Description

  The present invention relates to a discharge device dedicated to a soft container suitable for discharging the contents from a soft container filled with a liquid or gel-like content containing a paste-like or highly viscous liquid.

  As a flexible container filled with a sealing material for building, it has a cylindrical body part made of a soft film, a bottom plate for closing the lower end opening of the body part, and an upper ring attached to the upper end opening part of the body part Proposed and put into practical use a soft container body and a lid member plugged into the upper ring so as to close the upper end opening of the soft container body with the soft container body filled with contents. (For example, refer to Patent Document 1). When discharging the contents from the soft container, first, the sealing lid attached to the contents outlet of the lid member is opened, the virgin film adhered to the lid member is cut open, and then the contents are discharged. A nozzle is attached to the outlet, and this is loaded into the outer cylinder of a dedicated discharge gun. Next, the bottom plate of the soft container is moved to the upper ring side by the pressure piston that moves by operating the lever of the discharge gun, and the sealing material is pushed out and discharged from the nozzle while crushing the body part.

  The soft container has a relatively small capacity of, for example, 300 to 500 milliliters. However, in a soft container having a relatively large capacity of 4 to 10 liters, the soft container body has a middle portion in the height direction of the body portion of the body. A structure in which an intermediate ring is provided and the upper end opening of the flexible container body is closed with a sealing film instead of the lid member has been proposed and put into practical use (for example, see Patent Document 2).

  On the other hand, as a method of discharging the contents from the soft container, in the fuel tank of the flying body, a bag-shaped tank made of a stretchable rubber-like elastic body filled with fuel is built in the pressure container to increase the internal pressure of the pressure container. Thus, a configuration in which the bag-shaped tank is contracted to discharge the fuel in the bag-shaped tank has been proposed (see, for example, Patent Document 3).

  In a relatively small-capacity soft container as described in Patent Document 1, the contents can be discharged by manually operating the discharge gun. However, in a relatively large-capacity soft container as described in Patent Document 2, If the driving means such as a cylinder or a piston pump is not used, the contents cannot be discharged, and there is a problem that the contents discharge device becomes large. For this reason, usually, the contents of the soft container are transferred to a dedicated discharge gun little by little, but this work is very complicated.

  An object of the present invention is to enable discharge of contents with a low pressure, so that a light and inexpensive device can be used as a driving means for discharging, and a flexible container dedicated discharging device that allows easy replacement of a soft container Is to provide.

  A discharge device dedicated to a soft container according to the present invention includes a pressurized tank that accommodates a soft container, pressurized air supply means for supplying pressurized air into the pressurized tank, and a discharge hose to the pressurized tank. A discharge container dedicated to a soft container comprising a discharge gun connected to each other, wherein the soft container includes a cylindrical body part made of a soft film, a bottom plate for closing a lower end opening of the body part, and an upper end opening of the body part A soft container body having an upper ring attached to the middle part and an intermediate ring attached to a middle part of the body part in the height direction, and the upper end opening of the soft container body is filled with the contents in the soft container body. A lid attached to the upper ring so as to be closed, and the pressurized tank is capable of hermetically closing a tank body having a size capable of accommodating the soft container, and an upper end opening of the tank body, and Contents to the discharge hose A tank lid formed with a supply hole, receiving the upper ring of the soft container at the upper edge of the tank body, and in a state where the upper ring of the soft container is in airtight contact with the outer peripheral part of the bottom surface of the tank lid The soft container is accommodated and held in a pressurized tank.

  When storing the soft container in the discharge device, the upper ring of the soft container is received at the upper edge of the tank body, and the upper ring of the soft container is in an airtight contact with the outer periphery of the bottom surface of the tank lid Then, the soft container is accommodated and held in the pressurized tank. At this time, the lid material can be removed in advance before the soft container is accommodated and held in the pressurized tank, but the contents adhere to the bottom surface of the tank lid, and it is necessary to wash the tank lid when replacing the soft container. Therefore, when possible, when the soft container is accommodated and held in the pressurized tank, it is preferable that the portion of the lid facing the supply hole is cut in advance so that the soft container communicates with the supply hole. . Thus, when the pressurized tank is housed in the pressurized tank and pressurized air is supplied into the pressurized tank by the pressurized air supply means to increase the internal pressure of the pressurized tank, the softness between the upper ring and the intermediate ring is increased. The body portion of the container and the body portion of the soft container between the intermediate ring and the bottom plate are contracted and deformed, and the contents in the soft container are discharged from the discharge gun through the supply hole and the discharge hose. Then, the contents are sequentially discharged while the body portion is contracted, and the intermediate ring and the bottom plate are fitted to the upper ring, so that the contents in the soft container can be discharged almost completely. Also, with the contents almost completely discharged, the intermediate ring and the bottom plate are fitted to the upper ring, and the height of the soft container is, for example, 1/6 to 1/8 before use. Volume can be reduced until

  Thus, in this discharge device, the contents can be discharged at a relatively low pressure, so that the pressure-resistant strength of the pressurized tank can be set low, the pressurized tank can be configured to be lightweight, and the pressurized tank is manufactured. Cost can be reduced. In addition, it is possible to adopt an inexpensive one as the pressurized air supply means, and the manufacturing cost of the discharge device can be reduced overall. In addition, since the pressurized tank can be configured to be lightweight, even if it is a discharge device that accommodates and holds a relatively large-capacity soft container, an operator can carry it to carry out the content application operation and filling operation. It becomes possible. Furthermore, as the soft container, the middle part of the body part in the height direction, that is, the body part between the bottom plate and the upper ring is provided with an intermediate ring, so the middle part of the body part in the height direction is It is possible to reliably prevent a problem that the contents remain in the flat plate shape and the contents remain in the body portion below the contact portion.

  Here, a cutter for incising the lid material of the soft container can be provided in a protruding shape on the bottom surface of the tank lid so as to correspond to the supply hole. With this configuration, even if the lid is not cut by operating the cutter by hand, it is possible to automatically cut the appropriate position of the lid by simply assembling the tank lid to the tank body. Can be communicated to.

  It is also preferable to provide a seal ring that is airtightly pressed against the upper ring on the tank lid. By providing such a seal ring, it is possible to reliably prevent the pressurized air supplied into the pressurized tank from being introduced between the lid member and the tank lid and being introduced into the supply hole.

  In a preferred embodiment, a rotation restricting pin protruding outward is provided on the upper ring of the soft container, and a fitting recess is provided in the tank lid or the pressurized container main body so that the rotation restricting pin cannot be relatively rotated. is there. For example, in the case of a two-component curable sealing material, the lid material is removed and then the two components are stirred and mixed in a soft container. In the conventional method, the mixture is transferred to a small-volume discharge gun. Instead, the joints and the like were filled. However, in the present invention, after stirring and mixing in the soft container, the contents can be discharged directly from the soft container by storing and holding it in the pressurized tank. This saves the trouble of transferring contents.

  It is also a preferred embodiment to provide a safety valve in the pressurized tank. Although the discharge device of the present invention can be operated at a relatively low pressure of about 0.5 MPa, in consideration of safety, a safety valve that operates when the pressure in the pressurized tank becomes higher than a set pressure is provided. It is preferable to provide the pressure tank so as to prevent the pressure in the pressurized tank from becoming higher than the set pressure.

  Using the bottom plate of the soft container having a bottom surface portion and an outer peripheral ring portion extending downward from the outer peripheral portion of the bottom surface portion, and attaching the lower end portion of the body portion to the outer peripheral surface of the outer peripheral ring portion in an outer fitting shape This is a preferred embodiment. Although it is possible to extend the outer ring from the outer peripheral part of the bottom part to the upper side, the contents remain inside the outer ring even when the contents are discharged and the soft container is completely crushed. Thus, it is preferable that the outer peripheral ring portion extends downward from the bottom surface portion.

  According to the discharge device dedicated to the soft container according to the present invention, the contents can be discharged at a relatively low pressure, so that the pressure strength of the pressure tank can be set low, the pressure tank can be configured to be lightweight, and the pressure can be increased. The production cost of the pressure tank can be reduced. Moreover, an inexpensive device can be used as the pressurized air supply means, and the manufacturing cost of the discharge device can be reduced overall. In addition, since the pressurized tank can be configured to be lightweight, when the worker carries the pressurized tank on the back and performs the content application operation or filling operation, the burden on the operator is reduced or the content capacity is increased. Can be. Furthermore, as the soft container, the middle part of the body part in the height direction, that is, the body part between the bottom plate and the upper ring is provided with an intermediate ring, so the middle part of the body part in the height direction is It is possible to reliably prevent a problem that the contents remain in the flat plate shape and the contents remain in the body portion below the contact portion.

In a state where the gas is discharged almost completely, the intermediate ring 5 is fitted inside the upper ring 4, and the bottom plate 3 is fitted inside the intermediate ring 5, so that the content 7 remaining in the soft container 1 is reduced as much as possible. It is configured as follows.

  The lid 8 is made of the same or different film as the soft film constituting the body portion 2, and after the contents 7 are filled in the soft container body 6, the cover 8 is hermetically fused over the entire upper surface of the upper ring 4. Has been. The shape of the lid member 8 is formed in a square shape in the present embodiment, but can be formed in any shape as long as it has a size that allows the soft container body 6 to be hermetically sealed. However, as the lid member 8, in the case of an incisable film or sheet-like member, a metal sheet having an incisable thickness may be used in addition to a laminated film obtained by laminating a resin film or a metal foil with a resin film. Is possible. Further, when the soft container 1 is loaded into the discharge device 10 with the lid 8 removed, it can be formed of a molded product such as a synthetic resin material or a metal material.

Next, the configuration of the flexible container dedicated discharge device 10 will be described.
As shown in FIGS. 1 and 4 to 9, the discharge device 10 dedicated to a soft container includes a pressurized tank 11 that houses the soft container 1, and a pressurized air supply unit that supplies pressurized air into the pressurized tank 11. 12 and a discharge gun 14 connected to the pressurized tank 11 via a discharge hose 13.

Has been. In addition, the ring portion 4a of the upper ring 4 is configured to protrude upward from the tank body 15 in such a supported state. The ring member 19 and the tank body 15 can be formed as an integrally molded product. However, since the manufacturing cost increases, it is preferable that the ring member 19 and the tank body 15 be formed of separate members and fixed integrally by welding or the like. . However, as long as the ring member 19 is configured to support the upper ring 4 of the soft container 1 from below, the ring member 19 can be formed in an arbitrary shape according to the cross-sectional shape of the upper ring 4 of the soft container 1. it can.

  A cylindrical connecting portion 15f communicating with the inside of the tank main body 15 is formed at the lower end portion of the peripheral wall portion 15a of the tank main body 15 so as to protrude outward, and an air hose of the pressurized air supply means 12 is connected to the connecting portion 15f. The tank body 15 can be pressurized.

  The tank lid 16 is formed of a substantially flat disk-shaped member, and a seal surface 16a is formed on the outer peripheral portion of the lower surface of the tank lid 16 to which the outer peripheral seal ring 18 is pressed. A fitting groove 16b into which the ring portion 4a of the upper ring 4 of the soft container main body 6 supported by the fitting is fitted is formed. The inner circumferential seal ring 20 is loaded in the fitting groove 16b, and the inner circumferential seal ring 20 is attached directly to the upper end of the ring portion 4a or via the lid member 8 with the tank lid 16 attached to the tank body 15. It is configured to be indirectly pressed so that the pressurized air in the tank main body 15 can be prevented from entering the soft container main body 6 or between the lid member 8 and the tank lid 16.

  A supply hole 16c is formed in the center of the tank lid 16, and the end of the discharge hose 13 is connected to the supply hole 16c so that the contents 7 in the flexible container 1 can be supplied to the discharge gun 14. In addition, the outer peripheral portion of the upper surface of the tank lid 16 is formed with an inclined surface 16d that is lowered on the outer peripheral side. Reference numeral 21 denotes a handle for carrying the pressurized tank 11, and reference numeral 28 denotes a safety valve for preventing the internal pressure of the pressurized tank 11 from becoming higher than a set pressure.

  A cutter 22 is formed on the bottom surface of the tank lid 16 so as to protrude downward along the supply hole 16 c, and the lid material 8 of the soft container 1 is cut by the cutter 22 with the tank lid 16 attached to the tank body 15. It is configured to be. As the cutter 22, it is possible to adopt an arbitrary configuration, but the cutter 22 is configured such that a part of the cut lid member 8 is cut off and does not flow into the discharge hose side together with the contents 7. It is preferable to do. For example, like the cutter 22A shown in FIG. 7, a ring-shaped substrate portion 22a is provided on the bottom surface of the tank lid 16 along the supply hole 16c, and the substrate portion 22a has a partial cylindrical shape, a partial rectangular tube shape, and a lower end. What stood the cutter main body 22b inclined with respect to the board | substrate part 22a can be used. Further, as in the cutter 22B shown in FIG. 8, it is also possible to employ a plate-shaped two cutter main bodies 22c fixed to the substrate portion 22a in a cross shape. In the cutter 22B, the number of cutter main bodies 22c can be set arbitrarily. However, when the cutter 22 is provided in a projecting manner on the bottom surface of the tank lid 16 in this way, the bottom surface portion 3a of the bottom plate 3 of the soft container 1 after use does not adhere to the bottom surface of the tank lid 16 and remains in the soft container 1. Since the amount of the contents 7 to be increased increases, a recess for accommodating the cutter 22 may be formed in the bottom surface portion 3 a of the bottom plate 3 facing the cutter 22. Further, the cutter 22 is omitted, a guide line for incision is printed at a position facing the supply hole 16c in the lid member 8, and the cutter is manually operated along the guide line etc. It is also possible to configure the material 8 to be incised.

  The fixing bracket 17 will be described. Three partial arc-shaped sandwiching members 23 that can be arranged in an outer fitting manner are provided on the outer peripheral portion of the flange portion 15c of the tank body 15 and the tank lid 16, and these three sandwiching members 23 are connected in series. Two sets of sandwiching members 23 arranged adjacent to each other when being arranged in a shape are connected to each other by connecting pins 24 so as to be rotatable. A connecting portion 23 a that protrudes outward is formed at an end portion of the holding member 23 that is disposed on both sides of the three holding members 23, and a screw rod 25 is a pin member at the connecting portion 23 a of one of the holding members 23. 26, an engaging groove 23b in which the screw rod 25 can be engaged is formed in the connecting portion 23a of the other holding member 23, and the screw rod 25 can be manually rotated. A nut 27 is screwed. On the inner peripheral side of the clamping member 23, a trapezoidal shape that can be externally fitted to the outer peripheral part of the tank cover 16 and the flange part 15 c of the tank main body 15 that are superposed by placing the tank cover 16 on the tank main body 15. A fitting groove 23c is formed.

  When the tank lid 16 is fixed to the tank body 15, the tank lid 16 is placed concentrically on the tank body 15, and the outer peripheral portion of the tank lid 16 and the flange portion 15 c of the tank body 15 The three clamping members 23 are wound around the outer peripheral portion of the tank lid 16 and the flange portion 15c of the tank body 15 so as to be fitted into the fitting groove 23c, and the screw rod 25 is engaged with the engaging groove 23b. The operation nut 27 is fastened to the screw rod 25, and the inclined surface 15e of the tank body 15 and the inclined surface 16d of the tank lid 16 are pressed toward each other by the inner surface of the fitting groove 23c of the clamping member 23, The tank lid 16 is tightly fixed to 15. However, as long as the tank lid 16 can be in close contact with the tank body 15, a fixing structure or a fixing means other than the fixing bracket 17 described above can be employed.

  As the pressurized air supply means 12, for example, a device capable of supplying pressurized air of 0.5 MPa can be employed. Electric type pressurized air supply means that pressurizes by driving the compressor with a motor can be adopted, pressurized air supply means consisting of a manual or foot-operated air pump, or manual or foot-operated air pump and air tank It is also possible to employ a pressurized air supply means comprising a combination of

  The discharge gun 14 includes a valve 31 that can switch the content 7 from the discharge hose 13 between a discharge state and a stop state by operating the operation lever 30 and a nozzle 32 that discharges the content 7. It is a thing of composition.

  When the contents 7 filled in the soft container 1 are discharged using the discharge device 10 dedicated to the soft container, first, the flange portion 4b and the handle portion 4c are provided with the flange groove portion 19a and the handle groove portion 19b. The flexible container 1 is fitted and attached to the tank body 15 so as to be fitted and supported on the tank body, and then the tank lid 16 is placed concentrically on the tank body 15, and the tank lid is attached to the tank body 15 by the fixing bracket 17. 16 is tightly fixed. In this state, the outer peripheral seal ring 18 is pressed against the seal surface 16a, the tank lid 16 is airtightly fixed to the tank body 15, and the upper surface of the ring portion 4a of the upper ring 4 has the lid material 8 interposed therebetween. Is pressed against the inner peripheral seal ring 20 to reliably prevent the intrusion of pressurized air between the tank lid 16 and the lid member 8, and the lid member 8 is opened by the cutter 22, so that the soft container 1 is used for discharge. It communicates with the hose 13.

  Thus, in a state where the flexible container 1 is assembled to the pressurized tank 11, pressurized air is supplied into the pressurized tank 11 by the pressurized air supply means 12, and the pressurized tank 11 is pressurized to a certain pressure. As shown in FIG. 9, the operation lever 30 is operated, and the contents 7 are sequentially discharged from the discharge gun 14 while the body portion 2 of the soft container 1 is contracted and deformed by the pressure of the pressurized air.

  As described above, in the exclusive discharge device 10 for the soft container, the body portion 2 of the soft container 1 can be sequentially contracted by the pressurized air to discharge the content 7, so that a large amount of waste after the content 7 is taken out can be discharged. Volume reduction is possible. Moreover, since the soft container 1 is contracted by the pressurized air, the contents 7 can be discharged only by pressurizing at a relatively low pressure, and it is possible to adopt a lightweight and inexpensive one as the pressurized air supply means 12. . Further, since the soft container 1 can be loaded into the pressurized tank 11 with the lid 8 attached, the contents 7 can be prevented from adhering to the bottom surface of the tank lid 16, and the bottom surface of the tank lid 16 can be cleaned. Since it becomes unnecessary, the exchange work of the soft container 1 becomes easy. In addition, since the content 7 used last time is filled in the end portion of the discharge hose 13 in the supply hole 16c of the tank lid 16, when the soft container 1 is replaced, the discharge route of the content 7 is changed. It is possible to almost completely prevent air from remaining.

  When the soft container 1 filled with a two-component curable sealing material is used as the soft container 1, the cover material 8 is peeled and removed, and then the soft container 1 is set in a dedicated stirring device. After the two liquids are stirred and mixed in 1, the soft container 1 is loaded into the tank main body 15 and the tank lid 16 is fixed to the tank main body 15 with the fixing bracket 17 in the same manner as described above. The pressurized air is supplied into 11 and the contents 7 are discharged from the nozzle 32 of the discharge gun 14. For this reason, the contents 7 stirred and mixed in the large-capacity soft container 1 can be directly discharged from the discharge gun 14 without being transferred to a small-capacity dedicated discharge gun as in the prior art. Therefore, the workability can be greatly improved.
