Description

The present disclosure relates to dispensing containers.

BACKGROUND ART Dispensing containers capable of discharging liquid contents such as food seasonings such as soy sauce, beverages, shampoos, conditioners, body soaps, cosmetics, or medicines are known. As described in Patent Document 1, for example, such a discharge container includes a container body having a mouth portion, a discharge cap attached to the mouth portion, and the discharge cap includes a valve body and a valve body. It may include a discharge cylinder having a seating part for seating and a valve holding part disposed above the seating part. According to such a dispensing container, by tilting the dispensing container, the valve body is brought into contact with and held by the valve holding part, and the contents are squeezed between the valve disc and the dispensing cylinder by its own weight or by squeezing (pressing) the container body. It is possible to discharge from the discharge port of the discharge cylinder through the gap between the two. Further, by returning the discharge container to the upright position, the discharge of the contents is stopped, the valve element is lowered from the valve holding part toward the seating part, and the remaining liquid in the discharge cylinder is pulled back. By pulling back the remaining liquid (suck back), dripping of the liquid from the discharge port is suppressed. Moreover, since the valve body is seated on the seating portion, it is possible to suppress contact of outside air to the contents within the container main body, so that the quality of the contents can be maintained favorably.

However, in the case of dispensing a low-viscosity content such as water, the dispensing container as described in Patent Document 1 has a wide angle shape when the dispensing container body is strongly squeezed. That is, there was a tendency for the liquid to be ejected from the ejection port in a spreading manner. From the viewpoint of preventing the contents from scattering when being discharged, it is desirable to discharge the contents in a single line as much as possible.

FIG. 1 is a longitudinal cross-sectional view showing the discharge container according to the first embodiment of the present invention in an upright state. 2 is a sectional view taken along line AA in FIG. 1. FIG. FIG. 2 is a top view of the hinge cap main body shown in FIG. 1; FIG. 2 is a longitudinal cross-sectional view showing the discharge container shown in FIG. 1 in a state at the time of discharging the contents. FIG. 7 is a longitudinal cross-sectional view showing a discharge container according to a second embodiment of the present invention.

Hereinafter, a discharge container according to an embodiment of the present invention will be illustrated in detail with reference to the drawings. In addition, in this specification, the vertical direction means the vertical direction when the discharge container is in an upright state. That is, the upper part is the upper part in FIG. 1, and the lower part is the lower part in FIG.

First, a discharge container 1A according to a first embodiment of the present invention will be illustrated in detail with reference to FIGS. 1 to 4. As shown in FIG. 1, a discharge container 1A according to the present embodiment includes a container body 2 and a hinge cap 3. The hinge cap 3 is attached to the mouth 2a of the container body 2, and closes the mouth 2a, and can discharge the contents contained in the container body 2 to the outside through the hinge cap 3.

The container body 2 has a bottle shape, and has a cylindrical mouth 2a, a body that is connected to the lower end of the mouth 2a and whose diameter is larger than the mouth 2a, and a bottom that closes the lower end of the body. . In this embodiment, a laminated peelable container (delami container), which is a type of double container, is used as the container body 1. The container main body 2, which is a laminated peelable container, has an outer layer body 4 and an inner layer body 5, and has a structure in which the inner layer body 5 is housed inside the outer layer body 4. The outer layer 4 constitutes the outer shell of the container body 2 and has a shape corresponding to the container body 2. The body of the outer layer 4 has flexibility and can be dented by being squeezed, and can be restored to its original shape from the dented state. The inner layer 5 is formed in a bag shape and is thinner than the outer layer 4, and is removably laminated on the inner surface of the outer layer 4. The opening of the inner layer body 5 is connected to the open end of the mouth portion 2a, and the inside of the inner layer body 5 serves as a storage space for contents. The inner layer body 5 can be peeled off from the inner surface of the outer layer body 4 and deformed to reduce its volume as the contents are discharged from the accommodation space.

An outside air inlet is provided at the bottom of the outer layer 4 to allow outside air to be introduced between the outer layer 4 and the inner layer 5. This outside air inlet can be constituted by a slit formed in a pinch-off portion at the bottom of the container body 2 formed by blow molding, for example. The outside air inlet is a space between the outer layer body 4 and the inner layer body 5 when the outer layer body 4 is restored to its original shape after squeezing the trunk of the outer layer body 4 and deforming the inner layer body 5 to reduce its volume. outside air can be introduced into the Note that the outside air inlet may be a hole in the outer layer 4, for example, as long as it can introduce outside air between the outer layer 4 and the inner layer 5 when the squeezed outer layer 4 is restored to its original shape. It can also be provided in other parts such as the mouth or the body, and its form is not limited to the slit, but can be in various shapes or configurations.

Such a container body 2, which is also called a delaminated container, is produced by, for example, coextruding a synthetic resin for the outer layer and a synthetic resin for the inner layer, which have low compatibility, to form a laminated parison, and then molding the laminated parison using a mold. It can be formed by blow molding. The double container used as the container body 2 is not limited to the above-mentioned laminated peelable container, but may also have a structure in which an inner layer body formed separately from the outer layer body is incorporated inside the outer layer body. Further, the container body 2 is not limited to a double container.

The content may be a liquid with low viscosity such as water, such as soy sauce. However, the viscosity of the contents is not particularly limited. Further, the contents may be a mixture of solids in a liquid. The type of contents is not particularly limited, and may be, for example, food seasonings, drinks, shampoos, conditioners, body soaps, cosmetics, or medicines.

The hinge cap 3 includes a valve body 6 and a hinge cap body 7. The valve body 6 is a spherical ball valve made of steel or synthetic resin, for example. However, the valve body 6 is not limited to a spherical shape. The hinge cap body 7 is configured as a single injection molded product made of, for example, synthetic resin, and includes a discharge cap body 8 and an overcap 10 connected to the discharge cap body 8 via a hinge 9. We are prepared. In this embodiment, a discharge cap 11 is constituted by a discharge cap main body 8 and a valve body 6. Note that the overcap 10 may be configured separately from the discharge cap main body 8.

The discharge cap main body 8 has a capped cylindrical shape, and includes a top wall 12 formed in a substantially disk shape, and a cylindrical mounting tube 13 that is integrally provided on the outer periphery of the top wall 12. The mounting tube 13 is attached to the mouth 2a such that it surrounds the outer periphery of the mouth 2a and the top wall 12 comes into contact with the open end of the mouth 2a. Note that, as shown in the figure, a seal cylinder 14 may be integrally provided on the lower surface of the top wall 12, which is formed to have a smaller diameter than the mounting cylinder 13 and comes into liquid-tight contact with the inner circumferential surface of the mouth portion 2a.

A fitting convex portion 15 is provided on the lower end side of the inner circumferential surface of the mounting tube 13, and this fitting convex portion 15 fits into a fitted convex portion 16 provided on the outer circumferential surface of the mouth portion 2a. As a result, the discharge cap main body 8 is attached to the mouth portion 2a in a state where it is prevented from coming off. That is, in this hinge cap 3, the discharge cap main body 8 is attached to the mouth portion 2a by plugging. The discharge cap main body 8 may be attached to the opening 2a by threading a female thread provided on the inner peripheral surface of the mounting tube 13 to a male thread provided on the outer peripheral surface of the opening 2a.

As shown in FIGS. 1 and 3, at a position slightly shifted from the center of the top wall 12 to the opposite side of the hinge 9, there is a discharge cylinder 18 having a cylindrical shape and having an upper end forming a discharge port 17. It is provided integrally with the top wall 12. The discharge cylinder 18 includes an outer cylinder part 18a that is integrally connected to the top wall 12 and curves outward while gradually expanding in diameter upward, and a three-stage cylinder that extends downward from the lower end of the outer cylinder part 18a. It has a shaped inner cylinder part 18b. In addition, instead of the outer cylinder part 18a, or in addition to the outer cylinder part 18a, an inner cylinder part 18b may be integrally connected to the top wall 12.

The overcap 10 is formed into a capped cylindrical shape having approximately the same diameter as the discharge cap main body 8, and can open and close the discharge cylinder 18 and the top wall 12 of the discharge cap 11 by rotating via the hinge 9. . The overcap 10 has a fitting convex portion 19 provided on the inner periphery of the opening edge thereof and a fitting convex portion 20 provided on the outer periphery of the top wall 12, so that the discharge cylinder of the discharge cap 11 can be connected to the overcap 10. 18 and the top wall 12 can be kept covered, that is, in a closed state. When the overcap 10 is closed, the discharge cylinder 18 is covered by the overcap 10, and the cylindrical stopper 21 integrally provided on the inner surface of the overcap 10 is inserted into the inner peripheral surface of the inner cylinder part 18b of the discharge cylinder 18. The flow path inside the discharge cylinder 18 is closed. On the other hand, a collar-shaped knob 22 that projects radially outward is integrally provided on the outer peripheral surface of the overcap 10 on the opposite side of the hinge 9. By pulling up this knob 22, the hinge can be opened. The overcap 10 can be rotated about 9 in a direction away from the discharge cylinder 18 to open the discharge cylinder 18. In this way, the discharge cylinder 18 can be opened and closed by the overcap 10.

As shown in FIGS. 1 to 3, the inner cylinder part 18b of the discharge cylinder 18 has a cylindrical upper wall 23 extending downward from the lower end of the outer cylinder part 18a, and a diameter decreasing downward from the lower end of the upper wall 23. a cylindrical inner wall 25 extending downward from the lower end of the upper inclined wall 24; a lower inclined wall 26 whose diameter decreases downward from the lower end of the inner wall 25; and a lower end of the lower inclined wall 26. It has a cylindrical lower wall 27 extending downward from. Note that the shapes of the upper wall 23, middle wall 25, and lower wall 27 are not limited to the cylindrical shape, and can be changed as appropriate according to the shape of the valve body 6, etc.

A lip portion 28 is provided on the radially inner side of the upper inclined wall 24. A valve holding portion 29 is provided on the radially inner side of the upper portion of the inner wall 25 . Further, a diaphragm portion 30 extending from the valve retaining portion 29 to the downwardly inclined wall 26 is provided on the inside of the inner wall 25 in the radial direction. A seating portion 31 is provided on the radially inner side of the downwardly inclined wall 26 . A baffle plate 32 is provided inside the lower wall 27 in the radial direction. In this way, the baffle plate 32 is arranged below the seating part 31, the valve holding part 29 is arranged above the seating part 31, and the lip part 28 is arranged above the valve holding part 29.

A baffle plate 32 is connected to the inner peripheral surface of the lower wall 27 via a connecting portion 33. The baffle plate 32 has a circular disk shape when viewed from above, and is swingable in the vertical direction around a connecting portion 33 disposed at one location on its outer periphery. The connecting portion 33 is preferably provided on the side of the hinge 9 when viewed from above, as shown in the figure. Here, "the connecting portion 33 is provided on the side of the hinge 9 when viewed from above" means that the connecting portion 33 is provided on the half-circumferential portion located on the hinge 9 side in the angular range over the entire circumference of the baffle plate 32 when viewed from the top. This means that the connecting portion 33 is provided such that the circumferential center of the connecting portion 33 is located. The outer peripheral surface of the baffle plate 32 has a conical shape whose diameter decreases upward. The lower end surface of the baffle plate 32 is arranged flush with the lower end surface of the lower wall 27. Note that the baffle plate 32 is not limited to a disk shape, and may be, for example, a rectangular plate shape. Further, the baffle plate 32 may be connected to the inner circumferential surface of the lower wall 27 at two or more locations on its outer circumference. The baffle plate 32 may be connected to the lower wall 27 in a non-swingable manner. The position of the lower end surface of the baffle plate 32 may be above or below the lower end surface of the lower wall 27.

The seating portion 31 is formed by the lower end of the inner circumferential surface of the downwardly inclined wall 26 . When the valve body 6 is seated on the seating portion 31, the flow of air through the inside of the discharge cylinder 18 is blocked or suppressed. Although not shown, the seating section 31 may be configured to form a holding gap between it and the valve body 6 seated on the seating section 31 to prevent air flow by holding the contents. good. That is, a notch portion large enough to be sealed with the contents may be provided in a portion of the seating portion 31. Depending on the type of contents, etc., there is a risk that the contents will harden and the valve body 6 will stick to the seating part 31, but by providing such a notch, the occurrence of sticking of the valve body 6 can be prevented. Or it can be suppressed. Note that the seating portion 31 may be formed without relying on the downwardly inclined wall 26. For example, an annular flange-shaped flange wall may be provided in place of the downwardly inclined wall 26, and the seating portion 31 may be formed by the upper surface of the flange wall.

In this embodiment, the throttle part 30 extends along the axial direction of the discharge cylinder 18 from the valve holding part 29 toward the seating part 31, and forms a main channel 34 on the opposite side of the hinge 9 when viewed from above. It has a letter shape. Here, "the main flow path 34 is formed on the opposite side of the hinge 9 when viewed from above" means that the main flow path 34 is formed in a half-circumferential portion located on the opposite side of the hinge 9 out of the angular range extending over the entire circumference of the discharge cylinder 18 when viewed from the top. , means that the main flow path 34 is formed such that the circumferential center of the main flow path 34 is located. Furthermore, the expression that the aperture part 30 is "C-shaped" means that the aperture part 30 is provided over an angular range exceeding half a circumference when viewed from above, that is, the main flow passage 34 is provided over a half circumference when viewed from above. This means that it is provided over an angular range of less than More specifically, the circumferential center of the main flow path 34 is located at the center of the half circumference located on the opposite side of the hinge 9 within the angular range over the entire circumference of the discharge cylinder 18 when viewed from above. . However, the circumferential position of the main flow path 34 can be changed as appropriate. Further, the aperture portion 30 is provided over approximately 240° when viewed from above. However, the angular range in which the aperture portion 30 is provided can be changed as appropriate. The main flow path 34 and the throttle section 30 have an arc shape when viewed from above. However, the shapes of the main flow path 34 and the constricted portion 30 are not limited to such a circular arc shape. The throttle portion 30 has an inner diameter that is larger than the outer diameter of the spherical valve body 6 and is constant from the lower end to the upper end. Although the inner diameter of the throttle portion 30 can be changed as appropriate, it is preferably set so that vertical movement of the valve body 6 can be smoothly guided. Alternatively, a configuration may be adopted in which the aperture section 30 is not provided.

The valve holding portion 29 can restrict upward movement of the valve body 6 by contacting only a part of the outer periphery of the valve body 6 when viewed from above. In this embodiment, the valve holding portion 29 is constituted by three claws 35 arranged at equal intervals in the circumferential direction. Each pawl 35 projects diagonally upward from the upper end of the constriction portion 30 toward the radially inner side of the discharge cylinder 18 . However, the number, arrangement, and shape of the claws 35 constituting the valve holding portion 29 can be changed as appropriate. However, it is preferable that the claw 35 is not provided at a position overlapping the main flow path 34 when viewed from above. The valve holding portion 29 is not limited to the claw 35.

In this embodiment, the lip portion 28 has a C-shape that projects obliquely upward from the inner circumferential surface of the upper inclined wall 24 and forms a cutout portion 36 on the opposite side of the hinge 9 when viewed from above. Here, "forming the notch 36 on the side opposite to the hinge 9 when viewed from above" refers to a half-circumferential portion located on the opposite side from the hinge 9 within the angular range over the entire circumference of the discharge cylinder 18 when viewed from the top. This means that the notch portion 36 is formed such that the circumferential center of the notch portion 36 is located at the . Furthermore, the expression that the lip portion 28 is “C-shaped” means that the lip portion 28 is provided over an angular range exceeding half the circumference when viewed from above, that is, the notch portion 36 is provided over an angular range of more than half the circumference when viewed from above. This means that it is provided over an angular range of less than half the circumference. More specifically, the circumferential center of the notch 36 is located at the center of the half circumference located on the opposite side of the hinge 9 within the angular range over the entire circumference of the discharge cylinder 18 when viewed from above. There is. However, the circumferential position of the notch 36 can be changed as appropriate. Further, the lip portion 28 is provided over approximately 240° when viewed from above. However, the angular range in which the lip portion 28 is provided can be changed as appropriate. The notch portion 36 and the lip portion 28 have an arcuate shape when viewed from above. However, the shapes of the notch portion 36 and the lip portion 28 are not limited to such a circular arc shape. The lip portion 28 has an inner diameter larger than the inner diameter of the constriction portion 30. The inner diameter of the lip portion 28 may be the same as the inner diameter of the constricted portion 30 or may be smaller than the inner diameter of the constricted portion 30. The lip portion 28 may be provided on the inner circumferential surface of the upper wall 23 or the middle wall 25 instead of being provided on the inner circumferential surface of the upper inclined wall 24. Moreover, the upper wall 23 and the middle wall 25 may be configured to have the same diameter without providing the upper inclined wall 24. Alternatively, a configuration may be adopted in which the lip portion 28 is not provided.

According to the discharge container 1A according to this embodiment, the contents can be discharged as shown in FIG. The procedure for discharging the contents is, for example, as follows. First, the user opens the overcap 10, tilts the discharge container 1A so that the overcap 10 is on top, and squeezes the body of the container body 2. Then, due to the increase in the internal pressure of the container body 2, the weight of the contents, and the weight of the valve body 6, the valve body 6 separates from the seating portion 31 and descends, and comes into contact with the valve retainer 29 and stops. Moreover, at this time, due to the increase in the internal pressure of the container body 2 and the weight of the contents, the baffle plate 32 swings and the cross-sectional area of the flow path inside the lower wall 27 increases, and the inside of the accommodation space of the container body 2 is increased. The contents flow into the inside of the lower wall 27 from below. At this time, since the cross-sectional area of the flow path inside the lower wall 27 is reduced by the amount that the baffle plate 32 is provided, the flow path resistance increases accordingly, and low viscosity materials such as water are mixed with the contents. Even in this case, the force of the discharged contents can be suppressed. Therefore, the contents are prevented from being discharged in a wide-angle shape, and the contents can be discharged in a rectified state. Moreover, for this reason, it is possible to prevent the contents from scattering when discharging the contents. Furthermore, in this embodiment, the baffle plate 32 swings as the body is squeezed, increasing the cross-sectional area of the flow path, so that the contents are not discharged all at once at the beginning of the squeeze. , it is easy to adjust the discharge amount of the contents. The contents that have flowed into the inside of the lower wall 27 mainly flow linearly through the main channel 34 and the notch 36, and are discharged from the discharge port 17. Therefore, also from this point of view, the content is prevented from being discharged in a wide-angle shape. Furthermore, in this embodiment, the connecting portion 33 that swingably supports the baffle plate 32 is provided on the side of the hinge 9 when viewed from above, and the main flow path 34 and the notch portion 36 are located opposite to the hinge 9 when viewed from above. Since it is provided on the side, the contents can flow in a straight line from the lower wall 27 to the discharge port 17. Furthermore, the contents that have flowed into the inside of the lower wall 27 also flow into a small gap between the constriction part 30 and the valve body 6, but the flow that has passed through the gap (indicated by a relatively thin white arrow in FIG. 4) is bent by the lip portion 28 and joins the main flow (indicated by a relatively thick white arrow in FIG. 4) that has passed through the main flow channel 34 and the cutout portion 36. Therefore, also from this point of view, the content is prevented from being discharged in a wide-angle shape.

Next, with reference to FIG. 5, a discharge container 1B according to a second embodiment of the present invention will be illustrated in detail. As shown in FIG. 5, the discharge container 1B according to the present embodiment is different from the first embodiment in the configuration of the throttle part 30', the valve presser part 29', and the lip part 28', and in other respects. The configuration is the same as that of the first embodiment.

In this embodiment, the aperture part 30' does not "form the main flow path 34 on the opposite side of the hinge 9 in top view" and does not have a "C-shape" as compared to the first embodiment. The case is different. The constricted portion 30' is composed of three ribs 37 arranged at equal intervals in the circumferential direction. A claw 35' is provided at the upper end of each rib 37. These three claws 35' constitute a valve holding portion 29'. The lip portion 28' differs from the first embodiment in that it does not "form a notch 36 on the opposite side of the hinge 9 when viewed from above" and does not have a "C-shape". There is. The lip portion 28' is provided around the entire circumference of the discharge tube 18'.

The discharge container 1B according to this embodiment has a baffle plate 32 as in the first embodiment. Therefore, according to the discharge container 1B according to the present embodiment, the force of the contents to be discharged is suppressed to prevent the contents from scattering when the contents are discharged, and also to suppress the contents from being discharged in a wide-angle shape. can do.

The foregoing description merely illustrates one embodiment of the invention and is not intended to limit the scope of the claims. The embodiments described above can be modified in various ways based on the basic matters of the present disclosure.
