Description

"DISPOSIÇÃO CONSTRUTIVA PARA ABERTURA DE EMBALAGENS CARTONADAS" Campo da inovação "CONSTRUCTIVE ARRANGEMENT FOR OPENING CARTON PACKAGES" Field of innovation
[ 001 ] Refere-se a presente inovação, na natureza de modelo de utilidade, a uma disposição construtiva aplicada a embalagens cartonadas do tipo utilizado para conter produtos alimentícios liquidos, de consumo progressivo, tais como leite, sucos, achocolatados e outros, sendo referidas embalagens geralmente em forma de "caixa" paralelepipédica, apresentando seção transversal horizontal quadrada, seção transversal vertical retangular alongada e uma parede extrema superior provida de um bocal que é normalmente fechado por um lacre, manualmente rompivel quando da primeira abertura da embalagem, e por uma tampa que pode ser do tipo roscada no bocal ou nele encaixada, para que o usuário possa abrir e fechar a embalagem múltiplas vezes, durante a liberação de determinadas quantidades parciais do produto liquido armazenado na embalagem. [001] This innovation refers, in the nature of a utility model, to a constructive arrangement applied to carton packaging of the type used to contain liquid food products, for progressive consumption, such as milk, juices, chocolate drinks and others, being referred to packages generally in the shape of a parallelepiped "box", with a square horizontal cross-section, an elongated rectangular vertical cross-section and an upper extreme wall provided with a mouthpiece that is normally closed by a seal, which can be manually broken when the package is first opened, and by a cap that can be screwed onto the nozzle or fitted into it, so that the user can open and close the packaging multiple times, during the release of certain partial quantities of the liquid product stored in the packaging.
Antecedentes da inovação Background of innovation
[ 002 ] São bem conhecidas do estado da técnica as embalagens cartonadas paralelepipédicas do tipo acima mencionado, tendo sua parede extrema superior incorporando, junto à região mediana de uma de suas arestas ou junto a um dos vértices formados por duas arestas, um único bocal vertedor, provido de um lacre rompivel pelo usuário e, cobrindo o lacre, uma tampa que pode ser do tipo roscada em uma projeção tubular do bocal vertedor ou do tipo articulada ao bocal vertedor e deslocável entre uma posição fechada, encaixada no bocal, e uma posição aberta, deslocada angularmente para cima e para o lado do bocal vertedor . [ 003 ] Essas embalagens cartonadas são feitas em camadas sobrepostas, geralmente laminadas, de papelão, plástico e aluminio, sendo geralmente usada pelo menos uma camada interna de polimero, como o polietileno, uma camada intermediária de aluminio, uma camada estrutural de papel cartonado ou papelão e pelo menos uma camada externa de polimero, geralmente o polietileno . [002] Parallelepiped carton packages of the aforementioned type are well known in the art, with their upper extreme wall incorporating, next to the median region of one of its edges or next to one of the vertices formed by two edges, a single pouring nozzle , provided with a seal that can be broken by the user and, covering the seal, a lid that can be of the threaded type on a tubular projection of the pouring nozzle or of the type articulated to the pouring nozzle and movable between a closed position, fitted to the nozzle, and a position open, displaced angularly upwards and to the side of the pouring nozzle. [003] These carton packages are made in overlapping layers, generally laminated, of cardboard, plastic and aluminum, with at least one internal layer of polymer being generally used, such as polyethylene, an intermediate layer of aluminum, a structural layer of cardboard paper or cardboard and at least one outer layer of polymer, generally polyethylene.
[ 004 ] Nesse tipo de embalagem, o bocal vertedor único é posicionado junto à região mediana de uma das arestas ou junto a um dos vértices da parede superior, para que o usuário possa, após o rompimento do lacre de inviolabilidade, abrir o bocal vertedor, desenroscando ou levantando a tampa, e inclinar a embalagem, de modo a permitir que o produto liquido seja vazado na quantidade desejada . O derrame do produto liquido é interrompido com o retorno da embalagem a uma posição vertical ou aproximadamente vertical, quando a tampa pode ser rosqueada ou encaixada no bocal vertedor, fechando a embalagem de modo a preservar o restante produto nela contido . [004] In this type of packaging, the single pouring nozzle is positioned close to the median region of one of the edges or close to one of the vertices of the upper wall, so that the user can, after breaking the tamper-evident seal, open the pouring nozzle , unscrewing or lifting the lid, and tilting the packaging to allow the liquid product to be poured in the desired quantity. The pouring of the liquid product is stopped by returning the packaging to a vertical or approximately vertical position, when the lid can be screwed or fitted onto the pouring nozzle, closing the packaging in order to preserve the remaining product contained therein.
[ 005 ] Ocorre que nessas embalagens, a seção transversal da abertura definida no bocal vertedor único e seu posicionamento na parede superior da embalagem dificultam ou mesmo impedem a entrada de ar na embalagem durante a operação de derrame do produto, impedindo que o referido derrame ocorra por fluxo laminar do produto liquido, particularmente nas condições nas quais a embalagem contém uma grande quantidade do produto liquido . Nessa situação, é bastante comum que o derrame do produto ocorra por bateladas, dificultando o controle do fluxo por parte do usuário e causando, frequentemente, pequenos desastres por derrame de líquido para fora do recipiente utilizado para receber o produto sendo retirado da embalagem. [005] It happens that in these packages, the cross-section of the opening defined in the single pouring nozzle and its positioning on the upper wall of the package make it difficult or even prevent the entry of air into the package during the product pouring operation, preventing said spill from occurring. by laminar flow of the liquid product, particularly under conditions in which the packaging contains a large amount of the liquid product. In this situation, it is quite common for the product to spill in batches, making it difficult for the user to control the flow and often causing small disasters due to spillage. liquid out of the container used to receive the product being removed from the packaging.
[ 006] As embalagens cartonadas do tipo aqui considerado, apresentam, portanto, o inconveniente de dificultar a liberação do conteúdo líquido, por meio de um fluxo laminar controlável pelo usuário, tornando essa operação desconfortável e levando, muitas vezes, a um derrame de líquido para fora do recipiente utilizado para receber o produto extraído da embalagem. Sumário da inovação [006] Carton packaging of the type considered here therefore has the inconvenience of making it difficult to release the liquid content, through a laminar flow controllable by the user, making this operation uncomfortable and often leading to a liquid spill. out of the container used to receive the product extracted from the packaging. Innovation summary
[ 007 ] Em razão do inconveniente acima mencionado e relacionado à técnica anterior, é um objetivo da presente inovação prover uma disposição construtiva para abertura de embalagens cartonadas providas do usual bocal vertedor superior, fechado por um lacre rompível e por uma tampa a ser aberta e fechada múltiplas vezes durante o consumo parcial e progressivo do produto embalado, sendo a referida disposição construtiva configurada para permitir que o conteúdo líquido da embalagem possa ser fácil e controladamente vazado em fluxo laminar . [007] Due to the inconvenience mentioned above and related to the prior art, it is an objective of the present innovation to provide a constructive arrangement for opening carton packages provided with the usual upper pouring nozzle, closed by a breakable seal and by a lid to be opened and closed multiple times during the partial and progressive consumption of the packaged product, said constructive arrangement being configured to allow the liquid content of the package to be easily and controlledly poured out in laminar flow.

The pouring nozzle 60 of figures 1, 2 and 3 also comprises a seal 64, breakable and which can be defined in different constructive solutions, one of which is defined by respective overlapping portions of the intermediate layer 30 of aluminum and the internal layer 20 of polymer. , portions of which have the same contour as the opening A of the carton packaging 10 , to keep it closed by seal 64, until the first pouring operation of the packaged product is carried out.
[ 0019] Na configuração ilustrada nas figuras 4 , 5 e 6, o bocal vertedor 70 compreende um flange anelar 71 , de formato oblongo e hermeticamente fixado nas camadas estrutural 40 e na camada externa 50 de polimero, em torno de uma abertura A provida em referidas camadas, sendo que ao flange anelar oblongo 71 é articuladamente incorporada uma tampa 73 que pode ser deslocada angularmente, entre uma posição fechada e encaixada no flange anelar 71 e uma posição aberta deslocada para cima e para um lado . O bocal vertedor 70 das figuras 4 e 5, compreende ainda um lacre 74 , rompivel e que é geralmente definido por respectivas porções sobrepostas da camada intermediária 30 de aluminio e da camada interna 20 de polimero, porções essas apresentando o mesmo contorno da abertura A da embalagem cartonada 10 , para mantê-la fechada pelo lacre 74 , até a realização da primeira operação de vazamento do produto embalado . [0019] In the configuration illustrated in figures 4, 5 and 6, the pouring nozzle 70 comprises an annular flange 71, oblong in shape and hermetically fixed to the structural layers 40 and the external polymer layer 50, around an opening A provided in said layers, with the oblong annular flange 71 being pivotably incorporated with a cover 73 that can be angularly displaced, between a closed position and fitted into the annular flange 71 and an open position displaced upwards and to one side. The pouring nozzle 70 of figures 4 and 5 also comprises a breakable seal 74, which is generally defined by respective overlapping portions of the intermediate aluminum layer 30 and the internal polymer layer 20, these portions having the same contour as the opening A of the carton packaging 10, to keep it closed by the seal 74, until the first pouring operation of the packaged product is carried out.
[ 0020 ] Por ocasião do consumo do produto liquido contido na embalagem cartonada 10 , o consumidor retira, por giro, a tampa roscada 63 da projeção tubular 62 do bocal vertedor 60 , produzindo o rompimento do lacre 64 e a liberação do produto pela inclinação da embalagem cartonada 10 ilustrada nas figuras 1 , 2 e 3 . [0020] When consuming the liquid product contained in the carton packaging 10, the consumer removes, by turning, the screw cap 63 from the tubular projection 62 of the pouring nozzle 60, causing the seal 64 to break and the product to be released by tilting the carton packaging 10 illustrated in figures 1, 2 and 3.
[ 0021 ] Por ocasião do consumo do produto liquido contido na embalagem ilustrada nas figuras 4 e 5, o consumidor levanta a tampa 73, deslocando-a angularmente para cima, em torno de sua articulação ao flange anelar 71 , de formato oblongo, liberando o acesso manual do usuário ao lacre 74 que pode ser então manualmente retirado, para permitir o vazamento do produto pela inclinação da embalagem cartonada 10 . [0021] When consuming the liquid product contained in the packaging illustrated in figures 4 and 5, the consumer lifts the lid 73, moving it angularly upwards, around its articulation with the oblong-shaped annular flange 71, releasing the manual user access to the seal 74 which can then be manually removed to allow product leakage due to the tilt of the carton packaging 10 .
[ 0022 ] De acordo com a inovação, a parede superior 11 da embalagem cartonada 10 é provida ainda de um bocal aerador 60a, 70a, com construção igual ou semelhante ao do bocal vertedor 60 , 70 já usualmente provido em referidas embalagens cartonadas 10 . Caso os bocais, vertedor 60 , 70 e aerador 60a, 70a, apresentem a mesma construção, com capacidade vertedora, eles poderão ser utilizados alternadamente, para vazamento do produto ou para ventilação, dando mais versatilidade ao usuário sobre o posicionamento a ser escolhido para a inclinação da embalagem cartonada 10 durante o vazamento do produto . [0022] According to the innovation, the upper wall 11 of the carton packaging 10 is also provided with an aerator nozzle 60a, 70a, with the same or similar construction as the pouring nozzle 60, 70 already usually provided in said carton packagings 10. If the nozzles, pourer 60, 70 and aerator 60a, 70a, have the same construction, with pouring capacity, they can be used alternately, for pouring the product or for ventilation, giving the user more versatility regarding the positioning to be chosen for the tilting of the carton packaging 10 during pouring of the product.
[ 0023 ] Deve ser entendido que o bocal aerador 60a, 70a é construído preferivelmente de acordo com as mesmas características do bocal vertedor 60 , 70 , podendo haver, opcionalmente, apenas variação dimensional para definir a seção transversal mais adequada às funções vertedora e aeradora . Assim o bocal aerador 60a, 70a apresenta os mesmos elementos já definidos para o bocal vertedor 60 , 70 , elementos esses que recebem os mesmos números de referência nas figuras de desenho, acompanhados da letra "a", com flange anelar 61a, 71a, projeção tubular 62a, tampa 63a, 73a e lacre 64a, 74a . [0023] It should be understood that the aerator nozzle 60a, 70a is preferably built according to the same characteristics as the pouring nozzle 60, 70, and there may be, optionally, only dimensional variation to define the cross section most suitable for the pouring and aerating functions. Thus, the aerator nozzle 60a, 70a presents the same elements already defined for the pouring nozzle 60, 70, these elements receiving the same reference numbers in the drawing figures, accompanied by the letter "a", with an annular flange 61a, 71a, projection tubular 62a, lid 63a, 73a and seal 64a, 74a.
[ 0024 ] Como pode ser observado pelas figuras, o bocal vertedor 60 , 70 e o bocal aerador 60a, 70a são posicionados de modo excêntrico na parede superior 11 da embalagem cartonada 10, podendo ser respectivamente dispostos próximo a vértices diagonalmente opostos da parede superior 11 da embalagem cartonada 10 , conforme ilustrado nas figuras 3, 4 , 5 e 6, ou serem dispostas próximo às bordas frontal e posterior, respectivamente, da parede superior 11 da embalagem cartonada 10, conforme ilustrado nas figuras 1 e 2 . Em ambos os casos, os dois bocais são excêntricos e posicionados distanciados entre si e em lados da parede superior 11 opostos em relação ao centro dessa última, como ilustrado nas figuras dos desenhos anexos . [0024] As can be seen from the figures, the pouring nozzle 60, 70 and the aeration nozzle 60a, 70a are positioned eccentrically on the upper wall 11 of the carton packaging 10, and can be respectively arranged close to diagonally opposite vertices of the upper wall 11 of the carton packaging 10, as illustrated in figures 3, 4, 5 and 6, or be arranged close to the front and back edges, respectively, from the upper wall 11 of the carton package 10, as illustrated in figures 1 and 2. In both cases, the two nozzles are eccentric and positioned at a distance from each other and on opposite sides of the upper wall 11 in relation to the center of the latter, as illustrated in the figures in the attached drawings.
[ 0025 ] Com o arranjo construtivo proposto, o usuário destaca a tampa 63, 73, 63a, 73a dos respectivos bocais vertedor e aerador, e rompe os respectivos lacres 64 , 74 , 64a, 74a para liberar a primeira operação de vazamento do produto pelo bocal vertedor 60 , 70 , enquanto o bocal aerador 60a, 70a passa a operar como abertura de ventilação, permitindo que o conteúdo liquido da embalagem possa ser fácil e cont roladamente vazado em fluxo laminar . [0025] With the proposed constructive arrangement, the user detaches the lid 63, 73, 63a, 73a from the respective pouring and aerator nozzles, and breaks the respective seals 64, 74, 64a, 74a to release the first pouring operation of the product through the pouring nozzle 60, 70, while the aerator nozzle 60a, 70a starts to operate as a ventilation opening, allowing the liquid contents of the packaging to be easily and controlledly poured out in laminar flow.
