Between the lever cap 140 and the housing 100, one of concave and convex portions elastically fitted to each other is formed. In the present embodiment, the lever cap 14
As shown in FIGS. 10 and 11, four elastic claws 141... Protruding inward in the radial direction are formed radially on the 0 as convex portions.

On the other hand, the cylinder portion 1 of the housing 100
On the outer periphery of 01, as shown in FIGS.
A total of four depressions 104 and 105 into which the respective elastic claws 141 fit are formed radially. The four recesses 104 and 105 are classified into two types according to the difference in their shapes. The first recess 104 and the first recess 104 opposed to each other, and the second recess 105 and the second recess 105 are opposed to each other.
The depressions 105 are formed in the same shape.

As shown in FIGS. 1 and 11, the first concave portion 104 is located on the left and right of the outer periphery of the cylinder portion 101 of the housing 100, and is substantially U-shaped in cross section in accordance with the shape of the elastic claw 141. .

In the embodiment shown in the drawings, four convex rotation angle regulating pieces 142 are formed on the lever cap 140,
Although the concave rotation angle regulating groove 107 is formed in the housing 100, a concave rotation angle regulating groove may be formed in the lever cap 140, and a convex rotation angle regulating piece may be formed in the housing 100. In addition, four rotation angle restriction pieces 142 and four rotation angle restriction grooves 107 are formed. However, one, two, three, or five or more rotation angle restriction pieces may be formed. The claw 141 only has to be disengaged from the first and second depressions 104 and 105, and is not limited to 45 degrees.

In the embodiment shown in the drawings, the lever cap 140 is formed with the elastic claw 141 as a convex portion, and the housing 100 is formed with the first and second concave portions 104 and 105 as concave portions. The first and second recesses 10 are provided on the lever cap 140.
4, 105 may be formed, and the elastic claw 141 may be formed on the housing 100 side. Further, each of the four elastic claws 141 and the first and second elastic claws 141 are provided.
Although the depressions 104 and 105 are formed, the number of these is not limited to four, and may be, for example, two, three, or five or more. Further, although the shapes of the first recess 104 and the second recess 105 are different from each other, they may be formed in the same shape.

On the other hand, a sharp-pointed film opener 150 is fitted in the inflow pipe 102 of the housing 100, as shown in FIG. The film opener 160 is inserted into the discharge pipe 21 of the film bag 20, and is used to break and pierce the film bag 20, as shown in FIG. As shown in FIG. 4, an O-ring 170 is fitted around the outer circumference of the inflow pipe 102, and the space between the inflow pipe 102 and the discharge pipe 21 of the film bag 20 is sealed through the O-ring 170.

Further, as shown in FIG. 4, a pair of upper and lower locking claws 106, 106 protruding from the upper and lower periphery of the inflow pipe 102 protrude in the middle of the length of the inflow pipe 102. Each locking claw 106 is formed in a saw-tooth cross section with the slope facing the opening end side of the inflow pipe 102. On the other hand, as shown in FIG. 1, a pair of upper and lower guide grooves 94 are formed in the communication pipe 90 of the adapter 50 so as to fit into the respective engagement claws 106.
The insertion direction of the inflow pipe 102 is regulated.

Then, when the inflow pipe 102 is inserted into the communication pipe 90 of the adapter 50, each locking claw 106 is moved to each locking hole 92 of the pair of upper and lower elastic pieces 91 of the adapter 50 as shown in FIG.
Then, the adapter 50 and the housing 100 are connected by fitting into the snap due to the elasticity of each elastic piece 91. On the other hand, when the inflow pipe 102 is forcibly extracted from the communication pipe 90 of the adapter 50, each elastic claw 106 is pushed by each locking claw 106 to bend, and each locking claw 106 is thereby locked. The hole 92 is disengaged and the inflow pipe 102 comes out of the communication pipe 90 of the adapter 50. In this way, the bending of each elastic piece 91 causes the inflow pipe 102
As the elastic pieces 91 are prevented from being bent by the stopper 60, the inflow pipe 102 is prevented from accidentally coming off.

In the embodiment shown in the drawings, a pair of upper and lower elastic pieces 91 are formed in the communication pipe 90 of the adapter 50, and each of the elastic pieces 91 is formed with a locking hole 92 as a recess.
A pair of upper and lower locking claws 106 as convex portions
Conversely, a locking claw 106 as a projection is formed in the communication pipe 90 of the adapter 50, and the inflow pipe 10 of the housing 100 is formed.
2, a locking hole 92 as a concave portion may be formed. Also,
Although a pair of upper and lower locking claws 106 and locking holes 92 are formed, the invention is not limited to this, and they may be formed in the left-right direction, or may be formed in three or more radially. (Stopper) The stopper 60 is formed in a cylindrical shape having an inner diameter that fits into the communication pipe 90 of the adapter 50, as shown in FIGS.

As shown in FIGS. 6 and 8, a pair of upper and lower elastic pieces 91 of the communication pipe 90 of the adapter 50 are provided on the inner periphery of the stopper 60 so as to allow the elastic piece 91 to bend radially outward. A lock release groove 61 is formed. For this reason, when the lock release groove 61 is located around each elastic piece 91 as shown in FIG. 8, each elastic piece 91 can bend into the lock release groove 61. In this position, since each elastic piece 91 bends, insertion of the inflow pipe 102 of the housing 100 into the communication pipe 90 of the adapter 50 and forcible removal are possible.

On the other hand, when the stopper 60 rotates, the inner diameter of the stopper 60 is set equal to the outer diameter of the communication pipe 90 of the adapter 50 as shown in FIG. Outward deflection is prevented. Therefore, the inflow pipe 102 of the housing 100 is connected to the communication pipe of the adapter 50.
When inserted into the connector 90, the inflow pipe 102 of the housing 100 is locked in the communication pipe 90 of the adapter 50.

On the other hand, as shown in FIGS. 7 and 9, a pair of upper and lower protrusions 93 projecting from the outer periphery of the communication pipe 90 of the adapter 50 fits on the inner periphery of the stopper 60, and extends in a curved manner in an arc shape. A pair of fitting grooves 62, 63 are formed, and each fitting groove 62, 63 is formed.
A partition wall 64 that divides the inside of each of the fitting grooves 62 and 63 into a first fitting groove 62 and a second fitting groove 63 protrudes from the center. In this embodiment, as shown in FIG.
In a state in which the stoppers 60 are fitted in the first fitting grooves 62, the elastic pieces 91 and the lock release grooves 61 are alternately shifted as shown in FIG.

On the other hand, when the stopper 60 is rotated, the projection 93 of the adapter 50 passes over the partition wall 64 between the first and second fitting grooves 62 and 63, and as shown in FIG. Second
It moves to the fitting groove 63. At this time, a click feeling is given to the operator who rotates the stopper 60. And adapter 50
At the position where the projection 93 moves to the second fitting groove 63 as shown in FIG. 9, each unlocking groove 61 is located around each elastic piece 91, which is the unlocking position of the stopper 60.

When the projection 93 of the adapter 50 moves over the step 65 to the second fitting groove 63 as shown in FIG. 4, the stopper 60 does not come off the outer periphery of the communication pipe 90 of the adapter 50. In the embodiment shown in the drawings, a pair of upper and lower protrusions 93 as protrusions is formed on the adapter 50, and first and second fitting grooves 62, 6 as recesses are formed on the inner periphery of the stopper 60.
On the contrary, the first and second fitting grooves 62 and 63 as recesses are formed on the outer periphery of the adapter 50, and a pair of projections 93 are formed on the inner periphery of the stopper 60 as projections. May be. Further, the number of the projections 93 and the first and second fitting grooves 62 and 63 is not limited to one pair, and may be one, three or more. (Mounting Method) Next, a mounting method of the filled liquid discharging device 10 having the above-described configuration will be described.

First, although not shown, a perforation on the side wall of the box 30 is cut out to open the outlet 31. Next, as shown in FIG. 1, the pouring tube 21 of the film bag 20 is pulled out from the opened outlet 31. Remove the tip cap 26.

Thereafter, the distal end annular rib 25 of the pouring tube 21 is inserted from the open upper surface of the insertion groove 81 of the adapter 50 as shown in FIG. Thereby, the discharge pipe 21 and the communication pipe 90 of the adapter 50 communicate with each other as shown in FIG. At this time, since the adapter 50 is bent in an L-shaped cross section along the corner of the box 30, the adapter 50 is bent.
Adheres to the corner of box 30. In particular, when the outlet pipe 21 of the film bag 20 is turned sideways, the adapter 50 rests on the lower piece and the bottom of the box 30 rests, and the adapter 50 is stably held.

Next, the sharpened film opener 160 of the cock 40 in the assembled state is inserted as shown in FIG.
Insert according to the communication tube 90 of the adapter 50. The inserted film opener 160 is connected to the communication tube 90 of the adapter 50.
Through the discharge pipe 21 of the film bag 20.
Here, when the film opener 160 is strongly inserted, as shown in FIG. 5, the film bag 20 is broken at the sharp tip and a hole is made in the film bag 20. At this time, since the liquid in the film bag 20 rapidly flows into the film opener 160, the film opener 160 is positioned at a position where the discharge pipe 21 of the film bag 20 is directed upward.
It is better to make a hole.

When the film opener 160 is inserted firmly, the discharging pipe 21 of the film bag 20
Trying to retract from the outlet 31 of the
Is formed to be larger than the outlet 31 of the box 30, so that the adapter 50 abuts on the outer surface of the box 30 to prevent the pouring tube 21 from being retracted into the box 30. On the other hand, when the film opener 160 is inserted, the inflow pipe 102 of the cock 40 also advances into the communication pipe 90 of the adapter 50. At this time, a pair of upper and lower locking claws 106 of the inflow pipe 102 are
Abuts on a pair of upper and lower elastic pieces 91.

Here, the inflow pipe 102 is connected to the film opener 1
When the elastic piece 91 is strongly inserted into the communication pipe 90 integrally with the tube 60, each elastic piece 91 is pressed by each locking claw 106 and bends radially outward. Thereafter, when each locking claw 106 advances to the position of the locking hole 92 of each elastic piece 91, each elastic piece 91 is snapped back by the elastic force of the resin, and as shown in FIG. Stop claws 10
6 fit into each locking hole 92.

As a result, the adapter 50 and the cock 40 are connected, and at this connection position, a hole is formed in the film bag 20 by the film opener 160 as described above. Thereafter, when the stopper 60 is rotated as shown in FIG.
Is prevented from bending outward in the radial direction, and the cock 40 is locked in the connected state.

At this time, the projection 93 projecting from the outer periphery of the distal end portion of the communication pipe 90 of the adapter 50 passes over the partition wall 64,
As shown in FIG. 7, it moves from the second fitting groove 63 to the adjacent first fitting groove 62. At this time, a click feeling is given to the operator who rotates the stopper 60 to notify that the stopper 60 has moved to the lock position. (How to Use) On the other hand, when the liquid in the film bag 20 is poured, the lever 110 may be lowered. In addition, the lever 110 may be raised in the opposite direction, and when the lever 110 is raised, the lever 110 is locked at a raised position (not shown).
The valve member 130 is maintained at the raised position in the cylinder portion 101.

First, how to remove the cock 40 will be described. As shown in FIG. 8, the stopper 60 is rotated to position each lock release groove 61 of the stopper 60 around each elastic piece 91 of the adapter 50. In this state, the inflow pipe of cock 40
102 is forcibly removed from the communication pipe 90 of the adapter 50. At this time, the projection 93 protruding from the communication pipe 90 of the adapter 50
Moves over the partition wall 64 from the first fitting groove 62 to the adjacent second fitting groove 63 as shown in FIG. At this time, a click feeling is given to the operator who rotates the stopper 60 to notify that the stopper 60 has moved to the unlock position.

After the stopper 60 is unlocked, when the inflow pipe 102 of the cock 40 is removed, each elastic piece 9 of the communication pipe 90 of the adapter 50 is removed.
1 is pushed by each locking claw 106 of the inflow pipe 102 of the cock 40,
The stopper 60 bends radially outward in each lock release groove 61. For this reason, the inlet pipe 102 of the cock 40 is
Exit from the communication pipe 90 of. Next, the insertion groove of the adapter 50
The discharge pipe 21 of the film bag 20 may be withdrawn from the open upper surface of 81.

In this way, after use, the adapter 50 and the cock 40 can be collected and reused.
