The disclosure provides an anti-pollution bottle cap comprising a cap body, a liquid drainage one-way valve and an air intake one-way valve. A liquid drainage hole and an air intake hole are disposed in the cap body and both communicated with an inside of the cap body. The liquid drainage one-way valve is disposed in a space enclosed by the cap body. The liquid drainage hole is blocked by the liquid drainage one-way valve in one way so as to be opened during toppling operation. The air intake one-way valve is disposed in the space enclosed by the cap body. The air intake hole is blocked by the air intake one-way valve in one way so as to be closed during toppling operation. In application, the anti-pollution bottle cap will be installed on a bottle for matched use, so that a user can normally drain liquid through the liquid drainage hole only by squeezing the bottle. When use is stopped, through blockage of the liquid drainage one-way valve to the liquid drainage hole, adherends on the body surface of the user are prevented from entering the bottle, contents will not be polluted, and the problem that an existing bottle cap is likely to pollute contents is practically solved.

A machine for manufacturing a closure that has: a workspace for receiving a blank, a rim punch arranged to engage a blank received within the workspace, a center punch arranged radially inside the rim punch, the center punch arranged to engage the blank received within the workspace to form a closure, and an ejection pin arranged to cause the center punch to move such that the closure disengages from the rim punch.

Closing system for bottles and small bottles and method for the use thereof for the opening of said bottles integrated by a single piece with three differentiated parts, two of them, inner threaded hole and screw (7), made of rigid material and joined by a pre-cut line, used as a base on which an elastic part (10) is overpressed. This elastic part (10) has some perimeter grooves (18) that, when fastening the screw (11) in the inner threaded hole (4) of the neck (3), presses the elastic part (10) and secures it against the walls of the bottleneck (3). The bottle can be opened by just lifting the covering half fins (9) and turning them in the opposite direction to the thread, so the elastic part (10) is decompressed and can be easily removed, leaving the bottle opened. All materials are food grade materials.

Plastic pressure container including a main body portion, a finish portion, and a closure assembly. The main body portion defines an interior space. The finish portion is unitary with the main body portion and defines a mouth in communication with the interior space. The finish portion has an inner surface, an outer surface and an upper rim proximate the mouth. The inner surface has an inner undercut defined therein proximate the upper rim. The outer surface has an outer undercut defined therein proximate the upper rim. The closure assembly is mounted to the finish portion in engagement with both the inner undercut and the outer undercut.

An overcap for a container for storing at least one tennis ball, the container extending along a longitudinal axis and having an open end. The overcap includes a body adapted for removably attachment to the open end of the tennis ball container. The body includes a peripheral rim for engaging an outer surface of the container at the open end, and a lip projecting from the peripheral rim toward the longitudinal axis. The peripheral lip extends over a portion of the open end of the tennis ball container. The lip defines a first opening.

A closure for use with a container in which the closure includes a polymeric top portion and a polymeric annular skirt portion. The skirt portion depends from the top portion. The skirt portion includes exterior and interior surfaces. The interior surface of the skirt portion includes crushable ribs and anti-rotational lugs. The crushable ribs are configured to be crushed when the closure is applied to the container so as to prevent or inhibit axial movement of the closure with respect to the container by forming an interference fit. At least one of the plurality of anti-rotational lugs prevents or inhibits rotational movement of the closure with respect to the container such that the closure remains on the container.

A furan can for containing a product includes a sealed container that contains the product and includes a furan resin selected from the group consisting of: poly (ethylene 2,5-furan dicarboxylate) (PEF), poly (butylene 2,5-furan dicarboxylate) (PBF), poly (trim ethylene furan dicarboxylate) (PTF), poly (propylene 2,5-furandicarboxylate) (PPF), and poly (neopentyl 2,5-furandicarboxylate) (PNF); and a release mechanism to open the container and access the product. The can may further include a generally cylindrical shell molded to have a sealed bottom and a straight wall that includes the furan resin; and a cap to seal the shell, the cap having the release mechanism and a rim that includes the furan resin; wherein the rim of the cap is bonded to the wall of the shell to releasably seal the product inside the can.
