Field of Invention
The present invention relates to a container and an assembly of containers, andmore
particularly relates to the container and the assembly of containers wherein one
container is placed over the other while providing stability in such an assembly.
Background
Conventional containers are known for storing different kind of substances for
household and commercial purposes. These containers are transported from one place
to another for their utilization using various transportation means. For optimum use of
storage space in a room as well as space of the transportation means, the containers
are placed one over the other. However, these containers are not very stable in such
assembly, resulting in movement of the containers from their position. Such
movement also leads to damage to the containers, spillage and other adverse impacts
on containers. In case of large containers, heavy containers or a large number of
containers placed one on top of the other; the risk of such damage is even higher due
to the high pressure on the containers towards the bottom of the assembly.
US publication number US2007/0114200 tries to resolve this problem and discloses a
bottle with a lower surface having a conical convex recess for receiving the conical
ceiling of the upper surface of the next adjacent bottle while the bottles are placed
over the other. However, the bottle in said application does not provide a
structurethatcould efficiently be used in other kind of containers, especially when
there is high pressure on the containers towards the bottom of the assembly.The
conical shape of ceiling and conical recess make the solution offered by this patent
inefficient for use in situations where there is high pressure on the containers towards
the bottom of the assembly. Further, the protrusions and recess provided by the said
patent make the solution offered by this patent inefficient for use in situations where
there ishigh pressure on the containers towards the bottom of the assembly.
The problem to be solved is to provide a container and an assembly of containers
where the containers at the bottom can handle high pressure imposed by other
containers above them, especially by large containers, heavy containers or a large
3
number of containers placed above them and the problem is solved by providing a
container and an assembly of containers wherein containers have a combination of
depressions and protrusions and the top and bottom surface area of the containers is
used for interlocking the containers one over the other and providing rotation barrier.

Detailed disclosure of the Invention
The present invention discloses a container (100) and an assembly of containers (50)
capable of being interlocked one over the other. The container (100) is provided with
chamber used to store the substances like oil, edible oil, water, other liquids and fluids
etc. The chamber is covered from the top by a top surface (120) and from the bottom
by a bottom surface (140), such that the chamber of the containers (100) is enclosed
between the top surface (120) and the bottom surface (140).
As shown in Fig. 1, the assembly (50) includes a plurality of containers (100), which
are placed and interlocked over the other such that the top surface (120) of one
container (100) receives the bottom surface (140) of the other container (100). The
assembly can include a vertical interlocking of two, three, four or even more than four
containers (100).
As shown in Fig. 2, the top surface (120) of the container (100) includes an opening
covered by a closure (126), such as a cap or any other closing means. The opening of
11
the top surface (120) of the container (100) is preferred to extend to more than half
surfacearea of the top surface (120) as the closure (126) covering the opening would
provide a larger surface area for stable resting of the container (100), which is placed
over the lower container. In one of the embodiments, approximately two third of the
dimension of the top surface (120) of the container (100) is covered by the opening,
thereby providing a larger surface area for keeping the assembly stable. The container
(100) also includes four longitudinal walls (150), which is provided with ribs (152).
These ribs (152) are uniformly, horizontally provided on the surface of the
longitudinal walls (150) to provide strength to the longitudinal walls (150) of the
container (100) and to avoid its deformation.
As shown in Fig. 3, the top surface (120) of the container (100) includes four
depressions (122) provided at the corners or the edges of the top surface (120). These
depressions (122) are wide and planar to enable proper resting of the bottom surface
(140) of the container (100). These four depressions (122) are separated by four top
surface portions (124) of the top surface (120) such that between any two depressions
(122) is one top surface portion (124). Therefore, the top surface (120) includes an
opening covered by the closure (126), depressions (122) at the four corners of the top
surface (120) surrounding the opening on the top surface (120) and the top surface
portions (124) between the depressions (122). The top surface portions (124)
comprise of a pair of large top surface portions (132) and a pair of small top surface
portions (134). The top surface portions (124) are so placed on the top surface that the
depressions (122) extend more towards the side and because of the small top surface
portions (134), a larger surface area of the depressions (122) is available to receive the
bottom surface of the container (100). These large top surface portions (132) and
small top surface portions (134) are provided on the opposite sides of the top surface
(120) such that the two large top surface portions (132) face each other and the two
small top surface portions (134) face each other. The pair of large top surface portions
(132) is provided with a second cavity (130). These four depressions (122) are also
provided with four notches (128) each, which extend towards the longitudinal wall
(150) of the container (100), thereby further increasing the strength of the top surface
(120) and the longitudinal wall (150) of the container (100) so that the top surface
(120) can withstand the load of the other containers above it.
12
As shown in Fig. 4, the bottom surface (140) of the container (100) includes four
protrusions (142) and four bottom surface portions (141) such that these four bottom
surface portions (141) separate four protrusions (142) on the bottom surface (140).
The center of the bottom surface (140) includes a first recess (144), which is
structured to receive the closure (126) of the top surface (120) during interlocking.
The first recess is surrounded by the four protrusions (142) from four corners or edges
of the bottom surface (140) and the bottom surface portions (141). The bottom surface
portions (141) of the bottom surface include a pair of large bottom surface portions
(148) and a pair of small bottom surface portions (149). The bottom surface portions
(141) on the bottom surface (120), the protrusions (142) are so placed on the bottom
surface (140) that the protrusions (142) extend more towards the longitudinal wall
(150) and because of the small bottom surface portions (149), a larger surface area of
the protrusions (122) is available to be received by the depressions (122) of the top
surface (120) of the container (100). These four protrusions (142) are also provided
with four notches (128) each to increase the strength of the edges of the bottom
surface (140) of the container (100) so that the bottom surface (140) can withstand the
load of the other containers (100) above it. These large bottom surface portions (148)
and small bottom surface portions (149) are provided on the opposite sides of the
bottom surface (140) such that the two large bottom surface portions (148) face each
other and the two small bottom surface portions (149) face each other.The bottom
surface (140) also includes a channel (146). The channel (146) extends axially
outward from the first recess (146) for venting the air trapped between the closure
(126) and the first recess (144) during interlocking. The channel (146) is a narrow
path on the larger bottom surface portion(s) (148), thereby providing a passage for air.
As shown in Fig. 5(a) and 5(b), when the containers (100) are assembled over the
other, the depressions (122) of the top surface receive the protrusions (142) of the
bottom surface in a way that the four protrusions (142) of the bottom surface (140)
rest on its corresponding four depressions (122) of the top surface. And at the same
time, the first recess (144) of the bottom surface (140) receives the closure (126), such
that the closure (126) rests on the first recess (144). When the first recess (144)
receives the closure (126), the air gets entrapped between them. This entrapped air is
vented into the surrounding environment or removed by the channel (146). Moreover,
at the same time, the bottom surface portions (141) i.e. the large bottom surface
13
portions (148) and the small bottom surface portions (149) also receives the top
surface portions (124) i.e. large top surface portions (132) and the small top surface
portions (134) respectively, thereby vertically interlocking the bottom surface (140) of
the container (100) with top surface (120) of the another container placed above it.
The four bottom surface portions (141) when receives the four top surface portions
(124) interlocks the top surface (120) with the bottom surface (140) by forming a
rotational barrier (136) between the top surface (120) of the container (100) with the
bottom surface (140) of the another container (100).
As shown in Fig. 6, during the interlocking of the containers (100) i.e. when the four
depressions (122) receive the four protrusions (142) and the first recess (144) receives
the closure (126), the pair of large bottom surface portions (148) also receives the pair
of large top surface portions (132), thereby forming the rotational barrier (136). As
shown in Fig. 2, the large top surface portions (132) includes a second cavity (130),
such that the second cavity faces the large bottom surface portions (148) and both
large bottom surface portions (148) along with the second cavity (130) forms a space
between the large bottom surface portions (148) and the second cavity (130) during
interlocking. This space allows the user to efficiently hold or lift the containers (100)
from its bottom surface (140), especially when the containers (100) are required to be
unassembled or when their interlocking is required to be removed by providing ample
gripping to the user on the bottom surface (140).
As shown in Fig. 7(a) and 7(b), the longitudinal wall (150) of the container (100) is
also provided with reinforced ribs (154). These reinforced ribs are structured to
include two convex portions (156), which are elevated from the first cavity (155). The
first cavity (155) together with the two convex portions (156) forms the reinforced
ribs on the longitudinal walls (150). The two convex portions may be connected with
each other from their one side by converging towards each other towards their one
side. These reinforced ribs (154) are provided at the junction between the longitudinal
walls (150) i.e. they are provided at the meeting point of the two longitudinal walls,
thereby strengthening the edges or corners of the container (100) and enabling the
container (100) to withstand the load of the above containers (100). These reinforcing
ribs (154) are also provided horizontally between the top surface (120) and bottom
surface (140) These reinforcing ribs (154) are provided in the vicinity of the top
14
surface (120) and bottom surface (140) i.e. near the top surface (120) and bottom
surface (140) and on the longitudinal wall (150), thereby strengthening the corners or
edges connecting the longitudinal walls (150) with the top surface (120) and bottom
surface (140) to withstand the load or pressure of the above containers (100) and
avoiding them from being deformed.
As shown in Fig. 8(a) and 8(c), the longitudinal walls (150) of the container (100)
includesgrooves (159). The grooves (159) are structured vertically on the longitudinal
walls (150) and near the bottom surface (140) of the container (100).These groove(159) extend radially inwards to said bottom surface (140), thereby strengthenings
the edges adjoining said bottom surface (140) and said longitudinal walls (150) of the
container.
