Abstract: A spout affixed to a fluid-dispensing container that allows unobstructed fluid flow until the spout end becomes immersed. The anti-spill and self-venting features are achieved by establishing an airway from the top of the spout and extending into the container in the form of a flexible tube. A float attached to the tube lifts the end to the surface of the fluid within the container. As fluid exits, air enters the container allowing for smooth fluid discharge. When the spout end becomes immersed, fluid is drawn into the vent instead of air. An air vacuum develops that is equal to fluid pressure within the container. Fluid flow is interrupted until the container is returned to an upright position. This allows for fluid to evacuate from the floating vent and back into the contained. The self-venting feature of the spout is then reestablished.

Abstract: A ram plate which allows easy lifting and dropping of the plate even when a complete seal has been made with high-viscosity liquids inside a barrel. The system contains two alternative methods of depressurizing the internal liquids in order to more efficiently avoid vacuum and suction effect when the user attempts to raise the plate. The bleed stick components of the plate are completely independent of vent ports components. Such bleed stick components are levers which, when depressed, will move a cover and expose the internal liquids to outside air pressure via air vents. The vent port components operate through both gravity and potential energy of an internal spring, which place a given amount of downward pressure on a pneumatic cylinder which may or may not be enough pressure to move the cylinder and expose a vent to the outside atmosphere pressure.

Abstract: A valve element may be configured to be mounted in an air intake passage of a container. The valve element may be at least partially elastically deformable. The valve element may include a valving member configured such that, when vacuum pressure inside the container is less than a predetermined threshold differential from atmospheric pressure, the valving member is in sealed contact with a seat formed on the container. The valving member may also be configured such that the valving member moves away from the seat when the predetermined threshold differential is reached, so as to allow air to be taken into the container. By elastic return, the valving member may return to a position in sealed contact with the seat when the vacuum pressure inside the container drops back to less than the predetermined threshold differential. The valve element may be placed in a functional configuration via an elastically irreversible modification thereof during mounting.

The armature of the liquid outlet valve and the armature of the air inlet valve are arranged consecutively in their longitudinal direction of displacement.

Abstract: In this invention there is provided a pouring vessel of the squeezable, delaminated bottle type, which can be squeezed smoothly to the last moment of discharge operation so that little content remains in the vessel. The vessel or container of a delaminated bottle type comprises the outer shell layer that forms a squeezable outer container and the inner layer that forms an inner container for receiving its content inside and capable of being deflated and deformed inward with the decrease in inner pressure; and the container is also provided with a discharge cap. In this configuration, a pair of vertically extending adhesive resin strips is formed by adhering the outer shell layer and the inner layer over the roughly entire height of the container. The relationship of the peripheral length between the two adhesive resin strips to the width of each strip is determined to give such a range that the inner container can be almost completely deflated and deformed.

The fin is arranged below and apart from the liquid-passage hole in the bottom plate in horizontal direction. The side plates are arranged in vertical direction, and put the liquid-passage hole and the fin between them. When a hot drink is poured into the container body to increase the inner pressure of the container body, the fin and the side plates can obstruct the exhausting flow rate of the inner pressure so that the inner pressure cannot be exhausted rapidly. When the fin is bent towards the liquid-passage hole due to the increased inner pressure, the inner pressure can be exhausted efficiently according to its magnitude.

Abstract: A mechanically pressurized aerosol dispensing system comprising a cap which houses a piston, an actuator moveably attached to the cap, forming together with the cap a dispensing head assembly, and an expandable elastic reservoir. The system is fitted over a standard container holding a liquid product, and includes a dip tube assembly to draw liquid into the dispensing head assembly, where the contents are released through the dispensing head assembly, via the aerosol nozzle and valve. A twist of the threaded cap raises a piston, thereby opening a charging chamber within the dispensing head assembly. This creates a vacuum with the resulting suction pulling the product up through the dip tube to fill the charging chamber. Twisting the cap in the opposite direction lowers the piston in a downstroke which closes the charging chamber, forcing the product into the expandable elastic reservoir where it is then discharged through the nozzle.
