Description

[Technical field]

[0001] The present invention relates to a dispensing container and a replacement container for use with the dispensing container. [Background technology]

[0002] Conventionally, there is known a discharge container that includes a container body that stores the content liquid and a discharge part that sucks up the content liquid and discharges it to the outside (for example, see Patent Document 1). The discharge part includes an attachment part that is attached to the cylindrical mouth part of the container body, a pump that sucks up the content liquid, and a pipe that extends downward from the pump and sucks in the content liquid. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2023-81215 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the conventional dispensing containers described above, after the liquid content of the container body has been used up, the dispensing part can be removed from the container body and attached to a replacement container body filled with the liquid content, thereby making it possible to reuse the dispensing part. However, when the discharge part is removed from the container body, the liquid content adhering to the pump and pipe of the discharge part may fall outside the discharge container, soiling the surrounding area. In particular, if the liquid content has a high viscosity, the liquid content is likely to remain in the discharge part and may fall. In addition, it may be possible to scrape off the liquid content adhering to the discharge part, for example, with a scraping member provided in the container body, but since the outer diameter of the pump and the outer diameter of the pipe are different, it is difficult to scrape off the liquid content from both the pump and the pipe.

[0005] In view of these points, an object of the present invention is to provide a dispensing container that can prevent the content liquid from falling outside the dispensing container from the discharge part when the discharge part is detached from the container body. [Means for solving the problem]

[0006] The discharge container comprises a container body that stores the liquid content, and a discharge part that sucks up the liquid content and discharges it to the outside, the discharge part comprising an attachment part that is attached to a cylindrical mouth part of the container body, a pump that sucks up the liquid content, and a pipe that extends downward from the pump to suck in the liquid content. The discharge container is provided with an inner plug that extends into the container body through the mouth part, and a scraping member supported by the inner plug, and the inner plug has a fixing part that is fixed to the mouth part, and a pipe that extends from the fixing part into the container body. The container further comprises a cylindrical portion extending from the nozzle, the scraping member being stored within the cylindrical portion and blocking the lower portion of the cylindrical portion, the pump being stored within the cylindrical portion above the scraping member, and when the discharge portion is attached to the mouth portion, the pipe is pressed into a pipe hole provided in the scraping member and extends into the container body, and when the discharge portion is removed from the mouth portion, the content liquid adhering to the pipe is scraped off by the pipe hole as the pipe is pulled out of the pipe hole. Effect of the Invention

[0007] According to the discharge container of the present invention, when the discharge part is detached from the container body, it is possible to prevent the content liquid from dropping from the discharge part to the outside of the discharge container. [Brief description of the drawings]

[Figure 4]FIG. 2 is a cross-sectional view showing a replacement container used for the dispensing container. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of a discharge container according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a dispensing container 10 according to an embodiment of the present invention. The discharge container 10 comprises a container body 11 for storing the liquid contents L, a discharge section 12 for sucking up the liquid contents L and discharging it to the outside, an inner stopper 13 extending into the container body 11 through the mouth section 11a of the container body 11, and a scraping member 14 supported by the inner stopper 13. The liquid content L is a highly viscous liquid such as, for example, cosmetic cream or liquid foundation.

[0010] Fig. 2 is a cross-sectional view showing the dispensing container 10 in a state where the content liquid L has decreased due to use. Fig. 3 is a cross-sectional view showing an intermediate stage when the discharge part 12 is removed from the container body 11. Figs. 2 and 3 show a state where the remaining content liquid L is attached to the outer periphery of the pipe 22 and the inner surface of the container body 11. 1 to 3, container body 11 comprises a container bottom wall 15, a cylindrical body 16 extending upward from the peripheral edge of container bottom wall 15, a shoulder 17 extending radially inward from the upper end of body 16, and a mouth 11a. The mouth portion 11a is cylindrical and extends upward from the center of the shoulder portion 17. An outer engagement portion 11b that engages with the discharge portion 12 is provided on the outer periphery of the mouth portion 11a. The outer engagement portion 11b is a male thread portion formed on the outer periphery of the mouth portion 11a. 1, the discharge container 10 is shown in an upright position in which the discharge container 10 is placed upright so that the axis 11c of the mouth part 11a is oriented in the vertical direction. The axis 11c is the center line of the mouth part 11a. The axis 11c is arranged coaxially with the axis of the body part 16.

[0011] The discharge part 12 includes a pump 20 disposed inside the mouth part 11a, a push-down head 21 that is pushed down, a pipe 22 that extends downward from the pump 20, and an attachment cap 23 (attachment part) that is attached to the mouth part 11a.

[0012] The pump 20 comprises a cylindrical cylinder 25, a stem 26 connected to the pressing head 21, a piston guide 27 connected to the stem 26, a piston 28 housed within the cylinder 25, a biasing member 29 that biases the stem 26 upward, and a support cylinder 30 that supports the stem 26.

[0013] The cylinder 25 is cylindrical and arranged coaxially with the axis 11c. The cylinder 25 includes a cylinder body 25a that houses the piston 28 and other components, a pipe attachment portion 25b provided below the cylinder body 25a, and an annular flange portion 25c that extends radially outward from the upper end of the cylinder body 25a. A packing 25d is attached to the cylinder body 25a so as to abut against the lower surface of the flange portion 25c. An air hole 25e is provided at the upper part of the cylinder body 25a, penetrating the cylinder body 25a in the radial direction.

[0014] The stem 26 is a cylindrical member that extends upward from the upper portion of the cylinder body 25a. The stem 26 is disposed coaxially with the axis 11c. The upper end of the stem 26 is connected to the lower portion of the press-down head 21.

[0015] The piston guide 27 is a cylindrical member disposed coaxially with the axis 11c. The piston guide 27 is connected to the stem 26 by fitting an upper portion of the piston guide 27 into the cylindrical interior of the stem 26. The lower end of the piston guide 27 is closed. The lower part of the piston guide 27 extends below the stem 26 within the cylinder main body 25a. The lower part of the piston guide 27 is provided with a hole 27a that penetrates the piston guide 27 in the radial direction, and a guide flange 27b that supports the piston 28 from below.

[0016] The piston 28 is supported by a piston guide 27 and moves up and down within the cylinder main body 25a.

[0017] The biasing member 29 is disposed in a compressed state between the lower end of the cylinder body portion 25a and the piston guide 27. The biasing member 29 pushes the piston guide 27 upward by the repulsive force of compression, and biases the stem 26 upward via the piston guide 27. The biasing member 29 is a coil spring.

[0018] The support cylinder 30 includes a cylinder portion 30a that fits onto the inner periphery of the upper end portion of the cylinder main body portion 25a, and an outer periphery flange portion 30b that extends radially outward from the outer periphery of the cylinder portion 30a. The support tube 30 is positioned in the up-down direction relative to the cylinder 25 by the outer peripheral flange portion 30b abutting against the flange portion 25c from above.

[0019] The lower portion of the stem 26 is supported by a support tube 30 . An upper portion 30c of the cylindrical portion 30a extends upward beyond the cylinder 25. The upper portion 30c is formed with a smaller diameter than the lower portion of the cylindrical portion 30a, forming a step on the inner peripheral side, and this step presses the lower portion of the stem 26 from above.

[0020] An outlet 21a for discharging the content liquid L to the outside is provided on the side surface of the press-down head 21. The outlet 21a communicates with the inside of the cylinder main body 25a via a flow path in the press-down head 21, a stem 26, and a piston guide 27.

[0021] The pipe 22 is attached to the pipe mounting portion 25b by fitting an upper end portion of the pipe 22 into the inner periphery of the pipe mounting portion 25b of the cylinder 25. The pipe 22 extends straight downward from the pipe mounting portion 25b to the vicinity of the container bottom wall 15. The pipe 22 is disposed coaxially with the axis 11c. The outer diameter of the pipe 22 is smaller than the outer diameter of the cylinder main body 25a. The lower end 22a of the pipe 22 is formed in a tapered shape that tapers toward the lower end.

[0022] The mounting cap 23 comprises a cylindrical side wall portion 23a that surrounds the mouth portion 11a, a cap upper wall portion 23b that extends radially inward from the upper end of the side wall portion 23a, a stem hole 23c that penetrates vertically through the center of the cap upper wall portion 23b, and an upper side wall portion 23d that extends upward from the peripheral edge of the cap upper wall portion 23b. An inner engagement portion 23f that engages with the outer engagement portion 11b of the mouth portion 11a is provided on the inner periphery of the side wall portion 23a. The inner engagement portion 23f is a female thread portion.

[0023] An inner plug attachment portion 11d having a smaller diameter than the outer engagement portion 11b is provided at the upper end of the mouth portion 11a. The inside plug 13 includes a fixing part 31 fixed to the upper end of the mouth part 11a including the inside plug mounting part 11d, a cylindrical part 32 extending from the fixing part 31 through the mouth part 11a into the container body 11, and a bottom wall 33 closing the lower surface of the cylindrical part 32. A bottom hole 33a penetrating the bottom wall 33 is provided in the center of the bottom wall 33. A cylinder 25 is housed inside the cylindrical part 32.

[0024] The fixing portion 31 is formed in a hook shape along the outer circumferential surface of the inside plug attachment portion 11d, the upper surface of the mouth portion 11a, and the inner circumferential surface of the mouth portion 11a. The fixing portion 31 is an annular portion provided along the mouth portion 11a.

[0025] The cylindrical portion 32 extends downward from the fixing portion 31 located inside the mouth portion 11a. The cylindrical portion 32 is disposed coaxially with the axis 11c. An upper end 32a of the cylindrical portion 32 is formed in a tapered shape that is inclined so as to approach the cylinder 25 as it extends downward from the fixed portion 31. The portion of the tubular portion 32 below the upper end portion 32a extends downward along the outer circumferential surface of the cylinder main body portion 25a.

[0026] In detail, the cylindrical portion 32 includes an upper cylindrical portion 34 that houses the pump 20, and a lower cylindrical portion 35 that is attached to the lower portion of the upper cylindrical portion 34. The upper cylindrical portion 34 includes the upper end portion 32a, a first cylindrical portion 34a that houses the cylinder body portion 25a, and a second cylindrical portion 34b that houses the pipe attachment portion 25b below the first cylindrical portion 34a. The fixing portion 31 is provided at the upper end of the upper cylindrical portion 34. The outer diameter of the second cylindrical portion 34b is smaller than the outer diameter of the first cylindrical portion 34a. Therefore, a step 34c is formed at the lower end of the first cylindrical portion 34a where the first cylindrical portion 34a protrudes radially outward relative to the second cylindrical portion 34b.

[0027] The lower cylindrical portion 35 is attached to the upper cylindrical portion 34 by fitting the second cylindrical portion 34b of the upper cylindrical portion 34 into the inner circumference of the lower cylindrical portion 35. The second cylindrical portion 34b is a fitting portion provided on the lower portion of the upper cylindrical portion 34. The upper end of the lower cylindrical portion 35 abuts against the step portion 34c. The lower cylindrical portion 35 extends downward further than the second cylindrical portion 34b, and the bottom wall 33 is provided at the lower part of the lower cylindrical portion 35. The lower cylindrical portion 35 and the bottom wall 33 are integrally formed. The bottom wall 33 has an annular projection 33b that projects upward from the periphery of the bottom hole 33a.

[0028] The scraping member 14 is housed in the lower part of the cylindrical portion 32 and closes the lower part of the cylindrical portion 32 . The scraping member 14 has a cylindrical shape that fits the internal shape of the tubular portion 32 . The cylindrical portion 32 has a pipe hole 14a into which the pipe 22 is press-fitted from above. The pipe hole 14a is a hole that vertically passes through the center of the scraping member 14, and is disposed coaxially with the axis 11c.

[0029] The scraping member 14 is a porous body with closed cells. This porous body does not allow the content liquid L to pass through it easily, but allows air to pass through it. The scraping member 14 is, for example, a sponge formed by foaming a synthetic resin such as polyurethane, and can elastically deform relatively greatly against a compressive force.

[0030] The scraping member 14 is housed in the lower cylindrical portion 35 of the cylindrical portion 32, and is sandwiched between the bottom wall 33 and the lower end portion of the second cylindrical portion 34b. The outer peripheral surface of the scraping member 14 is in close contact with the inner peripheral surface of the lower cylindrical portion 35. The lower surface 14b of the scraping member 14 is received by the bottom wall 33 from below and is in close contact with the bottom wall 33. The inner diameter of the pipe hole 14a is smaller than the outer diameter of the pipe 22. The pipe 22 is press-fitted into the pipe hole 14a, compressing and deforming the pipe hole 14a radially outward, so that the outer periphery of the pipe 22 is in close contact with the inner periphery of the pipe hole 14a. The inner diameter of the bottom hole 33a of the bottom wall 33 is equal to or slightly larger than the outer diameter of the pipe 22. The bottom wall 33 covers the lower surface 14b of the scraping member 14 from below, reducing the contact area of ​​the lower surface 14b with the content liquid L contained in the container body 11.

[0031] The scraping member 14 is firmly held by the projection 33b and the lower end of the second cylindrical portion 34b being pressed vertically against the scraping member 14. The scraping member 14 is housed in the cylindrical portion 32 by fitting the lower cylindrical portion 35 into the second cylindrical portion 34b in a state in which the scraping member 14 is supported by the lower cylindrical portion 35 and the bottom wall 33.

[0032] 1 to 3, the discharge portion 12 is attached to the container body 11 via the attachment cap 23 by inserting the pipe 22 and the pump 20 from above into the cylindrical portion 32 of the inner plug 13, with the container body 11 having the inner plug 13 and the scraping member 14 attached thereto. When the mounting cap 23 is screwed onto the mouth portion 11a, the cylinder 25 is pressed against the upper surface of the fixing portion 31 via the packing 25d by the cap upper wall portion 23b of the mounting cap 23 and fixed thereto. Furthermore, the support tube 30 is prevented from coming off by the peripheral edge of the stem hole 23c of the mounting cap 23 abutting against the outer peripheral flange portion 30b from above. The stem 26 extends upward through a stem hole 23 c in the mounting cap 23 .

[0033] The pipe 22 passes through the pipe hole 14a and the bottom hole 33a of the scraping member 14 to reach the content liquid L below the tubular part 32. The pump 20 is housed in the upper tubular part 34 and is isolated from the content liquid L in the container body 11 by the tubular part 32 and the scraping member 14.

[0034] When the depression head 21 is pressed down, the piston 28 descends and the pressure inside the cylinder body 25a increases, and this pressure causes the content liquid L to be discharged from the discharge port 21a. When the pressing head 21 returns upward due to the biasing force of the biasing member 29, the piston 28 rises and negative pressure is created inside the cylinder main body 25a. Due to this negative pressure, the content liquid L in the container body 11 is sucked up from the lower end 22a of the pipe 22 and sent to the cylinder main body 25a.

[0035] When the pressing head 21 is pressed down to discharge the liquid content L, the pressure inside the container body 11 is reduced by the reduction in the volume of the liquid content L. At this time, air outside the discharge container 10 is introduced into the cylinder 25 from between the stem 26 and the support tube 30, passes through the air hole 25e and flows into the gap 36 between the outer periphery of the cylinder body portion 25a and the inner periphery of the tubular portion 32, and further flows from this gap 36 through the scraping member 14, which is a porous body, into the container body 11. This prevents the container body 11 from being decompressed, and the inside of the container body 11 is kept at an appropriate pressure.

[0036] Figure 4 is a cross-sectional view showing a replacement container 40 for use with the dispensing container 10. In Figure 4, the scraping member 14 is shown in phantom. The replacement container 40 includes the container body 11, the inner plug 13, the scraping member 14, and a cap 41 that closes the mouth portion 11a. That is, the replacement container 40 is the discharge container 10 with the cap 41 attached in place of the discharge portion 12. Although not shown in FIG. 4, the replacement container 40 is filled with the content liquid L.

[0037] The cap 41 comprises an upper wall portion 42 that closes the mouth portion 11a from above, a peripheral wall portion 43 that extends downward from the periphery of the upper wall portion 42 and is attached to the outer periphery of the mouth portion 11a, a plug portion 44 that extends downward from the upper wall portion 42 within the tubular portion 32 of the center plug 13 and closes the upper end of the pipe hole 14a, and an annular cap gasket 45 provided on the underside of the upper wall portion 42.

[0038] The upper wall portion 42 is in the shape of a disk that closes the opening at the upper end of the inside plug 13. In detail, the upper wall portion 42 abuts against the upper surface of the fixing portion 31 of the inside plug 13 via a cap packing 45, thereby closing the mouth portion 11a. An engagement portion 43a that engages with the outer engagement portion 11b of the mouth portion 11a is provided on the inner periphery of the peripheral wall portion 43. The engagement portion 43a is a female thread portion.

[0039] The plug portion 44 includes a cylindrical pillar portion 44a extending downward from the center of the upper wall portion 42, a bottom surface portion 44b closing the bottom surface of the pillar portion 44a, and an annular protruding portion 44c protruding downward from the peripheral edge portion of the bottom surface portion 44b. The plug portion 44 is disposed coaxially with the axis 11c. The protruding portion 44c, which is the lower end of the column portion 44a, fits into the inner circumference of the lower end of the second cylindrical portion 34b of the cylindrical portion 32, and seals the lower end of the cylindrical portion 32. The outer diameter of the protruding portion 44c is equal to or larger than the inner circumference of the lower end of the second cylindrical portion 34b. Therefore, the outer periphery of the protruding portion 44c is in close contact with the inner circumference of the lower end of the second cylindrical portion 34b, and high sealing performance is obtained.

[0040] The cap 41 is fixed to the mouth 11a by screwing the engagement portion 43a of the peripheral wall portion 43 into the outer engagement portion 11b of the mouth 11a. When the cap 41 is fixed to the mouth 11a, the protrusion 44c and the bottom surface portion 44b are pressed against the upper surface of the scraping member 14, thereby blocking the upper end of the pipe hole 14a. In this state, the protrusion 44c compresses the peripheral portion of the pipe hole 14a and bites into the upper surface of the scraping member 14. In FIG. 4, the scraping member 14 is shown in an imaginary line in an undeformed state, but in reality, it is pressed by the cap 41 and deformed. In detail, since the inner diameter of the protruding portion 44c protruding downward in an annular shape is larger than the inner diameter of the pipe hole 14a, the protruding portion 44c bites into the peripheral portion of the pipe hole 14a from above. Then, the peripheral portion of the pipe hole 14a is deformed to follow the inner circumference of the protruding portion 44c and adheres closely to the inner circumference of the protruding portion 44c. As a result, a labyrinth-shaped sealing surface is obtained in which the inner circumference of the protruding portion 44c and the lower surface of the protruding portion 44c adhere closely to the peripheral portion of the pipe hole 14a, and high sealing performance is obtained. Note that the peripheral portion of the pipe hole 14a deformed by the protruding portion 44c may also adhere closely to the lower surface of the bottom surface portion 44b within the protruding portion 44c.

[0041] Here, an example of a procedure for replacing the discharge container 10 with the replacement container 40 will be described. 2 and 3, when the content liquid L of the discharge container 10 is used up, the user releases the screw engagement between the mounting cap 23 and the mouth part 11a, and pulls the discharge part 12 upward to remove the discharge part 12 from the container body 11. When the discharge part 12 is pulled upward, the pipe 22 pressed into the pipe hole 14a of the scraping member 14 is pulled upward in a state of being in close contact with the inner circumference of the pipe hole 14a. At this time, the content liquid L adhering to the outer circumference of the pipe 22 is scraped off by the pipe hole 14a and collected on the lower surface side of the bottom wall 33, and remains in the container body 11. In detail, most of the content liquid L adhering to the outer circumference of the pipe 22 is scraped off by the peripheral part of the pipe hole 14a located on the lower surface 14b of the scraping member 14, and the remaining content liquid L is wiped off by the inner surface of the pipe hole 14a. As a result, when the discharge portion 12 is removed from the container body 11, almost no content liquid L adheres to the outer periphery of the pipe 22, thereby preventing the content liquid L from falling from the outer periphery of the pipe 22 around the discharge portion 12.

[0042] 2, in a state in which the discharge part 12 is attached to the container body 11, the pump 20 is housed in the cylindrical part 32 of the inner plug 13, and is isolated from the content liquid L in the container body 11 by the cylindrical part 32 and the scraping member 14. This prevents the content liquid L from adhering to the outer periphery of the pump 20, and therefore prevents the content liquid L from falling from the outer periphery of the pump 20 to around the discharge part 12 when the discharge part 12 is detached from the container body 11.

[0043] The container body 11 from which the content liquid L has been consumed is discarded, and the discharge part 12 removed from the container body 11 is attached to a replacement container 40 and reused. At this time, the cap 41 is removed from the replacement container 40, and the pipe 22 is inserted into the pipe hole 14a, and the discharge part 12 is attached to the replacement container 40 via the mounting cap 23. Because the lower end 22a of the pipe 22 is tapered, the pipe 22 can be easily inserted into the pipe hole 14a.

[0044] As described above, according to the embodiment to which the present invention is applied, the discharge container 10 includes the container body 11 that stores the content liquid L, and the discharge part 12 that sucks up the content liquid L and discharges it to the outside, and the discharge part 12 includes the mounting cap 23 attached to the cylindrical mouth part 11a of the container body 11, the pump 20 that sucks up the content liquid L, and the pipe 22 that extends downward from the pump 20 to suck up the content liquid L. The discharge container 10 is provided with the inside plug 13 that extends into the container body 11 through the mouth part 11a, and the scraping member 14 supported by the inside plug 13, and the inside plug 13 includes a fixing part 31 fixed to the mouth part 11a and a cylindrical part 32 that extends from the fixing part 31 into the container body 11, the scraping member 14 is stored in the cylindrical part 32 to block the lower part of the cylindrical part 32, and the pump 20 is stored in the cylindrical part 32 above the scraping member 14. When the discharge part 12 is attached to the mouth part 11a, the pipe 22 is pressed into the pipe hole 14a provided in the scraping member 14 and extends into the container body 11, and when the discharge part 12 is removed from the mouth part 11a, the content liquid L adhering to the pipe 22 is scraped off by the pipe hole 14a as the pipe 22 is pulled out from the pipe hole 14a. According to this configuration, since the pump 20 is housed in the cylindrical portion 32, the pump 20 can be isolated from the content liquid L in the container body 11 by the cylindrical portion 32, and adhesion of the content liquid L to the outer surface of the pump 20 can be suppressed. Therefore, when the discharge part 12 is removed from the container body 11, it is possible to suppress the content liquid L from dropping from the pump 20 to the outside of the discharging container 10. Furthermore, when the discharge part 12 is removed from the opening part 11a, the content liquid L adhering to the pipe 22 is scraped off by the pipe hole 14a and drops into the container body 11. Therefore, when the discharge part 12 is removed from the container body 11, it is possible to suppress the content liquid L adhering to the pipe 22 from dropping to the outside of the discharging container 10.

[0045] Moreover, the scraping member 14 is a porous body having closed cells. According to this configuration, the scraping member 14 is a porous material having closed cells, and the content liquid L does not easily pass through the scraping member 14, so that the content liquid L of the container body 11 can be effectively prevented from passing through the scraping member 14 and entering the pump 20 side.

[0046] In addition, the inner plug 13 has a bottom wall 33 that covers the lower surface of the tubular portion 32 and a bottom hole 33a that penetrates the bottom wall 33, the scraping member 14 is supported from below by the bottom wall 33, and the pipe 22 extends into the container body 11 through the pipe hole 14a and the bottom hole 33a. According to this configuration, the scraping member 14 can be firmly supported by the bottom wall 33, and the contact area between the scraping member 14 and the content liquid L of the container body 11 can be reduced, thereby preventing the content liquid L of the container body 11 from passing through the scraping member 14 and entering the pump 20 side.

[0047] Furthermore, the tubular portion 32 comprises an upper tubular portion 34 that houses the pump 20, and a lower tubular portion 35 that is attached to the lower part of the upper tubular portion 34, and the bottom wall 33 is provided on the lower part of the lower tubular portion 35. The lower tubular portion 35 is attached to the upper tubular portion 34 by fitting the second tubular portion 34b, which is the fitting portion at the lower part of the upper tubular portion 34, into the inner circumference of the lower tubular portion 35, and the scraping member 14 is sandwiched between the second tubular portion 34b and the bottom wall 33 in the vertical direction. According to this configuration, by fitting the lower cylindrical portion 35 and the upper cylindrical portion 34 together, the scraping member 14 can be easily fixed by being sandwiched between the second cylindrical portion 34b and the bottom wall 33. In addition, since the scraping member 14 can be firmly supported in the vertical direction by the second cylindrical portion 34b and the bottom wall 33, the pipe 22 can be easily inserted and removed from the pipe hole 14a. Therefore, the pipe 22 can be smoothly pulled out of the pipe hole 14a to efficiently scrape off the content liquid L, and the pipe 22 can be easily pressed into the pipe hole 14a when the discharge part 12 is attached to the mouth part 11a.

[0048] Furthermore, air can flow into the container body 11 through the gap 36 between the outer periphery of the pump 20 and the inner periphery of the cylindrical portion 32, and through the inside of the scraping member 14, which is a porous body. According to this configuration, even in a structure in which the scraping member 14 is provided, air flows into the container body 11 through the gap 36 between the outer periphery of the pump 20 and the inner periphery of the tubular portion 32, and through the scraping member 14, which is a porous body, so that the pressure inside the container body 11 can be adjusted appropriately.

[0049] Further, the lower end 22a of the pipe 22 is formed in a tapered shape tapering toward the lower end. According to this configuration, the lower end 22a is tapered toward the lower end, so that the pipe 22 can be easily inserted into the pipe hole 14a of the scraping member 14. Therefore, the discharge part 12 having the pipe 22 can be easily attached to the container body 11.

[0050] In addition, the replacement container 40 used for the discharge container 10 comprises a container body 11, a mouth portion 11a, an inner plug 13, and a scraping member 14, and the mouth portion 11a is sealed with a cap 41. The cap 41 comprises an upper wall portion 42 that seals the mouth portion 11a from above, a peripheral wall portion 43 that extends downward from the periphery of the upper wall portion 42 and is attached to the outer periphery of the mouth portion 11a, and a plug portion 44 that extends downward from the upper wall portion 42 inside the tubular portion 32 and seals the upper end of the pipe hole 14a. The discharge portion 12 is attached to the mouth portion 11a from which the cap 41 has been removed, via an attachment cap 23. According to this configuration, the mouth 11a and the upper end of the pipe hole 14a of the replacement container 40 can be closed by the cap 41 having the upper wall portion 42 and the plug portion 44 with a simple structure.

For example, the configuration of the above-mentioned embodiment can be appropriately added or deleted, and the configuration of one embodiment can be applied to another embodiment. Furthermore, the effects of the above-mentioned embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above-mentioned effects. In the above embodiment, the lower surface 14b of the scraping member 14 is described as being supported from below by the bottom wall 33 of the inside plug 13, but the present invention is not limited to this. For example, the inside plug 13 may not be provided with the bottom wall 33, and the scraping member 14 may be fixed to the inner circumferential surface of the cylindrical portion 32 by adhesion or the like.
