The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
- In the following description, numerous specific details are set forth to provide a thorough understanding of the invention. However, it is understood that the invention may be practiced without these specific details. In other instances, well-known structures and techniques known to one of ordinary skill in the art have not been shown in detail in order not to obscure the invention. Referring to the figures, it is possible to see the various major elements constituting the apparatus of the present invention.
- The purpose of the present invention is to give a closure the ability to be opened with the same natural motion used to close it, you push it to close, you push it again to open it.
- The present invention is based on a
conventional latch 16 mechanism to which the inventors have added a second rotatingtongue 19 that will disengage themain latch 16. Thistongue 19 is moved in place by pressing on the lid 10 a similar way as to close it. It allows for the design team to have a much wider freedom of designing the closure, without the need to have an area dedicated for the pop-up activation device, reducing mold complexity and cost at the same time. - The present invention allows the
lid 10 to be open by a very simple push down motion. It also requires the user to reach a certain amount of force to open it avoiding accidental opening in case the closure fall on the ground. - Compared to button activated, the present invention uses a much more human and natural approach. The present invention works on the user reaction and the simplicity of the product. The design is done in a way with a slightly
recess lid 10 so that it leads the user to push on thelid 10. - The present invention is composed of one
lid 10 and abase 12, attached together by means of one or several living hinge or other fastening method. Thelid 10 andbase 12 can be obtained through one or several phase of plastic injection molding. Aspring 13 is present in order to store energy while thelid 10 is closed. Adisengaging tongue 19 is connected to thebase 12 near thelatch 16 mechanism. It can be connected to thebase 12 with a living hinge or other fastening method. - The
lid 10 is assembled to acover 11 through a living hinge or other fastening method, thelid 10 can then pivot around an axis, thebase 12 has a reach-inarea 14. When thelid 10 is closed, it should cover 11 a maximum of the reach-inarea 14 in order to provide a good moist sealing. Thetongue 19 is articulated around thebase 12 and close to thelatch 16 so that the extremity with the disengaging feature is beneath themain latch 16 mechanism. - When the
lid 10 is open, the user close it by simply pushing on it until he hears a click meaning that thelatch 16 has engaged. In the same time, thelid 10 will fold aspring 13 to store energy. Thelid 10 is closed. When the user wants to open thelid 10, he simply push thelid 10 further down, thelatch 16 will engage with the disengaging feature of thetongue 19, the user should hear a click meaning that it has engaged. The user release the push force on thelid 10 and thespring 13 will start to push on thelid 10, while thelatch 16 is going up, it will hit the main latch retaining feature on thebase 12 but cannot engage with it as it is obstructed by the disengaging feature of thetongue 19. Thelid 10 will then continue its opening course, the disengaging feature is design such that the spring force is enough to disengage thetongue 19 retaining feature, thelid 10 can now fully pop open. - Now referring to
FIGS. 1-2 , thelid 10,base 12 and thetongue 19 with its disengaging feature, the reach-inarea 14, the main retaining feature and thespring 13 are shown. The user pushes on thelid 10 to close it on thebase 12, and pushes it again to pop it open. -
FIG. 2 illustrates a moist toilet tissue tub, comprised of: a base 12; acover 11; a reach-inarea 14; afront cover 11 latch for the user to open thecover 11 and refill the tub; a fastening feature that thelid 10 latch hook on to keep thelid 10 closed; aspring 13 to accumulate elastic energy in order to move thelid 10; a thelid 10 articulated with thecover 11. - Now referring to
FIG. 3 , a closer view to thetongue 19 mechanism, from the top of the tub is shown. Thelatch retaining lip 18 is integrated to thecover 11 and acts as a main fastening feature to hold thelid 10 when closed. Thetongue 19 is located by throughholes 20. -
FIG. 4 is a section view of the tub when the pop-uplid 10 is in a closed position and the latch is engaged 21. Thetongue 19 is articulated around a living hinge opposed to the retaininglip 18, thetongue 19 acts as a disengaging feature to disengage thelid latch 17 from thelatch retaining lip 18. When closed, thespring 13 is under load, thelid latch 17 is engaged with the retaininglip 18, the movement of thelid latch 17 will push thetongue 19 down which will stop against thetongue stop 23. Thetongue 19 will move down enough so that it creates enough clearance for thelid latch 17 to engage correctly with the retaininglip 18. Thetongue 19 is stopped by thetongue stop 23, these prevent thetongue 19 from rotating any further and being damaged. - Now referring to
FIG. 5 , as thelid 10 is pushed down, it will deform and thelid 10 will be able to slide down the tongue's slide surface, passed that, the latch will engage with the tongue's retaininglip 22. The tongue's retaininglip 22 is made such a way that it's enough to engage and as thelid 10 move back up (in this embodiment of the present invention, the engagement is 0.2 mm, from empirical data, and it has been verified through experimentation and testing that the spring force is enough to overcome such a small engagement). InFIG. 6 , the lid's latch pulling thetongue 19 up with the tongue's slide surface engaging with the cover's retaininglip 18 area is illustrated. -
FIG. 7 illustrates where the lid's latch engagement with thetongue 19 will break as it is not engaged enough to permanently catch on this latch, the force of thespring 13 will overcome the engagement and release thelid 10. e is the main clip engagement, typically 0.7 mm. Element e′ is the tongue retaining engagement, typically 0.2 mm. Element d is the extra stroke necessary for the latch to engage with the retaining clip, typically 0.7. The clearance between thelid 10 and thecover 11 is 1+d, in our simulation, we found out that if thelid 10 is too closed to thecover 11, both will deform at the same time when pushing down thelid 10, thus, the latch will never be able to engage with thetongue retaining feature 15. Thetongue 19 length l needs to be long enough to allow for a close to vertical motion of the tongue retaining engagement. In the current design, a length of 6.5 mm is used. Theta is the angle between thetongue 19 and the main fastening feature. In the close position, thetongue 19 is angled in a way that the lower face of the latch is in contact with the sliding face of thetongue 19 and in the same time, the latch is engaged properly with the main clip, the tongue stop 23 are angled accordingly in order to maintain these requirements. - In the current example theta=10 degrees and the calculated horizontal displacement of the retaining
lip 18 is solved by: displacement=1-1*cos (theta)=6.5-6.5*cos(10) which is closed to 0.10 mm, the current design minimizes the length l, and angle theta, while maintaining a vertical displacement (stroke) d at around 0.8 which is what a user is expected to deform thelid 10 in order to activate the opening of thelid 10. Furthermore, on thelid 10 side, it is expected for the inventors to be able to design alid 10 so that the force applied on thelid 10 to achieve a 0.8 displacement is around 10 N. -
FIGS. 8-9 illustrate simulation results confirming the inventors design, where that the force applied on thelid 10 to achieve a 0.8 displacement is around 10 N. In the simulation for which the results andFIGS. 8-9 were generated, a 10 N force is applied in the general middle area of thelid 10, this leads to that area to deform 5 mm down as shown inFIG. 8 .FIG. 9 clearly illustrates that the latch area deforms by around −1.5 mm whereas the main retaininglip 18 deforms by −0.5 mm which leads to an overall deformation of 1 mm, more than the stroke required to activate the opening. - The present invention will be made out of plastic in an injection molding process.
- Thus, it is appreciated that the optimum dimensional relationships for the parts of the invention, to include variation in size, materials, shape, form, function, and manner of operation, assembly and use, are deemed readily apparent and obvious to one of ordinary skill in the art, and all equivalent relationships to those illustrated in the drawings and described in the above description are intended to be encompassed by the present invention.
- Furthermore, other areas of art may benefit from this method and adjustments to the design are anticipated. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
