JP5514777B2 - Punching device for drinking water packaging bag in water server - Google Patents

Description

  The present invention relates to a safe punching device for a drinking water packaging bag that is loaded into a water server in a cartridge manner.

  When a drinking water packaging bag made of soft synthetic resin (common name: plastic bag or pack) is turned upside down and loaded into a water server in a cartridge type, the device for punching the center of the packaging bag from below is as follows. It is disclosed in Patent Documents 1 and 2.

  In particular, in the “needle for use in a water server” described in Patent Document 2, if no pushing force is applied to the needle, the tip of the needle does not protrude upward from the bottom surface of the bottle holder, and the user holds the bottle holder. On the other hand, when the plastic bag is taken in and out, it is considered to be a publicly known technique most similar to the present invention in that it is devised not to be injured by the tip of the needle.

JP 2010-143630 A Utility Model Registration No. 3164948

  However, in the configuration described in Patent Document 2, during use of FIGS. 9 and 11 in which the needle (1) perforates the plastic bag (9), the restoring force of the compressed coil spring (22) is always constant in the bottle holder (3). Since it acts as a push-up biasing force, when the drinking water in the plastic bag (9) gradually decreases and becomes lighter, the plastic bag (9) and the bottle holder (3) holding the plastic bag (9) (2) Even if the lower body (17) of the needle (1) is lifted from the packing holder (8) on the side and does not come off from the upper end of the insertion rod (35), the coil spring ( 22), and the bottle holder (3) can be passed through the needle entry / exit hole opened in the ceiling surface of the bottle holder (3) by the drinking water in the plastic bag (9). Bottom leak into (the coil receiving chamber of the spring) (15), and unnecessarily many accumulated results here.

  Therefore, in order to prevent the plastic bag (9) and its bottle holder (3) from rising, the tension of the coil spring (22) is reduced, so that the lower body (17) of the needle (1) and the insertion rod (35) When the sealing force of the sealing member (42) interposed on the fitting surface with the upper end is stronger than the tension of the coil spring (22), the needle (1) is fitted into the insertion rod (35). The coil spring (22) compresses and the plastic bag (9) is perforated sooner than the completion of the process, and the drinking water is still fed from the plastic bag (9) to the needle of the bottle holder (3). There is a risk of leaking into the bottom (coil spring storage chamber) (15) or the upper body (16) of the needle (1) through the intrusion hole and accumulating much in these.

  That is, the overall weight of the plastic bag (9) filled with drinking water and its bottle holder (3), and the tension of the coil spring (22) housed in the bottom (15) of the bottle holder (3) It is possible to adjust / design the sealing force (resistance force of insertion operation) of the seal member (42) interposed in the fitting surface between the needle (1) and the insertion rod (35) to the optimum strength relationship. This is a difficult task, and in combination with the fact that the tension of the coil spring (22) fluctuates due to a natural external force, a stable operation that never leaks from the plastic bag (9) cannot be guaranteed. .

  Also, stainless steel is used as the material of the coil spring (22) housed in the bottom (15) of the bottle holder (3) and the coil spring (30) wound around the valve (27) in the needle (1). Even if this is done, there is no risk of rusting, and there is a problem with safety in applications intended for drinking water.

  Furthermore, since the needle intrusion hole is opened in the ceiling surface of the bottle holder (3), the drinking water in the plastic bag (9) flows correctly through the inside of the needle (1) in the usage state of FIGS. In addition, it also leaks into the bottom (coil spring housing chamber) (15) through the needle in / out hole of the bottle holder (3) and accumulates in the bottom (15).

  The present invention aims to drastically solve such problems, and in order to achieve the object, in claim 1, a drinking water reservoir is provided on the vertical center line of the cup receiving groove recessed from the bowl-shaped top cover. In a water server having a server main body in which a water guide pipe communicating with a tank is fixed and standing, and a drinking water packaging bag having a base fixed to a central portion of the bottom surface,

In this stage, the server main body (10) is fixed and maintained in a state where it is not inserted into the top cover (11). The upper and lower cover of the bag receiving holder (H) is not shown.

  The drinking water packaging bag (22) is integrally molded from a vinyl chloride resin or other transparent or translucent soft thermoplastic resin so that it can be folded and flattened, and a certain amount of drinking water (W) is contained therein. Although it is sealed, a bobbin-shaped (substantially inverted E-shaped cross section) base made of a hard synthetic resin such as polyethylene (PE) resin as shown in FIGS. 26) are fixedly integrated by adhesion, welding, or the like.

  An opening / closing top flange (F) of an elevating guide (G), which will be described later, is sandwiched and used on a concave peripheral surface (27) of the base (26), and the closed use state is locked by an operation ring (R). The open / close top flange (F) of the lifting guide (G) is not detached from the base (26) of the drinking water packaging bag (22).

  The potable adapter (A) of the drinking water packaging bag (22) includes an elevating guide (G), an open / close top flange (F) for covering the opening top surface of the elevating guide (G), and the top flange (F). An operating ring (R) that is fitted to the outside of the lifting guide (G) so as to be movable up and down, a needle (N) that is also inserted into the lifting guide (G) so as to be movable up and down, On-off valve (V) and a pair of upper and lower packings (28) and (29) incorporated in the needle (N), a spacer (S) interposed between the upper and lower sides of both packings (28) and (29), and the needle The bottom cap (B) that covers the bottom of the opening (N) is assembled into an assembly unit, and the sharp apex of the needle (N) passes through the base (26), and the drinking water packaging bag (22) You can drill It has become.

  That is, among the members constituting the perforation adapter (A), first, the elevation guide (G) will be described with reference to a polycarbonate (PC) resin and other transparent or translucent rigid thermoplastic resin. 13 is integrally formed with a basic U-shaped cross section, and a core tube insertion port (30) for allowing the bottom cap receiving core tube (25) of the cup (C) to escape is formed at the center of the bottom surface thereof. Open circularly.

  The body (31) of the elevating guide (G) has a slightly narrow cylindrical shape, and the upper end of the body (31) has a corresponding lower outward engagement of the open / close top flange (F) described later. A plurality (four in total in the illustrated example) of nail receiving holes (32) for receiving the nail are cut out in an overall radial symmetrical distribution type.

  Similarly, a pair of operating ring elevating guide groove rails (33) facing each other in the upper half of the body (31) are notched in a positional relationship so as not to interfere with the claw receiving holes (32). In addition, an outward locking claw (34) serving as a lower limit stopper of the operating ring (R) is connected to the lower and upper guide groove rails (33) at the lower ends (groove bottoms) of both the lift guide groove rails (33). The groove (35) is divided so as to exhibit elasticity. This lower outward locking claw (34) is removably locked in a corresponding lower claw receiving hole (to be described later) of the operation ring (R).

  (36) is a reinforcing rib projecting outward along the opening edge of the lifting guide groove rail (33), and an operation ring (inserted into the body (31) of the lifting guide (G) and fastened. By maintaining R in a state where it is not in close contact with the body (31) of the lift guide (G), the operation ring (R) can be lifted and lowered easily and smoothly.

  On the other hand, from the lower half of the body (31) in the lifting guide (G), a plurality of (in the illustrated example, a total of eight) reinforcing fins (37) distributed in an overall radial symmetry type are directed outward. They are arranged in a protruding state, and can be easily and smoothly inserted into the cup (C) by the lower tapered surface (38).

  Further, a plurality of inwardly engaging claws (39) for receiving the bottom cap (B) of the needle (N) are also provided at the lower end of the body (31), and an overall radial symmetrical distribution is obtained. As a mold, both are defined so as to exhibit elasticity by cutting the split groove (40).

  Next, the open / close top flange (F) of the lift guide (G) is formed from the same polycarbonate (PC) resin as the lift guide (G) or other transparent or translucent rigid thermoplastic resin. Basically, it has a large conical saucer shape substantially corresponding to the top flange receiving flange (24) of the cup (C), which is the first and second flange segments (FIGS. 14-19). F1) and (F2) once divided into two semi-circular shapes in plan view, and can be opened and closed through one longitudinal fulcrum shaft (41) located in the vicinity of the large circular outer peripheral edge It is assembled in a pivoted state.

  And when the 1st, 2nd flange segments (F1) (F2) of the opening and closing top flange (F) are closed, they are sandwiched between the cap (26) of the drinking water packaging bag (22). In addition, a circular mounting base with a small diameter in which the central portion of the first flange segment (F1), which is one of the two flange segments (F1) and (F2), covers the top surface of the lift guide (G). As a board (42), it is inserted and fitted to the opening upper edge part of the raising / lowering guide (G).

  That is, when the first and second flange segments (F1) and (F2) are closed, the first and second flange segments (F1) and (F2) have a semicircular bag receiving seat surface (43) that becomes an overall conical saucer shape for the first time. A semicircular arc-shaped boss (44) that is continuous from the central portion of 43) and is continuous with the whole circle is protruded integrally downward. (45) is an edge skirt which projects downward integrally from the outer peripheral edge of the bag receiving seat surface (43), and is received from below by the top flange tray surface (24) of the cup (C).

  Further, the vertical fulcrum shaft (41) is integrally formed as a wedge-shaped dowel having a split groove (46) at the tip thereof, downwardly projecting from either one of the first and second flange segments (F1) and (F2). And it is inserted and penetrated into a bearing cylinder (47) formed corresponding to the remaining other so as to be freely rotatable. Therefore, there is no risk of getting out. (48) is a notch for restricting the opening degree (θ) of the first and second flange segments (F1) and (F2) to be constant (about 90 degrees in the illustrated example), outside the flange segments (F1) and (F2). It is given to the peripheral part as a substantially square shape in plan view.

  The arc inner peripheral surface (abdominal surface) of the boss (44) in the first and second flange segments (F1) and (F2) serves as a clamping piece (49) facing each other when the boss (44) is closed. It is inserted into the concave peripheral surface (27) of (26). Similarly, (50) is an outward locking of the upper stage scattered and distributed as a positional relationship facing the arc outer peripheral surface (back surface) of the boss (44) in the first and second flange segments (F1) and (F2) when closing. It is a nail | claw and is defined so that elasticity can be exhibited by the split groove (51) cut from the downward direction of the circular arc outer peripheral surface (back surface).

  The upper outward latching claws (50) scattered on the open / close top flange (F) as a pair facing each other are detachably latched with upper claws receiving holes (described later) of the fuselage in the operation ring (R). By doing so, the closed state of the open / close top flange (F) is locked. As a result, there is no possibility that the open / close top flange (F) of the lifting guide (G) is detached from the mouthpiece (26) of the drinking water packaging bag (22).

  The mounting base plate (42) of the first flange segment (F1) that covers the opening top surface of the lifting guide (G) has an arc outer peripheral surface (back surface) of the boss (44) in the first flange segment (F1). ) And a circular shape having the same outer diameter as that of the boss (44), and continuously projecting from the lower end of the boss (44) in a direction directly below the boss (44) in the second flange segment (F2).

  However, the clamping piece (49) of the first and second flange segments (F1) and (F2) is at a height slightly raised from the flat upper surface of the mounting base board (42), and the upper and lower mutual gaps (x) The lower flange (not shown) of the bobbin-shaped base (26) is accepted.

  The circular needle insertion port (52) opened in the center of the mounting base board (42) is sandwiched by the sandwiching pieces (49) of the first and second flange segments (F1) (F2). The needle (N), which will be described later, is received in communication with the base (26) of the drinking water packaging bag (22). (53) is a pair of parallel floating ribs (ridges) projecting downward from the flat bottom surface of the boss (44) in the second flange segment (F2), and the first and second flange segments (F1) ( When F2) is closed, it rides on the upper surface of the mounting base plate (42) in the first flange segment (F1) stably.

  In that case, the circular mounting base board (42) of the first flange segment (F1) includes an inner wall (54) as shown in FIGS. 15, 17 and 18, and an arc outer peripheral surface (back) of the boss (44). Inverted cross-section U in a double edging reinforcement state with a continuous outer surrounding wall (55) having the same outer diameter as the surface), with the inside and outside of both surrounding walls (54) (55) opening downward A letter-shaped concave groove (56) is inserted and fitted into the upper end of the opening of the lift guide (G) from above.

  In addition, a plurality of (four in total in the figure) lower outward locking pawls (57) on the inner surrounding wall (54) bordering the circular mounting base board (42) have an overall radial symmetrical distribution type. And by the split groove (58) cut from the lower end, it is defined so as to exhibit elasticity.

  A plurality of lower outward locking claws (57) scattered on the mounting base plate (42) of the first flange segment (F1) are the upper ends of the body (31) in the lifting guide (G). The lifting guide (G) and the open / close top flange (F) are assembled and integrated by being engaged with the claw receiving hole (32) formed corresponding to the portion so as to be freely disengaged from the inside. It is.

  In the assembled state, as is apparent from the corresponding positional relationship between FIG. 10 and FIG. 14, a pair of opposed operating ring lifts arranged in a row in the upper half of the body (31) in the lift guide (G). A pair of opposed upper-stage outward locking claws (50) defined by the bosses (44) of the first and second flange segments (F1) and (F2) that form the guide groove rail (33) and the opening and closing top flange (F). ) And the phase change to an orthogonal relational state in plan view.

  A boss (44) protrudes downward from the center of the bag receiving seat (43) in the first and second flange segments (F1) and (F2), and the boss (44) of the first flange segment (F1). Since the mounting base board (42) protrudes further downward and continuously, the pair of outward locking claws (50) defined by the bosses (44) are positioned in the upper stage, and the mounting base board (42) protrudes from the mounting base. It goes without saying that the plurality of outward locking claws (57) defined in the board (42) are positioned in the lower stage.

  Further, the operation ring (R) mentioned above is made of a rigid thermoplastic resin such as polyacetal resin (trade name: Duracon) or polypropylene (PP) resin, and the above-mentioned lifting guide (G) as shown in FIGS. The boss (44) of the open / close top flange (F) and the mounting base board (42) are integrally formed in a circular ring shape that can surround the boss (44). It is desirable to give

(78) is a regulating plate piece that hangs in parallel from the boundary shoulder surface (73) by the same fixed depth (d2) as the center partition plate (77), and the first and second upper narrow passages (O1) ( Any one of (O2) (the second upper narrow passage in the example) is defined as a passage deeper than the other.

  In addition, in the upper half of the conical surface (69) divided into two equal parts by the vertical center partition plate (77), a lateral direction communicating with the first and second upper narrow passages (O1) (O2), respectively. The first and second through holes (79L) and (79R) are preferably distributed as openings having different heights or different diameters. In short, the hollow needle (N) has the above-mentioned drinking water packaging bag (22). ) And the water conduit (non-spill) (14) on the server body (10) side, and the inside thereof becomes a flow path for drinking water (W).

  Further, the bottom cap (B) of the needle (N) is made of the same AS resin as the needle (N) or other transparent or translucent hard thermoplastic resin, and has a relatively shallow cross section as shown in FIGS. Although it is integrally formed in a U-shape, a circular water pipe (non-spill) insertion port (80) that is in communication with the bottom cap receiving core tube (25) of the cup (C) is opened at the center of the bottom surface. Similarly, a ring-shaped ridge (81) for receiving and supporting the lower packing (29) is erected inwardly from the periphery of the bottom surface.

  (82) is a female screw carved in the body (83) of the bottom cap (B), and is screwed and fastened to the male screw (75) of the needle (N) from below. (84) is a large-diameter circular outward locking flange that continuously and integrally projects from the lower end of the body (83), and is formed corresponding to the lower end of the body (31) in the lifting guide (G). The inward locking claw (39) is detachably locked.

  The on-off valve (V) mentioned above is integrally formed of AS resin or other hard thermoplastic resin, and has a substantially conical saucer-shaped valve body (85) as shown in FIG. And a plurality (six in total, eight) of slide fins (87) standing in a radially symmetric distribution form from the peripheral edge of the valve body (85).

  Such an on-off valve (V) is incorporated in the upper body (70) having a small diameter of the needle (N), and the slide fin (87) swings inside the upper body (70). Without sliding, the conical valve seat (88) of the upper packing (28) is opened and closed.

  Each of the pair of upper and lower packings (28) and (29) is formed in a circular ring shape from silicone rubber or other elastic material, and the upper packing (28) is the valve body (85) of the on-off valve (V). A conical valve seat (88) that can be in close contact with the needle (N) and pressed against the boundary step surface (74) between the upper body (70) and the lower body (71) by the spacer (S) from below. The positioning is in close contact.

  On the other hand, the lower packing (29) is thicker than the thickness of the upper packing (28) (for example, about 1.5 mm) as a sealing film that bites into the watertight pipe (non-spill) (14) in a neck-tight state. (For example, about 3 mm), and is shaped like a wedge with a sharp cross section at the edge of the circular opening, and is in a state of being received from below by the bottom protrusion (81) of the bottom cap (B).

  The spacers (S) interposed between the upper and lower sides of both packings (28) and (29) are also made of AS resin or other transparent or translucent hard thermoplastic resin as shown in FIGS. It is integrally formed with an inverted U-shaped cross section, but in the center of the flat top surface that supports the upper packing (28) from below, it is in communication with the conical valve seat (88) of the upper packing (28). The conical valve seat (89) is open. The valve body (85) of the on-off valve (V) opens and closes the conical valve seat (89), but the leg of the on-off valve (V) hangs down from the valve body (85) through the conical valve seat (89). The column (86) comes into contact with the center of the top surface of the water conduit (non-spill) (14).

  On the other hand, a circular retaining flange (91) having a large diameter is continuously projected outward from the lower end of the body (90) of the spacer (S), and is screwed and fastened to the needle (N). The lower packing (29) is sandwiched from above and below by the ridge (81) of the bottom cap (B) and the presser flange (91) of the spacer (S). Reference numeral (92) denotes a plurality of reinforcing ribs (six in the illustrated example) that continuously project outward from the body (90) of the spacer (S), and are arranged in an overall radially symmetric distribution type. .

  For the inside of the upper body (70) and the lower body (71) having the stepped cylindrical shape of the needle (N), the opening / closing valve (V), the upper packing (28), the spacer (S ) And the lower packing (29) can be inserted and set, and assembled by screwing the bottom cap (B), and the bottom cap (B) can be assembled from below by the screwing force of the bottom cap (B) to the needle (N). The side packing (29) is pressed against the holding flange (91) of the spacer (S) with an appropriate strength, and further, the upper packing (28) is passed through the flat top surface of the spacer (S) with the needle ( It is also possible to adjust the pressure to an appropriate level against the boundary step surface (74) between the upper body (70) and the lower body (71) in N).

  In that case, the sealing force that the lower packing (29) bites and crimps the water guide pipe (14) is set to the conical surface (69) of the cap (26) of the drinking water packaging bag (22) and the needle (N). It is preferable to adjust and set relatively weakly (relatively) the sealing force of the sealing film (72) interposed on the fitting surface. If it does so, the reliable and stable extraction state from the server main body (10) side mentioned later like FIG. 40 will be obtained.

  After removing the bottom cap (B), the lower packing (29), the spacer (S), the upper packing (28) and the on-off valve (V) are sequentially extracted downward from the needle (N). It goes without saying that it can be disassembled and cleaned or replaced with a new one.

  In the cup receiving concave groove (12) on the top cover (11) side in the water server of the present invention, a conical top flange receiving surface (24) expanding upward and a bottom cap receiving core cylinder of the needle (N) A cup (C) having a basic U-shaped cross section including (25) is inserted and fitted from above, and a water guide pipe (non-spill) (14) is in an assembled state on the vertical center line.

  On the other hand, the opening / closing valve (V), the upper packing (28), the spacer (S), and the lower packing (29) are sequentially entered into the upper body (70) and the lower body (71) having a stepped cylindrical shape from below. ) Is inserted and set, and the needle (N) once assembled by screwing the bottom cap (B) to the lower body (71) is inserted and set further into the lifting guide (G) from above. On the other hand, the operation ring (R) is also inserted from above into the elevating guide (G) from above, and finally the open / close top flange (F) is put on the top of the opening of the elevating guide (G). By attaching, the needle (N) and the open / close top flange (F) are assembled as an assembly unit from which the needle (N) and the open / close top flange (F) are not accidentally detached from the lift guide (G).

  When using the present invention, the drinking water packaging bag (22) is inserted and set into the bag receiving holder (H), and the first opening / closing top flange (F) of the perforation adapter (A) is set. The two flange segments (F1) and (F2) are closed and sandwiched between the concave peripheral surface (27) of the mouthpiece (26) preliminarily attached to the bottom surface of the drinking water packaging bag (22), and the state Is locked with the operation ring (R) pushed up along the lifting guide (G) so that the perforation adapter (A) is not detached.

  In such a prepared state, as shown in FIG. 34, the upper claw receiving hole (67) of the operation ring (R) pushed up is the upper claw receiving claw of the first and second flange segments (F1) (F2). (50) and locked so that the first and second flange segments (F1) and (F2) are not opened.

  Further, the bottom cap (B) of the needle (N) is in an engaged state received by the inwardly engaging claw (39) on the lifting guide (G) side, and the sharp conical surface (69) of the needle (N). Is sinking to the lowest position. In addition, the on-off valve (V) in the needle (N) is closed (closed) by its own weight in close contact with the conical valve seat (88) of the upper packing (28) and the conical valve seat (89) of the spacer (S). ) State.

  Therefore, the perforation adapter (A) of the drinking water packaging bag (22) in the ready state inserted and set in the bag receiving holder (H) is placed in a downward vertical posture together with the bag receiving holder (H). As shown in FIG. 37 from 35 through FIG. 36, it is inserted and lowered into the cup (C) on the server body (10) side, so that the bottom surface of the bottom cap (B) in the needle (N) is the above cup ( FIG. 37 shows a state in which the bottom cap receiving core tube (25) on the C) side is locked and is received and supported from below.

  In this temporarily stopped state, the pedestal (86) of the on-off valve (V) comes into contact with the center of the top surface of the water conduit (non-spill) (14), so that the valve body (85) is in the upper packing (28). ) And the conical valve seat (89) of the spacer (S), and the closed state is opened (opened).

  Further, even when the perforation adapter (A) is once stopped, the large outward locking flange (84) protruding from the bottom cap (B) of the needle (N) It is still in a state of being locked with the inward locking claw (39) formed corresponding to the lower end portion.

  Then, while holding the bag receiving holder (H) of the drinking water packaging bag (22), the piercing adapter (A) of the packaging bag (22) is continuously moved through FIGS. As described above, the lift guide (G) is deeply inserted and lowered until the bottom surface of the lift guide (G) contacts the bottom surface of the cup (C).

  In this case, the drinking water packaging bag (in comparison with the fixed state in which the bottom cap (B) on the needle (N) side is received and supported by the bottom cap receiving core tube (25) on the cup (C) side is provided. 22) The elevating guide (G) attached to the bottom surface continues to descend by releasing the engagement between the inward engagement claw (39) and the outward engagement flange (84) of the bottom cap (B). Therefore, the needle (N) rises relative to this, and the mounting base plate (42) of the open / close top flange (F) is formed by the apex (cone portion) of the sharp conical surface (69). The bottom surface of the drinking water packaging bag (22) can be perforated by itself through the needle insertion opening (52) and the bobbin-shaped mouthpiece (26). In this sense, it can be said that the vertical height (h) of the bottom cap receiving core cylinder (25) defines the lifting stroke of the needle (N).

  During use of FIG. 39 in which the drinking water packaging bag (22) has been perforated, the drinking water (W) in the packaging bag (22) has a conical surface in the needle (N) as indicated by the arrow in FIG. The conical valve seat of the upper packing (28) in the upper body (70) from the first and second through holes (79L) (79R) and the first and second upper narrow passages (O1) (O2) of (69) 88) and the conical valve seat (89) of the spacer (S) in the lower body (71), and the first and second through holes (20L) (20R) and the first, It falls through the two passages (O1) and (O2), and smoothly flows into the drinking water storage tank (17) on the server body (10) side.

  In that case, the sealing film (72) adhered and integrated with the lower half (neck) of the conical surface (69) of the needle (N) is fitted into the conical surface (69) and the base (26). Since the mating surface is in a sealed state, there is no possibility that the drinking water (W) in the drinking water packaging bag (22) leaks downward from the mating surface. Moreover, since the lower packing (29) bites and seals the outer peripheral surface of the water conduit (non-spill) (14), there is no possibility that the drinking water (W) leaks from the lower end of the spacer (S).

  As the use of drinking water (W) advances, the water storage level in the drinking water storage tank (17) in the server body (10) decreases to the position shown by the solid line in FIG. 2, and only the above-mentioned constant depth (d1) When the lower end portion of the first passage (P1) cut out shallowly is exposed on the water surface first, the air in the drinking water storage tank (17) is indicated by the arrow in the figure, and the water guide pipe (non-spill) The first passage (P1) and the first passage hole (20L) of (14) and the first upper narrow passage (O1) and the first passage which are shallow passages in the needle (N) by a certain depth (d2). When it rises through the hole (79L) and flows into the inside of the drinking water packaging bag (22), and even when drinking water (W) remains in the packaging bag (22), The air is pushed down so that it flows out to the drinking water storage tank (17). Ku.

  In any case, when the drinking water (W) in the drinking water packaging bag (22) is lost, and the packaging bag (22) is replaced with a new one and loaded into the server body (10) side, From the state of FIG. 39, as shown in FIG. 40, the perforation adapter (A) of the drinking water packaging bag (22) is pulled out from the cup (C) on the server body (10) side and raised.

  Then, the valve body (85) of the on-off valve (V) existing inside the needle (N) is self-weighted, so that the conical valve seat (88) and the spacer (S) of the upper packing (28) as shown in FIG. The conical valve seat (89) is closed (closed), and the fitting surface between the conical surface (69) of the needle (N) and the base (26) of the drinking water packaging bag (22) is provided. Since it is still sealed with the sealing film (72), there is no leakage from the drinking water packaging bag (22) in the above-mentioned pulled-out state, and there is no possibility of fouling the periphery.

  Therefore, while holding the lifting guide (G) on the side of the piercing adapter (A) in the pulled-out state from the cup (C) with one hand (for example, the left hand), the open / close top flange (F) with the remaining one hand (for example, the right hand) ) Is lowered as indicated by the chain line in FIG. 40 or the solid line in FIG.

  Then, the horizontal partition plate (59) of the operating ring (R) descending along the operating guide lifting guide groove rail (33) of the lifting guide (G) is located inside the lifting guide (G). While abutting on the slide fin (87) of the needle (N), the needle (N) is lowered to the initial lowest position (see FIG. 34) as shown in FIGS. The sharp conical surface (69) of the water supply packaging bag (22) and the needle insertion opening (52) open to the base plate (42) of the opening and closing top flange (F) are pulled downward. Sunk inside the elevating guide (G).

  On the other hand, on the outside of the elevating guide (G), the locking state between the upper outward latching claw (50) in the opening and closing top flange (F) and the upper claw receiving hole (67) in the operation ring (R) is. The operation ring (R) is released by the lowering operation, and the first flange segment (F1) in the attached state in which the opening top surface of the lifting guide (G) in the open / close top flange (F) is covered is applied. On the other hand, since the second flange segment (F2) can be opened around the vertical fulcrum shaft (41), the opening operation as shown in FIG. ) Is removed from the base (26) of the packaging bag (22).

  However, the sealing force of the lower packing (29) that bites and presses against the outer peripheral surface of the water conduit (non-spill) (14) is the same as that of the cap (26) of the drinking water packaging bag (22) and the cone of the needle (N). By adjusting and setting relatively stronger than the sealing force of the sealing film (72) interposed in the mating surface with the surface (69), the needle (N) of the drilling adapter (A) is moved to the server body (10). The sharp conical surface (69) of the needle (N) falls out of the base (26) of the drinking water packaging bag (22) sooner than it is pulled out from the water conduit (non-spill) (14) on the Even if it is determined to immerse itself inside the lifting guide (G), it does not matter. Only in this case, the operation ring (R) is pulled down only to open and close the open / close top flange (F) of the lift guide (G).

  In any case, the perforation adapter (A) removed from the empty drinking water packaging bag (22) is transferred to the base (26) of the new drinking water packaging bag (22) as shown in FIGS. The opening / closing top flange (F) is closed and the operation ring (R) is pushed up, so that it can be used again, and the piercing adapter (A) can be attached to and detached from the base (26) repeatedly.

  Next, FIGS. 42 to 51 show a second embodiment of the present invention, in which the elevating guide (G) of the perforation adapter (A) is shaped into a basic cross-section inverted U shape and is cylindrical. The needle (N) can be inserted and set from below into the body (31).

  Moreover, the top flange (F) for attaching and using the lifting guide (G) of the perforation adapter (A) to the base (26) of the drinking water packaging bag (22) has a large conical saucer shape. The lifting guide (G) protrudes integrally from the upper end of the body (31) outwardly, and the lifting guide (G) such as the open / close top flange (F) shown in FIGS. 14 to 19 of the first embodiment. It is not a configuration that is assembled from the first and second flange segments (F1) and (F2) through the vertical fulcrum shaft (41) so as to be opened and closed.

  In addition, a circular needle insertion port as shown in FIGS. 42 to 45 is provided at the center of the circular bag receiving seat surface (43) of the top flange (F) that is a continuous integrated product with such a lifting guide (G). (93) is opened, and a pair of opposing key protrusions (94) protruding integrally downward from the periphery of the opening are provided on the mouthpiece (26) of the drinking water packaging bag (22) as shown in FIGS. After inserting from the correspondingly formed keyway (95), the lifting guide (G) is moved to the concave peripheral surface (27) of the base (26) by rotating it by a certain angle clockwise or counterclockwise. Can be locked so as not to fall off.

  However, if the raising / lowering guide (G) is rotated from the locked state in use and the key protrusion (94) is aligned with the key groove (95) of the base (26), The key protrusion (94) of the lifting guide (G) can be extracted from the key groove (95), and the piercing adapter (A) can be removed from the base (26) of the drinking water packaging bag (22). .

  That is, in the configuration of the second embodiment, the top flange (F) of the lifting guide (G) is not opened and closed and is not sandwiched between the cap (26) of the drinking water packaging bag (22). The operation ring (R) for opening and closing the top flange (F) as in the embodiment is unnecessary, and its installation is omitted. Further, since there is no open / close top flange (F) or operation ring (R) separate from the lifting guide (G), the lower stage outward locking as in the first embodiment is performed on the body (31) of the lifting guide (G). The receiving hole (32) of the claw (57), the lifting guide groove rail (33) for the operation ring, the outward locking claw (34), the split groove (35), the reinforcing rib (36) and the like are not provided.

  Further, the on-off valve (V) of the second embodiment incorporated in the needle (N) of the perforation adapter (A) is embodied as a ball valve made of a glass ball or the like. 50, and closes the conical valve seat (88) and the conical valve seat (89) of the spacer (S), while the ball valve is as shown in FIGS. The conical valve seat (88) of the upper packing (28) and the conical valve seat (89) of the spacer (S) are also lifted by abutting in a point contact state on the conical top surface of the water conduit (non-spill) (14). ) Is opened (opened).

  In the second embodiment of the present invention, as is apparent from FIG. 49 corresponding to FIG. 35, the key protrusion (94) of the lifting guide (G) in the perforation adapter (A) is replaced with the drinking water packaging bag (22). The hole adapter (A) is not dropped into the drinking water packaging bag (22) by being inserted through the keyway (95) of the bobbin-shaped base (26) attached to the bottom surface of the bottle and rotating by a certain angle. Keep it stopped.

  In the prepared state of FIG. 49, as in FIG. 35 of the first embodiment, the outward locking flange (84) protruding from the bottom cap (B) of the needle (N) and the lower end of the lifting guide (G) The inward locking claw (39) corresponding to the portion is locked, and the sharp conical surface (69) of the needle (N) sinks to the lowest position in the lifting guide (G). . Moreover, the open / close valve (V) in the needle (N) also closed (closed) the conical valve seat (88) of the upper packing (28) and the conical valve seat (89) of the spacer (S) by its own weight. Is in a state.

  While holding the bag receiving holder (H) of the drinking water packaging bag (22) from the above prepared state, the punching adapter (A) of the packaging bag (22) is inserted into the cup (C) on the server body (10) side. The state in which the bottom cap (B) of the needle (N) is once received by the bottom cap receiving core tube (25) of the cup (C) by being lowered is as shown in FIG. It becomes substantially the same state as FIG. 37 of one embodiment.

  In this temporarily stopped state, the on-off valve (V) makes point contact with the top surface of the conical pipe (14) so that the conical valve seat (88) and the spacer (S) of the upper packing (28) again. Ascending from the conical valve seat (89), these closed states are opened (opened). Further, the outward locking flange (84) protruding from the bottom cap (B) of the needle (N) and the inward locking claw (39) corresponding to the lower end of the lifting guide (G) are still It is in a locked state.

  Furthermore, the state in which the perforation adapter (A) is deeply inserted and lowered from the temporarily stopped state of FIG. 50 until the bottom surface of the lifting guide (G) abuts the bottom surface of the cup (C) in the server body (10) is as follows. 51, which is substantially the same as FIG. 39 in the first embodiment.

  In this deeply inserted state, the lifting guide attached to the bottom surface of the drinking water packaging bag (22) as compared with the state where the bottom cap (B) of the needle (N) is still received and fixed from below. The needle (N), which is to be relatively raised with respect to the lowering of the (G), continues to move up and down by the apex (cone portion) of the sharp conical surface (69). The bottom surface of the drinking water packaging bag (22) is perforated by itself through the needle insertion port (93) and the bobbin-shaped base (26).

  As a result, as shown by the arrow in FIG. 51, the drinking water (W) in the drinking water packaging bag (22) is distributed in the first and second through holes (70L) (70L) (open distribution in the conical surface (69) of the needle (N). 79R) and the first and second upper narrow passages (O1) (O2), the conical valve seat (88) of the upper packing (28) inside the stepped body (70) (71) and the cone of the spacer (S) It falls through the valve seat (89) and the first and second through holes (20L) (20R) and the first and second passages (P1) P2) of the water conduit (non-spill) (14), and the server body (10) side Will flow into the drinking water storage tank (17)

  In that case, the sealing film (72) adhered and integrated with the conical surface (69) of the needle (N) seals the fitting surface between the conical surface (69) and the base (26). Therefore, there is no possibility that the drinking water (W) leaks downward from the fitting surface, and the lower packing (29) bites and seals the outer peripheral surface of the water conduit (non-spill) (14). The drinking water (W) does not leak out from the lower end of the spacer (S).

  When the drinking water (W) in the drinking water packaging bag (22) eventually disappears and the packaging bag (22) is replaced with a new one, the punching adapter (A) of the drinking water packaging bag (22) from the state shown in FIG. ) And pull it up. Then, although not shown in the process, the plurality of inward locking claws (39) at the lower end of the lifting guide (G) are connected to the outward direction of the bottom cap (B) in the needle (N). 49. The hole adapter (A) can be pulled out from the cup (C) on the server body (10) side as shown in FIG. it can.
