Japanese Patent No. 3759428

  However, the above engagement is generally realized by a configuration in which an engaged portion provided on the cap is undercut fitted (fitted with a catch due to a step) to an engaging portion provided on the movable stopper. Therefore, when the engaged portion of the cap is disengaged from the engaging portion of the movable plug, the cap is disengaged so as to repel each other, so that the movable plug, which has been raised by the reaction force, may be pushed down again.

  Such lowering of the movable plug prevents the flow path formation realized by reliably pulling up the movable plug, so that the movable plug is lifted at the same time as opening the cap and opening the movable plug at the same time. A complicated operation is forced on the user.

  On the other hand, a method of restricting the vertical movement of the movable plug by giving resistance to the movable plug with a shell member is also conceivable. A new problem arises that the up-and-down movement) is impaired.

  An object of the present invention is to pull up the movable plug simultaneously with the removal of the cap by detachably engaging the second engagement portion provided on the back side of the cap with the first engagement portion provided on the movable plug. An object of the present invention is to provide a novel dispensing container that is easy to use and enables reliable dispensing by a single operation without forcing the user to perform complicated operations.

The dispensing container of the present invention has a container body that has a mouth portion and is filled with contents inside, and
A dispenser having a shell member attached to the mouth of the container body, and capable of pulling up the movable stopper exposed from the shell member;
It has a top wall arranged on the upper side of the dispenser, and includes a cap that is detachably attached to the mouth of the container body.
When the cap is closed from the top wall of the cap, the peripheral wall surrounding the movable plug is suspended, and the inner surface of the peripheral wall is extended to the first engagement portion that bulges from the outer surface of the movable plug when the cap is closed. A second container that is detachably engaged, and is a dispensing container that raises the movable stopper simultaneously with the removal of the cap,
When removing the cap, the second engagement portion is connected to the tip portion where the first engagement portion rides up and contacts, and the position where the engagement with the first engagement portion is released after the tip portion. It has a guide part which one engagement part contacts, and the contact width of the peripheral direction in this guide part is made to become smaller than the contact width of the peripheral direction in a tip part.

  When the contact surface of the guide part is configured to be smaller than the contact area of the tip part, the guide part may be tapered from the tip part along the axial direction, or the tip part may be narrower than the tip part in the axial direction. Extending in parallel along the axis, or inclined with respect to the axial direction.

  Further, the second engaging portion is configured such that when the cap is removed, the position where the first engaging portion gets over the second engaging portion and the mutual engagement is released differs along the circumferential direction of the peripheral wall. Thus, the timing at which the engagement is released can be varied along the circumferential direction of the peripheral wall.

  In order to change the timing at which the engagement is released, the position where the first engagement portion gets over the second engagement portion and the mutual engagement is released differs along the circumferential direction of the peripheral wall. However, according to the present invention, it may be configured to draw a spiral trajectory along the circumferential direction of the peripheral wall.

  As the second engaging portion provided on the cap, a rib bulged around the axis along the inner surface of the peripheral wall suspended from the top wall so as to surround the movable stopper, or the axis along the inner surface of the peripheral wall. Examples include a plurality of ribs that are bulged around the periphery.

  However, when the second engaging portion is an annular rib continuous along the inner surface of the peripheral wall, or when the second engaging portion bulges around the axis along the inner surface of the peripheral wall, the movable stopper is provided. Of course, it arrange | positions so that engagement with a 1st engaging part may be implement | achieved reliably. In addition, in the case where the second engagement portion is constituted by a plurality of ribs, the interval between the ribs can be adjusted as appropriate.

  On the other hand, the first engaging portion provided on the movable stopper also has an annular bulge around the tip spout (axis) or a bulge with a space around the tip spout (axis) Etc. In particular, when bulging around the tip spout (axis) with an interval, it is of course arranged so that the engagement with the second engagement portion provided on the cap is reliably realized.

  As long as the cap is configured to be removed upward from the container body, the cap may be screwed or detachably undercut fitted to the container body.

  In the present invention, when the second engaging portion is removed from the cap, the tip portion where the first engaging portion rides up and contacts, and the position where the second engaging portion is released from the first engaging portion connected to the tip portion. The first engaging portion is in contact with the guide portion, and the circumferential contact width at the guide portion is smaller than the circumferential contact width at the tip portion. When the first engaging part of the movable plug gets over the second engaging part of the cap and is disengaged from each other, the friction generated during the removal of the cap is released before the release of the engagement. The power can be reduced in advance.

  For this reason, a phenomenon in which the first engagement portion is flipped downward by the second engagement portion due to the reaction force resulting from the releasing operation of the engagement can be suppressed. It is not pushed down again by being played downward by the joint.

  That is, according to the present invention, even if the movable plug is pulled up simultaneously with the removal of the cap by engaging the second engaging portion of the cap with the first engaging portion of the movable plug, the cap can be moved along with the release of the engagement. Since the plug is not pushed down again, it is possible to reliably dispense by one operation without forcing a complicated operation to cause the user to lift the movable plug again. Therefore, according to the present invention, it is possible to provide a novel dispensing container that is easy to use.

  Further, regarding the second engagement portion provided on the cap, when the cap is removed, the position where the first engagement portion provided on the movable stopper gets over the second engagement portion and the mutual engagement is released is movable. In addition to reducing the frictional force by the guide portion, if the timing for releasing the engagement is made different along the circumferential direction of the peripheral wall so as to be different along the peripheral direction of the peripheral wall surrounding the stopper, After the movable plug is lifted with the lifting of the cap, when the first engaging portion of the movable plug gets over the second engaging portion of the cap and the mutual engagement is released, the first engaging portion is Since the phenomenon of being flipped downward by the two engaging portions is dispersed in time series, it is possible to further suppress the pressing of the movable plug caused by the first engaging portion being flipped downward by the second engaging portion. it can.

  In addition, if a plurality of ribs arranged around the axis along the inner surface of the peripheral wall so as to surround the movable stopper are adopted as the second engaging portion, the friction force generated during the removal of the cap is effective. Therefore, it is effective to suppress the pressing of the movable stopper.

  In this embodiment, when the mounting cylinder 11a is mounted on the mouth portion 21, an annular locking projection 22 is provided around the axis O on the outer surface of the mouth portion 21, and the locking projection 22 is provided on the inner surface of the mounting cylinder 11a. It fixes by making the provided protrusion 11g fit undercut.

Further, the movable plug 13 at its distal end spout A ₂ around the lip 13h is provided as a first engaging portion that bulges in an annular outwardly. In this embodiment, the lip 13h is detachably undercut fitted to a plurality of ribs 31a, which are the second engaging portions 31 provided on the inner surface of the peripheral wall 33 suspended from the back side of the cap 30, as shown in FIG. In addition, the movable stopper 13 is pulled up simultaneously with the removal of the cap 30.

  As shown in FIG. 1, the cap 30 has a top wall 32 arranged on the upper side of the dispenser 10. From the top wall 32, as shown in FIG. A peripheral wall 33 that surrounds the movable stopper 13 hangs down integrally.

  3 (a) and 3 (b) are a main part development view showing the peripheral wall 33 having the rib 31a as the first form in a state of being developed from the inside thereof, and the rib 31 is partly three-dimensional around the axis O. It is principal part sectional drawing shown in FIG.

  As shown in FIG. 3 (a), the rib 31a bulges a part of the inner surface of the peripheral wall 33 with an interval around the axis O (the ribs 31a on the left and right of the drawing are combined into one rib 31a). Configure). The rib 31a has a locking end e that hooks the lip 13h detachably from below and locks the lip 13h.

  Thereby, as shown in FIG. 1, the rib 31a is detachably undercut fitted to the lip 13h of the movable plug 13 when the cap 30 is closed.

  Further, the tip end portion 31b on which the lip 13h climbs and contacts is connected to the locking end e. As shown in FIG. 3 (b), the leading end portion 31b is connected to a guiding portion 31c that is in contact with the leading end portion 31b up to a position 31e where the engaging with the lip 13h is released. The guide part 31c is narrower than the tip part 31b and extends in the vertical direction along the axis O.

  Thereby, as shown in FIG. 3A, the rib 31a is formed in a T shape by the tip portion 31b and the guide portion 31c. That is, in FIG. 4 (a), as shown by way of example in one rib 31a, the contact width Wc in the circumferential direction (around the axis O) in the guide portion 31c is the circumferential width (around the axis O) in the tip portion 31b. It is configured to be smaller than the contact width Wb.

  Thereby, the position where the lip 13h gets over the rib 31a and the engagement with the rib 31 is released becomes the lower end position 31e of the guide portion 31c.

More specifically, the second engagement portion 31 according to the present invention is intermittently spaced around the axis O along the inner surface of the peripheral wall 33 with intervals L _{1 to} L ₄ as shown in FIG. It consists of a plurality of provided ribs 31a. In this embodiment, the intervals L _{1 to} L ₄ are made equal, but these intervals L _{1 to} L ₄ can be set as appropriate.

  According to such a configuration, when the cap 30 is pulled up while being rotated, the lip 13h first climbs over the engaging end e of the rib 31a and rides on the tip end portion 31b, and then touches more than the tip end portion 31b. By moving to the lower end position 31e while sliding on the small guide part 31c, when the engagement at the rib 31a is released, the movable plug 13 is pulled up to the top dead center.

  In this embodiment, the rib 31a has a tip portion 31b where the lip 13h rides and comes into contact, and a guide portion 31c where the lip 13h comes into contact with the tip portion 31b to the lower end position 31e. Since the contact width Wc is configured to be smaller than the contact width Wb of the distal end portion 31b, the frictional force generated during the removal of the cap 30 is removed before the lip 13h gets over the rib 31a and releases the engagement. It can be lowered in advance.

  For this reason, the reaction force resulting from the frictional force can suppress the phenomenon in which the lip 13h is flipped downward by the rib 31a. Therefore, when the lip 13h is flipped downward by the rib 31a, the movable plug 13 is again released. It will not be pushed down.

  That is, according to this embodiment, even if the rib 31a is engaged with the lip 13h and the movable plug 13 is pulled up simultaneously with the removal of the cap 30, the movable plug 13 is not pushed down again with the release of the engagement. Therefore, reliable dispensing can be performed by a single operation without forcing the user to raise the movable stopper 13 again. Therefore, according to this embodiment, it is possible to provide a new dispensing container that is easy to use.

  Each locking end e of the rib 31a has the same height He from the lower end 33e of the peripheral wall 33 as shown in FIG. That is, in this embodiment, when the cap 30 is tightened, the ribs 31a are locked at the same timing. Each lower end 31e of the rib 31a also has the same height H from the lower end 33e of the peripheral wall 33 as shown in FIG. That is, in this embodiment, when removing the cap 30, the engagement of each rib 31a is released at the same timing.

  4 (a) and 4 (b) are main part development views showing the peripheral wall 33 having the ribs 31 as the second form in an expanded state, and a part of the ribs 31 around the axis O. It is principal part sectional drawing shown in three dimensions. In the following description, the same parts as those in FIGS.

  In this embodiment, as shown in FIG. 4 (a), the tip portion 31b and the guide portion 31c are T-shaped so that the circumferential contact width Wc at the guide portion 31c is equal to the circumferential contact width at the tip portion 31b. In addition to being configured to be smaller than Wb, the guide part 31c is inclined with respect to the direction of the axis O along the inner surface of the peripheral wall 33.

  In the first and second embodiments described above, the tip portion 31b and the guide portion 31c are configured as the same plane by equalizing the thickness (projection height) of the tip portion 31b and the guide portion 31c. However, a step may be formed between the tip portion 31b and the guide portion 31c, or the guide portion 31c may be inclined so as to approach the inner surface of the peripheral wall 33 toward the lower end 33e of the peripheral wall 33.

  Next, the operation of this embodiment will be described.

  In this embodiment, in order to remove the cap 30 from the state shown in FIG. 1, when the cap 30 is turned and pulled up, the movable plug 13 also moves while the rib 31 a provided on the cap 30 is caught on the lip 13 h of the movable plug 13. Pull up together. When the cap 30 is further rotated, the lip 13h passes over the engaging end e of the rib 31a and rides on the tip portion 31b, and slides on the guide portion 31c having a smaller contact area than the tip portion 31b.

  When the cap 30 is further rotated, the lip 13h reaches the lower end position 31e while sliding on the guide portion 31c having a small contact area, so that the hook with the rib 31a is released. Therefore, finally, as shown in FIG. 2, after the movable stopper 13 is pulled up to the top dead center, the movable stopper 13 is not pushed down when the engagement is released, so that the cap 30 is a container. Detach from the mouth 21 of the main body 20.

In this pulling, the movable plug 13, as shown in FIG. 2 causes through the feed opening A ₁ to the tip spout A _2. As a result, if the container body 20 is inverted and shaken so that the tip discharge port A ₂ faces downward, the contents of the container body 20 are transferred from the mouth portion 21 through the supply hole A ₁ to the tip spout A _2. Can be dispensed from.

  According to the present invention, the number of the ribs 31 a related to the cap 30 may be at least two. However, if the number of the ribs 31 a is increased, the cap 30 can be firmly engaged with the movable plug 13. .

  Further, in this embodiment, when the movable plug 13 is pushed down, when the cap 30 is tightened, as shown in FIG. 1, the rib 31a provided on the cap 30 pushes down the tip 13e of the movable plug 13 via the lip 13h. It is configured as follows.

  Furthermore, the rib 31a is arranged such that when the cap 30 is removed, the position 31e where the lip 13h gets over and the mutual engagement is released is made different along the circumferential direction of the peripheral wall 33 and the engagement is released. Can be configured to vary along the circumferential direction of the peripheral wall 33.

  FIGS. 5 (a) and 5 (b) are main part development views showing the peripheral wall 33 having the rib 31 as the third form developed from the inside thereof, and the rib 31 is partly three-dimensional around the axis O. FIG. It is principal part sectional drawing shown in FIG.

As shown in FIG. 5A, the third form of the rib 31a includes four first ribs 31a ₁ , second ribs 31a ₂ , third ribs 31a ₃ and fourth ribs 31a ₄ from the left side of the drawing. It consists of two ribs.

As shown in FIG. 5A, the ribs 31a _{1 to} 31a ₄ are provided intermittently at intervals L _{1 to} L ₄ around the axis O along the inner surface of the peripheral wall 33, respectively. In this embodiment, the intervals L _{1 to} L ₄ are made equal, but these intervals L _{1 to} L ₄ can be set as appropriate.

The lower end position 31e ₁ of the first rib 31a has the highest height H ₁ from the lower end 33e of the peripheral wall 33, and then gradually decreases in the circumferential direction (left side in the drawing) of the peripheral wall 33. That is, the lower end position 31e ₂ of the second rib 31a ₂ is lower in height H ₂ is than the first rib _{31a 1 (H 2 <H 1} ), the lower end position 31e ₃ of the third rib 31a _3, the high is H ₃ is lower than the second rib _{31a 2 (H 3 <H 2} ), further, the lower end position 31e ₄ of the fourth rib 31a _4, the height H ₄ is lower than the third rib 31a ₃ (H ₄ <H ₃ )

Accordingly, the lower end position 31e ₁ ~31e ₄ ribs 31a ₁ ~31a ₄ according to the present embodiment, at the inner side of the peripheral wall 33, so as to draw a spiral locus of the axis O around along the circumferential direction of the peripheral wall 33 Will be configured.

According to such a configuration, when the cap 30 is rotated increases, in conjunction with this, the lip 13h First, although the engagement of the first rib 31a ₁ is released, this time, the lip 13h is still remaining It is held by the ribs 31a _{2 to} 31a ₄ . Further, when the cap 30 is rotated, the engagement with the second rib 31a ₂ is released. At this time, the remaining third rib 31a ₃ and fourth rib 31a ₄ still hold the lip 13h.

Hereinafter, until the cap 30 is removed, the engagement with the third rib 31a ₃ and the engagement with the fourth rib 31a ₄ are sequentially released at different timings. As a result, the engagement with the fourth rib 31a ₄ is released. When released, the movable stopper 13 is pulled up to the top dead center.

In this embodiment, in addition to the frictional force is reduced by the guide portions 31c ₁ ~31c _4, respectively lower end position 31e ₁ ~31e ₄ of a plurality of ribs 31a ₁ ~31a ₄ provided in the cap 30, the peripheral of the peripheral wall 33 Since the timing at which the engagement is released is changed along the circumferential direction of the peripheral wall 33 so as to be different along the direction, the rib 31 a is formed after the movable plug 13 is pulled up along with the lifting of the cap 30. When the lip 13h gets over the lip 13h, the phenomenon that the lip 13h is flipped downward by the rib 31a is dispersed in time series, and thus the lip 13h is flipped downward by the rib 31a. The pushed down of the movable stopper 13 can be further suppressed.

  In addition, as in the present embodiment, as the second engaging portion 31, if a plurality of ribs 31a arranged around the axis O along the inner surface of the peripheral wall 33 so as to surround the movable plug 13 are employed, Since the frictional force generated during the removal of the cap 30 can be effectively suppressed, it is effective for suppressing the pressing of the movable plug 13.

Incidentally, the engaging end e ₁ to e ₄ of the ribs 31a ₁ ~ rib 31a _4, as shown in FIG. 5 (a), in which the height of He from the lower end 33e of the peripheral wall 33 and the same. That is, in this embodiment, when the cap 30 is tightened, the ribs 31a _{1 to} 31a ₄ are locked at the same timing.

In addition, in this embodiment, the heights H _{1 to} H ₄ of the lower end position e of the rib 31a are defined by changing the dimensions of the guide portions 31c _{1 to} c ₄ with respect to the axis O. More specifically, the dimensions of the guide portions 31c _{1 to} c ₄ with respect to the axis O are extended so as to be inversely proportional to the heights H _{1 to} H ₄ of the lower end position e of the rib 31a. In this case, a reliable fitting strength can be ensured until the engagement of the fourth rib 31a ₄ is released.

The above description shows only one embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, the lip of the movable stopper is provided around the tip, but the position can be changed as appropriate. In addition, the number of ribs arranged on the cap and the arrangement interval thereof can be appropriately changed.
