In addition, "top", "bottom", "left", "right", "top", and "bottom" used in the following description should not be construed as limiting the present invention.

1 to 3 show a food packaging box provided by the present invention. The packaging box includes a box body 100 and a box cover 200. A food cavity 110 is provided inside the box body 100, and the interior of the food cavity 110 can accommodate unused food. The food cavity 110 has an opening 111 for taking and placing the food in the mouth, and the opening 111 can be closed by the cover 200 . In the present invention, the box cover 200 and the box body 100 may be separable or inseparable. When the box cover 200 is covered on the box body 100, the box cover 200 and the box body 100 can be connected by a connection structure such as a threaded fastener, a snap button, a rotary pair, etc., or can be directly connected by a press fit without using a connection structure. together.

A recovery cavity 120 is also provided inside the box body 100, and the recovery cavity 120 can be used to recover the residue of oral food or used oral food, so as to avoid environmental pollution problems caused by random discarding. In one embodiment, the food cavity 110 and the recovery cavity 120 are separated by a partition structure 130 , that is, the food cavity 110 is not communicated with the recovery cavity 120 , so as to avoid the contamination of the food cavity 110 by the recycled material in the recovery cavity 120 . In one embodiment, as shown in FIG. 2 , the partition structure 130 may be a partition plate; in another embodiment, the surface of the partition structure 130 used to form the food cavity 110 and/or the recovery cavity 120 may be a concave-convex surface, To adjust the volume of the food cavity 110 or the storage cavity 120 .

As shown in FIG. 3 , the recovery chamber 120 also includes an opening 121 , through which recyclables can be put into the recovery chamber 120 or taken out from the recovery chamber 120 . The packaging box further includes a recovery cover 300 for closing the opening 121 , the recovery cover 300 is rotatably connected to the box body 100 , and can open or close the opening 121 when the recovery cover 300 rotates relative to the box body 100 .

See Figures 3 and 4. The box body 100 further includes a rotating pair 400 disposed inside the recovery cavity 120 . The rotating pair 400 includes a first rotating body 410 fixedly connected with the box body 100 and a second rotating body 420 fixedly connected with the recovery cover 300 . The rotating pair 400 has a rotating shaft 430, and the first rotating body 410 can rotate relative to the second rotating body 420 around the rotating shaft 430, that is, the rotatable connection between the aforementioned recovery cover 300 and the box body 100 is through the first rotating body 410 and the second rotating body 420. The rotatable connection between the swivels 420 is achieved. In the extending direction of the rotating shaft 430, the first rotating body 410 is fixed relative to the second rotating body 420, because the box body 100 and the first rotating body 410 are fixedly connected, and the recovery cover 300 and the second rotating body 420 are fixedly connected. Therefore, the relative position between the recovery cover 300 and the box body 100 is also fixed along the extending direction of the rotating shaft 430 , that is, the recovery cover 300 and the box body 100 are fixedly connected in at least one direction, thereby avoiding the recovery cover 300 The problem of being easily dropped from the box body 100 .

Generally speaking, the recovery cavity 120 is used to temporarily accommodate recyclables, and the required volume is relatively small. The present invention adopts the method of arranging the rotary pair 400 in the recovery cavity 120 , on the premise of satisfying the recovery function of the recovery cavity 120 . In this case, the connection structure between the box body 100 and the recovery cover 300 can be avoided outside the packaging box, so that the packaging box is simple and beautiful, and the volume of the packaging box can be reduced, which is convenient for people to carry. In addition, a sticker with product information drawn on the outer surface of the packaging box usually needs to be pasted, and the rotary pair 400 is arranged inside the recycling cavity 120, so that the packaging box has a relatively smooth outer surface, which is convenient for sticking the sticker, and can improve the packaging The craftsmanship of box manufacturing.

Further, the extending direction of the rotating shaft 430 is perpendicular to the plane where the opening 121 is located, that is, the opening direction of the recovery cover 130 is parallel to the plane where the opening 121 is located.

That is, in the case of non-human operation, for example, when the packaging box is placed in a pocket of clothes and carried, even if the recovery cover 300 is subjected to an uncontrollable external force (eg, frictional force of clothes), the recovery cover 300 will not be opened.

The shape of the opening 121 and the position of the rotating shaft 430 need to be designed to match, so as to realize the function of closing and opening the opening 121 . In one embodiment, the opening 121 is circular, and the circular opening 121 is not only easy to manufacture, but also generally more beautiful in visual effect. In this embodiment, the opening 121 only needs to be designed in a circular shape, and the box body 100 itself is not limited by the shape of the opening 121, and can be designed in other shapes such as cylindrical, square, and irregular shapes.

See Figure 3 and Figure 4 again. The rotating shaft 430 is eccentrically arranged relative to the opening 121 . It can be understood that when the opening 121 is circular, the opening and closing of the opening 121 can be realized only when the rotating shaft 430 is eccentrically arranged relative to the opening 121 . Specifically, the rotation axis 430 and the plane where the opening 121 is located intersect at the first intersection 122 , and there is an eccentric distance e between the first intersection 122 and the center 123 of the opening 121 . It can be understood that the larger the value of the eccentricity e is, the larger the area of the opening 121 that can be opened, but if the eccentricity e is too large, the openable area of the opening 121 and the speed at which it is opened will increase accordingly, and the items in the cavity 120 will be recovered. Easily spilled. In a preferred embodiment, the eccentricity e is 0.25-0.35 times the diameter of the opening 121 .

Referring again to FIG. 1 , the packaging box further includes a locking device 500 . The locking device 500 includes a first fastener 510 fixed on the box body 100 and a second fastener 520 fixed on the recovery cover 300 .

The thinned portion 310 is a part of the sheet-shaped recovery cover 300 , and the portion has a thinner thickness relative to the adjacent recovery cover portion. When the recovery cover 300 rotates relative to the box body 100 to the closed position of the opening 121 , the thinned portion 310 is engaged in the lock groove on the protruding portion 160 , so that the recovery cover 300 is engaged with the lock on the protruding portion 160 in the slot. The thinned portion 300 may be obtained by cutting from the blank of the recovery cover 300, or may be directly formed by injection molding. The design effectively utilizes the existing part of the recycling cover 300 without adding additional components, which not only simplifies the structure, but also makes the appearance of the packaging box simple and beautiful. In a preferred embodiment, the free end of the protruding portion 160 is flush with the bottom surface of the recycling cover 300, which can further simplify the appearance of the packaging box. It can be understood that, in another embodiment, the lock groove may be provided on the recovery cover 300 , and the lock tongue may be provided on the box body 100 .

Further, one of the first rotating body 410 and the second rotating body 420 is an inner rotating column, the other is an outer rotating column, and the inner rotating column is sleeved inside the outer rotating column. In one embodiment, the outer surface of the inner rotating column is in contact with the inner surface of the outer rotating column, so that the rotation process of the rotary pair 400 is more stable. When the box body 100 and the recovery cover 300 are injection-molded, the design of the rotating pair 400 in which the inner and outer rotating columns are matched can also improve the manufacturability of the injection-molding.

Specifically, one end of the outer rotating column is connected to the cavity wall of the recovery cavity 120 opposite to the opening 121, and extends from the connection to the direction of the opening 121; one end of the inner rotating column is connected to the recovery cover 300 for closing the opening. On the side of 121, the extension direction of the inner rotating column is parallel to the outer rotating column. It can be understood that, in another embodiment, an inner rotating column may be provided on the box body 100 , and an outer rotating column matched therewith may be provided on the recovery cover 300 .

It can be understood that with the increase of the outer diameter of the outer rotating column, the rigidity of the rotary pair 400 increases accordingly, and the rotation stability of the recovery cover 300 relative to the box body 100 increases accordingly, but at the same time, the volume of the recovery cavity 120 decreases. . In one embodiment, the outer diameter of the outer rotating column is 0.25-0.35 times the inner diameter of the recovery cavity, which can take into account the volume of the recovery cavity 120 and the rigidity of the rotary pair 400 .

In one embodiment, the inner rotating column is a hollow structure, which can save materials for manufacturing the packaging box.

Further, as shown in FIG. 4 to FIG. 6 , the inner surface of the outer rotating column is provided with a first latching protrusion 411 extending along its circumferential direction, and the outer surface of the inner rotating column is provided with a second clamping portion 411 extending along its circumferential direction. The protruding portion 421, the first engaging protruding portion 411 and the second engaging protruding portion 421 are in contact with each other, so as to prevent the inner rotating column and the outer rotating column from being separated from each other.
