Description

Process for the production of internally clad containers, bottles and the like. An internally clad container is already known which is produced as a result is that the container consisting of the plating material from the head of the Outer container from; starts and afterwards by air or liquid pressure presses against the inner wall of the outer container.

The upper opening corresponds to the clear diameter of the container. In the case of containers or bottles for compressed gases and the like, however, the container must be on the head ; a rather small throat opening; preserved. Attempts have therefore been made to make the inner plating layer in the form of a container to be inserted into the outer container before the completion of the neck and then this: the container used in the manufacture of the container neck to process.

It has now been found that the shocks and vibrations that occur during forging, a slight displacement; of the thin-walled, inserted Cause insert container, whereby, deformation, bulging and wrinkling occurs. In addition, the inner container head of the main container must be checked for wrinkles, Cracks and dl. as well as removal of scale after forging impossible because of Insert container covers the area of the actual container body.

According to the invention, the disadvantages described are avoided by a process for the production of internally clad metal containers, bottles and the like. Made of pipe pieces with a retracted bottle neck, in which; a plating forming inner container used and by air or liquid pressure to the Inside Nvand of the outer container to be plated is pressed after first the neck of the outer container. is made from one end of the pipe section, which is characterized by the fact that :, one of the open ground introduced, a shorter shape than the outer container and having a corrugated or groove-shaped shell part provided inner container firmly is tied to your neck of the outer container, whereupon after closing the bottom the plating container is stretched in a known manner and against the inner wall of the outer container is pressed.

In the drawing, the method according to the invention is shown on the basis of four Illustrations illustrated.

Fig. I shows the outer container body a with an initially forged Container neck h. After drilling the hole c is (the container with your sandblast cleaned. The thin-walled plating container d according to Fig. 2 of open bottom end of the main container pushed out into this. where the extended, appropriately threaded and the like provided neck e of the plating container the neck opening of the main container pushes through and with this through the nut / is screwed tight. It is preferably the end of the main container beforehand (r been heated in the oven. around to the bottom h with the extension i according to Fig.; deformed to become.

The thin-walled plating container is in its cylindrical part k wavy or similar in order to initially give it a shorter: shape, (so that it is as far away as possible from the area of the floor forging is a proper forging of the soil. without the you plating layer to damage, guaranteed.

Through the opening 1 in the extension i (Fig.,;) The new can now Scales and the like formed inside the room can be easily removed, and also through this opening enables the control of the entire floor piece inside. On that the bottom opening I is closed and welded with a plug n (Fig. 4.), O.

Through the neck extension p i Fig. 4) of the plating container now a suitable pressure medium, such as water, air or the like ... let into the container, whereby the Wellenfarin stretched out again, the container thereby stretched and in its entire extent to the flat concern .an the inner wall of the main container is brought.

The plating material can be any. according to the circumstances can be selected depending on the type of corrosion prevention.

The advantage over the known lies. in flawless manufacture an internally plated metal container with a small neck.

Claims (1)

Claim: Process for the production of internally plated metal containers, bottles and the like from pipe pieces with a retracted bottle neck, in which an inner container forming the plating is inserted and pressed against the inner wall of the outer container to be plated by means of air or liquid pressure, after first of all the neck of the outer container is made from your one end of the pipe section, characterized. that an inner container (% 1) which is introduced from the open bottom and which has a shorter shape than the outer container and has a corrugated or groove-shaped casing part ek) is firmly connected to the neck of the outer container (a), whereupon the bottom is closed (h) the plating container (d) is stretched in a known manner and atigeprel) t to the inner wall of the outer container.
