Description

VERTICAL SPILL, ENHANCED, NESTED IN INVERTED POSITION ON THE TAPO OF A LATA DESCRIPTIVE MEMORY This invention relates to an enhanced pour spout, in the inverted position, driving arm of a metal hand lever riveted to break the precut protective cap of a metal can containing a liquid. There are numerous metal cans on the market with a metal cover fastened, welded or flanged on the can, designed to contain potable liquids (or non-potable) that can be used for pouring. For some years these aluminum or steel cans have been the object of numerous technological developments, the main ones being applied particularly in the manufacture of cans of carbonated (or non-carbonated) beverages, more commonly called cans, manufactured in the world in quantities of several hundreds of millions a day; These cans are cylindrical, especially due to the fact that the airtight fixing of the covers can be carried out more reliably on circular sections. In the specification of the patent, metallic cans (or cans for beverages) will be taken as a base for the application, which have highly improved covers in the technical aspect.

In general, those concave bottom boats are meant to be stacked vertically. The body of the can is made apart from the cover, which will be flanged by automation at + speed after being filled directly into the beverage canners, called fillers or canners. Indeed, the most advanced technology is directed to be covers that have to be flanged. These, seen from above, have a cylindrical edge, the inner base of which has a circular channel; from the center of the cover emerges the body of a hollow cylindrical pseudo-race, which is formed by breaking the center of the inner face of the cover and / or, therefore, closed at the end hermetically. A small metallic flat lever, called an ear, of elongated shape and having a hole in the center, the diameter of which slightly exceeds the diameter of the aforementioned pseudo-drainer, slides through said hole around the cylindrical body of the pseudo-cramp, In order to be placed extended against the cover before the riveting operation by means of the vertical flattening of the body of the pseudo-rivet pull the lever rotatably captive to the cover. The cover contains a protective layer often often of rounded shape, formed of a perimetric line of detachment along which the mental of the cover is pre-cut.

The ear, of complex manufacture, generally has a nose of trapezoid shape, the edge of which is sewed in such a way that it has good resistance to bends when using the lever for the detachment of the protective layer. In general, according to the manufacturing method of the ear, grooves are provided in the edge of the ear preform, at the end of the nose sewn in a seam, in order to relax the compressive stresses that have appeared when putting together the seam-shaped edge. In the present invention, only the lever and its position in relation to the cover will be claimed as a novelty and will be considered as a common denominator for all beverage can covers, first, having a perimetrically removable protective layer, placed symmetrically in relation to a diametral line of the cover and after that they all have a hollow central pseudo-broach closed at the end and achieved by stamping the inside face of the cover. The invention is therefore intended to offer, in its configuration in relation to the cover of the boat, an enhanced pouring spout, driving arm of a metal manual lever, the resistant arm of which is the hammer, which resembles all the known ear noses, the lever itself being riveted (integrated spout and hammer spout) in the proper direction on the cover as well as all known ears by means of the pseudo-reel of the known art, using the hammer of the lever to break the protective layer with the pre-cut perimeter, also according to known pre-cutting methods. The invention is especially oriented to offer a possibility of a pouring spout, integral part of the lever, because, as can be clearly deduced by the existing methods, while making it possible to open the cans for liquids with metallic can type providing the protective layer of the cover, they do not make it possible to consume drinks directly from the can without the risk of cutting the lips by drinking through the hole in the cover pulled out along its perimeter and drinking directly through the hole originates the spilling of the drink to through the circular channel on both sides of the mouth, making impossible the hermetic application of the lips around the hole due to the concavity of that channel. In addition, when drinking the drink directly from the can, the consumer swallows all the dirt located around the hole and in the sector of the channel located in the hole and the edge of the cover; Even if the contents of the canister are poured into a beaker, the liquid flow carries dirt to the beaker in the same way. The real concerns of boat manufacturers (boat producers) have totally neglected the safety and comfort of consumers. They are busy manufacturing bodies and boat covers that are ever lighter and faster and faster to produce in order to limit metal, manufacturing and transportation costs. The present can covers are provided with a lever for riveting to open for the sole purpose of being able to stack as many covers in a given space as possible and that the determination for maximum stacking limits the ear to its function as a single-layer hammer protective, on the perimeter of which is precut on the cover; this results in a cut hole and an inadequate wet and dirty cover when drunk directly from the can, which is the case with the greatest number of consumers, no matter what the drink is. The following patents may be cited in the technological rationale of this invention: FR-fl-2, 233.239 (CONTINENTRL CRN COMPRNY), US-fl-3, 980, 214 (DRHLQUIST), UO-fl-86.01488 (SCRVO), US- fl-4, 073, 403 (ORflNGE), US-fl-, 000, 838 (BOGERT), US-FL-5,000,337 (IM), US-R-, 561, 557 (PflRK), and US-R-3,473,705 (riflY). In most of these patents the inventors have tried by different means to introduce a pouring spout on the cover of a metallic cylindrical can containing a liquid; These spouts, which are usually submerged in the boat in the assembly, are put in place at the moment of opening after detaching the cover out by pulling a ring. None of these patents have been worked for drinking boats. Patent No. 93,01907 (THOMflSEN &DRIJVER-VERBLIFR) of November 1993, issued by PCT No. NI 94/00265 and published on May 11, 1995, is also part of the technological basis of the invention. It proposes a metal cover of 3 pieces for tin provided with an incunable tongue. This language, called the pouring tongue in the patent, is provided for very thick liquids (for example, condensed milk) or for powders. It actually includes an invertible flat component after the perforation of the protective cap and which contains very low edges on the sides. The inventor, as expressed in his specification, adheres as closely as possible to the concept of a normal flat lever (PPN) riveted on a cover, which retains its flat shape, with the sole purpose of being able to include his tongue in those present production batches. The device of the invention is in no case suitable for common beverages, for which it does not claim to use them (the specification clearly states to the same principle that the incunable tongue (THOMRSSEN to DRIJVER-VERBLIFR) is oriented "to liquids such as condensed milk and possibly powders ") proposing the inventor a respective range of applications, but provided that the user is skillful in distributing them; therefore, the technical requirement of very low edges on both sides of the tongue contributes to the spillage of the content beyond those edges, which are ineffective barriers, particularly in case of flow assertion for any reason. A fundamental difference between the specific language of the THOMRSSEN & DRIDVER-VERBLIFR the pouring spout of the invention is that this, as described later, is a genuine pouring spout, that is, a pouring spout enhanced with high walls, making it possible to either pour or drink directly from the can common liquids ( mineral water and other carbonated or non-carbonated drinks) and also pour thicker liquids, such as condensed oils and milk, as well as powders. The invention is presented in the figures of sheets 1 and 2 showing sheet 3 two original versions of the invention, between and the possible number in terms of the geometric configuration of the present spout. Figure 1 shows (in perspective, as all the following figures of all the sheets are presented) the general concept of the pouring spout 1 in inverted position. In this figure the 5 represents the hole through which it enters, in order to be flanged, the hollow pseudo-recess stamped on the metal of the cover visible in 8 in figure 3; that hole 5 is perforated on the riveter projection 3 of the lever; he represents the hammer with the reinforced nose 10 in active position; the L represents the lip of the pouring spout seen from below, since the pouring spout is in inverted position; 9 represents the edge of the lip L; 12 represents the lower open fastener ring of the pouring spout intended, after the radial rotation at 180 ° of the pouring spout of the cover R, to be housed in the hole of the protective weft 6 of the cover of Figure 3; 13 represents the fastening flange of semicircular section, arranged in additional thickness along the outer lateral part of the open ring 12, that flange of the perimetric clamping system of manual propensity of the ring 12 forming in the hole 6 along the precutting line 7 of the protective layer in figure 3, after bevelled centering of the front edge of the flange 13 at the periphery of the hole of the protective cap 6; at 11 represents a tolerance strip (excess metal), integral part of the riveter projection 3, located between the passive edge of the hammer 2 (opposite side to the nose to open) the riveter hole 5 of said projection. Figure 2 shows the spout (1) in useful position. In this position it is considered that the ring (12) is fastened in the hole of the protective layer (6) in Figure 3; the punch (8) of Figure 3 is shown to be flattened with the (4) in Figure 2 in order to hold the lever (in its initial placement in Figure 1); the lip L represents the upper face in active position and the hammer (2) is passed under the cover in the pseudorrnache in a practically horizontal position; the excess metal (11) extends outwardly enough for the reversal movement of the pouring spout by radial rotation at 180 ° C from the cover, together with a horizontal sliding axis in the direction of the riveted projection (3) towards the hammer (2), to be able to have taken place between breaking the protective cap (6) and holding the ring (12). Figure 2 and Figure 1 together show that the integration of the pouring spout with this reinforced edge (9) and open ring (12), coupled with its fastening flange (13) with the hammer (2), is firmer according to the edge (9) and the ring (12) laterally and symmetrically tightens the side edges of the hammer to form it with a one-piece assembly. In case it is chosen because the pouring spout of the invention will be riveted lying on the plane of the cover, it would be advisable that the plane of the hammer (2) in figure 2 and the plane of the outer edge (9) of the pouring spout were theoretically on the same plane; in that case, the volume of the pouring spout in inverted position on the assembly and riveting extended on the cover would be partially outside the cover, without undermining the vertical stacking of the cans, since the stacking uses the space remaining between the edge (14) in Figure 3 of the cover fl and the point of the flange (13) further away from the hammer. Figure 3 shows in top perspective the cover fl (flanged on the can B) with, as already mentioned, the edge (14), the protective layer (6), its perimeter precut (7) and the body of the hollow pseudorrnache (8) The upper part of the cover has a plane for cutting (15) intended to receive the pouring spout (1) in an inverted position released along the inverted upper plane of its outer edge (9). It can be seen in figure 3 that yes. the plane for cutting (15) is changed down from the base plane of the hammer 2, the hammer then necessarily having to rub the surface of the protective cap (6) and theoretically in the same plane as that of the open ring (12), the The lever of the invention is configured in angular formation between its driving arm and its resistant arm, which was not previously the case with the pouring spout was placed level on the flat cover (without breaking) and the hammer was then in the plane of the outer edge (9) of the pouring spout. The area for breaking (15) in FIGS. 3 and 4 makes it possible to limit the height of the pouring spout (1) after its riveting in the inverted position on the cover B of the can B and to place the lever angularly between its drive arm (pouring spout) and its strong arm (the hammer), in order to minimize the effort to break the protective cap, to the great improvement of the torque in relation to the straight lever. Figure 4 shows the pouring spout (1) in inverted position, a driving arm of the metal manual lever, the resistant arm of which is the hammer (2), riveted in the center of the cover fl, supporting the spigot spout in inverted position on the plane for cor + ar (15) and rubbing the base of the hammer the casque + e shield (6) still in place. The high point (17) of the spout see + edora (1) in inverted position is the upper part of the clamp-open ring (12). That point must be optimally at a height h of the plane of the area to be cut (15), on the other hand, that on the other hand, the spout (1) has sufficient useful height after cutting to allow real ease of use of the spigot and, on the other hand, that the height h brings the point (17) optimally to the plane of the edge (14) of the cover fl, so that the spout does not go beyond the plane of the edge of the cover, which would be disadvantageous for the usual packing of the cans in cardboard packages. It is evident that the useful level of the plane for coring (15) in relation to the plane of the cover fl must satisfy a requirement of technical feasibility with respect to the thickness and the mechanical characteristics of the metal sheets used for the manufacture of the cover . Figure 5 clearly shows, in vertical intermediate position the spout (1), after rornper the protective cap (6), as the tolerance strip (11) makes possible the radial rotation on a sliding axis in relation to the cover fl of the lever assembly enter the possible angular sector of 180 ° C until the cut of the spigot. To facilitate the extension of the directional tolerance strip, after the radial rotation of the lever on a sliding axis at the time of breaking the protective cap, it is desirable for that tolerance to remain between two bending starts perpendicular to the tolerance strip, say, parallel to each other carrying passive of the hammer, that the other passive, which leads the riveting tongue, could turn at the same time from one of the beginnings of bending, having the other that is located slightly ahead of the riveter hole of the tongue that comes from the hammer. Figure 6 shows the pouring spout (1) cut in active position. Again, for the total ease of use, it is advisable that the pouring spout (1) be in a totally fixed position and be integrated with the cover fl of the B can. It would be enough just to cut the spit in the the hole of the protective cap (6) by the flange (13) of the ring (12). However, in use, it would be observed that the elasticity of the cover metal fl would have the effect of leaving the viewing spout (1) floating slightly after cutting. To obtain a real stable position of the pouring spout during use, it is necessary that the lower part of the lip L be supported with slight pressure on the edge (14) of the cover after the cutting of the spout has been completed (1 ) in the protective cap hole (6). It is therefore a matter of using the metal elastic properties of the cover fl and secondarily the metal of the lip L so that the pouring spout (1) is fully subjected to stress after cutting between the outer face of the cover + and its edge . Indeed, after cutting, the cutting flange (13) in the upper area of its section, that is, the area opposite its beveled area, rests on the inner edge of the hole released from the protective cap, thanks to the efforts + combined combinations applied, on the other hand, by the elastic flat face of the cover fl on the flange (13) and, on the other hand, by the edge of the cover that remains freely adjacent to the lower face of the lip L of the spigot pouring (1), which results, in addition, in making possible along the perimeter (7) of the hole of the protective cap-a sufficient metal-to-metal airtightness during the shedding to avoid the discharge of the liquid between the pouring spout (1). ) and the fl cover previously subjected to effort; This pre-stress subjection has a positive result, finally, the fact that the pouring spout (1) rests on the edge (14) of the cover makes it absolutely impossible to pinch the lower lip of the mouth between the spout and the spout. edge the cover. It should be noted that the pouring spout 1 is in a configuration to project slightly beyond the edge of the cover +, always in favor of the greater comfort of the user. Figures 7 and 8 show a variant of the pouring spout that corresponds to the broadest features of the most useful serviceable structure. Figures 9 and 10 represent another variant; in which the shape of the pouring spout is designed so that the pouring spout leans against the portion of the channel it covers. The pouring spout of the invention is handled as follows: when the protective cap 6 has not yet been broken, one simply passes a finger, preferably the index finger, to the hole of the open ring 12, so that the last phalanx of the finger can lean on the lip L of the pouring spout in inverted position, in order to apply there the light force necessary for the action of the hammer 2 on the protective cap 6. It is necessary to indicate here that the community to use-a phalanx and not the tip of the finger and the nail, with the present boats and in the Pawn of Thomassen, in order to activate the lever and its nose to open the protective cap. Women, in particular, who want to protect their nails, fear using their present ears. The pouring spouts of the invention have to be solid and can be manufactured by any known method, including the use of molded plastic on the riveted tongue 3 and, in particular, the manufacturing methods of all the metal ears of the can, in combinations of materials capable of originating the best possible recirculation conditions. The covers equipped with the spouts of the invention will be stackable in a single position and in a slightly smaller number in the same space as the normal lever covers. The riveting of the ear in the center on the current covers was chosen for the covers of the cans for drinks by the small size of those covers; the spouts according to the invention can be mounted on covers of greater diameter; In this case, the riveting would no longer be in the center of the roof. The spouts according to the invention can also be manufactured with riveting in the center of the cover, so that the break, where the spout is nested in an inverted position, remains outside the circular channel located at the base of the rim. , so that the channel retains its important function in the "seam" of the cover provided with the pouring spout on the body of the boat. For this purpose, increasing the length of the riveting tongue between its riveting hole and the passive side of the hammer to which it leads by a calculable value, which is reduced to the same as increasing the amount of excess metal 11, after the radial rotation of the pouring spout on a sliding axis, after breaking of the cover, a cutting position of the sprayer can be obtained beyond the edge of the cover; For this purpose, it is also necessary that the hole with the lid is as close as possible to the channel and so that the pseudo-rectilinear portion of its perimeter is as distant as possible from the point of riveting. It should be noted here that a rectilinear segment of the perimeter of the protective cap below the hammer perpendicular to a diameter of the cover facilitates the placement of the pouring spout. It should be noted, finally, that the invention, at the beginning of the breaking zone 15 of the cover, offers the only possible genetic configuration of integration of a pouring spout with a lever to break, without that spout passing the upper plane of the can and that allows the vertical stacking of the cans.
