the following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings . the embodiments are described in such detail as to clearly communicate to one of ordinary skill how to make and use the claimed invention . however , the amount of detail offered is not intended to limit the anticipated variations of embodiments ; on the contrary , the intention is to cover all modifications , equivalents , and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims . a foodservice container caddy ( hereinafter referred to as a “ caddy ”) according to various embodiments can be used to transport and place foodservice containers without portions of the foodservice containers coming into contact with a surface . in addition , such a device can enable foodservice staff to handle foodservice containers without risk of personal exposure to hazardous surfaces . note that although caddies designed for bus tubs and steam table pans are used as the primary examples throughout , some embodiments of a caddy can be used for handling various different foodservice containers . as used herein , the terms “ container ” or “ foodservice container ” are used interchangeably unless otherwise specified . foodservice containers include , but are not limited to , tubs , trays , pans , or the like used in the foodservice industry or foodservice establishments such as restaurants , dining halls , cafeterias and cafés . bus tubs , steam table pans , and food serving trays are examples of foodservice containers . in some embodiments , the container can have a shape that includes an upper portion and a lower portion . for example , a container might have a bottom , one or more sides , and a lip structure , where the bottom and a lower portion of the sides make up the lower portion of the container , and the lip structure and an upper portion of the sides make up the upper portion of the container . in some embodiments , the lip structure of the container can be a circumferential “ lip ” that extends along the top of all sides of the container , handle structures integrated into the structure of the container , or the like . in some embodiments , a caddy allows foodservice staff to handle and utilize a container without portions of the container coming into contact with a surface . for example , a bus tub , which can be utilized by foodservice staff to clean a dining - room table and collect used diningware after consumers have departed , may accumulate water , grease , or some other liquids on its outer surfaces after the bus tub has been deposited on a kitchen surface to unload the used diningware to be cleaned . placing the bus tub into a caddy can help ensure that , when the bus tub is carried to and placed on a surface or dining - room surface , any liquids on the outer surface of the container do not touch or otherwise contaminate the dining - room surface , thereby preventing such liquids from damaging the dining - room surface or damaging clothing or other personal assets of customers . as used herein , the term “ dining - room surface ” includes , but is not limited to , a dining - room table , dining - room floor , dining - room upholstery , or the like . in another example , a steam table pan , which can be utilized by foodservice staff to deliver cooked food to a steam table in a dining room , may , in addition to accumulating water on its outer surface from steam condensation , have surfaces that are too hot to be safely handled by foodservice staff without some form of thermal protection device , such as a thermal glove . some embodiments of the caddy can incorporate materials that have insulating properties to ensure that , when the steam table pan is carried to or from a steam table , any liquids that have accumulated on the outer surfaces of the steam table pan do not drip onto dining room surfaces , and that foodservice staff , dining - room surfaces , and the like are not damaged , injured , or otherwise harmed by the temperature of the steam table pan . in some embodiments , the caddy can include a sleeve ( also referred to herein as a “ receptacle ”, “ sheath ”, and the like ) and handles . in some embodiments , the sleeve can be made of multiple layers of materials , some of which are different from other layers . for example , in some embodiments , the sleeve can include an outer layer that comes into contact with dining - room surfaces . the sleeve can also include an inner layer that comes into contact with a container placed in the caddy . in some embodiments , the inner layer can have insulating properties . various layers of the sleeve can be made of materials such as fabric , vinyl , leather , plastic , metal , wood , or the like . one or more of the sleeve layers may be waterproof , water - resistant , grease - proof , grease - resistant , proofed or resistant against absorbing or retaining other liquids . in some embodiments , the handles can be irreversibly attached to the sleeve . for example , where the sleeve is formed or constructed from a single piece of material , the handles can be formed or constructed out of the same piece of material . in some other embodiments , the handles can be reversibly or irreversibly attached to the sleeve via one or more various attachment means including , but not limited to , snap - buttons , zippers , adhesives , stitching , stapling , or the like . in some embodiments , the handles can be holding straps , lengths of cord or rope , other pieces of material , or the like . in some embodiments , the handles can be coupled to each other to form a handle assembly which may be formed or constructed from a single piece of material including , but not limited to , fabric , vinyl , leather , plastic , metal , wood , or the like . in some embodiments , some or all of the handle assembly or handles can extend on one or more sides of some or all portions that make up the sleeve . a handle assembly can extend along the outer layers of the sleeve , or between two or more layers of some or all portions that make up the sleeve . in some embodiments , part of the handle assembly extends along the inner layers of the side portions of the sleeve , while part of the handle assembly extends between the inner layer and outer layer of the bottom portion . the portion of the handle assembly which extends between two or more layers of a portion of the sleeve can be attached to one or more of the layers . in some embodiments , a part of the handle assembly that extends between the inner layer and outer layer of the bottom portion of a sleeve can be attached to the inner layer via stitching . in other embodiments , parts of the handle assembly are attached to both inner and outer layers via one or more forms of attachment including , but not limited to , stitching , stapling , adhesives , soldering , welding , or the like . in some embodiments , the various portions of the caddy can be attached to each other using various forms of attachment . for example , in some embodiments where the caddy includes two side portions and one bottom portion , the side portions can be attached to each other via stitching that extends through some or all layers of material that make of the side portions , and the side portions may be attached to the bottom portion via an adhesive . in some other embodiments , other forms of attachment or combinations thereof may be utilized , including , but not limited to , stapling , soldering , welding , or the like . in some embodiments , an additional piece of material covers the edge along which an attachment between two or more portions of the sleeve extends . for example , an attachment cover can extend along the edge between the side portions and the bottom portion , with stitching extending between one or more points on the attachment cover and through some or all of the layers that make up the side portions , bottom portion , or both . the attachment cover may be coupled to the portions by a different form of attachment . in some embodiments , the side portions are attached to the bottom portion via stitching , while the attachment cover can be attached to both portions via one or more of adhesives , stapling , another set of stitching , soldering , welding , or the like . in some embodiments , the sleeve of the caddy can be sized to fit over the lower portion of a foodservice container in such a manner that the fit is snug , yet still enables the foodservice container to be removed from the caddy with minimal effort . for example , in some embodiments the sleeve of the caddy may be sized to fit snugly and removably over the lower portion of a bus tub , where the sleeve must ensure that the outer surfaces of the bus tub do not contaminate or otherwise damage or room surfaces , foodservice staff , consumers , or the like , yet also enable the bus tub to be quickly removed from the sleeve to unload dirty dishes or the like . in some other embodiments , the sleeve of the caddy can be sized to fit loosely over the lower portion of a foodservice container such that the foodservice container can be removed from the caddy as quickly as possible . for example , in some embodiments the sleeve of the caddy may be sized to fit loosely over the lower portion of a serving tray , where the serving tray must be removed from the sleeve often . in other embodiments , the sleeve of the caddy can be sized to fit tightly over the lower portion of a foodservice container such that the caddy forms a tight seal around the lower portion of the foodservice container . for example , an insulated sleeve of the caddy can be sized to fit tightly over the lower portion of a serving tray , where quick removal of the foodservice container from the caddy is a lower priority . referring first to fig1 , embodiments of a foodservice container caddy (“ caddy ”) 102 are illustrated and discussed . fig1 illustrates a perspective view 100 of caddy 102 , which is adapted to receive part of container 103 , which has a lower
