Description

  The present invention relates to a spout stopper to be attached to a liquid container such as a standing pouch type in which sheets are superposed, such as a deformable free liquid container.

  Conventionally, there are liquid containers formed of a flexible packaging material such as a standing pouch type, and in toiletry products such as body soaps and rinses, refills are housed and sold in such liquid containers. In recent years, many products filled in a flexible liquid container having a relatively large capacity (for example, 1 to 2 liters) for refilling have been distributed.

  Further, many liquid containers such as a standing pouch type have a synthetic resin spout stopper formed separately at the upper corner of the container in order to easily pour out the liquid. This type of spout stopper is attached to the packaging material of the container body by heat welding or ultrasonic welding. For example, a spout tube, a screw-on cap that covers the top opening of the spout tube, and a spout Some have a boat shape that is integrated with the lower portion of the cylinder and is easily sandwiched between container packaging materials, and includes an attachment portion that is thermally welded or ultrasonically welded to the upper portion of the container.

  By the way, in a liquid container with a large inner volume, it is ensured that the container leaks from the spout stopper at the distribution stage where the product filled with the container is shipped from the factory and sold in stores such as home centers. Need to be prevented. Furthermore, even if the purchaser is unfamiliar with the handling of unused product containers and carelessly removes the cap, it is necessary to prevent the contents from flowing out from the spout stopper as a safety measure. From this point, in a liquid container consisting of a flexible sheet such as a standing pouch with a large internal volume, the inside of the dispensing cylinder is closed with a closing plate, and the opening can be removed by pulling a pull ring on a part of the closing plate A spout stopper having a structure provided with a portion is effective.

  Moreover, the capacity of the above-mentioned liquid containers filled with refills such as toiletry products has become larger than that of the dedicated container to be refilled, so that the user can move from a liquid container to a dedicated container. It will be divided into times. And, when the contents are poured out from the liquid container, the container itself is deformed so as to be crushed by receiving atmospheric pressure, although the pulsation does not occur when the blow container is poured out, and the shape inside the deformed container is followed. The state in which the contents flow into the spout stopper with the turbulent flow and the direction of the flow from the upper opening of the spout tube is not stable occurs every time the refill is performed.

  In addition, the cap is attached and removed each time refilling is performed, and when the contents remain, the upper opening of the dispensing cylinder is closed with the cap and the liquid container is stored. Therefore, there is a problem that the cap is easily lost. In order to prevent this loss, it is effective to connect the cap to the upper portion of the dispensing cylinder so that the cap can be rotated like a general spout stopper structure integrally provided with a self hinge.

  However, when the contents on the side of the liquid container are reduced by refilling work, the entire container is turned upside down so that the liquid does not remain inside the deformed liquid container, and the upper part of the dispensing tube is placed at the mouth of the dedicated container. If the cap is connected to the upper portion of the dispensing tube as described above, the cap becomes an obstacle and the dispensing tube cannot be inserted into the mouth of the dedicated container. Therefore, it cannot be set as the structure which connected the cap to the upper opening side of the extraction | pouring cylinder, and the problem that the loss of the cap mentioned above easily arises cannot be solved.

  Numerous ideas have been proposed for the spout stopper, and it can be studied as a countermeasure against the above-mentioned problems. For example, in Patent Document 1, there is shown a point in which a thin flat fin is integrally provided on the inner cylinder portion of the spout stopper, and the use of the fin is effective in rectifying the contents flowing through the pour pipe. Can be considered.

  Further, in Patent Document 2, it is shown that the cap connected to the spout tube of the spout stopper can be folded back deeply to the outer surface side of the spout tube and temporarily fixed. The use of the technique disclosed in Patent Document 2 can be considered as a countermeasure against loss of the image.

Japanese Utility Model Publication No. 03-072655 JP 2014-108809 A

  However, in the device shown in Patent Document 1, since each fin serving as the rectifying means has a movable shape, there arises a problem that it is not possible to suppress the turbulence in the flow of the contained items to be poured out.

  Moreover, in the device shown in Patent Document 2, when the cap is temporarily fixed, the cap is attached to the outer peripheral surface of the spout tube of the spout stopper, and the spout stopper is attached to the dedicated container. Cannot be inserted into the mouth. Therefore, the spout is poured in a state where the spout stopper is close to the mouth portion of the dedicated container. However, the spout plug attached to the flexible liquid container as described above is a type in which the cap is attached / detached. With a spout stopper that has a small diameter for insertion into the mouth of a dedicated container, there is a large change in how the passage from the container body (liquid container) to the spigot is stuck. The flow from the upper opening of the cylinder tends to be disturbed, and there arises a problem that the contents cannot be easily and safely transferred.

  In view of the above circumstances, an object of the present invention is to provide a spout stopper attached to a liquid container molded from a flexible packaging material, and to prevent the flow of the contents from being disturbed when the contents are refilled. It is an object of the present invention to provide a spout cap with a cap that can be refilled by being brought close to or inserted into the mouth of the bottle.

  Next, the present invention will be described in detail based on the embodiment shown in FIGS. In the figure, reference numeral 1 denotes a spout stopper for a liquid container, which is attached to a flexible and freely deformable liquid container, for example, a liquid container (liquid container) such as a standing pouch in which sheets are stacked and the opposite sides of the sheet are heat sealed. It is a synthetic resin plug and is attached to the liquid container by heat welding or ultrasonic welding.

  As shown in FIG. 3, the spout plug 1 includes a pour tube 2, a plate-like closing plate 3 disposed inside the pour tube 2, a pull ring 4 attached to the closing plate 3, A cap 6 that covers the upper opening 5 of the dispensing cylinder 2 so as to be openable and closable, and a mounting portion 8 that is located at the lower part of the dispensing cylinder 2 and that opens the inlet 7 continuous with the inside of the dispensing cylinder 2. It is provided as a unit. The spout plug 1 is a port plug that is attached so as to be sandwiched between the sheet sides at the upper corner of the standing pouch, and the attachment portion 8 has the welded portion 8a so as to be sandwiched between the sheet sides of the two surfaces. It is formed in a boat-like shape, and the bulkiness of the welded portion 8a has a height corresponding to the packaging material seal side of the standing pouch, and the peripheral surface of the welded portion 8a is finished to a surface shape corresponding to ultrasonic welding. ing. (See Figures 1 and 2)

  The closing plate 3 disposed in the inside of the dispensing tube 2 is disposed inside the dispensing tube 2 until the opening operation is performed on the liquid container in which the pouring plug 1 is attached and the contents are filled. Close. The closing plate 3 has a planned opening portion 9 surrounded by a thin portion that can be broken, and the pull ring 4 is integrally formed in the planned opening portion 9, and the pulling ring 4 is pulled when necessary so that the thin portion Ruptures, the planned opening 9 is removed, and an opening through which the contents can be poured is formed. In addition, about the point which pulls a pull ring and forms an opening, it is the same as the spout stopper which has a normal pull ring.

(Opening with closing plate)
In the spout stopper 1 of the present embodiment, when the contents are poured out after the liquid container to which the spout stopper 1 is attached is opened as described above, the flow of the contents is a coherent flow. In order to make it easier to do the dispensing work. First of all, the shape of the planned opening 9 is devised.

  The plan opening 9 has a non-circular planar shape, and has a substantially oval shape with the radial direction of the dispensing tube 2 as the longitudinal direction. And the direction along the direction which falls the container at the time of pouring out from the liquid container which attached the spout stopper 1 is made into the direction used as the longitudinal direction of the opening scheduled part 9. FIG. 4A shows the closing plate 3 as viewed from above without the pull ring, FIG. 4B shows the cross-sectional state along the short direction of the planned opening portion 9, and FIG. 4C shows the closing plate. 3 is shown as viewed from below. As shown in the figure, the opening scheduled portion 9 has a small circular shape on the upper side when the liquid container is tilted and a small circular shape on the lower side and a circular portion on the lower side. Are formed in an overlapping shape.

  By pulling the pull ring 4 and removing the planned opening 9, an opening having a shape in which a small circular portion and a large circular shape are overlapped is obtained. The shape of the opening formed by removing the planned opening 9 is preferably a shape in which the direction along the direction when the liquid container is tilted is long, but the shape of the opening edge, that is, the opening The outer peripheral shape of the forming portion 9 is not limited to the shape described in this embodiment.

(rectifier)
Further, the spout stopper 1 in the present embodiment is also provided with the following device for facilitating the pouring operation. In the figure, reference numeral 10 denotes a rectifying plate. The rectifying plate 10 rectifies the rectification while suppressing the disturbance of the flow of the incoming material entering the inflow port 7 when the liquid container is tilted to pour out the stored material. It is a board that has the role of making it flow out stably with a coherent flow.

  The rectifying plate 10 is provided along the height direction of the extraction cylinder 2 from the opening outer peripheral plate portion 11 around the planned opening portion 9 to the lower end of the inner peripheral surface of the extraction cylinder 2. A plurality of them are arranged at intervals in the inner peripheral surface direction. Each of the rectifying plates 10 is continuously integrated with the back surface of the opening outer peripheral plate portion 11 and poured out to a position close to the thin portion between the planned opening portion 9 and the opening outer peripheral plate portion 11. Projecting from the inner peripheral surface of the tube 2 toward the inner center of the dispensing tube 2. Further, the rectifying plate 10 is integrated with the inner peripheral surface of the dispensing cylinder 2 up to the lower end, and as shown in FIGS. 3 (b) and 4 (b), the side of each dispensing cylinder center side is It is set as the state which inclined toward the inner peripheral surface lower end of the extraction pipe | tube 2 from the said thin part position.

  As described above, since the plurality of rectifying plates 10 are formed integrally with the pouring tube 2 across the inner peripheral surface of the pouring tube 2 and the opening outer peripheral plate portion 11, each of the rectifying plates 10 is deformed. It is a highly rigid plate. Therefore, when pouring the contents by tilting the liquid container, the liquid container is deformed so as to be crushed under the pressure from the atmospheric pressure, and the contents are distorted under the influence of the deformation. Even if it flows into the inlet 7 of the spout 1, the rectifying plate 10 is not deformed so as to be bent in accordance with the turbulent flow.

  Since the rectifying plate 10 has high rigidity and does not cause deformation such as bending, the container that has reached the position of the rectifying plate 10 from the inlet 7 in a turbulent flow state is opened (opened) while remaining in the turbulent flow state. In this case, the disturbance of the flow is suppressed without passing through the opening formed in the above manner, and the flow is made into a coherent flow through the opening. Therefore, it is possible to prevent the contents from being poured out from the upper opening 5 of the pouring cylinder 2 as a flow whose direction is fixed, and the pouring direction cannot be determined due to the influence of the deformation of the container.

(cap)
FIG. 5 shows a state in which the upper opening 5 of the dispensing cylinder 2 is closed with the cap 6, and the cap 6 is not directly connected to the dispensing cylinder 2 as shown in FIG. 5. It is connected to the upper end of the support 12 at a position separated from the dispensing cylinder 2 through a flexible thin plate-like connection band 13 so as to be freely rotatable and supported by the support 12. A cap 6 is provided so as to cover the upper opening 5 of the dispensing tube 2.

  As shown in FIG. 3 (b), the support 12 is directed from the height position lower than the height position of the closing plate 3 toward the outer side in the radial direction of the pouring cylinder 2 on the outer peripheral surface of the pouring cylinder 2. The extended horizontal plate 14 and the vertical plate 15 rising from the horizontal plate 14 toward the upper side in the pouring cylinder height direction are formed in a shape bent in a substantially L shape. It extends and reaches the upper surface of the mounting portion 8 so as to be integrated with the mounting portion 8. Further, the horizontal plate 14 is also configured as a part of a locking rib 16 projecting outward around the outer periphery of the dispensing tube 2 for use in locking and conveying the spout stopper 1. .

  The support 12 is one side in the longitudinal direction of the planned opening portion 9 and is located on the upper side when the liquid container attached with the spout stopper 1 is tilted for pouring, and the cap 6 is opened. Sometimes the cap 6 is separated from the dispensing cylinder 2, and the cap 6 can be rotated to the upper side when the container is tilted by the dispensing.

  In this Embodiment, it is provided so that the cap 6 can be detachably temporarily fixed to the position which does not interfere with the flow of the accommodation to pour out. As shown in FIG. 2, the holding means 17 is integrally disposed on the surface of the support 12 opposite to the dispensing cylinder 2 of the vertical plate 15, and the holding means 17 opens the upper opening 5. The cap 6 is provided so as to be held at a position separated from the dispensing cylinder 2.

  The holding means 17 has a jetty 18 projecting outward from the vertical plate 15, the tip edge is thick, and a convex thick wall portion 19 is arranged upward to make the vertical cross-sectional shape a bowl shape. is there. As shown in FIGS. 6 and 9, the holding means 17 is detachably locked to the holding means 17, which is integrally provided on the upper surface side of the opened cap 6, so that the holding means 17 is attached to the cap. The cap 6 is held so as not to move, and the opened cap 6 is designed not to interfere with the flow of the contents to be poured out.

(Insertion space)
FIG. 7 shows a state in which the liquid container 21 is tilted and the contents to be poured out. When the quantity to be poured out decreases, the spout stopper 1 itself is placed inside the mouth of the counterpart container. It is considered that the refilling operation from the liquid container is simplified if the liquid is dispensed. 8 and 9 show an example of dispensing according to the present embodiment having the device of this point, and shows a state in which the spout stopper 1 is placed in the mouth 23 of the counterpart container 22 (dedicated container). ing.

  In the spout stopper 1 of the embodiment, the device has been devised so that the liquid container 21 is turned upside down and the pouring cylinder 2 which is upside down is stably positioned inside the mouth 23 of the counterpart container 22, As shown in FIGS. 3B and 9, the insertion space portion 24 into which the peripheral wall of the mouth portion 23 of the counterpart container 22 can be inserted while the dispensing cylinder 2 and the vertical plate 15 of the support 12 are separated from each other. Is provided. Since the insertion space portion 24 is formed in the outer peripheral portion of the dispensing cylinder 2 in this way, the liquid container 21 is turned upside down while the contents are being poured out. By inserting a part of the mouth part 23 and bringing the mouth part 23 into contact with the lateral plate 14 of the support 12, the weight on the liquid container side can be supported by the counterpart container 22. It becomes easy to speak.

  In the above-described example, the length of the connecting band 13 that connects the cap 6 and the support 12 is short and forms a self-hinge, but the cap 6 is deeply covered with the dispensing cylinder 2. In this case, the length of the connecting band 13 may be increased. FIG. 10 shows an example of this, and shows a portion of the connecting band 13 that connects the cap 6 to the support 12. In FIG. 10, the holding means 17 and the receiving portion 20 are not shown for easy explanation of the long connecting band 13.

  As in the above embodiment, the connecting band 13 itself has one band end 25 connected to the support 12 and the other band end 25 connected to the cap 6. 13 is a main plate portion 26 is located. And the strip | belt-plate part 26 is made into flat form in the state (when a cap is open) with the connection belt | band | zone 13 open, The planar shape is made into the substantially rectangle which makes the direction orthogonal to a support body cap connection direction long. Each of the band end portions 25 has a substantially triangular cross section in a direction along the band plate portion 26.

  In many cases, a twist (the direction of the twist is indicated by an arrow in FIG. 10) is added to the connecting band 13 having a certain length when the cap 6 is opened and closed. 11 is substantially rectangular, as shown in FIG. 11A, the opening angle θ between the folding position X and the folding position Y at the time of twisting on the outer side of the band plate is narrow, and the degree of twisting is small. . Therefore, if a twist is often applied during the opening / closing operation of the cap 6, the stress tends to concentrate locally on the connection band 13, and the cut easily occurs. For this reason, the selection of the molding material for the spout tool and the design of the thickness of the connection band 13 must be taken into consideration so that the connection band 13 is not cut. The degree of freedom may be reduced.

  In view of this, with respect to the connection band 13, FIGS. 11B and 11C show modifications in which the range of adaptation to twisting is widened. In the modification shown in FIG. 11 (b), the band end portions 25 are arranged opposite to each other at the center position of the band plate portion 26 so that the planar shape is substantially a half-moon shape and is orthogonal to the support cap connecting direction of the band end portion 25. A part of the strip plate portion 25 is extended to a side portion in the direction (longitudinal direction of the strip plate portion 25). Further, in the modification shown in FIG. 11C, the planar shape is a trapezoidal shape with the band end portions 25 facing each other at the center position of the band plate portion 26. Similarly, a part of the band plate portion 25 is extended to a side portion of the band end portion 25 in a direction orthogonal to the support cap connecting direction.

  As shown in FIG. 11, the center width 26a of the band plate portion 26 in FIG. 11A is the same as the center width 26a in the modification shown in FIGS. 11B and 11C. In addition, compared with the end width 26b (26b = 26a) of the band plate portion 26 in FIG. 11 (a), the end width 26b ′ is increased in the modified examples of FIGS. 11 (b) and 11 (c). (26b <26b ′). Therefore, the opening angle θ ′ of the modification of FIG. 11B and the opening angle θ ″ of the modification of FIG. 11C are larger than the opening angle θ of the example of FIG. 11 (b) and 11 (c), the coupling band 13 has an effect that the range of adaptation to twisting is widened and is difficult to cut.

  11B is compared with a modification in which the band end portion 25 in FIG. 11C is trapezoidal, the opening angle θ ′ When the opening angle θ ″ is the same, there is a straight flat head portion 25a at the band end portion 25 in FIG. 11C, so that it is difficult to twist in the modification of FIG. 11C.
