The invention is a single portable water bottle unit that delivers a convenient method of providing hydration to two separate parties. It consists of four main components; a lid, housing, a connector, and bowl. The components are connected to each other via threads and can be assembled and disassembled at anytime. The connector is responsible for controlling liquid flow via mechanical apparatus initiated through the compression of a button-trigger located on its side. When the button-trigger is compressed, liquid vacates through the bottom of the housing, through the connector, through a removable filter attached on the bottom of the connector, and finally into the bowl. The bowl enables a second party to consume the contents dispersed from the housing without having to consume from the same orifices as the first part, which fastens and unfastens to the bottom of the connector.

A stopper for use with a container containing liquids, solids, or gases. The stopper includes a main body. The main body includes an upper portion. The upper portion has a diameter greater than a diameter of an opening of the container. The stopper also includes a flexible sheath affixed to the stopper. The sheath can be rolled down an exterior surface of the container to facilitate a seal of the container. In addition, the main body includes an annular groove sized and shaped to retain the sheath when rolled up. In one embodiment the present invention may include a lower portion having a plug sized and shaped to fit within the opening of the container to prevent liquids, solids, or gases contained in the container from exiting the opening.

The present disclosure relates to the field of bottle stopper devices, and in particular, to a quick opening and closing container stopper, which includes a fixed shell and a movable stopper body. The fixed shell is provided with a dodging opening. The movable stopper body is provided with a limiting plate. An elastic sealing sleeve abuts against and between the limiting plate and the fixed shell. A knob is rotatably connected to the movable stopper body. The knob includes a side lug. When the container stopper is in a locked state, the side lug extends beyond a contour range of the dodging opening, and the fixed shell and the limiting plate are close to each other and drive the elastic sealing sleeve to bulge outward. When the container stopper is in an unlocked state, the side lug is accommodated in the dodging opening.

The present invention relates to a container tamper detection capsule (1) comprising an upper cover member (2), a lower cover member (4) and an axial displacement member (3), wherein the latter comprises an alignment member (5) and an insertion member (6). Said axial displacement member (3) is axially displaceable from a first closed position, to a second open, fixed and irreversible position. The invention also relates to a container lid (8) comprising the capsule (1) and a stopper member (7). Lastly, the invention also relates to production processes for the capsule (1) and lid (8), which are intended to close containers of food or non-food products.
