1) Technical field of Invention
This Jar Opener is an original tool, used to open jars or bottles and it is based on the fact that inside any jar, there is a vacuum effect, created when the jar is sealed and the lid is held tight in place by a friction force.
To break the tightness between the lid of the jar, the Jar Opener QT1 tool sharp Impact pin (9) creates an impact on the lid, removes the vacuum and cancels out its friction force and the lid should be turned open easily.
The novelty comes from the fact that this simple tool described above is more versatile and secure, more powerful and giving less stress on the wrist, than most of the existing solutions on the market for purposely identical tools.
2) Background of the field of Invention
The various openers are used since the invention of the jars having their functionality, reliability and usefulness over a large spectrum of ideas and variations.
However, when using these tools for a certain period of time, stress and damage of the wrist joint occurs resulting in fatigue of the hand.
It is claimed as an original idea to help with the ergonomics and to win over the other existing tools, when the strain becomes an issue.
Evidently the low manufacturing cost plays an important role in achieving the goal and it has an advantage over majority of competitors in the field.
With only one push of a button, almost any type of lid for jars and bottles is decompressed and freely removed.
The preferred embodiment is thermoplastic construction made by injection-molding process with an addition of the three springs and a Locking pin Fig. 1 and 3.
It is considered by the inventor that the originality of the invention comes from the fact that never before this assembly has been put together in the same manner with a great advantage over the other existing tools.
-The tool QT-1 has to be positioned in the center area, on top of the lid of a jar or bottle.
-By pressing the top of Housing (1) with one’s palm, the Loading slide (8) will be pushing up the Ejector slide (6) that is hooked up around the Locking pin (4) . The spring (7) that is in tension will move down The Slide (8) to the initial lower level. The tension of the Spring B (5) has to be twice the tension of the Spring C (7).
-By pressing the Button (2), the fork of the Ejector slide (6) is released from the Locking pin (4) and because of the tension from The spring (7), will move down all the way together with the Contact impact pin (9)that will impact and dent or pierce the lid, canceling the vacuum effect.
-Without any pressure and friction on the lid, this one can be rotated freely, the jar (bottle) will be open easily.
