Description

The invention relates to a barrel with a stopper intended for the storage and transport of liquids made of thermoplastic plastic material located in the adjacent section of the upper bottom on the wall of the barrel, bypassing the transport and transport ring and with at least one located in the boundary section at the upper bottom, an orifice which is embedded in a separate body of the orifice in such a way that the front surface of the orifice is closed on a plane with the outer surface of the upper bottom or slightly below it.

Plastic barrels with at least one located on the upper peripheral portion of the barrel housing, a clamping ring intended for stacking barrels, and optionally additional rings for rolling around the barrel circumference are known. Plastic barrels with plugs can be made using different technologies. In one embodiment, the barrel is molded monolithically with bottoms and rings for carrying and transport by the inflating method, with the bearing and transport rings being stuffed further in the inflating form by moving sliders of the form / 1 /.

There are known barrels, made according to another embodiment, in which the cylindrical body of the barrel and the bottoms with rings for carrying and transport, respectively. Rolling rings are made separately in advance as single parts, after which they are welded or glued to each other / 2 /.

Also known are barrels made by prefabricating only wear and transport rings as separate single parts, after which they are welded or glued to the barrel body made by blow molding.

In another known plastic barrel with a plug, the upper bottom with the carrying and transport ring is screwed as a detachable separate part to the barrel wall / 3 /. The plastic barrel can also be made as a wide-necked vessel, with an opening opening cap and a clamping ring.

All known plastic barrels with upper bearing and transport rings have the common disadvantage that, due to their incorporation at the hole of the opening, respectively. of the opening body in the upper bottom of the barrel, problems arise when the barrels are not emptied enough. Even by manually shaking the barrel back and forth in an upside-down position, only an unsatisfactory drainage of the residue is achieved, even when the barrel is held in a position where the opening is at the lowest possible position.

Another plastic barrel with a stopper is known, in which for the final release from a possible residue when emptying the barrel in ordinary inclination positions, the stopper is mounted near the wall of the vessel. To avoid inconvenience at work and loss of emptying, the opening of the plug is located in a trough. The plug thus made, in comparison with the lateral plug externally on the barrel wall, is protected from undesirable force.

Due to the elasticity of the barrel, a raised area is formed in the area around the plug opening. For ordinary barrels, the plug opening is made on the barrel wall and the wall in this area is weakened. But for this famous barrel on its inside is provided a separately shaped crease, located between the opening for the stopper and the bevel transition. Another larger size plug is located in a recess. In this way, the threshold thus created can create a quiet current for the last phase when emptying the remainder of the material (in the recess area). This does not result in loss of time during the entire emptying process / 4 /.

It is an object of the invention to provide a structural layout of a plastic barrel with a stopper or respectively. on the top bottom (lid) to allow the maximum possible emptying of the rest of the contents in a static tilted position without shaking back and forth.

According to the invention, the problem is solved with a plastic barrel of the type described in the introductory part, the upper bottom of which has a part of the surface with an approximate shape of a circular segment, respectively. a flat bevel, which part is made on both sides symmetrical to the mouth of the opening and viewed in normal position of the barrel, is drawn obliquely inwards into the body of the barrel and is inclined in the direction of the edge of the barrel. The lowest bevel point is on the side of the barrel housing adjacent to the mouth of the opening and there it flows into a plane lower than the bottom of the body of the hole of the opening, respectively. at the neck of the plug hole. Since the top bottom is not completely flat and there is a substantial slant in the area of the invention when pouring out the residual liquid or respectively. when positioned in a pouring position in a slightly inclined or stable oblique position of the barrel at an angle of about 10 to 12 °, the residual fluid flows down the inside of the flat portion from the barrel wall to the body of the opening neck and then through the neck out.

In a preferred embodiment of the invention, it is provided that the bevel, together with the rest of the barrel bottom, forms a boundary edge whose average distance from the center of the barrel is approximately equal to or less than a quarter of the barrel diameter, such as the location of the wall of the body of the neck of the opening to start from the pointing towards the center of the barrel on the border edge, respectively. adjacent to it, but to have a greater angle of inclination with respect to the upper bottom than the bevelling of the circular sector of the upper bottom in the area of the mouth of the opening. The important thing here is that there should be as large a section as possible from the original flat section from the top bottom, since chamfering the top bottom over too large a surface would reduce the support surface when stacking the barrels and hence impair the barrel's ability for stacking.

In carrying out the invention for modification of a barrel with a stopper, it is provided that, with the opening of the opening closing the lower opening of the opening, the location of the wall of the body of the opening of the opening shall be inclined towards the center of the barrel at an angle of from 30 to 45 °. , preferably about 40 °, and the bevel of the circular sector from the top bottom is at an angle of 10 to 17 °, preferably about 13 °. In this barrel with a plug, residual emptying occurs through the extended neck by a conventional inclination and holding in an inclined position at an inclination angle of 18 ° to about 20 ° in the oblique position of the barrel. In a further modification of the barrel according to the invention and with the lid of the plug sealed above at the edge of the mouth of the opening, it is provided that the beveling of the circular sector from the upper bottom is more gentle, respectively. there should be an acute inclination angle of between 4 and 10 °, preferably about 6 °, and a cut-out, respectively, is made in the upper side of the orifice, which is directed towards the housing of the barrel, with a view to the leakage of residual fluid. window. In this barrel, residual fluid drainage is therefore by tilting and holding it at a smaller angle of about 10 to 12 ° in the slightly oblique position of the barrel.

The structural design of the barrel according to the invention, in particular at the top bottom, respectively. with a suitable barrel lid, allowing self-pouring without residue and without tilting by hand, under the conditions provided, for example, by means of a suitable conventional fastening device, the barrel remains in the intended inclined position and the opening must be made at the lowest place .

Figure 1 shows a stackable thermoplastic barrel for maximum emptying of residual fluid prepared by the molding method by blowing a monolithically packed engagement ring. The barrel has a cylindrical casing 22 with a ring 30 in the upper circumference of the circumference of the barrel stacking and a flat top bottom 12. In this case, the upper edge of the engagement ring 30 rises approximately three times the wall thickness beyond the surface of the upper bottom. In the upper bottom 12 of the barrel, a hole 14 for a plug is made near the housing 22. The opening 14 is enclosed by a neck 16 which is embedded in a body 18 of the neck 16 of the hole 14 in such a way that the front surface of the neck 16 closes approximately in a plane with the outer surface of the upper bottom 12 or is lowered slightly lower . The hole of the opening is sealed under the thread on the oblique narrowing of the diameter.

Part of the area of the upper bottom is circular shaped, respectively. a plane or flat bevel 10 at the top bottom 12 is drawn symmetrically in the direction of the neck 16 or respectively. to the outer edge of the barrel, slanting inwards into the body of the barrel, inclined with a bevel 10, whose lowest point is on the side of the barrel 22 of the barrel, where it flows into the plane of the lower plane at the bottom 20 of the barrel. the body 18 of the neck 16 of the opening 14.

Position 24 indicates the boundary edge between the upper bottom 12 of the barrel and the bevel 10. The arrangement of the body 18 of the neck 16 of the hole 14 for the plug is thus shifted slightly beyond the border edge 24 towards the center of the barrel. This wall of the body of the neck 18 is inclined at an angle 38, the values of which are between 30 and 45 °, preferably about 40 °, relative to the upper bottom 12, while starting at the boundary edge 24 bevel 10 is at an angle 36 of magnitude between 10 and 17 °, preferably about 13 °, relative to the upper bottom 12 of the barrel. The bevel 10 borders at its lowest point with the height of the support zone of the bearing and transport ring 30, respectively. to its junction with the housing of the barrel 22 on the inside of the housing.

The position of complete pouring of the barrel with a stopper is shown in Figure 2. For this purpose, the barrel in an upright position tilts at an angle of about 18 to 20 ° and is held in this inclined position at rest, for example by a suitable tilting device. Due to the angle of inclination, the fluid medium can flow down the bevel 10 to the barrel 22 and then through the body of the stopper or respectively. through the neck 16 independently flow without residue.

Figure 3 shows a modified embodiment. Here, the inclination of the body 18 of the neck of the hole 14 on the side facing the middle of the barrel starts right from the border edge 24, but this slope has a greater angle with respect to the upper bottom 12 than the bevel 10 of the circular sector from the upper bottom in the neck region 16. In addition, a rib-shaped projection 34 is provided between the barrel 22 of the barrel and the neck 16 of the hole 14 at the bottom 20 of the neck 16, with a groove 32 corresponding to the inner side thereof. Output of the barrel without residue flows out of the gap between the chamfer 10 and the inner wall 22 of the barrel. In addition, the upper edge of the engagement ring 30 is located at the level of the outer surface of the upper bottom of the barrel 12.

Figure 4 shows from the top view the most substantial part of the upper bottom of the barrel 12. From this it can be seen that the bevel 10 forms with the rest of the upper bottom 12 the boundary edge 24, the distance 26 of which from the center 28 of the barrel is approximately equal or less than a quarter of the diameter of the barrel. From the boundary edge 24 begins the body 18 of the neck 16 of the hole 14. The bevel 10 on the side of the hole 14 gradually passes into the plane of the bottom 20 of the body 18 of the neck 16. Between the inner wall 22 of the barrel and the neck 16 is a relatively small rib projection. 34.

The flow diagram of the residual fluid droplets is shown in Figure 5. According to it, the fluid residues flow from the inner surface of the upper bottom 12 at right angles through the boundary edge 24 to the inner convex wall 22 of the barrel and then to the recess 32 in the area at the bottom 20 of the body 18 of the neck 16 of the opening 14. From this collection point, the last fluid residues flow through the short, passing through the radius of the recess 32 into the hole 16, respectively. run out of the barrel.

Another modification to accelerate the rate of leakage of the last fluid residues is that (Fig. 3) through the base of the bevel 10, the two bevel halves 10 at an inclined barrel pouring position are slightly inclined toward each other with decreasing direction of the hole 14, i. between them at the neck 16 (centerline through the hole 14 and the center of the barrel 28), an internal total angle of about 175 ° is made.

Figure 6 depicts another embodiment of a plastic barrel made by blow molding with a different neck 44. With this other neck 44, the screw cap of the opening (not shown) is sealed by a corresponding seal against the top edge or respectively. the flanged edge of the neck, opposite to the barrel shown in FIG. 1, in which the cap of the opening is sealed with a seal in the lower, slightly recessed neck 16. Thus, in this embodiment, on the barrel-facing side 22 of the inner, resp. the lower part of the other neck 44 may be formed by a cutout 46 through which, in the final emptying position, respectively. inclined barrel position, any leaking fluid may leak out. By this additional measure, with a cutout 46 on the lower edge of the neck, as shown in the partial image and in Figure 6a, it is sufficient that the other bevel 40 of the circular sector from the upper bottom has an angle of inclination 42, with a magnitude between 4 and 10 °. preferably about 6 °, and at its lowest point about half the height measured from the outer edge of the carrier and transport rings 30 to flow into an inclined, conically drawn area from the edge of the upper bottom 12 of the barrel, wherein in the other neck 44 is directed and the wall 22 of the drum side is provided a recess 46, respectively. window 50 for leakage of residual liquid.

Figure 7 shows a pressure-molded barrel with a cylindrical inner neck 48. In this case, the upper bottom of the barrel is made in the same manner as in the barrel shown in Figure 6, only a half-hidden neck 48 is embedded in the barrel. deep into the body 18 of the neck 48, respectively. it enters slightly inside the barrel, since this half-hidden neck 48 is sealed to the upper edge by a (not shown) screwed hole cap. In order for the last flowing fluid to flow freely here, this inner neck 48 on the barrel-facing housing 22 has a corresponding window 50. The window 50 in the half-closed neck 48 is shown in Figure 7a in cross-section, and in Figure 7b - side view to illustrate the positions.

This arrangement of the upper bottom of the barrel, which is made by the method of injection molding and welded with a molded example by blowing the casing with the bottom, can also be implemented by the method of blowing for a completely monolithic plastic barrel with only half-hidden The neck 48 of the hole is pre-fabricated as a separate injection molded part and welded at the appropriate place at the bottom of the neck body.

In the embodiments of FIGS. 6 and 7, in which the plug is provided with a seal lying on top, the short outlet recess 32 (FIG. 5) may extend from the edge of the barrel into the opening higher in the body, which despite this is achieved on its own, complete drainage of residual fluid.

For better illustration of the upper bottom of the barrel, the following figures are attached, of which:

Figure 8 is another exemplary embodiment of a barrel top lid according to the invention;

Figure 9 is another embodiment of the invention in partial axonometric view;

Figure 10 is a recent embodiment of the invention in general in axonometry.

When viewed from above on the upper bottom 12 of the barrel according to Figure 8, the boundary edge 24 between the upper bottom 12 of the barrel and the bevel does not extend completely horizontally, and the two bevel halves pass at the border edge slightly inclined towards each other, with a fall to the opening at positioning of the barrel in the pouring position to facilitate the escape of residual fluid.

In this case, it should be noted that the smallest of the two plugs serves as a drain plug and is located within the bevel.

In this or any other embodiment, respectively. by combining several of the features of the invention, however, it may at the same time be a conventional standard cover, which is secured by means of a clamp with a clamping ring to the upper opening of a wide-necked barrel (Open Top Drum).

In the partial axonometric view of FIG. 9, the cutting edge is inclined in the shape of a sickle, respectively. an arc where the two halves of the bevel plane may not be planar but also projected outwards.

Figure 10 is a general perspective view of an embodiment of a barrel according to the invention, which is particularly suitable for tandem blow molding.

In this case, two bodies of barrels with bottom bottoms are simultaneously blown into one shape, then cut and split in the middle and onto each precursor, ie. on the bodies of the barrels one welded upper bottom with an external transport ring prepared in advance by the injection molding method.

All arbitrary combinations of the features shown are within the scope of the invention. For example, the boundary edge 24 between the bevel 10 and the rest of the upper bottom 12 of the barrel may be made - by increasing or decreasing the bevel 10 in the outer portions of the edge, in the form of an arc of large radius or sickle shape. The technical features according to the invention are equally suitable for a monolithic blow molded barrel with a stuffed engagement ring of a barrel or for welded or glued by prefabricated separate parts (upper bottom of barrel with engagement ring, lower bottom of barrel and cylindrical wall). The barrel may also be formed by a lid (wide-necked vessel) with a clamping ring on it made of plastic or sheet steel, in which case the lid has the features of the invention.

Continuous stacking of plastic barrels may cause the top bottom of the barrel to slightly drop downwards, towards the inside of the barrel, under the influence of the stack load. In conventional plastic barrels with an outwardly blown upper bottom, the possibility of complete emptying is thus reduced, while in the plastic barrel according to the invention this phenomenon does not limit the possibility of final emptying, but rather increases it.
