Description

Dispensing container

[0001] The present invention relates to a dispenser that dispenses viscous application substances such as lip balm, lipstick, glue, etc.

[0002] Conventionally, as shown in Figure 40, there has been known a dispensing container of this type which is a synthetic resin molded product and which comprises a bottomed outer tube 101, a cap 102 which is detachably attached to the upper outer wall of the outer tube 101, an inner tube 103 which is detachably inserted into the upper inner wall of the outer tube 101, a guide tube 105 which is detachably inserted into the lower inner wall of the inner tube 103 and has a screw thread 104 formed on the inner wall, and a receiving tray 107 which has a screw tube 106 below which screws onto the screw thread 104 of the guide tube 105 (Patent Document 1).

[0003] In such conventional dispensing containers, the viscous coating material supported on the tray 107 is raised and lowered along the inner cylinder 103, so that the dispensing function is not affected even if the viscosity of the viscous coating material is low.

[0004] Furthermore, as an example of this type of dispensing container, as shown in Figure 41, there is one that is a synthetic resin molded product and is composed of a main body 111, a cap 112 that is detachable and attachable to the upper outer wall of the main body 111, an operating member 113 that is rotatably inserted into the lower inner wall of the main body 111, a shaft member 114 that is inserted inside the main body 111, and a middle tray member 115 that is screwed onto the shaft member 114 and moves up and down within the main body 111 (Patent Document 2).

[0005] Such conventional dispensing containers move the viscous coating material placed on the inner tray member 115 up and down along the shaft member 114, and are therefore said to be able to effectively dispense highly viscous coating materials.

[0006] JP 2014-188260 A JP 2020-32104 A

[0007] However, the dispensing container described in Patent Document 1 is composed of five components: an outer tube 101, a cap 102, an inner tube 103, a guide tube 105, and a receiving tray 107, and is made of a synthetic resin molded product, which increases the cost of creating the molding die and results in high manufacturing costs.

[0008] Furthermore, the dispensing container described in Patent Document 2 is also composed of five components: a main body 111, a cap 112, an operating member 113, a shaft member 114, and an inner tray member 115, and is made of a synthetic resin molded product, which increases the cost of creating the molding die and results in high manufacturing costs.

[0009] Furthermore, in the dispensing container described in Patent Document 2, an axial member 114 is inserted inside the main body 111, which reduces the internal volume of the main body 111 due to this axial member 114, thereby reducing the internal volume of the viscous coating material.In addition, if the viscosity of the viscous coating material is low, the viscous coating material is prone to breaking, which interferes with the dispensing function.

[0010] Furthermore, in the dispensing container described in Patent Document 1, the viscous coating material supported on the receiving tray 107 is raised and lowered, so if the viscosity of the viscous coating material is low, there is no problem when raising it, but when lowering it, the viscous coating material remains stuck to the inner wall of the inner tube 103 and does not come off, which causes the viscous coating material to break midway, hindering the dispensing function again.

[0011] Therefore, the present invention aims to solve these conventional problems and to provide a dispensing container that reduces the cost of creating the molding die by reducing the number of components, lowers manufacturing costs, does not reduce the amount of viscous coating material contained, and does not impair the dispensing function even if the viscosity of the viscous coating material is low.

[0012] Another object of the present invention is to provide a dispensing container in which the molding dies for the internal threaded portion provided in the internal hole of the support pillar of the outer tube and the external threaded portion provided on the outer peripheral wall of the support shaft of the receiving material can be easily machined, and which has good machining accuracy and requires short machining time.

[0013] Furthermore, the present invention aims to provide a dispensing container that does not require screwing when threading the external thread portion on the outer wall of the support shaft of the receiving material into the internal thread portion on the internal hole of the support pillar of the outer tube, thereby saving time and making assembly easy.

[0014] Therefore, the dispensing container of the present invention is a synthetic resin molded product composed of a cap 1, an outer tube 2, an inner tube 3, and a receiving member 4. The cap 1 is a cylindrical body having a top surface 11, and its lower end is detachably attached to the upper end of the outer tube 2. The outer tube 2 is a cylindrical body having a bottom surface 21, and a vertically elongated support post 25 having an external thread portion 24 on its outer wall is erected at the center of the bottom surface 21. The inner tube 3 is rotatable at its lower portion and inserted into the upper part of the outer tube 2. The receiving member 4 has a receiving tray 41 at its upper portion and a support shaft 43 at its lower portion. The receiving tray 41 supports the lower portion of the viscous coating material M filled in the inner tube 3 and moves up and down along the inner wall of the inner tube 3. The support shaft 43 has an internal bore with an internal thread portion 45. An internal thread portion 45 provided in the hole inside the support shaft 43 is screwed into an external thread portion 24 provided on the outer peripheral wall of the support pillar 25 of the outer tube 2, thereby allowing the receiving material 4 to be raised and lowered.

[0015] In the dispensing container of the present invention, a circumferential groove 23 is provided on the inner circumferential wall at the upper end of the outer tube 2, and an engaging rib 33 is provided on the outer circumferential wall at the lower part of the inner tube 3, so that this engaging rib 33 fits loosely into the circumferential groove 23.

[0016] In the dispensing container of the present invention, the inner tube 3 has a horizontal cross-sectional shape of the lower inner wall that is a shape other than a perfect circle, and the receiving material 4 has a horizontal cross-sectional shape of the outer wall of the support shaft 43 that matches the horizontal cross-sectional shape of the inner wall of the inner tube 3.

[0017] The dispensing container of the present invention is a synthetic resin molded product comprising a cap 1, an outer tube 2, an inner tube 3, and a receiving member 4. The cap 1 is a cylinder having a top surface 11, and its lower end is detachably attached to the upper end of the outer tube 2. The outer tube 2 is a cylinder having a bottom surface 21, and its inner peripheral wall is provided with ratchet teeth 26 that constitute a ratchet mechanism in conjunction with a ratchet pawl 36 provided on the inner tube 3. A vertically elongated support post 25 having an external thread 24 on its outer peripheral wall is erected at the center of the bottom surface 21. The inner tube 3 is rotatably inserted into the outer tube 2, and its lower part is provided with the ratchet teeth 26 that constitute the ratchet mechanism in conjunction with the ratchet pawl 36 provided on the inner peripheral wall of the outer tube 2. The receiving member 4 has a receiving tray 41 at its upper part and a support shaft 43 at its lower part. The receiving tray 41 supports the lower part of the viscous coating material M filled in the inner tube 3. The support shaft 43 has an internal hole provided with an internal thread 45. The internal thread 45 is threadedly engaged with the external thread 24 provided on the outer peripheral wall of the support 25 of the outer cylinder 2, and the outer cylinder 2 is rotated by the ratchet mechanism only in the direction in which the viscous application material M is dispensed, thereby lifting the receiving material 4 and dispensing the viscous application material M.

[0018] In the dispensing container of the present invention, the ratchet teeth 26 of the outer tube 2 are elongated teeth having sliding surfaces 26a inclined at an obtuse angle and locking surfaces 26b inclined at an acute angle, and are provided in large numbers on the inner peripheral wall of the outer tube 2 at positions corresponding to the ratchet pawls 36 provided on the inner tube 3. The ratchet pawls 36 of the inner tube 3 consist of an elastic curved piece 36a provided at the bottom and a pawl portion 36b protruding radially outward from the tip of the elastic curved piece 36a. When the outer tube 2 is rotated in the direction of dispensing the viscous coating material M, the pawl portion 36b of the ratchet pawl 36 slides on the sliding surfaces 26a of the ratchet teeth 26, allowing the outer tube 2 to rotate. Even if the outer cylinder 2 is rotated in the feeding direction of the viscous coating material M, the claw portion 36b of the ratchet claw 36 hits the engaging surface 26a of the ratchet tooth 26, making it impossible to rotate the outer cylinder 2.

[0019] In the dispensing container of the present invention, the inner tube 3 has a horizontal cross-sectional shape of the lower inner wall that is a shape other than a perfect circle, and the receiving material 4 has a horizontal cross-sectional shape of the outer wall of the support shaft 43 that matches the horizontal cross-sectional shape of the inner wall of the inner tube 3.

[0020] Furthermore, the dispensing container of the present invention is a synthetic resin molded product comprising a cap 1, an outer tube 2, an inner tube 3, and a receiving member 4. The cap 1 is a cylinder having a top surface 11, and its lower end is detachably attached to the upper end of the outer tube 2. The outer tube 2 is a cylinder having a bottom surface 21, and a vertically elongated support post 25 is erected in the center of the bottom surface 21. The support post 25 has an internal thread 27 extending throughout the entire internal hole. The inner tube 3 is rotatable at its lower portion and inserted into the upper part of the outer tube 2. The receiving member 4 has a receiving tray 41 at its upper portion and a support shaft 43 extending downward from its lower portion. The receiving tray 41 supports the lower portion of the viscous coating material M filled in the inner tube 3 and moves up and down along the inner peripheral wall of the inner tube 3. The support shaft 43 has an external thread 46 at a portion of the lower part of the outer peripheral wall. The outer threaded portion 46 of the support shaft 43 is screwed into the inner threaded portion 27 of the support column 25 of the outer cylinder 2, and the outer cylinder 2 is rotated to move the receiving member 4 up and down.

[0021] In the dispensing container of the present invention, the inner tube 3 has a horizontal partition 37 on its lower inner wall, which has an insertion hole 38 formed therein and shaped to have parallel opposing surfaces 38a, 38a, and the support shaft 43 of the receiving material 4 has a horizontal cross-sectional shape on its outer wall which has parallel opposing surfaces 43a, 43a that slide against the parallel opposing surfaces 38a, 38a of the insertion hole 38 of the horizontal partition 37 of the inner tube 3, and is shaped so that it can be inserted into this insertion hole 38.

[0022] The dispensing container of the present invention is a synthetic resin molded product comprising a cap 1, an outer tube 2, an inner tube 3, and a receiving member 4. The cap 1 is a cylinder having a top surface 11, and its lower end is detachably attached to the upper end of the outer tube 2. The outer tube 2 is a cylinder having a bottom surface 21, and a vertically elongated support post 25 is erected in the center of the bottom surface 21. The support post 25 has an internal thread 27 extending throughout its entire internal hole. The inner tube 3 is rotatable, with its lower portion inserted into the upper portion of the outer tube 2. The receiving member 4 has a tray 41 at its upper portion and a support shaft 43 extending downward from its lower portion. The support shaft 43 has an external thread 46 only on the lower portion of its outer peripheral wall. A kerf 47 is formed in the external thread 46 so that the external thread 46 can be expanded or contracted radially. The tray 41 supports the lower portion of the viscous coating material M filled in the inner cylinder 3 and moves up and down along the inner peripheral wall of the inner cylinder 3 .

[0023] Furthermore, the dispensing container of the present invention is a synthetic resin molded product comprising a cap 1, an outer tube 2, an inner tube 3, and a receiving member 4. The cap 1 is a cylindrical body having a top surface 11, and its lower end is detachably attached to the upper end of the outer tube 2. The outer tube 2 is a cylindrical body having a bottom surface 21, and a vertically elongated support post 25 is erected in the center of the bottom surface 21. The internal thread 27 is provided only at the upper part of the internal hole. A groove 28 is formed in the internal thread 27 so that the internal thread 27 can be expanded or contracted in the radial direction. The inner tube 3 is rotatable, and its lower part is inserted into the upper part of the outer tube 2. The receiving member 4 has a tray 41 at its upper part and a support shaft 43 extending downward from its lower part. The support shaft 43 is provided with an external thread 46 along the entire outer peripheral wall. The tray 41 supports the lower portion of the viscous coating material M filled in the inner cylinder 3 and moves up and down along the inner peripheral wall of the inner cylinder 3 .

[0024] In the dispensing container of the present invention, the receiving member 4 moves up and down within the inner cylinder 3 while being prevented from rotating within the inner cylinder 3.

[0025] The dispensing container of the present invention is constructed as described above and is made up of four components: cap 1, outer tube 2, inner tube 3, and receiving material 4. Therefore, compared to conventional dispensing containers, the cost of creating the molding die is reduced, resulting in lower manufacturing costs.

[0026] Furthermore, in the dispensing container of the present invention, the internal volume of the inner cylinder 3 does not decrease, and therefore the internal volume of the viscous application material M does not decrease either.

[0027] Furthermore, in the dispensing container of the present invention, the receiving member 4 moves up and down without rotating, so that even if the viscosity of the viscous application material M is low, the dispensing function is not impaired.

[0028] Furthermore, the dispensing container of the present invention is designed so that the outer tube 2 cannot be rotated in the direction of feeding the viscous coating material M, so that even if the viscosity of the viscous coating material M is low, the viscous coating material M will not come off the receiving tray 41, and there will be no interference with the dispensing function again.

[0029] Furthermore, in the dispensing container of the present invention, the molding die that forms the internal thread portion 27 provided throughout the entire internal hole of the support 25 of the outer tube 2 and the external thread portion 46 provided on a portion of the lower part of the outer peripheral wall of the support shaft 43 of the receiving material 4 can be easily machined, has good machining accuracy, and requires short machining time.

[0030] Furthermore, with the dispensing container of the present invention, the external thread portion 46 provided only on the lower part of the support shaft 43 of the receiving material 4 can be quickly and easily screwed onto the internal thread portion 27 provided on the entire support pillar 25 of the outer tube 2, or the external thread portion 46 provided on the entire support shaft 43 can be simply pushed into the internal thread portion 27 provided on only the upper part of the support pillar 25, thereby shortening the assembly time and making the assembly easy.

[0032] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the dispensing container of the present invention will be described in detail with reference to the drawings.

[0033] 1 to 6 show a first embodiment of the dispensing container of the present invention.

[0034] The dispensing container of the present invention is a synthetic resin molded product, and as shown in the figure, is composed of a cap 1, an outer cylinder 2, an inner cylinder 3, and a receiving member 4.

[0035] As shown in Figures 2 to 4, the cap 1 is a cylindrical body having a top surface 11, and an engaging rib 12 is provided on the inner peripheral wall of the lower end, so that the lower end can be freely attached and detached to the upper end of the outer tube 2.

[0036] 2 to 4, the outer cylinder 2 is a cylinder having a bottom surface 21 and an outer diameter equal to that of the cap 1. A stepped cylinder 22 is provided at the upper end of the outer cylinder 2. The lower end of the cap 1 is inserted into the stepped cylinder 22 at the upper end of the outer cylinder 2, so that the boundary between the cap 1 and the outer cylinder 2 is flush. A circumferential groove 23 is provided on the inner peripheral wall at the upper end of the outer cylinder 2. Furthermore, a vertically long support post 25 having an external thread portion 24 on its outer peripheral wall is erected in the center of the bottom surface 21 of the outer cylinder 2.

[0037] 2 to 4, the inner cylinder 3 is a cylinder with a smaller diameter than the outer cylinder 2, and an engaging rib 33 is provided on the outer peripheral wall of the lower part of the inner cylinder 3, and the horizontal cross section of the inner peripheral wall of the lower part is a shape other than a perfect circle, such as a drum shape, D-shape, oval shape, polygonal shape, etc. The engaging rib 33 of the inner cylinder 3 is loosely fitted into the circumferential groove 23 of the outer cylinder 2, so that the lower part of the inner cylinder 3 is rotatable and inserted into the upper part of the outer cylinder 2.

[0038] As shown in Figures 2 to 4, the receiving material 4 has a tray 41 at its upper part and a support shaft 43 at its lower part via a stepped portion 42. The tray 41 supports the lower part of the viscous coating material M filled in the inner tube 3 and allows it to move up and down along the inner circumferential wall of the inner tube 3. The support shaft 43 has an outer circumferential wall whose horizontal cross-sectional shape matches the horizontal cross-sectional shape of the inner circumferential wall of the inner tube 3, and an internal thread 45 is provided in its internal hole. The internal thread 45 is threadedly engaged with the external thread 24 provided on the outer circumferential wall of the support 25 of the outer tube 2, and the receiving material 4 is raised and lowered by rotating the outer tube 2 forward and backward. As a result, the viscous coating material M filled in the tray 41 of the receiving material 4 moves up and down along the inner circumferential wall of the inner tube 3.

[0039] The dispensing container of the first embodiment of the present invention is assembled in the following procedure.

[0040] First, insert the receiving material 4 from above the inner tube 3 so that the horizontal cross-sectional shape of the inner wall at the lower part of the inner tube 3 matches the horizontal cross-sectional shape of the support shaft 43 of the receiving material 4, and abut the step portion 42 of the receiving material 4 against the upper end of the inner wall at the lower part of the inner tube 3.

[0041] Next, from above the outer tube 2, the internal thread portion 45 provided in the internal hole of the support shaft 43 of the receiving material 4 is screwed into the external thread portion 24 provided on the outer peripheral wall of the support pillar 25 of the outer tube 2, and the lower end of the support shaft 43 is abutted against the bottom surface 21 of the outer tube 2.

[0042] Furthermore, the viscous coating material M is filled from above the inner cylinder 3 into the receiving tray 41 of the receiving material 4 so that it slightly protrudes above the inner cylinder 3.

[0043] Then, the cap 1 is inserted from above the inner tube 3 so that the engaging rib 12 at the lower end of the cap 1 contacts the stepped tube 22 at the upper end of the outer tube 2, and the cap 1 is attached to the outer tube 2.

[0044] The dispensing container of the first embodiment of the present invention is configured as described above and is used as follows.

[0045] First, the outer tube 2 of the dispensing container of the present invention is held in the hand in the state shown in FIGS.

[0046] Next, the inner tube 3 is pinched with the fingers of one hand, the outer tube 2 is pinched with the fingers of the other hand, and the outer tube 2 is rotated in the forward direction. This causes the inner screw portion 45 provided in the hole inside the support shaft 43 of the receiving material 4 to rise along the outer screw portion 24 provided on the outer peripheral wall of the support 25 of the outer tube 2, and the receiving tray 41 of the receiving material 4 also rises, and the upper end of the viscous application material M is exposed above the inner tube 3, as shown in Figure 5, and the material can be used in this state.

[0047] After use, when the outer tube 2 is rotated in the reverse direction, the inner screw portion 45 provided in the hole inside the support shaft 43 of the receiving material 4 descends along the outer screw portion 24 provided on the outer peripheral wall of the support 25 of the outer tube 2, so that the receiving tray 41 of the receiving material 4 also descends, and the upper end of the viscous application substance M exposed at the upper end of the inner tube 3 enters into the inner tube 3.

[0048] Furthermore, even when the outer tube 2 is rotated forward or backward, the horizontal cross-sectional shape of the inner wall at the bottom of the inner tube 3 matches the horizontal cross-sectional shape of the outer wall of the support shaft 43 of the receiving material 4, so rotation of the support shaft 43 of the receiving material 4 is prevented, and the receiving material 4 moves up and down without following the forward or backward rotation of the outer tube 2.

[0049] Then, by reattaching the cap 1 removed from the outer tube 2 to the outer tube 2, the original state shown in Figures 1 and 3 is restored, and the viscous coating material M can be stored in a state where it is less likely to dry out or become contaminated.

[0050] Therefore, since the dispensing container of the first embodiment of the present invention is composed of four parts: cap 1, outer tube 2, inner tube 3, and receiving material 4, the cost of creating the molding die is reduced compared to conventional dispensing containers, resulting in lower manufacturing costs, and since no shaft member is inserted inside the inner tube 3 as in conventional cases, the internal volume of the inner tube 3 does not decrease, and the internal volume of the viscous application material M does not decrease either.

[0051] Furthermore, the dispensing container of the first embodiment of the present invention is configured so that the receiving material 4 can move up and down without rotating forward and backward in accordance with the forward and reverse rotation of the outer tube 2, thereby having the excellent effect of not interfering with the dispensing function even if the viscosity of the viscous application material M is low.

[0052] 7 to 13 show a second embodiment of the dispensing container of the present invention.

[0053] The dispensing container of the present invention is a synthetic resin molded product, and as shown in the figure, is composed of a cap 1, an outer cylinder 2, an inner cylinder 3, and a receiving member 4.

[0054] As shown in Figures 8 to 10, the cap 1 is a cylindrical body having a top surface 11, and an engaging rib 12 is provided on the inner peripheral wall of the lower end, so that the lower end can be freely attached and detached to the upper end of the outer tube 2.

[0055] As shown in Figures 8 to 10, the outer tube 2 is a cylinder having a bottom surface 21 and an outer diameter equal to that of the cap 1. A stepped tube 22 with a smaller diameter is provided at the upper end of the outer tube 2. The lower end of the cap 1 is inserted into the stepped tube 22 of the outer tube 2, so that the boundary between the cap 1 and the outer tube 2 is flush. A circumferential groove 23 is provided on the inner peripheral wall at the upper end of the outer tube 2, and ratchet teeth 26 that constitute a ratchet mechanism with a ratchet pawl 36 provided on the inner tube 3 (described later) are provided on the inner peripheral wall below the circumferential groove 23. As shown in Figures 10 and 13, the ratchet teeth 26 are elongated teeth having a sliding surface 26a inclined at an obtuse angle and a locking surface 26b inclined at an acute angle, and are provided in large numbers on the inner peripheral wall of the outer tube 2 at positions corresponding to the ratchet pawl 36 provided on a second stepped tube 35 of the inner tube 3 (described later). Although the ratchet teeth 26 need only be provided on the inner peripheral wall of the outer tube 2 at positions corresponding to the ratchet pawl 36 provided on the second stepped tube 35 of the inner tube 3, due to the molding process of the synthetic resin, they are provided downward from that corresponding position. This ratchet mechanism is designed so that when the outer tube 2 is rotated in the direction of the arrow in Figure 13 (the direction in which the viscous coating material M is dispensed, as described below), the pawl portion 36b of the ratchet pawl 36 slides along the sliding surface 26a of the ratchet teeth 26, allowing the outer tube 2 to rotate, but when the outer tube 2 is rotated in the direction opposite to the arrow in Figure 13 (the direction in which the viscous coating material M is fed, as described below), the pawl portion 36b of the ratchet pawl 36 comes into contact with the engaging surface 26a of the ratchet teeth 26, preventing the outer tube 2 from rotating. Furthermore, a vertically long support 25 having an externally threaded portion 24 on its outer peripheral wall is erected in the center of the bottom surface 21 of the outer cylinder 2 .

[0056] 8 to 10, the inner cylinder 3 is a cylinder with a smaller diameter than the outer cylinder 2, and its lower portion is rotatably inserted into the outer cylinder 2. A first stepped cylinder 32 with a smaller diameter is provided at the lower portion via a first stepped portion 31, and an engaging rib 33 is provided on the outer peripheral wall of the first stepped cylinder 32. The first stepped cylinder 32 of the inner cylinder 3 has an inner peripheral wall whose horizontal cross section has a shape other than a perfect circle, such as a drum shape, a D-shape, an oval shape, or a polygonal shape. A second stepped cylinder 35 with an even smaller diameter is provided below the first stepped cylinder 32 of the inner cylinder 3 via a second stepped portion 34, and a ratchet pawl 36 that constitutes a ratchet mechanism in conjunction with the ratchet teeth 26 provided on the inner peripheral wall of the outer cylinder 2 is provided at the bottom of this second stepped cylinder 35. The ratchet pawl 36 is made up of a pair of opposing elastic curved pieces 36a provided at the bottom of the second stepped cylinder 35, and a pawl portion 36b protruding radially outward from the tip of the elastic curved piece 36a. The engaging rib 33 of the inner cylinder 3 is loosely fitted into the circumferential groove 23 of the outer cylinder 2, making the lower part of the inner cylinder 3 rotatable, and by inserting it into the upper part of the outer cylinder 2, the ratchet pawl 36 of the inner cylinder 3 engages with the ratchet teeth 26 of the outer cylinder, thereby forming a ratchet mechanism.

[0057] As shown in Figures 8 to 10, the receiving material 4 has a tray 41 at its upper end whose outer diameter is the same as the inner diameter of the inner tube 3, and a support shaft 43 with a smaller diameter at its lower end via a stepped portion 42. The tray 41 has multiple vertical ribs 44 radially arranged on its inner peripheral wall, and the lower portion of the viscous coating material M filled in the inner tube 3 is pressed into these vertical ribs 44 to firmly support it, allowing the viscous coating material M to rise along the inner peripheral wall of the inner tube 3. The support shaft 43 has an outer peripheral wall whose horizontal cross-sectional shape matches that of the inner peripheral wall of the inner tube 3, and an internal hole provided with an internal thread 45. The internal thread 45 is threadedly engaged with the external thread 24 on the outer peripheral wall of the support post 26 of the outer tube 2, and the outer tube 2 is rotated by the ratchet mechanism only in the direction in which the viscous coating material M is dispensed, thereby lifting the receiving material 4. As a result, the viscous coating material M supported on the receiving tray 41 of the receiving material 4 rises along the inner peripheral wall of the inner cylinder 3 and is dispensed.

[0058] The dispensing container of the second embodiment of the present invention configured as described above is assembled in the following procedure.

[0059] First, insert the receiving material 4 from above the inner tube 3 so that the horizontal cross-sectional shape of the inner wall of the first step tube 32 of the inner tube 3 matches the horizontal cross-sectional shape of the outer wall of the support shaft 43 of the receiving material 4.

[0060] Next, the internal thread portion 45 provided in the internal hole of the support shaft 43 of the receiving material 4 inserted into the inner tube 3 from above the outer tube 2 is screwed into the external thread portion 24 provided on the outer peripheral wall of the support pillar 25 of the outer tube 2 until the lower end of the support shaft 43 abuts against the bottom surface 21 of the outer tube 2.

[0061] Then, the claw portion 36b of the ratchet pawl 36 of the inner tube 3 slides and rotates along the sliding surface 26a of the ratchet tooth 26 of the outer tube 2, and the first step portion 31 of the inner tube 3 abuts against the upper end of the step tube 22 of the outer tube 2, and the engagement rib 33 of the inner tube 3 is loosely fitted into the circumferential groove 23 of the outer tube 2.

[0062] The viscous coating material M is then filled from above the inner cylinder 3 up to the upper end of the inner cylinder 3 , whereby the viscous coating material M is supported on the receiving tray 41 of the receiving material 4 .

[0063] Furthermore, the cap 1 is inserted from above the inner tube 3, and the cap 1 is attached to the outer tube 2 so that the engaging rib 12 at the lower end of the cap 1 contacts the outer peripheral wall of the stepped tube 22 at the upper end of the outer tube 2, and the assembly is completed as shown in Figures 7 and 11.

[0064] The dispensing container of the second embodiment of the present invention assembled in the above-described manner is used as follows.

[0065] First, the outer tube 2 of the dispensing container of the present invention is held in the hand in the state shown in FIGS.

[0066] Next, if the inner tube 3 is pinched with the fingers of one hand and the outer tube 2 with the fingers of the other hand and an attempt is made to rotate the outer tube 2 in the direction of the arrow in the figure (the direction in which the viscous coating material M is dispensed) as shown in Figure 13, the claw portion 36b of the ratchet pawl 36 will slide along the sliding surface 26a of the ratchet tooth 26, causing the outer tube 2 to rotate, and the internal thread portion 45 provided in the hole inside the support shaft 43 of the receiving material 4 will rise along the external thread portion 24 provided on the outer peripheral wall of the support 25 of the outer tube 2, so that the receiving tray 41 of the receiving material 4 will also rise, and the upper end of the viscous coating material M will be exposed above the inner tube 3 as shown in Figure 12, and the device can be used in this state. When the outer tube 2 is rotated, the horizontal cross-sectional shape of the inner wall of the first step tube 32 of the inner tube 3 matches the horizontal cross-sectional shape of the outer wall of the support shaft 43 of the receiving material 4, so the receiving material 4 also rises without rotating in response to the rotation of the outer tube 2, and the upper end of the viscous coating substance M supported on the receiving tray 41 of the receiving material 4 can be smoothly exposed.

[0067] After use, if the cap 1 removed from the outer tube 2 is attached to the outer tube 2 again, the original state shown in Figures 7 and 11 is restored, and the viscous coating material M can be stored in a state where it is less likely to dry out or become contaminated.

[0068] Furthermore, even if one attempts to rotate the outer tube 2 in the direction opposite to the arrow in Figure 13 (the direction in which the viscous coating material M is fed in) before reattaching the cap 1 to the outer tube 2 after use, the claw portion 36b of the ratchet pawl 36 will come into contact with the engaging surface 26a of the ratchet tooth 26, preventing the outer tube 2 from rotating, and the internal thread portion 45 provided in the hole inside the support shaft 43 of the receiving material 4 cannot be lowered along the external thread portion 24 provided on the outer peripheral wall of the support 25 of the outer tube 2, and the receiving tray 41 of the receiving material 4 cannot be lowered either.Therefore, even if the viscosity of the viscous coating material M supported on the receiving tray 41 is low, the viscous coating material M will not break midway.

[0069] Therefore, since the dispensing container of the second embodiment of the present invention is composed of four parts: cap 1, outer tube 2, inner tube 3, and receiving material 4, the cost of creating the molding die is reduced compared to conventional dispensing containers, resulting in lower manufacturing costs.Furthermore, since no shaft member is inserted inside the inner tube 3 as in conventional dispensing containers, the internal volume of the inner tube 3 does not decrease, and the internal volume of the viscous application substance does not decrease either.

[0070] Furthermore, the dispensing container of the second embodiment of the present invention is designed so that the outer tube 2 cannot be rotated in the direction of dispensing the viscous coating material M, even when the viscosity of the viscous coating material M is low, so that the viscous coating material M will not come off the receiving tray 41 and will not interfere with the dispensing function again.

[0071] 14 to 21 show a third embodiment of the dispensing container of the present invention.

[0072] The dispensing container of the present invention is a synthetic resin molded product, and as shown in the figure, is composed of a cap 1, an outer cylinder 2, an inner cylinder 3, and a receiving member 4.

[0073] As shown in FIGS. 15 to 17, the cap 1 is a cylindrical body having a top surface 11, and its lower end is detachably attached to the upper end of the outer cylinder 2.

[0074] 15 to 17, the outer cylinder 2 is a cylinder having a bottom surface 21, and its outer diameter is the same as that of the cap 1. A stepped cylinder 22 with a smaller diameter is provided at the top of the outer cylinder 2, and a circumferential groove 23 is provided on the inner peripheral wall of the stepped cylinder 22. The lower end of the cap 1 is inserted into the stepped cylinder 22 of the outer cylinder 2, so that the boundary between the cap 1 and the outer cylinder 2 is flush. In addition, a vertically long support post 25 having an internal thread 27 extending over the entire internal hole is erected in the center of the bottom surface 21 of the outer cylinder 2.

[0075] The molding die for forming the internal thread portion 27 provided throughout the entire internal hole of the support 25 of the outer tube 2 mainly consists of a rod-shaped male die 14 having the external thread portion 13 formed on the outer peripheral wall, a first female die 16 having a cylindrical first cavity 15 formed on the inner peripheral wall, and a second female die 18 having a cylindrical second cavity 17 formed on the inner peripheral wall, as shown in Figure 20(a). To form the external thread portion 13 in the male die 14, as shown in Figure 20(b), a cutting tool C is pressed directly against the outer peripheral wall of the male die 14, both ends of the male die 14 are fixed, and the male die 14 is rotated.

[0076] Therefore, to form the external thread portion 13 on the male die 14, the cutting tool C is simply pressed against the outer peripheral wall of the male die 14, and both ends of the male die 14 can be easily fixed, so that the axial wobble of the rotating shaft is less likely to occur and the processing accuracy is improved.

[0077] 15 to 17, the inner cylinder 3 is a cylindrical body with a smaller diameter than the outer cylinder 2, and a stepped cylinder 30 with an even smaller diameter is provided at the bottom of the inner cylinder 3. An engaging rib 33 is provided on the outer peripheral wall of the upper part of the stepped cylinder 30, and a horizontal partition wall 37 is provided on the inner peripheral wall below the engaging rib 33. As shown in FIG. 19, this horizontal partition wall 37 is formed with an insertion hole 38 having parallel opposing surfaces 38a, 38a in a horizontal cross section that is drum-shaped, elliptical, or the like. The engaging rib 33 of the inner cylinder 3 is loosely fitted into the circumferential groove 23 of the outer cylinder 2, allowing the lower part of the inner cylinder 3 to rotate freely and be inserted into the upper part of the outer cylinder 2.

[0078] 15 to 17, the receiving material 4 has a tray 41 at its upper end with an outer diameter equal to the inner diameter of the inner tube 3, and a support shaft 43 with a smaller diameter than the tray 41 suspended from its lower part via a stepped portion 42. The tray 41 has a plurality of vertical ribs 44 radially arranged on its inner peripheral wall, and the lower part of the viscous coating material M filled in the inner tube 3 is pressed into these vertical ribs 44 to firmly support it, allowing the viscous coating material M to move up and down along the inner peripheral wall of the inner tube 3. As shown in FIG. 19, the horizontal cross-sectional shape of the outer peripheral wall of the support shaft 43 has parallel opposing surfaces 43a, 43a that slide against the parallel opposing surfaces 38a, 38a of the insertion hole 38 in the horizontal partition wall 37 of the inner tube 3, and the support shaft 43 is shaped so as to be insertable into this insertion hole 38, and an external thread portion 46 is provided in a portion of the lower part of the outer peripheral wall. The outer threaded portion 46 is threaded into an inner threaded portion 27 provided over the entire area of ​​the hole inside the support 25 of the outer tube 2, and the receiving material 4 is raised and lowered by rotating the outer tube 2 forward and backward. As a result, the viscous coating material M filled in the receiving tray 41 of the receiving material 4 rises and falls along the inner peripheral wall of the inner tube 3.

[0079] The molding die for forming the external thread portion 46 provided on a portion of the lower part of the outer peripheral wall of the support shaft 43 suspended below the receiving material 4, as shown in Figures 21(a) and (b), mainly consists of a first split mold 54 in which half of the internal thread portion 53 is formed at the bottom of an approximately semi-cylindrical cavity 52a having a parallel opposing surface 51a formed on the inner peripheral wall, and a second split mold 55 in which another half of the internal thread portion 53 is formed at a portion of the bottom of an approximately semi-cylindrical cavity 52b having a parallel opposing surface 51a formed on the inner peripheral wall, and the internal thread portion 53 is formed when the first split mold 54 and the second split mold 55 are opened.

[0080] Therefore, to form the internal thread portion 53 in the first split mold 54 and the second split mold 55, a cutting tool is pressed against a part of the lower part of each of the first split mold 54 and the second split mold 55 in the open state, and this cutting tool is rotated. Since both ends of these split molds can also be easily fixed, processing accuracy is good and processing time is short.

[0081] The dispensing container of the third embodiment of the present invention is assembled in the following procedure.

[0082] First, the receiving material 4 is inserted from above the inner tube 3 so that the parallel opposing surfaces 38a, 38a of the insertion hole 38 of the horizontal partition 37 of the inner tube 3 and the parallel opposing surfaces 43a, 43a of the support shaft 43 of the receiving material 4 are in sliding contact with each other, and the external thread portion 46 provided on a part of the lower outer wall of the support shaft 43 of the receiving material 4 is screwed into the internal thread portion 27 provided throughout the entire internal hole of the support pillar 25 of the outer tube 2, and the receiving material 4 is lowered until the lower end of the support shaft 43 approaches or abuts the bottom surface 21 of the outer tube 2.

[0083] Next, the viscous application material M is filled from above the inner cylinder 3 up to the upper end of the inner cylinder 3 , and the viscous application material M is supported on the receiving tray 41 of the receiving member 4 .

[0084] Then, the cap 1 is inserted from above the inner tube 3, and the lower end of the cap 1 is inserted into the stepped tube 22 of the outer tube 2 so that the boundary between the cap 1 and the outer tube 2 is flush with one another, and the cap 1 is attached to the outer tube 2.

[0085] The dispensing container of the third embodiment of the present invention as described above is used as follows.

[0086] First, the outer tube 2 of the dispensing container of the present invention is held in the hand in the state shown in FIGS. 14 and 17, and the cap 1 is picked up with the fingers to remove the cap 1 from the outer tube 2.

[0087] Next, the inner tube 3 is pinched with the fingers of one hand and the outer tube 2 is pinched with the fingers of the other hand, and the outer tube 2 is rotated in the forward direction. This causes the outer thread portion 46 provided on a part of the lower outer wall of the support shaft 43 of the receiving material 4 to rise along the inner thread portion 27 provided throughout the entire internal hole of the support 25 of the outer tube 2, and the receiving tray 41 of the receiving material 4 also rises, and the upper end of the viscous application substance M is exposed above the inner tube 3, as shown in Figure 18, and the material can be used in this state.

[0088] After use, when the outer tube 2 is rotated in the reverse direction, the outer thread portion 46 provided on a part of the lower outer wall of the support shaft 43 of the receiving material 4 descends along the inner thread portion 27 provided over the entire area of ​​the internal hole of the support pillar 25 of the outer tube 2, so that the receiving tray 41 of the receiving material 4 also descends and the upper end of the viscous application substance M exposed at the upper end of the inner tube 3 enters the inner tube 3.

[0089] Furthermore, even when the outer tube 2 is rotated forward or backward, the parallel opposing surfaces 38a, 38a of the insertion hole 38 of the horizontal partition 37 of the inner tube 3 and the parallel opposing surfaces 43a, 43a of the support shaft 43 of the receiving material 4 are in sliding contact with each other, so the receiving material 4 moves up and down while being prevented from rotating.Even if the viscous application material M supported on the receiving tray 41 of the receiving material 4 has a low viscosity, the viscous application material M will not come off the receiving tray 41 and the dispensing function will not be impaired.

[0090] Then, by reattaching the cap 1 removed from the outer tube 2 to the outer tube 2, the original state shown in Figures 14 and 17 is restored, and the viscous coating material M can be stored in a state where it is less likely to dry out or become contaminated.

[0091] The dispensing container of the third embodiment of the present invention is configured as described above, and in addition to the effects of the dispensing container of the first embodiment, the molding die that forms the internal thread portion 27 provided throughout the entire internal hole of the support 25 of the outer tube 2 and the external thread portion 46 provided on a portion of the lower outer wall of the support shaft 43 of the receiving material 4 can be easily machined, has good machining accuracy, and requires short machining time.

[0092] Furthermore, as mentioned above, in the dispensing container of the present invention, the receiving material 4 moves up and down without rotating, so that even if the viscosity of the viscous application material M is low, the dispensing function is not impaired.

[0093] 22 to 27 show a fourth embodiment of the dispensing container of the present invention, which is a synthetic resin molded product comprising a cap 1, an outer cylinder 2, an inner cylinder 3 and a receiving member 4. In the fourth embodiment of the dispensing container of the present invention, as shown in FIG.

[0094] As shown in the figure, the cap 1 is a cylindrical body having a top surface 11, and an engaging rib 12 is provided on the inner peripheral wall of the lower end, so that the lower end can be freely attached and detached to the upper end of the outer tube 2.

[0095] As shown in the figure, the outer cylinder 2 is a cylinder having a bottom surface 21, and its outer diameter is the same as that of the cap 1. A stepped cylinder 22 with a smaller diameter is provided at the top of the outer cylinder 2, and a circumferential groove 23 is provided on the inner peripheral wall of the stepped cylinder 22. The lower end of the cap 1 is inserted into the stepped cylinder 22 of the outer cylinder 2, so that the boundary between the cap 1 and the outer cylinder 2 is flush. In addition, a vertically long support post 25 having an internal thread portion 27 extending over the entire internal hole is erected in the center of the bottom surface 21 of the outer cylinder 2.

[0096] As shown in the figure, the inner cylinder 3 is a cylindrical body with a smaller diameter than the outer cylinder 2. A stepped cylinder 30 with an even smaller diameter is provided at the bottom of the inner cylinder 3. An engagement rib 33 is provided on the outer peripheral wall of the upper part of the stepped cylinder 30, and a horizontal partition wall 37 is provided on the inner peripheral wall below the engagement rib 33. As shown in Figure 27, this horizontal partition wall 37 is formed with an insertion hole 38 having a horizontal cross-sectional shape with parallel opposing surfaces 38a, 38a, such as an oval or elliptical shape. Note that the insertion hole 38 may have a horizontal cross-sectional shape that is a partial circle or simply a circle. The engagement rib 33 of the inner cylinder 3 is loosely fitted into the circumferential groove 23 of the outer cylinder 2, so that the lower part of the inner cylinder 3 is rotatably inserted into the upper part of the outer cylinder 2.

[0097] As shown in the figure, the receiving material 4 has a tray 41 at its upper end with an outer diameter equal to the inner diameter of the inner tube 3 provided at its upper end, and a support shaft 43 with a smaller diameter than the tray 41 suspended from its lower part via a stepped portion 42. The tray 41 has a plurality of vertical ribs 44 radially formed on its inner peripheral wall, and the lower part of the viscous coating material M filled in the inner tube 3 is pressed into these vertical ribs 44 to firmly support it, allowing the viscous coating material M to move up and down along the inner peripheral wall of the inner tube 3. As shown in Figure 27, the horizontal cross-sectional shape of the outer peripheral wall of the support shaft 43 has parallel opposing surfaces 43a, 43a that slide against the parallel opposing surfaces 38a, 38a of the insertion hole 38 in the horizontal partition wall 37 of the inner tube 3, and the support shaft 43 is shaped so as to be insertable into this insertion hole 38, and an external thread portion 46 is provided only on the lower part of the outer peripheral wall. The horizontal cross-sectional shape of the support shaft 43 is a circular or semicircular shape that can be inserted into the insertion hole 38 if the horizontal cross-sectional shape of the insertion hole 38 is a semicircular or semicircular shape. Furthermore, the external thread portion 46 is formed with an axial groove 47 that divides the external thread portion 46 into two, allowing it to expand and contract radially. While the illustrated groove 47 divides the external thread portion 46 into two, it may be divided into three or more, as needed. The external thread portion 46 is threadedly engaged with the internal thread portion 27 extending throughout the entire internal hole of the support post 25 of the outer tube 2, as described below. The receiving material 4 is raised and lowered by rotating the outer tube 2 forward and backward. As a result, the viscous coating material M filled in the receiving tray 41 of the receiving material 4 moves up and down along the inner peripheral wall of the inner tube 3 while being prevented from rotating within the inner tube 3.

[0098] The dispensing container shown as the fourth embodiment of the present invention is assembled in the following procedure.

[0099] First, the receiving material 4 is inserted from above the inner tube 3 so that the parallel opposing surfaces 38a, 38a of the insertion hole 38 of the horizontal partition 37 of the inner tube 3 and the parallel opposing surfaces 43a, 43a of the support shaft 43 of the receiving material 4 are in sliding contact with each other, and the lower end of the external thread portion 46 provided only on the lower part of the outer wall of the support shaft 43 of the receiving material 4 is pressed against the upper part of the internal thread portion 27 provided throughout the entire internal hole of the support pillar 25 of the outer tube 2.

[0100] Then, the groove 47 formed in the external thread portion 46 of the support shaft 43 narrows, and the external thread portion 46 shrinks in the radial direction, so that the external thread portion 46 is pushed into the internal thread portion 27 of the support 25 of the outer tube 2, and the receiving material 4 is lowered until the lower end of the support shaft 43 approaches or abuts against the bottom surface 21 of the outer tube 2.

[0101] Then, when the external thread portion 46 of the support shaft 43 is stopped from being pushed into the internal thread portion 27 of the support pillar 25 of the outer tube 2, the groove 47 widens at that position, and the external thread portion 46 expands radially, so that the external thread portion 46 screws into the internal thread portion 27.

[0102] Therefore, the external thread portion 46 of the support shaft 43 can be quickly and easily screwed into the internal thread portion 27 by simply pushing the external thread portion 46 into the internal thread portion 27, without having to screw the external thread portion 46 of the support shaft 43 from the top to the bottom of the internal thread portion 27 of the support pillar 25 of the outer cylinder 2.

[0103] Next, the viscous application material M is filled from above the inner cylinder 3 up to the upper end of the inner cylinder 3 , and the viscous application material M is supported on the receiving tray 41 of the receiving member 4 .

[0104] Then, the cap 1 is inserted from above the inner tube 3, and the lower end of the cap 1 is inserted into the stepped tube 22 of the outer tube 2 so that the boundary between the cap 1 and the outer tube 2 is flush with one another, and the cap 1 is attached to the outer tube 2.

[0105] The dispensing container shown as the fourth embodiment of the present invention as described above is used as follows.

[0106] First, the outer tube 2 of the dispensing container of the present invention is held in the hand in the state shown in FIG. 25, and the cap 1 is picked up with the fingers to remove the cap 1 from the outer tube 2.

[0107] Next, the inner tube 3 is pinched with the fingers of one hand and the outer tube 2 is pinched with the fingers of the other hand, and the outer tube 2 is rotated in the forward direction. This causes the outer thread portion 46, which is provided only on the lower part of the outer wall of the support shaft 43 of the receiving material 4, to rise along the inner thread portion 27, which is provided throughout the entire internal hole of the support 25 of the outer tube 2. As a result, the receiving tray 41 of the receiving material 4 also rises, and the upper end of the viscous application substance M is exposed above the inner tube 3, as shown in Figure 26, and the material can be used in this state.

[0108] After use, when the outer tube 2 is rotated in the reverse direction, the outer thread portion 46 provided only on the lower part of the outer peripheral wall of the support shaft 43 of the receiving material 4 descends along the inner thread portion 27 provided over the entire area of ​​the internal hole of the support 25 of the outer tube 2, so that the receiving tray 41 of the receiving material 4 also descends, and the upper end of the viscous application substance M exposed at the upper end of the inner tube 3 enters into the inner tube 3.

[0109] Furthermore, even when the outer tube 2 is rotated forward or backward, the parallel opposing surfaces 38a, 38a of the insertion hole 38 of the horizontal partition 37 of the inner tube 3 and the parallel opposing surfaces 43a, 43a of the support shaft 43 of the receiving material 4 are in sliding contact with each other, so the receiving material 4 moves up and down within the inner tube 3 while being prevented from rotating within the inner tube 3.This means that even if the viscous application material M supported on the receiving tray 41 of the receiving material 4 has a low viscosity, the viscous application material M will not come off the receiving tray 41 and will not interfere with the dispensing function.

[0110] Then, by reattaching the cap 1 removed from the outer tube 2 to the outer tube 2, the original state shown in Figure 25 is restored, and the viscous coating material M can be stored in a state where it is less likely to dry out or become contaminated.

[0111] The dispensing container of the fourth embodiment of the present invention is configured as described above, and in addition to the effects of the dispensing container of the first embodiment, the external threaded portion 46 can be quickly and easily screwed into the internal threaded portion 27 of the support pillar 25 of the outer tube 2 by simply pushing the external threaded portion 46 into the internal threaded portion 27, without having to screw the external threaded portion 46 of the support shaft 43 of the receiving material 4 from the top to the bottom of the internal threaded portion 27.

[0112] Furthermore, in the dispensing container of the fourth embodiment of the present invention, the external thread portion 46 is provided only on the lower part of the outer wall of the support shaft 43 of the receiving material 4, so the mold for forming this receiving material 4 can be easily processed, has good processing accuracy, and requires a short processing time.

[0113] 28 to 33 show a fifth embodiment of the dispensing container of the present invention, which is a synthetic resin molded product made up of a cap 1, an outer cylinder 2, an inner cylinder 3, and a receiving member 4.

[0114] As shown in the figure, the cap 1 is a cylindrical body having a top surface 11, and its lower end is detachably attached to the upper end of the outer cylinder 2.

[0115] As shown in the figure, the outer tube 2 is a cylinder having a bottom surface 21 and an outer diameter equal to that of the cap 1. The outer tube 2 has a stepped tube 22 with a smaller diameter at its upper portion, and a circumferential groove 23 on the inner peripheral wall of the upper portion. The lower end of the cap 1 is inserted into the stepped tube 22 of the outer tube 2, so that the boundary between the cap 1 and the outer tube 2 is flush with each other. A vertically elongated support 25 is erected in the center of the bottom surface 21 of the outer tube 2, and an internal thread portion 27 is provided only at the upper portion of the internal bore. Furthermore, an axial kerf 28 is formed in the internal thread portion 27, dividing it into two forks so that the internal thread portion 27 can be expanded or contracted radially. While the illustrated kerf 28 divides the internal thread portion 27 into two forks, it may also divide it into three or more forks, if necessary.

[0116] As shown in the figure, the inner cylinder 3 is a cylinder with a smaller diameter than the outer cylinder 2. A stepped cylinder 30 with an even smaller diameter is provided at the bottom of the inner cylinder 3. An engaging rib 33 is provided on the outer peripheral wall of this stepped cylinder 30, and a horizontal partition wall 37 is provided on the inner peripheral wall above this engaging rib 33. As shown in Figure 33, this horizontal partition wall 37 has an insertion hole 38 with a circular horizontal cross section. The engaging rib 33 of the inner cylinder 3 is loosely fitted into the circumferential groove 23 of the outer cylinder 2, so that the lower part of the inner cylinder 3 is inserted into the upper part of the outer cylinder 2 in a rotatable manner. In addition, two vertical ribs 39 extending linearly in the vertical direction are provided opposite each other on the inner peripheral wall of the inner cylinder 3.

[0117] As shown in the figure, the receiving material 4 has a tray 41 at its upper end whose outer diameter is the same as the inner diameter of the inner tube 3, and a support shaft 43 with a smaller diameter than the tray 41 suspended from its lower part via a stepped portion 42. The tray 41 has multiple vertical ribs 44 radially arranged on its inner peripheral wall, and the lower part of the viscous coating material M filled in the inner tube 3 is pressed into these vertical ribs 44 to firmly support it, allowing the viscous coating material M to move up and down along the inner peripheral wall of the inner tube 3. The tray 41 also has vertical grooves 48 on its outer peripheral wall into which the vertical ribs 39 on the inner peripheral wall of the inner tube 3 fit loosely. The support shaft 43 has a circular horizontal cross section and an external thread 46 running along the entire outer peripheral wall. Then, as will be described later, this external threaded portion 46 is threaded into an internal threaded portion 27 provided only at the upper portion of the hole inside the support 25 of the outer cylinder 2, and the receiving material 4 is raised and lowered by rotating the outer cylinder 2 forward and backward. As a result, the viscous coating material M filled in the receiving tray 41 of the receiving material 4 is raised and lowered within the inner cylinder 3 along the inner peripheral wall while being prevented from rotating within the inner cylinder 3.

[0118] The dispensing container shown as the fifth embodiment of the present invention is assembled in the following procedure.

[0119] First, insert the receiving material 4 from above the inner tube 3 so that the vertical rib 39 on the inner peripheral wall of the inner tube 3 fits loosely into the vertical groove 48 on the receiving tray 41 of the receiving material 4, and press the lower end of the external thread portion 46 provided on the entire outer peripheral wall of the support shaft 43 of the receiving material 4 against the internal thread portion 27 provided only at the top of the internal hole of the support 25 of the outer tube 2.

[0120] Then, the groove 28 formed in the internal thread portion 27 of the support 25 widens, and the internal thread portion 27 expands radially. Then, the external thread portion 46 of the support shaft 43 of the receiving material 4 is pushed into the internal thread portion 27 of the support 25, and the receiving material 4 is lowered until the lower end of the support shaft 43 approaches or abuts against the bottom surface 21 of the outer tube 2.

[0121] Then, when the external thread portion 46 of the support shaft 43 is stopped from being pushed into the internal thread portion 27 of the support pillar 25 of the outer tube 2, the groove 28 narrows at that position, and the internal thread portion 27 shrinks radially, so that the external thread portion 46 screws into the internal thread portion 27.

[0122] Therefore, the outer screw portion 46 of the support shaft 43 can be quickly and easily screwed into the inner screw portion 27 by simply pushing the outer screw portion 46 into the inner screw portion 27, without having to screw the outer screw portion 46 of the support shaft 43 from the bottom to the top into the inner screw portion 27 of the support 25 of the outer cylinder 2.

[0123] Next, the viscous application material M is filled from above the inner cylinder 3 up to the upper end of the inner cylinder 3 , and the viscous application material M is supported on the receiving tray 41 of the receiving member 4 .

[0124] Then, the cap 1 is inserted from above the inner tube 3, and the lower end of the cap 1 is inserted into the stepped tube 22 of the outer tube 2 so that the boundary between the cap 1 and the outer tube 2 is flush with one another, and the cap 1 is attached to the outer tube 2.

[0125] The dispensing container shown as the fifth embodiment of the present invention as described above is used in the following manner, in substantially the same manner as the dispensing container shown as the fourth embodiment.

[0126] First, the outer tube 2 of the dispensing container of the present invention is held in the hand in the state shown in FIG. 31, and the cap 1 is picked up with the fingers to remove the cap 1 from the outer tube 2.

[0127] Next, the inner tube 3 is pinched with the fingers of one hand and the outer tube 2 is pinched with the fingers of the other hand, and the outer tube 2 is rotated in the forward direction. This causes the outer thread portion 46 provided on the entire outer wall of the support shaft 43 of the receiving material 4 to rise along the inner thread portion 27 provided only at the top of the internal hole of the support 25 of the outer tube 2, and the receiving tray 41 of the receiving material 4 also rises, and the upper end of the viscous application substance M is exposed above the inner tube 3, as shown in Figure 32, and the material can be used in this state.

[0128] After use, when the outer tube 2 is rotated in the reverse direction, the outer thread portion 46 provided on the entire outer wall of the support shaft 43 of the receiving material 4 descends along the inner thread portion 27 provided only on the upper part of the internal hole of the support 25 of the outer tube 2, so that the receiving tray 41 of the receiving material 4 also descends, and the upper end of the viscous application substance M exposed at the upper end of the inner tube 3 enters into the inner tube 3.

[0129] Furthermore, even when the outer tube 2 is rotated forward or backward, the vertical ribs 39 on the inner wall of the inner tube 3 fit loosely into the vertical grooves 48 on the receiving tray 41 of the receiving material 4, so that the receiving material 4 moves up and down within the inner tube 3 while being prevented from rotating within the inner tube 3.Even if the viscous application material M supported on the receiving tray 41 of the receiving material 4 has a low viscosity, the viscous application material M will not come off the receiving tray 41, and the dispensing function will not be impaired.

[0130] Then, by reattaching the cap 1 removed from the outer tube 2 to the outer tube 2, the original state shown in Figure 31 is restored, and the viscous coating material M can be stored in a state where it is less likely to dry out or become contaminated.

[0131] The dispensing container of the fifth embodiment of the present invention is configured as described above, and in addition to the effects of the dispensing container of the first embodiment, the external threaded portion 46 can be quickly and easily screwed into the internal threaded portion 24 by simply pushing the external threaded portion 46 into the internal threaded portion 27, without having to screw the external threaded portion 46 of the support shaft 43 of the receiving material 4 from the bottom to the top into the internal threaded portion 27 of the support pillar 25 of the outer tube 2.

[0132] Furthermore, in the dispensing container of the fifth embodiment of the present invention, the internal thread portion 27 is provided only at the upper portion of the internal hole of the support 25 of the outer tube 2, so the mold for forming this outer tube 2 can be easily machined, has good machining accuracy, and requires a short machining time.

[0133] 34 to 39 show a sixth embodiment of the dispensing container of the present invention, which is a synthetic resin molded product made up of a cap 1, an outer cylinder 2, an inner cylinder 3, and a receiving member 4.

[0134] As shown in the figure, the cap 1 is a cylindrical body having a top surface 11, and its lower end is detachably attached to the upper end of the outer cylinder 2.

[0135] As shown in the figure, the outer tube 2 is a cylinder having a bottom surface 21 and an outer diameter equal to that of the cap 1. The outer tube 2 has a stepped tube 22 with a smaller diameter at its upper portion, and a circumferential groove 23 on the inner peripheral wall of the upper portion. The lower end of the cap 1 is inserted into the stepped tube 22 of the outer tube 2, so that the boundary between the cap 1 and the outer tube 2 is flush with each other. A vertically elongated support 25 is erected in the center of the bottom surface 21 of the outer tube 2, and an internal thread portion 27 is provided only at the upper portion of the internal bore. Furthermore, an axial kerf 28 is formed in the internal thread portion 27, dividing the internal thread portion 27 into three trifurcated portions so as to radially expand and contract the internal thread portion 27. While the illustrated kerf 28 divides the internal thread portion 27 into three trifurcated portions, it may also divide the internal thread portion 27 into two bifurcated portions, as in the fifth embodiment, or into more than three bifurcated portions. Furthermore, the internal thread portion 27 has a small meshing gap with the external thread portion 46 provided on the support shaft 43 of the receiving material 4 described later, and may interfere when the receiving material 4 is raised or lowered, so it is preferable to make the screw end narrower.

[0136] As shown in the figure, the inner tube 3 is a cylindrical body with a smaller diameter than the outer tube 2. A stepped tube 30 with an even smaller diameter is provided at the bottom of the inner tube 3. An engaging rib 33 is provided on the outer peripheral wall of the stepped tube 30, and a horizontal partition wall 37 is provided on the inner peripheral wall above the engaging rib 33. As shown in Figure 39, the horizontal partition wall 37 is formed with an insertion hole 38 having a horizontal cross-sectional shape with parallel opposing surfaces 38a, 38a, such as an oval or elliptical shape. The insertion hole 38 may also have a horizontal cross-sectional shape that is a partial circle or simply a circle. The engaging rib 33 of the inner tube 3 is loosely fitted into the circumferential groove 23 of the outer tube 2, allowing the lower part of the inner tube 3 to be rotatably inserted into the upper part of the outer tube 2.

[0137] As shown in the figure, the receiving material 4 has a tray 41 at its upper end whose outer diameter is the same as the inner diameter of the inner tube 3, and a support shaft 43 with a smaller diameter than the tray 41 suspended from its lower part via a stepped portion 42. The tray 41 has a plurality of vertical ribs 44 radially formed on its inner peripheral wall, and the lower part of the viscous coating material M filled in the inner tube 3 is pressed into these vertical ribs 44 to firmly support it, allowing the viscous coating material M to move up and down along the inner peripheral wall of the inner tube 3. As shown in Figure 39, the horizontal cross-sectional shape of the outer peripheral wall of the support shaft 43 has parallel opposing surfaces 43a, 43a that slide against the parallel opposing surfaces 38a, 38a of the insertion hole 38 in the horizontal partition wall 37 of the inner tube 3, and the support shaft 43 is shaped so that it can be inserted into this insertion hole 38, and an external thread portion 46 is provided on the entire outer peripheral wall except for the parallel opposing surfaces 43a, 43a. If the horizontal cross section of the insertion hole 38 is a notched circle or a circle, the support shaft 43 has a notched circle or a circle shape that can be inserted into the insertion hole 38. The external threaded portion 46 is threadedly engaged with the internal threaded portion 27 provided only at the upper portion of the internal hole of the support 25 of the outer tube 2 as will be described later, and the receiving material 4 is raised and lowered by rotating the outer tube 2 forward and backward. As a result, the viscous coating material M filled in the receiving tray 41 of the receiving material 4 rises and lowers within the inner tube 3 along the inner peripheral wall while being prevented from rotating within the inner tube 3.

[0138] The dispensing container shown as the sixth embodiment of the present invention is assembled in the following procedure.

[0139] First, the receiving material 4 is inserted from above the inner tube 3 so that the parallel opposing surfaces 38a, 38a of the insertion hole 38 of the horizontal partition 37 of the inner tube 3 and the parallel opposing surfaces 43a, 43a of the support shaft 43 of the receiving material 4 are in sliding contact with each other, and the lower end of the external thread portion 46 provided on the entire outer wall of the support shaft 43 of the receiving material 4 is pressed against the internal thread portion 27 provided only on the upper part of the internal hole of the support pillar 25 of the outer tube 2.

[0140] Then, the groove 28 formed in the internal thread portion 27 of the support 25 widens, and the internal thread portion 27 expands radially. Then, the external thread portion 46 of the support shaft 43 of the receiving material 4 is pushed into the internal thread portion 27 of the support 25, and the receiving material 4 is lowered until the lower end of the support shaft 43 approaches or abuts against the bottom surface 21 of the outer tube 2.

[0141] Then, when the external thread portion 46 of the support shaft 43 is stopped from being pushed into the internal thread portion 27 of the support pillar 25 of the outer cylinder 2, the groove 28 narrows at that position and the internal thread portion 27 shrinks in the radial direction, so that the internal thread portion 27 screws into the external thread portion 46.

[0142] Therefore, the outer screw portion 46 of the support shaft 43 can be quickly and easily screwed into the inner screw portion 27 by simply pushing the outer screw portion 46 into the inner screw portion 27, without having to screw the outer screw portion 46 of the support shaft 43 from the bottom to the top into the inner screw portion 27 of the support 25 of the outer cylinder 2.

[0143] Next, the viscous application material M is filled from above the inner cylinder 3 up to the upper end of the inner cylinder 3 , and the viscous application material M is supported on the receiving tray 41 of the receiving member 4 .

[0144] Then, the cap 1 is inserted from above the inner tube 3, and the lower end of the cap 1 is inserted into the stepped tube 22 of the outer tube 2 so that the boundary between the cap 1 and the outer tube 2 is flush with one another, and the cap 1 is attached to the outer tube 2.

[0145] The dispensing container shown as the sixth embodiment of the present invention as described above is used in the following manner, in substantially the same manner as the dispensing containers shown as the fourth and fifth embodiments.

[0146] First, the outer tube 2 of the dispensing container of the present invention is held in the hand in the state shown in FIG. 37, and the cap 1 is picked up with the fingers to remove the cap 1 from the outer tube 2.

[0147] Next, the inner tube 3 is pinched with the fingers of one hand and the outer tube 2 is pinched with the fingers of the other hand, and the outer tube 2 is rotated in the forward direction. This causes the outer thread portion 46 provided on the entire outer wall of the support shaft 43 of the receiving material 4 to rise along the inner thread portion 27 provided only at the top of the internal hole of the support 25 of the outer tube 2, and the receiving tray 41 of the receiving material 4 also rises, and the upper end of the viscous application substance M is exposed above the inner tube 3, as shown in Figure 38, and the material can be used in this state.

[0148] After use, when the outer tube 2 is rotated in the reverse direction, the outer thread portion 46 provided on the entire outer wall of the support shaft 43 of the receiving material 4 descends along the inner thread portion 27 provided only on the upper part of the support 25 of the outer tube 2, so that the receiving tray 41 of the receiving material 4 also descends, and the upper end of the viscous coating substance M exposed at the upper end of the inner tube 3 enters into the inner tube 3.

[0149] Furthermore, even when the outer tube 2 is rotated forward or backward, the parallel opposing surfaces 38a, 38a of the insertion hole 38 of the horizontal partition 37 of the inner tube 3 and the parallel opposing surfaces 43a, 43a of the support shaft 43 of the receiving material 4 are in sliding contact with each other, so the receiving material 4 moves up and down within the inner tube 3 while being prevented from rotating within the inner tube 3.This means that even if the viscous application material M supported on the receiving tray 41 of the receiving material 4 has a low viscosity, the viscous application material M will not come off the receiving tray 41 and will not interfere with the dispensing function.

[0150] Then, by reattaching the cap 1 that was removed from the outer tube 2 to the outer tube 2, the original state shown in Figure 37 is restored, and the viscous coating material M can be stored in a state where it is less likely to dry out or become contaminated.

[0151] The dispensing container of the sixth embodiment of the present invention is configured as described above, and in addition to the effects of the dispensing container of the first embodiment, the external threaded portion 46 can be quickly and easily screwed into the internal threaded portion 24 by simply pushing the external threaded portion 46 into the internal threaded portion 27, without having to screw the external threaded portion 46 of the support shaft 43 of the receiving material 4 from the bottom to the top into the internal threaded portion 27 of the support pillar 25 of the outer tube 2.

[0152] Furthermore, in the dispensing container of the sixth embodiment of the present invention, the internal thread portion 27 is provided only at the upper portion of the internal hole of the support 25 of the outer tube 2, so the mold for forming this outer tube 2 can be easily machined, has good machining accuracy, and requires a short machining time.
