Benefits of technology

The present invention is a vacuum insulation cup lid that allows the cup to maintain heat insulation for a longer period of time. The lid is formed into a hollow heat-insulated structure that prevents heat from transferring directly through the cup body and lid, resulting in delayed heat dissipation. The lid is engaged with a cup body having a similar heat-insulated function, using an inner thread and outer thread, to maintain water temperature in the cup body longer. This invention achieves better heat insulation for the cup and prevents temperature drops that can affect the quality of the beverage.

Problems solved by technology

Whereby, the heat of water filled in the cup body cannot be conducted through the cup body and cup lid directly, and heat dissipation in the cup body can further be delayed, achieving a longer heat insulation effect.

Embodiment Construction

[0010]Referring to FIG. 1, which shows a vacuum insulation cup lid of a preferred embodiment of the present invention, one end face and a side wall of the circumference of a cup lid 1 are integrally formed into a outer side wall 11 and inner side wall 12, where a heat-insulated space 13 is formed between the outer side wall 11 and inner side wall 12. In addition, an internal thread 14 is formed on an inner diameter of the inner side wall 12. the heat-insulated space 13 is a sealed space, evacuated by drawing air therefrom completely upon the manufacturing of the cup lid, allowing no medium capable of conducting heat to exist between the outer side wall 11 and inner side wall 12.

[0011]Referring to FIGS. 2 and 3, which show the combination of the cup lid 1 and a cup body 2 having a similar heat-insulated effect, the cup body 2 is a container allowing water, tea or liquid to be filled therein; it has an inner space extended downward to a certain depth, and an opening is formed on the u...

Abstract

Disclosed is a shank of a four-piece forging of golf club head. A top piece of the four-piece forging of club head forms, at a portion thereof adjacent to the shank, a two-staged structure of an outward flaring sector-shaped connection portion that is combined with the shank, whereby an abutting condition exhibiting a smooth surface is formed at a jointing site between the shank and the club head in the course of performing welding operation between the shank and the club head for reducing the amount of filling material used in carrying out the welding operation and making the welding operation, as well as the subsequent grinding operation, easier and smoother. Thus, with the quality improved, the flexibility of design can also be enhanced to reduce the machining time and the manufacturing costs.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a cup lid having a good heat insulation function.DESCRIPTION OF THE PRIOR ART[0002]A hollow heat-insulated cup is generally known as a thermos cup; it is used popularly by and welcome among people because it is heat-insulated and can prevent hands from being burnt. Conventional heat-insulated cup structures are usually a double layer structure made of stainless steel, which includes an outer wall and inner wall, and a heat insulation space is formed between the outer wall and inner wall, where the heat insulation space is evacuated during manufacturing, prevent air from becoming a heat conductive medium between the outer wall and inner wall. A user will not feel hot while holding a cup on the outer wall even if the cup is filled with boiled hot water therein because conventional hollow heat-insulated cup has a very good heat insulation effect.[0003]Although a cup body of a conventional hollow heat-insulated cup h...
