Description

SACOLA DE PAPEL DOBRADA E PROCESSO DE MONTAGEM ASSOCIADO FOLDED PAPER BAG AND ASSOCIATED ASSEMBLY PROCESS
Setor tecnológico da invenção Technological invention sector
[0001] A presente invenção pertence, de maneira geral, ao setor tecnológico de sacolas e embalagens destinadas a armazenar e transportar uma diversidade de artigos, do tipo que normalmente é utilizada no comércio para os clientes levarem os artigos adquiridos, mas que pode ter uma série de outros usos. Estas sacolas podem ser manufaturadas em papel ou outro material cujas propriedades permitam obter o mesmo resultado, sendo que invenção se refere a uma sacola, preferencialmente de papel, com aspecto de bolsa, que pode ser montada sem o uso de nenhum adesivo. [0001] The present invention belongs, in general, to the technological sector of bags and packaging intended for storing and transporting a variety of articles, of the type that is normally used in commerce for customers to carry purchased articles, but which may have a series of other uses. These bags can be manufactured from paper or other material whose properties allow obtaining the same result, and the invention refers to a bag, preferably made of paper, with the appearance of a purse, which can be assembled without the use of any adhesive.
Estado da técnica conhecido Known state of the art
[0002] Estas sacolas de papel convencionais são constituídas por uma folha de papel que é dobrada e colada, ou seja, se utilizam de colagem para obter o fechamento lateral e do fundo. As extremidades opostas da lâmina de papel são unidas por adesivo num movimento horizontal para formar o corpo da sacola e o fundo exige a colagem de partes independentes para ser formado. A união das partes da sacola por adesivo é um aspecto de fragilidade e isto é particularmente verdadeiro para o fundo, pois como este suportará o peso do que for transportado, se torna o ponto mais frágil da sacola. [0002] These conventional paper bags are made up of a sheet of paper that is folded and glued, that is, they use gluing to obtain side and bottom closure. The opposite ends of the paper sheet are joined by adhesive in a horizontal movement to form the body of the bag and the bottom requires the gluing of independent parts to be formed. The joining of the bag's parts by adhesive is an aspect of fragility and this is particularly true for the bottom, as this will support the weight of whatever is transported, it becomes the bag's weakest point.
[0003] Cita-se como exemplo de patente deste tipo o BR 202014019382-6, que revela uma sacola obtida a partir de uma folha de cartão, cartolina, papel ou similares, que é vincada, cortada, dobrada e colada, sendo dotada de reforços para o fundo e da virada superior. Diversas outras sacolas e embalagens formadas por folhas de papel são conhecidas, diferenciando-se pela configuração de vincos e dobras que realizam para obter a forma montada da sacola, como as reveladas nos documentos US2669382, US3342402, US6176615 e US2010/0111447. Todas estas sacolas tem em comum a necessidade de colagem para serem montadas. [0003] BR 202014019382-6 is cited as an example of a patent of this type, which reveals a bag obtained from a sheet of cardboard, cardboard, paper or similar, which is creased, cut, folded and glued, being equipped with reinforcements for the bottom and top facing. Several other bags and packagings formed by sheets of paper are known, differing by the configuration of creases and folds that are made to obtain the assembled shape of the bag, such as those disclosed in documents US2669382, US3342402, US6176615 and US2010/0111447. All these bags have in common the need for gluing to be assembled.
[0004] A utilização de colagem para fabricar as sacolas acarreta em uma série de problemas e inconvenientes, como o custo dos equipamentos para colagem, insumos necessários, tempo de cura da cola, espaço físico necessário e adequações ao descarte dos resíduos. Além disso, a colagem é por natureza suscetível a falhas, acarretando perdas no processo de produção, bem como contratempos e até avaria do que estiver sendo transportado, quando em utilização. Também é a etapa mais cara e demorada do processo produtivo. Seja a sacola montada manualmente ou em maquinário, o tempo necessário à colagem é o maior entre todas as etapas do processo. Nestas sacolas convencionais, a produção de pequenas e médias quantidades e variedade de tamanhos não justifica o custo com o acerto de máquina. [0004] The use of gluing to manufacture bags leads to a series of problems and inconveniences, such as the cost of gluing equipment, necessary inputs, glue curing time, necessary physical space and adjustments to waste disposal. Furthermore, gluing is by nature susceptible to failure, causing losses in the production process, as well as setbacks and even damage to whatever is being transported, when in use. It is also the most expensive and time-consuming step in the production process. Whether the bag is assembled manually or using machinery, the time required for gluing is the longest among all stages of the process. In these conventional bags, the production of small and medium quantities and a variety of sizes does not justify the cost of adjusting the machine.
Novidade e objetivo da invenção Novelty and purpose of the invention
[0005] A presente invenção se refere a uma sacola formada por papel (ou outro material com propriedades semelhantes) dobrado e encaixado, que dispensa o uso de cola e obtém um aspecto visual de “bolsa”. Uma lâmina de papel vincada para dobras e cortes é o “mapa” para a formação do corpo estrutural da embalagem, o que possibilita a comercialização das lâminas acompanhadas de reforços e alças, de modo que o próprio estabelecimento comercial possa fazer a montagem em segundos, reduzindo assim o custo na aquisição, armazenagem, cubagem, peso/transporte e acomodação. [0006] A retirada da colagem do processo reduz consideravelmente o preço final e resulta num produto que, mesmo sendo fechado à mão, é competitivo em relação as sacolas montadas e coladas por maquinário. Sendo que este modelo sem-cola pode também ser montado por maquinário. Outras vantagens da não utilização de cola são que pessoas não terão mais contato com produto perigoso e a sacola tem um descarte mais apropriado para reciclagem. Além disso, a eliminação da cola permite obter uma sacola mais resistente, sem a fragilidade do fundo inerente às sacolas convencionais e, ainda, cujo processo produtivo utiliza os mesmos recursos, métodos e maquinários existentes, porém, reduzindo os insumos e tempo de produção. [0005] The present invention refers to a bag made of paper (or other material with similar properties) folded and fitted together, which eliminates the use of glue and obtains a “bag” visual appearance. A sheet of paper creased for folding and cutting is the “map” for the formation of the structural body of the package, which makes it possible to sell the sheets accompanied by reinforcements and handles, so that the commercial establishment itself can assemble it in seconds, thus reducing the cost of acquisition, storage, cubing, weight/transport and accommodation. [0006] Removing gluing from the process considerably reduces the final price and results in a product that, even though it is closed by hand, is competitive compared to bags assembled and glued by machinery. This glueless model can also be assembled using machinery. Other advantages of not using glue are that people will no longer have contact with dangerous products and the bag can be disposed of more appropriately for recycling. Furthermore, the elimination of glue makes it possible to obtain a more resistant bag, without the fragility of the bottom inherent to conventional bags and, also, whose production process uses the same resources, methods and existing machinery, however, reducing inputs and production time.
[0007] Quanto ao processo de montagem da sacola propriamente dito, de modo diverso da maioria das sacolas de papel conhecidas, em que as extremidades opostas de uma lâmina de papel são unidas (coladas) num movimento horizontal para formar o corpo da sacola, na presente invenção a lâmina de papel é dobrada num movimento vertical, obtendo um corpo com uma configuração em “U”, tendo em extremidades opostas um fundo inteiro e a abertura da embalagem. O fundo inteiro suporta o peso do que for transportado e dota a sacola de uma resistência superior. [0007] As for the bag assembly process itself, unlike most known paper bags, in which the opposite ends of a sheet of paper are joined (glued) in a horizontal movement to form the body of the bag, in In the present invention, the paper sheet is folded in a vertical movement, obtaining a body with a “U” configuration, having at opposite ends an entire bottom and the opening of the package. The entire bottom supports the weight of whatever is being transported and gives the bag superior resistance.
[0008] Nesta concepção, uma vez o corpo da sacola armado, obtém-se em cada lado duas abas. Cada uma oriunda de uma das faces frontal e posterior. Estas abas se acomodam uma ao lado da outra, formando uma parede dupla e originando as laterais da sacola, o que torna o corpo da sacola efetivamente fechado nas suas laterais, novamente sem a necessidade de colagem. [0009] A folha de papel é provida de furos para a passagem de alças em pontos estratégicos, de modo a neste estágio da montagem estarem dispostos apenas nas extremidades superiores das laterais, evitando as faces frontal e posterior da sacola. Uma vez que as alças são aplicadas apenas nas laterais, causam a impressão de serem embutidas nas faces frontal e posterior e proporcionam aspecto de bolsa para a sacola. [0008] In this design, once the body of the bag is assembled, two flaps are obtained on each side. Each one coming from one of the front and back faces. These flaps are placed next to each other, forming a double wall and forming the sides of the bag, which makes the body of the bag effectively closed on its sides, again without the need for gluing. [0009] The paper sheet is provided with holes for the passage of handles at strategic points, so that at this stage of assembly they are arranged only at the upper ends of the sides, avoiding the front and back faces of the bag. Since the straps are only applied to the sides, they give the impression of being embedded in the front and back sides and provide a bag-like appearance to the bag.
[0010] Na abertura da sacola estão abas de dobras, voltadas para a parte interna das faces frontal, posterior e laterais, formando uma “gola” em “U”. Dita gola visa acomodar perfis que conferem rigidez e resistência, com a mesma largura das faces e altura preferencial entre 3 e 5 cm. Cada perfil realiza papel importante na funcionalidade efetiva do produto. Uma vez que as alças são aplicadas às laterais, quando a sacola transporta algum artigo, o peso deste naturalmente tenderia a tencionar a abertura, deformando-a. Para não deformar a abertura, são aplicados perfis com determinada rigidez, embutidos um em cada lado da abertura, para suportar a tensão causada pelo peso transportado, mantendo a abertura na forma que se propõe. [0010] At the opening of the bag there are fold flaps, facing the inside of the front, back and side faces, forming a “U” shaped “collar”. This collar aims to accommodate profiles that provide rigidity and resistance, with the same width of the faces and a preferred height between 3 and 5 cm. Each profile plays an important role in the effective functionality of the product. Since the handles are applied to the sides, when the bag carries an item, its weight would naturally tend to strain the opening, deforming it. To avoid deforming the opening, profiles with a certain rigidity are applied, embedded one on each side of the opening, to withstand the tension caused by the weight transported, keeping the opening in the proposed shape.
[0011] Para o travamento da estrutura permanentemente nesta condição e, em substituição a cola, utiliza-se a furação das laterais e alças que são passadas nesses furos. Em uma concretização preferencial da invenção, são previstos dois furos em cada uma das duas laterais, dispostos mais próximos da parte superior das laterais, separados e divididos por um vinco central. Quando a alça está em utilização, força cada lado formado pela dobra entre os furos um contra o outro, trazendo consigo também cada uma das faces da embalagem. Provocando assim o fechamento da boca da sacola e lhe conferindo um aspecto de bolsa. Em outras concretizações da invenção, pode-se também acrescer furos na extremidade superior de cada face e utilizar a própria alça para fechamento da abertura com laço, provendo ao item a função de embalagem de presente. [0011] To permanently lock the structure in this condition and, instead of glue, drill the sides and handles that are passed through these holes. In a preferred embodiment of the invention, two holes are provided on each of the two sides, arranged closer to the upper part of the sides, separated and divided by a central crease. When the handle is in use, it forces each side formed by the fold between the holes against each other, also bringing with it each of the sides of the package. Thus causing the mouth to close of the bag and giving it a purse-like appearance. In other embodiments of the invention, holes can also be added to the upper end of each face and the handle itself can be used to close the opening with a bow, providing the item with the function of gift packaging.
[0012] A configuração dos vincos e dobras da folha de papel visa obter, quando a sacola é montada, a formação de estruturas triangulares sobrepostas no fundo, que aumentam sobremaneira a resistência do conjunto. [0012] The configuration of the creases and folds of the paper sheet aims to obtain, when the bag is assembled, the formation of triangular structures superimposed on the bottom, which greatly increase the resistance of the assembly.
[0013] Uma vez a sacola montada, pode ser compactada para armazenamento e, devido a sua concepção, a contração da estrutura é feita pelas laterais e fundo, preservando assim ambas as faces de qualquer dobra. [0013] Once the bag is assembled, it can be compacted for storage and, due to its design, the structure is contracted on the sides and bottom, thus preserving both sides from any folding.

Descrição detalhada da invenção Detailed description of the invention
[0034] A presente invenção se refere a uma sacola de papel dobrada constituída por uma lâmina de papel (1) vincada para dobra e com corte de aberturas (2), que forma o guia para a montagem de dita sacola. [0034] The present invention refers to a folded paper bag consisting of a sheet of paper (1) creased for folding and with openings cut (2), which forms the guide for assembling said bag.
[0035] Conforme pode ser visualizado nas figuras 1 a 6, a concretização preferencial da invenção prevê uma folha (1) dotada em suas extremidades de linhas vincadas longitudinais paralelas, destinadas à dobra, doravante denominadas linhas longitudinais extremas (3), que formam a cintura (4) da boca da sacola (visualizada na figura 4) e que permite a introdução de reforço (5) (que pode ser visualizado na figura 8), quando pela forma e dimensões da sacola este for necessário. [0035] As can be seen in figures 1 to 6, the preferred embodiment of the invention provides for a sheet (1) provided at its ends with parallel longitudinal creased lines, intended for folding, hereinafter referred to as extreme longitudinal lines (3), which form the waist (4) of the bag mouth (viewed in figure 4) and which allows the introduction of reinforcement (5) (which can be seen in figure 8), when due to the shape and dimensions of the bag this is necessary.
[0036] Perpendicularmente às linhas longitudinais extremas (3) e nas extremidades da folha (1), estão dispostas linhas vincadas transversais paralelas, doravante referidas como linhas transversais extremas (6), que definem a área que formará as laterais da sacola. Ditas linhas transversais extremas (6) interceptam as linhas longitudinais extremas (3) e formam regiões retangulares (7), no centro das quais estão dispostas as aberturas (2), de forma que tais aberturas (2) coincidam quando as linhas longitudinais (3) são dobradas para formar a cintura da abertura da sacola. As aberturas (2) visam receber a introdução de alças (8) (ilustrada na figura 8). [0036] Perpendicular to the extreme longitudinal lines (3) and at the ends of the sheet (1), parallel transverse creased lines are arranged, hereinafter referred to as extreme transverse lines (6), which define the area that will form the sides of the bag. Said extreme transverse lines (6) intersect the extreme longitudinal lines (3) and form rectangular regions (7), in the center of which the openings (2) are arranged, so that such openings (2) coincide when the longitudinal lines (3 ) are folded to form the waist of the bag opening. The openings (2) are intended to receive the introduction of handles (8) (illustrated in figure 8).
[0037] No centro da folha (1) há três linhas vincadas paralelas às linhas longitudinais extremas (3), doravante chamadas linhas longitudinais centrais (9). Estas linhas longitudinais centrais (9) definem a região que formará o fundo da sacola. Na intersecção dessas linhas longitudinais centrais (9) com as linhas transversais extremas (6) formam-se regiões quadradas (10), que são divididas por linhas vincadas diagonais (11), que formam regiões triangulares (12), que ao serem dobradas exercerão relevante papel na rigidez estrutural da sacola. [0037] In the center of the sheet (1) there are three creased lines parallel to the extreme longitudinal lines (3), hereinafter called central longitudinal lines (9). These central longitudinal lines (9) define the region that will form the bottom of the bag. At the intersection of these central longitudinal lines (9) with the extreme transverse lines (6), square regions (10) are formed, which are divided by diagonal creased lines (11), which form triangular regions (12), which when folded will exert important role in the structural rigidity of the bag.
[0038] Estas linhas longitudinais extremas (3), linhas transversais extremas (6) e linhas longitudinais centrais (9), delimitam as áreas (13) que formarão as faces frontal e posterior da sacola. [0038] These extreme longitudinal lines (3), extreme transverse lines (6) and central longitudinal lines (9) delimit the areas (13) that will form the front and back faces of the bag.
[0039] A invenção ainda compreende o processo de montagem da sacola. A figura 9 representa o primeiro passo, a dobra das linhas longitudinais extremas (3) para formar a cintura da sacola em torno do reforço (5) (quando este for necessário). [0039] The invention also comprises the process of assembling the bag. Figure 9 represents the first step, the fold of the extreme longitudinal lines (3) to form the waist of the bag around the reinforcement (5) (when necessary).
[0040] Na figura 10 vemos o segundo passo, a dobra da região que formará as laterais da sacola em direção do interior da lâmina (1) através da dobra das linhas transversais extremas (6). [0040] In figure 10 we see the second step, the folding of the region that will form the sides of the bag towards the inside of the blade (1) through the folding of the extreme transverse lines (6).
[0041] A etapa seguinte é o levantamento das faces frontal e posterior da sacola (13) (representada nas figuras 11 e 12), pela dobra das linhas longitudinais centrais (9), formando o fundo da sacola. Neste movimento ocorre naturalmente a dobra e sobreposição das regiões triangulares (12) no fundo da sacola e a sobreposição das regiões das linhas transversais extremas (6), formando as laterais duplas da sacola. Para obter a fixação basta introduzir uma metade da cintura (4) dentro da outra metade (como ilustrado nas figuras 13 e 14), obtendo o corpo da sacola montado ilustrado pelas figuras 15 e 16. [0041] The next step is to lift the front and back faces of the bag (13) (represented in figures 11 and 12), by folding the central longitudinal lines (9), forming the bottom of the bag. In this movement, the folding and overlapping of the triangular regions (12) at the bottom of the bag and the overlapping of the regions of the extreme transverse lines (6) naturally occur, forming the double sides of the bag. To secure it, simply insert one half of the waistband (4) into the other half (as illustrated in figures 13 and 14), obtaining the assembled bag body illustrated in figures 15 and 16.
[0042] Por fim, basta introduzir as alças (8) e puxar para a face frontal e a face posterior (13) serem conduzidas uma contra a outra, tal como mostrado nas figuras 17 e 18. [0042] Finally, simply insert the handles (8) and pull so that the front face and the back face (13) are guided against each other, as shown in figures 17 and 18.
[0043] A sacola montada assim obtida pode ser compactada para ser estocada, como representado na figura 19, bastando empurras as faces frontal e posterior uma contra a outra até que encostem. [0043] The assembled bag thus obtained can be compacted for storage, as shown in figure 19, simply by pushing the front and back faces against each other until they touch.
[0044] Tratou-se no presente relatório descritivo de uma sacola de papel dobrada e processo de montagem associado, revestidos de aplicação industrial, novidade e atividade inventiva, todos os requisitos determinados pela legislação de propriedade industrial para receber o privilégio pleiteado. [0044] This descriptive report deals with a folded paper bag and associated assembly process, covered by industrial application, novelty and inventive activity, all the requirements determined by industrial property legislation to receive the claimed privilege.
