Benefits of technology

The design effectively prevents heat transfer, allows for easy lid operation, and facilitates the assembly and disassembly of the cups, enabling the easy insertion and exchange of advertisement sheets, enhancing user safety and manufacturing efficiency.

Problems solved by technology

The conventional cup has problems that a user may be damaged by hot heat as the heat of the stuff of the cup is transferred to the hands of a user.
The user may drop a hot cup, thereby causing a burn.
It costs too much for manufacturing a mold and forming a pattern and design.
When opening or closing the conventional double structure cup by rotating the lid, the inner cup is not fixed to the outer cup, namely, it rotates idle, so that opening and closing the lid are not easy.
In this case, exchanging the insertion sheet is not easy, and assembling and disassembling works are not easy.

Embodiment Construction

[0020]The construction and operation of the present invention will be described with reference to the accompanying drawings.

[0021]FIG. 1 is an assembled cross sectional view of a double structure cup according to an embodiment of the present invention, FIGS. 2A and 2B are front cross sectional and bottom views of an inner cup of FIG. 1, FIGS. 3A and 3B are front cross sectional and bottom views of an outer cup of FIG. 1, and FIG. 4 is a front view of a lid of FIG. 1.

[0022]As shown therein, the double structure cup according to the present invention comprises an inner cup 100, an outer cup 200, a lid 300 and an insertion sheet 400.

[0023]The inner cup 100 is cylindrical and has a side surface 110 and a bottom surface 120 with an upper side of the same being open for storing a certain stuff. The side surface 110 is gradually narrowed in a downward direction.

[0024]The inner cup 100 stores a certain stuff such as hot coffee, tea, milk or something or stores a certain stuff such as cold b...

Abstract

A double structure cup is disclosed, which is characterized in that a plurality of polygonal male protrusions are protruded from a bottom surface of the inner cup in a downward direction, and a plurality of concave protrusions are formed and engaged with the male protrusions on a bottom surface of the outer cup in an upward direction, so that as the male protrusions are engaged with the concave protrusions, the inner cup does not rotate along with the lid when the lid is rotated for opening and closing.

Description

[0001]This application is a divisional of U.S. Ser. No. 11 / 966,825, filed Dec. 28, 2007 and claims priority to Korean patent application KR 10-2007-83081, filed Aug. 18, 2007, the disclosures of which are incorporated by reference.TECHNICAL FIELD[0002]The present invention relates to a double structure cup, and in particular to a double structure cup in which an inner cup and an outer cup are engaged in a polygonal protrusion engagement structure. So, when a lid is opened or closed by rotating the lid, an inner cup does not rotate along with the lid while keeping an engaged state with the outer cup.BACKGROUND ART[0003]Generally, a cup is used as a receptacle for storing beverage or liquid food or being used when drinking something. It has a certain thickness and an open upper side.[0004]The above cup stores hot coffee, tea or milk or stores cold beverage.[0005]The conventional cup has problems that a user may be damaged by hot heat as the heat of the stuff of the cup is transferred ...
