Powdered raw material, bottle cap and container with bottle cap

Abstract

Provided is a powdered raw material, which is housed in a housing portion ( 12 ) of a type of a bottle cap 1 which has the housing portion ( 12 ) that houses the powdered raw material, and of which the housing portion ( 12 ) is opened by an uncapping operation, and then causes the raw material to be released into the bottle. Using a multi-functional powder property measuring instrument multi-tester, the powdered raw material is dropped onto a watch glass from a powder falling point, a dropped mass and a mass on the watch glass are measured, and a degree of dispersion which is obtained from the following formula (1) is equal to or more than 5% and equal to or lower than 40%. degree of dispersion[%]=(dropped mass−mass on the watch glass)/the dropped mass×100  (1)

 wherein using a multi-functional powder property measuring instrument multi-tester, the powdered raw material is dropped onto a watch glass from a powder falling point, a dropped mass and a mass on the watch glass are measured, and a degree of dispersion which is obtained from the following formula (1) is equal to or higher than 5% and equal to or lower than 40%.
   degree of dispersion[%]=(dropped mass−mass on the watch glass)/the dropped mass×100  (1)
 
   
     
     
         2 . The powdered raw material according to  claim 1 ,
 wherein a degree of compaction which is calculated by the following formula (2) is equal to or higher than 30% and equal to or lower than 60%.
   degree of compaction[%]=(compact bulk density−loose bulk density)/compact bulk density×100  (2)

 wherein a particle diameter D 50  is equal to or higher than 3 μm and equal to or lower than 15 μm.   
       (Here, D x  represents a particle diameter of which a cumulative mass distribution becomes X % in a particle size distribution measured using a laser diffraction-scattering particle size distribution analyzer.) 
     
     
         4 . The powdered raw material according to  claim 3 ,
 wherein a uniformity which is defined by a (particle diameter D 60 )/(particle diameter D 10 ) is equal to or lower than 5.   
     
     
         5 . The powdered raw material according to  claim 3 ,
 wherein a particle diameter D 10  is equal to or higher than 1 μm.   
     
     
         6 . The powdered raw material according to  claim 3 ,
 wherein a particle diameter D 90  is equal to or lower than 50 μm.   
     
     
         7 . The powdered raw material according to  claim 3 ,
 wherein a standard deviation sigma of the particle size distribution is equal to or lower than 15 μm.   
     
     
         8 . The powdered raw material according to  claim 1 ,
 wherein a loose bulk density is equal to or higher than 0.1 g/cm 3  and equal to or lower than 0.4 g/cm 3 .   
     
     
         9 . The powdered raw material according to  claim 1 ,
 wherein a compact bulk density is equal to or higher than 0.2 g/cm 3  and equal to or lower than 0.8 g/cm 3 .   
     
     
         10 . The powdered raw material according to  claim 1 , comprising:
 one or more kinds of supplements selected from one group of vitamins, minerals, amino acids, fatty acids, dietary fibers, sugars, proteins, turmerics, and polyphenols.   
     
     
         11 . The powdered raw material according to  claim 10 ,
 wherein the supplement is vitamins.   
     
     
         12 . The powdered raw material according to  claim 1  which is used in foods and beverages. 
     
     
         13 . The powdered raw material according to  claim 1  which is used in pharmaceuticals. 
     
     
         14 . The powdered raw material according to  claim 1  which is used in cosmetics. 
     
     
         15 . A bottle cap comprising:
 an inner cylinder portion having a cylindrical housing portion of which one end face is closed and the other end face is open and which is inserted into an opening portion of the bottle;   an outer cylinder portion having an outer cylinder portion body into which the housing portion is inserted, of which one end portion is screwed into the inner cylinder portion and the other end portion is inserted into the opening portion of the bottle and which is screwed into the opening portion of the bottle; and   a bottom lid portion which closes the opening of the housing portion and is detachably fitted to an end portion of an opening side,   wherein the end portion of the opening side of the housing portion is projected from the other end portion of the outer cylinder portion body,   wherein the housing portion is driven by screwing the inner cylinder portion to an opening direction with respect to the outer cylinder portion body, the bottom lid portion is pulled out from the opening of the housing portion by the other end portion of the outer cylinder portion body, and thus, the housed material in the housing portion is dropped into the bottle, and   wherein the powdered raw material according to  claim 1  is included in the housed material.
