[0098] According to one embodiment, the cap coupling portion (122) may include a first flange portion (1221), an extension portion (1222) extending downward from the first flange portion (1221), and a second flange portion (1223) extending inwardly from the extension portion (1222). In one embodiment, the first flange portion (1221) may be provided to form a step with the upper surface of the detergent cover (120). In one embodiment, the extension portion (1222) may connect the first flange portion (1221) and the second flange portion (1223). In one embodiment, the extension portion (1222) may be inclined with respect to the first flange portion (1221) and the second flange (1223). In one embodiment, a detergent inlet (121) may be formed on the inner side of the second flange portion (1223). For example, the second flange portion (1223) can be extended to surround the detergent inlet (121).

[0099] According to one embodiment, a mounting groove (1221a) may be provided on the upper surface of the first flange portion (1221) in which the second sealing portion (142) is mounted. In one embodiment, the mounting groove (1121a) may be recessed from the upper surface of the first flange portion (1221) and may extend along the inner periphery of the first flange portion (1221).

[0100] According to one embodiment, the second flange portion (1223) may be provided with at least one through-hole (1224) into which a fixing projection (e.g., the fixing projection (133) of FIG. 3) of a cap (e.g., the cap (130) of FIG. 3) is inserted. In one embodiment, the through-hole (1224) may be a portion cut inwardly of the second flange portion (1124). Here, the inside may be in a direction away from the detergent inlet (121). In one embodiment, the number of through-holes (1124) may correspond to the number of fixing projections (133) of the cap (130).

[0101] According to one embodiment, a pair of stoppers (1225) protruding from the bottom surface of the second flange portion (1223) and for fixing the cap (130) may be provided. In one embodiment, the pair of stoppers (1225) may include a first stopper (1225a) disposed adjacent to the through portion (1224) on one side of the through portion (1224), and a second stopper (1225b) spaced apart from the through portion (1224) on the other side opposite to the one side of the through portion (1224). The pair of stoppers (1225) may contact the fixing protrusion (133) inserted into the through portion (1224) when the cap (130) is rotated by a user, thereby limiting the rotation of the cap (130).

[0102] For example, a user can insert a fixing projection (133) of a cap (130) into a penetration portion (1224) of a detergent cover (120), and then rotate the cap (130) in a first rotational direction (e.g., clockwise) so that the fixing projection (133) of the cap (130) comes out of the penetration portion (1224) and comes into contact with a pair of stoppers (1225), thereby fixing the cap (130) to the detergent cover (120). In the case of releasing (or separating) the cap (130), the above-described fixing operation of the cap (130) is performed in the reverse order. For example, a user can release the cap (130) from the detergent cover (120) by rotating the cap (130) in a second rotational direction (e.g., counterclockwise) opposite to the first rotational direction to position the fixing projection (133) of the cap (130) in the penetration portion (1224).

[0103] According to one embodiment, the cap coupling portion (122) may include a plurality of flow paths (1226) that form a flow path for a resin for injection of the second sealing portion (142) of the sealing member (140). In one embodiment, the flow paths (1226) may penetrate the lower portion of the first flange portion (1221) of the cap coupling portion (1222) and communicate with a seating groove (1221a). In one embodiment, the flow paths (1226) may include a first gate (1226a) that is opened downward, a second gate (1226b) that is communicated with the seating groove (1221a), and a guide surface (1226c) that connects the first gate (1226a) and the second gate (1226b). The second gate (1226b) may be opened in an inclined direction with respect to the seating groove (1221a). The above guide surface (1226c) may be inclined relative to the first gate (1226a). For example, the above guide surface (1226c) may be an inclined surface. The flow of resin through the flow path (1226) during injection molding of the sealing member (140) will be described later with reference to FIGS. 9 to 11.

[0104] According to one embodiment, the sealing member (140) may include a first sealing portion (141), a second sealing portion (142), and a plurality of bridge portions (143) connecting the first sealing portion (141) and the second sealing portion (142).

[0105] According to one embodiment, the first sealing portion (141) may be spaced inwardly from the cover flange portion (123) of the detergent cover (120) and may extend along the lower edge of the detergent cover (120). In one embodiment, the first sealing portion (141) may include a sealing rib (1412) that protrudes from a side surface of the first sealing portion (141) and extends along the perimeter of the first sealing portion (141). In one embodiment, the sealing ribs (1412a, 1412b) may be provided in at least two or more forms as illustrated in this drawing, and may be spaced apart from each other in the vertical direction. When the detergent case (110) and the detergent cover (120) are combined, the sealing ribs (1412a, 1412b) are deformed and pressed against the inner surface of the detergent case (110) as shown in FIG. 4, thereby doubly sealing the gap between the detergent case (110) and the detergent cover (120).

[0106] According to one embodiment, the second sealing portion (142) is seated in the seating groove (1221a) of the first flange portion (1221) and may extend along the circumference of the first flange portion (1221). The second sealing portion (142) may have an overall ring shape. In one embodiment, the weight of the second sealing portion (142) may be designed to be lighter than the weight of the first sealing portion (141).

[0107] According to one embodiment, the bridge portion (143) may have a shape corresponding to the lower portion of the first flange (1221) and / or the lower portion of the detergent cover (120) connected to the first flange portion (1221). In one embodiment, the bridge portion (143) may include a connecting portion (1431) that is recessed from the upper surface of the bridge portion (143) and connected to the second sealing portion (142). The connecting portion (1431) may be referred to as a concave portion. In one embodiment, the connecting portion (1431) may include a flat portion (1431a) and an inclined portion (1431b) that connects the flat portion (1431a) and the second sealing portion (142). In one embodiment, the inclined portion (1431b) may have an upward slope. In one embodiment, the slope (1431b) may have a slope corresponding to the guide surface (1226c) of the euro portion (126).

[0108] FIG. 9 is an enlarged view of part A shown in FIG. 7 according to one embodiment of the present disclosure.

[0109] FIG. 10 is an enlarged view of a portion of a cross-section of a detergent cover with a sealing member combined therewith according to a comparative example of the present disclosure.

[0110] FIG. 11 is an enlarged view of a portion of a plan view of a detergent cover with a sealing member combined therewith according to a comparative example of the present disclosure.

[0111] Fig. 9 is a drawing showing the flow of resin through the flow path (1226). Fig. 10 is a drawing showing a flow path (1226') designed to have a different structure from that of the flow path (1226) of Fig. 9. Fig. 11 is a drawing showing the appearance of the second sealing part (142') after injection is completed through the flow path (1226') of Fig. 10.

[0112] The configuration of the detergent cover (120) and the sealing member (140) of FIG. 9 may be all or partly the same as the configuration of the detergent cover (120) and the sealing member (140) of FIGS. 2 to 8. The configuration of the detergent cover (120) and the sealing member (140') of FIGS. 10 and 11 may be all or partly the same as the configuration of the detergent cover (120) and the sealing member (140') of FIGS. 2 to 9.

[0113] The embodiments illustrated in FIGS. 9 to 11 can be optionally combined with the embodiments illustrated in FIGS. 1 to 10.

[0114] Referring to FIG. 9, during the secondary injection of the sealing member (140), the resin of the sealing member (140) sequentially flows from the first sealing portion (141) to the bridge portion (143) to the second sealing portion (142), and the first sealing portion (141), the bridge portion (143), and / or the second sealing portion (142) are sequentially filled and injection-molded. At this time, when examining the flow of the resin in the portion B, the width (or cross-section) of the flow path portion (1226) is gradually reduced by the inclined structure of the guide surface (1226c), so that the flow decompression section of the resin can be minimized. In this case, it can be confirmed that the resin flowing along the guide portion (1226c) smoothly flows from the first gate (1226a) to the second gate (1226b) and flows into the seating groove (1221a).

[0115] Referring to FIGS. 10 and 11, it can be seen that the flow path part (1226') of the detergent cover (120') according to the comparative example has a guide surface (1226c') having a vertical structure, so that the width (or cross-section) of the flow path is narrower and more constant than that of the flow path part (1226) of FIG. 9, compared to the flow path part (1226) of FIG. 9. In this case, the flow pressure reduction section of the resin flowing into the flow path part (1226') increases more than that of the embodiment of FIG. 9, so that the amount of resin flowing from the first gate (1226a') to the second gate (1226b') and flowing into the settling groove (1221a) decreases. If the amount of resin flowing into the settling groove (1221a) decreases, as illustrated in FIG. 11, the injection of the second sealing member (142') may not be completely performed, resulting in an injection defect.

[0116] FIG. 12 is a cross-sectional view taken along line II-II' of FIG. 5 according to one embodiment of the present disclosure.

[0117] The configuration of the detergent cover (120) and the sealing member (140) of FIG. 12 may be all or part of the same as the configuration of the detergent cover (120) and the sealing member (140) of FIGS. 1 to 11.

[0118] The embodiment of FIG. 12 can be optionally combined with the embodiments of FIGS. 1 to 11.

[0119] Referring to FIG. 12, a detergent cover (120) according to one embodiment may include a fitting rib (124) protruding from a lower surface (120b) and a pair of recesses (125) surrounding both sides of the fitting rib (124).

[0120] According to one embodiment, the first sealing portion (141) of the sealing member (140) may include a fitting groove (1411) in which the fitting rib (124) of the detergent cover (120) is received. In one embodiment, the fitting groove (1411) may be provided at a corresponding position of the fitting rib (124) and may be recessed from the upper surface of the first sealing portion (141).

[0121] According to one embodiment, the fitting rib (124) may be spaced inwardly from the cover flange portion (123). In one embodiment, the fitting rib (124) may protrude vertically toward the lower side of the detergent cover (120) and extend along the lower edge of the detergent cover (120). In one embodiment, the width (w) of the fitting rib (124) may be designed in consideration of the thickness (t) of the detergent cover (120). For example, the width (w) of the fitting rib (124) may be designed to be less than half the thickness (t) of the detergent cover (120). For example, when the thickness (t) of the detergent cover (120) is designed to be 2.8 mm, the width (w) of the fitting rib (124) may be designed to be 1.1 mm. When the width (w) of the above-mentioned fitting rib (124) is designed to be less than half the thickness (t) of the detergent cover (120), when the detergent cover (120) and / or the sealing member (140) are injection-molded, surface shrinkage of the part (e.g., detergent cover (120)) can be reduced (or prevented), and the tension of the sealing member (140) can also be maintained.

[0122] According to one embodiment, a pair of recesses (125) may be arranged on both sides of the fitting rib (124). In one embodiment, the pair of recesses (125) may be recessed a predetermined depth (d) from the lower surface (120b) of the detergent cover (120). In one embodiment, the recessed depth (d) of the recess (125) may be designed in consideration of the width (w) of the fitting rib (124) and the thickness (t) of the detergent cover (120). For example, the recessed depth (d) of the recess (125) may be designed in a range in which the width (w) of the fitting rib (124) is less than or equal to half of the difference between the thickness (t) of the detergent cover (120) and the recessed depth (d) of the recess (125). For example, when injection molding a detergent cover (120) and / or a sealing member (140), if the thickness (t) of the detergent cover (120) is designed to be 2.8 mm and the width (w) of the fitting rib (124) is designed to be 1.1 mm to prevent shrinkage of the part (e.g., the fitting rib (124)), the depression depth (d) of the recess (125) can be designed to be 0.5 mm.

[0123] In one embodiment, a pair of recesses (125) may extend along both sides of the detergent cover (120). While the drawing illustrates a pair of recesses (125a, 125b) surrounding the fitting rib (124), the present disclosure is not limited thereto. For example, in one embodiment, the recess may be provided in the form of a single recess extending along one side of the fitting rib (124).

[0124] FIG. 13 is a flowchart showing a process of removing a detergent cover from an injection mold device according to one embodiment of the present disclosure.

[0125] The configuration of the detergent cover (120) and the sealing member (140) of Fig. 13 may be all or part of the same as the configuration of the detergent cover (120) and the sealing member (140) of Figs. 1 to 12.

[0127] Figure 13 is a process diagram explaining the process of taking out an assembly (C) (hereinafter, injection molded product) in which a detergent cover (120) and a sealing member (140) are integrally injection molded from an injection mold device (800).

[0128] Referring to (a) of Fig. 13, the injection molded product (C) fixed to the molds (810, 820, 830) of the injection molding device (800) has a problem in that it is difficult to remove the product due to interference between the molds caused by the undercut structure (e.g., the sealing rib (1412)) of the sealing member (140).

[0129] Referring to (b) and (c) of FIG. 13, the injection mold device (800) can vertically move the molds (810, 820, 830) in a different order to remove the injection product (C), thereby forming a space (810a) in which the undercut structure (1412) can be pushed inward. For example, as illustrated in (b) of FIG. 13, the injection mold device (800) can vertically move the remaining molds (820, 830) except for the first mold (810) that is in contact with the inside of the sealing member (140) together with the injection product (C). After this, as shown in (c) of FIG. 13, when the third mold (830) except for the second mold (820) that is engaged with the undercut structure (1412) of the sealing member (140) is vertically moved together with the injection-molded product (C), the undercut structure (1412) is pushed into the inner space (810a) of the sealing member (140) that was occupied by the first mold (810), the bond with the second mold (820) is released, and the injection-molded product (C) becomes possible to be taken out.
