Description

Technical Field

[0001] The invention relates to the field of plastic packaging, and in particular to a plastic packaging container for storing food and a storage method thereof. Background Art

[0002] Plastic packaging containers for food storage are extremely common in modern life. They are light, corrosion-resistant, and highly plastic, and are widely used in food packaging, storage, and transportation.

[0003] Food is processed and made from fresh ingredients. In order to ensure the freshness and storage of food, it is generally placed in a plastic storage box, and then a layer of aluminum foil is laid in the plastic storage box, and then the food is placed in the plastic storage box. After the food is placed, ice cubes are placed on both sides of the storage box. This creates a low-temperature environment in the storage box, and the aluminum foil and plastic storage box block the rapid entry of external heat, so that the food in the plastic storage box can be preserved for a longer time and prevents the food from quickly deteriorating and damaging.

[0004] In the prior art, aluminum foil is laid in a plastic storage box, and then ice cubes are added into the plastic storage box, so that the food placed in the plastic storage box can be preserved for a longer period of time. However, in the hot summer season, although the plastic storage box and the aluminum foil block most of the external heat from entering the interior of the plastic storage box, the ice cubes placed in the plastic storage box will still melt due to the high temperature, and the water flow from the melted ice cubes will accumulate in the plastic storage box, which will cause the water flow to contact the food, causing the food to be damaged or the appearance of the food to be destroyed, resulting in the inability to be sold or the customer returning the food due to damage when receiving the food. Summary of the invention

[0033] Beneficial effects of the present invention:

[0034] (1) Open the box door and place the food on the lifting assembly in the storage box. Drive the lifting assembly to descend through the driving assembly, so that the lifting assembly and the food move into the working box. Then place ice cubes in the gap between the inner plate and the partition. After placing the ice cubes, place a water-absorbing sponge pad on the inner plate below the ice cubes. This arrangement allows the ice water to flow into the sponge pad, so that the food is separated from the melted ice water, and the ice water does not flow into the food to damage the food.

[0035] (2) When food needs to be taken out of the storage box, the driving assembly raises the lifting assembly so that the lifting assembly and the food are lifted out of the storage box. This is designed to facilitate the staff to take the food out and avoid the situation where some food needs to be lifted out from the bottom and the staff extends their arms into the storage box. When taking the food out, the staff may accidentally damage the food with their elbows, which results in the food being unable to be sold.

[0036] (3) When the driving component drives the lifting component to rise, the driving component also drives the squeezing component to move. The moving squeezing component squeezes the placed water-absorbing sponge to allow the water-absorbing sponge to discharge the water inside. This setting is to keep the water-absorbing sponge dry so that it can continue to absorb ice water when used next time, so that there is no accumulation of ice water in the storage box;

[0037] (4) When the squeezing component squeezes the absorbent sponge, ice water will be squeezed out. At this time, the driving component will drive the switch component to move. The movement of the switch component causes the squeezed ice water to flow out from the bottom of the storage box. This setting is to ensure that the storage box remains dry, and the switch component allows the entire storage box to form a closed space to reduce the outflow of cold air and the entry of hot air, so as to avoid the storage box being kept open all the time, which will accelerate the melting of ice cubes in the storage box and cause the food in the storage box to deteriorate and be damaged.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The staff opens the door 5 on the storage box 1, puts the food into the lifting assembly in the storage box 1, drives the lifting assembly to slowly descend into the interior of the storage box 1 through the driving assembly, and then places ice cubes and other materials on the inner plate 38. When it is needed to be taken out, the lifting assembly slowly rises to the top of the storage box 1. When the lifting assembly moves upward, the driving assembly also drives the squeezing assembly 01 and the switch assembly 03 to move, so that the melted ice water can be discharged from the storage box 1;

[0057] The food is placed on the lifting assembly in the storage box 1 by opening the box door 5, and the lifting assembly is driven by the driving assembly to descend, so that the lifting assembly and the food are moved into the working box, and then ice cubes are placed in the gap between the inner plate 38 and the partition. After the ice cubes are placed, a water-absorbing sponge pad is placed under the ice cubes on the inner plate 38. This arrangement allows the ice water to flow into the sponge pad, so that the food is separated from the melted ice water, and the ice water is not allowed to flow into the food to cause damage to the food. When the food needs to be taken out of the storage box 1, the lifting assembly is raised by the driving assembly, so that the lifting assembly and the food are lifted out of the storage box 1. This arrangement is to facilitate the staff to take it out, and avoid that some food needs to be lifted out from the bottom, and the staff's arms are fully extended into the storage box 1. When taking it out, the elbows accidentally damage the food, resulting in the food being unable to be sold;

[0058] When the driving component drives the lifting component to rise, the driving component also drives the squeezing component 01 to move, and the moving squeezing component 01 squeezes the placed water-absorbing sponge to make the water-absorbing sponge discharge the water inside. This setting is to keep the water-absorbing sponge dry so that it can continue to absorb ice water when used next time, so that there is no accumulation of ice water in the storage box 1;

[0059] When the squeezing component 01 squeezes the absorbent sponge, ice water will be squeezed out. At this time, the driving component will drive the switch component 03 to move. The movement of the switch component 03 allows the squeezed ice water to flow out from the bottom of the storage box 1. This arrangement is to ensure that the storage box 1 remains dry, and the switch component 03 allows the entire storage box 1 to form a closed space to reduce the outflow of cold air and the entry of hot air, so as to avoid the storage box 1 being kept open all the time, which will accelerate the melting of ice cubes in the storage box 1 and cause the food in the storage box 1 to deteriorate and be damaged.

[0079] See also Figures 1 to 9 As shown, a storage method of a plastic packaging container for storing food, the storage method comprises the following steps:

[0080] S1: The staff puts the food on the support plate in the storage box 1, and after placing it, turns the handle 4 to move the food and the support plate into the storage box 1, and then puts ice cubes into the partition formed by the inner plate 38 and the partition;

[0081] S2: When the food in the storage box 1 needs to be taken out, the staff opens the door 5 on the storage box 1 and rotates the handle 4, so that the lifting rod 11 will move the supporting platform 14 upward, so that the food on the supporting platform 14 is away from the inside of the storage box 1, allowing the customer to take the food;

[0082] S3: When the handle 4 is turned, the squeezing plate 21 and the switch plate 28 will also move, so that the water dripping from the melted ice cubes can be discharged from the storage box 1;

[0083] S4: After the customer has taken all the food from the supporting platform 14, the customer rotates the handle 4 to return the supporting plate to the storage box 1, and then closes the box door 5.

[0084] The working principle of the present invention is as follows: by opening the box door 5 and placing the food on the lifting assembly in the storage box 1, the lifting assembly is driven by the driving assembly to descend, so that the lifting assembly and the food are moved into the working box, and then ice cubes are placed in the gap between the inner plate 38 and the partition. After the ice cubes are placed, a water-absorbing sponge pad is placed on the inner plate 38 below the ice cubes. This arrangement allows the ice water to flow into the sponge pad, so that the food is separated from the melted ice water, and the ice water is not allowed to flow into the food to cause damage to the food. When the food needs to be taken out of the storage box 1, the lifting assembly is raised by the driving assembly, so that the lifting assembly and the food are lifted up from the storage box 1. This arrangement is to facilitate the staff to take it out, and avoid that some food needs to be lifted out from the bottom, and the staff's arms are fully extended into the storage box 1. When taking it out, the elbows accidentally damage the food, resulting in the inability to sell the food;

[0085] When the driving component drives the lifting component to rise, the driving component also drives the squeezing component 01 to move, and the moving squeezing component 01 squeezes the placed water-absorbing sponge to make the water-absorbing sponge discharge the water inside. This setting is to keep the water-absorbing sponge dry so that it can continue to absorb ice water when used next time, so that there is no accumulation of ice water in the storage box 1;

[0086] When the squeezing component 01 squeezes the absorbent sponge, ice water will be squeezed out. At this time, the driving component will drive the switch component 03 to move. The movement of the switch component 03 allows the squeezed ice water to flow out from the bottom of the storage box 1. This arrangement is to ensure that the storage box 1 remains dry, and the switch component 03 allows the entire storage box 1 to form a closed space to reduce the outflow of cold air and the entry of hot air, so as to avoid the storage box 1 being kept open all the time, which will accelerate the melting of ice cubes in the storage box 1 and cause the food in the storage box 1 to deteriorate and be damaged.

[0087] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
