Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
<< First Embodiment >>
First, the liquid dispenser according to the first embodiment of the present invention will be described. The liquid dispenser according to the first embodiment corresponds to a so-called Goebel top type (gable roof type) paper container. FIG. 1 is a perspective view of a liquid dispenser according to the first embodiment of the present invention. FIG. 2 is a side view of the liquid dispenser according to the first embodiment of the present invention. 1 and 2 show the liquid dispenser according to the present embodiment in a state of being mounted on a Goebel top type paper container. As shown in FIGS. 1 and 2, the liquid dispenser according to the present embodiment is used in a state of being mounted on a Goebel top type paper container.

As shown in FIGS. 1 and 2, the liquid dispenser of the present embodiment has an inflow part 1 for inflowing a liquid, a storage part 2 for storing the liquid, and a connecting part for connecting the inflow part 1 and the storage part 2. 3 and a pouring unit 4 which is connected to the storage unit 2 and for pouring out the liquid are provided. The inflow part 1, the storage part 2, the connecting part 3, and the pouring part 4 are integrally molded with a transparent resin. The inside of the liquid dispenser is hollow, and the liquid flows from the insertion portion 7 having an opening continuously formed on the tip end side of the inflow portion 1 to the injection port which is the opening formed in the injection portion 4. It is designed to flow. In the present specification, the liquid means a substance in a state other than a gas or a solid regardless of the degree of viscosity.

The paper container KG used in the present embodiment is of the type used for commercially available beverage containers and the like, and a plastic spout is formed on one of the two upper surfaces of the top of the Goebel top type. .. The spout of the paper container KG has a cylindrical shape, and a screw thread is formed on the outer surface side of the tubular spout, and it can be screwed into a cap 6 having a screw groove on the inner surface side. At the time of manufacture, the spout KGc and the cap 6 are integrally molded, and a part of the spout KGc and the cap 6 are formed in a continuous state and mounted on the paper container KG. In that state, after filling the liquid as the content, the product is sold, and after the purchase, the consumer opens the cap 6 by separating it from the spout KGc. As a result, the liquid that is the contents of the paper container KG can be poured out from the spout KGc. As the contents of such a paper container KG, various liquids such as beverages, seasonings, oils and fats, and liquid detergents are stored.

The coupling ring 5 is a member for binding the liquid dispenser to the paper container KG. The coupling ring 5 has substantially the same size as the cap 6 and has the same structure as the cap 6, but has an opening formed on the top surface side and has a cylindrical shape as a whole. The coupling ring 5 has a thread groove having the same specifications as the cap 6 formed on the inner surface side of the cylinder, and can be screwed into the spout of the paper container KG like the cap 6.

FIG. 3 is a cross-sectional view showing the state of connection between the spout of the paper container and the connection ring. As shown in the side view of FIG. 3, an insertion portion 7 is formed on the opening side of the inflow portion 1 via the locking portion 8. The tubular insertion portion 7 has a smaller outer diameter and inner diameter than the inflow portion 1. The outer diameter of the insertion portion 7 is slightly smaller than the inner diameter of the spout KGc, and the insertion portion 7 can be inserted into the spout KGc. The locking portion 8 located between the inflow portion 1 and the insertion portion 7 has a larger outer diameter than the inflow portion 1 and a smaller inner diameter than the inflow portion 1. The inner diameter of the locking portion 8 is the same as the inner diameter of the inserting portion 7. Therefore, inside the cylinder, the insertion portion 7 and the locking portion 8 are continuous with the same inner diameter, and the inner diameter is widened at the inflow portion 1.

The outer diameter of the locking portion 8 is larger than the outer diameter of the inflow portion 1 as described above, thereby preventing the coupling ring 5 from coming off. On the inner surface side of the coupling ring 5, a convex portion parallel to the top surface of the coupling ring 5 and protruding toward the inner surface is formed. The inner diameter of the convex portion is substantially the same as the inner diameter of the opening formed on the top surface of the coupling ring 5. Further, the inner diameter between the top surface and the convex portion of the coupling ring 5 is slightly larger than the outer diameter of the locking portion 8. Therefore, the coupling ring 5 is prevented from coming off from the locking portion 8.

Since the state near the coupling ring 5 has a configuration as shown in the cross-sectional view of FIG. 3, after removing the cap 6 from the paper container KG, the insertion portion 7 is inserted inside the spout KGc of the paper container KG and bonded. By screwing the ring 5 with the outer surface of the spout KGc, the insertion portion 7 and the locking portion 8 are fixed to the spout KGc, and the liquid dispenser is attached to the paper container KG. The state of being mounted in this way is the state shown in FIGS. 1, 2, and 3.

As shown in FIGS. 1, 2 and 3, the inflow portion 1 is fixed to the paper container KG via the coupling ring 5 and is a flow path for flowing the liquid from the paper container KG. The storage section 2 has the maximum volume and is a section for storing the liquid that has flowed in from the paper container KG. The connecting portion 3 is a flow path that connects the inflow portion 1 and the storage portion 2, and allows the liquid that has flowed in from the inflow portion 1 to flow to the connecting portion 3. The dispensing section 4 is a flow path that is continuous from the storage section 2 and for pouring out the liquid stored in the storage section 2 to the outside. At the tip of the ejection portion 4 on the opening side, a screw thread having the same specifications as the injection port of the paper container KG is formed on the outer surface side thereof, and the cap 6 attached to the paper container KG can be screwed and attached. It has become.

As shown in FIG. 2, when the Goebel top type paper container KG is placed upright on a horizontal plane, in a preferred embodiment, the extension direction of the connecting portion 3 is the horizontal direction in the liquid dispenser mounted on the paper container KG. .. Since the connecting portion 3 is a flow path that connects the inflow portion 1 and the storage portion 2, the direction in which the inflow portion 1 and the storage portion 2 are connected is the extending direction of the connecting portion 3. In the side view of FIG. 2, the extension direction DA of the connecting portion 3 is indicated by an arrow of a dotted chain line pointing to the right passing through the center of the connecting portion 3.

The dispensing portion 4 is a tubular portion having a circular opening on the upper end side. The liquid is dispensed from the dispensing portion 4 through the inside of the cylinder. Therefore, the pouring direction of the pouring portion 4 is a direction orthogonal to the opening surface on the upper end side. In the side view of FIG. 2, the pouring direction DB of the pouring portion 4 is indicated by an arrow of a dotted chain line pointing to the upper right passing through the center of the pouring portion 4. In the side view of FIG. 2, the extension direction DC of the bottom surface 2b of the storage unit 2 is indicated by an arrow of a dash-dotted line pointing downward to the right passing through the lower end of the bottom surface 2b of the storage unit 2.

The storage portion 2 is surrounded by a plurality of side surfaces, and the extending direction of the first side surface 2a, which is one of the side surfaces, is parallel to the pouring direction DB of the pouring portion 4. Since the stretching direction of the first side surface 2a is parallel to the pouring direction DB of the pouring portion 4, the pouring portion is provided from the first side surface 2a when the paper container KG and the liquid pouring tool are tilted at the time of pouring. The liquid will flow smoothly toward 4.

The pouring direction DB of the pouring portion 4 is tilted by a predetermined angle with respect to the stretching direction DA of the connecting portion 3. Specifically, the pouring direction DB of the pouring portion 4 is inclined in a direction away from the connecting portion 3 with respect to the direction DE orthogonal to the extending direction DA of the connecting portion. That is, the angle RE formed by the pouring direction DB of the pouring portion 4 and the direction DE orthogonal to the extending direction DA of the connecting portion is 0 ° or more. Here, if the angle formed by the dispensing direction DB of the dispensing portion 4 and the stretching direction DA of the connecting portion 3 is RA, RA + RE = 90 °. Therefore, the angle RE is determined by the angle RA formed by the pouring direction DB of the pouring portion 4 and the stretching direction DA of the connecting portion 3.

That is, the connecting portion 3 and the dispensing portion 4 are formed so that the angle RA formed by the pouring direction DB of the pouring portion 4 and the extending direction DA of the connecting portion 3 is a predetermined angle. The angle RA formed by the pouring direction DB of the pouring portion 4 and the stretching direction DA of the connecting portion 3 is preferably 40 ° or more and 80 ° or less, and particularly preferably 50 ° or more and 70 ° or less. In this embodiment, the angle RA = 60 °. Therefore, the angle RE formed by the pouring direction DB of the pouring portion 4 and the direction DE orthogonal to the extending direction DA of the connecting portion is preferably 10 ° or more and 50 ° or less, and particularly 20 ° or more and 40 ° or less. It is preferable to have. In this embodiment, the angle RE = 30 °. In a preferred design, when the paper container KG equipped with the liquid dispensing tool is placed, the dispensing direction DB of the dispensing portion 4 is the horizontal direction, and the direction DE orthogonal to the extending direction DA of the connecting portion is the vertical direction. Become.

If the angle RA is too small (that is, the angle RE is too large), the cap 6 side protrudes greatly in the horizontal direction from the side surface of the paper container KG, which tends to be an obstacle when the liquid dispenser is attached and stored. The horizontal balance becomes poor and the paper container KG tends to fall over. If the angle RA is too large (that is, the angle RE is too small), the pouring direction DB of the pouring portion 4 approaches directly above, and when the liquid is pouring out with the liquid pouring tool attached, it is vertically long. It becomes necessary to rotate the paper container KG 180 ° and keep it tilted so that the Goebel top faces straight down, which makes it difficult to handle.

The bottom surface 2b of the storage unit 2 is a surface to be placed on one of the two upper surfaces of the Goebel top type paper container KG. The position is determined by placing the bottom surface 2b on one upper surface of the paper container KG. In order to make the fixed state more stable, the stretching direction DC of the bottom surface 2b needs to be parallel to one of the two upper surfaces of the paper container KG. Since the stretching direction DC of the bottom surface 2b is parallel to one of the two upper surfaces of the paper container KG, the weight of the storage unit 2 is dispersed and hung on the upper surface of the paper container KG even when the liquid is stored. , The load is small for both the paper container KG and the storage unit 2.

The stretching direction DC of the bottom surface 2b of the storage portion 2 is a direction inclined by a predetermined angle with respect to the stretching direction DA of the connecting portion 3. That is, the bottom surface 2b of the connecting portion 3 and the storage portion 2 is formed so that the angle RB formed by the stretching direction DA of the connecting portion 3 and the stretching direction DC of the bottom surface 2b of the storage portion 2 is a predetermined angle. On the other hand, the two upper surfaces of the paper container KG are formed so that the angle formed by the horizontal direction is RD. When the angle RB formed by the stretching direction DA of the connecting portion 3 and the stretching direction DC of the bottom surface 2b of the storage portion 2 and the angle RD formed by one of the upper surfaces of the paper container KG and the horizontal direction are equal, that is, when RB = RD. The entire bottom surface 2b is placed in contact with the upper surface of the paper container KG, and the fixed state is stabilized. Further, that is, when RB = RD, the stretching direction DA of the connecting portion 3 is the horizontal direction.

The inflow portion 1 is inserted into the opening of the spout KGc formed on the first upper surface KGa side of the paper container KG. As described above, the insertion portion 7 and the locking portion 8 are continuous at the tip of the inflow portion 1, and the extension direction of the insertion portion 7 is the liquid inflow direction DD, which is the inflow direction DD of the inflow portion 1. And. The angle formed by the inflow direction DD of the inflow portion 1 and the lower end surface of the coupling ring 5 is formed to be 90 °. On the other hand, in order to firmly bring the coupling ring 5 and the first upper surface KGa of the paper container KG into close contact with each other, it is preferable that the lower end surface of the coupling ring 5 and the first upper surface KGa of the paper container KG are parallel to each other. Therefore, it is preferable that the angle formed by the inflow direction DD of the inflow portion 1 and the first upper surface KGa is 90 degrees. For this purpose, the angle RC formed by the stretching direction DA of the connecting portion 3 and the inflow direction DD of the inflow portion 1 is preferably the sum of the angle RD formed by the upper surface of the paper container KG and the horizontal direction and 90 °. .. That is, it is preferable that RC = RD + 90.

The liquid dispenser is designed according to the aspect of the upper surface of the paper container KG. Specifically, according to the angle RD formed by the two upper surfaces of the Goebel top type paper container KG with the horizontal plane, the extension direction DA of the connecting portion 3, the dispensing direction DB of the dispensing portion 4, and the bottom surface 2b of the storage portion 2 The extension direction DC and the inflow direction DD of the inflow part 1 are determined, and the connecting part 3, the pouring part 4, the storage part 2, and the inflow part 1 are designed. At this time, the extension direction DA of the connecting portion 3, the injection direction DB of the injection portion 4, the extension direction DC of the bottom surface 2b of the storage portion 2, and the inflow direction DD of the inflow portion 1 are determined based on the angles RA to RC. NS.

The angles RA to RC of the liquid dispenser are determined based on the angle RD formed by the upper surface of the target paper container KG with the horizontal plane. Therefore, a preferable liquid dispenser can be obtained by configuring each component so that RB = RD and RC = RD + 90. Further, the angles RB and RC do not necessarily have to satisfy the above relationship with the angles RD exactly, and some errors are allowed. Specifically, an error of up to 5 ° is acceptable. Therefore, when RD = 40 °, it can be realized in the range of RA = 35 ° to 85 °, RB = 35 ° to 45 °, and RC = 125 ° to 135 °. The angle RD of the upper surface of the paper container KG differs depending on the product specifications, but generally, RD = 30 ° to 50 °. Therefore, by designing RA = 35 ° to 85 °, RB = 25 ° to 55 °, and RC = 115 ° to 145 °, it can be applied to and mounted on various commercially available paper containers KG. When the paper container KG is placed, the stretching direction DA of the connecting portion 3 becomes close to horizontal, and when the paper container KG is rotated, it becomes possible to provide a liquid dispenser that easily flows in and easily dispenses. ..

<< Modified example of the first embodiment >>
In the first embodiment, the connecting portion 3 has a cylindrical shape. That is, the form in which the cross section of the connecting portion 3 intersecting the stretching direction DA of the connecting portion 3 is circular has been described. Next, a modified example of the liquid dispenser according to the first embodiment will be described. FIG. 4 is a perspective view showing a modified example of the liquid dispenser according to the first embodiment. The same parts as those of the liquid dispenser shown in FIGS. 1 and 2 are designated by the same reference numerals and the description thereof will be omitted.

In the modified example, as in the first embodiment, the liquid dispenser includes an inflow portion 1 for inflowing the liquid, a storage portion 2 for storing the liquid, and a connecting portion for connecting the inflow portion 1 and the storage portion 2. 3 and a pouring section 4 for pouring a liquid continuously from the storage section 2 are provided. Further, the angles RA to RC of the liquid dispenser are determined based on the angle RD formed by the upper surface of the target paper container KG with the horizontal plane, and when the angle RD of the paper container KG is 30 ° to 50 °, the RA is determined. Similarly, 35 ° to 65 °, RB of 25 ° to 55 °, and RC = 115 ° to 145 ° are preferable.

In the modified example, the cross-sectional shape of the connecting portion 3 is substantially rectangular, and the pouring portion 4 protrudes from the upper end of the storage portion 2, which is different from the first embodiment. The connecting portion 3 need only have a predetermined cross-sectional area for smooth flow of the liquid, and does not have to be circular as shown in FIG. 1, and has a rectangular shape as shown in the modified example of FIG. It may be a rectangular shape or other polygon such as. In order to fit the circular coupling ring 5, the cross section of the insertion portion 7 and the locking portion 8 is circular even in the modified example. Therefore, the inflow portion 1 also has a circular cross section in the portion close to the locking portion 8, but changes smoothly from there and is the same as the cross-sectional shape of the connecting portion 3 in the portion continuous with the connecting portion 3. It has a cross-sectional shape.

Further, in the modified example shown in FIG. 1, the tubular body portion of the dispensing portion 4 protrudes from the upper end of the storage portion 2. Comparing the case where the tubular body portion of the dispensing portion 4 does not protrude and the case where it protrudes as in the first embodiment, there are advantages and disadvantages. When the tubular body portion of the dispensing portion 4 does not protrude as in the first embodiment, the whole can be accommodated relatively compactly, and space can be saved with the liquid dispensing tool fitted. There are advantages. On the other hand, when the tubular body portion of the dispensing portion 4 protrudes as in the modified example, there is an advantage that the dispensing destination can be easily determined.

<< How to use in the first embodiment >>
A method of using the liquid dispenser according to the first embodiment shown in FIG. 1 will be described. FIG. 5 is a diagram showing a method of using the liquid dispenser according to the first embodiment. When acquiring a certain amount of contents using the liquid dispenser according to the first embodiment, the cap 6 is removed from the Goebel top type paper container KG provided with the spout KGc. Then, the insertion portion 7 continuous from the inflow portion 1 via the locking portion 8 is inserted inside the spout KGc of the paper container KG. Then, the screw groove of the coupling ring 5 rotatably fitted to the locking portion 8 and the screw thread on the outer surface of the spout KGc of the paper container KG are screwed together to mount the coupling ring 5. On the other hand, the cap 6 removed from the paper container KG is attached to the liquid dispenser by screwing the screw groove of the cap 6 and the screw thread on the outer surface of the spout KGc of the dispenser 4 of the liquid dispenser. At this time, since the angles RA to RC are appropriately determined based on the angle RD, the entire liquid dispenser is stably fixed on the upper surface of the Goebel top of the paper container KG. That is, as shown in FIG. 5A, the entire liquid dispenser is stably fixed on the two upper surfaces of the Goebel top of the paper container KG.

From the state shown in FIG. 5A, the liquid dispenser is rotated by approximately 180 ° together with the paper container KG so that the Goebel top of the liquid dispenser and the paper container KG faces downward. FIG. 5B shows a state in which the gobel top of the liquid dispenser and the paper container KG is directed downward. As shown in FIG. 5B, with the gobel top of the liquid dispenser and the paper container KG facing downward, the contents flow out from the injection port of the paper container KG facing downward, and the liquid dispenser is inserted. It flows into the inflow section 1 through the section 7 and the locking section 8. Then, the liquid that has flowed into the inflow section 1 further flows into the storage section 2 through the connecting section 3. Then, from the state shown in FIG. 5B, the liquid dispenser and the paper container KG are returned so as to face upward by further rotating. In this process, the pouring outlet KGc of the paper container KG does not face downward, and at that point, the inflow of the liquid from the paper container KG into the liquid dispenser stops.

Further rotate and make one rotation, and return the liquid dispenser and the paper container KG to their original positions so that the Goebel top is facing upward. FIG. 5 (c) is a diagram showing a state in which one rotation is performed and the position is returned to the same position as in FIG. 5 (a). As shown in FIG. 5C, after one rotation, the liquid flowing from the paper container KG is stored in the storage unit 2. In the present embodiment, the angles RA to RC corresponding to the above angle RD are appropriately designed, so that the paper container KG is placed so that the Goebel top is on the upper side, and the extension direction DA of the connecting portion 3 is DA. Becomes almost horizontal. Therefore, after one rotation, the liquid remaining in the liquid dispenser returns to the inside of the paper container KG from the inflow unit 1 through the injection port of the paper container KG, or is stored in the storage unit 2. In the storage unit 2, the liquid is stored in a portion lower than the connecting unit 3. By designing the portion of the storage unit 2 that is lower than the connecting portion 3 to have a predetermined volume, a predetermined amount of liquid is stored in the storage unit 2.

Then, as shown in FIG. 5D, the liquid dispenser is tilted with the cap 6 removed from the outlet of the dispenser 4 of the liquid dispenser. As a result, a predetermined amount of liquid stored in the liquid dispenser is dispensed. As described with reference to FIG. 5, in the liquid dispenser according to the present embodiment, the user simply rotates the liquid dispenser once together with the paper container KG without performing the work of measuring the amount of the liquid. A predetermined amount of liquid can be poured into the dispenser.

<< Second Embodiment >>
Next, the second embodiment will be described. FIG. 6 is a side view of the liquid dispenser according to the second embodiment of the present invention. FIG. 6 shows the liquid dispenser according to the present embodiment in a state of being attached to the paper container KF.

As shown in FIG. 6, the liquid dispenser of the present embodiment includes an inflow section 11 for inflowing a liquid, a storage section 12 for storing the liquid, and a connecting section 13 for connecting the inflow section 11 and the storage section 12. It is provided with a pouring unit 14 continuous from the storage unit 12 and for pouring out the liquid. The inflow section 11, the storage section 12, the connecting section 13, and the dispensing section 14 are integrally molded with a transparent resin as in the first embodiment. Similar to the first embodiment, the inside of the liquid dispenser is hollow, and the liquid is from the inlet which is the opening formed in the inflow portion 11 to the inlet which is the opening formed in the dispenser 14. Can flow.

The paper container KF used in this embodiment is of the type used for commercially available beverage containers and the like, and is made of plastic on a flat top type top, that is, a flat upper surface parallel to a horizontal plane when placed. The spout KFc is formed. The spout KFc of the paper container KF has a cylindrical shape, and a thread is formed on the outer surface side of the tubular spout KFc, and it can be screwed into a cap 16 having a thread groove on the inner surface side. .. At the time of manufacturing, the spout and the cap 16 are integrally molded, and a part of the cap 16 is formed in a continuous state and mounted on the paper container KF. In that state, the contents are filled and then sold, and after purchase, the consumer opens the cap 16 by separating it from the spout KFc. This makes it possible to pour out the contents of the paper container KF from the spout KFc.

The coupling ring 15 is a member for coupling the liquid dispenser with the paper container KF. The coupling ring 15 has substantially the same size as the cap 16 and has the same structure as the cap 16, but has an opening formed on the top surface side and has a cylindrical shape as a whole. The coupling ring 15 has a thread groove having the same specifications as the cap 16 formed on the inner surface side of the cylinder, and can be screwed into the spout KFc of the paper container KF like the cap 16.

FIG. 7 is a cross-sectional view showing the relationship between the coupling ring 15 and the spout KFc when the liquid dispenser is mounted on the paper container KF. As shown in FIG. 7, an insertion portion 17 is formed on the opening side of the inflow portion 11 via the locking portion 18. The tubular insertion portion 17 has a smaller outer diameter and inner diameter than the inflow portion 11. The outer diameter of the insertion portion 17 is slightly smaller than the inner diameter of the spout KFc, and the insertion portion 17 can be inserted into the spout KFc. The locking portion 18 located between the inflow portion 11 and the insertion portion 17 has a larger outer diameter than the inflow portion 11 and a smaller inner diameter than the inflow portion 1. The inner diameter of the locking portion 18 is the same as the inner diameter of the inserting portion 17. Therefore, inside the cylinder, the insertion portion 17 and the locking portion 18 are continuous with the same inner diameter, and the inner diameter is widened at the inflow portion 11.

As described above, the outer diameter of the locking portion 18 is larger than the outer diameter of the inflow portion 11, which prevents the coupling ring 15 from coming off. On the inner surface side of the coupling ring 15, a convex portion that is parallel to the top surface of the coupling ring 15 and projects toward the inner surface side is formed. The inner diameter of the convex portion is substantially the same as the inner diameter of the opening formed on the top surface of the coupling ring 15. Further, the inner diameter between the top surface and the convex portion of the coupling ring 15 is slightly larger than the outer diameter of the locking portion 18. Therefore, the coupling ring 15 is prevented from coming off from the locking portion 18.

Since the configuration is as described above, after removing the cap 16 from the paper container KF, the insertion portion 17 is inserted inside the spout KFc of the paper container KF, and the coupling ring 15 is screwed with the outer surface of the spout KFc. As a result, the insertion portion 17 and the locking portion 18 are fixed to the spout KFc, and the liquid pouring tool is attached to the paper container KF. This is the state shown in FIG.

As shown in FIG. 6, the inflow portion 11 is fixed to the paper container KF via the coupling ring 15 and is a flow path for flowing the liquid from the paper container KF. The storage unit 12 has the largest volume among the components and is a portion for storing the liquid flowing in from the paper container KF. The connecting portion 13 is a flow path that connects the inflow portion 11 and the storage portion 12, and allows the liquid that has flowed in from the inflow portion 11 to flow to the connecting portion 13. The dispensing section 14 is a flow path that is continuous from the storage section 12 and for pouring out the liquid stored in the storage section 12 to the outside. A screw thread having the same specifications as the injection port KFc of the paper container KF is formed on the outer surface side of the opening-side tip of the dispensing portion 14, and the cap 16 attached to the paper container KF is screwed and attached. It is possible.

As shown in FIG. 6, when the flat-top type paper container KF is placed upright on a horizontal surface, in a preferred embodiment, the extension direction of the connecting portion 13 is the horizontal direction in the liquid dispenser mounted on the paper container KF. .. Since the connecting portion 13 is a flow path that connects the inflow portion 11 and the storage portion 12, the direction in which the inflow portion 11 and the storage portion 12 are connected is the extending direction of the connecting portion 13. In the side view of FIG. 6, the extension direction DG of the connecting portion 13 is indicated by an arrow of a dotted chain line pointing to the right passing through the center of the connecting portion 3.

The dispensing portion 14 is a cylindrical portion having a circular opening on the upper end side. The liquid is dispensed from the dispensing portion 14 through the inside of the cylinder. Therefore, the pouring direction of the pouring portion 14 is a direction orthogonal to the opening surface on the upper end side. In the side view of FIG. 6, the pouring direction DH of the pouring portion 14 is indicated by an arrow of a dotted chain line pointing to the upper right passing through the center of the pouring portion 14. In the side view of FIG. 6, the extension direction DI of the bottom surface 12b is indicated by an arrow of a dash-dotted line pointing downward to the right passing through the lower end of the bottom surface 12b.

The storage portion 12 is surrounded by a plurality of side surfaces, and the extending direction of the first side surface 12a thereof is parallel to the pouring direction DH of the pouring portion 14. Since the stretching direction of the first side surface 12a is parallel to the pouring direction DH of the pouring portion 14, when the paper container KF and the liquid pouring tool are tilted at the time of pouring, the pouring portion is provided from the first side surface 12a. The liquid will flow smoothly toward 14.

The pouring direction DH of the pouring portion 14 is tilted by a predetermined angle with respect to the stretching direction DG of the connecting portion 13. Specifically, the pouring direction DH of the pouring portion 14 is inclined in a direction away from the connecting portion 13 with respect to the direction DK orthogonal to the extending direction DG of the connecting portion. That is, the angle RK formed by the pouring direction DH of the pouring portion 14 and the direction DK orthogonal to the extending direction DG of the connecting portion is 0 ° or more. Here, assuming that the angle formed by the dispensing direction DH of the dispensing portion 14 and the stretching direction DG of the connecting portion 13 is RG, RG + RK = 90 °. Therefore, the angle RK is determined by the angle RG formed by the pouring direction DH of the pouring portion 14 and the stretching direction DG of the connecting portion 13.

That is, the connecting portion 13 and the pouring portion 14 are formed so that the angle RG formed by the pouring direction DH of the pouring portion 14 and the extending direction DG of the connecting portion 13 is a predetermined angle. The angle RG formed by the pouring direction DH of the pouring portion 14 and the stretching direction DG of the connecting portion 13 is preferably 40 ° or more and 80 ° or less, and particularly preferably 50 ° or more and 70 ° or less. In this embodiment, RG = 60 °. Therefore, the angle RK formed by the pouring direction DH of the pouring portion 14 and the direction DK orthogonal to the extending direction DG of the connecting portion is preferably 10 ° or more and 50 ° or less, and particularly at 20 ° or more and 40 ° or less. It is preferable to have. In this embodiment, the angle RK = 30 °. In a preferred design, when the paper container KF equipped with the liquid dispensing tool is placed, the dispensing direction DH of the dispensing portion 14 is the horizontal direction, and the direction DK orthogonal to the extending direction DG of the connecting portion is the vertical direction. Become.

If the angle RG is too small (that is, the angle RK is too large), the cap 16 side protrudes greatly in the horizontal direction from the wall surface of the paper container KF, which tends to be an obstacle when storing the paper container KF equipped with the liquid dispenser. At the same time, the balance in the horizontal direction becomes unbalanced and it becomes easy to fall down. If the angle RG is too large (that is, the angle RK is too small), the pouring direction of the pouring portion 14 approaches the direction directly above the DH, and when pouring the liquid with the liquid pouring tool attached, it is vertically long. It becomes necessary to rotate the paper container KF 180 ° and keep the flat top tilted so as to face directly downward, which makes it difficult to handle.

The bottom surface 12b of the storage unit 12 is a surface on which the bottom surface 12b of the Goebel top type paper container KF is placed on one of the two top surfaces. The position is determined by placing the bottom surface 12b on one upper surface of the paper container KF. In order to make the fixed state more stable, the stretching direction DI of the bottom surface 12b needs to be parallel to the upper surface of the paper container KF. Since the stretching direction DI of the bottom surface 12b is parallel to the upper surface of the paper container KF, the weight of the storage unit 12 is dispersed and hung on the upper surface of the paper container KF even when the liquid is stored, and the paper container KF. The load is small for both the storage unit 12 and the storage unit 12.

The stretching direction DI of the bottom surface 12b of the storage portion 12 is a direction substantially parallel to the stretching direction DG of the connecting portion 13. Here, "substantially" means not only when the storage portion 12 is completely parallel, but also when the storage portion 12 can be stably placed on the upper surface KFa of the paper container KF, and a smooth flow can be realized at the connecting portion 13. It also includes range errors. That is, the bottom surface 12b of the connecting portion 13 and the storage portion 12 is such that the angle formed by the stretching direction DG of the connecting portion 13 and the stretching direction DI of the bottom surface 12b of the storage portion 12 is 0 ° or a predetermined angle close to 0 °. Is formed. On the other hand, the upper surface of the paper container KF is parallel to the bottom surface of the paper container KF (not shown), and is formed so as to be parallel to the horizontal direction when the paper container KF is placed. That is, the angle RL (not shown) formed by the upper surface of the paper container KF and the horizontal direction is formed to be 0 °. When the stretching direction DG of the connecting portion 13, the stretching direction DI of the bottom surface 12b of the storage portion 12, and the upper surface of the paper container KF are parallel to each other, the entire bottom surface 12b is placed in contact with the upper surface of the paper container KF. The fixed state is stable. That is, when the stretching direction DG of the connecting portion 13, the stretching direction DI of the bottom surface 12b of the storage portion 12, and the upper surface of the paper container KF are parallel to each other, the stretching direction DG of the connecting portion 3 is the horizontal direction.

The inflow portion 11 is inserted into an opening formed on the upper surface KFa side of the paper container KF. As described above, the insertion portion 17 and the locking portion 18 are continuous at the tip of the inflow portion 11, and the extension direction of the insertion portion 17 is the liquid inflow direction DJ, which is the inflow direction DJ of the inflow portion 11. And. The angle formed by the inflow direction DJ of the inflow portion 11 and the lower end surface of the coupling ring 15 is formed to be 90 °. On the other hand, in order to firmly bring the coupling ring 15 and the upper surface KFa of the paper container KF into close contact with each other, it is preferable that the lower end surface of the coupling ring 15 and the upper surface KFa of the paper container KF are parallel to each other. Therefore, it is preferable that the angle formed by the inflow direction DJ of the inflow portion 11 and the upper surface KFa is 90 degrees. For this purpose, it is preferable that the angle RJ formed by the extension direction DG of the connecting portion 13 and the inflow direction DJ of the inflow portion 11 is also 90 °.

The liquid dispenser is designed according to the aspect of the upper surface of the paper container KF. Specifically, the stretching direction DG of the connecting portion 13, the pouring direction DH of the pouring portion 14, and the stretching of the bottom surface 12b of the storage portion 12 are adjusted according to the angle formed by the upper surface KFa of the flat top type paper container KF with the horizontal plane. The direction DI and the inflow direction DJ of the inflow section 11 are determined, and the connecting section 13, the pouring section 14, the storage section 12, and the inflow section 11 are designed. At this time, the extension direction DG of the connecting portion 13, the injection direction DH of the injection portion 14, the extension direction DI of the bottom surface 12b of the storage portion 12, and the inflow direction DJ of the inflow portion 1 are determined based on the angles RG and RJ. NS.

The angles RG and RJ of the liquid dispenser are determined based on the angle formed by the upper surface KFa of the target paper container KF with the horizontal plane. In the case of a flat-top type paper container KF, the upper surface KFa is usually parallel to the horizontal plane, and the angle formed by the upper surface KFa with the horizontal plane is usually 0 °. Therefore, a preferable liquid dispenser can be obtained by configuring each component so that the angle RG = 40 ° to 80 ° and RJ = 90 °. Further, the angle RJ does not necessarily have to be exactly 90 °, and some error is allowed. Specifically, an error of up to 5 ° is acceptable. Therefore, when the upper surface KFa of the paper container KF is parallel to the horizontal plane, the RG can be realized in the range of 35 ° to 85 ° and RJ = 85 ° to 95 °. The angle formed by the upper surface KFa of the paper container KF differs depending on the product specifications, but in general, in the case of the flat top type paper container KF, the angle formed by the horizontal surface is 0 ° to 10 °. Therefore, by designing RG = 35 ° to 85 ° and RJ = 75 ° to 105 °, it can be applied to various commercially available paper containers KF, and the paper container KF is mounted and mounted. At that time, the stretching direction DG of the connecting portion 3 becomes close to horizontal, and it is possible to provide a liquid dispenser that easily flows in and easily dispenses when rotated.

<< Modified example of the second embodiment >>
In the second embodiment, when the paper container KF is attached, the boundary portion between the connecting portion 13 and the dispensing portion 14 on the upper side has an angle. That is, the boundary portion between the connecting portion 13 and the pouring portion 14 is formed so as to have an angle RG formed by the pouring direction DH of the pouring portion 14 and the extending direction DG of the connecting portion 13. In the second embodiment, it is also possible to use a modification other than the above. Next, a modified example of the liquid dispenser according to the second embodiment will be described. FIG. 8 is a perspective view showing a modified example of the liquid dispenser according to the second embodiment. The same parts as those of the liquid dispenser shown in FIG. 6 are designated by the same reference numerals and the description thereof will be omitted.

In the modified example, as in the second embodiment, the liquid dispenser includes an inflow portion 11 for inflowing the liquid, a storage portion 12 for storing the liquid, and a connecting portion for connecting the inflow portion 11 and the storage portion 12. A 13 and a pouring unit 14 for pouring a liquid continuously from the storage unit 12 are provided. The angles RG and RJ of the liquid dispenser are determined based on the angle RL formed by the upper surface KFa of the target paper container KF with the horizontal plane, and the angle RL formed by the upper surface KFa of the paper container KF with the horizontal plane is 0 ° to 10 ° C. Similarly, in the case of °, the RG is preferably 35 ° to 85 ° and RJ = 75 ° to 105 °.

The modified example is different from the second embodiment in that the boundary portion between the connecting portion 13 and the dispensing portion 14 is continuous in a curved shape. The boundary portion between the connecting portion 13 and the pouring portion 14 may be configured to allow the liquid to flow smoothly, and is not limited to the modes shown in FIGS. 6 and 8, and may be in various modes other than these. can.

<< How to use in the second embodiment >>
A method of using the liquid dispenser according to the second embodiment shown in FIG. 6 will be described. FIG. 9 is a diagram showing a method of using the liquid dispenser according to the second embodiment. When acquiring a certain amount of contents using the liquid dispenser according to the first embodiment, the cap 16 is removed from the flat top type paper container KF provided with the spout. Then, the insertion portion 17 continuous from the inflow portion 11 via the locking portion 18 is inserted into the inside of the pouring outlet of the paper container KF. Then, the screw groove of the coupling ring 15 rotatably fitted to the locking portion 18 and the screw thread on the outer surface of the spout of the paper container KF are screwed together to mount the coupling ring 15. On the other hand, the cap 16 removed from the paper container KF is attached to the liquid dispenser by screwing the screw groove of the cap 16 and the screw thread on the outer surface of the outlet of the liquid dispenser 14. At this time, since the angles RG and RJ are appropriately determined based on the angles RD, the entire liquid dispenser is stably fixed on the upper surface KFa of the flat top of the paper container KF. That is, as shown in FIG. 9A, the entire liquid dispenser is stably fixed on the upper surface KFa of the flat top of the paper container KF.

From the state shown in FIG. 9A, the liquid dispenser is rotated by approximately 180 ° together with the paper container KF so that the flat top of the liquid dispenser and the paper container KF faces downward. FIG. 5B shows a state in which the flat top of the liquid dispenser and the paper container KF is directed downward. As shown in FIG. 5B, with the flat top of the liquid dispenser and the paper container KF facing downward, the contents flow out from the outlet of the paper container KF facing downward, and the liquid dispenser is inserted. It flows into the inflow portion 11 through the portion 17 and the locking portion 18. Then, the liquid that has flowed into the inflow section 11 further flows into the storage section 12 through the connecting section 13. Then, from the state shown in FIG. 9B, the liquid dispenser and the flat top of the paper container KF are returned so as to face upward as before by further rotating. In this process, the pouring outlet of the paper container KF does not face downward, and at that point, the inflow of the liquid from the paper container KF into the liquid dispenser stops.

Further rotate and make one rotation, and return it to the original position so that the flat top of the liquid dispenser and the paper container KF faces upward. FIG. 9 (c) is a diagram showing a state in which the product has been rotated once and returned to the same position as in FIG. 9 (a).

In the present embodiment, the angles RG and RJ corresponding to the above angle RL are appropriately designed, so that the connecting portion 13 is substantially horizontal with the paper container KF placed so that the flat top is on the upper side. Become. Therefore, after one rotation, the liquid remaining in the liquid dispenser returns to the inside of the paper container KF from the inflow unit 11 through the injection port KFc of the paper container KF, or is stored in the storage unit 12. In the storage unit 12, the liquid is stored in a portion lower than the connecting portion 13. By designing the portion of the storage unit 12 that is lower than the connecting portion 13 to have a predetermined volume, a predetermined amount of liquid is stored in the storage unit 12.

Then, as shown in FIG. 9D, the liquid dispenser is tilted with the cap 16 removed from the outlet of the dispenser portion 14 of the liquid dispenser. As a result, a predetermined amount of liquid stored in the liquid dispenser is dispensed. As described with reference to FIG. 9, in the liquid dispenser according to the present embodiment, the user simply rotates the liquid dispenser once together with the paper container KF without performing the work of measuring the amount of the liquid. A predetermined amount of liquid can be poured into the dispenser.
