The periphery of the front page 1 is formed with a thermoplastic sealing area 4, and the width of the thermoplastic sealing area 4 from the edge is 0.5 cm. The inner edge corners of the thermoplastic sealing area 4 are chamfered. The middle part enclosed by the inner side of the thermoplastic sealing area 4 on the front page 1 is transparent. On the middle part of the transparent setting, the upper left corner i...

Embodiment 2

[0043] like figure 2As shown, a schematic diagram of the back of a shared envelope for teaching aids in one embodiment of the present invention is shown, including the back page 9 and the back of the flap 2 . The size of the back page 9 is the same as that of the front page 1, both of which are standard size: 17.6cm x 12.5cm. And an overlapping thermoplastic sealing area 10 is provided thereon for optional thermoplastic sealing with the thermoplastic sealing area 4 on the front page. The middle part enclosed by the inner side of the thermoplastic sealing area 10 on the back page 9 is also transparent and can be provided with a device pattern. A fixing device 11 is provided at a corresponding position on the back page 9 , and the fixing device 11 is used to cooperate with the fixing device 3 to fix the letter tongue 2 on the back page 9 . In this embodiment, the fixing devices 3 and 11 are snap buttons that cooperate with each other.

Embodiment 3

[0045] Due to the advantages of material (plastic material), structure (integrated molding, thermoplastic sealing structure) and surface design (information prompt), the envelope of the present invention can be placed anywhere within the scope of the teaching environment, such as setting multiple access points , students, teachers, etc. can take it anywhere, and after use, it can be easily put back at the pick-up point, so that others can take it again. The envelope of the present invention is durable, weather-resistant, dirt-resistant, easy to clean, can be used repeatedly for many times, and fully meets the sharing requirements of the shared envelope within a certain range.
