A hollow needle insertion structure used in a wine fresh-keeping device may be shown and described. A wine bottle installation chamber, where the wine bottle installation chamber is arranged in a containing chamber, and one end of the wine bottle installation chamber is matched with an exchange port, a wine sleeve, the wine sleeve is arranged in the wine bottle installation chamber, and a cooperating movement threads is provided between outer side wall of the wine sleeve and inner side wall of the wine bottle installation chamber; and a hollow needle, the hollow needle is matched with the wine bottle installation chamber; after the wine bottle is installed in the wine sleeve, the wine sleeve moves along the cooperating movement threads into the wine bottle installation chamber, and after contact with the hollow needle, the hollow needle is inserted into the wine bottle under the rotation of the wine sleeve.

Provided is a tip set used for a genetic testing device. The tip set includes a piercing tip breaking a lid portion of a reagent container filled with a reagent to open the reagent container and an injection tip injecting a sample solution containing a target gene nucleic acid into a microchip. The injection tip has a reservoir storing the sample solution in an internal space and an injection needle protruding from the reservoir, an opening the internal space to a side opposite to the injection needle is formed in the reservoir, and the piercing tip has a fitting portion fitted to the injection tip to connect the injection tip and the piercing tip.

The disclosure relates to a container opener for opening a planar portion of a sealed container by cutting the planar portion of the container, while leaving little to no sharp edges on the container at the point of the cut.

A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

An apparatus for making a combination liquid includes a housing, a first container, an opening mechanism for opening the container, a chamber with an outlet, a liquid reservoir, and a pump.

The disclosure relates to a container opener for opening a planar portion of a sealed container by cutting the planar portion of the container, while leaving little to no sharp edges on the container at the point of the cut.

A pressure equalising device (10) which has a squat shape and which has three positions which are a first unlocked and retracted position, a second locked and retracted position, and a third unlocked and extended position wherein the device comprises a spike (14) for piercing a container, a biasing member (12) to bias the device into the first position from the third position, an upper body (20) which supports the spike and which has a locking formation (28), and a lower body (40); wherein the device has a twist lock such that the device can be rotated to and from its first and second positions; wherein the twist lock comprises a slot (52) in the lower body which is positioned to receive the locking formation (28) to immobilise the upper body (20) in relation to the lower body (40); the invention provides an ergonomically acceptable and safe way to reduce the torque force required to open the typical jar to less that 2 Nm by equalising the pressures inside and outside the jar.

We describe apparatuses, systems, method, reagents, and kits for conducting assays as well as process for their preparation. They are particularly well suited for conducting automated sampling, sample preparation, and analysis in a multi-well plate assay format. For example, they may be used for automated analysis of particulates in air and/or liquid samples derived therefrom in environmental monitoring.

A jetted bag opener separates mixed solid waste from flexible containers such as plastic and paper bags, and includes a housing configured with an ingress and an egress, at least two sets of a plurality of fluid delivery nozzles, where a first set of the nozzles is arranged along a sidewall at a first side of the housing, and a second set of the nozzles is arranged along the sidewall at a second side of the housing opposite the first side, and as fluid is sprayed from the nozzle outlets, the fluid is delivered at a force sufficient to penetrate into the flexible containers passing through the housing to thereby create an opening in the flexible containers for release of the mixed solid waste held therein.

An apparatus for making a mixed drink includes a housing, a first container, a second container, a first opening mechanism for opening the first container, a second opening mechanism for opening the second container, a chamber with an outlet, a water reservoir, and a pump. The first container holds a concentrate and the second container holds an alcohol.
