Description

Technical Field

[0001] The present invention relates to a container for containing a solid product, and in particular to a grinding container capable of crushing the solid product to provide a grinding product. Background Art

[0002] Some functional composition products are manufactured and distributed as solids in a predetermined volume. When the composition is provided in solid form, there is an advantage that there is no problem of spilling or leaking from the container like a liquid product, but on the other hand it may be more difficult to apply to the desired area compared to a liquid product. Recently, a grinding container has been developed in which, in order to make it easier to use the solid product, the container itself is provided with a cutting edge to discharge the crushed powder after the solid product is crushed.

[0003] In the grinding container, some components are fixed and some components are rotating, so that relative movement frequently occurs between the components. In addition, some components are required to press the solid product toward the mountain based on the user's operation. In this structure, the product can only be used normally if the components are completely aligned in the correct position. However, if the part of the component supporting the movement is made too rigid, there is a concern that the corresponding part may be worn and damaged due to stress concentration, and if the part of the component supporting the movement is too soft, there is a concern that the crushing action cannot be performed correctly because the supported content cannot be maintained in the correct alignment state. Summary of the invention

[0004] Technical issues

[0005] Therefore, the present invention is proposed to solve the above-mentioned problems. One aspect of the present invention is to provide a grinding container in which the content can be kept stably aligned while the portion supporting the moving components has an appropriate degree of flexibility.

[0006] Another aspect of the present invention is to provide a grinding container that can be conveniently used by a user.

[0007] Other objects of the present invention will become more apparent from the embodiments described below.

[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. When describing with reference to the accompanying drawings, the same or corresponding components will be given the same reference numerals regardless of the reference numerals, and repeated descriptions thereof will be omitted.

[0036] For the sake of convenience, in this specification, the expressions "inside", "outside", "upper side", "lower side" and the like are used. In the following description, "inside" refers to the side close to the inside of the grinding container 1000, and "outside" refers to the side away from the inside of the grinding container 1000. On the other hand, "upper side" and "lower side" refer to the sides of the grinding container 1000 such as the sides of the grinding container 1000. Figures 1 to 3 The configuration shown is used as a reference, and "longitudinal" refers to the vertical up-down direction. Of course, when the grinding container 1000 of an embodiment of the present invention is actually used, the upward direction described in the specification may not be consistent with the actual upward direction.

[0037] Figures 1 to 3 as well as Fig.11The grinding container 1000 according to one embodiment of the present invention is exemplarily shown. As shown in the figure, the grinding container 1000 according to one embodiment of the present invention may include a rotary disk 100, a container body 200, a plunger 300, a cutting plate 400, and a top cover 500. Figure 4 and Figure 5 Describing the turntable 100 in more detail, Figure 6 and Figure 7 The container body 200 is depicted in greater detail. Figures 8 to 10 Plunger 300 is depicted in greater detail. Fig.12 and Fig.13 Describing the cutting plate 400 in more detail, Fig.14 Top cover 500 is depicted in greater detail.

[0038] The turntable 100 corresponds to a portion that a user holds and operates in order to utilize the grinding container 1000, and for this purpose, is rotatably coupled to the lower portion of the container body 200. Figures 1 to 5 The turntable 100 may include a disk 110 , a side wall 120 , a coupling edge 130 , a reinforcing rib 140 , a first insertion coupling portion, a reinforcing wall 170 , and a guide post 180 .

[0039] The disk 110 may form the lower side of the turntable 100 and function as a base for other components of the turntable 100. In a preferred embodiment, the disk 110 may be formed to have a size and shape capable of shielding the lower portion of the sleeve 250 of the container body 200. Although the disk 110 depicted as the turntable 100 in the figure has a circular shape and the turntable 100 is a portion rotated by a user, the disk 110 does not necessarily have to have a circular shape.

[0040] A plurality of margin slits 115 may be formed on the disk 110. Each margin slit 115 may have at least a portion formed in an arc shape and may be formed inside the coupling edge 130. In a preferred embodiment of the present invention, the margin slit 115 may be formed adjacent to each of the plurality of coupling edges 130.

[0041] The side wall 120 may extend upward from the edge of the disk 110. The length of the side wall 120 extending upward may be determined so that the upper end of the side wall 120 contacts or is adjacent to the main shell 210 of the container body 200 when the turntable 100 is coupled to the container body 200. The position and size of the side wall 120 may be determined so that its outer surface is continuous with the outer surface of the main shell 210. The side wall 120 may be formed along the entire edge of the disk 110 and formed to shield the inner side thereof.

[0042] The coupling edge 130 may extend upward from the disk 110 from a position corresponding to the sleeve cylinder 250, and a coupling protrusion 136 may be formed on the upper portion of the coupling edge 130. The rotary disk 100 may include a plurality of coupling edges 130, and each coupling edge 130 may have a cross section in an arc shape centered at the center of the disk 110. Figure 3 As shown, the coupling edge 130 may have an inclination that inclines toward the inner side as it goes upward.

[0043] In addition, the length of the upper portion of the coupling edge 130 is shorter than the length of the lower portion, so that when the shape of the coupling edge 130 is projected diagonally upward, it can be a trapezoidal shape. The coupling protrusion 136 is formed on the upper portion of the coupling edge 130, and is preferably configured so that it is not formed on the entire upper portion of the coupling edge 130, so that parts without the coupling protrusion 136 are left on both sides of the upper portion of the coupling edge 130.

[0044] As previously described, the margin slit 115 may be formed adjacent to each of the bonding edges 130. Figure 4 As shown, the coupling edge 130 and the margin slit 115 may both be formed in an arc shape centered at the center of the disk 110 , and the margin slit 115 may be formed inside the coupling edge 130 with a length corresponding to that of the coupling edge 130 .

[0045] The reinforcing rib 140 may connect adjacent joining edges 130 at the lower portion of the joining edge 130. That is, the reinforcing rib 140 may extend upward from the disk 110, and both side ends may be respectively connected to the lower portion of the joining edge 130. The reinforcing rib 140 may also have a cross section of an arc shape centered at the center of the disk 110.

[0046] exist Figure 3 In the example shown, the inner surface of the reinforcing rib 140 has a smaller curvature radius than the inner surface of the coupling edge 130, and the outer surface of the reinforcing rib 140 has a curvature radius greater than the inner surface of the coupling edge 130 and smaller than the outer surface of the coupling edge 130. Both side ends of the reinforcing rib 140 may be formed to overlap with the corresponding ends of the coupling edge 130. As described above, the coupling protrusions 136 may not be formed on both sides of the upper portion of the coupling edge 130, and preferably, the coupling protrusions 136 may not be formed at the portion where the reinforcing rib 140 is formed.

[0047] The rotary disk 100 may include a first insertion joint, which may extend upward from the circular disk 110. The first insertion joint is configured to engage with a second insertion joint formed in the plunger 300, and one of the first insertion joint and the second insertion joint may include a sleeve, and the other may include a support column. In the example shown in the figure, the first insertion joint formed in the rotary disk 100 may be implemented in a form including a sleeve 160, and the second insertion joint formed in the plunger 300 may be implemented in a form including a support column 360.

[0048] The sleeve 160 extends upward from the disc 110 and is hollow, so that an insertion space 165 can be formed inside it. Therefore, the insertion space 165 can be open to the upper part and can accommodate the support column 360 inserted downward from the upper part. The sleeve 160 can be formed in a shape such that the insertion space 165 does not have a circular cross-section. In the example shown in the figure, the sleeve 160 is formed in the shape of a hollow hexagonal column.

[0049] The guide pillars 180 can be more firmly fixed by connecting the plurality of guide pillars 180 to each other at the lower part of the guide pillars 180 through the reinforcing wall 170. The reinforcing wall 170 can extend upward from the disk 110 in an annular shape and can be respectively connected to the lower part of the outer end of the guide pillars 180. A connecting portion 172 connected to the first insertion joint (e.g., sleeve 160) can also be formed on the reinforcing wall 170, thereby also making the first insertion joint (e.g., sleeve 160) firmly fixed.

[0050] The guide post 180 may extend upward from a position other than the center of the disk 110. In a preferred embodiment of the present invention, the turntable 100 may include a plurality of guide posts 180, and the side surfaces of the guide posts 180 may have a flat shape. Fig.11 As shown in the illustrated example, the guide post 180 may extend along a virtual straight line whose cross section passes through the center of the disk 110. That is, the inner side of each guide post 180 is configured to face the rotation center of the turntable 100, so that the wider side of the guide post 180 may face the direction of the impedance rotation. This shape of the guide post 180 may help prevent the plunger 300 from rotating relative to the turntable 100.

[0051] When the first insertion joint includes the sleeve 160, a portion of each guide post 180 may be located inside the sleeve 160, and the remaining portion may be located outside the sleeve 160. That is, in a preferred embodiment of the present invention, the guide post 180 may be as follows: Figure 4 The structure shown is realized in a shape that intersects with the sleeve 160. This structure enables a very strong and stable combination between the first insertion joint (ie, the sleeve 160) and the second insertion joint (ie, the support column 360).

[0052] Reference Figure 3 , the guide pin 180 can pass through the guide slit 380 formed in the retaining plate 310 of the plunger 300. The solid content (not shown) is arranged on the retaining plate 310 of the plunger 300, and the guide pin 180 extends through the retaining plate 310, so a guide slit of the same size and shape as the guide slit 380 can also be formed in the solid content (not shown) arranged on the retaining plate 310.

[0053] The container body 200 corresponds to the main part of the grinding container 1000, and can form a main body combined with other components, and can accommodate contents (not shown) inside. Figure 6 and Figure 7 The container body 200 may include a main shell 210 , an outer coupling edge 220 , an inner coupling edge 230 , a support portion 240 , and a sleeve cylinder 250 .

[0054] The main shell 210 may form a main part of the container body 200 and may have a cylindrical shape as a whole. The main shell 210 may form an installation space 215 inside thereof, and the plunger 300 and the solid content (not shown) disposed thereon may be accommodated in the installation space 215. As shown in the example shown in the figure, the main shell 210 may form a part of the appearance of the grinding container 1000.

[0055] In one embodiment of the present invention, a lug 212 may be formed on the upper portion of the main shell 210. In the portion where the lug 212 is formed, as the outer diameter of the main shell 210 increases, a boss may be formed on the upper portion thereof. Such a shape of the lug 212 may ensure space for the outer coupling edge 220 and the inner coupling edge 230 on the upper portion of the lug 212.

[0056] The outer bonding edge 220 and the inner bonding edge 230 may extend upward from the upper side of the lug 212 of the main shell 210, and the outer bonding edge 220 may have a larger diameter than the inner bonding edge 230, thereby forming a gap between the outer bonding edge 220 and the inner bonding edge 230. The outer bonding edge 220 and the inner bonding edge 230 may be used to bond the cutting board 400 to the container body 200 and stably support it. For example, the inner bonding edge 440 of the cutting board 400 may be inserted into the gap between the outer bonding edge 220 and the inner bonding edge 230.

[0057] A coupling protrusion and / or a fixing protrusion may be formed on at least one of the outer coupling edge 220 and the inner coupling edge 230. For example, in the example shown in the figure, a coupling protrusion 222 is formed on the outer peripheral surface of the outer coupling edge 220. The coupling protrusion 222 may extend over most of the outer peripheral surface of the outer coupling edge 220 and form an annular shape as a whole. When the cutting plate 400 is coupled to the container body 200, the coupling protrusion 222 may be inserted into the coupling groove formed on the outer coupling edge 430 of the cutting plate 400 to prevent the cutting plate 400 from being separated from the container body 200 in the longitudinal direction.

[0058] In the example shown in the figure, a fixing protrusion 224 is also formed on the outer peripheral surface of the outer side joint edge 220. The fixing protrusion 224 may protrude outward at one or more designated positions on the outer peripheral surface of the outer side joint edge 220. When the cutting plate 400 is coupled to the container body 200, the fixing protrusion 224 may be inserted into the fixing groove 434 formed on the outer side joint edge 430 of the cutting plate 400, thereby preventing the cutting plate 400 from rotating relative to the container body 200.

[0059] The support portion 240 may be formed at the lower portion of the main housing 210 and connect the main housing 210 and the sleeve cylinder 250 on one hand, and may function as the turntable 100 coupled to the container body 200 on the other hand. The support portion 240 may have a reduced diameter at the lower portion of the main housing 210, so that a boss 244 facing downward may be formed at the lower end of the main housing 210, and the support portion 240 itself may also form a boss from the lower portion thereof. In order to allow the side wall 120 of the turntable 100 to be easily mounted on the support portion 240, an inclined surface may be formed on the outer side of the lower portion of the support portion 240.

[0060] The sleeve cylinder 250 may be connected to the support portion 240 and formed at a designated position of the inner lower portion of the main housing 210. The sleeve cylinder 250 may extend a predetermined length in the longitudinal direction and may form an operation channel 255 inside thereof. The sleeve cylinder 250 may have a cylindrical shape with upper and lower portions open, so that the operation channel 255 leads upward to the installation space 215 and downward to the outside. That is, the sleeve cylinder 250 may communicate the installation space 215 with the outside through the operation channel 255.

[0061] The operation channel 255 of the sleeve cylinder 250 provides a channel for the rotary disk 100 disposed outside the container body 200 and the plunger 300 disposed inside the container body 200 to interact with each other. In one embodiment of the present invention, the sleeve cylinder 250 itself can participate in the operation of the rotary disk 100 and the plunger 300. For example, a thread can be provided on one of the inner circumference of the sleeve cylinder 250 and the outer circumference of the rod 350 of the plunger 300, and an engaging protrusion engaged with the thread can be provided on the other. In a preferred embodiment, the diameter of the sleeve cylinder 250 can be designed to be more than 1 / 2 of the diameter of the retaining plate 310 of the plunger 300.

[0062] exist Figure 6 In the example shown, the engagement protrusion 252 is formed on the inner circumferential surface of the sleeve cylinder 250. The engagement protrusion 252 may be formed at a position close to the upper end of the sleeve cylinder 250, and may have a shape corresponding to a thread in a manner that can be engaged with a thread 352 formed on the rod 350 of the plunger 300. Of course, the engagement protrusion 252 may also be implemented in the form of a thread. That is, in one embodiment of the present invention, the engagement protrusion 252 may also be implemented in the form of a thread (i.e., an internal thread) formed on the entire inner circumferential surface of the sleeve cylinder 250.

[0063] Reference Figure 7 , an alignment protrusion 254 may be formed on the outer circumferential surface of the sleeve cylinder 250, and the alignment protrusion 254 may be formed at the lower portion of the sleeve cylinder 250. The alignment protrusion 254 may protrude outward in an annular shape on the entire outer circumferential surface of the sleeve cylinder 250, and its lower portion may be in a gently inclined or curved shape. When the turntable 100 is combined with the container body 200, the outer side of the alignment protrusion 254 contacts the reinforcing rib 140 of the turntable 100, thereby helping to maintain the alignment state relative to the container body 200 even during the rotation of the turntable 100. The inclination or curvature of the lower portion of the alignment protrusion 254 enables the alignment protrusion 254 to be more easily inserted into the inner side of the reinforcing rib 140.

[0064] A coupling protrusion 256 may also be formed on the outer circumference of the sleeve cylinder 250. The coupling protrusion 256 may protrude outward in an annular shape on the entire outer circumference of the sleeve cylinder 250, and, Figure 7 As shown, it can be formed at a higher position than the alignment protrusion 254. The lower part of the coupling protrusion 256 can also have an inclination or curvature. When the turntable 100 is coupled to the container body 200, the coupling protrusion 256 can be engaged with the coupling protrusion 136 formed on the coupling edge 130 of the turntable 100. The coupling protrusions 136 and 256 of the coupling edge 130 and the sleeve cylinder 250 can allow the turntable 100 to rotate relative to the container body 200 and prevent the turntable 100 from being separated from the container body 200 in the longitudinal direction.

[0065] The plunger 300 is a portion that supports the contents (not shown) and is also a portion that moves in the longitudinal direction based on the operation of the user. Figures 8 to 10 , the plunger 300 may include a holding plate 310, a connecting portion 320, a close-fitting portion 330, a rod 350, and a second insertion coupling portion.

[0066] The holding plate 310 is a portion on which solid contents (not shown) are supported, and may have a circular flat plate shape as a whole. The contents (not shown) may include a composition for products such as cleaning balm and deodorant, and may be supplied to the holding plate 310 in a solid form. In order to prevent the contents (not shown) from being easily separated, a concave portion that is concave downward and / or a convex portion that is convex upward may be formed in the holding plate 310.

[0067] A guide slit 380 may be formed on the holding plate 310, and a similar guide slit may also be formed in the content (not shown) provided to the holding plate 310. The guide post 180 of the turntable 100 may extend upward through the guide slit 380 and may pass through a portion of the content (not shown) disposed on the holding plate 310.

[0068] On the bottom surface of the retaining plate 310, an alignment groove 315 may be formed around the rod 350. The alignment groove 315 may be formed at a position corresponding to the upper end of the sleeve cylinder 250 of the container body 200, and when the plunger 300 is at the lowest position in the installation space 215, the upper end of the sleeve cylinder 250 may be inserted into the alignment groove 315.

[0069] like Figure 3 As shown, the connection portion 320 may extend downward from the edge of the holding plate 310. The connection portion 320 is a portion that connects the abutting portion 330 to the holding plate 310, and may support the abutting portion 330 at a middle height of the abutting portion 330 based on the longitudinal direction, and enable the upper end of the abutting portion 330 to be located close to the upper side of the holding plate 310.

[0070] The close-fitting portion 330 may be located at the edge of the plunger 300 and may be connected to the lower portion of the connecting portion 320 through the connecting flange 322. The close-fitting portion 330 may extend up and down and may be formed to have a thickness that can have some flexibility, and, based on the middle height of the close-fitting portion 330, the upper portion of the close-fitting portion 330 may have an increasing outer diameter as it goes upward, and the lower portion of the close-fitting portion 330 may have an increasing outer diameter as it goes downward. Thus, the close-fitting portion 330 may be closely attached to the inner circumference of the main housing 210 in a relatively watertight manner to minimize leakage of the contents (not shown) to the bottom of the plunger 300.

[0071] The rod 350 may extend downward from the bottom surface of the retaining plate 310. In one embodiment of the present invention, the diameter of the rod 350 may be designed to be greater than 1 / 2 of the diameter of the retaining plate 310. As described above, in one embodiment of the present invention, a thread may be provided on one of the inner circumferential surface of the sleeve cylinder 250 and the outer circumferential surface of the rod 350, and an engaging protrusion engaged with the thread may be provided on the other. In the example shown in the figure, the thread 352 is formed on the outer circumferential surface of the rod 350 of the plunger 300. In a state where the plunger 300 is combined with the container body 200, the engaging protrusion 252 of the sleeve cylinder 250 may be engaged with the thread 352 of the rod 350. In some embodiments of the present invention, an engaging protrusion may be formed in the rod 350, and a thread may be formed in the sleeve cylinder 250.

[0072] According to the figure, the rod 350 of the plunger 300 is inserted into the inner side of the sleeve cylinder 250 and a thread 352 is formed on the outer circumference of the rod 350, and an engaging protrusion 252 is formed on the inner circumference of the sleeve cylinder 250. However, in some embodiments of the present invention, the sleeve cylinder 250 may be inserted into the inner side of the rod 350 and threads and engaging protrusions may be formed on the outer circumference of the sleeve cylinder 250 and the inner circumference of the rod 350. Of course, in this case, the length of the rod 350 extending downward may be limited by the position of the support portion 240.

[0073] The second insertion joint portion may extend downward from the bottom surface of the retaining plate 310 and engage with the first insertion joint portion of the rotary disk 100 through the operation channel 255 formed in the container body 200. In the example shown in the figure, the first insertion joint portion formed on the rotary disk 100 is implemented in a form including the sleeve 160, and the second insertion joint portion formed on the plunger 300 is implemented in a form including the support column 360.

[0074] The sleeve 160 and the support column 360 may have a non-circular cross section, and the support column 360 may be configured to be inserted into the insertion space 165 of the sleeve 160. When the support column 360 is inserted into the insertion space 165 of the sleeve 160, the outer surface of the support column 360 may contact the inner surface of the sleeve 160, and since the support column 360 does not have a circular cross section, the sleeve 160 does not allow the support column 360 to rotate relative to each other. Of course, various structures that do not allow the plunger 300 to rotate relative to the rotary disk 100 but allow movement in the longitudinal direction may be used as the first insertion joint and the second insertion joint.

[0075] In an embodiment where a portion of the guide post 180 is configured to be located inside the sleeve 160, a guide groove 365 extending in the longitudinal direction may be formed on the side surface of the support post 360. In this case, the guide groove 365 may have a shape corresponding to a portion of the guide post 180 and may lead to a guide slit 380 formed on the retaining plate 310 of the plunger 300 at the upper portion of the support post 360. That is, as Fig.10 As shown, when the plunger 300 is viewed from below, the guide groove 365 may coincide with a portion of the guide slit 380 .

[0076] Fig.11 is along Figure 3 A cross-sectional view of the grinding container 1000 taken along the line AA'. Fig.11 , when the plunger 300 is coupled to the turntable 100, the support column 360 is inserted into the inner side of the sleeve 160, that is, the insertion space 165, and while the guide column 180 is inserted into the guide slit 380 of the retaining plate 310, the inner side of the guide column 180 is inserted into the guide groove 365 formed on the side surface of the support column 360. Such a structure can effectively prevent the plunger 300 from rotating relative to the turntable 100 while allowing the plunger 300 to move in the longitudinal direction relative to the turntable 100, thereby firmly supporting and aligning the plunger 300.

[0077] The cutting plate 400 may be located at the upper portion of the container body 200 and cover the installation space 215 for accommodating the contents (not shown), and may also use the cutting blades 412 and 414 to crush the contents (not shown) and provide them to the user. Fig.12 and Fig.13 , the cutting plate 400 may include a cover plate 410 , a protruding edge 420 , an outer coupling edge 430 , and an inner coupling edge 440 .

[0078] The cover plate 410 may correspond to the main part of the cutting plate 400 and cover the open upper part of the installation space 215. Cutting blades 412 and 414 configured to crush solid contents (not shown) are provided on the bottom surface of the cover plate 410, and discharge holes 415 and 417 are formed on the cover plate 410 itself to penetrate the cover plate 410 in the longitudinal direction in a manner of discharging the crushed solid contents (not shown). Although the cover plate 410 is shown in the figure as having a circular shape and the cutting plate 400 is a part that rotates relative to the rotary disk 100, the cover plate 410 does not necessarily have to have a circular shape as long as the plunger 300 and the contents (not shown) relative to the cutting plate 400 can rotate.

[0079] According to an embodiment of the present invention, each cutting blade 412, 414 may be disposed adjacent to the corresponding discharge hole 415, 417. Therefore, when the cutting blades 412, 414 partially crush the solid contents (not shown), the crushed contents may be immediately provided to the upper surface of the cover plate 410 through the adjacent discharge holes 415, 417.

[0080] In the example shown in the figure, the cutting plate 400 has a main cutting edge 412 and an auxiliary cutting edge 414. The main cutting edge 412 and the discharge hole 415 adjacent thereto extend long from the edge of the cover plate 410 toward the inside along the first direction, and extend to a position passing through the center of the cover plate 410 based on the first direction. Here, the center of the cover plate 410 can be regarded as substantially the same as the center of the cutting plate 400, and corresponds to the rotation center of the relative rotation relative to the plunger 300 and the content (not shown). If the cutting edge 412 extends to a position less than the center of the cover plate 410, there is a concern that the solid content (not shown) cannot be crushed below the central part of the cover plate 410, resulting in a concern that the top of the solid content (not shown) cannot maintain a uniform height, which may lead to problems such as the inability to provide the content even if the rotating turntable 100 is rotated due to the inability to crush the content, or the uncrushed part of the content excessively presses the cover plate 410.

[0081] The auxiliary cutting edge 414 and the discharge hole 417 adjacent thereto may extend long from the edge of the cover plate 410 toward the inside along the second direction, or they may extend only to a position not passing through the center of the cover plate 410 based on the second direction. The auxiliary cutting edge 414 may crush the contents behind the main cutting edge 412.

[0082] In the example shown in the figure, the cutting edges 412 and 414 extend along virtual straight lines, respectively. Of course, the cutting edges 412 and 414 do not have to be formed in a straight line, but can also be formed along a curve. When the cutting edges 412 and 414 are along a virtual straight line, the corresponding straight line can be configured not to pass through the center of the cover plate 410. Such a configuration enables these cutting edges to extend to a position passing through the center of the cover plate 410 when a plurality of cutting edges 412 and 414 are provided.

[0083] The protruding edge 420 may protrude upward from the edge of the cover plate 410. Since the cover plate 410 is provided with cutting edges 412, 414, it is possible to prevent the protruding edge 420 from protruding upward and making it too easy for surrounding objects to contact the cutting edges 412, 414. The protruding edge 420 may also be used to combine the top cover 500 with the cutting plate 400, and for this purpose, a combining protrusion 422 may be formed on the outer peripheral surface of the protruding edge 420.

[0084] The outer bonding edge 430 and the inner bonding edge 440 may extend downward from the lower portion of the cutting plate 400, and the outer bonding edge 430 may have a larger diameter than the inner bonding edge 440, thereby forming a gap between the outer bonding edge 430 and the inner bonding edge 440. The outer bonding edge 430 and the inner bonding edge 440 may be used to bond the cutting plate 400 to the container body 200 and stably support it. For example, the inner bonding edge 440 of the cutting plate 400 may be inserted into the gap between the outer bonding edge 220 and the inner bonding edge 230 of the container body 200, and the outer bonding edge 220 of the container body 200 may be inserted into the gap between the outer bonding edge 430 and the inner bonding edge 440.

[0085] A coupling groove and / or a fixing groove may be formed on at least one of the outer coupling edge 430 and the inner coupling edge 440. For example, a coupling groove may be formed on the inner circumferential surface of the outer coupling edge 430. When the cutting plate 400 is coupled to the container body 200, the coupling protrusion 222 of the container body 200 may be inserted into the coupling groove formed on the outer coupling edge 430 of the cutting plate 400 to prevent the cutting plate 400 from being separated from the container body 200 in the longitudinal direction.

[0086] In the example shown in the figure, a fixing groove 434 is also formed on the inner circumferential surface of the outer coupling edge 430. The fixing groove 434 can be formed at one or more designated positions on the inner circumferential surface of the outer coupling edge 430. When the cutting plate 400 is coupled to the container body 200, the fixing protrusion 224 of the container body 200 can be inserted into the fixing groove 434 of the cutting plate 400, thereby preventing the cutting plate 400 from rotating relative to the container body 200. Although it is described above that the coupling protrusion 222 and the fixing protrusion 224 are formed on the container body 200, and the corresponding coupling groove and the fixing groove 434 are formed on the cutting plate 400, the positions of the protrusions and the grooves can obviously be changed.

[0087] The cutting plate 400 may be coupled to the upper portion of the container body 200 in such a manner that it does not rotate relative to the container body 200. When using the grinding container 1000, the user may generally rotate the turntable 100 with one hand and the container body 200 with the other hand in opposite directions. The cutting plate 400 may be coupled to the container body 200 in a structure that does not allow relative rotation, and thus may rotate together with the container body 200.

[0088] The top cover 500 may be detachably coupled to at least one of the container body 200 and the cutting plate 400, and serves to cover the cutting plate 400. Figures 1 to 3 as well as Fig.14 , the top cover 500 may include a disc 510 , a side wall 520 , a receiving groove 530 , and a spatula 550 .

[0089] The disk 510 is the main part of the top cover 500 and can form the upper surface of the top cover 500. The disk 510 can be formed to have a size and shape capable of completely covering the cover plate 410.

[0090] The side wall 520 can extend downward from the edge of the disk 510. A coupling groove 522 can be formed on the inner circumferential surface of the side wall 520. When the top cover 500 is coupled to the cutting plate 400, as the coupling protrusion 422 of the cutting plate 400 is inserted into the coupling groove 522, the top cover 500 can be detachably coupled.

[0091] The storage groove 530 is a groove formed on the upper surface of the disk 510 corresponding to the part for storing the spatula 550. The storage groove 530 can be open upward and can also be open forward. On both sides of the storage groove 530, the upper part can protrude inward.

[0092] The spatula 550 can generally have a flat shape and is a tool that can be used by the user to apply the content to the target part as needed. On both sides of the spatula 550, locking portions 560 with the lower part protruding outward can be formed, and on the front side of the spatula 550, a stopper 570 with the lower part protruding downward can be formed.

[0093] When the spatula 550 is stored in the storage groove 530, the locking portions 560 of the spatula 550 are locked to both sides of the storage groove 530, thereby preventing the spatula 550 from disengaging longitudinally. It can be configured such that when the spatula 550 is stored all the way to the rear, the stopper 570 on the front side touches the side wall 520 of the top cover 500.

[0094] Next, with reference to Figures 1 to 14 The assembly process of the grinding container 1000 according to an embodiment of the present invention will be described in more detail.

[0095] After manufacturing each component of the grinding container 1000 separately, the plunger 300 can be inserted into the installation space 215 through the open upper part of the container body 200. The holding plate 310 of the plunger 300 remains in the installation space 215 above the sleeve cylinder 250, and the rod 350 of the plunger 300 can be inserted into the operation passage 255 through the open upper part of the sleeve cylinder 250. At this time, when the plunger 300 is rotated in a state where the engaging protrusion 252 of the sleeve cylinder 250 is engaged with the thread 352 of the rod 350, as the engaging protrusion 252 moves along the thread 352, the plunger 300 can descend.

[0096] The turntable 100 may be coupled to the lower portion of the container body 200, and may be coupled after the plunger 300 is completely lowered, or may be coupled before the plunger 300 is completely lowered. When the turntable 100 is coupled, the guide post 180 of the turntable 100 may be pressed upward in a state of being inserted into the guide groove 365 formed on the support post 360 of the plunger 300 or the guide groove 365 of the support post 360 and the guide slit 380 of the retaining plate 310. When the turntable 100 is pressed upward, the lower portion of the coupling protrusion 256 formed on the outer circumferential surface of the sleeve cylinder 250 contacts the upper portion of the coupling protrusion 136 formed on the inner circumferential surface of the coupling edge 130 of the turntable 100.

[0097] Here, when the rotary disk 100 is further pressed upward, as the coupling edge 130 retreats outward, the coupling protrusion 256 of the sleeve cylinder 250 passes over the coupling protrusion 136 of the coupling edge 130, and the coupling protrusions 136 and 256 are engaged with each other. An inclined portion or a curved portion is formed at the upper portion of the coupling protrusion 136, and an inclined portion or a curved portion is also formed at the lower portion of the coupling protrusion 256, so that it is not difficult for the coupling protrusion 256 of the sleeve cylinder 250 to pass over the coupling protrusion 136 of the coupling edge 130, and a residual slit 115 is formed on the inner side of the coupling edge 130, so that it is not difficult for the coupling edge 130 to retreat outward.

[0098] When the turntable 100 is properly combined, the side wall 120 of the turntable 100 contacts the boss 244 below the main housing 210 and the outer peripheral surface of the support portion 240, the alignment protrusion 254 formed on the outer peripheral surface of the sleeve cylinder 250 contacts the reinforcing rib 140 of the turntable 100, and the upper end of the coupling edge 130 of the turntable 100 contacts the lower surface of the support portion 240. This structure can help the turntable 100 maintain an aligned state relative to the container body 200. In addition, when the turntable 100 is properly combined, the coupling protrusion 136 of the coupling edge 130 is engaged with the coupling protrusion 256 of the sleeve cylinder 250, so that the turntable 100 cannot be separated in the longitudinal direction, but can rotate relative to the container body 200.

[0099] In the grinding container 1000, the plunger 300 is Figure 3 When the configuration shown is in the lowest possible position within the installation space 215, the lower end of the rod 350 of the plunger 300 can contact the disk 110 of the turntable 100, and the upper end of the sleeve cylinder 250 of the container body 200 can be located in the alignment groove 315 formed on the bottom surface of the retaining plate 310.

[0100] The guide post 180 of the turntable 100 may extend to a predetermined position in the installation space 215 through the guide slit 380 of the holding plate 310. Although not shown, a solid content (not shown) is provided above the holding plate 310, and the guide post 180 may extend to the inside of the content (not shown). When manufacturing the grinding container 1000, the solid content (not shown) may be inserted into the installation space 215 after being prepared separately, or may be solidified at a corresponding position after being supplied above the holding plate 310 in the form of liquid or the like.

[0101] After the contents (not shown) are supplied to the installation space 215, the cutting board 400 may be coupled to the upper portion of the container body 200. When the cutting board 400 is pressed downward in a state where the fixing groove 434 of the cutting board 400 is aligned with the fixing protrusion 224 of the container body 200, the inner coupling edge 440 of the cutting board 400 may be inserted into the gap between the outer coupling edge 220 and the inner coupling edge 230, and the outer coupling edge 220 of the container body 200 may be inserted into the gap between the outer coupling edge 430 and the inner coupling edge 440. As the coupling protrusion 222 formed in the container body 200 is inserted into the coupling groove formed on the cutting board 400, the cutting board 400 may be fixed to the container body 200, and the fixing protrusion 224 inserted into the fixing groove 434 may fix the cutting board 400 so that it cannot rotate relative to the container body 200.

[0102] The top cover 500 storing the spatula 550 is connected to the upper part of the assembly of the turntable 100, the container body 200, the plunger 300 and the cutting plate 400. The spatula 550 can be inserted into the storage groove 530 by pressing from the front to the rear of the top cover 500.

[0103] Refer to the following Figures 1 to 14 The use process of the grinding container 1000 according to one embodiment of the present invention is described in more detail.

[0104] When the user wants to use the grinding container 1000, the user can first separate the top cover 500 to expose the cutting plate 400. The user can hold the container body 200 with one hand and hold the rotary disk 100 with the other hand. When the user rotates the rotary disk 100, due to the engagement between the first insertion joint portion and the second insertion joint portion, the rotation of the rotary disk 100 is transmitted to the plunger 300, so that the plunger 300 rotates relative to the container body 200 together with the rotary disk 100.

[0105] Since the plunger 300 and the container body 200 are threadedly connected with the thread 352 through the engaging protrusion 252, as the plunger 300 rotates relative to the container body 200, the engaging protrusion 252 moves along the thread 352, and the retaining plate 310 of the plunger 300 gradually moves upward in the installation space 215.

[0106] When the holding plate 310 moves upward, the content (not shown) supplied to the upper surface of the holding plate 310 moves upward together and contacts the bottom surface of the cover plate 410. The cutting plate 400 is fixed in a manner not to rotate relative to the container body 200, and the plunger 300 is fixed in a manner not to rotate relative to the turntable 100, and the container body 200 and the turntable 100 rotate relative to each other, so from the perspective of the plunger 300, it rotates relative to the holding plate 310 with the same force as the user rotates the turntable 100. In this way, the cutting edges 412 and 414 of the cover plate 410 that rotates relative to the holding plate 310 scrape and crush the upper surface of the solid content (not shown), and the crushed content can be provided to the upper surface of the cover plate 410 through the discharge holes 415 and 417 along the cutting edges 412 and 414. For example, the user can apply the crushed content to the target part using a spatula 550 provided on the top cover 500.

[0107] When the user rotates the dial 100, the abutment portion 330 of the plunger 300 elastically contacts the main shell 210 of the container body 200, and the connection portion 320 and the connection flange 322 between the retaining plate 310 and the abutment portion 330 can absorb excessive stress to a certain extent when it occurs.

[0108] The diameter of the rod 350 of the plunger 300 and the sleeve 250 of the container body 200 is configured to be more than 1 / 2 of the diameter of the retaining plate 310 of the plunger 300, so that the plunger 300 can maintain a stable alignment even if a solid content (not shown) of considerable weight is placed on the retaining plate 310. The structure of the support column 360 and the guide groove 365, as well as the sleeve 160 and the guide column 180 can provide a very strong connection between the plunger 300 and the turntable 100, and further, the rod 350 of the plunger 300 and the sleeve 250 of the container body 200 can help maintain a stable alignment. The coupling edge 130 and the reinforcing rib 140 of the turntable 100 help maintain the turntable 100 aligned with the sleeve 250 of the container body 200.

[0109] On the other hand, the margin slit 115 formed inside the coupling edge 130 in the dial 100 prevents the dial 100 from having an overly rigid structure, thereby preventing stress from concentrating on a certain portion of the dial 100 and the sleeve cylinder 250 when the user rotates the dial 100. In addition, since the contact portion 330 provided at the edge of the plunger 300 is formed to have a flexible thickness and is connected to the retaining plate 310 through the connecting portion 320 and the connecting flange 322, wear and damage due to excessive stress between the retaining plate 310 and the main housing 210 can be prevented.

[0110] As the user uses the grinding container 1000, the amount of solid content on the plunger 300 decreases, and the plunger 300 gradually moves to an increasingly increased height. As the plunger 300 moves to a higher position, the ratio of the first and second insertion joints provided on the rotary disk 100 and the plunger 300 overlapping each other decreases, so that the force of the first insertion joint (e.g., sleeve 160) of the rotary disk 100 to fix the second insertion joint (e.g., support column 360) may decrease. However, the guide column 180 extends to the inside of the installation space 215, and even if the retaining plate 310 of the plunger 300 moves to a position higher than the upper end of the guide column 180, the guide column 180 maintains a state of being inserted into the guide groove 365, so the plunger 300 and the content (not shown) thereon can be maintained in an aligned state by the guide column 180. In particular, since the fact that the plunger 300 reaches an increased height means that the weight of the content (not shown) is reduced, the plunger 300 and the content (not shown) can be fully supported only by the guide column 180.

[0111] Although the present invention has been described above with reference to an embodiment, it will be appreciated by those skilled in the art that various modifications and variations may be made to the present invention without departing from the spirit and scope of the invention as described in the following claims.
