Description

[Technical Field]

[0001] The present invention relates to a mill container. [Background Art]

[0002] There is known a container in which moving teeth interlocked with an operating body and fixed teeth are arranged on the lower side of a container body, and the content is ground between the moving teeth and the fixed teeth and discharged as the operating body is pushed (Patent Document 1). [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Utility Model Registration No. 2519462 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] The container disclosed in Patent Document 1 has a disadvantage that when a predetermined content (for example, an oily granular material such as sesame) is ground, the grinding portion between the two grinding teeth (the moving teeth and the fixed teeth) is clogged.

[0005] An object of the present invention is to provide a mill container that can scrape off content fragments adhering to grinding teeth and is less likely to cause clogging. [Means for Solving the Problem]

[0006] The first means comprises: a container body 1 that incorporates a content storage portion A, has an opening O arranged on the lower side of the storage portion A, and is provided with a grinding table C on a part of the opening O, a movable body 12 disposed in the container body 1 and having moving teeth T for grinding the content by sandwiching the content between the movable body 12 and the grinding table C, and an operating body 20 for moving the movable body 12, This movable body 12 is configured to move between a first position P1, which is the original position, and a second position P2, which is the operating position, thereby causing the movable tooth T to be displaced vertically in the vicinity of the sliding base C. Below the gap between the grinding base C and the movable teeth T, a removal body 50 is provided to scrape off any residue adhering to the movable teeth (T) of the contents that are ground up when the operating body 20 is operated.

[0007] As shown in Figures 1 to 4, this device comprises a container body 1, a movable body 12, and an operating body 20. The container body 1, as shown in Figure 1(A) or Figure 4(A), has a storage compartment A for contents, an opening O located below the storage compartment A, and a sliding surface C provided in a part of the opening O. The movable body 12 is positioned inside the container body 1 and has movable teeth T for crushing the contents by sandwiching them between itself and the grinding surface C. The operating body 20 is the part used to move the movable body 12. As shown in Figures 1(B) and 1(C), or in Figures 4(B) and 4(C), the movable body 12 moves between a first position P1, which is the original position, and a second position P2, which is the operating position, thereby causing the movable tooth T to be displaced vertically near the sliding base C. Below the gap between the grinding base C and the movable teeth T, a removal body 50 is provided to scrape off any residue adhering to the movable teeth T from the contents that are ground up when the operating body 20 is operated. This structure allows for both grinding the contents and scraping off the contents (hereinafter referred to as "adhered material") that adheres to the movable teeth T as a result of the grinding, by operating the operating body 20. This eliminates the need for special work to scrape off fragments of the contents, and the removal process is completed simply by using the mill container in the normal way. This effectively prevents clogging near the opening O and makes it easy to use.

[0008] The second means is a rotating body 12A having the first means, wherein the movable body 12 has an arc portion 16 centered on the pivot axis 18 with respect to the container body 1, and a plurality of the movable teeth T are arranged in a circumferential direction on the surface of this arc portion 16. The attachment 50 is a wing member 50A having a wing plate 51 that sequentially strikes the plurality of movable teeth T from the outside of the arc portion 16.

[0009] In this configuration, the movable body 12 is a rotating body 12A having an arc portion 16 centered on a pivot axis 18 with respect to the container body 1, and having a plurality of movable teeth T arranged in a circumferential direction on the surface of this arc portion 16, as shown in Figure 1(A). According to this structure, in the process of rotating the rotating body 12A forward from the first position to the second position, as shown in Figure 1(B), the attachment body 50 is strongly pressed mainly against one tooth surface t1 of the moving tooth T, and in the process of rotating in the reverse direction from the second position to the first position, as shown in Figure 1(C), the attachment body 50 is strongly pressed mainly against the other tooth surface t2 of the moving tooth T, thereby improving the scraping effect of attached materials. This effect will be utilized in the third and fourth means. Furthermore, in this device, the attachment 50 is a wing member 50A having a wing plate 51 that sequentially strikes a plurality of movable teeth T from the outside of the arc portion 16. This structure allows for the scraping off of attached material one by one against multiple movable teeth T arranged in parallel on the arc portion 16 of the rotating body 12A, enabling a more thorough scraping operation.

[0010] The third means is a rotating body 12A having the first means, wherein the movable body 12 has an arc portion 16 centered on the pivot axis 18 with respect to the container body 1, and a plurality of the movable teeth T are arranged in a circumferential direction on the surface of this arc portion 16. The attachment body 50 is formed as a rotating brush 50B that rubs against the plurality of movable teeth T from the outside of the arc portion 16.

[0011] In this invention, the movable body 12 is a rotating body 12A having an arc portion 16 centered on a pivot axis 18 with respect to the container body 1, as shown in Figure 2(A), with a plurality of movable teeth T arranged in a circumferential direction on the surface of this arc portion 16, and the handle 50 is formed as a rotating brush 50B that rubs against the plurality of movable teeth T from the outside of the arc portion 16, as shown in Figures 2(B) and 2(C). With this structure, the frictional action of the rotating brush 50B from the outside allows for even and efficient scraping of contents fragments against the multiple moving teeth T arranged in parallel on the arc portion 16 of the rotating body 12A.

[0012] The fourth means is a rotating body 12A having the first means, wherein the movable body 12 has an arc portion 16 centered on the pivot axis 18 with respect to the container body 1, and a plurality of the movable teeth T are arranged in a circumferential direction on the surface of this arc portion 16. The arc portion 16 has through holes x provided between each of the movable teeth T. The attachment body 50 is formed as a rotating brush 50B that rubs the plurality of movable teeth T through the insertion hole x from the inside of the arc portion 16.

[0013] In this system, the movable body 12 is a rotating body 12A having an arc portion 16 centered on a pivot axis 18 with respect to the container body 1, as shown in Figure 3(A), with a plurality of movable teeth T arranged in a circumferential direction on the surface of this arc portion 16. Through holes x are provided between each of the movable teeth T in the arc portion 16. The handle 50 is formed as a rotating brush 50B that rubs against multiple movable teeth T through insertion holes x from the inside of the arc portion 16, as shown in Figures 3(B) and 3(B). With this structure, the frictional action of the rotating brush 50B from the inside allows for reliable and effective scraping of contents fragments from the root side against multiple movable teeth T arranged in parallel on the arc portion 16 of the rotating body 12A.

[0014] The fifth means comprises any of the second to fourth means and is equipped with fixed teeth U fixed to the sliding base C. Further, the movable body (12) is provided with a plurality of crushing projections S for crushing contents, the crushing projections being arranged above the fixed teeth U in a state where the rotating body 12A is at the first position.

[0015] In the present means, as shown in Fig. 1(A) and Fig. 2(A), fixed teeth U fixed to a grinding table C are provided, and the movable body 12 is provided with a plurality of crushing projections S for crushing contents, the crushing projections S being arranged above the fixed teeth U in a state where the rotating body 12A is at the first position P1. According to this structure, contents (such as sesame grains) accumulated on the fixed teeth U can be crushed and removed.

[0016] A sixth means comprises the first means, wherein the movable body 12 is a vertical rod-shaped lifting body 12B supported so as to be capable of lifting and lowering in a vertical direction, and a plurality of circumferential moving teeth T are arranged in parallel in the longitudinal direction of the lifting body as the moving teeth T, the grinding table C is supported inside the container body 1 and formed into a cylindrical body surrounding the lifting body 12B, the scraper member 50 is a squeezing ring 50C that protrudes downward and inward from a lower end of the grinding table C and is in pressure contact with a peripheral surface of the lifting body 12B.

[0017] In the present means, as shown in Fig. 4(A), the movable body 12 is a vertical rod-shaped lifting body 12B supported so as to be capable of lifting and lowering in a vertical direction. A plurality of circumferential moving teeth T are arranged in parallel in the longitudinal direction of the lifting body 12B as the moving teeth T. Further, the grinding table C is supported inside the container body 1 and formed into a cylindrical body surrounding the lifting body 12B. The scraper member 50 is a squeezing ring 50C that protrudes downward and inward from a lower end of the grinding table C and is in pressure contact with a peripheral surface of the lifting body 12B. According to this structure, adhered substances can be scraped off uniformly and efficiently from the entire peripheral surface of the rod-shaped lifting body 12B.

[Best Mode for Carrying Out the Invention]

[0020] Figure 1 shows a mill container according to a first embodiment of the present invention. This container consists of a container body 1, an operating member 10, and a bottom member 30. However, these structures can be modified as appropriate. Each of these components can be formed from, for example, a synthetic resin material.

[0021] The container body 1 is a component that has a storage compartment A for contents inside, an opening O located below the storage compartment A, and a sliding surface C provided in a part of the opening O. In this embodiment, the container body 1 is formed by inverting a container body 2, which has a bottomed cylindrical body (not shown) from which a mouth and neck portion 2a protrudes, and extending downwards from the mouth and neck portion 2a, a main cylindrical body 3 and an inner sub-cylindrical body 6. However, these structures can be modified as appropriate. In this embodiment, the storage section A is formed by the inside of the container body 2 and the connecting passage a shown in Figure 1(A), which will be described later. Container 1 can store various foods that require grinding (such as sesame seeds), and other items.

[0022] In this embodiment, the main cylinder 3 is formed by extending a roughly rectangular lower cylinder portion 3L from a cylindrical upper cylinder portion 3U fitted to the outer surface of the neck portion 2a via a stepped wall portion k. In the illustrated example, a flange portion 6m attached to the upper end of the inner sub-cylinder 6 is sandwiched between the stepped wall portion k and the end face of the neck portion 2a. In the illustrated example, the inner surface of the upper cylindrical portion 3U is provided with a female threaded portion m1 that engages with the male threaded portion m2 of the neck portion 2a, as shown in Figure 1(A). The lower end of the inner surface of the lower cylindrical portion 3L is provided with a projection receiving portion n2 that engages with an engaging projection (undercut projection) n1 attached to the circumferential surface of the bottom member 30, as shown in Figure 1(B). The lower cylindrical portion 3L in the illustrated example has a long cross-sectional shape in the front-rear direction, consisting of the main front wall portion 3a and the main rear wall portion 3c shown in Figure 1(A), and a pair of left and right main side wall portions 3b. A vertically elongated window hole H is opened in the main rear wall portion 3c. For the purposes of explanation, in this specification, the right side of Figure 1(A) will be referred to as "rear," the left side as "front," and the directions perpendicular to the plane of the paper will be referred to as left and right. The upper end of the window opening H is provided with a projection receiving portion 3d for receiving the locking projection 26 of the operating body 20, which will be described later. As shown in Figure 1(B), a locking rib 3f is erected on the inner surface of the lower part of the lower cylindrical portion 3L via an inward projection 3e to support the lower end of the inner sub-cylinder 6. The lower end of the inner sub-cylinder 6 is then clamped and fixed between the lower cylindrical portion 3L, the inward projection 3e, and the locking rib 3f. Furthermore, a grinding platform C is provided at the lower part of the lower cylindrical section 3L for grinding the contents between it and the movable teeth T of the movable body 12, which will be described later. In this specification, "grinding base" refers to a fixed part that is held between the moving teeth and the contents. Any shape or structure is acceptable as long as it can hold and grind the contents. In this embodiment, the grinding base C is formed as a protruding piece 4 projecting inward from the main front wall portion 3a, and a fixed tooth U facing the movable tooth T is provided on the tip (rear end) side of this protruding piece 4. In this specification, "movable teeth" refer to teeth that are attached to a fixed location on a movable body and are displaced when the movable body moves, while "fixed teeth" refer to teeth that are attached to a fixed location and are not displaced. Furthermore, both types of teeth may be collectively referred to as "crushing teeth." The protruding piece 4 in the illustrated example has an upper side portion 4a, an opposing side portion 4b, and a stiffening plate 4c, as shown in Figure 1(B). The opposing side portion 4b is the part that faces the front surface of the movable body 12, which will be described later, and multiple fixed teeth U are arranged in a stepped pattern on this opposing side portion 4b when viewed from the left and right directions. Furthermore, the upper part 4a is formed to gently slope downward and backward, serving as a guide slanted edge that directs contents such as sesame seeds to the grinding area between the grinding platform C and the movable body 12. The stiffening plate 4c is connected at both ends in the front-rear direction to the main front wall portion 3a and the protruding piece portion 4, respectively. The stiffening plate 4c has a vertical groove 4d for fitting the insertion projection L, which will be described later and rises from the bottom member 30. In this way, the main cylinder 3 and the bottom member 30 are connected. Furthermore, as shown in Figure 1(A), a contact projection 5 is provided at the lower end of the opposing side portion 4b to abut against the leading half of the wing member 50A, which will be described later. This contact projection 5 prevents the tip e of the blade member 50A from getting caught in the crushing area when the rotating body 12A, described later, returns from the second position P2 shown in Figure 1(B) to the first position P1 shown in Figure 1(C). The contact projection 5 in the illustrated example is positioned slightly in front of (immediately in front of) the tip e (the part depicted as bent in Figure 1(C)) of the blade plate 51 of the blade member 50A, leaving room for deformation of this tip e.

[0023] The inner sub-cylinder 6 is a member fitted inside the main cylinder 3, and in the illustrated example, it has a sub-front wall portion 6a and a sub-rear wall portion 6c as shown in Figure 1(A), and a pair of left and right sub-side wall portions 6b. Each of these wall portions abuts against the inner surface of the main cylinder 3. However, the upper half of the secondary rear wall portion 6c is formed into a forward bulge portion 6d by significantly bulging forward. The reason for providing the forward bulge portion 6d is to enable the operating body 20, which will be described later, to be pushed forward, and to house the biasing means B, which will be described later, inside the forward bulge portion 6d. In the illustrated example, the forward bulge 6d has a horizontal upper wall portion 6e, an inclined wall portion 6f that slopes downward and forward, and a vertical opposing wall portion 6g that faces the main front wall portion 3a, as shown in Figure 1(A). A communication passage a is formed between the main front wall portion 3a and the opposing wall portion 6g, which connects the inside of the container body 2 to the opening O. Furthermore, a coil spring is interposed between the opposing wall portion 6g and the operating body 20, which will be described later, as a biasing means B for biasing the operating body 20 backward. A support cylinder portion 6h for supporting the front end of this coil spring is provided projecting backward from the opposing wall portion 6g. In this embodiment, a pair of left and right support plates 6i are vertically mounted from a suitable location on the inner sub-cylinder 6 (in the illustrated example, the lower part of the forward bulge 6d) to support the rotating body 12A, which will be described later. Each support plate 6i has a shaft hole 6j for inserting the pivot shaft 18 of the rotating body 12A, and a shaft introduction groove 6k for guiding the pivot shaft 18 into the shaft hole 6j.

[0024] The operating member 10 is the part that performs the grinding action of the contents, and in this embodiment, it is composed of a rotating body 12A, which is a movable body 12, and an operating body 20 for rotating the rotating body 12A. In this embodiment, the rotating body 12A and the operating body 20 are molded as a single unit. However, this structure can be modified as appropriate.

[0025] The rotating body 12A has a plurality of movable teeth T arranged in a circumferential direction on the surface of an arc portion 16 centered on a rotation axis (a pivot axis 18 in the illustrated example), and this portion is responsible for crushing the contents by trapping them between these movable teeth T and the grinding base C. To achieve this action, the rotating body 12A is configured such that when it rotates from a first position P1 shown in Figure 1(A) to a second position P2 as shown in Figure 1(B) (hereinafter referred to as "forward rotation"), the movable tooth T descends near the sliding base C, and when it rotates again from that second position to the first position P1 as shown in Figure 1(C) (hereinafter referred to as "reverse rotation"), the movable tooth T rises near the sliding base C. In this specification, the first position P1 is the original position before performing the operation for the grinding work, and the second position P2 is the position (operating position) at the time when the operation (in this embodiment, the operation of tilting the operating body 20 forward) has been completed. In this embodiment, the rotating body 12A is composed of a rear plate portion 13, a pair of left and right side plate portions 14, an upper plate portion 15, and an arc portion 16, as shown in Figure 1(A). The rear plate portion 13 is a vertically elongated, strip-shaped plate portion positioned within the window opening H, and the pair of left and right side plate portions 14 protrude forward from both sides of the rear plate portion 13, parallel to each other. From each of the pair of side plate portions 14, a pivot portion 18 protrudes outward in the left-right direction. The edges of these side plate sections 14 are connected to both ends of the upper plate section 15 and the arc section 16, respectively. The upper plate section 15 extends forward from the upper end of the rear plate section 13, and the arc section 16 extends downward and forward from the front end of the upper plate section 15. Furthermore, the term "arc portion" refers to any part that has an arc-shaped outer surface when viewed from the axial direction. In this embodiment, as shown in Figure 1(A), the surface of the arc portion 16 is arranged from top to bottom, with a restricting projection 17, a plurality of crushing projections S, and a plurality of movable teeth T. The restricting projection 17 serves to restrict the rotation range of the rotating body 12A. Specifically, after the multiple moving teeth T pass near the grinding base C (grinding area) due to the forward rotation of the rotating body 12A, the rotation is stopped when the restricting projection 17 contacts a suitable location on the container body 1 (upper edge 4a in the illustrated example), as shown in Figure 1(B). This eliminates the inconvenience of unnecessary rotation of the rotating body 12A. The crushing protrusions S serve to crush the contents to a certain degree of fineness. By using the crushing process by the crushing protrusions S in combination with the grinding process between the moving teeth T and the fixed teeth U, the contents can be ground more finely. The crushing protrusions S can be dot-shaped protrusions arranged in a scattered pattern when viewed from the radially outer side of the rotating body 12A. This configuration allows for the effective crushing of contents (such as sesame seeds) accumulated near the fixed teeth U. The movable tooth T is a cutting edge oriented in the width direction (left-right direction) of the arc portion 16. The cross-sectional shape of the movable tooth T in the illustrated example is an obtuse isosceles triangle, and the tooth surface oriented in the forward direction, represented by the symbol t1 in Figure 1(B), and the tooth surface oriented in the reverse direction, represented by the symbol t2 in Figure 1(C), have substantially the same slope in their respective directions. As a result, when the rotating body 12A is rotated in the forward direction and when it is rotated in the reverse direction, the tip e of the vane member 50A, described later, comes into contact with the two tooth surfaces t1 and t2 of the movable tooth T, respectively, and a scraping action of adhering material is obtained.

[0026] The operating body 20 has a main operating section 22 for grinding the contents. In this embodiment, the main operating section 22 is an inner pressing plate section 22A, which in the illustrated example extends upward from the rear plate section 13 within the window opening H. The biasing means B described above is interposed between the inner pressing plate portion 22A and the opposing wall portion 6g of the inner sub-cylinder 6. Furthermore, as shown in Figure 1(A), a locking projection 26 is provided at the upper end of the operating body 20, projecting from the upper end of the inner pressing plate portion 22A via a horizontally oriented U-shaped connecting plate 24. By engaging this locking projection 26 with the projection receiving portion 3d at the upper end of the window hole H, it counteracts the rearward biasing force of the biasing means B. However, these structures can be modified as appropriate, and instead of a U-shaped connecting plate, a locking projection 26 may be provided at the upper end of a vertical connecting plate. When the inner pressing plate portion 22A is pressed inward, the biasing means B is elastically compressed, causing the inner pressing plate portion 22A and the rear plate portion 13 to tilt forward. As a result, the rotating body 12A rotates from the first position P1 to the second position P2, as shown in Figure 1(B). When the pressing is released, the elastic restoration of the biasing means B causes the inner pressing plate portion 22A and the rear plate portion 13 to return to an upright position, and the rotating body 12A returns from the second position P2 to the first position P1. The operating body 20 is provided with a push-down button 25 below the locking projection 26. When this push-down button 25 is pressed, the connecting plate 24 bends (not shown in the diagram), releasing the engagement between the locking projection 26 and the projection receiving portion 3d. The biasing force of the biasing means B causes the inner pressing plate portion 22A and the rear plate portion 13 to tilt backward. As a result, although not shown in the diagram, the arc portion 16 moves significantly away from the grinding stand C. In this state, the contents can be discharged to the outside from the discharge port 42 (described later) without being ground at all.

[0027] The bottom member 30 is attached to the lower end of the main cylinder 3 and has a removal body 50 for scraping off crushed deposits from the movable teeth T. This removal body 50 is located below the gap between the sliding base C and the moving teeth T, and is configured to come into contact with the moving teeth T and scrape off any attached material as the operating body 20 is operated. However, this structure can be modified as appropriate, and the attachment 50 may be provided on a member other than the bottom member 30.

[0028] In this embodiment, the bottom member 30 has a fitting portion 32 that fits onto the inner surface of the lower end of the main cylinder 3, and a bottom plate portion 41 is attached to this fitting portion 32 in connection with it. An outlet 42 is opened in this bottom plate portion 41, positioned below the opening O. A support portion 34 is provided in a suitable location on the fitting portion 32 (the front portion in the illustrated example) below the sliding base C to support the attachment body 50. In this embodiment, the attachment body 50 is a wing member 50A that protrudes rearward from the support portion 34. The wing member 50A in this embodiment has a plurality of wing plates 51 provided in the upper, lower, left, and right directions. The tips e of the plurality of wing plates 51 are formed as sharp corners when viewed from the left and right directions. These corners are formed so as to be inserted into the gaps between the moving teeth T of the arc portion 16, as shown in Figure 1(B). Therefore, deposits between the moving teeth T can be efficiently scraped off.

[0029] Furthermore, the support portion 34 in this embodiment is a support base portion 34A that supports the base side of the wing member 50A, as shown in Figure 1(B). This support base portion 34A is formed of a base plate portion 35 connected to the fitting portion 32, a hanging plate portion 36 hanging down from the rear end of the base plate portion 35, and a stiffening portion 37 connected to the base plate portion 35 to connect the fitting portion 32 and the hanging plate portion 36. The wing member 50A is integrally provided to protrude rearward from the upper part of the hanging plate portion 36. However, these structures can be modified as appropriate.

[0030] In the above configuration, in the state shown in Figure 1(A), the contents inside the container body 1 reach the gap between the grinding surface C and the rotating body 12A via the connecting passage a. When the inner pressing plate portion 22A is pressed forward from the state shown in Figure 1(A), the locking projection 26 of the operating body 20 separates from the projection receiving portion 3d of the main cylinder body 3, and the rotating body 12A rotates around the pivot shaft 18 from the first position P1 to the second position P2 shown in Figure 1(B). As the rotating body 12A rotates, the multiple movable teeth T pass near the grinding base C, and the contents are ground between the fixed teeth U of the grinding base C and the movable teeth T. Most of the ground contents fall downward through the opening O and are supplied to the outside through the discharge port 42. In parallel with this grinding process, the tip e of the blade member 50A comes into contact with one tooth surface t1 of each moving tooth T that has come out downward from the grinding area (the gap between the grinding stand C and the rotating body 12A). Because the blade plate 51 of the blade member 50A is flexible, the blade plate 51, which has bent after overcoming one moving tooth T, strikes against one tooth surface t1 of the next moving tooth T. This impact effectively scrapes off any deposits on the tooth surface t1. Since the blade member 50A is made up of multiple overlapping blade plates 51, the number of times these blade plates 51 strike a single tooth surface is repeated, improving the scraping function. Next, as the multiple crushing protrusions S approach the grinding surface C, the contents accumulated near the fixed teeth U are crushed by these crushing protrusions S. When the rotating body 12A reaches the second position P2, the regulating projection 17 strikes the upper edge 4a of the scraping table C, causing the rotating body 12A to stop. This completes the process of grinding the contents and scraping off any attached material in forward rotation. Next, when the indentation of the inner pressing plate portion 22A is released, the elastic restoring force of the biasing means B causes the rotating body 12A to rotate in the reverse direction toward the first position P1. At this time, the tip e of the blade member 50A comes into contact with the other tooth surface t2 of each movable tooth T, and any remaining deposits on the tooth surface of the movable tooth T are scraped off. In this process, the contact projection 5 of the sliding base C is in contact with the leading half of the blade plate 51, so the blade plate 51 bends slightly, preventing its tip e from getting caught between the fixed tooth U and the movable tooth T. Then, when the rotating body 12A returns to the first position P1, the locking projection 26 of the operating body 20 is held by the projection receiving portion 3d, and the position of the operating member 10 is maintained.

[0031] According to the above configuration and operation, a removal body 50 is provided for scraping off the ground-down deposits that come into contact with the movable teeth T when the operating body 20 is operated. Therefore, by operating the operating body 20, the contents can be ground up and the deposits attached to the movable teeth T can be scraped off. Since the tip e of the blade member 50A sequentially strikes a series of moving teeth T, it is possible to accurately scrape off any material adhering to each individual moving tooth T. Moreover, because the scraping operation is performed in both the forward and reverse rotation of the rotating body 12A, the scraping function is improved.

[0032] Other embodiments of the present invention will be described below. In these descriptions, the same structures as those in the first embodiment will not be explained.

[0033] Figure 2 shows a mill container according to a second embodiment of the present invention. In this embodiment, the mounting body 50 uses a rotating brush 50B instead of the blade member 50A of the first embodiment, and instead of the support base portion 34A of the first embodiment, a pair of left and right support wall portions 34B that support the rotating brush are provided as shown in Figure 2(B). As shown in Figure 2(B), the rotating brush 50B has brush bristles arranged around a shaft i oriented in the left-right direction, and both ends of the shaft i are rotatably supported by concave bearings j (bearing recesses) formed at the upper ends of a pair of left and right support walls 34B provided on the bottom member 30. In this embodiment, the bottom plate portion 41 of the bottom member 30 is disc-shaped, with its peripheral edge 43 protruding from the contour of the main cylindrical body 3 when viewed from above, and parallel support wall portions 34B are erected from this bottom plate portion 41. The bearings j of these support wall portions 34B are positioned so as to rub against multiple movable teeth T from the outside of the arc portion 16. When the rotating body 12A rotates in the forward or reverse direction, the rotating brush 50B rotates around the bearing j due to the frictional force with the rotating body 12A. With this structure, the frictional action of the rotating brush 50B from the outside allows for even and efficient scraping of attached material onto the multiple movable teeth T arranged in parallel on the arc portion 16 of the rotating body 12A. In this embodiment, the contact projection 5 provided at the lower end of the opposing side portion 4b of the scraping base C in the first embodiment is omitted. Instead, as shown in Figure 2(A), an upwardly convex recess y is formed corresponding to the contour of the rotating brush 50B when viewed from the left and right directions. This prevents the scraping base C from contacting the rotating brush 50B and hindering its rotation.

[0034] Figure 3 shows a mill container according to a third embodiment of the present invention. In this embodiment, instead of the rotating brush 50B that rubs the moving teeth T from the outside of the arc portion 16 as disclosed in the second embodiment, a rotating brush 50B that rubs the moving teeth T from the inside of the arc portion 16 is used, as shown in Figure 3(B). Specifically, the arc portion 16 is provided with through-holes x that penetrate radially, positioned between the movable teeth T. The movable teeth T are then rubbed by a rotating brush 50B, which is rotatably supported inside the arc portion 16, through these through-holes x. With this configuration, since the multiple movable teeth T are rubbed from the inside of the arc portion 16 through the insertion hole x, the tooth surface can be rubbed from the root side of the movable teeth T, which is difficult to reach from the outside, allowing for more reliable and effective scraping of attached material.

[0035] In this embodiment, the rotating brush 50B is supported by the inner sub-cylinder 6. The bottom member, which was a support means for the rotating brush in the second embodiment, is omitted. In this embodiment, as shown in Figure 3(A), bearings j are formed on the front of the left and right pair of pivot plates 6i of the inner sub-cylinder 6 described above. The ends of the shaft i of the rotating brush 50B are pivotally supported by these bearings j. In the illustrated example, as shown by the dotted line in Figure 3(B), the upper end of the slit J extending upward from the lower edge of the shaft support plate 6i is used as the bearing j, and a constricted portion is provided on the lower side of the upper end of the slit J, so that both ends of the shaft i can pass over this constricted portion and be held within the bearing j. In the illustrated example, arc-shaped holes q are opened in the left and right side plates 14 of the rotating body 12A, along and concentrically with the arc-shaped portion 16, and both ends of the shaft i of the rotating brush 50B are supported by the bearing j through these arc-shaped holes q. Furthermore, the main cylinder 3, as seen from the left and right directions, has the inward projection 3e and the locking rib 3f cut through, forming a shaft introduction groove 3g from the upper end of the locking rib 3f to the vicinity of the shaft i, for guiding both ends of the shaft.

[0036] Figure 4 shows a mill container according to a fourth embodiment of the present invention. First, to briefly explain the differences from the configuration of the first embodiment, this embodiment uses a lifting body 12B instead of the rotating body 12A of the first embodiment as the movable body 12, a lower sub-cylinder 7 attached to the lower end of the main cylinder 3 instead of the inner sub-cylinder 6 of the first embodiment, and a diaphragm ring 50C instead of the blade member 50A.

[0037] In this embodiment, the container body 1 consists of a main cylinder body 3 and a lower sub-cylinder body 7 fitted to the lower end of the main cylinder body 3. In the illustrated example, both the main cylinder body 3 and the lower sub-cylinder body 7 are straight cylinders and are formed to the same diameter.

[0038] A guide tube portion 3j is erected on the inner surface of the upper half of the main cylinder 3 via an inward-facing flange 3i to guide the connecting rod 27, which will be described later. A locking step portion d is formed at the corner between the inward-facing flange 3i and the guide tube portion 3j for mounting a coil spring, which is a biasing means B. Furthermore, positioned above the inward-facing flange 3i, the main cylinder 3 has a pair of guide grooves G for guiding the sliding projection 23 of the pressing cylinder portion 22B, which will be described later. As shown in Figure 4(A), the guide grooves G are formed by vertically oriented grooves g2 extending downward from the end of a horizontal groove g1. Although not shown, projection introduction grooves may also be formed at appropriate locations on the inner surface of the main cylinder 3 to guide the sliding projection 23 from the outside into the guide grooves G. The lower end of the main cylinder 3 is formed as a small outer diameter portion 3k. Around this small outer diameter portion 3k, a male thread portion w2 is formed for engagement with the female thread portion w1 of the lower sub-cylinder 7. The interior of the main cylinder 3 serves as a storage compartment A for the contents.

[0039] As shown in Figure 4(1), the lower sub-cylinder 7 consists of a leg cylinder 8 and a support cylinder 9 connected to the leg cylinder 8. An annular groove 8a is formed at the upper end of the leg cylinder 8 for fitting the small outer diameter portion 3k. A female thread portion w1 is formed on the inner surface of this annular groove. The support cylinder 9 is the part that grinds the contents between itself and the outer surface of the lifting body 12B, and serves as the grinding surface C mentioned above. However, unlike the grinding surface of the first embodiment, the support cylinder 9 does not have fixed teeth U. The support cylinder 9 in the illustrated example consists of an upright cylinder portion 9a that stands integrally from the leg cylinder 8 inside the annular groove portion 8a, a tapered cylinder portion 9b that protrudes downward and inward from the upper end of the upright cylinder portion 9a, and a hanging cylinder portion 9c that hangs down from the lower end of the tapered cylinder portion 9b.

[0040] The tapered cylindrical portion 9b is fitted with a diaphragm ring 50C, which is a mounting body 50. This diaphragm ring 50C is elastic and is attached to the lower inner surface end of the hanging cylinder portion 9c via a thin-walled ring pivot point 52. In the initial state shown in Figure 4(B), the throttling ring is formed in the shape of a ring plate with its inner end slightly lower, and is designed so that by lowering the lifting body 12B as shown in Figure 4(C), it is possible to scrape off any deposits from the moving teeth T on the circumferential surface of the lifting body 12B.

[0041] In this embodiment, the operating body 20 has a pressing cylinder portion 22B which is the main operating part 22, and a connecting rod 27 is suspended from a connecting plate portion 28 that is horizontally attached to the pressing cylinder portion 22B. The lower half of the pressing cylinder portion 22B is inserted into the upper part of the main cylinder 3. A biasing means B is interposed between the connecting plate portion 28 and the inward-facing flange 3i. A pair of sliding protrusions 23 attached to the lower end of the pressing cylinder portion 22B are inserted into the guide groove G. With this structure, by rotating the pressing cylinder portion 22B to move the sliding protrusions 23 from the horizontal groove portion g1 to the upper end of the vertical groove portion g2, the operating body 20 can be lowered against the elastic force of the biasing means B by pushing down the pressing cylinder portion 22B.

[0042] In this embodiment, the movable body 12, which is the lifting body 12B, is linearly attached to the lower part of the connecting rod 27. In the illustrated example, a fitting hole 12d is formed on the upper surface of the upper end portion 12c of the lifting body 12B, and the lower end portion of the connecting rod 27 is fitted into this fitting hole. The lower end portion 12e of the lifting body 12B is located inside the hanging cylindrical portion 9c in the initial state shown in Figure 4(A). Multiple circumferential moving teeth T are arranged in parallel in the vertical intermediate portion of the lifting body 12B. In the illustrated example, the outer circumferential surface of the intermediate portion is divided into multiple circumferential grooves 12f, and multiple circumferential moving teeth T are formed in each section.

[0043] In the above configuration, when the pressing cylinder portion 22B is rotated and pressed down so that the sliding projection 23 and the vertical groove portion g2 are aligned, the lifting body 12B descends together with the operating body 20, the lower end portion 12e of the lifting body 12B contacts the aperture ring 50C, and the aperture ring 50C expands around the ring pivot point 52. As the operating body 20 and the lifting body 12B are further lowered, as shown in Figure 4(C), the moving teeth T of the lifting body 12B enter the hanging cylinder section 9c, and the contents are crushed between the moving teeth T and the hanging cylinder section 9c. Most of the crushed material falls to the outside. As the lifting body 12B is lowered further, the inner end of the throttling ring 50C rubs against the multiple moving teeth T that are arranged in parallel in the vertical direction, scraping off any deposits that have accumulated between the moving teeth T. In this way, the throttling ring 50C is pressed against the circumferential surface of the lifting body 12B, allowing for even and efficient removal of adhering material from the entire circumferential surface.
