Description
TITLE
Container closure
TECHNICAL FIELD
The present invention. s to a container closure
for closing a vessel. The closure has a pouring opening
which is closable via a e lever having a closure
body, said closure lever being operable in a vertical
direction.
PRIOR ART
Document discloses a beverage container
in the form of what is known as a “French press”. For
the preparation of, for example, coffee or tea in this
ge maker, a filter piston is inserted into the
vessel and pressed down such that a plunger filter
separates the prepared beverage from the depleted
coffee powder or the tea . In order to reduce the
risk of the user being scalded by hot liquid Spurting
out when pressing down the filter piston, a closure in
which a pouring g is closable by a e body
d on a closure lever is disclosed in said
document. By pivoting the spring—loaded closure lever,
the pouring opening is uncovered in a simple manner and
the beverage which is held in the vessel of the
3O beverage container can be poured.
It is disadvantageous in the case of the above—
mentioned container closure having a closure lever that
a pressure has to be d continuously to the
closure lever during the pouring of the beverage in
order to hold said closure lever in the opening
position counter to the spring force. This is
particularly inconvenient when pouring continues for a
comparatively long time. By way of example, this is the
case when the beverage located in the container is
provided for a multiplicity of people who have to be
served immediately after one another, such as is often
the case in hospitality establishments or in the
catering e for airline passengers.
In documents US 2004/0108336 and DE 295 04 343,
container closures are in each case disclosed in which
the e lever can be d in its opening
position. In US 2004/0108336, a sliding t is
provided on the closure lever for this purpose, said
sliding element pressing the closure lever, in the
opening position, upward counter to a downwardly
ed spring force by means of a stop. In the case
I5 of DE 295 O4 343, a spring lever locks the closure
lever in the opening position. In order to return the
closure lever back to the closing on, a release
lever is activated which pushes the spring lever away
from the closure lever.
These two container closures described, in which the
closure lever is blockable in its opening position, are
manufactured in a relatively elaborate manner, since in
each case additional components are required for
providing the blocking function.
DESCRIPTION OF THE INVENTION
It is therefore an object of the present invention to
3O provide a container closure (lid) which is as simple as
possible to manufacture and in which a closure lever is
blockable in its g position in a simplest
le manner, or to at least e the public with
a useful alternative to known container closures.
This object is achieved by a container closure for
closing a vessel (2) with a vessel
interior (23), having a pouring opening (37)
which. serves to form. a fluid communication. from the
vessel interior (23) to the outside for pouring liquid
from the vessel (2); a e body (36) by means of
which the pouring opening (37) is closable; and a
closure lever (33) which interacts with. the closure
body (36), said closure lever having an operating
region (331) which is operable by pressure of a finger
of the user in a chlection of operation in order to
pivot the closure lever (33) from a closing position,
in which the closure body (36) closes the pouring
opening (37), to an opening position, in which the
closure body (36) uncovers the pouring opening (37),
characterized. in that the container closure (3) also
has a rotating t (31) which is rotatable in
relation to the closure lever (33) about an axis which
extends in approximately the same direction as the
direction of operation, in order to form a stop with
the closure lever (33) in a blocking position and thus
to block the closure lever (33) in its opening
position, and, in a releasing position, to permit
pivoting of the closure lever (33) between the closing
position. and the opening‘ position and. by‘ a beverage
container having a vessel (2) with a vessel bottom and
an encircling side wall (21), and having such a
container e. r embodiments are specified
herein.
Indications of location and direction, such as up,
down, upward, vertical etc. relate in each case to a
3O beverage ner standing upright having a vessel in
which. a beverage is held and which. is closed. by a
container closure according to its intended. use. The
vessel usually has a substantially cylindrical shape,
or has at least a substantially round cross section,
and further has an upper, y round vessel opening.
The container closure is usually adapted to the vessel
opening and thus also y has a round basic shape
which defines a radial direction, a circumferential
(followed by page 3a)
-3a-
direction, and a longitudinal axis which is
perpendicular to said circumferential direction. The
vertical direction then usually extends in the
ion of gravity. One direction extends
transversely to r direction when the angle formed
in between is at least 45°, preferably when the
directions are even substantially perpendicular to one
another.
The present invention thus provides a container closure
for closing a vessel having a vessel interior, in
particular for the fluid—tight closing of said vessel,
having:
a pouring opening which serves to form a fluid
communication from the vessel interior to the outside
for pouring liquid from the ;
a closure body by means of which the pouring opening
2O is le; and
a closure lever which cts with the closure body,
said closure lever having an operating region which is
operable by pressure of a finger of the user in a

-4:—
direction of operation in order to pivot the closure
lever from a closing position, in which the closure
body closes the g opening, to an opening
position, in which the closure body uncovers the
pouring opening.
The container closure moreover has a rotating element
which. is rotatable in relation. to the closure lever
about an axis which s in approximately the same
direction as the direction of operation, in order to
form a stop with the e lever in a blocking
position and thus to block the closure lever in its
opening position, and, in a releasing position, to
permit pivoting of the closure lever between the
closing position and the opening position.
In a container closure of such a type, the user thus
operates a e lever in order to open the pouring
g and to pour the beverage held in the vessel. In
order to block the closure lever in the opening
position, the rotating element is rotated into the
ng position, in which it forms a stop with the
closure lever in order to block said closure lever. The
blocking in this case refers to the fact that the
closure lever cannot be moved into the closure position
any more. In order to pour a beverage, the user can
hold the beverage container with one hand on a
preferably provided hand grip, move the closure lever
with, for example, the thumb of the same hand into the
opening position and rotate the rotating element with
the other hand in order to block the e lever and
to uently pour the beverage.
The operation of such a container closure is thus
simple and intuitive. Moreover, a container closure
formed in such. a manner allows simple manufacturing
from as few individual components as possible.
- 5 —
Preferably, the container closure as a whole represents
a stand—alone element which serves to close a vessel
which is formed tely from said container closure.
The container closure in this case is preferably
insertable into an upper vessel opening of the vessel.
In ative ments, the container Closure may,
however, also be formed as one unit or at least even be
in part formed integrally with the vessel. By way of
example, the pouring opening may be defined by the
actual vessel.
The closure lever may interact with the closure body in
any desired manner. The closure body may in particular
and preferably be mounted directly on the Closure
lever.
The operating region of the closure lever may be
operable in principle in any desired direction of
operation; it is, however, ably operable
ntially in the vertical direction (in the sense
of the above—defined ional notes). The operating
region is in particular preferably operable in such a
manner that it has to be pressed downward to open the
pouring opening. The closure lever is then easily
retainable in its opening position, for example, with
the thumb while the beverage is being poured, when the
ng element is not in the blocking position. In
the blocking position, the rotating element of a
e having' a closure lever‘ which. is operable in
3O such a manner forms an upward stop (i.e. in the
direction counter to the direction of ion), and
therefore preferably has a stop element which protrudes
downward (i.e. in the direction of operation). The
rotating element advantageously forms the stop with the
operating region of the closure lever or with a region
of the closure lever which is located immediately
nt to the operating region. The blocked state of
WO 29712 — 6 —
the closure lever in the opening position is then
particularly clearly visible to the user.
The closure lever is advantageously spring loaded in
the direction of its g position. In the releasing
position of the rotating element, the pouring opening
is automatically closed when the closure lever is not
ed by the user. A compression spring is
preferably used for this purpose.
Li a particularly preferred embodiment, the container
e has a retaining structure which is attached to
a region of the container closure in relation to which
the rotatable element is rotatable between the blocking
position and the releasing position. In this
embodiment, the rotatable element has an engaging
structure which, in the blocking position, interacts
with the retaining structure in such a manner that a
movement of the rotatable element counter to the
direction of operation in relation to said region is
prevented. The retaining structure and the engaging
structure thus prevent, ularly in the case of a
spring—loaded closure lever, said closure lever from
pushing away the ng element in the direction of
operation, as a result of its spring force, in the
blocking position. l of the rotating element from
the closure for example for cleaning purposes is,
however, still readily possible by placing the rotating
t in the releasing position.
The retaining structure and the engaging structure
preferably form a rotating limit stop in the blocking
position. An excessive rotation of the rotating element
beyond the provided ng position is prevented as a
. The retaining structure and/or the engaging
structure may, in particular, be L—shaped for this
purpose. One arm of such an L—shaped retaining
ure or ng structure in this case preferably
WO 29712 — 7 —
extends in the circumferential ion. and. forms a
guide for the engaging or retaining structure when the
rotating element is rotated into the blocking position.
In the blocking position, this arm extending in the
circumferential direction serves to hold back the
rotating element with respect to a movement in the
ion. counter to the direction. of operation” The
other arm preferably extends in the direction of
operation and forms a stop for the engaging or
retaining structure in the circumferential direction.
The engaging structure and the retaining structure may
moreover also be formed to enter into a bayonet
connection with one another in the blocking position.
In a preferred embodiment, the container closure has a
cover wall, inside of which the pouring opening is
d. The cover wall is formed to at least partially
cover the vessel toward the top in order, jointly with
the vessel, to delimit the vessel interior. The cover
wall particularly preferably even completely covers the
vessel toward the top, with the exception of the
pouring opening. The cover wall preferably extends
substantially in a horizontal plane.
The closure lever is preferably mounted above the cover
wall. It is advantageously located below the ng
t in this case, that is to say between the
rotating element and the cover wall. It may, in this
case, be ble in principle about any desired axis;
however, it is preferably" pivotably mounted. about a
horizontal axis.
ha a particularly preferred embodiment, the ner
closure comprises a lower part which forms the cover
wall, and an upper part which is formed separately from
said lower part and which at least partially, but
advantageously entirely, covers the lower part and the
e lever, said upper part being rotatable in
relation to the lower part and forming the rotatable
element. Preferably, the upper part and lower part are
rotatably connected to one another in a central region.
In the event of a retaining structure being provided,
said retaining structure is preferably located on the
outside of the lower part. The retaining structure, if
providedq is preferably' located. on a surface of the
upper part which faces ly inward.
The upper‘ part ably’ has a downwardly‘ extending
link which in the blocking position forms a stop with
the closure lever. If a retaining ure is
provided, said retaining structure is preferably
located on the link and particularly preferably in a
lower region of the link.
The lower part preferably has a radial ery, and
the link is located outside of said radial ery in
the radial direction. The lower part advantageously
also has an encircling side wall which s upward
from the cover wall, said side wall forming the radial
periphery. A recess for the closure lever may be
provided in the encircling side wall. Moreover, a spout
is advantageously formed in this side wall.
Furthermore, the present invention provides a beverage
container having such a container e. The beverage
container moreover has a vessel with a vessel bottom
3O and an encircling side wall.
The ge container is preferably a beverage maker
having a filter piston which is vertically movable in
the vessel and which has a piston rod which penetrates
through the container closure. The piston rod
preferably also penetrates through the closure lever in
this case.

In the event of the container closure having a
retaining structure, said retaining structure may in
particular also be located on the vessel or on a vessel
holder in which the vessel is held.

PTION OF RED EMBODIMENTS
In figures 1 to 5, a preferred ary embodiment of
a lid 3 according to the invention is shown in
different illustrations. In this exemplary embodiment,
the lid 3 forms, together with the vessel 2 into which
said lid 3 is inserted and which is closable by the lid
3, a beverage container in the form of a coffee
plunger. The embodiment shown in figures 1 to 5
represents a further development of the beverage
container from document , the disclosure
content of which is herewith expressly incorporated by
way of reference into the present description.
The beverage maker comprises a holder 1 made of
plastic, a substantially cylindrical vessel 2 which is
held n, a lid 3 and a filter piston 4. The vessel
2 may' be transparent and consists in particular of
heat—resistant glass; it may, however, also consist of,
for example, plastic or metal.
The holder 1 comprises an upper ing ring 12,
which encircles the side wall 21 of the vessel 2, and a
lower retaining ring, not visible in the figures, which
merges into a bottom which is rdly perforated by
a circular central opening. The retaining rings are
connected to one another by two udinal braces 13
and 14 which extend in the longitudinal direction of
the vessel. A. hand. grip 15 for holding the ge
maker is also connected to the upper retaining ring 12
and the lower retaining ring 15.
The upwardly open vessel 2 consists of a bottom, which
may be slightly arched upward, and an encircling side
wall 21 having a circular cylindrical basic shape. As
opposed to most of the coffee makers according to the
prior art, no spout is formed in the side wall. The
— ll —
side wall 21 terminates just below the upper rim of the
upper retaining ring 12 of the holder 1.
The container closure or lid 3 is inserted into the
vessel 2. Said lid 3 is of ece design and
comprises a lid lower part 32 and a lid upper part 31.
The lid lower part 32 has a ntially planar cover
wall 321 which extensively covers the upper vessel
opening and, together with. the vessel 2, ts a
vessel interior 23. A g opening 37 is formed in
the cover wall 321, said pouring opening 37 being
visible in figures 3 and 4. In figure 3, the pouring
opening 37 is closed in a sealed manner by a e
body 36 in the form of a stopper.
Starting from the cover wall 321, a cylindrical side
wall 327, which is interrupted by a beak—like spout 328
and by a cutout for a closure lever 33, extends upward
from the outer rim of said cover wall 321. Also
starting from the cover wall 321, an encircling,
cylindrical skirt 325 having a slightly smaller
diameter extends downward into the vessel 2. From the
skirt, a pair of annular, —apart webs extend
outward and form a mounting for an encircling, annular
seal 35 having a radially' outwardly protruding seal
lip. Thus, on the one hand, the lid 3 is held
relatively tightly in the vessel 2 after having been
inserted, and, on the other hand, a seal between the
vessel and the lid is formed which. prevents liquid
3O leaking between vessel and lid.
The closure lever 33 of elongate shape is pivotably
mounted. on. the lid lower‘ part 32. For this purpose,
said closure lever 33 has two laterally protruding,
coaxial, horizontal bearings pins, not shown in the
drawings, on a central main section 332, said bearing
pins being clicked into two mouth—shaped bearing
elements which are open toward the front, i.e. in the
— 12 —
direction of the spout 328, said g elements also
not being visible in the drawings.
In the forward end region of the closure lever 33 which
faces the spout 328, a round opening is formed, into
which the e body 36 is inserted. Whilst the
actual e lever 33, like the rest of the lid, is
made of an impact—resistant and relatively hard
plastic, such as, for example, polypropylene, the
closure body 36 is made from a comparatively soft
material, for example silicone c, in order to
achieve a good sealing .
At the rear end of the closure lever 33 which faces
away from the spout, said closure lever 33 protrudes
radially out of the lid lower part 32 with an operating
region 331 and can be easily pivoted about its
horizontal pivot axis by being pressed downward (i.e.
in a direction of operation) by the thumb of the user,
such that the closure body 36 is lifted from the
pouring opening 37 and reveals the g opening. The
closure lever 33 is thus in an opening position. as
shown in figures 2 and 4.
By means of a coil spring 34 which acts by compression,
the lever is pre—tensioned toward the closing position.
The coil spring 34 is located in the rear region of the
lever which faces away from the spout, but is still
located within the side wall 327 of the lid lower part.
3O The spring is held in a aped depression 324 of
the cover wall 321, this enabling a spring travel which
is greater than would be possible without such a
depression. In the upward direction, the spring engages
in an annular spring seat 333 on the underside of the
closure lever 33. On account of the depression 324 and
the spring seat 333, the spring is secured against
lateral displacement or even jumping out. In the
closing position of the closure lever 33 shown in
- l3 -
figures 1 and 3, the e body 36 thus closes the
g' opening' 37 in. particular‘ as a result of the
spring re which is exerted by the coil spring 34
on the closure lever 33.
The lid upper part 31, which is shown in particular in
figure 5, covers with. its upper cover wall 311 the
upper rim of the side wall 327 of the lid lower part
32. Starting from a central opening of the upper cover
wall, a guide bush 312, which is integrally formed in
the upper cover wall, extends vertically downward, the
piston rod 41 of the filter piston 4 being guided in
said guide bush. The e lever 33 and the lower
cover wall 321 of the lid lower part 32 each have a
nce opening through which the guide bush 312
s. In this case, the clearance opening of the
closure lever 33 is sufficiently large not to
compromise the pivoting movement of the lever. The
clearance opening of the lower cover wall 321, however,
is a custom fit for the guide bush 312. In the region
of the lower end of the guide bush, a plurality" of
flat, spherical—segment—shaped latching pins are formed
on the surface of the guide bush (not visible in the
drawings) which fonn a able latching connection
between guide bush 312 and lid lower part 32 after the
guide bush has been inserted. In this way, the guide
bush. is secured at two different vertical locations
against lateral displacements and thus against tilting
movements. This not only improves the vertical guidance
3O of the piston rod 41 but also diminishes the risk of
the connection between the upper cover wall 311 and the
guide bush 312 breaking. The cover upper part 31 and
the cover lower part 32 are thus particularly connected
to one another in such a manner that they are rotatable
in relation to one another about the vertical axis.
A link 313 extends downward from the outer rim of the
cover wall 311 of the lid upper part 31. In the
— l4 — 2012/000047
circumferential direction, the link 313 is ured
to be somewhat longer in comparison with the width of
the closure lever 33 in the region. of its operating
region 331. In alternative embodiments, however, the
link could be configured to be substantially longer and
extend over almost the entire circumference of the
cover wall 311. In the vertical ion, the link 313
is configured to be approximately as long as the height
of the side wall 327 of the lid lower part 32. As is
lO shown in s 1 and 2, the link 313 is located in
the radial ion on the outer side of the side wall
327 which. forms a radial periphery' of the lid lower
part 32. The position of the link 313 in the
circumferential direction in relation to the lid lower
part 32 and. particularly' to the closure lever 33 is
thus readily identifiable at any time by the user.
The lid upper part 31 having the link 313 is rotatable
in relation to the lid lower part 32 and the closure
lever 33 attached thereto in such a manner that it has
a blocking position, as shown in figures 2 and 4, which
blocks the closure lever 33 in its opening position.
The link 313 here forms an upper stop for the closure
lever 33 in the ate vicinity' of the operating
region 331, thus preventing pivoting of the closure
lever 33 back into its closing position. As a result,
the user can comfortably pour the beverage contained in
the vessel 2 t having to exert any pressure on
the operating region 331 of the closure lever 33. By
3O turning back the lid upper part 31 into the releasing
position shown in figures 1 and 3, pivoting of the
closure lever 33 back into the closure position is
enabled again.
Starting from that vertical edge of the link 313 which,
in the releasing position shown in figure 1, faces away
in the circumferential direction from the operating
region 331 of the closure lever 33 and toward the spout
— 15 —
328, an ng structure 314 extends along the lower
edge of the link 313. In comparison to the link 313,
however, the engaging structure 314 extends across a
substantially smaller angular region. The engaging
structure 314 located on the radial inner side of the
link 313 is configured to engage with a retaining
structure 329 in the blocking position of the lid upper
part 31, said retaining structure 329 being located on
the radial outer side of the side wall 327 of the lid
lower part 32 in a region next to the cutout for the
closure lever 33. This engagement has the effect that
the lid upper part 31 is not pushed away upward in the
vertical direction in the blocking position as a result
of the spring force of the compression spring 34. The
engaging structure 314 and the retaining structure 329
thus secure the lid upper part 31 in the blocking
position on the lid lower part 32.
As in the present exemplary embodiment, the retaining
2O structure 329 may be configured in an L—shape and form
a stop for the engaging structure 314 in the
circumferential direction. In this way, excessive
rotation of the lid upper part 31 beyond the blocking
on is prevented. The edge of the engaging
structure 314 which faces in the circumferential
direction toward the retaining structure 329 may also
be formed in a sloped manner in order to prevent
ntional latching n the retaining structure
329 and the engaging structure 314 when the lid upper
3O part 31 is rotated. in the direction. of the blocking
position. Alternatively, the retaining ure 329
and the engaging structure 314 may also form a bayonet
connection with one another in the blocking on.
The filter piston has a button 42 as an operating
element at the upper end of the piston rod 41. A
plunger filter not shown in the figures is d at
the lower end of the piston rod, said plunger filter
— 16 —
being of any desired, already known design. In
particular, such filter pistons having plunger filters
are often seen in beverage makers known as “French
presses” and many different configurations thereof have
therefore been known for a long time.
The invention is, of course, not limited to the
aforementioned example, and a multiplicity of
modifications are le. Thus, the e lever, in
particular, may be configured differently in terms of
its shape and arrangement. By way of example, the
'operating region need not be located radially outside
of the lid lower part, but may also lie within the lid
lower part and be accessible from above h a
cutout or opening in the lid upper part. Instead of a
link located on the outer rim, the lid upper part may
then, for example, have a downwardly protruding t
which is located within the side wall of the lid lower
part, said element forming, in the blocking position, a
stop with. the closure lever. In. place of the vessel
holder illustrated in the drawings, any desired other
holder may be used, or the holder may also be entirely
dispensed with, for example when the vessel has an
integral holding grip. Despite this not being
red, at least one part of the ner closure
could also be integrally formed with the vessel or the
vessel holder. For example, the lid lower part of the
embodiment shown in figures I to 5 could be integrally
formed with the vessel or the vessel holder. A
3O multiplicity of r modifications is possible. In
particular, it goes without saying that the mechanism
of the Closure lever for closing and opening the
pouring opening could be ured entirely
differently and be independent of the blocking function
of the lid upper part in on to the opening
position of the closure lever. Thus, for example, it is
not mandatory for the Closure body to be located on the
closure lever. The closure lever could, for example,
— l7 -
also interact indirectly with the closure body, as is
the case, for example, with the beverage ners
described in the documents US 2004/0108336 and
DE 295 04 343. The pouring opening could also be formed
in the region of the side wall of the lid lower part,
and the closure lever could be pivotable about a
vertical axis and accordingly be operable in the
circumferential direction. instead. of in the vertical
direction. The rotating element would then, together
with the e lever, form a stop in the
circumferential direction to block said closure lever
in the opening position. Of , the filter piston
may be dispensed with.
