Description

[Technical Field]

[0001] The present invention relates to a dispensing member. [Background technology]

[0002] Conventionally, as shown in Patent Document 1 below, for example, a rising-inner-plate type dispensing container has been known, which comprises a main container body in which the contents are stored, a middle plate provided inside the main container body that rises as the contents decrease, and a dispenser provided at the mouth of the main container body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-362659 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, inner tray lifting type dispensing containers are often discarded after the contents are used up, and in recent years, there has been a demand for the contents to be refilled inside the container body in order to reduce the amount of plastic waste.

[0005] The present invention provides a pouring member that allows contents to be easily refilled into the inside of a container body provided with an inner tray that rises as the contents decrease. [Means for solving the problem]

[0006] A dispensing member according to one aspect of the present invention comprises a cylindrical attachment section with a top that is attached to the mouth of a refill container that contains the contents to be refilled into the container; a dispensing section that extends downward from the attachment section and is inserted into the refill container; and a connecting section that extends upward from the attachment section and can be attached to the mouth of the refill container that has been removed from the attachment section. The top wall of the attachment section is formed in an annular shape, and the inside of the dispensing section and the inside of the connecting section are connected through the inside of the top wall. The container comprises a container body in which the contents are stored, and an inner plate that is provided inside the container body and rises as the contents decrease. When the attachment section that has been removed from the mouth of the refill container is attached to the mouth of the container body, the dispensing section is inserted into the inside of the container body while pushing down the inner plate.

[0007] When the attachment tube part removed from the mouth of the refill container is attached to the mouth of the container body, the dispensing tube part is inserted into the inside of the container body while pushing down the raised inner plate.Therefore, when the mouth of the refill container containing the contents is attached to the connecting tube part and the contents of the refill container are transferred into the container body through the inside of the top wall of the attachment tube part and the inside of the dispensing tube part, the inner plate can be lowered and returned to its original position without performing any other operations, and the contents can be easily transferred into the inside of the container body which is provided with an inner plate which rises as the contents decrease.

[0008] The mounting tube portion may be provided with an abutment portion that abuts against the container body in the vertical direction when attached to the mouth of the container body, and positions the lower surface of the top wall of the mounting tube portion above the upper opening edge of the mouth of the container body.

[0009] Since the mounting tube has a stop portion, when the mounting tube is attached to the mouth of the container body, it is possible to create a vertical gap between the underside of the top wall of the mounting tube and the upper opening edge of the mouth of the container body, and when the contents of the refill container flow into the inside of the container body, the air inside the container body can flow out smoothly through this gap.

[0010] A cylindrical inner plug member is fitted inside the mouth of the container body, and a plurality of protrusions protruding radially inward are intermittently provided along the circumferential direction on the inner surface of the inner plug member, and when the mounting tube portion is mounted on the mouth of the container body, the outer surface of the dispensing tube portion may be moved radially inward from the inner surface of the inner plug member while abutting the protrusions.

[0011] When the attachment tube is attached to the mouth of the container, the outer surface of the dispensing tube abuts against a plurality of ridges arranged intermittently along the circumferential direction and moves radially inward from the inner surface of the inner plug member. Therefore, when the contents of the refill container flow into the inside of the container, air inside the container can smoothly flow out between the outer surface of the dispensing tube and the inner surface of the inner plug member, as well as between adjacent ridges in the circumferential direction. Furthermore, after refilling the contents, when the attachment tube is removed from the mouth of the container and the dispensing tube is pulled up from the container, the ridges can scrape off the contents adhering to the outer surface of the dispensing tube, making it easy to refill even highly viscous contents. [Effects of the Invention]

[0012] According to one aspect of the present invention, the contents can be easily refilled into the inside of the container body, which is provided with an inner tray that rises as the contents decrease. [Brief explanation of the drawings]

[0013] [Figure 1] 1 is a vertical cross-sectional view of a refillable container with a dispensing member shown as one embodiment. [Figure 2] FIG. 10 is a view showing the process of attaching the mounting tube to the opening of the container body. [Figure 3] 10 is a view showing the state in which the mounting tube is attached to the mouth of the main container body and the mouth of the refill container is attached to the connecting tube. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, a pouring member according to one embodiment of the present invention will be described with reference to the drawings. 1, the dispensing member 1 according to this embodiment includes an attachment tube portion 11, a dispensing tube portion 12, and a connecting tube portion 13. The attachment tube portion 11, the dispensing tube portion 12, and the connecting tube portion 13 are arranged coaxially with a common axis.

[0015] Hereinafter, this common axis will be referred to as the central axis O, the side of the connecting tube portion 13 along the central axis O will be referred to as the upper side, the side of the mounting tube portion 11 along the central axis O will be referred to as the lower side, and the direction along the central axis O will be referred to as the up-down direction. The direction that intersects with the central axis O when viewed from the up-down direction will be referred to as the radial direction, and the direction that goes around the central axis O when viewed from the up-down direction will be referred to as the circumferential direction.

[0016] The mounting tube 11 is mounted on the opening 10a of a refill container 10 that contains the contents to be refilled into the main container 20 (see FIGS. 2 and 3).

[0017] Here, the body 10b of the refillable container 10 is formed so as to be deformable in the radial direction. In the illustrated example, the refillable container 10 is a tube container. Note that the refillable container 10 may also be a self-supporting cylindrical body with a bottom. A cylindrical first inner plug member 15 is fitted inside the mouth portion 10a of the refillable container 10. A plurality of ridges 15a projecting radially inward are provided intermittently along the circumferential direction on the inner circumferential surface of the first center plug member 15. The ridges 15a may be provided so as to extend continuously around the entire periphery of the inner circumferential surface of the first center plug member 15. The plurality of ridges 15a extend upward from one circumferential side to the other circumferential side. Of two ridges 15a adjacent to each other in the circumferential direction, the end portion on the other circumferential side of the ridge 15a located on one circumferential side is located above and at the same circumferential position as the end portion on one circumferential side of the ridge 15a located on the other circumferential side. A flange portion 15b that protrudes radially outward and extends circumferentially over the entire length is formed at the upper end of the first center plug member 15. The flange portion 15b is placed on the upper opening edge of the mouth portion 10a of the refill container 10.

[0018] 2 and 3, the container 20 comprises a container body 21 in which the contents are stored, and an inner tray 22 that is provided inside the container body 21 and rises as the contents decrease. The contents are stored in a portion of the inside of the container body 21 that is located above the inner tray 22. Container body 21 is configured with mouth 21a, shoulder 21b, and body 21c, which are arranged coaxially and connected in this order from top to bottom. A second center plug member (center plug member) 23, which has the same shape and size as first center plug member 15, is fitted inside mouth 21a of container body 21. The inner circumferential surface of second center plug member 23 is provided with a plurality of ridges 23a, which have the same shape and size as ridges 15a. A flange portion 23b that protrudes radially outward and extends over the entire circumferential length is formed at the upper end of second center plug member 23. Flange portion 23b is placed on the upper opening edge of mouth portion 21a of container body 21.

[0019] 1, the mounting tube 11 is formed in a topped cylindrical shape with an annular top wall 11a. The lower surface of the top wall 11a abuts against the upper surface of the flange portion 15b. The inner surface of the peripheral wall 11b of the mounting tube 11 is formed with a female thread that screws into the opening portion 10a. As shown in Fig. 3, the cylindrical attachment portion 11 is provided with an abutment portion 14 that abuts against the mouth 21a of the container body 21 in the vertical direction when attached to the mouth 21a of the container body 21, positioning the lower surface of the top wall 11a of the cylindrical attachment portion 11 above the upper opening edge of the mouth 21a of the container body 21. In the illustrated example, the cylindrical attachment portion 11 is provided with an outer tube 11c that surrounds the peripheral wall 11b from the outside in the radial direction, and the lower opening edge of the outer tube 11c forms the abutment portion 14. The lower end of the outer tube 11c is positioned below the lower end of the peripheral wall 11b. As shown in Fig. 1, the abutment portion 14 is positioned above and vertically opposed to the outer peripheral surface of the shoulder portion 10c of the refillable container 10 that connects the mouth 10a and the body 10b. The mounting tube portion 11 may not be provided with the outer tube 11c, and the lower end opening edge of the peripheral wall 11b may be used as the abutment portion 14.

[0020] The pouring tube portion 12 extends downward from the mounting tube portion 11 and is inserted into the refillable container 10. The pouring tube portion 12 extends downward from the inner peripheral edge of the top wall 11a of the mounting tube portion 11. The upper end of the pouring tube portion 12 extends radially inward as it extends downward. The pouring tube portion 12 is inserted into the inside of the body portion 10b of the refillable container 10 through the inside of the first center plug member 15. The lower end of the pouring tube portion 12 has multiple through holes 12a that penetrate radially and are spaced apart circumferentially. The through holes 12a open at the lower end opening edge of the pouring tube portion 12. When the mounting tube portion 11 is attached to the mouth portion 10a of the refill container 10, the outer surface of the pouring tube portion 12 is in contact with the protrusion portion 15a and is spaced radially inward from the inner surface of the first center plug member 15.

[0021] The connecting tubular portion 13 extends upward from the mounting tubular portion 11 and is formed so that the mouth portion 10a of the refillable container 10 removed from the mounting tubular portion 11 can be attached to it. The connecting tubular portion 13 is formed to have the same shape and size as the peripheral wall 11b of the mounting tubular portion 11. The inner peripheral surface of the connecting tubular portion 13 is formed with a female thread portion into which the mouth portion 10a of the refillable container 10 can be screwed. The inside of the connecting tubular portion 13 communicates with the inside of the top wall 11a of the mounting tubular portion 11. A cylindrical cap 16 with a top is removably screwed onto the female thread of the connecting cylindrical part 13. A seal cylinder 16a is formed on the top wall of the cap 16, extending downward and removably fitted inside the top wall 11a of the mounting cylindrical part 11 in a liquid-tight manner.

[0022] Next, a method for refilling the contents of the refill container 10 into the main container 20 will be described.

[0023] First, the cap 16 is rotated circumferentially relative to the connecting tubular portion 13 in the loosening direction, the cap 16 is removed from the connecting tubular portion 13, and the mounting tubular portion 11 is rotated circumferentially relative to the mouth portion 10a of the refillable container 10 in the loosening direction, thereby releasing the screwing of the mounting tubular portion 11 from the mouth portion 10a of the refillable container 10. Next, when the dispensing member 1 is pulled up toward the refill container 10, the outer surface of the dispensing tube portion 12 slides against the protrusion portion 15a of the first inner plug member 15, causing the contents adhering to the outer surface of the dispensing tube portion 12 to be squeezed off by the protrusion portion 15a. As a result, the dispensing member 1 is removed from the refill container 10.

[0024] When attaching the attachment tube portion 11 removed from the mouth portion 10a of the refill container 10 to the mouth portion 21a of the main container body 21, the pouring tube portion 12 is inserted into the inside of the main container body 21 through the inside of the second inner plug member 23. 2 and 3, with the lower opening edge of the pouring tubular portion 12 abutting against the inner plate 22, the pouring tubular portion 12 pushes the inner plate 22 down and returns to its original position. Furthermore, the outer peripheral surface of the pouring tubular portion 12 abuts against the protrusion 23a of the second inner plug member 23 and is spaced radially inward from the inner peripheral surface of the second inner plug member 23. Furthermore, when the attachment tubular portion 11 is attached to the mouth 21a of the container body 21, the abutment portion 14 of the attachment tubular portion 11 abuts against the outer peripheral surface of the shoulder 21b of the container body 21 in the vertical direction. As a result, the lower surface of the top wall 11a of the attachment tubular portion 11 is spaced upward from the upper surface of the flange 23b of the second inner plug member 23, which is placed on the upper opening edge of the mouth 21a of the container body 21.

[0025] Furthermore, the mouth portion 10a of the refillable container 10 is attached to the inside of the connecting tube portion 13. This allows the inside of the refillable container 10 to communicate with the inside of the container body 21 through the inside of the top wall 11a of the attaching tube portion 11, the inside of the pouring tube portion 12, and the through-hole 12a of the pouring tube portion 12. Then, the contents of the refillable container 10 are allowed to flow into the container body 21 by, for example, shrinking and deforming the body portion 10b of the refillable container 10, while air is allowed to flow out from the container body 21 through vertical gaps between the outer circumferential surface of the pouring tube portion 12 and the inner circumferential surface of the second center plug member 23, between adjacent circumferential protrusions 23a, and between the underside of the top wall 11a of the attaching tube portion 11 and the upper surface of the flange portion 23b of the second center plug member 23.

[0026] After the contents have been refilled into the container body 21, the mounting tube portion 11 is rotated circumferentially in the loosening direction relative to the mouth portion 21a of the container body 21, thereby releasing the screwed connection of the mounting tube portion 11 with the mouth portion 21a of the container body 21. Next, when the dispensing member 1 is pulled up relative to the container 20, the outer surface of the dispensing tube portion 12 slides against the protrusion portion 23a of the second inner plug member 23, causing the contents adhering to the outer surface of the dispensing tube portion 12 to be squeezed off by the protrusion portion 23a. Then, by attaching a dispenser (not shown) to the opening 21a of the main container body 21, a lift-up tray type dispensing container is obtained in which the main container body 21 is filled with the contents.

[0027] As described above, according to the dispensing member 1 of this embodiment, when the attachment tube portion 11 removed from the mouth portion 10a of the refill container 10 is attached to the mouth portion 21a of the main container body 21, the dispensing tube portion 12 is inserted into the inside of the main container body 21 while pushing down the raised inner plate 22.Therefore, when the mouth portion 10a of the refill container 10 containing the contents is attached to the connecting tube portion 13 and the contents of the refill container 10 are transferred into the main container body 21 through the inside of the top wall 11a of the attachment tube portion 11 and the inside of the dispensing tube portion 12, it is possible to lower the inner plate 22 and return it to its original position without performing any other operations, and the contents can be easily transferred into the inside of the main container body 21 which is provided with the inner plate 22 which rises as the contents decrease.

[0028] Since the mounting tube portion 11 has an abutment portion 14, when the mounting tube portion 11 is attached to the mouth portion 21a of the main container body 21, it is possible to create a vertical gap between the underside of the top wall 11a of the mounting tube portion 11 and the upper opening edge of the mouth portion 21a of the main container body 21, and when the contents of the refill container 10 flow into the inside of the main container body 21, the air inside the main container body 21 can flow out smoothly through this gap.

[0029] When the attachment tube portion 11 is attached to the mouth 21a of the container body 21, the outer surface of the dispensing tube portion 12 abuts against a plurality of protrusions 23a arranged intermittently along the circumferential direction and moves radially inward from the inner surface of the second inner plug member 23. Therefore, when the contents of the refill container 10 flow into the inside of the container body 21, the air inside the container body 21 can smoothly flow out between the outer surface of the dispensing tube portion 12 and the inner surface of the second inner plug member 23, and between adjacent protrusions 23a in the circumferential direction.Furthermore, after the contents have been refilled, when the attachment tube portion 11 is removed from the mouth 21a of the container body 21 and the dispensing tube portion 12 is pulled up from the container body 21, the protrusions 23a can scrape off the contents adhering to the outer surface of the dispensing tube portion 12, making it easy to refill even highly viscous contents.

[0030] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0031] For example, the mounting tube portion 11 does not need to have the abutment portion 14 . The refill container 10 does not need to be provided with the first inner plug member 15, and the main container body 21 does not need to be provided with the second inner plug member 23.

[0032] In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and the above-described variations may be combined as appropriate.
