  According to the conventional delivery container, the delivery or withdrawal of the contents can be smoothly performed according to the rotation direction of the knob.

  However, depending on the user, it is also true that when the contents are fed out by rotating the knob, it may be desired that the feeding operation can be experienced. I can't respond.

  On the other hand, the inventor of the present application has found that the feeding of the contents can be experienced by adopting a ratchet mechanism for the rotating member.

  However, when the ratchet mechanism is adopted, the contents can be fed out, but a new problem has arisen that the withdrawal is impossible.

  The object of the present invention is to provide a novel device that allows the user to experience the feeding and withdrawal of the contents when the contents are fed and withdrawn without impairing the basic function of feeding or withdrawing the contents. It is to provide a feeding container.

The present invention has a cylindrical body for storing contents, an inner tray that holds the contents stored in the cylindrical body and can be moved up and down inside the cylindrical body, and a shaft portion that penetrates the inner tray. A feeding container provided with a rotating member that raises and lowers the inner plate by rotation of a knob provided at the lower end of the shaft part,
The shaft portion of the rotating member includes a claw portion that engages with a rack portion formed on the inner peripheral surface of the cylindrical body, and the claw portion gets over the rack portion so that the shaft portion rotates relative to the cylindrical body. A locking member that allows only one direction is provided,
The locking member has a holding surface that holds the shaft portion, and the holding surface includes a holding portion that can be deformed and restored in a direction that allows the rotation according to the rotation of the shaft portion. It is what.

  According to the present invention, the holding portion can be two beam portions that sandwich the shaft portion so as to be deformable and recoverable.

  According to the present invention, the knob part can be fitted to the inner peripheral surface on the lower end side of the cylindrical body so that the knob part is allowed to rotate.

  According to the present invention, when the rotating member is rotated via the knob in a direction in which the claw portion of the locking member can get over the rack portion of the cylindrical body, the click feeling is generated when the claw portion gets over the rack portion. Is obtained. Here, the click feeling means, for example, a feeling of getting over when the claw part gets over the rack part or a sound emitted when getting over.

  On the other hand, when the rotating member is rotated in the opposite direction via the knob, the claw portion is caught by the rack portion to prevent the rotation, but the holding portion that holds the shaft portion is deformed and restored. The reverse rotation of the shaft portion relative to the locking member is allowed while feeling the tightness obtained by deforming the holding portion and the feeling of return when restored after deformation. That is, by rotating the rotating member via the knob, the function itself of raising and lowering the inner tray according to the rotation direction is not impaired.

  Therefore, it is possible to experience the feeding and withdrawal of the contents when the contents are fed and withdrawn without impairing the basic function of feeding or withdrawing the contents.

  Further, if the holding portion is made of two beam portions that sandwich the shaft portion so that the shaft portion can be deformed and restored, the deformation and restoration around the shaft portion can be realized not only in material but also mechanically. Can be realized. Thereby, since the freedom degree can be given to the material used for a locking member, the expansion of an application range can be aimed at.

  Also, each of the beam portions is provided with a curved portion that forms a clamping surface for clamping the flat portion of the shaft portion, and if the portion where the curved portion begins to be curved is defined as a movable portion, the shaft portion is defined as the starting point of the movable portion. Deformation and restoration at the sandwiched portion are facilitated.

  Furthermore, if the knob is fitted to the inner peripheral surface on the lower end side of the cylindrical body so that the knob is allowed to rotate, the feeding and withdrawal of the contents according to the rotation of the knob can be stably performed. It can be realized with a feeling.

  Further, as shown in FIG. 2, the shaft portion 4a is rotatably held by a plurality of protrusions 1c that form an opening A formed in the bottom portion 1b. In addition, as shown in FIG. 2, a portion having a flat cross-sectional shape (hereinafter referred to as “flat portion”) R is formed on the shaft portion 4 a as shown in FIG. 4 at the connecting portion with the knob portion 4 b. ing.

  Reference numeral 5 denotes a locking member that gives a click feeling when the rotating member 4 is operated in accordance with the rotation direction. The locking member 5 has two claw portions 5a that engage with each of the plurality of teeth 2a constituting the rack portion 2 so as to be able to get over. As shown in FIG. 4 and the like, the two claw portions 5a are disposed at positions facing each other with the axis O interposed therebetween.

  Further, as shown in FIG. 4, the two claw portions 5a are inclined in the same direction around the axis O, and the plurality of teeth 2a constituting the rack portion 2 are also claw portions 5a in the same direction around the axis O. Inclined in the opposite direction. Thereby, when the two claw portions 5a get over the tooth 2a along the inclined surface of the tooth 2a, the locking member 5 is allowed to rotate, and when the side end face is caught on the side end face of the tooth 2a. The rotation of the locking member 5 is restricted.

  That is, the two claw portions 5a and the rack portion 2 allow only the rotation in the direction in which the inner plate 3 is raised by the two claw portions 5a getting over the plurality of teeth 2a constituting the rack portion 2, respectively.

  Between the two claw portions 5a, there is provided a holding portion C that has a holding surface 5f that holds the shaft portion 4a, and the holding surface 5f can be deformed and restored according to the rotation of the shaft portion 4a. Yes. In this embodiment, the holding part C is two beam parts 5b that can be deformed and restored with the holding surface 5f holding the flat part R provided in the shaft part 4a.

  As a result, if the rotating member 4 is rotated through the knob 4b in the direction in which the claw portions 5a of the locking member 5 get over the plurality of teeth 2a constituting the rack portion 2, as shown in FIG. Since the two beam portions 5b maintain the state in which the flat surface 4f of the flat portion R provided on the shaft portion 4a is sandwiched, the rotating member 4 and the locking member 5 rotate integrally.

  Therefore, if the rotating member 4 is rotated via the knob 4b in a direction in which the claw portions 5a of the locking member 5 respectively cross the plurality of teeth 2a constituting the rack portion 2, the inner plate 3 with a click feeling is obtained. Can be raised.
