Before the various embodiments of the present invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that phraseology and terminology used herein with reference to device or element orientation (such as, for example, terms like “front”, “back”, “up”, “down”, “top”, “bottom”, and the like) are only used to simplify description of the present invention, and do not alone indicate or imply that the device or element referred to must have a particular orientation. In addition, terms such as “first”, “second”, and “third” are used herein and in the appended claims for purposes of description and are not intended to indicate or imply relative importance or significance. As used herein, the term “rectangle” is meant to include any quadrilateral having four right angles.
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 provide a perspective view of a first embodiment of the container protector 10 engaged with a container 20. The embodiment of the container protector 10 shown in FIG. 1 is configured to engage a container 20 that is rectangular in shape. Such containers 20 typically include two opposing container side walls 22 connected to two opposing container end walls 24 in one integral structure. Container handles 24a may be fashioned in the container end walls 24 to facilitate repositioning of the container 20 during use or otherwise moving the container 20.
The first embodiment of the container protector 10 includes two opposing side skirts 32 configured to seal against the container side walls 22. Two opposing end skirts 34 are configured to seal against the container end walls 34. The side skirts 32 are affixed to the end skirts 34 so that the shape of the container protector 10 is substantially the same as the shape of the container 20. Handle extensions 34a may be included in the end skirts 34 to seal against the container handle 24a in containers 20 that are configured with container handles 24a. However, container protectors 10 configured for use with containers 20 not having container handles 24a may be constructed without handle extensions 34a. 
It is contemplated that the container protector 10 will be constructed of a pliable and/or semi-pliable material and configured so that the container protector 10 stretches by a certain amount when engaged with the container 20, thereby creating a hermetic seal between the container 20 and the container protector 10. That is, the elastic or semi-elastic nature of the container protector 10 allows it to expand so that it is secured to the container 20. Accordingly, in many applications the periphery of the container protector 10 will be less than the periphery of the container 20 for which it is designed. During use, attachment of the container protector 10 to the container 20 will require the user to stretch the container protector 10 over the container 20, thereby ensuring the container protector 10 is adequately secured to the container 20 and that an adequate seal is created between the container protector 10 and container 20.
An interior lip 30 may be connected to both the opposing side skirts 32 and the opposing end skirts 34. The interior lip 30 is configured to extend inward from the periphery of the container 20, which is best shown in FIGS. 1A and 1B, which provide different cross-sectional views of the container protector 10 engaged with a container 20.
A cross-sectional view of a portion of the container protector 10 and container 20 adjacent a container handle 24a and a handle extension 34a is shown in FIG. 1A. A cross-sectional view of a portion of the container protector 10 and container 20 along a container side wall 22 and side skirt 32 is shown in FIG. 1B. As shown in these various figures, the interior lip 30 extends upward beyond the periphery of the container 20 and inward therefrom. This extension of the interior lip 30 combined with the sealing engagement between the end skirts 34 and container end walls 24, the handle extensions 34a and container handles 24a, and the side skirts 32 and container side walls 22 serves to functionally increase the volume of the container 20. Accordingly, if material is positioned in the container 20 and the container 20 is subsequently heated, which may expand the material in the container 20, the container protector 10 may prevent the material from flowing out of the container 20. One example of such a situation is during cooking, especially baking scenarios. It is contemplated that the first embodiment of the container protector 10 will be sized to seal a nine-inch-by-thirteen-inch, seven-inch-by-eleven-inch, or other rectangular-shaped container 20. The container 20 may or may not include container handles 24a, and the container protector 10 may be formed accordingly (i.e., with or without handle extensions 34a).
A second embodiment of the container protector 10 is shown in FIG. 2, wherein the container protector 10 is configured to seal against a square-shaped container 20. The container protector 10 in the second embodiment functions identically to that of the first embodiment. However, in the second embodiment of the container protector 10 the container protector 10 is sized to seal an eight-inch-by-eight-inch, nine-inch-by-nine-inch, or other square-shaped container 20. As with the first embodiment, in the second embodiment the container 20 may or may not include container handles 24a, and the container protector 10 may be formed accordingly (i.e., with or without handle extensions 34a).
A third embodiment of the container protector 10 is shown in FIG. 3, wherein the container protector 10 is configured to seal against a circular-shaped container 20. The container protector 10 in the third embodiment functions identically to that of the first and second embodiments. However, in the third embodiment of the container protector 10 the container protector 10 is sized to seal circular-shaped container 20. As with the first and second embodiments, in the third embodiment the container 20 may or may not include container handles 24a, and the container protector 10 may be formed accordingly (i.e., with or without handle extensions 34a).
A container protector with bottom 40 is shown in FIG. 4. The container protector with bottom 40 functions identically to the other embodiments of the container protector 10 disclosed herein. However, the container protector with bottom 40 includes a bottom portion 38 connecting the side skirts 32 and end skirts 34 so that the container protector with bottom 40 forms a type of vessel with substantially the same shape as the container 20 for which the container protector 10 is designed. The bottom portion 38 may be configured to either allow for or inhibit accumulation of baked-on materials between the container protector with bottom 40 and the container 20, thereby enhancing removal of food particles after use.
As is apparent in light of the present disclosure, when the container protector 10 is fully engaged with a container 20 for which the container protector 10 was designed, a seal is formed along the entire periphery of the container 20. This seal allows the interior lip 30 of the container protector 10 to act as an extension of the container 10, thereby effectively increasing the volume of the container 20. Accordingly, if the material positioned within the container 10 expands during cooking, baking, or during any other transitory condition put upon the material and/or container 20, the container protector 10 prevents the material from exiting the container 20.
The optimal dimensions of the height of the side skirt 32, and skirt 34, and interior lip 30 will depend on several factors, including but not limited to the specific application for the container protector 10 and the height of the container side and end walls 22, 24. However, it is contemplated that for most applications the height of the side skirt and end skirt 34 will be between 0.25 and 2.5 inches, and the height of the interior lip 30 will be between 0.1 and 2.5 inches. The thickness of the interior lip 30, side skirt 32, end skirt 34, and handle extension 34a will vary from one embodiment of the container protector 10 to the next, but for many applications a thickness between 0.1 and 0.7 inches will suffice. The length of the side skirts 32 and end skirts will vary depending on the size and configuration of the container 20 for which the container protector 10 is designed.
The various elements of the container protector 10 may be integrally formed as one unit, or the various elements may be separately formed and later affixed to one another. The container protector 10 may be formed of any material known to those of ordinary skill in the art that is suitable for the application for which the container protector 10 is used. Such materials include but are not limited to rubber, silicon, other polymers, or combinations thereof. It is contemplated that for some applications the container protector may be constructed of a silicone rubber material that is heat resistant up to 480 F, but the temperature that the material of construction will withstand in no way limits the scope of the container protector 10. The silicon rubber material is typically used in the construction of other types of bakeware due to its superior durability.
Other methods of using the container protector 10 and embodiments thereof will become apparent to those skilled in the art in light of the present disclosure. Accordingly, the methods and embodiments pictured and described herein are for illustrative purposes only.
It should be noted that the container protector 10 is not limited to the specific embodiments pictured and described herein, but is intended to apply to all similar apparatuses and methods for preventing a material positioned in a container from overflowing the container. Modifications and alterations from the described embodiments will occur to those skilled in the art without departure from the spirit and scope of the container protector 10.
