[0023] FIG. [Figure 4]2 is an explanatory view showing a state in which the liquid content is being discharged in the form of a mist from a discharge hole of the discharge container shown in FIG. 1.
[0023] FIG. [Figure 5] 2 is an explanatory view showing a state in which a small amount of liquid content is being discharged from a discharge hole of the discharge container shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION
[0012] Hereinafter, the configuration of a discharge container according to an embodiment of the present invention will be described in detail with reference to the drawings.
[0013] As shown in FIG. 1, a discharge container 1 according to one embodiment of the present invention has a container body 10 and a discharge tool 20.
[0014] In the claims and this specification, the up-down direction refers to the up-down direction when the discharge container 1 is in an upright position with the discharge tool 20 positioned above the container body 10, as shown in Figure 1.
[0015] The container body 10 is a synthetic resin bottle having a mouth 11 and a body 12, and can contain a liquid content 2, such as a liquid food seasoning, such as vinegar. The mouth 11 is cylindrical with its center at axis O, and has an annular locking protrusion 13 integrally formed on its outer periphery. The body 12 is cylindrical with a bottom, and can be elastically deformed by being squeezed (pressed) to reduce the content volume.
[0016] The discharge tool 20 has a cap body 21 , an inner lid 22 and an upper lid 23 , and is attached to the mouth portion 11 of the container body 10 .
[0017] The cap body 21 has a discharge port 21 a and is attached to the mouth portion 11 .
[0018] More specifically, the cap body 21 is made of synthetic resin and has a peripheral wall 21b and a lip portion 21c integral with the peripheral wall 21b. An annular groove 21d that opens downward is provided on the inside of the peripheral wall 21b, and a plurality of locking claws 21e are provided at intervals in the circumferential direction at the lower end of the annular groove 21d. The cap body 21 is attached to the mouth portion 11 by fitting the annular groove 21d into the mouth portion 11 and by undercut-engaging the plurality of locking claws 21e with the locking projections 13. In addition, a slit groove is provided in the peripheral wall 21b when viewed from above, resulting in a double-wall structure.
[0019] The cap body 21 is provided with a stopper 21f that closes the discharge port 21a. The stopper 21f is integrally connected to the inner peripheral edge of the discharge port 21a via an annular weakened portion 21g that is thinner than the cap body 21 and the stopper 21f. By providing the stopper 21f on the cap body 21, it is possible to prevent the content liquid 2 contained in the container body 10 from leaking out of the discharge port 21a during distribution.
[0020] A pull ring 21h is provided integrally with the stopper 21f, and when starting to use the discharge container 1, the pull ring 21h is pulled up to break the weakened portion 21g, thereby removing the stopper 21f and opening the discharge outlet 21a. When the discharge outlet 21a is opened, the discharge container 1 can discharge the content liquid 2 contained in the container body 10 from the discharge outlet 21a to the outside by tilting the container body 10. The content liquid 2 is guided by the lip portion 21c.
[0021] The inner lid 22 has a spin groove 22a that is connected to the discharge port 21a and a discharge hole 22b that is connected to the spin groove 22a, and is provided so as to be able to be opened and closed relative to the cap body 21.
[0022] More specifically, the inner lid 22 is made of synthetic resin and has a cylindrical lid body 22e with a peripheral wall 22c and a top wall 22d. The peripheral wall 22c of the lid body 22e is connected to the peripheral wall 21b of the cap body 21 by a first hinge 24. A flange functioning as an operating piece is provided on the peripheral wall 21b on the opposite side of the first hinge 24. The first hinge 24 is configured as a bent thin plate and is deformable so that the bending angle can be changed. As a result, the inner lid 22 rotates relative to the cap body 21 about the first hinge 24, allowing it to be opened and closed between a closed state relative to the cap body 21 as shown in FIG. 1 and an open state relative to the cap body 21 as shown in FIG. 3. The inner lid 22 is maintained in a closed state relative to the cap body 21 by undercut engagement of the peripheral wall 22c with an engagement wall provided on the peripheral wall 21b of the cap body 21.
[0023] In this embodiment, the lid main body 22e of the inner lid 22 is formed integrally with the cap main body 21 together with the first hinge 24 by injection molding of a synthetic resin material. Note that the lid main body 22e of the inner lid 22, the cap main body 21, and the first hinge 24 may be formed separately and then assembled together.
[0024] As shown in FIG. 1, a sealing tube 22f is integrally formed on the underside of the top wall 22d. When the inner lid 22 is closed on the cap body 21, the sealing tube 22f is in liquid-tight contact with the inner peripheral surface of the lip portion 21c over the entire circumference, forming a flow path for the content liquid 2 between the cap body 21 and the lid body portion 22e. A cylindrical mounting tube 22g centered on the axis O is integrally formed on the upper surface of the top wall 22d, and a shaft 22h is provided inside the mounting tube 22g. Furthermore, a plurality of communication holes 22i penetrating the top wall 22d are formed in the base portion of the shaft 22h. The communication holes 22i are in communication with the discharge port 21a via a flow path between the cap body 21 and the lid body portion 22e.
[0025] A nozzle cap 22j having a cylindrical shape with a top is attached to the attachment tube 22g. The nozzle cap 22j has a cylindrical inner tube portion 22k centered on the axis O, and the inner tube portion 22k is fitted to the outside of the shaft body 22h. A plurality of inlet grooves 22m extending along the axis O are provided on the inner peripheral surface of the inner tube portion 22k at intervals in the circumferential direction, and the plurality of outlet grooves 22n communicating with the corresponding inlet grooves 22m are provided on the outer peripheral surface of the shaft body 22h at intervals in the circumferential direction. In addition, a pair of spin grooves 22a is provided at the tip of the shaft body 22h. The pair of spin grooves 22a are arranged point-symmetrically and parallel to each other across the axis O when viewed from the direction of the axis O, and each communicates with a circular outlet chamber 22q centered on the axis O at a position radially outwardly shifted from the axis O. The pair of spin grooves 22a communicate with the respective outflow grooves 22n via annular grooves 22r formed between the shaft body 22h and the inner surface of the top wall 22s of the inner cylindrical portion 22k. In this embodiment, the spin grooves 22a are formed at the tip of the shaft body 22h and provided between the shaft body 22h and the inner surface of the top wall 22s of the inner cylindrical portion 22k, but they may be formed on the nozzle cap 22j side (the inner surface of the top wall 22s where the discharge hole 22b is provided) or any other location as long as they are provided between the shaft body 22h and the inner surface of the top wall 22s of the inner cylindrical portion 22k.
[0026] The nozzle cap 22j has a discharge hole 22b. The discharge hole 22b is circular and centered on the axis O, and is connected to the spin groove 22a via the outflow chamber 22q. The spin groove 22a is connected to the discharge port 21a of the cap body 21 via the annular groove 22r, the outflow groove 22n, the inflow groove 22m, and the communication hole 22i. Therefore, when the stopper 21f is removed, the content liquid 2 contained in the container body 10 can flow to the discharge hole 22b through the discharge port 21a, the communication hole 22i, the inflow groove 22m, the outflow groove 22n, the annular groove 22r, the spin groove 22a, and the outflow chamber 22q.
[0027] The nozzle cap 22j may be configured to be integral with a cover body 22t having a generally truncated cone shape. The nozzle cap 22j may also be configured such that its rotation about the axis O relative to the lid main body 22e is restricted by a rotation stopper 22u provided between the nozzle cap 22j and the peripheral top wall 22d of the lid main body 22e.
[0028] The discharge tool 20 may also be configured such that a slit valve 25 is provided between the discharge port 21a and the spin groove 22a. In this embodiment, a cylindrical fixed tube 26, which is centered on the axis O and surrounds the flow hole 22i, is integrally provided on the underside of the top wall 22d of the lid main body 22e of the inner lid 22, and the slit valve 25 is integrally provided on the inner circumferential surface of a tubular body 27 fitted and fixed to the fixed tube 26. The tubular body 27 and the slit valve 25 are integrally molded products made of synthetic resin by injection molding, and may also be integrally formed from an elastic body such as synthetic rubber. The slit valve 25 is a thin membrane that closes the internal passage of the tubular body 27 and has an openable and closable slit 25a. In the natural state, the slit valve 25 has the slit 25a closed to block the flow path between the flow hole 22i or spin groove 22a and the discharge outlet 21a, and when the body 12 of the container body 10 is squeezed and the pressure of the content liquid 2 flowing out from the discharge outlet 21a is applied, the slit 25a opens, allowing the content liquid 2 to flow from the discharge outlet 21a to the flow hole 22i or spin groove 22a.
[0029] The top cover 23 is provided so as to be able to open and close freely relative to the inner cover 22, and can open and close the discharge hole 22b. In this embodiment, the top cover 23 is connected to the inner cover 22 by a second hinge 28 so as to be able to open and close freely.
[0030] More specifically, as shown in Figures 1 and 2, the top cover 23 has a top cover main body 23a formed in a plate shape, and a pair of second hinges 28 are integrally provided on one end of the top cover main body 23a. The pair of second hinges 28 are each rotatably supported by the nozzle cap 22j of the inner cover 22. The top cover 23 rotates relative to the inner cover 22 about the second hinges 28, so that the top cover 23 can be opened and closed between a closed state relative to the inner cover 22 as shown in Figures 1 and 2 and an open state relative to the inner cover 22 as shown in Figures 4 and 5.
[0031] The top cover 23, the second hinge 28, and the nozzle cap 22j may be integrally formed by injection molding of a synthetic resin material. In this case, the second hinge 28 may be formed in the shape of a folded thin plate, similar to the first hinge 24.
[0032] A cylindrical closure plug 23b is integrally provided on the underside of top lid main body 23a, with its center at axis O. When top lid 23 is closed, the lower end of closure plug 23b abuts against the entire periphery of discharge hole 22b of nozzle cap 22j, thereby closing discharge hole 22b with top lid 23. On the other hand, when top lid 23 is opened, closure plug 23b moves away from nozzle cap 22j, opening discharge hole 22b.
[0033] The top lid 23 may be configured such that an operation piece 23c used for opening and closing the top lid 23 is provided integrally with the top lid main body 23a. The top lid 23 may also be configured with a pair of locking protrusions 23d that are provided integrally on both sides of the operation piece 23c and that engage with locking holes 22v provided in the nozzle cap 22j when the top lid 23 is closed to hold the top lid 23 in the closed state.
[0034] The discharge container 1 according to this embodiment having the above-described configuration can discharge the content liquid 2 contained in the container body 10 in three modes: large amount discharge, mist discharge, and small amount discharge.
[0035] In either case, when discharging the content liquid 2, the inner lid 22 is opened relative to the cap body 21 in advance, and the pull ring 21h is pulled to remove the stopper body 21f from the cap body 21, thereby opening the discharge port 21a.
[0036] To discharge the content liquid 2 in a large amount, the inner lid 22 is opened relative to the cap body 21, as shown in Fig. 3. When the inner lid 22 is opened relative to the cap body 21, the discharge port 21a is exposed to the outside, and by tilting the discharge container 1 in this state, the content liquid 2 contained in the container body 10 can be discharged in large amounts to the outside from the discharge port 21a.
[0037] To discharge the content liquid 2 in a mist-discharge mode, as shown in FIG. 4, the inner lid 22 is closed to the cap body 21 and the top lid 23 is opened relative to the inner lid 22. When the top lid 23 is opened relative to the inner lid 22, the discharge hole 22b is exposed to the outside. In this state, by tilting the discharge container 1 and strongly squeezing the barrel 12 of the container body 10, the content liquid 2 inside the container body 10 is discharged from the discharge port 21a toward the discharge tool 20, opening the slit valve 25. The content liquid 2 is then pumped through the communication hole 22i, the inlet groove 22m, the outlet groove 22n, the annular groove 22r, the spin groove 22a, and the outlet chamber 22q to the discharge hole 22b, where it can be discharged to the outside from the discharge hole 22b. At this time, by strongly squeezing the barrel 12 of the container body 10, the speed of the content liquid 2 passing through the spin groove 22a can be made relatively fast, and the content liquid 2 passing through the spin groove 22a can be discharged in a mist-like manner from the discharge hole 22b.
[0038] In contrast, to discharge the content liquid 2 in a small amount, the inner lid 22 is closed relative to the cap body 21 and the top lid 23 is opened relative to the inner lid 22, and in this state, the body 12 of the container body 10 is squeezed less strongly than when discharging mist while tilting the discharge container 1, as shown in Fig. 5. By squeezing the body 12 of the container body 10 relatively weakly in this way, the speed of the content liquid 2 passing through the spin groove 22a can be relatively slowed, and the content liquid 2 that has passed through the spin groove 22a can be discharged in small amounts linearly from the discharge hole 22b.
[0039] Thus, with the discharge container 1 according to this embodiment, the content liquid 2 contained in the container body 10 can be discharged in three modes: large amount discharge, mist discharge, and small amount discharge, by simply switching the opening and closing of the middle lid 22 or the top lid 23.
[0040] Furthermore, in the discharge container 1 according to this embodiment, the inner lid 22 is connected to the cap body 21 by the first hinge 24 so as to be freely opened and closed, and the top lid 23 is connected to the inner lid 22 by the second hinge 28 so as to be freely opened and closed. This makes it easy to open and close the inner lid 22 relative to the cap body 21 and the top lid 23 relative to the inner lid 22, and makes it easier to discharge the content liquid 2 contained in the container body 10 in three modes: large amount discharge, mist discharge, and small amount discharge.
[0041] Furthermore, in the discharge container 1 according to this embodiment, a slit valve 25 is provided between the discharge outlet 21a and the spin groove 22a, so that when the discharge container 1 is not in use, i.e., when the inner lid 22 is closed to the cap body 21 and the top lid 23 is closed to the inner lid 22, if the discharge container 1 is suddenly tilted, the content liquid 2 contained in the container body 10 is prevented from flowing to the discharge hole 22b, thereby preventing dripping of liquid from the discharge hole 22b.
[0042] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.
[0043] For example, in the above embodiment, the inner lid 22 is connected to the cap body 21 by the first hinge 24 so as to be able to open and close freely, but this is not limited thereto, and the inner lid 22 may be removably fitted and fixed to the cap body 21, and may be opened by being removed from the cap body 21 together with the top lid 23, thereby exposing the discharge port 21a. Similarly, in the above embodiment, the top lid 23 is connected to the inner lid 22 by the second hinge 28 so as to be able to open and close freely, but this is not limited thereto, and the top lid 23 may be removably fitted and fixed to the inner lid 22, and may be opened by being removed from the inner lid 22, thereby exposing the discharge port 22b.
[0044] Furthermore, the discharge container 1 may be configured without the plug 21f and the slit valve 25.
[0045] Furthermore, the discharge container 1 may be configured such that a plurality of discharge holes 22b are provided in the inner lid 22, so that the content liquid 2 is discharged in a shower-like manner from the plurality of discharge holes 22b. [Explanation of symbols]
