A wine funnel for facilitating the transfer of wine from a bottle to a decanter includes a frustoconical housing having a top wall, a substantially continuous outer wall, and a lower end. Centrally positioned on the top wall is an elevated ball for dispersing wine into smaller, multidirectional streams. The top wall also includes a plurality of concentric grooves that trap sediment from wine deflected by the ball. The grooves are in fluid communication with an internal spiraled passageway having a plurality of venturi ports for efficiently importing ambient air into wine as it flows through the housing and into a decanter or wine glass.

An anti-spill funnel assembly which includes an outer reservoir funnel having a center funnel positioned therein. The outer reservoir funnel includes a cone-shaped portion having a spout extending downwardly therefrom. The center funnel includes a cone-shaped portion having a hollow stem extending downwardly therefrom. This center funnel also includes a spout extending downwardly from the lower end of the cone-shaped portion thereof. The hollow stem portion has a plurality of vertically disposed slots formed therein. When the funnel assembly is being used to fill a container or a piece of equipment, the spouts of the reservoir funnel and center funnel are inserted downwardly into the fill opening of a container or equipment. As liquid is poured into the container or equipment, any overflow liquid is passed upwardly into the outer reservoir funnel to prevent a spill.

Disclosed is a mating structure of a liquid extraction piece and a test tube assembly, which comprises the liquid extraction piece (1) and the test tube assembly (4). A test tube plug (2) is arranged at an opening end (32) of a test tube (3). The lower portion of the liquid extraction piece (1) is mated with the test tube assembly (4). The body of the test tube plug (2) is provided with a blocking body (25). The blocking body (25) is provided with a movable portion (253) and a fixed portion (252). The movable portion (253) can move with respect to the fixed portion (252). An axial recess is arranged above an upper surface (251) of the movable portion (253). The lower portion of the liquid extraction piece (1) is mated with the recess. The blocking body (25) is located in a lumen (31) of the test tube (3).

A vented funnel assembly for venting a receptacle while liquid is poured into the receptacle includes a first funnel that is insertable into a neck of a receptacle. A second funnel is nested in the first funnel and a liquid can be poured into the second funnel when the first funnel is inserted into the neck of the receptacle. The second funnel is separated from the first funnel to define an air passage between the first funnel and the second funnel. In this way the air passage can ventilate air within the receptacle when the liquid is poured into the second funnel.

The bottle transfer coupling device is adapted for use with a plurality of containers. The bottle transfer coupling device is a device that transfers the contents of a first container selected from the plurality of containers to a second container selected from the plurality of containers. The bottle transfer coupling device transports the contents of the first selected container to the second selected container using a sealed transport mechanism that minimizes the loss of the contents of the first container or the second container during the transfer process. The bottle transfer coupling device comprises a first funnel, a second funnel, and a coupling pipe. The coupling pipe attaches the first funnel to the second funnel to create a fluid bearing channel between the first funnel and the second funnel such that fluids from the first container will be transported to the second container.

A fuel reservoir apparatus for facilitating filling an electric generator with fuel and retaining auxiliary fuel includes a container comprising a perimeter wall which bounds a chamber for retaining the auxiliary fuel. The container has an outlet to the chamber which is positioned at a bottom end thereof and an inlet to the chamber which is positioned at a top end thereof. A connector is coupled to the container and is configured to fluidly couple the chamber to a tank of an electric generator through the outlet.

A vented funnel assembly for venting a receptacle while liquid is poured into the receptacle includes a first funnel that is insertable into a neck of a receptacle. A second funnel is nested in the first funnel and a liquid can be poured into the second funnel when the first funnel is inserted into the neck of the receptacle. The second funnel is separated from the first funnel to define an air passage between the first funnel and the second funnel. In this way the air passage can ventilate air within the receptacle when the liquid is poured into the second funnel.

A liquid filling device is provided, including: a base, a connecting assembly, a pressure gauge, at least one filling assembly and a negative pressure generator. The base includes a channel, and the channel extends through the base and includes at least one liquid inlet, a first gas port, a second gas port, an assembling opening and a measuring port. The negative pressure generator includes a tube body and a venturi structure, and the tube body is disposed through the base and includes a penetrating portion disposed through the channel. The penetrating portion has at least one through hole, and the venturi structure is received within the penetrating portion and communicated with the channel. When a gas is passed through the venturi structure, a negative pressure is generated to extract a gas in the container to be filled.

A multipurpose vented funnel is a device for funneling liquid, wherein the device includes a conical hollow body, having a wide top opening, directed into a smaller outlet spout. The inner wall of the conical hollow body includes a linear pattern of grooves, extending horizontally from the top of the inner wall to the bottom. The outer wall of the conical hollow body has a handle, which is part of a rectangular passageway for the venting of air or gas, from a reservoir and/or container. In addition, a plurality of stabilizer tabs, outwardly project from the outlet spout for the stable supporting of the funnel inside or reservoirs and/or containers.
