Description

[Technical Field]

[0001] The present invention relates to a metered dispense container. [Background technology]

[0002] Conventionally, there has been known a discharge device in which a syringe-type discharge tool is detachably attached to a container with a lid, as shown in Patent Document 1. This discharge tool is provided with an auxiliary check valve at its lower end opening. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-249110 Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the above-mentioned conventional dispensing tool is provided with an auxiliary check valve at the bottom opening, it is possible to prevent dripping from the bottom opening when the tool is lifted from the lidded container. However, the provision of the auxiliary check valve increases the flow resistance, and it is necessary to operate the syringe with a strong force when dispensing the contents.

[0005] The present invention was made in consideration of these circumstances, and its purpose is to provide a measuring and dispensing container that allows the measuring member to be operated with light force and that can prevent liquid from dripping from the measuring member when it is removed from the container body. [Means for solving the problem]

[0006] (1) A measuring and dispensing container according to the present invention comprises a container body in which contents are accommodated, and a measuring member detachably attached to the container body and for measuring and dispensing the contents drawn up from the container body, the measuring member comprising a cylinder having a measuring chamber for the contents formed therein, a piston slidably fitted into the cylinder, an operating member protruding upward from an upper end opening of the cylinder and moving vertically relative to the cylinder together with the piston, a pouring outlet protruding downward from a lower end opening of the cylinder, and a communication hole for communicating the pouring outlet with the measuring chamber. and a dispensing tube that moves up and down relative to the cylinder together with the piston and the operating member, and whose lower end, on which the dispensing outlet is formed, is detachably engaged with the container body; and an elastic member that is provided between the cylinder and the operating member, and that elastically deforms the operating member downward relative to the cylinder side by the engagement between the dispensing tube and the container body when the cylinder is pulled upward, and that restores the upward deformation of the operating member side when the engagement between the dispensing tube and the container body is released, thereby increasing the volume of the measuring chamber.

[0007] According to the metered dispensing container of the present invention, when the cylinder is raised to remove the measuring member from the container body, the lower end of the dispensing tube is engaged with the container body, causing the cylinder to rise ahead of the dispensing tube, piston, and operating member until this engagement is released. An elastic member is provided between the cylinder and the operating member, and when the cylinder rises ahead, the operating member side of the elastic member elastically deforms downward relative to the cylinder side. When the engagement between the lower end of the dispensing tube and the container body is released by further raising the cylinder, the operating member side of the elastic member restores its original shape, causing the dispensing tube, piston, and operating member to rise relative to the cylinder. This increases the volume of the measuring chamber inside the cylinder, and the contents corresponding to this increase in volume are sucked upward through the dispensing tube's outlet, resulting in a so-called suck-back effect. This reduces dripping from the dispensing tube's outlet. Furthermore, this configuration eliminates the need for a check valve at the dispensing tube's outlet, allowing the operating member to be operated with less force than if a check valve were installed.

[0008] (2) The outer peripheral surface of the operating member may have a protruding portion that protrudes radially outward, and the elastic member may include a fixed portion fixed to the cylinder, a contact portion that contacts the protruding portion from below, and a groove portion formed between the fixed portion and the contact portion and opening upward.

[0009] In this case, when the cylinder rises ahead of the operating member, the abutment portion of the elastic member that abuts from below against the protrusion of the operating member elastically deforms downward relative to the fixed portion of the elastic member that is fixed to the cylinder. A groove that opens upward is provided between the fixed portion and the abutment portion, and by partially reducing the rigidity of the elastic member between the fixed portion and the abutment portion, it is possible to make it easier for the abutment portion to elastically deform downward relative to the fixed portion.

[0010] (3) The container body may include an attachment tube to which the measuring member is detachably attached, and the attachment tube may include a first tubular portion with which the lower end of the dispensing tube engages, a second tubular portion connected to the upper end of the first tubular portion and accommodating the peripheral wall of the cylinder, and a communication flow path that passes through the attachment tube and connects the inside of the attachment tube to the inside of the container body.

[0011] In this case, when the measuring member is removed from the container body, outside air flows into the container body through the communication flow path of the attachment tube, thereby releasing the negative pressure inside the container body caused by the suction of the contents of the container body. Also, if the container body falls over, the contents that have flowed into the attachment tube can be returned to the container body through the communication flow path of the attachment tube. [Effects of the Invention]

[0012] According to the metering dispensing container of the present invention, the metering member can be operated with a light force, and dripping from the metering member when it is removed from the container body can be suppressed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, a measuring and dispensing container according to one embodiment will be described with reference to the drawings.

[0015] As shown in Fig. 1, the metered dispensing container 1 comprises a cylindrical container body 2 with a bottom in which the contents are accommodated, and a syringe-type measuring member 3 that is detachably attached to the container body 2. Examples of the contents of the container body 2 include medicines and liquid cosmetics to be applied (discharged) to the human body (skin).

[0016] The container body 2 is equipped with a cap member 10 to which the measuring member 3 is detachably attached. The cap member 10 is attached to the mouth 2a of the container body 2. The measuring member 3 is attached to a threaded tube 14 of the cap member 10, which will be described later. The measuring member 3 may also be attached directly to the mouth 2a of the container body 2. The measuring member 3 is equipped with a cylinder 20 that forms a measuring chamber 100, a piston 30 that slides within the cylinder 20, an operating member 40 that moves the piston 30 up and down, a dispensing tube 50 that sucks up and dispenses the contents, and an elastic member 60 that is provided between the cylinder 20 and the operating member 40.

[0017] In this embodiment, the central axes of the container body 2 and the measuring member 3 are located on a common axis. Hereinafter, this common axis will be referred to as the container axis O, the side of the mouth 2a of the container body 2 along the container axial direction (the upper side in FIG. 1) will be referred to as the upper side, and the bottom side of the container body 2 along the container axial direction (the lower side in FIG. 1) will be referred to as the lower side. Furthermore, when viewed from the container axial 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.

[0018] 2, the cap member 10 includes a cap peripheral wall 11, a cap top wall 12, a sealing tube 13, a threaded tube 14, and an attachment tube 15. The cap peripheral wall 11 is attached to the outside of the mouth portion 2a of the container body 2. In this embodiment, a female thread formed on the inner peripheral surface of the cap peripheral wall 11 is threadedly engaged with a male thread formed on the outer peripheral surface of the mouth portion 2a.

[0019] The cap top wall 12 extends radially inward from the upper end of the cap peripheral wall 11 and is formed in a ring shape in a plan view. The sealing tube 13 is suspended downward from the underside of the cap top wall 12. The outer peripheral surface of the sealing tube 13 is in close contact with the inner peripheral surface of the mouth portion 2a. The threaded tube 14 extends upward from the inner edge of the cap top wall 12. A male thread is formed on the outer peripheral surface of the threaded tube 14. The inner surface at the upper end of the threaded tube 14 is in close contact with the outer peripheral surface of the peripheral wall of the cylinder 20 when the metering member 3 is attached, ensuring a seal.

[0020] The mounting tube 15 extends downward from the inner edge of the cap top wall 12. The mounting tube 15 includes a first tube portion 15A that engages with the lower end of the dispensing tube 50, and a second tube portion 15B that is connected to the upper end of the first tube portion 15A and that houses the peripheral wall of the cylinder 20. The upper end of the second tube portion 15B is connected to the lower end of the threaded tube 14.

[0021] The first cylindrical portion 15A has smaller inner and outer diameters than the second cylindrical portion 15B. The mounting tube 15 is formed as a multi-stage tube in which the diameters of the second cylindrical portion 15B and the first cylindrical portion 15A decrease in order. A step is formed between the first cylindrical portion 15A and the second cylindrical portion 15B. A communication flow path 16 that penetrates the step in the vertical direction and connects the inside of the mounting tube 15 to the inside of the container body 2 is formed in this step.

[0022] The lower end of the first cylindrical portion 15A is formed with a valve seat 17 on which the check valve 4 (ball valve) sits from above, and a restricting piece 18 that restricts the upward movement of the check valve 4 once it moves away from the valve seat 17. The valve seat 17 is formed into a tapered cylindrical shape whose inner circumferential surface decreases in diameter as it extends downward. The check valve 4 is disposed above the valve seat 17. The check valve 4 abuts against the inner circumferential surface of the valve seat 17 so as to be able to move upward and away from it.

[0023] When negative pressure is created inside the measuring chamber 100, the check valve 4 moves upward away from the valve seat 17, connecting the inside of the measuring chamber 100 to the inside of the container body 2. After the contents have been sucked up, the check valve 4 seats on the valve seat 17, and the inner circumferential surface of the valve seat 17 and the outer surface of the check valve 4 come into close contact to form a sealing surface. This prevents the sucked up contents from returning from inside the measuring chamber 100 to the inside of the container body 2. Note that if the measuring member 3 is used immediately after the contents have been sucked up, the check valve 4 may not be necessary.

[0024] The regulating piece 18 is disposed above the valve seat 17 and protrudes radially inward from the inner peripheral surface of the first cylindrical portion 15A. The regulating piece 18 is formed with a gap in the circumferential direction, so that the contents can pass up and down even when the check valve 4 is abutting against it from below. The upper surface of the regulating piece 18 serves as a receiving surface that receives the lower end surface of the pouring tube 50 engaged with the inside of the first cylindrical portion 15A. A fitting tube 19 is suspended below the valve seat 17. The upper end of the pipe 5 extending toward the bottom of the container body 2 is fitted into the fitting tube 19.

[0025] The cylinder 20 has a cylindrical peripheral wall extending in the vertical direction, and is housed inside the threaded tube 14 and the second tube portion 15B. The upper end of the cylinder 20 extends higher than the upper end of the threaded tube 14. A flange 21 extending radially outward is formed at the upper end of the cylinder 20. A surrounding tube 22 that surrounds the radially outer side of the threaded tube 14 is suspended downward from the underside of the flange 21.

[0026] A female thread is formed on the inner peripheral surface of the surrounding tube 22 to be threadedly engaged with a male thread formed on the outer peripheral surface of the threaded tube 14. When the surrounding tube 22 is rotated around the container axis O relative to the threaded tube 14, the measuring member 3 can be removed from the cap member 10 of the container body 2 and reattached to the cap member 10.

[0027] A sliding tube 23 is provided at the lower end of the cylinder 20. The sliding tube 23 forms the lower end opening of the cylinder 20, and has a diameter smaller than the inner and outer diameters of the peripheral wall of the cylinder 20 that forms the measuring chamber 100. A pouring tube 50 is inserted into the sliding tube 23 so as to be slidable in the vertical direction. The inner peripheral surface of the lower end of the sliding tube 23 is in close contact with the outer peripheral surface of the pouring tube 50, thereby forming a sealing surface.

[0028] The dispensing tube 50 has a lower end that protrudes downward from the lower end opening of the cylinder 20. A dispensing outlet 51 is formed at the lower end of the dispensing tube 50. A communication hole 52 that connects the dispensing outlet 51 to the measuring chamber 100 is formed in the peripheral wall of the dispensing tube 50, which is located inside the cylinder 20. The measuring chamber 100 is an annular space defined by the inner surface of the cylinder 20, the lower surface of the piston 30, and the outer surface of the dispensing tube 50. The communication hole 52 penetrates the peripheral wall of the dispensing tube 50 in the radial direction, connecting the inside of the measuring chamber 100 to the inside of the dispensing tube 50.

[0029] A partition is provided to close the inside of the dispensing tube 50 above the communication hole 52. A piston support portion 54 that protrudes radially outward is provided above the communication hole 52 on the outside of the dispensing tube 50. The piston support portion 54 is formed in an annular shape centered on the container axis O. A fitted portion 53 onto which the operating member 40 is fitted is provided at the upper end of the dispensing tube 50 above the piston support portion 54.

[0030] The piston 30 is slidably fitted into the cylinder 20. The piston 30 includes a fixed cylinder portion 31 supported by a piston support portion 54, and a sliding contact portion 32 extending radially outward from the upper end of the fixed cylinder portion 31 and coming into sliding contact with the inner circumferential surface of the cylinder 20. The fixed cylinder portion 31 is fixed vertically between the upper surface of the piston support portion 54 and the lower end surface of the operating member 40 that fits into the fitted portion 53.

[0031] The operating member 40 protrudes upward from the upper end opening of the cylinder 20. When the operating member 40 moves up and down, the piston 30 and the dispensing tube 50 move up and down. The operating member 40 is formed in a topped cylindrical shape and is fitted onto the fitted portion 53. A push-down wall 41 that extends radially outward around the entire circumference is provided at the top of the operating member 40. A through hole 41a that penetrates in the vertical direction is formed in the center of the push-down wall 41. The through hole 41a allows air inside the operating member 40 to escape to the outside when the operating member 40 is fitted onto the upper end of the dispensing tube 50.

[0032] The operating member 40 has a protrusion 42 protruding radially outward on its outer peripheral surface below the push-down wall 41. The protrusion 42 is formed in a semicircular shape protruding radially outward in a cross-sectional view. The protrusion 42 is formed in an annular shape along the circumferential direction of the outer peripheral surface of the operating member 40. Note that the protrusions 42 may be provided intermittently with gaps in the circumferential direction of the outer peripheral surface of the operating member 40, as long as they can abut against the elastic member 60 in the up-down direction.

[0033] The elastic member 60 is provided in an annular shape between the cylinder 20 and the operating member 40. The elastic member 60 includes a fixed portion 61 fixed to the cylinder 20, a contact portion 62 that contacts the protruding portion 42 from below, and a groove portion 63 that is formed between the fixed portion 61 and the contact portion 62 and opens upward. When viewed in cross section from one side in the radial direction, the elastic member 60 is formed in a U-shape that opens upward.

[0034] The fixed portion 61 is fitted through an undercut into the inner peripheral wall of the upper end opening of the cylinder 20. The upper end of the fixed portion 61 protrudes upward beyond the flange 21 of the cylinder 20. The protruding portion of the push-down wall 41 of the operating member 40 can abut against the upper end of the fixed portion 61 in the vertical direction. This makes it possible to avoid collision between the push-down wall 41 and the flange 21 when the operating member 40 is pressed downward.

[0035] The abutting portion 62 is in sliding contact with the outer wall surface of the pouring tube 50. The upper end of the abutting portion 62 is located lower than the upper end of the fixed portion 61. The outer peripheral surface of the upper end of the abutting portion 62 is formed in a semicircular shape that protrudes radially inward in a cross-sectional view. The groove portion 63 is formed deeper than the undercut fitting portion of the fixed portion 61 and the semicircular portion of the abutting portion 62. As shown in the enlarged view of FIG. 4, a plurality of ribs that connect the inner wall surface of the fixed portion 61 and the outer wall surface of the abutting portion 62 in the radial direction are provided at the bottom of the groove portion 63 at intervals in the circumferential direction.

[0036] The abutment portion 62 abuts against the protruding portion 42 of the operating member 40 from below, and is capable of pushing up the operating member 40, the dispensing tube 50, and the piston 30. When a force of a certain level or more is applied in the vertical direction from the protruding portion 42, such as when a user presses down on the operating member 40 to dispense the contents, the abutment portion 62 is elastically deformed radially outward, and is capable of climbing over the protruding portion 42 in the vertical direction.

[0037] The metered dispensing container 1 according to the present embodiment described above provides the following advantageous effects.

[0038] To use this metered dispensing container 1, first, rotate the surrounding tube 22 from the state shown in Fig. 2 to release the threaded connection between the cylinder 20 and the cap member 10, and then lift up the cylinder 20. Then, because the lower end of the dispensing tube 50 is engaged with the container body 2 side (first tube portion 15A), the cylinder 20 rises ahead of the dispensing tube 50, piston 30, and operating member 40 until this engagement is released.

[0039] An elastic member 60 is provided between the cylinder 20 and the operating member 40, and when the cylinder 20 rises first, the operating member 40 side (contact portion 62) of the elastic member 60 elastically deforms downward relative to the cylinder 20 side (fixed portion 61), as shown by the two-dot chain line in Fig. 4. In other words, when the cylinder 20 is pulled upward, the contact portion 62 moves downward by Δh. Note that the engagement between the lower end of the dispensing tube 50 and the container body 2 side (first cylindrical portion 15A) is designed to be released when the elastic member 60 elastically deforms downward to a certain extent, before the elastic member 60 gets over the protruding portion 42.

[0040] When the engagement between the lower end of the dispensing cylinder 50 and the container body 2 side (first cylindrical portion 15A) is released by further pulling up the cylinder 20, the measuring member 3 can be removed from the container body 2 as shown in Fig. 3. At this time, the disengagement between the lower end of the dispensing cylinder 50 and the container body 2 side (first cylindrical portion 15A) causes the operating member 40 side (contact portion 62) of the elastic member 60 to restore and deform, pushing up the protruding portion 42 of the operating member 40. In other words, the contact portion 62 restores and deforms upward by an amount Δh from the state shown by the two-dot chain line in Fig. 4.

[0041] As a result, the protruding portion 42 is pushed up by the abutting portion 62, and the operating member 40, the dispensing cylinder 50, and the piston 30 rise relative to the cylinder 20. This increases the volume of the measuring chamber 100 inside the cylinder 20, and the contents corresponding to the increased volume are sucked upward from the dispensing outlet 51 of the dispensing cylinder 50, as shown in Figure 3, resulting in a so-called suck-back effect. Therefore, dripping from the dispensing outlet 51 of the dispensing cylinder 50 can be suppressed.

[0042] 5, with the measuring member 3 removed, pressing the push-down wall 41 and pushing down the operating member 40 causes the piston 30 to descend, pressurizing the measuring chamber 100 and causing the content in the measuring chamber 100 to be poured out through the communication hole 52 and the pouring outlet 51. Here, because the pouring outlet 51 of the pouring tube 50 is not fitted with a check valve to prevent dripping, the operating member 40 can be operated with less force than if a check valve were fitted.

[0043] Fig. 6 shows the state in which the contents are refilled after being poured out of the metering member 3. In Fig. 6, the left side of the page shows the state immediately after the metering member 3 is attached to the container body 2, and the right side of the page shows the state in which the contents are being filled after the metering member 3 is attached to the container body 2. In order to refill the contents into the metering member 3, first, as shown on the left side of the page in Fig. 6, the lower end of the pouring tube 50 protruding downward from the lower end opening of the cylinder 20 is engaged with the first tube portion 15A.

[0044] Next, as shown on the right side of Fig. 6, the flange 21 is pressed to push down the cylinder 20. This causes the cylinder 20 to move downward relative to the piston 30, increasing the volume of the measuring chamber 100, creating a negative pressure in the measuring chamber 100, and moving the check valve 4 away from the valve seat 17. This causes the content in the container body 2 to be sucked up by the pipe 5 and flow into the measuring chamber 100 through the pouring outlet 51 and the communication hole 52.

[0045] When the negative pressure in the measuring chamber 100 is released due to the inflow of the contents, the check valve 4 seats on the valve seat 17, and the inflow of the contents into the measuring chamber 100 stops. At this time, the measuring chamber 100 is in a state in which the desired amount of contents has been introduced.

[0046] The amount of content introduced into measuring chamber 100 in cylinder 20 depends on the amount of downward stroke of cylinder 20. In this way, after the content is measured in measuring chamber 100 by moving cylinder 20 downward, the content can be discharged by removing cylinder 20 from container body 2 and pressing down operating member 40, thereby providing excellent operability.

[0047] As explained above, the measuring and dispensing container 1 according to this embodiment comprises the container body 2 in which the contents are accommodated, and the measuring member 3 which is detachably attached to the container body 2 and which measures and dispenses the contents sucked up from the container body 2, and the measuring member 3 comprises the cylinder 20 in which the measuring chamber 100 for the contents is formed, the piston 30 which fits slidably within the cylinder 20, the operating member 40 which protrudes upward from the upper end opening of the cylinder 20 and moves up and down relative to the cylinder 20 together with the piston 30, the pouring outlet 51 which protrudes downward from the lower end opening of the cylinder 20, and a valve which connects the pouring outlet 51 and the measuring chamber 100. and a dispensing tube (50) that has a communication hole (52) through which the piston (30) and the operating member (40) can pass, and that moves up and down relative to the cylinder (20) together with the piston (30) and the operating member (40), and whose lower end, on which a dispensing outlet (51) is formed, is detachably engaged with the container body (2), and an elastic member (60) that is provided between the cylinder (20) and the operating member (40), and that elastically deforms the operating member (40) downward relative to the cylinder (20) due to the engagement between the dispensing tube (50) and the container body (2) when the cylinder (20) is pulled upward, and that restores the operating member (40) upward when the engagement between the dispensing tube (50) and the container body (2) is released, thereby increasing the volume of the measuring chamber (100). With this configuration, the measuring member (3) can be operated with a light force, and dripping from the measuring member (3) can be suppressed when it is removed from the container body (2).

[0048] In this embodiment, the outer peripheral surface of the operating member 40 has a protruding portion 42 that protrudes radially outward, and the elastic member 60 includes a fixed portion 61 fixed to the cylinder 20, a contact portion 62 that contacts the protruding portion 42 from below, and a groove portion 63 that is formed between the fixed portion 61 and the contact portion 62 and opens upward. According to this configuration, when the cylinder 20 rises ahead of the operating member 40, the contact portion 62 of the elastic member 60 that contacts the protruding portion 42 of the operating member 40 from below elastically deforms downward relative to the fixed portion 61 of the elastic member 60 fixed to the cylinder 20. The groove portion 63 that opens upward is provided between the fixed portion 61 and the contact portion 62, and by partially reducing the rigidity of the elastic member 60 between the fixed portion 61 and the contact portion 62, it is possible to facilitate downward elastic deformation of the contact portion 62 relative to the fixed portion 61.

[0049] In this embodiment, the container body 2 includes an attachment tube 15 to which the metering member 3 is detachably attached. The attachment tube 15 includes a first tubular portion 15A that engages with the lower end of the dispensing tube 50, a second tubular portion 15B that is connected to the upper end of the first tubular portion 15A and accommodates the peripheral wall of the cylinder 20, and a communication flow path 16 that penetrates the attachment tube 15 and connects the inside of the attachment tube 15 to the inside of the container body 2. With this configuration, when the metering member 3 is removed from the container body 2, outside air flows into the container body 2 through the communication flow path 16 of the attachment tube 15, thereby releasing the negative pressure inside the container body 2 caused by the suction of the contents of the container body 2. Furthermore, if the container body 2 falls over, the contents that have flowed into the attachment tube 15 can be returned to the container body 2 through the communication flow path 16 of the attachment tube 15.

[0050] 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.

[0051] For example, the measuring member 3 does not need to be screwed onto the cap member 10 or the mouth portion 2a of the container body 2 as long as the lower end of the dispensing cylinder 50 is detachably engaged with the first cylinder portion 15A. Furthermore, for example, a plurality of ribs extending in the vertical direction may be provided circumferentially on the outer peripheral surface of the peripheral wall of the cylinder 20 or on the inner peripheral surface of the second tubular portion 15B, allowing the peripheral wall of the cylinder 20 to slide within the second tubular portion 15B of the mounting tube 15, thereby preventing rattling when the measuring member 3 is attached or detached.

[0052] In addition, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and variations may be combined as appropriate, without departing from the spirit of the present invention.
