Description

Technical Field

[0001] The utility model belongs to the technical field of packaging, and particularly relates to a paper box capable of preventing the bottom from getting wet. Background Art

[0002] Carton is a kind of tool used for packaging various items. It is widely used in the current society. It is mainly made of paper products. According to the different materials, it can be divided into corrugated boxes and single-layer cardboard boxes, etc., and different specifications can be designed according to actual needs to meet the actual use. The existing cartons still have certain defects in the actual use process:

[0003] Since the existing cartons are mainly made of paper products, when in use, the cartons are in direct contact with the ground. When there are water stains on the ground, the carton is easily damaged by moisture after contact with water, thereby affecting the normal use of the carton and even causing the goods packaged inside to get damp. The utility model patent with publication number CN220391936U discloses a carton that prevents the bottom from getting damp, which solves the above problems, but its structure is complex: it includes a protective pad, a box cover, a sealing pad, a handle, a waterproof pallet, a moisture-proof plate, an elastic rubber ring, a top plate, an inner support plate, a reinforcing plate, a bottom plate, a connecting rod, a side plate, a first anti-slip pad, a positioning bolt, a splint and other structures. It is well known that the outer packaging carton is only used as a temporary external packaging and is generally discarded after use. If so many components are used to manufacture an outer packaging carton only to achieve its moisture-proof function, it will take a lot of time to assemble the carton. For manufacturers, the packaging cost is too expensive and a lot of resources are wasted. Therefore, the technology shown in the above-mentioned comparative documents is less practical due to cost factors. Utility Model Content

[0004] The utility model aims to provide a paper box with a bottom moisture-proof function, so as to solve the technical problems of the above-mentioned background technology in that the structure is complex and the production cost is too high when the background technology is implemented.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A cardboard box to prevent the bottom from getting wet, comprising: a box body; the box body is a square tube structure opened at the top and the bottom, the front and rear side walls of the box body extend in the upward and downward directions to generate two groups of positive flaps, the left and right side walls of the box body extend in the upward and downward directions to generate two groups of side flaps, the four groups of box bodies are folded 90 degrees toward the center of the box body, and then the four groups of positive flaps are folded 90 degrees toward the center of the box body to cover the side flaps on the upper and lower sides; a foam pad is provided at the bottom of the box body, the cross-sectional outer contour of the foam pad is consistent with the cross-sectional outer contour of the box body, and the lower surface of the foam pad is provided with supporting cones distributed at equal intervals.

[0007] Furthermore, because there are two groups of positive flaps at the bottom of the box, in order to increase the tightness of the gluing, a double-sided rubber ring with a ring structure is attached to the lower surface of each group of positive flaps under the box. The cross-sectional outer contour of the double-sided rubber ring is consistent with the cross-sectional outer contour of the positive flap, and the foam pad is glued to the two groups of positive flaps under the box using two groups of double-sided rubber rings.

[0008] Furthermore, in order to reduce the contact area between the carton and the wet surface to reduce moisture intrusion, the support cone is a conical structure that is wide at the top and narrow at the bottom.

[0009] Furthermore, in order to ensure that the cartons and the goods inside them can maintain moisture-proof performance for a longer period of time when the cartons are stacked for a long time, the foam pad is provided with a plurality of groups of recessed grooves inside the two groups of double-sided rubber rings to form an embedded warehouse, and the foam pad is equipped with a desiccant bag built into the embedded warehouse to further reduce moisture at the bottom of the carton.

[0010] Furthermore, in order to adaptively select the number of desiccant packages according to the actual storage time to reduce the waste of desiccant packages, one or more of the embedded compartments on the foam pad are equipped with desiccant packages or all the embedded compartments are not equipped with desiccant packages.

[0011] Furthermore, in order to prevent water vapor from seeping into the gap between the two groups of positive flaps under the box body, the gap between the two groups of positive flaps under the box body is a flap gap, and a strip of fillet structure is provided on the upper surface of the foam pad between the two groups of double-sided rubber rings. The width of the fillet is greater than the width of the flap gap, and the fillet is embedded in the flap gap with an interference fit.

[0012] Furthermore, in order to increase the sealing performance of the fillet, the fillet is made of a material with stronger elasticity than the foam pad, so the fillet and the foam pad need to be designed as a combined structure: a wide body structure with a width greater than that of the fillet body is provided under the fillet, and an embedded groove for accommodating the wide body structure is provided on the foam pad, and the fillet is embedded and fixed in the embedded groove using the wide body structure below it.

[0013] Furthermore, in order to facilitate those who do not understand the principle of the present invention to more quickly identify the front and back of the carton, the side wall of the box is provided with a marking symbol for marking the side of the box away from the foam pad to be placed upward.

[0014] In summary, the utility model has the following beneficial effects:

[0015] ①Simple structure and low cost: The main structure of this product is a carton plus a foam pad and a supporting cone. The cost of the carton and foam are relatively low, and the combination of the two adopts the simplest gluing method, and the assembly is also relatively simple. Therefore, with the support of low material cost and low assembly cost, the production cost of the moisture-proof carton is controlled.

[0016] ② Longer moisture-proof time: This product uses desiccant to assist in moisture-proofing. When water vapor still reaches the bottom of the carton, the moisture will be absorbed by the desiccant bag in the embedded bin, further increasing the moisture-proof ability of the bottom of the carton of the utility model.

[0028] Because there are two groups of positive flaps 2 at the bottom of the box body 1, in order to increase the tightness of the gluing, a double-sided rubber ring 5 with a ring structure is attached to the lower surface of each group of positive flaps 2 under the box body 1. The cross-sectional outer contour of the double-sided rubber ring 5 is consistent with the cross-sectional outer contour of the positive flap 2, and the foam pad 4 is glued to the two groups of positive flaps 2 under the box body 1 using two groups of double-sided rubber rings 5.

[0029] The support cone 12 is a conical structure that is wide at the top and narrow at the bottom. The support cone 12 and the foam pad 4 are an integrated structure.

[0030] The foam pad 4 is provided with a plurality of recessed grooves inside the two groups of double-sided rubber rings 5 ​​to form an embedded bin 6. The foam pad 4 is provided with a desiccant bag 10 built in the embedded bin 6 to further reduce moisture on the bottom of the carton.

[0031] One or more of the embedded compartments 6 on the foam pad 4 is provided with a desiccant bag 10 or all of the embedded compartments 6 are not provided with a desiccant bag 10 .

[0032] The gap between the two groups of positive flaps 2 below the box body 1 is a flap gap 9. A strip 8 with a strip structure is provided on the upper surface of the foam pad 4 between the two groups of double-sided rubber rings 5. The width of the strip 8 is greater than the width of the flap gap 9. The strip 8 is embedded in the flap gap 9 in an interference fit manner.
