Description

The invention relates to the field of packaging, and more specifically to a method for the manufacture and packaging of a vessel of thermoplastic tape material for storing a product under pressure and consisting of a liquid and a gas dissolved in it.

The purpose of the invention is to preserve the quality of the product by completely filling the vessel and thereby eliminating the oxidation of the product with oxygen from the air.

Fig. 1 schematically shows a packaging machine on which the proposed method is implemented; in Fig. 2, a packaging tape with molded cavities and longitudinal bending lines; Fig. 3 shows a tube formed from extruded packaging tape; figure 4 is a vessel formed by double folded packing tape; figure 5 - the same, separated from the packaging tape; figure 6 - the same, with closed flanges; 7 - then the train is equipped with a supporting glass; Fig. 8 is a side view of the packaging tape with asymmetrically depressed cavities; figure 9 is a vessel obtained from the packaging tape.

The method is carried out as follows.

From the store coil 1 of the packaging machine, the metal tape 2, mainly of black tin, on which a layer of thermoplastic material is preliminarily applied, is wound up and passes between the rollers 3, which apply longitudinal folding lines. The tape then passes under a relatively large diameter guide coil 4 to prevent wrinkling and between two interacting pressing elements 5 and b, with which it is molded by pressing with simultaneous stretching of the material of the cavity 7 of the liner-shaped form.

After the tape is pressed, it bends to form tube 8 with a triangular cross-section a.

Then the longitudinal edges 9 of the belt 2 are pressed against one another, joined by melting a layer of thermoplastic material and pressed with pressure rollers 10. Melting can be carried out with hot air and using a high-frequency electromagnetic field. Through the inlet pipe 11, the formed tube is filled with product.

After the tube is filled with contents, which occurs continuously when a tube is formed, it is crimped around the entire perimeter.

This compression, which occurs below the outlet of the supply pipe, begins with the fact that the tube is pressed into flat sections, with the tape being bent along the central line of bending, while the side lines of bending are high ml. Subsequently, a closed cylindrical shaped container is formed in the middle part and in the shape of hemispheres along the ends. Full filling of the vessels during their formation excludes contact of the product with air oxygen and spoilage.

Since the liquid in which the gas is dissolved is packed in a vessel, internal pressure is quickly created in it. Therefore, the connection of flanges must be strengthened, which is achieved by bending the flanges, pressing it against the surface of the vessel and then rolling or rolling,

A series of pouring holes may be punched in the vessel, which subsequently close to the sweet.

For stability, the vessel can be equipped with an annular support cup (Fig. 7).

To pour out holes located directly on the end of the vessel, and not from the side, the cavity is formed asymmetrical (Fig.8).

The thickness of the sheet metal from which the vessel is made is chosen equal to 0.1-0.5 mm.

The vessel may be provided with printed text or a picture.

METHOD OF MANUFACTURE AND UPA. FORGES OF A VESSEL FROM A TAPE THERMOPLASTIC MATERIAL FOR STORING A PRODUCT UNDER PRESSURE AND CONSISTING OF LIQUID AND DISSOLVED IN IT GAS, including making a bend line around the tape, molding cavities, introducing cavities into the cavity by means of a pipe nozzle and sealing subsequent separation of the cavities from the tape, characterized in that, in order to maintain the quality of the product, the thermoplastic material is applied at least on one side to a metal tape, lin bends perform at least two by deforming the metal and arrange them parallel to each other and the longitudinal axis of the tape, cavities are formed into a sleeve-like shape symmetrically on both sides of the fold line with simultaneous extension of the tape material, then the tape is folded along the fold lines to form a tube with a cross section in the interior of the triangle, in which the shell-shaped cavities are arranged in pairs opposite one another and compress the aligned edges of the tape, the nozzle is introduced into the cavity at the bend point, and after filling the crimp they take the tube along the entire perimeter with the formation of a closed container of cylindrical shape in the middle part and in the form of hemispheres at the ends, while the flanges of the separated vessels are bent, pressed against the surface of the vessel and rolled or rolled.
