Abstract

The present disclosure relates to a packaging box, a device and method for detecting damage, a detection apparatus, and a storage medium, and belongs to the field of packaging technologies. The packaging box includes a plurality of packaging cardboards that are combined into the packaging box, wherein at least one packaging cardboard of the plurality of packaging cardboards includes: a surface paper; a backing paper; at least one layer of a core paper; and at least one external force detecting member, wherein the at least one layer of the core paper is disposed between the surface paper and the backing paper, and wherein the at least one external force detecting member is configured to measure a strength value of an external force when the packaging cardboard is subjected to the external force.

First claim

What is claimed is:

1. A packaging box, comprising:
a plurality of packaging cardboards that are combined into the packaging box,
wherein at least one packaging cardboard of the plurality of packaging cardboards comprises:
a surface paper;
a backing paper;
at least one layer of a core paper; and
at least one external force detecting member,

wherein the at least one layer of the core paper is disposed between the surface paper and the backing paper,
the at least one external force detecting member is configured to measure a strength value of an external force when the packaging cardboard is subjected to the external force,
the at least one external force detecting member comprises a plurality of liquid layers that layered between the surface paper and the backing paper, and
each liquid layer in the plurality of liquid layers is provided with a liquid of one color different from that of other liquid layers, and has a bearing strength different from that of other liquid layers, and the plurality of liquid layers are arranged in an order of gradually increasing bearing strength from the surface paper to the backing paper; and
the plurality of liquid layers are configured to indicate the strength value of the external force through a box color presented on the packaging cardboard by a liquid that flows out from a broken liquid layer when the packaging cardboard is subjected to the external force, and to indicate a force-receiving area of the packaging cardboard through an area presenting the box color on the packaging paperboard.

2. The packaging box according to claim 1 , wherein, when the packaging cardboard comprises only one layer of the core paper, the plurality of liquid layers comprise a first liquid layer and a second liquid layer, and the first liquid layer is disposed between the surface paper and the one layer of core paper, and the second liquid layer is disposed between the one layer of core paper and the backing paper, and
wherein, when the packaging cardboard comprises multiple layers of the core paper, the multiple layers of the core paper are sequentially disposed between the surface paper and the backing paper, and the plurality of liquid layers are disposed between the multiple layers of the core paper.

3. The packaging box according to claim 1 , wherein, when the packaging cardboard comprises only one layer of the core paper, the plurality of liquid layers comprise one liquid layer, and the liquid layer is disposed between the one layer of the core paper and one of the surface paper and the backing paper, and
wherein, when the packaging cardboard comprises multiple layers of the core paper, the multiple layers of the core paper are sequentially disposed between the surface paper and the backing paper, and the plurality of liquid layers are disposed between the multiple layers of core paper.

4. The packaging box according to claim 1 , wherein each of the plurality of liquid layers comprises a sealed bag that is composed of a plurality of sealing lattices, wherein each of the plurality of sealing lattices includes liquid, and each of the plurality of sealing lattices is separated from other ones of the plurality of sealing lattices.

5. The packaging box according to claim 1 , wherein the at least one layer of the core paper comprises at least one layer of corrugated core paper, and the at least one layer of the corrugated core paper is one of A corrugated paper, B corrugated paper, C corrugated paper, and E corrugated paper.

6. A packaging box according to claim 1 , wherein an inner side of the backing paper is covered with a protective film for separating the backing paper and articles in the packaging box.

7. The packaging box according to claim 1 , wherein the backing paper is closer to an interior of the box than the surface paper;
the at least one layer of the core paper comprises multiple layers of corrugated core paper, at least two layers of the corrugated core paper in the multiple layers of corrugated core paper are of different types, wherein the type indicates a corrugated height and a buffering effect, and the corrugated height is proportional to the buffering, effect; the multiple layers of corrugated core paper are arranged in an order of gradually increasing the corrugating height from the surface paper to the backing paper; and
the plurality of liquid layers are layered between e surface paper and an adjacent layer of corrugated core paper, and/or, between any two adjacent layers of corrugated core paper, and/or, between the hacking paper and an adjacent layer of corrugated core paper.

8. A method for determining damage of a packaging cardboard of a packaging box, the method comprising: determining external force information presented by at least one external force detecting member in the packaging cardboard based on an external force when the packaging cardboard is subjected to the external force; and determining a strength value of the external force based on the external force information presented by the at least one external force detecting member, wherein a plurality of packaging cardboards are combined into the packaging box, at least one packaging cardboard of the plurality of packaging cardboards comprises: a surface paper; a backing paper; at least one layer of a core paper; and at least one external force detecting member, the at least one layer of the core paper is disposed between the surface paper and the backing paper, the at least one external force detecting member is configured to measure a strength value of an external force when the packaging cardboard is subjected to the external force, the at least one external force detecting member comprises a plurality of liquid layers that are layered between the surface paper and the backing paper, and each liquid layer in the plurality of liquid layers is provided with a liquid of one color different from that of other liquid layers, and has a bearing strength different from that of other liquid layers, and the plurality of liquid layers are arranged in an order of gradually increasing bearing strength from the surface paper to the backing paper; and the plurality of liquid layers are configured to indicate the strength value of the external force through a box color presented on the packaging cardboard by a liquid that flows out from a broken liquid layer when the packaging cardboard is subjected to the external force, and to indicate a force-receiving area of the packaging cardboard through an area presenting the box color on the packaging paperboard cardboard.

9. The method according to claim 8 , wherein the external force information is a box color presented on the packaging cardboard by a damaged liquid layer of the plurality of liquid layers, and
wherein determining the strength value of the external force comprises determining the strength value of the external force based on the box color.

10. The method according to claim 9 , wherein determining the strength value of the external force based on the box color comprises:
obtaining, according to the box color a bearing strength value to which the box color corresponds from a corresponding relationship between the box color and the bearing strength value; and
designating the bearing strength value to which the box color corresponds as the strength value of the external force.

11. The method according to claim 8 , wherein after determining the strength value of the external force based on the external force information presented by the at least one external force detecting member, the method further comprises:
generating a detection report according to the strength value of the external force, wherein the detection report comprises cardboard
