Abstract
The utility model relates to a heavy corrugated case. The heavy corrugated case mainly solves the problem that heavy objects can easily crack when being packaged in the prior corrugated cases. The heavy corrugated case is characterized in that a case bottom is integrated with the front surface, the rear surface, the left surface and the right surface, and four transverse pressing lines and four longitudinal pressing lines at the bottom are in the shapes of circular arcs; buffering layers are arranged on four corners of the inner side of the bottom of the case; PP layers adhere to the inner wall of the case body and the inner wall of a case cover. The buffering layers on the four corners of the inner side of the bottom and the PP layers adhering to the inner walls greatly increase strength of the corrugated case body, and therefore the heavy objects can not easily crack when being packaged in the heavy corrugated case.
Description
Technical field
The utility model relates to a kind of packing technique field, is specifically related to a kind of heavy corrugated case.
Background technology
Carton is widely used in daily life and field of industrial production.In order to improve the mechanical strength of carton, people have carried out long-term exploration, have proposed various solutions.For example, some people adopts intensity is higher or thickness is thicker paper as raw material, and obviously, this scheme exists the high defective of cost.
Fluting board is the plate object that the corrugation of the waveform that forms by sheet lining with by corrugated roller processing is bonded, and generally is divided into single wall corrugated board and double-layer corrugated cardboard two classes.Be pressed in process of production the corrugation shape, making after the corrugated board it will provide cardboard elasticity, parallel intensity and affect the performance such as vertical compression intensity.Fluting board, paper is smooth, and it is consistent that thickness is wanted, and the paper defects such as fold, breach and hole can not be arranged, otherwise increase the broken end fault of production process, affects product design.Corrugated board is made corrugated case through cross cutting, impression, nail case or glutinous case.Corrugated case is a kind of most widely used packing articles, and consumption is first of the various packing articles always.
In the time of corrugated case packing weight, usually can break because casing bears incessantly weight.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of heavy corrugated case, the problem of easily having broken when mainly having solved existing corrugated case packing weight.
The technical scheme that the utility model adopts is: a kind of heavy corrugated case, comprise at the bottom of casing, case lid and the case, described casing is square, comprise front, rear, left and right, four sides, be integral type with forward and backward and left and right four faces at the bottom of the described case, and four end compression lines of four horizontal line balls of bottom and side are circular-arc; Four bights of described bottom half inboard are provided with cushion layer; All be attached with the PP layer on the inwall of described casing and case lid.
Described cushion layer is the polystyrene material.
Described cushion layer has two square edges, and described square edge leans on mutually with two sides of casing respectively.
The casing at described case lid and forward and backward and left and right four sides is bonding by glue.
Be 5 layers or 7 layers of corrugated board at the bottom of described casing and the case.
The beneficial effects of the utility model are: owing to take technique scheme, the PP layer that adheres on the cushion layer at place, four bights of bottom inside and the inwall has all increased the intensity of corrugation casing greatly, makes when the packing weight to be not easy to break.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the figure that partly cuts open of the present utility model.
1-casing among the figure, the 2-case lid, at the bottom of the 3-case, the horizontal line ball of 4-, 5-end compression line, 6-cushion layer, 7-PP layer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Such as Fig. 1 in conjunction with shown in Figure 2, a kind of heavy corrugated case, comprise at the bottom of casing 1, case lid 2 and the case 3, described casing 1 is square, comprise front, rear, left and right, four sides, at the bottom of the described case 3 with forward and backward and left and right four faces be integral type, and four end compression lines 5 of four horizontal line balls 4 of bottom and side are circular-arc; Four bights of described casing 1 bottom inside are provided with cushion layer 6; All be attached with PP layer 7 on the inwall of described casing 1 and case lid 2.At the bottom of the case 3 with casing 1 formula that is connected as a single entity, avoided because the phenomenon that glue is bonding or bookbinding can cracking occur and come off under the effect of weight afterwards, and four horizontal line balls 4 and four end compression lines 5 are circular-arc, greatly alleviated the phenomenon that stress is concentrated, cooperate four bights to locate the cushion layer 6 that is provided with and the PP layer 7 that is attached to inwall, greatly increased the intensity of this corrugation case, made when the packing weight to be not easy to break.
Described cushion layer 6 is the polystyrene material.Cushion layer 6 buffering effects of polystyrene material are more obvious, and very economical.
Described cushion layer 6 has two square edges, and described square edge leans on mutually with two sides of casing 1 respectively.Through check, the buffering effect of this kind cushion layer 6 is best.
Described case lid 2 is bonding by glue with the casing 1 at forward and backward and left and right four sides.Because do not have the effect of weight between case lid 2 and the casing 1, adopt glue bonding not only convenient but also economical.
3 is 5 layers or 7 layers of corrugated board at the bottom of described casing 1 and the case.A nearly step has strengthened the intensity of this corrugated case, in order to support the object that more increases the weight of.
Every technical personnel notice: although the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
