Rack packaging structure carton
Technical field
The utility model relates to a kind of packaging carton, refers more particularly to a kind of high strength rack packaging structure carton.
Background technology
The rack packing chest of heat exchanger generally all is to adopt wooden case and cellular carton at present, these two kinds of chests have all played very good effect to chest the inside product, but aspect other, also have the following disadvantages: 1), since wooden case contain formaldehyde, and formaldehyde has been listed in the article scope that is prohibited from entering by a lot of developed countries, iron nail on wooden case and steel band all have electrodeposited coating in addition, therefore it causes certain pollution, very not environmental protection to environment; 2), because the wooden case material is plank, serious to lumber consumption, environmental resource is destroyed serious, not environmental protection; 3), the wooden case Heavy Weight, volume is big, carrying stores all very inconvenient, the cost of transportation height; 4), wooden case manufacturing procedure complexity, big to environmental concerns, the tooling cost height; 5), use honeycomb cardboard to substitute wooden case, intensity ratio is higher, but cost is also very high, compares than common paper-board material will exceed a lot, close prices even exceed the isostructural wooden case of same specification.
Based on the weak point of above-mentioned existing rack packing chest mode, the inventor has designed the utility model a kind of " rack packaging structure carton ".
The utility model content
The utility model at above-mentioned the deficiencies in the prior art technical matters to be solved is: a kind of not only environmental protection but also the low high strength rack packaging structure carton of cost are provided.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of rack packaging structure carton comprises that a quadrangle encloses the card division, is provided with canopy at the top of enclosing the card division, is provided with bottom in the bottom of enclosing the card division, and described canopy or bottom form by integrated corrugated board is folding.Canopy and bottom cover structure are the one-shot forming structure, are machined by hydraulic cutting presser, and top (bottom) is a double-decker after day bottom moulding, strengthens support strength, prevents to expose and break.
Described corrugated board comprises and covers body, and the two ends up and down of lid body are provided with sidepiece, and the two ends of sidepiece have extended the portion of being held, and the two ends, the left and right sides of lid body are provided with holding part, and the opposite side of holding part extends the thickening part of folding mutually with the lid body.
The described four jiaos of inboards, card division of enclosing are inserted with four paper angle protectors that are used to strengthen enclosing card division compressive strength, and this paper angle protector is made with the craft paper material.
The craft paper material that described paper angle protector thickness is 5mm is made.
Make with three hole corrugated boards the described card division of enclosing.Adopt high-intensity three hole corrugated boards, material is X7X7X7X, and the hole type is ABC hole, with this cardboard as enclosing the card division, as the composition main body of whole packing chest; Enclose the paper angle protector that the card division adds four thick craft paper materials of 5mm all around simultaneously, be used for strengthening the compressive strength of this structure.Use a canopy and bottom that entire package is sealed up and down respectively enclosing the card division then, canopy and bottom all use the X7X7X double-layer corrugated cardboard, re-use strap after installing and pack fixing on casing.Above material cardboard all is common corrugated board material, and technology is common production and processing technology.
A kind of rack packaging structure of the utility model with the beneficial effect of carton is:
1. carton is environment-friendly materials, and is recyclable, can export, little to the environmental resource influence;
2. processing technology is common carton production technology, and technical maturity is simple;
3. enclose card division, canopy and bottom and be all folding structure, very convenient in transportation, storage and the production circulation process, the transport and storage expense is low;
4. can under the prerequisite of not destroying packing, recycle outer packing box;
5. day bottom double-layer folding structural strength height is difficult for exposing, and can better protect content;
6. the entire package cost is low, and this type of cardboard box structure packing cost has only about 40% of common wooden case packing cost, cost-cutting effectively.

The specific embodiment
Referring to figs. 1 through Fig. 6, the utility model is to implement like this:
A kind of rack packaging structure carton, comprise that a quadrangle encloses card division (10), be provided with canopy (20) at the top of enclosing card division (10), be provided with bottom (30) in the bottom of enclosing card division (10), canopy (20) and bottom (30) form by integrated corrugated board (40) is folding.Corrugated board (40) comprises and covers body (41), the two ends up and down of lid body (41) are provided with sidepiece (42), the two ends of sidepiece (42) have extended the portion of being held (43), the two ends, the left and right sides of lid body (41) are provided with holding part (44), and the opposite side of holding part (44) extends the thickening part (45) folded mutually with lid body (41).Enclose (10) four jiaos of inboards, card division and be inserted with four paper angle protectors (50) that are used to strengthen enclosing card division (10) compressive strength, this paper angle protector (50) is made with the craft paper material.
In the present embodiment, paper angle protector (50) is that the craft paper material of 5mm is made with thickness, encloses card division (10) and makes with three hole corrugated boards.
The above, only be of the preferred embodiment of a kind of high strength rack of the utility model packaging structure with carton, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model above any trickle modification, equivalent variations and modification that embodiment did.
