Description

Technical Field

[0001] The present invention relates to an application container.

Background Art

[0002] Conventionally, as an application container for measuring and applying contents, for example, as disclosed in Patent Document 1 below, an application container includes: a bottomed cylindrical container body that accommodates contents; an inner plug member attached to a mouth portion of the container body and formed with a communication hole communicating with the inside of the container body; a measuring cylinder member that forms a measuring chamber between the inner plug member and the inner plug member, the measuring chamber communicating with the inside of the container body through the communication hole, and is formed with a discharge hole communicating with the measuring chamber; and an application plug provided in the measuring chamber, a tip end of which protrudes outside the measuring chamber from the discharge hole, which is known.

[0003] The application plug is disposed so as to be movable in a container axial direction between a measuring position where the communication between the discharge hole and the measuring chamber is blocked and communication between the measuring chamber and the communication hole is allowed, and an application position that is located closer to a bottom side of the container body than the measuring position, blocks communication between the measuring chamber and the communication hole, and allows communication between the discharge hole and the measuring chamber.

[0004] When applying the contents to a portion to be coated in the above application container, the posture of the application container is changed in a state where the application plug is located at the measuring position to allow the contents to flow into the measuring chamber. Subsequently, the tip end of the application plug is pressed against the portion to be coated to move the application plug to the application position. This makes it possible to apply the measured content to the portion to be coated while pressing the tip end of the application plug against the portion to be coated.

Summary of the Invention

Problem to be Solved by the Invention

[0006] Incidentally, with the aforementioned conventional coating containers, there is a need to alleviate the irritation caused when pressing the tip of the coating stopper and to ensure that the coating operation is being performed correctly.

[0007] The present invention has been made in view of these circumstances, and its purpose is to provide an application container that allows the user to feel that the application operation is being performed reliably while mitigating the irritation when the tip of the application stopper is pressed. [Means for solving the problem]

[0008] (1) The coating container according to the present invention comprises: a bottomed cylindrical container body containing the contents to be coated; an inner stopper member attached to the mouth of the container body and having a communication hole formed therein that communicates with the inside of the container body; a measuring cylinder member between itself and the inner stopper member, forming a measuring chamber that communicates with the inside of the container body through the communication hole, and having a discharge hole formed at its upper end that communicates with the measuring chamber; a coating plug provided inside the measuring cylinder member, with its tip protruding from the discharge hole to the outside of the measuring cylinder member; and a guide member provided outside the measuring cylinder member and pressed against the part to be coated together with the tip of the coating plug, wherein the coating plug blocks communication between the discharge hole and the measuring chamber, and the measuring chamber and the communication hole The guide member is provided so as to be movable in the container axial direction between a measuring position that connects the two, and a coating position located below the measuring position that blocks communication between the measuring chamber and the communication hole, and connects the discharge hole and the measuring chamber. The guide member comprises a contact ring located above the coating stopper located at the coating position, a mounting ring located below the contact ring and mounted on the outside of the measuring cylinder member, and a plurality of elastic pieces that intermittently connect the mounting ring and the contact ring in the circumferential direction around the container axis and support the contact ring so as to be elastically displaceable downward. The plurality of elastic pieces are curved so as to bulge radially outward in a longitudinal cross-sectional view along the container axis, intersecting the container axis.

[0009] According to the coating container of the present invention, when the tip of the coating stopper is pressed against the area to be coated, the contact ring of the guide member attached to the outside of the measuring cylinder member is pressed against the area to be coated. The contact ring is supported by multiple elastic pieces so as to be elastically displaceable, and the reaction force due to the elastic deformation of the multiple elastic pieces generates appropriate resistance, giving the user a reliable feeling of application. As a result, the user can accurately recognize the application position and adjust the application position. In addition, since the contact ring is pressed against the area to be coated in addition to the tip of the coating stopper, the contact area with the area to be coated is increased, and the irritation when pressing the tip of the coating stopper can be reduced. Furthermore, since the multiple elastic pieces are curved so as to bulge radially outward in a longitudinal cross-sectional view along the container axis, bending deformation that would crush the contact ring is less likely to occur when the contact ring is elastically displaced. As a result, for example, the multiple elastic pieces can prevent hair or other objects from getting caught.

[0010] (2) The tip of the coating plug may be positioned inside the contact ring.

[0011] In this case, the tip of the coating plug is positioned inside the contact ring, so that the contact ring and the tip of the coating plug do not face each other in the axial direction of the container. This prevents hair or other objects from getting caught between the contact ring and the tip of the coating plug when the contact ring elastically displaces downward when the tip of the coating plug is pressed against it. [Effects of the Invention]

[0012] According to the coating container of the present invention, it is possible to reduce the irritation when pressing the tip of the coating stopper while still being able to feel that the coating operation is being performed reliably. [Brief explanation of the drawing]

[0013] [Figure 1] This is a longitudinal cross-sectional view showing the main part of a coating container according to one embodiment of the present invention. [Figure 2] This figure shows the coating container in Figure 1 with the coating stopper raised to the metering position. [Figure 3]This is a plan view of a guide member according to one embodiment of the present invention. [Figure 4] This is a semi-longitudinal cross-sectional view of a guide member according to one embodiment of the present invention. [Figure 5] This figure shows the state in which the contents are being applied to the area to be coated in the coating container shown in Figure 1. [Modes for carrying out the invention]

[0014] The following describes an application container according to one embodiment of the present invention, with reference to Figure 1. The application container 1 contains contents such as hair growth agents or medicinal liquids that are applied to a part of the human body to be applied, such as the scalp or skin 100 (see Figure 5, which will be described later).

[0015] The coating container 1 comprises a bottomed cylindrical container body 2 in which the contents are contained; an inner stopper member 3 attached to the mouth 2a of the container body 2 and having a communication hole 3a that communicates with the inside of the container body 2; a measuring cylinder member 4 between itself and the inner stopper member 3, forming a measuring chamber 4a that communicates with the inside of the container body 2 through the communication hole 3a, and having a discharge hole 4b at its tip that communicates with the measuring chamber 4a; a coating stopper 5 provided inside the measuring cylinder member 4, with its tip 5a protruding from the discharge hole 4b to the outside of the measuring cylinder member 4; and a guide member 6 provided outside the measuring cylinder member 4 and pressed against the part to be coated 100 together with the tip 5a of the coating stopper 5. Furthermore, the coating container 1 is equipped with a cap member 7 that covers the mouth 2a of the container body 2, the inner stopper member 3, the measuring cylinder member 4, the coating stopper 5, and the guide member 6 from the outside.

[0016] Here, the mouth portion 2a of the container body 2, the inner stopper member 3, the measuring cylinder member 4, the coating stopper 5, the guide member 6, and the cap member 7 each have their central axes aligned on a common axis. Hereafter, this common axis will be referred to as the container axis O, the bottom side of the container body 2 along the container axis direction (the lower side in Figure 1) will be referred to as the lower side, and the mouth portion 2a side of the container body 2 along the container axis direction (the upper side in Figure 1) will be referred to as the upper side. When viewed from the container axis direction, the direction intersecting the container axis O will be referred to as the radial direction, and the direction revolving around the container axis O will be referred to as the circumferential direction.

[0017] The mouth portion 2a is formed to have a smaller diameter than the shoulder portion, body portion, and bottom portion of the container body 2 that are continuous with the mouth portion 2a. An external thread portion is formed on the outer peripheral surface of the mouth portion 2a. The external thread portion may be, for example, a double thread. The outer diameter of the upper end portion of the mouth portion 2a is smaller than the outer diameter of a portion of the mouth portion 2a located below the upper end portion. An annular or arc-shaped projection that protrudes radially outward and extends in the circumferential direction is formed on the outer peripheral surface of the upper end portion of the mouth portion 2a. A rotation-preventing rib 2b protruding radially outward is formed at the lower end portion of the mouth portion 2a.

[0018] The inner plug member 3 includes a cylinder barrel 10, a support body 11, a main fitting cylinder 12, an outer fitting cylinder 13, and a connecting flange 14. The cylinder barrel 10, the support body 11, the main fitting cylinder 12, the outer fitting cylinder 13, and the connecting flange 14 are arranged coaxially with the container axis O and are integrally formed.

[0019] The cylinder barrel 10 is formed in a bottomed cylindrical shape and is provided inside the mouth portion 2a of the container body 2. A plurality of communication holes 3a are formed in the cylinder barrel 10 at intervals in the circumferential direction. The interior of the cylinder barrel 10 communicates with the interior of the container body 2 through the plurality of communication holes 3a. The communication holes 3a are integrally formed across the peripheral wall and the bottom wall of the cylinder barrel 10. Note that the number of the communication hole 3a may be one. The lower end portion of the application plug 5 is in close contact with a portion of the inner peripheral surface of the peripheral wall of the cylinder barrel 10 located above the communication holes 3a so as to be detachable upward.

[0020] The support body 11 is arranged radially inward of the plurality of communication holes 3a. The support body 11 protrudes upward from the central portion of the bottom wall of the cylinder barrel 10. The support body 11 is formed in a solid rod shape. The upper end portion of the support body 11 protrudes upward beyond the cylinder barrel 10 and the main fitting cylinder 12.

[0021] The main fitting cylinder 12 surrounds the cylinder tube 10 from the radially outer side and is fitted into the mouth portion 2a. The inner peripheral surface of the main fitting cylinder 12 is connected to the upper end of the cylinder tube 10 via a connecting flange 14. The connecting flange 14 is formed in an annular shape extending in the radial direction. The upper part of the main fitting cylinder 12 protrudes upward from the mouth portion 2a. The lower part of the main fitting cylinder 12 protrudes downward beyond the connecting flange 14.

[0022] The outer fitting cylinder 13 surrounds the upper part of the main fitting cylinder 12 from the radially outer side. The lower end of the outer fitting cylinder 13 is connected to the outer peripheral surface of the main fitting cylinder 12. The lower end surface of the outer fitting cylinder 13 is placed on the upper opening edge of the mouth portion 2a. On the outer peripheral surface of the outer fitting cylinder 13, an annular or arc-shaped protrusion that protrudes radially outward and extends in the circumferential direction is formed.

[0023] The measuring cylinder member 4 includes: a mounting cylinder portion 20 mounted on the mouth portion 2a of the container body 2; a discharge cylinder 21 positioned above the mounting cylinder portion 20 and having a discharge hole 4b inside thereof; and a connecting cylinder portion 22 connecting the mounting cylinder portion 20 and the discharge cylinder 21. In the illustrated example, the diameter of the measuring cylinder member 4 is reduced stepwise upward in the order of the mounting cylinder portion 20, the connecting cylinder portion 22, and the discharge cylinder 21.

[0024] The mounting cylinder portion 20 is formed in a capped cylindrical shape having an annular top wall and a peripheral wall. The peripheral wall of the mounting cylinder portion 20 is externally fitted to the upper end of the mouth portion 2a and the outer fitting cylinder 13 of the inner plug member 3. On the inner peripheral surface of the peripheral wall of the mounting cylinder portion 20, two annular or arc-shaped protrusions that protrude radially inward and extend in the circumferential direction are formed with an interval in the container axial direction. Among these two protrusions, the lower protrusion is undercut-fitted to the protrusion of the mouth portion 2a, and the upper protrusion is undercut-fitted to the protrusion of the outer fitting cylinder 13.

[0025] The lower surface of the top wall of the mounting cylinder portion 20 abuts against the upper opening edge of the outer fitting cylinder 13. A cylindrical body 24 is formed on the top wall of the mounting cylinder portion 20, projecting downwards and inserted between the outer fitting cylinder 13 and the upper part of the main fitting cylinder 12. The cylindrical body 24 projects downwards from the inner peripheral edge of the top wall of the mounting cylinder portion 20. This cylindrical body abuts against at least one of the main fitting cylinder 12 and the outer fitting cylinder 13, ensuring a seal at the connection point between the stopper member 3 and the measuring cylinder member 4 in the measuring chamber 4a.

[0026] The connecting cylinder portion 22 is formed in a topped cylindrical shape having an annular top wall and a circumferential wall. The circumferential wall of the connecting cylinder portion 22 extends upward from the inner peripheral edge of the top wall of the mounting cylinder portion 20. The top wall of the connecting cylinder portion 22 is formed in a dome shape, with the inner and outer diameters decreasing as it goes upward. In this embodiment, the space defined by the connecting cylinder portion 22 of the measuring cylinder member 4 and the main fitting cylinder 12 and connecting flange 14 of the plug member 3 constitutes the measuring chamber 4a.

[0027] The discharge cylinder 21 is formed in a cylindrical shape that forms the discharge hole 4b and protrudes upward from the inner peripheral edge of the top wall of the connecting cylinder portion 22. The discharge cylinder 21 may also be formed in a rectangular shape, for example. Alternatively, the discharge cylinder 21 may be omitted, and the inside of the annular top wall of the connecting cylinder portion 22 may serve as the discharge hole 4b. In other words, the upper end of the measuring cylinder member 4 may be the top wall of the connecting cylinder portion 22.

[0028] The coating stopper 5 is provided so as to be movable in the axial direction of the container between a metering position (see Figure 2) in which communication between the discharge hole 4b and the metering chamber 4a is blocked and communication between the metering chamber 4a and the communication hole 3a, and a coating position (see Figure 1 and Figure 5 described later) which is located below the metering position and blocks communication between the metering chamber 4a and the communication hole 3a, while communication between the discharge hole 4b and the metering chamber 4a. Hereinafter, the description will focus on the state in which the coating stopper 5 is located in the coating position unless otherwise specified.

[0029] The coating stopper 5 comprises a guide tube 30, a sealing tube 31, and a tip tube 32. The guide tube 30, the sealing tube 31, and the tip tube 32 are arranged coaxially with the container axis O and are integrally formed.

[0030] The guide tube 30 is provided inside the measuring tube member 4 and is formed in a top-shaped tube. The guide tube 30 is externally fitted onto the support 11 of the inner stopper member 3 so as to be vertically movable. The lower end opening edge of the guide tube 30 abuts against a rib or step formed at the base of the support 11, thereby restricting further downward movement. Alternatively, the upper end of the support 11 may be brought into contact with the top wall of the guide tube 30 to restrict the downward movement of the coating stopper 5.

[0031] The seal cylinder 31 is positioned radially outward of the guide cylinder 30. The upper ends of the seal cylinder 31 and the guide cylinder 30 are connected to the bottom wall of the bottomed cylindrical tip cylinder 32. The seal cylinder 31 extends downward from the bottom wall of the tip cylinder 32. The lower end of the seal cylinder 31 is in close contact with the inner circumferential surface of the cylinder cylinder 10 and is detachable above the inner circumferential surface of the cylinder cylinder 10. The thickness of the lower end of the seal cylinder 31 is thinner than the thickness of the other parts.

[0032] A seal step portion 31a is formed on the outer circumferential surface of the intermediate portion of the seal cylinder 31 in the container axial direction. The seal step portion 31a is formed in an annular shape that extends continuously along the circumferential direction of the seal cylinder 31. As shown in Figure 2, when the coating plug 5 is in the metering position, the seal step portion 31a abuts from below against the peripheral edge of the opening of the discharge hole 4b inside the metering cylinder member 4.

[0033] The sealing step 31a abuts from below against the opening edge of the discharge hole 4b inside the measuring cylinder member 4, so that even if an external force acts to move the coating plug 5 upward relative to the measuring chamber 4a, the coating plug 5 is prevented from moving any further upward. In the illustrated example, the sealing step 31a abuts against the inner edge of the lower surface of the top wall of the connecting cylinder portion 22 when the coating plug 5 is in the measuring position.

[0034] Furthermore, when the coating plug 5 is in the metering position, the upper part of the seal cylinder 31 fits into the discharge hole 4b, and the seal step portion 31a abuts against the peripheral edge of the opening of the discharge hole 4b inside the metering cylinder member 4 from below, thereby blocking communication between the discharge hole 4b and the metering chamber 4a. At this time, the lower end of the seal cylinder 31 detaches upward from inside the cylinder cylinder 10, thereby opening the metering chamber 4a and the communication hole 3a into communication.

[0035] The tip cylinder 32 has approximately the same outer diameter as the upper part of the guide cylinder 30. The upper end of the tip cylinder 32 (the tip 5a of the coating plug 5) is located above the upper opening edge of the discharge cylinder 21. As shown in Figure 1, a vertical groove 32a is formed on the outer circumferential surface of the tip cylinder 32, which connects the metering chamber 4a and the discharge hole 4b when the coating plug 5 is in the coating position. The vertical groove 32a extends linearly in the direction of the container axis and is formed in multiple locations on the outer circumferential surface of the tip cylinder 32 at intervals.

[0036] A projection 32b is formed on the bottom wall of the tip cylinder 32, which is inserted radially inward into the engaging piece 52, described later, provided on the cap member 7. The upper end of the projection 32b is located below the upper end of the tip cylinder 32. An annular or arc-shaped engaging projection 32c is formed on the inner circumferential surface of the upper end of the tip cylinder 32, which protrudes radially inward and extends circumferentially.

[0037] The cap member 7 is detachably attached to the opening 2a of the container body 2. The cap member 7 is formed in a top-top cylindrical shape having a cap top wall 40 and a cap peripheral wall 41. The cap peripheral wall 41 has approximately the same outer diameter as the body of the container body 2. A cap mounting cylinder 42 is provided radially inside the cap peripheral wall 41. The cap mounting cylinder 42 is suspended downward from the lower surface of the cap top wall 40.

[0038] The inner circumferential surface of the lower end of the cap mounting cylinder 42 has a female threaded portion that can be screwed onto the male threaded portion of the mouth 2a of the container body 2. The female threaded portion may be, for example, a double-start thread. In addition, a stepped portion with a circumferentially facing wall surface is formed at the lower end of the cap mounting cylinder 42, and is capable of contacting the anti-rotation rib 2b of the container body 2 in the circumferential direction. Note that the cap member 7 is not limited to being screwed onto the mouth 2a in a detachable manner, but may also be fitted onto the mouth 2a in a detachable manner using an undercut fitting.

[0039] A lifting cylinder 43 is provided radially inside the cap mounting cylinder 42. The lifting cylinder 43 is suspended downward from the lower surface of the cap top wall 40. An annular or arc-shaped groove extending in the circumferential direction is formed on the inner circumferential surface of the lower end of the lifting cylinder 43. A lifting member 50 is fitted into this groove of the lifting cylinder 43.

[0040] The lifting member 50 is formed in a top-shaped cylindrical form having a top wall and a circumferential wall. A protrusion 51 is formed on the outer circumferential surface of the circumferential wall of the lifting member 50, which undercuts into a groove formed on the inner circumferential surface of the lifting cylinder 43. The circumferential wall of the lifting member 50 is fitted onto the discharge cylinder 21 when the cap member 7 is attached.

[0041] An engaging piece 52 is provided on the radially inner side of the peripheral wall of the lifting member 50. The engaging piece 52 is suspended downward from the lower surface of the top wall of the lifting member 50. The engaging piece 52 is formed in a cylindrical or arc shape that extends in the circumferential direction and is inserted radially into the inner side of the tip cylinder 32 of the coating plug 5. The outer circumferential surface of the engaging piece 52 has a projection that engages in the container axial direction with the engaging projection 32c formed on the inner circumferential surface of the tip cylinder 32. Therefore, when the cap member 7 is removed, the coating plug 5 is lifted up and moves from the coating position shown in Figure 1 to the measuring position shown in Figure 2.

[0042] The guide member 6 is mounted on the outside of the measuring cylinder member 4. The guide member 6 includes a contact ring 60 that is pressed against the part to be coated 100 together with the tip 5a of the coating plug 5, a mounting ring 61 that is located below the contact ring 60 and is mounted on the outside of the measuring cylinder member 4, and a plurality of elastic pieces 62 that intermittently connect the mounting ring 61 and the contact ring 60 in the circumferential direction around the container axis O and support the contact ring 60 so that it can be elastically displaced downward.

[0043] The contact ring 60, the mounting ring 61, and the multiple elastic pieces 62 are integrally molded by resin molding or the like. Note that all or part of the components of the contact ring 60 may be separate parts. As shown in the plan view of Figure 3, the contact ring 60 is formed in an annular shape centered on the container axis O. Inside the contact ring 60, as shown in Figures 1 and 2, the tip 5a of the coating plug 5 is positioned with a radial gap. The inner diameter of the contact ring 60 is larger than the tip 5a of the coating plug 5, and slightly larger than the outermost diameter of the connecting cylinder portion 22 of the measuring cylinder member 4.

[0044] As shown in Figure 1, the contact ring 60 is positioned above the tip 5a of the coating plug 5 at the coating position. Therefore, the contact ring 60 contacts the area to be coated 100 before the tip 5a of the coating plug 5 at the coating position (when the downward movement of the coating plug 5 is restricted). Note that, as shown in Figure 2, the contact ring 60 is positioned below the tip 5a of the coating plug 5 at the metering position.

[0045] As shown in Figure 3, the mounting ring 61 is formed in an annular shape that is coaxial with the contact ring 60 and slightly larger than the contact ring 60. The elastic piece 62 is formed in a strip shape with a constant circumferential dimension and connects the contact ring 60 and the mounting ring 61. The elastic piece 62 is provided intermittently in the circumferential direction. In this embodiment, a total of eight elastic pieces 62 are provided at 45-degree intervals around the container axis O. The spacing and number of elastic pieces 62 are not particularly limited. A space S is formed between adjacent elastic pieces 62 in the circumferential direction, connecting the inside and outside of the guide member 6.

[0046] As shown in Figure 4, thick-walled portions 61A and thin-walled portions 61B are alternately formed on the inner circumferential surface of the mounting ring 61 in the circumferential direction. A mounting groove 61a is formed on the inner circumferential surface of the lower end of the thick-walled portion 61A, recessed radially outward. The mounting groove 61a extends in the circumferential direction. The thin-walled portion 61B has the same outer diameter as the thick-walled portion 61A, but its inner diameter is larger than that of the thick-walled portion 61A, and its radial thickness is relatively smaller than that of the thick-walled portion 61A. The thin-walled portion 61B is formed at a position corresponding to the elastic piece 62.

[0047] As shown in Figure 1, the mounting ring 61 is fitted onto the mounting cylinder portion 20 of the measuring cylinder member 4. The outer circumferential surface of the mounting cylinder portion 20 has an annular or arc-shaped fitting projection 20a that protrudes radially outward and extends circumferentially. The fitting projection 20a is fitted into the mounting groove 61a of the mounting ring 61.

[0048] As shown in Figures 1 and 2, the multiple elastic pieces 62 are curved so as to bulge radially outward in a longitudinal cross-sectional view along the container axis O, intersecting the container axis O. Specifically, as shown in Figure 4, the elastic piece 62 comprises a first portion 62a extending upward from the upper end of the mounting ring 61, and a second portion 62b extending upward from the upper end of the first portion 62a and curving radially inward. The first portion 62a is a straight portion extending in the direction of the container axis. The second portion 62b is continuous with the first portion 62a and is a curved portion that bends radially inward with a predetermined curvature in a longitudinal cross-sectional view along the container axis O.

[0049] The operation of the coating container 1 of this embodiment will be described below.

[0050] As shown in Figure 1, before use of the coating container 1, the lower end of the sealing cylinder 31 of the coating stopper 5 is in close contact with the inner circumferential surface of the cylinder cylinder 10 of the inner stopper member 3, thereby blocking communication between the measuring chamber 4a and the communication hole 3a.

[0051] To apply the contents of the container body 2 to the area to be coated 100, first, the cap member 7 is removed, exposing the tip 5a of the coating stopper 5 to the outside. When the cap member 7 is detached upward, the engaging piece 52 of the lifting member 50 and the engaging projection 32c of the tip cylinder 32 engage with each other in the axial direction of the container, causing the coating stopper 5 to be lifted and move to the measuring position as shown in Figure 2.

[0052] Furthermore, since the male thread portion of the mouth 2a and the female thread portion of the cap member 7 are double-start threads, the thread lead is larger compared to a single-start thread configuration. This allows for a larger displacement in the container axial direction relative to the circumferential rotation of the cap member 7. As a result, the coating stopper 5 can be moved upward quickly, and the cap member 7 can be quickly detached from the mouth 2a of the container body 2.

[0053] As shown in Figure 2, when the coating plug 5 moves to the metering position, the upper part of the seal cylinder 31 fits into the discharge hole 4b, and the seal step portion 31a abuts against the peripheral edge of the opening of the discharge hole 4b inside the metering cylinder member 4 from below, thereby blocking communication between the discharge hole 4b and the metering chamber 4a. At this time, the lower end of the seal cylinder 31 detaches upward from inside the cylinder cylinder 10, thereby opening the metering chamber 4a and the communication hole 3a into communication.

[0054] Next, by inverting the coating container 1 or pointing the tip 5a of the coating stopper 5 diagonally downward, the contents of the container body 2 are allowed to flow into the measuring chamber 4a through the communication hole 3a. Then, as shown in Figure 5, when the tip 5a of the coating stopper 5 is pressed against the area to be coated 100, the coating stopper 5 moves toward the coating position. During this process, the contact ring 60 of the guide member 6, which is attached to the outside of the measuring cylinder member 4, is pressed against the area to be coated 100.

[0055] The contact ring 60 is supported by multiple elastic pieces 62 so as to be elastically displaceable, and the reaction force from the elastic deformation of the multiple elastic pieces 62 generates appropriate resistance, giving the user a reliable feel during application. In addition, when the contact ring 60 is pressed against the area to be applied 100 in addition to the tip 5a of the application stopper 5, the contact area with the area to be applied 100 is increased, which can alleviate the discomfort when the tip 5a of the application stopper 5 is pressed against the area. Furthermore, in a longitudinal cross-sectional view along the container axis O, the multiple elastic pieces 62 are curved so as to bulge radially outward intersecting the container axis O, making it difficult for the contact ring 60 to be crushed or bent when it is elastically displaced. This prevents, for example, the multiple elastic pieces 62 from getting caught in hair or other objects.

[0056] Then, when the coating plug 5 moves to the coating position, the sealing step portion 31a detaches downward from the opening periphery of the discharge hole 4b inside the measuring cylinder member 4, and the lower end of the sealing cylinder 31 is inserted inside the peripheral wall of the cylinder cylinder 10 and comes into close contact with the inner surface of the peripheral wall. As a result, communication between the measuring chamber 4a and the communication hole 3a is blocked, and the vertical groove 32a of the coating plug 5 allows communication between the discharge hole 4b and the measuring chamber 4a, so that a certain amount of contents in the measuring chamber 4a passes through the vertical groove 32a and the discharge hole 4b and is coated onto the part to be coated 100.

[0057] Furthermore, even when the coating operation is performed several times by swinging the tip 5a of the coating plug 5 downwards while the coating plug 5 is in the coating position (with downward movement restricted), a guide member 6 with multiple strip-shaped elastic pieces 62 is attached to the outside of the measuring cylinder member 4. Therefore, the user first presses the contact ring 60 against the area to be coated 100, and then pushes in to bring the tip 5a of the coating plug 5 into contact with the area to be coated 100.

[0058] In this process, the user can grasp the application position by pressing the guide member 6, and adjust the application position of the contents. Furthermore, when the user presses the guide member 6, the elastic deformation of the elastic piece 62 creates appropriate resistance, providing a tactile application sensation. Without the guide member 6, when the application container 1 is swung down, the tip 5a of the application stopper 5 (with downward movement restricted) is forcefully pressed against the area to be applied 100, resulting in a very strong irritation. On the other hand, by attaching the guide member 6, this force is mitigated, and the user can be assured that the application operation is being performed correctly.

[0059] Furthermore, since the guide member 6 has no sliding parts or small gaps, it is possible to prevent hair or other objects from getting caught when the guide member 6 is pushed in. In particular, since the multiple elastic pieces 62 are curved so as to bulge radially outward in a longitudinal cross-sectional view along the container axis O, sufficient rigidity is ensured so that bending deformation that would crush the multiple elastic pieces 62 occurs. In addition, since the tip 5a of the coating plug 5 is positioned inside the contact ring 60, the contact ring 60 and the tip 5a of the coating plug 5 do not face each other in the direction of the container axis, and it is possible to prevent hair or other objects from getting caught between the contact ring 60 and the tip 5a of the coating plug 5 when the contact ring 60 is elastically displaced downward when the tip 5a of the coating plug 5 is pressed against it.

[0060] As described above, the coating container 1 according to this embodiment comprises a bottomed cylindrical container body 2 that contains the contents to be applied to the part to be coated 100, an inner stopper member 3 attached to the mouth 2a of the container body 2 and having a communication hole 3a that communicates with the inside of the container body 2, a measuring cylinder member 4 between itself and the inner stopper member 3, having a measuring chamber 4a that communicates with the inside of the container body 2 through the communication hole 3a and having a discharge hole 4b that communicates with the measuring chamber 4a at its upper end, a coating plug 5 provided inside the measuring cylinder member 4 with its tip 5a protruding from the discharge hole 4b to the outside of the measuring cylinder member 4, and a guide member 6 provided outside the measuring cylinder member 4 and pressed against the part to be coated 100 together with the tip 5a of the coating plug 5, wherein the coating plug 5 blocks communication between the discharge hole 4b and the measuring chamber 4a, and The guide member 6 is provided to be movable in the container axial direction between a measuring position that connects the measuring chamber 4a and the communication hole 3a, and a coating position that is located below the measuring position, blocks the communication between the measuring chamber 4a and the communication hole 3a, and connects the discharge hole 4b and the measuring chamber 4a. The guide member 6 includes a contact ring 60 located above the coating plug 5 at the coating position, a mounting ring 61 located below the contact ring 60 and mounted on the outside of the measuring cylinder member 4, and a plurality of elastic pieces 62 that intermittently connect the mounting ring 61 and the contact ring 60 in the circumferential direction around the container axis O and support the contact ring 60 so as to be elastically displaceable downward. In a vertical cross-sectional view along the container axis O, the plurality of elastic pieces 62 are curved so as to bulge radially outward in the direction intersecting the container axis O. With this configuration, it is possible to reduce the irritation when pressing the tip 5a of the coating plug 5 while obtaining a sense that the coating operation is being carried out reliably.
