It is worth mentioning that the paper lid of the present invention is not limited to each lid side panel 52 being a double-layer side panel with inner and outer layers 522, 521 and gaps 523 as mentioned above, as long as there is at least one lid side panel. The plate 52 is the double-layer side plate, and at least one horizontal extension plate 41 of the paper container 20 is inserted into the gap 523 of the double-layer side plate, so that the paper lid 50 can be stuck on the paper container 20 to a certain extent. effect. In addition, the entire paper cover 50 in the aforementioned embodiment is made of a single paper material. Therefore, the inner layer 522 and the outer layer 521 of each double-layer side panel are made of the same paper material. The connecting surface 522b of the inner layer 522 and The inner surface 521b of the outer layer 521 is formed from the same surface of the paper material, but the invention is not limited thereto. For example, the inner layer 522 can also be made of another paper material and then adhered to the inner surface 521b of the outer layer 521. Furthermore, the connection surface 522b of the inner layer 522 of the double-layer side panel in the aforementioned embodiment is completely attached to the inner surface 521b of the outer layer 521, thereby achieving a better fixing effect. However, the connection of the inner layer 522 of the double-layer side panel The surface 522b may also be only partially attached to the inner surface 521b of the outer layer 521, such as those provided in the following two embodiments.

Please refer to Figure 6. The paper cover 50' provided in the second preferred embodiment of the present invention is similar to the aforementioned paper cover 50, except that the cover side panel 52 (double layer) of the paper cover 50' in this embodiment is The inner layer 522 of the side panel can be divided into an upper block 522c and a lower block 522d. The upper block 522c is adjacent to the top edge 522a of the inner layer 522 and is not attached to the outer layer 521. The lower block 522d is higher than the upper block. 522c is further away from the central top plate 51 and attached to the outer layer 521 . Thereby, the upper section 522c of the inner layer 522 of the double-layer side panel 52 can slightly elastically swing relative to the outer layer 521, which not only makes the gap 523 between the top edge 522a of the inner layer 522 and the lower surface 511 of the central top plate 51 smaller. The large depth (compared to the gap 523 shown in Figure 3) allows the horizontal extension plate 41 of the paper container 20 to be inserted into the gap 523 more firmly, and the horizontal extension plate 41 of the paper container 20 to be inserted into the gap. 523, the upper block 522c of the inner layer 522 of the double-layer side panel will make a slight sound due to elastic swing, so that the user can more clearly know that the paper lid 50' and the paper container 20 are locked with each other.

Please refer to Figure 7. The paper lid 50" provided by a third preferred embodiment of the present invention is similar to the aforementioned paper lid 50, except that the lid side panel 52 (double layer) of the paper lid 50" of this embodiment is The inner layer 522 of the side panel can distinguish a middle block 522e (roughly the block surrounded by the dotted line in Figure 7), and separate positions. There are two side blocks 522f on both sides of the middle block 522e (only one side block 522f is shown in Figure 7). The side block 522f is adjacent to one edge 522g of the inner layer 522 and is not attached to the outer layer 521. Only The middle block 522e is attached to the outer layer 521. Thereby, the side sections 522f of the inner layer 522 of the double-layer side panel can slightly elastically swing relative to the outer layer 521, so that the gap 523 between the top edge 522a of the inner layer 522 and the lower surface 511 of the central top panel 51 can be in the side area. The location of the block 522f has a greater depth (compared to the gap 523 shown in Figure 3), so that the horizontal extension plate 41 of the paper container 20 can be inserted into the gap 523 more firmly, and the effect of the paper container 20 When the horizontal extension plate 41 is inserted into the gap 523, the side section 522f of the inner layer 522 of the double-layer side plate will make a slight sound due to elastic swing, which can let the user know more clearly that the paper lid 50" has been connected with the paper lid. The containers 20 snap into each other.

Finally, it must be stated again that the constituent elements disclosed in the foregoing embodiments of this invention are only examples and are not used to limit the scope of this case. Substitutions or changes of other equivalent elements should also be within the scope of the patent application of this case. covered.
