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 system for sealing a beverage container includes a crown defining a bottom surface. A liner that includes an oxygen scavenger is coupled to the crown such that a top surface of the liner contacts the bottom surface of the crown. The bottom surface of the liner supports printed indicia where the bottom surface of the liner and the printed indicia are exposed to a beverage contained in the beverage container.

The disclosure relates to a crown cap for attachment to a mouth opening of a container body comprising fibers, and for closing the mouth opening by means of the crown cap. The disclosure further relates to a container with a container body comprising fibers and having a mouth opening and with a crown cap, wherein in a closure position the crown cap is attached to the mouth opening and closes the container body. In addition, the disclosure relates to a container body comprising fibers with a mouth opening that can be closed with a crown cap. The disclosure further relates to a method for arranging a crown cap on a container body comprising fibers, wherein the method comprises holding the container body and attaching the crown cap to the mouth opening, and to a device for arranging a crown cap on a container body comprising fibers.
