Abstract

The utility model discloses a laminated food packing box used for packaging the frozen chilled food. The packing box is provided with an inner box for containing food, and a plurality of rings are arranged on the inner box. Or, the inner wall of an outer box or the outer wall of the inner box is provided with bosses. Thus, after the inner box is put in the outer box, a sandwich layer, which can be injected with refrigerating medium like water or else, is maintained between the two box walls. In freezing, the freezing effect of the medium in the sandwich layer can keep the food in a low temperature state, avoid direct freezing to the food and have good preserving effect. The food taken out of the chilling place can be kept in a freezing and low temperature state for a certain time. The sandwich layer filled with hot water can indirectly heat the food; the sandwich layer filled with cold water can indirectly cool down the food, having easy use.

Description

Laminated food packing box

The utility model relates to a kind of food Package box.

Storing, when transporting food, rotting because of external temperature is higher for preventing food, freezing, cold preserving method commonly used is with food place frost state.When freezing, directly carry out freezing to the food that is added with certain moisture content often.When thawing, the part nutrition of food is then run off with the moisture content after thawing.During dry freeze, then can cause foodstuff surface drying, variable color ageusia.In addition, in temperature higher season, because of the beverage in the existing packing box box and outside air only a box wall every, by the easy heating of beverage of refrigeration place taking-up, and lose the sense of taste of " cold ".

The purpose of this utility model provides a kind of interlayer food Package box, and outer box is built-in with inner box, between the corresponding box wall of outer box and inner box one space interlayer is arranged, and injects refrigerants such as water in the interlayer.Food is put into inner box, and when freezing, freezing by medium in the interlayer makes the freezing low-temperature condition in food place, avoids food is carried out directly freezing.When from refrigeration taking-up food, because the effect of cryogenic media in the interlayer makes food be difficult for heating.

The technical solution of the utility model is, referring to Fig. 1, be provided with one and be used to hold the inner box (1) of food and the outer box (2) that can be placed inner box, inner box (1) is gone up circle pitch of the laps ring (3), because the effect of circle ring (3), make to remain certain space interlayer (4) between each corresponding box wall of inside and outside box, mezzanine space is used to hold refrigerants such as water.Box is provided with the pipe (5) that communicates with mezzanine space outside, is used to inject refrigerants such as water.Except that circle pitch of the laps ring (3) on inner box, can make inside and outside box box wall keep the technical scheme of certain space interlayer to have: see Fig. 3, each interior angle place of box (19) establishes the boss (21) that matches with each angle of inner box (20) outside; Also can interior outer box wall or outside boss rationally is set on the box inwall, the mezzanine space size of this moment then is the height of corresponding boss.

Fig. 1 is a constructional drawing of the present utility model, is appointed as the specification digest accompanying drawing;

Fig. 2 is spherical constructional drawing for the utility model profile;

Fig. 3 is the constructional drawing of embodiment 3.

Below in conjunction with drawings and Examples structure of the present utility model and making, packaging process are elaborated.

Embodiment 1, by structure fabrication shown in Figure 1, becomes rectangular shape, and the food capacity is 0.5 kilogram.Each part is all made with non-toxic plastic.Inside and outside box wall thickness is 1 millimeter, and the box wall is provided with the strip reinforced rib.Inner box (1) earlier by end box (6), go up box (lid) (7) and make respectively, the food box (lid) (7) on end box (6) rear seal-cover of packing into.Be provided with the pipe (8) that communicates with the box chamber on the last box (lid) (7) of present embodiment, be provided with simultaneously, consider that food injects fresh-keeping medium or is used to pack water juice beverage in box this pipe is set for inserting around this effective earrings (9).When being used to pack food bar and not needing to inject fresh-keeping medium again, also can not establish this pipe.Present embodiment is provided with (3) four on circle ring, becomes " well " font circle on inner box, and circle ring junction is recess each other; Circle ring diameter of section is 2.5 millimeters, so that keep the space interlayer between inside and outside box box wall; The circle ring is provided with hole (11), and the medium circulation for injecting in the interlayer makes mezzanine space all can be full of medium everywhere.Outer box (2) is pressed box (12) earlier, top box (lid) (13) is made respectively, establishes pipe (5) on the top box (lid) and supplies the slotting earrings (10) around usefulness of this pipe.The inner box that food is housed is inserted down box (12) rear seal-cover top box (lid) (13).Inject medium such as water by pipe (5) after, carry out freezing, tube sealing mouth, but also freezing again behind the tube sealing mouth.Box (12) mezzanine space water filling downwards in the ban, capping again, when freezing, the pipe (5) of this moment can not be provided with, but top box in such cases (lid) (13) can be designed to a cover plate.

Embodiment 2, press Fig. 2 structure fabrication, glomeration.Inner box (14) is pressed box (15), and middle box (16), last box (17) are made respectively, will play box and middle box involution earlier, adorn food then, again box (17) in the capping.Inner box (14) is gone up circle around three circle rings, so that keep the certain space interlayer between inside and outside box box wall.The making of the outer box (18) of present embodiment, same inner box (14) press, in, last three make and capping successively.Outer box (18) also can be by upper and lower hemispherical structure fabrication, capping.Other are with embodiment 1.

Embodiment 3, press Fig. 3 structure fabrication, and this embodiment does not establish circle ring, and each interior angle place of box (19) establishes the boss (21) that matches with each angle of inner box outside, and boss guarantees space interlayer between inside and outside box box wall with this for high 3 millimeters, and other are with embodiment 1.Boss also can be arranged on the inner box (20).

The utility model in addition to the implementation, shape such as that its profile also can be made into is cylindrical, rectangle, material can be sheet metal etc.

That the utility model is used for is freezing, during chilled food, freezing by medium in the interlayer makes the freezing low-temperature condition in food place in the box, avoids food is carried out directly freezing, can not lose food nutrition, has good fresh-keeping effect. In addition, when food is taken out by refrigeration place, can make again food locate within a certain period of time freezing low-temperature condition, effective. Also can be by injecting hot water to mezzanine space, the food indirect will cool; By injecting cold water to mezzanine space, food is lowered the temperature indirectly. Easy to use.
