Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] refer to Figure 1 to Figure 3 , the inner and outer double-layer rotating cup lid, the cup lid 1 is provided with an inner cup 2, the bottom of the inner cup 2 is provided with a boss 3, and the inner side of the boss 3 is provided with a thread;

[0020] The mouth of the inner cup 2 is larger than the mouth of the cup lid 1, and the inner cup 2 matches the boss by setting a gap 4 on the side wall and setting the boss bolt 6 on the inner surface of the movable rotating cover 5 at the end of the cup lid 1. 3. The inner thread rotates so that the inner cup 2 shrinks inside the cup cover 1;

[0021] In the present invention, the mouth of the inner cup 2 is larger than the mouth of the cup cover 1, because the inner cup 2 can be retracted into the inner cup 2 by setting a gap 4 on the side wall, so that the inner cup 2 The side wall is always in the sta...

Abstract

The invention relates to a rotary cup cover with inner and outer layers. The cup cover is characterized in that the cup cover is provided with an inner cup, the bottom of the inner cup is provided with a protrusive column, and the inner side of the protrusive column is provided with threads; a cup opening of the inner cup is larger than a cover opening of the cup cover; by forming a notch in the side wall of the inner cup and matching the threads on the inner side of the protrusive column with a protrusive column bolt for rotation, the inner cup is contracted to the inner side of the cup cover, wherein the protrusive column bolt is arranged on the inner surface of a movable rotary cover arranged at the cover end of the cup cover; an elastic film is embedded into or wrapped on the notch inthe side wall of the inner cup. Through the movable rotary cover, the inner cup is raised from the interior of the cup cover for use by a drinker, and the situation that diseases are infected from themouth since the outer side of the cup cover is contaminated due to various reasons and is in contact with the mouth directly and other unsanitary situations can be avoided.

Description

technical field [0001] The invention relates to a cup cover, in particular to an inner and outer double-layer rotary cup cover, which belongs to the technical field of IPC classification No. A47K. Background technique [0002] The basic functions of existing drinking cups are all embodied on the cup body, and the structure of the cup cover is relatively simple, such as some cup covers can be directly used to hold water and drink after being unscrewed from the cup body. [0003] The structure of the cup cover is relatively simple, and its function is only to hold water for drinking. This type of cup cover is screwed with the cup body after only holding water and buckling upside down, so the place that can be improved is very limited. As far as the present is concerned, there is a relatively big problem in the cup lid. The cup lid holds water, and the human mouth directly contacts the outer wall of the cup lid, which is very unhygienic. The outer wall of the drinking cup is ...
