Description

The present invention relates to a feeding container.

Conventionally, for example, as shown in Patent Document 1 below, the inner cylinder portion and the inner cylinder portion are relatively rotatably exteriord, and extend from the inner cylinder portion toward one side along the container axial direction. The container body having the outer cylinder portion and the inner cylinder portion are arranged so as to be relatively rotatable with respect to the inner cylinder portion in a state where the relative rotation between the container body and the outer cylinder portion is restricted. A holding member that moves forward and backward in the container axial direction as the outer cylinder portion rotates with respect to the container, and the holding member includes a main body portion that holds the contents located in the outer cylinder portion from the other side along the container axial direction. It is a feeding container provided with a protruding portion that protrudes from the main body toward the other side and is inserted into the inner cylinder portion. The protruding portion is formed in a tubular shape, and the outer peripheral surface of the protruding portion is inside. There is known a feeding container in which a male threaded portion to be screwed into a female threaded portion formed on the inner peripheral surface of the tubular portion is formed.
In this feeding container, the inner cylinder portion and the outer cylinder portion are relatively rotated to advance and retreat the holding member in the container body in the direction of the container axis, so that the contents can be seen and removed from the feeding port of the container body. Adjust the amount of protrusion of the contents from the delivery port.

Japanese Unexamined Patent Publication No. 2014-188260

However, in the conventional feeding container, the content protrudes from the feeding port in proportion to the relative rotation amount between the inner cylinder portion and the outer cylinder portion, so that there is a possibility that the content is excessively fed. When the content is formed into a thin shape such as an eyeliner or a lip liner, or when the content is a relatively soft material, excessive feeding of the content may cause the content to break or collapse.

The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a feeding container capable of suppressing excessive delivery of contents.

The feeding container of the present invention has a nozzle cylinder having an upper end opening that extends in the vertical direction and allows the contents to protrude upward, a lower cylinder portion that is rotatably mounted on the lower portion of the nozzle cylinder, and the nozzle cylinder. A claw-attached cylinder portion that is arranged inside the nozzle cylinder, is rotatably provided with respect to the nozzle cylinder and is rotatably provided with respect to the lower cylinder portion, and has a first locking claw that protrudes inward in the radial direction, and the lower portion. A cam mechanism provided on the cylinder portion and the claw-attached cylinder portion, which raises the claw-attached cylinder portion by a predetermined distance with respect to the lower cylinder portion by rotating the claw-attached cylinder portion with respect to the lower cylinder portion. , The urging portion formed integrally with the claw-attached cylinder portion and urging the claw-attached cylinder portion downward with respect to the nozzle cylinder, and the contents are inserted inside the claw-attached cylinder portion. A plurality of locked teeth that are supported from below the contents and engaged with the first locking claw are arranged in the vertical direction on the outer peripheral surface, and the first locking claw restricts the descent with respect to the claw-attached cylinder portion. The locked shaft that was allowed to rise and the lower cylinder portion was restricted from rising, and engaged with the locked tooth to allow the locked shaft to rise and regulated to descend. It is characterized by having two locking claws.

According to the present invention, when the nozzle cylinder is rotated with respect to the lower cylinder portion, the claw-attached cylinder portion also rotates with respect to the lower cylinder portion as the nozzle cylinder rotates. As a result, the cam mechanism operates, and the claw-attached cylinder portion rises by a predetermined distance against the urging force of the urging portion with respect to the lower cylinder portion.
Here, the first locking claw and the second locking claw of the claw-attached cylinder portion are engaged with the locked tooth of the locked shaft. The locked shaft is restricted from descending with respect to the claw-attached cylinder portion by the first locking claw. Therefore, when the claw-attached cylinder portion rises with respect to the lower cylinder portion, the locked shaft also rises. On the other hand, the second locking claw allows the locked shaft to rise and is restricted from rising with respect to the lower cylinder portion. Therefore, the locked shaft rises by a predetermined distance with respect to the lower cylinder portion together with the claw-attached cylinder portion while causing the second locking claw to get over the locked teeth.
When the rotation of the claw-attached cylinder portion with respect to the lower cylinder portion progresses and the claw-attached cylinder portion reaches the rising end position with respect to the lower cylinder portion, the claw-attached cylinder portion can be lowered with respect to the lower cylinder portion. The claw-attached cylinder portion is urged downward with respect to the nozzle cylinder by the urging portion. Since the nozzle cylinder is provided so as not to be able to rise with respect to the lower cylinder portion, the claw-attached cylinder portion descends with respect to the nozzle cylinder portion. At this time, the second locking claw regulates the descent of the locked shaft. On the other hand, the first locking claw allows the locked shaft to rise with respect to the claw-attached cylinder portion. Therefore, the claw-attached cylinder portion descends by a predetermined distance with respect to the lower cylinder portion while causing the first locking claw to get over the locked tooth.
As described above, the content supported by the locked shaft can be raised by a predetermined distance, and the content can be fed out from the upper end opening of the nozzle cylinder. Therefore, it is possible to provide a feeding container capable of suppressing excessive feeding of the contents.
Further, since the claw-attached cylinder portion and the urging portion can be made into a single member, the number of parts can be reduced as compared with the case where the claw-attached cylinder portion and the urging portion are separately formed.

In the above-mentioned feeding container, the second locking claw may be formed integrally with the lower cylinder portion.

According to the present invention, the number of parts can be reduced as compared with the case where the lower cylinder portion and the second locking claw are separately formed.

According to the present invention, it is possible to provide a feeding container capable of suppressing excessive feeding of the contents.

The rotary ratchet mechanism 100 rotates the ratchet cylinder portion 40 with respect to the nozzle cylinder 20 to the second side R2 in the circumferential direction by engaging the engaging surface 23a of the engaging protrusion 23 with the tip surface 71a of the urging portion 70. It is regulated. Further, in the rotary ratchet mechanism 100, the protruding portion 71 of the urging portion 70 is brought into sliding contact with the non-engaging surface 23b of the engaging protrusion 23, so that the protruding portion 71 is radially deformed with elastic deformation of the urging portion 70. Since the ratchet cylinder portion 40 is displaced inward to get over the engaging protrusion 23, the ratchet cylinder portion 40 is allowed to rotate to the first side R1 in the circumferential direction with respect to the nozzle cylinder 20. As a result, the ratchet cylinder portion 40 is restricted from rotating only on the second side R2 in the circumferential direction with respect to the nozzle cylinder 20. However, the ratchet cylinder portion 40 may be provided so as to idle on the second side R2 in the circumferential direction with respect to the nozzle cylinder 20 within a range of less than 360 °.

When the nozzle cylinder 20 is rotated to the first side R1 in the circumferential direction with respect to the lower cylinder portion 10, the ratchet cylinder portion 40 also rotates with the rotation of the nozzle cylinder 20 to the first side R1 in the circumferential direction with respect to the lower cylinder portion 10. Rotate to. As a result, the ratchet cylinder portion 40 rotates on the first side R1 in the circumferential direction with respect to the relay portion 12, and the cam mechanism 60 operates. Specifically, the upper cam surface 66 of the upper cam portion 65 provided on the ratchet cylinder portion 40 comes into contact with the lower cam surface 62 of the lower cam portion 61 provided on the lower cylinder portion 10, and the ratchet cylinder portion 40 and the lower As the upper cam surface 66 and the lower cam surface 62 slide into contact with each other as the cylinder portion 10 rotates relative to each other, the ratchet cylinder portion 40 rises with respect to the lower cylinder portion 10. At this time, the protruding portion 71 of the urging portion 70 comes into contact with the stepped portion 22 of the nozzle cylinder 20 from below, and the urging portion 70 exerts a downward urging force on the ratchet cylinder portion 40.

Here, the upper ratchet claw 44 of the ratchet cylinder portion 40 and the lower ratchet claw 19 of the lower cylinder portion 10 are engaged with the ratchet teeth 53 of the ratchet shaft 50. The upper ratchet claw 44 regulates the downward relative movement of the ratchet shaft 50. Therefore, when the ratchet cylinder portion 40 rises with respect to the lower cylinder portion 10, the ratchet shaft 50 also rises. On the other hand, the lower ratchet claw 19 allows the relative movement of the ratchet shaft 50 upward. Therefore, the ratchet shaft 50 rises together with the ratchet cylinder portion 40 with respect to the lower cylinder portion 10 while causing the lower ratchet claw 19 to get over the ratchet teeth 53. At this time, the cam mechanism 60 raises the ratchet cylinder portion 40 with respect to the lower cylinder portion 10 by a distance corresponding to the pitch of the ratchet teeth 53. As a result, the ratchet shaft 50 rises with respect to the lower cylinder portion 10 by one tooth of the ratchet teeth 53.

When the rotation of the ratchet cylinder 40 with respect to the relay portion 12 progresses and the tips of the lower cam portion 61 and the upper cam portion 65 are in sliding contact with each other, the ratchet cylinder portion 40 reaches the ascending end position with respect to the relay portion 12. Then, after that, the lower cam portion 61 can approach the flange portion 42 of the ratchet cylinder portion 40, and the upper cam portion 65 can approach the upper end surface of the relay portion 12 of the lower cylinder portion 10. That is, the ratchet cylinder portion 40 provided with the upper cam portion 65 can be lowered with respect to the lower cylinder portion 10 provided with the lower cam portion 61. The ratchet cylinder portion 40 is urged downward with respect to the nozzle cylinder 20 by the urging portion 70. Since the nozzle cylinder 20 is provided so as not to be able to rise with respect to the lower cylinder portion 10, the ratchet cylinder portion 40 descends with respect to the nozzle cylinder 20. At this time, the lower ratchet claw 19 regulates the lowering of the ratchet shaft 50. On the other hand, the upper ratchet claw 44 allows the ratchet shaft 50 to rise with respect to the ratchet cylinder 40, that is, the ratchet shaft 40 to fall with respect to the ratchet shaft 50. Therefore, the ratchet cylinder portion 40 lowers the ratchet cylinder portion 40 by one tooth of the ratchet tooth 53 with respect to the lower cylinder portion 10 while causing the upper ratchet claw 44 to get over one ratchet tooth 53.

As described above, the content X supported by the ratchet shaft 50 can be raised by one tooth of the ratchet teeth 53 and fed out from the upper end opening 20a of the nozzle cylinder 20. By the way, when the ratchet shaft 50 is raised by the rotation operation of the nozzle cylinder 20, the urging force of the urging portion 70 acts on the cam mechanism 60 and is generated as a rotation resistance with respect to the nozzle cylinder 20. Therefore, each time the upper cam portion 65 gets over the lower cam portion 61 and the ratchet shaft 50 rises by one tooth of the ratchet teeth 53 by the rotation operation of the nozzle cylinder 20, the rotational resistance acting on the nozzle cylinder 20 increases or decreases. When the nozzle cylinder 20 is rotated to the second side R2 in the circumferential direction with respect to the lower cylinder portion 10, the upper regulation surface 67 of the upper cam portion 65 comes into contact with the lower regulation surface 63 of the lower cam portion 61, and further. The relative rotation of the ratchet cylinder portion 40 and the relay portion 12 of the above is restricted.

As described above, according to the present embodiment, the content X can be fed out from the nozzle cylinder 20 one by one of the ratchet teeth 53. Therefore, according to the feeding container 1, it is possible to suppress excessive feeding of the content X.

Further, the urging portion 70 is integrally formed with the ratchet cylinder portion 40. Therefore, since the ratchet cylinder portion 40 and the urging portion 70 can be made into a single member, the number of parts can be reduced as compared with the case where the ratchet cylinder portion and the urging portion are separately formed. In particular, in the present embodiment, since the urging portion 70 and the ratchet cylinder portion 40 are formed of a resin material, the component cost can be reduced as compared with the case where the urging portion is formed of a metal material.

Further, since the rotational resistance acting on the nozzle cylinder 20 increases or decreases each time the ratchet shaft 50 rises by one tooth of the ratchet tooth 53 due to the rotation operation of the nozzle cylinder 20, the content X is extended by one tooth of the ratchet tooth 53. It is possible to give a click feeling to the user who touches the lower cylinder portion 10 and the nozzle cylinder 20 each time. Therefore, it is possible to suppress the nozzle cylinder 20 from being rotated too much and to suppress the content X from being excessively ejected.

Further, when the nozzle cylinder 20 is rotated to the second side R2 in the circumferential direction with respect to the lower cylinder portion 10, when the upper cam portion 65 and the lower regulation surface 63 of the lower cam portion 61 come into contact with each other, the nozzle cylinder 20 is further rotated. Since the rotation of the nozzle cylinder 20 is restricted, the user can intuitively recognize the direction in which the nozzle cylinder 20 is rotated when the content X is fed out.

Further, the rotary ratchet mechanism 100 allows the rotation of the first side R1 in the circumferential direction of the ratchet cylinder portion 40 with respect to the nozzle cylinder 20 and regulates the rotation of the second side R2 in the circumferential direction. Therefore, when the ratchet cylinder portion 40 is rotated to the second side R2 in the circumferential direction with respect to the lower cylinder portion 10, a large force acts on the lower cam portion 61 and the upper cam portion 65, and the feeding container 1 is damaged. It can be suppressed.

The present invention is not limited to the above-described embodiment described with reference to the drawings, and various modifications can be considered within the technical scope thereof.
For example, in the above embodiment, the content X is formed so as to rise by rotating the nozzle cylinder 20 to the first side R1 in the circumferential direction with respect to the lower cylinder portion 10, but the present invention is not limited to this. That is, the contents may be formed so as to rise by rotating the nozzle cylinder to the second side R2 in the circumferential direction with respect to the lower cylinder portion.

Further, in the above embodiment, the relay portion 12 and the bearing portion 16 are integrally formed with the main body portion 11 in the lower cylinder portion 10, but the present invention is not limited to this. For example, the relay portion and the bearing portion may be integrally formed and may be provided separately from the main body portion. In this case, since the relay portion and the bearing portion can be assembled to the main body portion in a state where the ratchet shaft is assembled to the bearing portion, the main body portion may be formed in a bottomed cylindrical shape.

Further, in the above embodiment, both the lower cam portion 61 and the upper cam portion 65 constituting the cam mechanism 60 are provided with a cam surface. That is, both the lower cam portion 61 and the upper cam portion 65 function as a cam main body and also function as a follower 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.

Further, in the above embodiment, the ratchet shaft 50 supports the content X from below via the saucer 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 the contents may be directly supported from below.

Further, in the above embodiment, a pair of flattening portions 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 cylinder portion. For example, the flattening portion may be provided at only one location in the circumferential direction to form a D-cut surface, or the flattening portion may be provided at three or more locations in the circumferential direction.

Further, in the above embodiment, the distance at which the cam mechanism 60 raises the ratchet cylinder portion 40 with respect to the lower cylinder portion 10 matches the pitch of the ratchet teeth 53, but the present invention is not limited to this. The distance at which the cam mechanism 60 raises the ratchet cylinder portion 40 with respect to the lower cylinder portion 10 may be larger than the pitch of the ratchet teeth. As a result, by rotating the nozzle cylinder 20 with respect to the lower cylinder portion 10, the contents can be extended by at least one pitch of the ratchet teeth.

In addition, it is possible to replace the components in the above-described embodiment with well-known components as appropriate without departing from the spirit of the present invention.
