Description

A kind of degradable environmentally friendly paper cup and its preparation process

Technical field

The invention belongs to the field of paper cups, specifically a degradable and environmentally friendly paper cup and its preparation process.

Background technique

Paper cup is a kind of paper cup that is easy to carry and use, and is cheap. It is a common drinking tool in many homes and public places.

With the development of society, people's environmental awareness continues to increase, so people have improved the raw materials of paper cups, developed degradable environmentally friendly paper, and applied it to paper cups, producing degradable environmentally friendly paper cups.

Research has found that existing degradable environmentally friendly paper cups have certain drawbacks when used;

First, existing degradable environmentally friendly paper cups have the same structure as existing disposable paper cups. When hot water is filled inside, the temperature of the entire environmentally friendly paper cup is relatively high, making it relatively hot to use;

Secondly, the existing degradable environmentally friendly paper cups have the same structure as existing cups. They only have the function of holding water, and their functions are relatively simple and do not meet people's usage requirements.

Contents of the invention

In order to overcome the shortcomings of the existing technology, the embodiments of the present application provide a degradable environmentally friendly paper cup and its preparation process. The technical solution adopted to solve the technical problem is:

A degradable and environmentally friendly paper cup, including a paper cup body, an anti-scalding cover and a shielding part;

The upper end surface of the paper cup body is provided with a bayonet;

The anti-scalding cover is arranged at the middle position of the outer surface of the paper cup body;

The main body of the shielding part is located inside the main body of the paper cup, and is engaged with the bayonet;

Wherein, the shape of the anti-scalding cover is annular, and the anti-scalding cover is arranged in two layers, and its inner layer is adhered to the outer surface of the paper cup body.

The shape of the anti-scalding cover is ring-shaped, which is convenient to hold. The double-layer structure has better anti-scalding effect.

The invention records a degradable and environmentally friendly paper cup. The outer surface of the main body of the paper cup is provided with an anti-scalding cover, and the anti-scalding cover adopts a double-layer structure. At the same time, the inner and outer layers of the anti-scalding cover are made of annular convex Setting, it can greatly improve the anti-scalding effect, and the inner bulges of the anti-scalding cover fit with the outer bulges, which can improve the strength of the bulges and effectively prevent the collapse of the bulges, thus making the anti-scalding cover The protrusions are not in direct contact with the outer surface of the paper cup body, and the anti-scalding effect is better.

Preferably, the other end of the hanging portion is bent into an arc-shaped engaging portion, and the engaging portion is engaged with the bayonet to prevent the hanging portion from swinging around during use.

The invention records a degradable and environmentally friendly paper cup. When making tea, take out the shielding part from the base part, place the tea leaves, place it in the main body of the paper cup, and move the hanging part so that the clamping part at one end of the hanging part It can be connected with the bayonet and can be used directly, which can effectively prevent the tea leaves from floating on the water, making it more convenient when drinking and having better use effect.

Preferably, several sets of limit bars are fixedly installed on the inner wall of the base part, and the blocking part is provided on the lower end surface of the base part. At this time, it is in the stowed state. At this time, the hanging part is bent and set, and the hanging part and the base are The limiting strip is in close contact with the bottom surface of the shielding part, thereby directly limiting the position of the shielding part.

Preferably, a preparation process for degradable environmentally friendly paper cups includes the following steps:

①. Prepare each component of the paper cup, and connect the main part and the base part to generate the main body of the paper cup;

① The step is the production step of the existing paper cup. This patent does not improve it, so it will not be described too much.

②. Install an anti-scalding cover on the outer surface of the paper cup body;

③. Coating the main body and shielding part of the paper cup equipped with the anti-scalding cover. The coating steps are the same as those of the existing paper cup coating. This patent does not improve it, so it will not be described too much;

④. Fold the hanging part and snap the shielding part to the bottom of the base part.

To sum up, the present invention includes at least one of the following beneficial technical effects:

First, the present invention records a degradable and environmentally friendly paper cup. The outer surface of the main body of the paper cup is provided with an anti-scalding cover, and the anti-scalding cover adopts a double-layer structure.
