Thermal food container and relative method of manufacture

Abstract

The invention provides a thermal food container (4) and a relative method of manufacture. The thermal food container (4) comprises an outer body (8), at least two trays (12) for containing foods, said trays (12) being separated from each other and being contained inside the outer body (8), an outer closure lid (16) detachably associable with the outer body (8), a thermally insulating element (14) positioned between the trays (12) and the outer body (8). Advantageously, the trays (12) are over moulded with a joining ring (20) which joins them to each other, keeping them separate at the point of at least one separation septum (24). Furthermore, the joining ring (20), joining the trays (12), is welded and / or glued to the outer body (8) after interposition of said insulating element (14), so as to form a hermetic joint between the joining ring (20) and the outer body (8).

Description

technical field [0001] The present invention relates to heat-retaining food containers and related manufacturing methods. Background technique [0002] It is known in the art that thermal containers, especially for food, have at least one heat-insulated tray in order to store the food inside while keeping its temperature as constant as possible. [0003] The prior art solutions have a number of disadvantages. [0004] For example, prior art containers do not allow the efficient storage of food products at different temperatures within clearly separated interior compartments. [0005] In other words, known containers comprise a single internal food-holding and storage compartment; there are also solutions for containers with two food-holding compartments separated from each other: however said compartments cannot be effectively isolated from each other, and thus Storing food at different temperatures (for example, hot and cold food) to maintain said temperature differential...

Problems solved by technology

[0005] In other words, known containers comprise a single internal food-holding and storage compartment; there are also solutions for containers with two food-holding compartments separated from each other: however said compartments cannot be effectively isolated from each other, and thus Storing food at different temperatures (for example, hot and cold food) is not allowed to maintain said temperature difference over time

[0006] Furthermore, the solutions of the prior art, even if achieved to ensure sufficient thermal insulation between the trays or the inner containment compartments, do not allow the trays to be completely washed, for example in a dishwasher, considering that the trays are not hermetically sealed. container

As a result, water penetration, e.g. after washing in the dishwasher or e.g. in the sink, sooner or later leads to bacterial growth and ultimately damage to the inner lining between the inner tray and the outer body of the container

[0007] In addition, the container structure of the prior art is complicated and the manufacturing cost is high
