  I) Indication of the technical field of the invention.

Screw caps.

  For many hands the receptacles with screw caps are very difficult to open.

  The invention which is the subject of this patent describes a simple technical solution to solve this problem.

  The traffic jams have never stopped evolving. This invention is about going even further and thinking a little about all those who lack strength in their hands. It is therefore not surprising that it is a Doctor who deposits this invention. The average age does not stop increasing, there are more and more 10 elderly people and especially elderly, sick, weakened women and it is still very often the hands of women of all ages who are busy to unclog containers for: cooking, baby's meal, baby's medicine, housekeeping, etc. In this work, it is first of all to take nothing away from the properties of current screw caps, to keep intact the work already done in this area, efficiency, safety, cost price, etc. and then to provide a better one in order to decrease by three or even by twelve the force necessary to overcome the resistance to the opening of the current screw caps whatever they may be.

  11) Indication of the state of the prior art highlighting the technical problem. 20 State of the art: As far as current screw caps are concerned (Plate 1/8. Fig 1 and 2), their evolution has mainly focused on safety in the case of dangerous products or certain medicines in the face of small hands which touch everything. A very ingenious click system is found in the center of many container lids and thus makes it possible, in a tactile and auditory manner, to know if by chance the jar has not been badly closed in the factory, or if a hand has already opened. the pot. There is also sometimes a strip of vertical sticky paper that goes from the lid to the jar and which of course is torn at the opening. System with click and strip are sometimes associated.

  A word from the inside of the metal covers. They are coated over their entire surface with a thin plasticized layer with a thickness of malleable plastic at the circumference which allows sealing. Some covers have a larger plastic coating over their entire inner surface.

  This is to talk about the presence of plastic in current covers. We will come back to this problem later, in terms of technical means.

  Regarding the subject at hand, that is to say how to adapt the cap to the human hand, except for a few vertically grooved caps to allow the fingers to slip less, or some small reliefs around the edge traffic jams, it is clear that the subject has never concerned anyone. It has been established once and for all that everyone has the strength to open a large jar of jam for example and that failing this is not a major problem.

  Let these people get help or arrange as they please with whatever they want! They only have to tap with a knife all around the cap and they will end up 10 succeeding after a few minutes in opening this jar! That these people mostly manage not to buy these products when they can, which represents a big shortfall for the manufacturers, has never challenged them, or maybe if, but they had to do with the caps that the market offers. It's up to us to present them with something better. bisons a word of the capsules because for some bottles it is also possible to unscrew them by hand, which is very practical, but still you have to have the strength of youth and not be afraid of hurting your fingers, this which explains why this means is, in fact, not very widespread. The bottle opener was therefore invented. The idea of using a lever to open a bottle was therefore born but it was not fully exploited and we can understand why. Indeed, the bottle openers use the roof of the capsule as a fulcrum. Yes, but when it is not a capsule but our jar of 20 jam taken as an example, where to find a point of support. Useless to search for a long time, there is none at first sight and even by searching well (and yet ... by searching even better ...

  but we'll see that later), and even if it's a capsule, you still need a bottle opener on hand. The manufacturers therefore rushed to cans or metal cans or brilliant inventors were able to find the principle of the lever and include it on the 25 covers. So a child's finger does as well as big arms! Hence the success of this type of openness.

  The technical problem: The technical problem of screw cap containers is that they are not suitable for human hands. Let us always take for example a jar of glass jam covered with a metal stopper (plate 1/8. Fig 1 and 2). The cover which awaits the hand of man, is less than a centimeter high, it is very round, it sometimes has timid reliefs, it is very smooth.

  It is therefore very difficult to grasp it with your fingertips. The fingers have force, even for Olympic weightlifters, only in gripping, that is to say in bending, outside the opening movement requires bending and rotation of the fingers. Who says rotation, says lateral force of the fingers. All the treatises on physiology of the hand show that the muscles allowing the laterality of the fingers are ridiculously insignificant. The current technique does not take into account these physiological imperatives, hence the difficulties in performing a gesture that is not physiological, that is to say that does not take into account our natural possibilities.

  | Statement of the invention. | Preamble: We have just seen clearly that the current screw caps are not suitable for human hands.

  Finally, it should therefore be remedied by inventing a new type of screw cap taking into account the physiology of the human hand. Since he can't do it with his fingers, he has to do it differently. Man has long known how to use tools to compensate for his poor physical performance. Still, it must be given the means.

  * With what tools? The simplest, the most numerous, those around us: the tip of a knife, the handle of a fork or a tablespoon or coffee spoon. These familiar objects are found in all kitchens and on all tables in numerous copies. They will serve as levers.

  ** With what means? This is the subject of the invention, the description of which follows. I propose to adapt the principle of the lever to all screw caps whatever they are and including the caps of the threaded bottles in order to allow even a child to tackle them with as much success as a fort of halls, but there without bottle opener or other elaborate instruments. The levers are all around us in abundance, so there is no need to integrate them into the lids as in the case of cans. To be able to use these levers, it is therefore necessary to shape a housing, that is to say a cavity, intended to receive them.

  The invention therefore relates to a new type of screw cap comprising a lever housing.

  Technical means to be used to achieve the result sought by the invention.

  They are insignificant. It's DIY for children.

  * For the plastic plug, only a little more plastic is needed to increase the thickness of the base roof by a few millimeters in order to accommodate the housing. It will therefore be necessary to modify the mold at the level of the cap roof.

  ** For the metal cover, you must (plate 2/8. Fig 3, 4 and 5): 1 / a plastic plate (or ad hoc wood, or compressed cardboard, treated then covered with a plastic film) a few millimeters high, 2 / a chisel to cut a circular surface equal to the internal surface of the roof of the cover and cut off the housing, 3 / a second cover to the dimensions of the 10 base cover but without click system and without reliefs for adapting to the container thread, 4 / a metal scissor to allow three actions on this second cover: f cutting out a side slit, f cutting out if necessary a hole symmetrical to the click system at the level roof, reduction of the height of the vertical lateral edge to the thickness of the already cut plastic surface, increased by the thickness of the jail, 5 / a little very powerful glue. These three actions will be in manufacturing by stamping, which will round the window edges and the lower periphery of this second cover so as not to injure. If it has been decided to join the two covers together by crimping or welding, an additional one or two millimeters should be provided at the height of the second cover (plate 5/8. Fig 14, 15 and 16).

  *** Still for the metal cover, it is possible to offer a completely different means of production using a metal blade. It suffices to have a metal blade of the order of 1 mm thick and of the order of 4 mm wide and to shape it around the edges of the housing (board 3/8. Fig 6, 7 and 8) .

  By spring effect, this device engages on the cylindrical part 4mm in height of the upper cover on its internal surface. It then suffices to spray the same plastic film to obtain the same chemical properties as the lower plugs. In this case the amount of plastic added to the current configuration will be a few micrograms.

  Description itself: of the new two-level screw cap.

  It is a plug: 1 / with screw and lever housing. (Definition of Petit Larousse. Housing: place or cavity where a moving part of a mechanism is placed.) 20 / on two superimposed levels and joined together in a single set.

  It is a stopper of which: 10) The lower level with screws, is nothing new, except to be secured to the upper level (plate 1/8. Fig 1 and 2).

  2) The new element is the upper level secured to the lower level and comprising a lever housing (plate 5/8. Fig 14 to 16).

  3) The upper level does not interfere with the operation of the click system of the lower level (board 3/8. Fig 6 to 8) (board 4/8. Fig 9 to 13) (board 6/8. Fig 17) .

  40) The lever housing is suitable for levers such as: knife blades, fork handles, tablespoons, or only teaspoons.

  50) The housing is opened to the outside by a lateral slot suitable for the levers of which he and she are intended and already mentioned (plates 5/8 and 6/8).

  6) The housing is opened to the outside by an upper circular opening, the size of the click system that it overhangs, this when this system exists (planks 5/8 and 6/8).

  To make and dress a lever housing, at each screw cap whatever it is, in a second upper level, in order to allow use as levers; knives, forks, tablespoons or, possibly and only, coffee, this in order to facilitate the opening of the containers, the technical means are, as we have just seen, very simple whether it is as well as '' a small plastic cap of the mineral water type, a threaded bottle cap (plate 7/8), a metal cap of a bottle of antibiotic for 25 children (same plate 7/8), a jam jar cover (plate 5/8) with the click system to keep or honey jar without click system. This housing integrated directly into the base plug, will thus constitute a sort of new plug, which we will say with screws and lever housing, smarter than the simple screw plug and whose contribution of a small second level almost does not appear. To achieve this housing above the base plug 30, the following technical characteristics must be taken into account and the precise measurements will follow. In general and for information we have taken 21mm in width and 4mm in height for the side slit.

  1 / For all plastic caps: in this case The thickness of the cap roof will be increased by a few millimeters to include the lever housing. Base plug, housing and housing lining are molded in the same mass of plastic.

  2 / For all metal stoppers: in this case you must treat: 1] of the housing and 20] of its covering.

  10] With regard to housing: its floor is already made up of the roof of the base plug with or without a click system (plate 1/8), its own roof will be treated with its covering, the three walls of a few millimeters in height (plate 2/8. Fig 4 and 5) (plate 3/8). Take a plastic plate 10 of this thickness, choose a deformable plastic, cut a circular surface with a diameter slightly smaller than that of the cover, and finally cut in this surface the housing as will be described later.

  20] As regards its covering (plate 2/8. Fig 3): it is a cover of the same kind as the base cover (plate 1/8) which is superimposed on the base cover. Its characteristics are as follows: (1 *) it serves as a roof for housing, (2 *) it is pierced or not on its roof with a circular orifice equal in diameter to the click system and (3 *) this so as to overhang it perfectly, (4 *) its height is equal to the thickness of the housing increased by the thickness of the metal sheet which constitutes it, (5 *) the plastic surface in which the housing has been cut is glued to its underside (in its concavity), (6 *) the entrance to the housing is produced by cutting out the necessary rectangle on the lateral edge of this second cover, (7 *) the edges of this entrance as well as that of the orifice of the roof are blunted so as not to injure, (8 *) this assembly: second cover plus housing is secured to the roof of the base plug, this in several ways, * either by a second bonding, but this time of the underside of the plastic plate to the roof of the base cover, ** either p ar soldering or crimping or other technical means, by its circumference less than the upper circumference of the base plug. in all cases the circumference of the junction of the two stages is blunt or treated in any way so as not to injure.

  At this stage of the description, certain points should be clarified; namely: the appearance and dimensions of the housing for each plug.

  We had said: "The upper level, comprising a lever housing, does not hamper the functioning of the possible click system of the lower level". Like a garage, the housing 5 is formed by an entrance, two side walls, a back wall, a floor and a roof. It is sufficient that the side walls of the housing and the back wall are all tangent to the circle of the click system of the floor so as not to hinder it (board 3/8. Fig 8) and (board 4/8. Fig 9 to 11 ). Thus, the two rectilinear side walls, go from the entrance to the bottom of the housing, widening just enough not to encroach on the click system. As for the back wall, it will be an arc tangent to the click system, the center of which is in the middle of the entrance.

  We also said: "The lever housing is suitable for levers such as: knife blades, fork handles, tablespoons, or only teaspoons", "The housing is opened to the outside by a lateral slot suitable for the levers of which he and she are intended and already mentioned ".

  So it is the dimensions of the entry (21mm by 4mm for information) and the radius (r) of the click system which determine the upper view (plate 8/8. Fig 20) and the profile view of the housing ( plate 6/8). We have two variables there, but they pose no difficulty.

  When the lid lends itself to it, and this is by far the most frequent case, we will take the width of the handle of a common tablespoon plus two millimeters for the width of the entry (hence the 21mm ) and we will use the same type of calculation for the height (hence the 4mm). Otherwise, we will use, according to the same calculation, the values of the handle of a teaspoon. The value of the radius of the click system (r) which varies from one cover to another does not matter, so the walls will be more or less flared, which has no functional impact (plate 4/8. Fig 9 to 11). There, 25 in this talk, by inference, are all the measures.

  A word for the simpler case where there is no click system, ie on the metal lids of certain jars of honey, or for all plastic caps and capsules. In this case the housing is simply a parallelepiped (board 3/8. Fig 7), (board 4/8. Fig 12 and 13) and (board 7/8. Fig 18). It is the entrance that determines its height and width. As for the depth, it is determined by common sense, if the stopper is small, it will be the diameter of the stopper (2R) and if it has the dimensions found on the snap-on lids, it will be the radius (R) of the cover plus possibly a few millimeters of common sense.

  | Understanding the technical solution which is brought to the technical problem posed: | The object of our purpose is not to create a new cap which would be more airtight, more secure or of a lower cost, but to add, in several ways, to all existing caps a small supplement, to improve them. , to make them adapt to the hand of man 5 and not the reverse as is currently the case, to make them smarter in a way, in order to bring better to reduce by three or even by twelve the force necessary to overcome the resistance to the opening of current screw caps whatever they may be.

  It is therefore necessary, after speaking of the physiology of the hand to bring out the technical problem of screw caps, to now study the opening movement of the cover in terms of physics (plate 8/8) in order to to allow the understanding of the technical solution brought to the technical problem posed. This movement, in fact puts itself in equation, it is "the movement of the couple", fortunately very simple: P xd = px D. (P) being the force of resistance to the opening, (p) being the against force it will be necessary to oppose more a 15 iota to manage to mobilize the cover. But who says "movement of the couple", says point of support l Outside we said that there was none at first sight, we also said that by looking better ... In fact this point of support exists, but it cannot be seen because it is not material at first sight (but in fact it is material, but we do not seek it where it is needed ...).

  Physics tells us that it is at the center (O) of the circle represented by the cover, and that it is carried by the virtual axis which is perpendicular to the cover at its center. This virtual axis is held by the left hand. How is it virtual? Physics tells us that the vertical wall of the container acts as a virtual axis. Physics also tells us that it is in fact the left hand which represents by its force the force of this fulcrum but at the center (O) of the cover. We can thus say that (d) is the distance from (O) to (P) and that (D) is the distance from (O) to (p). (d) and 25 (D) are two line segments on the same line. As the cover is made, we are in the case of two children of the same weight on a swing (board 1/8). Thus, (P = p), resistance and counter-resistance are equal and (d = D), resistance and counter-resistance on opening are equidistant from the fulcrum (O) but diametrically opposite. The couple's movement tells us that for (p) to be smaller than (P), (D) must be greater than (d). It is the rule of the very simple lever, but fortunately man has been able to use a lever as a tool to multiply his forces before knowing the equation.

  It is sort of the special swing that is needed when one of the children is very large and the other is very thin and where the fulcrum is shifted to the side of the large (board 8/8. Fig 21). Thus a mouse can swing with a mammoth provided that (d), on the mammoth side and (b), on the mouse side, suit the equation. Hence the famous phrase: "give me a point of support and I will raise the world>". For what concerns us we will be satisfied with the screw cap. It therefore remains to create an original configuration allowing (b) to be much larger than (d), the radius of the cover (d = R) and in this case, by the law of physics Pxd = px b.

if D = 5d for example, p = P / 5.

  This is detailed in the description of the invention above (plate 8/8. Fig 20 and 21).

  Starting point: (plate 1/8. Fig 1 and 2).

  A simple screw cover with click system.

  This is the first level. The elements added: (plate 2/8. Fig 3, 4 and 5) or (plate 3/8).

  The accommodation: (board 2/8. Fig 4 and 5) or (board 3/8).

  Its covering: (plate 2/8. Fig 3 with or without the upper opening).

  It is the 2nd level In the end: (board 5/8) and (board 6/8) or (board 7/8). 20 The two levels are united.

  It is the new type of screw cap and lever housing in two levels.

  Just one example (for short): (Plate 8/8) P = resistance to opening. p = counter resistance to opening.

  d = R = radius of the cover. L = length of the knife.

  r = radius of the click system. D = (L - r).

  Pxd = P x R. p x b = p x (L - r) Pxd = p x (L-r) If bD = (L-r) = 5d p = P / 5. CQFb.

  In this case, we have divided the force to be applied for the opening by 5.

  Let us not forget that in addition this force (p) does not apply with the fingertips (flexion and rotation, see physiology of the hand) but with all the force of the right upper limb in a right-handed person.

  As an anecdote, let us also say that left-handers will be favored because one unscrews in a counterclockwise direction, and that the muscles of adduction are clearly more powerful than the muscles of abduction. It is enough to make a pump on the palm of the hands then on the back of the hands to be convinced ...! i1
