Fruit and vegetable packaging box capable of improving preservation effect

Technical Field

The utility model belongs to the technical field of the packing carton technique and specifically relates to a can improve fruit vegetables packing carton of fresh-keeping effect.

Background

The fruit and vegetable packing box is one kind of box for holding and conveying fruit and vegetable.

The current chinese patent with grant publication number CN204507775U discloses a fruit and vegetable packing box, which comprises a box cover and a lower box body, wherein the box cover and the lower box body are both provided with accommodating cavities, the accommodating cavities are combined to form accommodating spaces for fruits and vegetables, and the bottom of the accommodating cavity of the lower box body is additionally provided with an elastic support to prevent the fruits and vegetables from being placed in the accommodating cavities. The elastic support isolates a buffer space at the bottom of the accommodating cavity of the lower box body so as to prevent fruits and vegetables from shaking and provide vibration reduction for the fruits and vegetables.

The above prior art solutions have the following drawbacks: when the packing box is used for conveying fruits and vegetables in a long distance, the fruits and vegetables are sealed in the accommodating space for a long time, the freshness of the fruits and vegetables is easily influenced, and even the fruits and vegetables are rotten, so that the freshness is to be improved.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a can improve the fruit vegetables packing carton of fresh-keeping effect, it has the in-process that can carry the fruit vegetables in long-distance, keeps the fruit vegetables fresh, prevents the rotten advantage of fruit vegetables.

The utility model provides a can improve fruit vegetables packing carton of fresh-keeping effect, includes outer box body and the flip that can overturn the lid and fit outer box body upper surface, outer box body is inside to be provided with the interior box body that is used for placing fruit, outer box body diapire just is located interior box body below and is provided with the embedding groove, form first fresh-keeping chamber between outer box body inside wall and the interior box body lateral wall, be provided with the ice bag in embedding groove and the first fresh-keeping chamber respectively.

Through adopting above-mentioned technical scheme, through add in first fresh-keeping chamber and embedded groove and establish the ice bag and maintain the transportation the utility model discloses inside comparatively stable specific low temperature to keep the fresh sense of fruit vegetables in long-distance transport process, prevent that rotten phenomenon from appearing in the fruit vegetables.

Furthermore, the upper surface of the inner box body and the periphery of the inner box body extend to form a mounting plate, a plurality of locking protrusions are integrally formed on the inner side wall of the outer box body along the circumferential direction of the outer box body, and a locking groove for embedding each locking protrusion is formed in the outer side wall of the mounting plate.

Through adopting the technical scheme, because the utility model discloses a plastics material has certain flexibility, so setting up of locking arch and locking recess has realized that the box body is connected with dismantling of outer box body, only need through change ice bag alright realize right the utility model discloses a cyclic utilization promotes green.
