Description

TECHNICAL FIELD

[0001] The present application relates to the field of carton, in particular to a corrugated carton. BACKGROUND

[0002] The corrugated carton is a common packaging method, which is made of corrugated paperboard and has the advantages of lightness, environmental protection and economy. The corrugated carton is widely used in the fields of logistics and transportation and is mainly used for packaging and transporting various commodities.

[0003] Based on the above-mentioned characteristics of lightness, environmental protection and economy, the corrugated carton is particularly suitable for packaging and transporting agricultural products, such as fruits and vegetables. Most fruits and vegetables are sold in a thin and many sales strategy, which inevitably requires farmers to reduce costs in the process of production, transportation and sales to maximize profits. The use of corrugated carton can also reduce the risk of damage to fruits and vegetables due to vibration and collision. Fruits and vegetables as food also have certain requirements for packaging. Therefore, the corrugated carton which is safe, non-toxic and economical is a better choice.

[0004] However, the use of corrugated carton for packaging fruits and vegetables also faces the problem of poor air permeability. If there is no proper ventilation condition, bacteria and microorganisms are easy to breed in the environment with poor air permeability, thereby increasing the risk of contamination of fruits and vegetables and threatening the safety of fruits and vegetables. In addition, the packaging with poor air permeability may hinder the necessary oxidation reaction, resulting in loss of freshness of fruits and vegetables.

[0005] Although the prior art solves the above-mentioned problem of poor air permeability of the carton by opening a ventilation hole on the corrugated carton, there are still certain limitations in opening the ventilation hole on the carton only. The humidity inside the corrugated carton is more easily affected by the humidity outside due to the existence of the ventilation hole. When the corrugated carton is used to package fruits with high water content such as watermelon and Hami melon, the internal environment of the corrugated carton can be maintained at a suitable humidity. However, during transportation, especially in southern China, the temperature is high and the humidity is large,

[0006] When the transport vehicle passes through a region with high humidity, the humidity outside is greater than the humidity inside the corrugated carton. The humidity inside the corrugated carton is affected by the humidity outside due to the existence of the ventilation hole, which leads to an increase in the humidity inside the corrugated carton and further increases the surface humidity of fruits with high water content such as watermelon and Hami melon, thereby accelerating the growth of rot and mold. Therefore, the corrugated carton with a ventilation hole alone cannot meet the needs of packaging and transporting different types of fruits and vegetables. SUMMARY

[0007] The present application aims to provide a corrugated carton to solve the above-mentioned problems. The specific technical solutions are as follows:

[0008] A corrugated carton for storing fruits and vegetables, comprising a carton body, the carton body being provided with a gas-permeable hole, the carton body being provided with a water-absorbing element and a baffle, the water-absorbing element bearing the baffle so that the baffle is arranged against the gas-permeable hole, the baffle being provided with an opening in the gas flow path of the gas-permeable hole, the water-absorbing element being adjusted in the vertical direction after being softened by moisture, thereby adjusting the gas flow capacity of the gas-permeable hole.

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0035] In this document, reference to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with other embodiments in combinations other than the ones explicitly presented if such embodiments result in equivalent systems.

[0036] A corrugated packaging carton is set forth herein, mainly for packaging and storing fruits and vegetables. The corrugated packaging carton is provided with an air vent 2 to enable the inside of the corrugated packaging carton to communicate with the outside air. It can be understood that, after fruits and vegetables are stored in the corrugated packaging carton, the fruits and vegetables placed relatively higher in the corrugated packaging carton can be frequently replaced, and can also be contacted with the outside air through the opening of the corrugated packaging carton or a possible opening designed for convenient gripping. However, the fruits and vegetables stacked relatively lower in the corrugated packaging carton or close to the bottom surface of the inside of the corrugated packaging carton do not have this ventilation condition. Therefore, the air vent 2 is usually arranged at the bottom end of the side of the corrugated packaging carton.

[0037] Please refer to Figures 1-3,In order to perfect the design of the air vent 2, so that the corrugated packaging carton has a certain moisture-proof ability, the application provides a corrugated packaging carton, which comprises a carton body 1, the carton body 1 is provided with an air vent 2, and the air vent 2 is arranged at the bottom end of the side of the carton body 1; the carton body 1 is provided with a water absorbing part 4 and a baffle 3; specifically, since the carton body 1 itself has a containing space for storing fruits and vegetables, the water absorbing part 4 and the baffle 3 can be respectively arranged on the inner bottom surface and the inner wall of the containing space of the carton body 1; the water absorbing part 4 bears the baffle 3; the baffle 3 is provided with an opening 31 on the gas flow path of the air vent 2; the water absorbing part 4 adjusts the position of the baffle 3 in the vertical direction according to the softening degree of the water absorbing part 4, so as to adjust the gas flow of the air vent 2;

[0038] In a specific application, after the water absorbing part 4 absorbs water, the body will soften; since the baffle 3 is much heavier than the water absorbing part 4, the water absorbing part 4 cannot completely support the baffle 3 after absorbing water, so that the baffle 3 sinks, that is, the height of the baffle 3 decreases; for example, the baffle 3 has the opening 31 and communicates with the air vent 2; when the height of the baffle 3 decreases, the opening 31 on the baffle 3 is misaligned or mispositioned with the air vent 2 of the carton body 1, so as to realize that the air vent 2 changes from an open state to a semi-closed state or a closed state; closing the air vent 2 can prevent the humidity in the carton body 1 from being affected by the humidity outside.

[0039] It should be noted that the water absorbing part 4 is a water absorbing material, which can affect the surrounding humidity; the water absorbing part 4 will soften after absorbing a certain amount of water; please refer to Figure 4 and Figure 5 The water absorbing part 4 comprises a paper support column 41 and a solid desiccant 42; the paper support column 41 is provided with a containing space for filling the solid desiccant 42; the paper support column 41 is provided with a plurality of through holes communicating with the containing space; the solid desiccant 42 is responsible for absorbing water in the air and collecting water on the inner bottom surface of the carton body 1; the solid desiccant 42 will also gradually become wet during the water absorption process; since the solid desiccant 42 is arranged in the paper support column 41, the paper support column 41 will be in contact with the solid desiccant 42 in nature, that is, the paper support column 41 will also gradually soften; at this time, the force balance between the baffle 3 and the paper support column 41 will be broken; the paper support column 41 cannot support the baffle 3 due to softening; the softened part of the paper support column 41 will be extruded and compressed to deform or even break, so that the baffle 3 sinks, and the air vent 2 is gradually covered by the baffle 3;

[0040] Definition of watermelon, cantaloupe and other fruits with high water content, when the air humidity reaches a value X, the fruit is easy to rot or the surface of the fruit is easy to grow mold, define the use of corrugated carton packaging above fruit, the humidity in the corrugated carton is maintained under the influence of solid desiccant 42 at value Y, value Y is less than value X, define when the humidity in the corrugated carton reaches value Z, part of the paper support column 41 in contact with the solid desiccant 42 will be damp and softened so as to be unable to support the baffle 3, value Z is less than value X, and value Z is greater than value Y, define the humidity of the outside is value A, value A is greater than value Z, when the humidity of the outside continuously influences the internal humidity of the corrugated carton packaging through the air hole, makes value Y continuously increases, eventually makes value Y greater than value Z, at this time, the bottom of the paper support column 41 is softened and cannot support the baffle 3, the baffle 3 is lowered and gradually covers the air hole 2.

[0041] Since the present application is mainly used for packaging and storing fruits and vegetables, it is inevitable to protect the fruits and vegetables, and the existence of the air hole 2 will also make some pests easy to enter the inside of the carton body 1 through the air hole 2, therefore, please refer to Figure 2 and Figure 7 , the present application also provides an embodiment, which is further optimized for the opening 31, that is, the opening 31 is a mesh opening or an interception net is installed in the opening 31, which can prevent some pests from entering the inside of the carton body 1, reduce the risk of damaging fruits and vegetables due to pests, avoid the rot of fruits and vegetables due to pests, preferably, the baffle 3 has a recess 32, and the mesh opening is arranged in the recess 32, when the baffle 3 is lowered relative to the air hole 2, the mesh opening can be avoided to directly abut on the air hole 2 and displace, reducing the risk that the protruding edge corners or burrs formed in the process of forming the mesh opening 31 are stuck in the air hole 2 and cannot displace.

[0042] Please refer to Figure 4 , regarding the paper support column 41, the present application provides various types of paper support column 41: in some embodiments, the number of paper support columns 41 is two, the two paper support columns 41 are arranged in parallel and perpendicular to the inside bottom surface of the carton body, in other embodiments, the number of paper support columns 41 is two, the two paper support columns 41 are arranged in an inclined and symmetrical manner to form a triangular support structure to support the baffle 3, which can be flexibly selected according to the weight of the supported baffle 3, and the shape of the paper support column 41 can be cylindrical or cuboid.

[0043] Please refer to Figure 2 , Figure 3 and Figure 7In a preferred embodiment, the air vent 2 is not completely covered by the baffle 3, that is, the air flow of the air vent 2 is not equal to zero. As can be seen from the above embodiments, the technical solution is to change the height of the baffle 3 by using the water absorption softening characteristics of the paper support column 41. However, the water absorption amount of the solid desiccant 42 or the paper support column 41 is uncontrollable. In order to ensure that the air vent 2 is not completely covered by the baffle 3, it is necessary to ensure that the baffle 3 has a minimum height. At this position, the baffle 3 will cover a large area of the air vent 2, but there is still a small overlap between the air vent 2 and the opening 31 to maintain the basic air flow. In this way, the air vent 2 can reduce the influence of external humidity on the humidity inside the carton body 1 to the greatest extent without losing the air permeability, so that the humidity inside the carton can be maintained in a relatively suitable state. In order to achieve the above effect, the application also provides an embodiment:

[0044] Please refer to 2、 Figure 6 and Figure 8 The application also includes a support column 5 which is detachably connected to the carton body 1. Specifically, the support column 5 is vertically inserted into the carton body 1, and the bottom of the support column 5 abuts against the inner bottom surface of the carton body 1. The support column 5 is provided with a notch at the abutment position to accommodate the baffle 3. The baffle 3 is slidably connected to the notch of the support column 5. The notch is provided with a protruding block 51 to limit the baffle 3. By introducing the support column 5 to install the baffle 3, the strength of the carton body 1 can be strengthened by the support column 5, and the support column 5 can be used to facilitate the replacement of the water absorption member 4 in a detachable manner with the carton body 1. In addition, the design of the protruding block 51 ensures that the baffle 3 has a limited descending height during the descending process, and the maximum descending height corresponds to the minimum height of the baffle 3 in the above embodiment, so as to ensure that the air vent 2 and the opening 31 are connected with the minimum area.

[0045] Regarding the replacement of the water absorption member 4, as can be seen from the above embodiments, the application has the possibility of being reused. In most cases, only the paper support column 41 will be damaged due to moisture and pressure. Therefore, when installing the water absorption member 4, that is, the paper support column 41, it can be inserted or bonded at the bottom of the baffle 3, and then inserted into the inside of the carton body 1 through the support column 5. When the paper support column 41 needs to be replaced, the softened part of the paper support column 41 will remain in the inside of the carton body 1. After drying, the carton body 1 is inverted, and the softened part of the paper support column 41 can be taken out. The part remaining at the bottom of the baffle 3 will be taken out when the support column 5 is detached from the carton body 1. The new paper support column 41 can be connected to the bottom of the baffle 3 to reuse the carton body 1 and the support column 5.

[0046] In some embodiments, the inner bottom surface of the carton body 1 is provided with a groove 11 for mounting the paper support column 41, and the inner wall of the groove 11 is covered with a water-impermeable film. As known from the above embodiments, the paper support column 41 is filled with solid desiccant 42, and the paper support column 41 is prone to breakage after absorbing water due to the plurality of through holes formed therein. At this time, the groove 11 can be used to store the solid desiccant 42 scattered after the paper support column 41 breaks, and the groove 11 also functions to limit the paper support column 41, especially in the case of the above-mentioned two paper support columns 41 being inclined and symmetrically arranged, to prevent the inclined paper support column 41 from continuously deviating outward after being pressed by the baffle 3.

[0047] Please refer to Figure 2 In some embodiments, the carton body 1 is rectangular in shape, and the inner corners of the carton body 1 are provided with connecting grooves 12 for mounting the support columns 5. The connecting grooves 12 are provided with limiting plates 13 at the groove openings. The support column 5 comprises a paperboard bent to form two bent surfaces, and only one of the bent surfaces has a notch. The rectangular carton body 1 has a front panel, a left panel, a right panel, and a rear panel, and the air vents 2 are arranged on the left panel and the right panel. Since the support column 5 is a bent paperboard, and only one of the bent surfaces has a notch for mounting the baffle 3, it is only necessary to exchange the two support columns 5 on the same side of the left panel and the right panel, and then insert them into the carton body 1. The bent surface of the support column 5 without a notch will completely block the air vents 2, so that the carton body 1 is no different from an ordinary carton. In addition to being used for packaging and storing fruits and vegetables, the corrugated packaging carton of the present application can also be assembled into a non-air-permeable carton to package and store goods that do not require ventilation conditions.

[0048] It will be obvious to a person skilled in the art that, without departing from the spirit or essential characteristics of the application, the present application can be implemented in other specific forms. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
