Description

  The present invention relates to a spout structure provided at a mouth portion of a liquid container that contains a liquid, and a pouring tool attached to the mouth portion of a liquid container.

  As this type of conventional spout structure or pour tool, for example, the one described in Patent Document 1 is known.

  In the pouring tool described in Patent Document 1, a gland that is engaged with the neck portion or the discharge port of the liquid container, a sleeve portion integrated with the gland, and watertight engagement within the sleeve portion can be rotated. And an insertion portion provided with a handle. The ground axis is perpendicular to the rotational axis of the plug. A liquid opening that connects the gland and the sleeve portion is provided, and a monolithic tubular protrusion is provided in the gland and communicates with the sleeve portion by an air port.

  An internal partition is provided in the insertion portion, and the internal partition separates the inside of the insertion portion into a liquid discharge passage (also referred to as a liquid flow passage) and an air reflux passage (also referred to as an air flow passage). The wall of the insertion part is provided with a liquid inlet communicating with the liquid discharge passage and an air outlet communicating with the air reflux passage. By rotating the insertion part in the sleeve so that the liquid inlet coincides with the liquid opening and at the same time the air outlet coincides with the air outlet, the liquid can be poured out through the liquid flow path. If the inlet is rotated within the sleeve so that the liquid inlet does not coincide with the liquid opening and the air outlet does not coincide with the air opening, the liquid is prevented from being dispensed.

  By the way, in such a pouring tool, since the air flow path is formed in parallel with the liquid flow path, when the liquid is ready to be poured, not only the liquid flow path is first used. The liquid flows out in a state where the entire air flow path is filled with the liquid. In order to establish an air flow path in the air flow path that is completely filled with liquid, it is necessary to reliably form a pressure difference between the internal pressure and the external pressure of the liquid container. If the pressure difference between the internal pressure and the external pressure cannot be reliably formed due to deformation or the like, a situation in which the liquid flow is likely to stop is likely to occur. In particular, when the liquid container is made of a material having easy deformability, such a fluid flow is likely to stop.

  Therefore, the applicant of the present application has proposed in Japanese Patent Application No. 2008-9833 to form an orifice in the air flow path as a spout structure or a pour tool for solving such a problem.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 are views showing a liquid container spout structure according to the present invention and a spouting tool constituting the spout structure. In this example, the pouring tool 10 is detachably attached to the mouth portion 12a of the liquid container 12, and is a single plastic part separate from the liquid container 12. For example, when the liquid container 12 is sold in a store, the liquid container 12 is separated from the liquid container 12, and the dispensing tool 10 is attached to the liquid container 12 when the liquid is dispensed from the liquid container for dispensing or other purposes. Can be used. However, the spout structure according to the present invention is not limited to being composed of parts separated from the liquid container 12, but can also be composed of a part integrally attached to the mouth of the liquid container 12 so as not to be detachable. It is.

  The liquid container 12 may be a bottle made of a plastic material, a flexible bag in a BIB (bag in box), or any other container. In the case of a bottle made of a plastic material, the bottle may be made of a relatively soft material having high deformability, or may be made of a relatively hard material having low deformability.

  Moreover, the liquid accommodated in the liquid container 12 can be made into the thing of low viscosity-medium viscosity (0.9-420 mPa * S).

  The dispensing tool 10 has an annular attachment body 20 attached to the mouth portion 12a of the liquid container 12, a main body 22 extending from the attachment body 20, and a shaft body 24 inserted into the main body 22 and made rotatable. ing. The mounting body 20, the main body 22, and the shaft body 24 can be molded articles formed by injection molding or the like, and any synthetic resin material such as polyolefin resin or polystyrene resin can be used as the material thereof. Can do.

  Each member will be described in detail with reference to FIGS.

  The mounting body 20 has a threaded portion 20a (FIG. 4) formed on the inner peripheral surface thereof so as to be screwed onto the mouth portion 12a of the liquid container 12, and a circular opening 20b is formed on the top surface. Has been.

  The main body 22 is roughly projected in a lateral direction from a hat-shaped base portion 30 fixed to the mounting body 20, a first cylindrical portion 32 protruding from the top surface of the base portion 30, and a central wall portion of the first cylindrical portion 32. A second cylindrical portion 34. The axis of the first cylindrical portion 32 extends in a direction orthogonal to the central axis of the circular opening 20b, and the axis of the second cylindrical portion 34 is both on the axis of the first cylindrical portion 32 and the central axis of the circular opening 20b. It extends in the orthogonal direction.

  The base 30 passes through the circular opening 20b, and a plurality of small protrusions 30c (FIG. 3) are formed on the outer peripheral surface thereof. The small protrusions 30c are locked to the edge of the circular opening 20b. In this way, it is arranged and fixed inside and outside the attachment body 20. An inlet 30a is formed on the top surface of the base portion 30 so as to communicate with the inside of the first cylindrical portion 32 and to be able to communicate with the liquid container 12, and a partition wall is formed in the inlet 30a so as to cross the inlet 30a. 30b is formed. The partition 30b separates the inlet 30a into a first inlet 30a1 and a second inlet 30a2 (FIGS. 4 and 5).

  One end of the first cylindrical portion 32 is closed, the other end is open, and the inside is hollow. A fitting groove 32a (FIG. 3) is formed in the inner peripheral surface in the vicinity of the opened end portion, and a shaft body 24 described later is inserted from the opened end portion. Furthermore, a notch groove 32 b (FIG. 3) extending in an arc shape in the circumferential direction is formed at the opened end of the first cylindrical portion 32.

  One end portion of the second cylindrical portion 34 communicates with the first cylindrical portion 32, the other end portion serves as an outlet 34a, and a partition wall 34b is formed inside the second cylindrical portion 34 along the axial direction. By the partition wall 34b, the outlet 34a is separated into a first outlet 34a1 and a second outlet 34a2 (FIG. 4), and in the second cylindrical portion 34, a first channel 40 and a second channel 42 (FIG. 4). And separated.

  The partition wall 34b is completely non-porous and does not need to completely separate the first flow path 40 and the second flow path 42, and a slit 34c may be formed as in the illustrated example. The slit 34c gradually changes from the outlet 34a toward one end of the second cylindrical portion 34, that is, toward the back, from the wide to the narrow. The slit 34c integrates a core pin for forming the first flow path 40 and the second flow path 42 when the main body 22 is formed, thereby preventing the eccentricity of the core pin. The core pin corresponding to the slit leads to the outlet 34a. This is for pouring molten resin to become the partition wall 34b. However, the slit 34c can be omitted.

  Next, referring to FIG. 3 to FIG. 6, the shaft body 24 roughly includes a shaft portion 36 inserted into the first cylindrical portion 32 and a cock portion 38 disposed outside the first cylindrical portion 32. Prepare.

  A fitting protrusion 36 a (FIG. 3) that fits in the fitting groove 32 a of the first cylindrical portion 32 is formed on the shaft portion 36. A cutout portion 36b that is largely cut off from the side surface of the shaft is formed in the axially central portion excluding both ends of the shaft portion 36. As shown in FIG. 4, the cross-sectional shape of the notch 36b has an arc shape, and the wall defining the notch 36b is a curved partition wall 36c.

  Furthermore, a groove is formed on the side opposite to the side facing the notch 36b of the curved partition wall 36c. That is, the groove extends in the circumferential direction, and the groove bottom is a curved partition wall 36c. The groove is composed of a continuous first groove 36d having a long length and a wide second groove 36e having a short length and a narrow width. The cross-sectional area of the second groove 36e is smaller than the cross-sectional area of the first groove 36d.

  Further, ribs 36f having a low height extending in the circumferential direction are formed on both sides in the axial direction of the notch portion 36b of the shaft portion 36, and between the notch portion 36b and the first groove 36d and between the notch portion 36b and the second groove. A rib 36g having a low height extending in the axial direction is formed between the rib 36f and the rib 36g.

  As shown in FIG. 7, when the shaft portion 36 is inserted into the first cylindrical portion 32, the first cylindrical portion 32 is opened by the curved partition wall 36c in the open state as will be described later (FIG. 7B). An inner cavity is defined by the third flow path 44 defined by the notch 36 b and the inner peripheral surface of the first cylindrical portion 32, and the first groove 36 d and the inner peripheral surface of the first cylindrical portion 32. Separated into four flow paths 46. The second groove 36e and the inner peripheral surface of the first cylindrical portion 32 form an orifice 48 having a smaller cross-sectional area than the cross-sectional area before and after that.

  The cock portion 38 includes a cock base portion 38a that protrudes from the first cylindrical portion 32 and continues to the shaft portion 36 in the axial direction, and a cock lever portion 38b that extends from the cock base portion 38a.

  A display indicating opening and closing is attached to the outer peripheral surface of the cock base 38a as necessary. In addition, a part of the base portion of the cock lever 38b is inserted into the notch groove 32b of the first cylindrical portion 32, and the shaft 24 is within the range in which the cock lever 38b moves through the notch groove 32b. It can be rotated with respect to 32, and its rotation angle is 90 degrees.

  In the pouring tool 10 configured as described above, as shown in FIG. 7A, in the state where the cock lever portion 38 b is arranged in parallel with the second cylindrical portion 34, the shaft body 24 is in the first rotation position. In this case, both ends of the curved partition wall 36c abut against the inner peripheral surface of the first cylindrical portion 32, and the inlet 30a and the outlet 34a are separated by the curved partition wall 36c, so that the pouring tool 10 is closed. At this time, the liquid tightness can be ensured by the ribs 36f and 36g reliably contacting the inner peripheral surface of the first cylindrical portion 32 (FIG. 8). By arranging the cock lever 38b in parallel with the second cylindrical portion 34, the cock lever 38b can be placed in a position where it is difficult to get in the way when closed.

  On the other hand, as shown in FIG. 7B, in the state where the cock lever portion 38b is perpendicular to the second cylindrical portion 34, the shaft body 24 is in the second rotation position, and the curved partition wall 36c is the partition wall. 30b and the partition wall 34b. As a result, the first inlet 30a1, the third channel 44, the first channel 40, and the first outlet 34a1 communicate with each other to form a liquid channel, and the second inlet 30a2, the fourth channel 46, and the orifice 48, the 2nd flow path 42, and the 2nd exit 34a2 connect, and comprise the flow path for air, and the extraction tool 10 will be in an open state.

  When setting the outlet 34a to face downward and the liquid flow path to be below the air flow path in the opened state of the dispensing tool 10, the liquid is the liquid as shown in FIG. 9 (a). It passes through the flow path and flows out from the first inlet 30a1 to the first outlet 34a1. At the same time, since the liquid enters the air flow path, it flows out from the second inlet 30a2 to the second outlet 34a2. However, since the orifice 48 is formed in the air flow path, the second flow path 42 is not filled with the liquid by the orifice 48, and the liquid and air are mixed, and the vicinity of the orifice 48 The second flow path 42 is in an air release state.

  When the liquid is poured out from the liquid container 12 to some extent and the pressure in the liquid container 12 is reduced, the flow rate of the liquid from the liquid channel decreases. Since the pressure difference before and after the orifice 48 is also reduced, the flow rate of the liquid from the orifice 48 is also reduced.

  When the pressure difference across the orifice 48 is reversed, as shown in FIG. 9B, air existing in the second flow path 42 can enter the fourth flow path 46 from the orifice 48 (FIG. 9 ( b), an air flow is indicated by a broken line), and an air flow path that reaches the internal space in the liquid container 12 through the fourth flow path 46 is formed. Therefore, the internal pressure in the liquid container 12 is ensured, and the liquid flow from the liquid flow path can be maintained as it is.

  If the orifice 48 is not provided, the pressure of the liquid in the dispenser drops below the atmospheric pressure due to a decrease in the internal pressure in the liquid container 12, and the flow of the liquid is stopped. An air flow can be generated by a pressure difference of around 48, and the air is sequentially taken into the liquid container 12 using this as a trigger, so that the internal pressure can be increased, and thus the liquid flow is maintained. can do.

  The fourth flow path 46 has an effect of generating a pressure loss for reducing the pressure of the liquid before the orifice 48. Therefore, the fourth flow path 46 is preferably long to some extent and has a small cross-sectional area to some extent. This is because, in the case of a straight pipe, the pressure loss is inversely proportional to the fifth power of the diameter and proportional to the first power of the length.

  Furthermore, in the pouring tool 10, the curved partition wall 36 c is curved in the liquid flow path constituted by the first inlet 30 a 1, the third flow path 44, the first flow path 40, and the first outlet 34 a 1. The flow along the curved surface can be constituted. That is, since the directions of the surfaces of the inlet 30a and the outlet 34a are different from each other by 90 °, it is necessary to change the direction in the fluid flow path, but because the curved partition wall 36c exists at the point where the direction is changed. The direction can be gradually changed by the curved surface. In such a curved partition wall 36c, the central axis of the shaft body 24 on which the curved partition wall 36c is formed extends in a direction orthogonal to the normal to each surface of the inlet 30a and the outlet 34a, and the central axis thereof This can be realized by adopting a configuration that rotates around.

  On the other hand, in the configuration of the prior art, such a curved partition wall 36c cannot be formed, and a portion that is bent at right angles to the partition wall is always formed. In such a portion that bends at a right angle, air retention is formed, and fluid reflection and eddy currents are generated to inhibit smooth flow.

  FIG. 10 is a fluid analysis example showing a comparison between the dispensing tool 10 according to the present embodiment and the dispensing tool described in Japanese Patent Application No. 2008-9833. In the figure, the white part represents air, the black part represents liquid, and the ratio of liquid increases as it becomes darker.

  According to the dispensing tool according to the present embodiment, the curved surface is formed on the upper side by the curved partition wall 36c and the curved surface is formed on the lower side by the first cylindrical portion 32 in the portion corresponding to the third flow path. Since the fluid flows along this upper curved surface, as shown in FIG. 10A, it can be seen that there is no stagnation of air, reflection of fluid, and generation of vortex flow in this vicinity, and the fluid flows smoothly. Further, it can be seen that the fluid flows along the wall surface of the second cylindrical portion 34 due to the lower curved surface. On the other hand, when a portion that bends at a right angle is formed as in the prior art, the liquid does not flow smoothly near the upper right angle portion as shown in FIG. It can be seen that the liquid flow is separated from the wall surface of the second cylindrical portion 34 due to the lower right angle portion, and as a result, the cross sectional area of the liquid is small and the flow rate is small.

  In order to further support the above comparison, a pouring tool corresponding to the present embodiment (Example), a pouring tool corresponding to Patent Document 1 (Comparative Example 1), and a pouring tool corresponding to Japanese Patent Application No. 2008-9833 (Comparative Example) For 2), in the state where each is attached to the same liquid container 12 (filled with 5 L of water in a capacity of 5 L), it is necessary to dispense from the start of dispensing until 16 seconds later (FIG. 11) and to completely dispense 5 L. Time (Figure 12) was determined. The diameter of the outlet was the same for all pouring tools.

  As shown in FIG. 11 and FIG. 12, it can be seen that the embodiment has a larger amount of extraction and shorter extraction time than other extraction tools. About 8 seconds after the start of dispensing, an air flow through the air flow path is formed. Comparative Example 1 and Comparative Example 2 are substantially the same in terms of the amount and time of dispensing, but in Comparative Example 2, pulsation occurs once the air flow in the air channel is formed due to the effect of the orifice. Although the flow did not occur, in Comparative Example 1, even after the air flow through the air flow path was formed, the air flow was not stabilized and pulsation occurred.

  In the example, it was found that a large flow rate of liquid could be dispensed without causing pulsation.

  In the embodiment described above, the shaft body 24 is rotatable with respect to the first cylindrical portion 32, and thereby, the pouring tool 10 can be switched between the closed state and the open state. However, the shaft body 24 is fixed to the first cylindrical portion 32 so as not to be rotatable, and can always be kept open. In this case, a cap capable of closing the outlet 34a can be provided separately or separately from the pouring tool 10.
