Referring to FIGS. 3 and 4, a stopper with a stopper according to the present invention will be described. Fig. 3 is a side sectional view of one side of the stopper with the stopper roughly cut in half from the center, and Fig. 4 is an exploded view of the main members of Fig. 3. Cross section of the
(B) is a sectional view of the small-diameter tubular body, and (c) is an external perspective view of the plug joint. The large-diameter cylindrical body 10b is different from those shown in FIGS. 1 and 2 in that an opening 24b provided in the outer wall surface 21b is bulged outward from the outer wall surface 21b to form a cylindrical shape. This is at the position where the locking projection 36b is provided on the inner wall of the body 25b. Other structures, the protrusion 22b, and the female screw 23b have the same structure. The small-diameter cylindrical body 30b also has the same structure as the small-diameter cylindrical bodies 30 and 30a in FIGS. (See FIGS. 4A and 4B). Swelling cylindrical body 25
The reason why b is protruded longer than the outer wall surface 21b is to firmly connect with a plug joint described later. The bulged tubular body 25b may be formed integrally with or separate from the large-diameter tubular body 20b, and may be connected to each other using a fixing means such as a screw.

The plug 40 connected to the lid is a main body 4
1. Consists of a plug joint 50 and an L-shaped nozzle 46. Plug body 41
Has a hollow cylindrical body, one end of which is closed by a lever 43 and the other end of which is open, and a valve hole 42 communicating with the plug joint 50 is provided in a part of a substantially intermediate portion of the cylindrical body. The other end of the main body 41 is provided with a projection for engagement. The plug joint 50 includes two cylindrical bodies 51 and 52, and one cylindrical body 52 is disposed substantially at right angles to the other cylindrical body 51, and a communication hole 53 is formed between the cylindrical bodies 51 and 52. It is perforated so that water can pass through this communication hole 53. The length of one tubular body 51 is longer than the sum of the bulging tubular body 25b and the protrusion 22b, and when the tubular body 51 is connected to the lid 10b, the tip of the tubular body 51 is a small-diameter tubular body. The length is extended to the vicinity of the opening of 30b to facilitate connection with a relay pipe and a water purifier described later. Also,
One end of the outer peripheral surface of the cylindrical body 51 has a male screw 55,
A coupling projection 56 is provided at a position a little away from 5, and a closing member, an annular groove 57 for mounting an O-ring, and a locking projection 58 are further provided at a distance. In addition, an annular groove is provided on the inner wall peripheral surface of the other cylindrical body 52 for coupling with the coupling projection of the valve body.
(See FIG. 4 (c))

One end 47 of the L-shaped nozzle 46 connected to one end of the plug body 41 is opened as a water discharge port, and an inner wall of the other end 49 is provided with an annular groove to be connected to the other end of the plug body 41. Further, a packing or the like may be inserted into the connection point between the main body 41 and the L-shaped nozzle 46 to prevent the fluid flowing inside from leaking outside. May also be used as one end. That is,
The cap 60 is made of a material such as rubber or resin, one of which is used as a packing having an opening 61, and the opening 61 and the cap 60 are connected by a strip 62 of the same material. (See Fig. 5)

Assembly of the stopper 40 to the lid is performed in the following procedure. First, one end of the plug main body 41 is inserted into the opening 54 of the cylindrical body 52 of the plug joint 50, and inserted until the protrusion 44 comes into contact with one end of the cylindrical body 52. Then, the coupling portion fits into the annular groove, and both are fixed. Next, one end 49 of the L-shaped nozzle 46 is attached and fixed to one end of the plug body 41. In this assembled state, the stopper main body 41 and the cylindrical body 52 can be insulated in a liquid-tight manner on the inner wall surface of the cylindrical body 52 by the rotation of the lever 43 and can be rotated. A water passage is formed at a position where the water flows, and water can be passed or stopped by turning the lever 43.

Next, the assembled plug 40 is inserted into the bulging tubular body 25b of the lid 10b assembled in advance from the opening end thereof. Thereby, the engagement protrusion 56 of the tubular body 51 is formed.
Engages with the locking projection 36b, and the tip of the bulging tubular body 25b abuts on the locking projection 58, so that the lid 10b and the plug 40 are firmly connected. Further, in order to mount the stopper with the stopper on a container (not shown) such as a plastic tank, the opening size of the container matches the size of the small-diameter cylindrical body of the lid, as in the case of mounting the lid described above. If it is, the female screw 32b of the small-diameter cylindrical body 30b is aligned with the male screw (not shown) of the container opening, and the large-diameter cylindrical body 20b is rotated clockwise. Then
Since the small-diameter cylindrical body 30b is connected to the large-diameter cylindrical body 20b by a polygonal ring 35, the small-diameter cylindrical body 30b rotates with the rotation of the large-diameter cylindrical body 20b, and Attached to the opening. At this time, since the lid 10b and the plug joint 50 are fitted and connected to each other, the lid 10b and the plug joint 50 can be rotated relative to each other, and after the lid 10b is firmly connected to the container opening, the position of the plug 40 is changed. Can be easily changed. Meanwhile,
When the diameter of the container matches the size of the large-diameter cylindrical body 20b, the large-diameter cylindrical body 20b is similarly rotated and coupled to the opening of the container. At this time, the small-diameter cylindrical body 30b functions as a guiding unit.

FIG. 5 is a sectional side view of a simple water purifier in which a water purifier is mounted on a lid with a stopper, cut along a plane perpendicular to the longitudinal direction. This simple water purifier includes a lid 10b, a stopper 40, a relay pipe 70, and a water purifier 80. Lid 10b, stopper 4

2 is a hollow cylindrical body 81 closed and the other end 83 is open;
A purification filter 90 disposed around the cylindrical body 81
Consists of The hollow tubular body 81 has a flange portion 84 formed at a closed portion, and the other end open end 83 is slightly protruded and bulged so that a relay pipe to be described later can be fitted to this portion. Further, the space between the flange portion 84 and the raised portion 85 is made somewhat longer, and a plurality of fine holes are formed in the longitudinal portion 86 in a mesh shape. Next, a fibrous activated carbon 90 was used as a purification filter on the surface.
Is coated. Reference numeral 87 denotes a fiber filter, which is provided as necessary. The size of the water purifier 80, especially the cylindrical body 81
Is smaller than this opening diameter in relation to the opening diameter of the container. In addition, as the purification filter, a known filter, for example, a filter in which a hollow cylindrical body is filled with a fiber filter on the surface thereof and an ion-exchange catalyst filter is filled therein may be used.

A relay pipe 70 is used to connect the water purifier 80 and the plug joint 50. This relay pipe 70 is a hollow cylindrical body, both ends are open, one end 71 is slightly tapered, and an annular groove for mounting an O-ring is provided on the outer peripheral surface in the middle, and the other end 72 is slightly radiused. In this case, when the expanded surface comes into contact with the packing 36b, a more liquid-tight effect is obtained. In addition, a female screw 73 for connection is engraved on the inner wall portion peripheral surface. Although the water purifier 80 and the plug joint 50 are connected using the relay pipe 70, the open end 83 of the water purifier 80 is connected to the plug joint 50 without using the relay pipe 70.
It can also be connected directly to the tip. The open end 83
It is needless to say that the length and the coupling means 73 can be arbitrarily changed according to the design.

Attachment of the water purifier 80 to the plug joint 50 is performed by first connecting the female screw 73 provided at one end of the relay pipe 70 to the joint 5.
Then, the open end 83 of the water purifier 80 is fitted to the other end 71 of the relay pipe 70. In addition, in order to attach the simple water purifier to the opening of the container (not shown), the aperture size of the container opening is adapted to the size of the small-diameter cylindrical body of the lid, similarly to the attachment of the lid described above. In some cases, the female screw 32b of the small-diameter tubular body 30b is aligned with a male screw (not shown) of the container opening, and the large-diameter tubular body 20b is rotated clockwise. Then, the small-diameter cylindrical body 30b becomes the large-diameter cylindrical body 2
Since the large-diameter cylindrical body 20b is rotated, the small-diameter cylindrical body 30b is rotated and attached to the opening of the container because the large-diameter cylindrical body 20b is rotated. At this time, since the lid 10b and the plug joint 50 are fitted and connected to each other, the lid 10b and the plug joint 50 can be rotated relative to each other, and after the lid 10b is firmly connected to the container opening, the position of the plug 40 is changed. Can be easily changed. On the other hand, the container has a large diameter cylindrical body 2.
When the size matches the size of 0b, the large-diameter cylindrical body 20b is similarly rotated and connected to the opening of the container. At this time, the small-diameter cylindrical body 30b functions as a guiding unit.
