Abstract
Description
[Technical field]
[0001] The present invention relates to a container with a dropper, and more particularly to a container with a dropper in which the liquid contained in the container is sucked into the dropper when the cap of the container is opened. [Background technology]
[0002] Conventionally, containers with droppers have been known as containers for storing liquid contents such as medicinal liquids and cosmetics, and have a container body with a nozzle, a cap part that is removably attached to the nozzle, and a dropper attached to the cap part (see, for example, Patent Document 1). In the container with a dropper described in Patent Document 1, the dropper is equipped with a pressure-deformable portion supported by the cap portion and capable of elastically deforming, and a tubular nozzle portion supported by the pressure-deformable portion; after the cap portion is removed from the mouth portion, the nozzle portion is inserted from the mouth portion into the inside of the container body, and the pressure-deformable portion is pressed and then restored to its original shape, thereby drawing up the liquid contents into the nozzle portion, and the pressure-deformable portion is pressed again to eject the liquid contents drawn up into the nozzle portion to the outside, which resulted in poor operability.
[0003] In response to this, there is also known a container with a dropper that can suck up a certain amount of liquid contents depending on the distance the cap rises when the cap is unscrewed from the mouth of the container body, and then eject the liquid by pressing a push button after removing the cap (see, for example, Patent Document 2).

[0004] [Patent Document 1] JP 2022-184186 A [Patent Document 2] JP 2016-33056 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, while the dropper-equipped container described in Patent Document 2 has good operability, there is a problem in that the dropper-equipped container is made up of a large number of parts, which increases the cost.
[0006] The present invention has an object to solve the above problems and to provide a container with a dropper that is low-cost and easy to operate by using simple parts. [Means for solving the problem]
[0007] In order to solve the above-mentioned problems, the present invention provides a container with a dropper, comprising a container body for storing the liquid contents, and a dropper member for sucking up the liquid contents from the container body, wherein the dropper member comprises a cap portion that is screwed onto the mouth of the container body so as to be able to be opened and closed freely, a dropper stopper body that is attached so as to be able to move up and down within the cap portion, closing the opening of the mouth portion and sucking up the liquid contents within the container body, and a pressure-deforming portion that is connected to the top of the dropper body and is deformed by pressure in order to suck up and discharge the liquid contents, wherein the pressure-deforming portion comprises a vertical bellows portion that expands and contracts when the cap portion is opened and closed, and a horizontal bellows portion that appears and retracts from the side of the cap portion when discharging.
[0008] In one embodiment of a container with a dropper, the dropper plug has a closing wall that closes the nozzle portion of the container body and a nozzle portion extending downward from the closing wall, and the pressure-deforming portion is connected to the closing wall of the dropper plug. The cap portion has a pressing member that presses the horizontal bellows portion. The cap portion has an upper cap portion that abuts against the vertical bellows portion and a lower cap portion that mounts the dropper plug so that it can move up and down. The dropper plug is formed integrally with the pressure-deforming portion. Effect of the Invention
[0009] By adopting the above-described configuration, the dropper-equipped container of the present invention can be used by rotating the cap portion to open it, whereby a predetermined amount of the liquid contents in the container body can be sucked up and stored in the dropper stopper body in the cap portion. Furthermore, the dropper-equipped container of the present invention can eject the liquid content by pressing the push button that protrudes from the side of the cap, and can be used by operating the dropper member with one hand.

[0011] Next, the dropper-equipped container of the present invention will be described with reference to the drawings showing an embodiment. In the following description, the up-down direction in FIG. 1 is referred to as the "axial direction", the up direction is referred to as the "upper", and the down direction is referred to as the "lower".
[0012] Example 1 In Figure 1, A is a container body that contains the liquid contents, B is a cap part that is attached to the mouth part 1 of container body A, C is a dropper stopper that is inserted into cap part B so as to be able to move up and down, closing the opening of mouth part 1 and sucking up the liquid contents in container body A, and D is a pressure-deformable part that is attached into cap part B and has dropper stopper part C attached below it, and cap part B, dropper stopper part C, and pressure-deformable part D constitute dropper member S. The pressure-deformed portion D is formed by direct blow molding so that a part of it becomes a thin-walled bellows, and is formed so as to be elastically deformable at least at a predetermined portion.
[0013] As shown in Figs. 1 and 3, the container body A comprises a nozzle portion 1 and a bottomed body portion 2, and a first male screw portion 3 is provided on the outer periphery of the nozzle portion 1.
[0014] As shown in Figures 1 to 3, cap part B comprises a top wall 5, a side wall 6 extending vertically from the outer edge of top wall 5, and a mounting wall 7 extending radially outward from the lower end of side wall 6. A horizontal hole 8 is drilled in a predetermined position of side wall 6 and is formed in a generally track-shaped ellipse which is longer vertically than horizontally. A pressing member 9 is inserted into horizontal hole 8, penetrating side wall 6 and movable back and forth relative to the axis.
[0015] A mounting cylinder 10 for mounting the upper end of the press-deformed portion D is vertically provided on the underside of the top wall 5 . A pair of guide ribs 11 are provided on the inner periphery of the side wall 6, opposite the lateral hole 8, to project in the axial direction in order to guide the dropper plug C in the axial direction. The inner circumference of the mounting peripheral wall 7 has at its upper part a sliding surface portion 7a along which the outer edge of the dropper stopper body C moves up and down, and at the lower end of the sliding surface portion 7a a locking protrusion 12 is provided which the outer edge of the dropper stopper body C rides over and which prevents the dropout, and below the locking protrusion 12 a first female thread portion 13 is provided which screws into the first male thread portion 3 on the outer circumference of the mouth portion 1 of the container body A.
[0016] The pressing member 9 includes a lateral peripheral wall 15 formed in a shape that slides back and forth inside the lateral hole 8, which is formed in a substantially track elliptical shape, a pressing wall 16 that closes the outer opening end of the lateral peripheral wall 15, and a flange 17 that protrudes from the inner end of the outer periphery of the lateral peripheral wall 15 to prevent the pressing member 9 from falling out of the lateral hole 8.
[0017] As shown in Figures 1 to 3, the dropper stopper C comprises a ring-shaped closure wall 20 with a gasket P attached to its underside, a nozzle portion 21 extending downward from the inner edge of the closure wall 20 and having a reduced diameter at its lower end for sucking up the liquid content, an attachment wall 22 erected from the upper surface of the closure wall 20 and for attaching a pressure-deformation portion D, and a tightly fitting inner tube 23 erected from the inner edge of the closure wall 20 and having its outer periphery in close contact with the inner periphery of the pressure-deformation portion D. The outer edge of the closing wall 20 is formed with a diameter that allows it to move up and down within the sliding surface portion 7 a of the mounting peripheral wall 7 of the cap portion B and to overcome the locking projection 12 .
[0018] The mounting wall 22 has a second female thread 25 screwed into its inner periphery, and a guide protrusion 26 that is guided in the axial direction by a guide rib 11 on the side peripheral wall 6 of the cap portion B protrudes from a predetermined position on its outer periphery.
[0019] As shown in Figures 1 to 3, the pressure-deformation portion D comprises a cylindrical main body portion 30 extending vertically, an attachment tube portion 31 formed at the lower portion of the main body portion 30, a vertical pressure-deformation portion 32 extending upward from the upper end of the main body portion 30 and attached with its upper surface abutting against the attachment tube 10 below the top wall 5 of the cap portion B when set, and which is capable of being crushed and deformed in the vertical direction, and a horizontal pressure-deformation portion 33 which has a horizontal opening 33a drilled at a predetermined position on the side circumference of the main body portion 30, extends horizontally from the horizontal opening 33a, has a tip portion abutting the inside of the pressing member 9, and is capable of being crushed and deformed in the front-to-rear direction. The mounting tube portion 31 is provided on its outer periphery with a second male screw portion 34 which screws into the second female screw portion 25 on the inner periphery of the mounting wall 22 of the dropper plug C.
[0020] The vertical pressure deformation portion 32 is connected to the upper end of the main body portion 30 and includes a thin-walled vertical bellows portion 35 which can be deformed by being crushed vertically, a vertical pressure wall portion 36 which closes the inner upper end of the vertical bellows portion 35, and a mounting protrusion 37 which protrudes from the center of the vertical pressure wall portion 36 and is mounted inside the mounting tube 10 of the cap portion B.
[0021] The lateral pressure deformation portion 33 is connected to a lateral opening 33a of the main body portion 30, and includes a thin-walled lateral bellows portion 38 which can be deformed by being crushed back and forth, and a push button portion 39 which closes the inner peripheral tip of the lateral bellows portion 38. In addition, before the pressing member 9 is pressed when setting, the outer periphery of the tip of the horizontal bellows portion 38 is inserted into the side peripheral wall 15 of the pressing member 9, and is guided on both sides to have a diameter that allows it to move up and down. The outer surface of the push button portion 39 is set so as to abut or be close to the inner surface of the pressing wall 16, and is formed so as to push back outward when the pressing member 9 is pressed inward.
[0022] Next, the manner of use and the effects of this embodiment will be described. First, the mounting tube portion 31 of the press-deformation portion D is set from above inside the mounting wall 22 of the dropper plug C, and the second female thread portion 25 and the second male thread portion 34 are screwed together to mount the press-deformation portion D to the dropper plug C. At this time, as shown in FIG. 2(b), guide protrusion 26 on the outer periphery of mounting wall 22 of dropper stopper body C and lateral pressure deformation portion 33 of pressure deformation portion D are set to face in opposite directions, and tightly fitting inner tube 23 of dropper stopper body C is inserted into and tightly fitted to the inner periphery of mounting tube portion 31 of pressure deformation portion D.
[0023] Next, the pressing member 9 is inserted from inside into the lateral hole 8 of the side peripheral wall 6 to attach the cap portion B, and the dropper plug body C and the pressing deformation portion D are inserted from below into the cap portion B and set. When the pressure-deformed portion D is inserted into the cap portion B, the tip of the lateral pressure-deformed portion 33 abuts against the lower end and inner surface of the mounting peripheral wall 7 of the cap portion B, but since the lateral pressure-deformed portion 33 itself is pushed inward and deformed, it does not interfere with the insertion. As the dropper stopper body C and the pressure-deformation portion D are inserted into the cap portion B, the tip of the lateral pressure-deformation portion 33 penetrates into the pressing member 9 and slides upward, while the guide protrusion 26 of the dropper stopper body C is inserted from below between a pair of guide ribs 11 on the inner circumference of the side wall 6 of the cap portion B, guiding the up and down movement of the dropper stopper body C and the pressure-deformation portion D within the cap portion B.
[0024] Finally, the mounting protrusion 37 of the vertical pressure deformation portion 32 of the pressure deformation portion D is fitted into the mounting tube 10 of the cap portion B and the outer periphery of the closure wall 20 of the dropper stopper body C climbs over the locking protrusion 12 of the mounting peripheral wall 7 of the cap portion B and is inserted into the inside of the sliding surface portion 7a, so that the dropper stopper body C and the pressure deformation portion D are mounted inside the cap portion B so as not to fall out, as shown in Figure 2.
[0025] Next, the cap portion B is placed on the nozzle portion 1 of the container body A filled with the liquid, and then screwed to close the container body. When closing the lid, the first male threaded portion 3 and the first female threaded portion 13 on the inner circumference of the mounting wall 7 of the cap portion B screw together, and as shown in Figure 3, the upper end of the mouth portion 1 of the container body A abuts against the gasket P on the underside of the closure wall 20 of the dropper stopper C in the cap portion B. As the screwing progresses further, the upper end of the mouth portion 1 pushes up the underside of the closure wall 20 of the dropper stopper C, and the tip of the lateral pressure deformation portion 33 of the pressure deformation portion D moves inside the pressing member 9. At the same time, the guide protrusion 26 of the dropper stopper C is guided by a pair of guide ribs 11 on the side wall 6 of the cap portion B, and the dropper stopper C rises inside the cap portion B. As the dropper plug body C rises, the pressure-deformed portion D is also lifted, and as it comes into contact with the underside of the top wall 5 of the cap portion B, the vertical bellows portion 35 of the vertical pressure-deformed portion 32 is crushed and deformed, and the volume inside the vertical pressure-deformed portion 32 decreases. As the vertical pressure-deformed portion 32 is crushed and reduced in volume, the air within the pressure-deformed portion D is pushed, passes through the nozzle portion 21 from the inner edge of the closure wall 20 of the attached dropper stopper body C, and is pushed out from the lower end of the nozzle portion 21 into the container body A.
[0026] Finally, as shown in FIG. 1, the upper outer surface of the closure wall 20 of the dropper plug body C abuts against the inner lower surface of the side wall 6 of the cap part B, completing the screwing, and crushing the vertical pressure-deformation part 32 of the pressure-deformation part D, thereby closing the cap in a reduced volume state. In addition, since the air within the nozzle portion 21 is pushed out into the container body A, the liquid content does not remain within the nozzle portion 21.
[0027] To use the container of this embodiment, first, the container is turned upright and the cap portion B is rotated relative to the container body A to open it. When the cap part B is rotated, the locking protrusion 12 on the mounting peripheral wall 7 rises to a position where it abuts against the underside of the outer edge of the closure wall 20, and the crushed vertical pressure-deformed part 32 is pushed back to its original shape by fitting with the underside of the top wall 5 of the cap part B. Furthermore, as the vertical pressure deformation portion 32 is returned to its original shape, it presses downward against the main body portion 30 of the pressure deformation portion D and the dropper stopper body C, pushing the dropper stopper body C downward within the cap portion B and pressing the lower surface of the closure wall 20 against the upper end surface of the nozzle portion 1 until the cap portion B has finished unscrewing and is opened.
[0028] As the vertical pressure deformation portion 32 is returned to its original shape, the volume within the vertical pressure deformation portion 32 is returned to its original shape, and the pressure within the pressure deformation portion D becomes negative by the amount of the reduction in volume, and the liquid contents are sucked up from the lower end of the nozzle portion 21 into the nozzle portion 21 of the attached dropper stopper body C.
[0029] The cap part B presses the lower surface of the closing wall 20 of the dropper stopper body C against the upper end surface of the nozzle part 1 while the cap is closed until it is unscrewed and opened, so that the inside of the container body A is stable and the content liquid is sucked up into the nozzle part 21 of the dropper stopper body C, so that a stable suction capacity can be maintained.
[0030] As shown in Figure 4, when the pressing member 9 attached to the side wall 6 of the cap part B is pressed inward toward the point from which the lower end of the nozzle part 21 is to be discharged, the pressing wall 16 of the pressing member 9 abuts against and presses against the push button part 39 of the lateral pressure deformation part 33 of the pressure deformation part D, crushing and deforming the lateral bellows part 38, reducing the volume of the lateral pressure deformation part 33, pushing out the air from within the pressure deformation part D through the lateral opening 33a, and the content liquid sucked up into the attached nozzle part 21 can be discharged from the lower end of the nozzle part 21 and used. After the content liquid has been discharged, the pressing member 9 is released, causing the laterally deformed portion 33 to return to its original state, and air is sucked inward from the lower end of the nozzle portion 21 by an amount equal to the reduction in volume, resulting in stability.
[0031] When the discharge of the liquid contents sucked up into the nozzle portion 21 has finished and a predetermined amount of liquid is to be used, the cap portion B is again screwed onto the mouth portion 1 of the container body A, and then the cap portion B is unscrewed, so that the pressure deformation portion D can suck up a predetermined amount of the liquid contents into the nozzle portion 21, and the pressure member 9 of the cap portion B can be pushed inward to discharge the liquid contents from inside the nozzle portion 21 to the outside, thereby allowing the predetermined amount to be used stably.
[0032] If it is desired to use the set cap part B as a dropper rather than a specified amount, after pressing the pressing member 9 on the side wall 6 of the cap part B, the lower end of the nozzle part 21 is immersed in the liquid contents inside the container body A, and when the pressing member 9 is released, the lateral pressing deformation part 33 returns to its original state, and the liquid contents are sucked in from the lower end of the nozzle part 21 by the amount of the reduced volume, and by pressing the pressing member 9 again, the liquid contents sucked into the nozzle part 21 can be expelled from the lower end of the nozzle part 21, so that the pressing member 9 can be repeatedly operated to use it as a normal dropper. In addition, after opening the cap part B with one hand, the content liquid can be discharged by pressing the pressing member 9 protruding from the side wall 6 of the cap part B, so that the operation can be performed without changing the grip with one hand.
[0033] In this embodiment, the vertical press-deformation portion 32 of the press-deformation portion D is made crushable and deformable in the up-down direction by a thin-walled vertical bellows portion 35 which can be crushed and deformed in the up-down direction, and a vertical pressing wall portion 36 which closes the upper inner circumferential end of the vertical bellows portion 35, and the horizontal press-deformation portion 33 is made crushable and deformable in the front-to-back direction by a thin-walled horizontal bellows portion 38 which can be crushed and deformed in the front-to-back direction, and a push button portion 39 which closes the inner circumferential end of the horizontal bellows portion 38. However, since it is sufficient if the pressing wall portion can be crushed in the up-down direction or the front-to-back direction to reduce its volume and restore to its original state, a crushable and restorable dome wall that protrudes outward may be used instead of a bellows mechanism, or the like.
[0034] Example 2 Next, a second embodiment in which the configurations of the cap portion B and the pressure-deformable portion D of the first embodiment are modified will be described with reference to FIGS. In the following, the same parts as in the first embodiment are given the same reference numerals, and the differences will be mainly explained.
[0035] In Figure 5, A is a container body that contains the liquid contents, E is a cap part that is attached to the mouth part 1 of the container body A, C is a dropper stopper that is inserted into the cap part E so as to be movable up and down, closing the opening of the mouth part 1 and sucking up the liquid contents in the container body A, Da is a pressure-deformable part that is attached into the cap part E and has the dropper stopper C attached below it, and the cap part E, the dropper stopper C, and the pressure-deformable part Da constitute the dropper member Sa. The pressure-deformed portion Da is formed by direct blow molding so that a part of it becomes a thin-walled bellows, and is formed to be elastically deformable at least at a predetermined portion.
[0036] As shown in Figures 5 and 6, the cap part E comprises an upper cap part E1 to which the pressure deformation part Da is attached, and a lower cap part E2 to which the upper cap part E1 is attached at the top and which is also attached to the mouth part 1 of the container body A.
[0037] The upper cap portion E1 comprises a top wall 45 and a side peripheral wall 46 vertically extending from the outer edge of the top wall 45. A horizontal hole 47 which is longer vertically than horizontally is cut out to the bottom end at a predetermined position of the side peripheral wall 46.
[0038] A mounting cylinder 48 for mounting the upper end of the press-deformed portion Da is vertically provided on the lower surface of the top wall 45 . A pair of engagement ribs 49 protrude from the inner periphery of the side wall 46 on the side opposite the horizontal hole 47, and an engagement protrusion 50 protrudes from the lower end of the inner periphery excluding the horizontal hole 47, for mounting the lower cap portion E2.
[0039] The lower cap portion E2 has a dropper plug C attached to its inner periphery so that it can move up and down, and is provided with a mounting peripheral wall 55 which is screwed into the mouth portion 1 of the container body A, and an engagement wall 56 which is erected on the inner periphery of the upper end of the mounting peripheral wall 55. The inner circumference of the mounting peripheral wall 55 has at its upper part a sliding surface portion 55a along which the outer edge of the dropper stopper body C moves up and down, and at the lower end of the sliding surface portion 55a a locking protrusion 57 is provided which the outer edge of the dropper stopper body C rides over and which prevents the dropout, and below the locking protrusion 57 a first female thread portion 58 is provided which screws into the first male thread portion 3 on the outer circumference of the mouth portion 1 of the container body A. A notch 59 is cut out from the upper end to the lower end of the engagement wall 56 at a position that is inside the horizontal hole 47 when set, and a pair of guide ribs 60 are protruded in the axial direction on the opposite side to the notch 59 to guide the dropper plug C in the axial direction, and an engagement portion 61 is provided on the outer periphery to engage with the engagement protrusion 50 of the upper cap portion E1.
[0040] As shown in Figures 5 and 6, the press-deformation portion Da comprises a cylindrical main body portion 30 extending vertically, an attachment tube portion 31 formed at the lower portion of the main body portion 30, a vertical press-deformation portion 32 extending upward from the upper end of the main body portion 30, whose upper surface is attached to the attachment tube 48 of the top wall 45 of the cap portion E when set, and which is capable of being crushed and deformed in the vertical direction, and a horizontal press-deformation portion 65 which has a horizontal opening 65a drilled at a predetermined position on the side circumference of the main body portion 30, extends horizontally from the horizontal opening 65a, and is formed so that its tip portion protrudes outward through the cut-out portion 59 and the horizontal hole 47 when set, and which is capable of being crushed and deformed in the front-rear direction. The vertically pressurized deformation portion 32 has a mounting protrusion 37 that is mounted in a mounting tube 48 of the upper cap portion E1.
[0041] The lateral pressure deformation portion 65 is connected to the lateral opening 65a of the main body portion 30, and is equipped with a thin-walled lateral bellows portion 66 which can be deformed by being crushed back and forth, and a push button portion 67 which closes the inner peripheral tip of the lateral bellows portion 66 and has a tip which penetrates the cutout portion 59 and the lateral hole 47 and projects out to the outside of the cap portion E when set.
[0042] Next, the manner of use and the effects of this embodiment will be described. First, the pressure-deforming portion Da is attached to the dropper plug C. Next, the dropper plug C and the pressure-deformable portion Da are inserted from below the lower cap portion E2 and set. When the pressure deformation portion Da is inserted into the lower cap portion E2, the push button portion 67 of the lateral pressure deformation portion 65 abuts against the lower end and inner surface of the mounting peripheral wall 55 of the lower cap portion E2, but since the lateral bellows portion 66 deforms, the lateral pressure deformation portion 65 is pushed inward and does not interfere with the insertion. As the dropper stopper body C and the pressure-deformation portion Da are inserted into the lower cap part E2, the push button portion 67 of the lateral pressure-deformation portion 65 penetrates the cutout portion 59 and the lateral hole 47 and slides upward, while the guide protrusion 26 of the dropper stopper body C is inserted from below between a pair of guide ribs 60 on the inner circumference of the engagement wall 56 of the lower cap part E2, and the up and down movement of the dropper stopper body C and the pressure-deformation portion Da is guided within the lower cap part E2.
[0043] Finally, the upper cap part E1 is attached from above the lower cap part E2, and the attachment protrusion 37 of the vertical pressure deformation part 32 of the pressure deformation part Da is inserted into the attachment tube 48 of the upper cap part E1 and set.
[0044] Next, the lower cap part E2 is placed on the nozzle part 1 of the container body A filled with the liquid, and the lower cap part E2 is screwed on and closed with the cap part E that has been set. When closing the lid, the vertical pressure deformation portion 32 is crushed and reduced in volume, pushing the air inside the pressure deformation portion Da, passing through the inner edge of the closure wall 20 of the attached dropper stopper body C into the nozzle portion 21 and being pushed out from the lower end of the nozzle portion 21 into the container body A. Finally, as shown in Figure 5, the upper surface of the outer edge of the closure wall 20 of the dropper stopper body C abuts against the inner side of the lower surface of the side wall 46 of the lower cap portion E2, completing the screwing, and the vertical pressure deformation portion 32 of the pressure deformation portion Da is crushed and the lid is closed in a reduced volume state.
[0045] In this embodiment, when the set cap portion E is rotated relative to the container body A, the locking protrusion 57 on the mounting peripheral wall 55 rises to a position where it abuts the underside of the outer edge of the closure wall 20, and the crushed vertical pressure-deformed portion 32 of the pressure-deformed portion Da returns to its original state, allowing air to flow in and out of the pressure-deformed portion Da, so that a predetermined amount of the liquid contents in the container body A can be sucked up into the nozzle portion 21 of the dropper stopper body C.
[0046] As shown in FIG. 7, the liquid content sucked up into nozzle portion 21 of dropper plug C penetrates side hole 47 in cap portion E, and by pressing inward with a finger or the like against push button portion 67 of side pressure deformation portion 65 of protruding pressure deformation portion Da, side bellows portion 66 is crushed and deformed, reducing the volume of side pressure deformation portion 65, and the air within pressure deformation portion Da is pushed through side opening 65a, allowing the liquid content within nozzle portion 21 to be expelled to the outside and used.
[0047] Example 3 Next, a third embodiment in which the configurations of the cap portion B and the dropper plug C of the first embodiment are modified will be described with reference to Figs. 8 to 10. In the following, the same parts as in the first embodiment are given the same reference numerals, and the differences will be mainly explained.
[0048] In Figure 8, A is a container body that contains the liquid content, F is a cap part that is attached to the mouth part 1 of the container body A, and G is a dropper stopper with a pressure-deformable part that is attached inside the cap part F so as to be able to move up and down, closing the opening of the mouth part 1 and sucking up the liquid content inside the container body A, and the cap part F and the dropper stopper part G with a pressure-deformable part constitute a dropper member Sb. The dropper plug G with pressure-deformable portion is formed by direct blow molding so that a portion of the dropper plug G has a thin bellows shape, and is elastically deformable at least at a predetermined portion.
[0049] As shown in Figures 8 and 9, the cap portion F comprises a top wall 70, a side peripheral wall 71 extending vertically from the outer edge of the top wall 70, and a mounting peripheral wall 72 extending radially outward from the lower end of the side peripheral wall 71. A horizontal hole 73 is drilled at a predetermined position of the side peripheral wall 71 and is formed in a generally track-shaped ellipse which is longer vertically than horizontally, and a horizontal wall 74 is provided protruding laterally from the horizontal hole 73. The mounting peripheral wall 72 has an inner periphery provided with a first female thread portion 75 which screws into the first male thread portion 3 on the outer periphery of the nozzle portion 1 of the container body A.
[0050] As shown in Figs. 8 and 9, the dropper stopper G with a pressure-deformable portion comprises a ring-shaped closing wall 80 with a packing P attached to its underside, a nozzle portion 81 that extends downward from the inner edge of the closing wall 80 and has a reduced diameter at its lower end for sucking up the liquid content, a cylindrical press-deformable main body portion 82 that stands upright from the outer edge of the closing wall 80 and has its outer periphery inserted into the side peripheral wall 71 of the cap portion F, and a nozzle portion 82 that extends upward from the upper end of the press-deformable main body portion 82 and has its upper surface inserted below the top wall 70 of the cap portion F when set. The press-deformation body 82 has a horizontal opening 84a drilled at a predetermined location on the side circumference of the press-deformation body 82 and extends laterally from the horizontal opening 84a, which penetrates the horizontal hole 73 and the inner circumference of the horizontal peripheral wall 74 when set, and is guided on both sides to have a diameter that allows it to slide in the vertical direction, and has a tip that protrudes outward and is formed as a single unit.The press-deformation body 82 is configured to be capable of being pressed and deformed in the front-to-back direction, and is provided with a vertical press-deformation portion 84 which abuts against or is close to a surface and can be crushed and deformed in the vertical direction.
[0051] The vertical press-deformation portion 83 is connected to the upper end of the press-deformation main body portion 82, and is equipped with a thin-walled vertical bellows portion 85 which can be deformed by being crushed vertically, and a vertical press wall portion 86 which closes the inner upper end of the vertical bellows portion 85 and has its upper surface abutting or coming into close proximity to the lower surface of the top wall 70 of the cap portion F when set.
[0052] The lateral pressure deformation portion 84 is connected to a lateral opening 84a of the pressure deformation main body portion 82, and is provided with a thin-walled lateral bellows portion 88 which can be deformed by being crushed back and forth, and a push button portion 89 which closes the inside of the tip of the lateral bellows portion 88 and has a tip which protrudes outward from the inner periphery of the lateral peripheral wall 74 when set.
[0053] Next, the manner of use and the effects of this embodiment will be described. First, the dropper plug G with the pressure-deformable portion is inserted into the cap portion F from below and set in place. When the dropper plug G with a pressure-deformation portion is inserted into the cap portion F, the tip of the lateral pressure-deformation portion 84 abuts against the lower end and inner surface of the mounting peripheral wall 72 of the cap portion F, but since the lateral pressure-deformation portion 84 itself is pushed inward and deformed, it does not interfere with the insertion. Furthermore, when the dropper stopper body G with the pressure-deformation portion is inserted into the cap portion F, the tip of the lateral pressure-deformation portion 84 penetrates into the lateral hole 73 in the side wall 71 of the cap portion F, the lateral pressure-deformation portion 84 restores its original shape, and the up and down movement of the dropper stopper body G with the pressure-deformation portion is guided within the lateral hole 73.
[0054] Finally, as shown in FIG. 9, the upper surface of the vertical pressing wall portion 86 of the vertical pressing deformation portion 83 of the dropper stopper body G with a pressing deformation portion abuts against the lower surface of the top wall 70 of the cap portion F, stopping insertion, and the lower surface of the horizontal pressing deformation portion 84 abuts against the lower end of the horizontal hole 73, setting the dropper stopper body G with a pressing deformation portion so that it does not come off from within the cap portion F.
[0055] Next, the cap part F is placed over the mouth part 1 of the container body A filled with the liquid and screwed together, until the upper end of the mouth part 1 of the container body A comes into contact with the gasket P on the underside of the closing wall 80 of the dropper stopper body G with a pressure deformation part inside the cap part F, and as the screwing proceeds further, the upper end of the mouth part 1 pushes up the closing wall 80 of the dropper stopper body G with a pressure deformation part, crushing and deforming the vertical bellows part 85 of the vertical pressure deformation part 83, causing a volume reduction inside the vertical pressure deformation part 83. As the vertical pressure-deformation portion 83 is crushed and reduced in volume, the air within the dropper plug G with the pressure-deformation portion is pushed out from the lower end of the nozzle portion 81 into the container body A. When the screwing is completed and the lid is closed, as shown in FIG. 8, the vertical pressure deformation portion 83 of the dropper plug G with pressure deformation portion is crushed, and the lid is closed in a reduced volume state.
[0056] To use the container of this embodiment, first, the container is held upright and the cap portion F is rotated relative to the container body A. When the cap portion F is opened, the cap portion F rises relative to the container body A, and the crushed vertically pressed deformed portion 83 is pushed back to its original shape as the cap portion F abuts against the underside of the top wall 70. In addition, as the vertical pressure deformation portion 83 is returned to its original shape, the dropper stopper body G with the pressure deformation portion is pressed downward, pushing the dropper stopper body G with the pressure deformation portion downward within the cap portion F, and pressing the lower surface of the closure wall 80 against the upper end surface of the nozzle portion 1 until the cap portion F has finished being unscrewed and opened.
[0057] As the vertical pressure deformation portion 83 is returned to its original shape, the volume within the vertical pressure deformation portion 83 is returned to its original state, and negative pressure is created within the dropper stopper body G with the pressure deformation portion by the amount of the reduction in volume, and the content liquid is sucked up into the nozzle portion 81 from the lower end of the nozzle portion 81.
[0058] As shown in FIG. 10, the liquid contents sucked up into the nozzle portion 81 can be discharged from the lower end of the nozzle portion 81 through the lower end of the nozzle portion 81 by pressing inward the push button portion 89 of the lateral pressure deformation portion 84 which protrudes out from within the lateral peripheral wall 74 of the side peripheral wall 71 of the cap portion F, thereby crushing and deforming the lateral bellows portion 88 of the lateral pressure deformation portion 84, causing the inside of the lateral pressure deformation portion 84 to reduce in volume. The air within the dropper stopper body G with the pressure deformation portion is pushed out through the lateral opening 84a, and the liquid contents sucked up into the nozzle portion 81 can be discharged from the lower end of the nozzle portion 81 and used. [Industrial Applicability]
[0059] The container with a dropper of the present invention can be used by rotating the cap to draw up and store a predetermined amount of the liquid contents within the container body into the dropper plug in the cap, and by pressing the push button that protrudes from the side of the cap, the liquid contents can be ejected, making it suitable as a container with a dropper that can be operated and used with one hand.
