The paper-plastic package box

Technical field

The utility model relates to field of product packaging, particularly relates to a kind of paper-plastic package box for each electronic product of packing (particularly notebook PC).

Background technology

Electronic products such as notebook PC, mobile phone, pick up camera are more valuable; and the aseismicity of itself and crushing resistance are relatively poor; so the time all need its protection in its transportation and storage, with prevent its because of contingent vibrations, push, fall or clash into and damage, and then cause unnecessary loss.

At present, in order to guarantee that the customer can receive intact product, be provided with foam inner liner in the packing box of each electronic product (particularly notebook PC, host computer), the interior profile of this foam inner liner and the outline of packaged product are complementary, and then play the bumper and absorbing shock effect; In addition, also place the weighting material made from foam beads, shredded paper bar or plastic inflatable bag in the space of some producer between packing box and product.Though foam and plastics are easy to process, cheap, but they are main environmental pollution things, can't recycling, and under natural environment basic non-degradable, can discharge noxious gas during burning, so use foam or plastics not to meet environmental demands in a large number.Simultaneously, adopt foam inner liner or weighting material can strengthen the volume of product packing box, thereby increase cost of product, waste resource.

The utility model content

The shortcoming of prior art in view of the above, the technical problems to be solved in the utility model are to provide the paper-plastic package box of the good and environmental protection of a kind of bumper and absorbing shock performance.

For achieving the above object, the utility model provides a kind of paper-plastic package box, comprise collet and loam cake, be provided with article putting groove in the described collet, in four sidewalls of collet, the upper limb of at least three sidewalls is outward extended with foldable flap, described flap is provided with a plurality of stepped groove that distribute along the flap length direction, bottom at described flap, the bottom land of described stepped groove forms a plurality of stepped appearance projectioies, and described stepped appearance projection comprises lower first step and higher second step, after flap turnover downwards, the sidewall at described first step and this flap place fits, and described second step is stuck in the lower edge of this flap place sidewall.

Preferably, cover the concaveconvex structure that has been provided with buffer action on described.

Preferably, cover the boss that is provided with a plurality of buffer actions on described.

Further, described article putting groove comprises host slot and is positioned at the accessory slot of host slot one side that described flap is three, lays respectively at its excess-three side of this host slot.

As mentioned above, the paper-plastic package box that the utility model relates to has following beneficial effect:

This paper-plastic package box cooperatively interacts to protect product in the article putting groove by a plurality of stepped groove on the flap and first step, second step and collet sidewall; and then play good bumper and absorbing shock effect; simultaneously; this paper-plastic package box by reclaim paper pulp, stalk paper pulp processed, bamboo pulp or cane syrup etc. not the environment-friendly materials of consumption of natural resource make; its material can be degraded fully; fundamentally meet the environmental demands that country formulates, and realized economy capable of circulation.

The specific embodiment

Below by particular specific embodiment embodiment of the present utility model is described, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification sheets.

Notice, the appended graphic structure that illustrates of this specification sheets, ratio, size etc., equal contents in order to cooperate specification sheets to disclose only, understand and reading for person skilled in the art scholar, be not in order to limit the enforceable qualifications of the utility model, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not influencing under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this specification sheets as " on ", the term of D score, " left side ", " right side ", " centre " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under no essence change technology contents, when also being considered as the enforceable category of the utility model.

The utility model provides a kind of paper-plastic package box, by reclaim paper pulp, stalk paper pulp processed, bamboo pulp or cane syrup etc. not the environment-friendly materials of consumption of natural resource make, be used for packing electronic product, particularly pack notebook PC.Extremely shown in Figure 6 as Fig. 1, this paper-plastic package box comprises collet 1 and loam cake 2, be provided with article putting groove 11 in the described collet 1, in four sidewalls of collet 1, the upper limb of at least three sidewalls is outward extended with foldable flap 3, described flap 3 is provided with a plurality of stepped groove 31 that distribute along flap 3 length directions, bottom at described flap 3, the bottom land of described stepped groove 31 forms a plurality of stepped appearance projectioies 4, described stepped appearance projection 4 comprises lower first step 41 and higher second step 42, after flap 3 turnover downwards, described first step 41 fits with the sidewall at these flap 3 places, and described second step 42 is stuck in the lower edge of these flap 3 place sidewalls.

In this paper-plastic package box, first step 41 and the second step 42 of the stepped groove 31 on the described flap 3 and formation stepped appearance projection 4 are the buffer structure of collet 1, jointly the product in the article putting groove 11 is played the bumper and absorbing shock effect, and then effectively prevent product in its transportation and storage process because of contingent bump or fall and damage, thereby guarantee that the customer receives intact product.In addition, second step 42 also supports product in the article putting groove 11 with the bottom land of article putting groove 11 jointly when playing buffer action.Simultaneously, this paper-plastic package box is made by environment-friendly materials, compliance with environmental protection requirements, and can degrade fully, the saving data has realized economy capable of circulation.In the present embodiment, described collet 1, flap 3, stepped appearance projection 4 structure that is formed in one, thus be convenient to processing and manufacturing, and reduced the overall volume of product packing box, save the energy and material, improved comprehensive utilization ratio, reduced packing of product cost and Product transport expense greatly.
