A container lid includes a lid for sealing a filling tube connected to an external environment. A bottom end of the lid is provided with a hollow inner cavity, and an inner side wall of the hollow inner cavity is provided with a thread. An upper end of the lid is provided with at least two sliding grooves. The present invention can be used for sealing container filling tubes. Moreover, the lids of the present invention can be assembled to form any combined shapes, thereby reducing garbage pollution and promoting environmental protection.

A paper bottle includes a cap, a mouth, a body and a bottom. The mouth has a tube and a body top. The cap can be to seal the tube. The tube is made of biodegradable plastic. A top end of the body is closely connected with the body top. The body is consisted of two layers of paper-based composite paper. The two layers of paper-based composite paper are spirally wound to form a tubular structure. The bottom is made of wood-pulp paper and closely connected with a bottom end of the body.

A protective bottle enclosure includes a base portion defined by a base sidewall secured to a base bottom wall and having an open top. The base bottom wall has a base pad attached thereto. An upper portion is defined by an upper sidewall surrounding an internal cavity. The upper portion has a cylindrical body section with a generally constant body diameter between a lower section and a neck section. The lower section is narrower than the body section and ends in a lower opening. The neck section is narrower than the body section and ends in a neck opening. The neck section includes a tapered portion and a straight portion. The lower section can be inserted into the open top of the base portion and threadably and removably engage the base sidewall. A removable cap includes a cap sidewall. The cap sidewall can threadably and removably engage the neck section.

A protective bottle enclosure includes a base with a cylindrical base sidewall secured to a base bottom wall and an open top. The base sidewall includes at least one thread disposed thereon. The base bottom wall has a substantially planar bottom surface. A body section has a cylindrical body wall and a bottom opening. A shoulder section has a cylindrical shoulder wall including a taper. The shoulder section is disposed between the neck section and the body section. The body section can threadably and removably engage the base sidewall of the base. A removable cap includes a cap sidewall surrounding a cap cavity. A top wall is disposed above a cap opening, and the cap cavity extends between the top wall and the cap opening. The cap sidewall can threadably and removably engage the neck section and includes a knob and an extension.

A child-resistant closure for a container with an outer screw thread opening, including an outer cap with a first sidewall and a first top wall and an inner cap with a second sidewall and a second top wall, the inner cap being coaxially nested within the outer cap and being provided with an inner thread to screw the inner cap onto the container. The outer cap and the inner cap include a first cooperating engagement means, and a second cooperating engagement means wherein the second cooperating engagement means includes a plurality of strip-like elastic members wherein each strip-like elastic member is inclined relative to the first top wall and includes a reinforcing element arranged between the first or second top wall and the strip-like elastic member connected thereto.

A beverage container includes a first vessel, a second vessel, a cap assembly, a first conduit, and a second conduit. The first and second vessels are vertically stacked and define first and second internal cavities, respectively. The first vessel is disposed above the second vessel. A cap assembly is secured to a top of the first vessel. The cap assembly defines first, second, and third orifices. The first orifice establishes fluid communication with the first internal cavity. The first conduit establishes fluid communication between the second internal cavity and the second orifice. The second conduit establishes fluid communication between the second internal cavity and the third orifice.

A closure that remains coupled to a container after the upper portion of the closure has been rotatably removed from the container. The closure may include an attachment channel, which includes alternating segments of linear openings and frangible connections. The attachment channel may also include two hinge bridges that remain unbroken when one or more of the frangible connections are broken.

A transportable flask. The transportable flask includes a bottle, where the bottle is configured to hold a liquid beverage. The transportable flask also includes a cap, where the cap is configured to attach to the bottle and prevent removal of the liquid beverage when in position. The transportable flask further includes a first cup, where the first cup is releasably attached to the bottle and a second cup, where the second cup is releasably attached to the cap.

This disclosure provides new closure and finish structures suited for small and light-weight carbonated beverage packaging that provide surprisingly improved carbonation retention and greater shelf life, while still achieving light weight. This closure and finish presented herein are particularly suited to small PET containers for carbonated beverages, for example less than or about 400 mL and provide good carbonation retention and shelf life.

The present disclosure relates to modified conical centrifuge tubes and related methods.
