Description

[Technical field]

[0001] The present invention relates to an applicator container having a container and an applicator with a cap, and a method for manufacturing the applicator container. [Background technology]

[0002] In an application container for mascara or the like, a cap body, a shaft, and an application tool are generally provided on the cap side, and a squeeze part is provided at the mouth of the container body on the container side.

[0003] In such an applicator container, when an applicator impregnated with cosmetic liquid such as mascara liquid is removed, the applicator comes into contact with the squeezing part, thereby removing excess cosmetic material. For this reason, the squeezing part is often made of flexible rubber or elastomer such as NBR or LLDPE, which is soft when it comes into contact with the applicator (for example, Patent Document 1). The container body is made of hard PP or the like.

[0004] On the other hand, on the cap side, the applicator is, for example, a brush or spatula, and the brush is made of a combination of SUS and PA, bristles, or flexible synthetic resin (elastomer) such as PBT, PBA, etc. On the other hand, the cap body is made of, for example, hard PP, etc. Furthermore, the shaft is made of, for example, PBA, PA, PP, etc.

[0005] In this way, when the cap and the container are made of a plurality of materials, the manufacturing process becomes complicated due to the large number of parts.

[0006] Therefore, for example, Patent Document 2 proposes that on the container 90 side, the squeezing portion 94 is integrally formed from the same material as the storage portions 91, 92 and the mouth portion 93 by injection molding, and that on the capped applicator 95 side, the tube portion 96, handle 97, and shaft 98 are integrally formed from the same material by injection molding. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 3854824 [Patent Document 2] Patent No. 5325291 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the configuration of Patent Document 2, when the container 90 shown in Fig. 1 is integrally molded by injection molding as shown in Fig. 2(a), one end needs to be open during injection molding because a insert (mold core) Co2 is inserted and pulled out to form a squeezing part 94 below the mouth part 93 (Fig. 3, S81, S83), and the container part (S83) formed by injection molding has a tube shape 91 without a bottom at the lower end so that the container part can be sealed in a later process (S84). In the tube-shaped container parts 91, 92, the lower end is thinner than the other parts, so that the applicator 99 cannot be inserted all the way to hold it.

[0009] Furthermore, as shown in FIG. 2(b), because mold inserts Co4 and Co5 are inserted and removed to form the threads on the inner circumference of tubular portion 96 (FIG. 3, S85, S87), on the capped applicator 95 side, applicator 99 cannot be integrally molded by injection molding (S86) with tubular portion 96, handle 97, and shaft 98, and these are attached later (S89).

[0010] Furthermore, when squeezing portion 94 is formed as a stepless annular wiper from the same resin as the container body, such as hard HDPE (high density polyethylene), as this resin is less elastic than rubber or elastomer, so force is required to insert and remove the applicator, and there is a risk that the applicator 99 will be damaged by the squeezing portion 94, so it is not possible to make the applicator 99 into a fine shape.

[0011] Furthermore, in the configuration of Patent Document 2, the squeezing portion 94 is an annular wiper with no steps, whereas Patent Document 1 proposes a shape in which a step is provided so that the rubber annular wiper is shifted in the radial direction in order to improve the wiping performance of the squeezing portion. Here, if one were to attempt to complicate the shape of the squeezing portion in the container portion by integral injection molding, it would be necessary to form the nest separately, which would complicate the mold.

[0012] In view of the above circumstances, the present invention aims to provide an applicator container having a container and a capped applicator, which reduces the number of parts, allows the applicator to be inserted and held near the bottom end of the container, and does not limit the shape of the applicator by a mold. [Means for solving the problem]

[0013] In order to solve the above problems, the present invention provides An application container having a container and an application tool with a cap, The container has a side wall, a bottom wall closing a lower end of the side wall, a shoulder portion narrowing in diameter from an upper end of the side wall, a cylindrical mouth portion standing from an inner edge portion of the shoulder portion in a direction perpendicular to the bottom wall, and a squeeze portion connected to a lower surface of the shoulder portion and having a portion extending inward beyond the inner edge portion, The capped applicator includes a peripheral wall that engages with the mouth portion, a cover wall that closes an inner peripheral surface of the peripheral wall, a shaft portion having one end attached to a lower surface of the cover wall, and an applicator attached to the other end of the shaft portion, In the container, the squeeze portion, the side wall, the bottom wall, the shoulder portion, and the mouth portion are integrally formed, The capped applicator is configured such that the peripheral wall, the cover wall, the shaft portion, and the applicator are integrally formed, The container and the capped applicator are made of the same resin material. A coating container is provided. Effect of the Invention

[0014] According to one aspect, in an applicator container having a container and a capped applicator, the number of parts can be reduced, the applicator can be inserted and held near the bottom end of the container, and the shape of the applicator is not limited by the mold.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following drawings, the same components are denoted by the same reference numerals, and duplicated explanations may be omitted.

[0017] The present invention relates to an applicator container having a container and a capped applicator, and a method for manufacturing the applicator container. The container is a resin container with a bottom.

[0018] The contents contained in the applicator container of the present invention are liquid cosmetics (for example, eye cosmetic liquids such as mascara) to be applied via an applicator.

[0019] <Overall composition> First, the overall configuration of the application container of the present invention will be described with reference to Figures 4 and 5. Figure 4 is a cross-sectional view of the application container in an engaged state in the first embodiment of the present invention.

[0020] The applicator container 1 according to the present invention includes a container 10 and an applicator 20 with a cap.

[0021] The container 10 is a mascara container (cosmetic container) that is filled (contains) with a liquid cosmetic M, for example, mascara (mascara liquid). The cosmetic M shown in Fig. 4 is not limited to mascara (mascara liquid), but may be a cosmetic for the eyes that can be used for multiple purposes, such as an eyelash growth agent, a mascara base, an eyelash coating agent, a coating agent for eyelash extensions, an eyeliner liquid, and a cosmetic composition that can be used as both a mascara and an eyeliner. Furthermore, by changing the shape of the applicator, the cosmetic may be a liquid cosmetic that is applied via another applicator, such as a lipstick cosmetic, a partial skin cosmetic, or nail polish.

[0022] When the container 10 and the capped applicator 20 are engaged with each other, the applicator 25 attached to the shaft portion 24 is immersed in the cosmetic material M in the container 10.

[0023] FIG. 5 is an exploded cross-sectional view of the applicator container 1 in the first embodiment, disassembled into a container 10 and a capped applicator 20. As shown in FIG.

[0024] With reference to FIGS. 4 and 5, the container 10 has a bottle body 11, a mouth portion 15, and a squeezing portion 16.

[0025] Bottle body (also referred to as bottle portion or storage portion) 11 is a bottomed cylindrical shape having side wall 12 that forms the body portion, bottom wall 13 that closes the lower end of the side wall, and shoulder portion 14 with central hole O1 formed in the center of the upper surface so that applicator 25 can be inserted. Note that, although this example shows an example in which shoulder portion 14 extends horizontally substantially parallel to bottom wall 13, shoulder portion 14 may be inclined away from bottom wall 13 toward central hole O1 as long as it is configured to taper in diameter from the upper end of side wall 12.

[0026] The mouth portion 15 is a cylindrical upright tube portion 151 standing upward (in a direction perpendicular to the bottom wall 13) from the edge (inner edge) IE of the central hole O1 of the shoulder portion 14 of the bottle body 11. A screw projection 152 is formed on the outer periphery of the upright tube portion 151.

[0027] The squeezing portion 16 is a wiping member (wiper portion) that regulates the amount of liquid adhering to the applicator 25 of the capped applicator 20. The squeezing portion 16 is connected to the underside of the shoulder portion 14 and has a portion that extends inward beyond the inner edge portion IE of the shoulder portion 14, which is the inner diameter of the mouth portion 15.

[0028] When capped applicator 20 is removed from container 10, squeezing part 16 comes into contact with applicator 25 to squeeze out excess mascara from applicator 25. This squeezing part 16 makes it possible to appropriately adjust the amount of mascara contained in applicator 25. Details of squeezing part 16 will be described in detail with reference to Figs. 6 to 9.

[0029] In the container 10 of the present invention, the side wall 12, bottom wall 13, shoulder portion 14, and mouth portion 15, including the squeeze portion 16, are integrally formed from the same resin.

[0030] The capped applicator 20 mainly comprises a cap portion 21, a shaft portion 24, and an applicator 25.

[0031] The cap portion 21 is composed of a peripheral wall 22 and a lid wall 23. The peripheral wall 22 is a cylindrical portion that can be engaged with the mouth portion 15 of the container 10, and a screw projection 221 is formed on the inner circumference near the lower end. The screw projection 221 formed on the inner circumferential surface of the peripheral wall 22 below the lid wall 23 can be engaged with the screw projection 152 formed on the outer surface of the mouth portion 15 of the container 10.

[0032] The peripheral wall 22 has a lid wall 23 as a boundary, and the lower side forms an engaging tube 222 that engages with the mouth 15 of the container 10, and the upper side forms an extending tube 223 that does not engage with the container 10 and extends to make it easier for the user to grip when applying makeup.

[0033] The lid wall 23 is connected to the inner periphery of the peripheral wall 22 and seals the container 10. The lid wall 23 serves as a lid portion that closes the upper end of the container 10 to prevent the liquid cosmetic material contained therein from coming into contact with the lid wall 23 and leaking out when the applicator container 1 is turned downward.

[0034] One end of shaft portion 24 is attached to the underside of lid wall 23 of cap portion 21, and applicator 25 is attached to the other end. Shaft portion 24 is provided with bulged portion 26 on the outer periphery side of the peripheral surface, bulging outwardly in a skewer shape in cross section. Other details of the upper end of shaft portion 24 will be described later with reference to Figures 11 and 12.

[0035] Applicator 25 is attached to the other end of shaft 24 and is an application member (also called an applicator or application body) used to apply the impregnated liquid cosmetic (e.g., mascara liquid M) to a target to be applied, such as the user's eyelashes. Details of applicator 25 will be described later with reference to FIG. 13.

[0036] In the capped applicator 20 of the present invention, the peripheral wall 22, the cover wall 23, the shaft portion 24, and the applicator 25, as well as the depending peripheral wall 27, the protrusions 28, and the ring-shaped projections 29 (see Figure 11) described below, are integrally formed from the same resin.

[0037] Furthermore, the container 10 and the capped applicator 20 are made of the same resin material. For example, the container 10 and the capped applicator 20 are preferably made of polyamide (PA), polypropylene (PP), polyester (PET, PBT), styrene (PS, AS, ABS), nitrile (PAN), polycarbonate (PC), polylactic acid (PLA), etc. Among these, polyamide or polypropylene is more preferable.

[0038] (Squeezing portion of container in first embodiment) Next, the squeezing portion of the container of the present invention will be described in detail with reference to Figs.

[0039] Fig. 6 is an explanatory diagram of the squeezing unit in the first embodiment, in which (a) is a cross-sectional view of the squeezing unit, and (b) is an enlarged perspective view of the squeezing unit.

[0040] In the first embodiment, as shown in FIGS. 6(a) and 6(b), the squeezing portion 16 is configured to include four wiping pieces (wiper pieces) 61, 62, 63, and 64 that are divided in the circumferential direction of the mouth portion 15.

[0041] 4 and 6, the wiping pieces 61, 62, 63, and 64 are formed to be thinner than the side wall 12, the bottom wall 13, the shoulder portion 14, and the mouth portion 15. As shown in FIG.

[0042] 6(a), wiping piece 61 has a hanging piece 611, a lower contact piece 612, and an upright contact piece 613. The wiping piece 61 will be described below as an example, but wiping pieces 62, 63, and 64 have the same member configuration as wiping piece 61.

[0043] The hanging piece 611 is located outside the inner edge IE that defines the central hole O1 and hangs down connected to the lower surface of the shoulder portion 14.

[0044] The lower contact piece 612 is tapered from the lower end of the depending piece 611 , and its inner end portion extends inward beyond the inner edge IE, which is the inner diameter of the mouth portion 15 .

[0045] The standing contact piece 613 extends from the inner end of the lower contact piece 612 so as to curve upward and outward in the radial direction of the mouth portion 15. As shown in Fig. 6(b) , the standing contact piece 613 is wider in the circumferential direction of the mouth portion 15 than the hanging piece 611 and the lower contact piece 613. Furthermore, a receiving surface R1 is provided on the upper inner side of the standing contact piece 613.

[0046] 6(b), of the four wiping pieces 61 to 64, the wiping pieces 61 and 63 are shorter in the vertical direction than the wiping pieces 62 and 64 and are positioned on the inside of the overlapping pieces. Therefore, the wiping pieces 61 and 63 are short wiping pieces and the wiping pieces 62 and 64 are long wiping pieces.

[0047] 7A and 7B are diagrams illustrating overlapping of the squeezing parts of the container in the first embodiment. In detail, in Fig. 7, (a) is a top view seen from surface A in Fig. 5, and (b) is a bottom view seen from surface B in Fig. 5.

[0048] The innermost edge R1i of the standing contact piece 613 is arc-shaped with a diameter smaller than the inner diameter of the mouth portion 15.

[0049] The wiping pieces 61 to 64 are arranged in the circumferential direction of the mouth portion 15 such that the short wiping pieces 61, 63 and the long wiping pieces 62, 64 are alternately arranged.

[0050] 6(b) and 7(a), the arc-shaped lower end edges R1i, R3i of the upright contact pieces 613, 633 of the short wiping pieces 61, 63 are located closer to the center in the radial direction of the mouth portion 15 than the arc-shaped lower end edges R2i, R4i of the upright contact pieces 623, 643 of the adjacent long wiping pieces 62, 64 on both sides. In other words, the arc-shaped lower end edges R2i, R4i of the upright contact pieces 623, 643 of the long wiping pieces 62, 64 are located closer to the outside in the radial direction of the mouth portion than the arc-shaped lower end edges R1i, R3i of the upright contact pieces 613, 633 of the adjacent short wiping pieces 61, 63 on both sides. Moreover, the arc-shaped lower end edges R1i to R4i, which form the inner diameter of the squeezing portion, can all be made smaller than the inner diameter of the mouth portion 15.

[0051] The shape of the squeeze portion 16, which overlaps in the radial direction of the mouth portion 15, cannot be formed by injection molding, because the insert cannot be removed even if the mold shown in Fig. 2 is made complex. Therefore, in the present invention, the container 10 is formed by a 3D printer.

[0052] Fig. 8 is an explanatory diagram of a plurality of wiping pieces of the squeezing unit 16 in the first embodiment. Specifically, in Fig. 8, (a) is a cross-sectional view taken along C plane in Fig. 6(b), and (b) is a cross-sectional view taken along D plane in Fig. 6(b).

[0053] Here, comparing Figures 8(a) and 8(b), the upright contact pieces 613, 633 of the short wiping pieces 61, 63 are positioned lower than the upright contact pieces 623, 643 of the long wiping pieces 62, 64 in the extension direction of the side wall 12, i.e., on the side of the bottom wall 13 away from the mouth portion 15.

[0054] More specifically, in the short wiping pieces 61, 63 shown in Figs. 6(a) and 8(b), the lower contact pieces 612, 632 extending in the radial direction are bent at a right angle to the hanging pieces 611, 631, that is, extend substantially horizontally.

[0055] In contrast to this, in the long wiping pieces 62, 64, the lower contact pieces 622, 642 extending in the radial direction are bent at an obtuse angle to the hanging pieces 621, 641, that is, extend at an incline so as to be positioned lower as they approach the radial center.

[0056] With this configuration, when viewed from above as shown in Figure 7(a), the innermost edge R1i, R3i of the short wiping pieces 61, 63 are located more inward than the innermost edge R2i, R4i of the long wiping pieces 62, 64, but when viewed from below as shown in Figure 7(b), the arcs of the edge R1i, R3i of the short wiping pieces 61, 63 and the edge R2i, R4i of the long wiping pieces 62, 64 are located on approximately the same circle.

[0057] In this embodiment, four wiping pieces 61 to 64 are provided as the plurality of wiping pieces. However, the squeezing portion of the first embodiment of the present invention may have an even number of wiping pieces, which may be four or more.

[0058] 9A and 9B are diagrams showing a state in which the squeeze portion 16 in the first embodiment is bent, in which (a) shows the state when the applicator is inserted, and (b) shows the state when the applicator is removed.

[0059] As described above, the wiping pieces 61, 62, 63, 64 constituting the squeezing portion 16 of the present invention are formed to be thinner than the side wall 12, the bottom wall 13, the shoulder portion 14, and the mouth portion 15. As shown in Figures 7(a) and 7(b), the hanging pieces 611-641 which are the root portions of the wiping pieces 61-64 are provided adjacent to each other with a gap in between in the circumferential direction of the mouth portion 15.

[0060] Therefore, when the applicator 25 or expanded portion 26 of the capped applicator 20 comes into contact with the portions of each wiping piece 61-64 of the squeezing part 16 that extend inward beyond the inner diameter (inner peripheral edge IE) of the mouth part 15, the hanging pieces 611-641 which are the base parts of each wiping piece 61-64 bend, and the lower contact pieces 612-642 and the upright contact pieces 613-643 expand radially outward or inward.

[0061] The squeezing portion 16 in this embodiment is not annular, but is divided in the circumferential direction, and the hanging pieces 611-641 which are the root portions are spaced apart from each other, so that even when a small force is applied, only one or more wiping pieces 61-64 located in the direction in which the force is received can bend independently.

[0062] Therefore, by using such a wiping piece that is flexible in the circumferential direction as the squeezing portion 16, when the applicator contacts the wiping piece to adjust the amount of application, the wiping piece side bends precisely, so no burden is placed on the applicator 25 side. Therefore, the applicator side can be made into a fine shape such as hair-like.

[0063] A method for molding the container 10 including the squeeze portion 16 from resin will be described below.

[0064] (Manufacturing method) Next, a manufacturing flow of the application container of the present invention will be described with reference to FIG.

[0065] 10, in step S1, the shape of the container 10 is input to the 3D printer via the information processing device 4. Note that a known 3D printer can be used.

[0066] Then, in step S2, the container 10 is integrally formed from resin using a 3D printer.

[0067] In addition, in step S3, the shape of the capped applicator 20 is input to the 3D printer via the information processing device 4.

[0068] Then, in S4, the capped applicator 20 is integrally formed from resin using a 3D printer.

[0069] In the container molding process S2 in Figure 10, a 3D printer can be used to integrally mold container 10 out of resin, which has a side wall 12, a bottom wall 13 closing the lower end of the side wall, a shoulder portion 14 tapering in diameter from the upper end of side wall 12, a tubular mouth portion 15 rising from the inner edge portion IE of the shoulder in a direction perpendicular to the bottom wall, and a squeezing portion 16 connected to the underside of shoulder portion 14 and having a portion extending inward beyond the inner edge portion IE of mouth portion 15.

[0070] 8, in the container squeezing portion 16 of this embodiment, the short wiping pieces 61, 63 and the long wiping pieces 62, 64 are both shaped to bend inward from the outer hanging piece 611, so that a conductive space S1 toward the central hole O1 is provided upward in the wiping pieces 61 to 64. This space S1 makes it easy to discharge uncured material from below inside the bottle 11 when the container is formed.

[0071] By forming them integrally in this way, the number of parts can be reduced in an application container having a container and a capped applicator. Furthermore, unlike the conventional example, the container has a bottom wall 13, so the applicator can be inserted near the bottom end of the container and held there. In addition, since a 3D printer does not use a mold, the shape of the squeeze part and the applicator is not limited by the mold.

[0072] (Applicator with cap) Next, the engaging shape of the capped applicator will be described with reference to Figures 11 and 15. Figure 11 is an explanatory diagram of the engaging portion of the capped applicator in an embodiment of the present invention. In Figure 11, (a) is an enlarged cross-sectional view of the vicinity of the engaging portion, and (b) is a bottom perspective view of the vicinity of the engaging portion.

[0073] As shown in FIG. 11, the capped applicator 20 is further provided with a hanging peripheral wall 27, a protrusion 28, and a ring-shaped projection 29.

[0074] The depending peripheral wall 27 is a peripheral wall that is outside the shaft portion 24, has a smaller diameter than the peripheral wall 22, and depends downwardly concentrically with the peripheral wall 22 from the underside of the cover wall 23. The mouth portion 15 of the container 10 is capable of being screwed into and engaged with the peripheral wall 22 with the upper end of the mouth portion 15 being sandwiched between the peripheral wall 22 and the depending peripheral wall 27.

[0075] The outer circumferential surface of the depending peripheral wall 27 is provided with a protrusion 28 which is a continuous protrusion that goes around the outer circumferential surface of the depending peripheral wall 27 .

[0076] The ring-shaped projection 29 is an annular projection that projects downward from the lower surface of the cover wall 23 , outboard of the depending peripheral wall 27 and inboard of the peripheral wall 22 , concentrically with the peripheral wall 22 and the depending peripheral wall 27 .

[0077] FIG. 12 is an explanatory diagram of an engagement portion between the container 10 and the capped applicator 20 in the first embodiment of the present invention.

[0078] The outer edge of bulged portion 26 formed on shaft 24 is thick enough to come into contact with and pass through the inner circumferential surface of mouth 15. As a result, when the container is closed, the contents adhering to the inner circumferential surface of mouth 15 of container 10 are scraped off by bulged portion 26 passing through. This makes it possible to reduce adhesion of the contents to shaft 24 the next time the container is opened and applicator 25 is pulled out.

[0079] Furthermore, when the peripheral wall 22 of the cap portion 21 and the mouth portion 15 are engaged with each other, the expanded diameter portion 26 is in contact with the long wiping pieces 62, 64 of the squeezing portion 16. This defines the radial position of the shaft portion 24 in the engaged state.

[0080] The protrusions 28 formed on the outer peripheral surface of the depending peripheral wall 27 function as an airtight member that seals by coming into close contact with the inner peripheral surface of the mouth portion 15 from the inside when the mouth portion 15 and the peripheral wall 22 are threadedly engaged.

[0081] When the screw engagement between the mouth 15 of the container 10 and the peripheral wall 22 of the cap portion 21 reaches its end point, the ring-shaped projection 29 functions as an airtight member that tightly fits the upper end of the mouth 15 to form a seal.

[0082] Capped applicator 20 having such a configuration cannot be produced by injection molding because the presence of bulging portion 26 and ring-shaped protrusion 29 would prevent the nesting of the metal mold from coming out. Therefore, the shape of capped applicator 20 can be produced by forming it with a 3D printer.

[0083] (Configuration of applicator) 13 is an enlarged view of applicator 25 included in the capped applicator of the present invention. As described above, since the squeeze portion can be partially bent, the flexibility of applicator 25 is not limited.

[0084] As shown in FIG. 13, the applicator 25 has a tip region 51, an application region 52, and a rear end region .

[0085] The tip region 51 is a substantially hemispherical member having a tip as an apex, which gradually becomes thicker from the tip toward the application region 52 .

[0086] A plurality of bristle projections 53 are provided to stand radially from the periphery of the application area 52. For example, when applying mascara to eyelashes, each bristle projection 53 combs the eyelashes from the root to the tip while applying the mascara, thereby lifting the eyelashes from the root and curling the entire eyelashes, thereby giving them volume.

[0087] The rear end region 54 is a connection portion with the shaft portion 24 and gradually tapers from the application region 52 toward the shaft 24 .

[0088] Here, the length of the tips of the radial trichomes 53 in the application region 52, i.e., the axial thickness of the application region 52, is approximately equal to the thickness of the rearmost end of the tip region 51 and the frontmost end of the rear region .

[0089] 14 is an explanatory diagram of contact between applicator 25 of the present invention and squeezing part 16. In Fig. 14, (a) shows a state in which rear end region 54 of applicator 25 abuts against squeezing part 16, and (b) shows a state in which application region 52 of applicator 25 abuts against squeezing part 16.

[0090] As shown in Figure 16, the axial thickness at the tip position of the thin hair-like projections 53 of application region 52 is approximately equal to the thickness at the tip-most side of rear end region 54. Therefore, when applicator 25 is removed, rear end region 54 first comes into contact with squeezing portion 16 as shown in Figure 14(a), and then, while maintaining that angle, application region 52 comes into contact with squeezing portion 16 and is pulled up as shown in Figure 14(b).

[0091] Therefore, while passing through application area 52, the angle of wiping piece 61 of squeezing part 16 does not change unless the angle of capped applicator 20 is changed. As a result, when applicator 25 starts to come into contact, a slightly strong force is applied to rear end area 54 in order to bend wiping piece 61 of the squeezing part, but while passing through application area 52, the inclination of wiping piece 61 is maintained, so no strong force is applied to bristle projections 53.

[0092] Therefore, excess mascara liquid on applicator 25 can be squeezed out without damaging trichomes 53 of application area 52. With applicator 25 and squeezing part 16 of this shape, the amount of mascara absorbed in applicator 25 can be appropriately adjusted.

[0093] (Molding of applicator with cap)

[0094] In the 3D printer, resin modeling proceeds in a direction such that the resin region is continuous. As shown in Fig. 11, shaft portion 24 and hanging peripheral wall 27 hang down from the underside of cover wall 23, and the lower end side is located in the space, so that when molding capped applicator 20, molding is performed in order from the upper end peripheral wall 22 side.

[0095] That is, first the upper end peripheral wall 22, the cover wall 23, the ring-shaped projection 29, the hanging peripheral wall 27 with the ridges 28 formed on the outside, and the upper end side of the shaft portion 24 are formed, and then the lower end side of the shaft portion 24, the expanded diameter portion 26, and the applicator 25 are molded in that order.

[0096] Thus, in the applicator formation process of step S4 in Figure 10, a 3D printer can be used to integrally mold capped applicator 20 out of resin, the capped applicator 20 having peripheral wall 22 that engages with mouth portion 15, cover wall 23 that seals the inner surface of peripheral wall 22, shaft portion 24 having one end attached to the underside of cover wall 23, and applicator 25 attached to the other end of shaft portion 24.

[0097] (Squeezing portion of container in second embodiment) Fig. 15 is a cross-sectional view of a container 10A according to a second embodiment of the present invention. As shown in Fig. 15, in the second embodiment, the shape of the squeezing part 17 in the container 10A is different from that in the first embodiment, but the shapes of other parts of the container 10A and the shape of the capped applicator 20 are similar to those in the first embodiment. Details of the squeezing part 17 in this embodiment will be described below with reference to Fig. 16.

[0098] 16A and 16B are explanatory views of a squeezing unit 17 according to a second embodiment of the present invention, in which (a) is an enlarged cross-sectional view of the squeezing unit 17, and (b) is a see-through perspective view of the squeezing unit 17.

[0099] The squeezing unit 17 according to the second embodiment has four legs 71 to 74 and a floating annular wiper 75.

[0100] The four legs 71 to 74 are divided in the circumferential direction of the mouth portion 15 and extend downward from the lower surface of the shoulder portion 14, outside the inner edge IE of the mouth portion 15.

[0101] The floating annular wiper 75 is a floating annular wiper connected to the lower ends of the legs 71-74. The floating annular wiper 75 is shaped like a downward-facing truncated cone in a side view, with the lower end side being smaller than the upper end, and is a truncated cone cylinder (tapered cylinder) with no upper or lower surfaces and only side surfaces. The diameter of the inner peripheral edge 7i on the lower end side of the floating annular wiper 75 is smaller than the inner diameter of the mouth portion 15, and the inner peripheral edge 7i is located inside the inner peripheral edge IE of the mouth portion 15.

[0102] 16(a) and 16(b), in this embodiment, the leg portions 71 to 74 are formed to be thinner than the side wall 12, the bottom wall 13, the shoulder portion 14, and the mouth portion 15. The leg portions 71, 72, 73, and 74 are spaced apart from one another in the circumferential direction of the mouth portion 15.

[0103] Therefore, when a part of the capped applicator 20 comes into contact with the inner edge 7i of the floating annular wiper 75, which is located inside the inner edge IE of the mouth portion 15, each of the multiple legs 71-74 that is located in the direction in which the force is applied bends, and the floating annular wiper 75 tilts according to the direction of contact.

[0104] This reduces the burden on the applicator 25 during squeezing.

[0105] 16(a), the legs 71-74 of the squeeze unit 17 are disposed from the outer side of the inner peripheral edge IE of the mouth 15 so as to avoid the central hole O1, and therefore a conductive space S2 is provided in the vicinity of the mouth 15. This space S2 makes it easy to discharge uncured material from inside the bottle 11 when the container 10A is formed by a 3D printer.

[0106] The container of this embodiment is also integrally formed by a 3D printer, reducing the number of parts and allowing the applicator to be inserted near the bottom end of the container. Furthermore, since no mold is used, the shapes of the squeeze part and the applicator are not limited by the mold.

[0107] Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to such specific embodiments, and various modifications and changes are possible within the scope of the gist of the embodiments of the present invention described in the claims.
