Abstract

The utility model relates to an edge protector device for a package cardboard box. The utility model comprises fixed slots and edge protectors of certain compression strength, the fixed slots are fixed on inner sides of four edges of a cardboard box, and the edge protectors are inserted in the fixed slots, wherein, an edge protector slot arranged on the inner side of each box edge is divided into an upper segment and a lower segment which are arranged correspondingly; outside diameters and inside diameters of the edge protector slots are mutually matched with outside diameters and inside diameters of the edge protectors, and each cross section can be circular or polygonal. As the edge protector device and the cardboard box can be respectively put into standard production, the fixed slots on the cardboard box can be integrally formed with the cardboard box, and the edge protector device can be specially installed on the cardboard box according to the bearing and loading condition of articles to pack, so as to enhance compressive strength; therefore, the utility model is not only convenient in use, but also can save packing cost.

Description

The edge protector device of Packaging Box

The utility model relates to transportation package holds, particularly a kind of edge protector device that is used to improve the compressive strength of carton or coaming plate.

Goods transport generally need use wooden case, carton, plastic box etc. as packing container, but they all have weak point separately, with regard to wooden case, at first, the weight of itself is bigger, at some is the valuation freight department of unit with weight, its cost of transportation is comparatively expensive, and the wooden case that does not secondly carry out special processing has many disease and pests, so generally at food and when being subject to the material packing of disease and pest invasion and attack or outlet, must go out in advance harm reason of cootle can make cost increase so again.For China, timber resources is original just not abundant, and is constantly reducing, so for environmental protection requirement, become the trend and direction of development as packing container with other material replacing wood.

Adopting corrugated case to replace wooden case at present is common a kind of form, but when this type of carton and interior loading thing can not together support, its compressive strength is lower than wooden case, when transporting large numbers of items, particularly when interior loading thing is not enough or when bigger bulk goods of weight or profile fitfull product, carton holds more be can't stand, the more difficult transportation burden of finishing, therefore will be on the basis of original carton, by the rational structure transformation, increase its compressive strength, just can make carton replace wooden case to become possibility.

In order to solve the lower problem of corrugated case bearing pressure, the someone proposed several raising pressure-bearing schemes in the past, as do the square coaming plate along inwall in carton; In carton, do the octagon coaming plate; Outside carton, do the triangle edge protector; Do carton with the honeycomb fluting board, but these schemes, the consumption material that has is more, and the goods spatial accommodation loss that has is big, and compressive strength improve little, though have can improve compressive strength, install and use inconvenience, production facilities has high input, the cost height, and standardization level is poor.

The purpose of this utility model provides and a kind ofly can improve Packaging Box compressive strength, but standardized production, easy disassembly, lower-cost Packaging Box edge protector device.

The utility model is achieved in that a kind of edge protector device of Packaging Box, comprises the hold down groove that is fixed in carton four rib inboards and insert in the interior edge protector with certain compressive strength of hold down groove that the edge protecting groove of each case rib inboard divides upper and lower two sections corresponding settings; The interior external diameter of edge protecting groove and edge protector mates mutually, and cross-sectional plane can be circle or polygon.The edge protector hold down groove can form to extruding the simple folded, glued of line ball along stupefied with watt rib paper, and edge protector can be with timber, plastics, also available other has the material of certain compressive strength.

The utility model has the advantages that, because the edge protector device can be distinguished standardized production with carton, the hold down groove on the carton wherein, also can be one-body molded with carton, so carton visual connection with wrapping of piece pressure-bearing situation and the edge protector device is installed temporarily increasing compressive resistance is not only easy to use but also can save packing cost.

The following drawings and embodiment will be described further the utility model architectural feature:

Fig. 1 is the carton block diagram that has the edge protector hold down groove.

Fig. 2 is the utility model edge protector plane outspread drawing.

Fig. 3 is the carton plane outspread drawing that has the edge protector hold down groove.

Nomenclature among the figure:

A ... applying glue face C ... the carton face

B ... corrugation direction D ... the carton face

1 ... edge protector E ... the carton face

2 ... the carton or the coaming plate F that have hold down groove ... the carton face

3 ... hold down groove

Embodiment: edge protector is made of fluting board, and as shown in Figure 2, dotted line is represented line ball among the figure to the line ball that extrudes some preset space lengths along stupefied with fluting board, pusher wire winding and bonding in turn again, and cross sectional shape can circle or polygon; Other has the material of certain compressive strength the also available timber of edge protector, plastics etc.Hold down groove be shaped (shown in Figure 5) along the EF face along line ball (dotted line) roll over inwards, C, D are towards outer folding, just take advantage of a situation and roll over inwards along line ball in the two sides, the hold down groove (see figure 6) hold down groove of formation square sectional is generally with eight (every rib upper and lower two).As shown in Figure 7, during use, earlier hold down groove is bonded in the inboard of upright four ribs of carton, and edge protector inserted in the hold down groove gets final product.

Claims

1, a kind of edge protector device of Packaging Box is characterized in that: comprise the hold down groove that is fixed in carton four rib inboards and insert in the interior edge protector with certain compressive strength of hold down groove.

2, edge protector device according to claim 1 is characterized in that: the hold down groove of each case rib inboard, divide upper and lower two sections corresponding settings, and the interior external diameter of hold down groove and edge protector mates mutually, and cross-sectional plane can be circle or polygon.
