Description

The present invention relates to a discharge device that is provided at the mouth of various container bodies, such as tube-shaped containers, and discharges the contents of the container body to the outside.

For example, pouch containers and tube containers (for example, see Patent Document 1) have been used as containers for containing fluid contents such as toothpaste, cosmetics, and pharmaceuticals in the form of liquids, pastes, and gels. There is. The tube container is constituted by a laminate or the like having a light shielding layer between an innermost layer and an outermost layer formed of a resin material such as polyethylene (see, for example, Patent Document 2). Generally, tube containers have flexibility and are configured such that when the body of the tube container is pressed, the contents within the body are discharged from the mouth. Tube containers can be used on a daily basis and for relatively long periods of time, such as from several days to several months, because the contents can be easily discharged and the deterioration of the contents can be suppressed with a light-shielding layer, etc. It is widely used as a storage container for products, etc.

In recent years, the environmental impact of microplastics has become a worldwide concern. Therefore, it is required to reduce the amount of resin in packaging containers, and in tube containers and the like, it is required to reduce the amount of resin constituting the laminate and make the tube containers thinner.

By the way, when the remaining amount of the contents in the tube container becomes low, when the body is pressed, the contents will move inside the tube container by escaping from the part that is crushed by the pressure, so the contents will not be able to be taken into the mouth. It becomes difficult to gather people in a club. For this reason, when the remaining amount of the contents becomes low, it is common practice to roll up the rear end of the tube container to move the contents to the mouth. However, as tube containers become thinner, their rigidity and the like become insufficient, making it difficult to hold the rear end of the tube container in a rolled up shape. Therefore, when the remaining amount of the contents becomes small, it becomes difficult to collect the contents around the mouth, and the contents may not be used up to the end. When the contents are expensive cosmetics, etc., some consumers try to cut the tube container and use the contents to the last. However, if contents equivalent to the amount used multiple times remain in the tube container, when the tube container is cut, the contents may be exposed to light, oxygen, etc. and deteriorated. Therefore, in this case as well, it becomes difficult to use the contents to the end.

On the other hand, Patent Document 3 proposes a pouring tool for pouring out the contents of a tube container to the end. The dispensing tool has two rods that form a long hole into which the rear end of the tube container can be inserted, and by moving the tube container toward the mouth side while sandwiching the tube container with these two rods, the contents can be dispensed. is held around the mouth. However, with such a dispensing tool, it is necessary to move the dispensing tool toward the mouth side while firmly pinching the tube container, so if the tube container becomes thin, there is a risk that the tube container will be damaged. Further, since it is necessary to move the pouring tool toward the mouth depending on the amount of content remaining in the tube container, there is also the problem that this operation is time-consuming.

The cap portion is configured to be removably attached to the outer circumferential surface of the mouth portion, and the cap portion has an abutment piece that abuts the inner circumferential surface of the peripheral wall of the mouth portion, and the pressure contact body includes: The contact piece was pressed against the contact piece .

In the discharge device, the discharge passage of the discharge part is opened and closed, and when the discharge passage is opened, the content is allowed to move only in the direction from the discharge part to the outside, and the gas is transferred to the cylindrical part. It is preferable to include a second check valve that prevents the inflow of.

Furthermore, in the discharge device, when the remaining amount of the content is equal to or more than the predetermined amount, after the content is discharged from the discharge part, the content remains in the internal space until the content reaches the predetermined amount. Preferably, it is filled.

It is preferable that the container main body has the flexible body, and the elastic restoring force of the cylindrical part is larger than the elastic restoring force of the body.

It is preferable that the container body provided with the discharger is a tube container or a pouch container.

The discharge device according to the present invention includes a flexible cylindrical portion having an internal space that communicates with the mouth of the container body, and includes a discharge portion that discharges the contents stored in the internal space to the outside. Therefore, when discharging the contents stored in the container body to the outside, the contents pass through the internal space of the cylindrical part. A check valve is provided in the communication path between the mouth and the cylindrical part, which allows the contents to move in the direction from the container body to the cylindrical part, but prevents the contents from moving in the opposite direction. Prevented. Therefore, even when the remaining amount of contents is low, by moving the contents inside the container body toward the cylindrical part, the check valve can prevent the contents from returning to the container body again. can. Since a predetermined amount of contents can be accommodated in the internal space of the cylindrical portion, depending on the remaining amount of the contents, the entire amount of the remaining contents can be accommodated within the cylindrical portion. Since the cylindrical part is flexible, pressing the cylindrical part by hand will reduce the amount of remaining content compared to pressing the container body when it does not have the dispensing device. Even when the amount is low, it becomes easy to discharge the contents to the outside.

FIG. 1 is a partially sectional view showing an example of a discharge device and a container according to the present invention. FIG. 2 is an enlarged cross-sectional view of the ejector of FIG. 1; FIG. 2 is a diagram for explaining how the ejector and container of FIG. 1 are used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a dispensing device and a container according to the present invention will be described below with reference to the drawings. The container 100 shown in FIG. 1 is composed of a container body 10 and a discharge device 20 provided at the mouth portion 11 of the container body 10, and an overcap 30 is provided on the discharge portion 21 of the discharge device 20. . Here, the container body 10, the discharge device 20, and the overcap 30 are arranged so that their central axes are located on a common axis O. Furthermore, in the present embodiment, in the direction along the common axis O, the side where the overcap 30 is provided is the upper side, and the side where the container body 10 is provided is the lower side.

The container main body 10 shown in FIG. 1 is a main body portion of a so-called tube container, and includes a flat cylindrical body 12 that is flexible and has a storage space (first storage portion) 12a for storing contents therein. , and the above-mentioned mouth portion 11 which is continuously provided above the body portion 12. Further, a seal portion 13 is provided below the body portion 12 and is formed by flattening and heat welding.

The contents accommodated in the accommodation space 12a of the body 12 include, for example, cosmetics, medicines, foods, etc., as well as adhesives, caulking agents, etc., and fluid objects such as liquids, pastes, and gels. is accommodated.

The body portion 12 can be constructed from a laminate including a resin layer/light shielding layer/resin layer, for example. By interposing the light shielding layer between the resin layers, the contents can be prevented from being photodegraded. The innermost layer that comes into contact with the contents and the outermost layer that comes into contact with the outside air can be layers made of various container packaging resins, such as polyethylene (LDPE, LLDPE, HDPE) and polyethylene terephthalate (PET). . Further, the light-shielding layer may be, for example, an aluminum layer or a resin layer coated with a light-shielding paint on one surface. Further, an adhesive layer such as an anchor coat layer or a dry laminate layer may be provided between each layer to improve the adhesiveness between each layer. However, the light shielding layer is not an essential component. Moreover, it is preferable that the constituent material of the body part 12 be an appropriate material depending on the contents.

The mouth portion 11 includes a substantially cylindrical peripheral wall 11a and an annular flat bottom portion 11c in which a communication hole 11b is formed substantially in the center. A male thread is provided on the outer peripheral surface of the peripheral wall 11a. When the body part 12 is pressed, the contents in the storage space 12a are discharged from the mouth part 11 and transferred to the discharger 20 side.

The discharge device 20 includes the discharge section 21 and a cylindrical section 22 having an internal space 22a that communicates with the mouth section 11 of the container body 10 and the discharge section 21. A cap portion 23 that is attached to the mouth portion 11 of the container body 10 is provided below the cylindrical portion 22 . Further, a first check valve 24 (check valve) is provided in the communication path between the cylindrical portion 22 and the mouth portion 11 of the container body 10, and a second check valve 25 is provided in the discharge portion 21. There is. Further, the overcap 30 is attached to the discharge portion 21 .

Hereinafter, the configuration of the ejector 20 will be explained in more detail with reference to FIG. 2. First, the cylindrical portion 22 will be explained. The cylindrical portion 22 is flexible, and in this embodiment is formed into a substantially cylindrical shape that is elongated in the direction of the common axis O.

Although the internal space (second storage part) 22a of the cylindrical part 22 has a smaller volume than the storage space 12a of the container body 10, it has a volume that can hold a predetermined amount of contents. The amount (predetermined amount) of the contents that can be held in the internal space 22a is not particularly limited, but for example, it may be an amount equivalent to the usage amount of 0.5 to 15 times of the contents. Preferably, the amount corresponds to a usage amount of 1 to 10 times, more preferably an amount equivalent to a usage amount of 2 to 5 times, etc., and the internal space 22a of the cylindrical portion 22. The volume of can be adjusted to an appropriate size.

The cylindrical portion 22 is preferably made of an elastic material that can be restored to its original shape when it is elastically deformed. For example, it can be constructed from a laminate made of the same material as the body 12. Note that the elastic restoring force when the cylindrical portion 22 is restored is preferably set to be larger than the elastic restoring force when the trunk 12 is restored. By setting the elastic restoring force in this manner, as will be described later, when the pressed cylindrical portion 22 returns to its original state, the contents of the body portion 12 can be more reliably sucked up into the cylindrical portion 22. The elastic restoring force of the body part 12 and the cylindrical part 22 can be adjusted, for example, by the shapes and materials of the body part 12 and the cylindrical part 22, as well as their thicknesses. For example, when the body part 12 is made thinner than the cylindrical part 22, in addition to being able to set the elastic restoring force as described above, it is possible to make the body part 12 thinner than a conventional tube container. , the amount of resin in the container body 10 can be reduced. In addition, by making the cylindrical part 22 as thick as the conventional one, it becomes easy to discharge the contents even when the remaining amount is low, and the dispensing device 20 can be repeatedly used for a long period of time. It can provide usable durability.

The cap part 23 includes a contact piece 23a that comes into contact with the inner peripheral surface of the peripheral wall 11a of the mouth part 11 of the container body 10, and a female thread 23b that is screwed into a male thread formed on the outer peripheral surface of the mouth part 11. It is provided with a peripheral wall 23c formed on the inner circumferential surface, and an annular flat plate-shaped ceiling wall 23d that covers the abutment piece 23a and the upper end of the peripheral wall 23c. The top wall 23d is connected to the outer circumferential surface of the cylindrical portion 22 so as to protrude outward from the outer circumferential surface of the cylindrical portion 22. The length of the contact piece 23a in the direction along the common axis O is shorter than the length of the peripheral wall 11a of the mouth 11 of the container body 10, and the contact piece 23a is in contact only above the peripheral wall 11a.

The first check valve 24 opens and closes a communication path between the mouth portion 11 of the container body 10 and the cylindrical portion 22 of the discharge device 20, and when the communication path is opened, the first check valve 24 moves from the container body 10 to the cylindrical portion 22. Allows movement of contents only in the direction. When the communication path is closed by the first check valve 24, the movement of the contents in the direction from the cylindrical portion 22 toward the container body 10 is blocked, and the inflow of air is also blocked.

In this embodiment, the first check valve 24 is connected to the pressure contact body 24a via a pressure contact body 24a that is pressed against the contact piece 23a of the cap portion 23, and one or more connection pieces 24b. A valve body 24c is provided. The pressing body 24a, the connecting piece 24b, and the valve body 24c are all made of an elastic material.

The press member 24a is formed into a cylindrical shape having an outer diameter larger than the inner diameter of the abutting piece 23a of the cap portion 23. The length of the pressing member 24a in the direction along the common axis O is approximately equal to the length of the peripheral wall 11a of the mouth portion 11 of the container body 10. Approximately the upper half of the pressing member 24a is pressed against the inside of the abutting piece 23a of the cap portion 23, so that the first check valve 24 is immovably fixed inside the cap portion 23. In addition, the thickness of approximately the lower half of the pressure contact body 24a becomes thinner toward the bottom, and a space is provided between the inner circumferential surface of the peripheral wall 11a of the mouth portion 11 of the container body 10 and the lower part of the pressure contact body 24a. ing.

The valve body 24c has a circular shape with an outer diameter larger than the diameter of the communication hole 11b of the mouth portion 11 of the container body 10, and the communication hole 11b is closed from above by the valve body 24c. The outer edge of the valve body 24c is brought into contact with the upper surface of the bottom 11c of the mouth 11 of the container body 10.

The connecting piece 24b is a part for connecting the valve body 24c to the lower end of the pressure contact body 24a, and is formed in, for example, a short rectangular shape. When a force is applied to the valve body 24c in the direction from the housing space 12a of the container body 10 toward the internal space 22a of the cylindrical portion 22, the connecting piece 24b is elastically deformed, and the valve body 24c deforms the connecting piece 24b. Rotate upwards on a fulcrum. As a result, a communication path between the accommodation space 12a of the container body 10 and the internal space 22a of the cylindrical portion 22 is opened. When the force applied to the valve body 24c in the direction from the housing space 12a of the container body 10 toward the internal space 22a of the cylindrical portion 22 is released, the valve body 24c returns to its original position due to the elastic restoring force of the connecting piece 24b. Returning, the communication hole 11b is closed and the communication path is closed.

Next, the discharge section 21 will be explained. The discharge part 21 has a nozzle shape, has a discharge passage 21a elongated in the direction along the common axis O, and has a male thread 21b on its outer peripheral surface. A second check valve 25 is provided at the lower end of the discharge passage 21a, and the upper end of the discharge passage 21a serves as a discharge port 21c through which the contents are discharged to the outside.

The second check valve 25 opens and closes the discharge passage 21a, and when the discharge passage 21a is opened, allows the contents to move only in the direction from the discharge part 21 to the outside. Prevent gas inflow.

In the present embodiment, the second check valve 25 includes a spherical valve 25a that closes the lower end of the discharge passage 21a, that is, the entrance from the cylindrical portion 22 to the discharge passage 21a. It is supported by a support portion 25b having a V-shaped cross section provided at the entrance of the tube, and movement toward the cylindrical portion 22 is restricted. A small hole 25c communicating with the discharge path 21a is provided at the lower part of the support portion 25b. Further, above the support portion 25b, a regulating piece 25d is provided that allows upward movement of the spherical valve 25a within a predetermined range. The regulating piece 25d allows the spherical valve 25a to move upward within a predetermined range.

When a force is applied to the second check valve 25 in the direction from the cylindrical portion 22 toward the discharge path 21a, the spherical valve 25a that has closed the small hole 25c moves upward within the range restricted by the restriction piece 25d. Move to. As a result, the discharge passage 21a opens. When the force is released from the second check valve 25 in the direction from the cylindrical part 22 toward the discharge passage 21a, the spherical valve 25a moves downward, closes the small hole 25c, and closes the discharge passage 21a. . Note that when the attitude of the container 100 is changed, the spherical valve 25a moves between the support portion 25b and the regulating piece 25d due to the force associated with its own weight, and opens and closes the discharge passage 21a.

By adjusting the diameter of the discharge passage 21a and the diameter of the small hole 25c provided in the lower part of the support portion 25b, the discharge amount of the contents can be adjusted.

Next, the operation of the discharger 20 and container 100 configured in this way will be explained.

When the user holds the container 100 diagonally with the discharger 20 side facing downward and presses the body 12 of the container body 10, the internal pressure in the accommodation space 12a of the body 12 increases, causing the valve of the first check valve 24 to rise. A force is applied to the body 24c in a direction away from the bottom portion 11c. As a result, the connecting piece 24b is elastically deformed, the valve body 24c is rotated about the connecting piece 24b, and the communication passage is opened. When the communication path is opened, the contents move from the accommodation space 12a of the container body 10 to the internal space 22a of the cylindrical portion 22. Since the spherical valve 25a separates from the support part 25b due to the force due to its own weight or the force received from the contents moved to the internal space 22a, the discharge passage 21a opens and the contents are discharged from the discharge port 21c of the discharge part 21 to the outside. Exhale.

When the user stops pressing the body 12 and changes the posture of the container 100 so that the discharger 20 side faces upward as before, the first check valve 24 and the second check valve 25 open the communication path and The discharge passage 21a is closed. At this time, since the movement of the contents and air to the body 12 of the container body 10 is blocked by the first check valve 24, the body 12 is deflated and deformed by the amount by which the contents are discharged. On the other hand, since the internal space 22a of the cylindrical part 22 serves as a flow path when the contents are discharged from the discharge part 21, the internal space 22a is filled with the contents.

If some content remains in the container 100, it is possible to discharge the content as described above. By the way, when the remaining amount of the contents is getting low, even if you press the body with a conventional tube container, the contents will move inside the tube container by escaping from the part that is crushed by pressure, so the contents will be It is difficult to collect the liquid in the mouth and discharge it to the end. However, in the container 100, as described above, the internal space 22a of the cylindrical portion 22 is filled with a predetermined amount of content each time the content is discharged. Therefore, even if the remaining amount of the contents is low, as shown in FIG. The stop valve 25 opens, and the liquid inside the cylindrical part 22 is discharged from the discharge part 21.

When the contents are discharged in this manner, the cylindrical portion 22 is deflated and deformed. At this time, the second check valve 25 blocks air from flowing from the discharge portion 21 into the internal space 22a of the cylindrical portion 22. Further, the first check valve 24 blocks the contents and air from flowing from the cylindrical portion 22 into the body portion 12 . Therefore, when the cylindrical part 22 attempts to return to its original shape due to the elastic restoring force of the cylindrical part 22, an internal pressure difference occurs between the internal space 22a of the cylindrical part 22 and the housing space 12a of the body part 12, The first check valve 24 opens. As a result, the ejector 20 functions like a dropper and sucks up the contents in the storage space 12a of the body 12. Therefore, after the contents are discharged, the internal space 22a of the cylindrical portion 22 is filled with the contents until a predetermined amount is reached. As described above, if the elastic restoring force of the cylindrical part 22 is set to be larger than the elastic restoring force of the body part 12, the contents can be sucked up into the internal space 22a more reliably.
At this time, if the amount of content remaining in the storage space 12a of the body 12 is small and the content cannot be sucked up into the cylindrical part 22 properly, the content may be sucked up from the outside of the body 12 by hand or the like into the cylindrical part 22. It is preferable to push it up so as to collect it on the side of 22, thereby promoting the suction of the contents.

When the remaining amount of the contents in the container 100 becomes smaller than the volume of the internal space 22a of the cylindrical portion 22, almost all of the contents in the body 12 have been sucked up into the cylindrical portion 22. By pressing the shaped portion 22, almost all of the contents in the container 100 can be discharged from the discharge portion 21 to the outside.

The discharge device 20 of the embodiment described above is provided at the mouth part 11 of the container body 10, and has an internal space 22a communicating with the mouth part 11 and the discharge part 21 for discharging the contents to the outside. A flexible cylindrical portion 22 is provided. Therefore, when discharging the contents stored in the container body 10 to the outside, the contents pass through the internal space 22a of the cylindrical portion 22. The first check valve 24 provided in the communication path between the mouth portion 11 and the cylindrical portion 22 allows the contents to move in the direction from the container body 10 toward the cylindrical portion 22, but vice versa. Movement of the contents in the direction is prevented. Therefore, even when the remaining amount of contents is low, if the contents in the container body 10 are moved to the side of the cylindrical part 22, the first check valve prevents the contents from returning to the container body 10 again. 24 can prevent this. Since a predetermined amount of contents can be held in the internal space 22a of the cylindrical part 22, the entire amount of the remaining contents can be accommodated in the cylindrical part 22 depending on the remaining amount of the contents. Since the cylindrical part 22 has flexibility, by pressing the cylindrical part 22, the contents in the cylindrical part 22 can be easily discharged from the discharge part 21 to the outside as described above.

Further, the discharge device 20 includes a second check valve 25 in the discharge passage 21a, which allows the contents to move from the discharge part 21 to the outside, while allowing air etc. to flow into the cylindrical part 22 from the discharge part 21. is prevented from doing so. Therefore, oxidation, deterioration, hardening, etc. of the contents can be suppressed. In particular, when the contents contain easily oxidizable substances such as vitamin C, or when the contents harden when exposed to air, such as adhesives or caulking agents, the second check valve 25 is installed in the discharge part 21. By providing this, the quality of the contents can be easily maintained. Note that even when the second check valve 25 is not provided, the first check valve 24 prevents the contents and air from flowing into the container body 10, so the quality of the contents inside the container body 10 is maintained. can do.

Furthermore, by providing the second check valve 25 in the discharge part 21, as described above, each time the contents are discharged from the discharge part 21, the cylindrical part 22 functions like a dropper, and the contents inside the container body 10 are The substance is sucked up into the internal space 22a of the cylindrical part 22, and the internal space 22a is filled with the contents until the predetermined amount is reached. A first check valve 24 and a second check valve 25 prevent air from entering the accommodation space 12a of the container body 10. When the container body 10 is a tube container or a pouch container, each time the contents are discharged, the tube container or pouch container deflates by the amount of the contents discharged. Therefore, there is no need to perform operations such as rolling up the tube container or pouch container from the rear end when the remaining amount of the contents is low, unlike in the conventional case.

Furthermore, since the ejector 20 is detachably provided at the mouth 11 of the container body 10, the ejector 20 can be attached to another container main body 10 and used. For example, by forming the ejector 20 from a durable resin material that can be used repeatedly as described above, the container body 10 can be made thinner and the amount of waste plastic can be reduced. Further, by enabling the dispensing device 20 itself to be repeatedly used for a long period of time, it is possible to reduce the amount of waste plastic related to the dispensing device 20.

The ejector 20 of the embodiment described above is only one aspect of the present invention, and the ejector according to the present invention is not limited to the above aspect, and can be modified as appropriate without departing from the spirit of the present invention. Of course it is. For example, in the above embodiment, the discharge device 20 is configured to include the cap portion 23 provided with the female thread 23b, and by screwing this into the male screw provided in the mouth portion 11 of the container body 10, the container body 10 is Although the discharge device 20 is detachably provided to the container body, and the discharge device 20 can be attached to another container body (10), the container body (10) and the discharge device (20) are configured integrally. Good too. However, as described in the above embodiment, by providing the dispensing device 20 in a detachable manner with respect to the container body 10, the dispensing device 20 can be used repeatedly, which is preferable from the viewpoint of reducing the amount of waste plastic. Of course, the discharge device (20) may be detachably attached to the container body (10) by a method other than the male thread and the female thread 23b. For example, the opening (11) of the container body (10) is provided with an annular convex portion that protrudes in the circumferential direction, and the dispensing device (20) is provided with an external fitting portion having a groove that is externally fitted into the convex portion, The dispensing device (20) may be made detachable from the opening (11) of the container body (10) by elastically deforming the external fitting portion of the dispensing device (20). However, by employing the male screw and the female screw 23b, it becomes easy to attach the ejector 20 to another container body (10).

Furthermore, the specific configurations of the first check valve 24 and the second check valve 25 are not limited to the embodiments described above. Furthermore, although the discharge device 20 of the above embodiment is equipped with both the first check valve 24 and the second check valve 25, for example, instead of the second check valve 25, the discharge port 21c is made airtight. A closure plug or the like may be provided. When in use, the opening plug is removed from the outlet 21c to discharge the contents, and then the opening 21c is closed with the opening plug in a state where the cylindrical portion 22 is crushed. The contents in the internal space 22a of the container body 10 can be sucked up into the cylindrical portion 22 by the restoring elastic force. However, from the viewpoint of suppressing air from flowing into the inside of the discharge part 21, it is preferable to provide the discharge part 21 with a check valve (second check valve 25) as described above.

Furthermore, if the volume of the internal space 22a of the cylindrical portion 22 is set to a volume corresponding to the amount of content used for one use, pressing the cylindrical portion 22 will always discharge the amount of content for one use. It can be discharged from the section 21. Therefore, the dispensing device 20 can also be used as a cap that can easily measure the amount for one use.

Further, in the above embodiments, a tube container is taken as an example of the container body 10, but the discharger according to the present invention is not limited to tube containers, but can be applied to other containers such as pouch containers. Further, it is preferable to apply the present invention to a container whose purpose is to easily discharge a required amount of contents while avoiding contact between the contents and air.
