Japanese Patent Application Publication No. 2015-145257

By the way, a pourer is used, for example, when multiple types of contents are stored in the container body, after mixing the multiple types of contents in the container body by shaking the container body, etc. May be poured out. In this case, depending on the user of the dispenser and the manner in which it is used, there is a possibility that the cap may be opened without shaking the container body. In this case, there is a possibility that the contents are poured out from the spout in a non-uniform state in which the contents are not mixed with each other. As a result, it may be difficult to use up the contents effectively, or the desired effects of the contents may not be obtained.
Also, if you open the cap without shaking it and realize that you forgot to shake it before dispensing the contents, you will need to attach the cap, shake the dispenser, and open the cap again. . Therefore, the conventional dispenser causes the user to feel troublesome.

The present invention provides a dispenser that facilitates mixing of contents before opening the cap and can dispense a homogeneous mixture.

In order to solve the above problems, the present invention employs the following aspects.
A spout according to one aspect of the present invention includes a stopper having a spout for pouring out contents in a container body, and a stopper disposed coaxially with an axis along an up-down direction, and a spout around the axis. a cap that is removably attached to the mouth of the container body by relative rotation with the main body and closes the spout; a regulation position that regulates the relative rotation of the stopper and the cap about the axis; and a regulation position that regulates the relative rotation of the stopper and the cap about the axis. a locking portion that is provided so as to be movable in the vertical direction with respect to the plug body and the cap between allowable positions that are located above the position and permit relative rotation of the plug body and the cap about the axis; and is linked to the lock part, and is engaged with a first engaging part formed on the cap when the lock part is in the permissible position, and controls the lock part with respect to the plug body and the cap. a lift section that restricts downward movement to a position; and a lift section that is provided so as to be movable in the vertical direction by its own weight with respect to the lock section and the lift section; a weight portion for pushing upward, the lift portion being pushed up as the weight portion moves upward with respect to the lock portion and the lift portion, and configured to be able to climb over the first engaging portion. There is.

According to this aspect, by moving the container body in the vertical direction by shaking the container body or the like, the weight portion is moved upward with respect to the lock portion and the lift portion. Then, the weight portion collides with the lift portion from below, thereby pushing up the lock portion and the lift portion. As a result, the lift portion moves upwardly over the first engaging portion, and the lock portion moves from the restriction position to the allowable position. That is, in the dispenser of this embodiment, the cap cannot be opened unless the container body is shaken to the extent that the weight portion moves relative to the container body. Therefore, the user can be prompted to stir the contents, and it is possible to prevent the contents from being poured out due to forgetting to shake the container body. As a result, the contents can be poured out in a homogeneous state. Furthermore, with the dispenser of this embodiment, it is possible to prevent forgetting to shake the container body, thereby improving convenience. In addition, in the dispenser of this aspect, when opening the container, it is necessary to shake the container body with such force that the weight moves relative to the container body, etc., so it is possible to prevent the cap from being opened by mischief etc. (Childproof function).
Furthermore, in this aspect, since the lock portion moves from the restriction position to the permissible position as the contents are stirred, no separate operation is required to move the lock portion to the permissible position. Therefore, it is possible to prevent the operability from being impaired when opening the dispenser.

In the dispenser of the above aspect, the locking portion comes into contact with at least one of the stopper and the cap from below in the process of moving the locking portion from the restriction position to the permissible position. An opening suppressing part is formed that restricts upward movement of the locking part with respect to the cap and allows the locking part to climb over the first engaging part as the lift part goes over the first engaging part. It is preferable.
According to this aspect, when the lock portion attempts to move toward the permissible position due to, for example, a fall of the container body, the movement of the lock portion toward the permissible position is regulated by the cap-opening suppressing portion. Thereby, it is possible to prevent the lock portion from unexpectedly moving to the permissible position, and it is possible to prevent the contents from being poured out in a non-uniform state.

In the dispenser of the above aspect, a portion of the cap located below the first engaging portion is provided with the lift portion in the process of moving the lock portion from the restriction position to the permissible position. It is preferable that the second engaging portion is formed such that the second engaging portion can be climbed over.
According to this aspect, in the process of moving the lock part from the restriction position to the permissible position, it is necessary to overcome at least two engaging parts. That is, since the lock part will not move to the permissible position unless the container body is shaken multiple times, it is possible to suppress variations in the mixing status of the contents when the lock part moves to the permissible position.

In the dispenser of the above aspect, it is preferable that the first engaging part and the second engaging part are arranged at positions separated from each other in a circumferential direction around the axis.
According to this aspect, when the lift part moves upward, it is possible to prevent the lift part from climbing over the first engaging part and the second engaging part all at once. Therefore, it is possible to prevent the lock portion from moving to the permissible position in a state where the contents are not homogeneous.

In the dispenser of the above aspect, the lift part is a first elastic piece that overlaps at least a part of the first engaging part in a plan view and gets over the first engaging part as it is elastically deformed in the vertical direction. is arranged at the same height as the first elastic piece in the vertical direction, and at least partially overlaps the second engaging part in plan view, and the second engaging part is elastically deformed in the vertical direction. It is preferable to include a second elastic piece that goes over the portion.
According to this aspect, it is possible to suppress deformation of all the elastic pieces when, for example, the lower engagement part (for example, the second engagement part) is overcome among the engagement parts adjacent in the vertical direction. This prevents the elastic piece from reaching the upper engaging part (for example, the first engaging part) without fully restoring after passing through the lower engaging part, and prevents the elastic piece from reaching the upper engaging part (for example, the first engaging part). You can prevent them from overcoming all at once. Therefore, it is possible to prevent the lock portion from moving to the permissible position in a state where the contents are not homogeneous.

In the spout according to the aspect described above, when the lock part is in the permissible position and the lift part is located above the first engaging part, the lock part is opened from below. At the same time, an engaging protrusion is formed which the locking part can ride over as the locking part moves upward, and the engaging force acting between the locking part and the engaging protrusion is applied to the lift part. It is preferable that the engagement force is greater than the engagement force that acts between the first engagement portion and the first engagement portion.
According to this aspect, when the cap is opened, the lock part engages with the engagement protrusion from below, so that the cap tends to rise with respect to the lock part and the lift part. At this time, since the engagement force acting between the lock part and the engagement protrusion is larger than the engagement force acting between the lift part and the first engagement part, as the cap moves upward, , the lift part is pulled down via the lock part. As a result, before the locking portion climbs over the engaging protrusion upward, the elastic piece rides over each engaging portion downward, and the locking portion and the lift portion descend with respect to the cap. Therefore, the lift part can be reset to the initial state (below the first engaging part) with the opening operation. Thereby, it is not necessary to return the lift portion to the initial state by an operation separate from the opening operation, so that excellent operability can be provided.

According to the present invention, it is possible to promote mixing of the contents before opening the bottle and to pour out a homogeneous mixture.

The second engaging portion 66 protrudes outward in the radial direction from a portion of the second positioning piece 61b located between the first engaging portion 65 and the third engaging portion 67 in the vertical direction. That is, the second engaging part 66 is arranged at a position that does not overlap the first engaging part 65 and the third engaging part 67 in a plan view (separate position in the circumferential direction). Note that the protrusion amounts of each of the engaging portions 65 to 67 may be equal to each other or may be different from each other.

As shown in FIGS. 1 and 2, the inner cap 56 is fixed to the inner side of the outer cap 55 so as not to be relatively movable. The inner cap 56 includes a guide tube 71, a weight accommodating portion 72, and a closing portion 73.
The guide tube 71 is fitted within the peripheral wall portion 55a of the outer cap 55. A guide groove 71a is formed in the inner peripheral surface of the guide cylinder 71. The guide groove 71a is opened radially inward and extends in the vertical direction. For example, a pair of guide grooves 71a are formed on the inner peripheral surface of the guide tube 71 at positions facing each other in the radial direction.

The weight accommodating portion 72 is arranged inside the guide cylinder 71. The weight accommodating portion 72 is formed into a cylindrical shape with a bottom. Specifically, the weight accommodating portion 72 includes an outer cylinder 76, an inner cylinder 77, and a bottom wall portion 78.

The stopper tube 82 extends downward from the facing portion 81 . The stopper cylinder 82 fits tightly into the tapered cylinder 37 in the closed position of the cap body 50. Note that the closed position of the cap body 50 is a state in which the outer cap 55 is screwed onto the cap mounting portion 3a and the spout 8 is closed.

The switching mechanism 51 moves the cap unit 21 from a state in which it cannot be opened to a state in which it can be opened by shaking the pouring container 10 in the vertical direction. The switching mechanism 51 includes a lock section 100, a weight section 101, and a lift section 102.

The lock portion 100 is configured to be movable in the vertical direction relative to the stopper 20 and the cap body 50. Specifically, the lock portion 100 includes a base portion 110, a plug engaging portion 111, a plug opening stopper 112, and a connecting portion 113.
The base portion 110 is formed in an annular shape coaxially with the container axis O. The base portion 110 is disposed inside the guide tube 71 so as to surround the spout tube 34 when the cap body 50 is in the closed position. Note that the inner circumferential edge of the base portion 110 is located on the outer side in the radial direction than the opening prevention portion 45 and the engagement protrusion 46 described above.

A guide protrusion 110a is formed in a portion of the outer peripheral edge of the base portion 110 that faces the guide groove 71a in the radial direction. The guide projection 110a projects radially outward from the base portion 110. The guide protrusion 110a engages with the inner surface of the guide groove 71a in the circumferential direction. Thereby, the guide protrusion 110a is allowed to move in the vertical direction within the guide groove 71a, with movement in the circumferential direction being restricted. Therefore, rotation of the switching mechanism 51 around the container axis O with respect to the cap body 50 is restricted.

The plug engaging portion 111 extends downward from the base portion 110. The plug engaging portion 111 is formed into a plate shape with the circumferential direction being the thickness direction and extending in the radial direction. In the illustrated example, a pair of plug engaging portions 111 are formed at positions facing each other in the radial direction with the container axis O in between.

The lock part 100 moves up and down with respect to the cap body 50 when the cap body 50 is in the closed position, so that the cap engaging part 111 moves forward and backward with respect to the accommodation groove 43 . Specifically, the locking part 100 has two positions: a restricted position where the plug engaging part 111 is housed in the housing groove 43, and a permissible position where the plug engaging part 111 is separated upward from the housing groove 43 (see FIG. 6). and move between. The plug engaging portion 111 engages with the inner surface of the housing groove 43 (the opposing surfaces of the closing direction regulating portion 41 and the opening direction regulating portion 42) in the circumferential direction at the regulating position of the locking portion 100. When the locking portion 100 is in the restriction position, the cap unit 21 is restricted from moving in the circumferential direction relative to the plug 20 (container body 2) via the plug engaging portion 111.
On the other hand, the plug engaging portion 111 is disengaged from the rotation regulating portion 40 when the locking portion 100 is in the allowable position. Thereby, the cap unit 21 is allowed to move in the circumferential direction with respect to the stopper 20 (container body 2) at the allowable position of the lock portion 100.

The plug-opening stopper 112 projects radially inward from the plug engaging portion 111 . The opening stopper 112 is located below the opening suppressing part 45 when the lock part 100 is in the restriction position. On the other hand, the cap-opening stopper 112 is arranged above the cap-opening suppressing portion 45 when the locking portion 100 is in the allowable position. Specifically, the opening stopper 112 includes a large protrusion 112a and a small protrusion 112b continuous below the large protrusion 112a.

The large protrusion 112a overlaps the opening suppressing portion 45 and the engagement protrusion 46 in a plan view when the cap main body 50 is in the closed position. The large protrusion 112a interferes with (contacts) the opening suppressing part 45 and the engagement protrusion 46 in the process of the locking part 100 transitioning between the restriction position and the permissible position, and also interferes with the opening suppressing part 45 and the engaging projection 46. It is configured to be able to climb over both of the protrusions 46. The large protrusion 112a is configured to be able to engage with the opening suppressing portion 45 from below when the locking portion 100 is in the restriction position.

The small protrusion 112b projects smaller in the radial direction from the plug engaging portion 111 than the large protrusion 112a. The small protrusion 112b overlaps the engagement protrusion 46 in a plan view when the cap body 50 is in the closed position. The small protrusion 112b interferes with (contacts) only the engagement protrusion 46 while the lock part 100 moves between the restriction position and the allowable position, and also interferes with both the opening suppressing part 45 and the engagement protrusion 46. It is constructed so that it can be overcome. The small protrusion 112b is configured to be able to engage with the engagement protrusion 46 from above when the lock portion 100 is in the allowable position (see FIG. 8).

The connecting portions 113 extend upward from portions of the base portion 110 that overlap with the plug engaging portions 111 in plan view. Each connecting portion 113 is formed, for example, in a cylindrical shape extending in the vertical direction. A locking protrusion 113a projecting outward from the connecting portion 113 is formed on the upper edge of each connecting portion 113. In addition, each connection part 113 may form a slit extending in the up-down direction, for example, and may be configured to be elastically deformable in a direction intersecting the up-down direction. Moreover, the connecting part 113 may be arranged at a position shifted from the plug engaging part 111.

The weight part 101 is configured to be movable in the vertical direction by its own weight with respect to the lock part 100 and the lift part 102 by inertia that acts when the pouring container 10 is shaken. When the weight portion 101 is at the lowest end position, the entire weight portion 101 is accommodated in the weight accommodating portion 72. When the weight portion 101 is at the uppermost position, at least the upper end portion of the weight portion 101 slips out of the weight accommodating portion 72 and protrudes above the inner cylinder 77 (see FIG. 4).

The weight portion 101 includes a main body portion 101a and a protrusion portion 101b.
The main body portion 101a is formed in an annular shape disposed coaxially with the container axis O in plan view.
The protruding portion 101b protrudes downward with respect to the main body portion 101a. The protrusion 101b is housed in the through hole 78a when the weight 101 is at the lowest position.

The connecting portion 113 passes through the weight portion 101 at a position overlapping the connecting portion 113 in a plan view. Thereby, the weight part 101 is allowed to move in the vertical direction while being restricted from moving in the circumferential direction relative to the lock part 100.

It is preferable that the weight portion 101 is formed of a material having a higher specific gravity than the lock portion 100 and the lift portion 102, for example. In this case, the weight portion 101 may be formed of a metal material or the like. However, the weight portion 101 may be formed of the same material (resin material) as the lock portion 100 and the lift portion 102. Further, the shape, weight, etc. of the weight portion 101 can be changed as appropriate. In this case, the weight portion 101 may have a structure in which the weight body is movably housed inside a box, for example.

The lift section 102 includes a support ring 120 and an elastic piece 121.
The support ring 120 is formed in an annular shape coaxially with the container axis O. An insertion hole 120a is formed in a portion of the support ring 120 that overlaps the connecting portion 113 in plan view. The connecting portions 113 are individually inserted into the insertion holes 120a. Thereby, the lift part 102 is allowed to move in the vertical direction while being restricted from moving in the circumferential direction relative to the lock part 100.

The support ring 120 overlaps the weight portion 101 from above. The weight portion 101 contacts the support ring 120 from below as the weight portion 101 moves upward with respect to the lift portion 102 . That is, the impact force of the weight portion 101 acts upwardly on the lift portion 102 via the support ring 120. The support ring 120 pulls the lock part 100 upward via the locking protrusion 113a when the impact force of the weight part 101 or the like acts upward.

As shown in FIGS. 1 to 3, the elastic piece 121 protrudes radially inward from the inner peripheral edge of the support ring 120. As shown in FIGS. The circumferential width of the elastic piece 121 gradually decreases toward the inside in the radial direction. The elastic piece 121 is thinner than the support ring 120. The elastic piece 121 is configured to be elastically deformable in the vertical direction. A plurality of (for example, four) elastic pieces 121 in this embodiment are formed at intervals in the circumferential direction. In the example shown in FIG. 3, each of the elastic pieces 121 faces one positioning piece 61 in the radial direction.

The radially inner end of each elastic piece 121 overlaps any of the engaging portions 65 to 67 in plan view when the cap body 50 is in the closed position. That is, among the elastic pieces 121, the elastic pieces (first elastic pieces) 121 disposed at opposing positions in the first direction with the container axis O in between are the first elastic pieces 121 that engage the first engagement portion 65 and the third engagement portion. It overlaps the joining part 67 in plan view. On the other hand, among the elastic pieces 121, the elastic pieces (second elastic pieces) 121 disposed at positions facing each other in the above-mentioned second direction with the container axis O in between are attached to the second engaging portion 66 in a plan view. overlap. The elastic piece 121 is configured to interfere with the engaging parts 65 to 67 and to be able to ride over the engaging parts 65 to 67 in the process of moving up and down with respect to the cap body 50.

When the lock portion 100 is in the restriction position, at least one of the elastic pieces 121 is located below the first engaging portion 65. On the other hand, when the lock part 100 is in the allowable position, all the elastic pieces 121 are located above the first engaging part 65. In this case, any of the elastic pieces 121 is engaged with the first engaging part 65 from above, thereby suppressing the lowering of the lift part 102 with respect to the cap body 50. In this embodiment, the distance in the vertical direction between the elastic piece 121 and the large protrusion 112a is set to be equal to or less than the distance in the vertical direction between the first engaging part 65 and the stopper opening suppressing part 45. As a result, when the elastic piece 121 moves upward over the first engaging part 65, the large protrusion 112a moves upward over the opening suppressing part 45. Note that each elastic piece 121 may be arranged to straddle between adjacent positioning pieces 61 (first positioning piece 61a and second positioning piece 61b). Moreover, each elastic piece 121 may be formed in a ring shape so as to be continuous with each other, or may be provided only in a part of the circumferential direction.

Next, as a method of using the above-mentioned pouring container 10, a method for pouring out the contents will be explained. In the following description, a state in which the cap body 50 is in the closing position, the lock part 100 is in the regulating position, and the elastic piece 121 is located below the third engaging part 67 will be described as an initial state. do. That is, in the initial state, the cap unit 21 is circumferentially engaged with the rotation regulating portion 40 of the cap body 20 via the cap engagement portion 111, so that movement of the cap body 50 to the open position is prevented. regulated.
To pour out the contents, first shake the pouring container 10 in its initial state up and down several times. Then, by repeatedly moving the pouring container 10 in the vertical direction, the contents contained in the container body 2 are stirred, and different types of contents are mixed in the container body 2.

Here, the switching mechanism 51 is configured to be movable relative to the container body 2, the stopper body 20, and the cap body 50 in the vertical direction. Moreover, in the switching mechanism 51, the weight portion 101 is configured to be movable relative to the lock portion 100 and the lift portion 102 in the vertical direction. Therefore, as shown in FIG. 4, due to inertia acting on the switching mechanism 51 due to the vertical movement of the entire pouring container 10, the weight portion 101 first moves relative to the lock portion 100 and the lift portion 102 in the vertical direction. When the weight part 101 moves upward with respect to the lock part 100 and the lift part 102, the weight part 101 collides with the lift part 102 from below the lift part 102. Then, the lift portion 102 is pushed upward. As a result, the positioning piece 61a or the elastic piece 121 is elastically deformed, so that the elastic piece 121 overcomes the third engaging portion 67 upward. Then, as the lift section 102 moves upward, the lock section 100 is pulled up by the lift section 102 via the locking protrusion 113a.

As shown in FIGS. 5 and 6, by repeatedly shaking the pouring container 10 in the vertical direction, the weight portion 101 repeatedly collides with the lift portion 102 from below the lift portion 102. As a result, the elastic piece 121 sequentially overcomes the second engaging portion 66 and the first engaging portion 65. When the lift part 102 gets over the first engaging part 65 , the lift part 102 is engaged with the first engaging part 65 from above through the elastic piece 121 , thereby causing the lift part 102 to move against the cap body 50 . The descent is suppressed.

On the other hand, the lock part 100 gradually moves upward following the upward movement of the lift part 102. Then, as the elastic piece 121 passes over the first engaging portion 65, the plug engaging portion 111 is separated upward from the accommodation groove 43. Moreover, in the process of the elastic piece 121 getting over the first engaging part 65, the opening stopper 112 gets over the opening suppressing part 45 upward. When the stopper 112 passes over the stopper 45, the lock part 100 is engaged with the stopper 45 from above via the stopper 112. Thereby, the lock portion 100 is held at the permissible position.

As shown in FIG. 7, with the lock portion 100 in the allowable position, the cap unit 21 is rotated in the loosening direction around the container axis O via the outer cap 55. Then, the entire cap unit 21 (cap body 50 and switching mechanism 51) rises with respect to the container body 2 as it rotates around the container axis O. As a result, the opening stopper 112 contacts the engagement protrusion 46 from below. In this state, when the cap body 50 moves further upward, the cap body 50 tries to rise with respect to the switching mechanism 51. At this time, the engagement force (frictional force) acting between the large protrusion 112a and the engagement protrusion 46 is greater than the engagement force (frictional force) acting between the elastic piece 121 and the engagement parts 65 to 67. It's getting bigger. Therefore, the switching mechanism 51 is pulled down relative to the cap body 50 via the engagement protrusion 46 and the opening stopper 112 (large protrusion 112a). As a result, before the large protrusion 112a climbs over the engagement protrusion 46 upward, the elastic piece 121 rides over each of the engagement parts 65 to 67 downward, so that the switching mechanism 51 descends with respect to the cap body 50. The switching mechanism 51 descends until the elastic piece 121 is located below the third engaging portion 67 before the screwing of the cap body 50 is released. The engagement force can be adjusted as appropriate by adjusting the protrusion amount, thickness, material, etc. of the large protrusion 112a, the engagement protrusion 46, the elastic piece 121, and the engagement parts 65 to 67.

In this state, as shown in FIG. 8, the cap unit 21 is further rotated in the loosening direction around the container axis O, and the cap unit 21 is pulled upward via the outer cap 55. Then, the opening stopper 112 (large protrusion 112a) passes over the engagement protrusion 46 upward. Then, the engagement between the plug body 20 and the switching mechanism 51 is released, and the screwing between the cap body 50 and the cap mounting portion 3a is released. As a result, the cap unit 21 is removed from the container body 2, and the spout 8 is opened (opened). Thereafter, by tilting the container body 2 or the like, the contents mixed within the container body 2 are poured out through the spout 8.

On the other hand, in order to return the cap body 50 to the closed position after pouring out the contents, the cap unit 21 is first placed over the container body 2. At this time, the opening stopper 112 (small protrusion 112b) engages with the engagement protrusion 46 from above. In this state, the cap unit 21 is rotated in the fastening direction around the container axis O via the outer cap 55. Then, the cap unit 21 descends relative to the container body 2 as it rotates around the container axis O. At this time, as shown in FIG. 9, the cap body 50, the weight part 101, and the lift part 102 move downward relative to the lock part 100, so that the bottom wall part 78 of the weight accommodating part 72 is moved relative to the base part 110. It hits me from above.

Thereafter, by further rotating the cap unit 21 in the fastening direction, the lock part 100 is pushed down via the bottom wall part 78. As a result, the cap-opening stopper 112 sequentially moves downward over the engaging protrusion 46 and the cap-opening suppressing portion 45. Then, as the cap unit 21 rotates, the plug engaging portion 111 climbs over the slope of the opening direction regulating portion 42, and then the locking portion 100 moves downward, causing the plug engaging portion 111 to move into the accommodation groove. Enter 43. As a result, the lock portion 100 reaches the restriction position and the cap body 50 reaches the closing position.

As described above, in this embodiment, the lock part 100 is provided so as to be movable in the vertical direction with respect to the stopper body 20 and the cap body 50 between the restriction position and the permissible position, and the lock part 100 is linked to the lock part 100 and is locked. A lift part 102 that is engaged with the first engaging part 65 when the part 100 is in the permissible position and restricts the downward movement of the lock part 100 with respect to the cap body 50; The structure includes a weight part 101 that pushes up the lift part 102 by movement.
According to this configuration, by moving the pouring container 10 in the vertical direction by shaking the pouring container 10 or the like, the weight portion 101 is moved upward with respect to the lock portion 100 and the lift portion 102. Then, the weight part 101 collides with the lift part 102 from below, thereby pushing up the lock part 100 and the lift part 102. As a result, the lift portion 102 moves upward over the first engaging portion 65, and the lock portion 100 moves from the restriction position to the permissible position. That is, in the pouring container 10 of this embodiment, the cap unit 21 cannot be opened unless the pouring container 10 is shaken to the extent that the weight portion 101 moves relative to the container body 2. Therefore, the user can be prompted to stir the contents, and it is possible to prevent the contents from being poured out due to forgetting to shake the pouring container 10. As a result, the contents can be poured out in a homogeneous state. Furthermore, in the pouring container 10 of this embodiment, forgetting to shake can be prevented, so convenience can be improved. Moreover, in the pouring container 10 of this embodiment, when opening the pouring container 10, it is necessary to shake the pouring container 10 with such force that the weight portion 101 moves relative to the container body 2, etc., so that the cap unit 21 may be damaged by mischief or the like. Can prevent the bottle from being opened (childproof function).
Furthermore, since the lock portion 100 moves from the restriction position to the permissible position as the contents are stirred, no separate operation is required to move the lock portion 100 to the permissible position. Therefore, when opening the pourer 1, it is possible to prevent the operability from being impaired.

In this embodiment, in the process of the lock part 100 moving from the restriction position to the permissible position, the lock part 100 contacts from below and suppresses the upward movement of the lock part 100 with respect to the plug body 20 and the cap body 50, and the lift part 102 is configured to have an opening suppressing portion 45 that allows the lock portion 100 to climb over the first engaging portion 65 upwardly.
According to this configuration, for example, when the pouring container 10 falls down and the lock portion 100 attempts to move toward the permissible position, the movement of the lock portion 100 toward the permissible position is suppressed by the opening suppressing portion 45. Ru. Thereby, it is possible to prevent the lock part 100 from suddenly moving to the permissible position, and it is possible to prevent the contents from being poured out in a non-uniform state.

In the present embodiment, a portion of the cap body 50 that is located below the first engaging portion 65 is provided with a lift portion 102 that can be climbed over while the lock portion 100 moves from the restriction position to the permissible position. The configuration is such that a second engaging portion 66 is formed.
According to this configuration, in the process of moving the lock portion 100 from the restriction position to the permissible position, it is necessary to overcome at least two engaging portions 65 and 66. In other words, the locking part 100 will not move to the permissible position unless the dispensing container 10 is shaken multiple times, which prevents variations in the mixing status of the contents when the locking part 100 moves to the permissible position. can.

In this embodiment, the first engaging part 65 and the second engaging part 66 are arranged at positions separated in the circumferential direction.
According to this configuration, when the lift section 102 moves upward, it can be suppressed from climbing over the first engaging section 65 and the second engaging section 66 all at once. Therefore, it is possible to prevent the lock portion 100 from moving to the permissible position in a state where the contents are not homogeneous.

In this embodiment, the lift portion 102 has a configuration in which a plurality of elastic pieces 121 are arranged at intervals in the circumferential direction.
According to this configuration, deformation of all the elastic pieces 121 can be suppressed when, for example, the lower engaging part (for example, the second engaging part 66) of the vertically adjacent engaging parts is climbed over. This prevents the elastic piece 121 from reaching the upper engaging part (for example, the first engaging part 65) without fully restoring after passing through the lower engaging part, and prevents the elastic piece 121 from reaching the upper engaging part (for example, the first engaging part 65), and It is possible to prevent the division from overcoming it all together. Therefore, it is possible to prevent the lock portion 100 from moving to the permissible position in a state where the contents are not homogeneous.

In this embodiment, the engagement force acting between the large protrusion 112a and the engagement protrusion 46 is larger than the engagement force acting between the elastic piece 121 and the engagement parts 65 to 67. did.
According to this configuration, when the cap is opened, the locking part 100 engages with the engagement protrusion 46 from below, so that the cap body 50 tends to rise with respect to the locking part 100 and the lift part 102. At this time, the engagement force acting between the lock part 100 (opening stopper 112) and the engagement protrusion 46 is the same as the engagement force acting between the lift part 102 (elastic piece 121) and the first engagement part 65. By being larger than this, the lift portion 102 is pulled down via the lock portion 100 as the cap body 50 moves upward. As a result, during the cap opening operation, before the large protrusion 112a climbs over the engaging protrusion 46, the elastic piece 121 rides down each of the engaging parts 65 to 67, so that the switching mechanism 51 moves over the cap body 50. descends against Therefore, when the cap unit 21 is opened, the lift section 102 can be reset to the initial state (below the third engaging section 67). Thereby, it is not necessary to return the lift section 102 to the initial state by an operation other than the opening operation of the cap unit 21, so that excellent operability can be provided.
