Even if the diameter is large, the outer diameter of the upper portion of the bowl-shaped portion 31 is slightly smaller than the inner diameter of the overhang portion 53 b at the upper end of the holder mouth portion 53. Thereby, while it is easy to insert the hook-like part 31 into the holder mouth part 53, when the hook part 32 is thinly deformed, the upper end part of the hook-like part 31 is also deformed and the overhanging part 53b at the upper end. It is easy to make it close. The lower part of the bowl-shaped part 31 has a small diameter and is always away from the inner peripheral surface of the holder mouth part 53. More specifically, the lower portion of the bowl-shaped portion 31 has a tapered shape (the tapered shape in which the inclination angle decreases stepwise) in which the outer diameter decreases toward the bottom. Further, the bowl-shaped portion 31 is provided with a hose through hole 33 passing through the hose 81 of the liquid jet pump 8 in the center of the bottom in the vertical direction. The outer peripheral surface of the hose 81 is tightly sealed to the inner peripheral surface of the hose through-hole 33.

The usage method of the adapter 1 of 1st embodiment mentioned above is as follows.
(1) Open the refill pack holder 5 and put the refill pack 9 therein.
(2) As shown in FIG. 4, the refill pack holder 5 is closed and the upper part of the refill pack 9 is sandwiched. At this time, the upper edge portion (seal portion) of the refill pack 9 is set to be higher than the holder mouth portion 53.
(3) About the circumference | surroundings of the holder opening part 53, the refill pack 9 is cut with scissors along the dotted line of FIG. 4, so that the adapter main body 2 can be connected.
(4) At this time, as shown in FIG. 5 (a), the refill pack 9 is in a state in which the front and rear sheets 91 overlap each other in the holder opening 53, so that a finger or the like is placed between the overlapping sheets 91. Then, a bag mouth portion 92 is formed as shown in FIG.
(5) The packing 3 is fitted into the adapter main body 2 and the lower connecting portion 23 of the adapter main body 2 is screwed into the holder opening 53 as it is. At this time, care is taken that the hook-shaped portion 31 of the packing 3 is inserted into the bag mouth portion 92. As shown in FIGS. 6 (a) and 7 (a), the sheet 91 of the bag mouth portion 92 is interposed between the overhanging portion 53b of the holder mouth portion 53 and the hook-like portion 31 at the start of screwing. Not only does it have gaps, it can be screwed in with light force. Then, immediately before the end of the screwing, as shown in FIG. 7B, the second protruding portion 53b from the top of the holder mouth portion 53 and the boundary between the upper portion and the lower portion of the bowl-shaped portion 31 are in contact with each other. And closely. Further, when slightly screwed, the sheet 91 of the bag mouth portion 92 and the flange portion 32 of the packing 3 are sandwiched between the top wall 24 of the adapter body 2 and the upper end surface of the holder mouth portion 53, and these are deformed thinly. Close. At this time, as shown in FIG. 6 (b), at the portion where the front body 6 and the rear body 7 are fitted by unevenness in the holder mouth portion 53, the upper end portion of the hook-like portion 31 is deformed by the deformation of the hook portion 32. The sheet 91 of the bag mouth portion 92 and the upper end portion of the hook-like portion 31 of the packing 3 are sandwiched between the inner rib 61a and the mouth spreading wall 27 of the adapter main body 2 so as to be in close contact with each other. On the other hand, as shown in FIG. 7 (b), the sheet 91 and the packing 3 of the bag mouth portion 92 are similarly provided between the protruding portion 53 b at the upper end and the widening wall 27 in another portion of the holder mouth portion 53. The upper end portion of the bowl-shaped portion 31 is in close contact with each other. The protruding portion 53b at the upper end is made thicker than the other, thereby improving the adhesion to the inner peripheral surface side.
(6) The hose 81 of the spray type liquid jet pump 8A is inserted into the widening wall 27 of the adapter body 2, and then the fixing cap 83 of the liquid jet pump 8A is screwed into the upper connecting portion 22 of the adapter body 2. Then, the connecting operation is completed as shown in FIG.

Since the lower end surface 25b of the outer peripheral wall 25 comes into close contact with the upper end surface of the holder neck portion 54 when the portion is firmly sandwiched and screwed in completely, the sealing performance is extremely excellent. Therefore, even if the refill pack holder 5 falls down, it is difficult for the solution in the refill pack 9 to leak out from the connecting portion between the lower connecting portion 23 of the adapter body 2 and the holder opening 53. Similarly, even if the refill pack holder 5 falls down, the hose 81 is in close contact with the hose through-hole 33 of the packing 3 so that the internal solution is difficult to leak out.

  Next, a difference between the second embodiment of the adapter 1 shown in FIG. 8 or FIG. 9 and the first embodiment will be described. In the second embodiment, the adapter body 2 does not have the skirt wall 26, the packing 3 has a general ring shape, and is sandwiched between the top wall 24 and the upper end surface of the holder mouth portion 53. Is one of the differences. Due to this difference, the second embodiment is inferior to the first embodiment in terms of sealing performance, but sufficient practicality is ensured.

  Another difference is that the liquid ejection pump 8 pushes down the head 82 to discharge the liquid in the form of bubbles, and is a bubble ejection type liquid ejection pump 8B (type without the lever 85). In this case, since the relationship between the outer diameter of the holder mouth 53 <the inner diameter of the fixing cap 83, that is, the outer diameter of the holder mouth 53 is too smaller than the inner diameter of the fixing cap 83, the fixing cap 83 is screwed into the holder mouth 53. The adapter body 2 is provided for this purpose. And the adapter main body 2 has the outer peripheral wall 25 of the lower connection part 23 suspended from the cylindrical main body intermediate part 21 with the same outer diameter, and the widening wall 27 has a tapered shape. The upper part of the hose 81 of the liquid jet pump 8 is in contact with the lower end portion of the inner peripheral surface of the widening wall 27 without any substantial gap. In addition, since the usage method of the adapter 1 of 2nd embodiment is the same as that of 1st embodiment, it abbreviate | omits.

  Next, a third embodiment of the adapter 1 shown in FIGS. 11 to 16 will be described focusing on differences from the first embodiment. This is used for the spray type liquid jet pump 8A as in the first embodiment. In the third embodiment of the adapter 1, the adapter 1 is divided into three parts (three parts), that is, two parts (two parts) of the adapter body 2 and one piece (one part) of the packing 3. Is the biggest difference. Hereinafter, it demonstrates in order.

  The adapter main body 2 is divided into two parts: a fixed cap 83 of the spray-type liquid jet pump 8A, a joint portion 2a connected to the holder opening 53, and a packing holding portion 2b to which the packing 3 is attached.

  The joint portion 2a does not have the widening wall 27 like the adapter main body 2 of the first embodiment, but other configurations, that is, the main body intermediate portion 21, the upper connecting portion 22, and the lower connecting portion 23 The top wall 24, the outer peripheral wall 25, and the skirt wall 26 are provided.

  The packing holding portion 2b includes a lower ceiling wall 24a sandwiched between the upper end surface of the holder mouth portion 53 and the top wall 24, a widening wall 27 depending from the inner peripheral side of the lower ceiling wall 24a, and a lower ceiling wall 24a. And a guide sleeve 28 that hangs down from an intermediate portion in the radial direction. The packing holding part 2b is a synthetic resin product that is more slippery (made of a material having a small frictional resistance) than the joint part 2a.

  The lower ceiling wall 24 a has an annular shape with a smaller outer diameter than the ceiling wall 24. The widening wall 27 and the guide sleeve 28 are formed concentrically with respect to the lower ceiling wall 24a.

  The guide sleeve 28 has a tapered shape with an outer peripheral surface facing downward so that it can be easily inserted into the holder opening 53. Further, the guide sleeve 28 has a shorter overall length than the opening widening wall 27, and more specifically, in the relationship with the holder mouth 53, the guide sleeve 28 projects inward from the lower side (more specifically, the height intermediate portion). It hangs down to the upper side of the overhanging portion 53b for close contact. The outer diameter of the guide sleeve 28 is formed to be smaller than the inner diameter of the holder mouth portion 53, so that when the guide sleeve 28 is accommodated in the holder mouth portion 53, a gap is formed between them. An accommodating portion 28 a for inserting the upper end portion of the packing 3 is formed between the guide sleeve 28 and the widening wall 27. The inner peripheral surface of the guide sleeve 28 has a small diameter in a stepped shape (stepped shape) upward, and thereby the outer diameter of the accommodating portion 28a expands in a stepped shape downward.

  The packing 3 has a shape without the flange 32 as in the first embodiment, and is configured by the flange 31. The outer peripheral surface of the bowl-shaped portion 31 is the bag mouth portion of the refill pack 9 with respect to the intermediate height portion of the inner peripheral surface of the holder mouth portion 53 (more specifically, the protruding portion 53b for close contact with the intermediate height portion). Close through 92. The bowl-shaped portion 31 is formed such that the upper portion is thicker and the outer diameter is larger than the lower portion. The upper portion has a small diameter in a stepwise manner upward corresponding to the shape of the accommodating portion 28a. On the other hand, the lower part is a taper part 34 whose outer diameter is narrowed toward the bottom, and more specifically, a taper part 34 in which the inclination angle with respect to the vertical is gradually reduced (two steps). is there. The outer diameter of the upper tapered portion 34 is larger at the lower end than the inner diameter of the close-out overhang portion 53b of the holder mouth portion 53, and smaller at the upper portion. In addition, the same diameter part is provided between the upper taper part and the lower taper part.

  The refill pack holder 5 used in the third embodiment is different from that used in the first embodiment in that the protruding portion 53b is not provided above the holder mouth portion 53, and the rib 61a serving as the concave portion 61. And the rib 62a used as the convex part 62 differs in the point which is not in the upper part of the holder mouth part 53. FIG.

The usage method of the adapter 1 of 3rd embodiment mentioned above is as follows. (1) to (4) are performed in the same manner as in the first embodiment described above.
(5) The packing 3 is fitted into the widening wall 27 of the packing holding portion 2b, and the packing holding portion 2b is inserted into the holder mouth portion 53 as it is. At this time, the hook-like portion 31 of the packing 3 is inserted inside the bag mouth portion 92 that is open in the holder mouth portion 53. Then, as shown in FIGS. 15 (a) and 16 (a), the upper portion of the tapered portion 34 of the bowl-shaped portion 31 is in light contact with the overhanging portion 53b of the holder mouth portion 53 via the bag mouth portion 92, and the holder The state is such that the lower ceiling wall 24a of the packing holding portion 2b is disposed above the upper end surface of the mouth portion 53 via a gap (floating state). That is, the seal is in an incomplete state.
(6) Screw the joint portion 2a (the outer peripheral wall 25 of the lower connecting portion 23) into the holder mouth portion 53. Then, the lower ceiling wall 24a is pushed downward while the ceiling wall 24 of the joint portion 2a rotates. At this time, due to the relationship of frictional resistance (top wall 24> lower ceiling wall 24a), the packing holding portion 2b does not rotate even if the joint portion 2a rotates. Accordingly, the bag holding portion 2b of the refill pack 9 in the refill pack holder 5 is not twisted, and the packing holding portion 2b is directed downward, and accordingly the upper portion of the taper portion 34 of the packing 3 is the bag mouth portion 92. The packing 3 is deformed by pressing strongly against the overhanging portion 53b of the holder mouth portion 53 through the contact. Finally, as shown in FIGS. 15 (b) and 16 (b), there is no gap between the lower ceiling wall 24a and the upper end surface of the holder mouth 53, and the ceiling wall 24 passes through the lower ceiling wall 24a. And pressed against the upper end surface of the holder mouth portion 53. In this state, the taper portion 34 is in close contact with the overhanging portion of the holder mouth portion via the bag mouth portion 92 while being deformed.
(7) Finally, after inserting the hose 81 of the spray-type liquid jet pump 8A into the widening wall 27 of the adapter body 2, the fixing cap 83 of the liquid jet pump 8A is attached to the upper connecting portion 22 of the adapter body 2. Screw in. That's it.

  Next, a fourth embodiment of the adapter 1 shown in FIGS. 17 and 18 will be described focusing on differences from the third embodiment. This is also used for the spray type liquid jet pump 8A. In the fourth embodiment of the adapter 1, the biggest difference is that the packing 3 has a shape that is more easily deformed.

  The packing 3 has a shape without the flange 32 as in the third embodiment, and is configured by the flange 31. And in the outer peripheral part of the bowl-shaped part 31, the close piece 35 hangs down from the perimeter of the outer peripheral side. The outer peripheral surface of the close contact piece 35 is a tapered portion 34 whose bottom portion is recessed downward. On the other hand, the downward groove 36 is provided in a state of opening downward along the entire inner circumference side of the contact piece 35. The bottom (upper end) of the downward groove 36 is the same as or slightly above the upper end of the tapered portion 34. Since the close contact piece 35 and the downward groove 36 are arranged concentrically, the close contact piece 35 can be deformed (moved) toward the downward groove 36 on the inner peripheral side thereof. In addition, on the inner peripheral side of the downward groove 36, a columnar introduction portion 37, which is a lower portion of the bowl-shaped portion 31, hangs down below the downward groove 36. In consideration of ease of insertion, the outer peripheral surface of the introduction portion 37 has a tapered shape with a slight bottom.

  The usage method of the adapter 1 of 4th embodiment mentioned above is the same as (1)-(7) in the usage method of 3rd embodiment mentioned above. However, it supplements about (6). When the joint portion 2a is screwed into the holder mouth portion 53, the taper portion 34 of the packing 3 is strongly pressed against the close overhang portion 53b of the holder mouth portion 53 through the bag mouth portion 92. As a result, the packing 3 The contact piece 35 is deformed toward the downward groove 36. As described above, the downward groove 36 is skillfully used as a deformation space of the contact piece 35, whereby the outer peripheral surface of the hook-shaped portion 31 and the inner peripheral surface of the holder mouth portion 53 are in close contact with each other. That's it.
