Definitions

• the barrel is composed of a body, generally cylindrical, often grooved, a bottom, often domed, and a top, generally dish.
• the barrel is in principle hermetically closed, the openings being generally located on the flat upper part, in the form, for example, of two screw bungs with threaded plug.
• the so-called "flat upper” part is in fact hollowed out with respect to the cylindrical wall of the barrel and thus constitutes a sort of bowl, or depression, more or less deep depending on the types of barrels.
• this bowl, or depression constitutes a sort of reservoir for the rainwater which settles there and stagnates there, without any device making it possible to prevent it, or to infiltrate little by little, thus penetrating into the metal barrel, with the obvious risk of altering the quality products, for example lubricants, stored there. It follows, in the example chosen, for the lubricant manufacturer who stores and delivers his products in metal drums, a risk technique of having to deal with complaints from its customers, depending on whether this alteration by infiltration has been effective or whether the only risk exists that it could have occurred at any time before the drums containing the lubricants have been delivered to customers.
• the aim of the present invention is to remedy the above-mentioned drawbacks and to provide enhanced and complete protection of the products stored in barrels. It relates in particular to a device capable of hermetically covering the upper part of the barrel with a clip-on cap preferably made of plastic, so that this cap does not require during its installation or its removal any additional device such as metal strapping or other, and that, even in the event of exposure to the weather, water cannot penetrate between the cap and the metal part of the barrel, let alone remain there.
• the present invention therefore essentially relates to a cap made of synthetic resin, the diameter of which corresponds to the diameter of the barrel to be covered and protected, the periphery of this cap having, when molded, a special profile with a constricted part forcing a deformation for placing by force of the cap on the rim of the barrel, the relaxation after implementation simultaneously ensuring the energetic retention of the cap on its support and sealing against external agents, thus making it possible to isolate the upper bowl from the barrel around the circumference of which the cap is placed.
• thermoforming a sheet of low density high density polyethylene pressure hereinafter referred to as PeHdBp, may constitute an embodiment of this cap.
• PeHdBp a sheet of low density high density polyethylene pressure
• Fig. 1 is a partial perspective view, from above, of a metal type barrel, for example, intended for the storage and transport of lubricants.
• Fig. 2 shows the cap being put in place by peripheral clipping.
• Fig. 5 is a view similar to FIG. 4, but in this case the cap has notches or ribs stiffening and stiffening facilitating nesting - dislocation as well as tightening on top of the barrel to be protected.
• the barrel is shown in 1, the top to cover and protect, in l "a, the cap in 2, its peripheral profile seen in section is shown in 3a, 3b, and a stiffening notch is shown in fig. 5 in 4.
• the examination of the figures makes it perfectly understand the structure of the cap and its process of positioning by clipping.
• ribs may be more or less numerous, arranged on a part or on the entire periphery of the cap. These are the ribs which, combined with the undercut and the precise calculation of the primary and secondary shrinkage of the plastic material, will ensure automatic clipping of the cap on the upper part of the barrel, without any additional device being necessary. , neither for fitting nor for tightening, nor for removing this cap, which has obvious advantages in terms of handling costs.
• thermoforming of other types of plastics either in natural color or in different colors, or even the injection molding of said caps undercut, without these examples are exclusive or limiting.
• thermoforming of other types of plastics either in natural color or in different colors, or even the injection molding of said caps undercut, without these examples are exclusive or limiting.
• notches, or ribs which ensures great flexibility of use when fitting or removing the cap, and allows effective clamping on the metal barrel, at the same time as a possibility of adaptation to variations or tolerances in diameter for a type of metal drum considered.
• this cap is not the closing of the metal barrel, already operated in hollow by the metal part previously called flat upper part, but its protection against bad weather, and in particular against the deposition and infiltration of water from rain.
• a plastic with high shrinkage such as high density, low pressure polyethylene, makes it possible, by working over a well-defined temperature range, taking into account the direction of extrusion of the sheets or plates used, to obtain optimum shrinkage at the undercut and ensures satisfactory tightening of the cap on the barrel.
• plastic material which can be either translucent, and in this case allow correct reading of the references appearing on the upper part of the metal barrel, or opaque, of different colors which may possibly allow rapid identification, depending on the color of the cap, products stored in metal drums.
