Description

  The present invention relates to an adapter for an agitation deaerator.

  In general, there is known a stirring and defoaming device configured to revolve on a revolution orbit while holding a container holding a material to be kneaded on a container holder and revolving (see, for example, Patent Document 1). In this type of stirring and defoaming device, the material to be kneaded is pressed against the inner wall of the container by centrifugal force acting by the revolution of the container, and bubbles contained in the material to be kneaded are released to the outside, and the container is rotated by the rotation of the container. The product to be kneaded is stirred. Specifically, it has been clarified that when the revolution speed of the container is high, the defoaming performance of the material to be kneaded is improved, and when the rotation speed is high, the stirring performance is improved.

In recent years, such a stirring deaerator is used for stirring and defoaming ointments. The ointment is stirred and defoamed in a state where the container (ointment container) is filled, but the size of the container (ointment container) filled with the ointment varies, and each container has an adapter corresponding to the size. It was set in the container holder of the stirring deaerator. In particular, a container having a small external dimension cannot be accommodated by one adapter, and the current situation is that the adapter is accommodated through another adapter mounted in the adapter, that is, the adapter is doubled.

For example, an ointment container 3 (accommodating container) filled with an ointment is set in the container holder 15 via the adapter 2. In the present embodiment, the ointment container 3 is assumed and described. However, the present invention is not limited to this, and can be applied to the case of holding a storage container that stores various materials to be kneaded. .

FIG. 2 is a cross-sectional view of the adapter according to the present embodiment holding a small-sized ointment container.
As shown in FIG. 2, the adapter 2 includes a bottomed cylindrical container main body 21 having one end opened, a container lid 22 covering the opening of the container main body 21, and a pressing member 23 attached to the container lid 22. Composed.

  The container main body 21 is a container for housing the ointment container 3, and is formed so as to be fitted in the container holder 15 (see FIG. 1). A circular bottom member 211 is disposed at the inner lower portion of the container body 21. The bottom member 211 is a ring-shaped member in plan view, and the inner peripheral surface 211b of the central opening 211a is formed in a shape (tapered) that decreases in diameter from top to bottom. Moreover, the upper end outer peripheral part 212 of the container main body 21 is formed so that the container cover 22 which covers an opening part can be screwed. Incidentally, in this embodiment, although the container main body 21 was comprised so that insertion in the container holder 15 was carried out, the container main body 21 should just be fixed in the container holder 15, and does not need to be a fitting type. In the present embodiment, the inner peripheral surface 211b of the bottom member 211 and the bottom surface 21a of the container body 21 correspond to a “bottom” in the claims.

  The container lid 22 seals the container main body 21 and is configured by attaching a thick member 221 to the lower surface side. A through hole 221a is formed at the center of the thick member 221, and a screw groove is formed on the inner peripheral surface of the through hole 221a.

  The pressing member 23 is attached with an attachment shaft 231 attached to the container lid 22, a pressing portion 232 attached to the lower end side of the attachment shaft 231 via a washer W, and a bolt B on the upper end side of the attachment shaft 231. And a grip portion 233.

  The attachment shaft 231 is formed so as to be able to be screwed into a through hole 221a located on the central axis of the container lid 22, whereby the pressing member 23 itself can be moved forward and backward toward the bottom surface 21 a side of the container body 21. Yes. Further, a small diameter portion 231a having a small diameter is provided at the tip of the attachment shaft 231 so that the pressing portion 232 is inserted and attached.

  The pressing part 232 is a disk-like member in plan view, and the outer peripheral edge part 232a on the lower surface thereof is formed so as to protrude downward. The inner peripheral surface 232b of the outer peripheral edge portion 232a is formed in a shape (tapered shape) that decreases in diameter from the lower side to the upper side. In addition, a through hole 232 c is formed at the center of the pressing portion 232. The pressing portion 232 is configured such that the small diameter portion 231a is inserted into the through hole 232c and attached to the attachment shaft 231 with a bolt B via a washer W. Note that the length of the through hole 232c is slightly shorter than the length of the small diameter portion 231a.

  The grip portion 233 is for making the attachment shaft 231 easy to rotate, and is fixed to the upper portion of the attachment shaft 231 with two bolts B.

  The ointment container 3 is held by the adapter 2 configured as described above as follows. First, the ointment container 3 is a circular container having various sizes, and here, a container of a minimum size having a diameter smaller than that of the opening 211a of the bottom member 211 is assumed.

  After the ointment container 3 is placed on the bottom surface 21a of the container body 21, the container lid 22 is screwed. Then, by gripping and rotating the grip portion 233, the attachment shaft 231 is screwed and the pressing portion 232 advances downward. At this time, even if the ointment container 3 is in a position deviated from the central part of the container body 21, the upper peripheral edge of the ointment container 3 is formed by the inner peripheral surface 232b of the pressing part 232 being tapered. When it comes into contact with the part, it acts to shift its position to the center part. As a result, the center of the ointment container 3 is positioned so as to coincide with the center axis of the adapter 2 and eventually overlap the rotation axis of the container holder 15. And the ointment container 3 is clamped between the press part 232 and the bottom face 21a in the state positioned in this way. Since the pressing portion 232 is formed shorter than the small-diameter portion 231a of the mounting shaft 231, when the mounting shaft 231 is further lowered downward after the pressing portion 232 contacts the ointment container 3, the pressing portion 232 is pressed. Is relatively pushed up and the upper surface thereof comes into contact with the stepped portion 231b. That is, after the pressing portion 232 comes into contact with the ointment container 3, it does not follow the rotation of the mounting shaft 231 and does not slide with the ointment container 3.

Moreover, when making this adapter 2 hold | maintain large ointment container 3 'whose diameter is larger than the opening part 211a of the bottom part member 211, it is as follows. FIG. 3 is a cross-sectional view of the adapter according to the present embodiment holding a large-sized ointment container.
After placing the large-sized ointment container 3 ′ on the inner peripheral surface 211 b of the bottom member 211, the container lid 22 is screwed. Then, by gripping and rotating the grip portion 233, the attachment shaft 231 is screwed and the pressing portion 232 advances downward. At this time, even if the ointment container 3 is in a position deviated from the central portion of the container main body 21, the inner peripheral surface 211b of the bottom member 211 is formed in a tapered shape, so that the pressing portion 232 becomes the ointment container. When pressing 3 from above, it acts to shift the position of the ointment container 3 to the center along the tapered surface of the inner peripheral surface 211b. Thus, the ointment container 3 is positioned so that the center of the ointment container 3 coincides with the center axis of the adapter 2 and eventually overlaps with the rotation axis of the container holder 15. Then, the ointment container 3 ′ is sandwiched between the pressing portion 232 and the bottom member 211 while being positioned in this way.

  Then, the adapter 2 holding the ointment container 3 in this way is set in the container holder 15 of the stirring and defoaming device 1. The stirring and defoaming device 1 rotates the container holder 15 by rotating around the rotation axis 14 while rotating around the rotation axis 14 while rotating around the rotation axis 12. Thereby, the ointment filled in the ointment container 3 can be stirred and defoamed.

According to the above, the following effects can be obtained in the present embodiment.
According to the adapter 2 which concerns on this embodiment, the ointment container 3 of various sizes can be hold | maintained easily. Thereby, the trouble of selecting the adapter 2 according to the size of the ointment container 3 can be saved, and the storage space can be reduced.

  According to the adapter 2 according to the present embodiment, the ointment container 3 is pressed and sandwiched between the bottom of the container body 21 and the pressing member 23 from above and below, so that the ointment container 3 has poor sealing properties. Also, leakage of the filled ointment can be prevented. Moreover, even if it is a case where it leaks, it will only stay in the container main body 21. That is, since it does not adhere to each mechanism of the stirring deaerator 1, the stirring deaerator 1 can be prevented from malfunctioning. Furthermore, if the ointment leaks, it is easy to handle because only the adapter 2 needs to be washed.

  Since the inner peripheral surface 211b of the container main body 21 and the inner peripheral surface 232b of the pressing portion 232 of the pressing member 23 are formed so as to be recessed in a tapered shape, the ointment container 3 to be held can be positioned at the central portion. Thereby, since the ointment container 3 is positioned so as to overlap with the rotation axis of the container holder 15, when it is set in the stirring deaerator 1, an efficient stirring defoaming effect can be obtained.
