Problems solved by technology

[0006] In order to solve the technical problem that the elastic tensioning method of the traditional lever-type closure hoop and bolt-type closure hoop cannot reliably clamp the top cover of the barrel, the invention discloses a rigid clamping method. Pressure, so that the hoop of the crimping type closure produces a centripetal plastic curl that rotates clockwise around the crimping of the mouth of the barrel as a whole, and tightly wraps the flange of the top cover of the barrel and the beading of the mouth of the barrel

Embodiment Construction

[0020] Fig. 1 is 200 liters of closed conical steel barrels 7 of detachable barrel top cover. It is equipped with an integral ring-shaped closed hoop-type crimping type closure. The closed conical steel drum is exactly the same as the closed cylindrical steel drum in use, only when the empty drum is transported and the old drum is cleaned and repaired. Just need to insert dismantling port 14 with tool, rotate counterclockwise, open closing device and take off barrel top cover 3. It is transported and cleaned and repaired as a full-open conical steel drum. The functions and structures of its cylindrical barrel body 4, reinforcing ribs 5, conical barrel body 6, barrel body lower part 8, barrel bottom 10 and convex edge 9 are all Known ones are no longer described here.

[0021] From Fig. 2 and Fig. 3, it can be seen that the flange 12 of the bucket top cover 3 is composed of two overlapping arc grooves with different radii. Under the clamping effect of the side 23 and the wrap...

Abstract

The invention discloses a closed entry cone steel barrel sealing crimping edge sealer that could uninstall the cover, and the sealing clamping and manufacturing method. The invention uses O shaped sealing and self-sealing principle to form fixed sealing slot space between overlapping circle arc slot and crimping edge. When the sealer clamps, O shaped ring would uses resilience to sealing the cover and bung. When conveying for a long distance, the cover could be uninstalled to save 70% conveying cost. When the old steel barrel needs to clean and repair, the cover could be uninstalled and the cleaning device could insert into barrel. Thus, the cleaning cost could save 50%.

Description

Technical field: [0001] The invention relates to a steel packaging container used in the field of packaging, and a closed conical steel drum closing hoop-type crimping type closure with a detachable top cover of the drum. The closure enables the top cover of the closed conical steel drum to be removed from the body of the drum, thereby converting the closed conical steel drum into a fully open conical steel drum. The invention also relates to a sealing method and a clamping method of the closure, as well as a manufacturing method of multiple crimping of the bung mouth and a crimping type closure hoop. Background technique [0002] 200 liters (216.5 liters in British) closed cylindrical steel drum is the most widely used steel packaging container in the world. It has a TM60 (G2 in British) injection port and a TM27 (G3 / 4 in British) vent on the top cover of the barrel. The international steel drum standard ISO 15750-2:2002 calls this kind of steel drum a drum with a non-remo...
