The present disclosure provides a chemical container and a method for manufacturing the same. The chemical container comprises a head portion having a top wall and a head sidewall extending from an edge of the top wall, as well as a body portion jointed with the head portion and defining a chamber together with the head portion. The top wall has a mouth structure configured for one or more pipelines to pass through and connect with the chamber. The manufacturing method is simple and of low cost, and the resulted chemical container is able to withstand a greater internal pressure and is configured to collect any leaking liquid chemicals.

The present invention relates to a keg chime configured to be mounted to a keg, for example a blow moulded plastic keg. The chime may include a handle that has a waveform profile when viewed in cross-section along a length of the handle. The handle may include a first set of one or more regions of inflection that provide a first surface of the handle and a second set of one or more regions of inflection that provide an opposing second surface of the handle. The chime may be configured to be connected to a sleeve for surrounding at least part of a body portion of the keg. The interface between the chime and the sleeve may be configured to permit axially outward movement of the chime with respect to the sleeve in order to accommodate axial expansion of the keg.

The present invention relates to a top chime for a beverage keg. The top chime is configured to be readily removable from the keg, for example to enable recycling of the top chime separately to the keg. The top chime comprises a mounting portion for mounting the top chime to a keg in use, and a mounting element separate to the top chime that is configured to be assembled together with the top chime after the top chime has been moved into a mounted position with respect to the keg to thereby secure the top chime with respect to the keg. The top chime is provided with a mounting element that is configured to engage the mounting portion to thereby secure the top chime with respect to the keg. The mounting element is configured to be assembled together with the top chime by moving the mounting element in a radially inward direction with respect to a longitudinal axis of the top chime.

A self-drilling, self-tapping bone screw is described in which the bone screw has a drill tip free of threads and having a length at least as great as about the thickness of a proximal cortical bone layer, with the drill tip having opposed lands and a helical flute between each of the lands with each of the lands having a cutting edge configured to cut bone as the drill tip is rotated into the bone with the flutes conveying the bone debris away from the drill tip, where a lead thread begins to self-tap internal threads in the proximal cortical bone layer after the drill tip has drilled through the proximal cortical bone layer so as to avoid stripping the threads formed in the bone layer. A method of installation is also disclosed.

A container for sterilising objects, includes: a hollow body with mainly longitudinal development and closed at one end by a bottom, the hollow body being provided at the opposite end with an opening in proximity to which there is a first connection area; a substantially tubular body provided, in proximity to its ends, respectively with a second and a third connection area, each one of which is suited to be alternatively coupled with the first connection area of the hollow body. The container furthermore includes a shaped cover provided, at the level of its inner side walls, with a fourth connection area suited to be coupled with one of the connection areas of the tubular body and with the hollow body; a support is arranged inside the tubular body and in proximity to one of its ends, the support being configured so as to support one or more objects to be sterilised; a maximum pressure valve applied to the hollow body.

A set of preforms to make a container for beverages, comprising an external preform and an internal preform, each intended to form respectively an external keg and an internal bag of the container. The internal preform is associated internally with the external preform in order to define with the external preform a hollow space. The external preform and the internal preform have respective coupling members suitable to clamp the external preform and the internal preform with respect to each other in a desired reciprocal position.

The present invention relates to a bottom chime for a beverage keg. The bottom chime is configured to be push fitted onto the keg, and to subsequently be removable from the keg, for example to enable recycling of the bottom chime separately to the keg. The bottom chime comprises a plurality of inwardly extending engagement elements that are configured to form a snap fit engagement with a corresponding plurality of recesses provided in the body of the keg.

A palletised container assembly includes a pallet providing a base, and a group of containers (1) are arranged and supported on the pallet with a wrapping band stretched around the containers to hold them together. Each of the containers has a container (body 2), two chimes (3), (4) secured to the top and bottom ends of the container body, and a valve assembly (8) which incorporates a draw tube (8a) extending within the container body. Each chime has a substantially circular peripheral outer wall (9), (10) which, at its widest point, is provided with a series of circumferentially-spaced projections (15) which engage the projections of adjacent containers to restrict relative movement between the containers in transit.

A self-drilling, self-tapping bone screw is described in which the bone screw has a drill tip free of threads and having a length at least as great as about the thickness of a proximal cortical bone layer, with the drill tip having opposed lands and a helical flute between each of the lands with each of the lands having a cutting edge configured to cut bone as the drill tip is rotated into the bone with the flutes conveying the bone debris away from the drill tip, where a lead thread begins to self-tap internal threads in the proximal cortical bone layer after the drill tip has drilled through the proximal cortical bone layer so as to avoid stripping the threads formed in the bone layer. A method of installation is also disclosed.

A double-layer keg comprises an outer barrel and an inner barrel made of plastic disposed in the outer barrel. A bottom of the outer barrel is fixed with a base, and a lower portion of the outer barrel has a brace for supporting a bottom periphery of the inner barrel. A spear structure is installed at a barrel opening of the inner barrel, and an upper portion of the inner barrel has a shoulder and a neck disposed around the barrel opening. An inner surface of an upper portion of the outer barrel is pressed against an outer surface of the shoulder and/or the neck of the inner barrel. An expansion space, provided for the bottom of the inner barrel to expand downward, is disposed between a portion of the bottom of the inner barrel located at an inner side of the brace and the base.
