Description
- The invention relates to a lid for a liquid container to substantially seal a container.
- When having children around, the chance of the child having an accident is substantial. One category relates to accidents with hot liquids such as hot coffee or tea. Especially little children tend to grab any object within their reach to examine the object. If a parent places a cup of hot coffee or tea onto a table while holding the child, it is possible that the child will try to grab the cup of hot liquid. If liquid is spilled it could come in contact with the child's skin, causing burns.
- It is therefore of advantage, when the cup with hot liquid can be sealed by a lid and it is still possible to drink out of the cup without having to operate the cup with two hands. This is in particular of advantage when holding a child.
-
WO-A-02/11587 - It is now an object of the invention to provide for a lid according to the preamble which improves the known
- This object is achieved by a lid comprising:
- a mounting frame for mounting the lid to the container, the frame having at least one passage opening for passage of the liquid in the container;
- a valve portion for closing the at least one passage opening of the mounting frame;
- a lip-operable operating portion for operating the valve portion; and
- spring means for urging the valve portion to a closing position, in which the at least one passage opening in the mounting frame is closed.
- With the lid according to the invention separate parts are provided, such that the functions can be separated. The valve portion can be designed to effectively seal the lid, the lip operating portion can be optimally designed for operation by lips and the spring means can be designed to have an optimal spring function and to urge the valve portion to a closed position. It is no longer necessary, as with the prior art to combine all these functions in just one single element.
- In an embodiment of the lid according to the invention, the spring means are arranged between the mounting frame and the valve portion. These spring means urge the valve portion to a closed position and it is of advantage when the spring means are arranged between the mounting frame and the valve portion in order to be able to design the springs optimally for the function of urging the valve portion to a closed position.
- Preferably the spring means comprise leaf springs which are easy to manufacture and provide a sufficient flexibility in combination with spring force for urging the valve portion to a closed position.
- In a preferred embodiment of the lid according to the invention, the valve portion is arranged to the spring means movable between a fixed position, wherein the valve portion is fixed to the spring means, and a loose position, wherein the valve portion is loosely attached to the spring means.
- As the lid is generally arranged to containers comprising a liquid and the liquid is emptied from the container through the lid, the lid gets dirty. In order to be able to clean the lid thoroughly it is necessary that all parts of the lid can either be disassembled or be brought into such a position that no small spaces remain and the remaining portions can easily be accessed by the cleaning action.
- Now by arranging the valve portion movable to the spring means it is possible to bring the valve portion into a loose position in respect to the spring means such that the valve portion is no longer urged to the closed position and the full surface of the valve can be cleaned. The valve is no longer urged in contact to a valve seat.
- In another preferred embodiment of the lid according to the invention the valve portion and operating portion are slidable arranged to each other between a first position and a second position, wherein the spring means are arranged in between the operating portion and the valve portion, such that in the first position the valve portion is fixed through the spring means and the operating portion and in the second position the valve portion is loosely attached to the spring means and the operating portion.
- In this embodiment the spring means are in fact clamped between the operating portion and the valve portion resulting in a fixation of the spring means to the valve portion. In the second position this clamping action is removed such that the elements of the lid are loosely connected and as a result can easily be cleaned.
- In yet another embodiment of the invention, the lid further comprises blocking means for blocking the slidable movement from at least the first position. These blocking means ensure that the operating portion and valve portion can only be brought from the first position to the second position when unblocking this movement.
- In a very much preferred embodiment of the lid according to the invention the blocking means comprise a flexible element arranged between the valve portion and the operating portion, which flexible element has a bivalent shape for urging the valve portion and operating portion in either the first position or the second position. With this flexible element having a bivalent shape the lid can easily be put from a first position to a second position or the other way around. This enables the user to simply deform the flexible element into the other shape. So when using the lid on a cup, the flexible element is put in the shape, such that the valve portion or operating portion are in the first position and when putting the lid in for example a dish washer, the flexible element is put in the second position such that all elements of the lid are loose and cleaning is easily performed.
- The invention also relates to a combination of a lid according to the invention and a liquid container. Preferably the lid is mounted to the container by screw thread arranged on the outside of the mounting frame. A seal can be provided near the screw thread such that the lid does not leak contents from the container along the screw threads.
- These and other advantages of the invention will be elucidated in conjunction with the accompanying drawings.
-
Figure 1 shows a perspective view of a combination according to the invention. -
Figure 2 shows in perspective view the combination offigure 1 in exploded view. -
Figure 3 shows in perspective view with cutaway portions the combination offigure 1 . -
Figure 4A-4C show three cross-sectional views of the combination offigure 1 in three different positions. -
Figure 1 shows a combination 1 according to the invention. This combination 1 has acontainer 2 with ahandle 3 onto which alid 4 is mounted. - In
figure 2 the combination 1 is shown in an exploded view. Thecontainer 2 has anopening 5 with aninternal screw thread 6. Onto thisscrew thread 6 thelid 4 is mounted. As also shown infigure 3 thelid 4 comprises a ring-shaped mounting frame 7 which is also provided with a screw thread 8 which cooperates with thescrew thread 6 in theopening 5 of thecontainer 2. - In order to seal the
mounting frame 7 with respect to thecontainer 2 an O-ring 9 is provided. - In the mounting frame 7 a spider like
spring element 10 is arranged. Thisspring element 10 has a number ofleaf springs 11 which are radially arranged. Due to the arrangement of this spider like spring element openings are present between theleaf springs 11 enabling content from thecontainer 2 to flow through themounting frame 7. - A lip
operable operating portion 12 is inserted into the spider likespring element 10. At the bottom of this spring element 10 avalve portion 13 is arranged, which seals off against themounting frame 7. - The
operating portion 12 andvalve portion 13 are connected to each other by aflexible ring 14. Thisflexible ring 14 has a bivalent shape which will be elucidated here below. - Furthermore, the
lid 4 comprises ahousing ring 15 which contributes to the appearance of the combination 1 and also improves the drinking experience from the combination 1. - The
valve portion 13 has a central protrusion which is provided byopenings 16. Theseopenings 16 are sealed off by theflexible element 14 and ensure that any cleaning action reaches the space between theflexible element 14 and thevalve portion 13. - In
figure 4A the combination 1 is shown in cross-sectional view. From this figure it is clear that theopening 16 provide access to thespace 17 between thevalve portion 13 and theflexible element 14. - Now referring to
figure 4B , when the operatingportion 12 is operated by the lips of a user by exerting a force F to the edge of this operatingportion 12, theleaf springs 11 will deform such that thevalve portion 13 moves away from theseat 17 at the mountingframe 7 such that anopening 18 is obtained and liquids L can flow through the lid into the users mouth. - In
figure 4B and4A theflexible element 14 is shown in its first shape. Infigure 4C theflexible element 14 is put into its second shape resulting in that thevalve portion 13, theleaf springs 11 and the operatingportion 12 are in a loose position such that sufficient space is present between the elements and the elements can easily be cleaned in for example a dish washer. - In the operating portion 12 a
small opening 19 can be provided in order to compensate for any pressure difference between the content of thecontainer 2 and the outside. In particular with hot liquids the pressure could rise within the container such that thevalve portion 13 cannot be operated any more. By providing such apassage 19 pressure is always compensated and thevalve portion 13 can easily be operated.
