JP6380998B2 - Valve member and pouring container provided with the valve member - Google Patents

Description

  The present invention relates to a valve member capable of preventing the intrusion of outside air into a container body and a dispensing container including the valve member.

  A non-return valve (discharge valve) is installed on the container body as a container that can dispense liquid while preventing the outside air from entering the container body containing liquid such as soy sauce. Many things have been developed that are attached to the mouth.

  In such a pouring container, the container body contracts as the contents are poured out, so that there is a problem that it becomes impossible to stand by itself during use and the appearance is deteriorated. In order to solve this problem, a double-structured container main body composed of an inner container for storing contents and an outer container having a shape restoring property and capable of supporting itself is used.

  When using a container body with a double structure, when the contents are poured out, the outer container is pressurized and deformed, and the inner container is pressurized via the fluid in the space between the outer container and the inner container. To be poured out. At this time, it is necessary to take the fluid into the space between the outer container and the inner container and to prevent the fluid from flowing out from the space between the outer container and the inner container when the contents are poured out. A stop valve (intake valve) is used.

  In order to reduce the number of check valves used in a dispensing container having a double-structured container body, a technique has been developed that adds a function as an intake valve to a discharge valve attached to the mouth of the container body (for example, (See Patent Documents 1 and 2).

Even in such a state, the outer container 21 can stand by itself. It should be noted that the outer container 21 is easy to use and is preferably self-supporting. However, the outer container 21 is not limited to this, and a container that is not self-supporting can be used depending on the application.

  The container body 10 is a delami bottle (laminated peelable container) formed by laminating the inner container 11 with respect to the outer container 21, but is not limited thereto. A pouch-type inner container 16 and the like can be accommodated in the outer container 21 as in the dispensing container 2 of the embodiment.

  In addition, as the inner container 11, a container body (not shown) provided with a folding line that contracts while the contents described in PCT / JP2013 / 065781 filed by the applicant is applied, or the present application. A container body (not shown) having a bellows in which the inside of the container body is forcibly depressurized by the shape restoration property described in Japanese Patent Application No. 2012-101940 filed by a person can also be suitably used.

  The inner container 11 is formed by being laminated from the inner wall surface of the outer container 21 to the distal end surface of the mouth portion 22, and peels off from the outer container 21 and contracts as the contents are poured out. The material of the inner container 11 is not limited to a specific material. Depending on the contents to be stored, thermal stability, prevention of deterioration by ultraviolet rays, antistatic, antioxidant, water vapor barrier, other gas barrier properties (gas barrier properties), aroma storage properties, light shielding properties, etc. are required. In such a case, the inner container 11 may be appropriately formed using a material suitable for the required specifications.

The contents include a relatively low viscosity liquid such as soy sauce, a viscous fluid such as mayonnaise, a gas such as sampling gas, a granular material such as wheat flour, a slurry solution, and a suspension in which solids are suspended in the liquid. Examples include turbid solutions. Typical soy sauce has a viscosity of about 5 to 6 mPa · s at a temperature of 20 ° C., and mayonnaise has a viscosity of about 2 to 100 Pa · s.

  It is preferable that the outer container 21 is easily contractible and deformable, has shape recoverability, and can be self-supporting. The material of the outer container 21 is not limited to a specific material like the inner container 11. Depending on the contents to be stored, thermal stability, prevention of deterioration by ultraviolet rays, antistatic, antioxidant, water vapor barrier, other gas barrier properties (gas barrier properties), aroma storage properties, light shielding properties, etc. are required. In such a case, a material suitable for the required specifications may be used as appropriate. This point can be considered similarly to the inner container 11, and the above-described materials can be used.

  The outer container 21 is formed by screwing and engaging an outer air introduction hole 23 that is formed in the mouth portion 22 and serves as an inlet for the outside air into a space between the inner container 11 and a cap 61 that is provided on the outer peripheral surface of the mouth portion 22. A male screw 24 and a locking claw 25 are provided.

  The outside air introduction hole 23 is provided at a position covered by the cylindrical portion 69 of the cap 61 so that the intake passage 9 is formed when the cap 61 is attached to the outer container 21. The shape of the outside air introduction hole 23 is not limited to a specific shape, and can be, for example, a circular hole, a rectangular hole, a star hole, or the like.

  The locking claw 25 is connected to the locking claw 71 of the cap 61 when the cap 61 is attached to the outer container 21. The locking claw 25 of the outer container 21 and the locking claw 71 of the cap 61 are inclined in directions opposite to each other. When the cap 61 is screwed into the mouth portion 22 of the outer container 21, the locking claw 25 gets over each inclined surface. Are engaged in this way. As a result, once the cap 61 is attached to the outer container 21, it cannot be easily removed, and the opening of the dispensing container 1 during use can be prevented and the entry of outside air into the inner container 11 can be prevented. .

  The method for attaching the cap 61 to the outer container 21 and the method for preventing the removal of the cap 61 are not limited to a specific method, and may be, for example, fitting using a snap fit, press fitting, adhesion, or the like.

  The valve member 31 includes a base 41 in which a cylindrical seal cylinder 45 is formed on the lower surface of a flat plate, and a film 51 that is bonded to the upper surface of the base 41 and has a discharge valve 38 on the upper surface of the base 41. In addition, the valve body of the intake valve 39 is provided, and the seal cylinder 45 of the base 41 is fitted into the mouth portion 12 of the inner container 11 and attached to the inner container 11.

  The base 41 is positioned so as to position the cap 61 in the circumferential direction with respect to the valve hole 42 serving as the inlet of the discharge valve 38, the notch 43 provided to allow the intake valve body 53 of the film 51 to move up and down. A piece 44, a seal cylinder 45, and a convex portion 46 that is in close contact with the distal end surface of the mouth portion 12 of the inner container 11 are provided.

  The material of the base 41 is not limited to a specific material, and examples of the material include synthetic resin materials such as polyethylene, metal, glass, carbon material, sintered material, 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 base 41, as in the case of the inner container 11, the base 41 is made of plastic, composite material, laminated material, or other material having excellent oxygen barrier properties and air barrier properties. May be formed.

  The valve hole 42 and the notch 43 are provided on the opposite side of the positioning piece 44 across the center of the base 41. In this arrangement, when the valve member 31 and the cap 61 are positioned by the positioning piece 44 and a positioning groove 67 of the cap 61, which will be described later, the circumferential positions of the notch 43 and the intake port 64 of the cap 61 are matched. In addition, the valve hole 42 and the spout 63 of the cap 61 are determined so as to be located on opposite sides of the center of the base 41.

  By matching the circumferential position of the notch 43 and the intake port 64 of the cap 61, the circumferential position of the intake valve body 53 of the film 51 and the intake port 64 of the cap 61 is matched, and the intake valve 39 is Can be formed.

  Further, since the valve hole 42 and the spout 63 of the cap 61 are located on opposite sides of the center of the base 41, the air or gas in the inner container 11 mixed at the time of filling the contents is injected. When the contents are poured out by tilting the outlet container 1, it moves toward the valve hole 42, which is preferable because it is easily discharged to the outside. However, the positional relationship between the valve hole 42 and the spout 63 of the cap 61 is not limited to this.

  In short, the valve holes 42, the notches 43, and the positioning pieces 44 are arranged so that at least the circumferential positions of the notches 43 and the inlets 64 of the cap 61 coincide with each other. You can decide according to.

  The valve hole 42 is a circular hole drilled at three locations in the flat plate portion, and is drilled inside the seal cylinder 45 so that the contents in the inner container 11 can flow in. However, the number and shape of the valve holes 42 are not limited to this.

  The cutout 43 is formed on the flat plate portion so that the intake valve body 53 of the film 51 covering the cutout 43 can be moved up and down by receiving the pressure of fluid (air) from the vertical direction so that the intake valve 39 can be opened and closed. A part of the peripheral edge is provided in an open shape.

  The positioning piece 44 is formed such that a part of the upper surface of the peripheral portion of the flat plate portion is raised on a partial arc, and is fitted into a positioning groove 67 provided in a pressing surface 65 of the cap 61 described later, and the valve member 31. And the cap 61 are positioned in the circumferential direction.

  The shape of the positioning piece 44 and the positioning method of the valve member and the cap in the pouring container of the present invention are not limited to a specific shape or method. For example, the pouring container of the third embodiment to be described later The positioning piece 82 and the positioning pin 83 used in 3 may be used.

  The seal cylinder 45 is formed in a cylindrical shape on the lower surface of the base 41, is fitted into the mouth portion 12 of the inner container 11, and seals in close contact with the inner peripheral surface of the mouth portion 12 of the inner container 11. The seal cylinder 45 has a tapered tip so that it can be easily fitted into the mouth 12 of the inner container 11.

  The convex portion 46 is a projection having a semicircular cross section provided in a ring shape on the lower surface of the base 41, and seals in close contact with the distal end surface of the mouth portion 12 of the inner container 11.

  The method for sealing the mouth portion 12 of the inner container 11 is not limited to the method using the seal tube 45 and the convex portion 46, and for example, only one of them may be used. You may make it seal on the lower surface of the base 41, without using the convex part 46. FIG. The shapes of the seal cylinder 45 and the convex portion 46 are not limited to specific shapes. Further, sealing may be performed through a gasket (packing) or the like, or the lower surface peripheral portion of the base 41 and the distal end surface of the mouth portion 12 of the inner container 11 may be bonded.

  The film 51 is a thin film, and includes a thin film having flexibility, flexibility, and stretchability. The thickness of the film 51 is not particularly limited, and can be appropriately selected and used according to the application, contents, material, adhesion method, and the like. However, it is preferable that the film 51 is thin from the viewpoint of the sealing performance between the valve member 31 and the convex portion 68 of the cap 61 described later. In this case, it is needless to say that the film 51 functions as a valve body of the discharge valve 38 and the intake valve 39 and should not be damaged when the film 51 is bonded to the base 41. The sealing performance between the valve member 31 and the convex portion 68 of the cap 61 will be described later. If an example of the thickness of the film 51 is shown, when the content is a liquid with a relatively low viscosity such as soy sauce (general soy sauce), it is about 10 to several hundred μm with a polyethylene film. However, it is not limited to this value.

  The material of the film 51 is 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, or the like. Although illustrated, it is not limited to a specific material, According to a use, the content, the adhesion method to the base 41, etc., it can select suitably and can be used. For example, in order to prevent oxygen from entering the inner container 11 through the film 51, 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 barriers. Plastics, composite materials, laminated materials, etc. that are excellent in properties can be suitably used. However, since the film 51 is in a thin film shape, it is easier for gas to pass through compared to the inner container 11 and the like, and therefore it is necessary to select a material in consideration of this point.

  The film 51 has an arcuate partial circular shape having substantially the same diameter as the base 41, a discharge valve body portion 52 that is detachably adhered to the upper surface of the base 41 and serves as a valve body of the discharge valve 38, and a base An intake valve body portion 53 that covers the notch 43 of the base 41 and serves as a valve body of the intake valve 39 is superimposed on the upper surface of the base 41 and the discharge valve body portion 52 and the intake valve body portion 53 are airtightly separated. So that it is glued. The film 51 of the dispensing container 1 of the present embodiment is bonded to the upper surface of the base 41 in the entire area excluding the discharge valve body 52 and the intake valve body 53. A part of the straight part of the film 51 forms a discharge port 54 that becomes an outlet of the discharge valve 38 without being bonded.

  The discharge valve body 52 is a part of the film 51 that covers the valve hole 42 of the base 41 and is in close contact with the upper surface of the base 41 so as to allow the contents to flow from the valve hole 42 to the discharge port 54. The discharge valve body 52 is a valve body, the upper surface of the base 41 is a valve seat, the valve hole 42 is an inlet, and the discharge valve 38 is an outlet. The shape of the discharge valve body 52 is not limited to a specific shape, and may be provided in a meandering shape, for example.

  The intake valve body portion 53 is a part of the film 51 that covers the notch 43 of the base 41. The intake valve body portion 53 serves as a valve body, and the outlet periphery 66 of the intake port 64 located on the holding surface 65 of the cap 61. Is formed as a valve seat and an intake port 64 as an inlet. The intake valve body 53 has a size that can close at least the outlet of the intake port 64.

  The method for adhering the film 51 is not limited to a specific method, and other methods such as laser welding, which will be described later, thermal welding, and adhesion using an adhesive can be used. However, it is necessary to perform bonding in consideration of the following points.

  When the upper surface of the valve member 31 and a pressing surface 65 (convex portion 68) of the cap 61 described later are brought into close contact with each other as in the dispensing container 1 of the present embodiment, the smoothness of the upper surface of the valve member 31 is very important. . If the upper surface of the valve member 31 is sufficiently smooth, even if the upper surface of the valve member 31 is brought into direct contact with the pressing surface 65 (convex portion 68) of the cap 61, airtightness can be ensured. If the smoothness of the upper surface is insufficient, a gasket (packing) or the like needs to be interposed.

  In particular, in the valve member 31 formed by partially overlapping the film 51 on the flat base 41, the upper surface of the valve member 31 includes a portion covered with the film 51 and a portion not covered, In order to directly bring the upper surface of 31 into close contact with the pressing surface 65 (convex portion 68) of the cap 21, there is no step between the portion covered with the film 51 and the portion not covered, or there is a step. The step must be close enough, and the boundary between the portion covered with the film 51 and the portion not covered is important.

  The thickness of the film 51 and the bonding method are largely involved in the step between the portion covered with the film 51 and the portion not covered with the upper surface of the valve member 31. In order to eliminate the step between the portion covered with the film 51 and the portion not covered with the upper surface of the valve member 31, it is preferable that the thickness of the film 51 is thin. In addition, when the film 51 is bonded to the base 41, there is no step between the portion covered by the film 51 and the portion not covered, or a step that can be intimate even if a step occurs. Adhesion method will be adopted. Hereinafter, in the present embodiment, there is no step between the portion covered with the film 51 and the portion not covered with, in addition to the case where the height is the same and there is no physical step, the step that can be closely contacted, That is, it is assumed to include a level difference that can be identified with no level difference.

  As an adhesion method that does not cause a step between the portion covered with the film 51 included in the upper surface of the valve member 31 and the portion not covered, a laser welding method described later can be suitably used. In addition, in the bonding method using an adhesive, there is a method in which the film 51 and the base 41 are partially dissolved. A method of thinly processing a region of the base 41 where the film 51 is overlapped in advance is also conceivable. However, the base 41 needs to be processed, and the base 41 and the film 51 need to be aligned. It takes time and effort.

  For adhesion between the base 41 and the film 51, for example, laser welding can be suitably used. When performing laser welding, a base 41 is set on a mounting table (not shown), and a rectangular film material (not shown) larger than the base 41 is partially covered thereon, and the valve hole 42 is a film. The film material is covered, and the film material is positioned so that one end of the film material is located on the inner side of the end of the positioning piece 44 of the base 41, and the film material is pressed from above with a glass plate (not shown). A laser is irradiated so as to scan a portion to be bonded from above.

  The laser passes through the glass plate and the film material and is absorbed by the base 41. When the laser is absorbed, the upper surface of the base 41 generates heat and melts, and the film material is welded. During welding, the welded portion swells due to heat, but when laser irradiation is stopped, it shrinks with cooling. At this time, since the glass plate is placed on the film material, the welded portion has the same height as the base 41 on which the film material is not stacked or a height at which the same can be seen. For this reason, a level | step difference does not arise between the part coat | covered with the film material contained in the upper surface of the valve member 31, and the part which is not coat | covered.

  After welding, the valve member 31 can be obtained by irradiating a laser along the edge of the base 41 and cutting the film material. When laser welding is used in this way, manufacturing becomes even easier.

  Further, when the base 41 and the film material are welded by laser welding, the film material is welded from a state in which the film material is previously pressed by a glass plate, so that the film 51 is unlikely to cause wrinkles that cause a sealing failure of the discharge valve 38.

  When the base 41 and the film 51 are bonded by laser welding, the base 41 needs to be a material that absorbs laser and the film 51 needs to be a material that transmits laser. As a material of such a base 41, for example, a known material that absorbs the laser 88 can be appropriately selected and used in addition to a synthetic resin material such as polyethylene to which carbon black, titanium oxide, or the like is added. As a material of the film 51, for example, a known material that transmits laser can be appropriately selected and used in addition to a synthetic resin film such as a transparent or translucent polyethylene film.

  The mounting table is not limited to a specific shape and material as long as the base 41 can be mounted and positioned.

  The glass plate prevents the film material from lifting when laser welding is performed, and dissipates heat applied to the film material. If excessive heat is applied to the film material, it may be burned out, but since the heat is radiated by the glass plate, the film material is prevented from being burned out. The glass plate may be cooled with cooling air or cooling water.

  As the glass plate, for example, a hard heat-resistant glass plate or the like can be used. However, the glass plate is not limited to a specific material as long as it can transmit a laser and prevent the film material from being lifted. Moreover, it is not limited to glass.

However, even if other parts are added to the valve member and the dispensing container of the present invention, the material of the part is appropriately selected according to the use and contents to be accommodated. And use 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.

  Moreover, in the said embodiment, although the extraction container provided with a valve member etc. was shown, the valve member is other than the said embodiment, for example, in the middle of a flow path which requires discharge | emission and suction | inhalation of fluid, It may be attached to the end of the passage, the opening of the tank, or the like, and can be attached and used so as to separate the fluid in a space where the fluid stays or moves, such as a container, a void, a cavity, or a pipe. At least one of the fluids separated by the valve member may be the atmosphere.

  As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope 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.
