Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to, for example, liquids filled and packaged in relatively large soft plastic packaging bags, such as dressings, soups, honey and juices, which may contain various seasonings, alcoholic beverages, granules or powders. In addition, when tea and other items are poured out several times and exhausted, it is easy to pour out and the outside air that may contain microorganisms, dust, etc. enters the plastic packaging bag and The present invention relates to a liquid packaged dispensing device and a dispensing structure for effectively preventing the contacted liquid material from returning to the plastic packaging bag.
[0002]
[Prior art]
When dispensing and using liquids such as detergents and shampoos packed and packaged in relatively large, soft plastic packaging bags, the dispensing operation is facilitated, and from a single dispensing, Various liquid take-out devices made of hard materials that can store plastic packaging bags have been proposed in order to facilitate the storage of plastic packaging bags in an upright position until the next dispensing operation. Yes.
[0003]
However, detergents, shampoos, etc. are not as affected as food and drink by oxidation due to the outside air and intrusion of dust etc. into plastic packaging bags, and various measures are taken for detergents, etc. since it is possible, many, the dispensing means comprising a tube and a pump member narrowing stabbed into the packaging bag, no strict ambient air barrier properties and the like are applied, the product rather to the packaging bag in Kyokuteki In general, it is common practice to discharge detergent or the like by compressing the outside air taken in the pump by a pump member.
[0004]
In contrast, the packaged articles are beverage, when a seasoning or the like, for each time of the dispense, the outside air incorporation into the packaging bag in the oxidation of the liquid material by the outside air itself, its taste, In addition to causing a decrease in flavor and the like, the liquid material may be soiled or corroded by microorganisms, dust, or the like that may be contained in the outside air.
[0005]
Therefore, JP-A-8-133307 discloses a valve chamber having an upper diameter-expanded portion and a lower-diameter portion for the purpose of preventing the outside air from entering the container every time the liquid is poured out. It has been proposed to attach a check valve configured by arranging a spherical valve body to a spout of a bag-like container.
This check valve allows the liquid material to be dispensed by rolling the valve body to the upper diameter-expanded portion of the valve chamber by tilting the container when the liquid material is dispensed. When the valve body rolls to the lower small diameter part of the valve chamber by returning the container to the standing posture, a part of the liquid remaining in the discharge port is sucked into the valve chamber, and the liquid level in the discharge port is kept inside. It is intended to retreat back.
[0006]
[Problems to be solved by the invention]
However, according to this proposed technology, the check valve is returned to a posture in which the upper diameter-expanded portion faces upward so that the liquid material is completely dispensed and the valve body in the valve chamber is moved back to the lower-diameter portion. When doing so, the situation where the outside air that may contain microorganisms and the liquid material that has been in contact with the outside air inevitably enters the container through the valve chamber, There was still a risk of oxidation by outside air and contamination by microorganisms.
[0007]
An object of the present invention is to solve such problems of the prior art, and the object of the present invention is to inject a liquid material filled and packaged in a relatively large flexible plastic packaging bag. Makes it easy for the packing bag to stand upright and store it between one and the next, as well as for the outside air to enter the packaging bag during the pouring operation. Provided is a liquid packaged dispensing device and a dispensing structure that reliably prevent the liquid in contact with the liquid from returning to the plastic packaging bag and sufficiently eliminate the risk of oxidation and contamination of the liquid in the bag. It is in.
[0008]
[Means for Solving the Problems]
According to the present invention, a liquid packaged dispensing device includes a rigid cylindrical body with a bottom wall that stores a soft plastic packaging bag filled and packaged with a liquid material directly or indirectly via a packaging box or the like. And a lid that fits into the upper end portion of the rigid cylindrical body, and the lid is provided with a lead-out nozzle that is inserted into the plastic packaging bag, and a check valve and a dispensing nozzle that are sequentially communicated with the lead-out nozzle A diaphragm that elastically deforms at a peripheral portion between a closed position that blocks communication between the lead-out nozzle and the dispensing nozzle and an open position that provides communication between the check nozzle and the check valve. constituted by a support member to restrain the displacement of the diaphragm in contact with the central portion of the diaphragm, the barbs inclusive tip of deriving the nozzle, with a tapered face shaped or inclined surfaces shaped tapered, its It is made of a tip a curved shape.
In this apparatus, a lead-out nozzle is inserted into a plastic packaging bag in a rigid cylinder, and a soft plastic packaging bag filled and packaged with a liquid material is fitted under the action of the rigid cylinder by fitting a lid to the rigid cylinder. It is possible to stably maintain the standing posture and wait for the liquid material in the bag to be poured out as required, so that it is possible to prevent unexpected liquid spillage due to the fall of the soft plastic packaging bag, etc. Can be prevented.
[0009]
Also, under this standing posture of the packaging bag, based on the normally closed function of the check valve provided on the lid, the diaphragm is brought into close contact with the housing under the action of atmospheric pressure there, and the discharge nozzle and the dispensing nozzle because it cuts off the communication between the outside care, etc. will not be entering into the packaging bag in.
On the other hand, the liquid material in the bag can be poured by grasping the rigid cylinder and tilting the cylinder, and thus the packaging bag, so that the dispensing is also easy and stable. Can be done automatically.
Here, when this liquid material is poured out, the liquid material that has flowed into the outlet nozzle exerts a hydraulic pressure on the diaphragm constituted by a plastic film, a rubber sheet, etc., and this is restrained by the displacement of the support member. Underneath, the bag is elastically deformed in the opening direction, so that the liquid in the bag can flow out smoothly from the outlet nozzle through the check valve and the dispensing nozzle without being affected by the diaphragm.
[0010]
On the other hand, when the required amount of liquid material has been poured out and the rigid cylinder and the packaging bag are turned and displaced in their upright directions, the elastic restoring force of the diaphragm to the original shape causes the liquid material in the outlet nozzle to move. When the fluid pressure exerted on the diaphragm exceeds the diaphragm, the diaphragm is closely attached to the housing at its peripheral edge based on the normally closed function of the check valve, and the communication between the outlet nozzle and the dispensing nozzle is completely blocked. To do.
[0011]
By the way, such pouring of the liquid material in the bag under the high flexibility of the packaging bag, the packaging bag itself contracts by an amount corresponding to the volume of the pouring liquid without taking in outside air into the bag. As a result, the soft packaging bag has a reduced-pressure atmosphere inside the bag based on its inherent elastic restoring force. Therefore, the diaphragm is adsorbed and held by the housing, so that the communication between both nozzles is more reliably cut off.
Thus, in this case, not only the liquid material is being poured out, but also when the dispensing is stopped, the intrusion of outside air into the packaging bag is sufficiently prevented based on the elastic return of the diaphragm to its original shape. As a result, the risk of oxidation, fouling, etc. of the liquid in the bag due to outside air can be effectively removed.
[0012]
In addition, even when the liquid material is left outside the diaphragm when the liquid material is stopped to be poured, the residual liquid material is further increased by the action of its weight on the diaphragm. Since adhesion is brought about, the return flow of the residual liquid material to the packaging bag is surely prevented.
[0013]
In the above-described dispensing device, an elastic film body is preferably attached airtightly to either the lid body or the rigid cylinder body, and the elastic film body itself, the rigid cylinder body or the lid body is elastically attached. When providing an air intake that allows the inflow of air to the inside of the film body and a communication path that allows the air inside the elastic film body to flow into the rigid cylindrical body, By pushing and deforming the elastic film body while the air intake is closed, the air taken in via the air intake can flow into the rigid cylinder through the communication path. Can press the plastic packaging bag. Therefore, in this case, the elastic film body is pushed and deformed while maintaining the pouring device and the packaging bag in an upright posture, thereby applying a compressive force to the liquid material in the bag, and pouring the liquid material through the diaphragm. It can flow out from the exit nozzle.
And, such stopping of the pouring is performed by releasing the plastic packaging bag and the liquid material in the bag from the action of the compressive force by stopping the pushing of the elastic film body, opening the air intake port, etc. Even when such pouring is stopped, the diaphragm elastically recovers as the hydraulic pressure acting on the diaphragm decreases, blocking the communication between the two nozzles, so that the outside air can enter the packaging bag. Can be sufficiently prevented.
[0014]
Here, it is preferable to provide a valve body that prevents the air once taken into the elastic film body from the air intake port from flowing out to the outside, for example, a plastic film or other thin film. According to this, when the elastic film body is pushed and deformed, the air inside the elastic film body can be smoothly and surely flowed into the rigid cylinder body without closing the air intake port with fingers. Therefore, the liquid material can be poured out more easily.
However here, the barbs inclusive tip of deriving the nozzle, a conical shape, with a tapered face shaped or inclined surfaces shaped tapered based pyramid shape or the like, by that its tip a curved shape, a plastic packing bag When inserting the lead-out nozzle into the unstretched film of itself or attached thereto, the unstretched film can be elastically stretched greatly with a curved tip surface, and the tapered end of the tapered surface or inclined surface Since the unstretched film can be elastically stretched more greatly by inserting the portion into the unstretched film, the packaging bag in which the lead-out nozzle is inserted is It is possible to secure a good airtightness between them by closely adhering to the surroundings.
[0015]
The liquid package dispensing structure according to the present invention has the plastic packaging bag itself around the tip of the outlet nozzle inserted into the plastic packaging bag of any of the above-described dispensing devices. Or an unstretched film attached thereto is elastically adhered. According to this configuration, as described above, the airtightness between the lead-out nozzle and the non-stretched film can be improved, and entry of outside air into the packaging bag from between them can be sufficiently prevented.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a longitudinal sectional view showing an embodiment of a pouring device according to the present invention, in which 1 is fitted to a rigid cylinder with a bottom wall, and 2 is fitted to the upper end portion of the rigid cylinder 1. This also shows a lid mainly composed of a rigid material.
[0017]
Here, the rigid cylindrical body 1 has a space for storing the soft plastic packaging bag 3 filled and packaged with a liquid material directly or indirectly with the flexible plastic packaging bag 3 in the box 4 as shown in the figure.
[0018]
On the other hand, the lid 2 is provided with a tapered lead-out nozzle 5 that protrudes from the central portion thereof toward the rigid cylinder and is inserted into the top wall of the plastic packaging bag 3. Each of the stop valve 6 and the discharge nozzle 7 is provided, and the check valve 6 is a diaphragm that is in close contact with the check valve housing 8 at the peripheral edge in the figure, for example, a silicone rubber or elastomer having a thickness of about 0.3 to 2.0 mm. consisting etc., or a diaphragm 9 made of plastic film of 7~20μm thickness of the diaphragm 9, in contact with the upper side in the figure, blocking it, the separation displacement from the housing 8, which is also highly And a rigid support member 10.
Under the action of atmospheric pressure on the diaphragm 9, the check valve 6 allows the outlet nozzle 5 and the dispensing nozzle 8 to communicate with each other while the peripheral portion of the diaphragm 9 is in close contact with the housing 8 as illustrated. On the other hand, when the fluid pressure of the liquid material in the bag acting on the lower surface side of the diaphragm 9 is larger than the elastic force of the diaphragm 9, the peripheral edge portion of the diaphragm 9 is elastic in the direction away from the housing 8. The deformation functions to provide communication between the nozzles 5 and 7. In this case, the displacement of the diaphragm as a whole from the housing 8 is prevented by the support member 10 in contact with the central portion.
[0019]
In the pouring device configured as described above, in addition to each of the rigid cylinder 1 and the lid 2, when both of the fitting portions also have high airtightness, the cylinder 1 and the lid 2. In at least one of the figures, the air communication hole 11 is provided in the lid body 2 to facilitate smooth and easy crushing deformation of the packaging bag 3 due to the extraction of the liquid material in the soft plastic packaging bag 3. It is preferable for ensuring the smoothness of the liquid material.
[0020]
As shown in the drawing, when the packaging bag 3 is stored in the rigid cylindrical body 1 together with the box 4, the smoothness of the pouring is made by making one or a plurality of window holes 12 in the box 4. Thus, it is sufficiently secured by making the outside air reach the packaging bag 3 more smoothly. By the way, such a window hole 12 can also be used for visually checking the remaining amount of the liquid material in the bag when the rigid cylinder 1 is made of a transparent material.
[0021]
Further, the insertion tip portion 13 of the lead-out nozzle 5 of such a device has a tapered surface shape as shown in the figure or a tapered surface shape such as a straw based on a conical shape, a pyramid shape, etc. by the surface with curved shape, the barbs included tip portion 13, for example, hitting the plugging in the packaging bag 3 made of a non-oriented film of more or multiple layers, the non-stretched film, the curved distal end face Since the distal end portion 13 is penetrated in a state of being largely elastically stretched, and the continuous insertion of the distal end portion 13 causes the through hole to be further elastically expanded by the tapered or inclined tapered portion, FIG. When the lead-out nozzle 5 is in the stabbed state as shown in FIG. 5, the packaging bag unstretched film 14 is in close contact with the peripheral surface of the nozzle based on its own elastic restoring force. Sufficient air-tightness and result in a liquid-tight seal.
[0022]
On the other hand, as shown in FIG. 3, for example, the plastic packaging bag 3 includes an outermost stretched base film layer 15, an unstretched film layer 16 as an intermediate layer, and an unstretched film layer 17 as a sealant layer. When making a laminated structure, when all those layers 15, 16 and 17 are firmly joined and laminated, from the stretched base film layer 15 side, the lead-out nozzle 5 is inserted as shown in FIG. A crack occurs in the base film layer 15, and the crack propagates to the other non-stretched film layers 16 and 17 and travels over a wide range. Therefore, between the packaging bag 3 and the outlet nozzle 5. Thus, it becomes impossible to ensure the airtightness as described above.
Therefore, as shown in FIG. 3A, the unstretched film layer 17 that is the innermost layer of the laminated film is laminated through the release layer 18 in the vicinity of the required insertion position of the lead-out nozzle 5 and led out. When the nozzle 5 is pierced, the innermost unstretched film layer 17 is configured to be easily peeled from the intermediate layer as indicated by a virtual line in the figure under the action of the peeling layer 18, As shown in FIG. 3 (b), an unstretched film 19 having a required ring shape is joined to the inner surface of the sealant layer in an airtight and liquid-tight manner at the peripheral portion.
[0023]
In any of these cases, the lead-out nozzle 5 inserted from the outermost layer side is passed through the peeled portion of the non-stretched film layer 17 or the non-stretched film 19 under an extension deformation in its elastic region, thereby It is possible to provide the same airtightness as described above. In this case, even if the unstretched film layer 16 firmly bonded to the stretched base film layer 15 has crack propagation, progress, etc., it is not until the peeled portion of the unstretched film layer 17 and the unstretched film 19. The cracks do not propagate and the cracks do not propagate outside their peeled portions and attachment areas.
[0024]
By the way, such insertion of the outlet nozzle 5 into the plastic packaging bag 3 put in the other box 4 made of paper, as illustrated in FIG. 4, is performed at the central portion of the upper lid 20 of the box 4. By providing in advance slits 21 or small holes that allow the entry of the above, it can be performed smoothly and easily.
[0025]
The dispensing of the liquid material in the bag under the application state as shown in FIG. 1 of the above-described dispensing device, as shown in FIG. In this case, the liquid material in the bag that has flowed into the outlet nozzle 5 presses the diaphragm 9 and elastically deforms the peripheral portion thereof in a direction away from the housing 8. Since the outlet nozzle 5 and the outlet nozzle 7 communicate with each other, the liquid in the bag is smoothly discharged from the outlet nozzle 7.
[0026]
In this case, since the escape displacement of the entire diaphragm from the housing 8 is reliably prevented by the support member 10, each of the opening deformation of the diaphragm and its elastic return to the original shape described later is It will always be done reliably at the expected position.
[0027]
On the other hand, after finishing dispensing the required amount of liquid material, the pouring device is tilted in the reverse direction toward the original standing posture. In this case, when the pressing force exerted on the diaphragm 9 by the liquid material in the bag becomes smaller than the self-returning elastic force of the diaphragm 9, the diaphragm 9 is always in contact with the housing 8 as shown in FIG. 1. It returns to the closed posture elastically, shuts off the communication between the nozzles 5 and 7, and stops the liquid material from being poured out.
Here, this elastic return of the diaphragm 9 is caused by the elastic restoring force inherent to the diaphragm, or the sum of the elastic restoring force and the weight of the liquid material before flowing down from the dispensing nozzle 7, Since it is carried out immediately when the pressure is overcome, the intrusion of outside air into the packaging bag 3 due to the stoppage of the liquid material is sufficiently prevented, and it once flows out to the outside of the diaphragm 9. The liquid material that has come into contact with the outside air is reliably prevented from flowing back into the packaging bag by the diaphragm 9 in the closed posture.
[0028]
By the way, this liquid material that is prevented from flowing back into the bag and stays on the diaphragm 9 increases the adhesion of the diaphragm 9 to the housing 8, and at the same time, the liquid material is poured out. The inherent elastic restoring force in the direction of expanding the volume of the plastic packaging bag 3 that is allowed by reducing the volume without taking in the outside air, after the stoppage of the pouring, also generates a force that increases the adhesion force. Therefore, the communication cutoff function of the diaphragm 9 after finishing the dispensing is further enhanced.
[0029]
Thus, in this case, when the liquid in the bag is not poured out, by keeping the pouring device in an upright position, it is possible to surely prevent the liquid material in the bag from being accidentally leaked out. Based on the elastic restoring force of the diaphragm 9, it is possible to sufficiently prevent the outside air and the liquid material once in contact with the outside air from entering the packaging bag due to the stoppage of the dispensing.
[0030]
6 is a longitudinal sectional view showing another embodiment of the apparatus according to the present invention, which is a sectional view taken along the line VI-VI in FIG. 7 showing a transverse section taken along the line VII-VII in FIG. is there.
In particular, the top wall of the lid 2 is formed of an elastic film body 22 which is airtightly attached, and can be made of, for example, rubber, and the inside of the elastic film body 22 swelled upward in a dome shape is formed in the air chamber 23. In addition, the air chamber 23 is communicated with an air intake port 24 provided on the side wall of the lid. This communication can be performed by directly opening the air intake 24 into the air chamber 23. Here, however, the air intake 24 is shown in FIG. 8 showing a cross section taken along line VIII-VIII in FIG. The air chamber 23 is opened through a communication path 25 to the rigid cylinder 1 that appears in FIG. In addition, it is also possible to provide a plurality of the communication paths 25, which are shown as one in the drawing.
Further, in this embodiment, as shown in FIG. 6, a valve body 26 that allows inflow of air from the air intake port 24 but prevents outflow of air from the air intake port 24, such as an elastic piece, is provided in the intake port 24. At the opening to the rigid cylinder side.
[0031]
The pouring device configured as described above is used by inserting the outlet nozzle 5 into the plastic packaging bag 3 stored directly or indirectly in the rigid cylinder 1 in the same manner as described above. However, in this case, the liquid material in the bag can be poured by pressing the elastic membrane body 22 as indicated by the phantom line in the figure and applying the air in the air chamber 23 under the action of the valve body 26. The compressed air can be supplied by flowing the compressed air into the rigid cylinder 1 through the communication passage 25 and crushing and deforming the packaging bag 3 with the compressed air. The tilting operation 3 is not necessary.
[0032]
By the way, such a crushing deformation of the packaging bag 3 causes the elastic film body 22 to be pressed and deformed in a state where the intake port 24 is closed from the outside when the valve body 26 is not provided in the air intake port 24. In any of these cases, the crushed and deformed liquid material in the packaging bag 3 is applied to the diaphragm 9 under the pressure from the housing 8 as described above. Based on the elastic deformation in the separating direction, the liquid material is poured out.
On the other hand, the stopping of the pouring can be performed by at least one of releasing the elastic film body 22 from the pressing force and releasing the blockage of the air intake port 24. For example, the valve body 26 is provided. In the apparatus, when the elastic film body 22 is released from the pressing force, the elastic film body 22 takes the original bulging posture shown by the solid line in the drawing while taking outside air from the air intake port 24 with the valve body 26 opened. Since the elastic bag returns to its original state and the packaging bag 3 is placed in a reduced-pressure atmosphere during that time, the liquid pressure exerted on the diaphragm 9 by the liquid in the bag rapidly decreases simultaneously with the release of the pressing force on the elastic film body 22. As a result, the diaphragm 9 quickly returns to its original shape in contact with the housing 8 and immediately shuts off the communication between the nozzles 5 and 7. Therefore, also when stopping the pouring of the liquid substance in the bag here, the diaphragm 9 comes into contact with the housing 8 before the outside air and the residual liquid substance enter the packaging bag 3.
[0033]
FIG. 9 is a longitudinal sectional view showing still another embodiment, which is provided with an air inlet 24 in the rigid cylindrical body 1 and a valve body 26 inside the air inlet 24. .
Similarly to the above, this apparatus can also pour out and stop the liquid material in the bag without the tilting operation of the apparatus under the action of the elastic film body 22.
[0034]
Although the embodiment of the present invention has been described with reference to the drawings, the valve body 26 can be omitted from the positions shown in FIGS. 6 and 9, and in this case, the air intake 24 can be provided as required. By closing with a finger, the elastic film body 22 can exhibit a required function.
Moreover, in the place shown in those figures, the elastic film body itself can be provided with an air intake with or without a valve body.
6 and 9, an elastic film body can be airtightly attached to the rigid cylinder 1, for example, the side wall thereof. In this case, the air chamber inside the elastic film body is connected to the cylinder. With the valve body functioning in the same manner as described above, the rigid cylindrical body 1, the lid body 2 or the elastic film body itself is opened to the inside of the cylindrical body through the communication path provided in the body side wall. By providing the air intake without a valve body, the extraction device can function in the same manner as those shown in the drawings.
[0035]
【The invention's effect】
Thus, according to the present invention, the liquid material is poured out from the soft plastic packaging bag filled and packaged with the liquid material, and the packaging bag is stored in an upright position when the liquid material in the bag is not poured out. In addition, the liquid in the bag is poured out, especially when the outside of the bag is stopped, and the liquid that has been in contact with the outside air is returned to the bag. Flow can be reliably prevented under the action of a check valve.
