Dispenser and cartridge for dispenser

Abstract

To provide a delivery container capable of replacing a used cartridge with a new cartridge, and a cartridge for the delivery container.SOLUTION: A delivery container 1 comprises a base 2 with a rotating body 5, and a cartridge 7 mounted on the base 2 and when the rotating body 5 is rotated, delivering a rod-like content, where the base 2 includes a shaft body 6 rotating together with the rotating body 5, being movable forward and backward relative to the rotating body, and having a first engaging part and a first screwing part, and a base body 3 having a mounting opening 3e and a first lock part. The cartridge 7 includes an inner tray 9 for holding the rod-like content and having a second engaging part, and a cartridge body 8 having a second screwing part and a second lock part engaging with the first lock part. The first engaging part and the second engaging part removably engage with each other, and the first screwing part and the second screwing part removably screw with each other. When the rotating body 5 is rotated, the inner tray 9 moves forward and backward together with the shaft body 6.SELECTED DRAWING: Figure 1

Claims

1. A dispensing container comprising a base equipped with a rotating body, and a cartridge mounted on the base from which a rod-shaped contents are dispensed when the rotating body is rotated, The aforementioned base is A shaft body that rotates together with the rotating body and is movable forward and backward relative to the rotating body, having a first engaging portion and a first screwed portion, The rotating body comprises a base body that rotatably supports the rotating body, having a mounting opening centered on the central axis of the rotating body and a first locking portion that protrudes radially inward from the mounting opening, The aforementioned cartridge is A middle tray that holds the rod-shaped contents and has a second engaging portion, The cartridge body comprises a second screw portion and a second lock portion that engages with the first lock portion when inserted into the mounting opening and rotated around the central axis, and surrounds the rod-shaped contents and the inner tray and is mounted on the base body. The first engaging portion and the second engaging portion are detachably engaged, and the first threaded portion and the second threaded portion are detachably screwed together. The cartridge body is held in place on the base body by the engagement of the first locking portion and the second locking portion, and the first engaging portion and the second engaging portion are configured to be disengaged and the first threaded portion and the second threaded portion are threaded together. As the rotating body rotates, the shaft advances relative to the rotating body, causing the first engaging portion and the second engaging portion to engage, and the middle tray moves back and forth together with the shaft in this dispensing container.

2. The dispensing container according to claim 1, wherein either the base body or the cartridge body has an engaging projection, and the other of the base body or the cartridge body has an engaging recess that engages with the engaging projection when the first locking portion and the second locking portion are engaged.

3. The dispensing container according to claim 1, wherein the cartridge body has a rotation stopper that contacts the first locking portion when the second locking portion is inserted into the mounting opening and rotated around the central axis, thereby stopping the rotation of the cartridge body relative to the base body.

4. The dispensing container according to claim 1, wherein the shaft has a retaining portion that prevents the shaft from coming out of the rotating body.

5. The cartridge body has an engagement portion on the inner tray side and an engagement portion on the cartridge body side that engage with each other when the inner tray is retracted relative to the cartridge body, The dispensing container according to claim 1, wherein the interlocking portion on the inner tray side is connected to a weakening portion provided on the inner tray and is configured to elastically deform when the weakening portion breaks, and / or the interlocking portion on the cartridge body side is connected to a weakening portion provided on the cartridge body and is configured to elastically deform when the weakening portion breaks.

6. The first engaging portion comprises a cylindrical portion extending along the central axis of the rotating body and a first projection protruding from the inner circumferential surface of the cylindrical portion. The second engaging portion comprises a shaft-shaped portion that extends along the central axis of the rotating body and is inserted into the cylindrical portion, and a second projection that protrudes from the outer circumferential surface of the shaft-shaped portion and engages with the first projection. Furthermore, the dispensing container according to claim 1 is further provided with a slit that cuts out the cylindrical portion to cause elastic deformation of the cylindrical portion, and / or a slit that cuts out the shaft portion to cause elastic deformation of the shaft portion.

7. A cartridge for a dispensing container, which is mounted on a base equipped with a rotating body, and in which a rod-shaped contents are dispensed when the rotating body is rotated, The aforementioned base is A shaft body that rotates together with the rotating body and is movable forward and backward relative to the rotating body, having a first engaging portion and a first screwed portion, The system is configured to include a base body that rotatably supports the rotating body, having a mounting opening centered on the central axis of the rotating body and a first locking portion that protrudes radially inward from the mounting opening, A middle tray that holds the rod-shaped contents and has a second engaging portion, The cartridge body comprises a second screw portion and a second lock portion that engages with the first lock portion when inserted into the mounting opening and rotated around the central axis, and surrounds the rod-shaped contents and the inner tray and is mounted on the base body. The first engaging portion and the second engaging portion are detachably engaged, and the first threaded portion and the second threaded portion are detachably screwed together. The cartridge body is held in place on the base body by the engagement of the first locking portion and the second locking portion, and the first engaging portion and the second engaging portion are configured to be disengaged and the first threaded portion and the second threaded portion are threaded together. A cartridge for a dispensing container in which, as the rotating body rotates, the shaft advances relative to the rotating body, causing the first engaging portion and the second engaging portion to engage, and the middle tray moves back and forth together with the shaft.
