Abstract

Saco grande con pliegues laterales de material termoplástico con una costura de fondo soldada, caracterizado porque una pieza de manga (1), provista de pliegues laterales y colocada en forma plana, hecho de una lámina plástica, y que se ha reforzado por medio de tejidos o entrecruzados unidos con aquella, de cintas plásticas estiradas u otras inserciones, lleva una costura de fondo (2) que suelda herméticamente todas las capas, doblándose el extremo de la pieza de manga (1) provisto de la costura soldada (2) encima de aquella sobre éste y sujetándose en la zona de fondo una hoja cubridora de fondo (3) cubriendo concéntricamente el canto doblado (5), de la anchura de la pieza de manga (1) y la longitud del fondo rectangular estirado.Large bag with lateral folds of thermoplastic material with a welded bottom seam, characterized in that a piece of sleeve (1), provided with lateral folds and placed in a flat shape, made of a plastic sheet, and which has been reinforced by means of fabrics or cross-linked together with that, of stretched plastic tapes or other inserts, it has a bottom seam (2) that hermetically welds all the layers, bending the end of the piece of sleeve (1) provided with the welded seam (2) on top of it. that on it and a bottom covering sheet (3) covering concentrically the folded edge (5), the width of the sleeve part (1) and the length of the stretched rectangular bottom are held in the bottom area.

Description

II

Изобретение относитс  к складному мешку из термопластичного искусс гвенного материала со сварным швом днища.This invention relates to a foldable bag of thermoplastic material with a welded bottom seam.

Известны складные мешки, образованные из рукава, состо щего из нескольких термопластичных слоев и содержащего боковые стороны о вертикальной линией перегиба и дно со сварным швом .Folding bags are known that are formed from a sleeve consisting of several thermoplastic layers and containing lateral sides with a vertical inflection line and a bottom with a welded seam.

Недостатком известных мешков  вл етс  недостаточна  прочность днища мешка.A disadvantage of the known bags is the insufficient strength of the bottom of the bag.

Целью изобретени   вл етс  увеличение прочности мешка.The aim of the invention is to increase the strength of the bag.

Цель достигаетс  тем, что сварной шов днища образован из складки рукава , обращенной во внутрь мешка, при этом по центру изгиба складки прикреплен дополнительный внешний слой по размеру днища мешка.The goal is achieved by the fact that the weld seam of the bottom is formed from the fold of the sleeve facing the inside of the bag, while an additional outer layer is attached to the center of the fold of the fold by the size of the bottom of the bag.

На фиг. 1 показан складной мешок, снабженный днищем, вид сбоку в сложном состо нии на фиг. 2 - мешок, общий вид после его заполнени .FIG. 1 shows a collapsible bag fitted with a bottom, side view in a complicated state in FIG. 2 - bag, general view after filling.

. Уложенный в складки рукавный элемент 1, состо щий из прокладки (ткани или усиленной иньти способом пленки ) , сварен на нижнем конце сварным швом 2, охватывающим все слои. Сварной шов может быть выполнен радиационной сваркой или другими способами сварки, которые привод т к полному спеканию или сплавлению слоев. Снабженный cBafjpbiM швом 2 конец рукавного элемента If обращенный во внутрь мешка, образует складку 3, по центру изгиба складки прикреплен дополнительный внешний слой 4 на днище, который наклеен на рукавный элемент мешка гор чим жидким клеем.. The sleeve element 1, folded in folds, consisting of a gasket (fabric or reinforced film in the manner of a film), is welded at the lower end by a weld seam 2 covering all layers. The weld can be performed by radiation welding or other welding methods that lead to complete sintering or fusion of the layers. The end of the sleeve element If supplied to the cBafjpbiM with a seam 2 and facing the inside of the bag forms a fold 3, an additional outer layer 4 is attached to the bottom of the fold bend on the bottom, which is glued onto the bag sleeve with hot liquid glue.

Благодар  тому, что снабженный сварным швом конец рукавного куска отбортован, он не может вздуватьс  или распр мл тьс  и отталкивать дополнительный слой днища.Due to the fact that the end of the tubular piece welded to the seam is flanged, it cannot swell or spread out and push away the additional layer of the bottom.

Изобретение позвол ет изготавливать контейнерные мешки, которые ДО сих пор не могли быть изготовлены в виде складных мешков с боковыми складками.The invention permits the manufacture of container bags that, up to now, could not be made in the form of foldable bags with side folds.
