DETAILED DESCRIPTION OF EMBODIMENTS
[0008] Stackable containers featuring a generally oval shape and
constructed in accordance with the present invention are indicated
in general at 10, 12 and 14 in FIGS. 1, 2 and 3, respectively. More
specifically, a small dish container is indicated in general at 10
in FIG. 1, a tub container is indicated in general at 12 in FIG. 2
and a large dish container is indicated in general at 14 in FIG. 3.
While the invention is described below in terms of these three
container sizes and shapes, it will be understood that containers
incorporating the invention and featuring alternative sizes and
shapes may be constructed.
[0009] Containers 10, 12 and 14 are preferably constructed from a
plastic, such as polypropylene, so as to be lightweight yet strong
and durable. Furthermore, the containers are preferably constructed
by molding the components described below. In addition, the
containers are preferably transparent or clear so that the contents
may be viewed without opening the containers. While the containers
are particularly well-suited for storing food products, they could
alternatively be used to store other items.
[0010] As illustrated in FIG. 1, small dish container 10 features a
body 16 having an open top and a lid 18. FIGS. 2 and 3 illustrate
that tub container 12 similarly features a body 20 having an open
top and lid 22 while large dish container 14 includes body 24
having an open top and lid 26. As illustrated in FIGS. 4-6, the
lids 18, 22 and 26 cover and are removable from the open tops of
bodies 16, 20 and 24. More specifically, with reference to the
small dish container and FIG. 4, the body 16 of the small dish
container features a circumferential rim portion 30 that surrounds
its open top and generally lies in a horizontal plane. The outer
edge of the rim features a slight downturn, illustrated at 32 in
FIGS. 4-6. The lid 18 of the small dish container features a
downward-extending circumferential rim 34 that terminates at in a
circumferential lip 36. The lid rim 34 and lip 36 are sized so that
the lip engages the downturned outer edge of the body rim when the
lid 18 is placed on the body 16, as illustrated in FIG. 1. As a
result, the lid 18 is secured to the body 16, preferably in a
sealing fashion.
[0011] Container bodies 20 and 24 and lids 22, 26 and 28 feature
the same rim construction as the small dish container 10 and may be
closed, and preferably sealed, in the same fashion.
[0012] The body 16 of small dish container 10 also features a base
42 formed by a downward-protruding annular wall. The body 20 of tub
container 12 similarly features base 44 while the body 24 of large
dish container 14 similarly features base 46. Bases 42 and 44 are
preferably the same size to permit interchangeable stacking, as
described below. As is clear from the figures, base 46 is wider and
deeper so as to require a larger supporting surface (as compared to
bases 42 and 44).
[0013] The top surfaces of the lid 16 of small dish container 10
and lid 22 of tub container 12 each features a recess 52 and 54,
respectively. Recesses 52 and 54 are preferably the same size and
are sized to receive the bases 42 and 44 of the bodies of the small
dish and tub containers. As a result, the small dish and tub
containers may be stacked on top of each other, as illustrated in
FIGS. 4-6. While FIGS. 4-6 show the small dish container stacked on
top of the tub container, the tub container may alternatively
stacked on top of the small dish container.
[0014] The lid 26 of the large dish container 14 has a top surface
that features an annular ridge 62 with an inner edge that defines
center recess 64 (FIGS. 3 and 4). Lid 28 of FIGS. 4-6 similarly
features annular ridge 66 which defines center recess 68 (FIG. 4).
Annular ridges 62 and 64 also feature outer edges. This allows lids
26 and 28 to support the small dish, tub or large dish
containers.
[0015] More specifically, as illustrated in FIGS. 4-6, center
recess 64 of lid 26 (and center recess 68 of lid 28) is sized to
receive bases 42 or 44 of the small dish and tub containers (10 and
12, respectively, of FIGS. 1 and 2). In addition, the outer edges
of the annular ridges 62 and 66 of lids 26 and 28 are sized to fit
within the base 46 of large dish container 24. As a result, the
large dish containers (14 in FIG. 3) may be stacked on top of one
another and/or the small dish and tub containers may be stacked on
top of the large dish containers or each other. This provides the
stackable containers of the present invention with flexibility in
terms of stacking configurations.
[0016] The large dish containers, however, may not be stacked on
top of either the small dish container or the tub container. This
is because the recesses 52 and 54 of the small dish and tub
containers are too small to receive the base 46 of the large dish
container. Stacking the large dish container on top of either the
small dish or tub containers could create a top heavy or otherwise
unstable condition which would be undesirable as the stacked
containers could easily topple. As a result, the present invention
minimizes the chances of this condition occurring.
[0017] The present invention therefore provides containers that are
easy to stack for storage, display or carrying. The present
invention also minimizes the chances that the containers will be
stacked in a top heavy or otherwise unstable fashion.
[0018] While embodiments of the invention have been shown and
described, it will be apparent to those skilled in the art that
changes and modifications may be made therein without departing
from the spirit of the invention.
