Embodiment 1

[0038] Pour freshly boiled water into the cup body 1 and put it on the table to be cooled. At this time, the high-temperature discoloration layer 6 on the outer wall of the cup body 1 changes from original white to black. Deformation occurs under the action of pressure, and the needle tube 10 moves downward under the drive of the bottom top 6 of the cup to puncture the waterproof membrane 12. When the water in the cup is drunk, the top 6 of the cup returns to its original shape, driving the needle tube 10 Return to the original position. At this time, the water in the cavity 9 will flow down from the position where the waterproof membrane 12 is pierced along the water seepage hole 11 under the action of gravity. At this time, the water-changing layer 5 changes color, from white to red, and passes through the high-temperature color-changing layer. Discoloration with the hydrochromic layer can remind subsequent users that the paper cup has been used.

Embodiment 2

[0040] Pour water that has cooled to normal temperature into the cup body 1, the top 6 of the bottom of the cup is deformed under the action of water pressure, and is sunken downwards, the needle tube 10 moves downwards driven by the top 6 of the cup bottom, and the waterproof membrane 12 is tied When the water in the cup is finished drinking, the top 6 of the bottom of the cup returns to its original shape, driving the needle tube 10 to return to its original position. At this time, the water in the cavity 9 is under the action of gravity, from the position where the waterproof membrane 12 was pierced, along the water seepage hole. 11 shed down, and now the water color-changing layer 5 changes color, from white to red, which can remind the latecomers that the paper cup has been used and prevent the paper cup from being used again.

Abstract

The invention provides a paper cup capable of preventing secondary use. The paper cup comprises a cup body and a cup bottom, wherein the inner wall of the cup body is adhered to the cup bottom, the cup bottom is of a hollow structure, the bottom of the cup bottom is positioned above the bottom of the cup body, the top of the cup body is of an open type structure, the top of the cup body is made tobe winding-drum-shaped and forms the cup edge, a high-temperature color change layer made of temperature measurement test paper is adhered to the outer wall of the cup body, a water color change layer made of moisture inspection test paper is adhered to the bottom of the cup bottom, the inside of the cup bottom is filled with liquid, a water seepage hole is arranged between the cup bottom and thewater color change layer in a penetrating manner, and a layer of waterproof film coats the top of the water seepage hole. For the paper cup, through the high-temperature color change layer, the papercup has color change after hot water is added into the paper cup, through the water color change layer, when water exists in the paper cup, the water color change layer has color change, due to the adoption of the technical scheme, the paper cup has the advantage that the obvious appearance change can be formed when the water cup is used, and thus the secondary use of the paper cup can be prevented.

Description

technical field [0001] The invention relates to a paper cup for preventing secondary use, which belongs to the field of daily necessities. Background technique [0002] A paper cup is a kind of paper container made by mechanically processing and bonding base paper (white cardboard) made of chemical wood pulp, with a cup-shaped appearance. The paper cups used for frozen food are coated with wax, which can hold ice cream, jam and butter, etc.; the paper cups used for hot drinks are coated with plastic, resistant to temperatures above 90°C, and can even be filled with water. Paper cups are characterized by safety, sanitation, lightness and convenience. It can be used in public places, restaurants, and restaurants. It is a disposable product, but the existing paper cups have no obvious change in appearance after being filled with water, and there is no obvious difference from unused paper cups after air drying. Paper cups are no longer safe and hygienic to use. Contents of t...
