[0003] [Patent Document 1] JP 2018-023765 A (Figs. 10 to 13) Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional discharge containers, there is room for improvement in terms of ease of replacing the refill container.

[0005] The present invention provides a discharge container that allows easy replacement of a refill container. [Means for solving the problem]

[0006] A dispensing container according to one aspect of the present invention comprises a refill container having a flexible container body in which contents are accommodated and a spout member formed with a communication hole communicating with the inside of the container body; a middle frame member having a connecting tube portion to which the spout member is detachably connected and a connection path communicating with the inside of the container body through the connecting tube portion; a head member attached to the middle frame member, defining a communication space between the middle frame member and the connection path and having a discharge hole formed therein that communicates with the communication space and discharges the contents; a first valve body that switches between communication between the connection path and the communication space and blocking the communication; a second valve body that switches between communication between the discharge hole and the communication space and blocking the communication; and an outer frame member to which the middle frame member is connected via a hinge portion and detachably housed therein, and a head member that operates the head member. As a result, the internal pressure of the communication space increases or decreases, and when the internal pressure of the communication space increases, the first valve body blocks communication between the connection path and the communication space, the second valve body connects the discharge hole and the communication space, and the contents of the communication space are discharged from the discharge hole, and when the internal pressure of the communication space decreases, the second valve body blocks communication between the discharge hole and the communication space, the first valve body connects the connection path and the communication space, and the contents of the connection path are supplied to the communication space and the contents in the container body are supplied to the connection path, and by rotating the middle frame member around the hinge portion, the middle frame member is attached to and detached from the outer frame member, and the middle frame member is provided with a slider to which the mouth member is detachably engaged and which is supported so as to be slidable in the axial direction along the central axis of the connecting tube portion.

[0007] When replacing a refill container with a new one after the contents of the container body have been used up, first, the inner frame member housed in the outer frame member is rotated about the hinge portion and removed from the outer frame member to expose the refill container and slider. Next, the exposed slider is operated to slide it axially toward the opposite side of the connecting tube member to detach the mouth member of the refill container from the connecting tube member. Then, the mouth member is operated to remove it from the slider, and the old refill container is separated from the inner frame member. Next, after the mouth member of the new refill container is engaged with the slider, the slider is slid axially toward the connecting tube portion to connect the mouth member to the connecting tube portion, and the inner frame member is then rotated around the hinge portion to be housed in the outer frame member. As described above, by rotating the middle frame member around the hinge portion, the middle frame member can be attached and detached to and from the outer frame member, and a slider to which the mouth member of the refill container is detachably engaged is provided on the middle frame member.Therefore, by exposing the slider and attaching and detaching the mouth member of the refill container to and from the slider, and sliding the slider in the axial direction, it becomes possible to attach and detach the mouth member of the refill container to and from the connecting tube portion, making it possible to easily replace the refill container and also preventing leakage of the contents inside the container body. With the contents still remaining in the container body, the inner frame member is rotated around the hinge portion to expose the refill container from the outer frame member, allowing the amount of contents remaining in the container body to be easily seen.

[0008] The slider may have a push-in wall portion that covers the bottom of the container body on the side opposite the mouth member along the axial direction, and a push-in protrusion may be provided on the inner surface of the outer frame member that pushes the push-in wall portion toward the connecting tube portion along the axial direction when the middle frame member is accommodated in the outer frame member.

[0009] The slider has a push-in wall portion that covers the bottom of the container body, and a push-in protrusion is provided on the inner surface of the outer frame member, so that when the middle frame member is accommodated in the outer frame member, the push-in wall portion of the slider is pushed toward the connecting tube portion along the axial direction by the push-in protrusion, and the mouth member engaged with the slider is pushed into the connecting tube portion and connected, making it possible to easily replace the refill container.

[0010] When viewed from the axial direction, the central axis is located on the push-in protrusion, and a protrusion is formed on the pushed-in wall portion that protrudes toward the opposite side to the mouth member along the axial direction, and the protrusion may slide over the push-in protrusion when the middle frame member is accommodated in the outer frame member.

[0011] When the inner frame member is housed in the outer frame member, the protrusion of the pressed-in wall slides on the pressing-in protrusion, preventing the slider from shifting position relative to the inner frame member so that the mouth member engaged with the slider is tilted relative to the connecting tubular member. This, combined with the fact that the central axis of the connecting tubular member is located on the pressing-in protrusion when viewed from the axial direction, allows the mouth member to be reliably connected to the connecting tubular member while maintaining a seal between the mouth member and the connecting tubular member.

[0012] The middle frame member has a storage section formed in the shape of a tube with a top, and the refill container and the slider are stored in the storage section, and the slider has a support wall provided between the underside of the top wall of the storage section and the refill container, and the pushed-in wall section extends downward from the support wall and is formed so as to be able to flex and deform in the axial direction around the connection portion with the support wall, and the underside of the top wall of the storage section may have a kick-out protrusion that is positioned on the connecting tube section side along the axial direction and abuts or is close to the upper end of the pushed-in wall section.

[0013] The pushed-in wall is formed to be flexible and deformable in the axial direction around the connection with the support wall, and a kick-out protrusion is provided on the underside of the top wall of the storage section, positioned axially toward the connecting tube section and abutting against or close to the upper end of the pushed-in wall. When the pushed-in wall is flexibly deformed around the connection with the support wall toward the opposite side of the connecting tube section along the axial direction, the upper end of the pushed-in wall pushes the kick-out protrusion of the storage section toward the connecting tube section along the axial direction, causing the slider to move toward the opposite side of the connecting tube section along the axial direction relative to the storage section, and the mouth member of the refill container moves in a direction to detach from the connecting tube section. This allows the mouth member to be easily detached from the connecting tube section, even if the mouth member is tightly connected to the connecting tube section to provide a seal between the mouth member and the connecting tube section.

[0014] The connecting tube portion may be removably fitted into the communicating hole, and a sealing plug that was removably fitted into the communicating hole may be housed inside the container body, and is pushed in the axial direction by the connecting tube portion and removed from the communicating hole.

[0015] When connecting the mouth member of a new refill container to the connecting tube portion, a sealing plug is removably fitted into the communicating hole to seal the inside of the container body, and when the slider is pushed axially toward the connecting tube portion, the connecting tube portion pushes the sealing plug axially, causing it to separate from the communicating hole and move into the container body, thereby reliably preventing the contents in the container body from leaking when replacing it with a new refill container. When the slider has a push-in wall portion and a push-in protrusion is provided on the inner surface of the outer frame member, by accommodating the middle frame member in the outer frame member, when the push-in wall portion of the slider is pushed axially toward the connecting tube portion by the push-in protrusion of the outer frame member, the connecting tube portion pushes the sealing plug axially, causing it to separate from the communicating hole and move into the container body.

[0016] The head member may have a top wall whose front and back surfaces face in the vertical direction, the discharge hole formed in the top wall, the central axis of the connecting tube portion extending in a horizontal direction intersecting the vertical direction, and the communication space extending downward from the underside of the top wall and arranged side by side with the connecting tube portion and the refill container in a horizontal direction intersecting the vertical direction.

[0017] The central axis of the connecting tube portion extends in a horizontal direction intersecting the vertical direction, and the communication space extends downward from the underside of the top wall and is arranged side by side with the connecting tube portion and the refill container in a horizontal direction intersecting the vertical direction, so that a flat compact container with a low vertical height can be obtained. [Effects of the Invention]

[0018] According to the above aspect of the present invention, the refill container can be easily replaced. [Brief explanation of the drawings]

[0020] Hereinafter, a discharge container according to a first embodiment will be described with reference to the drawings. 1, the discharge container 1 according to this embodiment includes a refill container 11, an inner frame member 12, a head member 13, a first valve body 14, a second valve body 15, and an outer frame member 16. All of the components of the discharge container 1 are made of synthetic resin, except for the biasing member 40 described below.

[0021] The outer frame member 16 is formed in a cylindrical shape with a bottom. The side of the bottom wall 16a of the outer frame member 16 that is along the central axis of the outer frame member 16 (hereinafter referred to as the first axis O1) is referred to as the lower side, and the opposite side is referred to as the upper side. The direction along the first axis O1 is referred to as the up-down direction. 2 and 3, a lid 17 is connected to the outer frame member 16 so as to be rotatable about a first rotation axis L1. The first rotation axis L1 extends in a horizontal direction perpendicular to the up-down direction. The lid 17 opens and closes the upper end opening of the outer frame member 16 by rotating up and down about the first rotation axis L1.

[0022] The inner frame member 12 is detachably housed within the outer frame member 16. The inner frame member 12 includes an inner frame main body 20 and an auxiliary inner frame 24. The inner frame main body 20 and the auxiliary inner frame 24 may be integrally formed. The middle frame body 20 is connected to the outer frame member 16 via hinge portions 18 and is rotatable about a second rotation axis L2. The second rotation axis L2 is located above the first rotation axis L1 and extends parallel to the first rotation axis L1 when viewed from the top-bottom direction. By rotating the middle frame body 20 about the hinge portions 18, the middle frame member 12 is attached to and detached from the outer frame member 16. The middle frame body 20 is configured by a first storage section 21 formed in a cylindrical shape with a bottom and a second storage section 22 formed in a cylindrical shape with a top, which are arranged in parallel with each other and share a portion of their peripheral walls.

[0023] Hereinafter, the common peripheral wall of the first storage section 21 and the second storage section 22 will be referred to as a partition wall 19. When viewed from the top-bottom direction, the side where the first storage section 21 is located relative to the partition wall 19 is referred to as the front side, and the side where the second storage section 22 is located relative to the partition wall 19 is referred to as the rear side. When viewed from the top-bottom direction, the direction perpendicular to the front-to-back direction is referred to as the left-to-right direction.

[0024] An upwardly extending mounting tube 21b is formed on the bottom wall 21a of the first storage section 21. The rear end of the mounting tube 21b is connected to the partition wall 19 in the front-to-rear direction via a connecting portion 21c. A first through-hole 21d is formed in the mounting tube 21b, the connecting portion 21c, and the partition wall 19, penetrating them integrally in the front-to-rear direction.

[0025] A connecting tube portion 25 is formed on the rear surface of the partition wall 19 at the periphery of the opening of the first through-hole 21d, protruding toward the inside of the second accommodating portion 22 at the rear. Hereinafter, the central axis of the connecting tube portion 25 extending in the front-to-rear direction, which is one of the horizontal directions intersecting the up-down direction, will be referred to as the second axis O2, the direction intersecting the second axis O2 when viewed from the front-to-rear direction will be referred to as the radial direction, and the direction circumferentially around the second axis O2 when viewed from the front-to-rear direction will be referred to as the circumferential direction. A step 25a extending radially outward toward the front is formed on the outer peripheral surface of the connecting cylindrical portion 25. The step 25a is provided in the middle of the outer peripheral surface of the connecting cylindrical portion 25 in the front-rear direction.

[0026] An auxiliary inner frame 24 is provided inside the first storage section 21. The auxiliary middle frame 24 includes an outer tube 31, an inner tube 32, and a bottom wall 33, and is formed into a cylindrical shape with a bottom. The outer tube 31 is fitted and fixed inside the mounting tube 21b. The outer tube 31 closes the front end opening of the first through hole 21d. Note that the outer tube 31 may leave the front end opening of the first through hole 21d open, in which case the recessed groove 31a, described below, does not need to be formed on the outer peripheral surface of the outer tube 31. An annular piston 35 is fitted into the inner cylinder 32 so as to be able to slide up and down. A lower end of a biasing member 40 extending in the vertical direction is supported on the upper surface side of the bottom wall 33 in a portion located between the inner peripheral surface of the outer cylinder 31 and the outer peripheral surface of the inner cylinder 32. The biasing member 40 is a metal coil spring. The biasing member 40 may also be made of synthetic resin.

[0027] A vertical gap X is provided between the lower surface of the bottom wall 33 and the upper surface of the bottom wall 21a of the first housing portion 21. A recessed groove 31a is formed in the outer peripheral surface of the outer tube 31, connecting the front end opening of the first through-hole 21d and the gap X in the vertical direction. A second through-hole 33a is formed in the bottom wall 33, penetrating the wall in the vertical direction and opening into the inner tube 32.

[0028] The second through-hole 33a, the gap X, the recessed groove 31a, and the first through-hole 21d form a connection path 34 that connects the interior of the inner cylinder 32 with the interior of the connecting cylinder portion 25.

[0029] The head member 13 is attached to the inner frame member 12, and defines a communication space Y between the head member 13 and the auxiliary inner frame 24, which communicates with the connection path 34. The head member 13 is formed with a discharge hole 26 which communicates with the communication space Y and discharges the contents. The head member 13 has a top wall 27 whose front and back surfaces face up and down. The top wall 27 is located above the mounting tube 21b and is inserted into the peripheral wall of the first housing portion 21 so as to be slidable up and down. The upper end of the biasing member 40 is supported on the lower surface of the top wall 27. A push-down tube 27a is formed on the lower surface of the top wall 27, extending downward and inserted into the inner tube 32 of the auxiliary inner frame 24. The lower open edge of the push-down tube 27a faces the upper surface of the piston 35 in the up and down direction while being spaced apart from it. When the head member 13 is pressed down, the lower open edge of the push-down tube 27a presses down on the upper surface of the piston 35. The head member 13 is provided with a piston guide 13a that penetrates the inside of the piston 35 in the up and down direction. As the head member 13 moves downward and rises, the piston guide 13a engages with the piston 35, causing the piston 35 to rise. A discharge hole 26 is formed in the top wall 27. The discharge hole 26 opens toward the inside of the push-down cylinder 27a.

[0030] The communication space Y is a portion within the inner tube 32 of the auxiliary inner frame 24 where the internal pressure increases or decreases by operating the head member 13. In the illustrated example, the communication space Y is a portion within the inner tube 32 where the internal pressure increases or decreases in accordance with the up and down movement of the head member 13 and the piston 35. The communication space Y extends downward from the underside of the top wall 27 of the head member 13. A connecting passage 34 communicates with the lower end of the communication space Y. The communication space Y is arranged in line with the connecting tube portion 25 and the refill container 11 in the front-to-rear direction (the horizontal direction intersecting the up-and-down direction).

[0031] The first valve body 14 is provided on the upper surface of the bottom wall 33 inside the inner cylinder 32 and opens and closes the second through-hole 33a. The first valve body 14 switches between connecting and blocking communication between the connection path 34 and the communication space Y. The first valve body 14 is a check valve that allows the contents in the connection path 34 to flow into the communication space Y and prevents flow in the reverse direction. In the example shown, the first valve body 14 is a so-called three-point valve that includes an annular fixed part fitted inside the inner cylinder 32, a plate-shaped valve body that is provided inside the fixed part and opens and closes the second through-hole 33a, and multiple elastic pieces that connect the inner circumferential surface of the fixed part to the outer circumferential surface of the valve body. The second valve body 15 is provided on the top wall 27 of the head member 13 and opens and closes the discharge hole 26. The second valve body 15 switches between connecting and blocking communication between the discharge hole 26 and the communication space Y. The second valve body 15 is a check valve that allows the contents of the communication space Y to flow out onto the top wall 27 and prevents flow in the opposite direction. In the example shown, the second valve body 15 comprises a shaft that extends in the vertical direction and a valve body that is formed in an umbrella shape that protrudes radially outward from the upper end of the shaft and is formed to be elastically deformable in the vertical direction; the shaft is inserted into and fixed in the discharge hole 26, and the discharge hole 26 is opened and closed by elastic deformation of the valve body.

[0032] When the head member 13 is pressed down against the biasing force of the biasing member 40 and the piston 35 is lowered, the internal pressure of the communication space Y increases, causing the first valve body 14 to block communication between the connection path 34 and the communication space Y, and the second valve body 15 to connect the discharge hole 26 to the communication space Y, causing the contents of the communication space Y to be discharged from the discharge hole 26. Thereafter, when the head member 13 is released from the pressure, the restoring force of the urging member 40 causes the head member 13 and the piston 35 to move upward in their original position, and the internal pressure of the communication space Y decreases, causing the second valve body 15 to block communication between the discharge hole 26 and the communication space Y, and the first valve body 14 to connect the connection path 34 to the communication space Y, so that the contents of the connection path 34 are supplied to the communication space Y, and the contents in the container body 41 of the refill container 11, which will be described later, are supplied to the connection path 34.

[0033] The refill container 11 includes a container body 41, a mouth member 42, and a sealing plug 43, and is housed in the second housing portion 22. The contents are accommodated in the container body 41. The container body 41 is made of, for example, a laminated film or a thin-walled resin molded product, and is flexible. The container body 41 undergoes volume reduction and deformation as the contents are dispensed. The mouth member 42 is detachably connected to the connecting tubular portion 25 of the inner frame member 12. A communication hole 44 that communicates with the inside of the container body 41 is formed in the mouth member 42. The connecting tubular portion 25 is detachably fitted into the communication hole 44. The inside of the container body 41 and the connection passage 34 are in communication through the connecting tubular portion 25. In the illustrated example, a step portion 44a is formed on the inner circumferential surface of the communication hole 44, extending radially outward as it moves forward. The step portion 44a is provided in the middle portion in the front-to-rear direction on the inner circumferential surface of the communication hole 44. This step portion 44a abuts liquid-tightly against the step portion 25a of the connecting tubular portion 25 in the front-to-rear direction. 1, the sealing plug 43 is fitted into the communicating hole 44 to seal the inside of the container body 41. When the refill container 11 is attached to the inner frame member 12, the sealing plug 43 is pushed rearward by the connecting tube portion 25, removed from the communicating hole 44, and moved into the container body 41 to be accommodated.

[0034] The slider 45 is provided on the inner frame member 12. The slider 45 is detachably engaged with the mouth member 42 and is supported so as to be slidable in the front-rear direction. The slider 45 is accommodated in the second accommodating portion 22. Here, an opening 22a that penetrates the entire peripheral wall of the second housing portion 22 in the front-to-rear direction is formed in a portion that faces the partition wall 19. As shown in Figures 4 and 5, when the slider 45 slides rearward, the rear portion of the slider 45 protrudes rearward from the second housing portion 22 through the opening 22a.

[0035] 2, the slider 45 includes a support wall 46 provided between the underside of the top wall of the second storage portion 22 and the refill container 11, and side walls 47 protruding downward from both left and right ends of the support wall 46. The support wall 46 is formed in a plate shape with its front and back surfaces facing up and down, and the side walls 47 are formed in a plate shape with its front and back surfaces facing left and right. The upper surface of the support wall 46 abuts against or is close to the underside of the top wall of the second storage portion 22, and the outer surfaces of the side walls 47 abut against or are close to the inner surfaces of the peripheral walls of the second storage portion 22.

[0036] A restricting protrusion 47a is formed on the outer surface of the side wall 47, and a restricting hole 22b into which the restricting protrusion 47a is fitted so as to be movable in the front-rear direction is formed on the inner surface of the peripheral wall of the second accommodating portion 22. The restricting hole 22b penetrates the peripheral wall of the second accommodating portion 22 in the left-right direction. The rear end of the restricting hole 22b is closed and does not open rearward, and further rearward movement of the slider 45 is restricted by the restricting protrusion 47a abutting against the rear end surface of the inner surface of the restricting hole 22b. The restriction hole 22b may be a groove that does not penetrate in the left-right direction, or the restriction protrusion 47a may be formed on the peripheral wall of the second accommodating portion 22, and the restriction hole 22b may be formed on the side wall 47.

[0037] The slider 45 has a pressed wall portion 38 that covers the bottom portion 41a located at the rear end of the container body 41. A plurality of pressed wall portions 38 are provided at intervals in the left-right direction. The pressed wall portions 38 protrude downward from the rear end of the support wall 46 of the slider 45. The lower end of the pressed wall portion 38 curves so as to extend forward as it extends downward. The lower end of the pressed wall portion 38 and the rear end of the support wall 46 face each other, sandwiching the bottom portion 41a of the container body 41 in the vertical direction.

[0038] A pushing protrusion 39 is provided on the inner surface of the outer frame member 16. The pushing protrusion 39 pushes the pushed-in wall portion 38 of the slider 45 forward when the middle frame member 12 is housed in the outer frame member 16. The pushing protrusion 39 is formed on the rear end surface of the inner surface of the outer frame member 16. In the illustrated example, a protrusion 38a that protrudes rearward is formed on the pushed-in wall portion 38, and when the middle frame member 12 is housed in the outer frame member 16, first, the portion of the pushed-in wall portion 38 that is located below the protrusion 38a slides over the pushing protrusion 39, and then the protrusion 38a slides over the pushing protrusion 39. It is noted that the pushed-in wall portion 38 does not necessarily have to have the protrusion 38a formed thereon.

[0039] Here, the mouth member 42 of the refill container 11 includes a cylindrical mouth portion 48 that extends in the front-rear direction and has a communicating hole 44 on the inside, and a flat flange-shaped first locking plate portion 51 that protrudes radially outward from the cylindrical mouth portion 48. Two first locking plates 51 are provided spaced apart in the front-rear direction. Each first locking plate portion 51 is formed in a plate shape with its front and back surfaces facing the front-rear direction. When viewed from the front-rear direction, the first locking plate portion 51 has an oval shape or a rectangular shape that is long in the left-right direction. The first locking plate portion 51 protrudes radially outward along the entire circumference from the outer circumferential surface of the cylindrical mouth portion 48.

[0040] A second locking plate 52 and a third locking plate 53 are formed at the front end of the support wall 46 of the slider 45, protruding downward. The second locking plate 52 and the third locking plate 53 are formed in the shape of a plate with the front and back surfaces facing the front-rear direction. The second locking plate 52 and the third locking plate 53 are inserted between the first locking plates 51 that are adjacent to each other in the front-rear direction. Two second locking plates 52 are provided at a distance in the left-right direction. As shown in Fig. 2, the two second locking plates 52 sandwich the nozzle portion 48 in the left-right direction. The third locking plate portions 53 are provided between the second locking plate portions 52 adjacent to each other in the left-right direction, and are in contact with or close to the upper end of the outer circumferential surface of the nozzle portion 48.

[0041] Next, a method for replacing the refill container 11 after the contents of the container body 41 have been used up with a new refill container 11 will be described.

[0042] First, as shown in Fig. 3, the lid body 17 is rotated upward about the first rotation axis L1 relative to the outer frame member 16 and the inner frame member 12 to open the top of the inner frame member 12, and then the inner frame member 12 is rotated upward about the hinge portion 18 relative to the outer frame member 16 to remove the inner frame member 12 from the outer frame member 16 and expose the refill container 11 and the slider 45. At this time, as shown in Figs. 3 to 5, the inner frame member 12, the refill container 11, and the slider 45 are in an upside-down position.

[0043] Next, the exposed slider 45 is operated to slide rearward relative to the inner frame member 12 as shown in Fig. 5, causing the second locking plate portion 52 and the third locking plate portion 53 of the slider 45 to abut against the first locking plate portion 51 of the mouth member 42, thereby moving the refill container 11 rearward and releasing the mouth member 42 from the connecting tube portion 25. Then, as shown in Fig. 4, when the mouth member 42 is operated and pulled up, the refill container 11 rotates around the bottom portion 41a of the container body 41, which is sandwiched vertically between the lower end of the pressed-in wall portion 38 and the rear end of the support wall 46, causing the first locking plate portion 51 to move upward away from the second locking plate portion 52 and the third locking plate portion 53. This allows the refill container 11 to be released from the slider 45 and separated from the inner frame member 12.

[0044] Next, as shown in Fig. 4, the bottom 41a of the new refill container 11 is inserted between the lower end of the pushed-in wall 38 and the rear end of the support wall 46, and in a state where it is abutted against the front of the pushed-in wall 38, the refill container 11 is rotated around the bottom 41a toward the support wall 46, as shown in Fig. 5, and the second locking plate 52 and the third locking plate 53 of the slider 45 are inserted between the first locking plates 51 adjacent to each other in the front-to-rear direction. At this time, the two second locking plates 52 sandwich the nozzle 48 of the refill container 11 in the left-to-right direction, and the third locking plate 53 abuts against or comes close to the outer circumferential surface of the nozzle 48, thereby locking the nozzle member 42 of the refill container 11 to the slider 45. Here, in the new refill container 11, the sealing plug 43 is fitted into the communication hole 44 to seal the inside of the container body 41.

[0045] 6, the slider 45 is slid forward to insert the connecting tube portion 25 of the inner frame member 12 into the communicating hole 44 of the refill container 11. At this time, the step portion 44a of the communicating hole 44 does not reach the step portion 25a of the connecting tube portion 25, but is separated rearward, so that the sealing plug 43 remains fitted in the communicating hole 44. Next, the inner frame member 12 is rotated around the hinge portion 18 and housed in the outer frame member 16. During this process, the pushed-in wall portion 38 of the slider 45 slides on the pushing protrusion 39 of the outer frame member 16, causing the slider 45 to move forward together with the refill container 11, and the connecting tube portion 25 of the inner frame member 12 enters and fits into the communicating hole 44 of the refill container 11. At this time, as shown in FIG. 1 , the step portion 44a of the communicating hole 44 reaches and liquid-tightly abuts the step portion 25a of the connecting tube portion 25, and the sealing plug 43 of the refill container 11 is pushed rearward by the rear end opening edge of the connecting tube portion 25 and is released from the communicating hole 44, and the sealing plug 43 is housed in the container body 41. Here, since the lower end of the rear surface of the pushed-in wall portion 38 extends forward as it goes downward, when the lower end of the rear surface of the pushed-in wall portion 38 hits the upper end of the push-in protrusion 39 of the outer frame member 16, as shown in Figure 6, it is easy to move the slider 45 forward.

[0046] As described above, according to the discharge container 1 of this embodiment, by rotating the middle frame member 12 around the hinge portion 18, the middle frame member 12 can be attached to and detached from the outer frame member 16, and the middle frame member 12 is provided with a slider 45 to which the mouth member 42 of the refill container 11 is detachably engaged.Therefore, with the slider 45 exposed, the mouth member 42 of the refill container 11 can be attached and detached to and from the slider 45, and by sliding the slider 45 in the forward and backward directions, the mouth member 42 of the refill container 11 can be attached and detached to the connecting tube portion 25, which makes it possible to easily replace the refill container 11 and also to prevent leakage of the contents in the container body 41.

[0047] With the contents still remaining in the container body 41, the inner frame member 12 is rotated around the hinge part 18 to expose the refill container 11 from the outer frame member 16 for visual confirmation, whereby the remaining amount of the contents in the container body 41 can be easily visually confirmed.

[0048] The slider 45 has a pushed-in wall portion 38 that covers the bottom 41a of the container body 41, and a push-in protrusion 39 is provided on the inner surface of the outer frame member 16, so that when the middle frame member 12 is accommodated in the outer frame member 16, the pushed-in wall portion 38 of the slider 45 is pushed forward by the push-in protrusion 39, and the mouth member 42 engaged with the slider 45 is pushed into and connected to the connecting tube portion 25, making it possible to easily replace the refill container 11.

[0049] When connecting the mouth member 42 of a new refill container 11 to the connecting tube portion 25, the sealing plug 43 is fitted into the communicating hole 44 to seal the inside of the container body 41, and when the inner frame member 12 is housed in the outer frame member 16 and the pushed-in wall portion 38 of the slider 45 is pushed forward by the pushing protrusion 39 of the outer frame member 16, the connecting tube portion 25 pushes the sealing plug 43 rearward, removing it from the communicating hole 44 and moving it into the container body 41, thereby reliably preventing the contents in the container body 41 from leaking when replacing it with a new refill container 11.

[0050] The second axis O2, which is the central axis of the connecting tube portion 25, extends in a horizontal direction intersecting the vertical direction, and the communication space Y extends downward from the underside of the top wall 27 and is arranged side by side with the connecting tube portion 25 and the refill container 11 in a horizontal direction intersecting the vertical direction, so that a flat compact container with a low vertical height can be obtained.

[0051] As shown in Figure 4, the bottom 41a of the new refill container 11 is inserted between the lower end of the pushed-in wall portion 38 and the rear end of the support wall 46, and when it is abutted against the front of the pushed-in wall portion 38, the refill container 11 is rotated around the bottom 41a toward the support wall 46. As shown in Figure 5, the second locking plate portion 52 and the third locking plate portion 53 of the slider 45 are inserted between the first locking plate portions 51 that are adjacent to each other in the front-to-back direction, and the mouth member 42 of the refill container 11 is locked to the slider 45. Therefore, when setting the refill container 11 on the slider 45, there is no need to accurately determine the relative positions of the refill container 11 and the slider 45, and the refill container 11 can be easily replaced.

[0052] Next, a discharge container 2 according to a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted, with only the differences being described.

[0053] In the discharge container 2 of this embodiment, the second axis O2, which is the central axis of the connecting tube portion 25 when viewed from the front-rear direction, is located on the push-in protrusion 39. The second axis O2 passes through the vertical center of the push-in protrusion 39 in the front-rear direction. The left-right center of the push-in protrusion 39 and the protrusion 38a coincide with each other. The protrusion 38a is located above the second axis O2. The three pressed wall portions 38 are provided across the entire left-right area of ​​the second housing portion 22, with three walls spaced apart in the left-right direction. The left-right dimensions of the pressed wall portions 38 are the same. Of the three pressed wall portions 38, the lower end of the pressed wall portion located in the center in the left-right direction (hereinafter referred to as the inner pressed wall portion 61) is located lower than the lower ends of the other two pressed wall portions 38 and curves forward as it extends downward. The lower end of the inner pressed wall portion 61 abuts against or is close to the upper surface of the bottom wall 16a of the outer frame member 16. The other two pressed wall portions 38 extend straight in the up-down direction across the entire area. The other two pressed wall portions 38 are spaced upward from the upper surface of the bottom wall 16a of the outer frame member 16.

[0054] As shown by the two-dot chain line in Figure 8, when the inner frame member 12 is housed in the outer frame member 16, the inner pushed-in wall portion 61 of the slider 45 first comes into contact with the push-in protrusion 39. In the example shown, when the inner frame member 12 is rotated around the hinge portion 18 relative to the outer frame member 16 and housed therein, the lower end of the inner pushed-in wall portion 61 of the slider 45 first comes into contact with the upper end of the push-in protrusion 39. Thereafter, the protrusion 38a of the inner pushed-in wall portion 61 slides over the push-in protrusion 39.

[0055] The inner push-in wall portion 61 is formed so as to be able to flex and deform in the front-rear direction around the connection portion with the support wall 46. In the illustrated example, a third through hole 46a is formed in the rear end portion of the support wall 46 in a portion adjacent to the inner push-in wall portion 61 in the front-rear direction. The left-right sizes of the third through hole 46a and the inner push-in wall portion 61 are equal to each other. It is not necessary to form the third through hole 46a in the support wall 46. A kicked-out protrusion 22c is provided on the underside of the top wall of the second accommodating section 22, and is located forward of and abuts against or is close to the upper end of the inner pushed-in wall section 61. The kicked-out protrusion 22c extends in the front-to-rear direction, and the rear end face of the kicked-out protrusion 22c abuts against or is close to the front face of the upper end of the inner pushed-in wall section 61. A restricting portion 2a is provided between the upper surface of the support wall 46 of the slider 45 and the lower surface of the top wall of the second housing portion 22 to restrict relative movement in the left-right direction between the slider 45 and the second housing portion 22. The restricting portion 2a is composed of a groove extending in the front-rear direction and a protrusion housed in this groove so as to be movable back and forth. A plurality of restricting portions 2a are provided at intervals in the left-right direction.

[0056] As described above, according to the discharge container 2 of this embodiment, when the inner frame member 12 is housed in the outer frame member 16, the inner pushed-in wall portion 61 of the slider 45 first comes into contact with the push-in protrusion 39, so when the inner frame member 12 is housed in the outer frame member 16, the inner pushed-in wall portion 61 is pushed forward by the push-in protrusion 39 from the beginning, and it is possible to prevent the slider 45 from shifting position relative to the inner frame member 12 so that the spout member 42 engaged with the slider 45 is tilted relative to the connecting tubular portion 25. This, combined with the fact that the second axis O2, which is the central axis of the connecting tubular portion 25, is located on the push-in protrusion 39 when viewed from the front-to-rear direction, makes it possible to reliably connect the spout member 42 to the connecting tubular portion 25 while maintaining a seal between them.

[0057] The inner pushed-in wall portion 61 is formed to be able to flex and deform in the front-to-rear direction around the connection portion with the support wall 46, and the lower surface of the top wall of the second storage portion 22 is provided with a kick-out protrusion 22c located forward and abutting or close to the upper end portion of the inner pushed-in wall portion 61. Therefore, when the inner pushed-in wall portion 61 is flexibly deformed rearward around the connection portion with the support wall 46, the upper end portion of the inner pushed-in wall portion 61 pushes the kick-out protrusion 22c of the second storage portion 22 forward, causing the slider 45 to move rearward relative to the second storage portion 22, and the mouth member 42 of the refill container 11 to move in a direction to detach from the connecting tube portion 25. At this time, in the illustrated example, the step 44a of the communication hole 44 of the mouth member 42 moves rearward away from the step 25a of the connecting tube portion 25. This provides sealing between the mouth member 42 and the connecting tubular portion 25, so that even if the mouth member 42 is tightly connected to the connecting tubular portion 25, the mouth member 42 can be easily detached from the connecting tubular portion 25.

[0058] 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.

[0059] In the above embodiment, the discharge holes 26 are formed in the top wall 27 and open upward, but the discharge holes 26 may be opened in, for example, a radial direction. The slider 45 may not have the pushed-in wall portion 38, and the outer frame member 16 may not be provided with the pushing protrusion 39. In this case, for example, before the inner frame member 12 is housed in the outer frame member 16, the mouth member 42 of a new refill container 11 may be connected to the connecting tube portion 25, and the sealing plug 43 may be pushed rearward by the connecting tube portion 25 to remove it from the communicating hole 44 and move it into the container body 41. The second axis O2, which is the central axis of the connecting tubular portion 25, is not limited to extending in the front-rear direction, but may also extend, for example, in the up-down direction. The communication space Y may be arranged, for example, vertically alongside the connecting tube portion 25 and the refill container 11. The hinge portion 18 may be located on the opposite side of the first rotation axis L1, with the central axis O1 sandwiched in the radial direction, or may connect the front and rear ends of the inner frame main body 20 and the outer frame member 16 to each other.

[0060] 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.
