Description

[Technical Field]

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

[0002] Conventionally, as shown in FIG. 7, there is a dispensing container of this type which is a synthetic resin molded product and comprises a bottomed outer tube 31, a cap 32 which is detachably attached to the upper outer wall of the outer tube 31, an inner tube 33 which is detachably inserted into the upper inner wall of the outer tube 31, a guide tube 35 which is detachably inserted into the lower inner wall of the inner tube 33 and has a screw thread 34 formed on the inner wall, and a receiving tray 37 which has a screw tube 36 below which screws onto the screw thread 34 of the guide tube 35 (Patent Document 1).

[0003] Such conventional dispensing containers have the advantage that the viscous coating material supported on the receiving tray 37 is raised and lowered along the inner tube 33, so that the dispensing function is not impaired 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 8, there is one that is a synthetic resin molded product and is composed of a main body 41, a cap 42 that is detachably attached to the upper outer wall of the main body 41, an operating member 43 that is rotatably inserted into the lower inner wall of the main body 41, a shaft member 44 that is inserted inside the main body 41, and an inner tray member 45 that is screwed onto the shaft member 44 and moves up and down inside the main body 41 (Patent Document 2).

[0005] Such conventional dispensing containers have the advantage that they can effectively dispense highly viscous coating substances because the viscous coating substance placed on the inner tray member 45 is raised and lowered along the shaft member 44. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2014-188260 A [Patent Document 2] JP 2020-32104 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, the dispensing container described in Patent Document 1 is composed of five components: an outer tube 31, a cap 32, an inner tube 33, a guide tube 35, and a receiving tray 37, and is made of a synthetic resin molded product, which poses the problem of high manufacturing costs due to the high cost of creating the molding die.

[0008] Furthermore, the dispensing container described in Patent Document 2 is also composed of five components: a main body 41, a cap 42, an operating member 43, a shaft member 44, and an inner tray member 45, and is molded from synthetic resin, which increases the cost of creating the molding die, resulting in high manufacturing costs.

[0009] Furthermore, in the dispensing container described in Patent Document 2, an axial member 44 is inserted inside the main body 41, which reduces the internal volume of the main body 41 due to this axial member 44, 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] 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. [Means for solving the problem]

[0011] Therefore, 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 tube 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 13, and a vertically elongated support post 17 having a screw thread 16 on its outer peripheral wall is erected in the center of the bottom surface 13. The inner tube 3 has a rotatable lower portion inserted into the upper part of the outer tube 2. The receiving tube 4 has a receiving tray 19 on its upper portion and a screw tube 21 on its lower portion. The receiving tray 19 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 screw tube 21 has a screw groove 22 on its inner peripheral wall. The thread groove 22 provided on the inner peripheral wall of the screw cylinder 21 is screwed with the thread 16 provided on the outer peripheral wall of the support 17 of the outer cylinder 2, allowing the receiving cylinder 4 to move up and down.

[0012] In the dispensing container of the present invention, a circumferential groove 15 is provided on the inner circumferential wall at the upper end of the outer tube 2, and an engaging rib 18 is provided on the outer circumferential wall at the lower part of the inner tube 3, and this engaging rib 18 is adapted to fit loosely into the circumferential groove 16.

[0013] 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 other than a perfect circle, and the receiving tube 4 has a horizontal cross-sectional shape of the outer wall of the screw tube 21 that matches the horizontal cross-sectional shape of the inner wall of the inner tube 3. [Effects of the Invention]

[0014] The dispensing container of the present invention is configured as described above and is composed of four components: cap 1, outer tube 2, inner tube 3, and receiving tube 4. Therefore, compared to conventional dispensing containers, the cost of creating the molding die is reduced, resulting in lower manufacturing costs.

[0015] Furthermore, in the dispensing container of the present invention, the internal volume of the inner cylinder 3 does not decrease, and therefore the internal amount of the viscous application substance M does not decrease either.

[0016] Furthermore, in the dispensing container of the present invention, the receiving tube 4 moves up and down without rotating forward or backward, so that even if the viscosity of the viscous application material M is low, the dispensing function is not impaired.

[0018] 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.

[0019] 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 cylinder 4.

[0020] As shown in Figures 2 to 4, the cap 1 is a cylinder 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 to and detached from the upper end of the outer tube 2.

[0021] As shown in Figures 2 to 4, the outer cylinder 2 is a cylinder having a bottom surface 13 and an outer diameter equal to that of the cap 1. A stepped surface 14 is provided on the outer peripheral wall at the upper end of the outer cylinder 2. The lower end of the cap 1 is inserted into this stepped surface 14 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 15 is provided on the inner peripheral wall at the upper end of the outer cylinder 2. Furthermore, a vertically long support post 17 having a screw thread 16 on its outer peripheral wall is erected in the center of the bottom surface 13 of the outer cylinder 2.

[0022] 2 to 4, the inner cylinder 3 is a cylinder whose diameter is reduced by the outer cylinder 2, and an engagement rib 18 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. Then, by loosely fitting the engagement rib 18 of the inner cylinder 3 into the circumferential groove 15 of the outer cylinder 2, the lower part of the inner cylinder 3 is made rotatable and is inserted into the upper part of the outer cylinder 2.

[0023] As shown in FIGS. 2 to 4 , the receiving tube 4 has a tray 19 at its upper part and a threaded tube 21 at its lower part via a stepped portion 20. The tray 19 supports the lower part 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 threaded tube 21 has an outer peripheral wall whose horizontal cross-sectional shape matches the horizontal cross-sectional shape of the inner peripheral wall of the inner tube 3, and has a thread groove 22 formed on its inner peripheral wall. The thread groove 22 is threadedly engaged with the screw thread 16 formed on the outer peripheral wall of the support 17 of the outer tube 2, and the receiving tube 4 is moved up and down by rotating the outer tube 2 forward and backward. As a result, the viscous coating material M filled in the tray 19 of the receiving tube 4 moves up and down along the inner peripheral wall of the inner tube 3.

[0024] The dispensing container of the present invention is assembled in the following procedure.

[0025] First, insert the receiving tube 4 from above the inner tube 3 so that the horizontal cross-sectional shape of the inner peripheral wall at the lower part of the inner tube 3 matches the horizontal cross-sectional shape of the screw tube 21 of the receiving tube 4, and abut the step portion 20 of the receiving tube 4 against the upper end of the inner peripheral wall at the lower part of the inner tube 3.

[0026] Next, from above the outer tube 2, the screw thread 16 provided on the outer peripheral wall of the support 17 of the outer tube 2 is screwed into the screw groove 22 provided on the inner peripheral wall of the screw tube 21 of the receiving tube 4, and the lower end of the screw tube 21 is abutted against the bottom surface 13 of the outer tube 2.

[0027] Furthermore, the viscous coating material M is filled from above the inner cylinder 3 into the receiving tray 19 of the receiving cylinder 4 so that it slightly protrudes above the inner cylinder 3.

[0028] Then, the cap 1 is inserted from above the inner tube 3 so that the engagement rib 12 at the lower end of the cap 1 contacts the step surface 14 at the upper end of the outer tube 2, and the cap 1 is attached to the outer tube 2.

[0029] The dispensing container of the present invention is constructed as described above and is used as follows.

[0030] First, the outer tube 2 of the dispensing container of the present invention is held in the hand in the state shown in FIGS.

[0031] Next, pinch the inner tube 3 with the fingers of one hand and the outer tube 2 with the fingers of the other hand, and rotate the outer tube 2 in the forward direction. This causes the screw groove 22 on the inner wall of the screw tube 21 of the receiving tube 4 to rise along the screw thread 16 on the outer wall of the support 17 of the outer tube 2, and the receiving tray 19 of the receiving tube 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.

[0032] After use, when the outer tube 2 is rotated in the reverse direction, the screw groove 22 provided on the inner peripheral wall of the screw tube 21 of the receiving tube 4 descends along the screw thread 16 provided on the outer peripheral wall of the support 17 of the outer tube 2, so that the receiving tray 19 of the receiving tube 4 also descends, and the upper end of the viscous coating substance M exposed at the upper end of the inner tube 3 enters the inner tube 3.

[0033] 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 screw tube 21 of the receiving tube 4, so rotation of the screw tube 21 of the receiving tube 4 is prevented, and the receiving tube 4 can move up and down without following the forward or backward rotation of the outer tube 2.

[0034] Then, by reattaching the cap 1 that was 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.

[0035] As described above, the dispensing container of the present invention is composed of four components: cap 1, outer tube 2, inner tube 3, and receiving tube 4. Therefore, compared to conventional dispensing containers, the cost of creating the molding die is reduced, resulting in lower manufacturing costs. Furthermore, since no shaft member is inserted inside the inner tube 3 as in the conventional case, the internal volume of the inner tube 3 does not decrease, and the internal volume of the viscous application substance does not decrease either.

[0036] Furthermore, the dispensing container of the present invention is designed so that the receiving tube 4 can move up and down without rotating forward and backward in response to 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.
