Abstract

A food material container keeping the temperature inside the container the same as that outside the container has a preset container shape made of material such as plastic by means of injecting molding process. Each wall of the container is formed with many layers of uncountable slender strings having uncountable irregular circles, separated from one another and entangling with one another to form solid. Thus the container has uncountable micro air cells communicating with one another so that air or liquid outside and inside the container flow mutually and smoothly without any dead spot and having a buffering function against food material stored in the container.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This inventin relates to a food material container, particularly to one provided with uncountable micro air cells in walls of the container, enabling exterior air to flow through them into the interior smoothly, keeping food material put therein to be well ventilated and not to get worse.
  • 2. Description of the Prior Art
  • A conventional food material container shown in FIG. 1 used for holding refrigerated food material is made of plastic and shaped in a preset case shape 1 by injecting molding process, with many through holes 2 formed in each wall of the case 1, and the through holes 2 are for air to flow through from the exterior into the interior of the case 1 for ventilating the contents of the conventional container.
  • However, the through holes 2 are all on the same level of the surface so that if the food material placed in the conventional container has a size larger than that of each through hole 2, the food material may become rotten soon because of bad ventilation and the interior temperature of the container rising up higher than that of the exterior of the container, as the through holes 2 are all completely closed by the food material.
  • Moreover, the through holes 2 are obliged to be spaced apart with a certain distance for enabling the conventional container possess a certain strength for holding food material, and the ventilation of air through the through holes may be reduced largely by food material, which can easily contact with the inner surface of the walls of the conventional container and clog the through holes nearly completely.
  • SUMMARY OF THE INVENTION
  • This invention has been devised to offer a food material container, which is made of plastic to form a rectangular, square or round case with vertical walls, a bottom wall and an open upper side. The plastic may be PE (polyethylene), PP (polypropylene), ABC (acrylonitrile butadiene styrene) or PC (polycarbonate) hygienically suitable for food. Each wall is made of innumerable slender strings of the plastic through injecting molding process, and the slender strings have many irregular tiny circles entangled with one another and forming uncountable micro air cells communicating with one another so that the whole container is extremely ventilating to keep the temperature of the interior almost the same as that of the exterior of the container even food material is fully placed therein.
  • BRIEF DESCRIPTION OF DRAWINGS
  • This invention will be better understood by referring to the accompanying drawings, wherein:
  • FIG. 1 is a perspective view of a conventional food material container;
  • FIG. 2 is a perspective view of a food material container in the present invention; and,
  • FIG. 3 is a cross-sectional view of a partial wall of the food material container in the present invention.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • A preferred embodiment of a food material container in the present invention, as shown in FIGS. 2 and 3, is formed in a preset shape of a rectangular case consisting of four vertical walls. a bottom wall and an open upper side, or of a square or round case made of basic material 10 such as PE, PP, ABS or PC hygienically usable for keeping food material. Each wall is composed of plural layers of uncountable slender strings 11 having uncountable micro irregular circles to entangle with one another, so innumerable micro air cells 12 are formed in each wall for air or liquid to flow fast from the exterior into the interior of the container, with the many layers of the slender strings 11 making up a certain thickness of basic material 10 (or each wall).
  • As shown in FIGS. 2 and 3, each wall of the food material container has the uncountable micro air cells 12 formed by the irregular micro circles of the slender strings 11 of plastic, and the micro air cells 12 are communicating with one another. So the slender strings 11 may contact with food material placed in the food material container in very small dimensions to let it very ventilating. Therefore, if the food material container is stored in an environment under the room temperature or in a refrigerated room, the temperature in the interior of the food material container filled with food material may be maintained the same as the exterior of the container. Further the basic material 10 has the property in compliance with keeping food material, and then the food material container in the invention can be used for various kinds of food materials, and the micro air cells 12 cannot be clogged by food material, no matter how large or small the food material may be.
  • The invention has the following advantages as can be seen from the foresaid description.
  • 1. It has uncountable irregular micro air cells to make up good ventilation so food material placed therein can be prevented from damaged owing to bad ventilation or accidental shocks.
  • 2. Each wall of the food material container has innumerable slender strings made of plastic, and the slender strings only have a very small dimension to contact with food material, not causing bad ventilation of the container, and then food material therein may not be damaged easily.
  • 3. It is made of plastic such as PE, PP, ABS or PC so it is easily manufactured to have any integral shape wanted by injecting molding process.
  • While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.

Claims (3)

1. A food material container keeping the temperature of food material stored therein as the same as that of the exterior of said container, said container comprising:
