  Although the above-described dispensing container has a function of blocking the outside air at the covering portion and the portion of the dispensing valve body, the outside air blocking mechanism is composed of a large number of functional members, and the structure is complicated. Cost becomes high. Further, since the structure is complicated, the shape has to be increased to some extent, and it is difficult to use it for a small-diameter mouth portion of a general general-purpose product, and there is a problem that the general-purpose property is lacking.

  The present invention has been made by paying attention to the above-described problems, and has a blocking function capable of reliably preventing the outside air from flowing into the housing portion when the structure is simple and the contained material is poured out. It aims at providing the container which has.

  In order to achieve the above-described object, a container according to the present invention includes a container part in which a container is accommodated, a mouth part having a pouring channel through which the container is poured out, and the mouth part. And an outside air blocking member having a welded portion having a substantially boat-shaped cross section. The outside air blocking member is integrally formed with the welded portion and communicates with the pouring channel. A tube part and a nozzle part in which a cavity part and a contact part are formed above the cylinder part, while forming a contact area on a side surface of the cylinder part by welding the sheet-like member to the weld part. And an outflow port for allowing the contents to flow out from the extraction flow path to the cavity portion is formed in the close contact region of the cylindrical portion, cutting the tip of the nozzle portion, and By applying a pressing force, the close contact state of the sheet-like member with respect to the outlet is released, and the front Via the contact portion and the hollow portion, characterized in that the housing was possible dispensing.

  In the container having the above-described structure, when the tip of the nozzle portion is cut and a pressing force is applied to the container to increase the internal pressure, the container is removed from the outlet flow passage at the mouth of the container. The sheet-like member that is in close contact with the outlet of the tube portion of the tube is spread and flows into the cavity of the nozzle portion (non-contact portion where the inner surface of the sheet-like member is not in close contact), and further, the contact portion of the nozzle portion (sheet-like member) The portion where the inner surfaces of the nozzles are brought into close contact with each other by a tensile force is spread out and poured out from the tip of the nozzle portion. When the pressing of the storage portion is released, the stored matter is stored in the cavity portion of the nozzle portion, and the close contact portion after that is restored to the tensile force and comes into close contact again. In this case, the close contact portion is in a state in which the sealing film of the accommodation is formed by capillary force, and together with the accommodation stored in the cavity, the outside air is prevented from entering the housing side from the outlet. Demonstrates the sealing function. Moreover, since the sheet-like member is brought into close contact with the outlet of the cylinder portion again by the negative pressure, a reliable sealing function is exhibited.

  According to the container having the structure described above, the outside air blocking member is formed by the welded portion, the cylindrical portion integrally formed with the welded portion and having the outlet, the bag-like sheet-like member welded to the welded portion, and the like. Since it is configured, the structure is extremely simple, and it can be used for a small-diameter mouth portion of a general-purpose product.

  In order to achieve the above-described object, a container according to the present invention includes a container part in which a container is accommodated, a mouth part having a pouring channel through which the container is poured out, and the mouth part. And an outside air blocking member having a fixed portion, and the outside air blocking member is formed integrally with the fixed portion, communicates with the pouring channel, and forms a discharge port. And fixing a deformable close contact member with the fixing portion interposed therebetween, thereby forming a close contact region on a side surface of the tubular portion, and the tubular portion is within the range of the close contact region. The first partition chamber having a partition that divides the interior into two partition chambers, which is partitioned by the partition wall, communicates with the extraction flow path and has an outlet for discharging the contents. The second compartment having a close contact area and partitioned by the partition wall is formed of the cylinder And having an inflow port in the close contact area for receiving the contents poured out from the outflow port through the close contact area, and applying a pressing force to the storage portion. Thus, the close contact state of the close contact member with respect to the outflow port and the inflow port is opened, and the contents can be poured out through the discharge port of the cylindrical portion.

  In the container having the structure described above, when the internal pressure is increased by applying a pressing force to the container in a state where the discharge port of the cylinder is opened, the container is brought into close contact with the first compartment of the cylinder. The adhesive member that is in close contact is pushed out and the inflow portion of the close contact region is opened. That is, the contents flow out through the outlet opened from the first compartment, and the space between the contact member whose contact state is released and the side surface of the cylindrical portion (the contact member is pushed and expanded). It flows into the second compartment from the inflow port via a flow path for the contained material formed between the outlet and the inflow port, and is poured out through the discharge port. Then, when the pressing of the housing portion is released, the tensile force of the contact member is restored by the negative pressure, and the contact member in the contact region comes into close contact with the side surface of the cylindrical portion again to close the outlet and the inlet. Accordingly, it is possible to prevent the outside air from flowing into the housing part after the contained material is poured out, and a reliable sealing function is exhibited.

  Further, in the container having the above-described structure, the container is isolated from the outside by the partition wall of the cylindrical part, and is further isolated from the outside by the contact area between the outlet and the inlet and the contact member. That is, since the container is in a state isolated from the outside in two stages, the sealing performance after the container is poured out can be improved, and the leakage of the container after the container is poured out can be prevented. . In addition, the exhaust opening opened to the outside also ensures a suck back effect (the effect that the stored matter is sucked into the storage portion by the pressure difference with the outside air when the outlet and the inlet are closed). Resealability and leakage resistance are ensured. In the above-described structure, the outside air blocking member has only a partition wall in the cylindrical portion to form the outlet and the inlet, and it is only necessary to fix the contact member to the fixing portion. It can also be used for small-diameter mouth portions of general-purpose products.

  ADVANTAGE OF THE INVENTION According to this invention, when a structure is simple and pours out an accommodation thing, the accommodation body which can prevent reliably that external air flows in into an accommodating part is obtained.

FIG. 3 is a perspective view of an outside air blocking member, FIG. 3 is a view showing an outflow path of the stored item when the tip of the nozzle portion is cut and the stored item is poured out, and FIG. FIG. 4B is an enlarged sectional view showing a sealed state, and FIG. 4C is an enlarged sectional view showing a dispensing state.

  In the container 1 according to the present embodiment, a container 2 in which a container of liquid (for example, food, medicine, cosmetic liquid, ink, etc.) is stored, and a container stored in the container 2 are poured out. The mouth 3 is provided with an extraction flow path 3a, and the outside air blocking member 10 is attached to the mouth 3 and has an outside air blocking function for the housing 2.

  The housing portion 2 of the housing body 1 may be formed of a flexible member and may be configured so that the stored material can be discharged by applying a pressing force from the outside. For example, as illustrated in FIG. It is formed into a bottle shape. In addition, about a storage part, what is necessary is just a form which can pour out a stored item when a pressing force is given, and it comprises a bag body which welded an edge of a soft lamination sheet like a 2nd embodiment mentioned below. May be.

  The mouth portion 3 is formed in a cylindrical shape projecting from the surface of the housing portion in the central region of the upper end of the housing portion 2, and a screw portion 3b is formed on the outer peripheral surface thereof. A cap 10A that is screwed with the screw portion 3b is detachably attached to the projecting mouth portion 3. In this embodiment, the outside air blocking member 10 is integrally formed on the upper surface of the cap 10A. Is provided. In addition, about the opening | mouth part 3, as long as it has the shape where the accommodation thing from the accommodating part 2 is distribute | circulated and an external air blocking member is mounted | worn, it does not necessarily protrude from an accommodating part as shown in a figure. good. Further, the outside air blocking member 10 may be fixed without being attached to or detached from such a mouth portion 3.

  The outside air blocking member 10 and the cap 10A are integrally formed of a synthetic resin such as polyethylene or polypropylene, for example. The main body 11 of the outside air blocking member 10 has a welded portion 13 to which the stacked sheet members 12a and 12b are welded. The welded portion 13 may be interposed between the stacked sheet-like members 12a and 12b so that the inner edge of the welded portion 13 is easily welded. For example, the cross section has a boat shape, an elliptical shape, a circular shape. Such shapes are applicable (these shapes are substantially boat-shaped). Then, the overlapped sheet-like members 12a and 12b are welded to the welded portion 13 interposed between the sheet-like members 12a and 12b by a heat bar (not shown) (the welded portions are indicated by hatching).

  The main body 11 is integrally formed with the welded portion 13 with a bottomed portion (corresponding to the upper end wall 13a) that communicates with the pouring channel 3a. In this case, the cylindrical portion 13A corresponds to a portion of the welded portion 13 where the sheet-like members 12a and 12b are not welded, and the sheet-like members 12a and 12b are in close contact with each other by the tensile force. Yes. For this reason, the surface of the cylinder portion 13A may be flush with the surface of the weld portion 13 (substantially boat-shaped in cross section) or may be a stepped surface. That is, the cylindrical portion 13A and the welded portion 13 are integrated, a portion where the sheet-like members 12a and 12b are welded (portion indicated by hatching) becomes the welded portion 13, and an unwelded portion (outlined portion) is the cylindrical portion. 13A is constituted. In the present embodiment, the surface of the cylindrical portion 13A is a stepped surface that is recessed from the surface of the welded portion 13, and both end portions of the welded portion 13 are protruding edges that protrude outward from the outer surface of the cylindrical portion 13A. 13f.

  The insides of the welded portion 13 and the cylindrical portion 13A are hollow, and a flow path 15 (see FIG. 4) communicating with the extraction flow path 3a of the mouth portion 3 is formed. The flow path 15 is closed by an upper end wall (bottom part) 13a of the cylindrical portion 13A, and is partitioned from a discharge flow path of a nozzle portion described later. Note that the upper end wall 13a may be formed in a flat shape, or may be bulged in a dome shape as shown in the drawing in consideration of sink marks during thermoforming.

  The sheet-like members 12 a and 12 b are welded in a bag shape, and the inner surface of the opening end thereof is welded to the welded portion 13 to constitute the nozzle portion 12. In the present embodiment, the three regions (side edges 12e, 12f and the top portion 12g) of the nozzle portion 12 are welded together with the weld portion 13 by a heat bar, and the above-described regions are overlapped with the sheet-like members 12a, 12b being overlapped. The nozzle part 12 is formed by welding integrally. Note that the opening of the sheet-like member that has been formed into a bag shape in advance may be welded to the welded portion 13.

  In this case, the welded portion 13 of the main body 11 has a cavity portion R1 (portion shown in white) and a close contact portion R2 in the extraction flow path 12A of the nozzle portion in relation to the nozzle portion 12 formed in the bag shape. It is only necessary to have a shape in which (a portion indicated by oblique lines) is formed. That is, such a hollow portion R1 can be generated on the proximal end side of the pouring channel 12A because the welded portion 13 swells (thickness in a direction perpendicular to the channel 15), and the nozzle portion This is a region (hollow portion) where the inner surfaces of 12 do not adhere to each other. And the pouring flow path 12A above the hollow portion R1 is brought into close contact with each other by tensile force due to the welding of the side edges 12e, 12f and the top portion 12g, and the close contact portion R2 (the portion indicated by the oblique lines). Will come to form. Further, a break line C is formed on the tip end side of the nozzle portion 12 so as to cross the contact portion R2.

  The size of the hollow portion R1 can be variously changed depending on the shape of the nozzle portion 12, the material of the sheet-like members 12a and 12b, the flow channel width, the flow channel length, the degree of swelling of the welded portion 13, and the like. Is possible. Further, the close contact portion R2 is a portion that exhibits a sealing effect (outside air blocking effect) described later, and the seal effect is determined by the length of the close contact portion R2, so that the nozzle portion 12 as in the present embodiment. The shape of the nozzle portion 12 may be a straight line, and in particular, it is not necessary to provide a deformed portion, a bent portion, or the like (of course, the shape of the nozzle portion 12 may be deformed according to the use application).

  The cylindrical portion 13A is formed with an outlet 18 through which the contents are discharged from the channel 15 to the extraction channel 12A of the nozzle portion 12 (in this embodiment, the outlet 18 is the outlet of the cylindrical portion 13A). It is formed in two places on both sides). The outlet 18 is formed in a region (non-weld region) where the sheet-like members 12a and 12b are in close contact with each other, and is normally sealed by the elastic force (tensile force) of the sheet-like members 12a and 12b. It has become so.

  In this case, as shown in FIG. 4, the outlet 18 of the present embodiment is formed in a convex portion 18 </ b> A that protrudes from the surface of the cylindrical portion 13 </ b> A, and thereby the sheet-like member 12 a that acts on the outlet 18. The sealing force is improved by increasing the tensile force of 12b. That is, as shown in FIGS. 4A and 4B, on the surface (unwelded region) of the cylindrical portion 13A, the sheet-like members 12a and 12b are in pressure contact with the tip surface of the convex portion 18A by the tensile force, The outlet 18 is closed. Then, in this closed state, when a pressing force is applied to the housing portion 2 to increase the internal pressure on the housing portion 2, as shown in FIG. It is possible to guide the nozzles 12 by letting the contents flow out. In addition, although the above-mentioned convex part protruded perpendicularly | vertically from the surface of 13 A of cylinder parts, you may gradually thicken the area | region in which the outflow port 18 is formed, for example. In such a configuration, a region where the sheet-like member is closely attached at the time of sealing becomes wider, and the sealing effect can be enhanced.

The operation of the container 1 configured as described above will be described.
As shown in FIG. 3, after cutting the fracture line C at the tip of the nozzle portion 12, the container is pressed against the container 2 to increase the internal pressure, whereby the container is discharged from the outlet 3. As shown by the arrow in FIG. 4C, the sheet-like member in a close contact state is spread out from the flow path 15 and flows out into the extraction flow path 12A of the nozzle section 12 along the surface of the cylinder section 13A. (See arrow in FIG. 3). In this case, the nozzle portion 12 is formed with a cavity portion (non-contact portion where the inner surfaces of the sheet-like members are not in close contact) R1 and a contact portion (portion where the inner surfaces are in close contact with each other by a tensile force) R2. And by pressing the accommodating part 2 and raising an internal pressure, the accommodated thing moves so that the contact | adherence part R2 may be expanded from cavity part R1, and comes to be poured out from the part cut | disconnected. Further, by changing the pressing force with respect to the housing portion 2, the discharge width at the contact portion R2 can be automatically changed according to the pressing force.

  In addition, since the nozzle part 12 can be easily inserted in the opening part of another storage container at the time of the above-mentioned extraction | pouring operation, it becomes possible to perform the refilling operation | work of a stored material easily.

  When the pressing force applied to the storage portion 2 is released after the operation of pouring the storage material, the storage material is stored as it is in the hollow portion R1 of the nozzle portion 12, and the adhesion portion R2 ahead of the storage portion 2 has a tensile force. Recovers and comes into close contact again. In this case, the close contact portion R2 is in a state in which the sealed film of the contained material is formed by the capillary force, and the outside air is prevented from entering the containing portion together with the contained material stored in the cavity portion R1, and the sealing effect is achieved. Demonstrate (outside air blocking effect). Moreover, as the pressing force of the accommodating portion 2 is released, the sheet-like member that has been spread as shown in FIG. 4C is shown in FIG. 4B due to its tensile force and negative pressure. In addition, since the surface closely contacts the surface of the convex portion 18A, the sealing effect on the housing portion side is reliably maintained.

  The container 1 configured as described above can integrally form the outside air blocking member 10 attached to the mouth portion 3 with a simple mold, and the sheet-like member can be formed into a predetermined portion by a heat bar. Since it can be created simply by welding, the structure becomes very simple, and it can be used for a small-diameter mouth portion of a general general-purpose product. In addition, as shown in FIG. 3, the outside air blocking member 10 of the present embodiment is configured to be detachable with respect to the mouth portion 3, so that versatility is enhanced and the storage portion 2 can be reused. It becomes possible.

  Since the sealing effect of the outside air blocking member 10 in the above-described embodiment can be achieved by the accommodation stored in the cavity R1 of the nozzle portion 12 and the close contact at the close contact portion R2, the outlet 18 is It can be modified as appropriate. For example, the outflow port 18 may be formed on the surface portion of the cylindrical portion without protruding, or may be formed on the above-described upper end wall 13a portion. In this case, with respect to the cavity R1 and the close contact portion R2 of the nozzle portion 12, a pressure flow is applied in a state where the accommodation is accommodated in the accommodation portion 2 to increase the internal pressure, thereby generating a flow path through which the accommodation flows out. In addition, when the pressing force is released and the internal pressure of the accommodating portion 2 is reduced, the tensile force is restored, the inner surfaces of the sheet-like members 12a and 12b are brought into close contact with each other, and the outside air is prevented from flowing into the accommodating portion. It only has to be set so that it can.

Next, a second embodiment of the container according to the present invention will be described with reference to FIGS.
In these drawings, FIG. 5 is a diagram showing the overall configuration, FIG. 6 is an enlarged view of the main part of the container shown in FIG. 5, a perspective view of the outside air blocking member, and FIG. FIG. 8 is a perspective view showing a state in which the plug member of the cylindrical portion is opened by opening the plug member, and the outlet flow path of the stored item when discharging the stored item; FIG. 9 is a partial cross-sectional view of the outlet portion of the cylindrical portion.

  The accommodating portion 22 is formed by overlapping sheet-shaped members 22a and 22b having a predetermined shape and welding peripheral edges (side edges 22e and 22f, an upper edge 22g and a lower edge 22h) indicated by oblique lines. In the present embodiment, when the lower edge 22h is welded, the bottom portion 22i is welded and is configured as a self-solid body. However, a non-self-solid body (two-body that is simply welded to the peripheral portions of the sheet-like members 22a and 22b) It may be configured as a rectangular parallelepiped, a trihedral, etc. That is, regarding the accommodating part 22, about the part to weld, the shape of the sheet-like member which comprises a bag, etc., it can change suitably according to a use application etc., and it is limited to the structure shown in a figure. Absent. Moreover, as a accommodating part, the bottle structure like the said 1st Embodiment may be sufficient.

  The sheet-like members 22a and 22b are made of a flexible synthetic resin sheet (plastic film), for example, polyethylene or polypropylene so as to be easily welded. It is composed of a so-called composite layer in which nylon, aluminum foil, etc. are laminated so as to enhance the properties.

  The mouth part 23 has a welded part 23c having a substantially boat-shaped cross section. The sheet part 22a, 22b is welded to the welded part 23c, so that the mouth part 23 protrudes from the accommodating part 22. (The mouth portion 23 is interposed and welded between the sheet-like members 22a and 22b).

  The mouth portion 23 is formed in a cylindrical shape protruding from the upper edge 22g of the accommodating portion 22, and a screw portion 23b is formed on the outer peripheral surface thereof. A cap 30A that is screwed with the screw portion 23b is detachably attached to the protruding mouth portion 23, and the outside air blocking member 30 is integrally formed on the upper surface of the cap 30A as in the above-described embodiment. Is provided.

  The main body 31 of the outside air blocking member 30 has a cross section so that a deformable close contact member (in this embodiment, constituted by the stacked sheet members 32a and 32b) is welded (fixed) on both upper and lower sides. It has welding parts (fixed parts) 33a and 33b having a substantially boat shape. Further, the main body 31 is integrally formed with a welded portion 33a, 33b with a cylindrical portion 33A communicating with the extraction channel 23a. In this case, the cylindrical portion 33A corresponds to a portion of the welded portions 33a and 33b where the sheet-like members 32a and 32b are not welded, and the sheet-like members 32a and 32b are in close contact with each other due to the tension. ing. For this reason, the surface of the cylindrical portion 33A may be flush with the surfaces of the welded portions 33a and 33b (substantially boat-shaped in cross section) or may be a stepped surface. That is, the cylindrical portion 33A and the welded portions 33a and 33b are integrated, the portions where the sheet-like members 32a and 32b are welded (hatched portions) become the welded portions 33a and 33b, and the unwelded portions (outlined portions) are. A cylindrical portion 33A is configured. In the present embodiment, the surface of the cylindrical portion 33A is flush with the surfaces of the welded portions 33a and 33b, and both end portions of the welded portions 33a and 33b protrude outward from the outer surface of the cylindrical portion 33A. A protruding edge 33f is formed. The sheet-like members 32a and 32b are welded to each other at both side edges 32f and 32g in addition to the welded portions 33a and 33b.

  The cylindrical portion 33A includes a partition wall 34 that divides the inside thereof into two upper and lower compartments 34A and 34B. In this case, in the present embodiment, the inside of the cylindrical portion 33A is partitioned vertically by the partition wall 34, but may be partitioned horizontally, and the partitioning direction is not particularly limited. In the present embodiment, the space to be partitioned is a cylindrical space, but a space having an arbitrary shape may be partitioned (the shape of the cylindrical portion is not limited to a cylinder).

  The cylindrical portion 33A (unwelded portion) is formed so as to straddle the upper and lower two compartments 34A and 34B, and the sheet-like members 32a and 32b are portions corresponding to the upper and lower two compartments 34A and 34B. The surface (cylinder part surface) is in close contact (or pressure-bonded).

  The lower first partition chamber 34 </ b> A partitioned by the partition wall 34 communicates with the pouring channel 23 a of the mouth portion 23 and has an outlet 37 for pouring the contents in the housing portion 22. In the present embodiment, two outlets (only one is shown) 37 are provided on both sides of the side surface of the cylindrical portion 33A, for example, 180 ° apart in the circumferential direction, but the number of outlets 37 is one. What is necessary is just to form above.

  The upper second compartment 34B partitioned by the partition wall 34 is opened to the outside through a discharge port 40 formed at the upper end of the cylindrical portion 33A, and poured out from the outlet 37 of the first compartment 34A. It has an inlet 38 for receiving the contents. In this embodiment, two inflow ports (only one is shown) 38 are provided at 180 ° circumferentially spaced apart on both sides of the side surface of the cylindrical portion while being substantially aligned with the corresponding outflow port 37 in the vertical direction. However, the number of the inflow ports 38 may be one or more.

  In the present embodiment, the outlet 37 and the inlet 38 are formed substantially flush with the side surface of the cylindrical portion 33A, but, like the first embodiment, protrudes radially outward from the side surface of the cylindrical portion 33A. It is also possible to provide a convex portion to be formed, and to form the outlet 37 and the inlet 38 on the convex portion. In that case, it is preferable to form the tip of the convex portion on a flat surface so that the inner surfaces of the sheet-like members 32a and 32b are in close contact with each other. In such a configuration, since the sheet-like members 32a and 32b are elastically stretched radially outward by the convex portions, the sheet-like members 32a and 32b are pulled on the front end surfaces of the convex portions in the close contact region. The outlet 37 and the inlet 38 can be closed in a sufficiently sealed state by pressing with force.

  The discharge port 40 formed at the end portion of the cylindrical portion 33A may be the one in which the end portion of the cylindrical portion 33A is opened as it is, or the end portion of the cylindrical portion 33A as shown in FIG. A weight-like reduced diameter portion 41 may be formed on the end of the reduced diameter portion 41. In addition, a removable plug member 45 may be attached to the discharge port 40. In this case, the plug member 45 includes a weight-like contact surface 45a that contacts the surface of the reduced diameter portion 41, and a fitting portion 45b that protrudes from the center of the contact surface 45a and fits into the discharge port 40. The plug member 45 is integrated with the end portion of the cylindrical portion 33A in a state where the discharge port 40 is closed in advance. That is, by cutting off and opening the plug member 45, the contents can be poured out, and after the pouring operation is performed, the discharge port 40 can be closed by the plug member 45.

The operation of the container 21 configured as described above will be described.
As shown in FIG. 7, after cutting off the plug member 45 attached to the discharge port portion of the cylindrical portion 33 </ b> A, by pressing the accommodating portion 22 of the accommodating body to increase the internal pressure, the contents in the accommodating portion 22 are 7 and 8, the sheet 23 flows into the lower first compartment 34A via the outlet flow passage 23a of the mouth 23 and is in close contact with the outlet 37. The members 32a and 32b are pressed. Then, by this pressing force, the sheet-like members 32a and 32b that are in close contact with the side surface of the cylindrical portion are separated (the sheet-like members 32a and 32b are spread), and the outlet 37 and the inlet 38 are opened.

  As a result, as shown by the arrows in FIGS. 7 and 8, the contents flow out from the first compartment 34 </ b> A through the opened outlet 37, and the sheet-like members 32 a and 32 b released from the close contact state. The inlet 38 through the space between the side surfaces of the cylindrical body (the flow path for the contents formed between the outlet 37 and the inlet 38 when the sheet-like members 32a and 32b are expanded). And flows into the upper second compartment 34 </ b> B and is poured out through the outlet 40. The contents at this time are filled in the compartments 34A and 34B, and the contents can be poured out in a drop shape as shown in FIG. This makes it possible to perform the dispensing operation while grasping the amount of dispensing.

  And if such a thing is poured out and the pressing force which acts on the accommodating part 22 is cancelled | released, it will become possible to store a thing as it is in the 2nd compartment 34B. At this time, since the pressing force acting on the sheet-like members 32a and 32b is released, as shown in FIG. 9, the sheet-like members 32a and 32b in the inflow port 38 (outlet port 37) have their negative pressure and tension. Since the force closes the side surface of the cylinder 33A again and closes the outlet 37 and the inlet 38, it is possible to reliably prevent the outside air from flowing into the housing portion 22. That is, a reliable sealing effect is obtained by the storage effect by the second compartment 34B and the adhesion effect by the sheet-like members 32a and 32b. Further, in the present embodiment, since the discharge port 40 of the cylindrical portion 33A is opened to the outside, the sucked back effect (the stored item is stored in the storage portion due to the pressure difference with the outside air when the outlet 37 and the inlet 38 are closed). The effect of being sucked toward the inside 22 is also obtained, and a reliable resealability can be obtained, and dripping can be reliably prevented.

  Moreover, in this embodiment, since the 2nd division chamber 34B by the side of a discharge port has the function (function to become a storage chamber) to store a storage thing after the outflow of a storage thing, whenever it discharges a storage thing In addition, it becomes possible to always store a certain amount of the stored item in the second compartment 34B, and a weighing function of the stored item can be obtained. In the present embodiment, the outlet 37 and the inlet 38 are formed on both sides of the side surface of the cylindrical portion 33A in a state where the outlet 37 and the inlet 38 are substantially aligned with each other. An outflow can be realized.

  The container 21 configured as described above can integrally form the outside air blocking member 30 attached to the mouth portion 23 with a simple mold, and the sheet-like member can be formed by a heat bar. Therefore, the structure is extremely simple and can be used for a small-diameter mouth portion of a general general-purpose product. Further, as shown in FIG. 6, the outside air blocking member 30 is configured to be detachable with respect to the mouth portion 23, so that versatility is enhanced and the accommodating portion 22 can be reused.

  FIG. 10 is a view showing a modification of the above-described second embodiment, wherein (a) is a perspective view of the outside air blocking member portion, and (b) is a view showing a modification of the contact member.

  In this modification, the deformable contact member that is attached to the tubular portion 33 </ b> A formed in the main body 31 of the outside air blocking member 30 is configured by the tubular body 50. Such a cylindrical body 50 can be formed of an elastically deformable material such as rubber, and is attached to the cylindrical portion 33A and then fixed to the fixing portions 33a and 33b integrated with the cylindrical portion 33A. Fixed. For this reason, about a fixed part, it is possible to make it circular shape, without being limited to a cross-sectional substantially boat shape. Further, the fixing portions 33a and 33b may be fixed by welding or adhesion, or may be fixed by the elastic force of the cylindrical body, as long as the cylindrical body 50 is attached and does not move. May be. In this case, the cylindrical portion 33A can be easily attached by the reduced diameter portion 41.

  Even in such a configuration, the same operational effects as those of the above-described embodiment can be obtained, and the cylindrical body 50 covers the cylindrical portion 33A in which the outlet 37 and the inlet 38 are formed, thereby improving the appearance. be able to. Further, by making the design the same as the outer surface of the cap 30A, the appearance can be further improved.

  About the cylindrical body 50 which comprises the above-mentioned close_contact | adherence member, as shown in FIG.10 (b) other than the structure shown to Fig.10 (a), the rectangular member (plate | board) which has elasticity like a synthetic resin It is also possible to form a cylindrical body as a whole by stacking the body 51) and fixing both end edges 52, 53 by adhesion or welding. In other words, as described above, when the pressing member is applied to the accommodating portion in a state of being attached to the cylindrical portion 33A, the outlet 37 and the inlet 38 are resisted against the tension (elastic force). If the outlet 37 and the inlet 38 can be sealed by the tension when the pressure is released and the pressing force is released, the configuration and shape can be appropriately modified.
