DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0019] As shown in Figs. 1 to 9, in the first embodiment of the present invention, a refillable container 1 has a container body 3 having a storage space S for storing contents 2, a movable part 4 having a nozzle 4a and held by the container body 3 so as to be movable between an open position (position shown in Fig. 1) and a closed position (position shown in Fig. 2) which is located closer to the axial tip of the nozzle 4a than the open position, and an opening / closing part 5 formed between the container body 3 and the movable part 4, the tip of the nozzle 4a having a discharge port 6a and an air replacement port 7a, the air replacement port 7a introducing air toward the storage space S as the contents 2 are discharged (see Fig. 4), the opening / closing part 5 opening a flow path of the contents 2 from the storage space S toward the discharge port 6a by the movement of the movable part 4 from the closed position to the open position (see Fig. 4), and closing the flow path of the contents 2 from the storage space S toward the discharge port 6a by the movement of the movable part 4 from the open position to the closed position (see Fig. 6).
[0020] According to the above configuration, as shown in FIG. 3, the movable part 4 is moved from the open position to the closed position, and the nozzle 4a is inserted into the mouth part 8a of the main container 8 while the opening and closing part 5 is closing the flow path of the contents 2 from the storage space S toward the discharge port 6a. As shown in FIG. 4, the movable part 4 is moved from the closed position to the open position, and the flow path of the contents 2 from the storage space S toward the discharge port 6a is opened by the opening and closing part 5, so that the contents 2 stored in the storage space S of the refillable container 1 can be discharged from the discharge port 6a and transferred into the main container 8. Therefore, it is possible to prevent the contents 2 from spilling when the nozzle 4a is inserted into the mouth part 8a of the main container 8. Also, as shown in FIG. 5, when the upper surface of the contents 2 in the main container 8 reaches the air replacement port 7a of the nozzle 4a, the air replacing the contents 2 discharged from the storage space S cannot be sucked from the air replacement port 7a, and the discharge of the contents 2 from the discharge port 6a automatically stops, so that it is possible to prevent the contents 2 from overflowing from the main container 8. Thereafter, as shown in Fig. 6, the movable part 4 is moved from the open position to the closed position to close the flow path of the contents 2 from the storage space S toward the discharge port 6a by the opening / closing part 5, and in this state, the nozzle 4a can be removed from the mouth part 8a of the container 8 as shown in Fig. 7. Therefore, spillage of the contents 2 can be prevented even when the nozzle 4a is removed from the mouth part 8a of the container 8. The contents 2 are not particularly limited and may be, for example, a fluid such as a liquid or a powder.
[0021] The movable part 4 has a discharge flow path 6 having a discharge port 6a, and the opening / closing part 5 opens the inlet 6b of the discharge flow path 6 by moving the movable part 4 from the closed position to the open position, and closes the inlet 6b of the discharge flow path 6 by moving the movable part 4 from the open position to the closed position. According to the above configuration, the opening / closing part 5 can be realized with a simple structure.
[0022] The movable part 4 has a discharge flow path 6 having a discharge port 6a and an air replacement flow path 7 having an air replacement port 7a, the discharge flow path 6 is annular and surrounds the air replacement flow path 7, and the air replacement port 7a is located closer to the axial tip side than the discharge port 6a. According to the above configuration, the movable part 4 can be realized with a simple structure.
[0023] The refillable container 1 has a lid 9 that can be detached from the container body 3 by moving the movable part 4 from the open position to the closed position. According to the above configuration, the movable part 4 can be automatically moved from the open position to the closed position by the operation of detaching the lid 9 from the container body 3, which makes it possible to facilitate the refilling operation.
[0024] As in the second embodiment shown in Figures 10 to 18, the refillable container 1 may be configured to have a biasing part 10 that biases the movable part 4 in a direction moving it from the open position to the closed position. According to the above configuration, the movable part 4 can be moved from the closed position to the open position by applying an external force that resists the biasing force from the biasing part 10, and the movable part 4 can be automatically moved from the open position to the closed position by the biasing force from the biasing part 10 when the external force is removed, making it even more difficult for the contents 2 to spill during refilling.
[0025] In the second embodiment, the refillable container 1 has a rotating part 11 that is guided by the container body 3 from an initial position (position shown in FIG. 12) to a tip side position (position shown in FIG. 13) that is located axially toward the tip side from the initial position by a one-side rotation operation that rotates toward one side in the circumferential direction of the nozzle 4a relative to the container body 3, a first end 10a that is connected to the movable part 4, and a second end 10b that is located axially toward the base end side of the nozzle 4a from the first end 10a. When the rotating part 11 is in the tip side position, the movable part 4 is The cover 9 includes a spring biasing portion 10 biasing the cover 9 in a direction from the open position to the closed position, and a cover 9 which rotates with the rotating portion 11 toward one circumferential side relative to the container body 3, thereby moving the rotating portion 11 from an initial position to a tip position, and is detached from the container body 3 (see Figs. 11 and 13), and rotates with the rotating portion 11 toward the other circumferential side of the nozzle 4a relative to the container body 3, thereby moving the rotating portion 11 from the tip position to the initial position, and is attached to the container body 3 (see Figs. 10 and 12). According to the above configuration, the biasing portion 10 is prevented from being compressed in the axial direction of the nozzle 4a when the cover 9 is attached to the container body 3, and therefore the elastic force of the biasing portion 10, which is a spring, is prevented from decreasing due to plastic deformation over time. The material of the spring portion is not particularly limited, but the above effect is particularly remarkable when the spring portion is made of resin.
[0026] The container body 3 has a guide portion 12 (see Figs. 12 and 13) that guides the guided portion 13 of the rotating portion 11 by one-side rotational motion, and one of the guide portion 12 and the guided portion 13 (the guide portion 12 in the second embodiment) may have an inclined surface 14 that inclines toward the axial tip side toward one circumferential side, a stopper 15 that stops the one-side rotational motion by contacting the other of the guide portion 12 and the guided portion 13 that has passed the end point of the inclined surface 14 by the one-side rotational motion, and a receiving surface 16 that receives the other of the guide portion 12 and the guided portion 13 between the inclined surface 14 and the stopper 15 so as to hold the rotating portion 11 at the tip side position. With the above-mentioned configuration, guiding of the rotating portion 11 can be realized with a simple structure.
[0027] It is preferable to provide multiple pairs of guiding portion 12 and guided portion 13 lined up in the circumferential direction as in the example shown in the figure, but the number of pairs of guiding portion 12 and guided portion 13 is not particularly limited, and a configuration in which only one pair is provided may be used.
[0028] In the first and second embodiments, the container set 17 has a refillable container 1 and a main container 8 having a mouth 8a into which the nozzle 4a of the refillable container 1 can be inserted, and the movable part 4 has an abutment part 4b that abuts against the mouth 8a when the nozzle 4a is inserted into the mouth 8a of the main container 8. According to the above configuration, the movable part 4 can be automatically moved from the closed position to the open position by inserting the nozzle 4a into the mouth 8a of the main container 8 and abutting the abutment part 4b against the mouth 8a, thereby facilitating the refilling operation.
[0029] In the first embodiment, the mouth 8a of the container 8 has a mouth fitting portion 8b that can be fitted to the movable part 4 of the refillable container 1 by abutting the abutting portion 4b of the movable part 4 against the mouth 8a, and the mouth fitting portion 8b has a fitting force that can maintain the fitting to the movable part 4 until the movable part 4 is moved from the open position to the closed position with respect to the container body 3 (see Figs. 6 and 8). In other words, the force required to release the fitting with the mouth fitting portion 8b and pull the movable part 4 up from the mouth fitting portion 8b (in the example shown in Fig. 8, the force for the protrusion 4c on the movable part 4 side to overcome the protrusion 8c on the mouth 8a side) is larger than the force required to move the opening / closing part 5 from the open position to the closed position (in the example shown in Fig. 9, the force for the protrusion 3a on the container body 3 side to overcome the opening / closing part 5). According to the above configuration, the abutting portion 4b of the movable part 4 is abutted against the mouth 8a to engage the movable part 4 with the mouth fitting portion 8b, and the contents 2 are transferred into the main container 8, and then the opening / closing part 5 is moved from the open position to the closed position by a simple operation of lifting the container body 3 of the refillable container 1 from the main container 8, and then the engagement of the movable part 4 with the mouth fitting portion 8b is released, and the nozzle 4a can be removed from the mouth 8a. Note that in the second embodiment, since the biasing portion 10 is used, it is not necessary to use the above configuration, but the above configuration may be used in combination.
[0030] In the first and second embodiments, the container body 3 is composed of a bottle-shaped container body 18 having a mouth 18a, and a mouth extension member 19 attached to the mouth 18a, and the movable part 4 is composed of a nozzle tip member 20 having an inner tube 20a forming a discharge port 6a, an outer tube 20b located radially outside the inner tube 20a and radially inside the axial tip of the mouth extension member 19 and forming the discharge port 6a between the inner tube 20a, and a nozzle outer periphery 20c located radially outside the axial tip of the mouth extension member 19, and a nozzle tip member 20 having a nozzle outer periphery 20c located radially outside the axial tip of the mouth extension member 19 in the open position. 9 and in the closed position, an inlet 6b of a discharge flow path 6 located axially further toward the tip side than the contact surface 21a, a fitting portion 21b located axially further toward the tip side than the inlet 6b and fitting with an outer cylinder 20b of a nozzle tip member 20, and a pipe holding portion 21c located axially further toward the base end than the contact surface 21a, and a pipe 22 held by the pipe holding portion 21c of the nozzle base member 21 and forming an air replacement flow path 7 in cooperation with the inner cylinder 20a of the nozzle tip member 20. With the above configuration, a refillable container 1 can be realized with a simple structure.
[0031] In the second embodiment, the nozzle tip member 20 has a biasing portion 10 which is a spring portion having a first end 10a connected to the nozzle outer circumferential portion 20c, and a rotating portion 11 connected to a second end 10b of the biasing portion 10, and the mouth extension member 19 has a guide portion 12. According to the above configuration, a refillable container 1 having the biasing portion 10 with a simple structure can be realized.
[0032] The refillable containers 1 of the first and second embodiments may be configured such that, instead of providing a pipe 22 and providing a pipe holder 21c on the nozzle base member 21 as in the third embodiment shown in Fig. 19, the nozzle base member 21 has a tubular body 21d extending from the contact surface 21a to the base end side in the axial direction, and the air replacement flow path 7 is formed by the tubular body 21d and the inner tube 20a of the nozzle tip member 20. With this configuration, the structure can be further simplified.
[0033] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and the above-described embodiment can be modified in various ways without departing from the gist of the present invention.
