Further, the inserted link is arranged at the position of the bottom bulge of the upper cover.

Further, the outside diameter of one end of the inserted rod is smaller than that of the other end of the inserted rod.

Further, the protruding portion is provided with at least one slot into which the corresponding insert rod is inserted.

Further, a flannelette layer which simultaneously covers the support rods is adhered to the opening of the top of the bottom box.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the convex part supported at the bottom of the upper cover is added on the outer side surface of the bottom box along with the combination of the bottom box and the upper cover, and the repeated concave-convex contact surface is formed, so that the contact surface can disperse the downward pressure of the connection of the bottom box and the upper cover, the contact surface also utilizes the inserted link to fix the contact position of the bottom box and the upper cover, the support rod with the support effect is added on the periphery of the inside, the structure inside the packaging box is reinforced, the deformation of the packaging box is prevented, the whole structure is simple, and the practicability is strong.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 4, the present utility model provides a paper package comprising a bottom case 1 with an open top and an upper cover 2 mounted at the opening of the bottom case 1, wherein the top of the bottom case 1 is tightly slid against the inner wall of the upper cover 2 to form a sealed inner cavity, which is the space for containing articles in the package, when the bottom case 1 is combined with the upper cover 2, the top of the bottom case 1 needs to slide to the top position inside the upper cover 2, so that no gap is left between the bottom case 1 and the upper cover 2 by close contact, and the inner side of the upper cover 2 is supported by the bottom case 1, so that the package will not shake or even deform.

The bottom box 1 bottom lateral surface is equipped with outside bellying 3, bellying 3 top and upper cover 2 bottom contact form repeatedly unsmooth contact surface 4, this bellying 3 encircle the bottom box 1 all around and have adopted the structure with the integrated into one piece of bottom box 1, bellying 3 are used for connecting and play certain supporting effect to upper cover 2 at upper cover 2 bottom, have formed repeatedly unsmooth contact surface 4 between the two, and vertically be the incline limit in addition, have effectively dispersed the dynamics that upper cover 2 pushed down, when upper cover 2 pushes down at bottom box 1 surface, wholly be difficult for warping.

The bottom of the upper cover 2 is also provided with at least one inserted link 5 inserted into the protruding part 3 through the contact surface 4, the inserted links 5 are distributed on each side surface of the upper cover 2, and are mainly used for ensuring that the downward protruding position of the upper cover 2 can be always fixed on the contact surface 4 contacted with the bottom box 1, so that the upper cover 2 and the bottom box 1 are always kept in a combined state, the structure of internal connection is reinforced, at the moment, the distributed position of the inserted link 5 is located at the protruding position of the bottom of the upper cover 2, however, the protruding part 3 is provided with a slot 7 inserted into the corresponding inserted link 5 at the concave position, and meanwhile, in order to make the inserted link 5 be quickly inserted into the slot 7, the external diameter of the inserted link 5 inserted into one end is smaller.

The support rods 6 for supporting the top and the bottom are embedded into the four corners of the bottom box 1, the support rods 6 for connecting the top and the bottom of the bottom box 1 are additionally arranged at the four corners of the inner cavity, the inner structure can be reinforced to prevent deformation, and the support of the bottom box 1 to the upper cover 2 is reinforced.

The flannelette layer 8 that covers bracing piece 6 simultaneously is glued to end box 1 open-top department, and flannelette layer 8 possesses certain elasticity, can reduce the friction between upper cover 2 and the end box 1, has avoided the wearing and tearing that cause because of the friction.

Compared with the prior art, this technical scheme combines with upper cover 2 along with end box 1, has increased the bellying 3 that supports 2 bottoms at end box 1 lateral surface and has formed repeatedly unsmooth contact surface 4, and this contact surface 4 can disperse the downforce that both are connected, and contact surface 4 has also utilized the fixed position of both contacts of inserted bar 5, and inside still increases bracing piece 6 that play the supporting effect all around, has consolidated the inside structure of packing carton, prevents that the packing carton from warping.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
