Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1 of the Invention
FIG. 1 is a front view of a fluid pouch showing an example of a fluid container according to Embodiment 1 of the present invention. In this fluid pouch 1, two resin sheet-like materials are overlapped, and a portion of the joining margin 3 provided around the resin pouch 1 is joined so as not to be peeled off by heat welding or the like. A bag-like storage chamber 4 is provided. A cylindrical spout mounting portion 5 that communicates with the storage chamber 4 is also formed. The shape of the spout mounting portion 5 is a conical cylinder shape whose diameter decreases toward the storage chamber 4.

  At the time of manufacturing the fluid pouch 1, the tip of the spout mounting part 5 is closed by the joining allowance 3. Of the four sides of the joint allowance 3, for example, the other three sides excluding the lower side are joined first, and then liquids such as liquid pharmaceuticals, fluid foods and beverages are filled in the storage chamber 4, and finally The lower side of the joint allowance 3 is joined.

  The resin sheet-like material forming the fluid pouch 1 has a straight-cut property that can be torn only in one direction, and the tearing direction T coincides with the direction in which the spout attachment portion 5 is opened. That is, the opening direction of the spout attachment portion 5 is the left-right direction toward FIG. 1, and the tearing direction T of the fluid pouch 1 is also the same direction. A cut line 7 for cutting the tip of the spout mounting portion 5 is displayed parallel to the upper edge of the fluid pouch 1, and a cut point serving as a starting point of the cut line 7 is displayed on one side of the fluid pouch 1. 8 is provided in a slit shape, for example.

  For this reason, by tearing the fluid pouch 1 from the cut point 8, the fluid pouch 1 is cut along the cut line 7, and the tip of the spout mounting portion 5 is opened as shown in FIG. A hanging hole 9 for suspending the fluid pouch 1 is formed in the vicinity of the lower edge of the fluid pouch 1.

  3 to 9 show the configuration of the spout 11 that is detachably mounted on the spout mounting portion 5 of the fluid pouch 1.

  The spout 11 is mainly composed of a substantially cylindrical spout body 12 inserted into the spout mounting portion 5. The spout main body 12 is made of, for example, a transparent and tough polycarbonate resin, and a spout passage 14 is formed along the axis. The extraction passage 14 is a straight line that communicates the storage chamber 4 of the fluid pouch 1 with the outside.

  A lever mounting boss 16 having an enlarged outer diameter is formed in the middle portion of the spout main body 12, and the upper portion is a nozzle portion 17 and the lower portion is an insertion portion 18. The nozzle portion 17 has a tapered conical cylinder shape, for example, and the insertion portion 18 has a cylindrical shape with a constant outer diameter.

  Male screws 19 and 20 are formed at the root portion of the nozzle portion 17 and the lower end portion of the insertion portion 18, respectively. A cap 22 is screwed onto the male screw 19 to seal the outer end of the dispensing passage 14. The male screw 20 has a basic outer diameter smaller than that of the insertion portion 18, thereby forming a stepped portion 23 (see FIG. 5).

  Further, two screw holes 24 that are opposed to each other in the radial direction are formed on the side surface of the lever mounting boss 16. These screw holes 24 are not through holes and do not communicate with the extraction passage 14.

  Further, the spout main body 12 is provided with a seal bush 26 and a diameter expansion mechanism portion 28 as a sealing member constituting a diameter expansion seal means. The diameter-expansion mechanism 28 includes, for example, a washer 30, a pressing bush 31, an insert head 32, a cam lever 33, a reinforcing clamp 34, and two screws 35.

  The seal bush 26 which is a sealing member is formed in a cylindrical shape by a flexible elastic material such as silicon rubber. The washer 30 is made of metal, and the pressing bush 31 and the insert head 32 are formed of a hard resin such as a polycarbonate resin, like the spout main body 12. The inner diameter of the seal bush 26, washer 30, and pressing bush 31 is set such that the inner diameter of the seal bush 26, the washer 30 and the pressing bush 31 can be smoothly and densely attached to the insertion portion 18 of the spout main body 12. Both are set to the same dimensions.

  As shown in FIGS. 5, 8, and 9, the insert head 32 has a conical shape in which the base portion 37 is reduced in diameter downward, and the outer diameter of the upper end of the base portion 37 is the seal bush 26, washer 30, It is equal to the outer diameter of the pressing bush 31. The base 37 is provided with a female screw 38, an opening 39, and a tongue-shaped guide plate 40. Since the guide plate 40 is formed in a substantially U shape straddling the opening 39, it does not close the opening 39. In addition, an edge portion 41 having a thin wedge shape is formed at the tip of the guide plate 40.

  A washer 30, a pressing bush 31, and a seal bush 26 are sequentially attached to the insertion portion 18 of the spout body 12, and finally, the female screw 38 of the insert head 32 is screwed to the male screw 20, and the insert head 32 is stepped. It is tightened until it hits part 23. Even when the insert head 32 is screwed into the male screw 20, the pouring passage 14 of the spout main body 12 is opened downward through the opening 39 of the insert head 32.

  When the insert head 32 is fastened to the spout main body 12, the washer 30, the pressing bush 31, and the seal bush 26 cannot move in the axial direction of the spout main body 12. Note that the pressing bush 31 serves as a side pressing member with the seal bush 26 interposed therebetween, and the insert head 32 serves as a fixed-side pressing member.

  On the other hand, as shown in FIG. 5, the cam lever 33 includes a base portion 44 and a lever portion 45 extending from the base portion 44 in a substantially L shape, and a screw hole 46 is formed in the base portion 44. An open cam surface 47a separated by a dimension X from the center of the hole 46 and a closing cam surface 47b separated by a dimension Y from the center of the screw hole 46 are formed at a relative angle of 90 degrees. The relationship between the dimension X and the dimension Y is X <Y. The reinforcing clamp 34 is substantially U-shaped and has screw holes 49 on both sides.

  As shown in FIG. 6, the base 44 of the cam lever 33 is applied to the lever mounting boss 16 of the spout main body 12, a reinforcing clamp 34 is provided so as to sandwich it from the outside, and a screw 35 is tightened from the outside. It is. The screw 35 passes through the screw hole 49 of the reinforcing clamp 34 and the screw hole 46 of the cam lever 33 and is fastened to the screw hole 24 of the lever mounting boss 16. The female screw to which the screw 35 is fastened may be formed in the screw hole 24 of the lever mounting boss 16 or the screw hole 49 of the reinforcing clamp 34. If a female screw is formed in the screw hole 49 of the reinforcing clamp 34, which is a metal part, the strength of the female screw is greater than if a female screw is formed in the screw hole 24 of the lever mounting boss 16 (spout port body 12), which is a resin part. Can be improved.

  The cam lever 33 pivots 90 degrees between the open position 33a shown in FIG. 3 and the closed position 33b shown in FIG. 4 with the screw 35 as a support shaft, and the open cam surface 47a of the cam lever 33 is at the open position 33a. The closing cam surface 47b contacts the washer 30 at the closing position 33b.

  When the cam lever 33 is in the open position 33a, no pressing force acts from the open cam surface 47a to the washer 30, but when the cam lever 33 rotates from the open position 33a to the closed position 33b, the cam is released from the shaft center of the screw 35. Since the dimension Y to the closing cam surface 47b is larger than the dimension X to the surface 47a, the washer 30 is pressed by an amount obtained by subtracting the dimension X from the dimension Y, and the washer 30 and the pressing bush 31 are inserted into the insert head 32. Move to the side.

  On the other hand, since the insert head 32 is fixed to the spout body 12, the seal bush 26 sandwiched between the pressing bush 31 and the insert head 32 is compressed and deformed in the axial direction, and the outer diameter of the seal bush 26 is increased. Diameter. At this time, the lever portion 45 of the cam lever 33 rotated to the closing position 33 b is parallel to the axial direction of the spout main body 12 and is located in the vicinity of the spout main body 12.

  As shown in FIG. 10, the spout 11 is inserted into the spout mounting portion 5 of the fluid pouch 1 with the cam lever 33 placed at the open position 33a. At this time, the guide plate 40 (edge portion 41) provided at the tip of the insert head 32 is inserted between the two resin sheet-like materials forming the fluid pouch 1 so that the spout 11 is Can be easily inserted into the spout mounting portion 5. As described above, the guide plate 40 functions as a guide portion that facilitates insertion of the spout 11 into the spout mounting portion 5.

  As described above, the base portion 37 of the insert head 32 has a conical shape that is reduced in diameter toward the accommodation chamber 4 side of the fluid pouch 1, and the shape of the spout attachment portion 5 is also reduced in diameter toward the accommodation chamber 4. It is a conical cylinder shape. As shown in FIG. 10, the spout 11 is formed by the male tapered portion 51 that forms the outer peripheral surface of the base 37 of the insert head 32 and the female tapered portion 52 that forms the inner peripheral surface of the spout mounting portion 5. An insertion depth determining means for inserting the lens 5 at an appropriate depth is configured.

  That is, the maximum outer diameter D1 of the male taper portion 51 is set to be larger than the minimum inner diameter D2 of the female taper portion 52, and the position where the male taper portion 51 is stuck in the female taper portion 52 is the proper position of the spout 11 The dimensions of the maximum outer diameter D1 and the minimum inner diameter D2 are set in advance so as to obtain an appropriate insertion depth. Thereby, it is prevented that the spout 11 is inserted too deeply or insufficiently inserted into the spout mounting part 5, and the detachability of the spout 11 can be improved.

  Moreover, when the spout 11 is inserted into the spout mounting portion 5, the spout 11 is wedged to the spout mounting portion 5 by fitting the male tapered portion 51 and the female tapered portion 52 slightly stronger. Therefore, the spout 11 and the spout mounting portion 5 can be prevented from being detached when the cam lever 33, which will be described later, is rotated. This greatly improves the workability of mounting the spout 11. Can be better.

  Then, as shown in FIG. 11, when the cam lever 33 of the spout 11 is rotated to the closing position 33b, a pressing force is applied to the washer 30 from the closing cam surface 47b of the cam lever 33 as described above. Is applied to the seal bush 26 via the pressing bush 31, and the seal bush 26 is elastically deformed in the axial direction inside the spout mounting portion 5 and its outer diameter is increased. For this reason, the outer peripheral surface of the seal bush 26 is pressed against the inner peripheral surface of the spout mounting portion 5, whereby the space between the spout 11 and the spout mounting portion 5 is sealed in a liquid-tight manner. It is fixed to the spout mounting part 5.

  The strength of the spout mounting portion 5 and the amount of diameter expansion of the seal bush 26 are such that when the seal bush 26 is expanded, the spout mounting portion 5 is torn or the joint allowance 3 is peeled off on both sides of the spout mounting portion 5. It is necessary to set appropriately so as not to occur. In FIG. 11, the axial direction of the rotating shaft (screw 35) of the cam lever 33 is orthogonal to the surface direction of the fluid pouch 1, but this is to make it easy to see the figure. It is better to make the open coaxial direction parallel to the surface direction of the fluid pouch 1 so that the cam lever 33 rotated to the closing position 33 b does not interfere with the fluid pouch 1.

  Thus, the fluid-like contents stored in the storage chamber 4 of the fluid pouch 1 to which the spout 11 is attached are poured out from the spout passage 14 of the spout 11 through the nozzle portion 17 to the outside. In addition, by attaching the cap 22 to the nozzle portion 17, the outflow of the contents can be stopped, and the inside of the fluid pouch 1 can be sealed from the outside to maintain hygiene.

  When the spout 11 is removed from the fluid pouch 1 after use, the insert head 32 is loosened and removed from the spout main body 12, the seal bush 26, the pressure bush 31 and the washer 30 are pulled out, and the screw is loosened to remove the cam lever. By removing 33 and the reinforcing clamp 34, it can be easily disassembled and cleaned, and the hygienic condition can be kept good.

  As described above, according to the fluid pouch 1 and the spout 11, the spout 11 can be attached to and detached from the fluid pouch 1 while ensuring good liquid tightness and detachability with a very simple structure. Thus, without increasing the manufacturing cost of the fluid pouch 1, a special shape can be imparted to the nozzle portion 17 of the spout 11 and it can be adapted to a specialized field at a medical site or the like. That is, the shape of the nozzle portion 17 is not limited to the shape of the present embodiment, and other shapes may be used.

Further, the diameter-expansion mechanism 28 is operated by the cam lever 33, and insertion depth determining means for inserting the spout 11 into the spout mounting portion 5 at an appropriate depth (male tapered portion 51 and female tapered portion). 52), a guide plate 40 for facilitating insertion into the spout mounting portion 5 is provided in the spout 11 (insert head 32), and a resin sheet material for forming the fluid pouch 1 is provided. Having a straight-cut property that can be torn only in one direction, making the opening direction of the spout attachment portion 5 coincident with the tearing direction T of the resin sheet-like material, making it easier to open the spout attachment portion 5 etc. Therefore, the detachability of the spout 11 with respect to the spout mounting part 5 can be further improved.
[Embodiment 2 of the Invention]
FIG. 12 is a front view showing a fluid pouch and a spout according to Embodiment 2 of the present invention. Here, the configuration of the fluid pouch 1 is the same as that of the first embodiment, and the spout 61 is the same as that of the first embodiment except for the configuration of the spout main body 62 and the diameter expansion mechanism 63. These parts are denoted by the same reference numerals and description thereof is omitted.

  The diameter increasing mechanism 63 of the spout 61 includes a male screw 64 formed on the outer peripheral surface of the resin spout main body 62, a resin pressing bush 65 screwed into the male screw 64, and a metal A washer 30 and a resin-made insert head 32 screwed to the lower end of the spout main body 62 are provided. The seal bush 26 which is a sealing member, the washer 30 and the insert head 32 are the same as the members of the same reference numerals shown in the first embodiment.

  The pressing bush 65 is integrally provided with a dial portion 66 having a large outer diameter, and the pressing bush 65 can be moved in the axial direction of the spout main body 62 by rotating the dial portion 66 by hand. Here, the pressing bush 65 serves as a movable pressing member with the seal bush 26 interposed therebetween, and the insert head 32 serves as a fixed pressing member.

  As shown in FIG. 12, the spout 61 is inserted into the spout mounting part 5 of the fluid pouch 1 to an appropriate depth, and while holding the seal bush 26 from above the spout mounting part 5 with one hand, When the dial portion 66 is rotated with the other hand and the pressing bush 65 is moved to the seal bush 26 side, the seal bush 26 is compressed and deformed in the axial direction and the outer diameter is expanded as in the case of the first embodiment. The outer peripheral surface of the seal bush 26 is brought into pressure contact with the inner peripheral surface of the spout mounting portion 5 so that the space between the spout 61 and the spout mounting portion 5 is liquid-tightly sealed. 5 (see FIG. 13).

  Since a metal washer 30 is interposed between the resin-made pressing bush 65 and the seal bush 26 made of an elastic material such as silicon rubber, friction force due to the viscosity of the sealing bush 26 acts on the pressing bush 65 as a brake. This prevents the pressing bush 65 from rotating smoothly. The upper end portion of the male screw 64 is formed to have a length that sufficiently protrudes from the upper surface of the pressing bush 65, and the cap 22 shown in FIGS. 3 and 4 is screwed into the protruding portion of the male screw 64 as it is. Thus, the outer end of the extraction passage 14 can be sealed.

By configuring such a diameter expansion mechanism 63, all the parts other than the washer 30 are made of non-metal, and the manufacturing cost of the entire spout 61 is significantly lower than that of the spout 11 of the first embodiment. The disassembly, assembly workability, and cleanability of the spout 61 can be greatly improved.
Embodiment 3 of the Invention
FIG. 14 is a front view showing a fluid pouch and a spout according to Embodiment 3 of the present invention. Here, the spout 71 has the same configuration as that of the first embodiment except for the pressing bush 72, and the fluid pouch 73 has the same configuration as that of the first embodiment except for the spout mounting portion 74. Since these are the same, those portions are denoted by the same reference numerals and description thereof is omitted.

  The pressing bush 72 of the spout 71 is provided with a protruding stopper 75 serving as an insertion depth determining means having a form different from that of the first embodiment. The protruding stopper 75 is formed in, for example, a thin disk-like flange shape. On the other hand, the spout mounting portion 74 of the fluid pouch 73 is not a conical cylinder having a diameter reduced toward the storage chamber 4 as the spout mounting portion 5 in the first embodiment, but a cylindrical shape having a constant inner diameter. ing.

  The position of the protruding stopper 75 of the spout 71 is positioned so as to abut the tip of the spout mounting portion 74 when the spout 71 is inserted into the spout mounting portion 74 at an appropriate depth. The shape of the protruding stopper 75 does not have to be a disk shape, and other shapes such as a protruding shape and a tongue shape are also conceivable.

  In the case of the first embodiment, the spout 71 is inserted into the spout mounting portion 74 until the protruding stopper 75 contacts the tip of the spout mounting portion 74, and the cam lever 33 is rotated to the closed position 33b at this position. In the same manner as described above, the pressing bush 72 presses the seal bush 26 in the axial direction to compress and deform it, thereby expanding the outer diameter of the seal bush 26 and pressing the outer peripheral surface thereof against the inner peripheral surface of the spout mounting part 74 The space between the spout 71 and the spout mounting portion 74 is sealed in a liquid-tight manner, and the spout 71 is fixed to the spout mounting portion 74.

As a result, the spout 71 can be inserted into the spout mounting portion 74 at an appropriate depth, and the detachability of the spout 71 can be improved.

However, in the spout attachment portion 83, the center line 83a is inclined with respect to the center line 81a, and the center line 83a flows. It is almost along the diagonal of the body pouch 81. As described above, the positions and directions of the spout mounting portions 82 and 83 can be set as appropriate depending on the usage state of the fluid pouch 81.
Embodiment 5 of the Invention
FIG. 16 is a front view showing a fluid pouch according to Embodiment 5 of the present invention. In this fluid pouch 91, two resin sheet-like materials are not overlapped and joined as in the fluid pouches 1, 73, 81 described above, but one resin sheet-like material is folded in two. Thus, the remaining three pieces excluding the bent portion 92 are used as the joining allowance 93 to form the accommodation chamber 94. A spout mounting portion 95 is provided at the upper end of the bent portion 92.

  According to the fluid pouch 91 formed in this way, since the joining margin 93 of the resin sheet-like material exists only on one side of the spout mounting part 95, when the spouts 11, 61, 71 are attached, By expanding the diameter of the seal bush 26, it is possible to reduce the possibility that the joint allowance 93 is peeled off and to increase the strength reliability of the fluid pouch 91.

  In the first to fifth embodiments, the fluid pouches 1, 73, 81, 91 are shown as examples of the fluid container. However, the fluid pouches are not limited to the pouch shape, and other forms of flow such as a bottle shape or a can shape are also used. The aforementioned outlets 11, 61, 71 may be attached to the body container.

  Further, even in the case of a fluid container of another shape such as a bottle shape or a can shape, a female taper portion is provided in the spout attachment portion, and an insertion depth determining means is provided together with the male taper portion 51 provided on the spout 11 or 61 side. Can be configured.
