Description
[0001] The invention relates to a pot having a multipart setup, the
pot comprising an enveloping pot and a product pot, which is
received in the enveloping pot and serves for receiving a lotion or
the like, the enveloping pot and the product pot being made of the
same or different materials.
[0002] Pots of the type mentioned above are often realised as
material hybrids, which means that the pots made of a plurality of
components comprise components which consist of different
materials. In the case of the pots mentioned above, the pots are
mostly made of material hybrids or material mixes made of aluminium
and plastic, meaning an effective recycling presumes separating the
materials in particular in the case when the respective material
portion exceeds a certain range. Separating the materials often
proves time-consuming, in particular when separating the materials
cannot be carried out economically means sacrificing the inferior
or less valuable material to enable recycling the more valuable
material portion. This can occur, for example, when pots, which
have aluminium and plastic components, are molten for recycling
purposes so that the material is separated in this case by burning
or gasifying the plastic portion.
[0003] An extensive recycling of a pot made of several components
becomes possible using two different approaches, for example, the
pot of the first approach being designed such that the individual
components can be easily separated from each other, while the
second approach strives for a plastic portion as small as possible
to limit the non-recyclable portion of the pot to a minimum when
sacrificing plastic material.
[0004] The object of the present invention is therefore to propose
a pot which enables a simplified recycling of the used materials
and is distinguished by a particularly high portion of recyclable
materials.
[0005] To attain this object, the pot according to the invention
has the features of claim 1.
[0006] According to the invention, intersections are formed in the
pot between the different components for separation purposes, the
intersections being realised as detachable form-fit,
substance-to-substance or force-fit connections so that the pot
according to the invention does not have to be supplied to the
recycling process as a whole unit, but instead the components can
be separated before recycling takes place owing to the
intersections for the subsequent supply of the components to
different recycling methods or non-recyclable materials or
materials which can only be recycled with great effort can be
separated from the materials which are comparatively better suited
for recycling, if applicable.
[0007] A possible separation of the components is deemed
advantageous even if the material of only one component is to be
recycled, i.e., to be shapelessly returned to state of the original
material, whereas the other component is to be reused in its
current form. In this case, the components can be made of the same
material.
[0008] The pot according to the invention also makes it possible to
reduce a material portion, e.g., a plastic portion, to a range as
small possible, e.g., less than 10 percent, and to choose a uniform
recycling method for the other components, in particular in the
case when these materials consist of a uniform material, such as in
particular aluminium.
[0009] In any case, the pot according to the invention consequently
simplifies recycling the pot.
[0010] It is particularly advantageous if the pot comprises a pot
collar, which connects the product pot to the enveloping pot, and a
pot weight, which is disposed in a gap formed between the product
pot and the enveloping pot, a first connection being formed between
the product pot and the pot collar and a second connection being
formed between the pot collar and the enveloping pot, allowing the
option of producing an intricate pot made of different materials,
which can be separated at defined connective positions, if
required.
[0011] If the pot collar for forming the first connection is
connected to an abutment edge of the product via an upper collar
edge and supports itself on the pot weight, which is disposed in
the enveloping pot, by its lower support edge, the pot weight
itself can be used for connecting the components.
[0012] Preferably, the pot collar is connected to a connective
edge, which is formed on the enveloping pot, via a ledge, which
extends around the pot collar, for forming the second connection so
that the connection can be produced as easily as possible.
[0013] It is particularly advantageous if a transition surface
formed on the ledge is fully flush with an edge of the enveloping
pot formed on the connective edge so that an aesthetic and uniform
appearance is possible despite possibly present material
intersections.
[0014] If the product pot is designed as an exchangeable pot, which
is connected to the enveloping pot via a force-fit or form-fit
connection, the product pot can be separated from the enveloping
pot, if required, without requiring any particular effort.
[0015] It is particularly advantageous if the product pot comprises
an inner pot, an outer pot and a pot collar connecting the inner
pot to the outer pot, a first connection being provided between the
pot collar and the inner pot and a second connection being provided
between the pot collar and the outer pot.
[0016] Preferably, the product pot is received in an inner pot of
the enveloping pot, which comprises a pot jacket and a pot bottom
formed independently of the pot jacket, a first connection being
provided between an upper edge of the inner pot and an upper
opening edge of the pot jacket and a second connection being
provided between a lower edge of the pot jacket and the pot
bottom.
[0017] Designed in this manner, both the product pot and the
enveloping pot each have an aesthetically pleasing exterior
comprising an inner pot and an outer pot, the exterior remaining
intact even if the product pot and the enveloping pot are used
independently of each other.
[0018] If the pot connection is realised as a locking connection,
which comprises a shape-elastic locking element disposed in a gap
formed between the pot jacket and the inner pot of the enveloping
pot and penetrating recesses, which are disposed in the inner pot
of the enveloping pot and correspond to locking grooves in the
outer pot of the product pot, a particularly effective connection
between the product pot and the enveloping pot is made possible,
the connection not being visible in the outer appearance of the pot
and being easily detachable, if required.
[0019] Preferably, the locking element is designed as an annular
spring element, which comprises spring protrusions, which penetrate
recesses, which are disposed in a shared horizontal plane, in the
inner pot of the enveloping pot and locking grooves in the outer
pot of the product pot.
[0020] In another advantageous embodiment, the product pot is
received in an inner pot of the enveloping pot, the enveloping pot
comprising a pot collar formed independently of the inner pot and
an outer pot, a first connection being provided between the pot
collar and the inner pot and a second connection being provided
between the pot collar and the outer pot.
[0021] Preferably, a pot weight is disposed in such a manner in a
gap formed between the inner pot and outer pot that a lower edge of
the pot weight is disposed on a pot bottom of the outer pot and an
upper edge of the pot weight serves to both support an abutment
edge of the inner pot and to support an abutment edge of the pot
collar.
[0022] If an edge ridge, which is formed on the abutment edge of
the pot collar and is oriented toward the pot bottom, is disposed
in such a manner in an indentation realised on the abutment edge of
the inner pot and corresponding to the edge ridge that a fully
flush transition area from the edge ridge to the inner pot is
realised on an inner side of the enveloping pot facing the product
pot, a transition area unperceivable in the outer appearance of the
pot is made possible between the different components.
[0023] Preferably, an abutment edge of the product pot is disposed
on the abutment edge of the pot collar, the abutment edge of the
product pot preferably comprising an edge ridge, which is spaced
from the abutment edge of the pot collar, for forming a ring gap
radially open outward.
[0024] If the product pot is received in the inner pot of the
enveloping pot in a form-fit manner, a connection between the
product pot and the enveloping pot can be created by this which is
sufficient for the use of the pot.
[0025] Preferably, a force-fit radial material protrusion is formed
between a pot wall of the inner pot and a pot wall of the product
pot, meaning forming the clamping force becomes possible which
additionally secures the connection between the product pot and the
inner pot of the enveloping pot.
[0026] Advantageous embodiments of the invention are described in
further detail using the drawing.

[0037] FIG. 11 shows the pot illustrated in FIG. 10 with a product
pot removed from the enveloping pot;
[0038] FIG. 12 shows a cross-sectional view of the pot illustrated
in FIG. 10;
[0039] FIGS. 1 to 4 show a pot 20 which is realised in multiple
parts and in the case of the illustrated exemplary embodiment has
four components, namely a product pot 21, an enveloping pot 22, a
pot collar 23 connecting the product pot to the enveloping pot and
a pot weight 25 disposed in enveloping pot 22 in a gap 24 disposed
between product pot 21 and enveloping pot 22.
[0040] On an upper collar edge 26, pot collar 23 is connected to an
abutment edge 27 formed on the upper edge of product pot 21 and
supports itself on pot weight 25, which is disposed in enveloping
pot 22 and surrounds product pot 21 like a sleeve, by its lower
edge 28.
[0041] The connection between pot collar 23 and enveloping pot 22
is provided on a ledge 30 extending around pot collar 23, the
support of pot collar 23 on pot weight 25 by its support edge 28
achieving that a connective edge 29, which is formed on enveloping
pot 22, is fully flush with a transition surface 31, which is
formed by ledge 30.
[0042] As is derived from the explanations above, only two
connections 31, 32, namely connection 32 realised between product
pot 21 and pot collar 23 and connection 33 realised between pot
collar 23 and enveloping pot 22, need to be executed for producing
pot 20 as illustrated in FIGS. 1 to 4. Both connections 32 and 33
can be realised as either a press-fit connection, an adhesive
connection or a welded connection. Moreover, another connection can
be provided between enveloping pot 22 and pot weight 25, which can
also be realised as either a press-fit connection, an adhesive
connection or a welded connection.
[0043] As is discernible particularly from a synopsis of FIGS. 3
and 4, the relative arrangement of pot collar 23 in relation to
enveloping pot 22 enables an orientation of the pot collar by means
of pot collar 23 supporting itself on pot weight 25 disposed in
enveloping pot 22, in particular enabling the fully flush
arrangement between transition surface 31 and connective edge 29 of
enveloping pot 22 as described above and moreover a simple
adjustment of the contours of pot collar 23 to the contour of
enveloping pot 22, without requiring an exact adjustment of the
contour of support edge 28 of pot collar 23 to an abutment edge 35
of pot weight 25. Pot collar 23 and pot weight 25 can be connected
in particular via adhesion or welding.
[0044] Enveloping pot 22 can therefore be provided with complex
cross-sectional transitions in its contour, without requiring an
adjustment of the contour of pot collar 23 to the contour of
enveloping pot 22. In the case at hand, the contour of outer pot 22
is formed such that a circular cross section, which is formed on
connective edge 29 of the outer pot, continuously transitions into
a cross section which has changing radii and is formed on lower
edge 34 of outer pot 22 in the transition to pot bottom 36.
[0045] The embodiment which is intended for pot 20 and is
independent of the embodiment of product pot 21 and enveloping pot
22 moreover brings the advantage of a pot thread 37 formed on pot
collar 23 being able to be produced in a separate forming process
independently of product pot 21 and enveloping pot 22.
[0046] A pot 40 according to a second embodiment is illustrated in
FIGS. 5 to 9.
[0047] As discernible in particular in FIG. 6, pot 40 is set up
from a plurality of components, a synopsis of FIGS. 6 and 7 clearly
showing that a product pot 42, which is received in an enveloping
pot 41 and is designed as an exchangeable pot, is made up of an
inner pot 43, an outer pot 44 and a pot collar 45 connecting inner
pot 43 to outer pot 44.
[0048] In particular FIG. 8 shows that a first connection 46 for
connecting inner pot 43 to pot collar 45 is formed between an upper
opening edge 47 of inner pot 43 and a collar edge 48 of pot collar
45, and a second connection 49 is provided between an opening edge
50 of outer pot 44 and opening tabs 51 formed on the lower edge of
pot collar 45.
[0049] Enveloping pot 41 comprises an inner pot 53 received in an
outer pot 52, outer pot 52 being made up of a pot jacket 54 and a
pot bottom 55. In this case, a first connection 56 is realised
between an upper edge 57 of inner pot 53 and an opening edge 58 of
pot jacket 54 and a second connection 59 is realised between a
lower edge 60 of pot jacket 54 and connective tabs 61 disposed on
pot bottom 55. Analog to connections 46 and 49, connections 56 and
59 can be realised as a press-fit connection, an adhesive
connection or a welding connection.
[0050] Between product pot 42 and enveloping pot 41, a detachable
connective to device 62 is provided which is realised as a locking
connection and has a shape-elastic locking element which in the
instance at hand is made of an annular spring element 63, whose
shape is adjusted to the circumference of inner pot 53 of
enveloping pot 41 and which rests snuggly against a pot wall 71 of
inner pot 53 facing pot jacket 53 and is passed through a recess 65
in pot wall 71 with a total of four spring protrusions 64 in the
instance at hand. In this context, recesses 65 are disposed in
opposite sides of pot wall 71 in a horizontal connective plane
66.
[0051] As FIGS. 6 and 8 show, outer pot 44 of product pot 42
comprises locking grooves 68 in a connective plane 67 in an
arrangement corresponding to recesses 65. If product pot 42 is
inserted in enveloping pot 41, spring protrusions 64 of spring
element 63 are pushed radially outward upon contact with a pot
bottom 69 of product pot 42 and lock in locking grooves 68 when
reaching a congruent arrangement of connective planes 66, 67 so
that product pot 42 is detachably locked in enveloping pot 41. When
exerting a tensile force exerted on pot collar 45 against the
insertion movement, product pot 42 can be removed from enveloping
pot 41 by overcoming the spring force of spring element 63.
[0052] As in particular FIG. 9 shows, locking grooves 70
corresponding to locking grooves 68 are provided on the upper edge
of pot collar 45 so that a connective device corresponding to
connective device 62 can be provided between a screw cap (not
further illustrated) and pot collar 45 when the screw cap is
designed according to the corresponding embodiment.
[0053] In FIGS. 10 to 13, a pot 80 is illustrated in another
embodiment, pot 80 comprising a product pot 81 designed as an
exchangeable pot and being received in an inner pot 82 of an
enveloping pot 83. Enveloping pot 83 comprises a pot collar 84
formed independently to inner pot 82 and an outer pot 85, a first
connection 86 being realised between pot collar 84 and inner pot 82
and a second connection being realised between pot collar 84 and
outer pot 85.
[0054] Between inner pot 82 and outer pot 85, a gap 88 is formed in
which a pot weight 89 is disposed. Pot weight 89, whose lower edge
90 is disposed on a pot bottom 91 of outer pot 85, comprises an
upper edge 92, which serves on the one hand for supporting an
abutment edge 93 of inner pot 82 and on the other hand for
supporting an abutment edge 94 of pot collar 84.
[0055] On abutment edge 94, pot collar 84 is provided with an edge
ridge 95, which is oriented toward pot bottom 91 and is received in
an indentation 96 adjacent to abutment edge 93 of inner pot 82 and
corresponding to edge ridge 95. Owing to this, a fully flush
transition from edge ridge 95 to inner pot 82 is realised on an
inner side 97 of enveloping pot 83 facing toward product pot
81.
[0056] As in particular FIG. 12 shows, an abutment edge 98 of
product pot 81 is disposed on abutment edge 94 of pot collar 84,
which belongs to enveloping pot 83, abutment edge 98 comprising an
edge ledge 100, which is distanced from abutment edge 94 of the
enveloping pot, for forming a ring gap 99 open radially
outward.
[0057] As in particular a synopsis of FIGS. 10 and 11 clearly
shows, product pot 81 is removably received in enveloping pot 83,
ring gap 99 illustrated in FIG. 12 making it possible to grab edge
ledge 100 formed on product pot 81 and to pull out product pot 81
from inner pot 82 of enveloping pot 83. As particularly shown in
the exploded view of FIG. 13, a radial material protrusion 101 is
formed on inner pot 82 of enveloping pot 83 for this purpose,
material protrusion 101 enabling forming a radial clamping force
between inner pot 82 of enveloping pot 83 and product pot 81, the
clamping force requiring a defined tensile force for removing
product pot 81, which is received in enveloping pot 83 in a
form-fit manner, from enveloping pot 83 to prevent product pot 81
from sliding out unintentionally from enveloping pot 83.
[0058] Both connections 86, 87 mentioned above between pot collar
84 and inner pot 82 and outer pot 85 of enveloping pot 83 and a
radial connection between pot weight 89 and pot collar 84 can be
realised as a purely force-fit connection or alternatively or
additionally as an adhesive or welded connection according to a
corresponding interpretation, the pot weight being provided with a
gap 102 illustrated in particular in FIG. 13 for the force-fit
connection between pot weight 89 and pot collar 84 of the pot
weight, gap 102 enabling an embodiment of sleeve-shaped pot weight
89 in the manner of a spring sleeve so that a pre-tension force is
formed between pot collar 84 and pot weight 89 on the circumference
of pot weight 89.
