Insert for a pressurized container of liquid
First Claim
1. An insert adapted for addition to a gas-pressurized liquid in a liquid container, the liquid container also having a headspace adjacent to the gas-pressurized liquid, comprising:
- a body that is activated by pressure, having a perimeter and at least one first cavity, said body having an opening that allows said at least one first cavity to communicate with said headspace; and
a positioning device interconnected to at least a portion of said perimeter of said body and arranged outside said perimeter of said body, said positioning device having at least one second cavity, said positioning device further comprising;
an opening arranged in a lower surface of said positioning device, which is in communication with said at least one second cavity, said opening being submerged in the gas-pressurized liquid when said insert is floating on the gas-pressurized liquid,a ventilation opening arranged in an upper surface of said positioning device, which is in communication with said at least one second cavity, that directly communicates with the headspace,said lower surface of said positioning device being coplanar with a lower surface of said body,wherein said at least one second cavity ensures that said insert will sink into the gas-pressurized liquid when said at least one second cavity is filled with the gas-pressurized liquid, andwherein said at least one first cavity is maintained in an upright position for communicating with a headspace in an un-submerged state and for releasing contents when said insert is submerged in the gas-pressurized liquid.

Abstract
The invention relates to an insert that is to be added to a gas-pressurized liquid in a container. Said insert comprises a pressure-activated body with at least one cavity, said body being connected to a positioning device. According to the invention, (a) the pressure-activated body (4) comprises at least one opening (10) with a reduced diameter, which connects the cavity to the environment of the insert and is situated in a location that lies above the level of liquid when the insert is floating on said liquid and (b) the positioning device comprises a floating body (1, 2; 1, 2, 6) with a small opening (3), which is submerged in the liquid when the insert is placed on the latter, a ventilation opening (5), which communicates directly with the external environment (14) of the insert and a minimum volume (11), which when filled with liquid enables the insert to sink into the liquid. The inventive insert can be added to liquids that are sealed under pressure. It floats to the surface of said liquid, but sinks after a period of time. Its pressure-activated body is charged with the internal pressure of the sealed container and when the container of liquid is opened, said pressure is used in a known manner to achieve effects such as an improved foaming of beer or to mix a substance, which up to the point of opening has been stored separately in the container, with the liquid.
