摘要： On décrit une valve pour un sac ou analogue devant se remplir d'air, laquelle valve comporte un élément tubulaire, étanche et essentiellement cylindrique (2) qui s'étend de l'intérieur à l'extérieur du sac, la partie extérieure de l'élément étant filetée à l'extérieur (21). Un bouchon à filetage interne (13) est destiné à s'enfiler sur le filetage externe (21) de l'élément tubulaire (2) afin de fermer hermétiquement l'extrémité (24) de ce dernier, et une valve de remplissage (15) se trouve au milieu du bouchon (1). Afin que le sac puisse se vider de façon simple et rapide, plusieurs évents (14) ont été ménagés dans le bouchon (1) dans la zone qui entoure la valve de remplissage (15), et l'extrémité de l'élément tubulaire (2) comprend, en face du bouchon (1), une bride interne (23) et de préférence annulaire dont la surface supérieure est serrée de manière hermétique contre la surface inférieure du bouchon et ferme les évents (14) de celui-ci lorsqu'il est entièrement vissé.

摘要： The invention relates to a pallet (1) made of recyclable cardboard and its method of manufacture. Beams (2) are formed of tube-like paper-board core pieces (3) arranged in line and of the cardboard (4) surrounding them, the beams being attached to each other crosswise in two layers so that the axes of the core pieces included in the beams are placed perpendicularly to the level of the pallet. In addition to the beams (2), the pallet (1) may include a covering plate (14) of cardboard and an intermediate plate (15) of cardboard between the layers of the beams. The invention is characterized in that, when assembling the beams (2), the paper-board core pieces (3) of essentially a round cross section are compressed in order to flatten them in the cross direction of the resulting beam. The diameter of the core pieces (3) is decreased by 1-20 %, suitably about 10 % in said direction during flattening. The flattening increases the contact surfaces between the core pieces (3) and the surrounding cardboard (4) on which the core pieces and the cardboard are glued to each other.

摘要： The invention relates to a sack (1) or a similar flexible package and a packing method based on the use of such a sack. The sack (1), which is intended for packing fine-ground material, is provided with a filling duct (3) leading inside the sack and made of flexible material and a bendable covering patch (12) protruding from the sack with the aid of which the end (11) of the filling duct can be closed after the filling of the sack. It is essential to the invention that the filing duct (3) extends at least to the bending line (13) of the covering patch (12) and preferably past it and that the filling duct (3) is, at least at the end thereof, narrower than the covering patch (12). Thus the covering patch (12) can be bent against the surface of the sack and attached thereto in such a way that it forms a uniform closing zone closing the end (11) of the filling duct in a cross-direction and extending to each side thereof.

摘要： The invention relates to a tarpaulin (1) comprising a woven basic fabric (2) made water-proof, and several fastening means (5, 6) for fastening the tarpaulin (1) to a transport means. A problem with previous tarpaulins has been that they are not alone able to bind the load but chains, for instance, have to be used. This problem is avoided by means of a tarpaulin according to the invention, which is characterized in that the warp yarns of the basic fabric (2) are multifilament yarns, and that areas (3) woven mainly with flat-film yarns as weft yarns and reinforced areas (4) woven with multifilament weft yarns having a greater thickness and tensile strength than warp yarns alternate in the basic fabric in the warp direction, the fastening means (5, 6) being attached to the reinforced areas (4) of the basic fabric (2).

摘要： The invention relates to a valve structure for a sack or the like to be filled with air, which valve structure comprises an essentially cylindrical tubular part (2) extending hermetically from the inside to the outside of the sack and having external threads (21) on the portion outside the sack, a plug with internal threads (13) to be screwed on the external threads (21) of the tubular part (2) to close the end (24) of the tubular part hermetically, and a filling valve (15) in the middle of the plug (1). To facilitate and accelerate the emptying of the sack, the present invention is characterized in that the plug (1) has several air exhaust holes (14) within the area surrounding the filling valve (15), and that at the end of the tubular part (2) facing the plug (1) there is an inner, preferably annular flange part (23), the upper surface of which is pressed hermetically against the lower surface of the plug closing the exhaust holes (14) of the plug, when the plug (1) is entirely screwed in its place.

摘要： L'invention se rapporte à un article de conditionnement de transport (1) et à un procédé de fabrication dudit article. Ledit article (1) est constitué par une palette de transport (2) et un conteneur souple (6) fixé à ladite palette. La palette (2) appartenant audit article de conditionnement de transport présente l'avantage d'être constituée par deux plaques profilées (3, 4) et par un ou plusieurs éléments de support (5). Le conteneur souple (6) et les pièces appartenant à la palette (2) sont entièrement fabriqués à partir de matériaux pouvant être traités dans une machine de pulpe à papier, tels que du papier ou du carton et, de ce fait, l'article de conditionnement se dégrade biologiquement si on le jette ou peut se recycler dans la fabrication d'un article analogue.
