Description

[Technical Field]

[0001] The present invention relates to an application container for applying a liquid content, and more particularly to an application container that can release internal pressure when the lid is opened even if the internal pressure increases. [Background technology]

[0002] A conventionally known application container for applying a liquid content such as a medicine contained in a container body includes a frame body attached to the mouth of the container body, and a valve body that is biased from the opening of the frame body toward the axial tip end and has its tip end protruding from the opening of the frame body, and the sealing surface on the outer periphery of the valve body comes into close contact with the periphery of the opening of the frame body, thereby airtightly sealing the inside and outside of the container (see, for example, Patent Document 1).

[0003] When applying the liquid contents, the application container is tilted so that the tip of the valve body faces downward, and the tip is pressed against the application surface, pushing the valve body against the frame body, thereby releasing the seal and applying the leaked liquid contents to the application surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 2553493 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the application container described in Patent Document 1 may have a problem in that the internal pressure of the container body is elevated relative to the external air pressure, for example, when the container body contains a liquid content such as a relatively highly volatile liquid agent, or when the container body is exposed to high outside air temperatures.If application is performed in such a state where the internal pressure of the container body is elevated relative to the external air pressure, when the seal between the frame body and the valve body is released, the pressure difference between the inside and outside of the container body causes a large amount of the liquid content to spray out onto the application surface.

[0006] The present invention aims to solve the above problems and to provide an application container that can make the internal pressure of the container body equal to the external air pressure when the cap body is opened, thereby preventing a large amount of the liquid contents from spraying out onto the application surface. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides an application container comprising: a container body in which the content liquid is stored; an application member attached to the mouth of the container body; and a cap body that is screwed onto the mouth of the container body so as to be openable and closable and covers the application member; the application member seals the mouth of the container body and comprises a frame body having an opening, and a valve body that opens and closes the opening of the frame body with a biased plug portion; the cap body comprises an inner cap that screws onto the mouth of the container body; an outer cap that covers the outside of the inner cap and is attached so as to be able to rotate freely within a predetermined angular range relative to the inner cap; and an inner plug that is attached so as to be able to rise and fall between the outer cap and the inner cap; and when the outer cap rotates within a predetermined angular range in the opening direction, the inner cap, while screwed onto the mouth portion, descends and presses down the plug portion of the valve body of the application member.

[0008] In an embodiment of the application container, the inner cap comprises an attachment inner wall that screws onto the mouth of the container body, and a rotation control cylindrical wall that is formed concentrically with the attachment inner wall and has a rotation groove recessed on its outer periphery that regulates the rotation range of the outer cap within a predetermined angular range; the outer cap comprises an outer peripheral wall that is rotatably attached to the outer periphery of the attachment inner wall of the inner cap, and a locking protrusion that protrudes radially from the inner periphery of the outer peripheral wall and regulates rotation within the rotation groove of the inner cap; the inner cap comprises a ring-shaped upper wall, a sealed inner cylinder that stands from the inner edge of the upper wall and has an inner plug that moves up and down on its inner periphery, and a vertical control cylindrical wall that stands outward from the upper surface of the upper wall concentrically with the sealed inner cylinder and controls the vertical movement of the inner plug; and the outer cap comprises an outer peripheral wall that is rotatably attached to the outer periphery of the inner cap, a top wall that extends inward from the upper end of the outer peripheral wall, and a locking protrusion that protrudes radially from the inner periphery of the top wall. the inner plug comprises a ring-shaped upper wall guided by the guide tube portion of the outer cap, a stopper tube suspended from the inner edge of the ring upper wall and with its outer periphery's lower end sliding along the inner periphery of the sealed inner tube of the inner cap, a push-down protrusion extending downward from the lower end of the stopper tube and capable of abutting against the stopper portion of the valve body, and an up-and-down movable tube wall suspended from a predetermined position on the ring upper wall and engaging with the up-and-down control tube wall of the inner cap; and the frame comprises, together with the outer upper part of the valve body, an attachment portion attached to the mouth of the container body, and a partition wall extending inward from the attachment portion and having an opening in its center, and the stopper portion of the valve body comprises a stopper protrusion protruding from the opening in the partition wall by a biasing member supported by the frame, and a sealing surface formed on the outer edge of the stopper protrusion and in close contact with the periphery of the opening in the partition. [Effects of the Invention]

[0009] By adopting the above-mentioned configuration, the application container of the present invention can rotate the outer cap of the closed cap body in the opening direction, thereby slightly opening the application member and releasing the pressure inside the container body before the lid begins to open, thereby preventing the contents from spraying out after the lid is opened.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Next, the application container of the present invention will be described with reference to examples and drawings. In the following description, the upward direction in FIG. 1(a) is referred to as "upper", the downward direction as "lower", the vertical direction as "axial direction", and the left-right direction as "radial direction".

[0012] (Example) In FIG. 1, A is a container body, B is an application member attached to the mouth 1 of the container body A, and C is a cap body that is screwed onto the mouth 1 of the container body A so as to be openable and closable and covers the application member B. The cap body C is composed of an inner cap D that covers the application member B on the inside and is screwed onto the mouth 1 of the container body A, an outer cap E that covers the outside of the inner cap D and is attached so that it can rotate freely within a predetermined angular range relative to the inner cap D, and an inner stopper F that is attached so that it can move up and down in the axial direction between the outer cap E and the inner cap D.

[0013] As shown in Figures 1 and 2, the container body A contains a liquid content such as a liquid cosmetic or medicine, and has a cylindrical mouth portion 1 at the top. The mouth portion 1 has a fitting portion 2 at the upper outer periphery that engages with and is attached to the applicator member B, and below the fitting portion 2 is a male screw portion 3 that screws into the inner cap D of the cap body C.

[0014] The application member B is attached to the top of the mouth 1 of the container body A, sealing the inside, and is composed of a frame body B1 having an opening 6 in the center, and a valve body B2 fixed between the frame body B1 and the mouth 1, which opens and closes the opening 6 of the frame body B1.

[0015] The frame body B1 is composed of the outer upper part of the valve body B2, an attachment part 5 that is attached to the outer upper part of the mouth part 1 of the container body A, and a ring-shaped partition wall 7 that extends inward from the inner upper end of the attachment part 5 and has an opening 6 drilled in the center. A valve body mounting recess 8 is provided at the bottom of the mounting portion 5, into which the upper end of the outer wall of the valve body B2 is mounted inward, and below the valve body mounting recess 8, an outer peripheral mounting portion 9 is formed, which is mounted by engaging with the fitting portion 2 of the mouth portion 1.

[0016] The valve body B2 is composed of a mounting tubular portion 10, the upper portion of which is mounted in the valve body mounting recess 8 of the frame body B1 and the outer periphery of which is inserted into the inner periphery of the mouth portion 1, a ring-shaped bottom wall 11 which extends inward from the lower end of the inner periphery of the mounting tubular portion 10, a spring tubular portion 12 which stands upright from the inner periphery of the bottom wall 11 and serves as a biasing member in the form of a spiral spring which can elastically deform up and down and allows the content liquid to pass between it, and a stopper portion 13 which is formed at the upper end of the spring tubular portion 12 and which opens and closes the opening 6 of the frame body B1. The plug portion 13 is located in the center of the upper surface, and under normal conditions, the elasticity of the spring tube portion 12 causes the lower outer end to be in close contact with the inner periphery of the opening 6, and the sealing plug protrusion 14 protrudes at an inclination that reduces in diameter toward the top, and the outer upper surface of the plug protrusion 14 forms a sealing surface 15 that is in close contact with the periphery of the opening 6 in the partition wall 7.

[0017] As shown in Figures 1 and 3, the inner cap D is composed of an attachment inner wall 20 that is screwed onto the outer periphery of the mouth 1 of the container body A, a ring-shaped stepped upper wall 21 that is formed inward from the upper end of the attachment inner wall 20, a rotation control barrel wall 22 that is erected concentrically with the attachment inner wall 20 from the inner edge of the stepped upper wall 21, a ring-shaped upper wall 23 that is formed from the upper end of the inner periphery of the rotation control barrel wall 22, a sealed inner tube 24 that is erected from the inner edge of the upper wall 23 and along whose inner periphery the inner plug F moves up and down in the axial direction, and an up-and-down control barrel wall 25 that is erected outward from the upper surface of the upper wall 23 concentrically with the sealed inner tube 24 and controls the elevation of the inner plug F.

[0018] The mounting inner wall 20 has a female threaded portion 27 threaded on the inner circumference that screws into the male threaded portion 3 of the container body A, and a rotary ridge 28 protruding from the lower outer periphery to guide the outer cap E so that it can rotate horizontally.

[0019] As shown in Figures 1(b) and 3(a), the rotation control cylinder wall 22 has a rotation groove 30 recessed into its outer periphery that regulates the rotation range of the outer cap E within an angle range α (60° in this embodiment) that faces each other at 180° intervals, and the rotation groove 30 has a start end locking portion 31a and a end end locking portion 31b recessed inward at the start end side 30a of the opening rotation direction end and the end end side 30b of the closing rotation direction end, which are separated by the angle range α, and a rotatable portion 31c is formed between the start end locking portion 31a and the end end locking portion 31b.

[0020] As shown in Figures 1(b) and 3, the upper and lower control cylinder walls 25 are formed with a spiral groove 34 recessed on their outer periphery, which rotates the inner plug F when the outer cap E rotates within an angle range α (60° in this embodiment, the same as the rotation groove 30) that faces each other at 180° intervals. The spiral groove 34 slopes upward at a height β from a starting end 34a on the right side, which is the end in the rotation direction for opening the cap, as seen in Figure 3(c), to a terminal end 34b on the left side, which is the end in the rotation direction for closing the cap. This allows the inner plug F to be raised and lowered in the axial direction as it rotates relative to the inner cap D, and each of the upper and lower control cylinder walls 25 has a crossover recess 35 recessed from the upper end of the outer periphery to the upper end near the circumferential center of the spiral groove 34.

[0021] As shown in Figures 1 and 4, the outer cap E comprises a lower outer peripheral wall 40 rotatably mounted on the outer periphery of the mounting inner wall 20 of the inner cap D, an upper outer peripheral wall 41 which is tapered from the upper end of the inner periphery of the lower outer peripheral wall 40 and extends in the axial direction, and a top wall 42 which extends from the upper end of the upper outer peripheral wall 41 so as to block the inward direction, and a guide tube portion 43 which guides the inside plug F so that it can be raised and lowered in the axial direction is attached to the underside of the top wall 42. In this embodiment, the outer peripheral wall of the outer cap E is divided into the lower outer peripheral wall 40 and the upper outer peripheral wall 41, but both may have the same diameter and not be divided into upper and lower parts.

[0022] The lower outer peripheral wall 40 has a rotation recess 45 formed in the lower inner peripheral portion thereof, which engages with the rotation ridge 28 of the mounting inner wall 20 of the inner cap D and mounts the inner cap D so that it can rotate horizontally.

[0023] The upper outer wall 41 protrudes radially from the inner circumference so as to face each other at 180° intervals, and is fitted into the start end locking portion 31a or the end end locking portion 31b of the inner cap D.The inner end face protrudes with a diameter that allows it to slide on the outer surface of the rotatable portion 31c, and a locking protrusion 46 protrudes to regulate rotation within the rotation groove 30.

[0024] As shown in FIG. 4(b), the guide tube portion 43 has a plurality of notched guide grooves 47 recessed in the axial direction and arranged at predetermined intervals (in this embodiment, three at intervals of 120°), and a bridging protrusion 48 protrudes from the lower end of the inner periphery.

[0025] As shown in Figures 1 and 5, the inner plug F comprises: a ring-shaped upper wall 50 that is guided by the inner periphery of the guide tube portion 43 of the outer cap E; a stopper tube 51 that hangs down from the inner edge of the ring-shaped upper wall 50 and whose lower end of its outer periphery slides along the inner periphery of the sealed inner tube 24 of the inner cap D; a cylindrical push-down protrusion 52 that reduces in diameter and extends downward from the lower end of the inner periphery of the stopper tube 51 and has a bottom portion 52a that closes the inside; and an up-and-down movable tube wall 53 that hangs down from a predetermined position on the underside of the ring-shaped upper wall 50 and engages with the up-and-down control tube wall 25 of the inner cap D to move the inner plug F up and down.

[0026] As shown in Figure 5(b), multiple ring upper walls 50 (in this embodiment, three at 120° intervals) are arranged on the outer periphery at predetermined intervals, and are inserted into the notched guide grooves 47 of the guide tube portion 43 of the outer cap E, and have anti-rotation protrusions 55 that guide the inner plug F as it moves up and down in the axial direction so that it does not rotate relative to the outer cap E, and holes 56 that penetrate from top to bottom are drilled at predetermined positions inside the vertically movable tube wall 53.

[0027] The plug cylinder 51 has a contact portion 57 at its lower outer periphery, the tip of which slides in close contact with the inner periphery of the sealing inner cylinder 24 of the inner cap D and moves up and down while sealing the inside of the sealing inner cylinder 24.

[0028] The vertically movable cylindrical wall 53 has vertically movable protrusions 58 protruding from the lower end of the inner periphery, which are opposed at 180° intervals and engage with the spiral groove 34 of the vertical control cylindrical wall 25 of the inner cap D, rotating through an angle range α (60° in this embodiment) between the starting end side 34a and the terminal end side 34b, and raising and lowering the inner plug F by the height β of the spiral groove 34. The vertically movable protrusion 58 engages with the climbing recess 35 of the vertical control cylinder wall 25 from above, is guided, climbs over, and engages within the spiral groove 34 .

[0029] Next, the manner of use and effects of the application container of the present invention will be described. First, the cap body C is assembled by inserting the inner plug F from above the inner cap D after aligning it with the inner cap D, and then attaching it. At this time, the push-down projection 52 and the stopper cylinder 51 of the inner plug F are inserted into the sealed inner cylinder 24 of the inner cap D, and the sealing portion 57 is slid downward. As the inside plug F continues to descend, the vertically movable protrusions 58 of the vertically movable cylindrical wall 53 of the inside plug F are guided into the climbing recesses 35 on the outer periphery of the vertically control cylindrical wall 25 of the inner cap D, climb over the climbing recesses 35, and engage with the respective spiral grooves 34, stopping the descent and setting the inside plug F in the inner cap D.

[0030] Next, the outer cap E is positioned over the inner cap D together with the inside stopper F, and the inner cap D is attached inside the outer cap E. At this time, each of the rotation stopper protrusions 55 of the inner plug F is set into each of the notched guide grooves 47 of the guide tube portion 43 of the outer cap E, and each of the locking protrusions 46 in the upper outer wall 41 of the outer cap E is set from above into each of the rotation grooves 30 on the outer circumference of the rotation control tube wall 22 of the inner cap D, and is lowered while aligning them.Finally, the rotation recess 45 on the inner circumference of the lower outer wall 40 of the outer cap E engages with the rotation protrusion 28 on the outer circumference of the mounting inner wall 20 of the inner cap D, and the inner cap D and inner plug F are attached to the outer cap E, forming the cap body C.

[0031] The application member B is formed by setting the upper part of the mounting tube portion 10 of the valve body B2 into the valve body mounting recess 8 of the frame body B1, and then attached to the mouth portion 1 of the container body A filled with the content liquid by capping. At this time, the plug portion 13 is urged into tight contact with the opening 6 of the partition wall 7 of the frame body B1 by the elasticity of the spring tube portion 12 of the valve body B2, closing the partition wall 7 and sealing the inside of the container body A. Furthermore, the upper part of the mounting tube portion 10 of the valve body B2 is set in the valve body mounting recess 8 of the frame body B1, and the outer peripheral mounting portion 9 of the valve body mounting recess 8 fits into the fitting portion 2 of the mouth portion 1 of the container body A, so that the valve body B2 is fixed in the frame body B1 and the application member B is attached to the container body A.

[0032] The set cap body C is placed over the mouth 1 of the container body A on which the application member B is set, and screwed together while rotating in the lid closing direction to form a closed application container. At this time, as the outer cap E rotates in the closing direction, the tip of the locking protrusion 46 of the outer cap E is initially positioned and abuts against the rotatable portion 31c of the rotation groove 30 of the rotation control cylinder wall 22 of the inner cap D, sliding against it, so that the outer cap E spins freely against the inner cap D, which is screwed into the upper part of the mouth 1 of the container body A and creates resistance, preventing it from rotating.

[0033] When the outer cap E rotates freely in the closing direction relative to the inner cap D, which does not rotate, the inner plug F rotates together with the outer cap E because the respective cutout guide grooves 47 of the guide tube portion 43 of the outer cap E and the respective rotation stopper protrusions 55 of the inner plug F are engaged in the rotational direction. When the inner plug F rotates in the closing direction relative to the inner cap D, which does not rotate, the vertically moving protrusion 58 of the vertically moving cylindrical wall 53 of the inner plug F rotates in the closing direction within the spiral groove 34 of the vertical control cylindrical wall 25 of the inner cap D, and is lifted upward due to the inclination of the spiral groove 34. Furthermore, as shown in Figure 6, each of the rotation stopper protrusions 55 of the inner plug F engages with each of the notched guide grooves 47 of the guide tube portion 43 of the outer cap E, and the inner plug F is guided axially within the outer cap E, so that the inner plug F rises while rotating within the outer cap E, compared to the inner cap D which does not rotate.

[0034] As the outer cap E and inner plug F rotate freely in the closing direction relative to the inner cap D, which does not rotate, the tip of each locking protrusion 46 of the outer cap E engages with the terminal locking portion 31b in each rotation groove 30 of the inner cap D, and the side of the locking protrusion 46 abuts against the terminal side 30b, as shown in Figure 6(b).In addition, the side of the up-and-down moving protrusion 58 of the inner plug F abuts against the terminal side 34b in the spiral groove 34 of the inner cap D.Furthermore, when the outer cap E is rotated, the inner cap D is also pushed in the rotational direction at the abutting portion, and the inner cap D rotates together with it. When the inner cap D rotates due to the rotational force of the outer cap E, the inner cap D and the mouth portion 1 of the container body A are screwed together, and finally, as shown in Figure 1, the cap body C is screwed onto the container body A to complete the closed application container.

[0035] When the lid is closed, the inside of the inner cap D is sealed by the screw engagement of the mouth 1 of the container body A with the inner cap D and the sealing between the outer periphery of the sealing part 57 of the stopper tube 51 of the inside plug F and the inner periphery of the sealing inner tube 24 of the inner cap D. In addition, due to the elasticity of the spring tube portion 12 of the valve body B2, the plug portion 13 is forced against the opening 6 of the partition wall 7 of the frame body B1, causing the sealing surface 15 to adhere tightly, blocking the opening 6 of the partition wall 7 and sealing the inside of the container body A.

[0036] When using the application container, when the outer cap E is rotated in the opening direction, it screws onto the container body A, creating resistance, and the tips of the locking protrusions 46 of the rotating outer cap E disengage from the terminal locking portions 31b in the rotation grooves 30 of the inner cap D relative to the non-rotating inner cap D, causing a clicking sensation, and the tips of the locking protrusions 46 slide within the rotatable portions 31c in the rotation grooves 30, causing the outer cap E to spin freely in the opening direction.

[0037] When the outer cap E rotates freely in the opening direction relative to the inner cap D, which does not rotate, the inner plug F rotates together with the outer cap E because the respective notched guide grooves 47 of the guide tube portion 43 of the outer cap E and the respective rotation stopper protrusions 55 of the inner plug F are engaged in the rotational direction. When the inner plug F rotates in the opening direction relative to the inner cap D which does not rotate, the vertically moving protrusion 58 of the vertically moving cylindrical wall 53 of the inner plug F disengages from the terminal end side 34b of the spiral groove 34 of the vertical control cylindrical wall 25 of the inner cap D, rotates within the spiral groove 34 in the opening direction toward the starting end side 34a, and is pushed downward by the inclination of the spiral groove 34. Furthermore, the rotation stopper protrusions 55 of the inner plug F engage with the respective notched guide grooves 47 of the guide tube portion 43 of the outer cap E, and the inner plug F is guided axially within the outer cap E, so that the inner plug F rotates within the outer cap E and descends, compared to the inner cap D which does not rotate.

[0038] As the inner plug F descends relative to the inner cap D, as shown in Figure 7(a), the bottom surface 52a of the pushing-down protrusion 52 of the descending inner plug F abuts against the upper surface of the plug protrusion 14 of the plug portion 13 of the valve body B2 of the applicator B, pushing down the plug portion 13 and releasing the tight contact between the opening 6 of the frame body B1 and the inner edge of the lower surface of the partition wall 7 and the sealing surface 15 of the plug portion 13 of the valve body B2, creating a gap.

[0039] In the application container of this embodiment, while rotating in the lid opening direction, before the mouth portion 1 of the container body A and the inner cap D are unscrewed, a gap is created between the stopper portion 13 of the valve body B2 of the application member B and the opening 6 of the frame body B1. Therefore, even if the internal pressure inside the container body A is high, the pressure is released from the gap to the top of the application member B. Furthermore, due to the screwing of the mouth portion 1 of the container body A and the inner cap D and the sealing between the outer periphery of the sealing portion 57 of the stopper tube 51 of the middle stopper F and the inner periphery of the sealed inner tube 24 of the inner cap D, the content liquid leaking from the gap due to internal pressure can be prevented from spraying out from inside the inner cap D and contaminating the outside.

[0040] When the outer cap E and inner plug F are rotated freely in the opening direction relative to the inner cap D, which is not rotating, the tip of each locking protrusion 46 of the outer cap E engages with the starting locking portion 31a in each rotation groove 30 of the inner cap D, and the side of the locking protrusion 46 abuts against the starting side 30a, as shown in Figure 7(b).In addition, the side of the up-and-down moving protrusion 58 of the inner plug F abuts against the starting side 34a in the spiral groove 34 of the inner cap D.Furthermore, when the outer cap E is rotated, the inner cap D is also pushed in the rotational direction by the abutting portion and rotates together with the inner cap D. When the inner cap D rotates together with the rotational force of the outer cap E, the inner cap D and the mouth part 1 of the container body A are unscrewed, causing the cap body C to rise, and finally the container body A is left with the cap body C removed and the application member B attached.

[0041] Furthermore, as the cap body C is unscrewed and rises from the mouth 1 of the container body A, the pushing-down protrusion 52 of the inner plug F, which had been abutting against the upper surface of the plug protrusion 14 of the plug portion 13 of the valve body B2 of the applicator B and pressing down before the cap body C was removed, also rises and is removed, and the elasticity of the spring tube portion 12 of the valve body B2 urges the plug portion 13 into tight contact with the opening 6 of the partition wall 7 of the frame body B1, blocking the opening 6 of the partition wall 7, and the applicator B seals the inside of the container body A.

[0042] When applying the liquid contents in the container body A, as shown in Figure 2(b), the application container is turned upside down and the tip of the plug protrusion 14 of the valve body B2 of the application member B is pressed against the desired application surface T, causing the plug portion 13 to be pushed in, releasing the adhesion between the periphery of the opening 6 of the frame body B1 and the sealing surface 15 of the plug portion 13 of the valve body B2, creating a gap through which the liquid contents pass and are applied to the application surface T. Furthermore, when the pressure of the tip of the plug protrusion 14 of the valve body B2 against the application surface T is stopped, the elasticity of the spring tube portion 12 of the valve body B2 urges the plug portion 13 into tight contact with the opening 6 of the partition wall 7 of the frame body B1, blocking the opening 6 of the partition wall 7 and stopping the content liquid. The application member B can be thinly spread and applied to the application surface T by repeatedly pressing the stopper part 13 against the application surface T to cause the content liquid to seep out and stopping the pressure to stop the content liquid from seeping out.

[0043] In the application member B of this embodiment, the stopper portion 13 is biased by the elasticity of the spring tube portion 12 of the valve body B2, so that when the stopper portion 13 is pressed, it acts as a cushion and can gently abut against the application surface T, and by repeatedly pressing the stopper portion 13, a massage effect can also be expected. Furthermore, by making the tip of plug protrusion 14 of plug 13 of applicator B out of a felt or brush-like material that has some degree of shape retention and that can be pressed down from above, it is possible to broaden the range of uses for application. Furthermore, an applicator (such as a sponge-like member) may be provided on the top of plug 13 to apply the content liquid. When an applicator is provided on top of the plug portion 13, the inner plug F of the cap body C presses down the plug portion 13 of the valve body B2 via the applicator.

[0044] After applying the liquid content in the container body A, when closing the container body A again with the cap body C, the cap body C is placed over the mouth 1 of the container body A on which the application member B is set, and is screwed on while rotating in the closing direction. At this time, as the outer cap E rotates in the closing direction, the tip of the locking protrusion 46 of the outer cap E disengages from the starting locking portion 31a in the rotation groove 30 of the non-rotating inner cap D and slides against the rotatable portion 31c, causing the outer cap E and inner plug F to rotate freely in the closing direction. When the outer cap E and the inner stopper F are rotated idly, the spiral groove 34 of the upper and lower control cylinder wall 25 of the inner cap D causes the inner stopper F to rise within the outer cap E. As shown in Figure 6, the tip of each of the locking protrusions 46 of the outer cap E engages with the terminal locking portion 31b in each of the rotation grooves 30 of the inner cap D, and the side of the locking protrusion 46 abuts against the terminal side 30b. In addition, the side of the up-and-down moving protrusion 58 of the inner stopper F abuts against the terminal side 34b in the spiral groove 34 of the inner cap D. When the outer cap E is further rotated, the inner cap D is also pushed in the rotational direction by the abutting portion and rotates together with the inner cap D, progressing the screwing. As shown in Figure 1, the cap body C is screwed onto the container body A to close the lid. [Industrial Applicability]

[0045] The applicator container of the present invention is composed of an applicator member attached to the mouth of the container body, and a cap body consisting of an inner cap, an outer cap, and an inner stopper, which is screwed onto the mouth of the container body so as to be able to open and close, and which covers the applicator member.By rotating the outer cap of the closed cap body in the lid opening direction, the applicator member can be slightly opened to release the pressure inside the container body before the lid opening begins, making it an applicator container that can prevent the content liquid from spraying out after the lid is opened, and is particularly suitable as an applicator container for cosmetics, medicines, etc., which may have a rise in internal pressure.
