A spray pump is disclosed. A spray pump according to one aspect of the present invention comprises: a housing having an inlet space and coupled to a container inlet; a housing cover coupled to an upper end of the housing; a disk for opening or closing the housing according to a pressure of the inlet space; a valve movably inserted inside the housing cover and having a valve head, a valve passage formed in the valve head, and a valve body; a guide having a portion inserted into the valve body and another portion located outside the valve body, and including a guide passage corresponding to a flow passage through which content is discharged; a pump spring for providing an elastic force for urging the valve upward; a piston movably inserted into an outer circumferential surface of the guide, and opening or closing the guide passage by means of an upward and downward movement of the valve; a nozzle having a coupling protrusion coupled to the valve head and in communication with the valve passage; a valve ball positioned inside the nozzle and capable of closing the upper end of the valve passage; and a pump spring for urging the valve ball downward.

A non-metal pump type cosmetic container according to an embodiment of the present invention may efficiently process recycling after use. Also, Due to an operation of the elastic pump that is more flexible than a rigid metal spring, pumping may be achieved and thus a cosmetic material may be sensitively discharged even by a small force, leading to increases in tactile sensitivity and operational sensitivity. In addition, the structure of the elastic pump formed of resin having a relatively good deformation property is improved such that the elastic pump delicately may descend without being distorted during deformation, contributing to an improvement in product reliability according to a precise operation of each component.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and first and second loading cones received at opposing first and second ends of the slotted tubular spring element. The loading cones are axially compressible toward each other within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions.

Provided is an airless type mixing container for two kinds of contents capable of discharging all the contents, in which two kinds of substances may be separately accommodated and easily used by mixing the separately accommodated substances. The mixing container is configured such that an auxiliary container mounting member is mounted so as to be positioned on a content receiving part of a main container in which one of two kinds of contents is accommodated, and an auxiliary container in which the other of the two kinds of contents is stored is mounted on the auxiliary container mounting member, so that the two different kinds of contents are respectively stored. When a content discharge pumping member is deeply pressed, as the auxiliary container mounted on the auxiliary container mounting member is released from a body of the auxiliary container mounting member, the two kinds of substances are mixed together.
