JP2011-251695A

  However, the conventional discharge container is provided with an air valve that switches between communication between the intake hole and the outside and switching between the intake hole and the outside, and there is room for improvement in reducing the number of parts.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to reduce the number of parts.

In order to solve the above problems, the present invention proposes the following means.
The discharge container according to the present invention includes an inner container that accommodates the contents and is volume-reduced and deformed as the contents are reduced, and the inner container includes an intake hole that sucks outside air between the inner container and the inner container. A container body having an elastically deformable outer container formed, and a top cylindrical discharge body in which a discharge hole for discharging the contents in the inner container is formed in the top wall, and the container body And a covering member that covers the discharge hole is disposed on the top surface of the top wall, and the covering member is arranged around the central axis of the discharge hole. And a non-fixed portion located inside the fixed portion of the covering body is fixed to the upper surface of the top wall portion through a fixed portion having an opening in the circumferential direction. The discharge hole is sealed to the top surface of the top wall portion so as to be separable. The discharge cap is formed with an introduction pore that communicates the intake hole and the outside, and the introduction pore serves as an air between the outer container and the inner container during squeeze deformation of the outer container. While the squeeze deformation of the outer container is released, outside air is caused to flow toward the intake hole.

  According to the present invention, since the non-fixed portion of the covering seals the discharge hole in the unused state, the sealing of the inner container can be ensured, and the contents can flow out of the discharge hole unexpectedly. Leakage to the outside can be suppressed.

  Next, when discharging the contents, squeeze the outer container and push it inward in the radial direction to press the container body, thereby increasing the internal pressure of the inner container and discharging the contents. Can flow out of the hole. Then, the cover is pressed by the contents flowing out from the discharge hole, and the non-fixed portion of the cover is separated from the upper surface of the top wall and swells into a dome shape that protrudes upward. As a result, a flow channel communicating with the discharge hole is defined between the covering and the top wall portion, and a flow channel port opened outward at the opening portion of the fixing portion is defined. Therefore, the contents flowing out from the discharge holes can be discharged to the outside from the flow path port through the flow path.

After that, stopping or releasing the pressing of the container body to stop the outflow of the contents from the discharge hole, the pressing force from the contents applied to the covering is released, and the top wall part The non-fixed portion of the covering that has been separated from the upper surface is restored to its original state and is in close contact with the upper surface of the top wall portion. As a result, the channel opening and the channel are closed and the discharge hole is sealed, so that the sealing of the inner container can be ensured again.
Here, when the squeeze deformation of the container body is released and a negative pressure is generated between the inner container and the outer container, the outside air is sucked into the inner container and the outer container from the intake hole through the introduction pore. As a result, a gap space is defined between the inner container and the outer container, or the already formed gap space is enlarged. Therefore, the outer container can be smoothly restored and deformed while reducing the volume of the inner container.

  By the way, when the outer container is squeezed and deformed in order to discharge the contents in a state where a gap space is defined between the inner container and the outer container, the outflow of air between the outer container and the inner container is prevented. It is regulated by the introduction pore. Therefore, the pressing force acting on the outer container can be efficiently applied to the inner container via the gap space, and the inner pressure of the inner container can be reliably increased.

  As described above, according to this discharge container, instead of providing the air valve as in the prior art, by providing the introduction pores, it is possible to suppress air leakage during squeeze deformation of the outer container, while the outer container It becomes possible to introduce air at the time of restoration deformation, and the number of parts can be reduced.

  The introduction pore may be formed in a groove shape.

  In this case, since the introduction pore is formed in a groove shape, the introduction pore can be formed on the outer surface of the discharge cap while ensuring the flow path length. Thereby, the outflow of the air between an outer container and an inner container can be suppressed effectively at the time of squeeze deformation of an outer container.

  Of the introduction pores, the opening area of the inner end portion on the intake hole side may be minimized.

  In this case, since the opening area of the inner end portion on the intake hole side is the smallest among the introduction pores, the outflow of air between the outer container and the inner container is introduced during the squeeze deformation of the outer container. Can be surely suppressed.

  According to the present invention, the number of parts can be reduced.

The communication between the intake hole 12 and the outside of the discharge container 1 is blocked.
A connecting wall 32 projects upward from a portion of the upper end portion of the exterior portion 30 located on the rear side. The connecting wall 32 is formed in an arc shape in plan view, and the hinge portion 4 for connecting the hinge cap 5 so as to be openable and closable is formed on the outer peripheral surface on the upper end side.

  As shown in FIGS. 1 to 3, a stepped portion 33 is formed on the outer peripheral surface on the upper end side of the exterior portion 30. The stepped portion 33 is fitted to the lower end portion of the hinge cap 5 except the portion where the connecting wall 32 is formed. Has been. In addition, the upper end portion of the exterior portion 30 and the inner peripheral surface of the connecting wall 32 are provided so as to project radially inward and are disposed on the outer flange portion 22 of the interior portion 20 and the inner flange portion 24. An annular top wall 34 covering the upper side is provided continuously. The top wall portion 34 is continuously provided with a mounting cylinder portion 35 projecting upward from the inner peripheral edge portion, and the mounting cylinder portion 35 is in a radial direction with respect to the guide cylinder portion 25 of the interior portion 20. It touches from the outside.

The mounting cylinder portion 35 has a different height in the circumferential direction. In the illustrated example, the portion located on the rear side is the lowest, and the other portion projects upward from the portion located on the rear side. Specifically, the height of the portion located on the rear side of the mounting cylinder portion 35 is substantially the same as the height of the guide cylinder portion 25 of the interior portion 20, and the heights of the other portions of the mounting cylinder portion 35 are , Projecting upward from the guide tube portion 25.
A concave rib-shaped vertical groove 35 a is formed on the inner peripheral surface of the mounting cylinder portion 35 located on the rear side. The vertical groove 35a communicates with an internal space E1 (annular space) defined by the top wall portion 34 of the exterior portion 30, the inner flange portion 24 of the interior portion 20, and the like. On the other hand, first convex ribs 35b are projected from the mounting cylinder portion 35 other than the portion located on the rear side toward the outer side in the radial direction.

  The discharge body 40 is a top tube-shaped member that is moved up and down in accordance with the opening / closing operation of the hinge cap 5, and is a discharge cylinder fitted inside the guide tube portion 25 of the interior portion 20 so as to be slidable up and down. Part 41, a top wall part 42 that is connected to the upper end part of discharge cylinder part 41 and closes the upper opening of discharge cylinder part 41, and a flange that protrudes radially outward from discharge cylinder part 41 Part 43 and extending downward from the outer peripheral edge of the flange part 43, and surrounding the mounting cylinder part 35 of the exterior part 30 from the outside in the radial direction so as to be slidable vertically on the mounting cylinder part 35 The fitting cylinder part 44 was provided.

The top wall portion 42 protrudes outward in the radial direction over the entire circumference of the discharge cylinder portion 41, is substantially D-shaped in a plan view, and is formed in a concave curved surface shape. Inclined. Specifically, the ceiling wall portion 42 is inclined upward so that the front side is located above the rear side where the hinge portion 4 is located.
In addition, the discharge body 40 is mounted in a state in which the discharge body 40 is positioned in the circumferential direction with respect to the exterior portion 30, and the hinge portion formed on the exterior portion 30 with the front portion 42 a side of the top wall portion 42 sandwiching the container shaft O. It is positioned so as to face the side opposite to 4.

  The front portion 42a side of the top wall portion 42 has an outer shape extending substantially in parallel along the front-rear direction and the left-right direction orthogonal to the container axis O. On the other hand, the rear part 42b side of the top wall part 42 is formed in a semicircular shape in plan view. As a result, the entire top wall portion 42 is formed in a substantially D shape in plan view as described above.

Further, the top wall portion 42 gradually rises from the center to the outside along the left-right direction, and is curved into a vertical cross-sectional arch shape. The top wall 42 is formed with the discharge hole 45 communicating with the inside of the inner container 10 through a communication passage R described later.
At this time, the discharge hole 45 is formed coaxially with the container axis O in the deepest deepest part of the top wall part 42 in the left-right direction. In the illustrated example, the case where the discharge hole 45 is formed in a circular shape in plan view having the same diameter as the inner diameter of the discharge cylinder portion 41 is exemplified. However, the opening is smaller than the inner diameter of the discharge cylinder portion 41. The discharge hole 45 can be appropriately changed to another form for discharging the contents in the inner container 10.

  As shown in FIG. 1 and FIG. 2, a second convex rib 44 a is annularly projected toward the inner side in the radial direction at the lower end portion of the fitting cylinder portion 44, and the discharge body 40 is moved upward. (See FIG. 7), the second convex rib 44a is engaged with the first convex rib 35b formed on the mounting cylinder portion 35 of the exterior portion 30 from below. Thereby, the further upward movement of the discharge body 40 is regulated.

By the way, when the discharge body 40 moves to the rising end, a gap communicating with the outside is defined between the portion located on the rear side of the mounting cylinder portion 35 of the exterior portion 30 and the second convex rib 44a. The Therefore, when the discharge body 40 moves to the rising end, the internal space E1 communicates with the outside through the vertical groove 35a.
The second convex rib 44a is provided with an intermittent portion, the mounting cylinder portion 35 is formed with a slit, or a gap is provided between the second convex rib 44a and the mounting cylinder portion 35. The inflow of outside air, which will be described later, may be allowed.

  Here, the discharge cap 3 is formed with an introduction hole 36 that allows the intake hole 12 to communicate with the outside. The introduction pore 36 communicates with the intake hole 12 through the vertical groove 17 and communicates with the outside through the internal space E1 and the vertical groove 35a. As shown in FIGS. 5 and 6, the introduction pore 36 is formed in a groove shape in the interior portion 20, and is continuously formed in the second seal cylinder portion 23 and the outer flange portion 22 of the interior portion 20. Yes. The introduction pore 36 has a V shape in a cross-sectional view orthogonal to the extending direction. The groove width of the introduction pore 36 gradually becomes narrower from the opening side toward the bottom wall side. As shown in FIG. 1, the introduction hole 36 is preferably formed in a portion where the position in the circumferential direction coincides with the intake hole 12, but it does not need to coincide. In the illustrated example, one introduction pore 36 is formed in a portion located on the rear side of the interior portion 20.

  Further, the inside of the discharge cylinder portion 41 of the discharge body 40 functions as a communication path R communicating with the discharge hole 45. Further, on the inner peripheral surface of the discharge cylinder portion 41, the portion located on the front portion 42a side of the top wall portion 42 makes it easy to return the contents flowing out from the discharge holes 45 into the inner container 10 or A vertical groove 41a for promoting outflow is formed from the discharge hole 45 to a substantially intermediate portion in the container axis O direction.

  As shown in FIGS. 1 to 3, a pair of engaged protrusions 47 project from the discharge cylinder portion 41 of the discharge body 40 configured as described above toward the outside in the radial direction. These engaged protrusions 47 are arranged so as to be lined up in the left-right direction across the container axis O, are formed so as to protrude outward in the radial direction from the top wall portion 42, and the outer shape thereof is a square in a side view. It is formed into a shape.

The upper surface of the top wall portion 42 of the discharge body 40 described above is covered with a flexible covering body 60 so as to cover the discharge holes 45 formed in the top wall portion 42.
As shown in FIG. 3, the covering body 60 is formed in a shape along the outer peripheral edge of the top wall portion 42, covers the entire top wall portion 42 and covers the top wall portion 42. It is fixed to the upper surface via a fixing portion 61. The adhering portion 61 surrounds the discharge hole 45 from the outside in the radial direction and opens at the center (a part in the circumferential direction) of the top wall portion 42 on the front portion 42a side. Therefore, the covering body 60 is fixed to the upper surface of the top wall portion 42 along the outer peripheral edge of the top wall portion 42 except for the central portion of the top wall portion 42 on the front portion 42a side.
Thus, a portion where the fixing portion 61 is opened and the covering body 60 and the top wall portion 42 are not fixed is formed on the front portion 42a side of the top wall portion 42, and that portion (the opening portion of the fixing portion 61) is formed. ) Is the channel port 62. That is, the flow path port 62 is located on the opposite side of the hinge portion 4 with the container axis O interposed therebetween.

  The covering body 60 is curved following the curvature of the top wall portion 42, and a portion of the covering body 60 located inside the fixing portion 61 is a non-fixing portion 63. It is closely attached to the upper surface of the slab. Thereby, the discharge hole 45 is sealed by the non-adhering part 63, and the airtightness of the inner container 10 is ensured. The non-fixed portion 63 of the covering body 60 can be separated from the upper surface of the top wall portion 42 by, for example, elastically bulging (inverted deformation) in a direction away from the upper surface of the top wall portion 42. That is, the non-fixed portion 63 of the covering body 60 seals the discharge hole 45 so as to be freely opened and closed.

  As a method for fixing the covering 60 to the upper surface of the top wall portion 42, for example, adhesion using an adhesive sealant, an adhesive, or the like, or welding such as thermal welding may be considered. Examples of the covering 60 include a general film that is not easily torn (applicable regardless of stretchability), a flexible resin sheet, or a metal foil. Examples include layers and laminates.

  As shown in FIGS. 1 and 2, the discharge valve body 50 is formed in the shape of a top tube disposed coaxially with the container axis O, and its lower end is substantially the same as the inner flange portion 24 of the interior portion 20. It arrange | positions inside the guide cylinder part 25 in the state which made the height correspond. As shown in FIGS. 1, 2 and 4, the lower end portion of the discharge valve body 50 is internally provided via a plurality of bridge portions 51 that extend outward in the radial direction and are arranged at intervals in the circumferential direction. The inner flange portion 24 of the portion 20 is connected to the inner peripheral edge portion. A discharge opening 52 is provided between the bridge portions 51 adjacent to each other in the circumferential direction.

The lower end portion of the discharge cylinder portion 41 of the discharge body 40 is fitted in a liquid-tight and detachable manner between the cylinder body 50a of the discharge valve body 50 and the guide cylinder portion 25 of the interior portion 20. ing. Therefore, the communication between the communication passage R and the inside of the inner container 10 through the discharge opening 52 is blocked. On the other hand, when the discharge body 40 moves upward (see FIG. 7), the lower end of the discharge cylinder portion 41 Since the portion is separated from the discharge valve body 50, the communication path R and the inside of the inner container 10 communicate with each other through the discharge opening 52.
Thus, using the discharge valve body 50, the communication between the inside of the inner container 10 and the discharge hole 45 and the blocking thereof can be switched as the discharge body 40 moves up and down.

  As shown in FIGS. 1 to 3, the hinge cap 5 is formed in a cylindrical shape with a peripheral wall portion 80 and a top plate portion 81, and is attached to the exterior portion 30 so as to cover the discharge cap 3. . The hinge cap 5 is connected to the exterior part 30 via the hinge part 4, and is attached to and detached from the exterior part 30 by opening and closing around the hinge part 4. In addition, the hinge cap 5 is mounted | worn in the stable state because the lower end part of the surrounding wall part 80 fits in the step part 33 of the exterior part 30. FIG.

The peripheral wall portion 80 is formed with a knob piece 82 projecting outward in the radial direction at a portion located on the opposite side of the radial direction across the container axis O from the hinge portion 4. It is possible to easily perform an opening / closing operation (especially an opening operation) of the hinge cap 5 by using.
A pair of engaging portions 83 that engage with the engaged protrusions 47 formed on the discharge body 40 are disposed on the top plate 81 so as to sandwich the engaged protrusions 47 from the outside in the left-right direction. . These engaging portions 83 project downward from the top plate portion 81, and project from the plate piece portion 83a parallel to the front-rear direction and radially inward from the lower end of the plate piece portion 83a. And an engaging protrusion 83b that is detachably engaged with the engaged protrusion 47 from below.

(Use of discharge container)
Next, the use of the discharge container 1 configured as described above will be described.
First, as shown in FIGS. 1 and 2, when the hinge cap 5 is not attached to the exterior portion 30 of the discharge cap 3, the discharge valve body 50 communicates the inside of the inner container 10 with the discharge hole 45. Is blocked, and the non-fixed portion 63 of the covering body 60 covered on the upper surface of the top wall portion 42 seals the discharge hole 45. Therefore, in an unused state, the sealing property of the inner container 10 can be ensured, and the contents can be prevented from unexpectedly flowing out from the discharge hole 45 and leaking to the outside.

  Next, when discharging the contents, first, an opening operation for rotating the hinge cap 5 around the hinge portion 4 is performed to remove the contents from the exterior portion 30. Then, with this opening operation, the engaging portion 83 rises while the engaging protrusion 83b of the engaging portion 83 provided on the top plate portion 81 engages with the engaged protrusion 47 of the discharge body 40 from below. Will move. As a result, as shown in FIG. 7, the lower end portion of the discharge cylinder portion 41 constituting the discharge body 40 is pulled upward from between the cylinder body 50 a of the discharge valve body 50 and the guide cylinder portion 25 of the interior portion 20. It leaves | separates from the discharge valve body 50, and, thereby, the inside of the inner container 10 and the discharge hole 45 are connected. Further, in this process, the engagement protrusion 83b of the engagement portion 83 gets over the engagement protrusion 47 of the discharge body 40 from below to above, and the engagement between the engagement portion 83 and the discharge body 40 is released. . Therefore, the hinge cap 5 can be greatly opened.

  Further, when the discharge body 40 moves upward, the discharge cylinder portion 41 and the guide cylinder portion 25 of the interior portion 20 are in sliding contact with each other, and the guide cylinder portion 25 guides the upward movement of the discharge body 40. It will move up stably. Also, the ejector 40 that has moved upward is engaged with the first convex ribs 35b of the mounting cylinder part 35 of the exterior part 30 from below by the second convex ribs 44a formed on the fitting cylinder part 44. The above upward movement is restricted.

Then, after the hinge cap 5 is detached as described above, the container body 2 is pushed inward in the radial direction to be squeezed (squeezed) to increase the internal pressure of the inner container 10. Thereby, since the internal pressure of the inner container 10 can be raised, the contents can flow out from the discharge hole 45 through the discharge opening 52 and the communication path R. Then, the covering 60 is pressed by the contents flowing out from the discharge hole 45, and the non-fixed portion 63 of the covering 60 is, for example, reversely deformed upward from the top surface of the top wall portion 42, and protrudes upward. Bulges into a dome shape.
For this reason, a flow path R1 communicating with the discharge hole 45 is defined between the covering body 60 and the top surface of the top wall section 42, and a flow path port 62 opened outward at the opening portion of the fixing section 61. Is defined.

  Therefore, the contents flowing out from the discharge hole 45 can be discharged from the flow path port 62 through the flow path R1. Moreover, since the flow passage port 62 is defined on the opposite side of the radial direction from the hinge portion 4, the contents can be discharged without being obstructed by the hinge cap 5.

  Further, when stopping the discharge of the contents, the pressing of the container body 2 is stopped or released, and the outflow of the contents from the discharge holes 45 is stopped. Thereby, the pressing force from the contents applied to the covering body 60 is released, and the non-fixed portion 63 of the covering body 60 separated from the upper surface of the top wall portion 42 is elastic, for example, as shown in FIG. Or it is restored to its original state by the internal pressure (negative pressure) of the inner container 10 and is in close contact with the upper surface of the top wall 42. Thereby, the flow path port 62 and the flow path R1 are closed, and the discharge hole 45 is sealed, so that the airtightness of the inner container 10 can be ensured again.

  In particular, when the discharge of the contents is stopped, the top wall portion 42 of the present embodiment is inclined upward, and the front portion 42a side is located above the rear portion 42b side. The contents inside easily return to the discharge hole 45 smoothly due to the inclination of the top wall portion 42. Therefore, it is possible to improve the drainage of the contents and to suppress dripping of the contents after ejection.

  The container body 2 of the present embodiment is a delami bottle, and when the squeeze deformation of the outer container 11 is released while the inner container 10 is deformed and deformed by the discharge of the contents, the container body 2 is interposed between the inner container 10 and the outer container 11. Negative pressure is generated. At this time, the introduction pore 36 allows outside air to flow toward the intake hole 12. That is, the vertical groove 17, the introduction pore 36, the internal space E <b> 1, and the vertical groove 35 a function as an outside air inflow path 46 through which outside air flows into the intake hole 12. Then, when the outside air is sucked between the inner container 10 and the outer container 11 through the intake hole 12, the inner container 10 is separated from the outer container 11 as shown in FIG. Defined. Therefore, the outer container 11 can be smoothly restored and deformed while reducing the volume of the inner container 10.

Here, when the outer container 11 is squeezed again to discharge the contents in the state where the gap space E2 is defined between the inner container 10 and the outer container 11, the outer container 11 and the inner container 10 The outflow of air between them is regulated by the introduction pores 36. At this time, the air in the gap space E2 is increased in pressure and tends to flow out from the intake hole 12 through the introduction hole 36, but the introduction hole 36 functions as an orifice and the air is introduced. A large resistance is imparted when passing through the pores 36 and the outflow to the outside is restricted. That is, the introduction pore 36 functions as an orifice, and a predetermined resistance can be generated in the outside air (air) flowing between the intake hole 12 and the outside through the introduction pore 36. Such a function can be realized, for example, by setting the cross-sectional area of the introduction pore 36 formed in a groove shape based on the rigidity and restoring force of the outer container 11.
When the outflow of air between the outer container 11 and the inner container 10 is restricted by the introduction pores 36, the inner pressure of the gap space E2 increased by the squeeze deformation of the outer container 11 does not rapidly decrease, and the outer The pressing force acting on the container 11 can be efficiently applied to the inner container 10 via the gap space E2, and the inner pressure of the inner container 10 can be reliably increased.

After the discharge of the contents is completed, the closing operation for rotating the hinge cap 5 around the hinge portion 4 is performed to attach the hinge cap 5 to the exterior portion 30 of the discharge cap 3 again. Then, with this closing operation, the engaging member 83 moves downward while the engaging protrusion 83b of the engaging portion 83 contacts the engaged protrusion 47 of the discharging member 40 from above, so that the discharging member 40 is lowered. Will move. Further, as the discharge body 40 moves downward, the lower end portion of the discharge cylinder portion 41 is fitted again between the cylinder body 50 a of the discharge valve body 50 and the guide cylinder portion 25 of the interior portion 20, and passes through the discharge opening 52. The communication between the inside of the inner container 10 and the communication path R is blocked. That is, the communication between the inside of the inner container 10 and the discharge hole 45 is blocked again.
Thereby, the airtightness of the inner container 10 can be further ensured, and in combination with the seal of the discharge hole 45 by the covering body 60, the contents may unexpectedly flow out of the discharge hole 45 and leak to the outside. It can be effectively suppressed.

Further, in the process of closing the hinge cap 5, the engaging protrusion 83 b of the engaging portion 83 gets over the engaged protrusion 47 of the discharge body 40 from above to below, and the engaging protrusion 83 b of the engaged protrusion 47 It will be located on the lower side.
When the discharge body 40 moves downward, the guide cylinder portion 25 and the discharge cylinder portion 41 of the interior portion 20 are in sliding contact with each other, and the guide cylinder portion 25 causes the discharge body 40 to move downward. Since the guide is provided, the discharge body 40 stably moves downward.

  In the above-described embodiment, the contents are discharged by squeezing the container body 2. However, the container body 2 is inclined forward and the flow path port 62 is directed downward, and the weight of the contents is reduced. You may discharge using. In this case, in order to stop the discharge of the contents, the container body 2 may be returned to the original upright posture. Furthermore, the contents may be discharged by squeezing the container body 2 while tilting the container body 2 forward.

  As described above, according to the discharge container 1 according to the present embodiment, instead of providing the air valve as in the prior art, the introduction hole 36 is provided, so that the air can be removed when the outer container 11 is squeezed. While suppressing leakage, it becomes possible to introduce air when the outer container 11 is restored and deformed, and the number of parts can be reduced.

  In addition, since the introduction pore 36 is formed in a groove shape, the introduction pore 36 has a flow path length on the outer surface of the discharge cap 3 (in this embodiment, on the outer surface of the interior portion 20). And can be formed. Thereby, when the outer container 11 is squeezed, the outflow of air between the outer container 11 and the inner container 10 can be effectively suppressed.
