referring first to fig1 and 2 , a basic embodiment of the container system 100 is shown . the master container 102 operates to receive and contain solid food items ( not shown ), e . g . chips , vegetables , fruit , etc . the master container 102 a master aperture 118 formed by the sidewall 114 of the master container 102 . beneath the sidewall 114 is the master container bottom 116 . the master container sidewall 114 includes a ribbing 112 that extends about the periphery of the maser container sidewall 114 near the master container aperture 118 . the preferred ribbing 112 includes a single ridge arranged at the uppermost point of the master container sidewall 114 ; although , any protrusion or attachment structure fulfilling the objectives of the present invention will suffice . with further reference to fig3 , dimensioned to fit within the master container 102 is an interior container 104 . the interior container 104 includes an interior container sidewall 120 with diameter less than that of the master container sidewall diameter 114 . the interior container sidewall 120 supports a rim 110 that juts from the interior container sidewall 120 . the rim 110 extends from the sidewall 120 at least to the extent necessary to support the interior container upon the master container 102 , preferably upon the upper rib 112 . the rim 110 should be constructed of material , preferably a plastic , capable of supporting the weight of the interior container 104 and the material within the cavity ( not shown ) of the interior container . the interior cavity is covered by a seal 122 , preferably a sealed affixed by a removable adhesive . the seal may further include a tabbed outcropping 124 that permits a user to remove the seal 122 . when positioned upon the master container sidewall 114 , the interior container hangs thereon . it is further preferred that the interior container 104 include a sidewall 120 having at least a portion thereof includes a diameter that forms a minimum clearance fit with the master container sidewall 114 . such close fitting prevents lateral motion of the interior container 104 within the master container 102 . the interior container preferably includes a liquid food item , e . g . condiments , juice , soda , sauce , and the like . a liquid food item includes any food or beverage with fluid attributes , including loose granular spices , e . g . sugar or salt . a lid 106 is positionable about the ribbing 112 of the master container sidewall 114 , preferably in an interference fit . an interference fit when used in the present disclosure refers to a fit in which a first component fits within an entrance of a second component and the entrance of the second component includes a diameter smaller than that of the diameter of the first component and pressure from the first component deforms the second component to accept the first component in a sealed fashion . a minimum clearance fit is a fit in which a first component only just fits into the entrance of a second component without modification of the structure of either the first or second component . the interior of the lid 106 includes a substantially planar surface that matches the preferred upper substantially planar surface dimensions of the interior container . turning now to fig4 , the preferred cooperation between the lid 106 , master container 102 , and interior container 104 is illustrated . the interior container 104 includes a substantially planar upper surface that preferably forms a fit with the substantially planar lower surface of the lid 106 that prevents substantial longitudinal motion of the interior container . the cavity 126 preferably hangs in its entirety below the rim 110 of the interior container 104 . it is preferred that at least a minimum clearance fit is formed between the upper portions of the interior container 104 and the lower portions of the lid 106 . the lid 106 includes a lip 108 that hangs downwardly from the lid 106 . the lip forms an interference fit with the ribbing 112 of the master container sidewall 114 , and preferably includes dimensions that , in the absence of a minimum clearance fit , and sufficient to prevent substantial lateral motion of the interior container 104 . substantial lateral motion is motion sufficient to release portions of the rim 110 from portions of the master container sidewall 114 . it is preferred that any solid food 900 , positioned within the master container 102 include a height sufficient to have a proximity to the interior container that prevents substantial longitudinal motion of the solid food 900 within the master container 102 . in other words , the interior container 104 may act as a ceiling of the master container 102 . substantial longitudinal motion in relation to the solid food is motion capable of disfiguring at least 25 % of the food contents within the master container . substantial motion of solid food contents will vary by solid food , e . g . chips may toleration less longitudinal motion than apple slices . although the present invention has been described in considerable detail with reference to certain preferred versions thereof , other versions would be readily apparent to those of ordinary skill in the art . therefore , the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein .
a container is system is disclosed that includes multiple containers and a lid adapted to permit an interior container to hang from a master container . the interior container contains a fluid food substance and the master container includes a solid food substance .
