Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] refer to image 3 As shown, the present invention discloses a multifunctional bung, which is used to be screwed on the flange 10 at the top 30 of the bucket, and the flange 10 at the top 30 of the bucket has internal threads; the multifunctional bung includes U-shaped plug body 20, U-shaped plug body 20 has an external thread that can match the internal thread of the flange 10, and the U-shaped plug body 20 is screwed on the flange 10 through the cooperation of the external thread and the internal thread; the U-shaped plug body The top of 20 has an outer flange 201, and the inner corner of the outer flange 201 is provided with an annular gasket 202. When the U-shaped plug body 20 is screwed into the flange 10, the annular gasket 202 is in contact with the inner wall of the flange 10. The joint acts as a closed steel drum; the outer flange 201 ex...

Abstract

The invention discloses a multi-functional drum plug and a special wrench for the same and relates to the technical field of container drum plugs. The multi-functional drum plug comprises a U-shaped plug body, the U-shaped plug body is provided with an external thread. Outer flanges are arranged at the top end of the U-shaped plug body and extend outwards to form reversed stretched bodies. The reversed stretched bodies retrace inwards. At the upper portion of the container drum plug, the outer flanges or the reversed stretched bodies are circularly cut with a breaking state and are inset in situ to form implicit fault zones. Blocking teeth are arranged in a cross type at the tail ends of the reversed stretched bodies. The multi-functional drum plug has the advantages that after a hasp of the multi-functional drum is canceled, the U-shaped plug body is only closed and opened by the special wrench so as to achieve an unmatched anti-fake function, omit steps of welding the hasp during manufacturing the container drum plug and simplify manufacturing processes of the drum plug; besides, waterproof, dustproof and anti-fake objectives are achieved without a sealing cap.

Description

【Technical field】 [0001] The invention relates to a container bung cover, more specifically, the invention relates to a multifunctional bung for steel drums and a special wrench for the multifunctional bung. 【Background technique】 [0002] At present, the bungs of steel drum closures used in my country are produced according to the standard of GB / T13251-2008 "Packaging, Steel Drums, and Embedded Flange Closures". Type flange closure "Standard page 4 barrel plug structure. refer to figure 1 As shown, the barrel plug is composed of a U-shaped plug body 1 and an additional welded trip button 2 for closing and unwinding. This U-shaped plug body 1 can only play the role of sealing the steel drum, and cannot prevent dust and counterfeit. To remedy this shortcoming, refer to figure 2 As shown, after the bung is closed, the international embedded flange sealer is equipped with a sealing cover 3 on the outside. While the sealing cover 3 is dust-proof, the pre-filled sealing packin...
