Description
[0001] The invention relates to a lid for a container, and
additionally to a container with lid, where the container displays
a container wall, a container bottom and a container opening with
an opening rim, and the lid is located on the radially inner side
of the opening rim, into which it can be snapped or clamped.
[0002] A container with lid of this kind can, for example, be a
paint pot, where the container opening displays an opening rim
projecting radially inwards from the container wall, in which the
lid is fixed by clamping or snap-fitting. Also open to
consideration are containers for other materials, especially liquid
materials, that display an opening rim on the radially inner side
of which the lid rests.
[0003] The opening rim can, as on the aforementioned paint pot, for
example, project inwards from the container wall and serve to
prevent the material held in the container, e.g. paint, varnish and
the like, from easily escaping through the container opening in the
event of movement of the container. Furthermore, an inwardly
projecting rim makes it possible to wipe off liquid material held
in the container, such as paint, varnish and the like, from a tool,
e.g. a brush.
[0004] The lid and the container can have any desired
cross-sectional shape, particularly a circular, oval, square or any
desired rectangular cross-section.
[0005] As a rule, containers of this kind are opened in that a tool
is applied, over the opening rim of the container and under an
annular rim flange of the lid, the latter being detached from the
opening rim of the container by levering open with the help of the
tool. If the container is re-sealed with the lid, it cannot be
seen, possibly apart from slight marks made by the levering tool,
whether or not the lid has already been removed previously.
[0006] The object of the invention is to provide a lid, and a
container with lid, with an indicator that clearly shows whether or
not the lid has previously been lifted or detached from the
container.
[0007] According to the invention, the object is solved in that the
radially outer edge area of the lid displays an opening area,
through which a tool serving as a lever can extend through the lid
edge, and a rim of the lid is provided below the opening area,
under which the free end of the levering tool can act on the lid
and the lid can be at least partially lifted off the container by
pivoting the tool against the rim of the lid, and the edge of the
opening area displays at least one part that can be torn off the
lid, or broken, when the tool is inserted into the opening area or
the lid is levered open.
[0008] As a result of the part on the rim of the opening area that
can be torn off when the tool is used, it can unequivocally be seen
whether or not the lid has already been detached from the container
rim on a previous occasion. The opening area of the lid with the
tear-off part thus serves as a tamper-proof seal for a container
sealed with a lid.
[0009] In a preferred embodiment of the invention, the opening area
is designed as a through-hole in the edge area of the lid, through
which a suitable tool for levering open the lid can extend. The
through-hole can display a rim, facing towards the radially outer
side of the lid, that is designed as a narrow web and can thus be
torn when levering off the lid.
[0010] In particular, the through-hole can be designed in the form
of a slot extending in the circumferential direction of the
lid.
[0011] In another development of the invention, the opening area
can be sealed off by a cover before insertion of a tool, said cover
being connected to the edge of the opening area via ties, and
arranged and designed in such a way that a levering tool open to
consideration cannot be inserted into the opening area, and up to
the inner rim of the lid for application of the levering tool,
without breaking the ties.
[0012] The opening area originally at least partly sealed off by
the cover can display a rim section facing towards the radially
outer side of the lid. The rim section can likewise be designed,
e.g. as a narrow web, in such a way that it can be torn when the
lid is levered off by the tool.
[0013] In a preferred embodiment of the invention, the radially
outer edge area of the lid is designed in the form of an
essentially radially extending flange, adjacent to which in the
radially inward direction is an area with an essentially V-shaped
cross-section, specifically with an essentially axially extending
annular part with an indentation on the outer side, the radially
outer edge of which forms the rim of the lid for application of the
levering tool.
[0014] The indentation can particularly have the form of a radially
inward-facing right-angle bend.
[0015] Furthermore, the end of the indentation facing away from the
radially extending flange of the lid can display a radially
outward-facing annular projection, the outer side of which
transitions into an inwardly inclined surface.
[0016] The indentation on the outer side of the axially extending,
annular part of the lid serves to engage an inward-facing
projection in the area of the container opening on the inside of
the container to be sealed with the lid. The lid can thus be
fastened on the opening rim of the container opening by means of a
snap-fitting connection. On the other hand, the essentially axially
extending, annular part of the lid can also be clamped into the
radially inward-lying rim of the container opening. In this case,
the annular part of the lid interacting with the container opening
is expediently of slightly conical design.
[0017] The inwardly inclined surface adjacent to the radially
outward-facing, annular projection, or immediately adjacent to the
inward-facing right-angle bend, serves as a guide and centring aid
when fitting the lid on the inner rim.
[0018] An axial annular flange can be integrally moulded on the end
of the inclined surface pointing axially away from the edge area of
the lid.
[0019] Starting from the axial annular flange, the inclined surface
or the radially inward-facing right-angle bend of the essentially
axially extending annular part of the lid, an annular, conical area
is provided that extends radially inwards, axially to the edge area
of the lid and essentially up to the level of the edge area of the
lid, such that, starting from its edge area, the cross-section of
the lid is of essentially V-shaped design. This V-shaped area
transitions, via an essentially trapezoidal section, into an
axially inwardly offset, middle area of the lid.
[0020] The outer edge of the radially extending flange of the lid
can be of inclined design in the direction of the radially
extending part of the V-shaped area. As described in more detail
below, the purpose of the inclined outer edge of the lid is to
ensure that a tool open to consideration for levering open the lid
cannot reach between the rim area of the container opening, on
which the radially extending flange of the lid lies, or from which
it is separated by a very small gap, and the outer edge of the
radially extending flange of the lid. The inclined design of the
edge additionally prevents the tool from acting on the
outward-lying upper edge of the edge area in order to lever open
the edge area of the lid and enter the area between the outer edge
of the lid and the rim area of the container opening.
[0021] The aforementioned object is also solved by a container with
a lid having the design features described above, where the
container displays a container wall, a container bottom and a
container opening with an opening rim, in which context the lid is
located on the radially inner side of the opening rim and can be
snapped or clamped into the container on the inside of the
container. In a preferred embodiment of the container, the
container opening displays an inwardly extending rim, against which
the radially outer edge of the lid rests.
[0022] In an expedient development of the container, the rim of the
container opening extending radially inwards transitions, on the
inside, into a flange part that is inclined relative to the
container bottom and displays a gap from the rim of the lid for
application of the levering tool, such that the free end of the
levering tool can be inserted between the flange part and the
application rim and act below the application rim.
[0023] The end of the inclined flange part pointing towards the
container bottom can be provided with a radially inward-facing,
circumferential projection that snaps into an indentation in the
essentially axially extending part of the V-shaped area of the lid
and leaves the rim for application of the levering tool clear.
[0024] The projection is preferably designed with a T-shaped
cross-section.
[0025] A practical example of the invention is described in detail
below, based on the drawing. The Figures show the following:
[0026] FIG. 1A longitudinal section through a practical example,
comprising a container and a lid,
[0027] FIG. 2 An enlarged view of rim area A in FIG. 1,
[0028] FIG. 3 A top view of the lid of the container shown in FIGS.
1 and 2,
[0029] FIG. 4 An enlarged view of rim area B in FIG. 3,
[0030] FIG. 5 A section along line C-C in FIG. 4,
[0031] FIG. 6 A longitudinal section through the lid shown FIG. 3,
and
[0032] FIG. 7 An enlarged view of rim area D in FIG. 6.
[0033] FIGS. 1 and 2 of the drawing show a container 1 with lid 2,
where container 1 displays a container wall 3, a container bottom 4
and a container opening 5 with an opening rim 6. Lid 2 is located
on the radially inner side of opening rim 6 and can be snapped or
clamped into opening rim 6.
[0034] Container 1 with lid 2 is a paint pot, where container 1 and
lid 2 are manufactured by injection moulding.
[0035] Container opening 5 displays an opening rim 6 that extends
radially inwards and on whose radially inner side the radially
outer edge 7 of lid 2 rests.
[0036] As can be seen in FIGS. 3 to 5, radially outer edge area 8
of lid 2 displays an opening area 9. The purpose of this opening
area 9 is that a levering tool can be inserted through it to open
the lid.
[0037] As shown in FIG. 5, in particular, lid 2 displays a rim 10
below its edge area 8, i.e. at an axial distance from edge area 8,
under which the free end of the levering tool can act on the lid,
and lid 2 can be at least partly lifted off container 1 by pivoting
the tool against rim 10. The edge of opening area 9 displays at
least one part 11 that can be torn when the lid is levered open by
the levering tool.
[0038] The condition of part 11 indicates whether lid 2 has not
previously been detached from container 1, in which case part 11 is
undamaged, or whether lid 2 has already been detached from
container 1, in which case part 11 has been torn during levering up
of lid 2 by the tool, in which context the tool is supported on
opening rim 6 of container 1.
[0039] As indicated in FIG. 3, opening area 9 is designed in the
form of a slot extending in the circumferential direction of lid 2,
where part 11 of the edge of the slot has the form of a narrow web
extending on the outer side of opening area 9. If lid 2 is lifted
by the levering tool, in which context said tool is supported on
part 11 and opening rim 6 of container 1, this causes part 11 to
tear.
[0040] As furthermore shown in FIGS. 5 to 7, radially outer edge
area 8 of lid 2 is designed in the form of an essentially radially
extending flange, adjacent to which in the radially inward
direction is an area with an essentially V-shaped cross-section.
Said area encompasses an essentially axially extending annular part
12 with an indentation 13 on its outer side, whose radially outer
rim 10 forms the rim for application of the levering tool.
Indentation 13 is designed as a radially inward-pointing
right-angle bend of annular part 12.
[0041] Furthermore, the end of indentation 13 facing away from edge
area 8 of lid 2 displays a radially outward-facing annular
projection 14, the outer side of which transitions into an inwardly
inclined surface 15. An axial annular flange 16 is integrally
moulded on the end of inclined surface 15 facing axially away from
edge area 8 of lid 2. Extending from annular flange 16 is an
annular, conical area 17 that extends radially inwards, axially to
edge area 8 of lid 2 and essentially up to the level of edge area 8
of lid 2. Starting from its edge area 8, the cross-section of lid 2
is of essentially V-shaped design in the radially inward direction.
The V-shaped area transitions, via an essentially trapezoidal
section 18, into an axially inwardly offset, middle area 19 of lid
2.
[0042] Outer edge 7, and also part 11 of the edge of opening area 9
of lid 2 designed as a narrow web, has an outward, downward
inclination, as shown in FIGS. 6 and 7. The purpose of the inclined
design of edge 7 and part 11 is to ensure that a tool open to
consideration for levering open lid 2 cannot reach between opening
rim 6 of container opening 5, on which edge area 8 of lid 2 lies,
or from which it is separated by a very small gap, and outer edge 7
or part 11 of lid 2. The inclined design additionally prevents the
levering tool from acting on the upper edge of edge 7 in order to
lever open the edge area of lid 2 and enter the area between outer
edge 7 of lid 2 and opening rim 6 of container opening 5.
[0043] Lid 2 is connected to container 1 in the manner described
below, as can particularly be seen in FIG. 2.
[0044] The opening-side end of container 1 displays a separately
injection-moulded plastic frame 20, which is snap-fitted onto the
opening-side end of container 1. Frame 20 forms opening rim 6 of
container 1, which projects radially inwards from container wall 3.
Opening rim 6 is designed as an essentially radially extending
annular flange, the radially inner end of which transitions into a
conical flange part 21, which is inclined relative to container
bottom 4. Conical flange part 21 is a distance away from rim 10 of
lid 2, which is used for application of the levering tool, such
that the free end of the levering tool can be inserted between
conical flange part 21 and rim 10 and can be applied under rim 10.
Located on the end of conical flange part 21 pointing towards
container bottom 4 is a radially inward-pointing annular projection
22, which can be snapped into indentation 13 of axially extending
annular part 12 of lid 2. Projection 22 is designed with a T-shaped
cross-section, with a radially extending annular web and an axially
extending wider area, which snaps in between rim 10 and projection
14 of lid 2. Owing to the T-shaped design of projection 22, a gap
remains between rim 10 of lid 2 and conical flange part 21 of frame
20, through which the tool can extend to below rim 10 in order to
lever open lid 2.
