Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings 1-5.

The utility model provides a PET plastic uptake box for food package, includes box body 1 and detains lid 2 at 1 top of box body, 1 lateral wall top of box body is outwards turned over and is rolled over the turn-ups 3 that has the round cross-section to be the L type, and wherein 2 bottom borders of lid are provided with shirt rim 4 of round cover on turn-

ups

3, and 2 middle departments of lid still are provided with the depressed part 5 at top in the embedding box body 1, top, shirt rim 4 cover are fixed with realizing

lid

2 and 1 swing joint of box body on turn-ups 3 in the 1 opening of box body in through depressed part 5 embedding to it is sealed in order to prevent food outflow to open-top with 1 box body.

The ventilation barrel is characterized in that a ventilation barrel 6 with a sealed top opening is arranged in the recessed portion 5, a ventilation opening 7 is arranged on the top wall of the ventilation barrel 6, a screw pipe 8 is arranged on the recessed portion 5 under the ventilation opening 7, ventilation holes 9 are uniformly formed in the side wall of the lower half portion of the screw pipe 8, a through hole 10 communicated with the screw pipe 8 is formed in the bottom wall of the recessed portion 5, a screw rod 11 with the bottom end inserted into the through hole 10 is screwed in the screw pipe 8, a fixed block 12 located above the screw pipe 8 is arranged at the top end of the screw rod 11, the diameter of the fixed block 12 is smaller than the inner diameter of the ventilation opening 7 and larger than the diameter of the screw pipe 8, and a convex block 13 is further arranged at the top end of the fixed block 12.

As shown in fig. 4, when the temperature is too high in the box body 1, the fixed block 12 is rotated by the convex block 13 to drive the screw rod 11 to rotate in the screw tube 8, so that the bottom end of the screw rod 11 is rotated out from the through hole 10, the fixed block 12 is rotated out from the ventilation port 7, at the moment, high-temperature gas in the box body 1 passes through the through hole 10, the inner diameter of the screw tube 8 and the ventilation holes 9 flow into the ventilation barrel 6, and finally is discharged from the ventilation port 7, so that the food in the box body 1 can be cooled by the mode to prevent the food from going bad quickly, and the box cover 2 is opened by the food in the box body 1 after exhausting, so that the food is not easy to scald when being eaten.

In the process, the screw 11 prevents high-temperature gas in the box body 1 from being directly upwards sprayed out through the through hole 10 and the inner diameter of the screw pipe 8, but the gas is bent to flow into the ventilation cylinder 6 through the ventilation holes 9 and is finally discharged from the ventilation port 7, so that the flow rate of the gas is reduced to prevent the gas from hurting people when the gas is sprayed out.

Wherein, the vertical end of the turn-ups 3 and the skirt 4 are correspondingly provided with a bayonet I14 and a bayonet II15, a Contraband-type rod 16 with an outward opening is arranged between the turn-ups 3 and the side wall of the box body 1, the upper horizontal end of the Contraband-type rod 16 passes through the bayonet I14 and extends into the bayonet II15, the lower horizontal end of the Contraband-type rod 16 is positioned at the bottoms of the skirt 4 and the turn-ups 3, the tail ends of the lower horizontal ends of a plurality of groups of Contraband-type rods 16 on the same side are fixedly connected through a push plate 19, the outer side wall of the box body 1 is also provided with a fixed seat 17 corresponding to the Contraband-type rod 16, and the fixed seat 17 is provided with a spring 18 fixedly connected with the back of the Contraband-type rod 16.

As shown in fig. 3, the springs 18 at both sides of the box body 1 in the length direction stretch to push the Contraband-type rod 16 to move outwards, so that the upper horizontal end of the Contraband-type rod 16 passes through the bayonet I14 and extends into the bayonet II15, and the skirt 4 is prevented from sliding off the flange 3 in a manner that the Contraband-type rod 16 catches the bayonet I14 and the bayonet II15, thereby achieving the purpose of improving the stability between the box cover 2 and the box body 1, and preventing the problem that the box cover 2 slides off the top of the box body 1 without human intervention.

As shown in fig. 5, when the box cover 2 needs to be opened, the pressing push plate 19 drives a plurality of Contraband-type rods 16 to move towards the middle of the box body 1, at this time, the Contraband-type rod 16 presses the spring 18 to contract, and drives the upper horizontal end of the Contraband-type rod 16 to slide out of the bayonet II15, at this time, the upper horizontal end of the Contraband-type rod 16 cannot hang the bayonet II15, so that people can lift the box cover 2 upwards to drive the skirt 4 to be drawn out from the flange 3, and thus, the separation work between the box cover 2 and the box body 1 is realized.

Preferably, one end face of the fixed seat 17 is provided with a groove for accommodating the tail end of the spring 18, wherein one end of the spring 18 is fixedly bonded in the groove.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
