Abstract
Description
[Technical field]
[0001] The present invention relates to an application container with a rubbing part (such as a brush, a paint brush, or a sponge). [Background technology]
[0002] A known type of container has a brush member attached around a plug member fitted into the mouth and neck of a container, and the plug member has an inner plug placed inside a plug body which has an opening for a pouring outlet in the centre of the top wall, a valve plate interposed between the inner plug and the pouring outlet in an upwardly biased state, a contact which is exposed to the outside from the centre of the valve plate through the pouring outlet is raised, and when the container is inverted, the contact is pressed against the external surface to be coated, causing the liquid inside the container to pass between the plug body and the inner plug and flow out from the pouring outlet (Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication 2016-50017 Summary of the Invention [Problem to be solved by the invention]
[0004] The container in Patent Document 1 closes the valve by pressing the valve plate upward against the top wall of the plug body around the spout, so there was a risk of liquid spraying out due to an increase in internal pressure during distribution or storage of the product.
[0005] An object of the present invention is to provide an application container with a rubbing portion which has improved sealing properties during distribution and storage. [Means for solving the problem]
[0006] The first means includes a container body 2 having a mouth and neck portion 6 standing upright, a first cap 10 attached to the mouth / neck portion 6 and having a first top wall 14 with a liquid passage hole 16 opening therein; a second cap 40 which is attached to the first cap 10 so as to be movable up and down, and which has an application tube portion 60 standing upright from a second top wall 42 opposite the first top wall 14 and communicating with the liquid passage port 16, and which has a valve seat surface portion 64 formed on the inside of the application tube portion 60; A rubbing portion 66 disposed on the upper side of the second top wall 42; a valve member 70 that is disposed inside the application tube portion 60 and has a valve body 72 that is in close contact with the valve seat surface portion 64 in an upwardly biased state so as to be able to rise and fall, and a contact 84 that is erected from the valve body 72 and is for contacting an external surface T to be applied that is higher than the application tube portion 60; In the application container with a rubbing portion, a seal valve V consisting of the valve seat surface portion 64 and the valve body 72 is configured to open and close by the advancement and retreat of the contact 84 relative to the application tube portion 60, A pillar portion 24 is provided protruding from the first top wall 14 toward the inside of the application tube portion 60, and the valve body 72 is configured to be sandwiched between the valve seat surface portion 64 and the pillar portion 24 when the second cap 40 is in the lowermost position.
[0007] In this method, as shown in FIG. 1(A), a first cap 10 having a first top wall 14 opening a liquid passage hole 16 is attached to the mouth and neck portion 6 of the container body 2, and a second cap 40 having a second top wall 42 on which an applicator tube portion 60 communicating with the liquid passage hole 16 is attached to the first cap 10 so as to be freely raised and lowered. Further, a seal valve V is formed by closely contacting a valve body 72 with a valve seat surface portion 64 formed inside the application tube portion 60 . A pillar portion 24 is provided protruding from the first top wall 14 toward the inside of the application tube portion 60, and the valve body 72 is configured to be sandwiched between the valve seat surface portion 64 and the pillar portion 24 when the second cap 40 is in the lowermost position. This structure can improve the sealing condition during distribution and storage.
[0008] The second means has the first means, and the second cap 40 has a linking portion 50 suspended from the second top wall 42, and the first cap 10 has a linking receiving portion 30 connected to the first top wall 14 and facing the linking portion 50 when viewed in a horizontal direction, The linking portion is configured to be engaged with the link receiving portion in a state in which the valve body is sandwiched between the valve seat surface portion and the column portion.
[0009] In this means, as shown in FIG. 1(A), the second cap 40 has a linking portion 50 suspended from the second top wall 42, and the first cap 10 has a linking receiving portion 30 connected to the first top wall 14 and facing the linking portion 50 when viewed horizontally. The linking portion is configured to be engaged with the linking receiving portion in a state in which the valve body is sandwiched between the valve seat surface portion and the column portion. According to this structure, the engaging force of the linking portion 50 against the linking receiving portion 30 can properly maintain the valve body 72 sandwiched between the valve seat surface portion 64 and the column portion 24, thereby ensuring improved sealing performance during transportation and storage.
[0010] The third means includes the second means and is provided with an elastic spring 80 for urging the valve body 72 upward and a support seat S for supporting the elastic spring 80 from below. A valve body pressing portion 28 for pressing the underside i of the valve body 72 is formed at the tip of the column portion 24, and when the second cap 40 rises relative to the first cap 10, the valve seat surface portion 64 and the valve body 72 are separated from each other, and the contactor 84 is pressed against the surface T to be coated, so that the underside i of the valve body 72 can abut against the valve body pressing portion 28.
[0011] As shown in FIG. 1(A), this means is provided with an elastic spring 80 for biasing the valve body 72 upward, and a support seat S for supporting the elastic spring 80 from below. Further, a valve body pressing portion 28 for pressing the lower surface i of the valve body 72 is formed at the tip of the column portion 24 . Then, as shown in FIG. 3, when the second cap 40 rises relative to the first cap 10, the valve seat surface portion 64 and the valve body 72 are separated from each other. In this state, by abutting the contact 84 against the surface T to be coated, it is possible for the lower surface i of the valve body 72 to abut against the valve body holding portion 28. According to this structure, by limiting the range in which the elastic spring 80 is compressed and deformed, it is possible to prevent the compression width n relative to the length m of the elastic spring 80 before compression from becoming excessively large, thereby reducing the deformation strain (n / m) and reducing the sagging (elastic fatigue) of the elastic spring 80.
[0012] The fourth means includes the third means, and the support seat S is disposed at the lower part of the support tube part 58 that is extended downward from the application tube part 60, The application tube portion 60 and the support tube portion 58 form an enclosing tube 56 that is inserted through the second top wall 42 to enclose the column portion 24. The elastic spring 80 is disposed through a gap e between the pillar portion 24 and the surrounding cylinder 56 , from the inside of the support cylinder portion 58 to the inside of the application cylinder portion 60 .
[0013] In this embodiment, as shown in FIG. 1(A), the support seat S is disposed at the lower part of a support tube part 58 which is extended downward from the application tube part 60. The application tube portion 60 and the support tube portion 58 form an enclosing tube 56 that penetrates the second top wall 42 so as to enclose the column portion 24 . The elastic spring 80 is disposed through a gap e between the pillar portion 24 and the surrounding cylinder 56 , from the inside of the support cylinder portion 58 to the inside of the application cylinder portion 60 . According to this structure, the length m of the elastic spring 80 before compression can be made longer compared to a case where a support seat is arranged at the lower end of the application tube part 60, for example, without providing the support tube part 58. Therefore, deformation and strain of the elastic spring 80 can be reduced, and settling (elastic fatigue) of the elastic spring 80 can be reduced. Effect of the Invention
[0014] According to the present invention, it is possible to improve the sealing performance of an application container with a rubbing portion during distribution and storage. [Brief description of the drawings]
[0015] [Figure 1] 1 shows the configuration of an application container with a rubbing part according to an embodiment of the present invention, in which FIG. 1A is a cross-sectional view seen from the side, and FIG. 1B is a plan view illustrating the application container with an overcap omitted. [Diagram 2] FIG. 2 is an enlarged view of a main part of the configuration shown in FIG. [Diagram 3] 4 is an explanatory diagram of a preparation stage for application work using the container shown in FIG. 1, illustrating the stage where the second cap is screwed up onto the first cap. FIG. [Figure 4] FIG. 2 is an explanatory view of a stage in which the contents are applied using the container shown in FIG. BEST MODE FOR CARRYING OUT THEINVENTION
[0016] 1 to 4 show an application container with a rubbing portion according to an embodiment of the present invention. This container is composed of a container body 2, a first cap 10, a second cap 40, a rubbing portion 66, a valve member 70, and an overcap 90. Each of these members can be made of, for example, a synthetic resin material.
[0017] In this embodiment, the container body 2 has a mouth and neck part 6 standing up from a body part 3 via a shoulder part 4. However, this structure can be appropriately changed, and for example, the shoulder part 4 can be omitted. In the illustrated example, the shoulder portion 4 is provided with a rotation-preventing rib 5 for engaging with an engagement protrusion 19 described below. The engagement protrusion 19 and the rotation-preventing rib 5 form a rotation-preventing means C for preventing the first cap 10 from rotating relative to the container body 2. Further, a male thread portion 8 is provided on the outer surface of the mouth / neck portion 6 .
[0018] The first cap 10 is an inner cap attached to the mouth and neck portion 6, and in this embodiment, it is composed of a first top wall 14 having a liquid passage port 16 opened therein and connected to the upper end of a cylindrical attachment tube 12 fitted onto the outer surface of the mouth and neck portion 6, and a pillar portion 24 erected from the center of this first top wall 14. In the illustrated example, the mounting cylinder 12 is provided with a female thread portion 13 which meshes with the male thread portion 8 .
[0019] In the illustrated example, the first top wall 14 is formed by a high wall portion 14a extending radially inward and outward from the upper end of the mounting tube 12, a stepped tube portion 14b suspended from the inner circumferential end of the high wall portion 14a, and a low wall portion 14c connected laterally inward from the lower end of the stepped tube portion 14b. A cylindrical first cap peripheral wall 18 extends vertically from the outer circumferential end of the higher wall portion 14a to the vicinity of the shoulder portion 4. The first cap peripheral wall 18 has an inner surface on which the engaging protrusion 19 described above is provided. However, these structures can be modified as appropriate. For example, the high wall portion 14a may be provided so as to protrude only radially inward from the upper end of the mounting tube 12, and the first cap peripheral wall 18 may be omitted. In this case, the engaging protrusion 19 may be provided at the lower end of the mounting tube 12. An auxiliary tube part 20 is suspended from the lower surface of the higher wall part 14a in close proximity to the inner surface of the mouth-neck part 6. A packing P is disposed on the outside of the auxiliary tube part 20 and is inserted between the mouth-neck part 6 and the higher wall part 14a. The auxiliary tube part 20 may be fitted liquid-tightly to the inner surface of the mouth-neck part 6 as a sealing means for the mouth-neck part 6. In this embodiment, the stepped cylinder portion 14b serves as a bearing cylinder into which a shaft cylinder (slide cylinder portion 44) described below is fitted so as to be movable up and down and rotatable, and is formed in a cylindrical shape. A liquid passage port 16 is formed in the lower wall portion 14c.
[0020] In this embodiment, a link receiving portion 30 for receiving a link portion 50 (described later) is provided upright from an appropriate position of the high wall portion 14a. The link receiving portion 30 in the illustrated example is formed as a cylindrical link receiving tube that stands from the entire periphery of the first top wall 14. In this embodiment, a receiving groove 34 is formed on the outer surface of the linking receiving tube 30, which enables the second cap 40 to be displaced between an upper limit position and a lower limit position by operating the second cap 40 relative to the first cap 10. The receiving grooves 34 in this embodiment are slide grooves in which the locking protrusions 52 of the linking portion 50 described below can slide. These slide grooves are arranged in a plurality of spaced apart portions (opposing portions in the illustrated example) 32 equiangularly spaced apart in the circumferential direction of the linking receiving tube 30, and are formed to have the same shape and rotational symmetry with each other. Specifically, although not shown, each receiving groove 34 is formed of a lower horizontal end portion and a higher horizontal end portion arranged on both sides in the circumferential direction, and an oblique intermediate portion connecting these two ends. The locking projection 52 is formed so that it can move between the lower horizontal end portion and the higher horizontal end portion through this intermediate portion. Although not shown in the figure, a protrusion that the locking protrusion 52 can overcome is provided between the horizontal end and the intermediate portion to prevent the locking protrusion 52 from accidentally moving from the higher horizontal end to the lower horizontal end.
[0021] The pillar portion 24 has a role of pressing a lower surface i of a valve body 72 described below, and a role of sandwiching the valve body 72 between itself and a valve seat surface portion 64 described below. The pillar portion 24 is a pillar-shaped body protruding from the first top wall 14 into the enclosing cylinder 56 described below, and includes both a hollow structure and a solid structure, as described below. The pillar portion 24 has a valve body pressing portion 28 at its tip side for pressing the lower surface i of the valve body 72. In this configuration, when the second cap 40 is raised relative to the first cap 10 (see FIG. 3), and the contact 84 is pressed against the surface T to be coated for coating operation from a state in which the valve seat surface portion 64 and the valve body 72 are separated, the lower surface i of the valve body 72 abuts against the valve body pressing portion 28. This prevents the elastic spring 80, which will be described later, from being excessively elastically compressed and from being elastically fatigued. The upper surface j of the valve body holding portion 28 is formed into a shape corresponding to the lower surface i of the valve body 72 (in the illustrated example, a curved surface that bulges gently upward) as shown in Figure 3, and is formed so that the valve body 72 can be stably placed on the valve body holding portion 28. In this embodiment, the column portion 24 is formed in a cylindrical shape, although the shape can be modified as appropriate. The column portion 24 in the illustrated example has a hollow structure, and is formed by attaching a column top portion 28, which is the valve body holding portion, to the upper end of a column tube portion 26 that stands up from the inner peripheral end of the lower bottom wall 14c. However, this structure can be modified as appropriate and may be formed into a solid rod shape.
[0022] The second cap 40 is attached to the first cap 10 so as to be movable up and down, and has a second top wall 42 opposed to the first top wall 14 . In this embodiment, the second cap 40 is attached to the first cap 10 by closely fitting a slide cylinder portion 44 extending vertically from the second top wall 42 into the inner surface of the stepped cylinder portion 14b so as to be movable up and down. A rectangular second cap peripheral wall 54 extends vertically from the outer circumferential end of the second top wall 42, and an enclosing cylinder 56 surrounding the pillar portion 24 is provided in the center of the second top wall 42. In this embodiment, the slide tube portion 44 is formed as a cylindrical shaft tube rotatably fitted to the inner surface of the stepped tube portion 14b. In the illustrated example, the second cap peripheral wall 54 is formed in a rectangular tube shape as shown in FIG. 1(B), and the outer surface of the second cap peripheral wall 54 is formed with knurls 55 in the form of vertical ribs.
[0023] The surrounding cylinder 56 is composed of a support cylinder part 58 suspended from the second top wall 42 and an application cylinder part 60 erected from the second top wall 42. The surrounding cylinder 56 is in communication with the liquid passage port 16. In the illustrated example, the support tube 58 is suspended from the lower end of the application tube 60 . A bearing seat S for supporting a valve member 70 (described later) from below is formed in a lower portion (the lower end portion in the illustrated example) of the cylindrical bearing portion 58. In the illustrated example, an engagement rib 59 for engaging the valve member 70 is provided on the inner surface of the lower end portion of the cylindrical bearing portion 58 to serve as the bearing seat S. By designing the support seat S to be positioned at the bottom of the support tube portion 58, the length m of the elastic spring before compression can be made longer compared to, for example, a case in which the support seat is provided at the lower end of the application tube portion 60 without providing the support tube portion 58. The application tube portion 60 has an outlet 62 at its upper end. Further, on the inner surface of the application tube portion 60, a valve seat surface portion 64 is formed for abutting against a valve body 72 described later. In the illustrated example, the application tube portion 60 has a large diameter base portion 60a, a small diameter tip portion 60c extending upward through a tapered middle portion 60b having a small diameter at its upper end. The inner surface of the middle portion 60b is formed into the valve seat surface portion 64. As shown in FIG. 2, the tip portion 60c is adjacent to a contact 84, which will be described later, with a small gap g therebetween. During the application operation shown in Figure 4, when the contact 84 is retracted inward in the axial direction of the application tube portion 60, the circumferential groove 86 described below formed around the contact 84 moves to a position facing the tip portion 60c, thereby expanding the flow path area between the tip portion 60c and the contact 84.
[0024] In this embodiment, a linking portion 50 for linking the second cap 40 to the first cap 10 so that the second cap 40 can move up and down and rotate freely relative to the first cap 10 is vertically provided from the second top wall 42. However, this structure can be modified as appropriate, and the second cap 40 may be structured so that it moves up and down without rotating relative to the first cap 10. In the illustrated example, the second top wall 42 is formed with an annular raised portion 46 arranged concentrically with the rotation center O of the second cap 40 shown in Fig. 1(B) when viewed from above. The annular raised portion 46 in the illustrated example has a sideways U-shape in cross section when viewed from the side, as shown in Fig. 2. In the illustrated example, the annular raised portion 46 is arranged slightly radially inward from the second cap peripheral wall 54 when viewed from above, and a pressure contact rib 53 is provided around the outer surface of the annular raised portion 46 for pressure contact with a gripping peripheral wall 94 of an overcap 90 described below. A cylindrical wall (connecting cylinder portion) that is concentric with the center of rotation O is vertically extended from the upper wall portion 48 of the annular raised portion 46 as the connecting portion 50 . The linking portion 50 is provided with a locking projection 52 slidably fitted into the receiving groove 34 so that the second cap 40 can be displaced between a lower limit position and an upper limit position relative to the first cap 10. The main role of the linking portion 50 is to set the lower limit position and the upper limit position, in other words, to set the vertical width of the second cap 40. This vertical width is designed so that an elastic spring 80 described below is not excessively fatigued when a contact 84 described below is lowered (retracted toward the base 60a side of the application tube portion 60) as shown by an imaginary line in Fig. 3 from a state in which the second cap 40 is at the upper limit position as shown in the same figure. The function of the locking projection 52 is to hold the second cap 40 in the lowest position unless the user performs an operation to open the second cap 40 (a screw-up operation in the illustrated example). This ensures that the valve body 72 described below is sandwiched between the column portion 24 and the valve seat surface portion 64. Although not shown, the linking cylinder portion and the linking receiving cylinder may be screwed together by using a normal screw mechanism instead of the locking projection 52 and the receiving groove 34.
[0025] The rubbing portion 66 is disposed on the upper side of the second top wall 42. In this embodiment, the rubbing portion 66 is formed integrally with the second cap 40, but it may be assembled as a separate body. That is, in the illustrated example, a number of brush bristles are planted on the second top wall 42 as the rubbing portion 66, but a known sponge or brush part may also be attached. In the illustrated example, the rubbing portion 66 is disposed on the second top wall 42 so as to surround the discharge port 62 as shown in FIG. 1(B) when viewed from above, but the location can be changed as appropriate.
[0026] The valve member 70 is disposed inside the application tube portion 60 and includes a valve body 72 for closely contacting the valve seat surface portion 64 in an upwardly biased state so as to be able to rise and fall. In this embodiment, the valve member 70 comprises a substantially horizontal plate-shaped (disk-shaped in the illustrated example) valve body 72, a cylindrical body 76 suspended from the peripheral end of the valve body 72, and a contact 84 which is a rod-shaped body (a tubular body in the illustrated example) of a smaller diameter than the cylindrical body 76 and suspended from the center of the valve body 72. The cylindrical body 76 is composed of a pair of upper and lower ring bodies 78, 82 with an elastic spring 80, which serves as an upward biasing means for the valve body 72, interposed between them, and the upper ring body 78 is connected to the peripheral end of the valve body 72, and the lower ring body 82 is engaged with the support seat S. 2, a concave groove that engages with the engaging rib 59 of the cylindrical support portion 58 is provided around the outer circumferential surface of the lower ring body 82. Also, a claw portion 83 that comes into contact with the lower end surface of the cylindrical support portion 58 is provided around the lower end of the lower ring body 82. The ring bodies 78, 82 are formed in a short cylindrical shape, and are designed so that the elastic spring 80 occupies most of the vertical length of the cylindrical body 76. The cylindrical body 76 is disposed in a gap e between the column portion 24 and the surrounding cylinder 56. The elastic spring 80 is disposed through the gap e, extending from the inside of the support cylinder portion 58 to the inside of the application cylinder portion 60. In the illustrated example, the elastic spring 80 is formed as a coil spring (resin spring), but the structure can be modified as appropriate. In the illustrated example, the valve member 70 is integrally molded as a whole, but the structure thereof may be modified as appropriate.
[0027] In this embodiment, the valve body 72 is formed to have a diameter smaller than that of the base portion 60a of the application tube portion 60 and larger than that of the tip portion 60c. In this manner, in the state shown in FIG. 1 (when the second cap 40 is in the lowermost position), an upper portion 74 of the outer periphery of the valve body 72 abuts against the valve seat surface portion 64 of the tapered intermediate portion 60b, and the valve body 72 is sandwiched between the column portion 24 that pushes up the lower surface i of the valve body 72 and the valve seat surface portion 64, thereby sealing the portion 74 and the valve seat surface portion 64. The upper portion of the outer periphery of the valve body 72 is referred to as a seal surface portion 74. By sandwiching the valve body 72 between the valve seat surface portion 64 and the column portion 24, the sealability at the seal surface portion 74 is improved. In the prior art (e.g., Patent Document 1), the elastic force of a resin spring is used to press the valve plate against the valve seat surface to easily achieve sealing, so if the spring's resilience is insufficient or if the elasticity weakens due to elastic fatigue or deterioration over time, there is a possibility that sufficient pressing force cannot be obtained. In the present invention, the valve body 72 is clamped between the column portion 24 and the valve seat surface portion 64 by the locking force of the linking portion 50 and the linking receiving portion 30, and the valve body 72 is forcibly pressed against the valve seat surface portion 64, ensuring good sealing performance. The valve seat surface portion 64 and the valve body 72 (specifically, the seal surface portion 74 of the valve body 72) form a seal valve V. This seal valve V opens and closes as the contact 84 advances and retreats relative to the application tube portion 60. 2, the corners between the top surface of the valve body 72 and the outer circumferential surface of the upper ring body 78 are chamfered to form the seal surface portion 74 in the same tapered shape as the valve seat surface portion 64. This allows the valve seat surface portion 64 and the seal surface portion 74 to come into surface contact, improving the sealing performance.
[0028] The contactor 84 is a part for contacting the external surface T to be coated, and as shown in Figure 1 (A), by making its tip portion protrude outward from the application tube portion 60, it is formed so as to be movable forward and backward relative to the application tube portion 60. Note that "able to advance and retreat relative to the application tube portion 60" means that the application tube portion 60 retreats inward in the axial direction of the application tube portion 60 when pressed against the surface T to be applied, and advances outward when the pressure is released. The contact 84 is positioned above the application tube portion 60 in the state shown in FIG. 1(A), and has a circumferential groove 86 formed therearound.
[0029] The overcap 90 has a peripheral gripping wall 94 extending vertically from the peripheral edge of a top plate 92. The peripheral gripping wall 94 is detachably fitted to a suitable position of the second cap 40 (the outer surface of the annular protuberance 46 in the illustrated example).
[0030] In the above-described configuration, in the state shown in FIG. 1(A), the second cap 40 is in the lowermost position relative to the first cap 10, and the seal valve V is closed. In this state, the valve body 72 of the sealing valve V is sandwiched between the valve seat surface portion 64 of the application tube portion 60 and the column portion 24, and the upper side of the outer periphery of this valve body 72 (seal surface portion 74) is pressed against the valve seat surface portion 64 so as to bite into it, resulting in good sealing properties. This improves the sealing performance during distribution and storage of the product, and the contents will not spill out even if the application container is accidentally turned over from an upright position, for example. The state in which the valve body 72 is clamped between the valve seat surface portion 64 and the column portion 24 is maintained by the locking force between the linking portion 50 and the linking receiving portion 30, so that the clamped state will not be released unexpectedly during distribution or storage.
[0031] When performing a coating operation, from the state shown in Fig. 1(A), the overcap 90 is removed and the second cap 40 is raised (screwed up in the illustrated example) relative to the first cap 10, thereby displacing the second cap 40 from the lower limit position shown in Fig. 1(A) to the upper limit position shown in Fig. 3. In this state, the seal valve V is still closed. Then, as shown in FIG. 4, the application container is turned upside down, and the contact 84 is pressed against the external surface T to be applied (for example, the floor or wall of the bathroom). Then, the contact 84 retreats inward in the axial direction of the application tube 60, and the seal valve V opens. As a result, the liquid (not shown) in the container body 2 passes through the gap g between the surrounding tube 56 and the column 24, and the gap e between the tip 60c of the application tube 60 and the contact 84, and flows out from the discharge port 62 to the surface T to be applied. Then, the liquid that has flowed out onto the surface T to be applied can be spread through the rubbing portion 66. This allows the cleaning of the bathroom, especially the cleaning of partial dirt, to be performed efficiently with less effort and less tools. During the application operation, when the contact 84 is pressed against the surface T to be applied, the elastic spring 80 is compressed, and the contact 84 retracts together with the valve body 72 toward the inside in the axial direction of the application tube portion 60, and then, as shown by the imaginary line in Fig. 3, the lower surface i of the valve body 72 abuts against the valve body pressing portion 28. This causes the contact 84 and the valve body 72 to stop, and the elastic spring 80 is no longer compressed. This limits the range of compression deformation of the elastic spring 80. As shown in Fig. 3, if the length of the elastic spring 80 before the contactor 84 is pressed in is m, and the width to which the elastic spring 80 is compressed by pressing in the contactor 84 is n, the above configuration can prevent the compression width n from becoming excessively large. Therefore, the deformation strain (n / m) can be reduced, and the sagging (elastic fatigue) of the elastic spring 80 can be reduced. In addition, in the configuration of this embodiment, the support seat S of the elastic spring 80 is disposed at the lower part of the support tube part 58 that is extended downward from the application tube part 60. Therefore, the length m of the elastic spring 80 before compression can be made longer compared to the case where the support seat is disposed at the lower end of the application tube part 60, for example, without providing the support tube part 58. Therefore, the deformation distortion of the elastic spring 80 can be reduced, and the sag (elastic fatigue) of the elastic spring 80 is further reduced.
[0032] According to the above-mentioned configuration and action, a pillar portion 24 is provided protruding from the first top wall 14 of the first cap 10 toward the inside of the application tube portion 60 of the second cap 40, and when the second cap 40 is in the lowermost position, the valve body 72 is sandwiched between the valve seat surface portion 64 and the pillar portion 24, thereby improving the sealing condition during distribution and storage. Furthermore, by engaging the linking portion 50 of the second cap 40 with the linking receiving portion 30 of the first cap 10, the valve body 72 can be held in a sandwiched state, thereby ensuring improved sealing performance. When the contact 84 is pressed against the surface T to be coated with the valve seat surface 64 and the valve body 72 separated from each other, the lower surface i of the valve body 72 abuts against the valve body holding portion 28, thereby reducing the sagging of the elastic spring 80.
