Description

Plastic box

Technical Field

The invention relates to the field of machinery, in particular to a plastic box.

Background

The existing refrigerator storage box is generally integrally rectangular, so that when the storage box is used in a refrigerator, downward boxes can be stacked together, and the situation that the upper box extrudes food in the lower box to cause loss is prevented. However, such structures cannot be stacked one on another during transportation, which results in a large occupied area and a large transportation cost, and thus needs to be improved.

Disclosure of Invention

In order to solve the technical problem, the invention provides a plastic box. According to the invention, the plastic boxes are provided with the asymmetric wedge-shaped structures, so that when the two boxes rotate 180 degrees relatively, the two boxes can be used for placing food, so that the food cannot be extruded when the two boxes are stacked, and the boxes are nested and stacked at the same angle during transportation, so that the storage space is saved, and the transportation cost is saved.

The purpose of the invention is realized by the following technical scheme:

a plastic box comprises a box body, wherein a first bulge is formed in the middle of the inner wall of the left side of the box body in an inward protruding mode, and a second bulge is formed in the middle of the inner wall of the right side of the box body in an inward protruding mode; the first protruding part and the second protruding part are gradually narrowed from the bottom to the top, and the second protruding part is smaller than the first protruding part; the outer side of the first bulge part is provided with a first guide groove matched with the first bulge part, and the outer side of the second bulge part is provided with a second guide groove matched with the second bulge part; the top parts of the first guide groove and the second guide groove are fixedly provided with supporting plates; supporting parts are formed in the two sides of the second protruding part in a protruding mode, and guide grooves matched with the supporting parts are formed in the outer sides of the supporting parts.

In a further improvement, first avoiding grooves are formed between two sides of the first protruding part and the front side wall and the rear side wall of the box body.

In a further improvement, a second avoiding groove is formed in the concave part of the top of the supporting part.

In a further improvement, four corners of the bottom of the box body are respectively provided with a positioning convex strip.

In a further improvement, the box body is made of transparent plastic.

In a further improvement, the box body is coated with decorative stripes.

In a further improvement, the first and second protrusions are both wedge-shaped.

In a further improvement, the box body is integrally of a wedge-shaped structure gradually widening from the bottom to the top.

The invention has the beneficial effects that:

1. according to the invention, the plastic boxes are provided with the asymmetric wedge-shaped structures, so that the two boxes can be used for placing food when rotating 180 degrees relatively, so that the food cannot be extruded when being stacked mutually, and the boxes are nested and stacked mutually at the same angle during transportation, so that the storage space is saved, and the transportation cost is saved.

2. Set up and dodge the slot to when piling up after making the plastics box place article, there is ventilative clearance with the external world, the food of being convenient for breathes, prevents it and rot, extension food save time.

Drawings

The invention is further illustrated by means of the attached drawings, the content of which is not in any way limitative of the invention.

FIG. 1 is a first schematic structural diagram of the present invention;

FIG. 2 is a second schematic structural view of the present invention;

fig. 3 is a third schematic structural diagram of the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Example 1

A plastic box as shown in fig. 1 and 2 comprises a box body 1, a first protruding portion 2, a second protruding portion 3, a first guide groove 4, a second guide groove 5, a supporting plate 6, a supporting portion 7, a guide groove 8, a first avoiding groove 9, a second avoiding groove 10, a positioning convex strip 11 and a decorative strip 12.

Wherein, the middle part of the inner wall of the left side of the box body 1 is internally provided with a first bulge part 2 in an inward convex way, and the middle part of the inner wall of the right side is internally provided with a second bulge part 3 in an inward convex way; the first bulge part 2 and the second bulge part 3 are gradually narrowed from the bottom to the top, and the second bulge part 3 is smaller than the first bulge part 2; the outer side of the first bulge part 2 is provided with a first guide groove 4 matched with the first bulge part 2, and the outer side of the second bulge part 3 is provided with a second guide groove 5 matched with the second bulge part 3; the top parts of the first guide groove 4 and the second guide groove 5 are fixed with a supporting plate 6; the two sides of the second convex part 3 are convexly provided with supporting parts 7, and the outer sides of the supporting parts 7 are provided with guide grooves 8 matched with the supporting parts 6.

Therefore, when in transportation, the first lug boss 2 can be aligned with the first guide groove 4, and the second lug boss 3 can be aligned with the second guide groove 5 to be inserted downwards, so that the plastic boxes can be nested and stacked, and the storage space is saved.

When it is desired to store food therein and the stacking is such that the boxes are stacked in reverse between each other, i.e. rotated 180 ° towards each other. At this time, the outer portions of both sides of the first guide groove 4 are supported by the supporting portions 7, and the second guide groove 5 is supported by the pallet 6 above the first protrusion 2, thereby being stacked one on another.

In order to facilitate the clearance for ventilation between the stacked boxes, first avoiding grooves 9 are formed between the two sides of the first protruding part 2 and the front and rear side walls of the box body 1. The top of the supporting part 7 is recessed to form a second avoiding groove 10, and the whole box body 1 is of a wedge-shaped structure gradually widening from the bottom to the top. Thereby facilitating ventilation and corrosion prevention.

Four corners of the bottom of the box body 1 are respectively provided with a positioning convex strip 11. Thereby preventing the stacked cassettes from slipping off.

The box body 1 is made of transparent plastic. The bottom of the box body 1 is also coated with a decorative stripe 12.

The first 2 and second 3 bosses are wedge shaped to facilitate quick nesting of the stack.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
