  However, in the conventional feeding container, there is room for improvement in suppressing the inner cylinder part of the container main body and the outer casing from rattling in the container axial direction, for example, during operation.

  This invention is made | formed in view of the situation mentioned above, The objective is providing the delivery container which can suppress that the inner cylinder part and exterior body of a container main body rattle in the container axial direction. is there.

In order to solve the above problems, the present invention proposes the following means.
The feeding container according to the present invention includes a container body having an inner cylinder part, and an outer cylinder part that is externally rotatably mounted on the inner cylinder part in a circumferential direction, and is advanced and retracted in the container axial direction within the inner cylinder part. A holding portion that holds the contents contained in the container body, and holds the contents in a state of protruding the contents to one side in the container axial direction. As the inner cylinder part and the outer cylinder part are rotated relative to each other in the circumferential direction, the container is moved forward and backward in the axial direction of the container. Projecting from the opening, the outer cylinder part is displaced on the one side of the inner cylinder part and is externally mounted, and the inner cylinder part is positioned on the other side in the container axial direction than the outer cylinder part. The bottomed cylindrical outer casing is restricted from rotating in the circumferential direction with respect to the inner cylindrical portion. A feeding container externally packaged, wherein a hole opening in the opening on the other side of the inner cylinder portion is provided in the bottom wall portion of the outer casing in the container axial direction, and the bottom wall An elastic engagement portion that engages with an engaged portion provided on an inner peripheral surface of the inner cylinder portion is connected to a peripheral edge portion of the hole portion in the portion, and the elastic engagement portion extends in a container axial direction. It is engaged with the engaged part from the one side in an elastically deformed state, and the inner cylinder part is urged to the other side by an elastic restoring force so as to be in pressure contact with the exterior body. To do.

According to this invention, the elastic engagement portion is engaged with the engaged portion of the inner cylinder portion from the one side while being elastically deformed in the container axial direction, and the inner cylinder portion is moved to the other side by elastic restoring force. Since the outer body is urged to the outer body and pressed against the outer body, the movement of the inner cylindrical portion of the container body relative to the outer body in the container axial direction can be restricted from both sides in the container axial direction by the elastic engagement portion and the outer body. It becomes possible, and it can suppress effectively that the inner cylinder part and exterior body of a container main body rattle in the container axial direction.
In addition, in this way, the inner cylinder portion is biased to the other side by the elastic restoring force of the elastic engagement portion, so that rattling is suppressed, so that the dimensions of the inner cylinder portion and the exterior body vary within manufacturing tolerances. Even if it does, rattling can be suppressed reliably.

  In addition, the elastic engaging portion is connected to a pair of connecting portions separately connected to a circumferentially spaced portion in the peripheral portion of the hole portion, and both the connecting portions are connected to contact the engaged portion. And a main body part.

  In this case, since the elastic engagement portion includes the pair of connection portions and the main body portion, the force received by the main body portion from the engaged portion of the inner cylinder portion is distributed and received by the pair of connection portions. The inner cylinder part is reliably urged to the other side by the elastic restoring force of the elastic engagement part, and it is more effective that the inner cylinder part of the container body and the exterior body rattle in the container axial direction. Can be suppressed.

  A pair of the elastic engagement portions may be arranged with the container shaft interposed therebetween.

It becomes possible to act, and it can suppress more effectively that the inner cylinder part and exterior body of a container main body rattle in the container axial direction.
In addition, since a pair of elastic engagement portions are arranged with the container shaft in between, when the elastic engagement portion is engaged with the engaged portion, both elastic engagement portions are elastically deformed in a direction approaching each other. Then, after moving the main body portion of the elastic engagement portion from the other side to the one side with respect to the engaged portion, the elastic engagement portion is restored and deformed in a direction away from each other. It becomes possible to get the engaged portion over the main body portion of the joint portion in the container axial direction, and the assembly work of the feeding container can be simplified.

  The hole may be covered from the other side with a covering member fixed to the bottom wall of the exterior body.

  In this case, since the hole is covered from the other side by the covering member, foreign matters such as dust can be prevented from entering the inner cylinder through the hole.

  Further, the outer cylinder part is urged toward the one side with respect to the inner cylinder part, and the urging part provided in the outer cylinder part is pressed against the receiving part provided in the inner cylinder part. A member may be provided.

In this case, since the urging member is provided, it becomes possible to restrict the movement of the outer cylinder part in the container axial direction relative to the inner cylinder part from both sides in the container axial direction by the urging member and the receiving part, It is possible to effectively prevent the inner cylinder part and the outer cylinder part from rattling in the container axial direction.
In addition, since the rattling is suppressed by urging the outer cylinder portion with respect to the inner cylinder portion by the urging member in this way, it is assumed that the dimensions of the inner cylinder portion and the outer cylinder portion vary within the manufacturing tolerance. However, rattling can be reliably suppressed.

  Further, the urging member may be formed in an annular shape extending in the circumferential direction while alternately bending in the container axial direction.

  In this case, since the urging member is formed in an annular shape extending in the circumferential direction while being alternately bent in the container axial direction, the structure of the feeding container can be simplified.

  Further, a protruding portion that protrudes outward in the radial direction is formed in a portion of the inner cylindrical portion that is located on the other side of the outer cylindrical portion, and the urging member includes the protruding portion and the outer cylindrical portion. Between them.

  In this case, since the urging member is disposed between the projecting portion of the inner cylinder portion and the outer cylinder portion, for example, the urging member includes a member different from the inner cylinder portion, and the outer cylinder portion. Compared with the case where it is arranged between, the urging member positively urges the outer cylinder part to the one side with respect to the inner cylinder part, and the abutting part of the outer cylinder part is received by the inner cylinder part. It is possible to strongly press the part, and it is possible to more effectively suppress the inner cylinder part and the outer cylinder part from rattling in the container axial direction.

  When the urging member is formed in an annular shape extending in the circumferential direction while alternately curving in the container axial direction, the portion of the urging member that protrudes toward the one side is the outer cylinder. It is possible to abut the portion projecting toward the other side and projecting toward the other side to the projecting portion of the inner cylinder portion, and the urging member can be applied to either the inner cylinder portion or the outer cylinder portion. It can be made to contact intermittently at intervals in the circumferential direction. Thereby, for example, compared with the case where the urging member is continuously in contact with both the inner cylinder part and the outer cylinder part over the entire circumference in the circumferential direction, between the urging member and the inner cylinder part, Further, it is possible to reduce the frictional force generated between the urging member and the outer cylinder part, and to ensure the operability by smoothly rotating the inner cylinder part and the outer cylinder part relatively in the circumferential direction. Can do.

  In addition, the biasing member may be provided with a plurality of pressure contact members that are in pressure contact with the inner cylinder portion from the inside or the outside in the radial direction, or may be provided over the entire circumference in the circumferential direction.

In this case, since the pressing member is provided on the urging member, the inner cylinder portion and the outer cylinder portion are not intended in the circumferential direction while preventing the outer cylinder portion and the inner cylinder portion from rattling in the radial direction. It is possible to prevent the inner cylinder part and the outer cylinder part from rattling in the container axis direction more effectively.
In addition, when the press-contact member is formed integrally with the urging member, it is possible to suppress an increase in the number of parts, and it is also possible to suppress the complexity of the structure.

  The hole 30 is covered from the rear side with a covering member 32 fixed to the bottom wall portion of the exterior body 28. An annular leg portion 28b projecting rearward is disposed on the outer peripheral edge of the bottom wall portion of the exterior body 28, and the covering member 32 is fixed to the inside of the leg portion 28b in the bottom wall portion. . The covering member 32 is formed in a sheet shape whose size along the container axis O direction is smaller than that of the leg portion 28b, and closes the hole 30 from the rear.

When the delivery container 10 is used, after the overcap 33 is detached from the exterior body 28, the exterior body 28 and the outer cylinder portion 12 of the container body 13 are separately held, and the exterior body 28 and the outer cylinder portion are separated. 12 is relatively rotated in the circumferential direction, and the inner cylinder portion 11 and the outer cylinder portion 12 are relatively rotated in the circumferential direction. At this time, the outer cylinder portion 12 is rotated relatively to one side in the circumferential direction with respect to the inner cylinder portion 11, and the mounting protrusion 25 is moved to the front side along both the inner hole 23 and the outer hole 24. The holding part 14 is advanced, and the contents A are projected forward from the opening on the front side of the container body 13.
After the contents A are used, the exterior body 28 and the outer cylindrical portion 12 are rotated relatively opposite to each other in the circumferential direction, and the mounting projection 25 is moved to the rear side along both the inner hole 23 and the outer hole 24. Move to. Then, the holding part 14 is retracted, and the content A is immersed backward from the opening on the front side of the container body 13. In this way, the holding part 14 moves the inside of the inner cylinder part 11 back and forth in the direction of the container axis O, so that the content A appears and disappears with respect to the opening on the front side of the container body 13.

As described above, according to the feeding container 10 according to the present embodiment, the elastic engagement portion 31 is elastically deformed in the container axis O direction from the front side to the engaged portion 17 of the inner cylinder portion 11. Since the inner cylinder portion 11 is urged rearward by the elastic restoring force to be brought into pressure contact with the exterior body 28, the movement of the inner cylinder portion 11 of the container body 13 relative to the exterior body 28 in the container axis O direction is performed. The elastic engagement part 31 and the outer body 28 can be regulated from both sides in the container axis O direction, and it is effective that the inner cylinder part 11 of the container body 13 and the outer body 28 rattle in the container axis O direction. Can be suppressed.
Further, in this way, rattling is suppressed by urging the inner cylinder portion 11 to the rear side by the elastic restoring force of the elastic engagement portion 31, and therefore, the dimensions of the inner cylinder portion 11 and the exterior body 28 are temporarily subject to manufacturing tolerances. Even if it fluctuates within, it is possible to reliably suppress rattling.

  Further, since the elastic engagement portion 31 includes the pair of connection portions 31a and the main body portion 31b, the force received by the main body portion 31b from the engaged portion 17 of the inner cylinder portion 11 is applied to the pair of connection portions 31a. The inner cylindrical portion 11 is reliably urged to the rear side by the elastic restoring force of the elastic engaging portion 31 so that the inner cylindrical portion 11 and the outer body 28 of the container main body 13 are connected to the container. Shaking in the direction of the axis O can be more effectively suppressed.

Further, since the elastic engagement portions 31 are disposed in a pair with the container shaft O interposed therebetween, the elastic restoring force of the elastic engagement portion 31 is formed in a portion of the inner cylinder portion 11 positioned with the container shaft O interposed therebetween. Can be made to act separately, and rattling of the inner cylinder portion 11 and the exterior body 28 of the container main body 13 in the container axis O direction can be further effectively suppressed.
Further, since the elastic engagement portions 31 are arranged in a pair with the container shaft O interposed therebetween, when the elastic engagement portions 31 are engaged with the engaged portions 17, the elastic engagement portions 31 are brought close to each other. The main body portion 31b of the elastic engagement portion 31 is moved from the rear side to the front side with respect to the engaged portion 17 while being elastically deformed in the direction to be moved, and then both elastic engagement portions 31 are restored and deformed in a direction away from each other. By doing so, the engaged portion 17 can be moved over the main body portion 31b of the elastic engagement portion 31 in the direction of the container axis O, and the assembling work of the feeding container 10 can be simplified.

  Further, since the hole 30 is covered from the rear side by the covering member 32, it is possible to prevent foreign matters such as dust from entering the inner cylinder portion 11 through the hole 30.

Further, since the urging member 27 is provided, the movement of the outer cylinder portion 12 in the container axis O direction relative to the inner cylinder portion 11 is restricted from both sides in the container axis O direction by the urging member 27 and the receiving portion 18. It becomes possible, and it can suppress effectively that the inner cylinder part 11 and the outer cylinder part 12 rattle in the container axis O direction.
Further, since the rattling is suppressed by urging the outer cylinder portion 12 with respect to the inner cylinder portion 11 by the urging member 27 in this manner, the dimensions of the inner cylinder portion 11 and the outer cylinder portion 12 are temporarily subject to manufacturing tolerances. Even if it fluctuates within, it is possible to reliably suppress rattling.
