The drawing figures are not necessarily drawn to scale and certain figures may be shown in exaggerated, generalized, or schematic form in the interest of clarity and conciseness.
Referring initially to FIG. 1, a cover according to an exemplary embodiment is disclosed generally as 100. Cover 100 includes a first cover piece 102 that may be separably and/or hingably coupled with a second cover piece 104. First cover piece 102 and second cover piece 104 may be substantially similar but for one or more hooks 130 located on the first cover piece 102 that are insertable into respective slots 140 located in the second cover piece 104, as will be described further below.
Cover 100 may be configured for use with a container C, e.g., a chafing dish, food pan, serving tray, or storage container, to name a few. In embodiments, first cover piece 102 and/or second cover piece 104 may be formed of a transparent material, e.g., a polymeric material such as plastic, a composite or glass, to allow a user to view the contents of the container C without lifting the cover 100. First cover piece 102 and/or second cover piece 104 may have a refractive index, e.g., between and including about 1 and about 2. In embodiments, first cover piece 102 and second cover piece 104 may have other respective refractive indices. In embodiments, first cover piece 102 and/or second cover piece 104 may be wholly transparent or partially transparent, e.g. first cover piece 102 and/or second cover piece 104 may have a transparent region and/or may incorporate a transparent window.
Referring to FIGS. 2, and 3, the first cover piece 102 is shown in perspective view. First cover piece 102 may have a substantially rectangular plan profile. In embodiments, first cover piece 102 may have a differently-shaped plan profile, e.g., square, circular, ovoid, elliptical, or triangular to name a few. First cover piece 102 may have a complementary configuration to a container upon which it sits. As shown, first cover piece 102 may have a generally concave cross-sectional profile, e.g., first cover piece 102 has generally downwardly-sloping surfaces extending away from a geometric center of the first cover piece 102. First cover piece 102 may be configured to be placed on or fit over, for example, container C. First cover piece 102 includes a body 106 at least partially surrounded by a rim 108. Body 106 may be configured as a substantially planar section of first cover piece 102. Rim 108 my have a substantially flange configuration that extends away from the body 106. One or more sloped walls 107 may be disposed between the body 106 and the rim 108 such that the body 106 is disposed above the rim 108. When first cover piece 102 is placed atop container C, an interior volume is formed within which substances, such as solid and/or liquid food may be stored.
Cover piece 102 may include one or more tabs 110 extending laterally away from the rim 108. Tabs 110 present a protruding surface for engagement by, e.g., the index finger and thumb of a user to lift an end of cover piece 102. Tabs 110 may be located on respective corners of the rim 108 of cover piece 102 or elsewhere along the periphery of the rim 108. In embodiments, such tabs may be any suitable shape or configuration, e.g., a knob, handle, or ledge, to name a few.
