Container cap for package

A check valve of one embodiment includes a spout member which has a flow path inside, an urging member supported by an inner end portion of the spout member, a valve body connected to the urging member, and a cylindrical member having a flow path inside, and is provided with a valve seat portion on an inner circumferential face, the spout member is fixedly attached to the cylindrical member so that the valve body and the urging member are inserted into the cylindrical member and the valve body is urged to the valve seat portion by the urging member, and the flow path and the flow path communicate with each other to configure an outflow path through which the content in the vessel flows out.

Packaging container cap

A sealing mechanism for a container opening having a cylindrical opening disposed on a container body and a cap for sealing the cylindrical opening. The cap includes a screw-on cap body and an upper lid for sealing the cylindrical opening. The cap body and the upper lid are independent of each other so that the cap body can be rotated without rotating the upper lid and are engaged by a concave/convex portion. When the cap body is moved away from the container, the cap body slidably abuts on the upper lid, and pushes up the upper lid to open the cylindrical opening, and when the cap body moves toward the container, the cap abuts on the upper lid and pulls down the upper lid to re-seal the cylindrical opening.

Sealing mechanism for a cylindrical container opening using a cap having a cap body and an upper lid

An improved pour spout member having a base attached to a packaging bag, a tubular neck having a tip opening sealed by a sealing member, and a lid member having an upper end connected to the sealing member and covering an outer periphery of the tubular neck. The lid member includes expandable lid segments having upper ends connected to a portion integral with the sealing member and, between the expandable lid segments in a collapsed state and a portion integral with the tubular neck, there is provided a rotation locking mechanism enabling temporary restriction of the lid member.

Pour spout member for packaging bag

A spout assembly for a packaging bag for improving the prevention of oxidation to an inner content and discharging such content at a desired amount. The spout assembly mounted to the bag body includes a spool to move along the axial direction of the spout assembly and an urging member having an outer peripheral surface fixed to the inner peripheral surface of the spout assembly and adapted to urge the spool toward the bag body side. A check valve allows the inner content to flow only from the bag body side toward the mouth portion side. The urging member has a seat surface for the spool and the urging member presses the spool against the seat surface to shut off the flow of the inner content, and when an inner pressure of the bag body or a suction force of the mouth reaches a predetermined value, the spool separates from the seat surface.
