A stretchable bottle container for usage as an umbrella accessory, or a packaging and storage container. The stretchable bottle container comprises: a stretchable bottle body (1), a bottle cap (2), and hanging accessories (3) for portability purposes. The opening of the stretchable bottle body (1) is connected with the bottle cap (2) through a detachable tightening seal connection which is airtight and waterproof. The body (1) of the stretchable bottle is a cylinder which has one closed end and one open end, wherein the wall of the cylinder contains stretchable wavy structures. The size difference between the diameters of the opening of the bottle and that of the body (1) is less than 10%. The opening of the bottle body is soft and deformable under the pressure of finger squeezes.

Hanging accessories (3) for portable purposes are connectable with the bottle cap (2) through a sectional structure which is capable of undertaking repeated detachments and re-attachments or a hanging carabiner which has open and shut configurations. The present utility invention provides a stretchable bottle container with technical advantages of having a soft and wide mouth opening which is deformable under finger squeezes, compactness in stock volume, high portability, good compatibility for different sizes and a waterproof and airtight insulation.

A container including a storage chamber within which is located at least one concentrated product housed; a mixing chamber coupled to the storage chamber; and a closure element, wherein the storage chamber is isolated from the mixing chamber; the mixing chamber is defined by a body having a longitudinal length defined between opposed ends and along at least a portion of the length of the mixing chamber, the body defines circular bellows, such that the mixing chamber has a collapsed configuration when the ends of the body are urged together and an expanded configuration when the ends of the body are urged apart, the bellows further including a latching arrangement which acts to latch the bellows in their collapsed configuration and/or their expanded configuration; and wherein a first end of the mixing chamber is open and is selectively closable via the closure element.

A catheter connector assembly which may be included with a corporeal drainage system, and a method of draining fluid from a bodily cavity. The catheter connector assembly may include a catheter connector and a drainage line connector. The catheter connector may include a connector body with a coupling feature, a deformable sealing element, and a retaining member. The drainage line connector may include a drainage line body first and second hinge clips, and an actuator. The actuator is designed to deform the deformable sealing element when the drainage line connector is coupled to the catheter connector.

The size difference between diameters of the opening of the bottle and that of the body (1) is less than 10%. The open end of the bottle body is soft and deformable under inward pressure of finger squeezes. Hanging accessories for portability are connectable with the bottle cap through a sectional structure with capability of repeated detachments and re-attachments or through a hanging carabiner which has open and shut configurations. The present utility invention provides a stretchable bottle container with technical advantages of having a wide mouth opening with waterproof and airtight insulation while being soft and deformable under finger squeezes, compactness with compressible volume, easiness in portability and compatibility for different sizes.

A semi-rigid collapsible container has a side-wall with an upper portion, a central portion, a lower portion and a base. The central portion includes a vacuum panel portion having a control portion and an initiator portion. The control portion is inclined more steeply in a vertical direction, i.e. has a more acute angle relative to the longitudinal axis of the container, than the initiator portion. On low vacuum force being present within the container panel following the cooling of a hot liquid in the container the initiator portion will flex inwardly to cause the control portion to invert and flex further inwardly into the container and the central portion to collapse. Raised ribs provide an additional support for the container in its collapsed state. In another embodiment the telescoping of the container back to its original position occurs when the vacuum force is released following removal of the container cap.
