Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1:
a coating paper box structure for hot filling of liquid is disclosed, referring to fig. 1, comprising a square box body 1 made of corrugated paper, wherein the box body 1 is provided with an inner cavity 11 for placing articles, and a box cover 12 is arranged at the opening of the inner cavity 11. The box cover 12 is square, one side of the box cover 12 and one side of the cavity opening of the inner cavity 11 are integrally formed, and the size of the box cover 12 is matched with the size of the cavity opening. When the carton is packaged, the box cover 12 is covered on the box body 1, and the box cover 12 can be sealed on the box body 1 by using an adhesive tape.
Referring to fig. 2 and 3, the inner side walls of the carton are provided with waterproof layers 2, and the waterproof layers 2 are PP films. The box body 1 comprises a bottom plate 13 and four side plates 14 connected with the bottom plate 13, and the four side plates 14 are connected in pairs in sequence. The side walls of the four side plates 14 facing the inner cavity 11 are provided with water absorbing layers 3, and the water absorbing layers 3 are made of square water absorbing cotton. Waterproof layer 2 and the layer 3 that absorbs water can be dismantled through magic subsides 4 and be connected. The magic tape 4 comprises a first magic tape 42 with a hook surface and a second magic tape 41 with a hair surface, the first magic tape 42 is arranged on the waterproof layer 2, and the second magic tape 41 is arranged on the water absorption layer 3.
Referring to fig. 4, the side of the box cover 12 facing the inner cavity 11 is also provided with a water-absorbing layer 3. The waterproof layer 2 of connection on case lid 12 can be dismantled through magic subsides 4 in the layer 3 that absorbs water, and on waterproof layer 2 was located to first magic subsides 42, second magic subsides 41 were located and are absorbed on the layer 3. During transportation of some cartons containing articles, the side of the carton having the cover 12 is generally required to be placed upward according to the requirements of the articles, and when the temperature of the high-temperature contents in the carton is reduced from high temperature to room temperature, the generated water vapor is heat water vapor, and the heat water vapor is collected upward and absorbed by the water absorbing layer 3 on the side wall of the cover 12, so that the possibility of the carton absorbing water vapor is reduced, and the possibility of the carton becoming damp and soft is further reduced.
Referring to fig. 1, two elongated reinforcing ribs 5 are disposed on the outer side walls of the four side plates 14 away from the inner cavity 11 along the depth direction of the box body 1. When the carton was placed at the pile, the one side that the carton had case lid 12 was placed up, and the intensity of reinforcing arris 5 can strengthen the carton reduces the possibility that the deformation took place for the carton to the life of extension carton.
The working principle is as follows: after the paper box with the high-temperature contents is packaged, the water vapor generated in the process that the temperature of the contents is reduced to the room temperature from the high temperature can be absorbed by the water absorbing layer 3 on the inner side wall of the paper box, so that the possibility that the paper box absorbs the water vapor is reduced, the possibility that the paper box is damped and softened is reduced, and the service life of the paper box is prolonged
After the contents in the carton are taken out, the water absorbing layer 3 absorbing water vapor can be directly detached in the process of processing the carton, the carton can be continuously recycled, or a new water absorbing layer 3 is replaced, and the carton is used for containing new high-temperature contents again, thereby reducing the waste of resources.
Example 2:
the structure of the coated carton for hot liquid filling is based on the embodiment 1 and is different from the embodiment 1 in the following points with reference to fig. 5 and 6: the water absorption layer 3 is water absorption paper. The outer side walls of the four side plates 14 departing from the inner cavity 11 are provided with two arched edges, and the central angles of the arched edges face the bottom plate 13. The one side that has case lid 12 to the carton is placed up, and when the carton pile was placed, the arch arris received pressure, and the pressure that the load that the top of arch arris bore produced can disperse and bear for both sides hunch foot to the bearing capacity of reinforcing carton reduces the possibility that the deformation took place for the carton.
Referring to fig. 7 and 8, the water collecting grooves 7 are arranged at the joints of the four side plates 14 and the bottom plate 13 along the length direction of the side plates 14, and the cross sections of the water collecting grooves 7 are U-shaped. One end of the water absorption layer 3 on the side plate 14 close to the bottom plate 13 extends to the bottom plate 13, and part of the water absorption layer 3 is accumulated in the water collection tank 7. The bottom plate 13 is provided with a first magic tape 42, and the bottom surface of the water absorption layer 3 facing the bottom plate 13 is provided with a second magic tape 41 matched with the first magic tape 42.
Some cartons that are equipped with article are in the transportation, because of the demand of article, generally can require the carton to have the one side of case lid 12 to place up, and the water vapor in the carton can gather at the inside wall of carton and become the drop of water, and the drop of water flows down to the catch basin along the inside wall of carton under self action of gravity, and then is absorbed by the layer 3 that absorbs water in the catch basin to reduce the possibility that the carton absorbs water vapor, and then reduce the possibility that the carton takes place to wet and become soft.
The above-mentioned embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws and protection within the scope of the present invention.
