TÉCNICA RELACIONADA RELATED TECHNIQUE
(002) É bem conhecido o uso de embalagens descartáveis para acondicionar diferentes tipos de líquidos, notadamente na indústria de laticínios e de sucos de frutos ou similares. Um tipo bem conhecido para este propósito compreende uma embalagem de modo geral em formato paralelepipedal fabricada em um material laminado fibroso e delgado, usualmente papel, ao qual é afixado um segundo material laminado e delgado e de grande resistência, usualmente alumínio. (002) It is well known to use disposable packaging to store different types of liquids, notably in the dairy and fruit juices or similar industries. A well-known type for this purpose comprises a packaging generally in parallelepipedal shape made of a fibrous and thin laminated material, usually paper, to which is attached a second thin and highly resistant laminated material, usually aluminum.
(003) Normalmente são adicionadas camadas de material termoplástico impermeável, usualmente polietileno, que podem ser aplicadas sobre esse material laminado composto e compor camadas intermediárias entre as camadas de papel cartonado e alumínio desse material laminado composto. Este tipo de material tem um custo de fabricação bastante baixo e pode ser facilmente configurado para assumir diversas formas. Isto facilita bastante o processo de fabricação de uma embalagem com este tipo de material. Embalagens desse tipo são denominadas embalagens cartonadas. (003) Normally layers of impermeable thermoplastic material, usually polyethylene, are added, which can be applied on this composite laminated material and compose intermediate layers between the layers of cardboard and aluminum of this composite laminated material. This type of material has a very low manufacturing cost and can be easily configured to take different forms. This greatly facilitates the process of manufacturing a packaging with this type of material. Such packaging is called carton packaging.
(004) No caso de embalagens cartonadas fabricadas com o material laminado acima mencionado, por questões de higiene e segurança alimentar e para evitar a contaminação do produto por microrganismos elas devem ser mantidas em condições assépticas. Consequentemente, as embalagens devem ser hermeticamente fechadas no processo de industrialização e devem permanecer assim até o momento em que seja necessário servir seu conteúdo. Esse tipo de embalagem é conhecido como "embalagem cartonada asséptica". (005) É comum que embalagens cartonadas sejam providas de conjuntos de bocal e tampa, para facilitar a retirada do produto do interior da embalagem. É necessário que seja provido algum meio para que a embalagem possa ser cortada na região onde é aplicado o conjunto de bocal e tampa, para permitir o escoamento do produto acondicionado na embalagem através do bocal. (004) In the case of carton packs manufactured with the aforementioned laminated material, for reasons of hygiene and food safety and to avoid contamination of the product by microorganisms they must be kept in aseptic conditions. Consequently, the packaging must be hermetically sealed in the industrialization process and must remain so until the moment it is necessary to serve its contents. This type of packaging is known as "aseptic carton packaging". (005) It is common for carton packs to be provided with nozzle and cover assemblies, to facilitate the removal of the product from the inside of the package. It is necessary that some means be provided so that the package can be cut in the region where the nozzle and cover assembly is applied, to allow the product stored in the package to flow through the nozzle.
(006) O uso de conjuntos de bocal e tampa em embalagens cartonadas assépticas possibilita fechar a embalagem novamente no caso de somente parte de seu conteúdo ter sido servida. Para isso basta que a tampa seja novamente enroscada no bocal, e o conteúdo remanescente permanecerá vedado no interior da embalagem. (006) The use of nozzle and cap assemblies in aseptic carton packs makes it possible to close the pack again if only part of its contents have been served. For that, it is enough that the cap is screwed back on the nozzle, and the remaining contents will remain sealed inside the package.
(007) São conhecidos diversos tipos de dispositivos de bocal e tampa para uso em embalagens cartonadas assépticas. Um tipo bastante conhecido desses dispositivos de bocal e tampa compreende o uso de um terceiro componente, um elemento rotativo de corte instalado no interior do bocal e que é acionado pela tampa quando ela é desenroscada pela primeira vez do bocal. Consequentemente, o elemento rotativo de corte efetua um corte na camada de alumínio da embalagem, abrindo uma passagem para que o conteúdo no interior da embalagem possa passar através do bocal para ser servido. Este tipo de dispositivo que compreende bocal, tampa e elemento cortante é conhecido pela expressão "dispositivo para abertura automática". (007) Various types of mouthpiece and cap devices are known for use in aseptic carton packs. A well-known type of these nozzle and cap devices comprises the use of a third component, a rotary cutting element installed inside the nozzle and which is activated by the cap when it is unscrewed for the first time from the nozzle. Consequently, the rotating cutting element cuts the aluminum layer of the package, opening a passage so that the contents inside the package can pass through the nozzle to be served. This type of device comprising a nozzle, cover and cutting element is known by the term "device for automatic opening".
(008) Para que esse tipo de dispositivo para abertura automática de embalagens cartonadas assépticas possa operar corretamente é necessário que seja provido um orifício na camada de papelão na etapa de fabricação da matéria prima para posterior fabricação de embalagens cartonadas assépticas, antes do processo de lamiinação das camadas que complementam essa matéria prima para a fabricação das embalagens cartonadas assépticas. Esse orifício deve ser localizado exatamente na região onde será aplicado o dispositivo para abertura automática, o que possibilitará a abertura da embalagem. (008) In order for this type of device to automatically open aseptic carton packs to operate correctly, it is necessary to provide a hole in the cardboard layer in the raw material manufacturing step for later manufacture of aseptic carton packs, before the lamination process. of the layers that complement this raw material for the manufacture of aseptic carton packs. This hole must be located exactly in the region where the device for automatic opening will be applied, which will make it possible to open the packaging.
(009) No presente relatório descritivo as expressões "abrir a embalagem" ou "abertura da embalagem" devem ser entendidas como a operação de efetuar o corte da camada de alumínio da embalagem que fica abaixo do orifício na camada de papel cartonado. A base ou flange do bocal do dispositivo para abertura automática é aplicada à embalagem de maneira que a linha de centro do bocal fique substancialmente alinhada ao centro do orifício. (009) In this specification, the terms "opening the package" or "opening the package" should be understood as the operation of cutting the aluminum layer of the packaging that is below the hole in the layer of cardboard. The base or flange of the mouthpiece of the automatic opening device is applied to the packaging so that the centerline of the mouthpiece is substantially aligned with the center of the hole.
(010) São conhecidos diversos modelos de dispositivos abertura automática de embalagens cartonadas assépticas. Os documentos de patente US7036683, W02004/000667, W02006/050624, W02007/113216, W02007/113216 e WO2007/115978 descrevem alguns modelos desses dispositivos, os conteúdos dos quais são incluídos ao presente relatório para referência. (010) Several models of automatic opening devices for aseptic carton packs are known. Patent documents US7036683, W02004 / 000667, W02006 / 050624, W02007 / 113216, W02007 / 113216 and WO2007 / 115978 describe some models of these devices, the contents of which are included in this report for reference.
(011) Em todos os dispositivos de abertura automática de embalagens cartonadas assépticas mencionados no parágrafo anterior a tampa é provida de meios de acionamento para causar o movimento do elemento rotativo de corte, mas a tampa ao ser desenroscada do bocal se afasta do elemento rotativo de corte, o que cria uma dificuldade para o acionamento desse último. (011) In all the automatic opening devices for aseptic carton packs mentioned in the previous paragraph, the cover is provided with actuation means to cause the movement of the rotating cutting element, but when the cap is unscrewed from the nozzle it moves away from the rotating element of cut, which makes it difficult to activate the latter.
(012) A solução para resolver esse problema foi alongar os elementos de acionamento da tampa em direção ao interior do bocal, de maneira a compensar o referido afastamento entre a tampa e o elemento rotativo de corte. Esse alongamento dos elementos de acionamento da tampa causa um aumento significativo no peso da tampa, devido a um aumento no consumo de matéria prima. Dependendo dos critérios de projeto adotados, pode também causar um aumento das dimensões do dispositivo para abertura automática, e causar dificuldades para o empilhamento das embalagens, em decorrência do aumento de extensão provocado pelas dimensões maiores do dispositivo. (012) The solution to solve this problem was to elongate the cover drive elements towards the inside of the nozzle, in order to compensate for the referred gap between the cover and the rotating cutting element. This elongation of the lid driving elements causes a significant increase in the lid weight, due to an increase in the consumption of raw materials. Depending on the design criteria adopted, it can also cause an increase in the dimensions of the device for automatic opening, and cause difficulties for stacking the packages, due to the increase in extension caused by the larger dimensions of the device.
(013) No documento W02016/082008, de titularidade da depositante do presente pedido e cujo conteúdo é incluído ao presente relatório descritivo, para referência, descreve- se um dispositivo para abertura automática de embalagens cartonadas assépticas que utiliza uma rosca provida de veios com orientações opostas. Em decorrência ao uso desse tipo de rosca, o dispositivo para abertura automática revelado no documento W02016/082008 compreende apenas dois componentes, um bocal e uma tampa com um elemento rotativo de corte afixado à sua porção interior. (013) Document W02016 / 082008, owned by the depositor of this application and whose content is included in this specification, for reference, describes a device for automatic opening of aseptic carton packs using a thread provided with veins with orientations opposite. Due to the use of this type of thread, the device for automatic opening revealed in document W02016 / 082008 comprises only two components, a nozzle and a cover with a rotating cutting element affixed to its inner portion.
(014) O dispositivo para abertura automática de embalagens cartonadas assépticas revelado no documento W02016/082008 compreende o uso de um bocal cuja região externa é provida de uma rosca externa que compreende um primeiro veio seguido de um segundo veio de orientação oposta uma tampa provida de segmentos de rosca interna que se enroscam na rosca externa do bocal. (014) The device for automatic opening of aseptic carton packs disclosed in document W02016 / 082008 comprises the use of a nozzle whose outer region is provided with an external thread comprising a first shaft followed by a second shaft of opposite orientation and a lid provided with internal thread segments that screw into the external thread of the nozzle.
(015) A operação do dispositivo para abertura automática de embalagens cartonadas assépticas para efetuar a abertura de uma embalagem é detalhadamente descrita no documento W02016/082008. Por meio da leitura do relatório descritivo desse documento pode ser observada a simplicidade e a eficiência do dispositivo para efetuar a abertura da embalagem, em decorrência do uso da rosca provida de veios com orientações opostas. (015) The operation of the device for automatic opening of aseptic carton packs to effect the opening of a pack is described in detail in document W02016 / 082008. By reading the descriptive report of this document, it is possible to observe the simplicity and efficiency of the device for opening the package, due to the use of the thread provided with veins with opposite orientations.
(016) Igualmente ao que ocorre com os demais dispositivos para abertura automática de embalagens cartonadas assépticas, o dispositivo revelado no documento W02016/082008 possibilita que a embalagem seja novamente fechada depois da abertura. Para isso basta enroscar a tampa novamente no bocal. (016) As with other devices for automatic opening of aseptic carton packs, the device disclosed in document W02016 / 082008 allows the package to be closed again after opening. To do this, simply screw the cap back onto the nozzle.
(017) O documento de patente BR 10 2019 003243 0, de titularidade comum à depositante do presente pedido e cujo teor é integralmente adicionado a este relatório descritivo, para referência, descreve um dispositivo para abertura automática de embalagens cartonadas assépticas similar ao que é descrito no documento W02016/082008, o qual tem a característica de ser provido de um dispositivo destacável de corte. (017) Patent document BR 10 2019 003243 0, common to the depositor of this application and whose content is integrally added to this specification, for reference, describes a device for automatic opening of aseptic carton packs similar to the one described in document W02016 / 082008, which has the characteristic of being provided with a detachable cutting device.
(018) Como nos dispositivos para abertura automática de embalagens cartonadas assépticas revelados nos documentos W02016/082008 e BR 10 2019 003243 0 a rosca do bocal é provida de veios com orientações opostas, um primeiro veio de orientação à direita seguido de um segundo veio de orientação à esquerda, quando os segmentos de rosca interna da tampa entrarem no segundo veio a tampa irá efetuar um movimento de subida, em decorrência da orientação a esquerda do segundo veio da rosca do bocal. (018) As in the devices for automatic opening of aseptic carton packs revealed in documents W02016 / 082008 and BR 10 2019 003243 0 the nozzle thread is provided with shafts with opposite orientations, a first orientation shaft on the right followed by a second shaft Left orientation, when the internal threads of the cap enter the second shaft, the cap will make an upward movement due to the left orientation of the second shaft of the nozzle thread.
(019) Isso poderá criar alguma estranheza para os consumidores, acostumados a utilizar somente bocais providos com roscas de orientação à direita, nos quais a tampa efetua somente um movimento de descida quando é enroscada no bocal para fechar a embalagem. Como resultado, poderá haver situações em que os consumidores não enrosquem totalmente a tampa na rosca provida de veios com orientações opostas do bocal. Isso significa que a embalagem não ficaria totalmente fechada nessas situações. Isso poderia causar vazamentos do produto contido na embalagem caso ela fosse colocada em uma posição apoiada sobre suas faces laterais, o que ocorre frequentemente quando são armazenadas em refrigeradores. (020) A presente invenção revela um dispositivo para abertura automática de embalagens cartonadas assépticas provido de meios para evitar tais situações e garantir que cada segmento de rosca interna da tampa, depois que esta última for desenroscada do bocal pela primeira vez, somente possa ser novamente enroscado no primeiro veio da rosca do bocal ou em veio suplementar paralelo ao primeiro veio da rosca do bocal. Isso evita que usuários inadvertidamente possam deixar a embalagem parcialmente aberta, por não estarem acostumados ao uso de bocais providos de roscas com veios de orientações opostas. Ao final desse o enroscamento a embalagem estará perfeitamente fechada. (019) This may create some awkwardness for consumers, who are used to only using nozzles provided with right-hand threaded screws, in which the lid only makes a downward movement when it is screwed into the nozzle to close the packaging. As a result, there may be situations where consumers do not fully screw the cap on the thread provided with shafts with opposite orientations of the nozzle. This means that the packaging would not be completely closed in these situations. This could cause leaks of the product contained in the packaging if it were placed in a position supported on its side faces, which often occurs when they are stored in refrigerators. (020) The present invention discloses a device for automatic opening of aseptic carton packs provided with means to prevent such situations and to ensure that each internal thread segment of the lid, after the latter is unscrewed from the nozzle for the first time, can only be re-used. screwed on the first nozzle thread shaft or on a supplementary shaft parallel to the first nozzle thread shaft. This prevents users from inadvertently leaving the packaging partially open, as they are not accustomed to using nozzles provided with threads with opposite orientation shafts. At the end of the screwing, the packaging will be perfectly closed.
(021) Essas e outras características da presente invenção ficarão aparentes por meio da descrição detalhada da invenção que será feita mais adiante. (021) These and other features of the present invention will be apparent from the detailed description of the invention to be made later.

(027) As Figuras IA e 1B retratam, respectivamente, uma vista frontal e uma vista em perspectiva de uma primeira concretização do dispositivo para abertura automática de embalagens cartonadas assépticas 1 objeto da presente invenção, o qual compreende um bocal 10, uma tampa 20 e um elemento de corte 30, em que o bocal 10 e a tampa 20 são retratados nas Figuras IA e 1B antes de serem montados, para formar o dispositivo. (027) Figures IA and 1B show, respectively, a front view and a perspective view of a first embodiment of the device for automatic opening of aseptic carton packs 1 object of the present invention, which comprises a nozzle 10, a lid 20 and a cutting element 30, in which the nozzle 10 and the cap 20 are pictured in Figures IA and 1B before being assembled, to form the device.
(028) Pode ser observado que o dispositivo para abertura automática 1 compreende um bocal 10 provido de uma rosca externa 11 a qual inclui um primeiro veio 11b conectado a um segundo veio 11a de orientação oposta. A rosca 11 deve ter ao menos uma entrada, embora nas Figuras IA e 1B ela seja representada com três entradas, o que confere mais estabilidade para o enroscamento de tampas. (028) It can be seen that the device for automatic opening 1 comprises a nozzle 10 provided with an external thread 11 which includes a first shaft 11b connected to a second shaft 11a of opposite orientation. Thread 11 must have at least one entry, although in Figures IA and 1B it is represented with three entries, which provides more stability for screwing on covers.
(029) A região inferior do bocal 10 é afixada a um elemento de base ou flange 12, cuja região inferior é projetada para ser afixada à camada de papel cartonado de uma embalagem cartonada asséptica por meio de colagem ou processo similar, com o bocal localizado de maneira que seu eixo de simetria seja substancialmente coincidente com o eixo de simetria do referido orifício feito na camada de papel cartonado.

(030) O dispositivo de abertura automática 1 compreende também uma tampa 20 provida de segmentos de rosca interna 21 os quais são projetados para serem enroscados na rosca 11 do bocal 10. A tampa 20 deve ser provida de ao menos um segmento de rosca interna 21. Na Figura são representados três segmentos de rosca interna 21, em decorrência de ser usada no bocal 10 uma rosca 11 com três entradas. (030) The automatic opening device 1 also comprises a cover 20 provided with internal thread segments 21 which are designed to be screwed into the thread 11 of the nozzle 10. The cover 20 must be provided with at least one internal thread segment 21 The figure shows three internal thread segments 21, as a thread 11 with three inlets is used in the nozzle 10.
(031) Conforme mencionado anteriormente, apenas para efeitos descritivos a presente descrição considera um dispositivo para abertura automática de embalagens cartonadas assépticas que incorpora características reveladas no documento BR 10 2019 003243 0, e como tal a tampa 30 incorpora também um elemento de acionamento 26, cuja função é descrita no referido documento BR 10 2019 003243 0, e que não será objeto de descrição no presente relatório por não ser parte do conceito inventivo da presente invenção. Consequentemente, e reiterando o que já fora anteriormente mencionado, a configuração da tampa 20 não está limitada à representação que dela se faz nas Figuras IA e 1B. (031) As previously mentioned, for the purposes of description only, this description considers a device for automatic opening of aseptic carton packs that incorporates features revealed in document BR 10 2019 003243 0, and as such the lid 30 also incorporates a drive element 26, whose function is described in the referred document BR 10 2019 003243 0, and which will not be described in this report because it is not part of the inventive concept of the present invention. Consequently, and reiterating what has already been mentioned, the configuration of the lid 20 is not limited to the representation that is made of it in Figures IA and 1B.
(032) O elemento de corte 30 afixado à região superior interna do bocal 10 representado nas Figuras IA e 1B é apenas uma das diversas opções conhecidas para a configuração desse componente, tendo sido essa configuração escolhida apenas para efeitos descritivos, a qual se refere a uma das concretizações de dispositivo de abertura automática de embalagens cartonadas assépticas reveladas no referido documento BR 10 2019 003243 0, e que não será objeto de descrição no presente relatório por não ser parte do conceito inventivo da presente invenção. Consequentemente, e reiterando o que já fora anteriormente mencionado, a configuração do elemento de corte 30 não está limitada à representação que dele se faz nas Figuras IA e 1B. (032) The cutting element 30 affixed to the upper internal region of the nozzle 10 shown in Figures IA and 1B is only one of several options known for the configuration of this component, this configuration having been chosen only for descriptive purposes, which refers to one of the embodiments of the automatic opening device for aseptic carton packs revealed in the referred document BR 10 2019 003243 0, and which will not be described in this report because it is not part of the inventive concept of the present invention. Consequently, and reiterating what has already been mentioned, the configuration of the cutting element 30 is not limited to the representation made of it in Figures IA and 1B.
(033) De acordo com as diversas concretizações da invenção do referido documento BR 10 2019 003243 0, o elemento de corte 30 pode ser afixado ao bocal 10 ou ao elemento de acionamento 26 da tampa 20 por meio de uma pluralidade de elementos de ruptura . Dependendo de qual componente ao qual o elemento de corte 30 for afixado, seja ao bocal 10 ou ao elemento de acionamento 26 da tampa 20, o elemento de corte 30 será destacado desse componente ou na fase de montagem dos componentes do dispositivo para abertura automática de embalagens 1, operação feita em fábrica, ou quando a tampa 20 for desenroscada do bocal 10 pela primeira vez. (033) According to the various embodiments of the invention of said document BR 10 2019 003243 0, the cutting element 30 can be affixed to the nozzle 10 or to the driving element 26 of the cover 20 by means of a plurality of rupture elements. Depending on which component to which the cutting element 30 is attached, either to the nozzle 10 or to the driving element 26 of the cover 20, the cutting element 30 will be detached from that component or in the assembly phase of the device components for automatic opening of packages 1, factory operation, or when the cap 20 is unscrewed from the nozzle 10 for the first time.
(034) Qualquer que seja a configuração adotada para a afixação do elemento de corte 30 a outro dos componentes do dispositivo para abertura automática de embalagens 1, seja ao bocal 10 ou ao elemento de acionamento 26 da tampa 20, tal característica não interferirá na operação do dispositivo para abertura automática de embalagens 1 da presente invenção. (035) As Figuras 2 a 5 retratam etapas da operação de desenroscar pela primeira vez a tampa 30 em relação ao bocal 10 do dispositivo para abertura automática de embalagens cartonadas assépticas 1 retratado nas Figuras IA e 1B. Para facilitar a compreensão, nas Figuras 2 a 5 foram representados apenas os segmentos de rosca interna 21 da tampa 20. Como os segmentos de rosca interna 21 são solidários à tampa 20, evidentemente, quaisquer movimentos que eles façam serão obrigatoriamente os mesmos efetuados pela tampa 20. (036) Na Figura 2 o dispositivo para abertura automática de embalagens cartonadas assépticas 1 é representado em uma situação em que seus componentes já foram devidamente montados, operação feita em fábrica. Pode ser observado na Figura 2 como os segmentos de rosca interna 21 da tampa 30 estão localizados na região posterior do segundo veio 11a da rosca 11 do bocal 10, posição em que ficam depois de a tampa 20 e o bocal 10 serem montados em fábrica para formar o dispositivo para abertura automática de embalagens cartonadas assépticas 1. Na Figura 2 somente aparece um dos segmentos de rosca interna 21 da tampa 20, pois, evidentemente, os demais estão encobertos pelo bocal 10. (034) Whatever the configuration adopted for affixing the cutting element 30 to another of the device components for automatic opening of packages 1, either to the nozzle 10 or to the driving element 26 of the lid 20, this feature will not interfere with the operation of the device for automatic opening of packages 1 of the present invention. (035) Figures 2 to 5 depict steps in the operation of unscrewing lid 30 for the first time from the nozzle 10 of the device for automatic opening of aseptic carton packs 1 shown in Figures IA and 1B. In order to facilitate understanding, in Figures 2 to 5, only the internal thread segments 21 of the cover 20 are represented. As the internal thread segments 21 are attached to the cover 20, of course, any movements they make will necessarily be the same made by the cover. 20. (036) In Figure 2, the device for automatic opening of aseptic carton packs 1 is represented in a situation in which its components have already been properly assembled, an operation carried out at the factory. It can be seen in Figure 2 how the internal thread segments 21 of the cap 30 are located in the posterior region of the second shaft 11a of the thread 11 of the nozzle 10, position where they are after the cap 20 and the nozzle 10 are assembled in the factory for form the device for automatic opening of aseptic carton packs 1. In Figure 2, only one of the internal thread segments 21 of the lid 20 appears, since, of course, the others are covered by the nozzle 10.
(037) Na Figura 3 o dispositivo para abertura automática de embalagens cartonadas assépticas 1 é representado em uma situação em que já ocorreu o início do primeiro desenroscamento da tampa 20 em relação ao bocal 10, por meio da aplicação de uma rotação no sentido anti-horário à tampa 20. Consequentemente, os segmentos de rosca interna 21 da tampa 30 percorreram quase toda a extensão dos segundos veios 11a da rosca 11 do bocal 10. Como os segundos veios 11a têm orientação à esquerda, consequentemente a tampa 20 efetua um movimento axial descendente no decorrer desse percurso dos segmentos de rosca interna 21 nos segundos veios 11a da rosca 11 do bocal 10. (037) In Figure 3, the device for automatic opening of aseptic carton packs 1 is represented in a situation where the first unscrewing of the lid 20 in relation to the nozzle 10 has already occurred, by applying a rotation in the anti- clockwise to the cap 20. Consequently, the inner thread segments 21 of the cap 30 have traveled almost the entire length of the second shafts 11a of the thread 11 of the nozzle 10. As the second shafts 11a have left orientation, consequently the cap 20 performs an axial movement descending along that path of the internal thread segments 21 in the second shafts 11a of the thread 11 of the nozzle 10.
(038) A composição dos movimentos de rotação e axial descendente efetuados pela tampa 20 provocaram o acionamento do elemento de corte 30, fazendo com que esse último também efetuasse uma composição de movimentos rotacional anti-horário e axial descendente. Consequentemente, nessa composição de movimentos o elemento de corte 30 efetuou o corte da camada de alumínio da embalagem, como é conhecido na técnica, por exemplo, descrito em detalhes nos documentos W02016/082008 e BR 10 2019 003243 0. Pode ser observado na Figura 3 o elemento de corte 30 já ao final de seu movimento axial descendente. (038) The composition of the rotational and downward axial movements made by the cover 20 caused the cutting element 30 to be activated, causing the latter also make a composition of counterclockwise and descending axial rotational movements. Consequently, in this composition of movements the cutting element 30 made the cutting of the aluminum layer of the packaging, as is known in the art, for example, described in detail in documents W02016 / 082008 and BR 10 2019 003243 0. It can be seen in Figure 3 the cutting element 30 at the end of its downward axial movement.
(039) Na Figura 3 pode ser observado um restritor 11c localizado no segundo veio 11a da rosca 11, imediatamente junto à junção do segundo veio 11a com o primeiro veio 11b da rosca 11. O restritor 11c é projetado para permitir que os segmentos de rosca interna 21 da tampa 20 possam passar sobre si somente no sentido de desenroscamento da tampa 30 em relação ao bocal 10. Em outras palavras, cada segmento de rosca interna 21 da tampa 20 somente poderá passar pelo respectivo restritor 11c quando houver anteriormente percorrido o segundo veio 11a da rosca 11, o que só ocorrerá uma única vez, quando a tampa 20 for desenroscada do bocal 10 pela primeira vez. (039) In Figure 3, a restrictor 11c located on the second shaft 11a of the thread 11 can be seen, immediately next to the junction of the second shaft 11a with the first shaft 11b of the thread 11. The restrictor 11c is designed to allow the thread segments inner 21 of the cap 20 can pass only in the direction of unscrewing of the cap 30 in relation to the nozzle 10. In other words, each internal thread segment 21 of the cap 20 can only pass through the respective restrictor 11c when the second shaft has previously traveled 11a of thread 11, which will only occur once, when the cap 20 is unscrewed from the nozzle 10 for the first time.
(040) Na presente concretização, apenas a título de exemplificação, e não limitativamente, o restritor compreende um prolongamento do filete superior do primeiro veio 11b, em que a face desse prolongamento voltada para o segundo veio 11a da rosca 11 tem a forma de uma cunha, que se inicia da região final do segundo veio 11a e vai se alteando até se encontrar com a cristã do prolongamento de filete, que deve ter uma altura menor para possibilitar que os segmentos de rosca interna 21 possam passar sobre eles quando a tampa 20 for desenroscada do bocal lOpela primeira vez, sem dificultar o desenroscamento da tampa 20. (040) In the present embodiment, just as an example, and not limitingly, the restrictor comprises an extension of the upper thread of the first shaft 11b, in which the face of that extension facing the second shaft 11a of the thread 11 is shaped like a wedge, which starts at the end of the second shaft 11a and rises until it meets the fillet extension Christian, which must be of a lower height to allow the internal thread segments 21 to pass over them when the cap 20 is unscrewed from the nozzle l for the first time, without making it difficult to unscrew the cap 20.
(041) A outra face do restritor 11c formado pelo prolongamento do filete superior do primeiro veio 11b, voltada para o primeiro veio 11b, tem a forma de uma superfície plana, similar a uma parede, o que impedirá que os segmentos de rosca interna 21 possam passar sobre o restritor 11c quando a tampa 20 for enroscada novamente no bocal 10. Outras configurações podem ser empregadas para o restritor 11c, desde que operem da maneira acima descrita. (041) The other face of the restrictor 11c formed by the extension of the upper thread of the first shaft 11b, facing the first shaft 11b, has the shape of a flat surface, similar to a wall, which will prevent the internal thread segments 21 can pass over the restrictor 11c when the cap 20 is screwed back onto the nozzle 10. Other configurations can be used for the restrictor 11c, provided they operate in the manner described above.
(042) Com a continuidade do desenroscamento da tampa 20 em relação ao bocal 10, os segmentos de rosca interna 21 da tampa 20 ultrapassarão o restritor 11c e passarão a percorrer os primeiros veios 11b da rosca 11, conforme retratado na Figura 4. Evidentemente, cada um dos primeiros veios 11b da rosca 11 é provido de um restritor 11c. (042) With the unscrewing of the cap 20 in relation to the nozzle 10, the internal thread segments 21 of the cap 20 will overtake the restrictor 11c and will pass through the first shafts 11b of the thread 11, as shown in Figure 4. Evidently, each of the first shafts 11b of the thread 11 is provided with a restrictor 11c.
(043) Como os primeiros veios 11b têm orientação à direita, consequentemente a tampa 20 passará a efetuar um movimento axial ascendente, conjuntamente ao movimento rotacional de desenroscamento no sentido anti-horário, até que os segmentos de rosca interna 21 da tampa 20 saiam completamente dos primeiros veios 11b da rosca 11, conforme retratado na Figura 5. Ao fim do desenroscamento da tampa 20 a embalagem estará aberta e seu conteúdo poderá ser servido através do bocal 10. (043) As the first shafts 11b are oriented to the right, the cap 20 will consequently start an upward axial movement, together with the movement anti-clockwise rotational unscrewing, until the internal thread segments 21 of the cap 20 completely exit the first shafts 11b of the thread 11, as shown in Figure 5. At the end of the unscrewing of the cap 20 the package will be open and its contents can be served through the nozzle 10.
(044) Assim, nesta primeira concretização da invenção a passagem dos segmentos de rosca interna 21 da tampa 20 pelos segundos veios 11b da rosca 11 do bocal 10 ocorre uma única vez, quando a tampa 20 for desenroscada pela primeira vez do bocal 10, conforme descrito anteriormente. (044) Thus, in this first embodiment of the invention the passage of the internal thread segments 21 of the cap 20 through the second shafts 11b of the thread 11 of the nozzle 10 occurs only once, when the cap 20 is unscrewed for the first time from the nozzle 10, as described earlier.
(045) Para novamente enroscar a tampa 20 no bocal 10 ela deverá ser aposta ao bocal e ser aplicado um movimento rotacional no sentido horário, para que os segmentos de rosca interna 21 da tampa 20 possam iniciar o enroscamento nos primeiros veios 11b da rosca 11, conforme retratado na Figura 5. Em seguida os segmentos de rosca interna 21 percorrerão os primeiros veios 11b da rosca 11 até a junção com o segundo veio 11a, conforme retratado na Figura 7. Como os restritores 11c não permitirão a passagem dos segmentos de rosca interna 21 para os segundos veios 11a, consequentemente o movimento de enroscamento da tampa 20 no bocal 10 estará terminado. (045) To screw the cap 20 onto the nozzle 10 again, it must be affixed to the nozzle and a clockwise rotational movement must be applied, so that the internal threads 21 of the cap 20 can start screwing on the first shafts 11b of the thread 11 , as shown in Figure 5. Then the internal thread segments 21 will travel the first shafts 11b of the thread 11 to the junction with the second shaft 11a, as shown in Figure 7. As the restrictors 11c will not allow the thread segments to pass inner 21 for the second shafts 11a, consequently the screwing movement of the cap 20 in the nozzle 10 will be finished.
(046) Como pôde ser observado por meio da descrição que se fez anteriormente em relação à primeira concretização da invenção, de acordo com os preceitos da presente invenção os segundos veios 11a da rosca 11 servem apenas para propiciar o acionamento do elemento de corte 30, para que esse possa fazer o corte da camada de alumínio da embalagem, propiciando sua abertura. Depois disso os segundos veios 11a não mais têm função. Consequentemente, quando a tampa 20 for novamente enroscada no bocal 10, esse enroscamento ocorrerá somente nos primeiros veios 11b da rosca 11, de orientação à direita, e com isso os consumidores não notarão nenhuma diferença em relação ao que estão acostumados quando enroscam uma tampa em um bocal convencional. (046) As can be seen from the description that was made previously in relation to the first embodiment of the invention, according to the precepts of the present invention the second shafts 11a of the thread 11 serve only to provide the drive of the cutting element 30, so that it can cut the aluminum layer of the package, allowing its opening. After that, the second shafts 11a no longer have a function. Consequently, when the cap 20 is screwed back on the nozzle 10, this screwing will only occur on the first shafts 11b of the thread 11, to the right, and thus consumers will not notice any difference in relation to what they are used to when screwing a cap on a conventional nozzle.
(047) Uma vantagem adicional decorrente de o enroscamento da tampa somente ocorrer nos primeiros veios 11b da rosca 11 é que isso possibilita que a parte inferior do tampo da tampa 20 se assente sobre a borda superior do bocal 10, conforme retratado na Figura 7, o que garante a total vedação da embalagem depois de a tampa 20 ser novamente enroscada no bocal 10. (047) An additional advantage resulting from the cap screwing only occurring in the first shafts 11b of the thread 11 is that this allows the bottom part of the cap 20 to rest on the top edge of the nozzle 10, as shown in Figure 7, which guarantees the complete sealing of the package after the cap 20 is screwed on the nozzle 10 again.
(048) As Figuras 8A e 8B retratam, respectivamente, uma vista frontal e uma vista em perspectiva de uma segunda concretização do dispositivo para abertura automática de embalagens cartonadas assépticas 51 objeto da presente invenção, a qual compreende basicamente os mesmos componentes do dispositivo para abertura automática de embalagens cartonadas assépticas 1 anteriormente descrito, sendo observada apenas uma diferenciação entre seus componentes, como será visto a seguir. (048) Figures 8A and 8B show, respectively, a front view and a perspective view of a second embodiment of the device for automatic opening of aseptic carton packs 51 object of the present invention, which basically comprises the same components of the device for opening automatic aseptic carton packs 1 previously described, with only a differentiation between its components, as will be seen below.
(049) Identicamente ao dispositivo para abertura automática de embalagens cartonadas assépticas 1 anteriormente descrito, o dispositivo para abertura automática de embalagens cartonadas assépticas 51 objeto da presente concretização da invenção compreende um bocal 10, uma tampa 20 e um elemento de corte 30, em que o bocal 10 e a tampa 20 são retratados nas Figuras 8A e 8B antes de serem montados, para formar o dispositivo. (049) Similarly to the device for automatic opening of aseptic carton packs 1 described above, the device for automatic opening of aseptic carton packs 51 object of the present embodiment of the invention comprises a nozzle 10, a lid 20 and a cutting element 30, wherein the nozzle 10 and the cap 20 are pictured in Figures 8A and 8B before being assembled, to form the device.
(050) Valem para essa segunda concretização do dispositivo para abertura automática de embalagens cartonadas assépticas 51 objeto da presente invenção as mesmas observações feitas na descrição da primeira concretização da invenção em relação às diversas possibilidades de afixação do elemento de corte 30 ao bocal 10 ou ao elemento de acionamento 26 da tampa 20, o que não interfere na operação do dispositivo para abertura automática de embalagens 51 da presente concretização da invenção. (050) For this second embodiment of the device for automatic opening of aseptic carton packs 51 object of the present invention the same observations made in the description of the first embodiment of the invention in relation to the various possibilities of affixing the cutting element 30 to the nozzle 10 or to the drive element 26 of the lid 20, which does not interfere with the operation of the device for automatic opening of packages 51 of the present embodiment of the invention.
(051) Pode ser observado nas Figuras 8A e 8B que o dispositivo para abertura automática 51 compreende um bocal 10 provido de uma rosca externa 11 a qual inclui um primeiro veio 11b conectado a um segundo veio 11a de orientação oposta. A rosca 11 deve ter ao menos uma entrada, embora nas Figuras 8A e 8B ela seja representada com três entradas, o que confere mais estabilidade para o enroscamento de tampas. (051) It can be seen in Figures 8A and 8B that the automatic opening device 51 comprises a nozzle 10 provided with an external thread 11 which includes a first shaft 11b connected to a second shaft 11a of opposite orientation. Thread 11 must have at least one entry, although in Figures 8A and 8B it is represented with three entries, which gives more stability for screwing caps.
(052) A região inferior do bocal 10 é afixada a um elemento de base ou flange 12, cuja região inferior é projetada para ser afixada à camada de papel cartonado de uma embalagem cartonada asséptica por meio de colagem ou processo similar, com o bocal localizado de maneira que seu eixo de simetria seja substancialmente coincidente com o eixo de simetria do referido orifício feito na camada de papel cartonado. Como se viu anteriormente, a camada de alumínio que será rompida pelo dispositivo de abertura automática 51 se localiza logo abaixo da camada de papel cartonado. (052) The lower region of the nozzle 10 is affixed to a base element or flange 12, the lower region of which is designed to be affixed to the paperboard layer of an aseptic carton by means of gluing or similar process, with the nozzle located so that its axis of symmetry is substantially coincident with the axis of symmetry of said hole made in the layer of cardboard. As seen above, the aluminum layer that will be broken by the automatic opening device 51 is located just below the layer of cardboard.
(053) O dispositivo de abertura automática 51 compreende também uma tampa 20 provida de segmentos de rosca interna 21 os quais são projetados para serem enroscados na rosca 11 do bocal 10. A tampa 20 deve ser provida de ao menos um segmento de rosca interna 21. Na Figura são representados três segmentos de rosca interna 21, em decorrência de ser usada no bocal 10 uma rosca 11 com três entradas. (053) The automatic opening device 51 also comprises a cover 20 provided with internal thread segments 21 which are designed to be screwed into the thread 11 of the nozzle 10. The cover 20 must be provided with at least one internal thread segment 21 The figure shows three internal thread segments 21, as a thread 11 with three inlets is used in the nozzle 10.
(054) Conforme mencionado anteriormente, apenas para efeitos descritivos a presente descrição considera um dispositivo para abertura automática de embalagens cartonadas assépticas que incorpora características reveladas no documento BR 10 2019 003243 0, e como tal a tampa 30 incorpora também um elemento de acionamento 26, cuja função é descrita no referido documento BR 10 2019 003243 0, e que não será objeto de descrição no presente relatório por não ser parte do conceito inventivo da presente invenção. Consequentemente, e reiterando o que já fora anteriormente mencionado, a configuração da tampa 20 não está limitada à representação que dela se faz nas Figuras 8A e 8B. (054) As previously mentioned, for the purposes of description only, this description considers a device for automatic opening of aseptic carton packs that incorporates features revealed in document BR 10 2019 003243 0, and as such the lid 30 also incorporates a drive element 26, whose function is described in the referred document BR 10 2019 003243 0, and which will not be described in this report because it is not part of the inventive concept of the present invention. Consequently, and reiterating what has already been mentioned, the configuration of the lid 20 is not limited to the representation that is made of it in Figures 8A and 8B.
(055) O elemento de corte 30 afixado à região superior interna do bocal 10 representado nas Figuras 8A e 8B é apenas uma das diversas opções conhecidas para a configuração desse componente, tendo sido essa configuração escolhida apenas para efeitos descritivos, a qual se refere a uma das concretizações de dispositivo de abertura automática de embalagens cartonadas assépticas reveladas no referido documento BR 10 2019 003243 0, e que não será objeto de descrição no presente relatório por não ser parte do conceito inventivo da presente invenção. Consequentemente, e reiterando o que já fora anteriormente mencionado, a configuração do elemento de corte 30 não está limitada à representação que dele se faz nas Figuras 8A e 8B. (055) The cutting element 30 affixed to the upper internal region of the nozzle 10 shown in Figures 8A and 8B is only one of several options known for the configuration of this component, this configuration having been chosen only for descriptive purposes, which refers to one of the embodiments of the automatic opening device for aseptic carton packs revealed in the referred document BR 10 2019 003243 0, and which will not be described in this report because it is not part of the inventive concept of the present invention. Consequently, and reiterating what has already been mentioned, the configuration of the cutting element 30 is not limited to the representation made of it in Figures 8A and 8B.
(056) As Figuras 9 a 11 retratam etapas da operação de desenroscar pela primeira vez a tampa 30 em relação ao bocal 10 do dispositivo para abertura automática de embalagens cartonadas assépticas 51 retratado nas Figuras 8A e 8B. Para facilitar a compreensão, nas Figuras 9 a 11 foram representados apenas os segmentos de rosca interna 21 da tampa 20. Como os segmentos de rosca interna 21 são solidários à tampa 20, evidentemente, quaisquer movimentos que eles façam serão obrigatoriamente os mesmos efetuados pela tampa 20. (057) Na Figura 9 o dispositivo para abertura automática de embalagens cartonadas assépticas 51 é representado em uma situação em que seus componentes já foram devidamente montados, operação feita em fábrica. Pode ser observado na Figura 9 como os segmentos de rosca interna 21 da tampa 30 estão localizados na região posterior do segundo veio 11a da rosca 11 do bocal 10, posição em que ficam depois de a tampa 20 e o bocal 10 serem montados em fábrica para formar o dispositivo para abertura automática de embalagens cartonadas assépticas 51. Na Figura 9 somente aparece um dos segmentos de rosca interna 21 da tampa 20, pois, evidentemente, os demais estão encobertos pelo bocal 10. (056) Figures 9 to 11 depict steps in the operation of unscrewing lid 30 for the first time from the nozzle 10 of the device for automatic opening of aseptic carton packs 51 depicted in Figures 8A and 8B. In order to facilitate understanding, in Figures 9 to 11, only the internal thread segments 21 of the cover 20 are represented. As the internal thread segments 21 are attached to the cover 20, of course, any movements they make will necessarily be the same made by the cover. 20. (057) In Figure 9, the device for automatic opening of aseptic carton packs 51 is represented in a situation in which its components have already been properly assembled, an operation carried out at the factory. It can be seen in Figure 9 how the internal thread segments 21 of the cap 30 are located in the posterior region of the second shaft 11a of the thread 11 of the nozzle 10, position where they are after the cap 20 and the nozzle 10 are assembled in the factory for form the device for automatic opening of aseptic carton packs 51. In Figure 9 only one of the internal thread segments 21 of the lid 20 appears, since, of course, the others are covered by the nozzle 10.
(058) Na Figura 10 o dispositivo para abertura automática de embalagens cartonadas assépticas 1 é representado em uma situação em que já ocorreu o início do primeiro desenroscamento da tampa 20 em relação ao bocal 10, por meio da aplicação de uma rotação no sentido anti-horário à tampa 20. Consequentemente, os segmentos de rosca interna 21 da tampa 30 percorreram toda a extensão dos segundos veios 11a da rosca 11 do bocal 10, e estão localizados na junção entre os segundos veios 11a e os primeiros veios 11b da rosca 11. Como os segundos veios 11a têm orientação à esquerda, consequentemente a tampa 20 efetua um movimento axial descendente no decorrer desse percurso dos segmentos de rosca interna 21 nos segundos veios 11a da rosca 11 do bocal 10. (058) In Figure 10, the device for automatic opening of aseptic carton packs 1 is represented in a situation in which the first unscrewing of the lid 20 in relation to the nozzle 10 has already occurred, by applying a rotation in the anti- clockwise to the cap 20. Consequently, the internal thread segments 21 of the cap 30 have run the entire length of the second shafts 11a of the thread 11 of the nozzle 10, and are located at the junction between the second shafts 11a and the first shafts 11b of the thread 11. As the second shafts 11a are oriented to the left, the cap 20 consequently makes an axial downward movement along this path of the internal thread segments 21 in the second shafts 11a of the thread 11 of the nozzle 10.
(059) A composição dos movimentos de rotação e axial descendente efetuados pela tampa 20 provocaram o acionamento do elemento de corte 30, fazendo com que esse último também efetuasse uma composição de movimentos rotacional anti-horário e axial descendente. Consequentemente, nessa composição de movimentos o elemento de corte 30 efetuou o corte da camada de alumínio da embalagem, como é conhecido na técnica, por exemplo, descrito em detalhes nos documentos W02016/082008 e BR 10 2019 003243 0. Pode ser observado na Figura 10 o elemento de corte 30 já ao final de seu movimento axial descendente. (059) The composition of the rotating and descending axial movements made by the cover 20 caused the cutting element 30 to be activated, causing the latter to also perform a counterclockwise and descending axial rotational movement composition. Consequently, in this composition of movements the cutting element 30 made the cutting of the aluminum layer of the packaging, as is known in the art, for example, described in detail in documents W02016 / 082008 and BR 10 2019 003243 0. It can be seen in Figure 10 the cutting element 30 already at the end of its downward axial movement.
(060) Com a continuidade do desenroscamento da tampa 20 em relação ao bocal 10, os segmentos de rosca interna 21 passam em seguida a percorrer os primeiros veios 11b da rosca 11. Ao final desse desenroscamento da tampa 20 em relação ao bocal 10 os segmentos de rosca interna 21 saem completamente dos primeiros veios 11b da rosca 11, conforme retratado na Figura 11, e com isso a embalagem estará aberta e seu conteúdo poderá ser servido através do bocal 10. (060) With the unscrewing of the cap 20 in relation to the nozzle 10, the internal thread segments 21 then pass through the first shafts 11b of the thread 11. At the end of this unscrewing of the cap 20 in relation to the nozzle 10 the segments internal thread 21 leaves the first threads 11b of thread 11 completely, as shown in Figure 11, and with that the package will be open and its contents can be served through the nozzle 10.
(061) De acordo com os preceitos da presente invenção, em referência à sua segunda concretização, a passagem dos segmentos de rosca interna 21 da tampa 20 pelos primeiros e segundos veios 11a e 11b da rosca 11 do bocal 10 ocorre uma única vez, quando a tampa 20 for desenroscada do bocal 10 pela primeira vez, conforme descrito anteriormente. Na presente concretização os primeiros veios 11b da rosca 11 são configurados com estreitamentos 11b' os quais são formados de maneira a permitir a saída dos segmentos de rosca interna 21 da tampa 20, quando esta última for desenroscada pela primeira vez em relação ao bocal 10. Entretanto, os estreitamentos 11b' impedem que os segmentos de rosca interna 21 da tampa 20 possam entrar novamente nos primeiros veios 11b da rosca 11. Consequentemente, a tampa 20 não poderá ser novamente enroscada na rosca 11. (061) According to the precepts of the present invention, with reference to its second embodiment, the passage of the internal thread segments 21 of the cap 20 through the first and second shafts 11a and 11b of the thread 11 of the nozzle 10 occurs only once, when the cap 20 is unscrewed from the nozzle 10 for the first time, as previously described. In the present embodiment, the first shafts 11b of the thread 11 are configured with narrows 11b 'which are formed in such a way as to allow the internal thread segments 21 of the cap 20 to exit when the latter is unscrewed for the first time in relation to the nozzle 10. However, the narrowing 11b 'prevents the internal thread segments 21 of the cap 20 from being able to re-enter the first shafts 11b of the thread 11. Consequently, the cap 20 cannot be screwed back into the thread 11.
(062) Para possibilitar que a tampa 20 possa ser novamente enroscada no bocal 10, ao lado de é provido de um veio suplementar 13, paralelo ao primeiro veio 11b da rosca 11, conforme retratado nas Figuras 12, 13 e 14. Para a formação de cada veio suplementar 13 é provido um filete suplementar 13a, paralelo ao filete inferior do primeiro veio 11b, o vão compreendido entre esses dois filetes formando o referido veio suplementar 13. (062) To enable the cap 20 to be screwed back onto the nozzle 10, next to it is provided with an additional shaft 13, parallel to the first shaft 11b of the thread 11, as shown in Figures 12, 13 and 14. For the formation an additional thread 13a is provided for each additional shaft 13a, parallel to the lower thread of the first shaft 11b, the gap between these two threads forming said supplementary shaft 13.
(063) Para enroscar a tampa 20 novamente no bocal 10 ela deverá ser aposta ao bocal e em seguida ser aplicado um movimento rotacional no sentido horário, para que os segmentos de rosca interna 21 da tampa 20 possam iniciar o enroscamento no bocal 10. Como não será possível que os segmentos de rosca interna 21 da tampa 20 possam entrar nos primeiros veios 11b da rosca 11, consequentemente eles somente poderão se enroscar nos veios suplementares 13. As Figuras 12, 13 e 14 retratam toda a sequência de enroscamento, desde a entrada dos segmentos de rosca interna 21 nos veios suplementares 13, conforme retratado na Figura 12, o percurso deles pelos veios suplementares 13, conforme retratado na Figura 13, e o posicionamento final dos segmentos de rosca interna 21 da tampa 20 na região inferior dos veios suplementares 13, conforme retratado na Figura 14. (063) To screw the cap 20 onto the nozzle 10 again, it must be affixed to the nozzle and then rotate clockwise, so that the internal thread segments 21 of the cap 20 can start to screw in the nozzle 10. As it will not be possible for the internal thread segments 21 of the cap 20 to enter the first shafts 11b of the thread 11, consequently they will only be able to tangle in the additional shafts 13 Figures 12, 13 and 14 depict the entire screwing sequence, from the entry of the internal thread segments 21 into the supplementary shafts 13, as shown in Figure 12, their path through the supplementary shafts 13, as shown in Figure 13, and the final positioning of the internal thread segments 21 of the cap 20 in the lower region of the supplementary shafts 13, as shown in Figure 14.
(064) Como pôde ser observado, nesta segunda concretização da invenção a rosca 11 serve apenas para propiciar o acionamento do elemento de corte 30, para que esse possa fazer o corte da camada de alumínio da embalagem, propiciando sua abertura. Depois disso a rosca 11 não mais têm função. Consequentemente, quando a tampa 20 for novamente enroscada no bocal 10, esse enroscamento ocorrerá somente nos veios suplementares 13, de orientação à direita, e com isso os consumidores não notarão nenhuma diferença em relação ao que estão acostumados quando enroscam uma tampa em um bocal convencional. (064) As can be seen, in this second embodiment of the invention, the thread 11 only serves to trigger the cutting element 30, so that it can cut the aluminum layer of the package, allowing its opening. Thereafter thread 11 no longer has a function. Consequently, when the cap 20 is screwed back onto the nozzle 10, this screwing will only occur on the supplementary shafts 13, oriented to the right, so that consumers will not notice any difference from what they are used to when screwing a cap on a conventional nozzle. .
(065) Uma vantagem adicional decorrente de o enroscamento da tampa somente ocorrer nos veios suplementares 13 é que isso possibilita que a parte inferior do tampo da tampa 20 se assente sobre a borda superior do bocal 10, conforme retratado na Figura 14, o que garante a total vedação da embalagem depois de a tampa 20 ser novamente enroscada no bocal 10. (065) An additional advantage resulting from the cap screwing only occurring on the supplementary shafts 13 is that this allows the bottom part of the cap 20 to rest on the top edge of the nozzle 10, as shown in Figure 14, which guarantees the complete sealing of the package after the cap 20 is screwed back onto the nozzle 10.
(066) Como pôde ser observado pela descrição precedente, os dispositivos para abertura automática de embalagens cartonadas assépticas 1 e 51 objeto da presente invenção, além das evidentes vantagens decorrentes do conceito inventivo adotado, têm a grande vantagem adicional de poderem ser fabricados em moldes de injeção plástica os quais poderão ser produzidos sem dificuldades técnicas, o que reduz substancialmente os custos de fabricação. (066) As can be seen from the previous description, the devices for automatic opening of aseptic carton packs 1 and 51 object of the present invention, in addition to the evident advantages resulting from the inventive concept adopted, have the great additional advantage of being able to be manufactured in molds of plastic injection which can be produced without technical difficulties, which substantially reduces manufacturing costs.
(067) A presente invenção foi descrita em relação às suas diversas concretizações. Modificações ou substituições poderão ser introduzidas sem, no entanto, alterar o conceito inventivo descrito e revelado neste relatório. Assim, a presente invenção não está limitada às concretizações descritas, estando apenas limitada ao conteúdo das reivindicações que acompanham o presente relatório. (067) The present invention has been described in relation to its various embodiments.
