Abstract

double opening system for beverage cans the lid of a beverage can has two perforated segments, which break into the respective openings to allow liquid to flow out and air to enter. breaking of these perforated parts is performed by pivoting up a main ring mounted on a rivet of the cover and, after breaking open the perforated part, pushing down a secondary lever with parts of the cutting pressure that cut in the perforated parts to cause the rupture of this. the said secondary lever is mounted on the same rivet, having an end segment that rests against a stop of the ring to prevent a rest condition that the pressure cuts through the pierced parts. in another simpler embodiment, the secondary lever is dispensed with, so that the pressure part is incorporated along the contour of the associated main ring.

Description

DOUBLE OPENING SYSTEM FOR DRINK CANS OBJECT OF THE INVENTION

The present invention, as indicated by the title of this specification, relates to a double opening system for beverage cans to perform the execution of two openings in the corresponding top lid of the beverage container or it can also refer to the object of allowing the exit of the liquid during its consumption and, in turn, the entry of air to prevent the liquid from spilling out in a disorderly manner.

Another object of the present invention is to be able to perform the opening of the orifice for the entry of air with minimal effort by the user, also preventing the accidental opening of that orifice for the entry of air.

BACKGROUND OF THE INVENTION __

The beverage containers or cans generally have an upper lid for closing the mouth, in which the lid has a mold cut that determines a weakening line to obtain, when the time comes, a drink discharge orifice, a rivet for attach a ring that also exists next to this mold cut whose retraction carries with it the opening, when the inclination and compression of said ring are carried out in the mold cut area, producing its rupture and, therefore, the opening of the can is established, allowing the liquid to escape.

Clearly, the opening or orifice made in the aforementioned manner, in addition to being the outlet medium for the liquid, also constitutes the outlet for the air to enter, with which the liquid and air collide and the liquid gushes out in a disorderly manner.

DESCRIPTION OF THE INVENTION

In order to achieve the objectives and avoid the drawbacks mentioned in the preceding paragraphs,

2/10 invention consists of a new double opening system for beverage cans that is centered, in principle, on the fact that the ring used to break the mold cut that establishes the liquid outlet hole is complemented with a lever secondary mounted articulated on the same rivet that assembles the main opening ring, with the special feature that this secondary lever always acts subsequently to the main ring, to effect the rupture of the mold cut or mold cuts that correspond to the air inlet, in which these are separated from the mold cut corresponding to the liquid outlet, with the special feature that the main ring has a wide window to allow the mold cut rupture lever to be placed on it, which will lead to the inlet hole of the air, and the free end of this lever being supported in a damper provided for this purpose in the main ring, to prevent This lever does not act 'until' the break in the mold cut that establishes the liquid outlet through the main ring has been carried out. -.....- ------------------- ’--- -

The secondary lever for tearing the mold cut for the air inlet, which is mounted on the same rivet as the main ring for tearing the mold cut for the liquid to escape, features one or two pointed hammers to pierce the lid, so that only a centered hammer is desirable for the purpose of minimizing the user's efforts, although, if it is not pressed perfectly in the direction perpendicular to the cover, the lever should twist without being able to tear the mold cut, and thus two hammers are arranged in a preferred embodiment, thereby enabling the lever to be more stable in operation with pressure from it to establish the orifice that corresponds to the air inlet, with the possibility that a

3/10 of the hammers can be blinded, so that it can only be used to stabilize the mechanism.

The mold cut or mold cuts that are intended to be drilled or torn by the aforementioned hammer or hammers must be arranged centrally when it comes to a single mold cut, or one on one side and the other from a deep notch that gives stiffness to the area and thus prevents the protrusion of the lid in the opening processes, in the case of two mold cuts.

The hammer or hammers of the mentioned secondary lever have a cutting profile to initiate a perforation of the mold cut, and subsequently push the respective tongue to widen the initial break and increase the width of the hole.

------ Conformè previously mentioned, the main ring by means of which the rupture of the mold cut for the liquid outlet is made has a damper for the free end of the aforementioned secondary lever, so that when the ring it is pulled upwards to make the corresponding opening during its inclination ', “it is dragged on the inclination up to the mentioned lever until a point where it is released due to the fact that both elements (ring and lever) have different radii of rotation, so that when it is tilted upwards from the main ring, it takes the lever with it, and the lever is tilted until the end of said lever is released from the damper established in the main ring for this purpose, whereby one side of the damper prevents accidental perforation of the mold cuts for the air inlet to be made, and, on the other hand, once the ring tilt has been performed and the opening of the liquid outlet has if done, the lever can be pressed down and its hammers can execute the corresponding opening.

4/10

The damper provided in the main ring to prevent the lever hammers from accidentally drilling and / or tearing the mold cuts that establish the air inlet orifice can be designed either by tilting up or down, so that at any if the upward tilt of the main lever drag the lever longitudinally with it to a point where its end is released from the mentioned damper, as a consequence of the different radii of rotation of the ring and the lever.

In a variant of the embodiment, said shock absorber may consist of a bridge elevation of the end of the main ring, so that, in addition to performing the functions of the shock absorber, it allows the introduction of someone's fingertip to facilitate pulling or pushing. up_ q said main ring.

The arrangement and structure of the secondary lever allows you to increase the effort of tearing the cut of the mold that will establish the opening or hole for the entry of air. This increased effort is. achieved by using the concept of leverage, strictly speaking.

In a simpler embodiment, the secondary lever is dispensed, so that in this case the main ring has a lower end portion that falls into an area bounded by the mold cut of the lid, executing its rupture and thereby releasing the opening orifice. air inlet, after having previously released the liquid outlet.

DESCRIPTION OF THE PREFERRED ACHIEVEMENT

As can be seen from the figures mentioned above, the double opening system for beverage cans according to the object of the invention comprises a main ring 1 through which the breaking or cutting of the. mold cut 2, established in the corresponding cover 3

of the container or can of beverage, where the mold cut 2 delimits an tongue 4 that with the slope of the ring main 1, through rivet 5 as your element in Assembly in articulation, loosen that tongue 4 for O inland in in order to establish the exit hole in liquid. At the even rivet 5 for the tilt and assembly of

main ring 1, a secondary lever 6 is mounted with cutting hammers 7, where the lever 6 is located in a window provided for this purpose in the main ring 1, the end of which has a smaller narrow sector 8, which is supported on a damper 9 emerging from the main ring 1, as shown clearly in figures 1, 3 and 4, so that, in the resting position, the main ring 1, as is conventional, remains joined on the surface

Top 7/10 of the lid 3, and the end sector 8 of the lever 6 is supported on the vertical flap of the damper 9, preventing the hammer 7 from falling into the lid 3, and specifically in the mold cuts 10 established in said lid 3, whose rupture or rupture, as will be explained later, carries with it the formation of holes for the entrance of the air, allowing the consumption of the liquid contained inside the can or container at the same time that the air enters through these holes caused by the removal of the tongues of limited by the mold cut 10, and these are distanced from the mold cut 2 which corresponds to the liquid outlet hole, making it impossible for said liquid to exit through those holes of the mold cuts 10 when consumption is carried out.

That is, based on the proposed characteristics and solution, the main ring 1 and specifically its damper 9, blocks the movement of the lever 6 corresponding to the cutting hammers 7, being necessary that the main ring 1 performs the. its upward movement_to execute the break or break of the mold cut 2 that corresponds to the liquid outlet hole, in whose inclination the main ring 1 drags the lever 6 with it, which will also tilt upwards, articulating in the rivet 5, until it releases lever 6 of ring 1, that is, of its damper 9 due to the fact that they have different radii of rotation, so that, once the opening of the liquid outlet has been made, if the main ring 1 is pressed down, the lever 6 is dragged and the hammers 7 fall into the mold cuts 10, causing the tear to break and the corresponding opening of the holes to allow air to enter.

Between the die cuts 10 and in order to give greater consistency to that area of the lid, a deep notch has been provided, as shown in figure 2.

8/10

In figures 5, 6 and 7, a variant of the realization of the damper for the end sector 8 of the lever 6 is shown, so that, in this case, said damper is formed by a tab 9 'projected downwards in an inclined manner , in order to constitute a ramp to the end edge of the end sector 8 which initially holds it and, therefore, the lever 9 'until the release is produced in the upward inclination of the main ring 1 as can be seen in figure 6 , which shows the point of rotation or inclination at which the aforementioned release is precisely produced. In this variant of the embodiment, the secondary lever 6 remains practically horizontally, as can be seen in figure 6, with less risk of being accidentally activated or pressed. In addition, it can be seen that there is a different design from the previous figures, since the main ring 1 has a double lobe shape and a large window, while the secondary lever 6 is extended - oval and also provided with a window.

The secondary lever - to open the holes for the air inlet can be made of aluminum, or even a strip of stamped iron, featuring a 10 ° pre-fold directly above the rivet 5, in which the section for ensuring the folded axis has been reduced, while the hammers 7 of said lever 6 are folded to 90 with respect to the upper face of lever 6.

Finally, it must be said that the damper for the secondary lever 6, instead of being formed by a flap, is determined by a connection elevation 9 established at the end of the main ring 1, allowing the position of the finger end below said elevation connection 9 to facilitate the activation or upward thrust of said main ring 1 in the can opening operation or

9/10 beverage container at the moment.

In figures 9 and 10 a simpler realization is shown, although less advantageous than that shown in the previous figures.

In said embodiment, the main ring 1 'does not contain the secondary lever 6, so that in this case said main ring 1' has a lower end portion in the form of the downwardly directed hammer 7 'which will fall in the area of the bounded cap by cutting the mold 10 ', producing the rupture and corresponding opening of the orifice to allow air to enter.

As in the previously described embodiment, in the case of the simple embodiment (figures 9 to 13), the rupture of the mold cut 10 'is carried out after tilting the main ring 1 ^r upwards to release the outlet orifice, of liquid, which delimits the tear tab 4, so that with tilting the main ring 1 ¹ down again until it reaches its initial position and pressing on the end -sua-, the lower end portion of the hammer 7 'of said main ring -1 ', said .martelo_ falls in the area bounded by the aforementioned mold cut 10', producing its rupture and, therefore, the opening of the air inlet hole.

In figures 14 and 15 there is shown a third more advantageous embodiment in which, starting from the embodiment shown in figures 1 to 8, a secondary lever 6 'is incorporated, which has a central flexing characteristic 12 formed by two downward converging planes de limit a projection in low relief that constitutes the corresponding hammer 7 which faces a mold cutting unit 10 whose rupture determines the air inlet orifice. The secondary lever 6 'also incorporates a characteristic sector of the angular configuration 8', in the

10/10 which will drop the buffer 9 'from the main ring 1.

In turn, the contour delimited by the main ring 1 characterizes a characteristic peripheral thickening with a rounded cross section plus 5 ergonomics, whose continuity is interrupted by a narrow portion 13 that facilitates the initiation of the elevation of the main ring 1.

In figure 16, a characteristic protuberance 14 is shown in the form of a limited spherical cap 10 for the mold cut 10, which corresponds to the air intake inside the can.

However, this protuberance is also applicable to the 10-10 'die cuts of the other two embodiments.
