Description

Technical Field

[0005] , ,

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

Background Art

[0002] As an application container for applying a content liquid such as a drug stored in a container body, there is conventionally known an application container including a frame body attached to the mouth portion of the container body and a valve body disposed in a state of being biased from the opening of the frame body toward the axial front end side, with the tip portion protruding from the opening of the frame body. When the sealing surface on the outer peripheral side of the valve body and the peripheral edge of the opening of the frame body are in close contact, the inside and outside of the container are hermetically sealed (see, for example, Patent Document 1).

[0003] When applying the content liquid, the application container is tilted so that the tip portion of the valve body faces downward, the tip portion is pressed against the application surface, and the valve body is pushed into the frame body to release the seal, and the oozing content liquid is applied to the application surface.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the application container described in Patent Document 1, for example, when a content liquid such as a highly volatile liquid agent is stored in the container body and the container body is exposed to a high outside air temperature, the internal pressure of the container body may be increased relative to the external atmospheric pressure. When application is performed in such a state where the internal pressure of the container body is increased relative to the external atmospheric pressure, there is a problem that when the seal between the frame body and the valve body is released, a large amount of the content liquid is ejected onto the application surface due to the pressure difference between the inside and outside of the container body.

[0006] The present invention aims to solve the above problems and provides a coating container that can prevent a large amount of liquid from spraying onto the coating surface by making the internal pressure of the container body equal to the external air pressure when the cap is opened. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides a coating container comprising: a container body containing a liquid contents; a coating 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 coating member. The coating member comprises a frame body that seals the mouth of the container body and has an opening, and a valve body that opens and closes the opening of the frame body with a biased stopper. The cap body comprises an inner cap that is screwed onto the mouth of the container body and has an inwardly formed, axially deformable push-down portion, and an outer cap that covers the outside of the inner cap and pushes down the push-down portion in the axial direction while rotating freely within a predetermined angular range relative to the inner cap. When the outer cap is rotated within a predetermined angular range in the opening direction, the inner cap, while screwed onto the mouth, lowers the push-down portion and pushes down the stopper portion of the valve body of the coating member.

[0008] As an embodiment of the coating container, the inner cap comprises a ring-shaped upper wall that closes the mouth of the container body and a deformable connecting portion connected to an inward pressing portion from the inner edge of the upper wall, the pressing portion comprises a pressing wall connected via the deformable connecting portion, a pressing cylinder portion erected from the pressing wall, and a cam recess formed in the pressing cylinder portion, and the outer cap comprises an outer wall rotatably mounted on the outer circumference of the inner cap, a top wall extending inward from the upper end of the outer wall, a rotating pressing cylinder portion suspended from the lower surface of the top wall, and a pressing projection protruding from the inside of the rotating pressing cylinder portion and engaging with the cam recess of the pressing cylinder portion of the inner cap, and the deformable connecting portion comprises an outer projection extending inward from the inner edge of the upper wall, an arc-shaped piece extending in an arc shape from the tip of the outer projection, and an arc The structure is characterized by having an inner projection extending from the other end of the piece toward the downward wall, and a valve band formed from the same, and the deformable connecting part is characterized by having a bellows deformable wall formed from a mountain wall portion connected from the inner edge of the upper wall and folded upward, and a valley wall portion connected from the downward wall and folded downward, and the inner cap is characterized by having a mounting inner wall that screws into the mouth of the container body, and a rotation control cylinder wall formed concentrically with the mounting inner wall and having a rotation groove recessed on its outer circumference that restricts the rotation range of the outer cap within a predetermined angular range, and the outer cap is characterized by having an outer circumference wall that is rotatably mounted on the outer circumference of the mounting inner wall of the inner cap, and a locking projection projecting radially from the inner circumference of the outer circumference wall that restricts rotation within the rotation groove of the inner cap. [Effects of the Invention]

[0009] By adopting the above configuration, the coating container of the present invention allows the coating member to be slightly opened and the pressure inside the container body to be released before the lid is fully opened by rotating the outer cap of the closed cap body in the opening direction, thereby preventing the contents from spraying out after the lid is opened.

[0011] Next, the coating container of the present invention will be described with reference to the drawings, using examples. In the following explanation, as seen in Figure 1(a), the upward direction will be referred to as "up," the downward direction as "down," the vertical direction as the "axial direction," and the left-right direction as the "radial direction."

[0012] (Example 1) In Figure 1, A is the container body, B is the coating member attached to the opening 1 of the container body A, and C is a cap body that is screwed onto the opening 1 of the container body A so as to be openable and closable and covers the coating member B. The cap body C includes an inner cap D that covers the application member B inwardly, is screwed onto the mouth portion 1 of the container body A, and has an inwardly formed pressing portion E that is axially deformable, and an outer cap F that covers the outside of the inner cap D and presses down the pressing portion E of the inner cap D axially while idling within a predetermined angular range α with respect to the inner cap D.

[0013] As shown in FIGS. 1 and 2, the container body A contains a liquid cosmetic, medicine, etc. as the content liquid, has a cylindrical mouth portion 1 at the upper part, and the mouth portion 1 has a fitting portion 2 that engages with and mounts the application member B at the upper outer periphery, and a male screw portion 3 that is screwed with the inner cap D of the cap body C is provided below the fitting portion 2.

[0014] As shown in FIG. 2, the application member B is mounted on the upper part of the mouth portion 1 of the container body A, seals the inside, and includes a frame body B1 that has an opening 6 at the center, and a valve body B2 that is fixed between the frame body B1 and the mouth portion 1 and opens and closes the opening 6 of the frame body B1.

[0015] The frame body B1 includes a mounting portion 5 that is mounted on the upper outer periphery of the mouth portion 1 of the container body A together with the upper outer side of the valve body B2, and a ring-shaped partition wall 7 that extends inwardly from the upper end of the inner periphery of the mounting portion 5 and has an opening 6 formed at the center. At the lower part of the mounting portion 5, a valve body mounting recess 8 for mounting the upper end portion of the outer wall of the valve body B2 inwardly is provided, and below the valve body mounting recess 8, an outer peripheral mounting portion 9 that fits and mounts with the fitting portion 2 of the mouth portion 1 is formed.

[0016] The valve body B2 has an upper part (flange) mounted in the valve body mounting recess 8 of the frame body B1, a mounting cylinder portion 10 whose outer periphery is inserted into the inner periphery of the mouth portion 1, a ring-shaped bottom wall 11 that extends inwardly from the lower end of the inner periphery of the mounting cylinder portion 10, a spring cylinder portion 12 that stands from the inner peripheral edge of the bottom wall 11 and is helical spring-shaped and axially elastically deformable and allows the content liquid to pass through, and a plug portion 13 that is formed at the upper end of the spring cylinder portion 12 and opens and closes the opening 6 of the frame body B1. The plug portion 13 is provided at the center of the upper surface. Normally, due to the elasticity of the spring cylinder portion 12, the outer peripheral lower end portion is in close contact with the inner periphery of the opening 6 and is sealed. A plug protrusion 14 that blocks it protrudes with an inclination that reduces the diameter upward. The upper surface of the outer edge from the plug protrusion 14 is a sealing surface 15 that is in close contact with the peripheral edge of the opening 6 of the partition wall 7.

[0017] As shown in FIGS. 1 and 3, the inner cap D includes a mounting inner wall 20 that is screwed onto the outer periphery of the mouth portion 1 of the container body A, a ring-shaped stepped upper wall 21 formed inward from the upper end of the mounting inner wall 20, a rotation control cylinder wall 22 erected concentrically with the mounting inner wall 20 from the inner edge of the stepped upper wall 21, a ring-shaped upper wall 23 formed from the upper part of the inner periphery of the rotation control cylinder wall 22, a sealing cylinder 24 erected on the upper surface of the upper wall 23, and a pressing-down portion E that is continuously provided from the inner edge opening 23a of the upper wall 23 through a later-described deformation connecting portion and can be deformed by being pressed downward in the axial direction with respect to the upper wall 23.

[0018] The mounting inner wall 20 has a female screw portion 27 screwed onto the male screw portion 3 of the container body A on the inner periphery, and a rotation protrusion 28 for horizontally rotatably mounting the outer cap F protrudes on the lower part of the outer periphery.

[0019] As shown in FIGS. 1(b) and 3(b), the rotation control cylinder wall 22 has rotation grooves 30 recessed on the outer periphery at an angular range α (in this embodiment, 0° to 90° and 180° to 270°, each with a range of 90°) that oppose each other at 180° intervals to regulate the rotation range of the outer cap F. The rotation grooves 30 have an open-side locking portion 31a and a closed-side locking portion 31b recessed inward at an angular range α from the open-side end 30a at the end in the opening rotation direction (in this embodiment, 0°, 180°) and the closed-side end 30b at the end in the closing rotation direction (in this embodiment, 90°, 270°). The space between the open-side locking portion 31a and the closed-side locking portion 31b is a rotatable portion 31c.

[0020] As shown in Figures 1(b) and 3(b), the pressing section E is composed of a connecting ring 36 connected to the inner edge opening 23a of the upper wall 23 via connecting pieces 35 arranged at 90° intervals at four locations (45°, 135°, 225°, and 315° in this embodiment), creating a gap inward; deformable thin-walled pieces 37 arranged at 90° intervals at four locations (0°, 90°, 180°, and 270° in this embodiment) from the inner edge of the connecting ring 36; a disc-shaped pressing wall 38 connected via the thin-walled pieces 37, creating a gap inward; and a pressing cylinder portion 39 erected on the outer edge of the pressing wall 38. Here, the thin-walled piece 37 constitutes a deformed connecting portion.

[0021] The push-down cylinder portion 39 has cam recesses 40 that push down the push-down cylinder portion 39 as the outer cap F rotates horizontally, in opposing angular ranges α (in this embodiment, 0° to 90° and 180° to 270°, each in a range of 90°) at 180° intervals from the upper end. The bottom surface portion 41 of each cam recess 40 consists of an open-side high bottom portion 41a where the open-side end 40a at the opening-side rotation end (0° and 180° in this embodiment) is the highest point of height β, and a closed-side low bottom portion 41b where the closed-side end 40b at the closing-side rotation end (90° and 270° in this embodiment) is the lowest point of height γ. Between the open-side high bottom portion 41a and the closed-side low bottom portion 41b (in this embodiment, between 90° and 0°), there is an inclined bottom portion 41c that slopes downward from height β to height γ.

[0022] As shown in Figures 1 and 4, the outer cap F comprises a lower outer peripheral wall 45 that is horizontally rotatably mounted on the outer circumference of the inner wall 20 of the inner cap D, an upper outer peripheral wall 46 that is reduced in diameter from the upper inner end of the lower outer peripheral wall 45 and extends in the axial direction, and a top wall 47 that extends from the upper end of the upper outer peripheral wall 46 to close the inside. The top wall 47 has a rotating push cylinder portion 48 that is suspended from the center of the lower surface and whose inner circumference engages with the upper part of the push-down cylinder portion 39 of the push-down portion E, and a sealing rotating cylinder 49 that is suspended from the outside of the rotating push cylinder portion 48 and whose lower inner circumference is horizontally rotatably mounted on the upper outer circumference of the sealing cylinder 24 of the inner cap D. In this embodiment, the outer peripheral wall of the outer cap F is divided into a lower outer peripheral wall 45 and an upper outer peripheral wall 46, but they may be made of the same diameter and not divided into upper and lower sections.

[0023] The lower outer peripheral wall 45 has a rotatable recess 51 in its lower inner peripheral portion that engages with the rotatable projection 28 of the inner wall 20 for mounting the inner cap D, allowing the inner cap D to be mounted so that it can rotate horizontally.

[0024] The upper outer peripheral wall 46 is provided with radial projections on the inner circumference at 180° intervals, facing each other, and is fitted into the open-side locking portion 31a or the closed-side locking portion 31b of the inner cap D. The inner end face is provided with a diameter that allows it to slide against the outer peripheral surface of the rotatable portion 31c, and a locking projection 53 is provided that restricts rotation within the rotation groove 30 to an angular range α (90° in this embodiment).

[0025] As shown in Figures 1(b) and 4(b), the rotating push cylinder portion 48 has an inner circumferential recess 55 in its lower inner circumference into which the outer circumference of the push-down cylinder portion 39 of the push-down portion E is inserted. Within the inner circumferential recess 55 are facing each other at 180° intervals (90° and 270° in this embodiment) and engage with the respective cam recesses 40 of the push-down cylinder portion 39 of the push-down portion E, rotating within an angular range α (90° in this embodiment) between the open end 40a and the closed end 40b. A push-down projection 56 is formed at approximately a height γ from the upper end of the inner circumferential recess 55, with its lower end contacting the bottom surface portion 41 of the cam recess 40, and pressing down the push-down portion E due to the inclination of the bottom surface portion 41.

[0026] Next, the usage modes and effects of the coating container of the present invention will be described. First, the cap body C is assembled by aligning and inserting the outer cap F from above the inner cap D, which has the press-down portion E integrally molded on the inside. At that time, the outer cap F is placed over the inner cap such that the inside of the locking projection 53, which is projected opposite to the inner circumference of the upper outer peripheral wall 46 of the outer cap F, is located within the closed-side locking portion 31b of each rotation groove 30 of the rotation control cylinder wall 22 of the inner cap D, and the downward projection 56, which is projected opposite from the inner peripheral recess 55 of the rotation push cylinder portion 48 of the outer cap F, is located on the closed-side lower bottom portion 41b of the closed-side end 40b of each cam recess 40 of the downward projection 39 of the downward projection E formed inside the inner cap D.

[0027] Finally, the rotating recess 51 on the inner circumference of the lower outer circumference wall 45 of the outer cap F fits onto the rotating projection 28 on the outer circumference of the inner wall 20 of the inner cap D, and the lower inner circumference of the sealing rotating cylinder 49 of the outer cap F is attached to the upper outer circumference of the sealing cylinder 24 of the inner cap D, so that the outer cap F is mounted so as to be horizontally rotatable relative to the inner cap D, and the inner cap D is set inside the outer cap F to form a cap body C.

[0028] The coating member B is formed by setting the upper part (flange) of the mounting cylinder portion 10 of the valve body B2 into the valve body mounting recess 8 of the frame body B1, and then attaching it to the mouth portion 1 of the container body A, which is filled with the liquid, by pressing it in. At that time, the elasticity of the spring cylinder portion 12 of the valve body B2 biases the plug portion 13 to the opening 6 of the partition wall 7 of the frame body B1, causing it to seal tightly and close the partition wall 7, thereby sealing the inside of the container body A. Furthermore, the upper part (flange) of the mounting cylinder portion 10 of the valve body B2 is set in the valve body mounting recess 8 of the frame B1, and the outer mounting portion 9 of the valve body mounting recess 8 fits with the fitting portion 2 of the mouth portion 1 of the container body A, so that the valve body B2 is fixed inside the frame B1 and the coating member B is attached to the container body A.

[0029] As shown in Figure 5, the cap body C, which has been aligned and set, is placed over the opening 1 of the container body A in which the coating member B is set, and screwed in while rotating in the closing direction to form a closed coating container. In this case, when the outer cap F rotates in the closing direction, the side surfaces of the tips of each locking projection 53 of the outer cap F contact the closed end 30b surface of each rotation groove 30 of the rotation control cylinder wall 22 of the inner cap D. Also, the side surfaces of each pressing projection 56 of the rotation push cylinder portion 48 of the outer cap F contact the closed end 40b surface of each cam recess 40 of the inner cap D. Furthermore, when the outer cap F is rotated, the inner cap D is also pushed in the rotational direction at the contact points, and the inner cap D rotates together with it. As the rotational force of the outer cap F causes the inner cap D to rotate, the screwing of the inner cap D with the opening 1 of the container body A progresses, and finally, as shown in Figure 1, the cap body C is screwed onto the container body A to complete the closed coating container.

[0030] In this embodiment, when the cap body C is set or when it is screwed onto the container body A to close it, as shown in Figure 5 or Figure 1, the pressing projections 56 of the rotating pressing cylinder portion 48 of the outer cap F, each at height γ, fit onto the closed-side lower bottom portion 41b at height γ on the closed-side end 40b side within the cam recess 40 of the pressing cylinder portion 39 of the pressing cylinder portion E, and the pressing cylinder portion 39 of the pressing cylinder portion E is inserted into the inner circumference recess 55 of the rotating pressing cylinder portion 48 of the outer cap F, fixing the pressing cylinder portion E without pressing it down against the inner cap D.

[0031] The inner cap D is sealed by the screw-fitting of the opening 1 of the container body A with the inner cap D. Furthermore, even if the pressure inside the inner cap D rises, the pressure is released through the gap between the connecting ring 36 and the pressing wall 38 of the pressing portion E inside the inner rim opening 23a of the upper wall 23 of the inner cap D. The sealing of the upper outer circumference of the sealing cylinder 24 of the inner cap D and the upper inner circumference of the sealing rotating cylinder 49 of the outer cap F seals the inside of the sealing rotating cylinder 49 of the outer cap F, so the cap body C will not come off the opening 1 of the container body A. Furthermore, the elasticity of the spring cylinder portion 12 of the valve body B2 biases the stopper portion 13 against the opening 6 of the partition wall 7 of the frame body B1, causing the sealing surface 15 to make close contact, closing the opening 6 of the partition wall 7 and sealing the inside of the container body A.

[0032] When using the coating container, rotating the outer cap F in the opening direction disengages the locking projections 53 of the rotating outer cap F from the closing locking portions 31b in the rotating grooves 30 of the inner cap D, which is screwed onto the container body A and does not rotate. This causes a clicking sensation, and the tips of the locking projections 53 slide within the rotatable portions 31c in the rotating grooves 30, allowing the outer cap F to spin freely in the opening direction.

[0033] Furthermore, when the outer cap F rotates freely in the opening direction relative to the inner cap D, the pressing projection 56 of the rotating pressing cylinder portion 48 of the outer cap F rotates in the opening direction within the cam recess 40 of the pressing cylinder portion 39 of the pressing portion E, and the lower surface of the pressing projection 56 slides in contact with the inclined bottom portion 41c of the cam recess 40, and the inclination of the inclined bottom portion 41c pushes down the pressing cylinder portion 39 and the pressing wall 38. The pressing motion of the pressing cylinder portion 39 and the pressing wall 38 causes the deformable thin-walled piece 37 of the pressing portion E to deform, and the pressing cylinder portion 39 and the pressing wall 38 move downward relative to the upper wall 23 of the inner cap D.

[0034] As the outer cap F rotates relative to the inner cap D, and the pressing portion E descends relative to the inner cap D, the lower surface of the pressing wall 38 of the descended pressing portion E comes into contact with the upper surface of the plug projection 14 of the plug portion 13 of the valve body B2 of the coating member B, pressing down the plug portion 13, releasing the tight seal between the opening 6 of the frame B1 and the lower inner edge of the partition wall 7 and the sealing surface 15 of the plug portion 13 of the valve body B2, and creating a gap.

[0035] In the coating container of this embodiment, when the cap body C is rotated in the opening direction, a gap is formed between the stopper portion 13 of the valve body B2 of the coating member B and the opening 6 of the frame body B1 before the screw connection between the mouth portion 1 of the container body A and the inner cap D is released. Therefore, even if the pressure inside the container body A is high, the pressure is released upward through the gap to the coating member B. Furthermore, the screw connection between the mouth portion 1 of the container body A and the inner cap D, and the seal between the outer circumference of the sealing cylinder 24 of the inner cap D and the inner circumference of the sealing rotating cylinder 49 of the outer cap F, prevent the liquid contents that would leak out through the gap due to internal pressure from spraying out from inside the inner cap D and outer cap F and contaminating the outside.

[0036] Furthermore, when the outer cap F is rotated freely in the opening direction, as shown in Figure 6, the lower surface of the push-down projection 56 comes into contact with the upper surface of the opening-side high bottom portion 41a of the cam recess 40, stopping the pushing down on the push-down portion E. At the same time, the tip of the locking projection 53 on the upper outer peripheral wall 46 of the outer cap F engages with the opening-side locking portion 31a in the rotating groove 30 of the inner cap D, and the side surface of the locking projection 53 comes into contact with the opening-side end 30a surface. Additionally, the side surface of the rotating push cylinder portion 48 of the outer cap F comes into contact with the opening-side end 40a surface in the cam recess 40 of the inner cap D. Furthermore, when the outer cap F is rotated, the inner cap D also rotates together with it. As the rotational force of the outer cap F causes the inner cap D to rotate along with it, the screw-free connection between the inner cap D and the mouth 1 of the container body A causes the cap body C to rise, and finally, the container becomes a coating container with the cap body C removed.

[0037] Furthermore, when the cap body C rises from the mouth 1 of the container body A by unscrewing, the lower surface of the pressing wall 38 of the pressing portion E, which had been pressing down on the upper surface of the stopper projection 14 of the stopper portion 13 of the valve body B2 of the coating member B before the cap body C came off, also rises along with the cap body C. As shown in Figure 2(a), the elasticity of the spring cylinder portion 12 of the valve body B2 biases the stopper portion 13 to tightly seal against the opening 6 of the partition wall 7 of the frame body B1, closing the opening 6 of the partition wall 7, and the coating member B seals the inside of the container body A.

[0038] When applying the liquid contents from the container body A, as shown in Figure 2(b), the application container is inverted, and the tip of the stopper projection 14 of the valve body B2 of the application member B is pressed against the desired application surface T. This pushes in the stopper portion 13, releasing the tight seal between the periphery of the opening 6 of the frame body B1 and the sealing surface 15 of the stopper 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 projection 14 of the valve body B2 against the coating surface T is released, the elasticity of the spring cylinder portion 12 of the valve body B2 biases the plug portion 13 against the opening 6 of the partition wall 7 of the frame body B1, causing it to seal tightly and block the opening 6 of the partition wall 7, thereby stopping the flow of the liquid contents. The coating member B can be applied thinly and evenly to the coating surface T by repeatedly pressing the stopper portion 13 against the coating surface T to cause the liquid to seep out, and then stopping the seeping of the liquid by releasing the pressure.

[0039] In this embodiment, the coating member B is biased by the elasticity of the spring cylinder portion 12 of the valve body B2, so when the plug portion 13 is pressed, it acts as a cushion and can gently contact the coating surface T. Furthermore, by repeatedly pressing the plug portion 13, a massage effect can also be expected. Furthermore, by using a felt or brush-like material with some shape retention as the tip of the stopper projection 14 of the stopper portion 13 of the coating member B, and by making it possible to press it down from above, the range of applications for coating can be expanded. In addition, a coating body (such as a sponge-like material) may be provided on the upper part of the stopper portion 13 to apply the liquid contents. Furthermore, if a coating is provided on the upper part of the stopper portion 13, the outer cap F of the cap body C will press down on the stopper portion 13 of the valve body B2 via the coating.

[0040] After applying the liquid contents inside container body A, when closing the lid again with cap body C, place cap body C over the opening 1 of container body A, where the application member B is set, and screw it in while rotating it in the closing direction. In this case, when the outer cap F rotates in the closing direction, the tip of the locking projection 53 of the outer cap F disengages from the open-side locking portion 31a in the rotating groove 30 of the non-rotating inner cap D, and slides against the rotatable portion 31c, causing the outer cap F to rotate freely in the closing direction. When the outer cap F rotates freely, the tip of the pressing projection 56 of the rotating pressing cylinder portion 48 of the outer cap F detaches from the open-side high bottom portion 41a of the cam recess 40 of the pressing cylinder portion 39 of the pressing portion E and comes into contact with the inclined bottom portion 41c. Due to the inclination of the inclined bottom portion 41c and the restoring force of the thin-walled piece 37, the pressing portion E rises axially inside the inner cap D.

[0041] Furthermore, when the outer cap F is rotated in the closing direction, as shown in Figure 5, the lower surface of the push-down projection 56 comes into contact with the upper surface of the closed-side lower bottom portion 41b of the cam recess 40, releasing the push-down of the push-down portion E against the inner cap D, and the stopper projection 14 of the coating member B is no longer pressed down. The tip of the locking projection 53 of the outer cap F engages with the closed-side locking portion 31b in the rotating groove 30 of the inner cap D, and the side surface of the locking projection 53 comes into contact with the closed-side end 30b surface. Also, the side surface of the push-down projection 56 of the rotating push cylinder portion 48 of the outer cap F comes into contact with the closed-side end 40b surface in the cam recess 40 of the push-down portion E. As the outer cap F is rotated further, the inner cap D also rotates together, and the screwing progresses, so that as shown in Figure 1, the cap body C is screwed onto the container body A and the lid is closed.

[0042] In this embodiment, the pressing portion E is connected to the inner cap D by a connecting ring 36 connected inward from the inner edge opening 23a of the upper wall 23 of the inner cap D via a connecting piece 35, and a disc-shaped pressing wall 38 connected inward from the inner edge of the connecting ring 36 via a deformable thin-walled piece 37. Therefore, even if the thin-walled piece 37 is fully extended by the pressing of the pressing cylinder portion 39 and the pressing wall 38, the connecting ring 36 will be pulled down by the thin-walled piece 37, causing the connecting piece 35 to deform, thus creating a margin in the pressing width. Furthermore, the restoring force of the connecting piece 35 is added to the thin-walled piece 37, constantly applying a force to return the pressing portion E to its original position relative to the inner cap D. When the pressing by the outer cap F is released, the pressing portion E can be quickly restored to its original state.

[0043] (Example 2) Next, Example 2, in which the shape of the pressing portion E in Example 1 is changed, will be described with reference to the figure. In the following description, components identical to those in Example 1 will be denoted by the same reference numerals, and modified components will be denoted by new reference numerals, with the differences being the main focus of the explanation.

[0044] In Figure 7, A is the container body, B is the coating member attached to the opening 1 of the container body A, and Ca is a cap body that is screwed onto the opening 1 of the container body A so as to be openable and closable and covers the coating member B. The cap body Ca consists of an inner cap D that covers the coating member B from the inside and is screwed onto the mouth 1 of the container body A, a pressing portion Ea connected to the inside of the inner cap D and capable of being deformed by being pressed down in the axial direction relative to the inner cap D, and an outer cap F that covers the outside of the inner cap D, is mounted so as to be able to rotate freely within a predetermined angular range α relative to the inner cap D, and presses down the pressing portion Ea in the axial direction.

[0045] The pressing section Ea consists of multiple base sections 60 arranged at equal intervals (three in this embodiment at 120° intervals) from the inner edge opening 23a of the upper wall 23 of the inner cap D, valve bands 61 connected from the inner circumference center of each base section 60, extending and deforming toward the central disc-shaped pressing wall 38 while creating a gap from the inner edge opening 23a, thereby allowing the pressing wall 38 to spring-deform in the axial direction, and a pressing cylinder section 39 erected on the outer edge of the pressing wall 38, with a cam recess 40 recessed in the pressing cylinder section 39. Here, the valve band 61 constitutes a deformable connecting portion.

[0046] Each valve band 61 is formed from an outer projection 61a extending inward from the center of the inner circumference of the base portion 60, an arc-shaped piece 61b extending in an arc shape from the tip of the outer projection 61a to either the left or right (to the right in this embodiment), and an inner projection 61c extending toward the push-down wall 38 from the inside of the end of the arc-shaped piece 61b opposite to the outer projection 61a. The deformation, such as twisting, of each part of the valve band 61 causes the central push-down wall 38 and the push-down cylinder portion 39 to move downward and upward in a balanced manner.

[0047] In this embodiment, the pressing portion Ea is configured such that the three valve bands 61 deform and return to their original state in a balanced manner. Therefore, the pressing wall 38 and the pressing cylinder portion 39 of the pressing portion Ea can be lowered and raised axially relative to the inner cap D by the rotation of the outer cap F. Furthermore, since internal pressure can be released through the gap formed between the inner edge opening 23a of the upper wall 23 of the inner cap D and the downward wall 38, the cap body Ca will not detach from the opening 1 of the container body A even if the pressure inside the inner cap D rises. Other effects and benefits are the same as in Example 1.

[0048] (Example 3) Next, Example 3, in which the shape of the pressing portion E in Example 1 is changed, will be described with reference to the figure. In the following description, components identical to those in Example 1 will be denoted by the same reference numerals, and modified components will be denoted by new reference numerals, with the differences being the main focus of the explanation.

[0049] In Figure 8, A is the container body, B is the coating member attached to the opening 1 of the container body A, and Cb is a cap body that is screwed onto the opening 1 of the container body A so as to be openable and closable and covers the coating member B. The cap body Cb consists of an inner cap D that covers the coating member B from the inside and is screwed onto the mouth 1 of the container body A, a pressing portion Eb connected to the inside of the inner cap D and deformable by being pressed down in the axial direction relative to the inner cap D, and an outer cap F that covers the outside of the inner cap D, is mounted so as to be able to rotate freely within a predetermined angular range α relative to the inner cap D, and presses down the pressing portion Eb in the axial direction.

[0050] The pressing section Eb is connected to the inner edge opening 23a of the upper wall 23 of the inner cap D and consists of a bellows deformable wall 65 made of a deformable thin material, a disc-shaped pressing section 38 connected to the inner edge of the bellows deformable wall 65, and a pressing section 39 erected on the outer edge of the pressing section 38, with a cam recess 40 recessed in the pressing section 39. Here, the bellows-shaped deformed wall 65 constitutes a deformed connecting section.

[0051] The bellows-shaped deformable wall 65 is connected to the inner edge opening 23a and consists of a mountain wall section 65a that is folded upwards, and a valley wall section 65b that is connected to the outer edge of the downward wall 38 and is folded downwards.

[0052] In this embodiment, the pressing portion Eb is configured to deform and return to its original shape by a deformable thin-walled bellows deformation wall 65. Therefore, the pressing wall 38 and the pressing cylinder portion 39 of the pressing portion Eb can be lowered and raised axially relative to the inner cap D by the rotation of the outer cap F. Furthermore, since the bellows-type deformable wall 65 is deformable, even if the pressure inside the inner cap D rises, the internal pressure can be adjusted simply by the bellows-type deformable wall 65 deforming and expanding, and the cap body Cb will not detach from the mouth 1 of the container body A. Other effects and benefits are the same as in Example 1. [Industrial applicability]

[0053] The coating container of the present invention consists of a coating member attached to the mouth of the container body, an inner cap, a push-down part connected to the inside of the inner cap, and an outer cap, which is screwed onto the mouth of the container body so as to be openable and closable and covers the coating member. By rotating the outer cap of the closed cap body in the opening direction relative to the inner cap, the push-down part slightly opens the coating member before the opening begins, releasing the pressure inside the container body, thereby preventing the contents from spraying out after opening. This coating container is particularly suitable as a coating container for cosmetics, pharmaceuticals, etc., where the internal pressure may rise. [Explanation of symbols]
