Abstract
本实用新型涉及一种高强度瓦楞纸箱。主要解决了现有的瓦楞纸箱强度不够以及箱底容易脱落的问题。其特征在于：所述的箱底与前侧面、后侧面以及左侧面、右侧面四个面为一体式，且箱底的四条横压线为圆弧状；所述的四条圆弧状横压线内壁上设有一层聚苯乙烯层。圆弧状的横压线大大减轻了应力集中现象，和聚苯乙烯层的配合，缓冲效果明显，大大增加了瓦楞纸箱的抗压性以及强度。
The utility model relates to a high-strength corrugated paper box. The invention mainly solves the problems that the strength of the existing corrugated cardboard box is insufficient and the bottom of the box is easy to fall off. It is characterized in that: the bottom of the box is integrated with the four sides of the front side, the rear side, the left side and the right side, and the four horizontal pressure lines on the bottom of the box are arc-shaped; the four arc-shaped horizontal pressure lines A polystyrene layer is provided on the inner wall of the wire. The arc-shaped horizontal pressure line greatly reduces the stress concentration phenomenon, and cooperates with the polystyrene layer to have an obvious cushioning effect, which greatly increases the compression resistance and strength of the corrugated box.
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.
