Abstract
Description
[Technical Field]
[0001] The present invention relates to an application container. [Background technology]
[0002] For example, Patent Document 1 describes an application container that includes a container body having an inner container in which the contents are stored and an outer container in which the inner container is placed, and an inner stopper attached to the mouth of the container body. The inner plug has a cylindrical holder with a communication port that communicates with the inside of the inner container, and a rotary applicator that is rotatably held within the cylindrical holder. The inner container is deformed by shrinking its volume as the contents decrease, and the outer container is deformable by squeezing. An air intake hole is formed between the outer container and the inner container to draw in outside air. In this applicator container, when the outer container is squeezed, the inner container deforms together with the outer container, reducing its volume, causing the internal pressure of the inner container to increase, and the contents in the inner container flow into the cylindrical holding part through the communication port.Then, by pressing the rotating applicator against the part to be coated and rotating it, the contents in the cylindrical holding part are coated onto the part to be coated.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-209973 Summary of the Invention [Problem to be solved by the invention]
[0004] With the conventional applicator containers described above, it is difficult to dispense a small amount of the contents from the inner container by slightly squeezing and deforming the outer container. Therefore, when the contents are medicine, it is often required to apply a small amount to the affected area, but it is difficult to meet such needs, and there have been issues with operability. On the other hand, in the case of a container body with an inner container that shrinks and deforms as the contents decrease, such as a delaminating bottle, the inflow of outside air into the inner container is suppressed, thereby suppressing oxidation of the contents inside the inner container and providing a high added value of maintaining the quality of the contents. Therefore, there is still a need for this high added value.
[0005] The present invention provides an application container that maintains the quality of the contents and allows application of small amounts of liquid. [Means for solving the problem]
[0006] An applicator container according to one aspect of the present invention comprises an inner container that accommodates contents and undergoes volume reduction deformation as the contents decrease, and an outer container in which the inner container is housed and an air intake hole is provided between the inner container and the outer container, an inner plug member that is attached to the mouth of the container body and has a communication hole that communicates with the inside of the inner container, a check valve that is removably fitted upward against the opening periphery of the communication hole in the inner plug member, a discharge member that covers the communication hole from above and has a discharge hole for the contents, and an applicator stopper provided between the inner plug member and the discharge member, wherein the applicator stopper is The container is provided with an elastic cylindrical portion formed in a topped cylindrical shape, which covers the communication hole from above and defines a storage chamber between itself and the inner stopper member, and an application portion provided at the top of the elastic cylindrical portion and protruding upward from the discharge member through the discharge hole, wherein a slit is formed at the top of the elastic cylindrical portion, which blocks communication between the storage chamber and the discharge hole and expands when the elastic cylindrical portion is compressed and deformed downward to communicate between the storage chamber and the discharge hole, and the portion of the top of the elastic cylindrical portion where the slit is formed abuts or is close to the discharge member, and the storage chamber is formed in a flat shape whose vertical size is equal to or smaller than the radial size intersecting the container axis when viewed from the vertical direction.
[0007] According to the above aspect, when the applicator portion of the applicator stopper is pressed against the part to be applied, the applicator portion is pushed into the storage chamber through the discharge hole, compressing and deforming the elastic cylindrical portion in the vertical direction, widening the slit, and connecting the storage chamber and the discharge hole. At this time, the storage chamber is pressurized due to the compressive deformation of the elastic cylindrical portion. If contents are stored in the storage chamber, the contents are discharged through the slit and the discharge hole into the part to be applied, and the check valve maintains the communication hole in a closed state. Therefore, with communication between the inner container and the storage chamber through the communication hole blocked, only the amount of contents stored in the storage chamber can be applied to the part to be applied. As a result, it is possible to eject and apply the amount of contents stored in the storage chamber by pressing the application part against the part to be applied, without having to squeeze and deform the outer container as in the past, and even small amounts of contents can be applied stably. When the pressure of the applicator part against the part to be applied is released, the elastic cylindrical part deforms to restore its original shape, closing the slit and blocking communication between the reservoir chamber and the discharge hole. At this time, the reservoir chamber becomes under negative pressure, the check valve moves upward away from the communication hole, and the inner container and the reservoir chamber communicate through the communication hole. The contents in the inner container flow into the reservoir chamber through the communication hole and are stored there. In this case, when the inner container undergoes volume reduction and deformation as the contents decrease, negative pressure is created between the inner and outer containers, and outside air is drawn into the gap between the inner and outer containers through the intake holes in the outer container. This keeps the inner container in a volume reduction state, prevents outside air from entering the inner container, and prevents oxidation of the contents inside the inner container, providing the added value of maintaining the quality of the contents.
[0008] The part of the top of the elastic cylindrical part where the slit is formed (hereinafter referred to as the slit part) is in contact with or close to the discharge member, so even if the contents try to open the check valve and flow into the storage chamber through the communication hole due to, for example, their own weight or the internal pressure of the inner container, the slit part is in close contact with the discharge member, preventing communication between the storage chamber and the discharge hole through the slit. Therefore, the amount of contents stored in the storage chamber can be discharged only when the applicator part is pressed against the part to be applied. Since the storage chamber is formed in a flat shape whose vertical size is equal to or smaller than its radial size, when the applicator part is pressed against the part to be applied, the internal volume of the storage chamber can be significantly reduced without significantly compressing and deforming the elastic cylindrical part in the vertical direction, and when the elastic cylindrical part returns to its original shape, a large amount of the contents in the inner container can flow into the storage chamber. This reduces the number of times the applicator part is pressed against the part to be applied and the number of times it is released.
[0009] A regulating protrusion protruding upward may be provided on the peripheral edge of the opening of the discharge hole in the discharge member, and the amount by which the application portion protrudes upward from the regulating protrusion may be smaller than the vertical distance between the top of the elastic cylindrical portion and the check valve.
[0010] A restricting protrusion that protrudes upward is provided on the periphery of the opening of the discharge hole in the discharge member, so that when the applicator part is pressed against the part to be applied, the restricting protrusion abuts against the part to be applied, preventing the applicator part from being pushed further into the storage chamber. At this time, the amount by which the applicator part protrudes upward from the restricting protrusion is smaller than the vertical distance between the top of the elastic cylindrical part and the check valve, so that when the applicator part is pressed against the part to be applied, the top of the elastic cylindrical part does not press the check valve downward, and it is possible to prevent the check valve from becoming difficult to move upward away from the communicating hole when negative pressure is created in the storage chamber. [Effects of the Invention]
[0011] According to the above aspect of the present invention, it is possible to provide an application container that maintains the quality of the content and allows application of a small amount of content. [Brief explanation of the drawings]

[0013] Hereinafter, a first embodiment of an application container according to the present invention will be described with reference to the drawings. 1, the application container 1 of this embodiment includes a container body W, an inner plug member 11, a check valve 12, a discharge member 13, an application plug 14, an application member 15, a fixing ring 16, and a cap 17. The application member 15, the fixing ring 16, and the cap 17 do not necessarily have to be provided.
[0014] The container body W is formed in a cylindrical shape with a bottom. Hereinafter, the central axis of the container body W will be referred to as the container axis O, the side of the mouth W1 of the container body W in the direction along the container axis O will be referred to as the upper side, the bottom side of the container body W in the direction along the container axis O will be referred to as the lower side, and the direction along the container axis O will be referred to as the up-down direction. When viewed from the up-down direction, the direction intersecting the container axis O will be referred to as the radial direction, and the direction going around the container axis O will be referred to as the circumferential direction.
[0015] (Container body and cap) The container body W includes an inner container W2 that accommodates contents and undergoes volume-reducing deformation (shrinkage deformation) as the contents decrease, and an outer container W3 that houses the inner container W2. The container body W is a delaminating container (delamination bottle) in which the inner container W2 is peelably laminated on the inner surface of the outer container W3. The outer container W3 is formed to have a constant rigidity throughout, and the body of the outer container W3 is resistant to deformation even when pressed radially inward. The outer container W3 is provided with an air intake hole (not shown) that introduces outside air between it and the inner container W2. The air intake hole is provided, for example, in the bottom or opening of the outer container W3. A slit in the outer container W3 at a pinch-off portion provided at the bottom of the container body W may also be used as the air intake hole. A cylindrical cap 17 with a top is detachably screwed onto the opening of the outer container W3.
[0016] (Inner plug component) The inner plug member 11 is attached to the mouth W1 of the container body W and has a communication hole 21 that communicates with the inside of the inner container W2. The inner plug member 11 is formed in a cylindrical shape with a top, having an inner plug top wall 22 and an inner plug peripheral wall 23, and is disposed coaxially with the container axis O. A communication hole 21 that passes through in the vertical direction is formed in the inside plug top wall 22. The communication hole 21 is disposed coaxially with the axis O of the container. The inner plug peripheral wall 23 is formed in a double-cylinder shape having an outer cylinder 23a and an inner cylinder 23b. The lower ends of the outer cylinder 23a and the inner cylinder 23b are connected to each other. The outer cylinder 23a is tightly fitted into the mouth W1 of the container body W. A flange portion 23c is formed at the upper end of the outer cylinder 23a, protruding radially outward and positioned at the upper opening edge of the mouth W1.
[0017] (non-return valve) The check valve 12 includes a valve body 24, a fixed portion 25, and an elastic connecting piece 26, and closes the communication hole 21 in an openable manner. The valve body 24 is formed in a flat plate shape with its front and back surfaces facing up and down, and is in close contact with the opening periphery of the communication hole 21 on the upper surface of the inner plug top wall 22 of the inner plug member 11 so as to be able to move upward and away from it. The fixing portion 25 is formed in a cylindrical shape and is fitted onto the upper end of the inner plug peripheral wall 23 of the inner plug member 11 and fixed thereto. The elastic connecting pieces 26 radially connect the outer peripheral surface of the valve body 24 and the upper end of the inner peripheral surface of the fixing portion 25. Three elastic connecting pieces 26 are provided at equal intervals in the circumferential direction. The check valve 12 constitutes a so-called three-point valve.
[0018] (Discharge member) The discharge member 13 includes a covering portion 31 and a mounting portion 32 . The mounting portion 32 is formed in a cylindrical shape and is fitted and fixed within the upper end of the outer cylinder 23a of the inside plug peripheral wall 23. The upper part of the mounting portion 32 protrudes upward from the outer cylinder 23a. The covering portion 31 covers the communication hole 21 from above and has a discharge hole 28 for the contents. The covering portion 31 protrudes radially inward from the vertical middle portion of the attachment portion 32. The covering portion 31 is formed in a plate shape with its front and back surfaces facing vertically, and extends upward as it moves radially inward. A restricting protrusion 33 protruding upward is provided on the upper surface of the covering portion 31 around the opening periphery of the discharge hole 28. The restricting protrusion 33 is formed in a cylindrical shape. The upper opening edges of the restricting protrusion 33 and the mounting portion 32 are located at the same vertical position. The restricting protrusion 33 and the discharge hole 28 are arranged coaxially with the container axis O. The restricting projection 33 is not limited to a cylindrical shape extending continuously over the entire circumferential length, but may be, for example, a plurality of plate bodies provided at intervals in the circumferential direction.
[0019] (application plug) Applicator plug 14 includes an elastic cylindrical portion 35, an applicator portion 36, and a plug fixing portion 37, and is provided between inner plug member 11 and discharge member 13. Applicator plug 14 is formed from a soft material such as silicone rubber or elastomer.
[0020] The elastic cylindrical portion 35 is formed in a topped cylindrical shape having an elastic top wall (top) 38 and an elastic peripheral wall 39, and is disposed coaxially with the container axis O. The elastic cylindrical portion 35 covers the communication hole 21 and the valve body 24 from above. Between the elastic cylindrical portion 35 and the inner plug top wall 22 of the inner plug member 11, a storage chamber X that can communicate with the communication hole 21 is defined. The elastic top wall 38 is formed in a flat plate shape with its front and back surfaces facing up and down. The elastic peripheral wall 39 extends radially inward as it extends upward. The applicator 36 is provided on the elastic top wall 38 and protrudes upward from the covering portion 31 through the discharge hole 28. The applicator 36 is formed in a rod shape extending in the vertical direction and is disposed coaxially with the container axis O. The upper end surface of the applicator 36 is located above the upper opening edges of the restricting projection 33 and the mounting portion 32. The amount by which the applicator 36 protrudes upward from the restricting projection 33 is smaller than the vertical distance between the lower surface of the elastic top wall 38 and the upper surface of the valve body 24 of the check valve 12. The plug fixing portion 37 is formed in a cylindrical shape extending in the vertical direction. The plug fixing portion 37 extends downward from the lower end opening edge of the elastic cylindrical portion 35 and is inserted and fixed between the inner circumferential surface of the outer tube 23a and the outer circumferential surface of the inner tube 23b of the inner plug peripheral wall 23. The thickness of the plug fixing portion 37 is thicker than the thickness of the elastic cylindrical portion 35. An upward-facing step is formed on the outer circumferential surface of the plug fixing portion 37, and the lower end opening edge of the mounting portion 32 of the discharge member 13 abuts against this step.
[0021] The elastic top wall 38 is formed with slits 41 that block communication between the reservoir chamber X and the discharge hole 28 and expand when the elastic tubular portion 35 is compressed and deformed downward to allow communication between the reservoir chamber X and the discharge hole 28. As shown in FIG. 2 , multiple slits 41 are provided at intervals in the circumferential direction so as to surround the applicator portion 36 from the radial outside. Four slits 41 are provided at equal intervals in the circumferential direction. The slits 41 extend in a direction perpendicular to the radial direction when viewed from the top and bottom. The slits 41 face the lower surface of the covering portion 31 of the discharge member 13 in the vertical direction. The portion of the elastic top wall 38 where the slits 41 are formed is in contact with or close to the discharge member 13. In the illustrated example, the elastic top wall 38 and the elastic peripheral wall 39 are in contact with or close to the lower surface of the covering portion 31 of the discharge member 13.
[0022] The storage chamber X is formed in a flat shape whose vertical size is equal to or smaller than its radial size. The vertical distance between the lower surface of the elastic top wall 38 and the upper surface of the valve body 24 of the check valve 12 is equal to or smaller than the radial size of the lower end of the storage chamber X. For example, the vertical size of the storage chamber X is 26% to 80% of the radial size of the storage chamber X. In the illustrated example, the vertical distance between the lower surface of the elastic top wall 38 and the upper surface of the valve body 24 of the check valve 12 is approximately 3.2 mm, the radial size of the lower end of the storage chamber X is approximately 10.7 mm, and the vertical distance between the lower surface of the elastic top wall 38 and the upper surface of the valve body 24 of the check valve 12 is approximately 29.9% of the radial size of the lower end of the storage chamber X. The storage chamber X has a circular shape when viewed from above and below, and the diameter of the storage chamber X decreases as it goes upward.
[0023] (Applicator and fixing ring) The applicator member 15 is formed of an elastically deformable porous material such as a sponge, etc. The applicator member 15 covers the discharge member 13 and the applicator plug 14 from above. The fixing ring 16 is fitted onto and fixed to the flange portion 23c of the inside plug peripheral wall 23 and the mounting portion 32 of the discharge member 13. The fixing ring 16 and the outer peripheral surface of the mounting portion 32 clamp and fix the outer peripheral edge portion of the applicator member 15 in the radial direction over the entire circumference.
[0024] (Action of application container) Next, a description will be given of the operation of the application container 1 configured as above. It is assumed that the content is stored in the storage chamber X.
[0025] First, the cap 17 is removed from the opening W1 to expose the applicator 15. At this time, the slit 41 of the elastic tubular portion 35 is closed, and the portion of the elastic top wall 38 where the slit 41 is formed (hereinafter referred to as the slit portion) is in contact with or close to the discharge member 13. Therefore, when the applicator container 1 is in an inverted position, even if the weight of the contents of the storage chamber X is applied to the elastic top wall 38, the slit portion is in close contact with the underside of the covering portion 31 of the discharge member 13, so that the contents of the storage chamber X are prevented from leaking out of the storage chamber X through the slit 41.
[0026] Next, as shown in FIG. 3, with the applicator container 1 in an inverted position, the applicator portion 36 of the applicator stopper 14 is pressed against the area to be coated via the applicator member 15. This pushes the applicator portion 36 toward the reservoir X through the discharge hole 28, compressing and deforming the elastic tubular portion 35 in the vertical direction, widening the slit 41, and connecting the reservoir X to the discharge hole 28. As this occurs, the reservoir X is pressurized due to the compressive deformation of the elastic tubular portion 35, causing the contents of the reservoir X to be discharged through the slit 41 and the discharge hole 28 into the area to be coated. Furthermore, the check valve 12 maintains the communication hole 21 in a closed state. Therefore, with communication between the inner container W2 and the reservoir X through the communication hole 21 blocked, only the amount of contents stored in the reservoir X can be discharged to the area to be coated. The contents discharged to the area to be coated are then applied to the area by, for example, rubbing the applicator portion 36 and the applicator member 15 against the area to be coated.
[0027] 4, when the pressing of the applicator part 36 against the part to be applied is released, the elastic tubular part 35 undergoes restoring deformation, causing the applicator part 36 to protrude from the discharge hole 28 and undergo restoration displacement, and the slit 41 is closed, blocking communication between the reservoir chamber X and the discharge hole 28. Consequently, negative pressure is created within the reservoir chamber X, elastically deforming the elastic connecting piece 26 and causing the valve body 24 to move away from the inner plug top wall 22 and opening the communication hole 21. As a result, the interior of the inner container W2 and the reservoir chamber X are connected through the communication hole 21, and the contents within the inner container W2 flow into the reservoir chamber X through the communication hole 21 and are stored therein. At this time, when the inner container W2 undergoes volume reduction deformation due to the decrease in the contents, a negative pressure is created between the inner container W2 and the outer container W3, and outside air is drawn into the gap between the inner container W2 and the outer container W3 through the intake hole of the outer container W2, thereby maintaining the inner container W2 in its volume-reduced and deformed state.
[0028] As described above, according to the application container 1 of this embodiment, it is possible to eject and apply the amount of contents stored in the storage chamber X by pressing the application section 36 against the part to be applied, without having to squeeze and deform the outer container W3 as in the conventional case, and even a small amount of contents can be applied stably. Even if the contents of the inner container W2 flow into the storage chamber X, the inner container W2 is maintained in a volume-reduced and deformed state, and outside air is prevented from entering the inner container W2, making it possible to prevent oxidation of the contents in the inner container W2, thereby providing the added value of maintaining the quality of the contents.
[0029] The slit portion of the elastic top wall 38 where the slit 41 is formed is in contact with or close to the discharge member 13, so even if the contents try to open the check valve 12 and flow into the storage chamber X through the communication hole 21 due to, for example, its own weight or the internal pressure of the inner container W2, the slit portion is in close contact with the underside of the covering part 31 of the discharge member 13, preventing communication between the storage chamber X and the discharge hole 28 through the slit 41. Therefore, the amount of contents stored in the storage chamber X can be discharged and applied only when the application part 36 is pressed against the part to be applied.
[0030] Because the storage chamber X is formed in a flat shape whose vertical size is equal to or smaller than its radial size, when the applicator part 36 is pressed against the part to be applied, it is possible to greatly reduce the internal volume of the storage chamber X without significantly compressing and deforming the elastic cylindrical part 35 in the vertical direction, and when the elastic cylindrical part 35 is restored and deformed, a large amount of the contents in the inner container W2 can flow into the storage chamber X. This reduces the number of times the applicator part 36 is pressed against the part to be applied and the number of times it is released, which are required until the contents in the inner container W2 are filled into the storage chamber X.
[0031] Since a restricting protrusion 33 protruding upward is provided on the periphery of the opening of discharge hole 28 in discharge member 13, when applicator portion 36 is pressed against the part to be applied, restricting protrusion 33 abuts against the part to be applied, thereby restricting applicator portion 36 from being pushed further into reservoir chamber X. At this time, the amount by which applicator portion 36 protrudes upward from restricting protrusion 33 is smaller than the vertical distance between the lower surface of elastic top wall 38 and the upper surface of valve body 24 of check valve 12. Therefore, when applicator portion 36 is pressed against the part to be applied, elastic top wall 38 does not press the upper surface of valve body 24 downward, and it is possible to prevent valve body 24 from being difficult to move upward from communicating hole 21 when reservoir chamber X becomes negative pressure.
[0032] Next, an application container 2 according to a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted, with only the differences being described.
[0033] In the application container 2 of this embodiment, the check valve 12 constitutes a so-called single-point valve, the middle plug peripheral wall 23 is formed in a single cylindrical shape consisting of the outer tube 23a but not the inner tube 23b, and the plug fixing part 37 has a flange part that protrudes radially outward from the lower end of the elastic cylindrical part 35, and this flange part is sandwiched and fixed in the vertical direction between the lower end opening edge of the mounting part 32 in the discharge member 13 and the upper surface of the middle plug top wall 22. The check valve 12 does not have a fixing portion 25, but has one elastic connecting piece 26, and the valve body 24 is connected to the plug fixing portion 37 via the elastic connecting piece 26. The valve body 24 protrudes radially inward from the flange portion of the plug fixing portion 37. The elastic connecting piece 26 is formed thin and is formed to be elastically deformable in the vertical direction. The check valve 12 is formed integrally with the applicator plug 14. During injection molding, the valve body 24 is formed in a position where it protrudes downward from the flange portion of the plug fixing portion 37, as shown by the two-dot chain line in Figure 5. The application container 2 of this embodiment also provides the same effects as the application container 1 of the first embodiment.
[0034] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
[0035] For example, the restricting protrusion 33 may not be provided. The container body W may have a configuration in which a gap is provided between the inner container W2 and the outer container W3, for example. The body of the outer container W3 may be formed to be deformable by squeezing. [Explanation of symbols]
