[001] The present invention refers, under the nature of utility model, to a new constructive arrangement applied to a beverage can, for allowing a quick and easy opening of the latter, by the provision of a vent opening and, optionally, of a pouring opening, in an end wall of the can, usually the upper wall or lid, when a user/consumer manually actuates a first, and if desired, a second actuation tab, allowing said two actuation tabs, jointly with the vent and pouring panels, which form the vent and the pouring openings, respectively, to be easily and quickly detached from the upper end wall of the can, immediately after liberation of each of said openings .

Prior Art

[002] It is well known in the state of the art the use of cans having an end wall provided with a first and with a second tearable panels, in order to form, respectively, a vent opening and a pouring opening, the vent opening being diametrically spaced from the pouring opening, so as to assume an upper position in relation to the latter, when the can is inclined to a horizontal position, in order to allow the air to be continuously admitted into the can through the vent opening, while the beverage is being poured out from the can through the pouring opening. The provision of the vent opening allows the beverage to be released from the can, in a uniform flow and more rapidly.

[003] Patent documents BR 20 2016 000915-0, BR 20 2016

006035-0, and US 2014/0263320 Al illustrate the type of construction mentioned above, according to which the actuation of the user/consumer over a single actuation tab, promotes, initially, the rupture of the first panel (vent panel), with the formation of the vent opening for facilitating the discharge of the beverage through the pouring opening, which is subsequently formed upon rupture of the second panel, by the progressive action of the user/consumer over the single actuation tab.

[004] In said known beverage cans, having two breakable panels, the actuation of the single actuation tab leads to the compulsory formation, not only of the vent opening, by removing the vent panel, but also, and subsequently, of the pouring opening, by pressing the second breakable panel, or pouring panel, to the interior of the can. The pouring panel is bent around a reduced and not weakened extension of its breakable contour, which extension operates as a hinge defined by the metal foil itself of the respective end wall of the can. In this known construction, the pouring panel remains attached to the end wall of the can, projecting to the interior of the latter, remaining in contact with the beverage and transmitting, to the latter, for ingestion of the user/consumer, all the pathogenic microorganisms usually present in the exterior of the end wall or lid of said cans, when the latter are not submitted to a rare efficient cleaning before being opened and, mainly, before being used as a "drinking glass". Besides maintaining the pouring panel attached to the can and projecting to the interior of the latter, this solution with a single tab prevents the user/consumer from promoting only the rupture of the vent panel, in order to form only the vent opening to be used to introduce the straw for sorbing the beverage. [005] On the other hand, the solution of patent PI

0403324-8 provides two actuation tabs, which requires the user/consumer to pull one actuation tab, in order to form the vent opening and allow access to the other actuation tab, to be optionally pulled to form the pouring opening. Although allowing only the formation of the vent opening for introducing a straw to sorb the beverage, said prior solution does not eliminate the inconvenience of maintaining the pouring panel projecting to the interior of the can upon formation of the pouring opening.

[006] Patent documents GB 353,598, US 3,655,091, US

4,042,144, US 4,913.305, and BR 20 2014 032067-4 describe different constructions for providing the opening of a pouring panel in an end wall of a can, by means of a single lever or tab which, when actuated by the user/consumer, promotes, initially, a rupture localized in the weakened line of the breakable contour of the pouring panel, allowing the tab or lever to be then pulled by the user/consumer, completing the rupture of the whole contour of the pouring panel, which is then detached from the can, without the inconvenience of being pressed to the interior of the latter and contacting the stored beverage.

[007] While eliminating the problem of bending the pouring panel to the interior of the can, the constructive solutions mentioned in the previous paragraph do not allow the user/consumer to provide a vent opening for allowing the beverage to be released from the can in a uniform flow and more rapidly.

[008] Patent document US 3,477,608 discloses a constructive solution to provide the formation of a vent opening and, subsequently, the formation of a pouring opening in an end wall of a can, by means of a single lever or tab which, when actuated by the user/consumer, promotes, initially, the complete rupture of a vent panel and a localized rupture in the weakened line of the breakable contour of the pouring panel, allowing the single lever to be then pulled by the user/consumer, completing the rupture of the whole contour of the pouring panel, which is then detached from the can, without the inconvenience of being pressed to the interior of the latter and contacting the stored beverage.

[009] Although eliminating the problem of bending the pouring panel to the interior of the can and of providing both the pouring opening and the vent opening, the construction described in document US 3,447,608 does not allow the user/consumer to promote only one vent opening, if so desired, in order to sorb the beverage by means of a usual straw, without the risks of causing splits which occur upon formation of the pouring opening, which presents a larger dimension. In these solutions, the single tab or lever promotes the compulsory formation of both openings.

Summary of the Invention

[0010] Due to the drawbacks mentioned above and related to the known solutions, it is an object of the present invention to provide a constructive arrangement for the opening of a beverage can, which allows the user/consumer to provide the formation of a vent opening and, subsequently, and if desired, the formation of a pouring opening spaced from the vent opening, both formed by the respective panels of the end wall of the can, which panels form the vent opening and the pouring opening and which are completely detached outwardly from the can.

[0011] The present constructive arrangement is applied to a beverage can of the type which comprises an end wall, in which are defined a vent panel and, spaced from the latter, a pouring panel with a larger contour.

[0012] According to the invention, both panels have the contour thereof totally defined by a rupture line, it being also provided a first actuation tab, having an extracting end portion, externally affixed to the vent panel, and a grip end portion, which is manually and angularly displaced away from the end wall of the can and separated from the latter jointly with the vent panel, and a second actuation tab, which is optionally actuated after the vent panel is removed and presents a punching end portion, externally affixed to the pouring panel and provided with a lower end tooth, to be pressed against a confronting spot region of the rupture line which defines the contour of the pouring panel, and a grip end portion, whose manual angular displacement, away from the end wall of the can, breaks, initially, said spot region of the rupture line and, subsequently, separates the pouring panel from said end wall.

Description of the invention

[0021] As illustrated in the appended drawings and discussed above, the present constructive arrangement is applied to a beverage can L of the type which comprises an end wall 10, usually in the form of an upper lid surrounded by an adjacent edge 21 defined in one of the ends of a usually cylindrical sidewall 20 of the can L. The end wall 10 incorporates a vent panel 11 and a pouring panel 12, which are spaced apart, generally in a diametrically opposite arrangement. It should be noted that the contour of the pouring panel 12 is generally much larger than that of the vent panel 11.

[0022] According to a first aspect of the present invention, the vent panel 11 and the pouring panel 12 have the contours thereof totally defined by respective rupture lines 11a, 12a, which allow said respective panels to be ruptured along the contours thereof, for the formation of a vent opening Al (as illustrated in figures 4, 5 e 6) and, subsequently and optionally, of a pouring opening A2, respectively (as better illustrated in figures 5 and 6) . This type of can may be constructed in different ways well known in the art and which are not part of the present invention.

[0023] The can L further comprises a first actuation tab 30, constructed in a single piece and in any metal alloy adequate to the present use, having an extracting end portion 31, affixed externally to the vent panel 11 by means of a retention element 35, of any known construction and which, for example, may take the form of a rivet 35a, hermetically incorporated to the vent panel 11 of the end wall 10. The first actuation tab 30 further comprises a grip end portion

32, generally of annular shape and to be manually and angularly displaced away from the end wall 10 of the can L, breaking the rupture line 11a of the vent panel 11 and separating the latter from the end wall 10 of the can L, as illustrated in figure 4.

[0024] The extracting end portion 31 of the first actuation tab 30 may incorporate, in a single piece and through a hinge region 33a, a tab portion 33 which is cut out from the first actuation tab 30 by means of a cutout 34 in the form of a rounded "C", open to the hinge region 33a and allowing said tab portion 33 to define the portion of the first actuation tab 30 affixed to the retention element 35, externally to the vent panel 11.

[0025] The extracting end portion 31 of the first actuation tab 30 may further incorporate an end lower tooth 36, positioned over the rupture line 11a of the vent panel 11, in a region external to the cutout 34 and to the hinge region 33a of the tab portion 33, in order to be pressed against the confronting spot region lib of said rupture line 11a, breaking the latter in said spot region lib and allowing the ascending angular displacement of the grip portion 32 of the first actuation tab 30 to be effected around the hinge region 33a, until occurring the initial rupture of the vent panel 11 and, with the progressive ascending angular displacement of the first actuation tab 30, obtaining the complete rupture of the rupture line 11a and the consequent complete separation of the vent panel 11 and of the first actuation tab 30 in relation to the can L.

[0026] The manual and angular displacement of the first actuation tab 30, initially around the hinge region 33a of the tab portion 33, causes the initial and eventually localized rupture of the rupture line 11a, when the end lower tooth 36 is provided, the progressive manual, angular and ascending displacement of the actuation tab 30 causes the complete rupture of the rupture line 11a of the vent panel 11, which is then integrally detached from the can L, jointly with the retention element 35, forming the vent opening Al (see figures 4, 5 and 6) which is preferably dimensioned so as to be able to receive a straw, when the user wishes to sorb the beverage in this way, reducing the risk of spilling.

[0027] The present constructive arrangement further comprises a second actuation tab 40, having a punching end portion 41 affixed externally to the pouring panel 12 by means of a retention element 45, of any known construction known and which, for example, may take the form of rivet 45a, hermetically incorporated to the pouring panel 12 of the end wall 10, and a grip end portion 42, of annular shape, which may be manually and angularly displaced away from the wall 10 of the can L, after the first actuation tab 30 is removed, in order to break the rupture line 12a of the pouring panel 12 and separate totally the latter from the end wall 10 of the can L, forming the pouring opening A2 (see figures 5 and 6) . This construction allows the axial projection of the rupture line 11a of the vent panel 11 to be contained in the interior of the annular shape of the grip portion 42 of the second actuation tab 40.

[0028] The punching end portion 41 of the second actuation tab 40 incorporates, in a single piece and through a hinge region 43a, a tab portion 43 which is cut out from the second actuation tab 40 by means of a cutout 44 in the form of a rounded "C", open to the hinge region 43a and which allows said tab portion 43 to define the portion of the second actuation tab 40 that is affixed to the retention element 45, externally to the pouring panel 12.

[0029] The punching end portion 41 of the second actuation tab 40 further incorporates an end lower tooth 46, positioned over the rupture line 12a of the pouring panel 12, so as to be pressed against a confronting spot region 12b of the rupture line 12a, external to the cutout 44 and to the hinge region 43a of the tab portion 44, breaking the latter in said spot region 12b and allowing the ascending angular displacement of the grip portion 42 of the second actuation tab 40 to be effected around the hinge region 43a, until occurring the initial rupture of the pouring panel 12 and, with the progressive ascending angular displacement of the second actuation tab 40, obtaining the complete rupture of the rupture line 12a and the consequent complete separation of the pouring panel 12, of the retention element 45, and of the second actuation tab 40 in relation to the can L.

[0030] In the illustrated construction, the extracting end portion 31 of the first actuation tab 30 is positioned through the grip end portion 42, of annular shape, of the second actuation tab 40, with the grip end portion 32 of the first actuation tab 30 being positioned over the punching end portion 41 of the second actuation tab 40, and with the extracting end portion 31 of the first actuation tab 30 being positioned under the grip end portion 42 of the second actuation tab 40.

[0031] With the construction described above, if the user/consumer wishes to sorb the beverage directly from the can, without using the straw, it is necessary that he/she detaches, initially, the vent panel 11 together with the first actuation tab 30. Subsequently, the user/consumer may provide the manual and angular displacement of the grip portion 42 of the second actuation tab 40, so as to detach it from the end wall 10 of the can L, together with the pouring panel 12.

[0032] As illustrated in figures 1 and 2, in the condition in which the vent panel 11 and the pouring panel 12 are still closed, the first and the second actuation tab 30, 40 remain positioned between the end wall 10 of the can L and the plane of the peripheral edge 21 of the latter, not interfering with the bottom of an identical can L stacked thereon, as illustrated in figure 2.

[0033] Thus, the constructive solution proposed herein allows the user/consumer to choose whether to form only the vent opening Al, by moving the first actuation tab 30, or also form, subsequently, the pouring opening A2 , by displacing the second actuation tab 40. However, it should be noted that any one of said two panels, upon producing a respective opening, is completely detached from the upper wall 10 of the can L, without projecting to the interior of the latter.

[0034] In relation to the description above, it should be understood that the ideal dimensional relationships for the components of the invention, for including variations of size, materials, geometric forms, functions, operation modes, mounting arrangements and usage, will be considered obvious for an expert in the art, and that all the relationships, equivalent to those illustrated in the drawings and described in the specification, should be understood as encompassed by the present invention.

[0035] Thus, while only one way of carrying out the invention has been illustrated herein, it should be understood that modifications as to the shape and formation of the parts can be made, without departing from the protective scope defined in the claims that accompany the present specification.
