Description

Content ejector and container

[0001] The present invention relates to a content ejector and a container.

[0002] It is known to take out the cosmetics contained in a container using a spatula or other extracting tool. By taking out the cosmetics using a spatula or other extracting tool, it can be used hygienically and it becomes easier to use up all the cosmetics contained in the container.

[0003] Patent Document 1 discloses a configuration for taking out the contents using a spatula.

[0004] Japanese Unexamined Patent Application Publication No. 2024-94541

[0005] However, in order to take out the cosmetics contained in a container using a spatula or other extracting tool, it is necessary to have the extracting tool separately from the container in which the contents such as cosmetics are contained. Also, when holding the extracting tool in the container, it is necessary to provide the container with a structure and space for holding the extracting tool, and the container may become larger.

[0006] An object of the present invention is to provide a content ejector and a container that can be used hygienically without using an extracting tool.

[0007] To achieve the above object, the content ejector of the present invention is a content ejector disposed in a bottomed cylindrical container body for discharging the contents contained in the container body to the outside of the container body, and includes a cylindrical member disposed in the container body along the inner surface of the container body, and a pushing member provided movably along the inner surface of the cylindrical member within the cylindrical member. The cylindrical member has a communication portion extending in the axial direction of the cylindrical member between an outer wall portion along the inner surface of the container body and an inner wall portion along which the pushing member moves when the pushing member moves. The inner wall portion has a communication structure at the bottom-side end portion of the container body for communicating the region inside the inner wall portion and the communication portion between the end portion and the bottom of the container body. The communication portion has a discharge port for discharging the contents contained in the container body at the end portion on the opposite side of the communication structure.

[0008] In the present invention configured as described above, when the pushing member is moved along the inner surface of the cylindrical member, the contents contained in the container body enter the connecting section via the connecting structure and are discharged from the discharge port. In this way, by configuring the container so that the contents contained in the container body are discharged from the discharge port simply by moving the pushing member along the inner surface of the cylindrical member, it becomes possible to use the container hygienically without using a separate removal tool.

[0009] Furthermore, the pressing member may be provided so as to be movable within the cylindrical member along the inner surface of the cylindrical member while ensuring a predetermined level of airtightness between it and the inner surface of the cylindrical member.

[0010] In this configuration, the pressing member can move within the cylindrical member while ensuring airtightness between the pressing member and the inner surface of the cylindrical member.

[0011] Furthermore, the pressing member may be configured to have an elastic portion in the part facing the inner surface of the cylindrical member, for ensuring a predetermined level of airtightness between it and the inner surface of the cylindrical member.

[0012] In this configuration, the elastic force of the elastic part can be used to ensure airtightness between the pressing member and the inner surface of the cylindrical member.

[0013] Furthermore, the cylindrical member may be configured to have a holding surface around the discharge port for holding the contents discharged from the discharge port.

[0014] In this configuration, the contents discharged from the discharge port can be temporarily held by the holding surface.

[0015] Alternatively, the holding surface may be configured to be inclined toward the bottom of the container body from the periphery of the cylindrical member toward the center of the axis of the cylindrical member.

[0016] In this configuration, it becomes easier to wipe away the contents held on the retaining surface.

[0017] Furthermore, the pressing member may have a mountain-shaped bottom that protrudes on the side opposite to the bottom of the container body.

[0018] In this configuration, even if you have long fingernails, it becomes easier to push in the push-in component with your fingers.

[0019] Furthermore, the container in which the material dispensing device is housed within the container body may have the same mountain-like shape as the bottom of the pushing member.

[0020] In this configuration, the bottom of the push-in member is shaped like a mountain, yet the contents stored inside the container can be used up completely.

[0021] According to the present invention, the product can be used hygienically without the need for a dispensing tool.

[0023] Embodiments of the present invention will be described below with reference to the drawings. In the following description, "axial direction" refers to the direction in which the axes of the cylindrical container body 10, the cylindrical member 20, and the pressing member 30 are oriented.

[0024] <Overall Configuration> Figure 1 is an external perspective view showing one embodiment of a container having a contents dispensing device according to the present invention.

[0025] As shown in Figure 1, this embodiment is a container 1 in which a container body 10 is fitted with a container dispensing device 2. The container dispensing device 2 has a cylindrical member 20 and a pushing member 30, and is fitted so that the pushing member 30 is housed inside the cylindrical member 20. The container dispensing device 2 is fitted so that it is housed inside the container body 10.

[0026] The following describes each component.

[0027] <Container body 10> Figure 2 is a view of the container body 10 shown in Figure 1, viewed from diagonally above.

[0028] As shown in Figure 2, the container body 10 in Figure 1 has a bottomed cylindrical shape in which one end of the cylindrical side portion 12 is closed by the bottom portion 11.

[0029] The bottom portion 11 is circular to match the cylindrical side portion 12, and has a mountain-like shape with the central part convex upward to match the shape of the bottom portion 31 (see Figure 6) of the push-in member 30, which will be described later. This mountain-like shape is identical to that of the bottom portion 31 of the push-in member 30.

[0030] The side portion 12 has a tapered shape, with the outer and inner diameters of both cylindrical ends being slightly smaller at the end facing the bottom portion 11. A flange portion 13 is provided at the end of the side portion 12 opposite to the bottom portion 11 in the axial direction. The flange portion 13 is a donut-shaped plate that extends around the entire circumference of the side portion 12 and widens outward from the end opposite to the bottom portion 11. As a result, the outer diameter of the flange portion 13 is larger than the outer diameter of the end of the side portion 12 opposite to the bottom portion 11.

[0031] <Cylindrical Member 20> Figure 3 is a view of the cylindrical member 20 shown in Figure 1 from diagonally above. Figure 4 is a view of the cylindrical member 20 shown in Figure 1 from diagonally below. Figure 5 is a view of the cylindrical member 20 shown in Figure 1 from below.

[0032] As shown in Figures 3 to 5, the cylindrical member 20 in Figure 1 has a side portion 21 and a holding portion 26.

[0033] The side portion 21 has an outer wall portion 21a and an inner wall portion 21b. Both the outer wall portion 21a and the inner wall portion 21b are cylindrical with open ends. The outer wall portion 21a and the inner wall portion 21b have the same axial length, but the outer wall portion 21a has a larger diameter than the inner wall portion 21b. The inner wall portion 21b is positioned inside the outer wall portion 21a with their centers offset from each other, creating a space in part between the outer wall portion 21a and the inner wall portion 21b, while the other parts are integrated. A communication portion 23 is provided in the space created between the outer wall portion 21a and the inner wall portion 21b.

[0034] A communication opening 24 is provided at one end of the inner wall portion 21b in a region facing the communication portion 23. The communication opening 24 is an example of a communication structure in the present invention and is formed by cutting out a part of the inner wall portion 21b. The shape of the communication opening 24 is not limited to a rectangle as shown in the figure. In addition, there may be multiple communication openings 24.

[0035] The holding portion 26 is provided in the region including the communication portion 23 at the axial ends of the side portion 21, on the end opposite to the end where the communication port 24 is provided. The holding portion 26 has, for example, a crescent shape and covers a part of one end of the cylindrical member 20. Because the holding portion 26 is provided in the region including the communication portion 23, the discharge port 25 is provided at the end of the communication portion 23 opposite to the communication port 24. The communication portion 23 extends in the axial direction of the cylindrical member 20 from the communication port 24 to the discharge port 25. The upper surface of the holding portion 26 is a holding surface 26a. This results in a configuration where the holding surface 26a surrounds the discharge port 25. The holding surface 26a is inclined from the periphery of the cylindrical member 20 where the discharge port 25 is provided toward the end of the cylindrical member 20 where the communication port 24 is provided toward the axis of the cylindrical member 20. Furthermore, the number of discharge ports 25 is not limited to one; there may be multiple ports. Also, the shape of the discharge ports 25 is not limited to the roughly rectangular shape shown in the illustration; there may be various shapes such as circles, ovals, or star shapes.

[0036] The outer wall portion 21a has an outer diameter that is slightly larger at the end where the holding portion 26 is provided, while the inner wall portion 21b has an inner diameter that is the same at both ends in the axial direction. In other words, the side portion 21 has a tapered outer diameter, while its inner diameter is cylindrical.

[0037] <Pressing Member 30> Figure 6 is a view of the pressing member 30 shown in Figure 1, seen from diagonally above.

[0038] The pressing member 30 shown in Figure 1 is made of an elastic material and has a bottom portion 31 and a side portion 32, as shown in Figure 6.

[0039] The bottom portion 31 is circular, with a mountain-like shape where the central part is convex upwards.

[0040] The side portion 32 is positioned over the outer circumference of the bottom portion 31. The side portion 32 is curved so that its upper and lower ends protrude outward, and since the pressing member 30 is made of an elastic material, it can be deformed by external force so that the position of the upper and lower ends shifts toward the center of the side portion 32.

[0041] <Relationship between the container body 10, the cylindrical member 20, and the pressing member 30> The relationship between the container body 10, the cylindrical member 20, and the pressing member 30 described above will be explained below.

[0042] Figure 7 is a cross-sectional perspective view of the container 1 showing the state in which the contents dispensing device 2, which is configured by attaching a push member 30 to a cylindrical member 20, is attached to the container body 10.

[0043] As shown in Figure 7, the push-in member 30 shown in Figure 6 is installed so as to be housed in the cylindrical member 20 shown in Figures 3 to 5, and the cylindrical member 20 with the push-in member 30 installed is installed so as to be housed in the container body 10 shown in Figure 2.

[0044] The outer diameter of the pushing member 30 and the inner diameter of the inner wall portion 21b of the cylindrical member 20 are the same as each other or the outer diameter of the pushing member 30 is slightly larger. Therefore, as shown in FIG. 7, the pushing member 30 can be attached into the cylindrical member 20 such that the side surface portion 32 of the pushing member 30 faces the inner surface of the inner wall portion 21b of the cylindrical member 20. When the outer diameter of the pushing member 30 is slightly larger than the inner diameter of the inner wall portion 21b of the cylindrical member 20, the pushing member 30 is composed of an elastic member, so that the side surface portion 32 is deformed such that the positions of the upper and lower ends of the side surface portion 32 fluctuate toward the center side of the side surface portion 32, and the pushing member 30 can be attached into the cylindrical member 20.

[0045] Further, the inner diameters of both axial ends of the inner wall portion 21b of the cylindrical member 20 are the same as each other. That is, the side surface portion 21 has an inner diameter that is in a so-called tapered shape. Therefore, the pushing member 30 attached in the cylindrical member 20 can be moved in the axial direction of the cylindrical member 20 along the inner surface of the cylindrical member 20.

[0046] On the other hand, the outer diameter of the cylindrical member 20 and the inner diameter of the container body 10 are the same as each other or the inner diameter of the container body 10 is slightly larger. Also, as described above, the outer diameter and the inner diameter of both axial ends of the side surface portion 12 of the container body are slightly smaller at the end on the bottom 11 side. On the other hand, the outer diameter of both axial ends of the outer wall portion 21a of the cylindrical member 20 is slightly larger at the end where the holding portion 26 is provided. Therefore, as shown in FIG. 7, the cylindrical member 20 can be attached into the container body 10 by opposing the outer surface of the outer wall portion 21a of the cylindrical member 20 to the inner surface of the side surface portion 12 of the container body 10 such that the communication port 24 side of the cylindrical member 20 becomes the bottom 11 side of the container body 10.

[0047] Further, the axial length of the cylindrical member 20 is the same as the height inside the side surface portion 12 of the container body 10. Therefore, in a state where the cylindrical member 20 is attached in the container body 10, by abutting the end of the side surface portion 21 of the cylindrical member 20 on the side where the communication port 24 is provided against the bottom 11 of the container body 10, the height of the end of the side surface portion 21 of the cylindrical member 20 on the side where the holding portion 26 is provided can be aligned with the flange portion 13.

[0048] Also, in a state where the end portion on the side where the communication port 24 is provided on the side surface portion 21 of the cylindrical member 20 abuts against the bottom portion 11 of the container body 10, the inside of the inner wall portion 21b of the cylindrical member 20 and the communication portion 23 communicate with each other through the communication port 24.

[0049] In a state where the container discharging tool 2 configured by attaching the pushing member 30 to the cylindrical member 20 is attached to the container body 10, the bottom portion 31 of the pushing member 30 has a mountain shape that protrudes to the side opposite to the bottom portion 11 of the container body 10, and the bottom portion 11 of the container body 10 has the same mountain shape as the mountain shape of the bottom portion 31 of the pushing member 30.

[0050] <Explanation of the operation during use> The following will explain the usage method and the operation by use of the container 1 configured as described above.

[0051] The container 1 shown in FIG. 1 is used, for example, by being housed in an outer container. In that case, the container 1 may be removably housed in the outer container. As described above, the outer diameter of both axial ends of the side surface portion 12 of the container body 10 is slightly smaller at the end portion on the bottom portion 11 side. Therefore, it becomes easier to house and remove the container 1 from the outer container.

[0052] In a state where the container 1 is housed in the outer container, the mouth portion of the outer container may be opened and closed freely by an outer lid. For example, by screw-engaging the outer peripheral surface of the mouth portion of the outer container and the inner surface of the outer lid, the mouth portion of the outer container can be closed or opened.

[0053] Also, as described above, the container body 10 is provided with a flange portion 13 at the end portion on the side opposite to the bottom portion 11 among both axial ends of the side surface portion 12, and the flange portion 13 has a shape that spreads outward from the end portion of the side surface portion 12. Therefore, the container 1 can be held so as not to fall into the mouth portion by hooking the flange portion 13 on the upper surface of the mouth portion of the outer container.

[0054] Cosmetics and other contents are contained in the space formed between the side portion 21 of the cylindrical member 20, the bottom portion 11 of the container body 10, and the bottom portion 31 of the pressing member 30. As described above, the outer diameter of the pressing member 30 and the inner diameter of the inner wall portion 21b of the cylindrical member 20 are the same or the outer diameter of the pressing member 30 is slightly larger. Therefore, airtightness is ensured between the side portion 32 of the pressing member 30 and the inner surface of the inner wall portion 21b of the cylindrical member 20. In particular, when the outer diameter of the pressing member 30 is slightly larger than the inner diameter of the inner wall portion 21b of the cylindrical member 20, the pressing member 30 is made of an elastic material, so that the position of the upper and lower ends of the side portion 32 of the pressing member 30 moves toward the center of the side portion 32, and the restoring force presses it against the inner surface of the inner wall portion 21b of the cylindrical member 20. This ensures airtightness between the side portion 32 of the pressing member 30 and the inner surface of the inner wall portion 21b of the cylindrical member 20. Therefore, even if the container 1 is turned upside down so that the bottom portion 11 of the container body 10 is facing upwards, the contents contained in the container 1 are less likely to leak out from between the pressing member 30 and the cylindrical member 20. In order to ensure airtightness between the pressing member 30 and the inner surface of the cylindrical member 20, it is not necessary to construct the entire pressing member 30 from an elastic material; only the side portion 32 may be made from an elastic material as an example of an elastic part.

[0055] When using the contents contained in container 1, push the push member 30 towards the bottom 11 side of the container body 10.

[0056] Figure 8 is a diagram illustrating the method of use and the effects of using the contents contained in container 1, and is a cross-sectional perspective view of container 1.

[0057] To use the contents contained in container 1, the push member 30 is pushed in with a finger in the direction indicated by arrow A in Figure 8. At this time, the push member 30 moves toward the bottom 11 side of the container body 10 while maintaining airtightness between the side portion 32 of the push member 30 and the inner surface of the inner wall portion 21b of the cylindrical member 20. In other words, the push member 30 is provided to be movable inside the cylindrical member 20 along the inner surface of the cylindrical member 20 while maintaining a predetermined airtightness between it and the inner surface of the cylindrical member 20. Therefore, even when pushing the push member 30 toward the bottom 11 side of the container body 10 in order to use the contents contained in container 1, the contents contained in container 1 are less likely to leak out from between the push member 30 and the cylindrical member 20.

[0058] In the case where the bottom 31 of the push-in member 30 is flat, if the fingernail is long, it may be difficult to push the push-in member 30 into the bottom 11 side of the container body 10 because the fingernail hits the bottom 31. On the other hand, as described above, the bottom 11 of the push-in member 30 in this embodiment has a mountain-like shape with a protruding central portion. Therefore, even if the fingernail is long, the mountain-like slope makes it easier to push with the finger. Specifically, because the bottom 11 is mountain-like, its central portion is the highest, so if you press the central portion of the bottom 11 with your finger, the tip of your fingernail will face the lower part of the bottom 11, making it less likely to hit the bottom 11, and preventing the tip of your fingernail from getting in the way and making it difficult to push the push-in member 30.

[0059] As the push member 30 is pushed in the direction indicated by arrow A in Figure 8 and moves toward the bottom 11 of the container body 10, the contents contained in the space formed between the side portion 21 of the cylindrical member 20, the bottom 11 of the container body 10, and the bottom 31 of the push member 30 move through the communication opening 24 in the direction indicated by arrow B in Figure 8 and enter the communication section 23. Here, the space formed between the side portion 21 of the cylindrical member 20, the bottom 11 of the container body 10, and the bottom 31 of the push member 30 has no part that communicates with the outside except for the communication opening 24. Therefore, as the push member 30 moves toward the bottom 11 of the container body 10, the contents contained in the space formed between the side portion 21 of the cylindrical member 20, the bottom 11 of the container body 10, and the bottom 31 of the push member 30 enter the communication section 23 through the communication opening 24.

[0060] The communication portion 23 has one end that communicates with the space formed between the side portion 21 of the cylindrical member 20, the bottom portion 11 of the container body 10, and the bottom portion 31 of the push-in member 30 via a communication opening 24, and the other end that communicates with the outside of the container 1 via a discharge opening 25.

[0061] Therefore, the contents that enter the communication section 23 through the communication opening 24 are moved to the discharge opening 25 as the pushing member 30 is further pushed towards the bottom 11, and are discharged from the discharge opening 25 in the direction indicated by arrow C in Figure 8.

[0062] In this embodiment, by moving the pushing member 30 along the inner surface of the cylindrical member 20, the contents contained in the container 1 enter the communicating portion 23 and are discharged from the discharge port 25. As a result, there is no need to put your fingers into the container 1 to scoop out the contents, making it possible to use it hygienically. In addition, a separate tool for removing the contents from the container 1 is not required. This eliminates the need to carry a separate tool for removing the contents. Furthermore, there is no need to provide a structure or space in the container 1 for holding the removal tool, so the container 1 does not become larger.

[0063] Furthermore, by pushing the push member 30 towards the bottom 11 of the container body 10, the contents contained in the container 1 are discharged from the discharge port 25, allowing for intuitive recognition of the discharge of contents. Moreover, since the amount discharged from the discharge port 25 corresponds to the amount the push member 30 is pushed towards the bottom 11 of the container body 10, it becomes easy to adjust the amount of contents dispensed. In addition, the remaining amount of contents can be recognized by the position of the push member 30.

[0064] When the contents contained in container 1 are discharged from the discharge port 25, as described above, the holding surface 26a surrounding the discharge port 25 causes the discharged contents to be discharged onto the holding surface 26a. Therefore, the contents discharged from the discharge port 25 can be temporarily held on the holding surface 26a. In addition, the amount of contents discharged from the discharge port 25 can be recognized by the amount of contents held on the holding surface 26a.

[0065] Afterward, the contents held on the holding surface 26a of the holding part 26 are wiped off with a finger and applied to the skin, etc. Here, as described above, the holding surface 26a is inclined from the periphery of the cylindrical member 20, where the discharge port 25 is provided, toward the end side where the communication port 24 of the cylindrical member 20 is provided, toward the center of the axis of the cylindrical member 20. Therefore, for example, if the contents are wiped off with the fingertip facing toward the center of the axis of the cylindrical member 20, it becomes easier to wipe off the contents held on the holding surface 26a. The inclination angle of the holding surface 26a may be, for example, 15° with respect to a plane (horizontal plane) perpendicular to the axial direction of the cylindrical member 20.

[0066] Furthermore, a step may be provided around the holding surface 26a such that the portion facing the outer wall portion 21a is higher. With such a configuration, when wiping off the contents held on the holding surface 26a, the contents are less likely to drip off the holding surface 26a.

[0067] In this way, the contents contained in container 1 are discharged from the discharge port 25, and as the amount of contents in container 1 decreases, the bottom 31 of the pressing member 30 approaches the bottom 11 of the container body 10. When there are no more contents in container 1, the bottom 31 of the pressing member 30 comes into contact with the bottom 11 of the container body 10. Here, the bottom 31 of the pressing member 30 is shaped like a mountain, with the central part convex on the opposite side of the bottom 11, in order to make it easier to press the pressing member 30 with a finger. Therefore, if the bottom 11 of the container body 10 is flat, when the bottom 31 of the pressing member 30 comes into contact with the bottom 11 of the container body 10, a space will be created between the bottom 31 of the pressing member 30 and the bottom 11 of the container body 10 below the convex part of the bottom 31 of the pressing member 30, and the contents will remain in that space. Therefore, in this embodiment, as described above, the bottom 11 is shaped like the same mountain as the bottom 31 of the pressing member 30. Therefore, when the bottom 31 of the push-in member 30 is in contact with the bottom 11 of the container body 10, the mountain-shaped bottom 31 and the mountain-shaped bottom 11 overlap, allowing the contents stored in the container 1 to be used up completely.

[0068] The dispenser 2 containing the contents described above may also be provided as a refill. In that case, with the contents contained in the space surrounded by the cylindrical member 20 and the push-in member 30, the end of the cylindrical member 20 on the side where the communication opening 24 is provided is covered with an aluminum seal. When in use, the aluminum seal is peeled off and the dispenser 2 containing the contents is attached by placing it in the container body 10. In this case, as described above, the outer and inner diameters of the cylindrical ends of the side portion 12 of the container body 10 are slightly smaller at the end on the bottom portion 11 side. On the other hand, the outer wall portion 21a of the cylindrical member 20 is slightly larger at the end where the holding portion 26 is provided. Therefore, the cylindrical member 20 is easy to remove from the container body 10 and easy to attach to the container body 10.

[0069] In this way, after the contents have been used up, the container body 10 can be reused repeatedly simply by replacing the contents dispensing device 2.

[0070] (Other Embodiments) Figure 9 is a cross-sectional perspective view showing another embodiment of a container having a contents dispensing device of the present invention.

[0071] As shown in Figure 9, this embodiment is a container 101 that differs from those shown in Figures 1 to 8 in its communication structure for allowing the contents contained within the container to enter the communication portion 23. In this embodiment, the axial length of the cylindrical member 120 is shorter than the inner height of the side portion 12 of the container body 110, thereby creating a gap 124 between the inner wall portion 121b and the bottom portion 111 of the container body 110. The end of the outer wall portion 121a of the cylindrical member 120 opposite to the discharge port 25 abuts against a step 114 provided on the bottom portion 111 of the container body 110, and there is no gap between the outer wall portion 121a and the bottom portion 111 of the container body 110.

[0072] Furthermore, the bottom 131 of the push-in member 130 and the bottom 111 of the container body 110 are both flat in shape.

[0073] In the container 101 configured as described above, as the pushing member 130 is pushed in and moves toward the bottom 111, the contents contained in the space formed between the cylindrical member 120, the bottom 111 of the container body 110, and the bottom 131 of the pushing member 130 enter the communication section 23 through the gap 124. The contents that have entered the communication section 23 through the gap 124 then move to the discharge port 25 as the pushing member 130 is further pushed toward the bottom 111, and are discharged from the discharge port 25.

[0074] (Example of application) Figures 10 and 11 show examples of applications for the contents dispensing device. Figure 10 is an overall perspective view, and Figure 11 shows the device with the lid 204 shown in Figure 10 open.

[0075] As shown in Figure 10, the container bodies 10 and 110 described above can be used as a container body 210 whose opening is closed by a lid 204. The container body 210 houses a contents dispensing device 202 consisting of a cylindrical member 220 and a pressing member 230, similar to the container bodies 10 and 110 described above.
