Description

Technical Field

[0001] The utility model belongs to the field of carton packaging box processing, and in particular relates to a pizza packaging box with a side lock. Background Art

[0002] Pizza boxes are outer packaging containers used to hold pizza and protect its shape and temperature. The most common pizza boxes on the market are made of paper materials, such as white cardboard, corrugated paper, etc. Paper pizza boxes usually have a certain load-bearing capacity and moisture-proof performance, suitable for short-distance transportation and takeaway delivery, and paper pizza boxes are environmentally friendly, recyclable, relatively low cost, and easy to promote.

[0003] A Chinese patent with authorization announcement number "CN221368055U" discloses a self-forming locking pizza box, which adds a locking tongue and an insertion port between the front side plate and the inner side plate of the bottom assembly, and adds an insertion tongue and a locking port on the cover assembly. The cover assembly is self-locked by inserting the insertion tongue into the insertion port and then inserting the locking tongue into the locking port, thereby ensuring the food safety of the pizza during transportation; secondly, protrusions 1 and 2 that protrude upward are added for limiting, so that after folding, the indented folding lines on one side of the limiting port 1 and the limiting port 2 are against the front insert plate and the rear insert plate, supporting the four sides of the bottom assembly from four directions, thereby preventing the upper cover from collapsing.

[0004] Although the above patent solves the problem of pizza box collapse and easy opening, the following problems still exist during use: 1. In order to improve the efficiency of food delivery, the pizza box usually needs to be folded in advance, and can be directly opened and used when in use. However, the above pizza box is easy to pop open after forming, which is not convenient for stacking and is extremely inconvenient to use; 2. If the self-forming lock of the pizza box is locked before stacking, on the one hand, the folding efficiency of the pizza box is reduced and the folding workload is increased. On the other hand, the lock needs to be opened first when in use, which is extremely inconvenient to use, and reduces the food delivery efficiency and cannot meet the fast-paced food delivery requirements; 3. The above pizza box only adds a lock in the middle of the front end, and the sealing on both sides only relies on the strength of the paper box itself, and the reliability is poor. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a pizza packaging box with a side lock, which is respectively limited and fixed at the front ends of both sides of the packaging box and near the middle, so that the fixation is more firm, and at the same time, the front end fixation is replaced by the two side fixation, so that the upper air vents are conveniently arranged at the front end of the pizza packaging box, and the upper air vents at the front end and the vents at the rear side can form convection, so that the steam in the box can be dissipated in time.

[0006] The pizza packaging box with side locks comprises a pizza box cover and a pizza box body, wherein the pizza box body comprises a box bottom plate, bottom side plates are respectively arranged on both sides of the box bottom plate, and side sockets are opened on the bottom side plates; the pizza box cover comprises a box cover plate corresponding to the box bottom plate, cover side plates are respectively arranged on both sides of the box cover plate, and side plugs are arranged on the cover side plates, and side ear plates are respectively arranged on both sides of one end of the side plug away from the box cover plate, and the side plug and the side ear plates correspond to the side sockets.

[0007] Preferably, the side socket is in a ladder-shaped structure, an indentation folding line is provided between the side ear plate and the side plug, and the side plug is plugged and fixed to the side socket.

[0008] Preferably, the side ear plate is a right triangle or a right trapezoid structure.
