The shape and arrangement of the intake valve element film 38 are not limited to a specific one, and it is sufficient that at least the intake passage 33 can be opened and closed.

The intake valve 75 opens and closes when the intake valve body film 38 moves up and down due to a pressure difference between the space 20 between the inner container 11 and the outer container 21 and the outside air. The intake valve 75 prevents the outflow of air from the space 20 between the inner container 11 and the outer container 21 when the outer container 21 contracts, and allows the outside air to flow between the inner container 11 and the outer container 21 when the shape of the outer container 21 is restored. It introduces into the space part 20 between. The intake valve 75 only needs to be able to prevent the outflow of air to the extent that the contents can be discharged from the inner container 11 when the outer container 21 contracts, and some leakage is allowed.

The cap 40 includes a cap body 41 attached to the mouth portion 13 of the spout 12, a base 51 having a valve hole 52 and attached by being press-fitted into the cap body 41, and an upper surface of the base 51 so as to cover the valve hole 52.

A cap 49 with a hinge that opens and closes the spout 42 is formed at the top of the cap body 41. The cap body 41 is not limited to a cylindrical body, and may be, for example, a rectangular tube or the like, and the shape can be determined in consideration of the shape or design of the spout 12 or the ring cap 31.

The material of the cap body 41 is not limited to a specific material, and examples of the material include synthetic resin materials such as polyethylene, metals, glass, carbon materials, sintered materials, and wood, and these composite materials Alternatively, it can be formed of a material appropriately selected according to the use, contents, etc., such as a material whose surface is coated with metal by vapor deposition, coating, plating, metal foil, or the like. For example, in order to prevent oxygen from entering the inner container 11 through the cap body 41, the cap body is made of plastic, composite material, laminated material, or other material having excellent oxygen barrier properties and air barrier properties, like the inner container 11 and the like. 41 may be formed.

The shape of the spout 42 is not limited to a specific shape, and can be determined as appropriate in consideration of ease of pouring and design. Further, when the spout 42 is disposed on the opposite side of the center of the valve hole 52 of the base 51 when the base 51 is attached to the cap body 41, the contents mixed in when filling the contents, etc. The air or gas in the vessel 11 is preferably discharged to the outside because it moves toward the valve hole 52 when the contents are poured out by tilting the dispensing container 1. However, it is not limited to this.

The pressing surface 44 is a lower surface of a step formed on the peripheral edge of the ceiling surface 43, and the pressing surface 44 is formed with a convex sealing means 45 over the entire circumference. When the base 51 is attached to the cap main body 41, the sealing means 45 seals in close contact with the upper surfaces of the base 51 and the film 61. If the pressing surface 44 and the upper surface of the base 51 and the film 61 can be brought into close contact with each other without using the sealing means 45 and sufficient sealing can be performed, the sealing means 45 may not be provided.

When the cap 40 is attached to the mouth portion 13 of the spout 12, the stopper 48 abuts on the periphery of the insertion opening 32 on the top surface of the ring cap 31, and the ring cap 31 is formed by the stopper 48 and the upper flange 15 of the spout 12. And the intake valve body film 38 are sandwiched. As a result, the inner container 11 and the intake valve body film 38 are fixed to the outer container 21 via the ring cap 31.

The position of the stopper 48 (the height of the cylindrical portion of the cap body 41) is such that when the cap 40 is attached to the mouth portion 13 of the spout 12, the upper flange of the spout 12 from the contact surface of the stopper 48 with the ring cap 31. 15 is determined to be substantially the same as the top of the ring cap 31 and the thickness of the intake valve body film 38 (substantially the same includes the same, hereinafter the same). The shape of the stopper 48 may be determined as appropriate in accordance with the shape of the portion where the ring cap 31 abuts.

The base 51 has a shape in which a ring-shaped seal cylinder 53 is formed from the lower surface of the disc body, and includes a valve hole 52 serving as an inlet of the discharge valve 71 in the disc portion. The base 51 is formed so that its diameter is slightly larger than the inner diameter of the cylindrical portion of the cap main body 41 so as not to come off after being attached to the cap main body 41, and is press-fitted into the cylindrical portion of the cap main body 41.

The material of the base 51 is not limited to a specific material. Examples of the material include synthetic resin materials such as polyethylene, metal, glass, carbon material, sintered material, wood, and the like. Alternatively, it can be formed of a material appropriately selected according to the use, contents, etc., such as a material whose surface is coated with metal by vapor deposition, coating, plating, metal foil, or the like. For example, in order to prevent oxygen from entering the inner container 11 through the base 51, the base is made of plastic, composite material, laminated material, or other material having excellent oxygen barrier properties and air barrier properties, like the inner container 11. 51 may be formed.

The valve hole 52 is drilled so as to be disposed at one or more locations in the disc portion and on the inner side (near the center portion) than the seal cylinder 53. The shape, size, and number of the valve holes 52 are not limited to specific ones. The size of the spout 42 of the cap body 41, the size of the discharge port 72 of the discharge valve 71, which will be described later, It is determined according to the type (viscosity). In addition, in the adhesion step S2 for bringing the base 51 and the film 61 into close contact, which will be described later, when the suction means is used, the suction points of the film 61 are dispersed by increasing the number of valve holes 52, and the film 61 is more reliably attached. It is possible to prevent wrinkles.

The seal cylinder 53 is formed in a ring shape from the lower surface of the base 51. When the cap 40 is attached to the mouth portion 13 of the spout 12, the seal tube 53 is in close contact with the inner peripheral surface of the mouth portion 13 of the spout 12. Seal. The shape of the seal cylinder 53 is not limited to a specific shape.

Further, instead of the seal cylinder 53, a convex protrusion (not shown) or the like that abuts on the front end surface of the mouth portion 13 of the spout 12 may be formed on the lower surface of the base 51 for sealing. If the lower surface of 51 and the front end surface of the mouth portion 13 of the spout 12 are in close contact and can be sufficiently sealed, it is not necessary to provide a sealing means such as the seal cylinder 53.

The film 61 is a thin film and includes a thin film having flexibility, flexibility and stretchability. The thickness of the film 61 is not particularly limited, and can be appropriately selected and used according to the application, contents, material, and the like. However, it is preferable that the film 61 is thin from the viewpoint of sealing performance between the upper surface of the film 61 and the base 51 and the sealing means 45 of the cap body 41. In this case, it is needless to say that the film 61 functions as a valve body of the discharge valve 71 and does not need to be damaged when contacting the sealing means 45 of the cap body 41. As an example of the thickness of the film 61, when the content is a liquid having a relatively low viscosity such as soy sauce (general soy sauce), it is about 20 to 30 μm with a polyethylene film. However, it is not limited to this value.

As a material of the film 61, a synthetic resin film such as polyethylene, a synthetic resin stretch film, a thin metal film having flexibility and / or flexibility, a carbon film, a glass film, etc. However, the film 61 is not limited to a specific material, and can be appropriately selected and used according to the application, contents, and the like. For example, in order to prevent oxygen from entering the inner container 11 through the film 61, plastics, composite materials, laminated materials and other materials having excellent oxygen barrier properties and air barrier properties can be used as in the case of the inner container 11 and the like. Good. When oxygen barrier properties and water vapor barrier properties are required at the same time, a multilayer film of a synthetic resin material that prevents air from entering and exiting and a synthetic resin material that prevents drying due to evaporation of moisture, and other oxygen barrier properties and water vapor barrier properties. Plastics, composite materials, laminated materials, etc. that are excellent in properties can be suitably used. However, since the film 61 is in a thin film shape, it is easier for gas to pass through compared to the inner container 11 or the like, so it is necessary to select a material in consideration of this point.

The film 61 has an arcuate partial circular shape having substantially the same diameter as the upper surface of the base 51, and covers the valve hole 52 when the outer edges of the arc portions are overlapped with the upper surface of the base 51. In addition, a linear end portion serving as a discharge port 72 described later is formed in such a size as to be located on the inner side (near the center portion) of the sealing means 45 of the cap body 41.

The shape and arrangement of the film 61 are not limited to specific ones. The valve hole 52 is covered with the upper surface of the base 51 and the sealing means 45 of the cap body 41 so that the valve hole 52 can be opened and closed. Any shape and arrangement may be used as long as the discharge port 72 is located on the inner side (closer to the center) than the sealing means 45. As the film 61, for example, a circular film provided with discharge holes as discharge ports (not shown) may be used. At this time, the film 61 is arranged so that the discharge holes and the valve holes 52 do not overlap. The Moreover, the linear edge part of the film 61 which forms the discharge outlet 72 may be formed in the shape of a curve, V shape, and a wave, for example, and may be cut | notched vertically. The film 61 is not limited to a shape having an arc, and the outer edge may not necessarily coincide with the outer edge of the upper surface of the base 51. However, the shape of the film 61 should be determined in consideration of the discharge performance and the seal performance of the discharge valve 71.

Next, a method for manufacturing the cap 40 of the dispensing container 1 according to this embodiment will be described. The manufacturing method of the cap 40 includes a mounting step S1 for mounting the base 51 on the receiving base 100, an adhesion step S2 for bringing the film 61 on the upper surface of the base 51 and closely contacting it, and press-fitting the base 51 into the cap body 41. It consists of press-fitting process S3.

In the mounting step S1, the base 51 is mounted on the receiving base 100. For the cradle 100, for example, a cylindrical body into which the seal cylinder 53 of the base 51 is fitted can be used. When such a cradle 100 is used, the base 51 can be stably fixed. Further, in order to position the base 51 in the circumferential direction, the base 100 and / or the base 51 are provided with unevenness, for example, or the position of the valve hole 52 of the base 51 is shifted from the center. Positioning means such as providing a pin (not shown) to be inserted into the valve hole 52 in the base 100 may be added.

In the adhesion step S2, the film 61 is overlaid on the upper surface of the base 51 with the outer edge of the arc portion aligned. At this time, by using an adhesion means (not shown) for bringing the film 61 into close contact with the upper surface of the base 51, it is possible to prevent occurrence of positional deviation, wrinkling and tearing of the film 61 which causes a sealing failure of the discharge valve 71.

As an adhesion method using the adhesion means, for example, the film 61 is configured such that the inside of the receiving base 100 is set to a negative pressure by using suction means such as a vacuum pump (not shown) and is sucked from the valve hole 52 of the base 51. The film 61 is made to adhere to the upper surface of the base 51 by attaching a liquid such as water to the upper surface of the base 51 and / or the film 61 and superimposing the film 61 on the upper surface of the base 51. A method of bringing the film 61 into close contact with the upper surface of the base 51 and / or a method of charging the static electricity to the upper surface of the base 51 and / or the film 61 by a charging means such as corona discharge and the film 61 being brought into close contact with the upper surface of the base 51 can be used.

In the press-fitting step S3, the cap body 41 is pushed over the base 51 so that the upper surface of the base 51 and the film 61 is in close contact with the sealing means 45 of the cap body 41.

When the cap body 41 is press-fitted, the arc peripheral edge of the film 61 is fixed to the sealing means 45, and a discharge port 72 serving as the outlet of the discharge valve 71 is formed at the linear end of the film 61 that does not contact the sealing means 45. Is done. Further, in the film 61, a portion located inside the sealing means 45 becomes a valve body of the discharge valve 71, and is in close contact with the upper surface of the base 51 in a detachable manner.

In the press-fitting step S3, it is sufficient that the cap main body 41 is press-fitted until at least the film 61 is fixed in contact with the sealing means 45 of the cap main body 41. The sealing means 45, the base 51, and the upper surface of the film 61 are not necessarily required. And the upper surface of the base 51 at the contact portion with the sealing means 45 and the film 61 need not be in close contact with each other. In this case, when the cap 40 is attached to the spout 12, the base 51 is pushed by the mouth portion 13 of the spout 12, so that the sealing means 45, the base 51 and the upper surface of the film 61 are in close contact with each other. The sealing means 45 is sealed with the base 51 and the upper surface of the film 61, and the upper surface of the base 51 and the film 61 are sealed at the contact portion with the sealing means 45.

When the contents are liquid, the sealing performance between the sealing means 45, the base 51 and the upper surface of the film 61, and the sealing performance between the base 51 and the film 61 at the contact portion with the sealing means 45 should be at least liquid-tight. For example, the leakage of the contents to the space 20 between the inner container 11 and the outer container 21 can be prevented. The intrusion of outside air into the inner container 11 is caused by the action of negative pressure in the inner container 11 and the base 51 due to the capillary suction force of the contents interposed in the gap between the upper surface of the base 51 and the film 61 as described later. This is prevented by the adhesion of the film 61 to the upper surface. In addition, when the contents are gas, airtightness is required.

The above manufacturing method is a preferable example, and the manufacturing method of the cap 40 is not limited to a specific method. However, in order for the discharge valve 71 of the cap 40 to normally exhibit a check function, at least when the cap 40 is attached to the spout 12, at least when the film 61 is not wrinkled or broken, the sealing means 45 and the base 51 and the upper surface of the film 61 are in close contact with each other, the sealing means 45 and the base 51 and the upper surface of the film 61 are sealed, and the upper surface of the base 51 and the film 61 are sealed at the contact portion with the sealing means 45. A manufacturing method in which the valve body portion of the film 61 is peelably adhered to the upper surface of the base 51 should be used.

In the present invention, the state in which the discharge valve 71 is formed means that the sealing means 45, the base 51, and the film 61 are in the stage where the base 51 and the film 61 are attached to the cap body 41 as described above. The upper surface of the base 51 and the film 61 at the contact portion with the upper surface and the sealing means 45 are sealed, and the cap 40 is not limited to the state in which the discharge valve 71 normally performs the check function. These seals are performed when attached to the spout 12 (the mouth of the container main body), and the discharge valve 71 includes a state in which the check function is normally exhibited.

In the dispensing container 1, the inner container 11 is filled with the contents, the inner container 11 is accommodated in the outer container 21, the intake valve body film 38 is placed on the upper flange 15 of the spout 12, and the ring cap 31 is placed in the outer container. The cap 40 is then screwed into the spout 12 and then manufactured. In addition, the manufacturing method of the extraction container 1 is not limited to this, For example, what is necessary is just to perform filling of the content at the optimal timing suitably.

Note that the cap 40 and the spout 12 may be provided with a locking claw (not shown) that locks the cap 40 and the spout 12 so that they cannot be easily removed once screwed together. By preventing the cap 40 and the spout 12 from being easily removed, it is possible to prevent the contents from being oxidized due to the removal during use or the entry of foreign substances by a third party.

In addition, after the contents are completely poured out, the outer container 21, the ring cap 31, the intake valve body film 38, and the cap 40 are repeated by refilling only the inner container 11 with a new one filled with the contents. Can be used. In this case, a thin-film sealing material (not shown) is adhered to the mouth portion 13 of the spout 12 to seal the mouth portion 13, and the sealing material is broken and opened by the sealing cylinder 53 of the cap 40. By doing so, it is possible to prevent the contents from being oxidized during refilling.

As a method for preventing the oxidation of the contents at the time of refilling without using a sealing material or the like, the outer container 21 in which the inner container 11, the ring cap 31, the intake valve body film 38, and the cap 40 are assembled is used. A method of refilling can also be used. In addition, the selection of what is repeatedly used and what is to be refilled may be appropriately determined according to the application.

Next, the method of use will be illustrated by taking as an example the case where the contents are soy sauce and the dispensing container 1 is used as a soy sauce bottle for antioxidant. After the cap 40 is attached to the spout 12, the lid 49 is opened, and the outer container 21 is pressed and contracted with the dispensing container 1 facing upward. When the outer container 21 is contracted, the space 20 between the outer container 21 and the inner container 11 is pressurized, the intake valve 75 is closed, and the inner container 11 is pressurized and contracted. When the inner container 11 contracts, the film 61 rises and the discharge valve 71 opens, and the air or gas remaining in the inner container 11 is discharged. Thereby, the inside of the inner container 11 is filled with soy sauce, and air is prevented from entering by the discharge valve 71, so that the soy sauce is not oxidized.

When pouring out the soy sauce, when the pouring container 1 is tilted downward and the outer container 21 is pressed and contracted, the inner container 11 contracts and the soy sauce flows into the discharge valve 71 from the valve hole 52, and the film 61 rises. Then, the discharge valve 71 is opened, soy sauce is discharged from the discharge port 72 and poured from the spout 42.

When the contraction of the outer container 21 is stopped and the dispensing container 1 is returned upward, due to the negative pressure in the inner container 11 and the capillary suction force of soy sauce interposed in the gap between the upper surface of the base 51 and the film 61 The film 61 quickly comes into close contact with the upper surface of the base 51 and the discharge valve 71 is closed. For this reason, air does not enter the inner container 11 after the valve is closed. Further, due to the shape recoverability of the outer container 21, the space 20 between the outer container 21 and the inner container 11 becomes negative pressure, the intake valve 75 is opened, and the space between the outer container 21 and the inner container 11 is opened. Outside air flows into 20 and the outer container 21 returns to its original shape.

As described above, the cap 40 of the dispensing container 1 of the present embodiment is configured to be easy to manufacture because the base 51 is attached to the cap body 41 with the film 61 overlapped on the upper surface of the base 51. For this reason, not only the container body used in the present embodiment but also, for example, when used for a commercially available container body, the shape of the cylindrical portion of the cap body 41 is changed in accordance with the shape of the mouth of the container body. By doing so, it is possible to apply a commercially available container body with no modification, so that it is excellent in convenience.

In the pouring container 1 of the present embodiment, screwing is used for connecting the cap 40 and the spout 12, but the present invention is not limited to this, and fitting, press-fitting, adhesion, etc. using a snap fit or the like. It is also possible to connect the cap 40 and the spout 12 by this method. The same applies to the connection between the outer container 21 and the ring cap 31.

Further, the method of attaching the cap body 41 and the base 51 is not limited to press-fitting. For example, as in a cap 101 of the fourth embodiment and a cap 111 of the fifth embodiment, which will be described later, the locking means 103 is used. A method of locking using a screw, a method of screwing, bonding, or the like can be used.

Further, since the mouth portion 13 of the spout 12 is sealed by the seal cylinder 53 of the cap 40, it is not always necessary to contact the lower surface of the base 51 as shown in FIG.

FIG. 6 is a perspective view showing the configuration of the dispensing container 2 of the second embodiment of the present invention. FIG. 7 is a perspective view of the cap body 82 of FIG. FIG. 8 is a perspective view of the base 83 of FIG. FIG. 9 is a cross-sectional view of a main part of the dispensing container 2 of FIG. The same components as those of the dispensing container 1 of the first embodiment shown in FIG. 1 and FIG. In FIG. 9, the film body 18 of the inner container 11 is omitted.

The dispensing container 2 of the present embodiment has the same basic configuration as the dispensing container 1 of the first embodiment, but the film 61 serves as both the valve body of the discharge valve 71 and the valve body of the intake valve 75. Accordingly, the extraction container 2 is different from that of the extraction container 1 of the first embodiment in the structure of the ring cap 81, the cap body 82, and the base 83, and does not have the intake valve body film 38. Moreover, in the extraction container 2 of this embodiment, the ring cap 81 and the cap main body 82 are connected.

The ring cap 81 is formed with a connecting portion 91 that is connected to the lower end portion of the cap body 82 by protruding the outer edge portion of the insertion port 32, and a fitting protrusion of the cap body 82, which will be described later, is formed on the inner peripheral surface of the connecting portion 91. A fitting groove 92 for fitting the portion 94 is formed. The ring cap 81 does not have an intake passage. However, it is also possible to form an extraction container (not shown) provided with an intake passage (not shown) in the ring cap 81 and provided with an intake valve element film (not shown) for opening and closing the intake passage. In the present embodiment, the ring cap 81 corresponds to an outer container cap.

The cap body 82 includes an intake hole 93 that is formed in a part of the top portion and serves as an inlet of the intake valve 75, and a fitting convex portion that fits into the fitting groove 92 of the ring cap 81 at the lower end portion of the outer peripheral surface of the cylindrical portion. 94, and a positioning groove 95 serving as a positioning means in the circumferential direction of the base 83 with a certain width in the vertical direction is provided in a part of the inner peripheral surface of the cylindrical portion. The positioning groove 95 also serves as an intake path for introducing outside air from the intake hole 93 to the space 20 between the outer container 21 and the inner container 11. Furthermore, the position of the positioning groove 95 is preferably determined so that the spout 42 of the cap body 82 and the valve hole 52 of the base 83 are arranged on the opposite sides with respect to the center.

The air intake hole 93 is disposed outside the sealing means 45 in a plan view so as to introduce outside air into the space 20 between the outer container 21 and the inner container 11. Note that the shape and number of the intake holes 93 are not limited to a specific one, and may be provided at a plurality of locations, for example, a cap 181 of a twelfth embodiment described later.

The base 83 has a step 96 formed on the upper surface, and a positioning piece 97 that fits into the positioning groove 95 of the cap body 82 is formed on the outer peripheral surface. The shape of the positioning piece 97 is not limited to a specific shape, but the positioning groove 95 of the cap body 82 is not closed so that outside air can be introduced into the space 20 between the outer container 21 and the inner container 11. It needs to be in shape.

In the cap 80 of the dispensing container 2 of the present embodiment, when the film 61 is stacked on the upper surface of the base 83 that is one step higher, the peripheral edge of the film 61 floats up and down freely without contacting the base 83. It becomes. In the dispensing container 2 of the present embodiment, the portion of the film 61 that contacts the upper surface of the base 83 that is one step higher becomes the discharge valve body 62 that serves as the valve body of the discharge valve 71, and the peripheral edge that does not contact the base 83 A part of the portion serves as an intake valve body 63 serving as a valve body of the intake valve 75. The peripheral portion of the film 61 that does not contact the base 83 only needs to have at least the intake valve body 63 that can open and close the intake hole 93 of the cap body 82, and other portions may be cut off, for example.

The shape and arrangement of the film 61 are not limited to specific ones as in the case of the dispensing container 1 of the first embodiment, but the base covers the valve hole 52 and allows the valve hole 52 to be opened and closed freely. 83 is sandwiched between the upper surface which is one step higher and the sealing means 45 of the cap main body 82, and the discharge port 72 is in a shape and arrangement located on the inner side (near the center) than the sealing means 45, in addition to the intake hole It is necessary to make 93 the shape and arrangement | positioning which can be opened and closed.

When the base 83 on which the film 61 is stacked is press-fitted into the cap main body 82, the film 61 is pressed by the sealing means 45 of the cap main body 82, and the discharge valve 71 is formed like the cap 40 of the dispensing container 1 of the first embodiment. At the same time, the intake valve body 63 of the film 61 covers the intake hole 93 of the cap body 82 so as to be freely opened and closed, and the intake valve 75 is formed. In addition, since the manufacturing method of the cap 80 of the extraction container 2 of this embodiment is the same as that of the cap 40 of the extraction container 1 of 1st Embodiment, description is abbreviate | omitted.

When the cap 80 is attached to the mouth portion 13 of the spout 12 of the inner container 11, is connected to the ring cap 81, and the outer container 21 is attached to the ring cap 81, the space between the outer container 21 and the inner container 11 from the intake hole 93. A flow path of outside air to the unit 20 is formed.

As described above, in the dispensing container 2 of the present embodiment, since the film 61 also serves as the valve body of the discharge valve 71 and the intake valve 75, when the intake valve body film 38 is used, or as the intake valve 75, the other reverse Compared with the case where a stop valve is used, material cost and manufacturing cost can be reduced. In addition, since both the discharge valve 71 and the intake valve 75 are provided in the cap 80, for example, when using an existing container that is commercially available as a container body, an intake hole (intake passage) or an intake valve is newly provided in the container body. There is no need to provide it.

In addition, the connection method of the ring cap 81 and the cap main body 82 is not limited to a specific method, For example, you may employ | adopt the method using a screw | thread, a snap fit, etc., adhesion | attachment, etc.

In addition, the connecting method between the outer container 21 and the ring cap 81, the connecting method between the spout 12 and the cap 80, and the attaching method between the cap body 82 and the base 83 are also specified as in the dispensing container 1 of the first embodiment. It is not limited to the method.

The positioning method of the cap body 82 and the base 83 is not limited to a specific method, and for example, a method used in the cap 131 of the seventh embodiment and the cap 141 of the eighth embodiment described later may be used.

Also in the dispensing container 2 of the present embodiment, as with the dispensing container 1 of the first embodiment, after the content has been completely poured out, only the inner container 11 or the inner container 11 and another member are connected in advance. It is possible to refill the outer container 21 for use.

FIG. 10 is a diagram showing a configuration of the dispensing container 3 according to the third embodiment of the present invention. 10A is a cross-sectional view of the main part of the dispensing container 3 according to the third embodiment of the present invention, and FIG. 10B is a perspective view of the base 86 in FIG. 10A. In FIG. 10A, the film body 18 of the inner container 11 is omitted. The same components as those of the dispensing container 2 of the second embodiment shown in FIG. 6 and FIG.

The pouring container 3 of the present embodiment has the same basic configuration as the pouring container 2 of the second embodiment, but the shape of the base 86 makes it easier to generate wrinkles of the film 61 when the cap 85 is manufactured. The shape can be reliably prevented.

The base 86 includes three small-diameter valve holes 87, and includes a groove 98 instead of the step 96 of the base 83 of the dispensing container 2 of the second embodiment. The entire upper surface of the base 86 is flat except for the groove 98.

The groove 98 is formed by forming a part of the peripheral edge of the upper surface of the base 86 in a concave shape, and is covered with the film 61 to serve as a valve opening allowance for the intake valve 75. The base 86 is attached to the cap body 82 such that the film 61 is overlaid on the upper surface and the groove 98 is disposed directly below the intake hole 93 of the cap body 82. At this time, a part of the film 61 covering the groove 98 becomes the intake valve body portion 63 and opens and closes the intake hole 93. A notch 136 may be provided instead of the groove 98 as in the bases 133 and 143 of the caps 131 and 141 of the seventh and eighth embodiments described later.

In the dispensing container 3 of the present embodiment, the upper surface of the base 86 and the arc portion of the film 61 have substantially the same diameter, so the film 61 is similar to the base 83 of the dispensing container 2 of the second embodiment. The film 61 is more likely to be in close contact with the upper surface of the base 86 than when the peripheral edge thereof is not in contact with the base 83, and the film 61 is less likely to wrinkle. However, this does not mean that wrinkles are likely to occur in the film 61 in the dispensing container 2 of the second embodiment.

Further, when the suction means is used in the adhesion step S2 described above, since three valve holes 87 are provided in the base 86, the suction points of the film 61 are dispersed and the film 61 is unlikely to be wrinkled. Note that the number of valve holes 87 is not limited to three, and the number of valve holes 87 can more reliably prevent the formation of wrinkles on the film 61 as compared with the case of one.

In the pouring container 3 of the present embodiment, the film 61 is entirely the base 86 except for the intake valve body 63 if the diameter of the arc portion is equal to or smaller than the diameter of the upper surface of the base 86. Since the film 61 is in close contact with the upper surface of the base 86, the film 61 is easily adhered to the upper surface of the base 86, and the film 61 is less likely to wrinkle. However, the film 61 covers the three valve holes 87 and is sandwiched between the upper surface of the base 86 and the sealing means 45 of the cap body 82 so that the valve holes 87 can be opened and closed, and the discharge port 72 is located inside the sealing means 45. In addition to the shape and arrangement located near the center, it is necessary to further form a shape and arrangement that covers a part of the groove 98 so that the intake hole 93 can be opened and closed.

Also in caps 161, 171, 181 and 200 of the tenth to thirteenth embodiments to be described later, grooves 98 or notches 136 are provided in place of the steps 96 as in the base 86 of the dispensing container 3 of the present embodiment. Thereby, the production | generation of the wrinkle of the film 61 can be prevented more reliably. Similarly, a plurality of valve holes 52 in other embodiments can be provided as appropriate.

FIG. 11 is a cross-sectional view of the cap 101 according to the fourth embodiment of the present invention. The same components as those of the cap 40 of the dispensing container 1 of the first embodiment shown in FIG. 1 and FIG. The cap 101 of this embodiment has the same basic configuration as the cap 40 of the dispensing container 1 of the first embodiment, but includes a locking means 103 that locks the base 51 to the cap body 102.

On the inner peripheral surface of the cylinder portion of the cap body 102, a claw-like locking means 103 is formed over the entire circumference at a position lowered from the sealing means 45 by the thickness of the base 51. When the base 51 is attached to the cap main body 102, the locking means 103 is formed so as to be gradually inclined toward the upper part so that the base 51 can be guided. Close contact with the lower surface of the base 51. The locking means 103 is not limited to being formed continuously over the entire circumference, and may be formed partially.

When the base 51 is attached to the cap body 102, the base 51 is pushed in until the outer peripheral surface of the base 51 gets over the locking means 103, and the lower surface of the base 51 is closely locked to the upper end surface 104 of the locking means 103. . At this time, it is preferable to determine the formation position of the locking means 103 in consideration of the thickness of the base 51 so that the upper surfaces of the base 51 and the film 61 are tightly sealed to the sealing means 45. If the base 51 is pushed in when the cap 101 is attached to the mouth of the container main body and can be sealed, the film 61 may be fixed.

Also, when the outer peripheral surface of the base 51 gets over the locking means 103, the locking means 103 and the film 61 come into contact with each other, so that the film 61 is not uniformly tensioned and wrinkles or tears are not generated. 103 and the shape of the periphery of the upper surface of the base 51 need to be determined. For example, the base 51 is chamfered on the edge of the upper surface of the base 51 by the thickness of the upper end surface 104 of the locking means 103 and the film 61 having the same diameter as that of the upper surface of the base 51 after chamfering is overlapped. By attaching 51 to the cap body 102, contact between the locking means 103 and the film 61 can be avoided.

FIG. 12 is a cross-sectional view of the cap 111 according to the fifth embodiment of the present invention. The same components as those of the cap 40 of the dispensing container 1 of the first embodiment shown in FIG. 1 and FIG. The cap 111 of the present embodiment has the same basic configuration as the cap 40 of the dispensing container 1 of the first embodiment, but includes a female screw 114 and a male screw 115 that are screwed into the cap body 112 and the base 113. Prepare.

The female screw 114 provided on the inner peripheral surface of the cylindrical portion of the cap main body 112 is arranged so that the upper surface of the base 113 and the film 61 are tightly adhered to and sealed with the sealing means 45 when the base 113 is screwed. Is done.

In order to prevent the base 113 from coming off after the base 113 is screwed, a claw (not shown) that locks the base 113 and the cap main body 112 may be provided, and the base 113 is screwed. Later, the base 113 and the cap body 112 may be partially bonded.

FIG. 13 is a cross-sectional view of the cap 121 according to the sixth embodiment of the present invention. The same components as those of the cap 40 of the dispensing container 1 of the first embodiment shown in FIG. 1 and FIG. The cap 121 of this embodiment includes a ring member 124 that is disposed between the ceiling surface 43 of the cap body 122, the base 123, and the film 61.

The cap 121 of the present embodiment includes a seal cylinder 125 that seals the mouth of the container body in the cap body 122, and the base 123 is attached to the seal cylinder 125 with a ring member 124 press-fitted into the seal cylinder 125 interposed therebetween. It is configured to press fit into the inner peripheral surface.

The ring member 124 has an outer diameter that is substantially the same as the inner diameter of the seal cylinder 125 of the cap body 122, and includes convex sealing means 126, 127 formed on the upper surface and the lower surface over the entire circumference. It is press-fitted into the seal cylinder 125 of the cap body 122 so that 126 is in close contact with the ceiling surface 43 of the cap body 122. Since the material of the ring member 124 is the same as that of the base 123 and the like, description thereof is omitted.

If the upper and lower surfaces of the ring member 124 can be in close contact with the ceiling surface 43, the base 51 and the upper surface of the film 61 of the cap body 122, the sealing means 126 and 127 need not be provided. . As the ring member 124, a gasket or the like can be used.

The base 123 is a disc body and does not include a ring-shaped seal cylinder.

As described above, the dispensing

containers

1, 2, 3, 4 and the

caps

40, 80, 85, 101, 111, 121, 131, 141, 151, 161, 171, 181 and 200 of the first to thirteenth embodiments are used. The cap of the present invention, the dispensing container including the cap, and the method for manufacturing the cap have been described. However, the cap of the present invention, the dispensing container including the cap, and the method for manufacturing the cap are limited to the above embodiment. However, the present invention can be modified and used without changing the gist.

As the base, a disk body having a seal cylinder on the lower surface is mainly used, but the present invention is not limited to this, and the upper surface and the lower surface of the base may be provided with unevenness. Further, the upper surface of the base need not be flat, and may be provided with irregularities or the like as long as it can be in airtight contact with the sealing means 45 of the cap body. Further, the base, the film, the cap body, and the ring member are not limited to a circle in plan view, and may be a polygon such as a rectangle.

When the base is attached to the cap body, a structure in which tension is uniformly applied to the film can improve the adhesion between the film and the upper surface of the base and improve the sealing performance of the discharge valve 71. For example, when the upper surface of the base is formed in a dome shape, it is easy to apply a uniform tension to the film, and the tension also works in the direction in which the film is brought into close contact with the base. Therefore, the sealing performance of the discharge valve 71 is improved, which is preferable. . For such a structure, for example, refer to the extraction cap shown in FIGS. 4, 6, and 7 described in Japanese Patent Application No. 2013-100316 (Japan Patent Office) filed by the present applicant. it can.

For example, a capillary suction force is applied to the valve seat of the base as in the check valve unit shown in FIGS. 31 and 32 described in International Application No. PCT / JP2013 / 83871 filed by the present applicant. For this purpose, a vein-like groove or a groove provided over the entire width may be formed. By providing such a groove, the sealing performance of the discharge valve 71 can be improved. The depth of the groove is appropriately determined to be a depth at which the liquid always stays and a depth at which the liquid can be exchanged smoothly. If the groove is too deep, the liquid cannot be exchanged smoothly and should not be deeper than necessary.

Also, the shape of the groove provided in the valve seat of the base is not limited to a specific shape, and for example, a groove such as a round mark or an X mark may be provided. Further, the same effect can be obtained by roughening the surface instead of the groove or providing small irregularities on the surface.

The mounting method of the base to the cap body is not limited to press-fitting, locking, and screwing. For example, the upper surface of the base and the pressing surface of the cap body are used by vibration welding or ultrasonic welding. It may be glued. As long as the film does not cause wrinkles or tears and the film is in close contact with the upper surface of the base so that the valve hole can be opened and closed, an optimum method may be adopted as appropriate in consideration of manufacturing costs and the like. .

In the present invention, the state in which the discharge valve (and the intake valve) is formed means that when the base and the film are attached to the cap body, the upper surface of the base and the film and the cap body (seal means). The contact portion is sealed, and the upper surface of the base and the film at the contact portion are sealed, and the discharge valve (and the intake valve) is not limited to a state in which the check function is normally exhibited. These seals are made when attached to the mouth portion, and include a state in which the discharge valve (and intake valve) normally exhibits the check function.

The air-tightness of the intake valve 75 only needs to be maintained to such an extent that the contents can be discharged. For example, the outer container 21 is unexpectedly pressurized when the pouring container 2 falls, and the contents leak out. In order to prevent the air in the space portion 20 from expanding due to thermal expansion and pressurizing the inner container 11 to leak the contents, the intake valve 75 and the female screw 37 of the ring cap and the outer container 21 are prevented. The air may be intentionally somewhat leaked from the gap with the male screw 23.

The intake valve 75 is not limited to a check valve using a film. For example, a known check valve (not shown) using a ball, a movable plate member, or the like can be attached. is there. Further, instead of the intake valve 75, a leak means (not shown) such as a hole or a gap for circulating air may be provided.

The leakage means is provided so that the amount of air leakage from the space 20 when the outer container 21 is contracted is limited to the extent that the contents can be discharged from the inner container 11. When the contents are poured out, the leak means may be blocked with a finger or the like to prevent air leakage from the space portion 20. When the shape of the outer container 21 is restored, outside air is introduced from the leak means into the space 20.

In the dispensing container 1 of the first embodiment, the intake passage 33 is provided in the ring cap 31, but is not limited to this, and the intake passage 33 and the intake valve 75 are part of the outer container 21. It may be provided. At this time, instead of the intake passage 33 and the intake valve 75, the above-described leakage means may be provided in the outer container 21.

The container body is not limited to the double container used in the dispensing

containers

1, 2, 3, and 4 of the first to third and thirteenth embodiments. For example, the inner container is peeled from the outer container. A delamination bottle (lamination peelable container) or the like formed by being laminated may be used.

The container body is not limited to a double container. For example, a plastic container, a paper liquid container, a bag container that is commercially available, etc., and a container body that can shrink as the contents are discharged are appropriately selected. Can be used. When a double container is not used for the container body, the intake valve 75 is not necessary, and a cap in which only the discharge valve 71 is formed can be suitably used.

As described above, the material of the cap and the dispensing container of the present invention can be appropriately selected and used according to the use and contents to be contained. Even when other parts are added to the cap and dispensing container of the present invention, the material of the part is appropriately selected and used according to the intended use and contents to be contained. do it. For example, in order to prevent the liquid contained in the dispensing container from being oxidized, all members (including parts) in contact with the liquid or main members may be made of a material having excellent oxygen barrier properties. Needless to say, it is preferable that the material to be used is inexpensive and easily available as long as it satisfies a predetermined performance.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily consider various changes and modifications within the obvious range by looking at the present specification. Therefore, such changes and modifications are interpreted as being within the scope of the invention defined by the claims.
