A cap made of synthetic resin coming into mesh with a mouth of a container is provided, wherein the cap comprises a tubular member (3) made of synthetic resin, a ring (7) provided integrally with a lower end of the tubular member through easily rippable joint pieces (6), a multiplicity of engagement members (10) formed to extend obliquely upward from an inner lower end of the ring and to have a uniform thickness as a whole, the engagement members being each inclined along both sides thereof so as to spread toward its upper end and projected radially inward to have an arc-shaped bulged portion (9), junctions at which opposite upper side ends of the adjacent engagement members are integrally connected to each other, and thin films (13) formed to cover areas defined by the ring and the adjacent engagement members, and the container has a mouth provided with a screw-shaped groove (17) coming into mesh with the cap and an annular projection (18) formed below the screw-shaped groove and engaging the engagement members. There is also provided a cap wherein opposite upper side ends of the adjacent members are not connected to each other, and the thin films are formed to cover areas defined by the ring and the adjacent engagement members. An embrittled line (30) is formed to extend vertically across the ring, the engagement member, and/or the thin film.

A cap includes a main unit 11 fit onto the mouth of a double-walled container, a spout cylinder 12 provided on the main unit, an inner stopper 15 that is provided in the main unit 11, and a first inner valve 31. The inner stopper 15 includes a communicating part 29 that communicates with the inside of the inner container and the inside of the spout cylinder 12. The first inner valve 31 includes a first valve body 33 that covers the communicating part. The first valve body 33 has passage holes 35. The first valve body 33 being deformed from a closing position S toward an opening position O keeps acting as a partition between the communicating part 29 and the spout cylinder 12.

In order to provide a check valve capable of sufficiently suppressing the mixing of air into the container even if a certain impact is applied to the container and also capable of stably maintaining good pouring of the content, a check valve 10 of the invention is formed of rubber material and manufactured by integral molding. The check valve 10 has a tubular main body 1 having openings 1 a and 1 b at opposite ends, a lid 3 arranged to close one opening 1a of the main body 1, and a hinge 5 that connects the main body 1 and the lid 3. The lid 3 has a projection 3a on the side surface 3b, the projection 3a coming in contact with a peripheral edge of the opening 1 a of the main body 1.

摘要:
A hinge cap is provided which includes: a cap body having a top wall, a spout provided in the top wall and a side wall extending downward from a peripheral edge of the top wall; and an upper cap portion connected to the cap body via a hinge and capable of capping and uncapping the spout. The hinge cap is composed of a resin composition comprising polylactic acid and an aliphatic polyester resin other than the polylactic acid. The polylactic acid and the aliphatic polyester resin other than the polylactic acid are present in the resin composition in a mass ratio of (polylactic acid) : (aliphatic polyester other than polylactic acid) = 90:10 to 5:95.
