Problems solved by technology

[0005] The solution is to use a ventilation channel that runs through the top and bottom, and the heat on the cup wall is taken away, which can solve the anti-scalding problem very well, but the inner cup can only be observed from the cup mouth, and is affected by the gas emitted from the ventilation channel. not easy to observe

Embodiment 1

[0022] Such as figure 1 , figure 2 and image 3 As shown, the paper-plastic cup includes an inner cup 1 made of transparent plastic and a cylindrical jacket 2 outside the inner cup 1. The inner cup 1 and the cylindrical jacket 2 form a double-layer anti-scald structure. On the basis, Observe the condition of the inner cup 1 by setting linearly arranged strip-shaped holes 3, and form suitable air convection through one or two linearly arranged strip-shaped holes 3 and other structures, so as to keep the upper part of the paper-plastic cup to maintain heat. The lower section improves scald protection. details as follows:

[0023] The inner cup 1 is made of transparent plastics such as PP or PE, and its shape can be a general cup with a taper.

[0024] The cylindrical jacket 2 is made of paper material, and its upper and lower ends have curling structures that increase the distance from the inner cup 1 wall. Between the outer walls of the inner cup 1 there are heat insulati...

Embodiment 2

[0029] The content of embodiment 2 is basically the same as that of embodiment 1, the difference lies in the shape of the inner cup 1 . In this example, the side wall of the inner cup 1 is a straight cylinder side wall, and the cylindrical outer casing 2 is tapered, and the diameter of the upper end is larger than that of the lower end. Increasing the heat insulation gap 4 and the straight side wall can speed up the flow of hot air and prevent the block of air flow on the outer wall of the inner cup 1 .

Abstract

The invention provides a paper-plastic cup, and belongs to the technical field of paper cups. The technical problem that the condition of an inner cup of an existing paper-plastic cup is inconvenientto observe is solved. The paper-plastic cup comprises an inner cup made of transparent plastic and a cylinder-shaped outer sleeve sleeving the inner cup, the upper end and the lower end of the cylinder-shaped outer sleeve are connected to the outer wall of the inner cup respectively, and heat insulation gaps which are in communication are formed between the middle of the cylinder-shaped outer sleeve and the outer wall of the inner cup. A plurality of strip-shaped holes communicating the heat insulation gaps with the outside are formed in the side wall of the cylinder-shaped outer sleeve in theaxial direction of the cylinder-shaped outer sleeve, the strip-shaped holes are arranged in a straight line, protruding openings protruding out of the side wall of the cylinder-shaped outer sleeve are formed between the adjacent strip-shaped holes, and the protruding openings are in communication with the heat insulation gaps. According to the scheme, the linearly-arranged strip-shaped holes areformed in the cylinder-shaped outer sleeve to observe the condition of the inner cup, the inner cup can be observed from the side wall of the paper-plastic cup, and on the basis, a good anti-scaldingeffect is achieved.

Description

technical field [0001] The invention belongs to the technical field of paper cups, and relates to a paper-plastic cup, in particular to a double-layer paper-plastic cup. Background technique [0002] The paper-plastic cup is a double-layer disposable cup. The inner cup is made of plastic, which can be widely used for filling various media. Coupled with the support of the outer paper jacket, its application range is wider. Forming a thermal insulation gap between the inner cup and the outer jacket is one of the anti-scald solutions for double-layer paper-plastic cups, and it is the most widely used solution. Since the jacket needs to form a thermal insulation gap with the inner cup, it needs to cover the entire outer circumference of the inner wall, so the remaining medium of the inner cup cannot be observed from the side of the paper-plastic cup. [0003] On the basis of this double-layer paper-plastic cup anti-scald solution, some improved anti-scald solutions have also ap...
