Description

The lunch box be made up of PP plastics

Technical field

The utility model relates to a kind of lunch box, and more particularly, it relates to a kind of lunch box be made up of PP plastics.

Background technology

In recent years disposable on market fast foodbox turns to environmental protection lunch box by foam food boxes, and foam food boxes are originally due to non-refractory, and manufacturing process damages environment and enjoys superseded, get and treat have plastic lunch box, paper made lunch box, wooden lunch box, degraded lunch box ... etc..Wherein, the plastics features such as toxicity is lower, fusing point is higher, plasticity is strong owing to having, it is easy to produce and relative cost is lower, because having formed the mainstay material manufacturing disposable snack box.As PP plastic lunch box, PP refers to polypropylene, has fabulous mechanical performance and hot property, is particularly suitable for the packaging applications heating food.And PS polystyrene, firm and crisp, nontoxic, tasteless, be particularly suitable for Frozen Food Packaging as cake or salad etc.

So, make disposable lunch box by PP plastics and there is good hot property, the food materials in direct lunch box capable of heating in micro-wave oven can be placed on.

At present, there is lunch box on the market that hold soup specially, and undertaken heating to soup by micro-wave oven.But usually have residue in soup, after edible soup, residue is not easy to cleaning, comparatively inconvenience.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide one can heat in micro-wave oven, and can hold soup and collect the lunch box be made up of PP plastics of residue.

For achieving the above object, the utility model provides following technical scheme:

A kind of lunch box be made up of PP plastics, comprise inner box and outter box, described inner box has the inner chamber holding soup, and the outward flange of described inner box has the first buckling parts, described outter box has the exocoel holding described inner box, have the second buckling parts engaging described first buckling parts at the inward flange of described exocoel, described inner box is after the second buckling parts and the engaging of the first buckling parts, and described in shutoff, the part of exocoel is uncovered.

Preferably, after described first buckling parts engages with the second buckling parts, described inner box is suspended in described exocoel.

Preferably, described outter box is covered with lid.

Preferably, have the first card lip at the outward flange of described outter box, the edge of described lid has the second card lip of closely engaging the first card lip.

Preferably, the bottom of described lid has the portion of covering, described in cover portion after outter box and lid cover, inner chamber described in shutoff uncovered.

Compared with prior art, inner box of the present utility model is in order to hold soup, and when inner box is placed on exocoel, exocoel still has uncovered not by shutoff of part, in order to receive soup residue, and health, convenience more.

Detailed description of the invention

Referring to figs. 1 through Fig. 6, the lunch box embodiment that the utility model is made up of PP plastics is described further.

Disclose a kind of lunch box be made up of PP plastics in fig. 1 and 2, it can be placed in micro-wave oven edible.Food materials are placed in bowl-shape inner box 2 specifically, then inner box 2 is placed in outter box 1;

Narrow gradually to two ends at the uncovered middle part by its circle of outter box 1.Be provided with the recessed spine 11 of indent at the inward flange at the uncovered middle part of outter box 1, establish by the convex ridge portion 21 fastening recessed spine 11 at the outward flange of inner box 2.

So, when using the food materials in inner box 2, inner box 2 can be taken out, hold food materials with inner box 2, unexpected box body 1 holds food materials residue;

Or, because inner box 2 is comparatively hot after microwave-oven-heating, now without the need to taking out inner box 2, the food materials directly in edible inner box 2, and food materials residue is collected in by the two ends that outter box 1 is uncovered in the remaining space of outter box 1, very convenient.

In addition, the present embodiment is in order to expand the scope of application of lunch box further.The inner box 2 of the present embodiment is coordinating by its convex ridge portion 21 and recessed spine 11, is suspended in outter box 1.So designed by said structure, make inner box 2 when being placed on the exocoel of outter box 1, the two ends of exocoel can be interconnected, the food materials residue entered by the uncovered two ends of outter box 1 will be flocked together, prevent the uncovered one end of outter box 1 from filling up food materials residue, and the phenomenon that the other end is still vacant.

The outter box 1 of the present embodiment is covered with box body.So that carry.

Preferably, be provided with the first outwardly card lip 12 at the outward flange of outter box 1, be provided with the second card lip 31 engaged with the first card lip 12 at the outward flange of lid 3.First card lip 12, when being close to the second card lip 31, forming stepped sealed of opposite outer, effectively enhances the air-tightness of lunch box.

In addition, be provided with in the bottom of lid 3 and cover round platform 32, when lid 3 covers with outter box 1, cover the uncovered of round platform 32 shutoff inner box 2.Ensure also can keep sealing between outter box 1 and inner box 2, prevent the food materials in inner box 2 from falling into outter box 1, be easy to carry.

It is worth mentioning that, the round platform 32 that covers of the present embodiment can be made up of rubber elastomeric material, so that when covering the bowl-shape inner box 2 of round platform 32 shutoff, strengthen sealing effectiveness further.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
