The locking connection is provided by two radially outwardly protruding locking beads, which are spaced apart from one another in the vertical direction. The locking beads are designed with an insertion rounding on the reservoir side and with a substantially horizontal contact surface with respect to the longitudinal section on the head piece side.

The disclosure discloses a dual-spring all-plastic vacuum pump which includes a base and a pressing head. A feeding hole is formed in a bottom of the base, an accommodating cavity is defined by assembly of the pressing head and the base, the feeding hole is in communication with the accommodating cavity, and a limiting cover, a plastic one-way spring, a discharging member and a plastic reset spring are disposed in the accommodating cavity. The limiting cover surrounds the feeding hole, a guide hole in a top of the limiting cover is in communication with an interior of the limiting cover, the plastic one-way spring is clamped between the base and the limiting cover, a fixed end of the plastic one-way spring is in connection and communication with the feeding hole, a stressed end of the plastic one-way spring is in communication with the guide hole, and the fixed end and the stress are opposite. The discharging member is disposed between the pressing head and the limiting cover, the discharging member penetrates through the guide hole and is in communication with the stressed end, and the discharging member is configured to receive materials to the pressing head for output. The plastic reset spring is clamped between the discharging member and the limiting cover. Pressing of the pressing head is configured to push the discharging member to compress the plastic one-way spring. By means of the solution, a metal spring is replaced with a plastic spring, and the problem that an existing pump head is inconvenient to directly recycle is practically solved.

Disclosed is a refillable cosmetic container including a container body provided with a main body of which an one side is opened; a refillable container part detachably coupled to the main body and in which a cosmetic liquid is stored; a support part coupled to the other side of the main body; and a pumping driving part coupled to the support part to discharge the cosmetic liquid stored in the refillable container part to the outside of the refillable container part, wherein the refillable container part includes a refillable container body detachably coupled to the main body and a shifter part detachably coupled to the refillable container body and penetrated with a tube member of the pumping driving part, and a film is provided between the refillable container body and the main body to be easily separated when the refillable container body is separated from the main body.

Disclosed is a tubeless dispenser container. A tubeless dispenser container according to one aspect of the invention is a tubeless dispenser container for dispensing a content held in a filling space and includes: a bottle part in which the filling space is formed and which has a supply hole, for allowing a flow of the content, and an air hole, for allowing an inflow of air, formed in its upper surface; a connector part coupled to an upper portion of the bottle part to spatially separate the supply hole from the air hole; and a pump part that is secured to a designated position of the connector part and configured to suction and dispense the content supplied through the supply hole, where a supply channel connecting a lower portion of the filling space with the supply hole may be formed in the bottle part.

A pump for dispensing a fluid, has a pump head, a piston with a piston body, a pump chamber provided by a pump chamber part, an inlet valve and an outlet valve. The piston body is moveable relative to the pump chamber. The piston body is tube-like, providing a channel for delivering the fluid from the pump chamber via the outlet valve to an outlet opening in the pump head. The outlet valve is a valve body cooperating with a sealing rim formed by an opening in an outlet channel of the pump head. The piston body has a sealing lip for with an inner surface of the pump chamber body. The pump head is moveable relative to the piston body providing an opening stroke for the outlet valve, wherein the valve body moves axially in the opposite direction into a part of the outlet channel above the valve body.

A dispenser for discharging flowable compounds has a reservoir for holding the compound and a dispensing pump. The dispenser has a longitudinal axis. The dispensing pump has an inflow and an outflow channel, a pumping chamber which is delimited on the inflow and outflow sides by valves, and a head piece. The head piece has a dispensing opening. A pumping part can be moved relative to a cup part against an elastic force of a restoring device in order to achieve a pumping stroke, and the head piece is coupled to the pumping part with respect to motion such that a motion of the head piece from a completely depressed position to a reachable extension height corresponds to the pumping stroke. A variable limiting device is provided for variably limiting the pumping stroke and a change in the pumping stroke corresponds to a change in the extension height.
