  However, in the conventional feeding container, there is room for improvement in improving the sealing performance between the inner plate, the container body, and the male screw shaft.

  This invention is made | formed in view of the above-mentioned subject, and it aims at providing the feeding container which improved the sealing performance between an inner tray, a container main body, and a male screw shaft.

The present invention employs the following means in order to solve the above problems. That is, the feeding container of the present invention is a container main body in which the contents are stored, a discharge member in which a discharge hole for discharging the contents is formed, and extends in the container main body along the container axial direction. And a male screw shaft rotatably disposed around the container shaft, and is slidably fitted in the container body and screwed to the male screw shaft, and the male screw shaft is rotated. And an inner tray that moves along the container axis in the container body, wherein the inner dish is screwed onto the male screw shaft, and the container body. A sliding cylinder portion having a sliding portion that slides on the inner peripheral surface of the internal thread portion, and an inner diameter of a part of the thread in the female screw portion is smaller than an inner diameter of the other portion, or An inner diameter of a part of the thread valley in the female screw part is smaller than an inner diameter of the other part, and the female screw part The part of the screw thread or the screw valley and the sliding part are formed of an elastically deformable material, and the outer side in the radial direction including the sliding part of the sliding cylinder part. The part is formed of the elastically deformable material from the radially inner part of the sliding cylinder part which is inside the radial outer part of the sliding cylinder part over the entire length along the container axis of the sliding cylinder part. It is characterized by being.

In this case, since a part of the screw thread or the screw valley in the female screw portion of the inner plate is in close contact with the male screw shaft, the content located in the discharge hole side along the container shaft from the inner plate in the container body. An object can be prevented from leaking to the side away from the discharge hole along the container shaft through the space between the male screw shaft and the female screw portion of the inner plate. Moreover, since the said part formed with the material which can be elastically deformed can be press-contacted to an external threaded shaft, the sealing performance between an external threaded shaft and an intermediate plate can be ensured reliably. On the other hand, since only a part of the screw thread or screw valley is in close contact with the male screw shaft, the rotational torque of the male screw shaft required to slide the inner pan along the container axis direction within the container body Can be prevented from becoming excessively high.
Further, since the sliding portion formed of an elastically deformable material can be brought into pressure contact with the inner peripheral surface of the container main body, the content located in the container main body on the discharge hole side along the container axial direction with respect to the middle dish An object can be prevented from leaking through between the inner peripheral surface of the container body and the sliding portion of the inner tray. Further, since the internal thread portion of the inner plate is pressed against the male screw shaft by the reaction force of the sliding portion being pressed against the inner peripheral surface of the container body, the thread or screw in the internal thread portion of the intermediate plate is pressed. The close contact between the part of the valley and the male screw shaft is further improved.
Thus, the sealing performance between the male screw shaft and the container main body and the inner tray can be improved.
For example, when the container body is a true cylinder, the frictional resistance of the sliding part against the inner peripheral surface of the container main body increases when the sliding part is pressed against the inner peripheral surface of the container main body. It is possible to prevent the inner plate from rotating with respect to the container body together with the male screw shaft as the screw shaft rotates.

In the present invention, the part of the screw thread or the screw valley in the female screw part and the sliding part may be integrally formed of the same material.
In this case, the part of the thread or the thread valley and the sliding part are integrally formed of the same material, so that the part of the thread or the thread valley in the female thread part of the intermediate plate slides. Can be formed easily and accurately.

In the present invention, the sliding cylinder part is provided with a pair of sliding parts at intervals along the container axis, and a pair of the sliding cylinder parts along the container axis. Between the sliding portions, a peripheral rib portion that is formed of an elastically deformable material and slides on the inner peripheral surface of the container main body may be formed.
In this case, the sealing performance between the male screw shaft and the container main body and the inner pan is improved as compared with the case where the outer peripheral surface of the sliding cylinder portion is in sliding contact with the inner peripheral surface of the container main body over the entire length in the container axial direction. Thus, it is possible to suppress the male screw shaft from becoming difficult to move in the container axis direction (the male screw shaft is difficult to rotate).
Furthermore, in this invention, the upper ends of the said internal thread part and the said sliding cylinder part may be connected.

  According to the feeding container of the present invention, the part formed of the elastically deformable material is pressed against the male screw shaft, and the sliding portion formed of the elastically deformable material is provided on the inner peripheral surface of the container body. Since it is press-contacted, the sealing performance between the male screw shaft and the inner surface of the container main body and the inner pan can be ensured. Further, for example, when the container body has a true cylindrical shape, the frictional resistance of the sliding portion with respect to the inner peripheral surface of the container body increases, so that the inner plate moves together with the male screw shaft along with the rotation of the male screw shaft. It can prevent rotating with respect to the main body.

  The male screw shaft 5 extends in the vertical direction in the container body 2 and is disposed so as to be rotatable around the container shaft O. The outer diameter of the upper end portion 41 is larger than the outer diameter of other portions. The diameter is expanded. An accommodation recess 41 </ b> A for accommodating the columnar portion 33 is formed at the center of the upper end portion 41, and a longitudinal rib meshing with a longitudinal rib portion formed on the inner cylinder portion 32 on the outer peripheral surface of the upper end portion 41. The portion protrudes radially outward in the vertical direction. Accordingly, the male screw shaft 5 rotates around the container axis O together with the operation member 4 as the operation member 4 rotates around the container axis O.

  In addition, a male screw portion 42 is formed substantially vertically in a portion of the outer peripheral surface of the male screw shaft 5 below the upper end portion 41. Further, the lower end portion of the male screw shaft 5 is inserted into the insertion tube portion 13 as shown in FIGS.

By inserting, the rotation of the male screw shaft 5 around the container axis O is stabilized.

  The inner tray 6 is formed integrally with the main body 6A and the main body 6A, and is formed of an elastically deformable material that is softer than the main body 6A, such as nitrile rubber, butyl rubber, silicon rubber, or elastomer. 6B. The elastic material portion 6B is disposed above the main body portion 6A. Further, the inner plate 6 includes a cylindrical female screw cylinder portion 51 screwed onto the male screw shaft 5, and a cylindrical sliding cylinder portion 52 disposed radially outside the female screw cylinder portion 51.

The female screw cylinder part 51, the sliding cylinder part 52, and the connecting cylinder part 53 are arranged with their respective central axes positioned on the container axis O.

  On the inner peripheral surface of the female screw cylinder portion 51, a female screw portion 54 that is screwed with the male screw portion 42 of the male screw shaft 5 is formed in the vertical direction. Here, the inner diameter of a part 54B (for example, 1 mm or more and 2 mm or less from the beginning of threading) of the thread 54A of the female thread portion 54 is larger than the inner diameter of a part other than the part 54B of the thread 54A. Is also getting smaller. Further, the part 54B is formed of a material that can be elastically deformed over the entire length in the vertical direction when viewed in the vertical cross-sectional view, and the peripheral surface of the part 54B is in direct contact with the male screw portion 42. Further, the part 54B is in pressure contact with the male screw portion 42.

The sliding cylinder portion 52 has a radially outer portion formed of an elastic material portion 6B, and a radially inner portion of this portion is formed of a main body portion 6A. Sliding portions 52A are formed at both upper and lower end portions of the sliding tube portion 52 so as to protrude outward in the radial direction from the center portion of the sliding tube portion 52 in the vertical direction. Is in sliding contact with the inner peripheral surface of the container body 2. Here, the sliding part 52A is formed of the elastic material part 6B, and is formed of the same material as the part 54B of the thread 54A.
The connecting cylinder part 53 has an outer diameter smaller than the inner diameter of the second outer cylinder part 36 of the operation member 4 and an inner diameter larger than the outer diameter of the inner cylinder part 32, and the inner tray 6 is a container body. 2 is positioned between the second outer cylinder part 36 and the inner cylinder part 32 of the operating member 4 as it moves upward (see the phantom line in FIG. 2).

  As shown in FIG. 2, the overcap 7 includes a disc-shaped top wall portion 61 and a cylindrical side wall portion 62 extending downward from the outer peripheral edge of the top wall portion 61 in a plan view. Have. The lower end portion of the side wall portion 62 is covered on the outer peripheral surface of the outer peripheral surface of the upper stage portion 12 of the container body 2 and the outer peripheral surface of the first outer cylinder portion 35 of the operation member 4, and covers the application member 25.

Next, a method of using the feeding container 1 having the above configuration will be described.
First, the overcap 7 is removed, and the outer cylinder portion 31 of the operation member 4 is exposed. When the outer cylinder portion 31 is rotated in one direction around the container axis O in this state, the male screw shaft 5 rotates around the container axis O as the operation member 4 rotates. Then, the inner tray 6 moves upward in the container body 2 as the male screw shaft 5 rotates relative to the inner tray 6.

  Here, the sliding portion 52 </ b> A formed in the elastic material portion 6 </ b> B is in pressure contact with the inner peripheral surface of the container body 2 in a state of being elastically deformed. Therefore, the frictional resistance between the inner tray 6 and the container body 2 increases, and the inner tray 6 moves stably upward without rotating together with the male screw shaft 5. Further, the sliding portion 52 </ b> A is in sliding contact with the inner peripheral surface of the container body 2, so that the sealing performance between the inner tray 6 and the container body 2 is improved.

  Further, the part 54B of the thread 54A is formed in the elastic material part 6B in the same manner as the sliding part 52A, and the inner diameter of the part 54B is that of the part other than the part 54B of the thread 54A. The peripheral surface of the part 54B is in direct contact with the male screw portion 42, being smaller than the inner diameter. Therefore, the part 54B is in close contact with the male screw shaft 5, and the sealing performance between the intermediate plate 6 and the male screw shaft 5 is improved. On the other hand, the rotational torque of the male screw shaft 5 does not become excessively high because only the part 54B of the thread 54A is pressed against the male screw portion 42. Here, since the sliding portion 52 </ b> A of the inner tray 6 is pressed against the inner peripheral surface of the container main body 2, the female screw portion 54 is directed radially inward toward the male screw shaft 5 due to the reaction from the container main body 2. Thus, the adhesiveness between the part 54B of the thread 54A of the inner plate 6 and the male screw portion 42 of the male screw shaft 5 is improved. Also by this, the sealing performance between the inner tray 6 and the container body 2 is improved.

As the intermediate dish 6 rises, the contents accommodated in the container body 2 pass through the gaps between the flow holes 34 </ b> A and the mounting plate portion 23 and the connecting plate portion 34 formed in the connecting plate portion 34 of the operation member 4. And flows into the discharge cylinder 24. And it raises the inside of the discharge cylinder part 24, and is discharged in the application member 25 from 3A of discharge holes. The valve member 26 opens the discharge hole 3A by the pressure of the discharged content. Thereby, the contents in the container body 2 are discharged and impregnated in the application member 25. The application member 25 applies the impregnated content to the application portion.
As described above, the contents are applied to the application portion using the feeding container 1.

  According to the feeding container 1 configured as described above, a part 54B of the thread 54A of the female screw part 54 is in close contact with the male screw part 42, and the sliding part 52A is the inner peripheral surface of the container main body 2. Therefore, it is possible to prevent the contents located above the middle dish 6 in the container body 2 from leaking downward from the middle dish 6. At this time, since the part 54B formed on the elastic material portion 6B is pressed against the male screw portion 42, the sealing performance between the male screw shaft 5 and the inner plate 6 is reliably ensured. Compared with the case where fins as described are provided, the sealing performance can be maintained over a long period of time. Furthermore, since only the part 54B, not the entire thread 54A, is formed in the elastic material portion 6B, an increase in rotational torque of the male screw shaft 5 can be suppressed.

Further, since the female screw portion 54 is pressed against the male screw portion 42 by the reaction force against the sliding portion 52A pressing against the inner peripheral surface of the container main body 2, the above-mentioned one of the thread 54A in the female screw portion 54 is pressed. The adhesion between the portion 54B and the male screw portion 42 is improved, and the sealing performance between the male screw shaft 5 and the inner plate 6 is improved. Here, since the frictional resistance between the sliding portion 52A and the container body 2 is increased by the sliding portion 52A being pressed against the inner peripheral surface of the container body 2, the female screw portion 54 and the male screw portion 42 are Even when the frictional resistance between them increases, the inner plate 6 can be prevented from rotating together with the male screw shaft 5 when the male screw shaft 5 is rotated around the container axis O.
Furthermore, by forming the part 54B of the screw thread 54A and the sliding part 52A integrally with the same material, the part 54B and the sliding part 52A can be easily and accurately formed.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, as shown in FIG. 6, the sliding cylinder portion 101 of the inner dish 100 may be in sliding contact with the inner peripheral surface of the container body 2 over the entire length in the vertical direction, and the entire outer peripheral edge portion of the sliding cylinder portion 101. Functions as the sliding portion 101A. Thereby, the adhesiveness between the inner tray 100 and the inner peripheral surface of the container body 2 is further improved. For example, when the viscosity of the contents is low, the contents are in contact with the sliding cylinder portion 101 of the inner dish 100 and the container. It is possible to more reliably prevent leakage through the space between the inner peripheral surface of the main body 2.

  Further, as shown in FIG. 7, the sliding cylinder portion 111 of the inner tray 110 has a peripheral rib portion 111B that protrudes radially outward between the pair of sliding portions 111A in the vertical direction. Also good. The circumferential rib portion 111B is formed of a material that can be elastically deformed in the same manner as the sliding portion 111A. Thereby, compared with the sliding cylinder part 101 shown in FIG. 6, the male screw axis | shaft 5 moves to an up-down direction, improving the sealing performance between the container main body 2, the male screw axis | shaft 5, and the inner tray 6. FIG. It can suppress becoming difficult. Note that a plurality of the circumferential rib portions 111B may be formed at intervals in the vertical direction, for example, depending on the viscosity of the contents, and the length in the vertical direction may be appropriately changed.

Furthermore, the inner diameter of a part of the screw thread in the female screw part is smaller than the inner diameter of the other part, but the inner diameter of a part of the screw valley in the female screw part is smaller than the inner diameter of the other part. It may be small.
The above-mentioned part of the thread in the female thread part is formed in a portion of 1 mm or more and 2 mm or less at the beginning of threading. If it is a part of the thread, it is formed in a portion of 1 mm or more and 2 mm or less at the end of threading. It may be formed in other parts such as a middle part of the screw thread. The length of the part along the thread is not limited to 1 mm or more and 2 mm or less.
The above-mentioned part of the screw thread in the female screw part is in contact with the male screw part over the entire length in the vertical direction in a cross-sectional view in the vertical direction. As long as it is smaller than the inner diameter, it does not have to be in contact with the male screw portion over the entire length in the vertical direction.
A part of the screw thread or screw valley in the female screw part and the sliding part are integrally formed of the same material, but the part and the sliding part may be formed separately, Alternatively, it may be formed of another material. Similarly, the peripheral rib portion may be formed as a separate body from the sliding portion, or may be formed of a material different from the sliding portion.
The sliding cylinder portion is provided with a pair of sliding portions. However, it is sufficient that at least one sliding portion is provided, and three or more sliding portions may be provided.
The operating member is connected to the upper end of the male screw shaft, but if it is exposed to the outside of the container body and can be rotated, it can be connected to other parts of the male screw shaft, such as the lower end of the male screw shaft. May be. Moreover, you may abbreviate | omit an operation member by setting it as the structure which can operate a male screw axis | shaft directly.
The container body, the discharge member, the operation member, and the inner tray are not limited to a cylindrical shape, and may be other shapes such as an elliptical cylindrical shape.

  According to this invention, industrial applicability is recognized regarding the delivery container which improved the sealing performance between an inner tray, a container main body, and a male screw shaft.
