Storing and mixing device

Abstract

A storing and mixing system having a container and a cap is presented. The container includes a reservoir and a neck having a lip. The cap removably couplable to the neck of the container and has: a housing movably couplable to the neck by engaging an interior screw thread of the housing with the neck; a dispensing platform coupled to the housing by a plurality of ribs; and a plurality of peripheral dispenser openings between an exterior edge of the dispensing platform and the housing. The plurality of dispenser openings is configured to be plugged or unplugged by the lip of the neck. In an axial direction of the neck, a length of the lip is larger than or equal to a length of the interior screw thread of the container. Optionally, there are provided contact surfaces between the cap and the container to seal the dispensing platform from the ambient environment and from the interior of the container, when the cap is securely screwed onto the container.

         9 . The storing and mixing system as claimed in  claim 1  further comprising a seal ring disposed on a shoulder region of the container, and a bottom end of the housing of the storing and dispensing cap is capable of making abutting contact with the support when the lip of the neck is plugged to the dispenser openings, thereby creating an air-tight seal. 
     
     
         10 . A storing and mixing system, comprising:
 a container including a reservoir, a neck having a lip, and an external screw thread extending between the lip and a root of the neck;   a seal ring surrounding the neck and coupled to the neck of the container; and   a storing and dispensing cap removably couplable to the neck, the cap including:
 a housing movably couplable to the neck by engaging an interior screw thread of the housing with the external screw thread of the container; 
 a dispensing platform coupled to the housing by a plurality of ribs; and 
 a plurality of peripheral dispenser openings between an exterior edge of the dispensing platform and the housing, wherein the plurality of dispenser openings is configured to be plugged or unplugged by the lip of the neck;
