Drum with Enhanced Vacuum Full Description: Background of the invention The invention relates to a domed drum made of a thermoplastic synthetic material with a carrying collar enclosing the wall of the drum next to its upper end and having at least one bore neck in the rim area upper end This neck is recessed in the hole in such a way that the surface of the end of the neck of the hole is flush with the outer surface of the upper end or located slightly below it. Plastic barrels of this type are well known with at least one ring handle located at the upper circumferential edge. for the wall of the barrel; In addition to optional rolling collars around the perimeter of the drum. Plastic perforated drums can be manufactured in a variety of ways. In one possible way, the barrel is made

Cash by forming in a one-piece blow mold including the two ends of the barrel and the carrying and transport collars where the load and transport are compressed while still in the blow mold using movable mold slides (see German Patent 0 for example). In another way, the cylindrical body of the barrel and its ends 19174 are made by welding or gluing ae and the carrying and transport collars or rolling collars are preformed as independent parts and then assembled. Likewise, prefabrication is sometimes limited to collars (FFAEYEY) with glue (see, for example, the American patent Carrying and transportation alone as separate independent parts, then they are welded or glued together on the body of the barrel formed in the blowing mold.In a plastic barrel with another well-known hole, fix the upper end on the body of the Yo for disassembly (see, for example, the US patent SUE The barrel with a nut, where the carrying and transportation collar is an independent part, wide opening, equipped with a cover with a hole, sles. The plastic barrel can also be formed in the form of (£49 ETY) and with a clamping collar. Lil is adjustable, however, for all plastic barrels with a carrying collar And the upper transport, which is known to have a common defect, which is that, because the neck of the barrel hole or the house of the barrel hole is recessed at the upper end of the barrel, there is a problem in Ye emptying the remains of the contents such as these barrels. Even tilting the barrel has a door

- At an angle in an inverted position and swinging it by hand back and forth would at best lead to an unsatisfactory emptying of the remaining contents even if the barrel was placed so that the hole in the barrel occupies the lowest possible position. The present invention aims to find a structure for a plastic barrel with a dome or a structure for its upper end (lid) that allows the greatest possible discharge of the contents residues in a static tilting position (without swinging the barrel back (Ws 0). General description of the invention: This goal is achieved in the present invention with a barrel Plastic of the aforementioned type, where the upper end has a flat part with an essentially circular shape, or a symmetrical sloping part around the sides of the neck of the barrel bore. A point of the sloping part on the side of the body of the barrel next to the neck of the barrel hole and opens there on the lower level of the floor of the Bie the barrel hole or on the neck of the barrel mouthpiece.When emptying the residue or tilting the barrel at a slight angle in an inverted position inclined and still at an angle of 10 to ‎ 1" For example; the remaining liquid will flow on the Jalal surface of the part sloping to the wall of the barrel and up to the barrel borehole and then through the barrel borehole to the outside of the barrel, because the upper end 0 - is not flat but has a sloping part which is Vital in the invention near the barrel bore. In a preferred embodiment of the invention the sloping part forms with the remainder of the upper end of the barrel a ridge of slight inclination where it is equal to; its average distance from the axis of the barrel is a quarter of the diameter of the barrel or less; The borehole starts at or near the inclined edge on the side facing the middle of the barrel but has a greater inclination angle on the upper end than the sloping part of the circular part at the upper end of the neck of the 0 barrel. One of the most essential features is to retain as much of the original flat upper end area as possible; This is because a sloping part with a large surface area at the upper end would lead to a reduction in the support surface required for stacking the barrels and thus negatively affecting the properties of the barrel stacking. This form of the invention allows a bore barrel with a bore cap forming a bottom sealing device for the bore neck (sleeve) of the bore by recessing or sloping the bore house on the oriented side of the middle of the barrel at an angle Yo of between 0 and ©; degrees, and the best is approximately 50 degrees, and the sloping part of the circular part at the upper end is allowed to be at an angle of inclination between 01 degrees and VY degrees; And the best is about 17 degrees. In this perforated drum with a wide bore, emptying of the remaining contents occurs simply by tilting the drum and holding it Sle at an angle of 18 to ye degrees in an inverted position. yyy |

¢ In the AT embodiment of the invention of a barrel with a hole and a cover with a hole forming an upper seal at the edge of the neck of the hole of the barrel, it was taken into account that the sloping part of the circular part at the upper end be more flat or have an angle of inclination ranging from ; and 01 degrees; the best is about 6 degrees; A return or passage is also provided in the neck of the bore of the barrel with the upper sealing device on the side facing the wall of the barrel to drain the remaining liquid. In this barrel, emptying of the remaining contents occurs by tilting the barrel in an inverted position and keeping it tilted at a lesser angle ranging from approximately 10-17 degrees. Thanks to the construction of the upper end of the barrel or the cover of the barrel, the barrel conforming to this invention is suitable for independent emptying without retaining any liquid and without the need for manual rocking back and forth 0 provided that the barrel remains in its intended angular position; Mia using a dunn holding device and directing the barrel hole to be at the lowest position.

° blowing. The barrel has a cylindrical wall (YY) equipped with a collar (Vr) as a handle for the barrel located in the upper peripheral area and is intended for use with a barrel holding device. It has a flat upper end (VY). The upper edge of the barrel grip collar (71) protrudes from Surface of the top end of the barrel at a distance of about three times the thickness of the wall of the barrel (V£) lay in the upper end of the barrel (VY) adjacent to the wall of the barrel (YY) surrounding the barrel bore (VE) © neck (sleeve) A hole (V1) recessed in the barrel bore (VA) in such a way that the surface of the end of the neck of the hole (V1) is flush with the outer surface of the end of the barrel (VY) is recessed so that it is slightly deeper. tightly under the threads of the screws on the narrow sloping part of the diameter, and there is a flat part in the form of a segment of a circle or a part that is essentially flat and symmetrical (01) from the upper end (VY) symmetrically retracted with respect to the neck of the barrel bore (V3) or For the outer edge of the barrel Vo so that it extends at a small angle inward to the body of the barrel; and so that the lowest point of the sloping part (01) lies on the side of the barrel wall and opens there on the lower level of the floor (01) of the neck of the barrel bore in Same height as above. The reference number (YE) denotes a sloping edge that extends (in this example) as a straight line between the top end of the barrel (VY) and the sloping part (01). The Bie hole (VA) extends slightly to Beyond the slope of 0 (?7) in the direction of the axis of the barrel, the wall of the bore neck house is recessed at an angle (TA) of 0 to 0° and preferably approximately 500° to the upper end of the barrel (11) While the inclined part (01) which begins at the inclined edge (74) is inclined at an angle (37) between 01° and 17°, the best is approximately VY degrees on the upper barrel end (VF) abutting The sloping part (01) at its lowest point is the wall of the barrel from the inside at the height of the base area of the carrying and transport collar (70) or the area of its connection with the wall of the barrel (YY) (Ye). Figure (1). The barrel in its inverted position is inclined at an angle ranging from 18” to 10 degrees; it is kept stable in this inclined position, and it is preferable to use a suitable tilting device for this. Because of the difference in angles between the inclined part and the tilting angle The liquid contents can flow independently over the sloping part (01) to the wall of the barrel (YY) and from there out through the borehole or through the bore neck (V1) without leaving any residual Yo from the contents. 0 A figure (©) shows a different embodiment of a water limit where the borehole sink (VA) begins at the slope edge (;7) exactly on the side opposite the axis of the barrel; However, it recesses at an angle of inclination on the upper end of the barrel (VY) greater than the sloping part (01) of the circular part at the top of the barrel in the neck region of yyy

bore (V1) and in addition there is a rib-like (YE) protrusion in the floor (Yo) of the bore neck (Yo) between the barrel wall (YY) and the bore neck (13); With a depression (YY) Lilie stream-like (YY) on the inner surface. This ensures that the last remaining contents exit the drum through the recessed part between the sloping part (Ve) and the inner surface of the drum wall (YY) in the tilted position. Another difference lies in the fact that © the upper edge of the handle collar (701) is formed flush with the surface of the upper end of the barrel or at the same height. It can be seen how the sloping part (01) forms with the rest of the upper end of the barrel (VY) the slight sloping edge (YE), where the distance (176) between the mentioned edge and the barrel axis point (YA) is a quarter of the diameter. Barrel approximately or less. The borehole (VA) depression begins at the slope edge (YE) and the sloping part opens into the borehole side (01) on the flat floor (01) of the borehole (VA ) The relatively narrow rib-like protrusion (VE) extends between the surface of the inner wall of the barrel (YY) and the neck of the barrel bore (071). Figure (0) illustrates the flow chart of the last remaining drops of liquid content. Accordingly, the liquid residue flows from The inner surface of the upper end (VY) in a direction substantially perpendicular to the slope edge (Y£) 1 to the arched inner wall of the barrel (YY) and then along this surface to the bore in the borehole floor area.) 71) From this final assembly point the last liquid LED flows through the short, slightly recessed channel (37) extending radially to the neck of the hole (V1) and out of the barrel. There is another modification to enhance the speed of flow of the last residue of the remaining liquid, according to what is shown in Figure (7) in the lower diagonal line (01), which is that the two halves of the sloping part (aie (01) seen in the inverted 0 position) are inclined inclined slightly on each other and then extend downward in the direction of the hole, i.e. they enclose between them a total internal angle equal to approximately 175 degrees at the neck of the hole (the line connecting the center of the hole (V8) and the center of the barrel (YA) and illustrates Figure ) 1) Another blow molded plastic barrel with a different hole Bie (44). In the neck of this hole (££) the threaded cap of the hole (not shown in the drawing) closes the barrel tightly by means of a Y-seal fitting at the The upper end or the edge with a lip of the neck of the hole, unlike what is the case in the barrel shown in Figure (1), in which the cover of the hole of the barrel is closed tightly by means of a masked sealant in the lower part of the bore somewhat of Bie the hole (V1 ) and in this embodiment a setback (£7) may form on the inner or lower side of the bore neck (£2) facing the wall of the barrel (YY) and through this setback Yyy

l (£1) The accumulated residual liquid can flow out of the barrel while it is in the residue discharge position or the inverted inclined position. With this additional measure, providing a backflow (7£) at the lower edge of the borehole as shown in part in Figure (1a); It is sufficient for the sloping part (£0) of the circular part at the upper end of the barrel to have a slight inclination angle (47) between 01 and approx, and to lead at its lower point © to the area of the conical return edge of the upper end of the barrel (VY) At mid-height of the long vertical leg of the carrying collar (Vo) and such that a reflux (7;) or groove (00) Bie (44; 4) is provided on the side opposite the barrel wall (YY) for Drainage of residual liquid Figure (V) shows an embodiment of an injection molded barrel cap with a cylindrical dovetail neck (EA) The upper end of the barrel in this embodiment is formed in the same manner as the barrel shown in Figure (1) except Ve The borehole (EA) is located lower in the borehole (VA) and protrudes slightly to cpa Jada. This bore neck (48) is closed securely at its upper end with a tapped bore cap (not shown in the drawing). . In order for the AT to be able to remove the accumulated residual liquid from the barrel unhindered, the Bie hole (48) was provided with a corresponding channel (901) in its side facing the wall of the barrel (YY). Hole (8;) as a section in Figure (IV) and as a profile in Figure (QV) for illustration. Achieving it in the form of a fully one-piece plastic barrel by making the bore taper alone in an injection mold and then welding it in the right place with the floor of the bore house. Yo The short drain stream (YY) (see Fig. 0) extending from the barrel rim into the bore may be discharged at a higher level point in the borehole; however, complete and independent emptying of the contents remains. Supplementary drawings provide further illustration of the shape The upper end of the barrel according to the present invention: Figure (A): Another embodiment of the upper end of the barrel (the barrel cover) according to the invention. Figure (4): An embodiment of the AT according to the invention in the form of a partial perspective drawing. Figure (01): Al embodiment according to the invention in the form of a complete perspective drawing. In the horizontal projection of the upper end of the barrel as shown in Figure (A), the sloping edge extends between the upper end of the barrel and the sloping part in a manner that is not completely straight. Instead it extends both halves of the sloping part Yr

- A are inclined at a slight angle between them at the edge of the slope. Likewise, the two halves of the surface of the sloping part can be inclined towards each other at a slight angle with an inclination at the barrel hole in the inverted position to enhance the discharge of the remaining liquid. . JS Gy cover in this and other embodiments; that is, by combining several features according to the invention; An ordinary standard ° can also be made in a similar way and fixed to the upper opening of a barrel open from the top by means of a clamping collar. iia In the partial perspective drawing shown in Figure (3), the sloping edge of the sloping part is formed on a scythe or an arc, where no The surface of the two halves of the sloping part shall be flat, or even curved, with a slight curvature towards the outside. Two bodies of barrels with their bottoms at the same time in a blow mold, then they are separated at JU in this technique in the middle, then an upper end of the barrel is welded on each body, including the outer handle collar, and it is previously manufactured in an injection mold. To form an iad edge and fall within the scope of this invention all the combinations of the features shown above. Vo in the form of an arc of a circle (VY) and the remainder of the upper end of the barrel (01) between the sloped part (YE) slope (01) having a large radius or being curved in the shape of a sickle, provided that the sloping part is increased or decreased in the areas of the outer edges. These measures of the invention are also suitable for the production of a barrel with a stopper manufactured from one piece in a blow mold with a collar An upper handle is attached to it by pressing or to produce a barrel consisting of assembling its various prefabricated individual parts (the upper end of the barrel with the handle collar, the base of the barrel and the cylindrical wall) together by welding or gluing. It is also possible to form the barrel in the form of a barrel with a lid (a wide-opening barrel) with a plastic cover or a steel plate that can be tightly attached to the barrel with a clamp, provided that the cover meets the features of the invention. When plastic barrels are stacked for long periods of time, it is possible That the upper end of the barrels located below the stacking occurs a slight drop to the bottom towards the inside of the barrel as a result of the stacking decrease. In the usual plastic Yo barrels with the upper end convex towards the outside, the possibility of emptying the contents residues is negatively affected, while this phenomenon does not reduce the possibility of emptying the contents residues in the plastic barrels according to this invention, but rather is beneficial for them instead.
