In a conventional mill container, a gap between grinders is set according to the contents. However, there is a problem that the gap between the grinders varies due to the molding variation of the grinder, and as a result, the size and discharge amount of the pulverized particles are likely to vary.
Therefore, the present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a mill container in which variations in the size and discharge amount of pulverized grains are unlikely to occur.

The first means according to the present invention for solving the above technical problem includes: a bottomed container main body that contains contents; and a fixed blade that is attached to the mouth of the container main body along the inner circumferential surface circumferential direction. A mill container comprising a formed first grinder and a second grinder in which a movable blade is formed to be rotatable around a central axis in a form facing the fixed blade,
The first grinder is attached to the mouth portion of the container body via a cylindrical adapter cap with both ends open, and the second grinder is corrugated on the peripheral edge of the one-end open cylindrical rotator covering the adapter cap. attached to the top plate portion which are connected by the body, characterized in that it is configured to be able to the second grinder is displaced along the center axis direction amplitude within a predetermined range.

In the above configuration, the second grinder is configured to be displaceable with a swing width within a predetermined range along the central axis direction with respect to the first grinder. As a result, even when the gap between the grinders (between both blades) is formed larger than a predetermined value (even when the particle size of the contents is smaller than the gap between the grinders), the second grinder is displaced downward, and the grinder By narrowing the gap therebetween, the contents can be drawn between the grinders and uniformly pulverized. On the other hand, even when the gap between the grinders (between the two blades) is formed smaller than the predetermined value (even when the particle size of the contents is larger than the gap between the grinders), the second grinder is displaced upward and between the grinders. As the gap increases, the contents can be drawn between the grinders and pulverized.
Further, since the swing width (displacement amount) of the second grinder is configured to be regulated within a certain range, the discharge amount of the pulverized particles is also regulated within a certain range.
Furthermore, since the second grinder is displaced in the direction of the central axis in addition to the rotation operation, the contents can be pulverized more finely.
As described above, in the above-described configuration according to the present invention, the influence of the grinder forming variation or the like on the variation in the size and the discharge amount of the pulverized particles is preferably canceled, and the size and the discharge amount of the pulverized particles become uniform.

  In the above configuration, the second grinder can be rotatably attached to the first grinder with the movable blade facing the fixed blade.

  In the said structure, it becomes possible to displace the 2nd grinder attached to a top-plate part suitably along a center axis direction.

Second means according to the present invention, the working regulations cover having a discharge opening in the rotary body is movable up and down, in that.

  In the above configuration, it is possible to suitably regulate the maximum displacement amount with respect to the upper side (discharge direction) of the second grinder.

The third means according to the present invention is that a peripheral rib is provided at an upper end portion of the first grinder.

  In the said structure, it becomes possible to regulate suitably the maximum displacement amount with respect to the downward direction (container main body side) of a 2nd grinder.

The 4th means which concerns on this invention exists in the clearance gap between the said fixed blade and the said movable blade being set to the range of 0.0 mm-0.1 mm.

  With the above configuration, it is possible to make the size of the pulverized particles uniform while securing the discharge amount.

  According to the mill container of the present invention, the second grinder having a movable blade is configured to be displaced with a swing width within a predetermined range with respect to the first grinder having a fixed blade. For this reason, it is preferable to cancel the influence of the variation in grinding of the grinder on the variation of the size and discharge amount of the pulverized particles, and to keep the discharge amount of the pulverized particles within a predetermined range while keeping the size of the pulverized particles within the predetermined range. It becomes possible to suppress.

  Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the drawings.

FIG. 1 is an explanatory cross-sectional view of a main part showing a mill container 100 of the present invention.
The mill container 100 includes a container main body 10 for storing contents, a first grinder 20L and a second grinder 20U for pulverizing the contents, and an adapter cap for attaching the first grinder 20L to the mouth portion 11 of the container main body 10. 30, a rotating body 40 for rotating the second grinder 20 </ b> U so as to face the first grinder 20 </ b > L, an operation restricting cover 50 for restricting the maximum amount of upward displacement of the second grinder 20 </ b> U, and rotation An overcap 60 that seals the discharge ports of the body 40 and the operation restriction cover 50 is provided. Note that the maximum downward displacement amount of the second grinder 20U is regulated by the circumferential rib 20Lc provided on the upper portion of the first grinder 20L. The rotating body 40 will be described later with reference to FIG.

  The container body 10 is, for example, a transparent synthetic resin container, a metal container, or a glass container.

  In the first grinder 20L, a serrated blade (for example, a saw blade or a triangular blade) is formed as a fixed blade 20La along the circumferential direction of the inner peripheral surface. On the other hand, the lower half portion of the second grinder 20U constitutes a screw mechanism that draws the contents between the grinders, and the upper half portion constitutes the movable blade 20Ua in a form facing the fixed blade 20La. Therefore, when the second grinder 20U rotates relative to the first grinder 20L, the contents are drawn between the grinders and crushed by the movable blade 20Ua and the fixed blade 20La. In addition, the form of each blade of the 2nd grinder 20U and the 1st grinder 20L is not limited to this embodiment, and when the 2nd grinder 20U rotates relatively with respect to the 1st grinder 20L, the content is between grinders. Any structure may be used as long as the movable blade 20Ua and the fixed blade 20La are pulverized.

  The adapter cap 30 is divided into two by a flange portion 31, an upper cylindrical side wall 32 is provided above the flange portion 31, and a lower inner cylindrical side wall 33 and a lower outer cylindrical side wall 34 are provided below the flange portion 31.

  The flange portion 31 receives the first grinder 20L on its upper surface and is joined to the upper end of the mouth portion 11 of the container body 10 on its lower surface.

  On the inner peripheral surface of the upper cylindrical side wall 32, vertical ribs 32a for fitting into the notches 20Lb of the first grinder 20L are provided at equal intervals. A protrusion 32aa projecting radially inward is formed below the vertical rib 32a. Therefore, each vertical rib 32a is fitted into a notch 20Lb provided on the outer peripheral surface of the first grinder 20L to restrict the movement in the rotation direction, and further, the vertical rib 32a and the notch 20Lb are provided with an allowance. Thus, the first grinder 20L is fixed to the adapter cap 30.

  A circumferential convex portion 32 b is formed on the outer peripheral surface of the upper cylindrical side wall 32, and is fitted into a circumferential concave portion 41 c (FIG. 2B) of the cylindrical side wall portion 41 of the rotating body 40.

  A female threaded portion 33 a is formed on the inner peripheral surface of the lower inner cylindrical side wall 33, and is screwed into a male threaded portion 11 a formed in the mouth portion 11 of the container body 10.

  A step portion 34 a that receives the lower end of the rotating body 40 is formed at an intermediate height position of the lower outer cylindrical side wall 34.

The operation restricting cover 50 is screwed into the rotating body 40 and tightens or loosens the screw to adjust the clearance (clearance) between the back surface and the top plate portion 42 (FIG. 2) of the rotating portion 40. Although not shown, the top plate portion of the operation restriction cover 50 is provided with a discharge port, and is the opening area S ₅₀ of the discharge port equal to the opening area S ₄₀ of the discharge port of the rotator 40 or not? Or it is set so that it may become small. Therefore, the discharge amount of the pulverized powder discharged from the discharge port of the rotating body 40 is once restricted by the operation restriction cover 50. Therefore, the final discharge amount of the pulverized powder discharged from the operation restriction cover 50 is determined by the degree of overlap between the discharge port of the rotating body 40 and the discharge port of the operation restriction cover 50.

  The overcap 60 is concavo-convexly fitted to the rotator 40 and seals the discharge ports of the rotator 40 and the operation restriction cover 50 to prevent deterioration of the contents due to air.

FIG. 2 is an explanatory view showing a rotating body 40 according to the present invention. FIG. 2A is a top view, and FIG. 2B is a cross-sectional view taken along line AA of FIG. For convenience of explanation, the second grinder 20U is also displayed in an overlapping manner in FIG.
The rotating body 40 includes a cylindrical side wall portion 41, a top plate portion 42, and a corrugated plate structure 43 that connects them.

  As shown in FIG. 2 (b), the cylindrical side wall portion 41 has a two-stage outer peripheral surface, and is concavo-convexly fitted to the male screw portion 41 a for screw fitting with the operation regulating cover 50 and the overcap 60. For this reason, peripheral ribs 41b are formed. On the other hand, on the inner peripheral surface of the cylindrical side wall portion 41, a peripheral recess 41 c for engaging with the adapter cap 30 in an uneven manner is formed.

  A hollow cylindrical portion 42a is erected on the back surface of the top plate portion 42, and a circumferential recess 42aa is formed on the lower outer peripheral surface thereof to be fitted to the circumferential projection 20Ub of the second grinder 20U. A cutout portion 42ab is formed on the outer peripheral surface, and a peripheral rib 42b is formed on the back surface of the top plate portion 42 and outside the hollow cylindrical portion 42a. Therefore, the second grinder 20U is restrained from moving in the vertical direction by the circumferential recess 42aa, restricted from rotating around the hollow cylindrical portion 42a by the notch 42ab, and further restrained from moving in the horizontal direction by the circumferential rib 42b. The top plate part 42 is assembled integrally. Accordingly, the second grinder 20U is displaced integrally with the top plate portion 42.

  The corrugated plate structure 43 is a structure that connects the cylindrical side wall portion 41 and the top plate portion 42. Since the corrugated structure 43 has a corrugated structure (for example, a bellows structure), it has a certain degree of flexibility. As a result, the top plate portion 42 and the second grinder 20U can be appropriately displaced in the vertical direction by the elastic effect of the corrugated plate structure 43. By setting the gap between the grinders as small as 0.0 mm to 0.1 mm, it corresponds to the small particle size of the contents, and the contents can be drawn between the grinders and pulverized. On the other hand, even when the particle size of the contents is larger than the gap between the grinders, the second grinder 20U is displaced upward, and the gap between the grinders expands, so that the contents can be drawn between the grinders and pulverized. . Thus, the upper part of the rotating body 40 has a bellows structure, and by operating the rotating body 40, the contents enter between the upper and lower sides of the grinder, and the movable blade 20 Ua is fixed to the fixed blade 20 La by the elastic effect of the corrugated plate structure 43. It can be crushed while moving moderately. At that time, as will be described later, by providing an operation restriction cover 50 above the rotating body 40, the displacement amount of the second grinder 20U (movable blade 20Ua) is restricted, and the size and discharge amount of the pulverized particles are controlled. regulate.

FIG. 3 is an explanatory view showing the operation of the operation restriction cover 50 according to the present invention.
A gap (clearance) between the back surface of the operation regulating cover 50 and the top plate surface of the top plate portion 42 is the maximum displacement amount of the top plate portion 42 and the second grinder 20U (movable blade 20Ua).
As shown in FIG. 3A, when the operation restricting cover 50 rotates clockwise with respect to the rotating body 40, the operation restricting cover 50 is lowered and the clearance C1 becomes narrow, and the maximum displacement amount of the movable blade 20Ua. Becomes smaller. On the other hand, as shown in FIG. 3 (b), when the operation restriction cover 50 rotates counterclockwise with respect to the rotating body 40, the operation restriction cover 50 rises and the clearance C2 becomes wider, and the movable blade 20Ua The maximum amount of displacement increases.

4 and 5 are explanatory views showing the operation of the mill container 100 of the present invention. FIG. 5 shows a state in which the portion A in FIG. 4 is rotated by 90 ° around the central axis CL.
For example, when the container body 10 is gripped and the rotating body 40 is rotated, the content is drawn between the grinders by the screw action of the second grinder 20U, and the movable blade 20Ua of the second grinder 20U and the first grinder 20L are fixed. It is crushed by the blade 20La. When the contents are crushed, the second grinder 20U is displaced along the vertical direction (axial direction) by the elastic action of the corrugated plate structure 43, as shown in FIG.

  FIG. 5A shows a state in which the second grinder 20U has been displaced maximum in the upward direction. The top plate portion 42 of the rotating body 40 hits the back surface of the operation restriction cover 50 and restricts the operation of the second grinder 20U. On the other hand, FIG. 5B shows a state in which the second grinder 20U is displaced maximum in the downward direction. The corrugated plate structure 43 hits the circumferential rib 20Lc formed above the first grinder 20L and regulates the operation of the second grinder 20U.

  As described above, according to the mill container of the present invention, the second grinder 20U having the movable blade 20Ua can be displaced with respect to the first grinder 20L having the fixed blade 20La with a swing width within a predetermined range. Has been. For this reason, the influence of the variation in the shape of the grinder on each variation in the size and discharge amount of the pulverized particles is preferably canceled out, and the size of the pulverized particles is kept within the predetermined range while ensuring the discharge amount of the pulverized particles within the predetermined range. It becomes possible.

  The mill container of the present invention is suitably applied to a container for pulverizing granular hard plant fruits such as sesame and pepper.
