Abstract

The container consists of flexible material, essentially of a round fabric made of polyolefins, on whose upper edge in this case four loops (1) are sewn. In this case, the arrangement is such that each loop (1) consists of a relatively wide strip of material, both ends (2, 2') of which overlap the upper container edge (10) and are sewn to the latter spaced apart laterally, and whose central part (3), forming the suspension eye, is drawn together in the manner of a tape. By this means, loops are formed in a relatively simple manner, adjoining which loops there is a large number of warp threads of the round fabric and which in this way have a high load-bearing capacity, the resistance to tensile force at the loops themselves being increased by being drawn together. <IMAGE>

DESCRIÇÃODESCRIPTION

A presente invenção refere-se a um recipiente de material flexível, essencialmente a partir de um tecido circular de poliolefina.The present invention relates to a container of flexible material, essentially from a circular polyolefin fabric.

Em muitos domínios de aplicação, os sacos feitos a partir de um tecido circular têm dado boas provas, tendo sido obtidos bons resultados com materiais para sacos de, além da juta, também em especial de poliolefinas, por exemplo polipropilenos (PP) ou polietilenos (PE), que são entretecidos sob a forma de fitinhas planas. Os sacos feitos de tais tecidos são resistentes aos produtos químicos, insensíveis à água, higiénicos, activadores da respiração, imputrescíveis, etc.In many fields of application, bags made from a circular fabric have proven to be successful, with good results having been obtained with bag materials, in addition to jute, also in particular polyolefins, for example polypropylenes (PP) or polyethylene ( PE), which are interwoven in the form of flat ribbons. The bags made of such fabrics are resistant to chemicals, insensitive to water, hygienic, breath activators, rot resistant, etc.

A fim de poderem utilizar-se tais sacos tecidos também para produtos a granel com os grãos mais finos e higroscópicos, tais como cimento, é conhecido o processo de intriduzir no saco tecido um saco interior de um material impermeável à humidade, por exemplo uma folha de polietileno soprada.In order to be able to use such woven bags also for bulk products with the finest and hygroscopic grains, such as cement, the process of inserting an inner bag of a material impermeable to moisture, for example a sheet, is known blown polyethylene.

Em muitos casos há o desejo de poder utilizar baDOWQ'NAL In many cases there is a desire to be able to use baD OWQ ' NAL

tais sacos conhecidos com ou sem saco interior também com dimensões da ordem de grandeza das dos contentores com um peso do produto de enchimento de por exemplo 1000 Kg ou mais. No que respeito à resistência à rotura dos materiais de que sao feitos esses sacos não surgem aqui regra geral problemas, mas pelo con trário sao postos limites à capacidade de carga de tais recipientes devido aos laços para o transporte dos recipientes por meio de equipamentos de elevação, tais como gruas, guindastes, etc, conhecidos até agora, em regra fixados por costura, visto que os pequenos laços até agora usados, de tecido de poliamida ou similar apenas podem suportar o peso transmitido o esforço a apenas poucos fios de teia. De aoordo com isso, foram já usados laços com cintas atadas por baixo, mas então as despesas de material e fabrico tomavam-nos já pouco económicos. Isso precisamente no caso de produtos de grande massa, como é caso das embalagens que estamos a considerar, é da máxima importância.such known bags with or without inner bag also with dimensions of the order of magnitude of those of the containers with a weight of the filler product of for example 1000 kg or more. With regard to the breaking strength of the materials from which these bags are made, there are generally no problems here, but on the contrary, limits are placed on the loading capacity of such containers due to the loops for transporting the containers by means of lifting equipment. , such as cranes, cranes, etc., known until now, usually fixed by sewing, since the small loops hitherto used, made of polyamide fabric or the like, can only support the weight transmitted to only a few strands of web. According to this, ties with straps tied underneath were already used, but then material and manufacturing expenses made them uneconomical. This is precisely the case in the case of mass products, such as the packaging we are considering, of the utmost importance.

objecto da presente invenção consiste portanto em proporcionar um recipiente do tipo anterior, cujos laços transmitam a força de tracção, quando da elevação da carga, substancialmente a um maior número de fios de teia, sem a necessidade de reforços, de cintas atadas por baixo, etc, e isso com custos de fabricação favoráveis.object of the present invention is therefore to provide a container of the previous type, whose loops transmit the pulling force, when the load is raised, substantially to a greater number of warp threads, without the need for reinforcements, of straps tied underneath, etc., and this with favorable manufacturing costs.

Segundo a presente invenção isso consegue-se se cada um dos laços for constituído por uma fita de material relativamente larga, cujas duas extremidades se sobrepõem ao bordo superior do recipiente e são cosidas com este bordo lateralmente, afastadas uma da outra, e se a sua parte média que forma o olhai de suspensão for unida como uma fita.According to the present invention, this is achieved if each of the loops consists of a ribbon of relatively wide material, the two ends of which overlap the upper edge of the container and are sewn with this edge laterally, apart from each other, and if its middle part that forms the hanging eye is joined like a ribbon.

Como se compreende sem mais, a tira de material apoia-se agora com as suas extremidades numa grande superfície, num grande número de fios de teia, de modo que resulta daí também correspondentemente uma elevada câpacidade de carga, sendo a resistência à tracção no próprio olhai adicionalmente aumen2As you can easily understand, the strip of material now rests with its ends on a large surface, in a large number of warp threads, so that correspondingly also results in a high load capacity, the tensile strength being itself look additionally aumen2

tada devido à aniao como uma fita. Ás extremidades de grande superfície da tira de material podem além disso ser bem cosidas, de modo que resulta um recipiente muito económico. Pode deste modo utilizar-se um tecido mais leve, para a superfície lateral do recipiente, que anteriormente, para a mesma carga. Formas de realização aperfeiçoadas convenientes do recipiente segundo a presente invenção resultam então se a parte média de cada laço for unida como uma fita, mediante uma ou mais torções da fita antes de a coser no bordo superior do recipiente ou se a parte média de cada'laço for unida por meio de um franzido ou uma dobra, apresentando então de preferência a parte média unida como uma fita pelo menos uma costura transversal de preferência a meio,, a fim de impedir a separação da parte média em forma de fita.due to anion like a ribbon. The large surface ends of the strip of material can furthermore be well stitched, so that a very economical container results. In this way, a lighter fabric can be used for the side surface of the container than previously for the same load. Conveniently improved embodiments of the container according to the present invention then result if the middle part of each loop is joined like a ribbon, by means of one or more twists of the ribbon before sewing it on the upper edge of the container or if the middle part of each ' loop is joined by a frown or a fold, then preferably showing the middle part joined as a ribbon at least one cross-sectional seam preferably in half, in order to prevent the separation of the middle part in the form of tape.

Pode, além disso, também ser conveniente que a fita de material que forma um laço seja feita de um tecido circular planificado de uma poliolefina.In addition, it may also be convenient for the ribbon of material that forms a loop to be made of a flat polyolefin circular fabric.

Nesse caso é conveniente que o tecido circular seja constituido por fitinhas de polipropileno ou de polietileno.In this case, it is convenient that the circular fabric is made of polypropylene or polyethylene ribbons.

Outras vantagesns resultam da forma de realização do objecto da presente invenção descrita a seguir com referência ao desenho anexo que representa um recipiente em perspectiva.Other advantages result from the embodiment of the object of the present invention described below with reference to the attached drawing representing a perspective container.
