DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] As shown in FIGS. 1 to 4, in one embodiment of the present invention, a metered dispensing container 1 includes a container body 2 having a mouth 2a, a body, and a bottom, connected in this order, to form a storage space S for storing a liquid content 4, and a metered dispenser 3 attached to the mouth 2a. The container body 2 is a bottle-shaped blow-molded container made of resin, with the body having elasticity that allows for squeezing, and the bottom surface of the bottom having a grounding portion. The liquid content 4 is not particularly limited as long as it is a liquid, and may be, for example, a disinfectant such as a mouthwash or gargle. In this embodiment, the up-down direction refers to the vertical direction when the bottom of the container body 2 is placed upright, and coincides with the direction along the central axis O passing through the center of the mouth 2a. In this embodiment, the direction perpendicular to the central axis O is referred to as the radial direction, and the direction circumferential around the central axis O is referred to as the circumferential direction.

[0016] The metering dispenser 3 has a metering chamber C formed by a peripheral wall portion 3a extending in the circumferential direction, a bottom wall portion 3b connected to the peripheral wall portion 3a, and a measuring cylinder 3c extending in the vertical direction, and a dispensing flow path R formed by a dispensing flow path forming portion 3d, extending from an inlet R1 provided at the bottom of the metering chamber C to a dispensing outlet R4 provided outside the metering chamber C. In response to a squeezing operation on the barrel of the container body 2, the metering chamber C introduces and stores the content liquid 4 within the container body 2 through the metering cylinder 3c up to a predetermined liquid level L (see FIG. 2), and returns the content liquid 4 introduced above the liquid level L through the metering cylinder 3c into the container body 2. The dispensing flow path R introduces the content liquid 4 stored up to the liquid level L from the inlet R1, passes through the uppermost portion R2 (at the time of dispensing) of the dispensing flow path R which is lower than the liquid level L, and dispenses it from a dispensing outlet R4 located below the bottom of the metering chamber C (see FIG. 3).

[0017] In this embodiment, the inlet R1 is provided below the lowest part C1 of the measuring chamber C. Therefore, the amount of content liquid 4 remaining in the measuring chamber C after measurement and dispensing can be reduced compared to when the inlet R1 is provided above the lowest part C1 of the measuring chamber C.

[0018] The metering dispenser 3 has an attachment tube 3e that is attached to the outer circumferential surface of the mouth 2a via a fitting 5 with the bottom wall 3b of the measuring chamber C in contact with the upper end surface of the mouth 2a. In this embodiment, the fitting 5 is composed of a male screw provided on the mouth 2a and a female screw provided on the attachment tube 3e, but is not limited thereto.

[0019] The measuring tube 3c has a cylindrical body 3c1 extending upward from the bottom wall portion 3b and a topped portion 3c2 connected to the upper end of the cylindrical body 3c1, and the topped portion 3c2 has a communication port 3c3 consisting of a pair of holes located at the same height and facing each other, which is formed by the upper end of the cylindrical body 3c1 and the topped portion 3c2, and the communication port 3c3 determines the liquid level L by allowing the content liquid 4 to flow in and out of the measuring chamber C.

[0020] The measuring dispenser 3 has a communication tube 3f extending downward from the bottom wall portion 3b, and the communication tube 3f connects the storage space S of the container body 2 with the internal space of the measuring tube 3c. The measuring tube 3c and the communication tube 3f are provided on the central axis O, but are not limited to this.

[0021] The pouring flow path forming portion 3d has a folded portion 3d1 that bends so as to convex upward and forms the uppermost portion R2 of the pouring flow path R, and the folded portion 3d1 forms a through-hole R3 in the peripheral wall portion 3a. The pouring flow path forming portion 3d has an inner pipe portion 3d2 that extends upward from the inlet R1 to the through-hole R3 radially inward of the peripheral wall portion 3a and is connected to the peripheral wall portion 3a to form a tubular shape, and a nozzle portion 3d3 that extends from the through-hole R3 to the pouring outlet R4.

[0022] The metered dispensing container 1 has an opening / closing cap 6 attached to the peripheral wall 3a so as to be movable between a sealed position and an unsealed position, and an outside air introduction path P formed between the peripheral wall 3a and the opening / closing cap 6. The opening / closing cap 6 has a seal portion 6a that seals the communication port 3c3 of the measuring tube 3c in the sealed position (see FIG. 1) and opens the communication port 3c3 in the unsealed position (see FIG. 2). The outside air introduction path P introduces outside air into the measuring chamber C when the content liquid 4 stored up to the liquid level L is dispensed from the dispensing outlet R4 (see the thick arrow in FIG. 3). The outside air introduction path P can be provided, for example, by forming a groove in either or both of the peripheral wall 3a and the opening / closing cap 6.

[0023] The opening / closing cap 6 has a top wall portion 6b, a cylindrical portion 6c extending downward from the top wall portion 6b, and a sealing cylinder 6a1 extending downward from the top wall portion 6b radially inward of the cylindrical portion 6c. The cylindrical portion 6c is attached to the peripheral wall portion 3a so as to be movable between a sealed position and a non-sealed position. The sealing portion 6a is composed of the sealing cylinder 6a1 and a portion of the top wall portion 6b radially inward of the sealing cylinder 6a1. The non-sealed position is located above the sealed position. The upper end surface of the peripheral wall portion 3a abuts against the top wall portion 6b of the opening / closing cap 6 at the sealed position (see FIG. 1). When the cylindrical portion 6c moves from the sealed position to the non-sealed position (see the outline arrow in FIG. 2), it abuts against the retaining portion 3a1 of the peripheral wall portion 3a so as to restrict its upward movement (see FIG. 2). The sealing cylinder 6a1 is in close contact with the upper end of the outer circumferential surface of the cylinder 3c1 in the sealing position (see FIG. 1), and is spaced apart from the cylinder 3c1 in the non-sealing position (see FIG. 2).

[0024] The measuring dispensing container 1 has an attachment member 7 attached to the mouth portion 2a, a pipe 8 attached to the attachment member 7, a measuring chamber member 9 attached to the attachment member 7, a nozzle member 10 attached to the measuring chamber member 9, an opening / closing cap 6 attached to the measuring chamber member 9, and a nozzle cover 11 that is removed from the tip (lower end) of the nozzle member 10 when in use.

[0025] The mounting member 7 has a mounting tubular portion 3e, a lower bottom wall 3b1 extending radially inward from the upper end of the mounting tubular portion 3e, and a fitting tube 3f1 extending downward from around the through hole in the lower bottom wall 3b1, and the pipe 8 is held by fitting into the fitting tube 3f1 and extends downward from the fitting tube 3f1, and the communicating tube 3f is composed of the fitting tube 3f1 and the pipe 8.

[0026] The measuring chamber member 9 has an upper bottom wall 3b2, a peripheral wall portion 3a extending upward from the outer peripheral edge of the upper bottom wall 3b2, a measuring tube 3c extending upward from around the periphery of the through-hole in the upper bottom wall 3b2, and an inner tube portion 3d2 continuing to the upper bottom wall 3b2 and the peripheral wall portion 3a. The bottom wall portion 3b is formed by the upper bottom wall 3b2 and a lower bottom wall 3b1 of the mounting member 7. The bottom wall portion 3b also has a connecting portion 3b3 that tightly connects the base end of the measuring tube 3c to the base end of the communicating tube 3f.

[0027] The mounting member 7 has a fitting peripheral wall portion 3g extending upward from the lower bottom wall 3b1, and the measuring chamber member 9 is fitted into the fitting peripheral wall portion 3g to be mounted on the mounting member 7. The fitting peripheral wall portion 3g is provided on the outer peripheral edge portion of the lower bottom wall 3b1, and the measuring chamber member 9 fits into the fitting peripheral wall portion 3g at the lower end portion of the outer peripheral surface of the peripheral wall portion 3a, but is not limited to this.

[0028] The nozzle member 10 has a nozzle portion 3d3, and is attached to the measuring chamber member 9 by fitting into the peripheral wall portion 3a at the through hole R3.

[0029] The mounting member 7, the pipe 8, the measuring chamber member 9, the nozzle member 10, the open / close cap 6, and the nozzle cover 11 are each made of, for example, resin.

[0030] When using the metered dispensing container 1 of this embodiment, first, the opening / closing cap 6 is moved from the sealed position to the unsealed position, and the container body 2 is squeezed to introduce and store the content liquid 4 in the measuring chamber C up to the liquid level L (see FIG. 2). Once the content liquid 4 has been stored in the measuring chamber C up to the liquid level L, the top R2 of the dispensing flow path R is lower than the liquid level, and dispensing of the content liquid 4 through the dispensing flow path R begins according to the siphon principle. Furthermore, because the dispensing outlet R4 is located below the bottom of the measuring chamber C where the inlet R1 is located, once dispensing begins, the content liquid 4 stored in the measuring chamber C is dispensed while introducing outside air into the measuring chamber C, and the liquid level reaches the bottom of the measuring chamber C (see FIG. 3). Therefore, a fixed amount of the content liquid 4 measured and stored in the measuring chamber C can be dispensed. In addition, since the container body 2 can be simply squeezed without inverting the metered dispensing container 1, the measured content liquid 4 can be easily used. Furthermore, in this embodiment, since the measuring tube 3c is used for measuring, the number of parts can be reduced compared to conventional configurations in which the content is measured using a pump, thereby reducing costs.

[0031] Furthermore, the measuring and dispensing container 1 may be provided with a regulating structure that regulates the amount of pressure applied during the squeezing operation, so that excessive squeezing operation that introduces further content liquid 4 into the measuring chamber C after the content liquid 4 has been stored up to the liquid level L and dispensing of the content liquid 4 has begun is not possible. The regulating structure is not particularly limited, and any known structure can be employed.

[0032] As in the second embodiment shown in Figures 5 to 7, the outside air introduction path P may be configured to be closed in the non-sealed position (see Figure 7) and open in the sealed position (see Figure 6). According to this configuration, when in use, if the opening / closing cap 6 is placed in the non-sealed position, the liquid content 4 is introduced into the measuring chamber C and stored up to the liquid level L, and then the opening / closing cap 6 is not returned to the sealed position again, the introduction of outside air through the outside air introduction path P is prevented, and the liquid content 4 is prevented from being dispensed. Therefore, since the opening / closing cap 6 is always returned to the sealed position to dispense the liquid content 4, it is possible to prevent forgetting to close the opening / closing cap 6.

[0033] In the second embodiment, the opening / closing cap 6 has a peripheral sealing wall 6d extending downward from the top wall portion 6b so as to radially face the cylindrical portion 6c, and the peripheral sealing wall 6d contacts the peripheral wall portion 3a in the non-sealed position to block the outside air introduction path P, while in the sealed position it moves away from the peripheral wall portion 3a to open the outside air introduction path P. Note that in the second embodiment, the peripheral sealing wall 6d is provided radially inward from the cylindrical portion 6c, but this is not limiting, and the peripheral sealing wall 6d may be provided radially outward from the cylindrical portion 6c.

[0034] As in the third embodiment shown in Figure 8, the pouring flow path forming unit 3d has a movable part 10 that forms the pouring flow path R, including the pouring outlet R4, downstream of the uppermost part R2 of the pouring flow path R during pouring, and the movable part 10 may be configured to pour out the content liquid 4 by changing, in response to operation, from a non-pouring position in which the pouring outlet R4 is held above the liquid level L to a pouring position in which the pouring outlet R4 is held below the inlet R1. This configuration can prevent the content liquid 4 from starting to be poured in the middle of metering (i.e., before the content liquid 4 reaches the liquid level L). In the third embodiment, the nozzle member 10 is rotatably attached to the measuring chamber member 9 and constitutes the movable part 10.

[0035] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the above-described embodiments can be modified in various ways without departing from the gist of the present invention.
