  A pair of lateral ribs 33 are provided on the inner peripheral surface of the adapter 32 so as to be spaced apart from each other in the axial direction. These lateral ribs 33 are each formed in an annular shape extending along the inner peripheral surface of the adapter 32 over the entire circumference of the inner peripheral surface and have a semicircular cross section, as shown in FIG. The pipe body 31 is in slidable contact with the outer peripheral surface. The horizontal rib 33 abuts on the outer peripheral surface of the pipe body 31, so that the space between the pipe body 31 and the adapter 32 is sealed in a liquid-tight manner.

  In the present embodiment, the pair of horizontal ribs 33 is provided on the inner peripheral surface of the adapter 32, but it is sufficient that at least one horizontal rib 33 is provided on the inner peripheral surface of the adapter 32. When the pair of horizontal ribs 33 are arranged side by side in the axial direction, the adapter 32 can be held straight by the pipe body 31 without being inclined in the axial direction by the pair of horizontal ribs 33.

Each of these protrusions 36 protrudes downward from the lower end surface, and a gap is provided in the circumferential direction between adjacent protrusions 36. Therefore, the adapter 32 can come into contact with the bottom wall of the container body at the protrusion 36. In the state where the projection 36 is in contact with the bottom wall, a gap is formed between the lower end surface of the adapter 32 and the bottom wall of the container body, and a gap is also formed between the adjacent projections 36. Can be sucked from the suction port 32b. For convenience, in each drawing, only one protrusion 36 is denoted by a reference numeral.

  As shown in FIG. 1, the pressing head 40 is provided so as to protrude upward from the top wall 12 of the mounting cap 10. The push-down head 40 is connected to a piston constituting the pump 20, and the piston is driven by operating the mounting cap 10 in the push-down direction (direction toward the cylinder 21) in FIG. 1. The pump 20 can be activated. That is, by operating the push-down head 40 in the push-down direction with respect to the mounting cap 10, the pump 20 is operated to suck the content liquid stored in the container body from the suction port 32 b of the suction pipe 30. Further, it can be ejected from the ejection port 41 provided in the pressing head 40 toward the outside.

  As shown in FIG. 4, the liquid ejecting container 60 according to one embodiment of the present invention is configured by mounting the ejector 1 with a pump on the mouth (not shown) of the container main body 50 that stores the content liquid. can do.

  The container body 50 has a bottle shape having a peripheral wall 50a formed in a cylindrical shape having a larger diameter than the mouth and a bottom wall 50b closing the lower end of the peripheral wall 50a below the mouth to which the ejector 1 with a pump is attached. The glass small bottle formed in the inside contains the content liquid. The content liquid may be, for example, perfume or lotion, but may be other liquids. The container body 50 made of glass has a large variation in the thickness of the bottom wall 50b due to individual differences that occur in its molding. However, the pump-equipped ejector 1 having the above-described configuration is provided in such a container body 50. In contrast, the suction port 32b of the suction pipe 30 can be easily attached to the mouth portion of the container body 50 so as to be close to the bottom portion 50b of the container body 50.

  The procedure for mounting the pump-equipped ejector 1 on the mouth of the container body 50 will be described below.

  First, as shown in FIG. 2, the adapter 32 is positioned at the initial position with respect to the pipe body 31 such that the length from the upper end of the adapter 32 to the upper end of the pipe body 31 is A. State. The length A from the upper end of the adapter 32 to the upper end of the pipe body 31 is such that the projection 36 of the adapter 32 abuts against the bottom wall 50b of the container body 50 before the mounting cap 10 is completely screwed to the mouth. It is. In the initial position, as described above, the lower end of the pipe body 31 abuts on the upper end of the vertical rib 34. Therefore, the adapter 32 can be easily set to the initial position by manually inserting the adapter 32 into the pipe body 31 until the resistance is increased by the lower end of the pipe body 31 coming into contact with the upper end of the vertical rib 34. . The length A from the upper end of the adapter 32 to the upper end of the pipe body 31 is such that the protrusion 36 of the adapter 32 contacts the bottom wall 50b of the container body 50 when the pump-equipped ejector 1 is attached to the mouth of the container body 50. The contact length is set.

  Next, the mounting cap 10 of the pump-equipped ejector 1 in which the adapter 32 is set to the initial position is screwed to the mouth portion of the container main body 50 to attach the ejector 1 with the pump to the mouth portion. At this time, the length A from the upper end of the adapter 32 to the upper end of the pipe body 31 is such that the protrusion 36 of the adapter 32 contacts the bottom wall 50b of the container body 50 before the mounting cap 10 is completely screwed to the mouth. Since the contact length is set, the adapter 32 moves relative to the pipe body 31 in the direction of shortening the length A from the initial position when the protrusion 36 contacts the bottom wall 50b. In the state where the mounting cap 10 of the pump-equipped ejector 1 is completely screwed to the mouth of the container body 50 and the mounting is completed, as shown in FIG. The length up to the upper end is a length B shorter than the length A, and the adapter 32 is positioned above the initial position with respect to the pipe body 31. At this time, the protrusion 36 remains in contact with the bottom wall 50 b, and the adapter 32 is restrained with respect to the pipe body 31 by the outer peripheral surface of the pipe body 31 contacting the vertical rib 34, and the pipe body 31. Therefore, the suction pipe 30 is maintained at a length close to the bottom wall 50b so that the suction port 32b is separated from the bottom wall 50b by the protrusion height of the protrusion 36. Will be. In this way, the suction port 32b of the suction pipe 30 is separated from the bottom wall 50b by the protrusion height of the protrusion 36 by a simple operation of simply mounting the pump-equipped ejector 1 on the mouth of the container body 50. Thus, it can arrange | position close to the bottom wall 50b. Therefore, when the pressing head 40 is pressed down, the content liquid stored in the container body 50 can be sucked into the pump body 20 through the suction port 32b from the gap between the adjacent protrusions 56 and Even if the remaining amount of the stored content liquid decreases, the content liquid can be sucked into the pump 20 through the suction port 32b to the end.

  Even when the ejector 1 with a pump having such a configuration is attached to the mouth of another type of container body 50 having an inner height different from that of the container body 50 shown in FIG. Since the length of the suction pipe 30 is adjusted in accordance with the inner height of the container main body 50, the length from the upper end of the adapter 32 to the upper end of the pipe main body 31, for example, as shown in FIG. Even for a container body 50 having a low inner height such that the length is zero, the pump-equipped ejector 1 with the adapter 32 as an initial position is simply attached to the mouth of the container body 50, and is used for suction. The suction port 32b of the pipe 30 can be disposed close to the bottom wall 50b so as to be separated from the bottom wall 50b by the protruding height of the protrusion 36.

  As shown in FIG. 4B, when the length A from the upper end of the adapter 32 to the upper end of the pipe body 31 becomes 0, the lower end of the pipe body 31 comes into contact with the contact surface 35a. The upward movement of the adapter 32 is restricted.

  As described above, in the pump-equipped ejector 1 having the above-described configuration, the inside height is different by a simple operation of simply mounting the pump-equipped ejector 1 on the mouth of the container body 50 with the adapter 32 as the initial position. The suction port 32b of the suction pipe 30 can be placed in close proximity to the bottom wall 50b of the container body 50 with respect to the container body 50. Accordingly, it is not necessary to prepare a plurality of types of pump-equipped ejectors 1 with respect to a plurality of types of container main bodies 50 having different inner heights, thereby improving the versatility of the pump-equipped ejector 1, and thus the pump-equipped ejector 1 The cost of the liquid ejection container 60 using can be reduced. In addition, since it is not necessary to prepare a plurality of types of pump-equipped ejectors 1 having slightly different lengths of the suction pipe 30, in the process of assembling the pump-equipped ejector 1 to the container body 50, It is possible to prevent erroneous assembly of other types of pumped ejectors having different lengths.

  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, in the above embodiment, the container body 50 is a glass small bottle, but the material, shape, size, etc. of the container body 50 such as a synthetic resin bottle can be variously changed. is there.
