A sealing cap made of an elastic plastic material for a container closure includes a container socket base formed on a container for disposing a container socket having a bung plug disposed in a bung socket formed on the container socket base, the sealing cap comprising a lid disk which has a fastening means disposed on an underside of the lid disk and provided with a snap-lock means for forming a snap-lock connection with the bung plug, and an edge skirt disposed at the circumference of the lid disk and connected to the lid disk via a predetermined breaking means. The lid disk has a support means for supporting the lid disk on the container socket base, the support means being disposed radially inside adjacent to the predetermined breaking means on the underside of the lid disk.

Sealing cap for a container closure and container closure comprising such a sealing cap

A bung plug seal for bung containers, the bung plug seal having a bung plug for being disposed in a bung socket of the bung container, the bung plug having a plug depression for inserting a fitting tool, the plug depression having a depression bottom provided with at least one ventilation opening, and the bung plug being provided with a ventilation plug which is disposed in the plug depression and a thread bolt of which is accommodated in an internal thread of a receiving hole formed in the depression bottom and which has a lid disk provided with a handling unit and connected to the thread bolt for sealing the ventilation opening in a closed position of the ventilation plug.

Bung plug seal

A bung plug closure for bung-hole containers includes a bung plug for being placed in a bung neck and a seal cap for closing a plug recess formed in the bung plug, the plug recess having a space for receiving a dimensionally elastic engaging body formed on the seal cap and having a radial locking protrusion, a valve disposed in a bottom of the plug recess, the valve having a valve body disposed in a valve opening of a bottom recess, the valve body including a valve cover connected to the bung plug, the valve cover being an elastically deformable disk, the valve cover connected to the bung plug such that a circumferential edge of the valve cover, which protrudes radially outward over matching locking elements for interlocking with the locking protrusion, is received between the locking protrusion of the engaging body and a recess edge of the bottom recess.

Bung plug closure for bung-hole containers

A transport and storage container () for liquids comprising a pallet-type understructure () for a plastic inner container () and a cage () having horizontal bars () and vertical bars () made of metal for housing the inner container, lower ends () of the vertical bars having a connecting portion (), which is formed by deformation and has a trough-shaped recess (), for being welded to a lower edge profile of the cage (), wherein, to define a bending portion (), the vertical bars () have another trough-shaped recess (), which is disposed adjacent to the connecting portion () and which has a recess opening () formed on the inside () of the vertical bars (), which faces the inner container (), and a trough bottom () formed by a flattened portion of the hollow profile ().

Transport and storage container for liquids

A bung plug closure () for fastening a plug depression formed in a bung plug (), said plug depression comprising a receiving area for receiving a resilient engagement body realized on the seal cap (), and said bung plug () comprising tool engagement projections (), which are arranged on an inner wall of the plug depression and which are distanced to each other via gaps () and which delimit the receiving space using inner surfaces (), counter-locking elements () being provided in the plug depression, said counter-locking elements () being arranged in the area of the gaps () above an annular frame (), which is formed outside of the gaps () via lower sections () of the inner surfaces ().

Bung plug closure

A seal cap () for a container closure includes a cover disc () having a fastening ring, connected to an underside of the cover disc, with a latching element, for producing a detachable engagement connection with the container closure, connected to a pull tab arranged at the circumference of the cover disc via a connecting element. The connecting element has a cover strip formed in the cover disc that is separated from adjacent areas of the cover disc by lateral cover-strip predetermined breaking lines, which have predetermined breaking elements and has a pull web connected to the latching element of the fastening ring. The cover strip extends from the pull tab, at the circumference of the cover disc into a central inner portion () of the cover disc within the fastening ring and the pull web is arranged in an intersecting area between the cover strip and the fastening ring.
