Description

TONEL OR BARREL COM CYLINDRICAL COVER FORMED BY BLOWING DESCRIPTION OF THE INVENTION The present invention relates to a barrel or barrel provided with a cylindrical shaped lid manufactured by blowing, being a wide neck container with barrel cover and ring type closure of tension where the ring with a "U" cross section grasps in the closed state with its upper arm the upper edge of the lid and with its lower arm grasps underneath a basically horizontal barrel edge or with a trajectory directed slightly downwards , in the area of the mouth of the body of the barrel. The barrel of this type has been known, for example, from DE-B-41 08 606. However, in the case of this barrel, the tension closing ring is located at a certain distance below the upper edge of the barrel. lid or the opening of the barrel, which only allows the handling of a barrel with lid of for example 220 liters of loaded capacity corresponding to this type with a transport weight of around 230 kg with special gripping tools. This type of barrel with lid was developed by the company Mauser in 1975 and is known worldwide under the name "barrel with standardized layer" and is very suitable for the application of particulate fillers or pasty, but for the use of products liquids is not quite suitable a barrel of this type.

REF: 24214 In barrels fitted with lids, the hermetic effect of the barrel lid on the barrel opening is achieved by axial prestressing applied to the cap seal through the inclined arms of the tension ring on the upper edge of the barrel. cap and on the edge (or depression) of the barrel body during the closing of the tension ring. In those barrels with lids accepted for example in the chemical industry, certain requirements have been established regarding their storage and transport safety, which are tested by special acceptance tests (for example, the lateral fall or fall on the mantle, fall diagonal on the edge of the lid, test of the static internal pressure and other tests). In the barrels or barrels with plastic caps are produced in the falls from heights of about 1.20 - as for example from the loading platform of a truck - leaks from the aforementioned barrel, especially in the case of liquid products, or even a complete detachment of the barrel cover. The disadvantages of the casks with lid known to date are mainly the following: a) in the case of an axial internal pressure on the cask lid (pressure hit in the case of a fall on the mantle of a barrel filled with water in the case of the internal hydraulic pressure of a closed barrel) b) in the fall of a closed barrel filled with water in a flat form on the side wall (falling on the mantle) and c) during the fall of a closed barrel filled with water diagonally on the edge of the lid different reactions occur: - the lid of the barrel is pressed axially outward; - the tension ring is stretched axially outwards; - the tension ring (together with the cover and the mouth area of the barrel) is flattened at the central point of impact of the blow; - the tension ring buckles laterally with respect to the point of impact in both buckling or breaking points its "U" shape is opened; - the edge of the cover tries to exit under the arm of the tension ring; - the prestressing of the seal or packing is reduced and the closing system presents leaks. The stresses produced during the deformation have to be received in all cases by the voltage ring with a "U" shape. Here the arms in the buckling or breaking zone are pressed to the outer side (they expand). If the solicitations applied to the arms are too high, then they produce permanent deformations, reducing the prestressing of the seal in said areas and the greater expansion produces leakage or leakage of the barrel. It is therefore sought to reduce the deformation of the tension ring, especially the expansion in the "U" zone by means of constructive measures, especially in the area of the opening or the mouth of the barrel, in the lid of the barrel and / or the ring of tension, while preserving the possibility of good handling, ie a simple closing of the tension ring. The object of the present invention is to deliver a barrel with a plastic lid provided with a barrel lid and a tension ring closure, which by means of the special adjustment of the individual components allow the same gripping tool to be used. ("parrot's beak") or when it is loaded, it can be handled with the gripping tool, as is usual, and it is done in barrels with a plastic L-ring type layer or in the case of drums with a lid of steel. The barrel with lid should be particularly suitable for receiving liquid transportable products, ie in the case of falls from major and important heights still remain liquid-tight. According to the invention this objective has been achieved by means of a design in which: the barrel cover is immediately behind the edge of the outer cover, grasped by the upper arm of the tension ring closure, which in a view in FIG. cross-section presents a downward-facing "U" shape, in which the seal of the cap or this foamed element is placed, a perimetral "V" gripping groove collected downwards in the barrel body, with a bottom of flat slot, between a central cover disk with a reduced diameter and the edge of the lid; - the constraint of the gripping groove by an annular part located in an obliquely upwardly conical shape, followed by the disc of the flat lid with at least one barrel hole located laterally in the housing of the hole, sunk therein; the lower arm of the closure by means of a tension ring grasps at a discharge in the upper wall of the barrel a little below (approximately 15 mm) from the upper edge of the barrel, whose upper limit basically constitutes the barrel edge following an essentially horizontal path, or slightly oblique of the bearing surface for the tension ring and whose downward transition to the fully cylindrical part of the barrel wall is basically tapered and flat increased, where the transition from the conical zone to the fully cylindrical part of the barrel body it is located at a distance of 80 mm to 140 mm, preferably around 120 mm, from the upper edge and front edge of the opening of the barrel, and where the upper edge of the barrel of the barrel opening is designed in solid form by way of an opposite support for, a seal of the lid and has a width (thickness) equal to at least twice the thickness of the body wall of the nel By means of the special configuration of the invention of the upper outer zone of the barrel with lid, it is allowed, on the one hand, the use or application of the usual clamping and gripping tools in the barrels with opening, and on the other hand the barrel With lid according to the invention, it also has an improved liquid tightness when filled with liquid products, such as, for example, in the case of falls of the barrel from greater heights (about 1.8) or in the case of the certification or acceptance tests described above. In a variant of the design according to the invention, it has been considered that the transition or conical trajectory of the wall of the barrel within the outlet and below the horizontal support surface for the lower arm of the closure by means of the tension ring until passing to the completely cylindrical part of the barrel body, occurs at an acute angle between 15 ° and 30", preferably around 18 ° to 20 °, with respect to the longitudinal axis of the barrel.Thus it is possible to first bring the conventional bra first to the body first of the barrel and then upwards until removal or retraction, until the bottom clamp of the barrel clamp touches the horizontal support surface of the arm that rests on the edge of the barrel of the tension ring and due to the strength of the barrel. It produces the automatic lowering and screwing of the upper clamp of the barrel holder, allowing to secure and transport the barrel with lid in a safe way. In order to ensure a secure seat of the lower arm of the tension ring, as well as of the clamp of the barrel fastener that fits in said place, it has been arranged according to the present invention that the radial depth of the depression, measured from the extension line of the completely cylindrical part of the barrel body is between 12 mm and 25 mm, preferably around 17 mm. Here the edge of the barrel with a slightly oblique trajectory, which serves as a support surface for the lower arm of the tension ring and which at the same time constitutes the upper limit of said depression, is placed at a distance of about 10 mm up to 20 mm, preferably about 15 mm from the upper edge of the barrel at the outer edge of the barrel body. On the other hand, an opposite support is also obtained for the tension ring as well as for the fastener of the barrel applied, by means of the design of an edge of the opening of the barrel with its smooth semi-circular area directed upwards, which serves as a sealing surface For the seal of the lid, it is manufactured during the blowing process by upsetting the thermoplastic material of the barrel wall with the help of valves incorporated in the matrix, whereby at the bottom of the solid edge of the barrel an edge has been formed type flange, perimeter, radially away, with a radial extension of around 3 mp >; up to 5 mm, which increases the width of the horizontal support surface for the lower arm of the tension ring. Because the barrel with lid according to the invention has in its lightweight mode (with a capacity of 35 US gallons (132.5 liters) only a barrel body weight of about 5.2 kg and for a capacity of 55 gallons (208.2 liters) only a barrel body weight of about 8.2 kg, as well as a 15% larger opening of the barrel's upper mouth compared to the conventional domed barrel of the mentioned type at the beginning, it is particularly suitable for the transport of granulated or pasty products, for which fiber drums are currently used, and fiber drums are frequently used in the USA, provided with an inner coating for packaging liquid products thanks to their excellent hermetic properties for gases and liquids, as well as its characteristics of complete residual emptying (with the lid installed) through the opening with lid for final emptying, the cassette with lightweight construction according to the invention can be used in place of conventional fiber drums up to now, also for preserving liquid products. Other advantages of the barrel with lid of the invention reside in the fact that they basically have the same measures as the corresponding barrel with opening of plastic material with ring type "L" or the drum with steel opening so it can be handled with the same fastening tools for barrels ("parrot beak" = parrot beak). These lidded barrels can also be palletized with the drums without the usual space losses due to the bulging casks and differentiated heights. Covered barrels can be loaded through a 2-inch orifice (approximately 5 cm) in the same loading facilities as drums with holes, since the dimensions and the hole arrangement of the lid correspond exactly to the relevant measurements of the drum with hole. The reconditioning of the barrels with lid for reuse or for and being used several times is considerably simpler in comparison with the drums with opening or orifice and is more efficient and a final disposal does not present problems, because the plastic material coming from the The body of the barrel and the lid of the barrel, as well as the tension ring, whether made of steel or plastic, can be completely recycled. The invention will now be explained and described in detail as well as other design variants through exemplary embodiments shown schematically in the drawings, in which the following is set forth: Figure 1 shows a cask with lid of the invention with foot ring in a profile view; Figure 2 is another embodiment of the barrel with lid of the invention; Figure 3 is a comparison of the configurations between the usual domed barrel and the cylindrical barrel of the invention; Figure 4 is a sectional view through the left edge area of a barrel with lid according to the invention (US version); Figure 5 is a sectional view through the left upper edge region of a barrel with lid of the invention; Figure 6 is a sectional representation of the upper right edge area of a barrel with lid according to the invention with the clamp jaws applied;Figure 7 is an enlarged sectional view through the right upper edge area of a barrel with lid according to the invention; Figure 8 shows another cask with lid according to the invention (without foot ring) according to a profile view with a partial cut representation (version of Europe); Figure 9 is an enlarged representation of the upper zone of the barrel with lid according to Figure 8; Figure 10 shows the upper zone of the barrel according to a representation in partial section; Figure 11 shows the upper zone of the barrel according to Figure 10 according to a view in full section; Figure 12 shows the upper zone of the barrel in a sectional view; Figure 13 shows the upper left zone according to a sectional view of another barrel mode (US version, and Figure 14 shows the upper left zone of the barrel according to a section representation of another barrel type ( US version.) DETAILED DESCRIPTION OF THE INVENTION In FIG. 1, a barrel with lid according to the invention with a capacity of 55 US gallons (208.2 liters) equipped with a barrel cover has been identified with reference 10. 12 and a closure by a tension ring 14. Approximately 80% of the barrel body 20 has a completely cylindrical shape, while each 10% of the barrel height up to the opening edge of barrel 28 and below until the bottom of the barrel 34 is gathered according to a slightly conical shape, in the completely cylindrical part 26 of the body of the barrel 20 a third and two thirds of the barrel height have been formed two rings of conduct ura 38 of the barrel body rounded and comparatively wide. In the conical pick-up transition zone between the completely cylindrical part 26 of the barrel body 20 and the lower flat bottom of the barrel 34, a solid-bottomed rolling ring 36 is arranged, which closes aligned or abutting with the bottom bottom of the barrel 34. The bottom running ring 36 has a trapezoidal cross-section with a thinner connecting web in the body of the barrel 20 and an outer diameter substantially the same as the closing ring and thus gives the barrel with stop 10 an excellent resistance in the vertical position, especially when stacking several barrels one on top of the other, and one, high rigidity or resistance to impact or crushing (moving work on the plastic material) of the lower edge of the barrel during the inclined rolling of a barrel with lid loaded. The barrel with a capacity of 55 US gallons (208.2 lt) has a larger diameter of about 578 mm and a height of about 898 rr.ra (height / diameter ratio of about 1.55). A first modified embodiment of the barrel with the same dimensions of diameters, but with a high capacity of less than 52.5 gallons (19915) has a height / diameter ratio of about 1.49, where the height of the barrel with the ring of tension placed is around 860 mm. So this barrel has exactly the same height as the usual lidded barrels in the US and so you can palletize with them. Another modified embodiment of the barrel with the same dimensions of diameters, but with a comparatively smaller load volume of only 36 gallons (136.3 lt) has a height / diameter ratio of just 1.06, the height of the barrel being The installed voltage ring of around 610 mm. This barrel or drum (the so-called "Stubly Drum") looks as high as wide and has been considered in a special way to package granulated or powdered products, such as for example color pigments, where to extract the dye pigments from the drum these are extracted manually with a spoon or pallet. Due to the reduced height (approximately the length of the arm) of the barrel it is also possible to extract small quantities from the lower area of the barrel, without the need to hang inside the barrel and have to suck up dust particles.

A preferred example of a barrel with a stylized lid 10 with a capacity of 35 gallons (132.5 15) is shown in Figure 2. The height / diameter ratio of this barrel is around 1.82. A modified design modality with identical diameter dimensions, but with a capacity of less than 30 gallons (113.6 lt) presents, contrary to the previous case, a height / diameter ratio of around 1.57, where the height of the barrel with the tension ring installed amounts to about 745 mm. The two types of casks having the same diameter (according to Figures 1 and 2) with only different heights can be conveniently manufactured in a single interchangeable blow mold. For this it is only necessary to introduce a corresponding annular piece of extension in the blow mold (in the case of the barrel of greater height) or this piece should be removed (in the case of the barrel of lower height). The special characteristic of these design modalities is that these barrels have practically the same dimensions as those of the usual fiber drums in the USA and they can be handled with the same gripping tools as the drums with holes or the barrels of conventional fibers. . The new lid casks in a light construction can also be manufactured more economically than the comparative fiber drums and later do not generate disposal problems, because they are totally recyclable. The tension ring can be a steel plate closing ring, but it can also be made entirely of plastic material.

In the case of a reuse of the barrel with lid according to the invention for liquid products the lid of the barrel 12 is provided with at least one opening for loading and emptying, preferably with two lateral openings that can be closed in opposite positions, where the opening The larger 42 can have a 2-inch hole (about 50.8 mm) and the smaller opening 44 can have a 3/4 inch hole (about 19.1 mm). In Figure 2 it is also seen that the conical trajectory of the barrel wall within the retraction 22 below the horizontal support surface 18 passes the lower arm of the tension ring closure 14 to the passage 24 to the fully cylindrical part 26 of the barrel body 20 forms an acute angle between 15 ° and 30 °, preferably of about 18 ° to 20 °. This configuration allows to achieve high rigidity in the case of stacking loads. In Figure 3 there is shown in the left half of the dotted line drawing a barrel with a standardized domed lid of the prior art or a barrel body 46 in comparison with the barrel body 20 of the invention 20. From here it is clear that stability of the barrel with the slender lid of the invention. On the other hand it is observed that in the case of the body of the domed barrel the completely cylindrical part only comprises about a third / 1/3) of the total height of the body of the barrel. while the completely cylindrical part 26 of the body of the barrel of the invention represents more than three quarters (3/4) of the total height of the barrel. As a result, it is advantageous, in particular due to the bottom raceway ring 36, to have a greater capacity for palletizing the barrels and, at the same time, greater stability and rolling capacity in an inclined position of the barrel. Figure 4 shows the area of the left edge of a barrel with lid 12 of the invention in a cross-sectional representation. At the edge of the lid 16 with a downwardly open "U" shape, a lid seal 30 has been placed or applied by foaming. Between the edge of the lid 16 and the cover plate 80 centrally flat and placed aligned at the same height, a gripping groove 32 is formed with a depth of approximately 25 mm. The grip groove 32 has a flat groove bottom 48, which extends radially towards the inner side by at least 10 mm, preferably in about 15 mm. From the bottom of the groove 48, an annular conical inclined part 52 is lifted on the inner side, in the manner of a connection piece with the flat top cover plate 80. On the underside of the barrel layer 12, two ring flanges 54, 56 which extend approximately 20 mm (axial) are formed below the gripping groove 32 in the outer edge region. The annular flanges 54, 55 are about 20 mm apart from each other and serve to increase the rigidity of the barrel cover 12. On the other hand, the 2-inch hole (about 5 cm) 42 located in the housing of the barrel is observed. opening 50. Of particular importance is the intermediate piece or connecting piece 58, located between the edge of the lid in a "U" shape 16 and the bottom of the slot 48, which is curved or inclined towards the inner side starting from of the edge of the lid 16. This curved connecting piece 58 or the outer axial annular part 54 is supported in the case of the lid of the barrel 12 installed on the outer wall of the barrel body 20 opposite to the retraction or removal 22, increasing by reciprocal support the capacity of stacking the lid or the barrel with lid. In Figure 5 the corresponding partial cut is shown through the upper left edge area ie a barrel with lid 12 of the invention, but laterally outside a hole or a shell of the opening. Here, radial ribs 60 which join the "U" edge of the cover 16 are formed above the curved connection piece. The multiple radial ribs 60 are located at a small lateral distance of about 5 -? up to 10 mm between them.

On the other hand, in this embodiment of the barrel cover 12, a second "V" groove 62 open upwards perimetrally with preferably a grooved groove bottom in the region is disposed radially inwards behind the gripping groove 32. outside of the flat lid plate 80. This slot 62 is interrupted by the casing (s) embedded in the openings and allows to improve the elasticity of the lid against an internal overpressure and the pressure hit produced during the fall of the cap. drum. Figure 6 shows the lower right edge area of a barrel with lid according to the invention with the clamp jaws 64, 66 applied. In lightweight construction, it is necessary that the barrel lid and the opening area of the barrel be adjusted exactly to each other. For this it is necessary that among other aspects to achieve a secure support of the lower jaw of the fork 66, the radial depth of the sacking or retraction 22 measured from the extension line of the fully cylindrical part of the body of the barrel is between 12 mm and 25 mm, preferably around 17 mm. The width of the horizontal support surface for the lower arm of the tension ring 14 or of the bearing surface for the jaw of the drum holder 66 is increased in such a way that the edge of the opening of the solid drum 28 is manufactured during the process of forming by means of blowing with valves or matrix locks by upsetting the thermoplastic material of the barrel wall, forming on the outer and lower side at the edge of barrel 28 a small flange edge 40 with a radial extension about 3 to 5 mm outwards. In Figure 6 it can also be seen that the area of the solid edge of the opening of the barrel 28 facing upward presents a height of about 8 mm upwards as a seal for the seal of the lid 30 a partially circular cross section smooth By means of a special design of the valves of the blow mold it is achieved that this sealing surface of the opening edge of the solid cask 28 incorporated by upsetting, opposite to the seal of the cover 30 and directed upwards, does not present folds and seams of Welding on the stressed plastic material. These folds and weld seams are deviated outwardly and conveniently located on the outer flange edge 40, where they do not interfere to a greater degree. In order to incorporate the gripping area of the clamp of the clamp 64, it is possible to arrange a plurality of radial ribs 60 above the curved connection piece 58 behind the edge of the U-shaped stage.

In order to be able to clarify important features of the invention, in Figure 7 a detailed representation is shown of the upper right zone of the barrel corresponding to a barrel with a lid. The most important construction features consist of the following: A support surface 84 (shown with an arrow) with a width of about 6 mm to 12 mm, preferably 8 mm, slightly inclined, has been formed at the edge of the cover. for the upper arm of the closure by means of the tension ring 14. This prevents the edge of the cover, for example during a fall of the barrel from entering the break-out areas under the tension ring and with this releases the lid seal. By means of the flange edge 40 projecting at the lower outer edge of the opening of the barrel body towards the outer side, a larger supporting surface 18 of at least 10 mm is created for the slightly inclined lower arm of the tension ring 14. . The support surface (in the radial direction preferably has a width of 15 mm (arrow 86).) This is also advantageous for achieving secure attachment of the barrel with the lower jaw of the gripping tool ("parrot's beak"). background of the slot 48 of the external peripheral grip groove 32 is located at the same height as or even somewhat below the lower arm of the tension ring 14. As a result the upper jaw of the fork can grip deep down into the slot grip 32 and secure the barrel with lid securely. The rim of the body of the barrel covered by the tension ring 14 is basically in the form of an inverted "T" with a soul 88 in a horizontal position and a vertical soul 90, located approximately in a central position and directed upwards, where the upwardly directed surface of the vertical web 90 has a semicircular curved shape (radius of curvature of 4.5 mm) and constitutes the seal surface of the body rim of the barrel that it comes into contact with the seal of the cover 30. A partial piece directed outwardly of the horizontal web 88 is represented by the flange edge 40 projecting radially outwards. The partial piece directed towards the inner side of the horizontal core joins the wall of the body of the barrel that moves downwards. In the transition zone of the partial piece directed towards the inner side to the wall of the barrel that continues downwards, the point of intersection or the identified cutting surface has been identified by means of an arrow 92 of the discarded piece cut from the blowing process. The cutting or intersecting surface may follow a vertical path or, as shown, slightly inclined downward and inward. Directly below the cutting surface is a contact zone 92 of the inner wall of the barrel with the outer surface of the barrel lid or the extension of the outer barrel of the lid ring. In the contact area 92, the widest diameter of the barrel body opening is located, which here is smaller by about 2 to 4 mm than in the cutting surface of the discarding piece of the blowing process. By placing the lid the outer core of the cover ring 54 slides into the barrel and in the contact area 92 a radial centering and a support of the cover on the inner wall of the barrel below the cutting surface occurs. of the discard piece of blowing. When some bodies of the barrel have been slightly deformed according to an oval shape, for example due to shrinkage stresses, compensation is produced here by focusing on the area of the opening of the barrel, whereby a laying is achieved uniform and an accurate seating of the seal surface directed upwards of the vertical web element 90 against the seal of the cover 30. Such a centering can not be done with the covers of the conventional casks, which do not extend a part into the barrel, where they come in contact with the inner wall of the barrel. By means of this centering it is possible to adjust the width of the vertical web 90 (8 mm wide, about 9 mm high, with respect to the internal width (around 10 mm) of the edge of the lid with a "U" shape open towards At the bottom, both the outer side and the outside of the vertical core 90 have exact lateral sets 96, 98 (shown by the arrows) of 1 mm in width, thus ensuring that the vertical core element 90 has an impact with the wavy and smooth seal surface always centrally on the seal ring 30. The barrel with lid according to the invention is also characterized in that the larger outer diameter of the barrel cover 12 has the same size as the outer diameter of the rim flange projecting radially outwards (both close butt), where the distance from the front surface of the arm facing downwards from the edge of the U-shaped lid opens downwards to the lateral surface directed to the The top of the flange edge protruding outwards 40 at the edge of the opening of the barrel, the lid being installed and the tension ring closed, is only 1 mm.This ensures that when applying stack overloads, the seal of the lid 30 should only yield 1 mm, after which the outer arm of the edge of the lid comes into contact with the edge of the flange 40 which protrudes outwards and rests on it, thus preventing over-application of the seal 30 .

Another cask with lid according to the invention (European version) without foot ring and with a capacity of 220 liters is shown in Figure 8, which with the lid of cask 12 and with the closure, of the tension ring 14 has a weight of only about 8 kg. The plastic material of the barrel body consists of high molecular weight polyethylene (HD-PE). The upper cover in the form of a disc of the upper lid of the barrel 12, in the present example protrudes with respect to the edge of the lid 16 in the shape of a "U" open downwards or the upper arm of the tension ring 14 that covers it. . The height of the protruding part is approximately two to five times the thickness of the wall or the thickness of the barrel lid, preferably being around 10 mm. This aims to improve the stacking properties in the long term by increasing the defined internal pressure. In a modified embodiment, the lid of the barrel is provided below with a foot ring or a bottom running ring, which is aligned according to a plane with the bottom bottom or is abutting therewith. In Figure 9, the lid of the barrel 12 can be better seen with two holes 42, 44 disposed in respective side hole depressions 50, 50 '. The hole or opening on the left side of 2 inches (5 cm) 42 has been placed for filling and also the extraction of the product with the help of a suction pipe applied. On the other hand, this opening 42 is a hole for residual emptying by means of the inclined design of the upper lid of the lid. The smallest hole, 3/4 inch 19.1 cm) 49 can be opened for venting the barrel during filling or emptying processes. Another very important characteristic is that underneath the gripping groove in the shape of "V" 32, on the inner side of the lid of the barrel 12, the two perimeter annular souls have been formed and moved away from each other 54, 56.? outer ring 54 rests on the inner wall of the barrel. The annular webs 54, 56 are spaced apart by approximately 10 mm to 30 mm, preferably around 20 mm, and extend an axial distance -t about 20 mm into the barrel. The particular feature of this design variant of a barrel with lid resides in the fact that it practically has identical dimensions as the corresponding barrel with a closed "L" ring hole, which is used in the European chemical industry, in such a way that the barrel with novelty lid can be palletized with conventional orifice barrels and can be handled with the same fasteners and conveyors used in conventional drums. The new lidded barrels with their lightweight construction can be manufactured economically and subsequently have no disposal problems, because they are fully recyclable. Here the tension ring 14 can also be a closing ring made of a steel plate, but it can also be entirely of plastic material. In the representation of Figure 10 the lid of the barrel 12 has been cut off beside the 2 inch 42 hole (about 5 cm). On both sides beside the housing of the hole 50 the upper bottom of the lid of the barrel 12 has a configuration inclined downwards towards the edge of the lid. The inclination 68 reaches from the outside to the heel or the beginning of the inner annular core 56 or up to the inner flat edge of the grip groove 32. Thus it is possible that the residual liquid, being slightly inclined the barrel with lid and inverted, it can drain to the lowest point 78 at the upper edge of the inner annular core 56 or the outer edge of the 2-inch hole and exit through said hole to the inside of the barrel. In order to make possible the draining of the residual liquid from the area of the lid or the intermediate space between both elements of annular webs 54 and 56, it has been considered in the present invention that at least one perforation 76 (or a wider transverse opening) is arranged directly in front of the outlet orifice 42 at the inner annular web 56. In a convenient manner, a corresponding perforation has also been arranged in the outer annular web 56, in order to allow the exit of the residual liquid from the slit between the barrel wall and the outer annular web 54. it has formed directly in front of the evacuation orifice 42, seen from the inner side, an annular depression 74, into which the perforation 76 opens into the annular core 56 which leads towards said hole. In the gripping or holding groove 32, this internal evacuation channel is shown as a shoulder-type rib with an upward inclined path towards the discharge hole of the barrel. As seen in Figure 11, the perforations 6 pass through the web elements 54 and 56 in an inclined direction towards the exit hole of the barrel and particularly with a greater inclination toward said barrel exit orifice and particularly with a greater inclination towards said hole than the inclination 68, in such a way that the lowest point 78 results at the outer edge of said hole of the barrel. This can be obtained without problems because the flat bottom of the groove 48 of the gripping groove 32 is located lower than the bottom of the housing of the opening 50. The bottom of the groove 48 is located approximately one or two thicknesses of wall (around 3 mm to 10 mm) of the lid of the barrel below the bottom of the housing of the opening. Figure 12 shows the area of the right edge of a barrel with lid according to the invention according to a cross-sectional view. As can also be seen in the other drawings, the seal of the cover 30 has been installed on the edge of the cover 16 in the form of a "U" open downwards. Between the edge of the cover 16 and the lid disc centrally raised and flat the grip groove 32 is formed, whose depth is between 20 mm to 40 mm. The gripping groove 32 has the flat groove bottom 48, which extends about 15 mm radially towards the inner side. From the bottom of the groove 48 (with the exception of the area corresponding to the opening housing) the inclined conical annular part 52 rises as a connection piece with the upper flat cover plate. On the underside of the lid of the barrel 12 the two annular flanges 54, 56 which are introduced in about 20 mm (axially) into the interior of the barrel body have been formed in the area of the lid. The 3/4 inch (19.1 mm) hole 44 located in the orifice box 50 'is also observed. Basically, the inclination of the lid intended for the residual evacuation of the barrel could also have been formed here. In Figure 13 another embodiment of a barrel with lid according to the invention is exposed (US version). In this case the outlet hole 42 ', according to the usual US design, has an orifice plug 70 that closes said orifice - unlike the usual orifice plug in the European design, which is supported by a ring Closing and sealing in the opening or flange below the thread on a tapered seal seal surface. Another embodiment example shown in Figure 14 differs substantially from the example set forth in Figure 13 because the top bottom or center flat top plate 80 of the barrel cover is aligned with the edge of the lid or is aligned with the upper arm of the tension ring. Due to this in this case the inclination 68 of the flattened area of the lid to the side of the evacuation hole of the barrel correspondingly more flattened. In the case of the lightweight construction of the barrel according to the invention, it is especially necessary that the barrel cover and barrel opening area be exactly adjusted to each other., the special configuration of the upper edge of barrel 28 is of particular importance. For a secure positioning of the lower jaw of the holding tool 66 it is necessary that the radial depth of the take-off 22 - measured from the extension line of the completely cylindrical part of the barrel body - is between 12 mm and 25 mm, preferably of around 17 mm. The width of the inclined support surface for the lower arm of the tension ring 14 or, the bearing surface for the clamp of the clamping fork 66 is increased in such a way that the solid edge of the opening of the barrel 28 is manufactured During the blowing process by means of an upsetting of the thermoplastic deformable material of the barrel wall, with the help of matrix valves, on the outer and lower side at the edge of the barrel 28 the small perimetral flange edge 40 is formed with a radial extension of around 2 mm towards the outer side. The opening edge of barrel 28 has the shape of an inverted "L", which encloses between its long arm (= barrel wall) directed downwards and its short arm, basically horizontal and directed towards the outer side, an angle from about 70 ° to 85 °, preferably around 76 °. The short arm facing outward has a slightly tapered shape on the underside and says it is reducing its thickness outwards. The inclined surface serves as a bearing surface for the lower arm of the tension ring, which due to the inclined bearing surface presses the lid with the seal of the lid, in the closed position, above the upper edge of the barrel. For this, the shorter arm of the "L" is provided on its upper side with a boceled shoulder, which carries a smooth semicircular seal surface above. This embossed shoulder grips on the edge of the "U" lid and seals against the cap seal. The outer edge facing down the edge of the "U" lid closes almost aligned with the edge of the flange 40 oriented radially outwardly from the edge of the opening of the barrel 28, so that also in the case of excessive loading of stacking avoids an excessive solicitation of the seal of the cover. The semicircular region directed upwards from the edge of the opening of the barrel 28 has a height of at least 10 mm and forms the seal surface for the seal of the cover 30. With the help of a special construction of the valves of the matrix of Blowing is achieved that the seal surface facing up the edge of the opening of the upset barrel 28 does not allow folds and weld seams of the upset plastic material. To achieve the advantageous properties of the barrel with lid of the invention, a series of details and refinements adjusted to each other are important, which in their combination constitute the characteristics of this barrel with lid. Described that it has been the nature of the present invention and the way to put it into practice, it is declared that what is claimed as being of invention and exclusive property, is: It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects or products to which the same one refers. The invention having been described as above. Property is claimed as contained in the following:
