Description
A GEL DISPENSER AND DISPENSING METHOD
Field of the Invention The present invention relates to the field of gel dispensers. More particularly, the invention relates to a method and apparatus for dispensing gel.
Background of the Invention
The term "gel" refers herein to a substance that can have properties ranging from soft to relatively hard.
Gel, for example, toothpaste, glue, ketchup, is conventionally sold within a package having a hole with a cap which is manually opened or closed. The dispensing may require squeezing or shaking.
However, the dispensing of these packages is not controllable. Another problem of conventional gel dispensers is that the content is not accessible since the hole is narrow, and thus there is a difficulty to dispense the entire content.
All the methods described above have not yet provided satisfactory solutions to the problem of controllable dispensing.
It is an object of the present invention to provide a package providing controllable dispensing therefrom. This package must not require any external tools.
It is an object of the present invention to provide a solution to the above-mentioned and other problems of the prior art.
Other objects and advantages of the invention will become apparent as the description proceeds.

The reference numbers have been used to point out elements in the embodiments described and illustrated herein, in order to facilitate the understanding of the invention. They are meant to be merely illustrative, and not limiting. Also, the foregoing embodiments of the invention have been described and illustrated in conjunction with systems and methods thereof, which are meant to be merely illustrative, and not limiting.
Brief Description of the Drawings
Embodiments and features of the present invention are described herein in conjunction with the following drawings^
Fig. 1 is an exploded view of a dispenser according to one embodiment of the present invention. Fig. 2 is an assembled view of the dispenser of Fig. 1.
Fig. 3 is a cross-sectional view of the dispenser of Fig. 1 at the assembled state. It should be understood that the drawings are not necessarily drawn to scale.
Detailed Description of Preferred Embodiments
The present invention will be understood from the following detailed description of preferred embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail. Fig. 1 is an exploded view of a dispenser according to one embodiment of the present invention.
A dispenser 1 includes cylinder 10 for containing a spread or gel content therewithin, which is filled prior to assembling dispenser 1.
Cylinder 10 is covered at the bottom thereof by an openable mouthpiece 2 made of a resilient material, such as silicone. Cylinder 10 is covered at the top thereof by a stationary cap 8, which may be screwed or cast to cylinder 10.
Fig. 2 is an assembled view of the dispenser of Fig. 1. Cylinder 10 together with mouthpiece 2 and cap 8 form an elongated container enumerated 22. According to one embodiment, elongated container 22 may have other elongated shapes rather than cylindrical.
The term "relatively short distance" refers herein to a distance being less than a tenth of the length of container 22.
At the first step, which is pressing a short button 13 thus along a relatively short distance downwards being direction enumerated 24, a predetermined amount of the
content 12 is released via mouthpiece 2, due to the relatively short distance sliding of piston 6.
At the second step, button 13 automatically rises up, i.e, in a direction 26, allowing repeating further cycles of the first and second steps.
In regard to the definition that the term "relatively short distance" refers to a distance being less than a tenth of the length of container 22, for removing the entire content 12 from container 22, more than ten strokes are required, since each stroke removes less than a tenth of content 12.
Fig. 3 is a cross-sectional view of the dispenser of Fig. 1 at the assembled state.
Dispenser 1 includes a rod 4, the length of which is almost the length of the dispenser. Each press of button 13 shifts rod 4 downwards. The shift is at a relatively small distance, as depicted by the length of button 13 (shown in Fig. 2) and by the distance of the press of button 13.
Thus, at the first step, being the manual step, rod 4 is pressed downwards along direction 24 at a short distance! and at the second step, being the automatic step, rod 4 is pulled upwards along direction 26 at the same short distance.
At the first step that rod 4 lowers, a piston 6 lowers at the same distance, due to firm attachment between piston 6 and rod 4. Piston 6, upon shifting downwards at the short distance, presses the content 12 downwards. Content 12, by the pressure thereon, stretches mouthpiece 2, which opens, to release content 12.
At the second step that rod 4 rises at direction 26, piston 6 remains in the same place, since tooth 16 allows skipping
teeth 14A, 14B, etc. of rod 4 upon motion of rod 4 in direction 26.
Thus, rod 4 moves in relation to piston 6. Piston 6 remains at the same displacement, due to friction between piston 6 and the inner wall 28 of cylinder 10, being for direction 26 stronger than the attachment between piston 6 and rod 4.
Thus, at each cycle, including the first and second steps, rod 4 lowers and rises, but piston 6 only lowers. At every cycle piston 6 slides through container 22.
Various mechanisms for providing this above-mentioned one -directional functionality may be included.
According to the example shown in the figures, the one- directional mechanism includes a one -directional connection of rod 4 to piston 6 via one -directional teeth, and friction between piston 6 and the inner wall 28 of cylinder 10.
Rod 4 includes a plurality of one -directional teeth 14A, 14B, etc. disposed therealong; and piston 6 includes a one- directional openable gripping tooth 16, surrounding rod 4. Both teeth 14A, 14B, etc. of rod 4 and tooth 16 of piston 6 are directed to allow piston 6 to slide along direction 24 in relation to rod 4, and to avoid the other direction 26.
According to another embodiment, one -directional attachment between piston 6 and rod 4, for attaching therebetween only upon manually pressing piston 6, and for sliding therebetween in the other direction may be obtained by one -directional gripping, which may apply changing the angle of one of the elements as a function of the direction thereof, as applied by caulking guns and hot melt adhesive gun. However,
unlike these tools, in which the container and the glue are separated from the sliding mechanism, piston 6 and rod 4 are disposed entirely within container 22.
According to this embodiment the one -directional mechanism includes a one -directional openable gripping lock fixed to piston 6. The lock surrounds rod 4, gripping rod 4 upon motion of rod 4 along direction 24, and for allowing rod 4 to slide along direction 26. The friction between piston 6 and the inner wall 28 of cylinder 10 of container 22 retains the location of piston 6 in relation to container 22 upon the sliding of rod 4.
Referring again to Fig. 1, the pressing on button 13 results in pressure on a springy element 9. Springy element 9 grips a tooth 18 of rod 4 disposed at the top thereof, as depicted in Fig. 3. Thus, at the first step of pressing button 13, springy element 9 bends! and upon releasing the manual press from button 13, springy element 9 releases by pulling top tooth 18 of rod 4, thus pulling rod 4 upwards along direction 26, performing the second step.
Piston 6 is sealed to the inner cylindrical wall 28 of cylinder 10, for avoiding leakage of the content 12 therebetween, and for not allowing piston 6 to rise up, together with rod 4, when pulled by springy element 9.
An additional central seal 5 between rod 4 and piston 16 may be added for avoiding leakage of the content 12 therebetween.
Piston 6 and rod 4 are disposed within container 22, and the strokes by pressing button 13 are performed from outside container 22.
Mouthpiece 2 is disposed within container 22. Mouthpiece 2 opens by pressure of content 12 thereon for allowing release of content 12. The pressure on content 12 is induced by piston 6. Mouthpiece 2 closes for keeping content 12 fresh within container 22 upon cessation of the pressure.
A cover 7 prevents release of button 13 and other elements. A disk 3 holds resilient mouthpiece 2 in its location.
Referring to Fig. 3, a handle 11 may be added for performing the pressing described by button 13.
According to another embodiment, piston 6 may manually be slid within container 22 by manually rotating piston 6 in relation to cylinder 10.
