JP 2014-188260 A

However, in the conventional delivery container, the content protrudes from the delivery port in proportion to the amount of relative rotation between the inner cylinder portion and the outer cylinder portion, so there is a risk that the contents may be excessively discharged. If the contents are formed in a narrow shape, such as eyeliner or lip liner, or if the contents are made of a relatively soft material, the contents may break or collapse if the contents are drawn out too much.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a delivery container capable of suppressing excessive delivery of contents.

The dispensing container of the present invention comprises a nozzle cylinder extending in the vertical direction and having an upper end opening through which the contents can protrude upward; a lower cylinder part attached to the lower part of the nozzle cylinder so as to be relatively rotatable; and the nozzle cylinder. a claw-equipped cylindrical portion disposed inside the nozzle cylinder and rotatable with respect to the lower cylindrical portion and having a first locking claw projecting radially inward; a cam mechanism provided on the tubular portion and the tubular portion with claws, and for raising the tubular portion with claws by a predetermined distance relative to the lower tubular portion by rotating the tubular portion with claws relative to the lower tubular portion; a biasing member interposed between the nozzle cylinder and the claw-equipped tubular part for urging the claw-equipped cylinder part downwardly with respect to the nozzle cylinder; The contents are supported from below, and a plurality of locked teeth engaged with the first locking claws are arranged on the outer peripheral surface in the vertical direction. a locked shaft restricted from descending relative to the portion and permitted to ascend; a locked shaft restricted from ascending relative to the lower cylindrical portion and engaged with the locked tooth to permit the locked shaft to ascend; and a second locking pawl that restricts descent.

According to the present invention, when the nozzle tube is rotated with respect to the lower tube portion, the claw-equipped tube portion also rotates with respect to the lower tube portion as the nozzle tube rotates. As a result, the cam mechanism is actuated, and the claw-equipped tubular portion rises by a predetermined distance relative to the lower tubular portion.
Here, the first locking claw and the second locking claw of the tubular portion with claws are engaged with the locked teeth of the locked shaft. The locked shaft is restricted from descending with respect to the tubular portion with claws by the first locking claws. Therefore, when the tubular portion with claws rises relative to the lower tubular portion, the locked shaft also rises. On the other hand, the second locking pawl allows the locked shaft to rise and is restricted from rising with respect to the lower tubular portion. For this reason, the locked shaft moves up a predetermined distance together with the claw-equipped tubular portion relative to the lower tubular portion while allowing the second locking pawl to ride over the engaged tooth.
When the claw-attached tubular portion advances in rotation relative to the lower tubular portion and the claw-attached tubular portion reaches the upper end position relative to the lower tubular portion, the claw-attached tubular portion becomes capable of being lowered relative to the lower tubular portion. The claw-equipped cylindrical portion is biased downward with respect to the nozzle cylinder by a biasing member. Since the nozzle cylinder is provided so as not to be able to rise with respect to the lower cylinder part, the claw-equipped cylinder part descends with respect to the nozzle cylinder. At this time, the second locking pawl restricts the descent of the locked shaft. On the other hand, the first locking pawl allows the shaft to be locked to rise with respect to the tubular portion with the pawl. For this reason, the claw-equipped cylindrical portion descends by a predetermined distance with respect to the lower cylindrical portion while allowing the first locking claw to climb over the locked tooth.
As described above, the contents supported by the locked shaft can be lifted by a predetermined distance and delivered from the upper end opening of the nozzle cylinder. Therefore, it is possible to provide a delivery container capable of suppressing excessive delivery of contents.

In the dispensing container described above, the lower tubular portion and the claw-attached tubular portion are provided with restricting portions for restricting the rotation of the claw-attached tubular portion in one direction with respect to the lower tubular portion, and the cam mechanism comprises the lower tubular portion. The tubular portion with claws may be raised relative to the lower tubular portion as the tubular portion with claws rotates in the other direction with respect to the tubular portion.

ADVANTAGE OF THE INVENTION According to this invention, a user can be made to intuitively recognize the direction which rotates a nozzle cylinder, when drawing|feeding out a content.

The delivery container may further include a rotation restricting portion that allows rotation of the claw-equipped tubular portion with respect to the nozzle cylinder in the other direction and restricts rotation in the one direction.

According to the present invention, when the nozzle cylinder is rotated in one direction with respect to the lower cylinder part, the nozzle cylinder is moved to the cylinder part with claws in a state where the rotation of the cylinder part with claws with respect to the lower cylinder part is restricted by the restricting part. Relative rotation. As a result, when the nozzle cylinder is rotated in one direction with respect to the lower cylinder part, it is possible to prevent the dispensing container from being damaged by a large force acting on the restricting part.

In the delivery container described above, the engaged teeth may be arranged at a pitch that matches the predetermined distance.

According to the present invention, the cam mechanism can engage the second locking pawl with the locked tooth when the locked shaft reaches the upper end position with respect to the lower cylindrical portion. Therefore, when the claw-equipped cylindrical portion starts to descend relative to the locked shaft, it is possible to prevent the locked shaft from being dragged by the first locking claw and displaced in the vertical direction. Further, the first locking claw can be engaged with the locked tooth when the cylindrical portion with the claw reaches the lowered end position with respect to the locked shaft. Therefore, it is possible to suppress the vertical displacement of the delivered contents during use.

ADVANTAGE OF THE INVENTION According to this invention, the feeding container which can suppress the excessive delivery of the contents can be provided.

As shown in FIG. 1 , the receiving tube portion 80 includes a receiving body 81 formed in a topped cylindrical shape having a container axis O as a central axis and having a peripheral wall 82 and a top wall 83 , and a second projecting piece 87 projecting upward from the upper edge of the lower guide cylinder 85; and a second ratchet pawl 89 projecting radially inward from the second projecting piece 87. Prepare. A peripheral wall 82 of the receiving body 81 is arranged along the inner peripheral surface of the body portion 11 of the lower tubular portion 10 . The lower end portion of the peripheral wall 82 is fitted inside the main body portion 11 of the lower tubular portion 10 to restrict radial displacement with respect to the lower tubular portion 10 , and is attached to the bottom wall of the main body portion 11 of the lower tubular portion 10 upwardly. are in contact with A top wall 83 of the receiving body 81 is in contact with the lower edge of the relay tube 12 from below. Specifically, the upper surface of the top wall 83 is in contact with the lower edge of the large diameter portion 14 and the lower edge of the longitudinal rib 18 from below. As a result, the receiving tube portion 80 is restricted from ascending and descending with respect to the lower tubular portion 10 . The top wall 83 is formed with a through hole 83a through which the ratchet shaft 50 is inserted. The through-hole 83 a is formed in a non-circular cross-sectional shape corresponding to the cross-sectional shape of the ratchet shaft 50 . The lower guide tube 85 extends upward from the inner peripheral edge of the top wall 83 and is formed in a cylindrical shape having the container axis O as its central axis. The inner peripheral surface of the lower guide tube 85 matches the shape of the through hole 83a of the top wall 83 in cross section.

The second protruding piece 87 is formed so as to partially extend upward in the circumferential direction of the lower guide tube 85 . The second protruding piece 87 extends vertically with a constant width when viewed in the radial direction. The second projecting piece portion 87 is flexurally deformable in the radial direction with the connecting portion to the lower guide cylinder 85 as the base end.

The second ratchet pawl 89 protrudes from the upper end of each second projecting piece 87 . The second ratchet pawl 89 enters into the tooth grooves of the ratchet teeth 53 of the ratchet shaft 50 and engages with the ratchet teeth 53 . The second ratchet pawl 89 is formed similarly to the first ratchet pawl 49 . That is, the second ratchet pawl 89 has a locked surface 89a and a slidable contact surface 89b, and is formed so as to be able to climb over the ratchet teeth 53 downward but not upward. The second ratchet pawl 89 restricts relative downward movement of the ratchet shaft 50 by contact between the engaging surface 53 a of the ratchet tooth 53 and the engaged surface 89 a of the second ratchet pawl 89 . In addition, the second ratchet pawl 89 causes the sliding contact surface 53b of the ratchet tooth 53 to slide upward against the sliding contact surface 89b of the second ratchet pawl 89, thereby suppressing the elastic deformation of the second projecting piece portion 87. As it accompanies, it is displaced radially outward to get over the ratchet teeth 53 , thereby permitting relative upward movement of the ratchet shaft 50 . As a result, the ratchet shaft 50 is allowed to rise relative to the receiving tube portion 80 and is restricted from falling.

The receiving plate 90 includes a holding portion 91 formed in a cylindrical shape with a bottom and holding the lower end portion of the content X, and a shaft portion 92 extending downward from the bottom wall of the holding portion 91 and fitted into the concave portion 51 of the ratchet shaft 50 . And prepare. A lower end portion of the content X is fitted inside the holding portion 91 . A bottom wall of the holding portion 91 abuts the upper end surface of the ratchet shaft 50 from above. As shown in FIG. 1 , the outer diameter of the holding portion 91 is larger than the inner diameter of the hole portion 21 of the nozzle cylinder 20 . As a result, the upper edge of the holding portion 91 can contact the stepped surface 22 of the nozzle cylinder 20 from below, and the tray 90 passes through the hole 21 while allowing the content X to pass through the hole 21. is regulated.

Next, the action of the feeding container 1 described above will be described.
When using the dispensing container 1, first, the cap body 30 is removed from the lower tubular portion 10. As shown in FIG. As a result, the nozzle tube 20 is exposed.

When the nozzle tube 20 is rotated to the first side R1 in the circumferential direction with respect to the lower tube portion 10, the ratchet tube portion 40 also moves to the first side R1 in the circumferential direction with respect to the lower tube portion 10 as the nozzle tube 20 rotates. rotate to As a result, the ratchet tube portion 40 rotates to the first side R1 in the circumferential direction with respect to the relay tube 12, and the cam mechanism 60 operates. Specifically, the upper cam surface 66 of the upper cam portion 65 provided on the ratchet tube portion 40 contacts the lower cam surface 62 of the lower cam portion 61 provided on the relay tube 12, and the ratchet tube portion 40 and the relay tube contact each other. As the upper cam surface 66 and the lower cam surface 62 come into sliding contact with the relative rotation of 12, the ratchet tube portion 40 rises with respect to the lower tube portion 10 as shown in FIG.

Here, the ratchet teeth 53 of the ratchet shaft 50 are engaged with the first ratchet pawl 49 of the ratchet tube portion 40 and the second ratchet pawl 89 of the receiving tube portion 80 . The first ratchet pawl 49 restricts relative downward movement of the ratchet shaft 50 . Therefore, when the ratchet tube portion 40 rises relative to the lower tube portion 10, the ratchet shaft 50 also rises. On the other hand, the second ratchet pawl 89 allows relative upward movement of the ratchet shaft 50 and is restricted from rising relative to the lower cylindrical portion 10 . Therefore, the ratchet shaft 50 moves upward together with the ratchet tubular portion 40 relative to the lower tubular portion 10 while allowing the second ratchet pawl 89 to ride over the ratchet teeth 53 . At this time, the cam mechanism 60 raises the ratchet tube portion 40 relative to the lower tube portion 10 by a distance that matches the pitch of the ratchet teeth 53 . As a result, the ratchet shaft 50 rises relative to the lower cylindrical portion 10 by one ratchet tooth 53 .

The rotation of ratchet tube portion 40 with respect to relay tube 12 progresses, and when the distal end portions of lower cam portion 61 and upper cam portion 65 come into sliding contact with each other, ratchet tube portion 40 reaches the raised end position with respect to relay tube 12 . After that, the lower cam portion 61 can approach the outer flange 44 of the ratchet tube portion 40 and the upper cam portion 65 can approach the upper end surface of the small diameter portion 13 of the relay tube 12 . In other words, the ratchet tube portion 40 provided with the upper cam portion 65 can be lowered with respect to the relay tube 12 provided with the lower cam portion 61 . The ratchet tube portion 40 is urged downward with respect to the nozzle tube 20 by an urging member 70 . Since the nozzle cylinder 20 is provided so as not to be able to rise with respect to the lower cylinder part 10 , the ratchet cylinder part 40 descends with respect to the nozzle cylinder 20 . At this time, the second ratchet pawl 89 restricts the descent of the ratchet shaft 50 . On the other hand, the first ratchet pawl 49 allows the ratchet shaft 50 to rise relative to the ratchet tube portion 40 , that is, allows the ratchet tube portion 40 to descend relative to the ratchet shaft 50 . Therefore, as shown in FIG. 7, the ratchet tube portion 40 descends by one ratchet tooth 53 with respect to the lower tube portion 10 while allowing the first ratchet pawl 49 to ride over the ratchet tooth 53 by one tooth.

As described above, the contents X supported by the ratchet shaft 50 can be raised by one tooth of the ratchet teeth 53 and delivered from the upper end opening 20 a of the nozzle cylinder 20 . By the way, when the ratchet shaft 50 is raised by rotating the nozzle tube 20 , the biasing force of the biasing member 70 acts on the cam mechanism 60 to generate rotational resistance against the nozzle tube 20 . Therefore, each time the upper cam portion 65 rides over the lower cam portion 61 and the ratchet shaft 50 rises by one tooth of the ratchet teeth 53 due to the rotating operation of the nozzle tube 20, the rotational resistance acting on the nozzle tube 20 increases or decreases. When the nozzle tube 20 is rotated to the second side R2 in the circumferential direction with respect to the lower tube portion 10, the upper restricting surface 67 of the upper cam portion 65 comes into contact with the lower restricting surface 63 of the lower cam portion 61. relative rotation of the ratchet tube portion 40 and the relay tube 12 is restricted.

As described above, according to the present embodiment, the content X can be delivered from the nozzle cylinder 20 by one tooth of the ratchet teeth 53 . Therefore, according to the dispensing container 1, it is possible to prevent the content X from being excessively supplied.

In addition, since the rotational resistance acting on the nozzle tube 20 increases or decreases each time the ratchet shaft 50 rises by one ratchet tooth 53 due to the rotating operation of the nozzle tube 20, the content X is delivered by one tooth of the ratchet tooth 53. A click feeling can be given to the user who touches the lower cylinder part 10 and the nozzle cylinder 20 each time. Therefore, excessive rotation of the nozzle tube 20 can be suppressed, and excessive ejection of the contents X can be suppressed.

Further, when the nozzle tube 20 is rotated to the second side R2 in the circumferential direction with respect to the lower tube portion 10, when the upper cam portion 65 and the lower regulating surface 63 of the lower cam portion 61 come into contact with each other, there is no more pressure. Since the rotation of the nozzle tube 20 is restricted, the user can intuitively recognize the direction in which the nozzle tube 20 is to be rotated when the content X is delivered.

The pitch of the ratchet teeth 53 matches the distance by which the cam mechanism 60 raises the ratchet tubular portion 40 relative to the lower tubular portion 10 . According to this configuration, the cam mechanism 60 can engage the second ratchet pawl 89 with the ratchet teeth 53 when the ratchet shaft 50 reaches the upper end position with respect to the lower tubular portion 10 . Therefore, when the ratchet tube portion 40 starts to descend relative to the ratchet shaft 50, it is possible to prevent the ratchet shaft 50 from being dragged by the first ratchet pawl 49 and being displaced downward. Further, the first ratchet pawl 49 can be engaged with the ratchet teeth 53 when the ratchet tube portion 40 reaches the lowered end position with respect to the ratchet shaft 50 . Therefore, it is possible to suppress the vertical displacement of the delivered contents X during use.

(Second embodiment)
Next, a second embodiment of the delivery container 1A according to the present invention will be described with reference to the drawings. The second embodiment differs from the first embodiment in that the ratchet tube portion 40 is provided so as to be non-rotatable with respect to the nozzle tube 20 only on the second side R2 in the circumferential direction. Configurations other than those described below are the same as those of the first embodiment. In this embodiment, of the circumferential directions, the clockwise direction viewed from above is defined as the first side R1, and the opposite direction is defined as the second side R2.

As shown in FIGS. 8 and 9, the delivery container 1A has a rotary ratchet mechanism that allows rotation of the ratchet tube portion 40 relative to the nozzle tube 20 on the first side R1 in the circumferential direction and restricts rotation on the second side R2 in the circumferential direction. 100 (rotation restrictor) is provided. As a result, the ratchet tube portion 40 cannot rotate with respect to the nozzle tube 20 only on the second side R2 in the circumferential direction. However, the ratchet tube portion 40 may be provided so as to idle within a range of less than 360° on the second side R2 in the circumferential direction with respect to the nozzle tube 20 . The rotary ratchet mechanism 100 includes an engaging protrusion 27 provided on the inner peripheral surface of the nozzle tube 20 and an engaging arm 48 provided on the ratchet tube portion 40 .

The nozzle cylinder 20 is provided with engaging projections 27 in place of the fitting ribs 26 of the first embodiment. A plurality of engaging protrusions 27 (six in the illustrated example) protrude from the inner peripheral surface of the nozzle cylinder 20 . The plurality of engaging protrusions 27 are arranged at intervals in the circumferential direction. The engaging protrusion 27 has an engaging surface 27a facing the first side R1 in the circumferential direction and a non-engaging surface 27b inclined with respect to the circumferential direction and facing inward in the engaging direction on the second side R2 in the circumferential direction. have. The planar view shape of the engaging projection 27 is formed such that the width in the circumferential direction gradually narrows from the outer side toward the inner side in the engaging direction.

The ratchet tube portion 40 includes a collar portion 46 and an engaging arm 48 instead of the outer flange 44 of the first embodiment. A plurality of flanges 46 (two in the illustrated example) are provided in the circumferential direction and are arranged around the container axis O at equal angular intervals. The flange portion 46 protrudes radially outward from a vertical intermediate portion of the upper guide tube 41 . The collar portion 46 extends in an arc shape along the circumferential direction. The outer peripheral surface of the collar portion 46 is close to the engaging projection 27 of the nozzle cylinder 20 so as to be slidably contactable. A lower end portion of the biasing member 70 is in contact with the upper surface of the flange portion 46 from above. An upper cam portion 65 protrudes from the lower surface of the flange portion 46 . The engaging arms 48 are provided in the same number as the collar portions 46 in the circumferential direction, and are arranged around the container axis O at equal angular intervals. The engagement arm 48 extends in an arc shape along the circumferential direction. The end portion of the engagement arm 48 on the first circumferential side R<b>1 continues to the end portion of the flange portion 46 on the second circumferential side R<b>2 . The engaging arm 48 is separated from the outer peripheral surface of the upper guide tube 41, and is elastically deformable such that the distal end portion of the second side R2 in the circumferential direction is displaced radially inward. A distal end surface 48 a that faces the second side R<b>2 in the circumferential direction and engages with the engaging surface 27 a of the engaging protrusion 27 is formed at the distal end portion of the engaging arm 48 .

Next, the operation of the feeding container 1A described above will be described.
When the nozzle tube 20 is rotated to the first side R1 in the circumferential direction with respect to the lower tube portion 10, the tip surface 48a of the engaging arm 48 of the ratchet tube portion 40 engages the engaging surface 27a of the engaging projection 27 of the nozzle tube 20. to engage. Therefore, the ratchet tube portion 40 rotates together with the nozzle tube 20 and rotates to the first side R1 in the circumferential direction with respect to the lower tube portion 10 . As a result, as in the first embodiment, the cam mechanism 60 is actuated to raise the ratchet cylinder portion 40 by a predetermined distance with respect to the lower cylinder portion 10, and the contents X are drawn out from the upper end opening 20a of the nozzle cylinder 20. be

On the other hand, when the nozzle tube 20 is rotated to the second side R2 in the circumferential direction with respect to the lower tube portion 10, the engaging projection 27 of the nozzle tube 20 is moved to the distal end portion of the engaging arm 48 of the ratchet tube portion 40 in the circumferential direction. , the ratchet tube portion 40 rotates together with the nozzle tube 20. As shown in FIG. As the nozzle tube 20 rotates relative to the lower tube portion 10 , the upper restricting surface 67 of the upper cam portion 65 comes into contact with the lower restricting surface 63 of the lower cam portion 61 . Rotation is restricted. Then, the engaging arm 48 of the ratchet tube portion 40 slides on the non-engaging surface 27b of the engaging protrusion 27 of the nozzle tube 20 and climbs over the engaging protrusion 27. As shown in FIG. As a result, the nozzle tube 20 rotates relative to the ratchet tube portion 40 while the rotation of the ratchet tube portion 40 with respect to the lower tube portion 10 is restricted by the lower cam portion 61 and the upper cam portion 65 . Therefore, when the ratchet tube portion 40 is rotated to the second side R2 in the circumferential direction with respect to the lower tube portion 10, a large force acts on the lower cam portion 61 and the upper cam portion 65, and the dispensing container 1A is damaged. can be suppressed.

It should be noted that the present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications are conceivable within its technical scope.
For example, in the above-described embodiment, the contents X are lifted by rotating the nozzle tube 20 to the first side R1 in the circumferential direction with respect to the lower tube portion 10, but the present invention is not limited to this. That is, the contents may be lifted by rotating the nozzle tube to the second side R2 in the circumferential direction with respect to the lower tube portion.

In addition, in the above embodiment, the ratchet shaft 50 is provided so as to be non-rotatable with respect to the ratchet tube portion 40 and rotatable with respect to the lower tube portion, but it is not limited to this. For example, the ratchet shaft may be provided to be rotatable with respect to the ratchet tube portion and non-rotatable with respect to the lower tube portion. In this case, the second ratchet pawl can be provided integrally with the lower cylindrical portion. By providing the ratchet teeth on the entire outer peripheral surface of the portion of the ratchet shaft that can be engaged with the first ratchet pawl, even if the ratchet shaft and the ratchet cylindrical portion rotate relative to each other, the first ratchet pawl does not engage the ratchet teeth. can be engaged. The ratchet shaft may be provided rotatably with respect to both the ratchet tube portion and the lower tube portion.

Further, in the above-described embodiment, both the lower cam portion 61 and the upper cam portion 65 that constitute the cam mechanism 60 are provided with cam surfaces. That is, both the lower cam portion 61 and the upper cam portion 65 function as cam bodies and also as followers for the other. However, the present invention is not limited to this, and one of the lower cam portion 61 and the upper cam portion 65 may be replaced with a convex structure that does not have a cam surface and is in sliding contact with the cam surface of the other cam portion.

In the above-described embodiment, the lower cam portion 61 and the upper cam portion 65 are provided with the lower restricting surface 63 and the upper restricting surface 67, so that the rotation of the second side R2 in the circumferential direction of the nozzle tube 20 with respect to the lower tube portion 10 is controlled. regulated, but not limited to. Even if at least one of the lower cam portion and the upper cam portion has an inclined surface (cam surface) facing the first side R1 in the circumferential direction and an inclined surface (cam surface) facing the second side R2 in the circumferential direction. good. As a result, the ratchet tubular portion can be lifted relative to the lower tubular portion 10 regardless of which direction the nozzle tube 20 is rotated relative to the lower tubular portion 10 . Therefore, it is possible to provide a dispensing container capable of dispensing contents even if the nozzle cylinder 20 is rotated in any direction with respect to the lower cylinder part 10 .

Moreover, in the above-described embodiment, the ratchet shaft 50 supports the content X from below through the tray 90, but the present invention is not limited to this. The ratchet shaft may be provided so as to be vertically movable integrally with the contents, and may directly support the contents from below.

Moreover, in the above-described embodiment, the pair of planar cutouts 52 are formed on the outer peripheral surface of the ratchet shaft 50, but the present invention is not limited to this. The ratchet shaft may be formed so as not to rotate relative to the ratchet tube portion and the receiving tube portion. For example, a notch may be provided at only one location in the circumferential direction to form a D-cut surface, or notches may be provided at three or more locations in the circumferential direction. Also, the notch may be formed in a curved shape.

In the above embodiment, the distance by which the cam mechanism 60 lifts the ratchet tube portion 40 with respect to the lower tube portion 10 is matched with the pitch of the ratchet teeth 53, but the present invention is not limited to this. The distance by which the cam mechanism 60 lifts the ratchet tube portion 40 relative to the lower tube portion 10 may be greater than the pitch of the ratchet teeth. Accordingly, by rotating the nozzle tube 20 with respect to the lower tube portion 10, the contents can be delivered by at least one pitch of the ratchet teeth.

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the scope of the present invention.
