20090223963 | Cap For Container Provided With Guarantee Seal - The object of the present invention is a cap provided with a guarantee seal. The guarantee seal consists of guarantee portions comprising an engagement portion and a connecting portion. The seal further comprises bridges for connecting adjacent guarantee portions to one another and a safety portion that makes the engagement portion integral with the handling portion. The safety portion is structurally suitable for keeping the engagement portion constrained in the broken seal configuration, for preventing the forming of dangerous spikes. | 09-10-2009 |
20100038365 | HOT-MELT COMPOSITION FOR METAL CAN AND METAL CAN UTILIZING THE SAME - A hot-melt composition comprising a thermoplastic elastomer, a tackifier, a wax and a polyolefin resin, the wax having a softening point (R & B system) of 140 to 160° C. The hot-melt composition can be easily applied to the mouth-neck portion of a metal can and can be excellently produced. Even when placed under a high-temperature condition, the sealing material that is formed exhibits excellent heat resistance maintaining the sealing. | 02-18-2010 |
20110024424 | Closure Plug - An externally threaded closure plug for tightly closing off the internally threaded opening in shipping and storage containers such as drums, pails and the like. The plug is formed as a cup having a bottom wall and threaded cylindrical sidewall terminating in a circumferentially enlarged rim. Immediately beneath the rim of the plug is a gasket seat defined by the undersurface of the plug rim, the plug sidewall and an annular gasket retaining lip lying in a plane parallel to the undersurface of the plug rim. In use, the plug is screwed into and out of a container wall opening, having an internally threaded portion and an unthreaded portion, the sealing gasket being compressed between the unthreaded opening portion and the plug gasket seat and lying in close proximity to the internal thread. The gasket seat acts to prevent interengagement of the sealing gasket and the opening internally threaded portion. | 02-03-2011 |
20110147384 | CLOSURE ASSEMBLY FOR A CONTAINER - A closure assembly for a container including an internally-threaded annular flange, an externally-threaded closure plug that is received by the annular flange, and an annular gasket positioned between the annular flange and the closure plug for establishing a sealed interface. The container includes a container end panel that is formed over and around a portion of the annular flange and provides an inner axial wall that is positioned between the annular flange and the annular gasket. The clearance between the closing plug and the inner axial wall relative to the size of the annular gasket determines the degree of radial compression of the annular gasket as the plug is threaded into the flange. A radial lip of the plug is designed to contact an upper surface of the container end panel that is formed over the flange as a visual indication when the required tightening torque of the plug within the flange has been reached. | 06-23-2011 |
20120031905 | CONTAINER CAP AND SEAL ASSEMBLIES - A container cap and seal assembly comprises a container base, a cap and a seal engagable with the container base. The seal is held on the cap when the cap is initially installed on the base. When the cap is subsequently opened, the seal disengages from the cap and remains on the base. The seal may then be manually removed and re-installed on the base as desired. The container assembly may be used to contain pastes, liquids and other flowable materials. | 02-09-2012 |
