Description

DETAILED DESCRIPTION OF THE INVENTION 1. Water permeability The present invention comprises a side surface, a bottom portion and a top portion tightly coupled with the ends of the side surface, the top portion being provided with at least one filling hole, and the filling hole provided in the bottom portion. The present invention relates to a container having at least one stopper, the edge area of the hole being welded to the flange of the closure.

This type of stoppered container has a tightly coupled top and bottom and has a stability rating based on the described risk for this product when transporting and stocking liquids and other products. Used for liquids and other products that require expensive containers.

Generally speaking, the top of this type of stoppered container has two different diameters.
It has two flanges. These flanges can be tightly shut off by means of closure screws in conjunction with the seal. In this case a flange with a larger diameter (usually 2"
A smaller diameter flange (usually 3/4" wide) is used for filling, and a smaller diameter flange (usually 3/4" wide) is used to evacuate the container during filling and to introduce air when emptying the container. This type of flange has a male thread,
The packing can be tightly connected to the top by means of a tensioning nut. To reduce the considerable effort required for this, push-in flanges and welded flanges are used. Push-in flanges and welded flanges can be tightly press-fitted or welded into the upper base.For example, welded flanges are considerably cheaper to manufacture than threaded flanges and push-in flanges, and do not require packing rings, so they should be transported. This is advantageous when the product corrodes the material of the packing ring. However, the known welded seals also proved to be complicated to manufacture6, for example, not only was it necessary to punch out a suitable filling hole into the top, but also the edge of this filling hole protruded or rose above the surface of the top. The edge area may be folded.

Furthermore, the relatively wide mounting surface of this type of flange requires a large amount of material and is complicated to process by cutting and/or deforming. Clogged containers with flanges of this type have a high cost and are therefore only competitive in certain cases.

It is an object of the present invention that the stopper can be manufactured using a small amount of materials and with simple processing, that it can be easily and tightly fitted into the upper bottom of the container, and that the stopper does not protrude inward or has a small amount of damage. To provide a container with a stopper that does not protrude directly inward and can be manufactured at a low cost by reducing the manufacturing cost.

In order to achieve the above object, the present invention provides a pipe connection in which the flange is formed as a pipe connection having a thread for receiving a closure screw, and the inner end of the pipe connection is connected to the inner end of the pipe connection. It is characterized in that it passes through a break in the upper base that fits the end and is connected approximately flush with the upper base by a welded seam.

This type of flange can be manufactured from a section of the pipe, so it can be easily manufactured from commercially available pipe by simple deformation and cutting operations, and can be easily inserted into a simple opening punched out from the top bottom. It can be inserted securely and combined with this. Extrusion of specific areas of the upper base and/or folding of the edge area of the break is unnecessary. Also, since the tube connections are approximately in the same plane, there are no problems when emptying the container.

Advantageously, the inner end of the tube connection is reduced to a projection of decreasing thickness by means of an inclined flank. By adapting the thickness of the part of the pipe connection to the thickness of the top part in this way, not only problems during welding are eliminated, but also the sloped flank with reduced diameter
An inclined flank provided on the inner surface of the tube (which flank may optionally additionally be used as a predetermined joining surface for the part to facilitate positioning of the component for welding) Displacement during insertion and attachment of the connecting portion can be restricted. The welded seam joining the upper base and the tube connection can be designed as a grooved seam if the inner end of the tube connection is somewhat protruding.

A figure 7 seam guided along the seam is advantageous, especially if the inner end does not protrude or only slightly protrudes. In the case of a figure-7 seam, the arc discharge or the laser beam is guided approximately parallel to the axis or, with a slight inclination, along the formed seam.

A thread can be tapped or curled into the pipe connection which is provided to receive the threaded connection for tight closure. The weld seam can be produced by protective gas welding or by laser fusion welding. It is advantageous with respect to the mounting of the closing screw to be installed and its tightening if the outer free end of the tube connection is bent outwards and downwards, curled, folded or bent.

Daigansai Next, one embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a barrel with a stopper as an example of a container equipped with a plurality of stoppers. The sides 1 of the barrel with a stopper, which are provided with grooves for reinforcement, are connected to the bottom 2 or the top 3 on both sides.
is blocked by.

The bottom part 2 and the upper bottom part 3 are respectively connected to the ends of the side surface 1 by grooves provided around the side surface 1.

The upper base 3 is used to take out and put the contents of the container.
It is provided with two flanges 4.5 of two plugs of different sizes.

FIG. 2 is an enlarged view of a portion of the upper base 3, showing the flange 4 welded to the break in the upper base 3. The flange 4 has a pipe connection 6. The end of the tube connection 6 which is directed towards the inside of the container is configured in a stepped manner in the formation of an inclined flank 8 whose diameter decreases in the direction of the projection 7 . As can be seen from the cross-sectional view in the right half of FIG. 2, a portion of the tube is threaded 9. - As can be seen from the sectional view of the left half of the cylinder 2, a screw 10 can also be provided for receiving a closure screw (not shown). The upper free end 11 of said tube section is forced downwardly from its original position 11', shown in dash-dotted lines, ie rolled downwards, so that a relatively wide opening is formed for receiving the collar of the closure screw. The attached side has a surface.

The flange 4 is inserted by its protrusion 7 into a circular break in the upper base 3. The diameter of the break is selected such that the flange 4 is supported in place and attached to the upper surface of the upper base 3 by means of an inclined flank 8, so that the free end of the flange 4 is flush with the inner surface of the upper base. The protrusion 7 is selected to lie in a plane, or as shown in the drawing, to protrude very slightly beyond the inner surface of the upper base 3. Upper bottom part 3 to flange 4
A groove seam 12 is provided by welding in the angle formed between the side surface of the projection 7 of the tube part 6 and the underside of the edge region of the break in the upper base. This groove joint)′
, ] can be formed by conventional fusion welding methods such as, for example, protective gas welding or laser welding.

Advantageously, after inserting the two flanges 4 and 5 into the two filling holes, the upper base 3, which has been previously widened as described above, is tongued with the side surface 1 of the stoppered barrel.

The container according to the invention can be modified in various ways. A modification of this type will be explained with reference to FIG. 3, which, like FIG. 2, shows another embodiment of the flange 4.

A tube connection 6 is also used in this embodiment. The pipe connection 6 is provided with a screw 9 as shown in the right half of FIG.
Alternatively, the screw 10 shown in the left half of FIG. 3 is provided. The upper free end of the pipe connection 6 is deformed outwards, i.e. actually bent outwards by 180° as shown,
It forms a predetermined stop for the inserted occlusion screw.

In the left-hand half of FIG. 3, the inner free end of the tube connection 6 is not machined, so that the entire thickness of the tube connection 6 lies within the break in the upper base 6 that receives it. has been inserted into. The upper base and the pipe connection are the free end 1 of the pipe connection 6.
6 is located on the same plane as the inner surface of the upper base 3,
By suitably shaped and sized support elements,
For example, it is fixed by pressing for welding. Welded seam 17 that joins and seals the upper bottom and the pipe connection
is designed as a V-seam in this example. (2) At the seam, an arc discharge or laser beam is guided along the seam formed between the top base and the free end. In this case, the arc discharge or the laser beam can run parallel to the axis. However, since the heat conduction is non-uniform, it is advantageous to guide the arc discharge or the laser beam at a slight angle in the direction of the axis of the tube connection 6 with respect to the normal.

In the right half of FIG. 3, the free area of the tube connection 6 has been hollowed out somewhat. As a result, a protrusion with a larger inner width is formed. This projection is defined by an inclined flank 13 relative to the inner side of the tube connection 6. Due to welding, the pipe connection part 6 is fixed by a pressing member 18, only the extent of which is shown in the drawing. This hold-down member 18 can rest on the inclined flank 13. In this embodiment as well, even if the projection 14 projects slightly beyond the inner surface of the upper base 3, the weld seam 5, which corresponds to the weld seam 17 and is formed as a V-groove, provides the necessary tight and secure connection. .

The embodiments described above can not only be used in any combination, but also other variants are possible.

The invention provides a container with one or more closures that can be manufactured at relatively low costs.

The container flange according to the invention is easy to manufacture.

Easily, firmly and tightly with the top or bottom.

Moreover, the bonding can be performed reliably. It is also advantageous that the tube connections do not have to protrude inwardly, thus eliminating the problems that often occur when emptying the container. The invention is not limited to containers with a stopper, but also provides a variant that can be applied to any container that is to be provided with a stopper or multiple stoppers as the case may be.
