with the fingers, the fingers are in contact with the vertical ribs 11, less heat energy will be transferred from the cup held in the cup holder 1 to the user's fingers.
According to the fourth embodiment of the present invention as shown in FIGS, [0038] 10 and 11, the cup holder has vertical ribs 11 protruded from and equiangularly spaced around the inside wall. The vertical ribs 11 increase the wall thickness of the cup holder 1. When holding a cup with the cup holder 1, the vertical ribs 11 support the cup in place, and therefore less heat energy is transferred from the cup held in the cup holder 1 to the peripheral wall of the cup holder 1.
Further, corrugated paper material may be used to make cup holders, achieving the desired heat insulation effect. A cup holder can also be made having raised portions protruded from the inside or outside wall. [0039]
According to the fifth embodiment of the present invention as shown in FIG. 12, the [0040] cup holder 1 is made having the same inner diameter in the top side as well as the bottom side for holding a cylindrical can food or beverage.
According to the sixth embodiment of the present invention as shown in FIGS. 13 and 14, the [0041] cup holder 3 is formed of two narrow elongated strips of hard paper. The two narrow elongated strips of hard paper of the cup holder 3 each have two extension lugs 31 at the ends. The extension lugs 31 of the two narrow elongated strips of hard paper are bonded together, forming a respective handle. After bonding of the extension lugs 31, the two narrow elongated strips of hard paper of the cup holder 3 are stretched into an open status, thereby forming a circular cup holder.
According to the seventh embodiment of the present invention as shown in FIGS. 15 and 16, the [0042] cup holder 3 is formed of two narrow elongated strips of hard paper. The two distal ends of the narrow elongated strips of hard paper are respectively bonded together. Each narrow elongated strip of hard paper has an extension lug 31 at one end for forming a handle. After bonding of the ends of the two narrow elongated strips of hard paper, the two narrow elongated strips of hard paper are stretched into an open status, thereby forming a circular cup holder.
Alternatively, the [0043] cup holder 3 can be made having a rectangular shape with extension lugs 31 at two sides as shown in FIG. 17. FIG. 18 shows another alternate form of rectangular cup holder according to the present invention.
According to still another alternate form of the present invention as shown in FIG. 19, the [0044] cup holder 3 is formed of a narrow strip of hard paper curved into a barrel-like shape, having two extension lugs 31 respectively extended from the two distal ends and bonded together, thereby forming a handle.
According to still another alternate forms of the present invention as shown in FIGS. 20 and 21, hole or holes [0045] 311 are formed in the bonded extension lugs 31 of the cup holder 3. Making a cut 312, for example, a crossed cut (see FIGS. 20 and 21), I-cut (see FIG. 22), or double Y-end cut (see FIG. 23) on the bonded extension lugs 31 and then inserting the finger through the cut 312 form a hole 311 in the bonded extension lugs 31 of the cup holder 3.
FIG. 19A shows still another alternate form of the present invention. According to this embodiment, the [0046] cup holder 3 is formed of a narrow strip of hard paper curved into a barrel-like shape, having two extension lugs 31 respectively extended from the two distal ends and bonded together, thereby forming a handle. Each extension lug 31 has a first lug portion 31A, a second lug portion 31B, a third lug portion 31C, and a respective vertical folding line 31D between the first lug portion 31A and the second lug portion 31B and between the second lug portion 31B and the third lug portion 31C. Each extension lug 31 is folded inwards along the respective vertical folding lines 31D to have the first lug portion 31A and the second lug portion 31B bonded together and the third lug portion 31C bonded to the inside wall of the cup holder 3. Further, the cup holder 3 has a vertical folding line 31E on the middle remove from the handle (the extension lugs 31). Through the vertical folding line 31E, the cup holder is collapsed into a flat manner.
A prototype of scald-preventive disposable cup holder has been constructed with the features of FIGS. [0047] 1˜23. The scald-preventive disposable cup holder functions smoothly to provide all of the features discussed earlier.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims. [0048]
