Abstract

The present invention relates to a carton-like package (1) with faces reinforced with structural ribs (2), and characterised in that at least one of the faces is provided with structural reinforcing ribs (2) that form creases in the surface of the package, said creases increasing the resistance of the face on which they are located, as well as the compression-resistance of the package. The vertical ribs extend continuously or discontinuously between the vertices or on the side of the faces, depending on the resistance desired, forming geometrical figures on the faces of the package. The ribs form creases that are located on the major or minor surfaces of the package, and preferably form an upright or inverted V.

Description

DESCRIÇÃO  DESCRIPTION
" EMBALAGEM COM FACES REFORÇADAS " "PACKAGING WITH STRENGTHENED KNIVES"
O presente invento diz respeito a uma embalagem do tipo paralelepipédica com faces reforçadas por nervuras estruturais. É caracterizada por, pelo menos uma das suas faces, ser dotada de nervuras estruturais de reforço de maneira a formarem vincos na sua superfície, vincos esses que conferem resistência à face onde se encontra aplicado e que permitem aumentar a resistência à compressão. The present invention relates to a parallelepiped type package with faces reinforced by structural ribs. It is characterized in that at least one of its faces is provided with structural reinforcing ribs so as to form creases on its surface, which give resistance to the face to which it is applied and allow to increase the compressive strength.
É do conhecimento técnico geral a utilização de nervuras para aumento de resistência das mais variadas estruturas. No domínio do papel, o chamado cartão canelado utiliza já um conceito que pretende aumentar a resistência mecânica do papel. Com efeito, o cartão canelado é formado por pelo menos três folhas de papel das quais a folha interior forma caneluras e que uma vez juntas vão garantir um aumento considerável da resistência. It is generally known to use ribs to increase strength of various structures. In the field of paper, the so-called corrugated board already uses a concept that aims to increase the mechanical strength of paper. Indeed, the corrugated board is made up of at least three sheets of paper of which the inner sheet forms flutes and which once together will guarantee a considerable increase in strength.
No entanto, embalagens de cartão canelado nem sempre são as mais apropriadas quando se pretende imprimir imagens de qualidade nas faces da embalagem. However, corrugated packaging is not always the most appropriate when printing quality images on the sides of the package.
São assim utilizadas embalagens de cartolina com mais ou menos gramagem de acordo com a resistência estrutural necessária. A resistência estrutural da embalagem é importante se se considerar a necessidade de armazenamento e transporte das mesmas e o seu consequente empilhamento. Utilizam-se portanto cartolinas de maior gramagem para se garantir uma resistência estrutural necessária às várias operações a que se sujeita a embalagem. Como facilmente se compreende, cartolinas mais resistentes são necessariamente mais caras, facto que se traduz num aumento dos custos das embalagens. Heavy-duty cardboard packagings are therefore used according to strength. structural change required. The structural strength of the packaging is important considering the need for storage and transportation of the packaging and its consequent stacking. Larger cardstock is therefore used to ensure the structural strength required for the various operations to which it is subjected to packaging. As is easily understood, sturdier cardboards are necessarily more expensive, which translates into increased packaging costs.
Descobriu o requerente que a aplicação de nervuras para formar vincos nas faces da embalagem aumenta consideravelmente a resistência da mesma. Applicant has found that applying ribs to crease the faces of the package considerably increases the strength of the package.
O aumento da resistência fica a dever-se à formação de nervuras que provocam o aparecimento de células com limitação de tensão onde cada célula aumenta o limite à resistência num plano e pela distribuição da carga em painéis de células adjacentes. Por outro lado, a execução de nervuras numa superfície plana vai fazer aumentar a resistência à flexão The increase in resistance is due to the formation of ribs that cause stress-limiting cells to appear where each cell increases the resistance limit in one plane and the load distribution in adjacent cell panels. On the other hand, making ribs on a flat surface will increase the flexural strength.
Tal facto vai permitir a utilização de cartolina ou papel de gramagem inferior e portanto mais barato para a construção de embalagens cujas faces deva ser impressas para publicitarem os produtos que acondicionam por exemplo produtos alimentares. This will allow the use of lower weight paperboard or paper and therefore cheaper for the construction of packages whose faces must be printed to advertise the products which pack for example food products.
A descrição que se segue tem por base os desenhos anexos em que : The following description is based on the drawings Annexes where:
- a figura 1 representa de forma esquemática o esforço a que as embalagens estão sujeitas;  - Figure 1 shows schematically the stress to which the packages are subjected;
a figura 2a a 2c representam face frontais de embalagem respectivamente na figura 2a, de uma embalagem da técnica anterior e nas figuras 2b e 2c de acordo com o invento ;  Figures 2a to 2c represent front packaging faces respectively in Figure 2a of a prior art package and Figures 2b and 2c according to the invention;
- a figura 3 representa um embalagem planificada de acordo com o invento;  Figure 3 represents a planned package according to the invention;
- a figura 4, 5 e 6 outras embalagens planificadas com modelos de realização diferentes; e  - Figures 4, 5 and 6 other planned packages with different embodiments; and
- a figura 7 outras formas de realização do objecto do invento .  Figure 7 shows further embodiments of the object of the invention.
Conforme se pode observar na figura 1 as embalagens 1, nomeadamente as embalagens para produtos alimentares são sujeitas a um esforço estrutural de compressão, que pode ter efeitos críticos aquando da armazenagem e/ou transporte das referidas embalagens. É o que se passa com a embalagem representada na figura 2a cuja face frontal é lisa e que portanto a sua resistência é apenas devida à gramagem da cartolina, i.e com uma maior ou menor espessura das faces da embalagem. As can be seen from Figure 1, packages 1, in particular food packaging, are subjected to a structural compressive stress which may have critical effects on the storage and / or transport of such packages. This is the case with the package shown in Figure 2a whose front face is smooth and therefore its strength is only due to the weight of the cardboard, i.e. with a greater or lesser thickness of the package faces.
Nas figuras 2b e 2c estão representados dois modos de realização diferentes do invento. Como se pode observar, foram introduzidos nervuras 2 que vão configurar vincos em "V" , direito na figura 2b e invertido na figura 2c São estas nervuras 2 estruturais praticadas, pelo menos numa das suas faces da embalagem, que reforçam estruturalmente e aumentam a resistência a esforços a que são sujeitas as embalagens, nomeadamente à compressão. Estas nervuras de reforço formam vincos na superfície das faces da embalagem. Figures 2b and 2c show two different embodiments of the invention. As can be seen, ribs 2 are introduced which will configure "V" creases, right in figure 2b and inverted in figure 2c It is these structural ribs 2 practiced at least on one side of the package which structurally reinforce and increase the resistance to stress to which the packages are subjected, particularly to compression. These reinforcing ribs form creases on the surface of the package faces.
As referidas nervuras 2 formando vincos podem ser dispostas nas faces maiores ou menores da embalagem conforme se pode observar nas figuras anexas. Said creasing ribs 2 may be arranged on the larger or smaller faces of the package as shown in the accompanying figures.
De uma maneira geral poder-se-á dizer que as referidas nervuras se desenvolvem de uma maneira contínua entre os vértices ou dos lados das faces ou de forma descontínua, de acordo com a resistência que se pretende obter e formam figuras geométricas nas faces da embalagem. Tais figuras geométricas estão representadas nas figuras 4 a 7, nas faces maiores ou menores da embalagem. Generally it can be said that said ribs develop continuously between the vertices or sides of the faces or discontinuously, according to the desired strength and form geometric figures on the faces of the package. . Such geometric figures are shown in Figures 4 to 7 on the larger or smaller faces of the package.
Como se depreende as nervuras que formam os vincos com configuração apropriada são praticadas por cunhos e cortantes de dimensão apropriada a gramagem do papel. Tais cunhos e cortantes vão determinar a largura e profundidade das nervuras, dimensões essas que dependem da variados factores, nomeadamente da gramagem utilizada no papel, da forma da embalagem, da resistência pretendida. As can be seen the ribs that form the creases with proper configuration are practiced by wedges and cutters of appropriate size to the paper weight. Such wedges and cutters will determine the width and depth of the ribs, which dimensions depend on various factors, notably the weight used on the paper, the shape of the package, the desired strength.
Os referidos vincos podem também apresentar a forma de meia-cana. Exemplo Said creases may also be in the shape of a half cane. Example
A título de exemplo indica-se que as faces de embalagem da figura 2a, 2b e 2c apresentam limites à compressão vertical respectivamente de 2,8 bar, 3,2 bar e 3,5 bar. Daqui se pode concluir que a forma do vinco influencia a resistência que se pretende obter. By way of example, it is indicated that the packaging faces of Figures 2a, 2b and 2c have vertical compression limits of 2.8 bar, 3.2 bar and 3.5 bar respectively. From this it can be concluded that the shape of the crease influences the strength to be obtained.
Outro factor a considerar na configuração do vinco a escolher, evidentemente depois da resistência que se pretende obter, consiste na imagem que eventualmente se pretenda obter aproveitando ou não a configuração do cinco que por exemplo pode limitar a mancha de impressão. De qualquer forma se for necessário preencher toda a face com um imagem impressa, o vinco, seja qual for a sua configuração, não influi negativamente uma vez que pode passar despercebido na imagem impressa. Another factor to consider in the configuration of the crease to be chosen, of course after the strength to be obtained, is the image which one may wish to obtain by taking advantage of the configuration of the five which for example may limit the print spot. However if it is necessary to fill the entire face with a printed image, the crease, whatever its configuration, does not influence negatively as it may go unnoticed in the printed image.
