Abstract

The present invention relates to a dual content mixing container, and the dual content mixing container according to the present invention is constituted in such a way that a second content substance housed in a storage chamber is mixed with a first content substance housed in a main container body by moving a hermetically sealing member downwards by means of action whereby a rotating cap is rotated, and thus the invention affords convenience to the user as the first and second content substances can be mixed by means of a simple action.

First claim

What is claimed is:

1. A dual content mixing container comprising:
a main container body storing first contents;
an inner cap encircling an upper portion of the main container body and fixed to the main container body, the inner cap comprising a storage chamber having a space for storing second contents, and a pair of sloped portions that protrude opposite each other at an inner circumferential surface of the inner cap;
a rotation cap encircling the inner cap on an upper portion of the container body and coupled to be able to be rotated;
a sealing member closing a lower end of the storage chamber of the inner cap and configured to descend when the rotation cap is rotated;
a pump support body interlocked with an inner surface of the rotation cap inside the rotation cap and configured to rotate when the rotation cap is rotated, the pump supporting body further comprising a pump combining tube combined with a pumping member, and a securing plate encircling the pump combining tube and secured on an upper end of the inner cap;
a pressurizing member combined with an upper portion of the sealing member and configured to rotate together with the pump support body while interlocked, the pressurizing member comprising a pair of descending guide protrusions which respectively contact a lower end of the pair of sloped portions, such that the descending guide protrusions thereby rotate with the rotation cap when the rotation cap is rotated and move from a top dead point to a bottom dead point along a lower end of the sloped portions, respectively, causing the sealing member to descend;
the pumping member combined with the pump support body and configured to discharge contents by a pumping operation; and
a button member combined with an upper portion of the pumping member and configured to operate the pumping member, the button member comprising a discharging hole for discharging contents;
wherein a pair of rotation limiting grooves opposing each other are formed at an outer circumferential surface of the inner cap to limit a rotation range of the rotation cap, and a pair of rotation limiting protrusions are formed at an inner circumferential surface of the rotation cap, the pair of rotation limiting protrusions movable inside the pair of rotation limiting grooves, respectively,
wherein a reverse rotation preventing protrusion is formed at each of the pair of rotation limiting grooves for preventing the rotation cap from being rotated in a first direction while being rotated in a second direction opposite the first direction,
wherein a vertical guide groove is formed longitudinally at both sides of an inner circumferential surface of the pressurizing member, and
wherein a vertical guide protrusion is formed at both sides of an outer circumferential surface of the pump combining tube, the vertical guide protrusions coupled to the vertical guide grooves, respectively, so as to guide a vertical movement of the pressurizing member.
