Abstract
The utility model relates to a high-strength corrugated case which mainly solves the problems that an existing corrugated case is not enough in strength and the case bottom falls off easily. The high-strength corrugated case is characterized in that the case bottom, a front side face, a rear side face, a left side face and a right side face are of an integrated type, four transverse pressing lines of the case bottom are in a circular arc shape, and the inner wall of each of the four circular-arc-shaped transverse pressing lines is provided with a polystyrene layer. The circular-arc-shaped transverse pressing lines greatly relieve stress concentration and are matched with the polystyrene layers, so that the buffering effect is obvious, and the pressing resistance and strength of the corrugated case are greatly improved.
Description
Technical field
The utility model relates to a kind of packing technique field, is specifically related to a kind of high-strength 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.Usually corrugated case comprise at the bottom of case lid, the case and all around the four sides side form, then come completed assembled by bonding or bookbinding.But such carton compression ability and intensity are all inadequate, especially divide bottom the case to be easy to come off.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of high-strength corrugated case, holds caducous problem at the bottom of mainly having solved existing corrugated case insufficient strength and case.
The technical scheme that the utility model adopts is: a kind of high-strength corrugated case, comprise at the bottom of casing, case lid and the case, described casing is square, described casing comprises leading flank, trailing flank, left surface and right flank, be integral type with leading flank, trailing flank and left surface, four faces of right flank at the bottom of the described case, and four horizontal line balls at the bottom of the case are circular-arc, and the four end compression lines in side are circular-arc; Described four circular-arc horizontal line ball inwalls are provided with one deck polystyrene layer.
Described horizontal line ball width is 10-50mm.
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, circular-arc horizontal line ball has alleviated the stress concentration phenomenon greatly, and the cooperation of polystyrene layer, and buffering effect is obvious, has greatly increased crushing resistance and the intensity of corrugated case.
Description of drawings
Fig. 1 is structural representation 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-polystyrene layer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of high-strength corrugated case, comprise at the bottom of casing 1, case lid 2 and the case 3, described casing 1 is square, described casing 1 comprises leading flank, trailing flank, left surface and right flank, at the bottom of the described case 3 with leading flank, trailing flank and left surface, four faces of right flank be integral type, and four horizontal line balls 4 at the bottom of the case are circular-arc, the four end compression lines in side are circular-arc, and described horizontal line ball 4 width are 10-50mm; Described four circular-arc horizontal line ball 4 inwalls are provided with one deck polystyrene layer 5.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 are circular-arc, greatly alleviated the phenomenon that stress is concentrated, cooperation with polystyrene layer 5, buffering effect has clearly increased crushing resistance and the intensity of corrugated case greatly.
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 intensity and the crushing resistance of this corrugated case.
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.
