DESCRIÇÃO "Lata, e um corpo e um painel para a mesma" 0 presente invento refere-se a uma lata, e a um corpo e a um painel para a mesma.DESCRIPTION " Can, and a body and a panel therefor " The present invention relates to a can, and a body and a panel therefor.
Esta lata de acordo com o invento pode ser do tipo, que tem um chamado fecho de abertura fácil. Um fecho de abertura fácil é um fecho de metal para a lata, no qual pode ser formada uma abertura pela utilização de um ou mais dedos das mãos e sem a necessidade de uma ferramenta de abertura separada. Nesta medida, a lata está provida com uma patilha para a formação de uma abertura no painel da lata. A patilha funciona como uma alavanca. Uma tal lata é conhecida a partir de US 3,930,592. A patilha compreende uma parte de patilha traseira, a qual se destina a ser agarrada pelo utilizador. Pela actuação de alavanca ou pela inclinação da patilha a parte de patilha frontal é actuada. A actuação de alavanca ou a inclinação resulta no rasgo espontâneo de uma abertura inicial no painel. A abertura é definida por uma linha de vincagem. A linha de vincagem é geralmente circunferencial. Com a patilha numa posição vertical é formada uma abertura máxima de rasgo espontâneo. O rasgo da patilha para o exterior resulta na ruptura do painel. Finalmente, pela articulação do painel o mesmo é rasgada a partir da lata e é formada a abertura da lata. A lata de acordo com o invento pode também estar provida com uma abertura menor pela acção de alavanca da patilha, formando assim uma pequena abertura apenas suficiente para esvaziar o conteúdo da lata.This can according to the invention may be of the type, which has a so-called easy-opening closure. An easy-release closure is a metal closure for the can, in which an aperture can be formed by the use of one or more fingers of the hands and without the need for a separate aperture tool. To this extent, the can is provided with a tab for forming an aperture in the can panel. The tab acts as a lever. Such a can is known from US 3,930,592. The tab comprises a rear tab portion, which is intended to be grasped by the user. By the lever action or the tilting of the tab the front tab part is actuated. Lever action or tilting results in the spontaneous tear of an opening opening in the panel. The aperture is defined by a crease line. The crease line is generally circumferential. With the tab in a vertical position a maximum opening of spontaneous tear is formed. The ripping of the tab to the outside results in panel rupture. Finally, by the articulation of the panel the same is torn from the can and the opening of the can is formed. The can according to the invention may also be provided with a smaller opening by the levering action of the tab, thereby forming a small opening only sufficient to empty the contents of the can.
Os utilizadores dos tipos de lata descritos acima enfrentam, por vezes, um problema ao agarrar a parte de patilha traseira. Normalmente, isto requer que a ponta de uma unha ou dedo seja inserida entre o painel e a parte de patilha traseira para iniciar a acção de agarrar. 2Users of the types of cans described above sometimes have a problem grasping the rear tab part. This normally requires the tip of a nail or finger to be inserted between the panel and the rear tab portion to initiate the grasping action. 2
ΕΡ 1 958 882/PT Ο invento tem por objectivo melhorar a acção inicial de agarrar pelo utilizador. Esta melhoria é condicionada por as outras funções da lata e da patilha não serem influenciadas, como o fabrico, enchimento, movimentação e abertura da lata pela patilha. O presente invento é baseado na percepção de que as latas podem ter, após o enchimento e fecho, uma pressão interna, que é inferior à pressão atmosférica. Existe uma diferença de pressão negativa sobre o painel. Esta diferença de pressão negativa pode ser o resultado do enchimento a quente e/ou da cozedura do conteúdo da lata antes do fecho da mesma. Após o fecho e arrefecimento a fase gasosa acima do conteúdo reduzir-se-á em volume, formando assim uma diferença de pressão negativa sobre o painel e partes envolventes. Esta diferença de pressão negativa é utilizada para que o painel adquira uma forma côncava ou deprimida. Estas formas resultam num aumento do espaço por debaixo da parte de patilha traseira. O espaço aumentado melhora a acção de agarrar. Obviamente, esta mudança no painel ocorre após o fabrico da lata e do painel, depois do enchimento e fecho. Não existe substancialmente qualquer interferência com o manuseamento tradicional de tais latas.The invention aims to improve the initial grab action by the user. This improvement is conditioned by the other functions of the can and the tab being not influenced, such as the manufacture, filling, movement and opening of the can by the tab. The present invention is based on the perception that the cans may have, after filling and closure, an internal pressure which is lower than atmospheric pressure. There is a negative pressure difference on the panel. This negative pressure difference may be the result of the hot filling and / or firing of the contents of the can before the closing thereof. Upon closure and cooling the gas phase above the content will be reduced in volume, thereby forming a negative pressure difference on the panel and surrounding parts. This negative pressure difference is used so that the panel acquires a concave or depressed shape. These shapes result in an increase in the space below the rear tab portion. Increased space improves gripping action. Obviously, this panel change occurs after the manufacture of the can and the panel, after filling and closing. There is substantially no interference with the traditional handling of such cans.
Por conseguinte, o presente invento proporciona um painel de acordo com a reivindicação 12, um corpo de acordo com a reivindicação 11 e uma lata de acordo com a reivindicação 1. 0 painel de deflexão pode ser formado, proporcionando o painel com uma estrutura particular e/ou proporcionando o painel na zona de deflexão do painel com uma espessura diferente. É requerido, essencialmente, que a zona de deflexão do painel tenha uma flexibilidade maior do que as outras partes do painel, de tal modo que pela diferença de pressão negativa seja proporcionada a forma côncava por debaixo da parte de patilha traseira.Accordingly, the present invention provides a panel according to claim 12, a body according to claim 11 and a can according to claim 1. The deflection panel may be formed, providing the panel with a particular structure and / or providing the panel in the deflection zone of the panel of a different thickness. It is essentially required that the deflection zone of the panel has a greater flexibility than the other parts of the panel such that by the negative pressure difference the concave shape is provided below the rear tab portion.
Faz-se notar que os frascos, as latas e as garrafas para sumo de frutas e compotas podem estar providas com uma tampa de rosca, que tem uma zona de painel de deflexão semelhante. No entanto, estas tampas de rosca não estão providas com uma patilha. 3 ΕΡ 1 958 882/ΡΤIt should be noted that the bottles, cans and bottles for fruit juice and jams may be provided with a screw cap, which has a similar deflecting panel zone. However, these screw caps are not provided with a tab. 3 Ε 1 958 882 / ΡΤ
De acordo com uma primeira concretização a zona de deflexão do painel deflecte entre uma forma côncava e uma forma plana dependendo da diferença de pressão negativa sobre o painel. Assim, quando a diferença de pressão negativa é neutralizada as partes de painel de deflexão deflectem de uma forma côncava para uma forma substancial plana.According to a first embodiment the deflection zone of the panel deflects between a concave shape and a flat shape depending on the negative pressure difference on the panel. Thus, when the negative pressure difference is neutralized the deflection panel parts deflect from a concave shape to a substantially flat shape.
De acordo com outra concretização a zona de deflexão do painel deflecte entre uma forma côncava e uma forma convexa dependendo de uma de pressão negativa sobre o painel. 0 fornecimento de uma forma convexa para a parte do painel de deflexão não interfere com a acção de abertura, ao utilizar a patilha, porque a patilha está então numa posição mais inclinada afastada da zona de deflexão do painel.According to another embodiment the deflection zone of the panel deflects between a concave shape and a convex shape depending on one of negative pressure on the panel. The provision of a convex shape for the deflecting panel part does not interfere with the opening action when using the tab, because the tab is then in a more inclined position remote from the deflection zone of the panel.
De acordo com uma concretização preferida, a zona de deflexão do painel é parte de uma estrutura em socalcos. Assim, existe uma zona melhor controlada na estrutura em socalcos, na qual pode ter lugar a deflexão da parte do painel de deflexão. Em relação a isto, é preferido numa perspectiva do consumidor que a zona de deflexão do painel seja uma estrutura em socalcos central.According to a preferred embodiment, the deflection zone of the panel is part of a terraced structure. Thus, there is a better controlled zone in the terraced structure in which deflection of the deflection panel portion may take place. In this regard, it is preferred from a consumer perspective that the panel deflection zone is a central terraced structure.
De acordo com uma outra concretização, o painel está provido com uma forma inclinada ou gradualmente em depressão (quando existe a diferença de pressão negativa). No entanto, quando a diferença de pressão é neutralizada, a zona de deflexão do painel deflecte da forma côncava inclinada para uma forma plana ou convexa. A fim de, ou de precisamente, definir ou limitar a posição substancialmente horizontal da patilha, antes da abertura da lata, é preferido que o movimento da patilha seja limitado por uma estrutura de assentamento do painel. De acordo com uma concretização, a estrutura de painel tem a forma de uma depressão, na qual a patilha pode assentar ou por cuja depressão o movimento descendente da parte da patilha está limitado. Embora seja preferido que a zona de deflexão do painel esteja localizada na parte central do painel, outras localizações descentradas são também adequadas. 4According to another embodiment, the panel is provided with an inclined or gradually depressed shape (when there is a negative pressure difference). However, when the pressure difference is neutralized, the deflection zone of the panel deflects from the inclined concave shape to a flat or convex shape. In order, or precisely, to define or limit the substantially horizontal position of the tab before opening the can, it is preferred that the movement of the tab is limited by a panel seating structure. According to one embodiment, the panel structure is in the form of a depression, in which the tab can seat or by whose depression the downward movement of the tab portion is limited. While it is preferred that the panel deflection zone is located in the central portion of the panel, other off-center locations are also suitable. 4
ΕΡ 1 958 882/PT Ο painel pode estar ligado ao corpo da lata, por qualquer meio conhecido. 0 painel pode ser unitário com o corpo ou pode estar ligado por quaisquer meios, tais como soldadura, ligação por costura e semelhante. É preferido que o painel seja ligado por costura ao corpo da lata.The panel may be connected to the body of the can by any known means. The panel may be unitary with the body or may be connected by any means, such as welding, seaming, and the like. It is preferred that the panel is seamed to the can body.
As características mencionadas e outras da lata, do corpo e do painel, de acordo com o invento, serão adicionalmente ilustradas por meio dos exemplos que se seguem, os quais são dados com fins ilustrativos e não se destinam a limitar de qualquer forma o presente invento, fazendo ao mesmo tempo referência aos desenhos que se seguem.The aforementioned and other features of the can, the body and the panel according to the invention will be further illustrated by the following examples, which are given for illustrative purposes and are not intended to limit the present invention in any way , while referring to the drawings which follow.
Nos desenhos: a FIG. 1 é uma vista em perspectiva de uma lata de acordo com o invento; as FIGS. 2A e 2B são uma secção pela linha II-II dada na FIG. 1 e que mostram a deflexão da zona de deflexão do painel de acordo com o invento; as FIGS. 3A e 3B mostram uma alternativa da lata de acordo com o invento, e as FIGS. 4A/4B e 5A/5B mostram outras alternativas. A FIG. 1 mostra uma lata 1 de acordo com o invento. A lata compreende um corpo 2, um painel de topo 3 e um painel de fundo 4. 0 painel de topo 3 e o painel de fundo 4 são ligados por costura através de uma ligação por costura 5 ao corpo 2. 0 painel de topo 3 está provido com uma patilha tradicional 6. A patilha 6 compreende uma parte dianteira de patilha 7 e uma parte traseira de patilha 8. A parte traseira de patilha 8 está provida com uma abertura 9, dentro da qual pode ser inserido o dedo do utilizador. A patilha 6 está ligada ao painel de topo 3 através de um rebite 10. Outros métodos para a ligação da patilha 6 incluem soldadura com metal ou material de soldadura plástico. O rebite 10 pode ser um rebite separado ou pode ter sido formado 5In the drawings: FIG. 1 is a perspective view of a can according to the invention; FIGS. 2A and 2B are a section along the line II-II given in FIG. 1 and showing the deflection of the deflection zone of the panel according to the invention; FIGS. 3A and 3B show an alternative of the can according to the invention, and FIGS. 4A / 4B and 5A / 5B show other alternatives. FIG. 1 shows a can 1 according to the invention. The can comprises a body 2, a top panel 3 and a bottom panel 4. The top panel 3 and the bottom panel 4 are seam-connected through a seam 5 to the body 2. The top panel 3 is provided with a traditional tab 6. The tab 6 comprises a tab front portion 7 and a tab back portion 8. The tab back portion 8 is provided with an aperture 9 into which the user's finger can be inserted. The tab 6 is attached to the top panel 3 through a rivet 10. Other methods for attaching the tab 6 include welding with metal or plastic welding material. The rivet 10 may be a separate rivet or may have been formed 5
ΕΡ 1 958 882/PT de material proveniente do painel de topo e conformado com uma forma de rebite. 0 painel está provido com uma linha de vincagem 11, a qual tem uma forma circular. A linha de vincagem define a abertura da lata 1. A lata é aberta pela inserção de um dedo ou unha por debaixo da parte de aba traseira 8 num chamado espaço de agarrar 12. A actuação de alavanca ou a inclinação da patilha 6 tem como resultado num rasgo espontâneo na parte de patilha frontal 7 na linha de vincagem 11 por um movimento ilustrado na FIG. 2B. A FIG. 2A mostra, mais em pormenor e em secção transversal, o painel de topo 3, de acordo com o invento. 0 painel de topo 3 está provido com uma estrutura em socalcos 13 com três anéis concêntricos em socalcos 14 a 16 numa posição mais baixa em relação à costura 5. A estrutura em socalcos compreende uma zona central, que é uma zona de deflexão de painel 17 de acordo com o invento. Como mostrado na FIG. 2A a zona de deflexão de painel 17 tem uma estrutura côncava, devido ao facto de existir uma diferença de pressão negativa sobre o painel de dentro para fora. Isto é, a pressão atmosférica no exterior é maior do que a pressão interna no interior 18 da lata 1, de acordo com o invento.And of material from the top panel and formed into a rivet shape. The panel is provided with a crease line 11, which has a circular shape. The crease line defines the opening of the can 1. The can is opened by inserting a finger or a fingernail underneath the back flap portion 8 into a so-called catch space 12. The lever action or the inclination of the catch 6 results in in a spontaneous feature on the front tab portion 7 in the crease line 11 by a movement shown in FIG. 2B. FIG. 2A shows, in more detail and in cross section, the top panel 3 according to the invention. The top panel 3 is provided with a terrace structure 13 with three concentric terraced rings 14 to 16 at a lower position relative to the seam 5. The terraced structure comprises a central zone, which is a panel deflection zone 17 according to the invention. As shown in FIG. 2A the panel deflection zone 17 has a concave structure, due to the fact that there is a negative pressure difference on the panel from the inside out. That is, the outside atmospheric pressure is greater than the internal pressure in the interior 18 of the can 1 according to the invention.
Faz-se notar que o movimento descendente da patilha 6 na sua parte de patilha traseira está limitado pela presença de uma estrutura de assentamento que tem a forma de uma depressão 19.It is noted that the downward movement of the tab 6 in its rear tab portion is limited by the presence of a seating structure in the form of a depression 19.
Após o rasgo espontâneo abrir o painel 3, formando assim uma abertura de rasgo espontâneo 20, a diferença de pressão é neutralizada, o que resulta numa deflexão da zona de deflexão de painel 17 da forma côncava ilustrada na FIG. 2A para a forma convexa ilustrada na FIG. 2B.After the spontaneous tear opens the panel 3, thus forming a spontaneous tear aperture 20, the pressure difference is neutralized, which results in a deflection of the panel deflection zone 17 of the concave shape shown in FIG. 2A for the convex shape shown in FIG. 2B.
Obviamente, tendo uma forma côncava, como ilustrado na FIG. 2A existe um espaço de agarrar maior e aumentado 12 por debaixo da parte de patilha traseira 8 e do painel 3 na localização da parte de painel de deflexão 17. 6Obviously, having a concave shape, as shown in FIG. 2A there is a larger and increased take up space 12 below the rear lug portion 8 and the panel 3 at the location of the deflection panel part 17. 6
ΕΡ 1 958 882/PTΕΡ 1 958 882 / EN
As FIGS. 3A e 3B mostram uma alternativa da lata 21, de acordo com o invento. A lata está provida com um painel de 22 tendo uma forma inclinada. 0 painel central tem uma zona central 23 (pelo menos, por debaixo da parte de patilha traseira 8 da patilha 6), formando assim o espaço de agarrar 12 por debaixo da parte de patilha traseira 8. 0 painel de 22 está soldado ao corpo 24. Devido ao conteúdo quente da lata 21, após o fecho, existirá uma pressão interna, a qual é inferior à pressão atmosférica e, consequentemente, existe uma diferença de pressão negativa sobre o painel de 22. Devido a esta diferença de pressão negativa o painel de deflexão 23 tem uma forma côncava. 0 rasgo espontâneo abre o painel de 22 por actuação de alavanca ou inclinação da patilha 6, a zona de deflexão de painel 23 deflecte para uma forma convexa.FIGS. 3A and 3B show an alternative of the can 21, according to the invention. The can is provided with a panel 22 having an inclined shape. The center panel has a central zone 23 (at least below the rear lug portion 8 of the tab 6), thereby forming the catch space 12 below the rear tab portion 8. The panel 22 is welded to the body 24 Due to the hot contents of the can 21, after the closure there will be an internal pressure which is lower than the atmospheric pressure and consequently there is a negative pressure difference on the panel 22. Due to this negative pressure difference the panel of deflection 23 has a concave shape. The spontaneous feature opens the panel 22 by lever actuation or tilting of the tab 6, the panel deflection zone 23 deflects to a convex shape.
As FIGS. 4A e 4B mostram uma outra lata 25 de acordo com o invento. 0 painel de topo 26 tem uma zona central de painel de deflexão 27, a qual tem em secção transversal uma forma ondulada. Esta forma ondulada define uma depressão 28 por debaixo a parte de patilha traseira 8 formando assim o espaço de agarrar aumentado 12. A FIG. 4B mostra que, quando da abertura da lata 25 com a patilha 6 e, após ter sido equilibrada a pressão sobre o painel de topo 26, o painel de deflexão 2 7 mudou de forma, de tal modo que a depressão 28 é transformada numa zona mais plana 29. No entanto, a linha de tendência 30 mudou de uma forma substancialmente côncava para uma forma substancialmente convexa.FIGS. 4A and 4B show another can 25 according to the invention. The top panel 26 has a central deflection panel zone 27, which is in cross-section a wavy shape. This undulated shape defines a depression 28 below the rear tab portion 8 thereby forming the increased grab space 12. FIG. 4B shows that upon opening of the can 25 with the tab 6 and, after the pressure has been balanced on the top panel 26, the deflection panel 27 has changed shape such that the depression 28 is transformed into a zone more flat surface 29. However, the trend line 30 has changed from a substantially concave shape to a substantially convex shape.
As FIGS. 5A/5B mostram uma outra lata 31 de acordo com o invento. A lata 31 tem um painel 32 que compreende uma zona de deflexão de painel, que tem uma depressão anelar 34 e uma porção central plana 35. Após a neutralização da diferença de pressão negativa sobre o painel de 32, a zona de deflexão de painel 33 muda da forma representada na FIG. 5A para a forma representada na FIG. 5B, pelo que a depressão 34 desaparece e a porção central 35 move-se para cima. De novo, a linha de 7 ΕΡ 1 958 882/ΡΤ tendência 36 mudou de uma forma substancialmente côncava para uma forma substancialmente convexa. A lata, o corpo e/ou painel podem ser feitos em metal, tal como o alumínio e o aço.FIGS. 5A / 5B show another can 31 according to the invention. The can 31 has a panel 32 which comprises a panel deflection zone having an annular depression 34 and a planar center portion 35. Upon neutralization of the negative pressure difference on the panel 32, the panel deflection zone 33 changes as shown in FIG. 5A for the shape shown in FIG. 5B, whereby the depression 34 disappears and the central portion 35 moves upwards. Again, the line 7 has a substantially concave shape to a substantially convex shape. The can, the body and / or panel may be made of metal, such as aluminum and steel.
As latas podem ser redondas ou não redondas (oval e retangular) . Quando é redonda a lata pode ter um diâmetro de cerca de 52 a 153 mm. Com diâmetros menores, o painel tendo uma estrutura em socalcos terá cerca de 1 ou 2 socalcos, mas com diâmetros maiores, o número de socalcos pode aumentar. A vantagem de tais estruturas em socalcos é proporcionar rigidez nas estruturas em socalcos e permitir as melhores propriedades de deflexão flexíveis controladas e ligadas à zona de deflexão do painel, a qual é, em geral, a zona central do painel.The cans can be round or non-round (oval and rectangular). When round the can may have a diameter of about 52 to 153 mm. With smaller diameters, the panel having a terraced structure will have about 1 or 2 terraces, but with larger diameters, the number of terraces may increase. The advantage of such terraced structures is to provide rigidity in terraced structures and to allow the best flexible deflecting properties controlled and connected to the deflection zone of the panel, which is generally the central zone of the panel.
Quando feito em aço, o painel pode ter uma espessura de 0,13 a 0,30 mm. A espessura pode ser menor na zona que forma a zona de deflexão do painel.When made of steel, the panel may have a thickness of 0.13 to 0.30 mm. The thickness may be smaller in the zone forming the deflection zone of the panel.
Faz-se notar novamente que a patilha utilizada pode ser uma patilha convencional. O objecto do invento é proporcionar um espaço melhorado e maior, disponível para o utilizador inserir uma unha e/ou a ponta do dedo por debaixo da parte de patilha traseira, melhorando assim a acção de agarrar e a abertura da lata.It will again be noted that the tab used may be a conventional tab. The object of the invention is to provide an improved and larger space available for the user to insert a finger nail and / or the tip of the finger underneath the rear tab portion, thereby improving the grasping action and the opening of the can.
