Description

Descrição referente à patente de invenção de UNILEVER N.V., holandesa, industrial e comercial, com sede em Burgemeester s'Jacobplein 1, NL-3000 DK Rotterdam, Países Baixos, (inventor» Valter Ramspott, residente na Alemanha Ocidental), para PROCES SO PARA A FABRICAÇÃO DE UMA EMBALAGEM”»Description referring to the UNILEVER NV, Dutch, industrial and commercial patent, based in Burgemeester s'Jacobplein 1, NL-3000 DK Rotterdam, Netherlands, (inventor »Valter Ramspott, residing in West Germany), for PROCES SO PARA MANUFACTURING A PACKAGE ”»

DESCRIÇÃODESCRIPTION

A presente invenção refere-se a um processo para a fabricação de uma embalagem, em particular a partir de um molde que forma uma só peça provido no interior com um meio auxiliar para facilitar a abertura da embalagem por raagamento, por exemplo sob a forma de um fio.The present invention relates to a process for the manufacture of a package, in particular from a mold that forms a single piece provided inside with an auxiliary means to facilitate the opening of the package by ripping, for example in the form of a wire.

Fios para rasgar ou meios auxiliares semelhantes têm sido usados com êxito para embalagens muito diferentes. As suas duas extremidades encontram-se na junta longitudinal, onde pode pegar-ae uma extremidade. Mas surgem dificuldades importantes quando se executa esta junta longitudinal - que Ó feita por selagem - devido ao aumento da espessura do meio auxiliar de abertura, onde se verifica a sua sobreposição.Tear threads or similar auxiliary means have been used successfully for very different packaging. Its two ends are at the longitudinal joint, where you can catch it and one end. However, important difficulties arise when this longitudinal joint is made - which is made by sealing - due to the increase in the thickness of the auxiliary opening means, where it overlaps.

O objecto da presente invenção consiste portanto em localizar o meio auxiliar da abertura de modo tal que se evite uma acumulação de material.The object of the present invention is therefore to locate the auxiliary means of the opening in such a way as to avoid material accumulation.

Na solução deste problema proposta pela presente invenção, o meio auxiliar de abertura estende-se segundo um ligeiro angulo com os bordos do molde original.In solving this problem proposed by the present invention, the auxiliary opening means extends at a slight angle with the edges of the original mold.

Isso significa que as duas extremidades do meio auxiliar de abertura ficam próximas uma da outra e não uma em cima da outra, de modo que não surgem problemas quando se executa a junta selada longitudinal.This means that the two ends of the auxiliary means of opening are close to each other and not on top of each other, so that no problems arise when the longitudinal sealed joint is made.

Ê também muito vantajoso que, segundo a presente invenção, o meio auxiliar de abertura seja fixado na direcção de máquinaIt is also very advantageous that, according to the present invention, the auxiliary opening means is fixed in the machine direction

da folha de cartão ou material análogo que contém o molde, enquanto os moldes são colocados sobra a folha de cartão ou material segundo um ligeiro ângulo.of the cardboard sheet or similar material containing the mold, while the molds are placed on the cardboard sheet or material at a slight angle.

Isso torna possível fabricar moldes que incluem o meio auxiliar de abertura de maneira muito eficiente e económica.This makes it possible to manufacture molds that include the opening aid very efficiently and economically.

Demonstrou-se ser completamente apropriado que, segundo a presente invenção, o meio auxiliar de abertura se estenda segundo um ângulo de cerca de 1° com os bordos do molde.It has been shown to be completely appropriate that, according to the present invention, the auxiliary opening means extends at an angle of about 1 ° with the edges of the mold.

No desenho anexo está representada uma forma de realização da presente invenção. A figura mostra uma secção de uma folha de cartão na qual se proporcionaram doze moldese (l) é uma folha de cartão na qual se proporcionaram doze moldes (2) idênticos, usados para produzir uma embalagem de cartão. Estes moldes (2) estão colocados segundo um ângulo de 1° com os bordos da folha de cartão (l). Um fio de rasgamento (3), que corre paralelamente aos bordos da folha de cartão (l) e portanto na direcção de máquina estende-se através de cada fiada destes moldes (2). Por outro ledo, ele corre segundo um ângulo de 1° relativamente aos bordos e âs linhas de dobragem dos moldes individuais (2).In the attached drawing an embodiment of the present invention is shown. The figure shows a section of a cardboard sheet in which twelve molds are provided and (1) is a cardboard sheet in which twelve identical molds (2) are used to produce a carton. These molds (2) are placed at an angle of 1 ° with the edges of the cardboard sheet (1). A tearing thread (3), which runs parallel to the edges of the cardboard sheet (1) and therefore in the machine direction extends through each row of these molds (2). On the other hand, it runs at an angle of 1 ° with respect to the edges and fold lines of the individual molds (2).
