A container system is provided comprising an upper container and a clip body configured to attach to the top of a lower container. The clip body includes outer securing structures comprised of tabs and ledges to releasably attach to the lip of a circular rim of the lower container. Wings are configured to flex under an influence of a digit of a user to bias the ledges away from the central region of the clip body, thereby releasing the lower container.

The disclosed fluid transfer device is a multipurpose, efficient way to transfer viscous fluid from one container to another. The fluid transfer device comprises a body component that is configured in a cylindrical shape with opposing ends sized large enough to accept the threaded connection from various fluid-holding containers. The body component would be of various lengths and diameters to allow for the mating to different bottles like those containing ketchup, ranch dressing, shampoo, ointments, creams, lotions, and numerous other viscous fluids. The body component also comprises a center section with threaded features to allow the user to thread the fluid transfer device onto fluid containers. Thus, each fluid transfer device functions as a suitable way of allowing the complete and clean transfer of viscous fluids from one container to another container.

A device that has a device body defining an opening at one end thereof, a storage chamber within the device body for storing multiple doses of a substance therein, and a sliding stopper, sealing engageable with the device body, through which the chamber is filled. The stopper has a body and a flexible portion, which may be in the form of a plurality of flexible members, extending therefrom. The flexible portion or members are movable between first and second positions. In the first position, during filling, the portion or members are substantially laterally extending from the stopper body and engaging the opening of the device body. Accordingly, the axial position of the stopper with respect to the device body is secured during filling of the chamber therethrough. In the second position, after filling, the portion or members are substantially axially-extending from the stopper body and disengaged from the rim or opening of the device body. Accordingly, the stopper is axially slideable through the body.

A container carrier for unitizing a plurality of containers that includes a first engagement means configured to engage a can and a second engagement means configured to engage a bottle, wherein the first engagement means and the second engagement means are generally superimposed upon each other.

A container assembly to facilitate liquid transfer from a donor container to a recipient container that includes recipient container with a main body, a bottom sidewall member couplable to the main body, that has a lower surface to enable the recipient container to be placed in an erect orientation, and has a bottom aperture for receiving a selectively removable disc. The bottom sidewall member may include a flange member projecting from an inner surface thereon and that is configured to stop linear movement of a piston placed inside of the main body and moved with a stem that is insertable through the bottom aperture and attachable to the piston, wherein the user moves the piston with the stem to generate a negative pressure to induce liquid in a donor container to be transported to the recipient container.
