Abstract: A closure for removably sealing a container and for attaching to external articles having an external hooking device. The closure includes a container cap configured to removably engage the container and having a strip engaging portion formed proximate an end of the cap. The closure includes an attachment member that has a resilient hooking strip extending from the lid to define a hooking aperture therebetween. The attachment member has a cap engaging portion formed adjacent an end thereof and releasably engaged to the strip engaging portion. The engaging portions are configured such that the cap engaging portion is releasable from engagement by applying disengaging force upon any portion of the hooking strip.

Abstract: A bottle cap including a cover having a front end defining a pair of substantially parallel flanges extending generally perpendicularly from the cover, a deformable panel extending between the flanges, and an opposed rear end defining a pair of body-engaging hinges extending from a portion thereof. The cap includes a body having a top portion defining an outwardly projecting spout at one end and an inwardly projecting cavity at another end that may pivotally receive the body-engaging hinges for rotating the cover about an x-axis relative the body when attached thereto. Pressure applied to the flanges causes the panel to resiliently deform and disengage from the body allowing the cover to transition from a closed position mating the front end of the cover with the top portion of the body for providing a fluid-tight seal therebetween, and an open position retaining the rear end of the cover against the body.
