Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge device, and more particularly to a discharge device comprising a pressurized product in which a container is filled with a stock solution and a pressurizing agent and sealed, and a discharge member detachable from the pressurized product.

Patent Document 1 describes a discharge device in which a discharge member having a valve is attached to a container filled with a stock solution and a pressurizing agent. In this discharge device, the discharge member is detachable from the container. Specifically, the discharge member includes a valve and a cap that covers the valve, and the discharge member is attached to the container by screwing the cap onto a screw provided on the outer circumference of the neck of the container. . Therefore, the discharge member can be reused by removing the discharge member from the container after all the stock solution has been discharged and replacing it with a new container.

Patent Literature 2 describes that a ratchet mechanism is configured between a screw cap and an aerosol container (external container) to restrict rotation of the screw cap in a loosening direction. The screw cap is what secures the valve to the aerosol container. Therefore, by providing the ratchet mechanism as described above, it is possible to prevent the screw cap from being removed from the aerosol container, thereby preventing the valve from being removed from the aerosol container.

WO2015/080252 WO2019/055334

In the discharge device of Patent Document 1, since the discharge member is simply screwed onto the container, it is possible to remove the discharge member before the end of use. If the cap is removed while the stock solution remains, there is a risk that the stock solution will leak out.

In Patent Document 2, the ratchet mechanism prevents the screw cap from being removed from the aerosol container, but since the screw cap cannot be removed from the aerosol container, the valve cannot be reused.

It is a technical object of the present invention to provide a discharge device capable of reusing the valve while suppressing removal of the cap and the valve when the undiluted solution remains.

The discharge device of the present invention comprises a pressurized product 11a in which a container 11 is filled with a stock solution C and a pressurizing agent P and sealed, and a discharge member 12 that pierces the pressurized product 11a and discharges the stock solution C. , the discharge member 12 covers a valve 21, a cap 20A, 20B, 20C that covers the valve 21 and detachably attaches the valve 21 to the pressurized product 11a, and the cap 20A, 20B, 20C. The container 11 includes a container body 16 and a lid body 15 closing an opening of the container body 16, and the lid body 15 is broken through by the discharge member 12. It comprises a closing portion 15d and an engaging cylinder portion 15a1 for forming a seal between the valve 21 downstream of the closing portion 15d, and the inner surfaces of the cover portions 71, 71B and the caps 20A, 20B, 20C and the outer surface thereof form a ratchet mechanism Ra that idles when the cover portions 71 and 71B are rotated in a direction to remove the caps 20A, 20B and 20C.

Further, it is preferable that the valve 21 and the caps 20A, 20B, 20C are integrated. Moreover, it is preferable that the cover portions 71 and 71B include an engaging portion 71a3 that engages the cover portions 71 and 71B with the cap 20A so as to be rotatable about the axis of the cap 20A.

Since the discharge device of the present invention is formed with a ratchet mechanism that idles when the cover part is rotated in the direction to remove the cap, the cap cannot be rotated in the direction to remove the cap even if the cover part is rotated. Therefore, unintentional removal of the cap can be suppressed. On the other hand, if the cover part is removed, the valve can be removed from the pressurized product by removing the cap from the pressurized product, and the valve can be reused.

Further, since the valve and the cap are integrated, removing the cap from the pressurized product automatically removes the valve from the pressurized product. When the cover portion has an engaging portion that engages the cover portion with the cap so as to be rotatable around the axis of the cap, the cover portion is prevented from falling off and the user directly touches the cap. can be suppressed.

A discharge device 10 shown in FIG. 1A comprises a double pressurized container (container) 11, a discharge member 12, and a stock solution (content) C and a pressurizing agent P filled in the double pressurized container 11. As shown in FIG. The pressurized product 11a is obtained by filling the double pressurized container 11 with the concentrate C and the pressurizing agent P. The pressurized product 11a and the discharge member 12 can be used as a set before assembly (see FIG. 1A), or in a half-assembled and unopened state (a state in which a cap 20A described later and a male screw 13e of the outer container 13 are loosely screwed together). ). The pressurized product 11a is sold together with the discharge member 12, and is also sold separately as a replacement. Therefore, the pressurized product 11a is sealed so that the undiluted liquid C and the pressurizing agent P do not leak out until the discharge member 12 is attached (until the discharge member 12 opens the product). The ejection member 12 may also be sold separately.

The double pressurized container 11 includes an outer container 13, a flexible inner container 14 housed therein, and a lid (sealing plate) 15 for sealing the outer container 13 and the inner container 14. consists of It has no valves or pumps. The combination of the outer container 13 and the inner container 14 is the container body 16 (see FIG. 1B). The inside of the inner container 14 is the concentrate storage chamber Sc filled with the concentrate C, and the space between the outer container 13 and the inner container 14 is the pressurizing agent accommodating chamber Sp filled with the pressurizing agent P. They are sealed by a lid 15 . That is, the double pressurization container 11 accommodates the concentrate C and the propellant P separately so that only the concentrate C can be discharged, thereby preventing leakage of the pressurizing agent P such as compressed gas.

As shown in FIG. 1B, the outer container 13 comprises a bottom portion 13a, a cylindrical body portion 13b, a shoulder portion 13c, and a cylindrical neck portion 13d. A male thread 13e is formed on the outer circumference of the neck portion 13d. An upper end surface 13f of the neck portion 13d is substantially flat so that the lid body 15 can be fixed. In this embodiment, the bottom portion 13a of the outer container 13 has a downwardly projecting annular ground surface 13a1 and an upwardly projecting dome portion 13a2 provided at the center thereof. As a result, the pressure resistance is improved, and the shock resistance at the time of dropping is also improved. Therefore, it is safe even when it is distributed as a single item or delivered by home delivery. In addition, since it has the ground surface 13a1, it can be placed stably on a flat stand or the like. However, a spherical bottom surface may be used.

As shown in FIG. 2B, the upper end surface 13f of the neck portion 13d of the outer container 13 is made integral with the lid 15 by increasing the contact pressure with the lid 15 during ultrasonic welding so as to facilitate melting. An annular protrusion 13g is formed to form a welded portion for the purpose. The annular protrusion may be provided on the lid body 15 side, or may be provided on both sides. A plurality of inclined portions 13h are provided on the inner side or the outer side of the upper end surface 13f, and a space for accommodating resin pieces formed by cooling the resin melted during ultrasonic welding so as not to protrude. becomes. An annular support portion 13d1 is provided on the outer periphery of the neck portion 13d of the outer container 13 so as to be suspended during transportation and welding.

Returning to FIG. 1B, like the outer container 13, the inner container 14 also comprises a bottom portion 14a, a body portion 14b, a shoulder portion 14c and a neck portion 14d. The bottom portion 14a of the inner container 14 is also formed with a downwardly protruding annular recess portion 14a1 and an upwardly protruding dome portion 14a2 provided at the center thereof. The outer surface of the neck portion 14d of the inner container 14 has a slight gap with the inner surface of the neck portion 13d of the outer container 13. As shown in FIG. The inner surface of the neck portion 14d of the internal container 14 is a smooth cylindrical surface. The bottom portion 14a of the inner container 14 is in contact with the bottom portion 13a of the outer container 13, and is supported so that the inner container 14 does not fall down when filling the pressurizing agent or fixing the lid 15.

As shown in FIG. 2B, the upper end surface 14e of the neck portion 14d of the inner container 14 protrudes from the upper end surface 13f of the outer container 13, and the flange 14f that engages with the upper end surface 13f of the outer container 13 is formed at the projecting portion. formed. The thickness (dimension in the radial direction) of the flange 14f is about 1/3 to 1/2 of the thickness of the neck portion 13d of the outer container 13. As shown in FIG. Therefore, when the flange 14f is engaged with the upper end surface 13f of the neck portion 13d of the outer container 13, the outer portion of the upper end surface 13f of the neck portion 13d of the outer container 13 remains uncovered. An annular projection 13g at the upper end of the outer container 13 is provided on its outer portion. An upper end surface 14e of the neck portion 14d of the inner container 14 is also formed with an annular projection 14g for forming a welded portion with the lid 15 by increasing the contact pressure with the lid 15 during ultrasonic welding. .

In the lower surface of the flange 14f of the inner container 14, four lateral grooves 14h for filling the pressurizing agent extending in the radial direction are formed at equal intervals. Further, a longitudinal groove 14i communicating with the lateral groove 14h is formed on the outer peripheral surface of the neck portion 14d of the inner container 14. As shown in FIG. The longitudinal groove 14i extends from the lateral groove 14h to the upper end of the shoulder portion 14c to facilitate filling the pressurizing agent P into the pressurizing agent storage chamber Sp.

Both the outer container 13 and the inner container 14 are made of thermoplastic resin such as polyethylene terephthalate, polyethylene naphthalate, polyethylene and polypropylene. These can be manufactured, for example, by inserting a preform for the inner container into a preform for the outer container and simultaneously blow-molding the portions below the lower ends of the necks 13d and 14d. Particularly preferred is an injection blow molding method in which a preform having a predetermined shape is injection molded and then blow molded.

As shown in FIG. 2B, the lid 15 is composed of a bottomed tubular sealing portion 15a inserted into the neck portion 14d of the internal container 14 and an annular flange 15b continuing to the upper end thereof. The lower portion of the sealing portion 15a is formed as a fitting cylindrical portion 15a1 having a diameter smaller than that of the upper portion. A closing portion (unsealable portion) 15d having a pressure receiving portion 15d1 thicker than the surrounding portion is provided at the bottom portion of the sealing portion 15a, that is, the bottom portion 15c of the fitting cylinder portion 15a1. The closing portion 15d is normally circular in plan view. However, other shapes such as rectangles can also be used.

The periphery of the closing portion 15d is surrounded by a thin portion (breaking portion, weakening line) 15f such as an annular groove that is easily broken. The pressure receiving portion 15d1 is provided on substantially the entire upper surface of the closing portion 15d, and the thin portion 15f is formed on the upper surface of the bottom portion 15c. Note that the thin portion 15f may be formed on the lower surface. Thin portion 15f is formed of, for example, a V-groove. Although the thin portion 15f is continuous, it may be discontinuous as long as it can be broken.

The outer peripheral surface of the sealing portion 15a and the inner surface of the neck portion 14d of the inner container 14 can discharge the air in the inner container 14 when the lid body 15 is attached to the neck portion 14d of the inner container 14, and , preferably in a fitted state in which the stock solution C in the inner container 14 can be liquid-sealed. A first protrusion 15m protruding radially inward is provided on the inner peripheral surface of the upper portion of the sealing portion 15a. Only one first projection 15m may be provided, or two or more may be provided in the circumferential direction. Furthermore, it may be continuous in the circumferential direction.

Basically, it is preferable that the inner peripheral surface of the fitting tube portion 15a1 be a smooth cylindrical surface so that when the closing portion 15d is unsealed, the concentrate C does not leak out due to close contact with the sealing member 28 of the valve 21. . It may have a tapered shape in which the diameter is reduced toward the bottom. However, a concave groove 15n extending in the vertical direction is provided in the upper portion of the fitting cylinder portion 15a1. The upper end of the concave groove 15n reaches the upper portion of the sealing portion 15a and communicates with the upper portion of the sealing portion 15a. On the other hand, the lower end of the concave groove 15n does not reach the bottom portion 15c, and stops at a position about 1/2 to 1/3 of the vertical length of the fitting cylinder portion 15a1. That is, the concave groove 15n is not provided in the lower portion of the fitting tube portion 15a1. This is because when the closing portion 15d is opened by the valve 21, a liquid-tight seal is already formed between the fitting cylindrical portion 15a1 and the valve 21 by the sealing member . For example, the lower end of the groove 15n may be positioned above (downstream) the position of the seal member 28 when the valve 21 first contacts the closing portion 15d. The number of concave grooves 15n may be one, or two or more.

The flange 15b of the lid body 15 is welded by ultrasonic welding, laser welding, high-frequency welding, or the like after the undiluted solution C or the pressurizing agent P is filled. It is welded and sealed to the upper end surface 14e. In this embodiment, the annular protrusion 14g is formed on the upper end surface 14e of the inner container 14, and the annular protrusion 13g is also formed on the upper end surface 13f of the outer container 13, so that the sealing after welding is assured. Moreover, you may adhere|attach for the purpose, such as raising airtightness.

The reason why the bottom portion 15c of the fitting cylinder portion 15a1 is provided slightly above the lower end of the fitting cylinder portion 15a1 is to increase the rigidity of the bottom portion 15c and facilitate breakage of the thin portion 15f. The reason why the diameter of the fitting cylinder portion 15a1 is smaller than the diameter of the upper portion of the sealing portion 15a is to improve the molding accuracy of the inner surface of the fitting cylinder portion 15a1 and to reduce the internal pressure of the discharge member 12 surrounded by the seal member 28. This is because the upward force applied to the lid body 15 is weakened by reducing the area that receives the pressure. This is to secure a space for housing the valve holding portion 18a that protrudes downward. The lower end of the cylindrical fitting portion 15a1 may be cylindrical, or may be communicated with a lateral groove so that gas does not accumulate between the lower end of the cylindrical fitting portion 15a1 and the bottom portion 15c.

The flange 15b of the lid 15 is composed of an annular disc portion 17 extending radially outward from the upper end of the sealing portion 15a and an outer cylindrical portion 17a extending downward from the outer edge of the annular disc portion 17. As shown in FIG. The lower surface of the annular disk portion 17 contacts the upper end surface 14e of the neck portion 14d of the inner container 14 to form a welded portion for sealing. It is a portion that forms a welded portion by coming into contact with and seals.

The material of the lid 15 is a thermoplastic resin having high thermal bondability with the outer container 13 and the inner container 14, and it is preferable to use the same material as the outer container 13 and the inner container 14 in order to increase the welding strength. As shown in FIG. 1A, the lid body 15 seals the undiluted solution storage chamber Sc and the pressurizing agent storage chamber Sp, and the contents ( The undiluted solution C and the pressurizing agent P) can be safely stored for a long period of time without leakage. The thin portion 15f has a sufficient sealing function in an unopened package and has a shape that can be easily broken.

Concentrate solution C includes skin products and treatment agents such as facial cleansers, detergents, bath agents, moisturizers, cleansers, sunscreens, lotions, shaving agents, hair removers, antiperspirants, disinfectants, insect repellents, etc. , Styling agents, hair products such as hair products, foods such as whipped cream and olive oil, household products such as deodorants, air fresheners, insecticides, insect repellents, pollen removers, disinfectants, etc., lubricants industrial goods such as chemicals. However, it is not limited to these uses. The undiluted solution C is preferably brought into contact with the inner surface of the closing portion 15d. As a result, the closing portion 15d is cooled by the concentrate C when the lid 15 and the container body 16 are welded together, and the problem of the closing portion 15d melting due to heat can be resolved.

As the pressurizing agent P, a compressed gas such as nitrogen gas, compressed air, or carbon dioxide gas is preferable. The pressure in the double pressurization container 11 is increased to 0.1 to 0.5 MPa (25° C., gauge pressure) by the pressurizing agent. ) is preferred. Also, the capacity of the external container 13 is preferably 30 to 500 ml. The capacity of the internal container (concentrate solution storage chamber Sc) 14 is preferably about 20 to 300 ml. The capacity of the pressurizing agent storage chamber Sp is preferably about 10 to 200 ml.

As described above, the double pressurized container 11 has a small number of parts and does not have an operating part such as a valve, so it can be manufactured at low cost. Since the pressure of the double pressurized container 11 is low and comparable to that of carbonated beverages, it is safe when carried by consumers or distributed by distributors. Further, even if the outer container 13 should crack, only the pressurizing agent P leaks, and the concentrate C in the inner container 14 does not leak. It is therefore safer.

The pressurized product 11a has an outer container 13 and an inner container 14 made of synthetic resin. It has high elasticity and does not break easily even if dropped. In addition, since the closing portion 15d is inside, there is little possibility that the closing portion 15d will be broken by mistake, which makes it even safer.

The discharge member 12 includes a cap (mounting portion) 20A screwed onto the external thread 13e of the neck portion 13d of the outer container 13, a valve 21 covered with the cap 20A, and an exterior component 70 (see FIG. 5). there is As shown in FIG. 2A, the cap 20A is a so-called screw cap that has a cylindrical shape with a bottom and a female thread formed on the inner peripheral surface. Therefore, the cap 20A can be attached to and detached from the pressurized product 11a. Further, the valve 21 attached to the pressurized product 11a by the cap 20A is also automatically removed from the pressurized product 11a when the cap 20A is removed from the pressurized product 11a. That is, the valve 21 is also detachable from the pressurized product 11a. The cap 20A and the valve 21 are integrated, and the valve 21 moves in the fitting cylindrical portion 15a1 in conjunction with the tightness of the cap 20A. That is, when the cap 20A is tightened, the valve 21 is pushed into the fitting tube portion 15a1, and when the cap 20A is loosened, the valve 21 moves in a direction to be extracted from the fitting tube portion 15a1. An opening 20b through which the stem 22 and the base of the button 73 are passed is formed in the center of the upper base 20a of the cap 20A. A second claw portion 20c is provided on the outer surface of the cap 20A (see FIG. 5A). The cap 20A and valve 21 are treated as a valve unit or valve assembly.

The valve 21 comprises a cylindrical housing 24 with a bottom, the aforementioned stem 22 housed therein so as to be vertically movable, a spring 25 for urging the stem 22 upward, a stem rubber 26, and the housing 24. It is composed of a valve holder 18 having a cylindrical valve holding portion 18a for holding the upper portion thereof, and constitutes a discharge passage for the undiluted solution C. As shown in FIG. The stem 22, the spring 25, and the stem rubber 26 constitute a valve mechanism for switching between a discharge state and a non-discharge state of the concentrate C, and the housing 24 and the valve holder 18 define a housing space for housing this valve mechanism. Configure.

In this embodiment, the lower end of the housing 24 is provided with a cylindrical opening portion 27 protruding downward, and a sealing member 28 such as an O-ring is attached to the outer circumference of the lower portion of the housing 24 . This sealing member 28 seals between the inner peripheral surface of the fitting cylindrical portion 15a1 of the lid 15 and the housing 24 during and after opening. Since the seal member 28 is compressed between the inner surface of the fitting tube portion 15a1 and the outer surface of the housing 24, which are spaced substantially equally apart in the vertical direction, the sealing can be maintained even if the seal member 28 moves in the vertical direction to some extent. . A bottom surface 27a of the opening portion 27 is flattened so as to abut on the upper surface of the pressure receiving portion 15d1.

In this embodiment, the opening portion 27 has a diameter somewhat smaller than the pressure receiving portion 15d1. Moreover, it is somewhat smaller than the diameter of the range surrounded by the thin portion 15f. As a result, when broken, the bottom surface 27a of the unsealable portion 27 does not come into contact with the outer peripheral portion rather than the thin portion 15f of the bottom portion 15c, preventing the pressing of the pressure receiving portion 15d1 from being hindered. In addition, after breaking, the bottom surface 27a of the unsealing portion 27 can be projected downward from the opening formed by unsealing, thereby facilitating the securing of the passage for the concentrate C (see FIG. 3A). A plurality of reinforcing plates 27 d are radially provided between the cylindrical opening portion 27 and the lower surface 24 a of the housing 24 . The number of reinforcing plates 27d is preferably three to five. The reinforcing plate 27d has a substantially triangular shape when viewed from the side, and its lower end does not reach the lower end of the unsealable portion 27, and the vicinity of the lower end of the unsealable portion 27 remains cylindrical.

The housing 24 is provided with a vertical hole 24c penetrating vertically through a bottom plate 24b of the housing 24 as a passage for communicating the interior of the housing 24 and the concentrate storage chamber Sc in the internal container 14 . Vertical holes 24c are formed between adjacent reinforcing plates 27d. Therefore, the reinforcing plate 27d does not hinder the discharge of the contents. The vertical holes 24c are formed in the same number as the reinforcing plates 27d. However, it may be less than that, such as one or two. The planar shape of the vertical hole 24c can be, for example, substantially fan-shaped. It is preferable to provide a plurality of vertical holes 24c. As a result, even if one vertical hole 24c is blocked, it can be communicated with another vertical hole 24c.

The position in the height direction of the bottom surface 27a of the unsealing portion 27 is the position at which the cap 20A comes into contact with the pressure receiving portion 15d1 when the cap 20A is screwed onto the male thread 13e of the outer container 13 once or twice. Accordingly, the cap 20A can be loosely screwed during shipping and distribution to temporarily connect the discharge member 12 and the double pressurization container 11 in a sealed state without breaking the closing portion 15d.

The valve holder 18 includes a valve holding portion 18a, an annular rubber retainer 18b extending inwardly from the upper end of the valve holding portion 18a, and a flange 18c extending outward. 18d are formed. A second projection 18i projecting radially outward is provided on the outer peripheral surface of the valve holding portion 18a. The projection length of the second projection 18i is determined so that it can come into contact with the first projection 15m. The number of second protrusions 18i may be one, or two or more may be provided in the circumferential direction. Also, the second protrusions 18i may be continuous in the circumferential direction.

When using the discharge device 10 purchased by the user, the cap 20A is first screwed onto the external thread 13e of the outer container. As a result, the entire cap 20A and the valve 21 are lowered, and the bottom surface 27a of the opening portion 27 pushes down the closing portion 15d. As a result, the thin portion 15f is broken and the pressurized product 11a is unsealed. A portion of the closing portion 15d remains connected to the bottom portion 15c, or is torn off from the fitting tube portion 15a1, separated from the bottom portion 15c, and dropped. The unsealing portion 27 breaks through the bottom portion 15c of the fitting tube portion 15a1 to allow communication between the inside of the housing 24 and the concentrate storage chamber Sc inside the internal container 14 (see FIG. 3A). The dropped closing portion 15d falls to the bottom of the inner container 14. As shown in FIG.

Since the cap 20A is screwed to the outer container 13, the amount of descent of the valve 21 relative to the amount of operation of the cap 20A is small. Therefore, the bottom surface 27a of the opening portion 27 gradually presses the pressure receiving portion 15d1 of the closing portion 15d. Since the lid body 15 is made of synthetic resin, when it is gradually pressed, the closing part 15d tends to stretch due to its extensibility and is hard to break. However, in this embodiment, the closing portion 15d is surrounded by the annular thin portion 15f, and the pressure-receiving portion 15d1 protrudes, so that the stress concentration on the thin portion 15f is increased, so that the thin portion 15f can be broken smoothly. Further, since the bottom surface 27a of the unsealing portion 27 is flat, it is not easily deformed by the unsealing operation, and the ejection member 12 can be used repeatedly.

The closing portion 15d has a thick, substantially circular pressure-receiving portion 15d1 provided on the central axis of the lid 15, and is in contact with the circular bottom surface 27a of the opening portion 27. When pressed, the closing portion 15d is pushed straight and breaks along the thinned portion 15f. However, the pressure receiving portion 15d1 or the bottom surface 27a of the opening portion 27 may be inclined so that the thin portion 15f is broken from one side to the other side.

When the closed portion 15d is broken, the concentrate C may leak from the gap between the inner circumference of the bottom portion 15c and the outer circumference of the opening portion 27. However, downstream of the closing portion 15d, the sealing member 28 seals between the fitting cylinder portion 15a1 and the housing 24, so the undiluted solution C stays in the fitting cylinder portion 15a1 and does not leak to the outside. In addition, the reaction force at the time of breakage and the internal pressure after the breakage act to push up the housing 24, but the cap 20A and the outer container 13 are screwed together, and the upper base 20a of the cap 20A and the valve holder 18 are double-layered. , the discharge member 12 is restrained from protruding. In this state, it can be said that the valve 21 is attached by the cap 20A. Also, deformation of the upper base 20a of the cap 20A is suppressed.

After mounting the discharge member 12, when the user presses a button 73 (see FIG. 5) attached to the stem 22, the stem 22 descends, the stem rubber 26 bends, and the stem hole opens. Since the concentrate C in the concentrate storage chamber Sc is pressurized by the pressurizing agent P through the inner container 14 , it is discharged to the outside via the opening portion 27 , the housing 24 , the stem 22 and the button 73 . When the finger is released from the button 73, the stem 22 rises and the discharge stops. The pressurizing agent storage chamber Sp filled with the pressurizing agent P is closed by the lid 15 and is not communicated with the outside or the undiluted liquid storage chamber Sc. no.

After the liquid concentrate C is completely discharged, the external component 70 is removed upward, the cap 20A is turned, and the discharge member 12 is removed from the pressurized product 11a. Then, the removed discharge member 12 is attached to a new pressurized product 11a. In the pressurized product 11a from which the stock solution C has been completely discharged, the pressurizing agent P remains in the pressurizing agent storage chamber Sp. It is gradually released to the outside from the portion 15d. Since the pressurized container 11 is easily deformed when the pressurizing agent P is released to the outside, it is easily understood by consumers, and the pressurized container 11 can be safely recycled. In addition, since the cover 15 and the container body 16 of the pressurized container 11 can be made of a single material, there is no need to separate them when recycling them, which facilitates recycling.

In the double pressurized container 11 shown in FIG. 4A, a substantially cylindrical sealing portion 15a extends downward, and a fitting cylindrical portion 15a1 is concentrically provided inside the sealing portion 15a. The fitting tube portion 15a1 rises upward from the central portion of the bottom portion of the sealing portion 15a and is open at the upper end. The upper portion of the sealing portion 15a is substantially cylindrical, and the lower portion 15a3 is tapered downward. However, it may be cylindrical from top to bottom.

On the other hand, the neck portion 14d of the inner container 14 is shaped so as to be in close contact with the outer peripheral surface of the sealing portion 15a, and has a cylindrical upper portion 14d1, a tapered portion 14d2 that tapers downward, and and a downwardly extending cylindrical portion 14d3. The lower end of the cylindrical portion 14d3 is continuous with the shoulder portion 14c. That is, the tapered portion 14d2 of the neck portion 14d of the inner container 14, the cylindrical portion 14d3 and the upper portion of the shoulder portion 14c form a constricted portion.

It is the same as the double pressurized container 11 in FIG. 2A in that a closed portion (openable portion) 15d surrounded by a weakening line 15f is provided on the bottom portion 15c of the fitting cylinder portion 15a1. However, in the double pressurization container 11 of FIG. 4A, a notch 15h is provided on the outer circumference of the upper surface of the lid 15. As shown in FIG. The notch 15h facilitates concentration of the vibration of the horn on the annular projection 13g at the upper end of the neck portion of the outer container 13 when the horn is pressed against the upper surface of the lid 15 for ultrasonic welding.

The cover 15 of FIG. 4A is provided with a fitting tubular portion 15a1 inside the sealing portion 15a, and has a lower end 15a4 of the tapered lower portion 15a3 and a lower tubular portion 15a5 extending downward from the fitting tubular portion 15a1. is connected to the lower end of the by a connecting portion 15a6. Further, the closing portion 15d is provided on the bottom portion 15c that closes the lower end of the lower cylindrical portion 15a5. Therefore, when ultrasonic welding is performed by pressing the horn against the upper surface of the lid 15, the vibration of the horn easily flows through the sealing portion 15a and flows from the lower end 15a4 to the concentrate C side. Further, since the closing portion 15d is provided above the connecting portion 15a6, vibration is less likely to be transmitted to the closing portion 15d. Therefore, the weakening wire 15f is prevented from being melted or penetrated.

The double pressurized container 11 of FIG. 4A has a neck portion 14d of the inner container 14 formed with a tapered portion 14d2 and a cylindrical portion 14d3, and the constricted portion is in close contact with the sealing portion 15a of the lid 15. Therefore, when the stock solution C is filled in the inner container 14, the gas phase portion Gp (head space) becomes small. Therefore, when the consumer starts to use the concentrate C, the gas compressed in the gas phase part Gp causes the concentrate C to be vigorously discharged and splashed. Problems such as sagging are less likely to occur, and ejection becomes smoother. In particular, a post-foaming gel composition or a post-foaming cream composition containing a foaming agent such as isopentane or 1-chloro-3,3,3-trifluoropropene having a boiling point of 10 to 35°C in the stock solution is used. Even when filled, foaming immediately after filling can be prevented due to the small gas phase portion Gp, and gel or cream can be discharged.

In the double pressurized container 11 of FIG. 4A, the neck portion 14d of the inner container 14 and the lower portion 15a3 of the sealing portion 15a of the lid 15 may be straight cylindrical. However, providing a neck portion 14d of the inner container 14 with a constricted portion and tapering the lower portion 15a3 of the sealing portion 15a of the lid 15 is preferable because the diameter and volume of the gas phase portion Gp can be reduced. Further, if a rib 15p is provided on the tapered lower portion 15a3 to press against the tapered portion 14d2 of the neck portion of the inner container so that a line seal is formed when the lid 15 is put on the container body 16, the pressurizing agent can be It is possible to prevent mixing into the internal container 14 when filling P, and even if the undiluted solution C is atomized by ultrasonic vibration when the lid 15 is welded, the tapered lower part 15a3 and the internal container Outflow to the welding portion side from the gap between the neck portion and the tapered portion 14d2 is prevented, and the welding is not hindered. Instead of the rib 15p, the outer peripheral surface of the tapered lower portion 15a3 may be formed in a spherical shape and brought into contact with the tapered portion 14d2 of the neck to form a line seal.

By the way, the ejection device 10 of FIGS. 3B and 4B has a concave groove 15n in the lid 15. As shown in FIG. When the seal member 28 is positioned in the groove 15n, the compression of the seal member 28 by the inner surface of the lid 15 (fitting cylindrical portion 15a1) and the outer surface of the valve 21 (housing 24) is relaxed in the portion overlapping the groove 15n. In this state, it can be said that the sealing by the sealing member 28 is partially released by the concave groove 15n. Therefore, the undiluted solution C leaks out of the internal container 14 through the concave groove 15n. The leaked stock solution C leaks out of the discharge device 10 through between the lid 15 and the valve holder 18 and between the inner surface of the cap 20A and the outer surface of the neck portion 13d of the external container 13. FIG. Since the leaked stock solution C leaks out slowly and without force, it does not scatter around, and can be attached to the hands of a person who tries to remove the cap 20A or can be visually recognized.

The sealing member 28 is positioned below (upstream) the groove 15n before loosening (starting to remove) the cap 20A, that is, when the cap 20A is completely attached to the pressurized product 11a. Therefore, the undiluted solution C does not leak out from the concave groove 15n. On the other hand, when the cap 20A is loosened (starts to be removed), the valve 21 as a whole moves upward, and before the cap 20A is removed from the pressurized product 11a (the cap 20A is still screwed onto the male thread 13e). The sealing member 28 reaches the recessed groove 15n and the undiluted solution C begins to leak (see arrows in FIGS. 3B and 4B). In this manner, the ejection device having the above configuration includes a partial release mechanism Re that partially releases the sealing by the sealing member 28 by moving the valve 21 caused by loosening (starting to remove) the cap 20A. Therefore, the leakage of the concentrate C can inform the user that the concentrate C still remains, and the cap 20A can be prevented from being removed while the concentrate C remains. If the cap 20A is retightened when the leakage of the concentrate C is noticed, the sealing member 28 will be positioned below (upstream) the groove 15n, the leakage of the concentrate C will stop, and the seal member 28 can be reused. can.

Further, the lid 15 has a first projection 15m, and the valve 21 has a second projection 18i. When the cap 20A is completely attached to the pressurized product 11a (before loosening (starting to remove) the cap 20A), the second projection 18i is positioned below the first projection 15m as shown in FIG. 3A. , the first projection 15m and the second projection 18i are not in contact with each other. On the other hand, when the cap 20A is loosened (begins to be removed), the entire valve 21 moves upward and the first projection 15m and the second projection 18i come into contact before the cap 20A is removed from the pressurized product 11a. . Therefore, it becomes difficult to turn the cap 20A. The timing at which it becomes difficult to turn is matched with the timing at which the stock solution C leaks out from the concave groove 15n. The degree of loosening (the degree of removal: the number of rotations and the angle of rotation) of the cap 20A when the seal member 28 reaches the groove 15n (when the partial release mechanism Re operates) should be equal. This makes it easier for the user to feel uncomfortable, and it is possible to further prevent the user from removing the cap 20A while the concentrate C remains.

Since other configurations are the same as those of the ejection device 10 of FIG.

The discharge device 10 of FIG. 5 shows a state in which an external component 70 is attached. The external component 70 includes a cover portion 71 attached to the cap 20A, a nozzle 72 attached to the stem 22, and a button 73 for pushing down the stem 22 via the nozzle 72 (injection operation).

The cover portion 71 includes a lower tubular portion 71a that covers the cap 20A, an upper tubular portion 71b that extends upward from the upper end of the lower tubular portion 71a, a lid portion 71c that covers the upper tubular portion 71b, the lower tubular portion 71a and the upper tubular portion 71b. A partition wall 71d that partitions the cylindrical portion 71b and a support cylinder 71e rising from the partition wall 71d are provided. The lower tubular portion 71a has a substantially cylindrical shape and an inner diameter substantially equal to the outer diameter of the cap 20A. The upper cylindrical portion 71b has a substantially cylindrical shape and gradually increases in diameter upward. The lid portion 71c has a cylindrical shape with a bottom, and has an open bottom end. An engagement stepped portion 71c1 that engages with the upper end of the upper tubular portion 71b is provided at the lower end portion. The partition wall 71d is substantially disc-shaped, and has a through hole 71d1 for allowing the nozzle 72 and the stem 22 to pass through in the central portion. The support tube 71e has a substantially cylindrical shape and extends upward from around the through hole 71d1.

The nozzle 72 is provided with a passage 72a for passing the stock solution C inside. The nozzle 72 has a vertical portion 72b extending upward and a horizontal portion 72c extending horizontally from the upper end of the vertical portion 72b. The lower end of the vertical portion 72b is detachably attached to the stem 22. As shown in FIG. Therefore, it can be removed from the stem 22 and washed. The internal passage 72a communicates with the stem 22. As shown in FIG. The passage 72a opens at the tip of the lateral portion 72c. An injection nozzle 72d having an injection hole is attached to the tip of the horizontal portion 72c.

The button 73 includes a bottomed tubular pressing portion 73a and a cylindrical cover tube 73b extending downward from the center of the pressing portion 73a. The pushing portion 73a is engaged with the lateral portion 72c of the nozzle 72, and the stem 22 can be pushed through the nozzle 72 by pushing the pushing portion 73a. Moreover, when the nozzle 72 is removed from the stem 22, the nozzle 72 is removed together with the stem 22.例文帳に追加The cover tube 73b is slidably fitted on the support tube 71e, and suppresses the vibration of the button 73 when the pressing portion 73a is pushed.

FIG. 5B shows a state in which the cap 20A is covered with the lower tubular portion 71a. As shown in the figure, a first claw portion 71a1 is provided on the inner peripheral surface of the lower cylindrical portion 71a, and a second claw portion 20c is provided on the outer peripheral surface of the cap 20A. The first claw portion 71a1 and the second claw portion 20c are engaged with each other only when the cover portion 71 (lower cylindrical portion 71a) is rotated, for example, clockwise with respect to the shaft of the cap 20A. Specifically, the first claw portion 71a1 and the second claw portion 20c each have a serrated shape, and are engaged with each other in the clockwise direction, but the first claw portion 71a1 engages the second claw portion 20c in the counterclockwise direction. They get over each other and don't get caught on each other. Therefore, when the cover portion 71 is turned clockwise, the cap 20A is also turned clockwise. On the other hand, when the cover portion 71 is rotated counterclockwise, the first claw portion 71a1 and the second claw portion 20c are not engaged. Therefore, even if the cover portion 71 is rotated counterclockwise, the cap 20A does not rotate, and only the cover portion 71 rotates idle. That is, a ratchet mechanism Ra that rotates together in only one direction is constituted by the lower tubular portion 71a and the cap 20A. The co-rotating direction is the same as the tightening direction of the cap 20A. Therefore, even if the cover part 71 is turned, the cap 20A cannot be turned in the direction of loosening (removing), and the removal of the cap 20A from the pressurized product 11a can be suppressed. On the other hand, since the cap 20A can be tightened by turning the cover portion 71, the external product 70 is put on the pressurized product 11a with the cap 20A and the valve 21 in the lower cylindrical portion 71a, and the external product 70 is closed. The pressurized product 11a can be opened by turning it.

To discharge the concentrate C, first, the engagement between the upper cylindrical portion 71b and the lid portion 71c is released, and the lid portion 71c is removed. Then, by pressing the exposed button 73 downward, the stem 22 is pushed down through the nozzle 72 , and the concentrate C is discharged from the nozzle 72 . After the liquid concentrate C has been completely discharged, the external component 70 is removed upward, the cap 20A is turned, and the valve 21 is removed from the pressurized product 11a. Then, the removed discharge member 12 (cap 20A, valve 21, seal member 28, outer package 70) is attached to a new pressurized product 11a.

Since other configurations are the same as those of the ejection device 10 shown in FIGS. 2 and 4, the same reference numerals are given and description thereof is omitted.

In the discharge device 10 of FIG. 6, the cover portion 71B has an engaging portion 71a3 that engages the cover portion 71B with the cap 21B so as to be rotatable around the axis of the cap 20B. Specifically, first, the lower cylindrical portion 71a of the cover portion 71B has a plurality of engaging pieces 71a2 extending downward, and engaging protrusions (engaging projections) provided inside the engaging pieces 71a2. part) 71a3. The engaging protrusion 71a3 is engaged with the lower end of the cap 21B, and the lower end of the cap 21B is flat and smooth. Therefore, even if the cover portion 71B is rotated around the axis of the cap 21B, the engaging projection 71a3 will not be caught on the cap 21B in the rotational direction. In other words, the engagement projection 71a3 prevents the cover portion 71B from coming off the cap 21B, and does not restrict the rotation of the cover portion 71B. In addition, it can be said that a slit is provided between the engaging pieces 71a2, 71a2, and the engaging piece 71a2 is easily deformed in the radially outward direction of the lower cylindrical portion 71a, and the engaging projection 71a3 is positioned at the lower end of the cap 21B. It is easy to engage with.

The engagement piece 71a2 is covered with a skirt portion 71a4 extending downward from the base end of the engagement piece 71a2. The skirt portion 71a4 is continuous in the circumferential direction and extends to the vicinity of the shoulder portion 13c of the outer container 13 beyond the engaging piece 71a2.

By the way, the ejection device 10 of FIG. 6 also has a ratchet mechanism Ra. However, unlike the ejection device 10 of FIG. 5A, the first claw portion 71a1 is provided on the upper portion of the lower tubular portion 71a (near the lower surface of the partition wall 71d), and the second claw portion 20c is provided on the upper portion of the cap 21B (near the partition wall 71d). (near the bottom surface of the ). The mechanism is similar to that of FIGS. 5A and 5B. That is, the first claw portion 71a1 and the second claw portion 20c are engaged with each other in the direction of tightening (attaching) the cap 21B, and the first claw portion 71a1 and the second claw portion 20c are engaged with each other in the direction of loosening (removing) the cap 21B. does not engage with Therefore, even if the cover portion 71B is rotated around the axis of the cap 21B, the cap 21B is not loosened (disengaged). On the other hand, in order to open the unopened pressurized product 11a, the cap 21B and the cover portion 71B are placed on the pressurized product 11a with the cap 21B inserted in the lower cylindrical portion 71a, and the cover portion 71B is capped. 21B should be rotated in the tightening direction. At this time, since the engaging projection 71a3 is engaged with the lower end of the cap 21B, the cap 21B can be prevented from falling off from the cover portion 71B, which facilitates the work.

After discharging the whole amount of the stock solution C, first, the outer package 70 is removed upward. The engagement protrusions 71a3 are engaged with the lower end of the cap 21B, but there are several engagement protrusions 71a3 and the engagement pieces 71a2 are separated from each other, so the engagement can be released with a relatively small force. can do. The cap 20B is then turned to remove the valve 21 from the pressurized product 11a. Then, the removed discharge member 12 (cap 20B, valve 21, seal member 28, outer package 70) is attached to a new pressurized product 11a.

Other configurations are the same as those of the ejection device 10 of FIG.

Figures 7 and 8 show a dispensing device 10 that does not use a screw cap as the cap. As shown in FIG. 7A, the inner peripheral surface of the cap 20C is not threaded, and as shown in FIG. 7B, the neck portion 13d of the outer container 13A is also not threaded. In the discharge device 10, the cap 20C is locked to the outer container 13A by the groove portion 13j and the engaging projection 20d that engages with the groove portion 13j.

The groove portion 13j is provided on the outer peripheral surface of the neck portion 13d of the outer container 13A. The groove portion 13j includes a vertical groove 13j1 extending downward from the upper end of the neck portion 13d, a lateral groove 13j2 extending laterally from the lower end of the vertical groove 13j1, and a holding portion 13j3 recessed upward at the terminal end of the lateral groove 13j2. I have. A plurality of grooves 13j are preferably provided. Moreover, it is preferable that they are provided at regular intervals.

20 d of engaging protrusions are provided in the lower part of the internal peripheral surface of the cap 20C. The engaging projection 20d protrudes radially inward, and the radially inward tip of the engaging projection 20d is located radially inward of the outer peripheral surface of the neck portion 13d (excluding the groove portion 13j). It is preferable that a plurality of engaging protrusions 20d are provided. For example, it is preferable to provide the same number as the grooves 13j. Moreover, it is preferable that they are provided at the same intervals as the grooves 13j.

To attach the cap 20C to the outer container 13A, first, the positions of the engagement projection 20d and the longitudinal groove 13j1 are aligned. Then, the cap 20C is pushed down. When the cap 20C is pushed down, the closing portion 15d of the lid 15 is pushed by the opening portion 27 of the valve 21, and the pressurized product 11a is opened. After opening, the cap 20C is rotated around the axis to move the engaging projection 20d from the vertical groove 13j1 to the horizontal groove 13j2. After the pressurized product 11a is opened, the valve 21 receives the pressure of the pressurizing agent P, but the cap 20C does not come off from the pressurized product 11a by positioning the engaging projection 20d in the lateral groove 13j2. If the engaging projection 20d is positioned in the holding portion 13j3, the engaging projection 20d is fitted in the recess, and the rotation of the cap 20C around the axis is also suppressed.

By the way, the vertical groove 13j1 is provided with a locking projection 13k. The locking projection 13k does not or hardly gets caught when the cap 20C is pushed down, but gets caught in the direction in which the cap 20C is removed. Specifically, the upper surface is gently slanted with respect to the outer peripheral surface of the neck portion 13d, and the lower surface is steeply slanted. The position of the locking projection 13k in the vertical direction is determined so that it engages with the engaging projection 20d at a position where the partial release mechanism Re by the groove 15n and the seal member 28 operates. Therefore, even if the engagement protrusion 20d is positioned in the vertical groove 13j1 after the pressurized product 11a is opened (even if the cap 20C is started to be removed from the pressurized product 11a), the cap 20C is immediately removed from the pressurized product 11a. There is no problem, and it is once stopped by the locking projection 13k. At this time, if the concentrate C remains in the inner container 14, the concentrate C slightly leaks out of the ejection device 10 by the partial release mechanism Re. Even if the partial release mechanism Re is activated, the ejection device 10 can be used continuously by pressing the cap 20C again. After all the concentrate C has been discharged, the concentrate C will not leak out. In this case, the cap 20C and the valve 21 can be removed from the pressurized product 11a by strongly pulling the cap 20C upward to release the engagement between the locking projection 13k and the engaging projection 20d. The removed discharge member 12 can be attached to a new pressurized product 11a.

In the discharge device 10, the lid 15 is not provided with the first protrusion 15m, and the valve holder 18 is not provided with the second protrusion 18i. Since other configurations are the same as those of the ejection device 10 of FIG.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made within the scope of the invention. For example, the groove 15n may be provided in the valve 21 and the sealing member 28 may be attached to the lid 15. FIG. In this case, the concave groove 15n is provided downward. As the cap 20A is loosened and the valve 21 gradually moves upward, the sealing member 28 reaches the groove 15n and the concentrate C leaks out through the groove 15n.

7 and 8, the cap 20C may be provided with the groove 13j and the locking projection 13k, and the outer container 13A may be provided with the engaging projection 20d. Even in this case, the same effect can be obtained.

5 and 7 and the pressurized product 11a shown in FIGS. 2, 4 and 7 can be freely combined. For example, if a second claw portion 20c is provided on the outer surface of the cap 20C of FIG. 7 in the same manner as the caps 20A and 20B, and the exterior component 70 shown in FIGS. A rotating ratchet mechanism Ra is constructed. If the co-rotating direction is the same as the direction from the vertical groove 13j1 to the holding portion 13j3, the cap 20C can be rotated even if the cover portion 71 is turned in the direction from the holding portion 13j3 to the vertical groove 13j1 (that is, the direction to remove the cap 20C). cannot be removed, and removal of the cap 20C from the pressurized product 11a can be suppressed. On the other hand, since the cover portion 71 can be turned in the direction from the longitudinal groove 13j1 toward the holding portion 13j3, the external product 70 is placed over the pressurized product 11a while the cap 20C and the valve 21 are placed in the lower cylindrical portion 71a. , the cap 20C can be attached to the pressurized product 11a by turning the outer package 70. As shown in FIG. Also, the cap 20C and the external container 13A of FIG. 7 may be applied to the discharge device 10 of FIG.

Also, although the lid body 15 is welded to both the inner container 14 and the outer container 13, it may be fixed to one of them and simply sealed to the other with an O-ring or the like. Further, in the above embodiment, the inner container 14 and the outer container 13 are manufactured by blow molding at the same time. The inner container may be blow molded within the molded outer container. Although the cylinder-shaped opening portion 27 is used in the above-described embodiment, it may be rod-shaped such as a prism.
