[First Embodiment]
Hereinafter, the embodiment of the container 3 in which the refill body 2 is refilled by the refill set 1 and the refill set 1 of the present invention will be described in detail with reference to the drawings.
1 to 7 schematically show the refilling procedure using the refill set 1 and the respective components constituting the refill set 1 and the container 3 for the refill set 1 of the first embodiment. .

First, the refilling procedure of the refill body 2 using the refill set 1 of the first embodiment will be described with reference to FIG.
As shown in FIG. 1, a container 3 to be refilled by the refill set 1 of the present invention can be removably attached with a refill body 2 containing the contents in the container. For example, when the content contained in the refill body 2 is used up and the used refill body 2U used up is replaced with a new one (new refill body 2N), the refill set 1 as shown in the first embodiment is used. Used. That is, the refilling procedure of the refill body 2 shown in FIG. 1 is a series of operation procedures for refilling the used refill body 2U accommodated in the container body 4 into the new refill body 2N using the refilling set 1 of the first embodiment. It is to show.

  In the following description, the refill body 2 in which the contents are used up and the inside is empty is referred to as “used refill body 2U”. In addition, the refill body 2 that is newly refilled using the refill set 1 (the refill body 2 filled with new contents) is referred to as a “new refill body 2N”, and the two are shown separately. Furthermore, there are cases where the used refill body 2U and the new refill body 2N are both simply referred to as "refill body 2" as a term that expresses them in a superordinate concept.

  Furthermore, when the container 3 is illustrated in FIGS. 1, 14, and 15, the container body 4 and the container lid 5 that are actually used by storing cosmetics or the like are both provided with a handle (in the illustrated example, a flower rhombus is used). It is shown in the appearance of the printed one). This is because the container body 4 and the container lid 5 are often subjected to elaborate decoration and printing, as represented by luxury cosmetics, etc., and the plain refill lid 6 used in the refill set 1 etc. This is because there are many differences in appearance.

To deepen the understanding of the present invention, first, a procedure for performing refilling using the refill set 1 of the first embodiment will be described first.
When refilling using the refill set 1, a refill set 1 containing a new refill body 2N as shown in FIG. The refill set 1 has two members: a new refill body 2N for storing contents such as cosmetics, and a refill lid 6 capable of closing the opening at the top of the new refill body 2N. .

  As shown in FIG. 1B, when the refill set 1 is prepared, the refill lid 6 is removed from the prepared refill set 1, and the refill lid 6 and the new refill body 2N are separated separately. In the case of the first embodiment, since the refill lid 6 is screwed and attached to the new refill body 2N, the refill lid 6 is removed from the refill set 1 by rotating the refill lid 6 in the direction opposite to that at the time of attachment. Can be removed.

  As shown in FIG. 1C, the refill lid 6 removed from the refill set 1 can be attached to the used refill body 2 </ b> U of the container body 4. That is, although the used refill body 2U and the new refill body 2N are different in the remaining amount of contents, the shape and structure are the same standard, so the refill lid 6 is only the new refill body 2N. It can also be attached to the used refill body 2U. Therefore, if the refill lid 6 removed from the refill set 1 is screwed into the used refill body 2U accommodated in the accommodating portion 7 inside the container body 4, the refill lid 6 is used. Can be attached to.

  Here, a fixing means 8 for fixing the used refill body 2U to the accommodating portion 7 is provided between the container body 4 and the used refill body 2U, and the used refill body. 2U is fixed to the accommodating portion 7 (container body 4) using a fixing means 8. In the refill lid 6 of the first embodiment, the removal means 9 that releases the above-described fixing means 8 and enables the used refill body 2U to be removed from the housing portion 7 (see, for example, FIG. 3). Is provided. The detaching means 9 is configured to release the engagement of the fixing means 8 in accordance with an operation for screwing the refill lid 6 to the container body 4.

Therefore, as shown in FIG. 1 (d), when the refill lid 6 is screwed and attached to the container body 4, the removal means 9 releases the engagement of the fixing means 8, and the used refill body 2U is accommodated. It will be in the state which can be removed from the part 7 (free state).
Here, the used refill body 2 </ b> U that has been disengaged is in a state (separated state) that is separable from the housing portion 7, and can be pulled out from the housing portion 7.

  The refill lid 6 is also provided with an integration means 10 for integrating the used refill body 2U with the refill lid 6. In the first embodiment, the integration means 10 is configured by a member for performing the above-described screwing, that is, a first screw portion 11 and a second screw portion 12 (see FIG. 3) described later. Therefore, if the refill lid 6 is lifted, the used refill body 2 integrated with the refill lid 6 by the integration means 10 can be pulled out from the accommodating portion 7 together with the refill lid 6.

Therefore, as shown in FIG. 1 (e), when the refill set 1 of the first embodiment is used, the used refill body 2 </ b> U removed from the container body 4 is put together with the refill lid 6 into the container body. 4 and can be discarded together with the refill lid 6.
As shown in FIG. 1 (f), in the container main body 4 from which the used refill body 2U has been removed, the housing portion 7 is empty, and a state in which preparations for receiving the new refill body 2N are complete. It has become. Therefore, if the new refill body 2N removed in FIG. 1B is pushed into the housing portion 7 from above, the new refill body 2N cannot be removed from the housing portion 7 (container body 4) using the fixing means 8 described above. It becomes possible to fix so.

If the container lid 5 is screwed onto the new refill body 2N fixed to the container body 4 in this way, the container 3 that has been refilled to the new refill body 2N as shown in FIG. 1 (g). Can be obtained.
The above is the refilling procedure using the refill set 1 of the first embodiment.
In the container 3 that has been refilled with the new refill body 2N described above, the container lid 5 is screwed onto the new refill body 2N, so that the container lid 5 can be rotated by rotating the container lid 5 clockwise, for example. It is possible to use the contents after removing the container, and if the container is turned counterclockwise, the container lid 5 can be closed and the contents of the new refill body 2N can be stored safely and hygienically, and the container 3 can be opened and closed. It can be used freely.

Next, the container 3 in which refilling is performed using the refill set 1 of the first embodiment described above will be described.
The container 3 according to the first embodiment includes a container main body 4 provided with an accommodating portion 7 that can accommodate the refill body 2 inside, and a container main body 4 (more precisely, the refill body 2 accommodated in the container main body 4). On the other hand, it is a combination of upper and lower two members, a container lid 5 provided detachably.

As shown in FIG. 4, the container main body 4 is formed in a bottomed cylindrical shape using synthetic resin, metal, earthenware, or the like, and has an accommodating portion 7 that can accommodate the refill body 2 therein. The accommodating portion 7 is a cylindrical space that opens upward, and can be accommodated by inserting the refill body 2 from above.
And the container 3 of 1st Embodiment is provided with the fixing means 8 which fixes the inserted refill body 2 to the accommodating part 7. FIG. The fixing means 8 includes an engaging protrusion 13 provided on the upper end side of the container main body 4 (opening portion of the accommodating portion 7), and an engaging tongue 14 that engages with the engaging protrusion 13 (on the refill body 2 described later). And an engaging tongue 14) provided.

Specifically, on the outer peripheral surface on the upper end side of the container body 4 described above, there are an engagement protrusion 13 protruding toward the radially outer side and a vertical groove 18 that is recessed toward the radially inner side and extends in the vertical direction. They are formed at different positions. This engagement protrusion 13 is one of the members constituting the fixing means 8 described above.
The fixing means 8 described above is for fixing the refill body 2 to the container body 4 so as not to move in the vertical direction. The fixing means 8 of the first embodiment engages the engaging protrusion 13 of the container main body 4 with the engaging tongue 14 provided on the used refill body 2U or the new refill body 2N from the outside of the diameter. Both members are fixed and engaged.

  The engagement protrusions 13 are provided at two locations (two locations positioned at an angle of 180 ° with respect to the center of the container body 4) across the center of the container body 4 on the outer peripheral surface on the upper end side of the container body 4 described above. Each is formed. Each engaging protrusion 13 is a protruding piece that protrudes outward in the radial direction so that a cross section cut along the horizontal direction has a triangular shape. That is, the engagement protrusion 13 has two surfaces, a surface that faces clockwise when viewed from above (hereinafter referred to as a guide surface 19) and a surface that faces counterclockwise (hereinafter referred to as a support surface 20). have. The guide surface 19 described above is a continuous inclined surface that is gently inclined with respect to the outer peripheral surface, and the support surface 20 is inclined with respect to the outer peripheral surface at a steeper angle than the guide surface 19. A hook-like engagement piece 21 is formed on the upper side of the guide surface 19 of the engagement protrusion 13 so as to protrude toward the radially outer side. For this reason, when the engaging tongue portion 14 is engaged with the guide surface 19 on the lower side of the engaging piece 21 so as to be in a surface contact state, the engaging piece 21 that protrudes above the guiding surface 19 is engaged. The upward movement of the tongue portion 14 is restricted, and the refill body 2 provided with the engagement tongue portion 14 is fixed so as not to move upward with respect to the container body 4 provided with the engagement piece 21.

  On the other hand, the vertical groove 18 described above is a portion of the outer peripheral surface on the upper end side of the container main body 4 that is a portion in which only a part of the circumferential direction is recessed in the shape of a surface toward the inside of the diameter. Similarly, it is formed at two locations across the center of the container body 4. The vertical groove 18 is linearly formed along the vertical direction from the lower end to the upper end of the outer peripheral surface, and a positioning portion 22 provided on the refill body 2 and the new refill body 2N described later can move in the vertical direction. Can be loosely fitted. By forming the vertical groove 18 of the container body 4 as described above, the refill body 2 or the new refill body 2N can be inserted into a predetermined position in the circumferential direction of the housing portion 7, and the engaging tongue portion 14 of the refill body 2 can be inserted. This position can be reliably matched with the position of the engagement protrusion 13 of the container body 4, and both members can be reliably engaged.

  The container lid 5 is a member that can close the opening of the container body 4 described above. The container lid 5 of the present embodiment has almost the same shape and configuration as a refill lid 6 described later. The container lid 5 is different from the refill lid 6 in that the container lid 5 does not have a release piece 23 (removing means 9) described later. Therefore, in this specification, the configuration of the container lid 5 will be described with reference to FIG. 3 showing the refill lid 6 having almost the same shape, but the release piece 23 shown in FIG. Not provided.

As shown in FIG. 3, the container lid 5 (symbol 6 in FIG. 3) is a member formed in a covered cylindrical shape, and the opening of the container main body 4 described above can be closed from above.
Specifically, the container lid 5 includes a disc-shaped canopy portion 24 (reference numeral 29 in FIG. 3) arranged along the horizontal direction, and a short cylindrical shape that hangs downward from the outer edge of the canopy portion 24. The outer wall portion 25 (reference numeral 30 in FIG. 3), and an inner wall portion 26 that hangs downward from the lower surface of the canopy portion 24 inside the outer wall portion 25 and has a shorter cylindrical shape than the outer wall portion 25. (Reference numeral 31 in FIG. 3). The outer diameter of the canopy portion 24 (the outer diameter of the outer wall portion 25) is substantially equal to the outer diameter of the container body 4 described above (exactly, the outer diameter of the lower side of the container body 4). The outer diameter is substantially equal to the outer diameter of the refill body 2.

And the 2nd screw part 12 which can be screwed by the 1st screw part 11 (screw part provided in the opening part vicinity of the refill body 2) mentioned later on the internal peripheral surface (surface which faces a diameter inner side) of the inner wall part 26 is demonstrated. Is formed.
Next, the refill set 1 used when the used refill body 2U is refilled with the new refill body 2N will be described.

The refill set 1 of the first embodiment is used when refilling a used refill body 2U attached to the accommodating portion 7 with a new refill body 2N, and a new refill body 2N that is newly refilled into the accommodating portion 7. And a refill lid 6 that closes the opening of the new refill body 2N.
As shown in FIG. 2, the refill body 2 is formed in a bottomed cylindrical shape that is opened upward using a synthetic resin or the like, and contains contents such as solid or semi-solid cosmetics and medicines on the inside. It is what was contained. The refill body 2 is formed of a material cheaper than the material constituting the container body 4, for example, an engineering plastic such as polypropylene, polyethylene, or polystyrene.

Moreover, although the content (accommodation thing) accommodated in the refill body 2 mentioned above is mainly cosmetics, a pharmaceutical, etc. which were mentioned above, it is not limited to these. For example, you may use in any field | areas, such as a foodstuff, household miscellaneous goods, camping goods, and pet goods.
Further, as described above, the used refill body 2U and the new refill body 2N have a difference in the presence or absence of contents, but there is no difference in the shape and structure of the container 3 itself.

  Specifically, the above-described refill body 2 projects on the outer peripheral surface on the midway in the vertical direction so as to project horizontally toward the radially outer side, and further downward from the projected edge (end on the radially outer side). A flange portion 27 that hangs down like a bowl is formed. The flange portion 27 is formed so as to surround the entire periphery of the refill body 2 (so as to be annular when viewed from above). An engagement tongue portion 14 that is one of the members constituting the fixing means 8 is formed at a portion of the flange portion 27 that hangs down in a bowl shape. In addition, a positioning portion 22 that loosely fits in the longitudinal groove 18 of the container body 4 is also formed on the outer peripheral surface of the refill body 2 covered with the portion that hangs down in a bowl shape.

Furthermore, the 1st thread part 11 is formed in the outer peripheral surface of the refill body 2 located above the flange part 27 mentioned above, The screw of the 2nd thread part 12 of the container lid 5 or the refill lid 6 mentioned above is carried out. Is possible.
The above-mentioned engaging tongue portion 14 is formed with a notch that is L-shaped when viewed from the outer side of the flange portion 27 and has an arc shape when viewed from above. It is formed in such a long tongue shape. The engaging tongue portion 14 is fixed to the flange portion 27 at the proximal end side, but is separated from the flange portion 27 at the distal end side, and the distal end side can be elastically deformed in the radial direction with respect to the proximal end side. ing.

That is, when the distal end side of the engaging tongue portion 14 is curved to the radially outer side than the flange portion 27, an elastic restoring force acts on the distal end side of the engaging tongue portion 14 toward the radially inner side. By this restoring force, the distal end side of the engaging tongue portion 14 is pressed toward the inside of the diameter, and the engaging tongue portion 14 is engaged with the engaging protrusion 13 using the pressing force.
Specifically, the engaging tongue portion 14 described above engages so that the midway side in the longitudinal direction is along the guide surface 19 of the engaging protrusion 13. At this time, since the engagement piece 21 provided on the upper side of the guide surface 19 protrudes to the outside of the diameter from the engagement tongue portion 14, the engagement projection 13 moves upward and the engagement tongue portion 14 moves upward. I can't. Therefore, the upward movement of the refill body 2 with respect to the housing portion 7 is restricted, and the refill body 2 can be engaged with and fixed to the housing portion 7 without moving up and down.

  On the other hand, an upright piece 28 is formed at the distal end of the engaging tongue 14 so as to protrude outward from the outer peripheral surface of the flange 27 so that the engaging tongue 14 can be easily separated when the engagement is released. ing. The standing piece 28 is a member provided so as to protrude further radially outward from the distal end of the engaging tongue portion 14, and the distal end is located on the radially outer side than the outer peripheral surface of the flange portion 27. Therefore, when releasing the engaging tongue 14 engaged with the engaging protrusion 13 described above, the upright piece 28 is moved in the clockwise direction when viewed from above. If it does so, it will rock | fluctuate so that the engagement tongue part 14 may be raised toward the diameter outer side, the front-end | tip of the engagement tongue part 14 will leave | separate from the engagement protrusion 13, and the middle side of the engagement tongue part 14 may be engaged. Since it comes to be located inside the diameter of the joint 13, the refill body 2 is allowed to move upward with respect to the housing portion 7, and the refill body 2 can be easily moved upward from the housing portion 7.

  Further, the insertion position of the refill body 2 with respect to the container body 4, more precisely, is fixed to the outer peripheral surface of the refill body 2 (enclosed by the flange portion 27) located further on the inner peripheral side of the flange portion 27 described above. A positioning portion 22 is provided for engaging the engaging tongue portion 14 of the means 8 at a predetermined circumferential position. Specifically, the positioning portion 22 is formed on the outer peripheral surface of the refill body 2 so that the width along the circumferential direction is narrower than the longitudinal groove 18 of the container body 4, and protrudes toward the radially outer side. The refill body 2 is movable in the vertical direction with respect to the container body 4 and can be engaged with the vertical groove 18 in a state in which circumferential rotation is restricted.

In addition, the shape of the positioning portion 22 and the vertical groove 18 is not particularly limited to a quadrangle, and may be a shape other than a quadrangle (for example, a circle or an oval). Moreover, the position of the vertical groove 18 of this embodiment may be either inside or outside the container body 4. However, the refill body 2 also needs to have a shape that matches the vertical groove 18.
As shown in FIG. 3, the refill lid 6 is a member formed in a covered cylindrical shape like the container lid 5, and in the refill set 1, the opening of the new refill body 2 </ b> N is closed. Specifically, the refill lid 6 has an outer diameter that further exceeds the outer diameter required to close the opening of the new refill body 2N, in other words, an outer diameter that is substantially equal to the container body 4. .

Specifically, the refill lid 6 includes a disc-shaped blocking portion 29 provided along the horizontal direction, a refill outer wall portion 30 that hangs downward from an outer edge of the blocking portion 29, and a refill outer wall portion 30. And a refill inner wall portion 31 that hangs downward from the lower surface of the closing portion 29 on the inner peripheral side.
Further, the refill lid 6 described above includes a removing means 9 for switching the refill body 2 fixed to the container body 4 by the fixing means 8 from a fixed state to a removable state, and a refill body switched to a free state. And an integration means 10 for integrating 2 with the refill lid 6. And it is the characteristics of the refill set 1 of this invention that three members, the obstruction | occlusion part 29, the removal means 9, and the integration means 10, are provided in the refill lid | cover 6. FIG.

Next, the closing part 29 of the refill lid 6, the removing means 9, and the integrating means 10, which are features of the refill set 1 of the first embodiment, will be described.
The closing part 29 is formed in a disk shape like the canopy part 24 of the container lid 5. The outer diameter of the closing portion 29 is formed larger than the outer diameter of the used refill body 2U or the new refill body 2N, and the opening of the refill body 2 can be closed. A second threaded portion 12 that can be screwed into the first threaded portion 11 of the refill body 2 is formed on the inner peripheral surface (the surface facing the radially inner side) of the inner wall portion 26. Therefore, when the second screw portion 12 is screwed to the first screw portion 11, the closing portion 29 covers the opening of the refill body 2 without leaving the refill body 2. The part 44 is closed.

As shown in the elevation view and the cross-sectional view of FIG. 3, the detaching means 9 is a member capable of releasing the engagement of the engagement tongue portion 14 with respect to the engagement protrusion 13 and is formed on the refill lid 6 in the present invention. The release piece 23 constitutes the removing means 9.
When attaching the refill lid 6 to the container body 4 and the refill body 2 shown in FIG. 5, the operation is performed according to the procedure shown in FIGS. 6 and 7.

That is, as shown in FIG. 6, the release piece 23 of the first embodiment protrudes inward from the inner peripheral surface of the refill outer wall portion 30, and the protruding end is an upright piece of the engaging tongue portion 14 described above. It is located on the inner diameter side than 28.
Therefore, as shown in FIG. 7, when the refill lid 6 is rotated to a predetermined rotation position with respect to the refill body 2, the above-described release piece 23 comes into contact with the upright piece 28, and the upright piece 28 is outside the diameter ( In order to push up in the releasing direction, the fixing by the fixing means 8 (engagement to the engaging protrusion 13 by the engaging tongue 14) is released.

Since the refill body 2 that has been released by the release piece 23 in this manner is separable from the housing portion 7 of the container body 4, it can be moved upward and can be removed from the housing portion 7. It becomes possible.
In the present embodiment, the release piece 23 is one that protrudes from the inner peripheral surface of the refill outer wall portion 30 toward the inside of the diameter, but a release piece 23 that extends downward from the lower surface of the closing portion 29 is employed. Also good.

The integration means 10 refills the refill body 2 in order to pull out the refill body 2 that has been disengaged by the release piece 23 (removal means 9) described above and switched to the released state from the accommodating portion 7 together with the refill lid 6. It is integrated with the lid 6.
Specifically, the integration means 10 used in the refill set 1 of the first embodiment integrates the refill lid 6 with the refill body 2 by screwing. That is, the integration means 10 of the first embodiment is formed on the inner peripheral surface of the first screw portion 11 formed on the upper end side of the outer peripheral surface of the refill body 2 and the refill outer wall portion 30 of the refill lid 6. , And the second screw portion 12 that can be screwed to the first screw portion 11.

  That is, when the engagement is released using the integration unit 10 described above, the refill lid 6 is rotated with respect to the container body 4. Then, in accordance with the releasing operation of the fixing means 8, the second thread formed on the inner peripheral surface of the refill inner wall portion 31 of the refill lid 6 is formed on the first screw portion 11 formed on the outer peripheral surface on the upper end side of the refill body 2. The screw portion 12 is screwed, so that the refill body 2 can be integrated with the refill lid 6, and the refill body 2 can be pulled out from the accommodating portion 7 together with the refill lid 6.

If the refill set 1 of the first embodiment described above is used, the refill lid 6 of the new refill body 2N used for protecting the contents, the function of releasing the fixing means 8, and the used refill body 2U as the container body 4 Can be used to remove the used refill body 2U from the container 3 and to take the used refill body 2U out of the container 3, and the refill lid 6 has a plurality of functions. It becomes possible to keep it low, and the structure becomes simple. Therefore, it is possible to obtain a refill set 1 in which the refill body 2 containing the contents can be easily replaced while having a simple structure and low processing cost.
[Second Embodiment]
Next, the refill set 1 of 2nd Embodiment is demonstrated using drawing.

  In the first embodiment described above, the engaging tongue 14 of the refill body 2 is engaged from the radially outer side with the engaging protrusion 13 of the container body 4 protruding toward the radially outer side, and the engagement projecting outward from the radially outer side. The refill body 2 was fixed to the accommodating portion 7 of the container body 4 by hooking the engaging tongue portion 14 on the combined piece 21. However, in the refill set 1 of the second embodiment, the engagement protrusion 13 protrudes radially inward from the container body 4 and the engagement tongue 14 positioned on the diameter inner side with respect to the engagement protrusion 13 protruding radially inward. Is engaged and engaged.

Further, in the refill set 1 of the second embodiment, the direction in which the release piece 23 acts is also different from the difference in the engagement direction, and when the engagement of the engagement tongue portion 14 is released by the release piece 23, The joint tongue 14 is pushed back to the inside of the diameter instead of the outside of the diameter, and the engagement of the engaging tongue 14 is released.
Next, each member which comprises the refill set 1 of 2nd Embodiment is demonstrated.

First, the container main body 4 which comprises the container 3 of 2nd Embodiment is demonstrated.
As shown in FIG. 10, the container body 4 of the second embodiment is formed into a bottomed cylindrical shape using synthetic resin, metal, etc., as in the first embodiment, and the used refill body inside It has the accommodating part 7 which can accommodate 2U and the new refill body 2N. The container body 4 of the second embodiment is different in the structure of the upper end, in other words, the structure of the opening edge of the accommodating portion 7 from the difference in the engaging direction.

And the 1st slit 33 and the 2nd slit 34 which were cut in the downward direction from the upper end surface are formed in the upper end side of the container main body 4 mentioned above.
The first slit 33 described above can insert the upright piece 28 formed at the tip of the engaging tongue 14 from the radially outer side toward the radially inner side. The first slits 33 open upward at two locations (two locations positioned at an angle of 180 ° with respect to the center of the container body 4) sandwiching the center of the container body 4 at the upper end of the container body 4. It is formed as a substantially U-shaped groove.

  The opening width along the circumferential direction of the first slit 33 is formed to have a dimension approximately equal to the width of an upright piece 28 of the engaging tongue 14 to be described later, and is a size into which the upright piece 28 can be inserted. . Further, the thickness along the radial direction of the first slit 33 is shorter than the thickness along the radial direction of the upright piece 28, and can penetrate the upright piece 28 in the radial direction. The vertical depth of the first slit 33 is formed to be deeper than the vertical thickness of the upright piece 28, and the upright piece 28 is inserted in the first slit 33 in the vertical direction. Are dimensioned to be movable.

  Similar to the first slit 33, the second slit 34 is formed at two locations sandwiching the center of the container body 4 at the upper end of the container body 4. The second slit 34 is provided at a position at an angle of 90 ° with respect to the first slit 33 described above with the center of the container main body 4 as a reference, and the first slit 33 and the first slit 33 around the center of the container main body 4. The second slits 34 are arranged alternately every 90 °. In the present embodiment, the first slits 33 and the second slits 34 are alternately arranged around the center of the container body 4 every 90 °, but the arrangement of the first slits 33 and the second slits 34 is It does not have to be every 90 °. For example, an angle other than 90 ° such as 45 °, 60 °, and 180 ° may be used.

  Further, an engagement protrusion 13 that engages with the engagement tongue portion 14 and restricts the upward movement of the engagement tongue portion 14 is formed on the opening edge inside the diameter of the first slit 33. Unlike the first embodiment, the engagement protrusion 13 of the second embodiment is formed on the inner peripheral surface of the container body 4 adjacent to the first slit 33 in the clockwise direction when viewed from the upper side, unlike the first embodiment. It is formed so as to protrude toward.

Specifically, the engagement protrusion 13 slightly protrudes from the inner peripheral surface on the upper end side of the container body 4 further toward the inside of the diameter, and is hooked on the midway side in the longitudinal direction of the engagement tongue 14. In this configuration, the upward movement of the refill body 2 is restricted. Further, unlike the first embodiment, the engagement protrusion 13 of the second embodiment does not have to be wedge-shaped and only needs to protrude inward in the diameter.
As shown in FIG. 8, the refill body 2 of 2nd Embodiment is formed in the bottomed cylindrical shape opened upwards similarly to 1st Embodiment, and can accommodate the content inside. ing. Specifically, a flange that protrudes in the horizontal direction so as to project outward toward the radially outer side of the refill body 2 in the vertical direction of the refill body 2 of the second embodiment and hangs down in a bowl shape downward. A portion 27 is formed.

  Here, the refill body 2 of the second embodiment is different from the first embodiment in the configuration (shape) of the flange portion 27. That is, the flange portion 27 provided in the refill body 2 of the second embodiment includes an annular plate member that extends horizontally so as to surround the entire periphery of the refill body 2 and a portion that hangs down in a bowl shape. Although it has, the combination position of a board member and a bowl-shaped part differs. That is, unlike the first embodiment, the second embodiment has a hook-like portion connected to the substantially center in the radial direction of the plate member.

  Specifically, the flange portion 27 of the second embodiment has the positioning portion 22 at a position at an angle of 180 ° with respect to the center of the refill body 2. The positioning portion 22 is formed so as to protrude outward in the same manner as in the first embodiment, and is allowed to move in the vertical direction by being inserted into the second slit 34 described above. The movement in the circumferential direction can be restricted while the refill body 2 can be aligned with a predetermined circumferential position of the container body 4.

On the other hand, the flange portion 27 at an angle of 90 ° with respect to the attachment position of the positioning portion 22 described above with respect to the center of the refill body 2 can be inserted into the first slit 33 described above. Standing pieces 28 are formed.
The standing piece 28 is a rectangular member that extends so as to intersect the container body 4 in the radial direction, and is capable of penetrating the first slit 33 in the radial direction from the radially inner side toward the radially outer side. Further, the upright piece 28 has a thickness of about three times the thickness along the radial direction of the first slit 33 described above, and even when inserted into the first slit 33, about 1/3 from the protruding end. This part protrudes from the outer peripheral surface of the container body 4 toward the radially outer side. That is, by pushing back the portion protruding radially outward from the outer peripheral surface of the container main body 4, the midway side in the longitudinal direction of the engagement tongue 14 is separated from the engagement protrusion 13 radially inward, and the refill body 2 and the container main body 4 is released (fixed by the fixing means 8).

  The engaging tongue 14 is a long member having a proximal end connected to the positioning portion 22 described above and a distal end connected to the upright piece 28. The engaging tongue portion 14 is curved and formed in a substantially arc shape so as to follow the outer peripheral surface of the refill body 2. Specifically, the engagement tongue portion 14 is formed so as to connect between the positioning portion 22 and the standing piece 28 adjacent to the positioning portion 22 in the counterclockwise direction when viewed from above. Yes. Further, the engaging tongue portion 14 is formed so as to gradually approach the outer diameter side from the proximal end side toward the distal end side, and is slightly distorted from an arc having the center of curvature at the center of the refill body 2. Yes.

If the engaging tongue 14 is formed in a slightly distorted arc shape in this way, the engaging tongue 14 can be pressed against the inner peripheral surface of the container body 4 in the vicinity of the upright piece 28, and the engaging tongue 14 It is possible to reliably engage the midway side in the longitudinal direction with the engagement protrusion 13.
Further, the engaging tongue portion 14 is formed in a narrow neck shape such that the distal end side is about half the thickness in the vertical direction with respect to the proximal end side. Specifically, with respect to the vertical length of the engagement tongue 14 on the proximal end side, the engagement tongue 14 on the distal end side removes the upper half of the vertical length on the proximal end side, It has a shape that leaves only half of it. If the distal end side of the engaging tongue portion 14 is formed into a narrow neck in this way, the distal end side of the engaging tongue portion 14 is likely to be elastically deformed, and the midway side in the longitudinal direction of the engaging tongue portion 14 is engaged with the engagement protrusion. 13 can be reliably engaged.

  As shown in FIG. 9, the refill lid 6 of the second embodiment is a member formed in a covered cylindrical shape as in the first embodiment. Specifically, the refill lid 6 of the second embodiment is also a member formed in a covered cylindrical shape like the container lid 5, and the outer diameter of the refill lid 6 is substantially equal to the outer diameter of the container body 4. ing. The refill lid 6 includes a disc-shaped blocking portion 29 provided along the horizontal direction, a short cylindrical refill outer wall portion 30 that hangs downward from the outer edge of the blocking portion 29, and a refill outer wall portion 30. Furthermore, it has a refill inner wall portion 31 that is suspended downward from the lower surface of the closing portion 29 on the inner peripheral side and is formed in a short cylindrical shape shorter than the refill outer wall portion 30.

And the refill lid | cover 6 of 2nd Embodiment also has the obstruction | occlusion part 29, the removal means 9, and the integration means 10 similarly to 1st Embodiment.
The closing part 29 is formed in a disk shape larger in diameter than the outer diameter of the used refill body 2U and the new refill body 2N, like the canopy part 24 of the container lid 5. Further, the length of the refill inner wall portion 31 in the vertical direction is about half that of the refill outer wall portion 30, and the second screw portion 12 is formed on the inner peripheral surface of the inner wall portion 26. Therefore, if the second screw portion 12 is screwed into the first screw portion 11, the opening of the refill body 2 can be covered with the closing portion 29.

The removal means 9 of the second embodiment is a member capable of releasing the engagement of the engagement tongue portion 14 with respect to the engagement protrusion 13 as in the first embodiment, and the inner peripheral surface of the refill outer wall portion 30 of the refill body 2. It is comprised from the cancellation | release piece 23 formed in this.
As shown in detail in FIGS. 12 and 13, the release piece 23 is a portion protruding from the inner peripheral surface of the refill outer wall portion 30 toward the inside in the diameter. The release piece 23 is formed over the entire length of the outer wall portion 25 from the upper end to the lower end. The release piece 23 is formed so that the cross section when cut in the horizontal direction has a trapezoidal shape. Therefore, when the refill lid 6 is rotated with respect to the refill body 2 to a predetermined rotation position, the release piece 23 described above moves to the position of the upright piece 28 in accordance with the rotation of the refill lid 6, and the upright piece. Since 28 is pushed back radially inward (in the releasing direction), the engaging tongue 14 moves radially inward and is disengaged from the engaging protrusion 13, and the fixing by the fixing means 8 is released.

Note that if the release piece 23 is formed in a trapezoidal cross section as described above, it is possible to reliably push back the protruding end of the standing piece 28 that protrudes to the outside of the diameter by the protruding end of the release piece 23 that is widely formed.
Since the refill body 2 thus released from the release by the release piece 23 is separated from the container 7 of the container body 4, it can be moved upward and can be removed from the container 7. Become.

  The integration means 10 of the second embodiment also accommodates the refill body 2 that has been disengaged and switched to the released state by the release piece 23 (removal means 9) described above together with the refill lid 6 as in the first embodiment. The refill body 2 is integrated with the refill lid 6 to be pulled out from the portion 7. The integration means 10 used in the refill set 1 of the second embodiment also integrates the refill lid 6 with the refill body 2 by screwing, and there is no difference from the first embodiment. Therefore, detailed explanation is omitted.

In the refilling procedure using the refill set 1 of the second embodiment described above, the engaging direction of the engaging tongue 14 is different from that of the first embodiment, and therefore refilling is performed according to the following procedure.
Although not shown in the figure, first, from the state of being elastically deformed radially inward, the engaging tongue portion 14 is brought close to the engaging protrusion 13 of the refill body 2 using the repulsive force toward the radially outer side. Then, the midway side in the longitudinal direction of the engaging tongue 14 is curved so as to be along the inner peripheral surface of the container body 4, and the engaging tongue 14 is in a position to be caught by the engaging protrusion 13 protruding radially inward. The upward movement of the engaging tongue portion 14 is regulated by the engaging protrusion 13, and the refill body 2 is engaged and fixed in the housing portion 7 without moving up and down.

On the other hand, an upright piece 28 is provided at the tip of the engaging tongue 14. The standing piece 28 penetrates the first slit 33, and the protruding end protrudes outward from the outer peripheral surface of the container body 4.
Here, when releasing the above-described engaging tongue 14 from the engaging protrusion 13, the refill lid 6 is attached to the container body 4 so that the upright piece 28 moves in the clockwise direction when viewed from above. Rotate against. Then, the release piece 23 comes into contact with the protruding end of the upright piece 28 and the upright piece 28 is pushed back radially inward, so that the engaging tongue 14 can be separated from the engaging projection 13 inward in the radial direction. Since the refill body 2 can be moved upward, the refill body 2 can be easily taken out from the housing portion 7.

If the refill set 1 of 2nd Embodiment mentioned above is used, the function for releasing the fixing means 8 and the used refill body 2U from the container main body 4 for the lid for the new refill body 2N used for protecting the contents are used. Since the refill lid 6 has a plurality of functions, the number of parts can be reduced, the processing cost can be reduced, and the structure can be simplified. Therefore, the refill body 2 containing the contents can be easily replaced while the structure is simple and the processing cost is low.
[Third Embodiment]
Next, the refill set 1 of 3rd Embodiment is demonstrated using drawing.

In the refill set 1 of the third embodiment, the fixing means 8 for fixing the refill body 2 to the container body 4 has a structure different from that of the first embodiment or the second embodiment described above, and therefore the refill body 2 is refilled. The refilling procedure is also very different from these embodiments.
In order to deepen the understanding of the present invention, the procedure for performing refilling using the refill set 1 as in the first embodiment will be described first with respect to the third embodiment.

  As shown in FIGS. 14 and 15, the refilling procedure of the third embodiment is to remove the used refill body 2 </ b> U from the container body 4 using the refill set 1. Then, a new cover 2N of the refill set 1 is attached to the container body 4 from which the used refill body 2U has been removed in this manner, and the container lid 5 that has been screwed into the used refill body 2U. And the removed container lid 5 is attached to the new refill body 2N of the container body 4. Obtaining the container 3 in which the new refill body 2N is replaced in accordance with the procedure as described above is a rough refill procedure of the third embodiment.

Each procedure will be described in more detail as follows.
That is, as shown in FIG. 14A, when refilling is performed using the refill set 1 of the third embodiment, the refill set 1 containing the new refill body 2N is prepared as in the first embodiment. This refill set 1 is a member shown on the lower side in FIG. 14 (a), and a new refill body for storing contents in a bottomed cylindrical shape made of synthetic resin as in the other embodiments. 2N and the refill lid | cover 6 which can block | close the opening of the upper part of this new refill body 2N are comprised.

  As shown in FIG. 14B, when the refill set 1 is prepared, the used refill body 2U is removed from the container body 4 using the prepared refill set 1 as it is (with the refill lid 6 attached). . In the first embodiment and the second embodiment, only the refill lid 6 is removed from the refill set 1 and the refill lid 6 is screwed to operate the removal means 9. In the third embodiment, the removal means 9 is operated. It is not necessary to remove the refill lid 6 in order to operate 9. This is because in the third embodiment, the release piece 23 of the removal means 9 does not act in accordance with the screwing operation of the refill lid 6, but the release piece 23 of the removal means 9 protruding upward from the upper surface of the refill lid 6. Is pushed into the engagement hole 35 of the container main body 4 from below and then rotated to remove the used refill body 2U. Therefore, in the third embodiment, the used refill body 2U is removed using the refill set 1 to which the refill lid 6 is attached as it is.

  Specifically, in the inside of the container main body 4 shown in FIG. 14B, an engagement hole 35 is formed on the bottom surface of the container main body 4 of the third embodiment so as to penetrate the bottom of the container main body 4 up and down. . The engagement hole 35 is engaged with the engagement tongue portion 14 of the refill body 2 inserted from above the engagement hole 35. When the above-described release piece 23 is inserted into the engagement hole 35 from below, the engagement of the engagement tongue 14 previously engaged is released, and the used refill body 2U from the container body 4 is released. Can be separated. Further, the bottom surface of the used refill body 2U separated from the container main body 4 has a pushed-up piece 40 protruding downward, and the container main body until the push-up protrusion 42 of the refill lid 6 contacts the pushed-up piece 40. When the refill set 1 is rotated with respect to 4, the used refill body 2U is pushed upward, and the used refill body 2U is lifted in the container body 4. Note that the structure and operation of the above-described members are not clearly shown in the drawing of FIG. These will be described in detail as each member is described later.

That is, when the engagement tongue 14 is disengaged by the release piece 23 and the container lid 5 is rotated with respect to the container body 4, the used refill body 2 </ b> U is lifted using the push-up protrusion 42, and the container 3 Can be separated into two parts.
In the above-described rotation, when viewed from above, the clockwise direction is a direction for engaging or fixing, and the counterclockwise direction is a direction for releasing engagement or fixing. This rotation direction is the same in any relationship between the refill body 2 and the container lid 5, the refill body 2 and the refill lid 6, and the refill lid 6 and the container body 4.

As shown in FIG. 14 (c), the container 3 separated into two is composed of an upper separation body 36 composed of a used refill body 2 U and a container lid 5, a container body 4 and a refill set 1. The separated member 37 is separated into two members.
Next, an operation procedure for one of the separated containers 3, that is, the upper separating body 36 indicated by (* 1) in FIG. 14 will be described.

As shown in FIG. 15 (d), the upper separator 36 is such that the container lid 5 is engaged with the used refill body 2U by screwing. Therefore, the container lid 5 can be removed from the upper separator 36 by rotating the container lid 5 in the direction opposite to that at the time of attachment.
As shown in FIG. 15E, when the container lid 5 is removed from the upper separator 36, only the used refill body 2U remains. Since the remaining used refill body 2U has used up the contents, it may be discarded as appropriate. Further, the removed container lid 5 is screwed into the refilled container body 4 and used again as the container 3 in the procedure shown in FIG.

In addition, an operation procedure for the other separated container 3, that is, the lower separated body 37 indicated by (* 2) in FIG. 14 will be described.
As shown in FIG. 15 (f), the lower separator 37 is composed of the container body 4 from which the used refill body 2 U has been removed from the storage portion 7 and the refill set 1. In the engagement hole 35, the release piece 23 of the refill set 1 is left inserted. However, since the release piece 23 is only inserted into the engagement hole 35, the refill set 1 can be easily separated from the container body 4 by pulling the refill set 1 downward.

As shown in FIG. 15 (g), the refill set 1 separated from the container body 4 includes a new refill. Therefore, next, the refill set 1 is moved above the accommodating portion 7 of the container body 4, the refill set 1 is inserted downward from above, and the new refill body 2 </ b> N together with the refill lid 6 is accommodated in the container body 4. Attach to part 7.
Specifically, as shown in FIG. 15 (h), the refill set 1 is inserted from above into the accommodating portion 7 of the container body 4 so that the new refill body 2N is at the bottom. The above-mentioned engagement tongue 14 is provided on the bottom of the refill body 2 of the third embodiment so as to protrude downward, and the engagement tongue 14 that was initially on the bottom of the container body 4 is provided. In addition, the engagement hole 35 exists in a state in which the release piece 23 is extracted and becomes empty. Therefore, when the engaging tongue portion 14 is inserted into the engaging hole 35 from above, the new refill body 2N can be mounted (fixed) together with the refill lid 6 in the accommodating portion 7 of the container body 4.

  That is, in the refill set 1 of the third embodiment, the engaging tongue 14 of the refill body 2 and the engaging hole 35 that engages with the engaging tongue 14 and is formed at the bottom of the container body 4 are The fixing means 8 which fixes the refill body 2 to the container main body 4 is comprised. Further, in the third embodiment, the release piece 23 provided on the upper surface of the refill lid 6 described above is the removal means 9 for removing the fixing means 8.

  As shown in FIG. 15 (h), when the refill set 1 is fixed to the container body 4 by the fixing means 8, only the refill lid 6 is removed from the refill set 1 as shown in FIG. 15 (i). Specifically, also in the third embodiment, the refill lid 6 is attached to the refill body 2 by screwing. Therefore, it is possible to remove only the refill lid 6 from the refill set 1 by rotating the refill lid 6 in a direction opposite to that at the time of attachment (counterclockwise as viewed from above). The refill lid 6 removed in this manner is appropriately discarded in the same manner as the used refill body 2U described above.

On the other hand, by removing the refill lid 6 from the refill set 1, the container lid 5 separated from the upper separation body 36 indicated by (* 1) described above is applied to the new refill body 2N remaining in the container body 4. Can be attached. By attaching the container lid 5 to the container body 4 in this manner, the container 3 as shown in FIG. 15 (j) is obtained.
The above is the refill procedure of the refill body 2 using the refill set 1 of the third embodiment.

Next, the refill set 1 of 3rd Embodiment is demonstrated using drawing.
The refill set 1 of 3rd Embodiment is also comprised from 2 members of the new refill body 2N and the refill lid | cover 6 similarly to 1st Embodiment or 2nd Embodiment.
However, in the first embodiment and the second embodiment, the engagement tongue portion 14 of the refill body 2 is engaged in the radial direction with respect to the engagement protrusions 13 projecting radially outward or radially inward, and the refill body 2 is It was fixed to the container 7 of the container body 4. However, in the refill set 1 of 3rd Embodiment, the engagement protrusion 13 is not provided in the container main body 4, but the engagement hole 35 is formed instead. Then, the refill body 2 is engaged (fixed) with the container body 4 by inserting the engagement tongue portion 14 downward into the engagement hole 35 of the container body 4.

Next, each member which comprises the refill set 1 of 3rd Embodiment is demonstrated.
First, the container body 4 constituting the container 3 of the third embodiment will be described.
As shown in FIG. 18, the container body 4 of the third embodiment is formed into a bottomed cylindrical shape using synthetic resin, metal, etc., as in the first embodiment and the second embodiment. It has the accommodating part 7 which can accommodate the used refill body 2U and the new refill body 2N. The container body 4 of the third embodiment is different from the other embodiments in the structure of the bottom side and the outer peripheral side due to the difference in the engaging direction.

That is, in the container body 4 of the third embodiment, the engagement tongue 14 and the engagement hole 35 of the refill body 2 are relatively moved along the vertical direction to engage and release. Therefore, the structure for fixing the refill body 2 is not provided at all on the outer peripheral side of the container body 4 as in the first embodiment or the second embodiment, and the outer peripheral side is formed in a simple shape. It has become.
Specifically, the upper end of the container body 4 is formed in an annular plane when viewed from above, and is stepped so that the inner corner is one step lower than the outer diameter, By fitting the lower end of the refill body 2 into the stepped portion, the refill body 2 can be attached in a sealed state.

  In addition, a positioning recess 38 is formed on the inner peripheral surface of the container body 4, in other words, on the outer peripheral surface of the accommodating portion 7. The positioning recesses 38 are respectively formed at two locations sandwiching the center of the container body 4 in the same manner as the vertical groove 18 of the first embodiment, and in the vertical direction with the positioning portions 22 formed on the outer peripheral surface of the refill body 2. It can be loosely fitted to be movable. If the positioning portion 22 of the refill body 2 is loosely fitted in the positioning recess 38 of the container body 4 as described above, the refill body 2 or the new refill body 2N can be inserted into a predetermined position in the circumferential direction of the housing portion 7. The engaging tongue 14 of the refill body 2 can be surely inserted into the engaging hole 35 of the container body 4 and engaged therewith.

  The engagement hole 35 is a hole formed in the bottom portion of the container body 4 so as to penetrate the bottom portion in the vertical direction, and allows both the engagement tongue portion 14 and the release piece 23 described later to be inserted. Thus, it is formed in a state that opens both upward and downward. The engagement hole 35 is a long hole formed in the bottom of the container body 4 so as to extend in the horizontal direction, and is formed in a shape that draws an arc shape with the center of the container body 4 as the rotation center when viewed from above. Has been.

The opening width (short width of the long hole) that crosses the engagement hole 35 along the radial direction is formed in an arc shape having a dimension that allows an engagement tongue 14 to be described later to be easily inserted along the vertical direction.
On the upper opening edge of the engagement hole 35, an engagement piece 21 protruding in a hook shape is formed.
The engagement piece 21 is a portion that protrudes in a bowl shape from the hole edge on the outer peripheral side of the engagement hole 35 toward the hole center side (inner peripheral side).
