Abstract

The utility model discloses a packaging box comprising a box cover and a box base, wherein the box cover is connected with one end of the box base. The packaging box is characterized in that the packaging box further comprises a first set of snap-fit structures located at four corers of the box cover and the box base, and the snap-fit structures are formed by arc grooves and arc flanges on the lateral walls at the four corners of the box cover and the box base. Compared with the ultrasonic vacuum forming technique generally used in the market, the packaging box is convenient to use and avoids the procedure of vacuum forming, thereby simplifying the fabrication procedures and processes, and contributing to quality promotion.

Description

A kind of packing box

Technical field

The utility model relates to a kind of packing box, especially a kind of stationery packing box.

Background technology

Traditional pen core packing box usually adopts the wrapping plate of two plastic materials, when encapsulation or adopt the clasp machine encapsulation, perhaps adopts super sonic plastic uptake technology, and two pieces of wrapping plates are encapsulated.For the pen core individual packaging, owing to can adopt destructive mode to take out pen core, it is better suited therefore adopting above-mentioned dual mode in this case.And change the situation of some pen core groups for needs, and in case packing box destroys, promptly can bring inconvenience in the situation of placing stand-by pen core, cause and use inconvenience.In the occasion that at present more and more pen cores are changed, this defective is more and more outstanding.

Summary of the invention

At above-mentioned situation, the utility model has improved traditional packing box structure, adopts the movable button bit architecture to make the folding of packing box more convenient.

In order to realize the foregoing invention purpose, the utility model has adopted a kind of packing box, comprise lid and cassette holder, one end of described lid and cassette holder links to each other, it is characterized in that, described packing box further comprises: first group of buckle structure, be positioned at the corner location of described lid and cassette holder, and combine by arc groove and curved flanges on the corner location place sidewall of described lid and cassette holder.

Reasonablely be, described curved flanges is positioned on the outward extending lateral margin of described cassette holder sidewall, and described arc groove is positioned on the sidewall that described lid extends internally.

Reasonable is that described packing box further comprises: second group of buckle structure, form by several flanges and the groove of the square edge sidewall that is separately positioned on box body and cassette holder.

Reasonablely be, the quantity of described arc groove and curved flanges is consistent, and the quantity of described flange and groove is identical.

Reasonable is that described flange and groove are strip.

Reasonable is that the material of described packing box is plastics.

Adopt packing box of the present utility model, more easy to use than the technology of the super sonic plastic uptake that generally adopts on the market, and omitted the plastic uptake flow process, thus simplified the technological process of production, help the lifting of quality.

Description of drawings

Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.

Fig. 1 is an opening structure scheme drawing of the present utility model;

Fig. 2 is a combinatorial construction scheme drawing of the present utility model;

Fig. 3 is the local enlarged diagram of A portion among Fig. 1;

Fig. 4 is the local enlarged diagram of B portion among Fig. 1.

The specific embodiment

See also shown in Figure 1ly, packing box of the present utility model comprises lid 10 and cassette holder 11, is provided with some grooves in the described cassette holder 11 and is used to put pen core, and an end of lid 10 and cassette holder 11 links to each other.

Corner location at lid 10 and cassette holder 11, be provided with first group of buckle structure, with A among Fig. 1 and B position is example, Fig. 3 has provided the local structure for amplifying of A, as can be seen, cassette holder 11 has certain depth, and its sidewall 110 is perpendicular to the bottom and the formation lateral margin 111 that stretches out, at the angle position of this lateral margin 111, be formed with certain thickness inside curved flanges 112.

Lid 10 is made up of lid 100 and sidewall 101, and sidewall 101 is perpendicular to lid 100 and extend downwardly into certain altitude and extend to form lateral margin 103 laterally, at the angle position of sidewall 101, forms certain depth and inside arc groove 102.

The position of above-mentioned curved flanges 112 and arc groove 102 quite and thickness and the degree of depth roughly the same, therefore four buckle structures of four corners cooperatively interact, and realize movable folding.

In order to realize folding better, second group of buckle structure of the utility model packing box is arranged on the box body middle part, promptly on the sidewall 110 of cassette holder 11, be provided with several flanges 1101 and 1102 (diagram has only provided two), on the sidewall 101 of lid 10, be provided with

several grooves

1011 and 1012, the shape of this flange and groove roughly is a strip, and the position cooperatively interacts.

When lid 10 of closing said structure and cassette holder 11, in first group of buckle structure, several side wall ledge in the curved flanges 112 of four corners and the arc groove 102 mutual buckles, second group of buckle structure and groove be buckle mutually also, forms more stable full encirclement enclosed construction thus.

Because the utility model has been taked the mode of similar movable button bit, the technology of comparing the super sonic plastic uptake that generally adopts on the market is more easy to use, and has omitted the plastic uptake flow process, thereby has simplified the technological process of production, helps the lifting of quality.

More than all embodiment only for the explanation the utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.

Claims
