Description

"ARRANJO CONSTRUTIVO PARA ABERTURA DE EMBALAGENS CARTONADAS" Campo da invenção "CONSTRUCTIVE ARRANGEMENT FOR OPENING CARTON PACKAGES" Field of invention
[ 001 ] Refere-se a presente invenção a um arran j o construtivo aplicado a embalagens cartonadas do tipo utilizado para conter pequenas quantidades de produtos alimentícios liquidos , tais como sucos , achocolatados e outros , tendo referidas embalagens geralmente a forma de uma "caixinha" paralelepipédica provida, em uma parede extrema superior, de uma abertura circular, normalmente fechada por um painel rompivel e que é rompido quando pres sionado por um extremo chanfrado de um canudo configurado para ser inserido, pelo usuário e de modo justo, no interior da embalagem cartonada e , as sim, permitir que o produto liquido pos sa ser succionado pelo consumidor . [ 001 ] The present invention refers to a constructive arrangement applied to carton packages of the type used to contain small amounts of liquid food products, such as juices, chocolate drinks and others, said packages generally having the shape of a parallelepiped "box" provided, in an upper end wall, with a circular opening, normally closed by a tear-off panel and which is ruptured when pressed by a chamfered end of a straw configured to be inserted, by the user and snugly, inside the carton pack and, thus, allow the liquid product to be sucked by the consumer.
Antecedentes da invenção Background of the invention
[ 002 ] São bem conhecidas do estado da técnica as embalagens cartonadas paralelepipédicas , com parede extrema superior provida de uma abertura circular que é fechada por um painel a ser rompido por meio da inserção de um usual canudo, em material normalmente reciclável , utilizado para sucção do produto liquido por parte do consumidor . [ 002 ] Parallelepipedic carton packs are well known in the state of the art , with an upper extreme wall provided with a circular opening that is closed by a panel to be broken through the insertion of a usual straw , in normally recyclable material , used for suction of the liquid product by the consumer.
[ 003 ] Es sas 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 . [ 003 ] These carton packs are made in superimposed layers, usually laminated, of cardboard, plastic and aluminum, generally using at least one inner layer of polymer, such as polyethylene, an intermediate layer of aluminum, a structural layer of cardboard or paperboard and at least one outer layer of polymer, usually polyethylene.
[ 004 ] Nes se tipo de embalagem, a abertura circular para a introdução do canudo de sucção é definida na pelo menos uma camada externa de polímero e na camada estrutural de papel cartonado, sendo que a referida abertura circular permanece fechada por um painel rompível, definido por respectivas porções da camada intermediária de alumínio e pela pelo menos uma camada interna de polímero, garantindo a estanqueidade da embalagem até que o referido painel rompível se j a rompido pelo consumidor, por meio do pres sionamento do extremo chanfrado do canudo ( ou de outro instrumento qualquer ) sobre a camada intermediária de alumínio e sobre a pelo menos uma camada interna de polímero . [ 004 ] In this type of packaging, the circular opening for inserting the suction straw is defined in at least one outer layer of polymer and the structural layer of cardboard paper, said circular opening remaining closed by a breakable panel, defined by respective portions of the intermediate layer of aluminum and the at least one inner layer of polymer, ensuring the tightness of the package up to that said breakable panel is already broken by the consumer, by means of pressing the chamfered end of the straw (or any other instrument) on the intermediate layer of aluminum and on the at least one internal layer of polymer.
[ 005 ] Com o rompimento do painel , formado por respectivas porções da camada intermediária de alumínio e de pelo menos uma camada interna de polímero, o consumidor pode introduzir o canudo no interior da embalagem e iniciar a sucção do conteúdo líquido . [ 005 ] With the rupture of the panel , formed by respective portions of the intermediate layer of aluminum and at least one inner layer of polymer , the consumer can introduce the straw inside the package and start suctioning the liquid content .
[ 00 6 ] Ocorre que nes sas embalagens , o diâmetro da abertura circular, provida em pelo menos uma camada externa de polímero e na camada estrutural de papel cartonado ou papelão, corresponde , com pequena ou quase nenhuma folga, ao diâmetro externo do canudo, dificultando ou mesmo impedindo a entrada de ar na embalagem, durante a sucção do produto líquido pelo consumidor ou ainda o derrame inadvert ido do líquido pela abertura circular na qual o canudo está inserido . [ 00 6 ] It happens that in these packages, the diameter of the circular opening, provided in at least one external layer of polymer and in the structural layer of cardboard or cardboard, corresponds, with little or almost no gap, to the external diameter of the straw, making it difficult or even preventing the entry of air into the package, during the suction of the liquid product by the consumer or even the inadvertent spillage of the liquid through the circular opening in which the straw is inserted.
[ 007 ] O inconveniente des se conhecido arran j o construtivo para a abertura das pequenas embalagens cartonadas para produtos alimentícios líquidos , resulta do fato delas dificultarem a sucção progres siva de seu conteúdo líquido, a ponto de provocar o colapso estrutural-volumétrico da embalagem, para compensar o desequilíbrio das pres sões interna e atmos férica, a medida que o conteúdo liquido vai sendo succionado, com certa intensidade , o que ocorre geralmente com adultos . Es sa operação é desconfortável , exigindo es forço de sucção para a retirada completa do conteúdo da embalagem . [ 007 ] The inconvenience of this well-known constructive arrangement for opening small carton packages for liquid food products results from the fact that they make the progressive suction of their liquid content difficult, to the point of causing the structural-volumetric collapse of the package, to compensate for pressure imbalance internal and atmospheric, as the liquid content is sucked in, with certain intensity, which generally occurs with adults. This operation is uncomfortable, requiring suction effort for complete removal of the contents of the package.
[ 008 ] O inconveniente acima é ainda mais acentuado quando o conteúdo liquido da embalagem é succionado por uma criança . Nesse caso, é mais dificil ocorrer um intenso colapso volumétrico da embalagem por falta de pres são negat iva de sucção, levando o consumidor infantil a interromper o proces so de sucção do liquido antes de extraido todo o conteúdo da embalagem . [ 008 ] The above inconvenience is even more pronounced when the liquid content of the package is sucked by a child . In this case, it is more difficult for an intense volumetric collapse of the package to occur due to lack of negative suction pressure, leading the child consumer to interrupt the process of sucking the liquid before extracting the entire contents of the package.
[ 00 9 ] As embalagens cartonadas do tipo aqui considerado, apresentam, portanto, o inconveniente de dificultar a sucção do conteúdo liquido, tornando es sa operação desconfortável , particularmente para as crianças e levando, muitas vezes , a uma extração incompleta do produto liquido do interior da embalagem . [ 00 9 ] Carton packs of the type considered here, therefore, have the inconvenience of making it difficult to suck out the liquid content, making this operation uncomfortable, particularly for children and often leading to an incomplete extraction of the liquid product from the inside the package.
[ 0010 ] Outro inconveniente das embalagens cartonadas aqui consideradas resulta do fato de o pres sionamento do extremo chanfrado do canudo ( ou de outro instrumento qualquer ) sobre o painel rompivel, definido pela camada intermediária de aluminio e por pelo menos uma camada interna de polimero, provoca não só o rompimento do painel rompivel , mas ainda seu deslocamento para o interior da embalagem, levando impurezas e eventuais agentes patogênicos , depositados sobre a painel rompivel durante o periodo de prateleira da embalagem cartonada 10 , a contatarem o produto alimentício armazenado e a ser succionado pelo consumidor, usualmente uma criança . Sumário da invenção [ 0011 ] Em razão dos inconvenientes acima mencionados e relacionados à técnica anterior, é um ob j etivo da presente invenção prover um arran j o construtivo para abertura de embalagens cartonadas para conter quantidades individuais de produtos alimentícios liquidos succionáveis , pelo consumidor, por um canudo a ser inserido, de modo justo, através de uma abertura circular superior da embalagem, sendo o referido arran j o construtivo configurado para permitir que o conteúdo liquido das embalagens pos sa ser fácil e completamente succionado, sem exigir inadequados es forções de sucção, sem provocar deformação estrutural volumétrica das embalagens e sem tornar as embalagens susceptíveis a indese j áveis derrames do liquido, durante as operações de consumo do produto embalado . [ 0010 ] Another drawback of the carton packages considered here results from the fact that pressing the chamfered end of the straw (or any other instrument) on the breakable panel, defined by the intermediate layer of aluminum and at least one internal layer of polymer, causes not only the rupture of the breakable panel, but also its displacement towards the inside of the package, taking impurities and eventual pathogenic agents, deposited on the breakable panel during the shelf period of the carton package 10 , to contact the stored food product and to be sucked by the consumer, usually a child. Summary of the invention [0011] Due to the aforementioned drawbacks and related to the prior art, it is an object of the present invention to provide a constructive arrangement for opening carton packages to contain individual quantities of liquid food products suckable, by the consumer, through a straw to be inserted, in a tight manner, through an upper circular opening of the package, said constructive arrangement being configured to allow the liquid content of the packages to be easily and completely sucked, without requiring inadequate suction efforts, without causing deformation volumetric structure of the packaging and without making the packaging susceptible to undesirable spills of liquid, during operations of consumption of the packaged product.

[ 0022 ] The first and second openings 12, 13 are defined by at least one outer layer 50 of polymer, the structural layer 40 of paperboard, the intermediate layer 30 of aluminum and at least one inner layer 20 of polymer, communicating the inside of the carton pack 10 with the outside, through the upper wall 11.
[ 0023 ] A primeira e a segunda aberturas 12 , 13 são mantidas externamente fechadas , cada uma, por um lacre L de estanqueidade , definido por uma película 60 , de plástico ou de outro material adequado, como alumínio, sendo a película 60 de cada lacre L dimensionada para ser colada, de modo manualmente destacável , diretamente , ou sobre uma base pré incorporada na embalagem, na face externa da parede superior 11 da embalagem cartonada 10, em torno da respectiva abertura[0023] The first and second openings 12, 13 are kept externally closed, each one by a sealing seal L, defined by a film 60, of plastic or other suitable material, such as aluminum, the film 60 of each L-seal sized to be glued, manually detachable, directly, or on a pre-incorporated base in the package, on the external face of the upper wall 11 of the carton pack 10, around its opening
12, 13. 12, 13.
[0024] Cada película 60 incorpora, em um dos extremos e preferivelmente em peça única, uma porção de pega 61, que se estende para fora da região da respectiva abertura 12, 13 e que permanece não-colada na parede superior 11, para poder ser mantida assentada sobre essa última ou dobrada sobre parte da extensão da película 60, para poder ser deslocada para cima e pega pelos dedos do consumidor que, então, poderá puxar o lacre L, destacando-o da parede superior 11 e abrindo superiormente cada abertura 12, 13 para fora da embalagem 10, conforme ilustrado nas figuras 1, 5 e 6. [0024] Each film 60 incorporates, at one end and preferably in a single piece, a handle portion 61, which extends outside the region of the respective opening 12, 13 and which remains unglued on the upper wall 11, in order to be able to be kept seated on the latter or folded over part of the length of the film 60, so that it can be moved upwards and taken by the consumer's fingers, who will then be able to pull the seal L, detaching it from the upper wall 11 and opening each opening at the top 12, 13 out of the package 10, as shown in figures 1, 5 and 6.
[0025] Enquanto os lacres L estiverem colados sobre a face externa da parede superior 11 da embalagem cartonada 10, essa última estará hermeticamente fechada, mantendo o produto embalado protegido de contaminação. [0025] While the seals L are glued on the outer face of the upper wall 11 of the carton package 10, the latter will be hermetically closed, keeping the packaged product protected from contamination.
[0026] Ainda de acordo com a invenção, cada uma das, primeira e segunda, aberturas 12, 13 da parede superior 11 é associada a uma respectiva válvula de retenção VR definida em uma placa 70 de polímero, por exemplo polietileno, compatível com o armazenamento de produtos alimentícios e tendo um contorno, poligonal ou circular. A placa 70 tem uma porção anelar periférica 71 incorporada à face interna da parede superior 11, em torno de uma respectiva abertura 12, 13, e uma porção central 72 definida por uma pluralidade de setores S, circunf erencialmente adjacentes e separados entre si apenas por recortes radiais 73 providos em referida porção central 72, sendo os setores S elasticamente deformáveis de uma condição de repouso, coplanares entre si e fechando a válvula de retenção VR, para uma condição de abertura da válvula de retenção VR, na qual são flexionados para o interior da embalagem cartonada 10, por ação de um canudo 80 inserido na embalagem 10 ou por queda de pressão no interior dessa última . [0026] Still according to the invention, each of the first and second openings 12, 13 of the upper wall 11 is associated with a respective check valve VR defined in a polymer plate 70, for example polyethylene, compatible with the storage of food products and having an outline, polygonal or circular. The plate 70 has a peripheral ring portion 71 incorporated into the inner face of the upper wall 11, around a respective opening 12, 13, and a central portion 72 defined by a plurality of sectors S, circumferentially adjacent and separated from each other only by radial cutouts 73 provided in said central portion 72, sectors S being elastically deformable from a rest condition, coplanar to each other and closing the check valve VR, to an opening condition of the check valve VR retention, in which they are flexed towards the inside of the carton pack 10, by the action of a straw 80 inserted in the pack 10 or by pressure drop inside the latter.
[0027] Cada placa 70 tem sua porção central 72, geralmente circular e cujo contorno 72a define, com o contorno da placa 70, a porção anelar periférica 71 que é colada ou de outro modo incorporada à face interna da parede superior 11 da embalagem cartonada 10, em torno da respectiva primeira ou segunda abertura 12, 13, sendo a porção central 72 de cada placa 70 provida de recortes radiais 73, geralmente em número de oito, igualmente espaçados e que se estendem desde o contorno 72a da porção central 72 até o centro 72b dessa última, em alinhamento axial com o centro das respectivas primeira e segunda aberturas 12, 13 da parede superior 11. [0027] Each plate 70 has its central portion 72, generally circular and whose contour 72a defines, with the contour of the plate 70, the peripheral ring portion 71 which is glued or otherwise incorporated into the inner face of the upper wall 11 of the carton pack 10, around the respective first or second opening 12, 13, the central portion 72 of each plate 70 being provided with radial cutouts 73, generally eight in number, equally spaced and extending from the contour 72a of the central portion 72 to the center 72b of the latter, in axial alignment with the center of the respective first and second openings 12, 13 of the upper wall 11.
[0028] A construção acima descrita permite que a porção central 72 de cada placa 70 seja definida por uma pluralidade de setores S circunf erencialmente adjacentes e que podem ser elast icamente deformados de uma condição de repouso ou de válvula de retenção VR fechada, ilustrada nas figuras 3, 4 e[0028] The construction described above allows the central portion 72 of each plate 70 to be defined by a plurality of sectors S circumferentially adjacent and which can be elastically deformed from a condition of rest or closed check valve VR, illustrated in the figures 3, 4 and
5, na qual permanecem coplanares e adjacentes entre si, mantendo a porção central 72 fechada, para uma condição flexionada para o interior da embalagem cartonada 10, por ação do usual canudo 80 (fornecido com essas embalagens) , como ilustrado nas figuras 5 e 6, ou por queda de pressão no interior da embalagem cartonada 10, como ilustrado na figura5, in which they remain coplanar and adjacent to each other, keeping the central portion 72 closed, for a condition flexed towards the inside of the carton package 10, by the action of the usual straw 80 (supplied with these packages), as illustrated in figures 5 and 6 , or by pressure drop inside the carton package 10, as illustrated in figure
6, e na qual permitem a passagem do canudo 80, primeiramente de seu extremo chanfrado 81, por uma das primeira e segunda aberturas 12, 13 e a entrada de ar através da outra de ditas aberturas 12, 13, para equilíbrio da pressão interna da embalagem cartonada 10 com a pressão atmosférica, durante a sucção do produto pelo consumidor. 6, and in which they allow the passage of the straw 80, firstly from its chamfered end 81, through one of the first and second openings 12, 13 and the entry of air through the other of said openings 12, 13, for balancing the internal pressure of the carton package 10 with atmospheric pressure, during the suction of the product by the consumer.
[0029] A primeira abertura 12, circular, das embalagens cartonadas em questão, apresenta um diâmetro que corresponde, com pouca ou quase nenhuma folga, ao diâmetro do canudo 80, de tal modo que, quando esse último é encaixado através da primeira abertura 12, fica praticamente bloqueada a passagem de ar entre o canudo 80 e o contorno da referida abertura 12. [0030] O material e as dimensões da placa 70 são determinados para que os setores S permaneçam em uma condição de repouso, coplanares e adjacentes entre si, mantendo fechada a porção central 72 e impedindo que borrifos e respingos do liquido embalado sejam expelidos para fora da embalagem cartonada 10 por aquela primeira ou segunda abertura 12, 13 que não esteja recebendo um canudo 80. [0029] The first opening 12, circular, of the carton packs in question, has a diameter that corresponds, with little or almost no clearance, to the diameter of the straw 80, in such a way that, when the latter is fitted through the first opening 12 , the passage of air between the straw 80 and the contour of said opening 12 is practically blocked. [0030] The material and dimensions of the plate 70 are determined so that the sectors S remain in a condition of rest, coplanar and adjacent to each other , keeping the central portion 72 closed and preventing splashes and splashes of the packaged liquid from being expelled out of the carton package 10 through that first or second opening 12, 13 that is not receiving a straw 80.
[0031] A condição de fechamento da porção central 72 e, consequentemente, da válvula de retenção VR, é mantida enquanto os referidos setores S não estiverem submetidos a alguma força que os faça fletir elasticamente, em direção ao interior da embalagem cartonada 10, para uma condição na qual se afastam entre si, desbloqueando a porção central 72 e levando a válvula de retenção VR à condição aberta, conforme ilustrado na figura 6. As forças capazes de deformar elasticamente os setores S são definidas pela introdução do canudo 80 (ver figuras 5 e 6) e/ou por uma queda de pressão interna da embalagem cartonada 10 (ver figura 6) , como consequência de um esforço de sucção de produto, pelo canudo 80, por parte do consumidor. [0031] The closing condition of the central portion 72 and, consequently, of the check valve VR, is maintained as long as said sectors S are not subjected to any force that makes them flex elastically, towards the inside of the carton package 10, to a condition in which they move away from each other, unlocking the central portion 72 and bringing the check valve VR to the open condition, as illustrated in figure 6. The forces capable of elastically deforming the sectors S are defined by the introduction of the straw 80 (see figures 5 and 6) and/or by a drop in internal pressure of the carton package 10 (see figure 6), as a result of an effort to suck the product, through the straw 80, on the part of the consumer.
[0032] Por ocasião do consumo do produto liquido contido na embalagem 10, o consumidor não necessita furar o painel rompível das embalagens conhecidas e empurrá-lo para o interior da embalagem cartonada 10 , mas apenas puxar as porções de pega 61 dos lacres L, destacando-os de sobre as , primeira e segunda, aberturas 12 , 13 e , em seguida, escolher a abertura na qual deverá inserir uma porção da extensão do canudo 80 no interior da embalagem cartonada 10 , forçando os setores S da respectiva válvula de retenção VR a fletirem para o interior da embalagem cartonada 10 , conforme ilustrado nas figuras 5 e 6 , para permitir que o consumidor succione o liquido embalado . [0032] When consuming the liquid product contained in package 10, the consumer does not need to drill the panel breakable part of the known packages and push it into the carton package 10, but only pull the handle portions 61 of the seals L, detaching them from the first and second openings 12, 13 and then choosing the opening in which a portion of the extension of the straw 80 must be inserted inside the carton pack 10 , forcing the sectors S of the respective check valve VR to bend towards the inside of the carton pack 10 , as shown in figures 5 and 6 , to allow the consumer sucks the packaged liquid.
[ 0033 ] Quando a sucção de liquido, promovida pelo consumidor, produzir uma redução de pres são no interior da embalagem, o diferencial de pres são, em relação à pres são atmos férica, provocará a flexão, por deformação elástica, dos setores S da porção central 72 da válvula de retenção VR daquela abertura 13 desprovida do canudo 80 , afastando os setores S entre si e conduzindo a válvula de retenção VR a uma condição aberta, para permitir a entrada de ar no interior da embalagem cartonada 10 e o reequilibrio de sua pres são interna com a pres são atmos férica, permitindo que o consumidor pos sa succionar todo o produto liquido pelo extremo externo 82 do canudo 80 , facilmente e sem grandes esforços . [ 0033 ] When the suction of liquid, promoted by the consumer, produces a pressure reduction inside the package, the pressure differential, in relation to the atmospheric pressure, will cause the bending, by elastic deformation, of the S sectors of the central portion 72 of the check valve VR of that opening 13 devoid of the straw 80, moving the sectors S apart from each other and leading the check valve VR to an open condition, to allow the entry of air inside the carton package 10 and the rebalancing of its internal pressure with atmospheric pressure, allowing the consumer to suck all the liquid product through the external end 82 of the straw 80, easily and without great efforts.
[ 0034 ] Nos casos em que a primeira e a segunda aberturas 12 , 13 apresentam o mesmo contorno e a mesma dimensão, elas poderão ser utilizadas alternadamente para inserção do canudo 80 ou para ventilação, dando mais versatilidade ao usuário sobre o posicionamento a ser escolhido para inserção do canudo 80 de sucção, após terem sido os respectivos lacres L destacados da parede superior 11 da embalagem cartonada 10 . [ 0035 ] Como pode ser observado pelas figuras , a primeira abertura 12 e a segunda abertura 13 são posicionadas de modo excêntrico na parede superior 11 da embalagem cartonada 10 , podendo ser respectivamente dispostas próximo a vértices diagonalmente opostos da parede superior 11 da embalagem cartonada 10 , conforme ilustrado na figura 1 , ou serem transversalmente opostas , dispostas próximo às bordas frontal e posterior, respectivamente , da parede superior 11 da embalagem cartonada 10 , conforme ilustrado na figura 2 . Em ambos os casos , as duas aberturas 12 , 13 são excênt ricas e posicionadas distanciadas entre si e em lados da parede superior 11 opostos em relação ao centro des sa última, como ilustrado nas figuras 1 e 2 dos desenhos anexos . [ 0034 ] In cases where the first and second openings 12 , 13 have the same contour and the same dimension, they can be used alternately for inserting the straw 80 or for ventilation, giving the user more versatility regarding the positioning to be chosen for insertion of the suction straw 80, after the respective seals L have been detached from the upper wall 11 of the carton pack 10. [ 0035 ] As can be seen from the figures , the first opening 12 and the second opening 13 are positioned eccentrically on the top wall 11 of the carton pack 10 , and can be respectively arranged close to diagonally opposite vertices of the top wall 11 of the carton pack 10 , as illustrated in Figure 1, or are transversely opposed, arranged close to the front and rear edges, respectively, of the top wall 11 of the carton package 10, as shown in Figure 2. In both cases, the two openings 12, 13 are eccentric and positioned at a distance from each other and on the sides of the upper wall 11 opposite to the center of the latter, as illustrated in figures 1 and 2 of the attached drawings.
[ 0036 ] Com o arran j o construtivo proposto, o usuário destaca os lacres L das duas aberturas 12 , 13 da parede superior 11 da embalagem cartonada 10 e introduz o extremo chanfrado 81 do canudo 80 através de uma das referidas aberturas 12 , 13 , situação na qual a outra abertura pas sa a operar como abertura de ventilação, permitindo uma fácil e completa extração do produto liquido, sem exigir um inadequado e desconfortável es forço de sucção por parte do usuário adulto ou infantil e sem os riscos de indese j áveis derrames de liquido para fora da embalagem cartonada, através da abertura de ventilação desprovida do canudo 80 mas provida da respectiva válvula de retenção VR . Nes sa nova solução construtiva, os lacres L são destacados da embalagem e não empurrados para o seu interior . [ 0036 ] With the proposed constructive arrangement, the user detaches the seals L from the two openings 12, 13 of the upper wall 11 of the carton pack 10 and introduces the chamfered end 81 of the straw 80 through one of said openings 12, 13, situation in which the other opening operates as a ventilation opening, allowing an easy and complete extraction of the liquid product, without requiring an inadequate and uncomfortable suction effort by the adult or child user and without the risk of undesirable spills of liquid out of the carton package, through the ventilation opening devoid of the straw 80 but provided with the respective non-return valve VR. In this new constructive solution, the L-seals are detached from the packaging and not pushed into it.
