Abstract
Description
Technical Field
[0001] The present invention relates to a container for accommodating a solid product, and specifically to a grinding container capable of grinding and providing a solid product.
Background Art
[0002] Products of some functional compositions are manufactured and distributed from a solid substance of a predetermined volume. When the composition is provided in a solid form, there is an advantage that there is no problem of pouring or leaking from the container like a liquid product, but it may be more difficult to apply it to a required part compared to a liquid product. In recent years, in order to make solid products easier to use, a grinding container has been developed in which a cutter blade is provided on the container itself, and after grinding the solid product, the ground powder is discharged.
[0003] In a grinding container, some components are fixed and some rotate, and relative movement frequently occurs between the components. Also, some components should press the solid product upward according to the user's operation. In such a structure, the product can be correctly used only when the components are kept in a completely aligned state at a fixed position. However, if the part supporting the moving components is made overly rigid, stress will concentrate, which may cause wear and damage to that part. If the part supporting the moving components is made overly flexible, the contents to be supported may not be able to maintain a correctly aligned state, and there is a risk that the grinding operation may not be correctly performed.
Summary of the Invention
Problems to be Solved by the Invention
[0004] Therefore, the present invention is derived to solve the above-mentioned problems, and the object of the present invention is to provide a grinding container that can keep the contents in a stable aligned state while making the part supporting the moving components have an appropriate degree of flexibility.
[0005] Another object of the present invention is to provide a grinding container that can be used conveniently by the user.
[0006] Further objects of the present invention will become clearer based on the embodiments described below. [Means for solving the problem]
[0007] To achieve the above objectives, a grinding container according to one aspect of the present invention includes a container body comprising a main shell and a socket cylinder, wherein the main shell has an internal mounting space that is open at the top, and the socket cylinder is located in the lower inner part of the main shell, extends a predetermined length along the longitudinal direction, has an internal operating passage, and is configured to communicate the mounting space with the outside; a piston configured to be movable relative to the container body along a perpendicular direction, with at least a portion of it positioned within the mounting space to support solid contents, having a longitudinally penetrating guide slit formed on its upper surface; a dial configured to be rotatably coupled to the lower part of the container body and having a guide column that extends upward into the interior of the mounting space, the guide column being inserted into the guide slit via the operating passage, and its upper end positioned within the mounting space; and a cutter plate coupled to the upper part of the container body so as to cover the upper part of the mounting space, having a cutter blade formed on its bottom surface configured to grind the solid contents, and having a longitudinally penetrating discharge hole formed so as to discharge the ground solid contents.
[0008] The grinding vessel according to the present invention may comprise one or more of the following embodiments. For example, the piston includes a stem extending downward and at least a portion of which is located within the operating passage, and either the inner surface of the socket cylinder or the outer surface of the stem is provided with threads, while the other surface of the inner surface of the socket cylinder or the outer surface of the stem is provided with a meshing projection that engages with the threads.
[0009] The dial includes a first insertion engagement portion extending upward, and the piston may include a second insertion engagement portion extending downward. Here, either the first or second insertion engagement portion includes a sleeve that forms an insertion space inside it, and the other of the first or second insertion engagement portion may include a support column that is inserted into the insertion space of the sleeve. In this case, the support column has a non-circular cross-section to prevent the piston from rotating relative to the dial, but may allow the piston to move relative to the dial in the longitudinal direction.
[0010] When the first insertion engagement portion includes the sleeve and the second insertion engagement portion includes the support column, a portion of the guide column can be located inside the sleeve, and a guide groove into which the guide column is inserted can be formed on the side surface of the support column.
[0011] The dial may include multiple guide columns, and the dial may include reinforcing walls that extend upward from its lower surface and connect the lower parts of the multiple guide columns to one another.
[0012] The socket cylinder may have a lower portion that extends below the main shell, and the dial may include an engaging rim that rotatably connects to the lower portion of the socket cylinder. The dial may have a clearance slit formed on the inside of the engaging rim.
[0013] The cutter blade extends inward from the edge of the cutter plate along a first direction, and can extend to a position that passes through the center of the cutter plate with respect to the first direction.
[0014] The cutter blade can be configured to extend along a virtual straight line on the cutter plate, and such a virtual straight line does not pass through the center of the cutter plate.
[0015] The grinding container may further include an overcap that is detachably attached to at least one of the container body and the cutter plate. The overcap may be equipped with a spatula that is detachably attached. [Effects of the Invention]
[0016] The means for solving the problems of the present invention as described above can be expected to have various effects, including the following. However, the present invention is not established only when all of the following effects are achieved.
[0017] According to one embodiment of the present invention, a grinding container is provided that can be used conveniently by the user, in which the part supporting the moving components has an appropriate degree of flexibility while the contents can be kept in a stable and aligned state.

Embodiments for Carrying Out the Invention
[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing with reference to the accompanying drawings, regardless of the reference numerals, the same or corresponding components are given the same reference numerals, and duplicate descriptions thereof are omitted.
[0020] For the sake of convenience of explanation, in this specification, expressions such as "inside", "outside", "upper side", and "lower side" 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 far from the inside of the grinding container 1000. "Upper side" and "lower side" are based on the case where the grinding container 1000 is arranged as shown in FIGS. 1 to 3, and "vertical direction" refers to the up-and-down direction. Of course, when actually using the grinding container 1000 according to an embodiment of the present invention, the upper side direction mentioned in the specification may not coincide with the actual upper side direction.
[0021] Figures 1, 2, 3, and 11 illustrate a grinding vessel 1000 according to one embodiment of the present invention. As shown in the figures, the grinding vessel 1000 according to one embodiment of the present invention may include a dial 100, a vessel body 200, a piston 300, a cutter plate 400, and an overcap 500. Figures 4 and 5 show the dial 100 in more detail, and Figures 6 and 7 show the vessel body 200 in more detail. Figures 8, 9, and 10 show the piston 300 in more detail. Figures 12 and 13 show the cutter plate 400 in more detail, and Figure 14 shows the overcap 500 in more detail.
[0022] The dial 100 corresponds to the part that the user grips and operates to utilize the grinding container 1000, and for this purpose is rotatably coupled to the bottom of the container body 200. Referring to Figures 1 to 5, the dial 100 may include a disc 110, a side wall 120, an engagement rim 130, a reinforcing rib 140, a first insertion engagement part, a reinforcing wall 170, and a guide column 180.
[0023] The disc 110 forms the lower surface of the dial 100 and can serve as a base for other components of the dial 100. In one preferred embodiment, the disc 110 can be formed to be the size and shape necessary to cover the lower part of the socket cylinder 250 of the container body 200. In the figure, the disc 100 of the dial 100 is shown as having a circular shape, and the dial 100 is the part that is rotated by the user, but the disc 110 does not necessarily have to be circular.
[0024] Multiple clearance slits 115 can be formed in the disc 110. Each clearance slit 115 may be formed in an arc shape, at least in part, and may be formed on the inside of the engagement rim 130. In one preferred embodiment of the present invention, the clearance slits 115 can be formed adjacent to each of the multiple engagement rims 130.
[0025] The side wall 120 can extend upward from the edge of the disc 110. The length of the upward extension of the side wall 120 can be determined so that when the dial 100 is coupled to the container body 200, the upper end of the side wall 120 contacts or is adjacent to the main shell 210 of the container body 200. The position and size of the side wall 120 can also be determined so that its outer surface is continuous with the outer surface of the main shell 210. The side wall 120 can be formed along the entire edge of the disc 110 and to cover its inner surface.
[0026] The engaging rim 130 can extend upward from the disc 110 at a position corresponding to the socket cylinder 250, and an engaging projection 136 can be formed on the upper part of the engaging rim 130. The dial 100 may include a plurality of engaging rims 130, each of which may have an arc-shaped cross-section centered on the center of the disc 100. The engaging rim 130 may have a slope that inclines inward as it extends upward, as shown in Figure 3.
[0027] Furthermore, the engagement rim 130 has a shorter length at its upper part than at its lower part, and when the shape of the engagement rim 130 is projected laterally, it can take on a trapezoidal shape. The engagement projection 136 is formed on the upper part of the engagement rim 130, but preferably it is not formed across the entire upper part of the engagement rim 130, and the engagement rim 130 can be configured so that there are portions on both sides of the upper part where the engagement projection 136 is not formed.
[0028] As described above, the clearance slits 115 can be formed adjacent to each of the engagement rims 130. For example, as shown in Figure 4, both the engagement rims 130 and the clearance slits 115 can be formed in an arc shape centered on the center of the disc 100, and the clearance slits 115 can be formed inside the engagement rims 130 with a length corresponding to the engagement rims 130.
[0029] The reinforcing rib 140 can connect adjacent engaging rims 130 at the lower part of the engaging rim 130. That is, the reinforcing rib 140 extends upward from the disc 110, but both ends can be connected to the lower part of the engaging rim 130. The reinforcing rib 140 can also have an arc-shaped cross-section centered on the center of the disc 100.
[0030] In the example shown in Figure 3, the inner surface of the reinforcing rib 140 has a smaller radius of curvature than the inner surface of the engaging rim 130, and the outer surface of the reinforcing rib 140 has a larger radius of curvature than the inner surface of the engaging rim 130, but smaller than the outer surface of the engaging rim 130. The ends on both sides of the reinforcing rib 140 can be formed to overlap the corresponding ends of the engaging rim 130. As described above, engaging projections 136 do not need to be formed on both sides of the upper part of the engaging rim 130, and preferably, the engaging projections 136 can be configured not to be formed on the portion where the reinforcing rib 140 is formed.
[0031] The dial 100 may include a first insertion engagement portion, which may extend upward from the disc 110. The first insertion engagement portion is configured to engage with a second insertion engagement portion formed on the piston 300, and either the first or second insertion engagement portion may include a sleeve, while the other may include a support column. In the example shown in the figure, the first insertion engagement portion formed on the dial 100 is embodied in a form that includes a sleeve 160, and the second insertion engagement portion formed on the piston 300 is embodied in a form that includes a support column 360.
[0032] The sleeve 160 extends upward from the disc 110, is hollow inside, and can form an insertion space 165 on its interior. Therefore, the insertion space 165 can be open to the top and can accommodate a support column 360 inserted from the top to the bottom. 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 prism.
[0033] The reinforcing wall 170 can more firmly fix the guide columns 180 by connecting multiple guide columns 180 to each other at the lower part of the guide column 180. The reinforcing wall 170 can extend upward in an annular shape from the disc 110 and can be connected to the lower part of the outer end of each guide column 180. The reinforcing wall 170 can also have a connecting portion 172 formed thereon that connects to a first insertion engagement portion (e.g., a sleeve 160), thereby further firmly fixing the first insertion engagement portion (e.g., a sleeve 160).
[0034] The guide column 180 can extend upward from a position other than the center of the disc 110. In a preferred embodiment of the present invention, the dial 100 may include a plurality of guide columns 180, and the guide columns 180 may have a flat side shape. As in the example shown in Figure 11, the guide column 180 can extend along a virtual straight line whose cross-section passes through the center of the disc 110. That is, each guide column 180 may be positioned with its inner side toward the rotation center of the dial 100, and the relatively wide side of the guide column 180 may face in a direction that resists rotation. Such a shape of the guide column 180 can help prevent the piston 300 from rotating relative to the dial 100.
[0035] When the first insertion engagement portion includes a sleeve 160, a portion of each guide column 180 may be located inside the sleeve 160, and the other portion may be located outside the sleeve 160. That is, in a preferred embodiment of the present invention, the guide column 180 can be embodied in a shape that intersects the sleeve 160, as shown in Figure 4. Such a structure allows for a very robust and stable engagement between the first insertion engagement portion (i.e., the sleeve 160) and the second insertion engagement portion (i.e., the support column 360).
[0036] Referring to Figure 3, the guide column 180 can pass through the guide slit 380 formed in the holder plate 310 of the piston 300. A solid contents (not shown) is placed on the holder plate 310 of the piston 300, and since the guide column 180 extends through the holder plate 310, a guide slit of the same size and shape as the guide slit 380 can be formed in the solid contents (not shown) placed on the holder plate 310.
[0037] The container body 200 is the main part of the grinding container 1000 and can form the body to which other components are joined, and can contain contents (not shown) inside. Referring to Figures 6 and 7, the container body 200 may include a main shell 210, an outer engagement rim 220, an inner engagement rim 230, a support portion 240, and a socket cylinder 250.
[0038] The main shell 210 can form the main part of the container body 200 and may have a cylindrical shape overall. The main shell 210 can form a mounting space 215 inside it, which can house the piston 300 and solid contents (not shown) placed on top of it. As shown in the example in the figure, the main shell 210 can form part of the exterior of the grinding container 1000.
[0039] In one embodiment of the present invention, a ledge 212 can be formed on the upper part of the main shell 210. In the portion where the ledge 212 is formed, the main shell 210 can have a stepped jaw formed on its upper part as the outer diameter increases. Such a shape of the ledge 212 can provide space on the upper surface of the ledge 212 for an outer engagement rim 220 and an inner engagement rim 230.
[0040] The outer engaging rim 220 and the inner engaging rim 230 can extend upward from the upper surface of the ledge 212 of the main shell 210, and the outer engaging rim 220 has a larger diameter than the inner engaging rim 230, allowing a gap to be formed between the outer engaging rim 220 and the inner engaging rim 230. The outer engaging rim 220 and the inner engaging rim 230 can be used to connect and stably support the cutter plate 400 to the container body 200. For example, the inner engaging rim 440 of the cutter plate 400 can be inserted into the gap between the outer engaging rim 220 and the inner engaging rim 230.
[0041] At least one of the outer engaging rim 220 and the inner engaging rim 230 may have an engaging projection and / or a fixing projection. For example, in the example shown in the figure, an engaging projection 222 is formed on the outer circumferential surface of the outer engaging rim 220. The engaging projection 222 extends over most of the outer circumferential surface of the outer engaging rim 220 and can form an annular shape overall. When the cutter plate 400 is coupled to the container body 200, the engaging projection 222 is inserted into an engaging groove formed in the outer engaging rim 430 of the cutter plate 400, preventing the cutter plate 400 from separating from the container body 200 in the longitudinal direction.
[0042] In the example shown in the figure, a fixing projection 224 is formed on the outer circumferential surface of the outer engagement rim 220. The fixing projection 224 can protrude outward from one or more designated positions on the outer circumferential surface of the outer engagement rim 220. When the cutter plate 400 is coupled to the container body 200, the fixing projection 224 can be inserted into a fixing groove 434 formed in the outer engagement rim 430 of the cutter plate 400, thereby preventing the cutter plate 400 from rotating relative to the container body 200.
[0043] The support portion 240 is formed at the lower part of the main shell 210 and connects the main shell 210 to the socket cylinder 250, while also serving to support the dial 110 which is coupled to the container body 200. The support portion 240 has a reduced diameter at the lower part of the main shell 210 and can form a downwardly extending stepped jaw 244 at the lower end of the main shell 210, and the support portion 240 itself can also have a stepped jaw on its lower surface. An inclined surface can be formed on the outer lower part of the support portion 240 so that the side wall 120 of the dial 100 can be easily attached to the support portion 240.
[0044] The socket cylinder 250 is connected to the support portion 240 and can be formed at a designated position on the lower inner side of the main shell 210. The socket cylinder 250 can extend a predetermined length along the longitudinal direction and can form an operating passage 255 inside it. The socket cylinder 250 has a cylindrical shape with an open top and bottom, and the operating passage 255 can connect to the mounting space 215 above and to the outside below. In other words, the socket cylinder 250 can connect the mounting space 215 to the outside through the operating passage 255.
[0045] The operating passage 255 of the socket cylinder 250 provides a passage through which the dial 100, located outside the container body 200, and the piston 300, located inside the container body 200, can interact with each other. In one embodiment of the present invention, the socket cylinder 250 itself can be involved in the operation of the dial 100 and the piston 300, but for example, either the inner surface of the socket cylinder 250 or the outer surface of the stem 350 of the piston 300 may be provided with threads, and the other may be provided with a meshing projection that engages with the threads. In a preferred embodiment, the diameter of the socket cylinder 250 may be designed to be at least half the diameter of the holder plate 310 of the piston 300.
[0046] In the example shown in Figure 6, the engagement projection 252 is formed on the inner circumferential surface of the socket cylinder 250. The engagement projection 252 can be formed in a position close to the upper end of the socket cylinder 250 and can have a shape corresponding to a screw so that it can engage with the thread 352 formed on the stem 350 of the piston 300. Of course, the engagement projection 252 may also be embodied in the form of a screw thread. That is, in one embodiment of the present invention, the engagement projection 252 may be embodied in the form of a screw thread (i.e., a female thread) formed over the entire inner circumferential surface of the socket cylinder 250.
[0047] Referring to Figure 7, an alignment projection 254 can be formed on the outer circumferential surface of the socket cylinder 250, and the alignment projection 254 can be formed on the lower part of the socket cylinder 250. The alignment projection 254 can project outward in an annular shape across the entire outer circumferential surface of the socket cylinder 250, and its lower part can have a gentle slope or bend. When the dial 100 is coupled to the container body 200, the outer side of the alignment projection 254 can contact the reinforcing rib 140 of the dial 100, helping to keep the dial 100 aligned with the container body 200 even while it is rotating. The slope or bend at the lower part of the alignment projection 254 allows the alignment projection 254 to be inserted more easily into the reinforcing rib 140.
[0048] Furthermore, an engaging projection 256 can be formed on the outer circumferential surface of the socket cylinder 250. The engaging projection 256 can project outward in an annular shape across the entire outer circumferential surface of the socket cylinder 250 and can be formed at a higher position than the alignment projection 254, as shown in Figure 7. The lower part of the engaging projection 256 can also have an inclination or bend. When the dial 100 is coupled to the container body 200, the engaging projection 256 can engage with the engaging projection 136 formed on the engaging rim 130 of the dial 100. The engaging projections 136 and 256 on the engaging rim 130 and the socket cylinder 250 allow the dial 100 to rotate relative to the container body 200, but prevent the dial 100 from deviating from the container body 200 in the vertical direction.
[0049] The piston 300 is the part that supports the contents (not shown) and is also the part that moves along the longitudinal direction by user operation. Referring to Figures 8 to 10, the piston 300 may include a holder plate 310, a connecting part 320, a contact part 330, a stem 350, and a second insertion engagement part.
[0050] The holder plate 310 is a portion that supports solid contents (not shown) on its upper surface and may have the shape of a circular plate overall. The contents (not shown) may include compositions for products such as cleansing balm and deodorants and may be supplied onto the holder plate 310 in solid form. To prevent the contents (not shown) from easily separating, the holder plate 310 may have recessed portions (recesses) that are lowered and / or protruding portions (convex portions) that are highered.
[0051] A guide slit 380 can be formed in the holder plate 310, and a similar guide slit can also be formed in the contents (not shown) provided to the holder plate 310. The guide column 180 of the dial 100 can extend upward through the guide slit 380 and can also pass through a portion of the contents (not shown) placed on the holder plate 310.
[0052] An alignment groove 315 can be formed on the bottom surface of the holder plate 310 around the stem 350. The alignment groove 315 can be formed at a position corresponding to the upper end of the socket cylinder 250 of the container body 200, so that when the piston 300 is in its lowest position in the mounting space 215, the upper end of the socket cylinder 250 can be inserted into the alignment groove 315.
[0053] As shown in Figure 3, the connecting portion 320 can extend downward from the edge of the holder plate 310. The connecting portion 320 is the part that connects the contact portion 330 to the holder plate 310, and supports the contact portion 330 at an intermediate height relative to the vertical direction, so that the upper end of the contact portion 330 is in close proximity to the upper surface of the holder plate 310.
[0054] The contact portion 330 can be located on the edge of the piston 300 and can be connected to the lower part of the connecting portion 320 by a connecting flange 322. The contact portion 330 can be formed to a thickness that extends vertically and has some flexibility, and with respect to the midpoint height of the contact portion 330, the upper part of the contact portion 330 can have an outer diameter that increases upwards, and the lower part of the contact portion 330 can have an outer diameter that increases downwards. This allows the contact portion 330 to adhere relatively watertightly to the inner surface of the main shell 310, minimizing leakage of contents (not shown) below the piston 300.
[0055] The stem 350 can extend downward from the bottom surface of the holder plate 310. In one embodiment of the present invention, the diameter of the stem 350 can be designed to be at least half the diameter of the holder plate 310. As described above, in one embodiment of the present invention, either the inner surface of the socket cylinder 250 or the outer surface of the stem 350 may be provided with threads, and the other may be provided with a meshing projection that engages with the threads. In the example shown in the figure, the threads 352 are formed on the outer surface of the stem 350 of the piston 300. When the piston 300 is coupled to the container body 200, the meshing projection 252 of the socket cylinder 250 can engage with the threads 352 of the stem 350. In some embodiments of the present invention, the meshing projection may be formed on the stem 350 and the threads may be formed on the socket cylinder 250.
[0056] In the figure, the stem 350 of the piston 300 is inserted inside the socket cylinder 250, threads 352 are formed on the outer surface of the stem 350, and a meshing projection 252 is formed on the inner surface of the socket cylinder 250. However, in some embodiments of the present invention, the socket cylinder 250 may be inserted inside the stem 350, and threads and meshing projections may be formed on the outer surface of the socket cylinder 250 and the inner surface of the stem 350. Of course, in this case, the length that the stem 350 extends downward can be limited by the position of the support portion 240.
[0057] The second insertion engagement portion can extend downward from the bottom surface of the holder plate 310 and can engage and connect with the first insertion engagement portion of the dial 100 via an operating passage 255 formed in the container body 200. In the example shown in the figure, the first insertion engagement portion formed on the dial 100 is embodied in a form that includes a sleeve 160, and the second insertion engagement portion formed on the piston 300 is embodied in a form that includes a support column 360.
[0058] The sleeve 160 and the support column 360 may have non-circular cross-sections, and the support column 360 may be shaped to be insertable 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 can 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 relative rotation of the support column 360. Of course, various structures can be applied to the first and second insertion engagement parts that allow movement along the vertical direction while preventing the piston 300 from rotating relative to the dial 100.
[0059] In an embodiment where a portion of the guide column 180 is located inside the sleeve 160, a guide groove 365 extending vertically can be formed on the side surface of the support column 360. In this case, the guide groove 365 can have a shape corresponding to a portion of the guide column 180 and can connect from the top of the support column 360 to a guide slit 380 formed in the holder plate 310 of the piston 300. That is, as shown in Figure 10, when the piston 300 is viewed from below, the guide groove 365 can coincide with a portion of the guide slit 380.
[0060] Figure 11 is a cross-sectional view of the grinding container 1000, cut along the line A-A' in Figure 3. Referring to Figure 11, with the piston 300 coupled to the dial 100, the support column 360 is inserted inside the sleeve 160, i.e., into the insertion space 165, and the guide column 180 is inserted into the guide slit 380 of the holder plate 310, with the inside of the guide column 180 inserted into the guide groove 365 formed on the side surface of the support column 360. This configuration allows the piston 300 to move longitudinally relative to the dial 100, while effectively preventing the piston 300 from rotating relative to the dial 100, thereby firmly supporting and aligning the piston 300.
[0061] The cutter plate 400 is located on top of the container body 200 and covers the mounting space 215 that contains contents (not shown), while also serving to crush the contents (not shown) using cutter blades 412 and 414 and provide them to the user. Referring to Figures 12 and 13, the cutter plate 400 may include a cover plate 410, a protruding rim 420, an outer engaging rim 430, and an inner engaging rim 440.
[0062] The cover plate 410 corresponds to the main part of the cutter plate 400 and can cover the open upper part of the mounting space 215. The bottom surface of the cover plate 410 is provided with cutter blades 412 and 414 configured to crush solid contents (not shown), and the cover plate 410 itself has discharge holes 415 and 417 that penetrate the cover plate 410 in the vertical direction so that the crushed solid contents (not shown) can be discharged. In the figure, the cover plate 410 is shown as having a circular shape, and the cutter plate 400 is the part that rotates relative to the dial 100, but the cover plate 410 does not necessarily have to be circular as long as the piston 300 and the contents (not shown) can rotate relative to the cutter plate 400.
[0063] According to one embodiment of the present invention, each cutter blade 412, 414 can be positioned adjacent to the corresponding discharge holes 415, 417. Therefore, when the cutter blades 412, 414 partially crush the solid contents (not shown), the crushed contents can immediately pass through the adjacent discharge holes 415, 417 and be provided to the upper surface of the cover plate 410.
[0064] In the example shown in the figure, the cutter plate 410 comprises one main cutter blade 412 and one auxiliary cutter blade 414. The main cutter blade 412 and the adjacent discharge hole 415 extend inward from the edge of the cover plate 410 along a first direction, and extend to a position that passes through the center of the cover plate 410 relative to the first direction. Here, the center of the cover plate 410 can be considered substantially equal to the center of the cutter plate 400 and corresponds to the center of rotation of the piston 300 and the contents (not shown). If the cutter blade 412 extends only to a position that does not reach the center of the cover plate 410, the contents (not shown) below the central portion of the cover plate 410 may not be crushed, and the top surface of the solid contents (not shown) may not maintain a uniform height. This may lead to problems such as the contents not being crushed and dispensed even when the dial 100 is rotated, or the uncrushed portion of the contents excessively pressing against the cover plate 410.
[0065] The auxiliary cutter blade 414 and the adjacent discharge hole 417 can extend inward along the second direction from the edge of the cover plate 410, and they may extend only to a position that does not pass through the center of the cover plate 410 with respect to the second direction. The auxiliary cutter blade 414 can crush the contents behind the main cutter blade 412.
[0066] In the example shown in the figure, each of the cutter blades 412 and 414 extends along a virtual straight line. Of course, the cutter blades 412 and 414 do not necessarily have to be formed in a straight line; they may be formed along a curve. When the cutter blades 412 and 414 extend along a virtual straight line, the line can be positioned so that it does not pass through the center of the cover plate 410. Such an arrangement allows multiple cutter blades 412 and 414 to extend to a position that passes through the center of the cover plate 410.
[0067] The protruding rim 420 can protrude upward from the edge of the cover plate 410. Since the cover plate 410 is equipped with cutter blades 412 and 414, the protruding rim 420 can protrude upward to prevent surrounding objects from coming into excessive contact with the cutter blades 412 and 414. The protruding rim 420 may also be used to connect the overcap 500 to the cutter plate 400, and for this purpose, an engaging projection 522 may be formed on the outer circumferential surface of the protruding rim 420.
[0068] The outer engaging rim 430 and the inner engaging rim 440 can extend downward from the bottom of the cutter plate 400, and the outer engaging rim 430 has a larger diameter than the inner engaging rim 440, allowing a gap to be formed between the outer engaging rim 430 and the inner engaging rim 440. The outer engaging rim 430 and the inner engaging rim 440 can be used to connect and stably support the cutter plate 400 to the container body 200. For example, the inner engaging rim 440 of the cutter plate 400 can be inserted into the gap between the outer engaging rim 220 and the inner engaging rim 230 of the container body 200, and the outer engaging rim 220 of the container body 200 can be inserted into the gap between the outer engaging rim 430 and the inner engaging rim 440.
[0069] An engagement groove and / or fixing groove can be formed in at least one of the outer engagement rim 430 and the inner engagement rim 440. For example, an engagement groove can be formed on the inner circumferential surface of the outer engagement rim 430. When the cutter plate 400 is coupled to the container body 200, the engagement projection 222 of the container body 200 is inserted into the engagement groove formed in the outer engagement rim 430 of the cutter plate 400, preventing the cutter plate 400 from separating from the container body 200 in the longitudinal direction.
[0070] Furthermore, in the example shown in the figure, a fixing groove 434 is formed on the inner circumferential surface of the outer engagement rim 430. The fixing groove 434 can be formed at one or more designated positions on the inner circumferential surface of the outer engagement rim 430. When the cutter plate 400 is coupled to the container body 200, the fixing projection 224 of the container body 200 can be inserted into the fixing groove 434 of the cutter plate 400, thereby preventing the cutter plate 400 from rotating relative to the container body 200. In the above explanation, the engagement projection 222 and the fixing projection 224 are formed on the container body 200, and the corresponding engagement groove and fixing groove 434 are formed on the cutter plate 400, but it goes without saying that the positions of the projections and grooves may be changed.
[0071] Thus, the cutter plate 400 may be coupled to the top of the container body 200 in such a way that it cannot rotate relative to the container body 200. When using the grinding container 1000, the user can generally hold the dial 100 with one hand and the container body 200 with the other hand, and rotate them in opposite directions. The cutter plate 400 is coupled to the container body 200 in a way that does not allow relative rotation, so it can rotate together with the container body 200.
[0072] The overcap 500 can be detachably attached to at least one of the container body 200 and the cutter plate 400, and can serve to cover the cutter plate 400. Referring to Figures 1 to 3 and Figure 14, the overcap 500 may include a disc 510, a side wall 520, a storage groove 530, and a spatula 550.
[0073] The disc 510 can form the upper surface of the overcap 500 as the main part of the overcap 500. The disc 510 can be formed to be the size and shape that can completely cover the cover plate 410.
[0074] The side wall 520 can extend downward from the edge of the disc 510. An engagement groove 522 can be formed on the inner circumferential surface of the side wall 520, so that when the overcap 500 engages with the cutter plate 400, the overcap 500 can be detachably coupled while the engagement projection 422 of the cutter plate 400 is inserted into the engagement groove 522.
[0075] The storage groove 530 is a groove formed on the upper surface of the disc 510 and corresponds to the portion in which the spatula 550 is stored. The storage groove 530 may open upwards and also forwards. On both sides of the storage groove 530, the upper part may protrude inwards.
[0076] The spatula 550 can have a generally flat shape and is a tool that can be used by the user to apply the contents to the target area as needed. Locking portions 560 can be formed on both sides of the spatula 550, with the lower part protruding outward, and a stopper 570 can be formed on the front side of the spatula 550, with the lower part protruding downward.
[0077] When the spatula 550 is stored in the storage groove 530, the locking portion 560 of the spatula 550 catches on both sides of the storage groove 530, preventing the spatula 550 from coming loose in the vertical direction. When the spatula 550 is fully stored to the rear, the front stopper 570 can be configured to abut against the side wall 520 of the overcap 500.
[0078] The process of assembling the grinding container 1000 according to the embodiment of the present invention described above will be explained in more detail below with reference to Figures 1 to 14.
[0079] After each component of the grinding vessel 1000 has been manufactured, the piston 300 can be inserted into the mounting space 215 through the open top of the vessel body 200. The holder plate 310 of the piston 300 remains in the mounting space 215 on the socket cylinder 250, and the stem 350 of the piston 300 can be inserted into the operating passage 255 through the open top of the socket cylinder 250. At this time, when the piston 300 is rotated with the engagement projection 252 of the socket cylinder 250 engaged with the threads 352 of the stem 350, the piston 300 can descend while the engagement projection 252 moves along the threads 352.
[0080] The dial 100 can be coupled to the lower part of the container body 200, and may be coupled after the piston 300 has descended all the way down, or before it has descended completely. When the dial 100 is coupled, the guide column 180 of the dial 100 can be pressed upward while inserted into the guide groove 365 formed in the support column 360 of the piston 300, or into the guide groove 365 of the support column 360 and the guide slit 380 of the holder plate 310. When the dial 100 is pressed upward, the lower part of the engaging projection 256 formed on the outer circumferential surface of the socket cylinder 250 connects to the upper part of the engaging projection 136 formed on the inner circumferential surface of the engaging rim 130 of the dial 100.
[0081] When the dial 100 is pressed further upward, the engaging rim 130 retracts outward, and the engaging projection 256 of the socket cylinder 250 overcomes the engaging projection 136 of the engaging rim 130, causing the engaging projections 136 and 256 to engage with each other. The upper part of the engaging projection 136 has a slope or bend, and the lower part of the engaging projection 256 also has a slope or bend, allowing the engaging projection 256 of the socket cylinder 250 to easily overcome the engaging projection 136 of the engaging rim 130. The inside of the engaging rim 130 has a clearance slit 115, allowing the engaging rim 130 to retract outward without difficulty.
[0082] When the dial 100 is properly engaged, the side wall 120 of the dial 100 contacts the lower stepped jaw 244 and the outer circumferential surface of the support portion 240 of the main shell 210, the alignment projection 254 formed on the outer circumferential surface of the socket cylinder 250 contacts the reinforcing rib 140 of the dial 100, and the upper end of the engagement rim 130 of the dial 100 contacts the lower surface of the support portion 240. Such a structure can help maintain the dial 100 in an aligned state relative to the container body 200. In addition, when the dial 100 is properly engaged, the engagement projection 136 of the engagement rim 130 engages with the engagement projection 256 of the socket cylinder 250, preventing the dial 100 from separating in the longitudinal direction, while allowing it to rotate relative to the container body 200.
[0083] In the grinding vessel 1000, with the piston 300 positioned as low as possible within the mounting space 215 as shown in Figure 3, the lower end of the stem 350 of the piston 300 can contact the master plate 110 of the dial 100, and the upper end of the socket cylinder 250 of the vessel body 200 can be positioned within the alignment groove 315 formed on the bottom surface of the holder plate 310.
[0084] The guide column 180 of the dial 100 can extend through the guide slit 380 of the holder plate 310 to a predetermined position in the mounting space 215. Although not shown, solid contents (not shown) are provided on the holder plate 310, and the guide column 180 can extend into the interior of the contents (not shown). When the grinding container 1000 is manufactured, the solid contents (not shown) may be separately composed and then inserted into the mounting space 215, or they may be supplied on the holder plate 310 in the form of a liquid or the like and then solidified at that position.
[0085] After contents (not shown) are supplied to the mounting space 215, the cutter plate 400 can be attached to the top of the container body 200. When the cutter plate 400 is pressed downward with its fixing groove 434 aligned with the fixing projection 224 of the container body 200, the inner engaging rim 440 of the cutter plate 400 is inserted into the gap between the outer engaging rim 220 and the inner engaging rim 230, and the outer engaging rim 220 of the container body 200 is inserted into the gap between the outer engaging rim 430 and the inner engaging rim 440. The cutter plate 400 can be fixed to the container body 200 as the engaging projection 222 formed on the container body 200 is inserted into the engaging groove formed on the cutter plate 400, and the fixing projection 224 inserted into the fixing groove 434 can fix the cutter plate 400 so that it does not rotate relative to the container body 200.
[0086] An overcap 500 containing a spatula 550 can be attached to the top of the assembly of the dial 100, container body 200, piston 300, and cutter plate 400 configured in this way. The spatula 550 can be pressed from the front to the rear of the overcap 500 and inserted into the storage groove 530.
[0087] The process of using the grinding container 1000 according to the embodiment of the present invention described above will be explained in more detail below with reference to Figures 1 to 14.
[0088] When a user wants to use the grinding container 1000, they can first separate the overcap 500 to expose the cutter plate 400. The user can grasp the container body 200 with one hand and the dial 100 with the other. When the user rotates the dial 100, the rotation of the dial 100 is transmitted to the piston 300 by the engagement between the first insertion engagement part and the second insertion engagement part, and the piston 300 rotates together with the dial 100 relative to the container body 200.
[0089] Since the piston 300 and the container body 200 are screw-connected by the threads 352 and the engaging projection 252, as the piston 300 rotates relative to the container body 200, the engaging projection 252 moves along the threads 352, and the holder plate 310 of the piston 300 gradually moves upward within the mounting space 215.
[0090] As the holder plate 310 moves upward, the contents (not shown) supplied to the upper surface of the holder plate 310 move upward with it and come into contact with the bottom surface of the cover plate 410. The cutter plate 400 is fixed to the container body 200 so as not to rotate, while the piston 300 is fixed to the dial 100 so as not to rotate. Since the container body 200 and the dial 100 rotate relative to each other, from the perspective of the piston 300, the cover plate 410 rotates relative to the holder plate 310 with the same force as when the user rotates the dial 100. The cutter blades 412 and 414 of the cover plate 410, which rotate relative to the holder plate 310 in this way, scrape and pulverize the upper surface of the solid contents (not shown), and the pulverized contents can be carried on the cutter blades 412 and 414 and supplied to the upper surface of the cover plate 410 through the discharge holes 415 and 417. For example, the user can apply the crushed contents to the target area using the spatula 550 provided on the overcap 500.
[0091] When the user rotates the dial 100, the contact portion 330 of the piston 300 elastically contacts the main shell 210 of the container body 200, and the connecting portion 320 and connecting flange 322 between the holder plate 310 and the contact portion 330 can absorb to some extent any excessive stress that may occur.
[0092] The diameter of the stem 350 of the piston 300 and the socket cylinder 250 of the container body 200 are set to be more than half the diameter of the holder plate 310 of the piston 300, so that the piston 300 can maintain a stable aligned state even when a considerable weight of solid contents (not shown) is placed on the holder plate 310. The structure of the support column 360 and guide groove 365, and the sleeve 160 and guide column 180 can provide a very strong connection between the piston 300 and the dial 100, and further can help the stem 350 of the piston 300 and the socket cylinder 250 of the container body 200 to maintain a stable aligned state. The engagement rim 130 and reinforcing rib 140 of the dial 100 help to maintain the dial 100 aligned with the socket cylinder 250 of the container body 200.
[0093] On the other hand, the clearance slit 115 formed inside the engagement rim 130 of the dial 100 prevents the dial 100 from having an excessively rigid structure, thus preventing excessive stress from concentrating on any part of the dial 100 or the socket cylinder 250 when the user rotates the dial 100. In addition, the contact portion 330 provided on the edge of the piston 300 is formed to a flexible thickness and is connected to the holder plate 310 by the connecting portion 320 and the connecting flange 322, so that wear and damage due to excessive stress can be prevented between the holder plate 310 and the main shell 210.
[0094] As the user uses the grinding container 1000, the amount of solid material on the piston 300 decreases, and the piston 300 is gradually positioned at an increasing height. The higher the piston 300 is positioned, the less the first and second insertion engagements on the dial 100 and the piston 300 overlap each other, and the less force the first insertion engagement (e.g., sleeve 160) of the dial 100 has on the second insertion engagement (e.g., support column 360). However, since the guide column 180 extends into the mounting space 215, and the holder plate 310 of the piston 300 moves to a position higher than the upper end of the guide column 180, the guide column 180 remains inserted in the guide groove 365, so that the piston 300 and its contents (not shown) can be kept aligned. In particular, the fact that the piston 300 has reached an increased height means that the weight of the contents (not shown) has decreased, so the piston 300 and the contents (not shown) can be adequately supported by the guide column 180 alone.
[0095] Although the above has been described with reference to one embodiment of the present invention, a person with ordinary skill in the art will understand that the present invention can be modified and altered in various ways without departing from the spirit and scope of the invention as described in the following claims.
