No saco segundo o presente modelo de utilidade não existe a referida parte saliente, completando-se a válvula com uma peça inserida de material laminar como continuação da boca da válvula.In the bag according to the present utility model there is no said protruding part, the valve being completed with an insert of sheet material as a continuation of the valve mouth.

Descreve-se a seguir com mais pormenor ! ^ o presente modelo de utilidade, com referência aos desenhos ane xos, que mostram uma forma de realização ilustrativa, de modo nenhum limitativa, do conjunto do saco e da válvula incorporada, representando as várias figuras: A fig. 1, uma vista em alçado lateral s do conjunto do saco e da válvula; e A fig. 2, uma vista da parte do saco correspondente à válvula antes do fecho por costura da parte su perior do mesmo. 0 saco é constituído, como se mencionou, por um material tubular (1) que se dobra nos lados opostos por meio de três linhas longitudinais (2) e (3) para sobrepor as duas faces maiores do saco, formando uma estrutura plana de con torno rectangular, fechando-se as duas extremidades do saco por meio de costura sobre franjas da borda (4) dobradas sobre si mesmas, como se representa na fig. 1. 0 saco cortado apresenta, nas duas pare des adjacentes de um dos cantos, linhas de dobragem respectivas inclinadas (8), por meio das quais, de um prolongamento da linha central (3) do referido lado e duas linhas inclinadas (10) que unem as extremidades das linhas inclinadas (8) com a linha central (3) do lado, se dobra para dentro a referida parte do canto.Described below in more detail! the present utility model, with reference to the accompanying drawings, showing an illustrative embodiment, by no means limiting, of the assembly of the bag and of the incorporated valve, showing the various figures: Fig. 1 is a side elevational view of the bag and valve assembly; and Fig. 2 is a view of the portion of the bag corresponding to the valve before seaming the upper part thereof. The bag comprises, as mentioned, a tubular material (1) which folds on opposite sides by means of three longitudinal lines (2) and (3) to overlap the two larger faces of the bag, forming a flat concave structure and the two ends of the bag are closed by seaming over edge fringes 4 folded over each other, as shown in FIG. The cut bag has, in the two adjacent edges of one of the corners, inclined respective fold lines (8), by means of which an extension of the center line (3) of said side and two inclined lines (10) which join the ends of the inclined lines (8) with the center line (3) on the side, fold inwards said corner portion.

Deste modo, forma-se uma abertura superior (11) para encher o saco, na qual os bordos da mesma são as ] linhas inclinadas de dobragem (8) e que tem um fundo horizontal * constituído pelo prolongamento (3) da linha de dobragem central 2Thereby, an upper opening 11 is formed to fill the bag, in which the edges thereof are the folded inclining lines 8 and having a horizontal bottom * constituted by the extension 3 of the folding line central 2

or inside the corresponding side, as shown in Fig. The valve is completed with a rectangular blade (5) folded over itself to form a longer duct whose fold line (7), located in the lower position, engages the extension of the fold line (3) on the side in the mouth of the valve opening (11). The upper edges (12) of said blade (5) are situated between the upper edges (4) of the bag and aligned thereon, folding together to one side and fixing thereto by means of a line of perforations ( 6). For better attachment of the blade (5), the blade (5) may suitably be adhered to the adjacent walls of the bag. Said valve allows an easy filling of the package or bag, due to its flexibility, being closed automatically to prevent the product contained in the bag from escaping. Although it has been described and represents one embodiment of the utility model, it is clear that modifications may be made therein contained within the scope thereof, and the utility model should not be construed as limited to said embodiment, but rather by the appended claims. A bag for packaging granular or powdery products, having one of the upper corners provided with a filling aperture with a valve that prevents the posterior exit of the product, characterized in that the mouth of the valve is formed by the corresponding part of the folded corner inwardly by lines inclined downwardly and outwardly of the side walls, into the aperture so as to form a short horizontally disposed and open interior conduit and in that said conduit is extended by means of an inclined blade folded over itself to form a valve which, on the one hand, allows the filling of the bag and, on the other hand, implies in itself the exit of the product once filled said bag. Bag according to claim 1, | characterized in that it is constructed from an open tubular part at the ends, these ends being closed by stitching the folded edges to one side and affixing the edges of the folded blade on itself, which constitutes the filling valve, between the corresponding edges of the bag at its upper end. | The applicant claims the priority of the Spanish utility model application filed on February 8, 1991, under No. U9100378.

SUMMARY ft BAG FOR PACKAGING GRANULAR OR PULVERULENT PRODUCTS " The utility model relates to a process for packaging granular or powdery products having a filling aperture in one of the upper corners. This aperture is provided with a valve which then prevents the product from exiting. The valve mouth is formed by the corresponding portion of the said corner, folded inwardly by inclined lines (8) downwardly and outwardly of the sidewalls, into said aperture so as to form a horizontal, inwardly-open conduit. Said conduit extends through an inclined blade, folded over itself, to form a valve. The bag is constructed from a tubular piece (1) open at the ends, the latter being sealed by seaming the folded edges to one side, the edges of the folded blade fixing thereon to constitute the said valve, between the edges of the bag at its upper end.
