  By the way, there is a demand that such a discharge container wants to secure the sealability which seals the contents, even after peeling off the seal material. However, when the sealing material is peeled off, a part of the sealing material (such as an adhesive) remains at the tip of the nozzle, or when the sealing material is heat-sealed, the nozzle tip is deformed. Since the nozzle tip has a low degree of flatness, it is difficult to secure sealing performance by using the nozzle tip as a sealing surface.

  This invention is made in view of such a situation, The objective is to provide the discharge container which can ensure the higher sealing property of the content, even after peeling a sealing material.

(1) The discharge container according to the present invention includes a container body in which the content is stored, and an opening of the container body which covers the opening portion of the container body, and the discharge port of the content is formed. A sealing material which closes the outlet and elastically displaces the closing plate toward the inside of the container body to be releasably adhered, and the closing plate restored and displaced due to peeling of the sealing material It has a push-in portion pushed inward, and an apertular cylindrical lid portion provided with a seal portion which closes the discharge port in an openable manner.

  According to the discharge container of the present invention, when the sealing material adhered to the discharge container is peeled off, the closing plate elastically displaced toward the inside of the container body by the sealing material is restored and displaced toward the outside of the container body Do. The discharge port of the contents is formed in the closing plate, and the closing plate is lifted toward the outside of the container body by peeling off the sealing material. The lid pushes the closing plate raised toward the outside of the container body toward the inside of the container body to openably close the discharge port. Since the closing plate is elastically displaced (retracted) inside the container body by the sealing material, a part of the sealing material does not remain even if it is peeled off. Even if it does, it will not be deformed under the influence of it. Therefore, high sealing performance can be ensured even after peeling the sealing material.

(2) The lid portion has a ceiling wall seal portion having a smooth pressing surface which presses over the entire circumference in the radial direction outer side of the discharge port on the upper surface of the closing plate as the push-in portion and the seal portion. You may have.

  In this case, since the radially outer side of the discharge port on the upper surface of the closing plate is pressed over the entire circumference by the smooth pressing surface of the top wall seal portion, high sealing performance can be ensured. Further, since the closing plate is elastically displaceable, it is elastically displaced so as to follow a smooth pressing surface by the pressing of the top wall seal portion, thereby enhancing the adhesion between the upper surface of the closing plate and the pressing surface of the top wall sealing portion Therefore, higher sealing performance can be ensured.

(3) The discharge port may be formed with a valve which is opened outward when the internal pressure of the container body is higher than the atmospheric pressure, and closed by an elastic action when the internal pressure is substantially equal to the atmospheric pressure.

  In this case, it is possible to make the discharge container free of liquid drainage.

(4) The valve may be formed in a slit shape.

  In this case, when the slit is closed after the discharge of the contents, the contents on the outside of the discharge port and the contents on the inside are separated, so the liquid drainage property is further improved.

(5) The container main body includes an inner container which is reduced in volume as the content decreases, and an outer container provided with the inner container and an intake hole for sucking in the outside air between the inner container and the inner container. And a plug member disposed at the upper end opening edge of the mouth of the laminate peelable container, the plug member comprising a bottomed cylindrical inner plug body, and the inner plug member. The seal member has a communication hole formed in a bottom wall portion of the plug body and communicating the discharge port with the inner side of the inner container, and a discharge valve closing the communication hole so as to be openable. It may be releasably adhered to the upper end opening edge of the inner plug body.

  In this case, when the laminated peeling container is pressed to discharge the contents, and then the pressure on the laminated peeling container is released, the discharge valve causes the inflow of the contents and the outside air from the discharge port toward the inside of the inner container. Can be prevented, and outside air can be introduced between the outer container and the inner container from the air intake hole provided in the outer container to restore the outer container to its original shape while reducing the volume of the inner container. The contents can be discharged without being replaced with the outside air, whereby the contents remaining inside the laminate peeling type container can not easily come in contact with the air, and the deterioration or deterioration thereof can be suppressed. A plug member having a bottomed cylindrical inner plug body is disposed at the upper opening edge of the opening of the peelable container, and the sealing material is releasably adhered to the upper opening edge of the inner plug body. Therefore, even if the sealing material is peeled off, the inner container is not damaged.

(6) The closing plate closes the upper end opening of the inside plug body, and the content storage capable of storing contents between the closing plate and the discharge valve inside the inside plug body Space may be formed.

  In this case, since the contents can be stored in the contents storage space formed inside the inside plug body and the filling seal by the contents can be formed, it is suppressed that outside air enters the inside of the inner container from the discharge port. can do. In particular, when containing relatively high-viscosity contents including some solid matter such as sauce, miso, ketchup and mayonnaise, the closing plate is temporarily subjected to some force directed to the inside of the container body. Even in this case, since the content having such a high viscosity is accommodated, the closure plate can be supported from the lower side, so the closure plate can not be easily separated from the lid portion, and higher sealing performance can be ensured.

  According to the discharge container of the present invention, higher sealability of the contents can be ensured even after peeling the seal material.

First Embodiment
Hereinafter, a discharge container according to a first embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the discharge container 1 of the present embodiment has a container body 2, a closing plate 3, a sealing material 4, and a lid 5 (lid 41). The discharge container 1 accommodates relatively viscous contents including some solids including, for example, pasta sauce, sauces such as pizza sauce, ketchup, mayonnaise, and liquid seasonings such as miso. It is possible.

  The bottomed cylindrical container body 2, the top cylindrical closing plate 3, the sealing material 4 having a circular shape in plan view, and the top cylindrical lid 5 have their respective central axes positioned on a common axis. It is arranged. In this embodiment, this common axis is referred to as the container axis O, the side of the mouth 2a of the container body 2 along the container axis O is referred to as the upper side, and the bottom side (not shown) of the container body 2 is referred to as the lower side. Further, in a plan view seen from the container axis O direction, a direction intersecting the container axis O is referred to as a radial direction, and a direction circling around the container axis O is referred to as a circumferential direction.

  The container body 2 has a laminated / peelable container 12, an inner plug member 20, and a mounting tube portion 40. The peel-off type container 12 includes an inner container 10 which is reduced in volume as its content decreases, and an outer container 11 in which the inner container 10 is installed. The peelable container 12 is, for example, a so-called delamination container which is formed by blow molding and the outer surface of the inner container 10 is peelably laminated on the inner surface of the outer container 11. In addition, as blow molding, for example, the laminated parison combined in a double (inner and outer) by extrusion molding etc. may be formed, and the container main body 2 may be formed by blow molding this laminated parison (extrusion blow molding ).

  Further, preforms for the outer container and preforms for the inner container are separately formed by injection molding or the like, and these are combined in duplicate (inside and outside) to integrally carry out biaxial stretch blow molding of the container main body 2 May be formed. Furthermore, after the preform for the outer container is first biaxially stretch blow molded to form the outer container 11, the preform for the inner container is disposed inside the outer container 11, and then the preform for the inner container is formed. The container body 2 may be formed by biaxial stretch blow molding. In addition, after the laminated preform is formed, the container body 2 may be formed by biaxial stretch blow molding the preform. Moreover, after shape | molding the inner container 10 and the outer container 11 separately, you may combine these. In addition, these shaping | molding methods are an example, Comprising: It does not specifically limit.

  The inner container 10 and the outer container 11 may be made of a synthetic resin, and may be the same material or different materials as long as the inner container 10 is a combination capable of reducing the volume (for example, peelable) independently of the outer container 11. May be. As an example of a synthetic resin material, PET (polyethylene terephthalate), PP (polypropylene), PE (polyethylene), nylon (polyamide), EVOH (ethylene-vinyl alcohol copolymer) etc. are mentioned, for example. Out of these synthetic resin materials, it is preferable that the outer container 11 and the inner container 10 be formed in a combination that allows peeling (no compatibility).

  The container body 2 is formed in a bottomed cylindrical shape in which a mouth 2a, a shoulder 2b, a body (not shown), and a bottom (not shown) are continuously provided in this order from the upper side to the lower side. The shoulder portion 2 b gradually expands in diameter from the upper side to the lower side. The body is formed in, for example, a circular shape in a cross sectional view. The outer container 11 constituting the container main body 2 is squeeze-deformable, and with the squeeze deformation of the outer container 11, the inner container 10 is reduced in volume. Therefore, at least a portion of the outer container 11 located on the trunk portion is elastically deformable radially inward (inside of the container).

  The mouth 2a of the container body 2 extends upward from the upper end opening of the shoulder 2b. A fitting protrusion 13 for attaching the lid 5 is formed on the outer peripheral surface of the mouth 2 a of the container body 2. The mouth 12 a of the laminated peelable container 12 is configured such that the mouth 10 a of the inner vessel 10 and the mouth 11 a of the outer vessel 11 are stacked. The upper end portion of the opening 10 a of the inner container 10 is folded back in a ring shape projecting radially outward, and the folded portion is disposed at the upper opening edge of the opening 11 a of the outer container 11. Therefore, the opening 11 a of the outer container 11 is closed by the inner container 10.

  In the opening 11 a of the outer container 11, an intake hole 14 is formed between the outer container 11 and the inner container 10 for drawing in the outside air via an outside air introduction channel 70 described later. Note that the intake holes 14 may be formed in the trunk portion or the bottom portion of the outer container 11 other than the mouth portion 11a, and direct intake of the outside air. Further, for example, when the intake hole 14 is formed in the trunk of the outer container 11, an air valve (check valve) (not shown) is disposed in the trunk of the outer container 11, and the air valve While air can be drawn between the outer container 11 and the outer container 11, air may be restricted from flowing out between the inner container 10 and the outer container 11. The container main body 2 may be squeezed while preventing the air from flowing out between the inner container 10 and the outer container 11 with a fingertip without providing the air valve.

  The inner plug member 20 has an annular inner plug outer peripheral portion 21 disposed at the upper end opening edge of the opening 12 a of the laminated peelable container 12 and a bottomed end provided continuously with the radially inner end edge of the inner plug outer peripheral portion 21. And a cylindrical inner plug body 22. The inner plug outer peripheral portion 21 and the inner plug main body 22 are disposed coaxially with the container axis O. The inner plug outer peripheral portion 21 protrudes outward in the radial direction with respect to the upper end opening edge of the opening 12 a of the layered peeling type container 12. The inner plug body 22 projects downward in the radial direction from the upper opening edge of the opening 12 a of the laminated peeling container 12, and fits inside the opening 12 a of the laminated peeling container 12 to peel off the lamination The mouth 12 a of the mold container 12 is sealed.

  A communication hole 23 is formed in the bottom wall 22 a of the inside plug body 22. The communication hole 23 is formed coaxially with the container axis O. In addition, a discharge valve 24 is disposed in the bottom wall 22a of the inner plug body 22 so as to open the communication hole 23 in an openable manner. The discharge valve 24 has a valve body 25 that abuts radially outward of the communication hole 23 on the top surface of the bottom wall 22 a of the inner plug body 22. The valve body 25 is formed, for example, in a circular shape in a plan view, and is disposed coaxially with the container axis O. The valve body 25 is connected to the inner peripheral surface of the cylindrical portion 26 fitted inside the inside plug body 22 via a plurality of elastic arms 27.

  The elastic arm 27 is formed to extend in, for example, the circumferential direction, thereby securing appropriate springiness, and the radial inner end portion is connected to the outer peripheral edge portion of the valve body 25, and The outer end is connected to the cylindrical portion 26. Then, the elastic arm 27 elastically deforms so as to move the valve body 25 upward when the contents inside the inner container 10 pass through the communication hole 23 of the inner plug main body 22, and the valve body 25 is moved. The upper surface of the bottom wall 22a of the inside plug body 22 is separated.

  The closing plate 3 closes the upper end opening 22A of the inside plug body 22. The closing plate 3 is formed in a top cylindrical shape, for example, by a soft material such as rubber or an elastomer. In addition, although the closure board 3 of this embodiment is formed from silicone rubber, it is not limited to the said silicone rubber. The closing plate 3 includes a closing plate main body 31 in which the discharge port 31a of the contents is formed, a fitting peripheral wall 32 fitted to the inside of the inner plug body 22, an upper end of the fitting peripheral wall 32 and the closing plate main body And a connecting portion 33 for connecting with the radially outer end edge of 31. The lower end of the fitting peripheral wall portion 32 abuts on the upper end of the cylindrical portion 26. A fitting protrusion 32 a is formed on the outer peripheral surface of the fitting peripheral wall portion 32. The fitting projection 32 a is undercut and fitted to the fitting groove 22 c formed on the inner peripheral surface of the inner plug body 22.

  The connection portion 33 is a leaf spring portion, and urges the closing plate main body 31 upward with respect to the fitting peripheral wall portion 32 in the state shown in FIGS. 1 and 2. The connecting portion 33 extends continuously over the entire circumference in the circumferential direction. The connecting portion 33 has, for example, an annular shape in a plan view as viewed from the axial direction of the container axis O, and is disposed coaxially with the container axis O. The connecting portion 33 is thinner than the closing plate main body 31 and the fitting peripheral wall portion 32. When the closing plate main body 31 is pressed, the connecting portion 33 is elastically deformed.

  The closing plate main body 31 is configured to be elastically displaceable to the inside and the outside of the container main body 2 by the connecting portion 33. Specifically, as shown in FIG. 1, the closing plate main body 31 is elastically displaceable inside the container main body 2 which is lower than the upper opening edge 22 b of the inner plug main body 22. Further, as shown in FIG. 3, the closing plate main body 31 can be elastically displaced to the outside of the container main body 2 which is above the upper opening edge 22 b of the inner plug main body 22. The closing plate main body 31 has, for example, a disk shape in a plan view as viewed from the axial direction of the container axis O, and is disposed coaxially with the container axis O.

  A discharge port 31 a is formed at the center of the closing plate main body 31. As shown in FIG. 4, the discharge port 31a is formed with a slit-like valve, and is opened outward when the internal pressure of the container body 2 is higher than atmospheric pressure, and closed by elasticity when the internal pressure is approximately equal to atmospheric pressure. Be done. The discharge port 31 a is formed so that three slits intersect at the top of the disc-shaped closure plate main body 31. Protrusions 31 b are formed on the six tongues formed by the three slits. As shown in FIG. 3, the protrusion 31 b is formed in a hemispherical shape on the upper surface of the closing plate main body 31. In addition, the discharge port 31a may be formed by one slit, and two slits may be orthogonally formed. Further, the discharge port 31a may be formed by four or more slits.

  As shown in FIG. 1, the sealing material 4 is adhered to the container body 2 so as to be removable (removed), closes the discharge port 31 a, and elastically displaces the closing plate 3 toward the inside of the container body 2. The sealing material 4 is, for example, a thin sheet-like member made of paper or synthetic resin, and has a configuration in which an aluminum foil having gas barrier properties and light shielding properties is laminated on a part thereof (so-called aluminum seal). The sealing material 4 is releasably adhered to the upper end opening edge 22 b of the inner plug body 22 by heat fusion. The seal member 4 is provided with a knob (not shown) so that the seal 4 can be peeled off from the upper opening edge 22b of the inner plug body 22 by pulling up the knob with a finger. ing. The sealing material 4 may be bonded to the upper end opening edge 22 b of the inner plug body 22 and / or the upper end edge of the fitting peripheral wall portion 32. That is, the sealing material 4 may be bonded to the closing plate 3. Therefore, the fact that the sealing material 4 is peelable here means that the sealing material 4 is removable from the discharge container 1.

  By adhering the sealing material 4 to the container main body 2, the storage property of the contents can be secured. As an example, the oxygen permeability of the single layer of the laminated / peelable container 12, more specifically, of the single layer of the delamination container in which the EVOH layer is provided in the inner container as the barrier layer, is 0.002 g / day / container. Moreover, the oxygen permeability of the discharge container which attached the conventional cap without adhering the aluminum seal | sticker to the said delamination container is 0.020 g / day / container. Then, as in the embodiment, for example, the lid 5 (cap) is attached to the exfoliation peelable container 12 in which the EVOH layer is provided on the inner container 10 as a barrier layer, and the discharge is performed with the sealing material 4 (aluminum seal) adhered. The oxygen permeability of the container 1 is 0.002 to 0.005 g / day / container.

  The mounting tube portion 40 is mounted to the mouth 2 a of the container body 2. The mounting cylindrical portion 40 is formed in a cylindrical shape that covers the radially outer side of the mouth 2 a of the container body 2. A first fitting groove 43 is formed on the inner peripheral surface of the mounting cylindrical portion 40, and the fitting projection 13 formed on the outer peripheral surface of the opening 2a of the container body 2 is undercut and fitted. The mounting tube 40 may be, for example, screwed to the opening 2 a of the container body 2.

  Of the inner peripheral surface of the mounting cylindrical portion 40, above the first fitting groove 43, there is formed a second fitting groove 44 fitted on the radially outer end edge of the inner plug outer peripheral portion 21. . For example, a ventilation groove (not shown) for taking in the outside air is formed between the inner plug outer peripheral portion 21 and the second fitting groove 44. The vent groove communicates with the outside air introduction channel 70. The outside air introduction channel 70 is formed between the outer peripheral surface of the opening 2a of the container body 2 and the inner peripheral surface of the mounting cylindrical portion 40, and the inner peripheral reinforcement of the mounting cylindrical portion 40 extending along the container axis O It is divided circumferentially by a rib.

  The lower end portion of the mounting cylindrical portion 40 is closely fitted to a portion of the mouth portion 2 a of the container main body 2 located below the intake hole 14. Thus, the communication between the intake hole 14 and the outside through the lower end opening of the mounting cylinder 40 is blocked. Therefore, when the air valve (not shown) provided in the vent groove (not shown) or the outside air introduction flow path 70 is opened, the outside air introduction flow path 70 and the intake hole 14 communicate with each other, and the outside air flows through the air intake hole 14 10 and between the outer container 11.

  The lid 5 includes a top cylindrical lid 41 connected to the mounting cylinder 40 via a hinge 42. The lid portion 41 includes a peripheral wall portion 50 connected to the mounting cylindrical portion 40 via the hinge portion 42, and a top wall seal portion 51 (push-in portion and seal portion) continuously provided at the upper end portion of the peripheral wall portion 50. Prepare. On the inner peripheral surface of the peripheral wall portion 50, an engagement concave portion 52 engaged with the engagement convex portion 45 formed on the upper end portion of the mounting cylindrical portion 40 is annularly formed. Then, when the lid portion 41 is rotated about the hinge portion 42, the engagement convex portion 45 on the mounting cylindrical portion 40 side and the engagement concave portion 52 on the lid portion 41 side can be engaged. As a result, the lid 41 is in a closed state in which the mouth 2 a of the container body 2 or the closing plate 3 is covered. As shown in FIG. 4, a pair of auxiliary arm portions 42 a are provided on both sides of the hinge portion 42. The pair of auxiliary arm portions 42 a stabilizes the opening / closing operation of the lid portion 41 by reinforcing the connection between the mounting cylindrical portion 40 and the lid portion 41 by the hinge portion 42.

  The ceiling seal portion 51 pushes the closure plate 3 restored and displaced by the peeling of the seal material 4 as shown in FIG. 3 toward the inside of the container main body 2 as shown in FIG. 2 so that the discharge port 31a can be opened. Shut up. The top wall seal portion 51 has an upside-down frusto-conical shape that is recessed downward toward the inside of the peripheral wall portion 50, and is disposed coaxially with the container axis O. The top wall seal portion 51 has a smooth pressing surface 53 for pressing the annular surface 31 c (see FIG. 4) on the outer side in the radial direction of the discharge port 31 a on the upper surface of the closing plate 3 over the entire circumference. The pressing surface 53 protrudes downward at the upside-down frusto-conical lower bottom portion of the top wall seal portion 51.

  In the discharge container 1 configured as described above, when discharging the contents, first, the lid portion 41 of the lid 5 is pivoted upward around the hinge portion 42. In addition, when the sealing material 4 adheres to the container main body 2, the sealing material 4 is peeled off from the container main body 2 by pulling up the knob part not shown. When the sealing member 4 is peeled off, the closing plate 3 elastically displaced toward the inside of the container main body 2 by the sealing member 4 is restored and displaced toward the outside of the container main body 2 as shown in FIG. Thereafter, for example, the outer container 11 is squeeze deformed (elastically deformed) radially inward while tilting or vertically inverting the container body 2. As a result, the inner container 10 is deformed inward in the radial direction together with the outer container 11 to reduce the volume, so the internal pressure of the inner container 10 is increased.

  Then, first, the valve body 25 of the discharge valve 24 disposed on the inner container 10 side of the inner plug body 22 separates from the bottom wall portion 22 a of the inner plug body 22, and the communication hole 23 of the inner plug body 22 opens. Be done. When the communication hole 23 of the inside plug body 22 is opened, the contents flow into the inside of the inside plug body 22 and the internal pressure of the inside plug body 22 rises. Then, next, the slit is opened at the discharge port 31a of the closing plate 3 disposed at the upper end opening 22A of the inner plug body 22, and the discharge port 31a and the inner container 10 communicate with each other through the inner plug body 22. The content accommodated inside the inner container 10 is discharged to the outside from the discharge port 31a.

  Thereafter, when the squeeze deformation of the outer container 11 is stopped or released, the increase of the inner pressure of the inner container 10 is stopped or the inner pressure of the inner container 10 is decreased, and the slit of the discharge port 31a is closed. Further, in the discharge valve 24, when the valve body 25 abuts on the bottom wall portion 22 a of the inside plug main body 22 by the urging of the elastic arm 27, the communication hole 23 of the inside plug main body 22 is closed. As a result, the communication between the discharge port 31a and the inner container 10 is shut off. For this reason, discharge of the content is stopped.

  Further, by releasing the squeeze deformation of the outer container 11, the outer container 11 starts to be restored and deformed, so a negative pressure is generated between the outer container 11 and the inner container 10. Then, this negative pressure acts on the outside air introduction channel 70 through the intake hole 14, whereby the air vent groove (not shown) between the inner plug outer peripheral portion 21 and the second fitting groove 44 Outside air flows inside. Outside air that has flowed into the inside of the lid 5 flows between the inner container 10 and the outer container 11 through the air inlet 14. As a result, even if the outer container 11 is restored and deformed, the outer surface of the inner container 10 is separated from the inner surface of the outer container 11, and the inner container 10 is maintained in the state of reduced volume deformation.

  When the discharge of the contents from the discharge container 1 is completed, the lid 41 of the lid 5 is rotated about the hinge 42, and the engagement convex 45 on the mounting cylinder 40 and the engagement concave on the lid 41 are made. Engage with 52. As a result, as shown in FIG. 2, the lid portion 41 is in a closed state in which the closing plate 3 is covered. In the closed state, the top wall seal portion 51 of the cover 41 pushes the closing plate 3, which has been restored and displaced due to the peeling of the sealing material 4, toward the inside of the container body 2. The lower surface of the top wall seal portion 51 is a smooth pressing surface 53, and presses the radially outer side of the discharge port 31a on the upper surface of the closing plate 3 over the entire circumference. As a result, the contents can be prevented from leaking from the discharge port 31 a to the outside in the radial direction of the annular surface 31 c of the closing plate 3.

  As described above, according to the discharge container 1 according to the present embodiment, when the sealing material 4 adhered to the container main body 2 is peeled off, as shown in FIG. The closure plate 3 which has been elastically displaced is restored and displaced toward the outside of the container body 2 as shown in FIG. A discharge port 31 a for contents is formed in the closing plate 3, and the closing plate 3 is lifted toward the outside of the container main body 2 by the peeling of the sealing material 4. Specifically, the upper surface of the closing plate main body 31 of the closing plate 3 is lifted above the upper opening edge 22 b of the inner plug body 22.

  The lid 5 has a top wall seal portion 51 for pushing the closing plate 3 lifted toward the outside of the container main body 2 toward the inside of the container main body 2 as shown in FIG. Close openable. Since the closing plate 3 is elastically displaced (retracted) to the inside (specifically, the lower side than the upper opening edge 22b of the inner plug body 22) by the sealing member 4, the sealing member 4 is peeled off. However, even if the sealing material 4 is heat-sealed or the like, there is no possibility of deformation due to the influence thereof. Therefore, the flatness of the closing plate 3 is high, and by setting such closing plate 3 as a sealing surface, high sealing performance can be ensured even after the sealing material 4 is peeled off.

  As shown in FIG. 2, the top wall seal portion 51 has a smooth pressing surface 53 that presses the radially outer side of the discharge port 31 a on the upper surface of the closing plate 3 over the entire circumference. According to this configuration, since the radially outer side of the discharge port 31a on the upper surface of the closing plate 3 is pressed over the entire circumference by the smooth pressing surface 53 of the top wall seal portion 51, high sealing performance is ensured. Can. Further, since the closing plate main body 31 can be elastically displaced by the connecting portion 33, the closing plate main body 31 is elastically displaced so as to follow the smooth pressing surface 53 by the pressing of the top wall sealing portion 51. In order to enhance the adhesion with the pressing surface 53 of the portion 51, higher sealing performance can be ensured.

  Moreover, the discharge port 31a formed in the closure plate main body 31 is equipped with a slit-like valve. According to this configuration, when the container body 2 is compressed by the force of the finger, the valve is pushed open and a small amount of content is discharged, and when the force of the finger is released, the valve is pushed back by the atmospheric pressure and the discharge port 31a To shut off the air flow inside and outside the container body 2 so that the contents can be stored for a long time without deterioration. Therefore, the discharge container 1 can be made to be free from liquid shortage. In addition, when the slit is closed after the discharge of the contents, the contents outside the discharge port 31a and the contents inside the discharge port 31a are separated, so that the liquid drainage property is further improved. In addition, once such a slit-like valve starts to be used and stored for a long time without being used, elastic synthetic resins constituting the valve adhere to each other during that time, and the valve becomes smooth in the next use. It may not open and close. Such adhesion is particularly likely to occur when the material is silicone rubber. Therefore, by providing the protrusion 31b on the upper surface of the closing plate main body 31, the protrusion 31b is pressed to the inside of the container main body 2 by the top wall seal portion 51 in the closed state shown in FIG. It is in a state of In this way, it is possible to prevent the contents from drying out and closing the slit so as to be unopenable in a state where the slit is closed.

  The container body 2 includes an inner container 10 which is reduced in volume as its contents decrease, and an outer container 11 in which the inner container 10 is internally provided and an intake hole 14 for suctioning the outside air between the inner container 10 is provided. It has the lamination peeling type container 12 which has. According to this configuration, after pressing the laminated peeling container 12 to discharge the contents, when the pushing of the laminated peeling container 12 is released, the discharge valve 24 faces the inside of the inner container 10 from the discharge port 31a. Inflow of contents and outside air is prevented, and outside air is introduced between the outer vessel 11 and the inner vessel 10 from the intake hole 14 provided in the outer vessel 11 to reduce the volume deformation of the inner vessel 10 while the outer vessel is introduced. 11 can be restored to the original shape, so that the contents are discharged without being replaced with the outside air, whereby the contents remaining inside the laminate peeling type container 12 are difficult to contact with the air to deteriorate or deteriorate the contents. Can be suppressed.

  In addition, the inner plug member 20 is disposed at the upper end opening edge of the opening 12 a of the laminated peelable container 12, and the inner plug member 20 has a bottomed cylindrical inner plug body 22 and a bottom wall of the inner plug body 22. It has a communicating hole 23 formed in the portion 22a and communicating the discharge port 31a with the inner side of the inner container 10, and a discharge valve 24 closing the communicating hole 23 in an openable manner. Since the sealing material 4 is releasably adhered to the upper end opening edge 22b of the inner plug body 22, peeling of the sealing material 4 does not damage the inner container 10.

  In addition, the closing plate 3 closes the upper end opening 22A of the inner plug body 22, and the content storage capable of storing contents between the closing plate 3 and the discharge valve 24 inside the inner plug body 22. A space 80 is formed. According to this configuration, since the contents can be stored in the contents storage space 80 formed inside the inside plug body 22 and the filling seal by the contents can be formed, the outside air from the discharge port 31a to the inside of the inner container 10 Can be suppressed. In particular, in the case of containing relatively high-viscosity contents including some solid matter such as sauce, miso, ketchup and mayonnaise, some kind of force toward the inside of the container body 2 with respect to the closing plate 3 Since the content having such a high viscosity is accommodated and the closing plate 3 is supported from below, the closing plate 3 is difficult to separate from the ceiling seal portion 51, and the sealing property is further enhanced. It can be secured. Moreover, since the contents having a high viscosity are unlikely to leak from the discharge port 31a even if the container body 2 is inverted, high sealing performance can be ensured in this sense as well. The viscosity of the preferable content which exhibits such an effect is 500 mPa * s or more, for example, More preferably, it is 1000 mPa * s or more.

It is arranged.

  The closing plate main body 31 is connected to the upper end portion of the connecting peripheral wall portion 35, and can be elastically displaced to the inside and the outside of the container main body 2. Specifically, as shown by the solid line in FIG. 5, the closing plate main body 31 is elastically displaceable inside the container main body 2 which is lower than the upper opening edge 49a of the nozzle portion 49. Further, as shown by the two-dot chain line in FIG. 5, the closing plate main body 31 can be elastically displaced to the outside of the container main body 2 above the upper opening edge 49 a of the nozzle portion 49. The closing plate main body 31 is formed in an inverted dome shape (see FIG. 6), and a slit-like discharge port 31a is formed at the center thereof.

  As shown in FIG. 5, the seal member 4 is releasably adhered to the container body 2A, and elastically displaces the closing plate 3 toward the inside of the container body 2A. The sealing material 4 is releasably adhered to the upper end opening edge 49 a of the nozzle portion 49 by heat fusion. The seal member 4 is provided with a pick portion 4a extending, and it is possible to peel off the seal member 4 from the upper end opening edge 49a of the nozzle portion 49 by pulling up the pick portion 4a picked with a finger. .

  The lid portion 41A includes a peripheral wall portion 50 connected to the mounting cylindrical portion 40A via the hinge portion 42, and a top wall portion 54 connected to an upper end portion of the peripheral wall portion 50. The top wall portion 54 includes a push-in portion 55, a seal pressing portion 56, and a sealing peripheral wall portion 57 (seal portion). The push-in portion 55 has a substantially hemispherical shape projecting downward from the center of the lower surface of the top wall portion 54, and is disposed coaxially with the container axis O.

  The lower end portion of the push-in portion 55 is disposed below the upper end opening edge 49a of the nozzle portion 49, and as shown in FIG. 6, the closing plate 3 restored and displaced by peeling of the sealing material 4 is the container main body 2A. It is designed to be pushed inward. The lower end portion of the pushing portion 55 abuts radially inward of the discharge port 31 a on the upper surface of the closing plate 3. That is, the push-in portion 55 opens the discharge port 31a (slit) when the lid portion 41 is closed, and does not close (seal) the discharge port 31a.

  The seal pressing portion 56 is disposed coaxially with the container axis O outside the push-in portion 55 in the lower surface of the top wall portion 54 in the radial direction. The seal pressing portion 56 has a cylindrical shape projecting downward from the lower surface of the top wall portion 54 along the direction of the container axis O, and is adhered to the upper opening edge 49a of the nozzle portion 49 as shown in FIG. The seal member 4 is pressed from above.

  The sealing peripheral wall portion 57 is disposed coaxially with the container axis O outside the seal pressing portion 56 on the lower surface of the top wall portion 54 in the radial direction. The sealing peripheral wall portion 57 has a cylindrical shape projecting downward from the lower surface of the top wall portion 54 along the direction of the container axis O, and is in close contact with the outer peripheral surface of the lower end portion of the nozzle portion 49 as shown in FIG. The discharge port 31a is closed (sealed).

  In the discharge container 1A configured as described above, when discharging the contents, first, the lid portion 41A is pivoted upward around the hinge portion 42. In addition, when the sealing material 4 adheres to the container main body 2A, the sealing material 4 is peeled off from the container main body 2A by pulling up the pick part 4a. When the sealing material 4 is peeled off, the closing plate 3A elastically displaced toward the inside of the container body 2A by the sealing material 4 is restored and displaced toward the outside of the container body 2A. After that, for example, the container body 2A is squeezed (elastically deformed) while being tilted or turned upside down.

  As a result, the internal pressure of the container body 2A is increased, and the slit of the discharge port 31a is opened, whereby the contents are discharged from the discharge port 31a to the outside. When the squeeze deformation of the container body 2A is stopped or released, the rise of the internal pressure of the container body 2A is stopped or the internal pressure of the container body 2A is decreased, and the slit of the discharge port 31a is closed. For this reason, discharge of the content is stopped. When the discharge of the contents from the discharge container 1A is finished, the cover 41A of the cover 5 is rotated about the hinge 42, and the engagement convex 45 on the mounting cylinder 40A and the engagement concave on the cover 41A are made. Engage with 52.

  Then, as shown in FIG. 6, the lid 41 </ b> A is in a closed state in which the closing plate 3 </ b> A is covered. In this closed state, the push-in portion 55 provided on the top wall portion 54 of the lid portion 41A pushes the closing plate 3A, which has been restored and displaced due to peeling of the sealing material 4, toward the inside of the container body 2A. The slit of the outlet 31a is in an open state. In this way, it is possible to prevent the contents from drying out and closing the slit so as to be unopenable in a state where the slit is closed. For this reason, even if it is stored without being used for a long time after it has been used, the elastic synthetic resins constituting the valve do not adhere to each other, and the valve opens and closes smoothly in the next use. become.

  Further, in the closed state, the sealing peripheral wall portion 57 provided on the top wall portion 54 of the lid portion 41A abuts on the outer peripheral surface of the lower end portion of the nozzle portion 49, thereby closing the radially outer side of the discharge port 31a. Do. Thereby, the contents can be prevented from leaking from the discharge port 31 a to the outside in the radial direction more than the sealing peripheral wall portion 57.

  As described above, according to the discharge container 1A according to the second embodiment, when the sealing material 4 adhered to the container main body 2A is peeled off, as shown in FIG. 5, the sealing material 4 faces the inside of the container main body 2A. The closure plate 3A, which has been elastically displaced, is restored and displaced toward the outside of the container body 2A as shown in FIG. Since the closing plate 3A is elastically displaced (retracted) to the inside (specifically, the lower side than the upper end opening edge 49a of the nozzle portion 49) of the container body 2A by the sealing member 4, the sealing member 4 is peeled off. Also, a part thereof does not remain, and even when the sealing material 4 is heat-sealed, it is not deformed by the influence. For this reason, even after peeling off the sealing material 4, high sealing performance can be ensured.

Third Embodiment
Next, a discharge container according to a second embodiment of the present invention will be described. In the following description, the same or equivalent components as or to those of the embodiment described above are designated by the same reference numerals, any explanation of which will be simplified or omitted.

The configuration other than the diaphragm unit 58 is the same as the configuration of the second embodiment described above.

  The throttling portion 58 protrudes downward from the lower surface of the top wall portion 54 along the direction of the container axis O, and is arranged coaxially with the container axis O. The lower end portion of the throttling portion 58 is disposed above the upper end opening edge 49 a of the nozzle portion 49 and below the radially outer end edge of the closing plate main body 31 in the restored state or the upper end portion of the connecting circumferential wall portion 35 There is. The radially inner shape of the constricted portion 58 inclines inward in the radial direction from the lower end toward the upper side. If the inclination of the throttling portion 58 can come in contact with the radially outer end edge of the closing plate main body 31 or the upper end portion of the connecting circumferential wall portion 35 from the radially outer side, the throttling portion 58 has a cylindrical or circumferential gap It may be a plurality of projections with a gap.

  According to the third embodiment of the above configuration, by narrowing the upper end portion of the radially outer end edge or the connection circumferential wall portion 35 of the reverse dome-shaped closing plate main body 31 toward the radially inner side by the narrowed portion 58, As shown in FIG. 7, the closing plate 3A restored and displaced due to the peeling of the sealing material 4 can be pushed toward the inside of the container body 2A, and the slit of the discharge port 31a can be opened. According to this configuration, as shown in FIG. 5, it is not necessary to cause the push-in portion 55 to protrude below the upper end opening edge 49a of the nozzle portion 49, so the amount of push-in of the seal material 4 is reduced. The load applied to 4 can be reduced, and the tearing of the sealing material 4 can be prevented.
