Technical Field

[0001] The utility model belongs to the technical field of packaging trays, and particularly relates to a fresh-keeping packaging tray. Background Art

[0002] A fresh-keeping packaging tray, also known as a fresh-keeping packaging box, as the name implies, is a box used to package products, and can be classified according to materials such as: paper box, iron box, wooden box, cloth box, leather box, acrylic box, corrugated packaging box, PVC box, etc.

[0003] The fresh-keeping packaging tray is used for preserving products, for example: crabs, etc. Crabs are one of the favorite aquatic products of people. Especially lake crabs and hairy crabs, also known as mitten crabs, contain rich protein and trace elements, which have a good nourishing effect on the body, and also have an anti-tuberculosis effect. Eating crabs is of great benefit to the recovery of tuberculosis, and it is one of the favorite aquatic products of people. In the current sales of crabs, most of the crab packages are tied with ropes, which takes a lot of time. Therefore, in order to solve the problem of time-consuming packaging, crab packaging trays have emerged on the market to package crabs. However, the existing crab packaging trays are generally simple plastic trays. When packaging, the crabs are first placed in the plastic tray, and at the same time, ice cubes are placed in the plastic tray. The crabs will go into dormancy (hibernation) in a low-temperature environment, reducing the energy consumption of the crabs. Then, oxygen is filled into the plastic tray, and finally, a sealing film is sealed at the box mouth of the plastic tray to seal the inside of the plastic tray. However, in actual use, the existing crab packaging trays have the following defects: during transportation, the ice cubes will collide with the crabs when placed together, which is likely to cause the crabs to break their legs or die, resulting in certain economic losses.

[0033] In one embodiment of the present utility model, referring to Figures 1-3 , a fresh-keeping packaging tray is provided, which includes an ice cube box body 100 and a product box body 200.

[0034] Among them, referring to Figure 2 and Figure 3 , the ice cube box body 100 is provided with a receiving cavity 110 having an upper cavity opening 120.

[0035] Among them, referring to Figure 2 and Figure 3 , the product box body 200 is provided with at least one product placement cavity 210, and the product placement cavity 210 has an upper box opening 220. The product box body 200 is placed in the receiving cavity 110 from the upper cavity opening 120, and an ice cube placement cavity 130 is formed between the ice cube box body 100 and the product box body 200. A plurality of first through holes 211 communicating with the ice cube placement cavity 130 are provided through the bottom of the product placement cavity 210.

[0036] Among them, the sealing film 300 is adhered to the upper ends of the ice cube box body 100 and the product box body 200 and seals the upper box opening 220.

[0037] Compared with the prior art, one or more of the above technical solutions in the fresh-keeping packaging tray provided by the embodiment of the present invention at least have one of the following technical effects:

[0038] Refer to Figure 2 and Figure 3 , when in use, put ice cubes at the bottom of the accommodating cavity 110 so that the ice cubes are located in the ice cube placing cavity 130, then place the product box body 200 into the accommodating cavity 110 from the upper cavity opening 120, put crabs into the product placing cavity 210, then fill the product placing cavity 210 with oxygen, and finally adhere the sealing film 300 to the upper ends of the ice cube box body 100 and the product box body 200 and seal the upper box opening 220, so that the crabs are in a sealed environment, completing the packaging of the crabs; therefore, the crabs and ice cubes are placed separately by the ice cube box body 100 and the product box body 200. During transportation, the ice cubes and crabs will not collide, avoiding the crabs' legs from breaking or the crabs from dying due to the collision, playing a role in protecting the crabs.

[0039] Moreover, the cold air formed by the ice cubes in the ice cube placing cavity 130 flows into the product placing cavity 210 through the first through hole 211, providing a low-temperature environment for the crabs in the product placing cavity 210, enabling the crabs to go into dormancy (hibernation), reducing the energy consumption of the crabs, and having a good fresh-keeping effect. And the first through hole 211 is relatively small, and the ice cubes in the ice cube placing cavity 130 cannot pass through the first through hole 211 into the product placing cavity 210, and the structure is reliable.

[0040] Further, refer to Figure 2 and Figure 3 , the upper side dimension of the upper cavity opening 120 is increased to form a first limiting groove 121, and the outer periphery of the upper end of the product box body 200 extends outward to form a first supporting platform 201. Place the product box body 200 into the accommodating cavity 110 from the upper cavity opening 120, and make the first supporting platform 201 fit and be placed in the first limiting groove 121, and the lower end surface of the first supporting platform 201 abuts against the groove bottom surface of the first limiting groove 121, so that the product box body 200 is positioned and placed in the accommodating cavity 110, and the product box body 200 will not move in the accommodating cavity 110, and the structure is reliable.

[0041] Further, refer to Figure 2 and Figure 3, a second support platform 101 extends outward from the upper peripheral edge of the ice cube tray main body 100, and the upper end surfaces of the first support platform 201 and the second support platform 101 are flush. The sealing film 300 is fixedly bonded to the upper end surfaces of the first support platform 201 and the second support platform 101, so that the sealing film 300 is firmly bonded to the upper ends of the ice cube tray main body 100 and the product box main body 200. Among them, the sealing film 300 can be fixedly adhered to the first support platform 201 and the second support platform 101 by ultrasonic welding, with a simple structure and convenient processing.

[0042] Further, referring to Figure 2 and Figure 3 , the product box main body 200 is provided with a plurality of product placement cavities 210, and at least one crab can be placed in each product placement cavity 210, so that the product box main body 200 can hold multiple crabs to meet the usage requirements.

[0043] Further, referring to Figure 2 and Figure 3 , a partition plate 212 is provided between two adjacent product placement cavities 210. The partition plate 212 is provided with a plurality of second through holes 213. The second through holes 213 communicate the two adjacent product placement cavities 210, and the cold air in the two product placement cavities 210 can circulate with each other through the second through holes 213, so that the temperature in each product placement cavity 210 is kept balanced, and the fresh-keeping effect is good.

[0044] In another embodiment of the present invention, referring to Figure 2 and Figure 3 , the upper side dimension of the upper box opening 220 is increased to form a second limiting groove 221. The second limiting groove 221 is used to fit and place a baffle 230. The baffle 230 covers the upper box opening 220, and the sealing film 300 covers the baffle 230. The baffle 230 is placed in the second limiting groove 221, so that the baffle 230 covers the upper box opening 220 of the product placement cavity 210. The baffle 230 plays a protective role for the sealing film 300 to prevent the sharp spines of the crabs from piercing the sealing film 300, and the structure is reliable.

[0045] Among them, referring to Figure 2 and Figure 3 , the baffle 230 can be a plastic plate, a metal plate, a glass plate, or a wooden plate, etc., which is not limited here. The ice cube tray main body 100 and the product box main body 200 can be plastic suction boxes.

[0046] Further, referring to Figure 2 and Figure 3 , an opening groove 222 is provided at the edge of the second limiting groove 221. The opening groove 222 is used to remove the baffle 230.

[0047] Further, referring to Figure 2 and Figure 3 , a cut groove 240 is provided on one side edge of the second limit groove 221. The baffle 230 avoids the cut groove 240. An indicating cut line 340 corresponding to the cut groove 240 is provided on the upper surface of the sealing film 300, and a text description is provided beside the indicating cut line 340. Specifically, the user uses a small knife to pierce through the indicating cut line 340 and extend it into the cut groove 240, and then cuts along the indicating cut line to open the sealing film 300, which is convenient for the user to tear off the sealing film 300. Also, the cut groove 240 plays a guiding role for the small knife, guiding the movement of the small knife to prevent the small knife from deviating.

[0048] Further, referring to Figure 2 and Figure 3 , at least one corner of the sealing film 300 extends out of the ice cube box body 100 to form a tearing part 310, and the user can hold the tearing part 310 with the hand to tear off the sealing film 300.

[0049] Further, referring to Figure 2 and Figure 3 , a plurality of vertically arranged reinforcing rib strips (not shown in the figure) are provided on the outer walls of the ice cube box body 100 and the product box body 200. The reinforcing rib strips are used to enhance the strength of the ice cube box body 100 and the product box body 200, so that the ice cube box body 100 and the product box body 200 are not easily damaged and the structure is stable.

[0050] The rest of this embodiment is the same as that of the first embodiment. For the features not explained in this embodiment, the explanations of the first embodiment are adopted and will not be elaborated here.
