  • Two mutually releasably connectable members can be configured between a "connected configuration” and a "released configuration". In said released configuration, there is no longer a direct connection between the members involved. Preferably, in said released configuration, there is no longer a connection between the members involved.
  • at least one member of two mutually releasably connectable members provides some operable release mechanism, for releasing the members from their connected configuration.
  • the releasable connection mechanism comprises a screw coupling (releasable via a turning operation), a bayonet coupling (releasable via a turning operation), and/or a latch coupling (releasable via a pressing operation).
  • the invention concerns a lid assembly for a drinking container, the lid assembly comprising :
  • sealing assembly comprising a sealing assembly body and a sealing element which is moveable between a first position, in which the sealing element is positioned such that the drinking opening is closed, and a second position, in which the sealing element is positioned such that the drinking opening is open, and

  • the mounting member may be slidably connected to, and released from the lid housing.
  • the mounting member (as well as the sealing assembly pivotally mounted thereon) can be released from the lid housing. In doing so, the mounting member and lid housing are brought in their released configuration. This may allow for a more thorough cleaning.
  • the mounting member may comprise a mounting frame.
  • the mounting frame In their connected configuration, the mounting frame may be received into the lid housing.
  • the mounting frame may be slidingly received into the lid housing.

  • the outer size and shape of the mounting frame may substantially correspond to the inner size and shape of the side wall.
  • Latter shapes are preferably not entirely circular. By means of a non-limiting example, latter shapes comprise at least one complementary rib and groove, respectively.
  • the mounting member and lid housing can be releasable connected. In doing so, they are brought in their connected configuration.
  • the mounting member and lid housing are releasably connectable by means of one or more resilient elements.
  • at least one member of the mounting member and/or lid housing comprises one or more, resilient elements, biased for pressing against the other member.
  • said resilient elements are operable against the bias, for releasing the mounting member from the lid housing.
  • the sealing assembly comprises a sealing arm that is moveably mounted onto the sealing assembly body, and that is provided with the sealing element.
  • the sealing arm may have a rotational, translational, and/or a mixed rotational-translational degree of freedom with respect to the sealing assembly body.
  • a first degree of freedom corresponding to the sealing arm being moveably mounted onto the sealing assembly body substantially allows for moving the sealing element between its first (closed) and second (open) positions.
  • An advantage of the sealing assembly body being pivotally mounted onto the mounting member is that an additional, second degree of freedom is provided. The latter may allow for aligning the sealing element with the drinking opening. This is particularly advantageous in case of an inclined or non-centrally positioned drinking opening.
  • the second degree of freedom may thereby allow for pivoting the sealing assembly during (a) insertion of the mounting member into, and/or (b) removal of the mounting member out of the lid housing.
  • the sealing assembly body may thus follow a desired path, when displacing the mounting assembly w.r.t. the lid housing, e.g.
  • a first degree of freedom of the sealing arm w.r.t. the sealing assembly body is substantially addressed.
  • a second, pivotal degree of freedom of the sealing assembly body w.r.t. the mounting member is substantially addressed.
  • these first and second degrees of freedom are different in nature. As a consequence, the ease of insertion of the mounting member into the lid housing may be increased. Moreover, the ability of the mounting member to provide a rigid support to the sealing assembly may be increased, in the connected configuration.
  • the sealing arm is slidably (or telescopically) mounted onto the sealing assembly body, along a sealing axis.
  • the sealing member may be slidably supported and guided by the sealing assembly body.
  • latter (first) degree of freedom substantially corresponds to the sealing element being moveable between its first and second positions.
  • the sealing element when moving between its first and second positions, substantially travels along said sealing axis.
  • the sealing axis substantially extends through a center of the drinking opening.
  • the net force acting on the sealing element in its first, closed position is substantially pointing along the sealing axis.
  • the lid housing comprises a drinking spout.
  • the drinking opening extends through an upper portion of said drinking spout.
  • Such a design providing a high or raised user drink interface, allows the drinking opening to be placed near, or to be inserted into a user's mouth without obstruction.
  • the drinking spout may extend along a spout axis, towards the drinking opening.
  • the drinking spout may have a curved design.
  • the drinking spout may enclose a spout channel that connects to said drinking opening.
  • the sealing element is preferably capable of closing off the drinking opening, at or near an upper portion of the drinking spout.
  • complex mechanisms are required to provide a seal that can be opened and closed by a user, and such complex mechanisms can be expensive to manufacture.
  • the mechanisms are disposed within the interior of the lid housing, bacteria and debris may be difficult to remove therefrom.
  • the sealing arm extends into the drinking spout, in the connected configuration of the mounting member and lid housing.
  • the sealing arm may be an elongated member that is slidably/telescopically mounted onto the sealing assembly body, and fitted within the (elongated) drinking spout.
  • the sealing arm may thereby substantially extend along the aforementioned spout axis.
  • An advantage is that such designs are compatible with an elongated and/or narrow drinking spout; preferably the movement of the sealing element between its first and second positions, within the drinking spout, thereby substantially lies along the drinking axis.
  • the spout axis and the sealing axis are substantially parallel in the connected configuration.
  • the sealing arm comprises a sealing portion and an engagement portion.
  • the sealing portion thereby extends into the drinking spout; it is provided with the sealing element for closing the drinking opening at an upper portion of the drinking spout.
  • the engagement end portion on the other hand, is in connected configuration positioned at or near a lower portion of the drinking spout. As such, it may be more easily accessible for being engaged by the operating assembly.
  • An advantage is that the sliding/telescopic movement of the sealing arm, within a narrow/extended drinking spout can then be controlled at or near a lower portion of the drinking spout.
  • the lid assembly comprises a guiding means for guiding said sealing arm into and out of said drinking spout.
  • Said guiding means may greatly improve the ease of insertion of the mounting member and sealing assembly into the lid housing.
  • the guiding means may comprise a guide projection and/or a guide slot.
  • the guiding means may act as an alignment means, aligning the sealing element with the drinking opening upon insertion of the mounting member and sealing assembly into the lid housing.
  • at least the pivotal degree of freedom of the sealing assembly w.r.t. the mounting member is thereby addressed. More preferably, substantially only the pivotal degree of freedom of the sealing assembly w.r.t. the mounting member is thereby addressed.
  • the sealing element When receiving the mounting member and sealing assembly within the lid housing, through a sliding action substantially along their mutual height direction, the sealing element may then naturally align with the drinking opening, through a pivotal movement of the sealing assembly body w.r.t. the mounting member, further guided by said guiding means.
  • said guiding means are comprised by the sealing arm. Said guiding means may thereby additionally assist in guiding the sealing element between its first (closed) and its second (open) positions, within the spout channel. In particular, the guiding means thereby ensure that the sealing element is not hindered through interference with the spout wall enclosing the spout channel.
  • the spout somewhat runs towards the user of the drinking container.
  • the drinking spout extends along an inclined spout axis.
  • the inclined spout axis preferably has a spout angle smaller than 90°.
  • the spout angle is preferably between 0° and 89°, preferably smaller than 89°, preferably smaller than 88°, preferably smaller than 87°, and preferably larger than 30°. Even more preferably, the spout angle is substantially smaller than 90°; for instance it is equal to about 60°, about 70°, about 80°, or any value therebetween.
  • An advantage of the sealing assembly body having a pivotal degree of freedom w.r.t. the mounting member is that, upon connecting these members, the pivot angle may be continuously adjusted. This preferably corresponds to the sealing element advancing into the inclined spout channel. At the same time, the sealing member need not be moved along the exact same direction. For instance, it may be form-fittingly slid into the lid housing, along their mutual height direction. The mounting member can be installed into the lid housing in a straightforward fashion, even for spout angles that are substantially smaller than 90°.
  • Another advantage is that only one design of the interior mechanism (mounting member + sealing assembly) may be suited for cooperating with a number of lid housings featuring different spout angles. This increases its versatility.
  • the sealing assembly body is pivotable between a first, connected inclination and a second inclination.
  • the sealing arm In its first inclination, the sealing arm preferably extends into the spout channel.
  • the sealing axis may be substantially parallel to the spout axis.
  • Said second inclination may substantially differ from said first inclination.
  • said second inclination corresponds to an upward and radially inward inclination of the sealing assembly body.
  • the sealing assembly body is radially more compact. In this radially compact configuration, the internal mechanism (of the mounting member + sealing assembly) may easily be removed from the lid housing.
  • this is further explained in the embodiment of figure 2C. Of course, the invention is not limited to the latter.
  • the sealing assembly body is freely pivotable between the first and second inclinations.
  • a resilient member e.g. a torsion or compression spring
  • This may improve the ease of insertion of the mounting member into the lid housing.
  • the mounting member comprises an abutment portion for supporting the sealing assembly body in its first, connected inclination. Through this abutment portion, the mounting member may provide support to the sealing arm, (a) against the net sealing force acting on the sealing element and arm when residing in their first closed position, and/or (b) against the net force acting on the sealing element and arm, when operated by means of the operating mechanism.
  • the sealing axis and the pivot axis are mutually orthogonal.
  • the sealing assembly provides a force lever along the sealing axis, about the pivot axis.
  • a force acting on the sealing arm e.g. the net sealing force, when the sealing element is in its first position
  • the sealing assembly is thereby supported against said moment of force by means of the aforementioned abutment surface and/or by means of said guiding means.
  • Operating the operating mechanism then causes the sealing element to move between its first and second positions, while the pivotal movement of the sealing assembly w.r.t. the sealing assembly body is blocked.
  • the mounting member comprises a circumferential mounting frame, releasably connectable to a side wall of the lid housing.
  • a mounting frame may provide a more rigid support to the sealing assembly. Additionally, it may be more easily inserted.
  • the mounting member is releasably connectable to the lid housing by means of one or more resilient elements, biased for gripping a portion of the lid housing. Advantages thereof are mentioned above.
  • the mounting member may comprise two such resilient elements. Said elements may further comprise a contacting portion for pressing against the side wall of the lid housing, when the mounting member is connected to the lid housing.
  • the side wall of the lid housing may further comprise corresponding recesses for receiving latter contacting portions, when the mounting member is connected to the lid housing.
  • Latter contacting portions may further comprise at least one notch, for receiving corresponding protrusions on the side wall of the lid housing, when the mounting member is connected to the lid housing.
  • the invention concerns a drinking container comprising a container body, and further comprising a lid assembly as described above.
  • a drinking container comprising a container body, and further comprising a lid assembly as described above.
  • the present invention also provides an interior mechanism comprising a mounting member and sealing assembly, separate from any lid housing and operating assembly.
  • the sealing assembly is mounted onto the mounting member, and the mounting member is suitable for being releasably connected to the lid housing, within the lid housing.
  • said interior mechanism has a mounting member and sealing assembly, substantially corresponding to the ones described above. In this regard, the same characteristics and corresponding advantages may be repeated.
  • the interior mechanism may be connected to, and entirely released from a suitable lid housing. The latter is advantageous for cleaning.
  • FIGS 1A-B respectively show a lateral cross-section and a transverse cross- section of an embodiment of a lid assembly 1 in its (releasably) connected configuration, and mounted onto the top opening 61 of a container body 6.
  • Figures 1C-D show lateral cross-sections of the same lid assembly 1 and container body 6, when operating the operating assembly 40 to move the sealing element 21 from its first open position into its second closed position.
  • figures 2A-C show lateral cross-sections of the lid assembly 1, when releasing the releasably connected mounting member 30 from the lid housing 10. The lid assembly 1 is thereby brought in its (connectable) released configuration.
  • the lid assembly 1 comprises a lid housing 10 having an outer surface 11 that bulges radially outward, substantially along an upward inclined spout axis 126, thereby forming a drinking spout 123.
  • latter spout axis 126 forms a spout angle 125 with respect to the longitudinal direction L, substantially smaller than 90°. And substantially larger than 0°, preferably substantially larger than 45°.
  • a drinking opening 12 thereby extends through an upper portion of the drinking spout 123.
  • Latter drinking opening 12 is orthogonal to the spout axis 126; this is however not necessarily so.
  • a sealing element 21 is further provided, currently positioned such that the drinking opening 21 is closed.
  • the drinking opening 21 may give access to the holding volume of the container body 6, said access running through the spout channel 124, through and/or along the sealing assembly 20 and mounting member 30 (described hereunder), and via the bottom opening 15 of the lid housing 10.
  • the lid housing 10 comprises a downwardly extending side wall 13 that features an external screw thread 14', coacting with an internal screw thread 14 provided at the top opening 61 of the container body 6.
  • the lid assembly 1 further comprises a sealing assembly 20 having a sealing assembly body 22.
  • the aforementioned sealing element 21 itself is provided onto a sealing arm 24 that is slidably guided and supported by the sealing assembly body 22.
  • a compression spring 23 is further provided, biased for pressing the sealing element 21 against the drinking opening 12, in a first closed position of the sealing element 21.
  • the sealing arm 24 may be made to slide w.r.t. the sealing assembly body 22, along a sealing axis 243, and against the opposing force created by the aforementioned compression spring 23.
  • the sealing element 21 is thereby brought into a second open position, as shown in figure ID.
  • the sealing axis 243 is oriented parallel to the spout axis 126, with the sealing arm 24 extending into the spout channel 124, pointing towards the drinking opening 12.
  • the lid assembly 1 further comprises an operating assembly 40 for operating the above sealing assembly 20, thereby moving the sealing element 21 between the first closed and second open positions.
  • the operating assembly specifically comprises an actuator element 41, slidably received into the lid housing 10 through at least one actuator opening 16. It can be made to slide along a forward direction which may or may not (presently the case) be inclined with respect to the longitudinal direction L.
  • the actuator element 41 comprises an actuation portion 419 for contacting and for coacting with an engagement portion 246 present on the sealing arm 24. In its first rest position of figure 1A, the actuator element 41 is fully withdrawn into the backward direction. The actuator opening 16 is thereby sealed off by means of a first seal 43.
  • the actuator element 41 is however operable by means of a user operable contacting element, presently embodied by a pushbutton 42, and housed within an operating opening 181. A user 8 pushing the pushbutton 42 may thereby cause the actuator element 41 to be displaced into the forward direction, to a certain degree.
  • the actuator element 41 When relatively gently pushing the pushbutton 42, the actuator element 41 may be brought into an intermediate venting position.
  • the first seal 43 thereby loses contact with the actuator opening 16, as shown in figure 1C. Consequently, a pressure exhaust channel 7 is formed, such that any pressure difference between the holding volume and its surroundings may be restored.
  • said pressure exhaust channel 7 runs into a direction substantially radially opposite to the drinking spout 123. Indeed, in order to drink the drinking liquid, the user 8 will tip the drinking container 1, 6 such that he faces the drinking spout 123.
  • the drinking liquid surface then preferably levels such that the pressure exhaust channel 7 entry is no longer immersed in the liquid, as may have been the case for a flat storage of the drinking container 1, 6 into a handbag. Pressure differences may then be restored between gaseous phases inside and outside the container 1, 6. Furthermore, in doing so, the actuation portion 419 does not or only just engage the engagement portion 246 of the sealing arm 24; in any case, the sealing element 21 substantially remains in its closed position.
  • the actuator element 41 When further pushing the pushbutton 42, the actuator element 41 may be brought into a second opening position. A second seal 44 thereby contacts the actuator opening 16, cutting off the pressure exhaust channel 7. This is shown in figure ID. Simultaneously, the actuation portion 419 of the actuator element 41 coacts with the engagement portion 246 of the sealing arm 24, such that the sealing arm 24 is withdrawn along the sealing axis 243, away from the sealing opening 12. I.e., the sealing arm 24 is pushed away from the drinking opening 12, by means of the actuator element 41 and its actuation portion 419. The sealing element 21 is thereby brought into its second open position.
  • the sealing arm 24 comprises a passage 245 through which an actuator end 418 of the actuator element 41 may extend.
  • the actuation portion 419 of the actuator element 41 forms downward facing surface.
  • Latter surface when sliding along and off an upward facing surface (i.e. the engagement portion 246) formed by the sealing arm 24, within the same passage 245, causes the sealing arm 24 to move down.
  • At least one of both surfaces comprises an surface portion that is inclined with respect to the sealing axis 243. Only optionally, the actuator element 41 will in its maximum forward position contact a stop portion 224 of the sealing assembly 20.
  • the user 8 may now sip the drinking liquid from the drinking container 1, 6 as it exits the drinking opening 12 (e.g. when tipped - not shown). Since any pressure differences have been leveled, prior to actually opening the drinking opening 12, he does not risk drinking liquid of being unexpectedly forced through said drinking opening 12.
  • Another compression spring 45 is further provided, biased for returning the actuator element 41 into its original first position when releasing the pushbutton 42. The sealing element 21 then simultaneously returns to its first, closed position (as shown in figure 1A).
  • the lid assembly 1 further comprises a separate mounting member 30, onto which mounting member 30 the sealing assembly body 22 is pivotally mounted, about a pivot axis 34.

  • the mounting member 30 is releasably connected to, and releasably locked into the lid housing 10.
  • the mounting member 30 comprises a resilient element 31 featuring a contacting portion 313 that forms a locking tab 314.

It has a first leg 311 extending from the joint 317, towards an operating portion 315, and a second leg 312 extending from the joint 317, towards the aforementioned contacting portion 313.
  • the resilient element 31 When pulling the operating portion 315 in a downward direction (e.g. downwardly, substantially along the height direction H), the resilient element 31 may be tilted with respect to the mounting frame 33, about its thin joint 317. In doing so, the locking tab 314 may be unlocked from the locking edge 138, which situation is shown in figure 2A.
