  Hereinafter, with reference to FIGS. 1-4, the double container 1 which concerns on one Embodiment of this invention is illustrated and demonstrated in detail. In the present specification, the vertical direction means a direction along the center axis O of the inner container 10 and the outer container 20, and the upper side is the side where the opening 12 of the content container 11 of the inner container 10 is located. (For example, the upper side in FIG. 1) and the lower side mean the side (for example, the lower side in FIG. 1) on which the bottom wall portion 14 of the content container 11 is located.

  As shown in FIG. 1, the double container 1 according to the present embodiment includes an inner container 10 for refilling, an outer container 20, a pushing member 30, and an outer container cap 40.

  The inner container 10 includes a bottomed cylindrical content storage portion 11 centering on the axis O, and the content C is stored in the content storage portion 11. That is, the content accommodating part 11 forms the opening part 12 in the upper part, and has the surrounding wall part 13 and the bottom wall part 14 which were connected integrally. An annular outward convex portion 15 (engagement portion) is provided on the outer surface upper portion of the peripheral wall portion 13. In addition, an upper cylinder portion 16 that is larger in diameter than other portions of the peripheral wall portion 13 and disposed above the side wall member 23 of the outer container 20 is provided at the upper end portion of the peripheral wall portion 13.

  In addition, the inner container 10 is provided with an inclined surface 17 that connects the outer surface of the peripheral wall portion 13 and the outer surface (lower surface) of the bottom wall portion 14 and extends in an annular shape along the circumferential direction about the axis O. Yes. The inclined surface 17 is gradually reduced in diameter from the peripheral wall portion 13 toward the bottom wall portion 14, that is, downward. In the present embodiment, the contour line of the inclined surface 17 is linear in the cross section shown in FIG. 1A. However, the present invention is not limited to this, and the curved shape in which the contour line of the inclined surface 17 is curved. It is good.

  As shown in FIG. 1, the outer container 20 includes a bottomed cylindrical inner container storage portion 21 that stores the inner container 10. The inner container housing portion 21 includes a cylindrical side wall member 23 that forms an opening 22 at an upper portion thereof, and a bottom lid 24 that is mounted so as to close an opening on one end side (lower end side) of the side wall member 23. An external thread 25 is provided on the outer surface of the upper portion of the side wall member 23, and an inward convex portion 26 (engaged) that prevents the inner container 10 from coming out by engaging with the outward convex portion 15 undercut on the inner surface. Part). At the lower end of the side wall member 23, a fitting cylinder portion 27 that fits into the annular groove portion 24 a of the bottom lid 24 is provided. On the outer surface of the lower portion of the side wall member 23, there is provided a recess 28 into which a pressing portion 33 described later enters. The side wall member 23 is formed with a thin portion 29 by providing a recess 28, and the thin portion 29 has a groove 29 a (opening) formed in a notch shape from the lower end upward. Yes.

  As shown in FIGS. 1A and 1B, the push-in member 30 has an arm portion 31 via an arm portion 31 that is curved in an arc shape and a connecting portion 32 that extends radially outward from the center portion of the arm portion 31. And a pressing portion 33 connected to the. The arm portion 31 is disposed adjacent to the inclined surface 17 between the inner container 10 and the outer container 20. That is, the arm portion 31 extends along the circumferential direction around the axis O, and is disposed in a space surrounded by the inner surface of the side wall member 23, the inner surface (upper surface) of the bottom cover 24, and the inclined surface 17. . In the present embodiment, the arm portion 31 is configured to extend in a range slightly exceeding 180 ° in the circumferential direction around the axis O, but is not limited thereto, and is less than 180 °, for example, a range of about 90 °. It is also possible to have a configuration that extends to 180 °, a shape that extends significantly beyond 180 °, for example, in a range of about 270 °, or an annular shape that extends over the entire circumference. .

  The pressing portion 33 is fitted into a recess 28 provided on the outer surface of the lower side wall member 23. On the outer surface of the side wall member 23 around the recess 28, chamfered portions 28a are provided on the top, bottom, left and right. As a result, the finger that pushes the pressing portion 33 is not easily blocked by the outer surface of the side wall member 23 around the recess 28, and the pressing portion 33 is easily pushed.

  When attaching the pushing member 30 to the outer container 20, the bottom lid 24 is removed, and the connecting portion 32 is inserted into the groove 29 a from below so that the bottom lid 24 is attached. The pushing member 30 attached in this manner can move in the radial direction within a predetermined range with respect to the outer container 20. That is, the pushing member 30 is movable in the radial direction according to the difference between the distance between the arm portion 31 and the pressing portion 33 and the thickness of the thin portion 29 located between the arm portion 31 and the pressing portion 33. Yes. FIGS. 1A and 1B show an initial state where the pushing member 30 is located on the outermost radial direction within the movable range, and FIGS. 2A and 2B show the most diameter. The maximum pushing state located inside the direction is shown.

  In the initial state, the outer surface 33 a of the pressing portion 33 is exposed to the outside of the outer container 20, but the outer surface 33 a of the pressing portion 33 is located on substantially the same surface as the outer surface of the side wall member 23. For this reason, the overall shape is a columnar shape with little unevenness. Thereby, the external appearance with a sense of unity can be obtained and the aesthetics of the container can be enhanced.

  As shown in FIG. 1A, the outer container cap 40 includes a cylindrical outer wall portion 41 and a top wall portion 42 that closes the upper end portion of the outer wall portion 41. On the inner peripheral surface of the outer wall portion 41, a female screw 43 that is screwed with the male screw 25 described above is provided. A disc-shaped packing 44 is attached to the lower surface of the top wall portion 42, and the content container 11 is sealed by bringing the upper surface of the upper tube portion 16 of the inner container 10 into close contact with the packing 44. It has become so. In this embodiment, the packing 44 is assembled by sticking. However, the present invention is not limited to this, and a convex portion is provided on the inner peripheral surface of the outer wall portion 41 of the outer container cap 40 to get over the convex portion. As long as the packing 44 is assembled to such an extent that it does not fall off, the assembling method can be selected as appropriate.

  In the double container 1 having such a configuration, when the contents C are used up, the inner container 10 can be replaced with a new inner container 10 in the following manner. That is, first, the outer container cap 40 is removed from the state shown in FIG. Next, as shown by the arrow in FIG. 1B, when the outer surface 33 a of the pressing portion 33 of the pressing member 30 is pushed inward in the radial direction of the outer container 20, the arm portion 31 is moved in the radial direction via the connecting portion 32. It is pushed inward. When the arm portion 31 moves radially inward, the arm portion 31 comes into contact with the inclined surface 17 and the inclined surface 17 is pressed radially inward. The inner container 10 is surrounded by the side wall member 23 of the outer container 20 and the relative displacement in the horizontal direction is restricted. A part of the radially inward force applied to the inclined surface 17 is caused by the inclined surface 17. It is converted into an upward force. For this reason, when the arm portion 31 moves radially inward while sliding with respect to the inclined surface 17, the inner container 10 is pushed upward. During this time, the arm portion 31 is supported from below by the inner surface (upper surface) of the bottom cover 24. Then, as shown in FIG. 2A, the upper cylindrical portion 16 of the inner container 10 pushed upward can be grasped and pulled upward to be taken out, and the used inner container 10 can be discarded as it is. .

  Next, a method for attaching the new inner container 10 to the outer container 20 will be described. In the refill inner container 10, for example, when not in use, the opening 12 is closed by attaching a cap member or a seal member, and the quality of the content C such as cream is maintained. Thus, the cap member and the seal member can be removed when attaching to the outer container 20.

  When the new inner container 10 is attached to the outer container 20, the inclined surface 17 is moved to the arm portion by inserting and pushing the new inner container 10 into the inner container storage portion 21 of the outer container 20 from the bottom wall portion 14 side. The arm portion 31 is moved downward while abutting 31 and pushing the arm portion 31 radially outward. When the inner container 10 is pushed in until the lower surface of the upper cylindrical portion 16 of the new inner container 10 comes into contact with the upper surface of the side wall member 23, the pushing member 30 automatically reaches the initial position shown in FIGS. 1 (a) and 1 (b). Thus, the replacement of the inner container 10 is completed.

  As described above, in the double container 1 according to the present embodiment, when replacing the inner container 10, the inner container 10 is moved to the outer container only by pushing the outer surface 33 a of the pressing portion 33 exposed on the outer surface of the outer container 20. It can be pushed upward from 20 to a certain range. As a result, the inner container 10 can be easily removed with a relatively small force and without a complicated operation. Further, since the new inner container 10 can be attached only by pushing the inner container 10 into the inner container storage portion 21 of the outer container 20, the attaching operation is also easy.

  In this embodiment, in the process of pushing the pressing portion 33 from the initial state shown in FIGS. 1A and 1B to the maximum pushing state shown in FIGS. And the inward projection 26 are disengaged. Thereby, after the pressing portion 33 is pushed down to the maximum pushing state shown in FIGS. 2A and 2B, the engagement between the outward convex portion 15 and the inward convex portion 26 is released. If the part 16 is gripped and pulled upward, the inner container 10 can be easily taken out with a light force. Further, in the process of pushing the new inner container 10 into the inner container storage part 21 of the outer container 20, the outward convex part 15 and the inward convex part 26 get over each other and are fitted to prevent the inner container 10 from coming out. Yes. Thereby, it is possible to prevent the inner container 10 from dropping off in a state where the outer container cap 40 is removed (the state shown in FIG. 3B).

  Further, in the present embodiment, the outer shape of the inner container 10 is a bottomed cylindrical shape that is uniform in the circumferential direction. Thereby, when inserting the inner container 10 in the outer container 20, it is not necessary to confirm and align the positions in the circumferential direction, so that the attachment is further facilitated.

  Moreover, in this embodiment, the width of the pressing part 33 and the arm part 31 is made larger than the groove width of the groove part 29a so that the pressing part 33 and the arm part 31 cannot pass through the groove part 29a in the radial direction. Therefore, as long as the bottom cover 24 is not removed, there is no possibility that the push-in member 30 falls off the outer container 20. Further, when the pressing portion 33 is pushed inward in the radial direction, the pressing portion 33 comes into contact with the thin portion 29 and further pressing is restricted, so that the pressing portion 33 is pushed too much and it is difficult to return to the original position. There is no fear of becoming.

  Moreover, in this embodiment, the arm part 31 surrounds the inclined surface 17 of the inner container 10 over the range of 180 degree | times or more along the circumferential direction. Thereby, the pressing force from the arm part 31 can be transmitted to the inclined surface 17 over a wide range in the circumferential direction, and the inner container 10 can be easily pushed up with a smaller force. In addition, the arm part 31 can also be made into the annular | circular shape which surrounds the inner container 10 over a perimeter. In this case, by pushing the pressing portion 33 inward in the radial direction, the arm portion 31 is elastically deformed so that the circular shape is distorted in a plan view, and when the pressing force to the pressing portion 33 is released, the restoring force of the arm portion 31 The arm part 31 returns to the original shape, and as a result, the pressing part 33 also returns to the original position.

  3 and 4 show a second embodiment of the present invention. Note that portions having the same basic functions as those of the above-described embodiment are denoted by the same reference numerals in the drawing and description thereof is omitted.

  As shown in FIGS. 3A and 3B, in the double container 100 of the present embodiment, the inner container storage part 121 of the outer container 120 includes a cylindrical part 123 that constitutes a side wall, and the cylindrical part 123. And a bottom wall portion 124 integrally connected to the main body. A through hole 123 a (opening) that penetrates the tubular portion 123 is formed in the lower portion of the tubular portion 123. Further, the tubular portion 123 is provided with a bulging portion 123b that bulges radially inward from the inner surface of the tubular portion 123 at the lower portion of the inner surface in the direction facing the through hole 123a.

  The push-in member 130 includes a pair of arm portions 131 that are curved in an arc shape, a pair of connecting portions 132 that extend radially outward from respective one end portions of the pair of arm portions 131, and a pressing portion 133 that connects the pair of connecting portions 132. And have. The extension range in the circumferential direction of the pair of arm portions 131 is a range slightly exceeding 180 ° with the axis O as the center, similar to the arm portion 31 of the first embodiment, but is limited to this. is not. Further, in the initial state shown in FIG. 3B, a bulging portion 123b is provided at a circumferential position excluding the extending range of the arm portion 131, and the tip 131a of the arm portion 131 has a bulging portion 123b. It is arranged in proximity to the tip 123c. The tip 123c of the bulging portion 123b is provided with an inclined surface 123d formed so as to gradually increase in diameter toward the tip 131a of the arm portion 131. Accordingly, when the pressing portion 133 is pushed inward in the radial direction, the tip 131a of the arm portion 131 can smoothly move inward in the radial direction of the bulging portion 123b.

  When attaching the pushing member 130 of the present embodiment to the outer container 120, with the inner container 10 removed, the pair of arm parts 131 are elastically deformed radially inward and inserted into the inner container storage part 121, The pressing part 133 is arranged so as to be inserted into the through hole 123a.

  When replacing the inner container 10 from the initial state shown in FIGS. 3A and 3B, first, the outer container cap 40 is rotated and removed in the screwing direction. Next, as shown by the arrow in FIG. 3B, the outer surface 133 a of the pressing portion 133 of the pressing member 130 is pressed toward the radially inner side of the outer container 120. As a result, the arm portion 131 is pushed inward in the radial direction via the pair of connecting portions 132 and slides with respect to the inclined surface 17, and the inner container 10 is pushed upward. In the present embodiment, when the arm portion 131 is pushed inward in the radial direction, the distal end 131a of the arm portion 131 rides on the distal end 123c of the bulging portion 123b and moves to the radially inner side of the bulging portion 123b. . Thereby, it becomes easy to move to radial inside over the whole area | region of the circumferential direction including the front-end | tip 131a of the arm part 131, and it can press the inclined surface 17 over the wider range of the circumferential direction. Thereby, the inner container 10 can be pushed up more easily.

  When the pressing portion 133 is pushed down to the maximum pushing state shown in FIGS. 4A and 4B, the engagement between the outward projecting portion 15 and the inward projecting portion 26 is released. The used inner container 10 can be discarded as it is pulled up. When the new inner container 10 is attached to the outer container 120, the pushing member 130 is simply inserted and pushed into the inner container housing portion 121 as in the first embodiment. The position automatically returns to the initial position shown in (a) and (b), and the replacement of the inner container 10 is completed.

  In the double container 100 according to the present embodiment, the cylindrical portion 123 and the bottom wall portion 124 of the outer container 120 are integrally connected to form one component. Can be reduced.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, the peripheral wall portion 13 of the inner container 10 and the side wall member 23 of the outer container 20 are not limited to a cylindrical shape, and may have an elliptical shape or other shapes. Moreover, you may provide the structure of the bulging part 123b of 2nd Embodiment in the inner surface of the side wall member 23 of the outer container 20 of 1st Embodiment. In the previous embodiment, the outer containers 20 and 120 and the outer container cap 40 are configured to be screw-engaged. However, the present invention is not limited to this, and a configuration in which the undercut engagement is detachable is also possible. .
