Description

FIELD OF THE INVENTION

The present invention relates to a cold insulation container, and more particularly to a cold insulation container having a cover provided with a separated refrigerating element storing space.

BACKGROUND OF THE INVENTION

A conventional cold insulation container is designed to temporarily store goods or foods at a low temperature. The cold insulation container is then delivered to a customer or a market with the goods or foods kept in a fresh state. In the conventional cold insulation container, cold storage means are placed atop the stored goods or foods. When it is desired to access the stored goods or foods, the cold storage means must be moved away first. It is of course inconvenient for a user to do so. In the case dry ice is used as a cold storage material for use in the cold insulation container, a dry ice tray is placed in the container above the goods or foods for holding the dry ice thereon. Similarly, to access the stored goods or foods, the dry ice tray must be inconveniently moved away first. Meanwhile, no matter the cold storage means are provided at an upper part or at one side in the container, the cold storage means must be cleaned before being frozen for next use, so as to avoid condensed water from accumulating and becoming frozen on the cold storage means. Without doing so, stored goods or foods are subject to contamination by molten condensed water from the cold storage means.
Another type of conventional cold insulation container has a cover with a secondary lid. The cover internally provides a small space for holding money, knives, notebooks, etc., which may be accessed via the secondary lid. Or, the secondary lid on the cover is only for openably closing a small opening on the cover. Goods stored in the container, such as canned beverage, can be directly accessed via the small opening without the need of opening the whole cover. However, the secondary lid for such small opening generally does not include any heat insulation design and accordingly, will adversely affect the cold insulation performance of the container.
In some cases, dry ice is placed in a coffin to achieve the purpose of temporarily lowering the temperature in the coffin. Since the coffin is not provided with any power-driven refrigerating system, a large quantity of expensive dry ice is consumed to keep the coffin at the low temperature, particularly when there is a body stored therein. The cover of the coffin must be opened each time the dry ice is positioned or replaced. This would no doubt bring confusions to the workers and the family. There is another type of coffin having an electrical refrigerating system integrated thereinto. When operating, the electrical refrigerating system will dissipate heat and produce noise. In addition, the electric refrigerating system for the coffin requires wiring to a power supply.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide a cold insulation container having a cover provided with a separated refrigerating element storing space, which is openably closed by a secondary lid on the cover for holding refrigerating elements therein, and goods requiring cold insulation are stored in another closed space in the container below the cover. With the goods and the refrigerating elements positioned in two separate spaces, the stored goods are not subject to contamination by condensed water from the refrigerating elements.
To achieve the above and other objects, the cold insulation container of the present invention includes a heat-insulating container body and a heat-insulating cover pivotally connected to and openably closing the container body to define a closed space in the container for storing goods therein. The cover includes a base defining an open-topped recess and a secondary lid pivotally connected to the base to openably close the recess. A plurality of vents is provided at the recess. The cold insulation container further includes at least one refrigerating element disposed in the recess on the cover.
In the present invention, the heat-insulating container body and the heat-insulating cover are made of a vacuum-insulated material or a foamed insulating material, such as PU, PS, EPP, etc., to maintain the closed space in the container at a required low temperature.
In an embodiment of the present invention, the recess on the cover may further include a refrigerating element tray. The refrigerating element tray is made of a metal material to help in cooling the closed space of the container. The refrigerating element tray may be otherwise made of a plastic material.
The refrigerating element tray may be integrally formed with the recess, or separately formed for detachably connecting to the recess for easy dismounting and cleaning of the tray.
In the present invention, the vents may be formed at a peripheral wall or a bottom of the refrigerating element tray. Cold air in the recess can descend via the vents to the closed space in the container body. In addition, the bottom of the refrigerating element tray has an uneven surface or is provided with a plurality of elongated protrusions to provide an increased surface area to help in heat exchange in the container.
In the present invention, the refrigerating element is a cold storage means, a phase change energy storage material, or dry ice.
The cold insulation container of the present invention is used to deliver and store goods of various storage temperature levels.
