DOUBLE WALLED CONTAINER

Abstract

A double-walled container is used to thermally isolate a stored substance from the external environment. The double walled container has an interior container, an exterior sidewall a flat base and a spacer ring. The interior container serves as a receptacle into which the stored substance is placed. The exterior sidewall is mounted onto the flat base so that the double walled container can be rested on a surface. The spacer ring is connected in between a rim of the exterior wall and a rim of the interior container. Thus connected, the spacer ring maintains the interior container in a position offset from the exterior sidewall. This enables an insulating compartment to be positioned in between the two components. Thereby, thermally isolating the interior container from the exterior sidewall.

FIELD OF THE INVENTION

The present invention relates generally to a container. More specifically, the present invention relates to a thermally insulated container.

BACKGROUND OF THE INVENTION

Transporting hot food is often a challenge. Frequently, a user is forced to use potholders when moving a container filled with hot food from place to place. Foregoing the use of potholders often results in spilled food or even burned hands. This issue can waste food and may lead to hospitalization.

The present invention, a double walled container, addresses this issue by providing a container that thermally isolate the hot food from the container's exterior surface. Thus, reducing the chance that the user will be burned or forced into an uncomfortable position. To achieve this functionality, the present invention employs a multicomponent container that separates an internal receptacle from an exterior sidewall via an airgap. This air gap prevents the heat from the food stored within the interior receptacle from burning the hands of the user. Similarly, the present invention is designed to prevent cold substances stored within the interior receptacle from dropping the temperature of the exterior sidewall and causing tissue damage.

Referring to FIG. 1 through FIG. 4, the preferred embodiment of the present invention, a double walled container, is designed to act as an insulated receptacle for foods, fluids, and other substances. The present invention enables a user to transport hot or cold substances without fear of being burned or frozen. To achieve the above described functionality, the present invention comprises an interior container 1, an exterior sidewall 2, a flat base 3, and an annular spacer 4. The exterior sidewall 2 forms the outermost layer of the present invention and comprises a wall body 21 and an exterior rim 22. The interior container 1 is designed to act as the storage receptacle for the substance placed into the present invention. Preferably, the present invention functions as a bowl. However, embodiments of the present invention are fashioned into a device selected from the group including, but not limited to, cups, mugs, pitchers, and thermoses. The annular spacer 4 is perimetrically connected around an upper rim 11 of the interior container 1 and extends away from the upper rim 11. Additionally, the annular spacer 4 is connected in between the exterior rim 22 of the exterior sidewall 2 and the upper rim 11 of the interior container 1. Thus positioned, the annular spacer 4 retains the interior container 1 in a desired position. Specifically, the annular spacer 4 retains the interior container 1 in a position where the exterior sidewall 2 encompasses the interior container 1. This configuration facilitates insulating an exterior environment from the substance stored within the interior container 1. The wall body 21 is a rigid panel that forms the structural component of the external sidewall and defines the external sidewall's overall shape. The wall body 21 is connected in between the exterior rim 22 and the flat base 3. Additionally, the wall body 21 is terminally and perimetrically connected around the flat base 3. As a result, the wall body 21 support the weight of the interior container 1 while the flat base 3 is resting on an external surface. An insulating compartment 5 is positioned in between the interior container 1 and the exterior wall. Consequently, the insulating compartment 5 thermally isolates the interior container 1 from the exterior sidewall 2.

Referring to FIG. 2 and FIG. 3, the interior container 1 is designed to act as a storage receptacle for substances. To facilitate this functionality, the interior container 1 comprises a container sidewall 12, a container base 13, and a receptacle 14. The container sidewall 12 is connected in between the upper rim 11 and the container base 13. Thus, forming a structure that supports the weight of the stored substance. Further, the container sidewall 12 and the container base 13 delineate the receptacle 14. Thereby, defining the overall shape and volume of the interior container 1. In some embodiments, the interior container 1 further comprises an insulating liner 15. The insulating liner 15 is a film of material that is superimposed onto the container sidewall 12 opposite to the insulating compartment 5, across the container sidewall 12. This film further facilitates thermally isolating the interior container 1 from the exterior sidewall 2. Preferably, a transverse cross-section of the container sidewall 12 curves from the container base 13 to the upper rim 11. Likewise, a transverse cross-section of the wall body 21 curves from the flat base 3 to the exterior rim 22 Thus, defining a hemispherical shaped device. Preferably, a radius 16 of the exterior rim 22 is greater than a radius 23 of the upper rim 11. Accordingly, the exterior sidewall 2 is positioned offset from the interior container 1. Some embodiments of the present invention feature interior containers 1 with a geometry that does not mirror a geometry of the exterior sidewall 2. For example, the interior container 1 may be shaped in a geometry selected from the group including, but not limited to, conical, cylindrical, or cuboid.

Referring to FIG. 2, the annular spacer 4 is designed to retain the interior container 1 in a position offset from the exterior sidewall 2. In some embodiments, the annular spacer 4 creates a rounded edge and comprises a first leg 41, a second leg 42, and an intermediary leg 43. The first leg 41 is connected in between the upper rim 11 and the intermediary leg 43. Additionally, the second leg 42 is connected in between the exterior rim 22 and the intermediary leg 43. Consequently, the annular spacer 4 provides an edge-free transition between the interior container 1 and the exterior sidewall 2. In some embodiments, the annular spacer 4 is a flat panel that is connected in between the upper rim 11 and the exterior rim 22.

Referring to FIG. 1, some embodiments of the present invention are designed with an insulating substance 6 that fills the insulating compartment 5. Preferably, the insulating substance 6 is air. The insulating substance 6 facilitates thermally isolating the interior container 1 from the exterior sidewall 2. In further embodiments, the insulating compartment 5 is evacuated to thermally isolate the interior container 1 from the exterior sidewall 2. Supplemental embodiments include a solid insulation material that is housed within the insulating compartment 5. Embodiments of the present invention are constructed using insulating materials that do not conduct heat. Thereby, preventing heat from being transferred out of the stored substance, through the interior container 1, the annular spacer 4, and into the exterior sidewall 2.

Referring to FIG. 1 through FIG. 3, as described above, the present invention is designed to function as a bowl for transporting food and other substances. To that end, the present invention further comprises a textured liner 7. The textured liner 7 is a friction increasing film that is superimposed onto the exterior sidewall 2 opposite to the insulating compartment 5, across the wall body 21. As a result, the textured liner 7 prevents the present invention from slipping out of a user's hand while being transported. In some embodiments, the textured liner 7 is a surface structure selected from the group including, but not limited to, knurling, ribbing, and a plurality of protrusions. In further embodiments, the textured liner 7 is a rubberized material that facilitates gripping the exterior sidewall 2. Preferably, the exterior sidewall 2 and the interior container 1 are composed of transparent materials. Thus, enabling the user to visually inspect the contents of the interior container 1.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
