Abstract
The utility model relates to a food container capable of being heated by microwave oven. The box body comprises metal foil and polypropylene films combined on two sides of the metal foil. The thickness of the metal foil is 0.08-0.25 mm; the thickness of the polypropylene film is 0.03-0.08 mm. The experiment proves that when the box body of the food container capable of being heated by microwave oven is filled with water or other food and the box body is placed in the common domestic microwave oven to be heated for 5-20 minutes, the food in the box body are normally heated, the box body have no damage, and non peculiar smell diffuses. As is well known, the heating time for the common box food with the microwave ove is not more than 20 minutes, and thus the utility model can heat food in the microwave oven, which brings great convenience for consumers.
Description
Technical field
The utility model relates to a kind of food containers, particularly a kind of food containers of available micro-wave oven heating.
Background technology
The existing packing material (as the metallic paper food containers) that has metal level heats so generally can not put into micro-wave oven owing to can produce current vortex therein under the effect of microwave, and this makes troubles to the customer.
Summary of the invention
The purpose of this utility model just provides a kind of metallic paper food containers of available micro-wave oven heating, and existingly have the micro-wave oven of can not putting into that metal level (as metallic paper) food containers exists and heat to solve, thus the problem of making troubles to the customer.
The technical solution of the utility model is: described box body is made of metallic paper and the polypropylene film that is compounded in its both sides; The thickness of described metallic paper is 0.08～0.25mm, and the thickness of described polypropylene film is 0.03～0.08mm.
Described metallic paper is an aluminium foil, and its thickness is 0.08～0.20mm.
Described metallic paper is a tin-plate, and its thickness is 0.15～0.25mm.
Water or other food are injected in evidence in the utility model box body, put into the normal domestic use micro-wave oven and heated 1～20 minute, and the article in the box are by normal heating, and any damage does not appear in box body, and also free from extraneous odour overflows.As everyone knows, general boxed food can not surpass 20 minutes with the micro-wave oven heating is general each, thus the utility model can be in micro-wave oven heated food, greatly facilitate the customer.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is the generalized section of box body of the present utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises by at the bottom of the box and the box body 1 formed of box group, is provided with crimping 2 at the edge of this box group, helps at the box of this box body and is provided with reinforcement convex-concave rib 3.
Referring to Fig. 2, described box body 1 by metallic paper 5 and be compounded in the polypropylene film 4 of its both sides and 6 three layers constitute.This three-decker all adopts the composite material of food stage digestion resistant, forms by the manufacturing of metallic paper container formation technology.
It is the aluminium foil of 0.08～0.20mm that described metallic paper 5 can adopt thickness.It is 0.15～0.25mm tin-plate sheet that metallic paper 5 also can adopt thickness.Described polypropylene screen 4 and 6 thickness are 0.03～0.08mm.
The test that the utility model process is a large amount of, the one, any article are not placed in the sylphon test in box body, put into the normal domestic use micro-wave oven and continue heating 1～20 minute.Box body has only low-grade fever after heating, do not have peculiar smell to produce.
Another test is to inject water or other food in the utility model box body, uncovered or cover the non-metal lid and put into micro-wave oven and continue heating 1～20 minute, article in the box are by normal heating (comparing with the food that is placed in the micro-wave oven special container), and any damage does not appear in box body, and also free from extraneous odour overflows.
As everyone knows, general boxed food can not surpass 20 minutes with the micro-wave oven heating is general each, thus the utility model can be in micro-wave oven heated food, greatly facilitate the customer.
From above-mentioned test results as can be seen, this structure does not have owing to the microwave eddy current destroys box body structure or causes the localized hyperthermia of box body to emit gas with foreign flavor.Can go out possible reason according to structure characteristic analysis, promptly because the very thin thickness of metallic paper, its both sides are closely compound with polypropylene film again, a large amount of free electrons in the metallic paper are attracted constraint by the surface charge of its surperficial polypropylene film, reduce the quantity of free electron and the distance of cross motion, this has just weakened the energy of eddy current greatly.And microwave energy enters in the box body from the opening part of container, realizes the purpose to food heating in the box body.
