A kind of heavier-duty lock carton

Technical field

The utility model relates to the package packing supplies field, relates in particular to a kind of heavier-duty lock carton.

Background technology

In daily life, carton is indispensable packing, mainly be because carton to have price low, in light weight; And with back plurality of advantages such as recyclable, and along with social development, environmental protection, energy-saving and emission-reduction etc. becomes mainstream of society; Excessive packaging, food security receive public's attention day by day, traditional packing, for example plastics, five metals etc.; All higher and reclaim difficulty because of cost of manufacture, and be eliminated at last, and replaced by the recyclable paper products that utilize again.

At present, various lock cartons and packing box are most to be made for homogenous material, perhaps adopts a large amount of cardboards and board fiber board as load-bearing material; Not only do not meet the theory of low-carbon environment-friendly, also can increase extra Master Cost, the performance of buffering is also relatively poor in addition; Out of reach is to the protection requirement of product; Be easy under the effect of extraneous application force, carton destroys, even injures the article of placing in the carton.

The utility model content

The purpose of the utility model is to address the above problem, and a kind of heavier-duty lock carton is provided, and it has simple in structure, with low cost, environmental protection and public nuisance free, good airproof performance and the firm advantage of box body.

The purpose of the utility model is to realize through following technical scheme:

A kind of heavier-duty lock carton comprises foldable formed loam cake and lower cover, in the said loam cake cap packing is set, and in the said lower cover cap packing is set down.

Further; The size of said loam cake is greater than the size of last cap packing; So that the said cap packing of going up is contained in said loam cake inboard, the size of said lower cover is greater than the size of following cap packing, so that said cap packing down is contained in said lower cover inboard; And the said size that goes up the size of cap packing greater than lower cover, so that said loam cake and go up cap packing integral body and be buckled in the said lower cover and the periphery of cap packing down.

Further, said loam cake is by the folding and spicing moulding.

Further, said lower cover is by the folding and spicing moulding.

Further, saidly go up cap packing, around the outside of cap packing and bottom all is provided with sticky bit down, and lining cement is set, equal bonding forming between said loam cake and the last cap packing, between said lower cover and the following cap packing at said sticky bit.

Preferably, said loam cake, lower cover all adopt PVC material or art post paperboard or art paper to process.

Preferably, said upward cap packing, following cap packing all adopt corrugated board or chipboard to process.

Preferably, said lining cement is double faced adhesive tape or aqueous, environmental protective glue.

Preferably, said upward cap packing, following cap packing all adopt the E corrugated board to process.

Preferably, said go up cap packing, down cap packing to adopt thickness be that the chipboard of 2.5mm is processed.

The beneficial effect of the utility model is: through cap packing and following cap packing are set, can increase the firmness of carton in the upper and lower cover of carton, improve the buffer capacity of carton, can effectively play the purpose of its internal product of protection; The equal folding and spicing moulding of upper and lower cover; The upper and lower cover liner all is bonded in the upper and lower cover inboard through lining cement; And the lining cement that uses adopts double faced adhesive tape or aqueous, environmental protective glue, can reduce the manufacturing cost of carton, and pollution-free to the product of splendid attire in the carton; The contrast prior art, that this lock carton has is simple in structure, with low cost, environmental protection and public nuisance free, good airproof performance and the firm advantage of box body.
