Modes for Carrying Out the Invention

[0014] Hereinafter, referring to the drawings, the coating container 100 according to the first embodiment of the present disclosure will be described in detail. In this specification, claims, abstract, and drawings, the vertical direction is based on the state where the coating container 100 is upright on a horizontal plane as shown in FIG. 1. The upper part of the coating container 100 means the upper part in FIG. 1, and the lower part of the coating container 100 means the lower part in FIG. 1. Therefore, for example, even when the coating container 100 is in a tilted posture where the coating part 30 is located below the container body 10, the coating part 30 side is upward. The radial direction is a direction along a straight line passing through the central axis O extending in the vertical direction of the container body 10 and perpendicular to the central axis O. The inner side in the radial direction means the direction approaching the central axis O along the straight line, and the outer side in the radial direction means the direction moving away from the central axis O along the straight line. The circumferential direction is the rotational direction around the central axis O.

[0015] As shown in FIG. 1, the coating container 100 includes a container body 10 that stores the content liquid, a mounting cap 20 mounted on the mouth portion 11 of the container body 10, a coating portion 30 (impregnated body) that covers the discharge hole 24d provided in the mounting cap 20 from above and applies the content liquid to the coating target by containing the content liquid discharged from the discharge hole 24d, a piercing portion 51a (engaging portion) fixed to the mounting cap 20 and fixing the coating portion 30 to the mounting cap 2 with the coating portion 30 engaged from the outer side in the radial direction, and a rotating ring 40 that surrounds the piercing portion 51a from the outer side in the radial direction and displaces the piercing portion 51a in the radial direction by rotation around the central axis O.

[0016] The container body 10 includes a cylindrical mouth portion 11 provided at the upper part, a substantially cylindrical body portion 13 connected to the lower end portion of the mouth portion 11, and a bottom portion 15 that closes the lower end portion of the body portion 13. The inside of the body portion 13 forms a storage space S for the content liquid. On the outer peripheral surface of the mouth portion 11, a male screw portion 11a that can be screwed and engaged with a female screw portion 21a provided on the inner surface of the peripheral wall 21 of the mounting cap 20 is provided.

[0017] The container body 10 can be formed, for example, by extrusion blow molding of a parison made of a synthetic resin material. The materials used to constitute the container body 10 include, for example, low-density polyethylene (LDPE), high-density polyethylene resin (HDPE), polypropylene (PP), or polyethylene terephthalate (PET). However, the invention is not limited to this embodiment, and other molding methods such as biaxial stretch blow molding or injection molding may be employed. The container body 10 may have a single-layer structure or a laminated structure having multiple resin layers.

[0018] The mounting cap 20 is attached to the mouth 11 of the container body 10. As shown in Figure 2, the mounting cap 20 comprises a peripheral wall 21 attached to the mouth 11 of the container body 10, a top wall 22 that closes the upper end of the peripheral wall 21, a sealing cylinder 22a that hangs down from the lower surface of the top wall 22 on the radially inner side of the peripheral wall 21, a mounting cylinder 22c that is erected on the upper surface of the top wall 22 and to which the movable part base 52 (base) is attached, and a discharge part 24 provided at the radial center position of the top wall 22.

[0019] A packing 26 is attached to the outer surface of the sealing cylinder 22a to provide a liquid-tight seal to the opening 11. As shown in Figure 2, the packing 26 is sandwiched between the upper end surface of the opening 11 and the lower surface of the top wall 22.

[0020] As shown in Figure 2, the discharge section 24 includes a discharge cylinder 24a erected on the upper surface of the top wall 22, a valve seat 24b that slopes radially inward upward from the upper end of the discharge cylinder 24a, and a valve fixing cylinder 24c that hangs down from the lower end of the discharge cylinder 24a. A closure valve 60, which will be described later, is fixed to the valve fixing cylinder 24c, and the discharge hole 24d can be opened and closed by the closure valve 60.

[0021] The closure valve 60 comprises a closure valve body 61 that closes the discharge hole 24d by contacting a valve seat 24b provided on the discharge section 24, a valve body biasing spring 62 integrally formed with the lower end of the closure valve body 61 and functioning as a compression spring to bias the closure valve body 61 upward, and a cylindrical valve body base 63 integrally formed with the lower end of the valve body biasing spring 62 and fixing the closure valve 60 to the mounting cap 20. As shown in Figure 2, the radial center of the closure valve body 61 protrudes upward and contacts or is close to the central recess 32 of the coating section 30. The valve body base 63 has a base locking projection 63b at its upper end and a base fixing flange 63a at its lower end, and the closure valve 60 is fixed to the mounting cap 20 by engaging these with the valve fixing cylinder 24c.

[0022] The coating section 30 is formed as an impregnating body that impregnates the liquid contents contained within the container body 10. The coating section 30 impregnates the contents when applying the liquid contents to the object to be coated. The coating section 30 comprises an elastically deformable porous member and a mesh body that is permeable to liquid and covers the porous member from above and radially outward. The coating section 30 may also be composed only of the porous member. The porous member is, for example, a foamed (sponge) of synthetic resin such as urethane or polyethylene having a large number of micropores. In plan view, the coating section 30 is formed in a substantially circular shape centered on the central axis O. The upper surface of the coating section 30 is formed in a dome-shaped convex curved surface with the center bulging upward. The lower surface of the coating section 30 has a central recess 32 where the discharge section 24 is located, with the radial center recessed upward. An annular recess 34 is formed on the radial outer edge of the lower part of the coating section 30, where the rotating ring 40 and movable part assembly 50, which will be described later, are located.

[0023] The coating portion 30 is configured to be difficult to move radially relative to the mounting cap 20 by engaging with a locking projection 22b that is provided on the upper surface of the top wall 22 and has a tapered shape that tapers upward. The coating portion 30 is also restrained and fixed in the vertical direction by a piercing portion 51a (engaging portion), which will be described later, piercing the side surface of the coating portion 30 from the radially outer side. Furthermore, as shown in Figures 2 and 3, the coating portion 30 is fixed to the mounting cap 20 with its radially outer surface at the bottom positioned radially by a positioning projection 22d.

[0024] When the center of the upper surface of the coating section 30 is pressed downward, it pushes down the closing valve body 61 against the biasing force of the valve body biasing spring 62 of the closing valve 60, creating a gap between the closing valve body 61 and the valve seat 24b, thereby opening the discharge hole 24d. As a result, the inside and outside of the container body 10 are connected, and the contents contained in the container body 10 can be supplied from the coating section 30 to the object to be coated through the discharge hole 24d.

[0025] The piercing portion 51a (engaging portion) is provided as part of the movable part assembly 50. As shown in Figures 2 and 3, the movable part assembly 50 comprises a movable part 51 having the piercing portion 51a, and a movable part base 52 (base) connected to the movable part 51 via a bent portion 51c and having a substantially arc shape in plan view.

[0026] As shown in Figure 3, the movable part 51 is rotatable around the bent part 51c in a plan view, and a tapered projection 51a is provided at the end opposite to the bent part 51c in the circumferential direction. The projection 51a is oriented radially inward, approximately perpendicular to the longitudinal direction of the movable part 51. As the movable part 51 rotates in the horizontal plane around the bent part 51c, the projection 51a can be displaced radially. In addition, a pressing contact part 51b that protrudes radially outward is provided on the radially outer side of the projection 51a, slightly closer to the bent part 51c. As will be described later, when the pressing projection 41a of the rotating ring 40 comes into contact with the pressing contact part 51b, the projection 51a is displaced radially inward and pierces the coating part 30. This allows the coating part 30 to be fixed to the mounting cap 20 in the circumferential and vertical directions. Furthermore, near the bent portion 51c of the movable portion 51, there is a movable portion locking portion 51d that protrudes radially outward and restricts the circumferential movement of the rotating ring 40, which will be described later.

[0027] As shown in Figure 3, the movable part base 52 is a part that has an arc shape in plan view and is provided at four locations in the circumferential direction. As shown in Figure 2, the movable part base 52 is attached to the mounting cap 20 by undercut engagement with the radially outer surface of the mounting cylinder 22c which is erected on the mounting cap 20. In this embodiment, the movable part base 52 is also fixed to the mounting cylinder 22c in the circumferential direction by vertical ribs (not shown). Positioning protrusions 22d for positioning the radial position of the coating part 30 protrude radially inward from the radially inner surface of the mounting cylinder 22c. Three positioning protrusions 22d are provided at circumferential positions corresponding to each movable part base 52.

[0028] As shown in Figure 3, the base of the movable part 52 is provided with a bent portion 51c that is formed to be radially thinner at the clockwise end in the circumferential direction in a plan view. The movable part 51 is connected to the base of the movable part 52 via the bent portion 51c.

[0029] Furthermore, as shown in Figure 3, a first rotation stopper 52c and a second rotation stopper 52d are provided on the radially outer surface of the movable part base 52 to restrain the rotation range of the rotating ring 40, which will be described later, in the circumferential direction. The first rotation stopper 52c is located approximately in the center of the circumferential direction of the movable part base 52 in a plan view, and the second rotation stopper 52d is located at the counterclockwise end in the circumferential direction of the movable part base 52.

[0030] In a plan view, a rotating ring 40 is provided on the radially outer side of the movable assembly 50. The rotating ring 40 includes a gripping ring 41 that the user grips when rotating the rotating ring 40 around the central axis O, and a sliding ring 43 that is integrally formed radially inward of the gripping ring 41 and slides circumferentially relative to the movable assembly 50.

[0031] Furthermore, the radially inner surface of the gripping ring 41 of the rotating ring 40 is provided with a pressing projection 41a that protrudes radially inward. As shown in Figure 3, when the gripping ring 41 is rotated clockwise in a plan view until the pressing projection 41a contacts the second rotation stopper 52d, the pressing projection 41a contacts the pressing contact portion 51b provided on the radially outer side of the piercing portion 51a of the movable portion 51, pressing and displacing the movable portion 51 radially inward.

[0032] In addition to the pressing projection 41a, the rotating ring 40 is provided with a ring-side stopper 41b that restricts the circumferential movement of the rotating ring 40. When the rotating ring 40 is rotated counterclockwise in a plan view, as shown in Figure 5, the pressing projection 41a releases the radially inward pressure on the pressing contact portion 51b before the ring-side stopper 41b contacts the first rotation stopper 52c, and the pressing projection 41a contacts the movable part locking portion 51d, returning the movable part 51 to its original position during molding. In other words, the movable part locking portion 51d acts as an auxiliary rib that returns the movable part 51 to its original position. As a result, the bent portion 51c is restored to the shape of the movable part assembly 50 during molding, and the piercing portion 51a moves to a state where it is not piercing the coating portion 30 (see Figures 4 and 5). At this time, the movable part 51 is positioned within the movable part recess 52b provided in the movable part base 52, as shown in Figures 5 and 6.

[0033] In the state shown in Figures 4 and 5, where the piercing portion 51a is not piercing the coating portion 30, the user can remove the coating portion 30 from the coating container 100 by separating it upward from the mounting cap 20. With this configuration, even if the coating portion 30 becomes severely soiled after prolonged use of the coating container 100, the user can easily replace only the coating portion 30 with a new one by removing it from the coating container 100. Furthermore, if the coating portion 30 is not severely soiled and can be reused after cleaning, only the coating portion 30 can be easily cleaned by separating it from the coating container 100.

[0034] After replacing or cleaning the coating unit 30, the coating unit 30 is placed on the top wall 22 again with the annular recess 34 radially positioned by the inner surface of the positioning projection 22d. Next, the rotating ring 40 is rotated clockwise in a plan view from the state in which the pressing projection 41a shown in Figures 4 and 5 abuts against the movable part locking part 51d to the state in which the pressing projection 41a abuts against the second rotation stopper 52d shown in Figures 2 and 3. This causes the pressing projection 41a to press the pressing contact part 51b of the movable part 51 radially inward again. As a result, the movable part 51 rotates around the bent part 51c and moves radially inward, and the piercing part 51a pierces the coating unit 30 again from the radial outside. Therefore, the coating unit 30 is fixed to the mounting cap 20 again.

[0035] When using the coating container 100 configured in this way, the user grasps the body portion 13 of the container body 10 with one hand and lifts it, starting from the state in which the coating portion 30 shown in Figures 1 to 3 is engaged and fixed with the piercing portion 51a, and rotates it so that the coating portion 30 is positioned below the body portion 13 to tilt it. Next, the user increases the pressure in the housing space S of the container body 10 by pressing the body portion 13 radially inward, and presses the upper surface of the coating portion 30 against the object to be coated SF, as shown in Figure 7. By pressing the coating portion 30 against the upper surface of the object to be coated SF, the reaction force from the object to be coated SF pushes down the upper end of the closure valve body 61, which was protruding upward from the discharge portion 24, against the biasing force of the valve body biasing spring 62. As a result, as shown in Figure 7, the closure valve body 61 separates from the valve seat 24b, and the liquid contents, under positive pressure, pass through the gap between the discharge hole 24d and the valve biasing spring 62, and are further supplied into the coating section 30 through the gap between the closure valve body 61 and the valve seat 24b. However, the method of discharge is not limited to the above method; the liquid contents may also be discharged from the discharge hole 24d by the weight of the liquid contents due to the application container 100 being tilted, without the user having to press on the body 13.

[0036] The liquid contents supplied to the coating section 30 after passing through the closure valve 60 become impregnated into the coating section 30, which is an impregnating body. The user can then apply the contents impregnated in the coating section 30 to the target SF by pressing the coating section 30 against the target SF.

[0037] As described above, this embodiment comprises a container body 10 for containing the liquid contents, a mounting cap 20 attached to the mouth 11 of the container body 10, a coating part 30 that covers the discharge hole 24d provided in the mounting cap 20 from above and applies the liquid contents, an engaging part that fixes the coating part 30 to the mounting cap 20 by engaging with the coating part 30 from the radially outside, and a rotating ring 40 that surrounds the engaging part from the radially outside and displaces the engaging part radially by rotation around the central axis O. With this configuration, even if the coating container 100 is used for a long time and the coating part 30 becomes heavily soiled, the user can easily rotate the rotating ring 40 to switch from the state shown in Figures 2 and 3, etc., where the engaging part engages with the coating part 30 and the coating part 30 is fixed to the mounting cap 20, to the state shown in Figures 4 and 5, etc., where the engaging part does not engage with the coating part 30. Therefore, users can easily remove only the coating part 30 from the coating container 100 and replace it with a new coating part 30. Furthermore, if the coating part 30 is not severely soiled and can be reused after cleaning, only the coating part 30 can be separated from the coating container 100, easily cleaned, and then reattached for use.

[0038] Furthermore, in this embodiment, the engaging portion is configured to have a tapered, piercing portion 51a that is directed radially inward when engaged with the coating portion 30. By adopting this configuration, the tapered, piercing portion 51a, which is the engaging portion, can be easily engaged with and fixed to the coating portion 30 with little force.

[0039] Furthermore, in this embodiment, the piercing portion 51a is provided on a movable portion 51 that is connected to a base portion (movable portion base portion 52) fixed to the mounting cap 20 via a bent portion 51c and rotates around the bent portion 51c to be displaced radially. The rotating ring 40 is configured to have a pressing projection 41a that presses the movable portion 51 radially inward by rotating around the central axis O. By adopting such a configuration, the rotational movement of the rotating ring 40 can be converted into a radial movement of the piercing portion 51a with a simple configuration, making it possible to easily fix and release the coating portion 30.

[0040] Furthermore, in this embodiment, the discharge hole 24d is configured to be open and closed by a closure valve 60 biased upward by an elastic member (valve biasing spring 62). By adopting this configuration, the discharge hole 24d can be opened and the liquid contents can be applied by a simple operation of pressing the application part 30 against the object to be applied SF, and unintended discharge of the liquid contents when the application part 30 is not being pressed can be suppressed. In addition, since the discharge hole 24d can be closed by biasing force even when the inside of the container body 10 is not pressurized, liquid leakage during distribution and storage can be suppressed.

[0041] Next, the coating container 200 according to the second embodiment of this disclosure will be described with reference to Figures 8 to 11. Note that this embodiment is similar to the configuration of the first embodiment, except for some differences in the configuration of the mounting cap 120, the rotating ring 140, and the piercing portion 151a. Therefore, the differences from the first embodiment will be explained in detail.

[0042] The mounting cap 120 is attached to the mouth 11 of the container body 10. As shown in Figure 8, the mounting cap 120 comprises a peripheral wall 21 attached to the mouth 11 of the container body 10, a top wall 22 that closes the upper end of the peripheral wall 21, a sealing cylinder 22a that hangs down from the lower surface of the top wall 22 on the radially inner side of the peripheral wall 21, a mounting cylinder 125 erected on the upper surface of the top wall 22 and to which the rotating ring 140 is attached, and a discharge part 24 provided at the radial center position of the top wall 22.

[0043] On the radially inner surface of the mounting cylinder 125, positioning protrusions 122d protrude radially inward to position the radial position of the coating portion 30. Three positioning protrusions 122d are provided at circumferential positions corresponding to each mounting cylinder 125.

[0044] In this embodiment, the piercing portion 151a (engaging portion) that fixes the coating portion 30 is integrally formed with the rotating ring 140. The rotating ring 140 is equipped with a gripping ring 141 that the user grips when rotating the rotating ring 140 around the central axis O, and the movable portion 151 is integrally formed with the gripping ring 141 via a bent portion 151c on the radially inner side of the gripping ring 141. In other words, in this embodiment, although the movable portion 151 is integrally formed with the rotating ring 140, it is a separate part from the rotating ring 140. The piercing portion 151a is provided on the side of the movable portion 151 opposite to the bent portion 151c in the longitudinal direction. In the example of Figure 9, the piercing portion 151a is bent to the left from the bent portion 151c of the movable portion 151 toward the longitudinal tip in a plan view, and has a tapered shape.

[0045] Furthermore, the rotating ring 140 is provided with a ring-side stopper 141b that protrudes radially inward from the gripping ring 141 and restricts the rotation range of the rotating ring 140, and an engaging rib 141c that slides while engaging with the engaging projection 125c on the mounting cap 20 side. When the rotating ring 140 is rotated clockwise in a plan view from the state shown in Figure 9, where the ring-side stopper 141b is in contact with the fourth rotation stopper 125b on the mounting cylinder 125 side, until the ring-side stopper 141b comes into contact with the third rotation stopper 125a that protrudes radially outward from the clockwise end of the mounting cylinder 125, the movable part 151 rotates clockwise around the bent part 151c, as shown in Figure 11, and its bent part side end comes into contact with the counterclockwise end in the circumferential direction of the mounting cylinder 125 in a plan view. The contact of the circumferential end of the mounting cylinder 125 causes the movable part 151 to rotate clockwise around the bent part 151c, and the piercing part 151a that was inserted into the coating part 30 is pulled out of the coating part 30 (Figures 10 and 11).

[0046] In the state shown in Figures 10 and 11, where the piercing portion 151a is not piercing the coating portion 30, the user can remove the coating portion 30 from the coating container 200 by separating it upward from the mounting cap 120. With this configuration, even if the coating portion 30 becomes severely soiled after prolonged use of the coating container 200, the user can easily remove only the coating portion 30 from the coating container 200 and replace it with a new one. Furthermore, if the coating portion 30 is not severely soiled and can be reused after cleaning, only the coating portion 30 can be separated from the coating container 200, easily cleaned, and then reattached for reuse.

[0047] After replacing the coating section 30 or after cleaning the coating section 30, the coating section 30 is placed on the top wall 22 again with the annular recess 34 positioned radially by the inner surface of the positioning projection 122d. Next, the rotating ring 140 is rotated counterclockwise in a plan view from the state in which the ring-side stopper 141b shown in Figures 10 and 11 is in contact with the third rotation stopper 125a to the state in which the ring-side stopper 141b is in contact with the fourth rotation stopper 125b shown in Figures 8 and 9. The clockwise end of the mounting cylinder 125 presses the movable part 151 from the circumferential direction, causing the movable part 151 to rotate counterclockwise around the bent part 151c. As a result, the piercing part 151a pierces the coating section 30 again from the radial outside, and the coating section 30 is fixed to the mounting cap 120 again.

[0048] As described above, in this embodiment, the piercing portion 151a is provided on a movable portion 151 connected to the rotating ring 140 via a bent portion 151c. The rotation of the rotating ring 140 around its central axis O causes the movable portion 151 to contact a portion (mounting cylinder 125) erected on the mounting cap 120 and rotate around the bent portion 151c, thereby displacing the piercing portion 151a radially. By adopting this configuration, the rotational motion of the rotating ring 140 can be converted into radial motion of the piercing portion 151a with a simple configuration, making it possible to easily fix and release the coating portion 30.

[0049] While this disclosure has been described based on various drawings and embodiments, it should be noted that those skilled in the art will find it easy to make various modifications and alterations based on this disclosure. Therefore, it should be noted that these modifications and alterations are included within the scope of the present invention. For example, the functions included in each component can be rearranged in a logically consistent manner, and multiple components can be combined into one or separated. It should be understood that these are also included within the scope of the present invention.

[0050] For example, in the first embodiment, the engagement between the puncture portion 51a and the coating portion 30 is released by rotating the rotating ring 40 counterclockwise in a plan view, and in the second embodiment, the engagement between the puncture portion 151a and the coating portion 30 is released by rotating the rotating ring 40 clockwise in a plan view, but the invention is not limited to these embodiments. The engagement between the puncture portions 51a, 151a and the coating portion 30 may also be released by rotating them in opposite directions.

[0051] Furthermore, although needle-shaped punctures 51a and 151a were used as the engaging portion in the first and second embodiments, the invention is not limited to this embodiment, and other forms of engaging portions having an uneven shape that increases the coefficient of friction with the coating portion 30 may be used.

[0052] Furthermore, in the first and second embodiments, a resin compression spring was used as the valve biasing spring 62, but the system is not limited to this configuration, and other forms of elastic members, such as leaf springs, may be used. [Industrial applicability]
