The present invention relates to a dispensing container.

BACKGROUND ART Conventionally, a discharge container as shown in Patent Document 1 below has been known. This discharge container includes a container body and a discharger (pump mechanism), and the contents of the container body are discharged from a discharge hole by operating the discharger.

Japanese Patent Application Laid-Open No. 2008-132406

Dispensing containers of this type are required to have a CR (child resistance) function. It should be noted that the CR function allows use by specific intended users (hereinafter simply referred to as “targeted users”), and prohibits use by non-targeted users such as infants and children (hereinafter simply referred to as “non-targeted users”). It means the function of suppressing.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a discharge container having a CR function.

In order to solve the above problems, a discharge container according to an aspect of the present invention includes a bottomed cylindrical container main body for containing a content, a mounting cap attached to the mouth of the container main body, and an upper attachment. a discharger having a stem disposed so as to be able to move downward in a state of force, and discharging the contents from the discharge hole as the stem moves downward with respect to the container body; Displaceable between a regulating position where the nozzle member attached to the stem abuts or approaches the abutment portion of the mounting cap from above, and a release position where the abutment portion is separated upward. a regulating member, wherein when the regulating member is positioned at the regulating position, vertical movement of the nozzle member with respect to the regulating member is regulated, and the regulating member is removed from the nozzle member and turned upside down; By being attached to the nozzle member again, the regulating member is configured to be displaceable between the regulating position and the releasing position, the regulating member has an operating portion projecting radially outward, and the regulating member When positioned at the release position, the vertical movement of the nozzle member with respect to the regulating member is restricted, and the discharge holes face upward .

According to the above aspect, when the regulating member is positioned at the regulating position, the regulating member abuts or approaches the abutting portion of the mounting cap from above, thereby regulating the downward movement of the regulating member. Furthermore, since the vertical movement of the nozzle member with respect to the restricting member is also restricted, the downward movement of the nozzle member and the stem with respect to the mounting cap is restricted, and the contents are not ejected from the ejection hole. On the other hand, when the regulating member is positioned at the release position, the regulating member is separated upward from the abutting portion of the mounting cap, so that downward movement of the regulating member is permitted. Therefore, the nozzle member and the stem can also move downward, and the contents can be discharged.
In this way, when the regulating member is in the regulating position, it is possible to suppress the ejection of the contents by the operation of the non-subject, while when the target person moves the regulating member to the release position, the contents can be ejected. As a result, the CR function can be realized.
Furthermore, in order to displace the regulating member from the regulating position to the release position, it is necessary to remove the regulating member from the nozzle member, turn it upside down, and attach it to the nozzle member again. In this way, by slightly complicating the operation of moving the restricting member to the release position, the CR function can be exhibited more reliably.

Further , since the regulating member has the operating portion, it is possible to improve operability when displacing the regulating member. Further, when the regulating member is positioned at the release position, the nozzle member and the stem can be moved downward through the regulating member by pressing the operating portion, thereby improving operability when discharging the contents. be able to.

Further, the regulating member may be configured to be removable from the nozzle member by moving upward with respect to the nozzle member.

In this case, for example, compared to the case where the restricting member is removed by moving it radially with respect to the nozzle member, it is possible to prevent the restricting member from coming off unexpectedly when an external force is applied to the restricting member. .

In addition, the discharge container of the above aspect further includes a cylindrical cap body having a topped cylindrical shape covering the nozzle member, the inner peripheral surface of the cap peripheral wall of the cap body decreasing in diameter as it goes upward, and the regulating member: The cap may not interfere with the cap peripheral wall of the cap body when positioned at the restricting position, and may interfere with the cap peripheral wall when positioned at the releasing position.

In this case, when the regulating member is positioned at the release position, the cap peripheral wall interferes with the regulating member, so the cap body cannot be attached to the discharge container. Therefore, it is possible to prevent the subject from forgetting to return the regulating member to the regulating position when storing the discharge container.

According to the above aspect of the present invention, it is possible to provide a discharge container with a CR function.

It is a semi-longitudinal sectional view of the discharge container of this embodiment. FIG. 2 is a developed view of the outer peripheral surface of the nozzle member of FIG. 1; 2 is a semi-longitudinal cross-sectional view showing a state in which the restricting member of FIG. 1 is displaced to a release position; FIG.

The discharge container of this embodiment will be described below with reference to the drawings.
As shown in FIG. 1, the discharge container 1 includes a bottomed cylindrical container body 2, a mounting cap 10, a discharger 20, a nozzle member 30 provided with a discharge hole 35a, a regulating member 40, and a cap. a body 50; The cap body 50 is formed in a truncated tubular shape and covers the mounting cap 10 , the nozzle member 30 and the regulating member 40 . Although the cap body 50 of this embodiment is attached to the container body 2, the cap body 50 may be attached to the mounting cap 10 or the like.

The container main body 2 accommodates liquid contents. A drug such as nasal drops can be used as the content. Note that drugs other than nasal drops or liquids other than drugs may be used as contents. Since the discharge container 1 of this embodiment has a CR function, which will be described later, contents such as drugs can be suitably used.

(direction definition)
The container body 2 and the dispenser 20 are arranged such that their central axes are on a common axis. In this embodiment, this common axis is referred to as container axis O, and the direction along container axis O is referred to as the vertical direction (container axial direction). In addition, along the vertical direction, the side of the cap body 50 is referred to as the upper side, and the opposite side (the bottom side of the container body 2) is referred to as the lower side. Further, in a plan view viewed from above and below, a direction intersecting the container axis O is called a radial direction, and a direction rotating around the container axis O is called a circumferential direction.
Among the radial directions, one direction is referred to as the front-rear direction, and the direction orthogonal to the front-rear direction is referred to as the left-right direction. Although illustration is omitted, the container main body 2 and the cap body 50 are formed in a substantially elliptical shape with a short axis in the front-rear direction and a long axis in the left-right direction in plan view.

(wearing cap)
The mounting cap 10 is mounted on the mouth portion 2 a of the container body 2 . The mounting cap 10 has a mounting tubular portion 11 , a contact portion 12 and an upper tubular portion 13 . A female threaded portion is formed on the inner peripheral surface of the mounting cylinder portion 11 to be screwed onto the male threaded portion of the mouth portion 2a. The mounting cap 10 is mounted on the mouth portion 2a by screwing the female thread portion of the mounting cylinder portion 11 onto the male thread portion of the mouth portion 2a. The cap 10 may be attached to the opening 2a by undercut fitting or the like, instead of screwing.

A ratchet mechanism R is provided between the mounting tube portion 11 and the mouth portion 2a. The ratchet mechanism R is arranged below the female threaded portion of the mounting tube portion 11 and the male threaded portion of the mouth portion 2a. The ratchet mechanism R permits rotation of the opening 2a of the mounting cylinder 11 about the container axis O in the tightening direction and restricts rotation in the loosening direction. The ratchet mechanism R prevents, for example, a non-target person from removing the mounting cap 10 from the container body 2 and opening the mouth portion 2a.

The contact portion 12 extends radially inward from the upper end portion of the mounting tube portion 11 and has an annular shape in a plan view. The contact portion 12 faces the upper edge of the mouth portion 2a via a flange portion and packing of a cylinder 22, which will be described later. That is, the flange portion and packing of the cylinder 22 are sandwiched between the contact portion 12 and the mouth portion 2a.

The upper tubular portion 13 extends upward from the inner peripheral edge of the contact portion 12 . A vertical rib 13 a is formed on the outer peripheral surface of the upper cylindrical portion 13 so as to protrude radially outward and extend in the vertical direction.

(dispenser)
The discharger 20 has a stem 21 , a cylinder 22 , a biasing member 23 , a valve body 24 and a pipe 25 . The stem 21 is arranged so as to be able to move downward while being biased upward. The stem 21 as a whole is formed in a tubular shape extending in the vertical direction. The stem 21 is configured by combining a first member 21a, a second member 21b, and a third member 21c. Alternatively, the stem 21 may be formed of a single member. The stem 21 is vertically movable with respect to the cylinder 22 . The cylinder 22 is formed in a tubular shape surrounding the lower portion of the stem 21 . An annular flange portion extending radially outward is formed at the upper end portion of the cylinder 22 .

The biasing member 23 is provided inside the cylinder 22 . A biasing member 23 applies an upward biasing force to the stem 21 . Therefore, when the downward force is released after the stem 21 is pushed down and lowered, the stem 21 is restored and displaced by the urging force of the urging member 23 .

The valve body 24 is provided inside the cylinder 22 . The valve body 24 is spherically formed. The valve body 24 is in contact with a valve seat formed in the cylinder 22 from above, thereby closing the lower end of the cylinder 22 . When the valve body 24 moves upward from the valve seat portion of the cylinder 22, the lower end portion of the cylinder 22 is opened, and the inside of the container body 2 and the inside of the cylinder 22 are communicated. A pipe 25 is attached to the lower end of the cylinder 22 . Although not shown, the lower end of the pipe 25 extends to near the bottom of the container body 2 .

When the stem 21 moves downward with respect to the cylinder 22 (container body 2 and mounting cap 10 ), the internal pressure of the cylinder 22 increases and the contents in the cylinder 22 flow upward through the stem 21 . As a result, the content is discharged from the discharge hole 35a of the nozzle member 30. As shown in FIG. When the stem 21 rises (restoring displacement) with respect to the cylinder 22, the inside of the cylinder 22 becomes negative pressure. As a result, the valve body 24 moves upward from the valve seat, and the contents of the container body 2 are sucked up through the pipe 25 and supplied to the cylinder 22 . In this manner, the dispenser 20 is configured to discharge the contents of the container body 2 from the discharge hole 35a as the stem 21 moves up and down with respect to the cylinder 22 .

(Nozzle member)
The nozzle member 30 has a discharge cylinder portion 31 , a tapered cylinder portion 32 and a lower cylinder portion 33 . The discharge tube portion 31 is formed in a tubular shape extending in the vertical direction. The upper end portion of the stem 21 (the upper end portion of the third member 21 c ) is fitted into the discharge cylinder portion 31 . Thereby, the nozzle member 30 is attached to the upper end portion of the stem 21 . Therefore, the nozzle member 30 moves up and down together with the stem 21 . The tapered tubular portion 32 connects the discharge tubular portion 31 and the lower tubular portion 33 . The tapered tubular portion 32 extends radially outward from the central portion of the discharge tubular portion 31 in the vertical direction, and gradually expands in diameter downward.

A nozzle tip 35 is provided at the upper end portion of the discharge cylinder portion 31 . The nozzle tip 35 is formed in a truncated cylindrical shape coaxial with the axis O of the container. The nozzle tip 35 is fitted and fixed inside the upper end portion of the discharge tube portion 31 . A through hole is formed in the top of the nozzle tip 35 so as to penetrate the top in the vertical direction. In this embodiment, this through-hole is the discharge hole 35a. Alternatively, the nozzle tip 35 may not be provided, and for example, the upper end opening of the discharge tube portion 31 may be used as the discharge hole.

The lower tubular portion 33 is formed in a vertically extending cylindrical shape and extends downward from the lower end portion of the tapered tubular portion 32 . The outer diameter of the lower tubular portion 33 is larger than the outer diameter of the discharge tubular portion 31 . The lower tubular portion 33 surrounds the lower portion of the discharge tubular portion 31 from the radial outside. The lower tubular portion 33 surrounds the upper end portion of the upper tubular portion 13 of the mounting cap 10 from the outside in the radial direction. The inner peripheral surface of the lower tubular portion 33 is formed with a vertical groove 33a that is recessed radially inward and extends in the vertical direction.

The vertical rib 13a of the mounting cap 10 is positioned in the vertical groove 33a, thereby restricting the rotational movement of the nozzle member 30 about the container axis O with respect to the mounting cap 10. As shown in FIG. Further, when the nozzle member 30 moves up and down with respect to the mounting cap 10, the movement of the nozzle member 30 is guided by the vertical ribs 13a sliding within the vertical grooves 33a. Note that the relationship between the vertical grooves 33a and the vertical ribs 13a may be reversed. That is, the nozzle member 30 may be formed with vertical ribs and the mounting cap 10 may be formed with vertical grooves.

(Guide groove and regulation member)
Here, in this embodiment, a guide groove 34 is formed in the nozzle member 30 . The guide groove 34 is recessed radially inward from the outer peripheral surfaces of the lower tubular portion 33 and the tapered tubular portion 32 . A protrusion 43 of the regulating member 40 is arranged in the guide groove 34 , and the protrusion 43 can move along the guide groove 34 . In this embodiment, two guide grooves 34 and two protrusions 43 are formed. The number of guide grooves 34 and protrusions 43 can be changed as appropriate.
The guide groove 34 and the regulating member 40 will be described in more detail below.

The regulating member 40 has a body portion 41 , an operating portion 42 and projections 43 . The body portion 41 is formed in a cylindrical shape extending in the vertical direction, and surrounds the lower cylindrical portion 33 of the nozzle member 30 from the outside in the radial direction. A projection 43 that protrudes radially inward is formed on the inner peripheral surface of the body portion 41 . The protrusion 43 is formed in a cylindrical shape extending in the radial direction.

The operating portion 42 protrudes radially outward from the lower end portion of the main body portion 41 . Although illustration is omitted, the operation portion 42 is formed in a substantially elliptical shape in a plan view. This makes it easy to apply force in the circumferential direction to the restricting member 40 when the operating portion 42 is gripped. Note that the operation portion 42 is not limited to a substantially elliptical shape, and may be formed in a non-circular shape such as a polygonal shape. A protrusion 42 a that protrudes downward is provided on the outer peripheral edge of the operating portion 42 . In this embodiment, the protrusion 42 a is provided on a part of the outer peripheral edge of the operation portion 42 . More specifically, protrusions 42 a are provided at both ends in the major axis direction of the substantially elliptical operating portion 42 . The protrusion 42a can be used as a finger hook when operating the restricting member 40. As shown in FIG.

FIG. 2 is a developed view of the outer peripheral surface of the nozzle member 30. As shown in FIG. A straight line L shown in FIG. 2 indicates the boundary between the tapered tubular portion 32 and the lower tubular portion 33 . As shown in FIG. 2, the guide groove 34 has a longitudinal groove portion 34a and a lateral groove portion 34b. The vertical groove portion 34a extends along the vertical direction across the boundary (straight line L) between the tapered tubular portion 32 and the lower tubular portion 33 . That is, the upper end portion of the vertical groove portion 34 a is located in the tapered tubular portion 32 , and the lower end portion of the vertical groove portion 34 a is located in the lower tubular portion 33 .

The outer diameter of the tapered tubular portion 32 gradually decreases upward. Therefore, the vertical groove portion 34a is open upward (see FIG. 1). Therefore, when the projection 43 is moved upward along the vertical groove portion 34a, the projection 43 can be removed upward from the vertical groove portion 34a.

The lateral groove portion 34b extends in the circumferential direction from the lower end portion of the vertical groove portion 34a. A protrusion 34c that protrudes upward is formed between the lower inner surface of the lateral groove portion 34b and the lower inner surface of the vertical groove portion 34a. The projecting portion 34c is formed in a curved surface that is convex upward.

In this embodiment, the position of the regulating member 40 when the projection 43 is positioned within the lateral groove portion 34b and the operation portion 42 is positioned below the projection 43 is referred to as the regulating position. Further, the position of the restricting member 40 when the projection 43 is positioned within the lateral groove portion 34b and the operation portion 42 is positioned above the projection 43 is called the release position. The restricting member 40 can be displaced between the restricting position and the releasing position. 1 shows the case where the regulating member 40 is positioned at the regulating position, and FIG. 3 shows the case where the regulating member 40 is positioned at the release position. As shown in FIGS. 1 and 3, the regulating member 40 is upside down between the release position and the regulating position.

As shown in FIG. 1, when the regulating member 40 is positioned at the regulating position, the regulating member 40 abuts or approaches the mounting cap 10 from above. More specifically, the bottom surface of the main body portion 41 (the bottom surface of the operation portion 42 ) is in contact with or close to the top surface of the contact portion 12 . Therefore, even if a downward force is applied to the regulating member 40, the regulating member 40 abuts against the contact portion 12, so the downward movement of the regulating member 40 is regulated.

In addition, since the protrusion 43 is positioned within the lateral groove portion 34b, when the restricting member 40 is moved vertically with respect to the nozzle member 30, the protrusion 43 hits the upper inner surface or the lower inner surface of the lateral groove portion 34b. touch. Therefore, relative vertical movement of the regulation member 40 and the nozzle member 30 is also regulated. That is, when the restricting member 40 is positioned at the restricting position, the downward movement of the restricting member 40, the nozzle member 30, and the stem 21 to which the nozzle member 30 is mounted is restricted.

On the other hand, as shown in FIG. 3, when the regulating member 40 is positioned at the release position, the regulating member 40 is separated upward from the contact portion 12 of the mounting cap 10, and the contact portion 12 and the regulating member 40 are separated from each other. A vertical gap is formed between them. Therefore, when a downward force is applied to the regulating member 40, the regulating member 40 moves downward. In other words, downward movement of the regulating member 40, the nozzle member 30, and the stem 21 is permitted when the regulating member 40 is positioned at the release position.

Further, since the projection 43 is positioned within the lateral groove portion 34b, the projection 43 contacts the lower inner surface of the lateral groove portion 34b when the restricting member 40 moves downward. Thereby, the downward force applied to the regulating member 40 is also transmitted to the nozzle member 30 . Furthermore, the nozzle member 30 is attached to the stem 21 . Therefore, when the regulation member 40 moves downward, the nozzle member 30 and the stem 21 also move downward together. That is, by pressing down the regulating member 40, the content can be discharged from the discharge hole 35a.

To move the regulating member 40 from the regulating position to the release position, first, the cap body 50 is removed from the container body 2 . Next, the regulating member 40 is rotated around the container axis O with respect to the nozzle member 30 . As a result, the protrusion 43 moves in the lateral groove portion 34b in the circumferential direction, climbs over the protrusion 34c, and reaches the vertical groove portion 34a. Next, the regulation member 40 is moved upward. As a result, the projection 43 moves upward within the longitudinal groove portion 34a. Then, the protrusion 43 is removed upward from the opening at the upper end of the vertical groove portion 34a, and the restricting member 40 is removed from the nozzle member 30. As shown in FIG.

Next, the regulation member 40 is turned upside down and attached to the nozzle member 30 again. At this time, the projection 43 is introduced into the guide groove 34 from the opening at the upper end of the vertical groove portion 34a. Then, the regulating member 40 is lowered with respect to the nozzle member 30, and when the projection 43 reaches the connecting portion between the longitudinal groove portion 34a and the lateral groove portion 34b, the regulating member 40 is rotationally moved in the circumferential direction. As a result, the protrusion 43 is introduced into the lateral groove portion 34b over the protrusion 34c, and the restricting member 40 is positioned at the release position.

As described above, according to the discharge container 1 of the present embodiment, when the regulating member 40 is positioned at the regulating position, the downward movement of the nozzle member 30 and the stem 21 with respect to the mounting cap 10 is regulated, and the contents are released. It will be in a state where it is not discharged from the discharge hole 35a. On the other hand, when the regulating member 40 is positioned at the release position, the nozzle member 30 and the stem 21 are allowed to move downward, and the contents can be discharged.

In this way, when the regulating member 40 is at the regulating position, it is possible to suppress the discharge of the contents by the operation of the non-target person, while when the target person moves the regulating member 40 to the release position, the contents are released. Discharging becomes possible, and the CR function can be realized.
Furthermore, in order to displace the regulating member 40 from the regulating position to the release position, it is necessary to remove the regulating member 40 from the nozzle member 30, turn it upside down, and attach it to the nozzle member 30 again. By slightly complicating the operation of moving the regulating member 40 to the release position in this manner, the CR function can be exhibited more reliably.

In addition, the restricting member 40 has an operating portion 42 protruding radially outward. Thereby, the operability when displacing the restricting member 40 can be improved. Further, when the regulating member 40 is positioned at the release position, by pressing the operating portion 42, the nozzle member 30 and the stem 21 can be moved downward via the regulating member 40, thereby discharging the contents. Operability can be improved. Furthermore, the nozzle member 30 is not formed with such an operating portion. Therefore, for example, it is possible to prevent the nozzle member 30 from being pushed down while the restricting member 40 is positioned in the vertical groove portion 34a.

Further, the regulation member 40 is configured to be removable from the nozzle member 30 by moving upward with respect to the nozzle member 30 . As a result, when an external force is applied to the regulating member 40, the regulating member 40 is unexpectedly disengaged, for example, compared to the case where the regulating member 40 is removed by moving it radially with respect to the nozzle member 30. can be suppressed.

A guide groove 34 is formed in the nozzle member 30 , and a projection 43 arranged inside the guide groove 34 is provided in the regulation member 40 . By moving the protrusion 43 along the guide groove 34 , the restricting member 40 can be removed from the nozzle member 30 . With this configuration, it is possible to easily adjust the complexity of the operation when removing the restricting member 40 from the nozzle member 30 . Therefore, the operation for moving the restricting member 40 to the release position is made difficult for the non-target person and easy for the target person, so that the CR function can be realized more reliably.

In addition, the inner peripheral surface of the cap peripheral wall 51 of the cap body 50 is tapered upward. In this embodiment, the cap peripheral wall 51 has a small diameter portion 51a and a large diameter portion 51b. The small diameter portion 51a is located above the large diameter portion 51b and has an inner diameter smaller than that of the large diameter portion 51b. In this manner, the inner diameter of the cap peripheral wall 51 gradually decreases upward.

The outer diameter of the operating portion 42 of the regulating member 40 is smaller than the inner diameter of the large diameter portion 51b and larger than the inner diameter of the small diameter portion 51a. When the regulating member 40 is positioned at the release position, the regulating member 40 interferes with the small diameter portion 51a of the cap peripheral wall 51 (see FIG. 3). Therefore, it is impossible to attach the cap body 50 to the discharge container 1 while the regulating member 40 is in the release position. Therefore, when storing the discharge container 1, it is possible to prevent the target person from forgetting to return the regulating member 40 to the regulating position.

Further, inside the guide groove 34, a protrusion 34c that protrudes upward is provided. Therefore, when the projection 43 is introduced from the vertical groove portion 34a into the lateral groove portion 34b, the projection 43 rides over the projection portion 34c, resulting in a click feeling. This configuration makes it easier for the user to recognize that the restricting member 40 has reached the restricting position or the releasing position, thereby further improving operability.

Furthermore, the protrusion 34c prevents the protrusion 43 from moving into the vertical groove 34a when the protrusion 43 is positioned in the lateral groove 34b. As a result, the restricting member 40 is stably positioned at the restricting position or the releasing position, and the operability can be further improved.

The technical scope of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, in the above embodiment, the inner diameter of the cap peripheral wall 51 changes stepwise. However, the inner peripheral surface of the cap peripheral wall 51 may gradually decrease in diameter as it goes upward. In this case, the cap peripheral wall 51 may be formed in a tapered tubular shape.

In addition, it is possible to appropriately replace the components in the above-described embodiment with known components without departing from the scope of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
