Description

Content taking-out device for heavy packaging bag

Technical Field

The present invention relates to a content take-out device for a refill bag, which can easily take out a flowable content such as a shampoo bag, a rinse bag, a detergent bag, or the like from the refill bag.

Background

A refill bag such as a shampoo pack for refill is provided with a take-out port which can be cut out and a take-out port which is closed by a screw cap. In general, the outlet is opened, and the contents in the pack are transferred to a shampoo container or the like for use. Japanese patent application laid-open No. 2002-142851 describes an apparatus that can be used by directly taking out the contents from a refill bag without transferring the contents to a shampoo container or the like. In general, such a device is configured such that a bag such as a refill bag is housed in a container or a support member in an upright state, a suction tube of a pump is inserted into the bag through a discharge port formed in an upper portion of the bag, and an operation button of the pump is moved up and down to push out the content sucked out of the bag from a nozzle of the pump. Therefore, the shampoo or the like in the bag cannot be completely taken out to the end, and the pressing force when the operation button is pressed is transmitted to the floor on which the container is placed or the wall on which the support member is mounted, so that it is necessary to firmly hold the shampoo or the like on the wall or the like. Further, if the container is turned over or the support member is detached from the wall by the above-mentioned pressing force, the contents may overflow from the outlet, or air or water may enter the bag through the inlet to deteriorate the contents, or the initial flavor of the detergent may not be maintained. Further, Japanese patent application laid-open No. 2002-104546 discloses a device for hanging a bag and taking out the contents from the bottom of the bag. However, this type of device also has the same disadvantage as described above because the bottom of the bag is cut off and the pump is attached by the wall surface or the like which is responsible for the pressing force when the button of the pump is pressed.

Further, as shown in, for example, japanese patent application laid-open No. 47-39233, a pump for taking out contents from a container is generally configured such that the contents in a storage space of the pump are pressurized by a pressing operation and taken out from a nozzle, and the contents are sucked from the container into the storage space through an inlet side valve by a suction action at the time of restoration. In order to produce such an action, the operation button is pressed to close the inlet-side valve and open the outlet-side valve, and the operation button is returned to open the inlet-side valve and close the outlet-side valve. Such an interlocking operation is performed by pressurizing or depressurizing the space in which the content is stored, but since the space is small and the force for pressurizing the content is weak, there is a case where the valve on the inlet side is not completely closed when the content is taken out, or a time difference is required until the closing, and the content returns into the bag from the inlet during this time, and cannot be sufficiently discharged from the outlet side. Further, if not used for a long period of time, the contents such as shampoo may solidify in the outlet-side valve portion, and the opening may be closed.

Disclosure of Invention

The object of the present invention is to provide a content take-out device which can take out the content through a normal take-out port formed in a bag without providing a special notch in the refill bag such as a refill shampoo pack as described above, and can reliably take out the content to the last refill bag without causing deterioration or overflow of the content.

According to the present invention, there is provided a content taking-out device for a heavy pouch, comprising a holding member for holding the heavy pouch with a taking-out port directed downward, and a pump attached to the taking-out port of the pouch; the pump is provided with: a pump body having a substantially cylindrical housing space formed therein, the housing space having an inlet opening and an outlet opening; an inlet side valve which is communicated with the outlet and opens and closes the inlet opening so that the contents can be taken from the bag into the storage space; an outlet side valve for opening and closing the outlet opening to discharge the content in the storage space; a nozzle formed downward to communicate with the outlet-side valve; and a main shaft which is movably provided in an axial direction of the pump body so as to face the main shaft, and which is capable of pressurizing the storage space and taking out the content through the outlet-side valve.

Further, according to the present invention, there is provided the content take-out apparatus for a heavy package bag, wherein the inlet-side valve is a ball valve having a ball on a side of the storage space, the outlet-side valve is a ball valve having a ball on an outside of the storage space, and the main shaft is provided with an inclined surface which presses the ball of the inlet-side valve so that the ball comes into close contact with the inlet opening to close the inlet-side valve when the main shaft moves in the approaching direction.

Further, according to the present invention, there is provided a content taking-out device for a heavy pouch, comprising a holding member for holding the heavy pouch with the taking-out port directed downward, and a pump attached to the taking-out port of the pouch; the pump is provided with: a pump body formed with a housing space having an inlet opening and an outlet opening; an inlet side valve which is communicated with the outlet and opens and closes the inlet opening so that the contents can be taken from the bag into the storage space; an outlet side valve for opening and closing the outlet opening to discharge the content in the storage space; a nozzle formed downward to communicate with the outlet-side valve; and a pump wall body made of a soft material that can contract and return so as to be able to take out the content from the nozzle by pressurizing the storage space.

According to the present invention, the apparatus for taking out contents of a refill bag comprises an insertion fastener attached to a take-out port of the bag; the insertion-fastening member is provided with: an insertion tube inserted into the inlet and having an elastic contact member and a metal locking piece on the outer surface; and a clip which is pressure-fitted to the insertion tube so that the bag body is pressed against the locking piece when the insertion tube is inserted into the ejection port, and which closes the opening of the bag by the adhesion member. Further, as the holding member for holding the bag, a holding member for directly holding a part of the bag or a holding member for hanging the bag by being put in a storage box is provided.

The present invention is configured as described above, and includes a holding member that holds a bag with an outlet facing downward, and a pump attached to the outlet of the bag, and can pressurize the storage space by providing a main shaft that moves in the axial direction of the pump body in a state where the main shaft faces both ends of the pump body that forms the substantially cylindrical storage space, or can pressurize the storage space formed by the pump body by forming the wall of the pump body with a soft material that can contract and return, and therefore, the storage space can be pressurized from both sides to take out the contents from the nozzle. Therefore, the outlet usually provided in the conventional bag can be used without cutting off the bottom of the bag, and the contents do not spill out, deteriorate, or the perfume does not escape. Further, the contents can be easily taken out only by holding the spindles disposed in an opposed state from both sides and moving them in a direction of approaching them, or by holding the pump wall body formed of a soft material, and the contents in the bag can be completely taken out by a vacuum suction action. Further, since the load at the time of operation does not directly act on the holding member, the bag does not fall down.

Further, when the spindle is moved to close the inlet-side valve as described above, the inclined surface is formed at the tip of the spindle so that the ball of the inlet-side valve is in close contact with the inlet opening, and therefore, when the spindle is operated, the ball is directly moved to directly block the inlet opening, and the contents can be prevented from being returned into the bag. Therefore, the outlet-side valve of the outlet opening is reliably opened, and the contents can be directly taken out. If the pump wall is made of a soft material, the outlet-side valve can be opened simply by holding the body, and the contents can be taken out easily. Further, if a knob is provided on the valve shaft of the valve which is in close contact with the valve seat of the outlet side valve, even if the contents such as shampoo or the like are solidified in the outlet side valve to close the valve, the knob is pulled to forcibly open the valve and take out the contents.

As described above, as a normal outlet provided in a bag, a screw cap outlet and a projection-like outlet having a cutting line that can be cut off have been known. In the case of a cap, a locking cap having the same screw portion may be provided on the pump body to connect the pump. In the case of a protruding outlet, the contents do not overflow if the insertion fastener is inserted into the cut outlet and a nut having a threaded portion is screwed to the insertion fastener to connect the pump. If an elastic sealing member and a metal locking piece are provided on an insertion tube of the insertion fastener and the bag body is pressed by a clip, the bag can be reliably held so that the bag does not fall even if the bag is a heavy bag such as a shampoo bag, and leakage can be securely prevented.

Detailed Description

Fig. 1 and 2 show an embodiment of the present invention, and the apparatus of the present invention includes a holding member 3 for holding a heavy bag 1 with the outlet 2 directed downward, and a pump 4 attached to the outlet 2 of the bag 1. In this embodiment, a heavy bag in which a screw cap (not shown) is screwed to the outlet is shown, and the pump is attached to the outlet 2 by removing the cap. In the embodiment shown in fig. 1, the holding member 3 is a clamp 6 hooked on a hook 5 fixed to a wall by a suction cup or the like, and the bag is hung downward with its bottom and upper portions held therebetween in the drawing. In the embodiment shown in fig. 2, the receptacle 7 is shown with the pouch hanging downwards. As the clamp 6, an appropriate member can be used. Since the surface of the bag such as a refill shampoo bag is easily slid and the weight is also large, a holder having a large holding force is preferable. Instead of the hook, a bar-shaped hanger (not shown) may be provided, and the holding member may be hung on the hanger.

Figures 3, 4 show a clamp preferably used in the present invention. The holder body 8 of the holder 6 has a hooking hole 9 for hooking on the hook 5 at the upper side. In the case of being hung on a rod-shaped hanger (not shown) as described above, a hook-shaped hanging piece (not shown) may be formed on the holder body. Inclined surfaces 10 are formed on the inner surface of the holder body 8 in an opposed state, and insertion ports 11 opened on the lower surface and the side surface are provided. A plurality of rollers which are in rotatable contact are formed on the inclined surface facing the insertion port 11 in the axial direction, and in the figure, roller groups 13 and 14 in which two rollers 12a and 12b are arranged are housed in the grip main body in a state of facing each other. The rollers are pushed by the bag when the bag 1 is inserted between the roller sets, and move along the inclined surface 10 to the inside (upward in fig. 3) of the insertion port 11. A locking surface is formed on the surface of the roller so as to frictionally hold the bag 1. As the locking surface, in the illustrated embodiment, a plurality of projections 15 and grooves 16 extending in the circumferential direction of the roller are formed, and the roller sets 13 and 14 are combined in such a positional relationship that the projections 15 enter the grooves 16 of the opposing roller. Therefore, even if the bag 1 inserted between the roller sets 13 and 14 from the insertion opening 11 is swung left and right, the plurality of rollers constituting the roller sets move while sandwiching the bag, and the burden of the sandwiching action is dispersed, so that the sandwiching action does not disappear. Therefore, even a structure which is heavy like a refill shampoo bag or the like and whose surface is easily slid can be reliably held. Further, a slide switch 19 is provided so as to be able to move up and down, so that the receiving piece 17 is respectively attached to the upper surfaces of the roller sets 13 and 14, and the roller sets 13 and 14 are biased in the inlet direction (downward in fig. 3) of the insertion port 11 by a spring 18 that presses the receiving piece 17, and either one of the roller sets is moved inward (upward in fig. 3). If the slide switch 19 is operated to move one of the roller sets, the gripping action is lost, and the empty bag can be easily taken out.

As shown in fig. 5, the storage box 7 is provided with a front panel 23 on the upper front surface and the lower front surface of a plate-like box base plate 21 having a hook hole 20 via a rising plate 22, and stores the bag 1 in a space between the box base plate 21 and the front panel 23, with the bag outlet 2 projecting downward from between the front panels. Further, an edge piece 24 bent in the back direction is formed around the box base plate 21, and a projecting piece 25 projecting in the back direction is formed at an appropriate position so as to be able to contact the wall surface, so that the box base plate 21 does not swing when the storage box 7 is hooked on the hook 5.

Fig. 6 and 7 show an embodiment of the pump 4, in which the pump includes a substantially cylindrical pump main body 26, and a housing space 29 having an inlet opening 27 and an outlet opening 28 is formed in the pump main body. As shown in fig. 7, the housing space 29 is circular in cross section, and the outer periphery of the pump main body 26 is formed in a substantially elliptical shape in cross section. An inlet cylinder 30 is formed around the inlet opening 27, a locking cap 31 is attached around the inlet cylinder 30, and the locking cap 31 is screwed into a screw portion formed in the outlet of the bag. The inlet cylinder 30 is provided with an inlet side valve 32 for opening and closing a flow path communicating with the inlet opening 27 so that contents such as shampoo can be taken out from the bag 1. The inlet side valve 32 is formed of a ball valve, and includes a valve seat 34 biased in the direction of the housing space 29 by a spring 33, and a ball 35 provided on the valve seat 34 so as to be positioned on the housing space side and to be separable from and contactable with each other. When the valve seat 34 abuts on and stops at the step portion 36, a flow path communicating with the inlet opening 27 with a gap between the ball 35 and the valve seat 34 is opened. If the housing space is pressurized and the ball 35 rises, the ball 35 comes into close contact with the valve seat 34, and the flow path leading to the inlet opening 27 is closed.

The outlet opening 28 is formed in a substantially middle portion of the pump main body 26, and an outlet side valve 37 for opening and closing the outlet opening 28 is formed in the outlet opening so as to discharge the content from the storage space, and a nozzle 38 facing downward is formed so as to communicate with the outlet side valve 37. The outlet side valve 37 is formed of a ball valve, and has a ball 40 biased by a spring 39 from the outside of the housing space 29 toward the outlet opening 28.

Main shafts 41, 42 that can move in the axial direction of the pump body so as to be able to approach and separate from each other are provided at both ends of the pump body so as to face each other, and pressurize the storage space 29 and take out the contents through the outlet-side valve 37. A spring 43 for biasing the main shafts 41 and 42 in a direction away from each other is provided between the main shafts. Two springs may be provided outside the pump body to individually bias the spindles (not shown). A cap 44 fitted to the outer periphery of the pump body 26 is attached to the end of each main shaft. One main shaft 41 is inserted into the sleeve 45, and supports the ball 35 of the inlet side valve 32 at its inner tip. An inclined surface 46 is provided on the front portion of the main shaft 41, and when the main shaft moves in the direction in which the main shaft approaches, the inclined surface 46 can press the ball 35 so that the ball 35 abuts on the valve seat 34 of the inlet opening to close the inlet opening 27. Further, sealing members such as O-rings are provided at appropriate positions of the valve seat 34 and the main shafts 41 and 42.

With the above configuration, according to the device shown in fig. 1 and 2, if the main shafts 41 and 42 are pushed inward by bringing hands into contact with the caps 44 at both ends, the ball 35 of the inlet-side valve 32 is directly pushed against the valve seat 34, and the flow path communicating with the inlet opening 27 is directly and reliably closed. Further, if the main shaft is moved, the content in the housing space 29 is taken out from the nozzle 38 through the outlet opening 28. When the pressing of the main shafts 41 and 42 is stopped, the inlet opening 27 is opened and the outlet opening 28 is closed by a suction action (vacuum action) when the main shafts move outward and return to their original positions, so that the contents can be taken into the storage space 29. Thus, the contents such as shampoo in the bag can be taken out to the end. Since the pressing force when the spindles 41 and 42 are operated acts only in the axial direction of the pump body 26 and does not act on the holding member 3 and the wall on which the holding member 3 is mounted, there is no possibility that the bag may fall off.

Fig. 8 shows an example of a bag 47 having a detachable outlet 48. An insertion fastener 49 is attached to the outlet 48 formed by cutting, and a pump 50 is connected to the insertion fastener 49. Referring to fig. 9 and 10, the fixing member 49 includes an insertion cylinder 51, a clip 53 rotatably attached to a support column 52 projected in an opposed state on the outer periphery of the insertion cylinder 51 via a pivot 53a, and a lever 54 attached to the clip 53 via a pivot 54a to operate the clip 53. The insertion tube 51 has a tip 55 formed obliquely so as to be easily inserted into the outlet 48, and a large diameter portion 57 at the rear end of the flow path 56 has a conical opening 58 for receiving a ball of a ball valve as described later. A screw 59 (fig. 11B and 11C) is formed on the outer surface of the large diameter portion, and a locking piece 61 (fig. 12A and 12B) having a saw-toothed locking protrusion 60 formed thereon is provided on the outer surface of the tip end side using a metal material. Referring to fig. 13A to 13C, the clip 53 is formed with a flap portion 62 and a recess 63 formed at substantially the center of the flap portion 62 so as to be fitted to the outer surface of the insertion tube 51, and an elastic member 64 made of rubber or the like is provided on the inner surface. A cam portion 65 that abuts on the peripheral surface of the insertion tube 51 when the lever 54 is tilted down along the insertion tube 51 is formed at the rear end, and a claw piece 67 that engages with a hook portion 66 of the clip 53 is formed at the front end (fig. 14A to 14C).

The insertion tube 51 is inserted into the outlet 48, which is opened by cutting a part of the bag 47, in a state where the lever 54 is pulled up (fig. 10), and the insertion tube 51 is sufficiently inserted into the bag main body. Then, if the lever 54 is laid down, the tip of the clip 53 is pressed against the outer surface of the insertion tube 51 by the cam 65 (fig. 9), and the flap 62 of the clip 53 is pressed against the bag and prevented from sliding by the locking piece 61 and the elastic member 64. Thus, the insertion fastener 49 seals the outlet 48 of the bag 47 and is securely attached to the bag, and the contents are unlikely to leak from the outlet.

Further, depending on the material of the bag, when the bag outlet is held by the clip, the sheet constituting the bag may not be bent along the outer surface of the insertion tube in a circular shape, and a slight gap may be formed between the inner surfaces of the engagement portions of the sheet, thereby causing leakage of the contents. In this case, as shown in fig. 15, a tubular contact member 81 formed of an elastic material may be provided on the outer periphery of the insertion tube 51 of the insertion fastener 49. As shown in fig. 16, the close contact member 81 has tabs 82 having a substantially triangular cross section on both sides thereof, and has fitting holes 84 for engaging with positioning projections 83 formed on the insertion tube 51. Thus, as shown in fig. 17, when the outside of the insertion tube 51 inserted into the outlet of the bag is held by the clip 53, most of the bag is held by the concave portion 63 of the clip, and the tab 82 protruding sideward enters between the pieces along the bag of the insertion tube. Further, since the outer surface of the tab is pressed by the wing portions 62 of the clip 53, the gap between the pieces of the bag is closed, and leakage of the contents is prevented.

Fig. 18 and 19 show an embodiment of the pump 50 connected to the insert fastener 49. The wall 68 of the pump main body is made of a soft material such as silicone rubber that can be contracted and restored, and a substantially spherical housing space 71 having an inlet opening 69 and an outlet opening 70 is formed in the pump main body. Further, if a transparent material is used as the soft material of the wall body, the inside of the housing space 71 can be seen through. The inlet opening 69 and the outlet opening 70 are formed by inner rings 72 and 73 formed of a metal material or a hard plastic material, and a nut 74 that is screwed into the screw 59 of the insert fastener 49 is provided on the outer periphery of the inner ring 72 of the inlet opening 69. An inlet-side valve 75 is provided in the inlet opening 69 so that the contents can be taken from the bag 47 into the storage space 71. In the embodiment shown in fig. 19, a ball valve is used, and a ball 76 is put inside the large diameter portion 57 of the insertion fixture 49, and when the ball 76 moves upward in fig. 19, the ball can closely contact the conical opening 58 of the insertion tube 51 to close the conical opening 58 and the flow path 56. When the ball 76 moves downward, the conical opening 58 and the flow path 56 are opened, and the content in the bag 47 enters the storage space 71 from the inlet opening 69.

The outlet opening 70 is provided with an outlet side valve 77 that opens and closes the outlet opening 70 to discharge the content that has entered the storage space 71 from the inlet opening 69. A nozzle 78 facing downward is formed at the middle portion of the valve main body so as to communicate with the outlet side valve 77. A ball valve is used as the outlet side valve 77, and the ball 79 is biased toward the outlet opening 70 by a spring 80.

With the above configuration, if the pump body 68 is compressed (gripped), the housing space 71 is pressurized, the ball 76 of the inlet-side valve 75 rises to block the flow path 56 of the insertion fastener 49, and the content entering the housing space 71 pushes the ball 79 of the outlet-side valve 77 open and flows out from the nozzle 78. When the compression (gripping) of the pump body 68 is stopped, the pump body 68 is expanded to the original state, the ball 79 of the outlet side valve 77 is pressed by the spring 80 to close the outlet opening 70, the ball 76 of the inlet side valve 75 is lowered to open the flow path 56, and the contents in the bag 47 are sucked into the storage space 71 through the inlet opening 70. Thus, the contents such as shampoo in the bag can be taken out to the end. The pressing force when the pump body is compressed (held) acts only on the pump body and does not act on the holding member and the wall on which the holding member is attached, so that the bag is unlikely to fall off. In the above embodiments, the ball valve is used as the valve, but other suitable valves may be used.

Fig. 20 and 21 show an embodiment of a pump 85 using a valve formed on a valve shaft as an outlet-side valve. In fig. 20, wall 87 of pump body 86 is made of a soft material such as silicone rubber that can be contracted and restored, as in the embodiment shown in fig. 18 and 19, and forms housing space 90 having inlet opening 88 and outlet opening 89. The support shaft 91 is inserted into the housing space. The support shaft 91 has an upper cylindrical portion 92 and a lower cylindrical portion 93, and a plurality of through holes 94 are formed in the upper and lower cylindrical portions. The upper cylindrical portion 92 accommodates a ball 96 of a ball valve constituting the inlet-side valve 95, and the ball 96 faces a valve seat 97 of the inlet opening 88. The plate 98 forming the valve seat 97 is fixed to the upper end of the upper cylindrical portion 92 by ultrasonic welding after a nut 99 is fitted to the pump body 86.

The lower cylindrical portion 93 protrudes below the pump body 86, and the nozzle 100 is fixed to the tip thereof by ultrasonic welding. A valve shaft 102 forming an outlet-side valve 101 is accommodated in the nozzle 100. The valve shaft 102 is inserted through the outlet opening to extend downward, and includes a valve 104 facing a valve seat 103 formed in the outlet opening 89, and the valve 104 is biased by a spring 105 in a direction in which it is pressed against the valve seat 103. As shown in fig. 20, an O-ring is provided on the valve 104. A small knob 106 is formed at the tip of the valve shaft 102 protruding from the nozzle 100 so that the valve shaft can move downward in fig. 20.

With the above configuration, the pump 85 shown in fig. 20 is connected to the bag by screwing the nut 99 to the screw formed in the outlet or the screw of the insertion fastener as described above. When the pump body 86 is gripped and contracted, the inlet-side valve 95 is closed by the pressurization, and the valve 104 of the outlet-side valve 101 moves downward against the spring 105, so that the content entered into the storage space 90 can be taken out from the nozzle 100. If the contraction of the pump main body is stopped, the pump main body is expanded to the original state. Then, by the vacuum suction action at this time, the inlet side valve 95 is opened, the contents enter the storage space 90 from the bag through the inlet side valve 95, the valve shaft 102 is pushed and raised by the spring 105, and the valve 104 is engaged with the valve seat 103 to close the outlet opening 89. If the contents solidify in the outlet opening portion due to long-term non-use, the outlet opening may be blocked by the solidified substance, and the valve may be unreliable in movement, thereby making it impossible to take out the contents. If such a situation occurs, the valve shaft 102 can be moved to remove the solidified material from the outlet opening by pulling the knob 106 formed outside the nozzle 100, and then the pump body can be contracted to take out the content as described above.
