A dispensing pump includes a spring assembly and a locking arrangement to prevent the dispensing head from being deployed and/or actuated during shipment, stocking and pre-purchase handling. The dispensing pump includes a pump base, and a dispensing head having a piston stem. The spring assembly includes a slotted tubular spring element and first and second loading cones received at opposing ends of the slotted tubular spring element. Various locking arrangements may include interacting rotatable lugs provided between the dispensing head and the pump base, snap beads to retain the piston and dispensing head in a secured shipping position, and recyclable locking rings disposed between the dispensing head and pump base which prevent an active dispensing head from being actuated.

A double container includes: an inner container adapted to store a given content therein and having a neck formed on top thereof; an outer container adapted to accommodate at least a portion of the inner container therein; a neck cap coupled to the neck of the inner container and having at least a portion accommodated in the inner container; pump assemblies coupled to top of the outer container, detachably coupled to the outer peripheral surface of the neck cap, having at least portions accommodated in the neck cap and inserted inside the inner container, and adapted to discharge the content therefrom; and a nozzle adapted to be pressurized by a user to discharge the content transferred from the pump assemblies through a discharge hole.

The present invention relates to a cosmetic container using an eco pump, and the eco pump effectively controls pressure acting on a space between a container body and a container lid, thereby preventing liquid leakage from the space between the container body and the container lid to the container lid. The cosmetic container using the eco pump includes a container body, a cover, a connection tube and a check valve which effectively block and release liquid contents discharged from the container body, an eco pump made of an elastomer material, and first to fourth cylinder members and a container lid discharging the liquid contents to the outside via a discharge path of a lid or blocking the liquid contents from the outside.

A double container includes: an inner container adapted to store a given content therein and having a neck formed on top thereof; an outer container adapted to accommodate at least a portion of the inner container therein; a neck cap coupled to the neck of the inner container and having at least a portion accommodated in the inner container; pump assemblies coupled to top of the outer container, detachably coupled to the outer peripheral surface of the neck cap, having at least portions accommodated in the neck cap and inserted inside the inner container, and adapted to discharge the content therefrom; and a nozzle adapted to be pressurized by a user to discharge the content transferred from the pump assemblies through a discharge hole.

A food pump with a safe outlet valve and an outer mounted spring comprises a pressing head (1), a primary column (2), a secondary column (3), a piston (4), a pump chamber (5), a spring (6) and a bottle locking cover (8). The pressing head (1) is installed on the primary column (2) which is arranged within the pump chamber (5). The secondary column (3) is connected to a lower end of the primary column (2). The piston (4) is sleeved on outer sides of the primary column (2) and the secondary column (3). A lock cover (9) capable of fixing the primary column (2) to the pump chamber (5) is fixed on the pump chamber (5). An outer side of an upper end of the lock cover (9) is provided with a cover flanging (91) which is turned outwards and then turned downwards to stretch. An upper end of the pump chamber (5) is inserted and fixed onto an inner side of the cover flanging (91). The lock cover (9) is provided with a locking opening (92) protruding upwards above the cover flanging (91). An outer side of the locking opening (92) is provided with an outer thread (93). An upper end of the primary column (2) is provided with a locking flanging (21) which is turned outwards and then turned downwards to stretch in order to be sleeved on the outer side of the locking opening (92). An inner side of the locking flanging (21) is provided with an inner thread (22) in threaded fit with the outer thread (93), such that a pump core composed of the primary column (2), the secondary column (3), the piston (4), the pump chamber (5), the spring (6), a glass bead (7) and the lock cover (9) can be stored and transported independently, thereby matching different pressing heads (1) and bottle locking covers (8) according to requirements, such that the use thereof is flexible.

The present invention concerns a system (1; 501; 601; 701; 801) for dispensing a fluid (L), comprising a container (C; C′) for the fluid (L) and a device (10; 210; 210′; 310; 410; 410′) for dispensing the fluid (L). The device (10; 210; 210′; 310; 410; 410′) comprises a collapsible chamber (20) which defines a volume (V) suited to receive a quantity of said fluid (L) to be dispensed. The chamber (20) is defined by a first portion (30) and a second portion (130) mutually coupled with each other, wherein the first portion (30) comprises an area connected to the container (C; C′) and wherein the second portion (130) comprises an area connected to the container (C; C′).

A trigger sprayer having a venting system including a piston bore and a vent bore at least partially contained therein, the vent bore including at least one vent port; a piston and vent piston are moveably seated in the piston bore and vent bore, respectfully, the vent piston including at least one annular seal and a vent path port, the vent path port and vent port in gaseous communication when the vent piston is actuated and moved over the vent port.

An all-plastic, continuous trigger sprayer is contemplated that avoids the use of metal parts, elastomers, or other disparate and non-recyclable materials. A reservoir diaphragm is provided within the sprayer head, interposed between the actuation mechanism and the outlet, so as to ensure a steady flow of dispensed fluid is delivered even after actuation has ceased.

A trigger-type liquid ejector including an ejector main body and a nozzle member. The ejector main body includes: a longitudinal supply tube portion; a trigger mechanism including a trigger portion; a reservoir cylinder; a reservoir plunger; and a reservoir valve. The longitudinal supply tube portion includes an outer tube and an inner tube. A recovery passage is provided between the outer tube and the inner tube. The reservoir valve is provided in the inner tube and configured to allow supply of a liquid from the longitudinal supply tube portion into the reservoir cylinder by being elastically deformed in the vertical direction.

A bladder-type dispensing pump (100) comprises a push nozzle (110) and a container cap (120), said nozzle (110) and cap (120) being interconnected. The push nozzle (110) is provided with a bladder portion (111). The bladder portion (111) is able to deform such that the volume of the internal cavity thereof may change. The bladder-type dispensing pump (100) is further provided with an elastic return mechanism. A portion of the elastic return mechanism is connected to or in contact with the bladder portion (111). When the bladder portion (111) is depressed so as to deform, the elastic return mechanism deforms with it, and when pressure acting on the bladder portion (111) is removed, the elastic return mechanism returns to its non-deformed state, causing the bladder portion (111) to reset.
