  However, in the conventional container with an applicator, when the contents in the container body are reduced, the applicator may not be in sufficient contact with the contents, for example, with the cap body attached to the container body. However, there was a risk that it would be difficult to hold the contents.

  The present invention has been made in view of the above-described circumstances, and the object thereof is to make it easier to hold the contents in the application portion even when the contents in the container body are reduced, and to reduce the remaining amount. It is providing the container with an applicator which can do.

In order to solve the above problems, the present invention proposes the following means.
A container with an applicator according to the present invention includes a bottomed cylindrical container main body in which contents are stored, a cap body that is detachably attached to the mouth of the container main body, and a cap body that is attached to the cap body. An applicator with an applicator projecting from the cap body toward the bottom side of the container body and having an applicator disposed at the tip, wherein the cap body is mounted with the applicator A base cylinder part, and a rotation cylinder part that is extrapolated to the base cylinder part so as to be rotatable around a container axis, and moves the applicator forward and backward in the container axis direction in accordance with the rotation with respect to the base cylinder part, The applicator has an inner hole formed in the base tube portion that penetrates in the radial direction and a mounting protrusion that is integrally inserted into an outer hole that opens toward the inner side in the radial direction formed in the rotary tube portion. One of the inner hole and the outer hole is provided. It extends so as to form a spiral in the circumferential direction along the axis, the other extends in the container axial direction, and when the applicator is positioned at the forward end position, the applicator is attached to the cap body, A biasing member that biases toward the opposite bottom side opposite to the bottom side, and is inserted into or inserted into the mouth part and connected to the base cylinder part, and is around the container axis with respect to the mouth part And a mounting cylinder part that is attached to and detached from the mouth part by being rotated to the mouth part, and the mounting cylinder part rotates with respect to the base cylinder part when the applicator is advanced in a circumferential direction. When the tube is rotated with respect to the mouth toward the one side, the tube is separated from the mouth, and when the applicator is positioned at the forward end position in the base tube, The engaging part formed on the rotating cylinder part engages from the other side opposite to the one side, so that the front Wherein the rotation restricting portion is formed to restrict the further rotation toward the one side of the rotary cylinder unit relative to the base tube part.
The applicator is attached to the base tube portion, and extends downward from the base portion, and is inserted into a seal member disposed in the base tube portion, and is applied to the lower end of the applicator. A rod portion provided with a portion, and when the outer diameter of the lower portion of the rod portion is larger than the outer diameter of the upper portion and the applicator is located at the retracted end position, the rod portion The step portion connecting the upper portion and the lower portion may be in contact with the lower end of the seal member.

In the present invention, when the contents are applied, with the cap body attached to the container body, the rotating cylinder part is rotated to one side in the circumferential direction with respect to the base cylinder part, and the attachment protrusions are formed in the inner hole and the outer hole. By moving the applicator to the bottom side along both directions, the applicator is advanced to the forward end position against the urging force of the urging member, and the amount of protrusion of the applicator from the cap body is increased. Thereafter, the cap body is detached from the container body, and the contents held in the application part are applied to the application part.
After the contents have been applied, the cap body is attached to the container body, and the rotating cylinder portion is rotated to the other side opposite to the one side with respect to the base cylinder portion, so that the attachment protrusion is formed in the inner hole. The applicator is retracted from the forward end position by moving toward the opposite bottom side along both the outer hole and the projecting amount of the applicator from the cap body.

After the cap body 14 is detached from the mouth portion 12 of the container body 11 as described above, the contents held in the application portion 16 are applied to the application portion.

  When the application of the contents is finished and the cap body 14 is attached to the container main body 11, the applicator 17 attached to the cap body 14 is caused to enter the mouth portion 12 from the tip as shown in FIG. Thereafter, the cap body 14 and the container body 11 are moved relatively close to each other in the container axis O direction while aligning the cap body 14 and the container body 11 in the radial direction and the circumferential direction. 34 is passed between the concave portion defining portions 22 adjacent to each other in the circumferential direction in the mouth portion 12.

  Thereafter, the rotating cylinder portion 32 is rotated to the other side. At this time, when the rotating tube portion 32 and the mounting tube portion 13 rotate together on the other side, the claw portion 34 of the mounting tube portion 13 gets over the third protrusion 25 of the recess defining portion 22 and is disposed in the recessed portion. The mounting cylinder portion 13 is mounted in the mouth portion 12.

  At this time, for example, the claw portion 34 of the mounting cylinder portion 13 comes into contact with the third ridge portion 25 or the first ridge portion 23 of the concave portion defining portion 22, so that the mouth portion of the mounting cylinder portion 13 is made. Accordingly, the rotation cylinder portion 32 is rotated to the other side with respect to the base cylinder portion 31. At this time, as shown in FIG. 3, the mounting projection 44 moves upward along both the inner hole 38 and the outer hole 40, so that the applicator 17 tends to retreat in the container axis O direction.

  Then, first, the mounting protrusion 44 gets over the protrusion restricting portion 54 and the engagement of the protrusion restricting portion 54 with the mounting protrusion 44 is released. Thereafter, the mounting protrusion 44 moves upward along both the inner hole 38 and the outer hole 40, gets over the position holding portion 53, is positioned at the upper peripheral end portion 38 a of the inner hole 38, and defines the inner hole 38. Among the wall surfaces to be formed, it contacts or approaches the wall surface facing the one side. Thereby, the applicator 17 is retracted from the forward end position to the retracted end position, and the protruding amount of the applicator 17 from the cap body 14 is restored.

  Here, since the applicator 17 is urged upward by the urging member 52 when the applicator 17 is located at the forward end position, the mounting projection 44 is directed upward along both the inner hole 38 and the outer hole 40. Move smoothly. In the present embodiment, the applicator 17 is urged by the urging member 52 over the entire length from the forward end position to the backward end position.

  When the container with applicator 10 is not used, the position holding portion 53 is locked to the mounting protrusion 44 as shown in FIG. 3, so that the mounting protrusion 44 extends along both the inner hole 38 and the outer hole 40. The downward movement is restricted. Therefore, it is possible to suppress the applicator 17 from moving forward when the rotating cylinder portion 32 is rotated slightly unintentionally with respect to the base cylinder portion 31, and the position of the applicator 17 in the container axis O direction can be stabilized. .

As described above, according to the container 10 with the applicator according to the present embodiment, before the cap body 14 is detached from the container body 11, the amount of protrusion of the applicator 17 from the cap body 14 is increased, and the applicator 16 Can be brought close to, in contact with or pressed against the bottom 15 of the container body 11.
Therefore, even when the applicator 16 does not sufficiently contact the contents in the container body 11 when the contents in the container body 11 are reduced, for example, when the applicator 17 is located at the retracted end position. The application unit 16 can be re-entered into the contents. Moreover, when the contact amount (area) with the contents of the application part 16 becomes small, the contact amount can be increased. Furthermore, when the contents remain slightly on the bottom 15 in the container main body 11, the application part 16 can be brought into contact with or pressed against the bottom 15 to hold the contents in the application part 16. .
By the above, even if the content in the container main body 11 decreases, the content can be easily held in the application unit 16 and the remaining amount can be reduced.

  Further, when the contents are applied using the container 10 with the applicator, the amount of protrusion of the applicator 17 from the cap body 14 can be increased and then returned to the original state. When not used, the application unit 16 can be separated from the bottom 15 of the container main body 11, and the application unit 16 can be brought into contact with or pressed against the bottom 15 of the container main body 11 when used. Thus, by keeping the application part 16 away from the bottom 15 of the container body 11 when not in use, it is possible to suppress the load from being applied to the application part 16 from the bottom 15 of the container body 11. The durability of 16 can be easily secured.

  Further, since the applicator 17 is biased upward by the biasing member 52 when positioned at the forward end position, the mounting projection 44 moves upward along both the inner hole 38 and the outer hole 40. Can be smoothly performed, and the applicator 17 can be smoothly retracted with a small force.

Furthermore, when applying the contents, not only the applicator 17 is advanced to the forward end position by simply rotating the rotary cylinder 32 toward the one side, but also the cap body 14 is moved to the mouth of the container body 11. Therefore, the operability of the applicator-equipped container 10 can be improved.
In addition, in the present embodiment, the rotational force applied to the one side on the rotating cylinder portion 32 is transmitted through the pressing wall surface 50 c, the mounting protrusion 44, the regulating wall surface 50 b, and the base cylinder portion 31. Therefore, the operability of the container with applicator 10 can be improved and the structure of the container 10 with applicator can be prevented from becoming complicated as described above.

  Further, since the protrusion regulating portion 54 is formed on the guide wall surface 50a of the inner hole 38, the applicator 17 is urged upward by the urging member 52 when the applicator 17 is located at the forward end position. Only, the locking of the projection restricting portion 54 with respect to the mounting projection 44 is not released, and in addition to the urging by the urging member 52, the rotating cylinder portion 32 is rotated to the other side with respect to the base cylinder portion 31. The projection restricting portion 54 can be unlocked from the mounting projection 44. Thereby, when the rotating cylinder part 32 is not rotated with respect to the base cylinder part 31, rotating the rotating cylinder part 32 with respect to the base cylinder part 31 is suppressed, preventing the applicator 17 from retreating unexpectedly. When this is done, the applicator 17 can be reliably retracted.
