Abstract: A packaging which enables a compressible container to be fully emptied by pressing the fingers against the body thereof. The packaging has four parts, namely: a body having a vent hole, a container with a discharge hole, a flexible pouch and a cap. The aforementioned flexible pouch retracts and moves back completely until it is applied against the inner wall of the container. When the user exerts pressure on the body of the packaging while blocking the vent hole with a finger, all of the contents are discharged from the flexible pouch gradually and without effort, by compressing the air contained in the body. The device can be adapted to all compressible packaging for liquid, viscous or pasty products.

Abstract: Resealable caps and tops for directional pour spout containers currently available for liquid and semi-solid products are either a spout and cap design, in which the tip is cut off to pour or squeeze out the container contents, or a non-spout, hinged top-and-bottom design, which defines a flat surface with an opening. These designs have many limitations. For example, the closure portion of a conventional spout closure can become detached, leading to production line delays, lost tips in transit, product recall at the store level, loss of shelf life and potential chocking hazards to children and pets. The non-spout hinged, top-and-bottom design does not offer the directional dispensing capabilities. This invention addresses the shortcomings of conventional caps and tops by providing a one-piece directional pour spout container cap in which the base has an upwardly directed spout and a hinged flip top cap is attached to the spout.

Abstract: A water-squirting toy comprises a cylinder, a handle, and a flexible bag. The bag is arranged inside the cylinder and may stretch and shrink following the handle that is pulled and pushed to absorb water or squirt water for fun at play of repeated water absorption and squirting. The water-squirting toy absorbs and squirts water by using the flexible bag that stretches and shrinks instead of a conventional piston that is jostled, so simple structure, fewer parts, lower fabrication labor hour, and fabrication cost down is achieved. Further, easy operation and higher duration are achieved. The cylinder may be made of soft material to squirt in a bending status. The handle and the cylinder may be connected and formed into a bar-shaped assembly for fun at play.
