Deform-Proof Cup

Abstract

A novel cup is revealed. The cup is deform-proof. A body part of the cup has lateral-oriented fibers. By using the lateral-oriented fibers together with a rim part surrounding an opening part of the cup, the cup is not easily deformed on being held by hand. The present invention can be applied to cups with different heights for strengthening the body part, reducing weight of the body part and lowering production cost.

Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a cup; more particularly, relates to using lateral-oriented fibers in a body part together with a rim part to prevent the cup from deformation on being held by hand, where the present invention can thus be applied to cups with different heights for strengthening the body part, reducing weight of the body part and lowering production cost.

DESCRIPTION OF THE RELATED ART

A general paper cup comprises a body part of lateral-oriented fibers, an opening part on top of the body part and a closing part at bottom of the body part. With the paper cup, a drink is held to be drunk.

Although, the lateral-oriented fibers of the body part is used, the fibers may still be broken (perpendicularly) by a force of the user's hand when the height of the body part is longer than the diameter of the opening part (i.e. a tall cup with volume more than 500 cubic centimeters (cc)). Consequently, stiffness of the body part will be lost and the body part may further be deformed, which means the body part is not suitable for the tall cup with the height of the body part longer than the diameter of the opening part.

Hence, the prior art does not fulfill all users' requests on actual use.

SUMMARY OF THE INVENTION

The main purpose of the present invention is to use lateral-oriented fibers in a body part together with a rim part to prevent a cup from deformation on being held by hand, where the present invention can thus be applied to cups with different heights for strengthening the body part, reducing weight of the body part and lowering production cost.

To achieve the above purpose, the present invention is a deform-proof cup, comprising a body part, an opening part, a rim part and a closing part, where the body part comprises a plurality of lateral-oriented fibers; the opening part is set on top of the body part; the rim part is set to surround the opening part; and the closing part is set at bottom of the body part. Accordingly, a novel deform-proof cup is obtained.

BRIEF DESCRIPTIONS OF THE DRAWINGS

The present invention will be better understood from the following detailed descriptions of the preferred embodiments according to the present invention, taken in conjunction with the accompanying drawings, in which

FIG. 1 is the view showing the first preferred embodiment according to the present invention;

FIG. 2 is the sectional view showing the local area of the first preferred embodiment; and

FIG. 3 is the view showing the second preferred embodiment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions of the preferred embodiments are provided to understand the features and the structures of the present invention.

Please refer to FIG. 1 and FIG. 2, which are a view showing a first preferred embodiment according to the present invention; and a sectional view showing a local area of the first preferred embodiment. As shown in the figure, the present invention is a deform-proof cup, comprising a body part 1, an opening part 2, a rim part 3 and a closing part 4.

The body part 1 comprises a plurality of lateral-oriented fiber 11.

The opening part 2 is set on top of the body part 1.

The rim part 3 is set to surround the opening part 2.

The closing part 4 is set at bottom of the body part 1.

Thus, a novel deform-proof cup is obtained.

Therein, the body part 1, the rim part 3, and the closing part 4 are made of paper and height of the body part 1 is longer than diameter of the opening part 2 (i.e. a tall cup having a volume more than 500 cubic centimeters (cc)).

On using the present invention, the body part 1 contains a drink for a user to drink. When the user holds the body part 1 with his hand, a force is usually put on middle or lower part of the body part 1. Thus, upper part of the body part 1 receives a smaller force (which can be almost reduced to none). Therefore, the upper part of the body part 1 can use the lateral-oriented fibers 11 to maintain proper stiffness for strengthening the body part 1. Hence, on holding the body part 1, the lateral-oriented fibers 11 are used to prevent deformation. Furthermore, because the upper part of the opening part 2 and the rim part 3 are not affected by the user's holding the body part 1, the rim part 3 can be made of paper.

Please refer to FIG. 3, which is a view showing a second preferred embodiment. As shown in the figure, a body part 1a and a closing part 4a of a cup fabricated according to the present invention are made of paper. A rim part 3a of the cup is made of plastic. Height of the body part 1 a is shorter than diameter of the opening part 2a (i.e. a short cup). The plastic is polyproylene (PP), polyethylene (PE), polyethylene terephthalate (PET), a biomaterial, a biodegradable material, poly lactic acid (PLA) or a biomass plastic. Thus, strength of the body part 1a is maintained by the plastic rim part 3a, which further reduces weight of the body part 1a and lowers production cost.

To sum up, the present invention is a deform-proof cup, where, by using lateral-oriented fibers in a body part together with a rim part, a cup will not be easily deformed on being held by hand; and, thus, the present invention can be applied to cups with different heights for strengthening the body part, reducing weight of the body part and lowering production cost.

The preferred embodiments herein disclosed are not intended to unnecessarily limit the scope of the invention. Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
