TH43704A3 - A container containing a hand pump - Google Patents

Abstract

DC60 (21/10/42) The purpose of this invention is to prevent outside air from entering the bypass section. Pass, when air is introduced into the container to prevent negative pressure and cause discharge function A fixed and uniform liquid is released in the upside-down position of the container, for such purposes the container Containing a hand pump will also be provided along with a 20 commutating valve unit to switch the delivery. Liquid to hand pump 1 in response to changes in the position of the container from the upright position Upside down or vice versa so that the container can be used to discharge liquid even in The upside-down position in such a container. External air inlet to container 50 for protection. The negative pressure protection has an opening per container 50 at the rear of the 40 cap unit. The commutator valve 20 is attached to the cover 40 from the bottom in a forward tilted position to allow outside air to rise. This will also make it easy for the check valve of the commutator valve unit 20 to sit firmly on the valve seat. The purpose of this invention is to prevent outside air from entering the bypass section. Passes when air is introduced into the container. To prevent negative pressure and to cause exact and consistent liquid discharge function in the upside-down position of the container to point Such a container containing a hand pump will also be provided with the unit. Interchangeable valve 20 to switch the delivery The liquid is transferred to the hand pump 1 in response to changes in the position of the container from an upright position, upside down, or vice versa, so that the container can The car is used to discharge liquid even in Inverted position in The container has external air inlet to container 50 for protection. The negative pressure protection has an opening per container 50 at the rear of the 40 cap unit. The commutator valve 20 is attached to the cover 40 from the bottom in position. Tilt forward so that the outside air that ascends to the surface of the liquid in the form of air bubbles does not approach the vents in the liquid. Of 20 switching valve units will also cause Easy for the check valve of the commutating valve unit. 20 sits firmly on the valve seat.
