Summary of the Invention

Problems to be Solved by the Invention

[0004] The container of Patent Document 1 has the inconvenience that it cannot be refilled after the contents are used up and must be disposable.

[0005] An object of the present invention is to provide an aerosol container capable of refilling the contents.

Means for Solving the Problems

[0006] The first means includes a container body 2 having a neck portion 10 standing up from a body portion 8, an injector 80 detachably attached to the neck portion 10, a sliding member 12 having a sliding partition wall 13 vertically inserted into the body portion 8 so as to be movable up and down between a lower limit height T and an upper limit height U in an upwardly biased state, and a hanging cylinder 15 hanging down from the sliding partition wall 13, and an operating mechanism A for operating to pull back the sliding partition wall 13 that has reached the upper limit height U to the lower limit height T as the contents are ejected from the injector 80. The operating mechanism A includes an operating rod 72 vertically inserted into the hanging cylinder 15 so as to be movable up and down, A shaft portion 26 rotatably inserted between the hanging cylinder 15 and the operating rod 72, and a movable portion 52 assembled so as to rotate together with the shaft portion 26 and arranged to be retractable between an outer position О and an inner position I in the radial direction of the hanging cylinder 15 by the lifting and lowering of the operating rod 72. A first interlocking means L1 for raising and lowering the hanging cylinder 15 in conjunction with the rotation of the shaft portion 26 is provided between the movable portion 52 and the hanging cylinder 15.

[0007] As shown in FIG. 1, the aerosol container of this means has a hanging cylinder 15 vertically provided from a sliding partition wall 13 fitted in an upwardly biased state in the body portion 8 of the container body 2, and has an operating mechanism A for pulling back the sliding partition wall 13 that has reached the upper limit height U to the lower limit height T as shown by the imaginary line in FIG. 4(A). According to this structure, the injector 80 can be removed from the mouth-neck portion 10, and the contents can be refilled from the mouth-neck portion 10 with the sliding partition wall 13 pulled back to the lower limit height T, which is convenient to use. The operating mechanism A has an operating rod 72 inserted into the hanging cylinder 15 so as to be movable up and down, and a movable portion 52 assembled to a shaft portion 26 inserted between the operating rod 72 and the hanging cylinder 15. This movable portion 52 moves back and forth between the outer position О shown in FIG. 1 and the inner position I shown in FIG. 3(A) by the lifting and lowering of the operating rod 72, and the hanging cylinder 15 is lifted and lowered in conjunction with the rotation of the shaft portion 26 by the action of the first interlocking means L1 between the movable portion 52 and the hanging cylinder 15. According to this structure, the operation of pulling back the sliding partition wall 13 only requires rotating the shaft portion 26 after raising the operating rod 72, so the operation is simple.

[0008] The second means has the first means, and the first interlocking means L1 is formed by a screw groove 16 formed on the inner surface of the hanging cylinder 15 and a sliding projection 56 attached to the outer surface of the movable portion 52 and screwed into the screw groove 16 when the movable portion 52 advances to the outer position О.

[0009] In this means, as shown in FIG. 1, the first interlocking means L1 is composed of a screw groove 16 formed on the inner surface of the hanging cylinder 15 and a sliding protrusion 56 attached to the outer surface of the movable part 52. When the movable part 52 advances to the outer position O, the sliding protrusion 56 is screwed into the screw groove 16. According to this structure, the sliding partition 13 can be stably pulled back to the lower limit height T.

[0010] The third means has the second means, and the shaft portion 26 has a contact portion 32 for contacting the upper end surface 73 of the operating rod 72 in the rising state. The sliding protrusion 56 is formed to be inserted into the screw groove 16 in the contact state between the upper end surface 73 of the operating rod 72 and the contact portion 32, and a positioning means Q for positioning the operating rod 72 at the contact position with the contact portion 32 is provided between the contact portion 32 and the operating rod 72.

[0011] In this means, as shown in FIG. 1, the upper end surface 73 of the operating rod 72 is brought into contact with the contact portion 32 of the shaft portion 26, and the sliding protrusion 56 is formed to be inserted into the screw groove 16 in the contact state between the upper end surface 73 of the operating rod 72 and the contact portion 32. And a positioning means Q for positioning the operating rod 72 at the contact position with the contact portion 32 is provided between the contact portion 32 and the operating rod 72. According to this structure, it is possible to prevent the operating rod 72 from unexpectedly shifting from the contact state with the contact portion 32. Therefore, the screwed state between the screw groove and the sliding protrusion can be appropriately maintained.

[0012] The fourth means has any one of the first means to the third means, and between the movable part 52 and the operating rod 72, there is a cam means composed of a cam shaft 76 attached to one of the opposing surfaces of the movable part 52 and the operating rod 72 and a cam hole 62 recessed in the other surface, and a second interlocking means L2 is provided which is formed to advance and retreat the movable part 52 in conjunction with the raising and lowering of the operating rod 72.

[0013] In this means, as shown in FIG. 2(B), the second interlocking means L2 for interlocking the raising and lowering of the operating rod 72 with the advancing and retreating of the movable part 52 is realized by a cam. According to this structure, the movable part 52 can move smoothly in response to the raising and lowering of the operating rod 72. Alternatively, the fine movement such as the entry and departure of the sliding protrusion 56 into and from the screw groove 16 can also be accurately realized by the raising and lowering operation of the operating rod 72. Therefore, the operability is improved.

[0014] The fifth means has the fourth means, and the shaft portion 26 is composed of a plurality of shaft rods 28 arranged around the operating rod 72 when viewed from above, and the movable parts 52 are respectively provided between the adjacent shaft rods 28, so that the plurality of shaft rods 28 and the plurality of movable parts 52 are alternately arranged so as to surround the operating rod 72.

[0015] In this means, as shown in Fig. 3(C), the shaft portion 26 is composed of a plurality of shaft rods 28 arranged around the operating rod 72 when viewed from above, and the movable parts 52 are respectively provided between the adjacent shaft rods 28. According to this structure, the sliding partition 13 can be stably pulled down by screwing the plurality of sliding protrusions 56. In addition, the plurality of shaft rods 28 and the plurality of movable parts 52 are arranged so as to alternately surround the operating rod 72 when viewed from above. According to this structure, the force can be transmitted from one operating rod 72 to the plurality of movable parts 52 without difficulty using the cam means.

Effect of the Invention

[0016] According to the present invention, after the contents of the aerosol container are used up, it is possible to refill the contents.

Best Mode for Carrying Out the Invention

[0018] FIGS. 1 to 4 show an aerosol container according to an embodiment of the present invention. This aerosol container includes a container body 2, a sliding member 12, an operating member 18, and an injector 80. These members can be formed of, for example, synthetic resin or metal.

[0019] The container body 2 is a member having a neck portion 10 standing up from a body portion 8, and a bottom portion 3 having a lower opening 6 is attached to the body portion 8. In the present embodiment, the container body 2 is formed of two parts, a bottom member 3 which is the bottom part and a container body main body 7. However, this structure can be appropriately changed.

[0020] The bottom member 3 is formed by extending a cylindrical peripheral wall portion 5 from the peripheral edge of a circumferential bottom plate 4 as seen from above, and the lower opening 6 is formed inside the bottom plate 4. This lower opening 6 is circular as seen from above and is formed so that a shaft cylinder portion 25 described later can be rotatably fitted therein. In addition, a pressure contact rib j for biting into the body portion 8 described later is attached to the inner surface of the peripheral wall portion 5. And, by making the upper half of the inner peripheral surface of the bottom plate 4 (the mouth surface of the lower opening 6) have a larger diameter than its lower half, a holding recess d for fitting the lower end portion of a coil spring (first biasing means C1) described later is formed.

[0021] The container body 7 has a neck portion 10 erected from a cylindrical portion 8 with an open lower end via a shoulder portion 9. A male screw portion 11 is formed on this neck portion 10. The cylindrical portion 8 is a vertically long straight cylinder. The lower half of this cylindrical portion 8 is fitted inside the peripheral wall portion 5 of the bottom member 3.

[0022] The sliding member 12 has a sliding partition wall 13 that is fitted into the cylindrical portion 8 in an upwardly biased state so as to be able to move up and down between a lower limit height T and an upper limit height U shown in FIG. 1, and a cylindrical hanging cylinder 15 is vertically provided from this sliding partition wall 13. The sliding partition wall 13 is a middle plate that serves to partition the inside of the cylindrical portion 8 into a liquid storage chamber and a storage chamber for the operating member 18. A cylindrical piston 14 that slides on the inner surface of the cylindrical portion 8 is formed on the peripheral end side of the sliding partition wall 13. The sliding member 12 is biased upward by a first biasing means C1. In the illustrated example, a coil spring, which is the first biasing means C1, is interposed between the sliding partition wall 13 and the bottom plate 4 by being positioned outside the hanging cylinder 15. A screw groove 16 defined by a thread 17 is formed on the inner surface of the hanging cylinder 15. In the illustrated example, the pitch of the thread 17 is designed such that there is a gap g between the thread and the sliding projection 56 when the sliding projection 56 described later is inserted into the screw groove 16.

[0023] The operating member 18 has a function of pulling back the sliding partition wall 13 that has reached the upper limit height U to the lower limit height T as the content is ejected from the injector 80. And in this specification, the mechanism for realizing this function is referred to as an "operating mechanism". The operating mechanism A is composed of a shaft portion 26, a movable portion 52, and an operating rod 72, which will be described later. In the present embodiment, the operating member 18 is composed of a main operating body 20, a transmission body 50, and a sub-operating body 70.

[0024] The main operating body 20 is a part for performing a rotation operation around a vertical rotation axis (the cylinder axis of the hanging cylinder 15). This main operating body 20 is rotatably attached to the bottom 3 of the container body 2 from below. The main operating body 20 of this embodiment is formed by a leg cylinder 22 and a shaft portion 26.

[0025] In the illustrated example, the leg cylinder 22 is formed by erecting a shaft cylinder portion 25 from the upper end of the gripping cylinder portion 23 via an inward flange 24. And with the inward flange 24 in contact with the lower surface of the bottom plate 4, the shaft cylinder portion 25 is rotatably fitted into the lower opening 6. In the illustrated example, the outer peripheral surface of the gripping cylinder portion 23 and the outer peripheral surface of the bottom member 3 are flush.

[0026] An operating rod 72 is inserted into the shaft cylinder portion 25. In this embodiment, a cylindrical spacer 40 is inserted between the inner surface of the shaft cylinder portion 25 and the operating rod 72. By providing this cylindrical spacer 40, the assembly of the operating rod 72 can be performed accurately. As shown in FIG. 2(D), an insertion groove 42 for inserting a later-described linking projection 76 attached to the operating rod 72 is formed on the inner peripheral surface of the cylindrical spacer 40. And at a portion other than the portion where the insertion groove 42 is formed, the inner peripheral surface of the cylindrical spacer 40 is fitted to the outer peripheral surface of the operating rod 72. By doing so, in the state of FIG. 1, the lower end portion of the operating rod 72 is held without lateral movement. In this embodiment, as shown in FIG. 2(D), an outer rotation stopper r1 is provided between the inner peripheral surface of the shaft cylinder portion 25 and the outer peripheral surface of the cylindrical spacer 40, and an inner rotation stopper r2 is provided between the inner peripheral surface of the cylindrical spacer 40 and the outer peripheral surface of the operating rod 72. By doing so, the operating rod 72 is configured to be able to move up and down without rotation with respect to the leg cylinder 22. Specifically, by forming the inner peripheral surface of the shaft cylinder portion 25 and the outer peripheral surface of the cylindrical spacer 40 into a non-circular shape with a part being flat when viewed from above, and also forming the inner peripheral surface of the cylindrical spacer 40 and the outer peripheral surface of the operating rod 72 into a polygonal shape (a quadrilateral in the illustrated example), the flat portion is used as a rotation stopper. In the illustrated example, a claw receiving portion m for fitting a locking piece n protruding from the cylindrical spacer 40 is formed near the lower end of the shaft cylinder portion 25. On the inner surface of the shaft cylinder portion 25, a pressure contact rib k for pressing against the cylindrical spacer 40 is formed, and on the outer surface of the shaft cylinder portion 25, an annular recess e for locking to the base plate 4 below the aforementioned holding recess d is formed.

[0027] The shaft portion 26 is a member rotatably inserted between the hanging cylinder 15 and the operating rod 72, and while holding the posture of the movable portion 52 described later, as shown in FIG. 3(C), it has a role of guiding the advance and retreat of the movable portion 52 in the radial direction of the hanging cylinder 15. In this specification, for convenience of explanation, the direction in which the movable portion 52 advances and retreats in the horizontal direction is referred to as the first direction X, and the direction orthogonal to this is referred to as the second direction Y. The shaft portion 26 of the present embodiment includes a pair of shaft rods 28 erected from the leg cylinder 22 and a contact portion 32 connected to the upper end portions of these shaft rods 28. The pair of shaft rods 28 face each other with a gap in the second direction Y, and are arranged so that the operating rod 72 can be accommodated between these shaft rods 28. The shaft rod 28 in the illustrated example is formed in a vertically long plate shape having a certain width in the first direction X. And the opposing surfaces (inner surfaces) of the pair of shaft rods 28 are guide surfaces 30 for guiding the advance and retreat of the movable portion 52 in the first direction X, and are formed as flat surfaces parallel and perpendicular to each other. However, the structure of the shaft portion 26, for example, the number and shape of the shaft rods 28, can be appropriately changed according to design conditions (such as the number of movable portions 52, etc.).

[0028] The contact portion 32 is a portion for contacting the upper end surface 73 of the operating rod 72 in the raised state. In the present embodiment, the contact portion 32 is a flat horizontal plate-shaped (disc-shaped in the illustrated example) contact plate, and in the initial state shown in FIG. 1, it is arranged close to the sliding partition wall 13. The shape and arrangement of these contact portions 32 can be appropriately changed. Positioning means Q for positioning the operating rod 72 at the contact position with the contact portion 32 is provided between the contact portion 32 and the operating rod 72. In this specification, "positioning" means preventing the operating rod 72 from unexpectedly shifting (falling) from the contact position with the contact portion 32 and maintaining the contact state. Since it is to prevent "unexpectedly" shifting, as shown in Fig. 4(A), it is allowed for the locking convex portion 74 to shift inside the locking hole 34 by the operation of the sub-operating body 70. In the illustrated example, the positioning means Q is formed by a later-described locking convex portion 74 and a locking hole 34 into which the locking convex portion 74 can be detachably fitted (for example, press-fitted). By the action of this positioning means Q, for example, from the state of Fig. 1, it is possible to prevent or reduce the possibility that the upper end surface 73 of the operating rod 72 detaches from the contact portion 32 due to the self-weight of the operating rod 72 or an external force such as a collision with other objects. Therefore, it is possible to prevent the movable portion 52 from shifting unnecessarily to the inner position I side and releasing or making incomplete the screwed state of the sliding projection 56 and the screw groove 16.

[0029] The transmission body 50 is a member assembled to be rotatable together with the shaft portion 26. And the transmission body 50 includes a plurality of movable portions 52 that can advance and retreat between an outer position O in contact with the hanging cylinder 15 and an inner position I away from the hanging cylinder 15, and has a role of transmitting the rotational force with respect to the shaft portion 26 to a later-described first interlocking means L1 disposed between the movable portion 52 and the hanging cylinder 15.

[0030] In the present embodiment, as shown in Fig. 2(C), the movable portion 52 is disposed between a plurality of shaft rods 28 arranged around the operating rod 72 when viewed from above. By doing so, the plurality of shaft rods 28 and the plurality of movable portions 52 are arranged so as to alternately surround the operating rod 72. According to this structure, force can be transmitted from a single operating rod 72 to a plurality of movable portions 52 without difficulty using cam means. As shown in Fig. 2(B), the illustrated movable part 52 is formed to be vertically long to the same extent as the shaft rod 28. However, this form and length can be changed as appropriate. In this embodiment, a pair of movable parts 52 are provided, but the number of movable parts 52 can be changed as appropriate. These pair of movable parts 52 are sandwiched between the guide surfaces 30 of the two shaft rods 28, and are provided so as to be able to advance and retreat in the first direction X along these guide surfaces 30. Each movable part 52 is assembled to the shaft part 26 so as not to separate from the position along the guide surface 30. By doing so, the pair of movable parts 52 are provided so as to rotate together with the shaft part 26. Note that "assembled to the shaft part" includes a structure in which the movable part 52 is attached to the shaft part 26 via the operating rod 72. In this embodiment, the movable part 52 is linked to the operating rod 72 by the fitting of a linking projection 76 described later and a receiving hole 62 described later, and both ends in the longitudinal direction of this operating rod 72 are attached to the aforementioned contact part 32 and the cylindrical spacer 40 so as to be able to move up and down, and thus is indirectly assembled to the shaft part 26. In the illustrated example, as shown in Fig. 2(C), the movable part 52 is a long member having a substantially L-shaped cross section. And this movable part 52, when viewed from above, includes a wide and thick plate part (sliding arm part 53) in the second direction Y across between the pair of guide surfaces 30, and a thin plate part (linking strip 60) projecting in the first direction X from this thick plate part along one of the guide surfaces 30. These sliding arm part 53 and linking strip 60 both extend vertically across between the contact part 32 and the cylindrical spacer 40 in Fig. 2(B). The sliding arm part 53 is a part for slidingly contacting the hanging cylinder 15 in a state where the movable part 52 has advanced to the outer position O, and the linking strip 60 is a part where the receiving hole 62 is opened. By loosely fitting a linking projection 76 of an operating rod 72 described later into this receiving hole 62, the movable part 52 is linked to the operating rod 72. In the illustrated example, the outer surface 54 of the sliding arm part 53 is formed into an arcuate curved surface when viewed from above, and the inner surface 58 of the sliding arm part 53 is formed into a flat surface.

[0031] In this embodiment, the engaging projection 76 serves as a camshaft, and the receiving hole 62 serves as a cam hole. And a second interlocking means L2 is configured such that the movable portion 52 is advanced and retracted toward the hanging cylinder 15 side in conjunction with the lifting and lowering of the operating rod 72 by cam means including the camshaft 76 and the cam hole 62. To ensure this role, the receiving hole 62 has a lower inclined side 62L that receives a downward thrust force F indicated by an arrow in FIG. 2(B) from the engaging projection 76, and an upper inclined side 62U that receives an upward thrust force F indicated by an arrow in FIG. 3(B). And by replacing the thrust forces in the vertical direction received by these sides with lateral forces in the first direction X, the movable portion 52 is configured to be able to advance and retract between the outer position O and the inner position I. In the illustrated example, as shown in FIG. 2(B), the receiving hole 62 is formed in a substantially parallelogram shape defined by two vertical side edges, a lower inclined side 62L, and an upper inclined side 62U. If the vertical width of this receiving hole 62 is h2 and the vertical width of the engaging projection 76 is h1, the difference Δh (= h2 - h1) between them corresponds to the lifting and lowering range of the sub-operating body 70. The lifting and lowering range of the sub-operating body 70 is designed such that the locking projection 74 does not fall off from the locking hole 34 of the contact portion 32 when the sub-operating body 70 is pulled down as shown in FIG. 4. That is, as in the illustrated example, if the sliding allowance of the locking projection 74 shown in FIG. 1 is h3, then h3 > Δh. Note that the sliding allowance is the length that the locking projection 74 can slide in the locking hole 34, and in the illustrated example, it is equal to the protruding length of the locking projection 74. Also, in the illustrated example, three cam holes 62 are provided at intervals in the longitudinal direction of the connecting strip 60. However, these structures, for example, the arrangement and number of the camshaft 76 and the cam hole 62, can be changed as appropriate.

[0032] Also, a sliding protrusion 56 that engages with the screw groove 16 is formed on the outer surface of the sliding arm portion 53. In this specification, "threaded engagement" means a state in which the sliding protrusion 56 is inserted into the thread groove 16, and the hanging cylinder 15 can be screwed upward by rotating the shaft portion 26 in the forward direction and screwed downward by rotating it in the reverse direction. The above-described thread groove 16 and sliding protrusion 56 form a first interlocking means L1 for raising and lowering the hanging cylinder 15 in conjunction with the rotation of the shaft portion 26. This sliding protrusion 56 engages with the thread groove 16 when the movable portion 52 advances to the outer position O, and disengages from the thread groove 16 when it retracts to the inner position I. The sliding protrusion 56 may have any structure as long as it contributes to the function of engaging with the thread groove 16 to lower the hanging cylinder 15 from the upper limit height U to the lower limit height T. In this embodiment, a partial thread corresponding to the thread groove 16 is formed as the sliding protrusion 56. In this specification, "partial thread" refers to a structure that forms a part of the circumferential direction of a male thread.

[0033] The sub-operation body 70 is a part for performing a raising and lowering operation. In this embodiment, a gripping portion 78 is attached to the lower end of a vertically oriented operation rod 72. The operation rod 72 is rotatably supported inside the hanging cylinder 15 along its cylinder axis together with the main operation body 20. In this embodiment, as a supporting means for the operation rod 72, the locking hole 34 that supports the upper end side of the operation rod 72 and the above-described cylindrical spacer 40 that supports the lower end side of the operation rod 72 are provided. That is, the upper end surface 73 of the operation rod 72 is brought into contact with the contact portion 32 of the main operation body 20 described above, and a locking convex portion 74 protrudes upward from this upper end surface 73 and is rotatably fitted into the locking hole 34. Also, the operation rod 72 in the illustrated example is formed as a square bar-shaped pin, and the lower end portion of the operation rod 72 is fitted into the inner peripheral surface of the cylindrical spacer 40. A pair of linking protrusions 76, which are cam shafts, protrude outward from the opposite side surfaces of the square bar-shaped operation rod 72 and are loosely fitted into a receiving hole 62, which is a cam hole. The engaging projection 76 in the illustrated example is formed in an oval shape that is long in the vertical direction when viewed from the protruding direction. However, this shape can be changed as appropriate. The gripping portion 78 is connected to the lower end of the operating rod 72 and is disposed within the gripping cylinder portion 23. By gripping and vertically moving the gripping portion 78, the operating rod 72 can be raised and lowered.

[0034] The locking convex portion 74 in the illustrated example is formed in a boss shape (or short column shape), and by fitting this locking convex portion 74 into the locking hole 34, it is provided to prevent the operating rod 72 from shifting. As described above, the locking convex portion 74 is formed so as not to disengage from the locking hole 34 even in the pulled-down state of the sub-operating body 70 shown in FIG. 4(A). And it is formed such that the sliding projection 56 is inserted into the spiral groove 16 in the contact state between the upper end surface 73 of the operating rod 72 and the contact portion 32.

[0035] The injector 80 is detachably attached to the mouth-neck portion 10 of the container body 2. And after using up the contents, it is formed so that it can be removed from the mouth-neck portion 10 and the contents can be refilled. As long as it can be removed, the injector 80 can be of any type. In the illustrated example, the injector 80 supports a vertically oriented and hollow stem 88 that can move up and down in an upwardly biased state inside a mounting member 82 attached to the mouth-neck portion 10, and a push-down head 92 is attached to the upper end of this stem 88. As shown in FIG. 1, the mounting member 82 erects a guide cylinder portion 87 that guides the up and down movement of the stem 88 from the upper end of a mounting cylinder portion 84 screwed onto the outer surface of the mouth-neck portion 10 via an inward flange-shaped wall portion 86. In the same figure, reference symbol P indicates a packing sandwiched between the mouth-neck portion 10 and the inward flange 86. A female screw portion 85 that engages with the male screw portion 11 is formed on the mounting cylinder portion 84. The stem 88 closes the lower end opening of a vertical cylinder portion 90 inserted into the guide cylinder portion 87 with a closing plate portion 89, and has a horizontal communication hole 91 that communicates with the container body 2 at the lower part of the vertical cylinder portion 90. The pressing-down head 92 is fitted to the upper end of the stem 88 and has injection holes 93. A coil spring, which is the second biasing means C2, is interposed between the pressing-down head 92 and the flange-shaped wall portion 86. In the illustrated example, an overcap 94 is fitted to the outer surface of the mounting cylinder portion 84.

[0036] In the above configuration, when using the aerosol container, from the state of FIG. 1, the overcap 94 is removed, and the body portion 8 of the container body 2 is gripped and the gripping portion 78 is pulled downward. Then, the engaging projection 76 of the operating rod 72 comes into pressure contact with the lower inclined side 62L as shown in FIG. 2(B), so that the cam means (second interlocking means L2) acts, and in conjunction with the lowering of the operating rod 72, the movable portion 52 withdraws from the outer position O to the inner position I. As a result, the screwing engagement between the sliding projection 56 of the movable portion 52 and the screw groove 16 of the hanging cylinder 15 is released. In this state, as shown in FIG. 4(A), when the pressing-down head 92 is pushed down, the content is ejected from the injection holes 93, and the sliding partition 13 rises above the lower limit height T by the biasing force of the first biasing means C1. Then, when the pressing-down of the pressing-down head 92 is released, the pressing-down head 92 returns to its original position by the biasing force of the second biasing means C2. When the sliding partition 13 reaches the upper limit height U, the content is used up, and when refilling the content, as shown in FIG. 4(B), the injector 80 is removed from the mouth-neck portion 10 for refilling. Then, when the gripping portion 78 is pushed up, due to the action of the cam means, the movable portion 52 advances from the inner position I to the outer position O, and the sliding projection 56 of the movable portion 52 is screwed into the screw groove 16 of the hanging cylinder 15. When the gripping cylinder portion 23 is gripped and rotated in this state, the sliding partition 13 is pulled back from the upper limit height U to the lower limit height T. In this state, the content is injected from the mouth-neck portion 10, and when the injector 80 is attached to the mouth-neck portion 10, the filling operation is completed.

[0037] According to the above configuration and operation, since the operating mechanism A for returning the sliding partition 13 that has reached the upper limit height U to the lower limit height T is provided along with the injection of the contents from the injector 80, the contents can be refilled, which is convenient to use. For the return operation, the procedure is simple because the gripping portion 78 may be rotated after raising the operating rod 72. Since the positioning means Q for the operating rod 72 is provided, the screwed state between the screw groove 16 and the sliding projection 56 can be appropriately maintained. The fine movement of the sliding projection 56 entering and leaving the screw groove 16 can also be accurately realized using the cam means, and the operability is good. Furthermore, since the hanging cylinder 15 and the sliding projection 56 are screwed together at a plurality of locations in the circumferential direction of the hanging cylinder 15, the sliding partition 13 can be stably pulled down.
