Abstract
The present invention provides a heat-insulated container made of an environment-protection material to contain food in a main body of the container while keeping temperature of the food.
Description
- The present invention relates to a heat-insulated container; more particularly, relates to containing food in a main body to keep temperature of the food while being environment-protecting.
- A
general container 4 can be a meal box, a cup, etc. to contain food. As shown inFIG. 9 , take a meal box for example. Thecontainer 4 comprises a containingpart 41 and acover 42 located at a side of thecontainer 4 to seal an opening of the containingpart 41 Thus, food can be contained in the containingpart 41 and be sealed in the containingpart 41 with the cover. - Although the food can be kept in the
container 4, thecontainer 4 is usually made of a poly foam or a waterproof paper which is not well conformed with actual needs. Poly foam is made of polystyrene or polyvinyl chloride which is not degradable; besides, PCDD (polychlorinated dibenzo-p-dioxins) will be produced when it is burned and may cause serious harm to human body and environment, which is so limited on usage by law. The waterproof paper prevents the disadvantages of the poly foam; yet its capabilities on heat insulation and warmth keeping is not good. When a hot food is contained in acontainer 4 made of the waterproof paper, human hand can be scalded once the hot food is being put in thecontainer 4; yet the hot food will lose heat and be cooled down in a short time afterwards. Hence, the prior arts do not fulfill users'requests on actual use. - The main purpose of the present invention is to contain food in a main body while being heat-insulated to keep temperature of the food.
- To achieve the above purpose, the present invention is a heat-insulated environment-protection container, where the container comprises a main body, which is comprised of a substrate and a coating layer, and the main body has a containing part; and, an inner heat-insulating layer is foamed in the containing part by using the material of the coating layer. Accordingly, a novel heat-insulated environment-protection container is obtained.
- The present invention will be better understood from the following detailed descriptions of the preferred embodiments according to the present invention, taken in conjunction with the accompanying drawings, in which
-
FIG. 1 is a perspective view showing a first preferred embodiment according to the present invention; -
FIG. 2 is a sectional view showing the first preferred embodiment according to the present invention; -
FIG. 3 is a perspective view showing a second preferred embodiment according to the present invention; -
FIG. 4 is a perspective view showing a third preferred embodiment according to the present invention; -
FIG. 5 is a view showing a state of use of the first preferred embodiment according to the present invention; -
FIG. 6 is a sectional view showing a fourth preferred embodiment according to the present invention; -
FIG. 7 is a view showing a state of use of a fifth preferred embodiment according to the present invention; -
FIG. 8 is a view showing a state of use of a sixth preferred embodiment according to the present invention; -
FIG. 9 is a perspective view of a prior art. - The following descriptions of the preferred embodiments are provided to understand the features and the structures of the present invention.
- Please refer to
FIG. 1 andFIG. 2 , which are a perspective view and a sectional view showing a first preferred embodiment according to the present invention. As shown in the figures, the present invention is a heat-insulated environment-protection container, comprising amain body 1 and an inner heat-insulating layer, where themain body 1 is heat-insulated by the inner heat-insulatinglayer 2 to contain food. - The
main body 1 comprises asubstrate 11 and acoating layer 12 deposed on outside surface of thesubstrate 11. Thesubstrate 11 is made of a waterproof paper; and thecoating layer 12 is made of a low density polyethylene. Themain bosy 1 comprises a containingpart 13. - The inner heat-insulating
layer 2 is foamed by using the material of thecoating layer 12 and is deposed in the containingpart 13. The inner heat-insulatinglayer 2 is made of a chemical-synthesized biodegradable material of a polylactic acid, a polycaprolactone or an a aliphatic compound; or a biodegradable material of a microorganism fermentation of PHA or PHB. The inner heat-insulatinglayer 2 comprises a plurality ofbubbles 21 on inner surface of the inner heat-insulatinglayer 2. Thus, a novel heat-insulated environment-protection container is obtained. - Please refer to
FIG. 3 throughFIG. 5 , which are perspective views showing a second preferred embodiment and a third preferred embodiment and a view showing a state of use of the first embodiment, according to the present invention. As shown in the present invention, when using the present invention, a meal box (as shown inFIG. 1 ), a cup (as shown inFIG. 3 ) or a Pizza box (as shown inFIG. 4 ) with amain body 1 can be made according to the requirement to containfood 3 in themain body print area 14 is located on outside surface of themain body - Take the meal box for example. When using the present invention,
food 3 is contained in the containingpart 13 of themain body 1; and themain body 1 is covered by acover 15 to seal thefood 3 in themain body 1. By doing so, thefood 3 contained in themain body 1 is heat-insulated by the inner heat-insulatinglayer 2. In addition, the inner heat-insulatinglayer 2 is made by a foaming to obtain light-weight and low cost while comprising a self-degration in nature (conformed with Taiwan's National Standard, CNS14432, Method for determination of the ultimate aerobic biodegradability and disintegration of plastic materials under controlled composting conditions—Method for Analysis of evolved carbon dioxide) to cause no harm to environment or being recycled for a degration into compost (conformed with Taiwan's National Standard, CNS146611, Method for determination of compostable plastics) to enhance economic benefits of the container. - Please refer to
FIG. 6 , which is a sectional view showing a fourth preferred embodiment according to the present invention. As shown in the figure, not only an inner heat-insulatinglayer 2 is deposed in a containingpart 13 of amain body 1, but also an outer heat-insulatinglayer 2 a, obtained by foaming with the material of acoating layer 12, is deposed on outside surface of themain body 1; thus, the main body is biodegradable, warmth-keeping and heat-insulated. Regarding amain body 1 a (as shown inFIG. 3 ) of a cup to contain hot drink, a temperature in the containingpart 13 is kept by the inner heat-insulatinglayer 2 and a scald to the palm is prevented by the outer heat-insulatinglayer 2 a. - Please refer to
FIG. 7 andFIG. 8 , which are views showing a state of use of a fifth and a sixth preferred embodiments according to the present invention. As shown in the figures, the present invention is used to contain an ice product 31 or afresh food 32 in amain body 1 c, 1 d, which means that the present invention can be used to contain food to prevent heat from transferring. When storing a hot food, the present invention prevents heat of the food from transferring out to the outside; and, when storing a cool or cold food, the present invention prevents heat of the outside from transferring in to the food. - To sum up, the present invention is a heat-insulated environment-protection container, where a containing part of a main body is heat-insulated by using an inner heat-insulating layer in the containing part when containing food to keep the temperature of the food.
- The preferred embodiments herein disclosed are not intended to unnecessarily limit the scope of the invention. Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
