A connector for a self sealing fitment that includes a body, a lower flange, and a locking mechanism. The connector is configured to sealingly engage with a cap coupled to a spout of a flexible bag by sealingly engaging with a sealing membrane of the cap. The locking mechanism facilitates the maintaining of the same in the inserted configuration. A lockout collar is provided to preclude inadvertent and undesirable coupling between a connector and a sealing membrane of a cap.

A container with detachable suction straw is disclosed, including a container and a lid assembly covering the container. The lid assembly comprises walls defining a recess, guiding grooves that facilitate assembly and easy removal of the detachable sealed straw, a rotating axis concave joint, and guiding grooves where the detachable sealed straw and the elastomeric seal are housed. The detachable sealed straw contains positioning balls and a spout, the spout is designed to have a body that rotates on the concave surface of the rotating axis joint of the lid assembly, a passage for the flow of contents within the container, a spout lead-in portion, a blind hole for assembling the positioning balls, and a handle. The elastomeric seal fits tightly into the lid assembly.

Systems for measuring an ingredient are disclosed. A cap with a flexible silicone thread is configured to screw onto a threaded bottle and has a shaft and a slit. The cap has a rotatable filling section attached to the cap and configured to rotate to block the slit and prevent fluid communication between the threaded bottle and a dispensable volume or to expose the slit and allow fluid communication between the threaded bottle and the dispensable volume. A volume selector rotates to provide a largest and a smallest measurable volume. A lid covers the dispensable volume. A user rotates the rotatable filling section to fill the section with an ingredient. The user rotates it back, removes the lid, and dispenses the ingredient.
