Description

Technical Field

[0001] The present invention relates to a feeding container configured to feed viscous coating substances such as lip cream, lipstick, paste, etc.

Background Art

[0002] Conventionally, as a feeding container of this type, for example, as shown in FIG. 13, there is one composed of a screw cylinder 22 provided with a screw groove 21 on the peripheral wall and integrally erected at the center of the bottom surface of an outer cylinder 23, a tray 24 locked and fixed to the upper end of the screw cylinder 22 and storing a viscous coating substance M, a screw wall 26 provided with a thread 25 engaging with the screw groove 21 of the screw cylinder 22 on the entire inner peripheral wall surface at the bottom surface, an inner cylinder 27 interposed between the outer cylinder 23 and the tray 24 and moving up and down along the inner surface of the outer cylinder 23, and a cap 28 covering the outer cylinder 23 (Patent Document 1).

[0003] [[ID= 16]]The feeding container is assembled by inserting the inner cylinder 27 into the outer cylinder 23, screwing the thread of the screw wall 26 into the screw groove 21 of the screw cylinder 22, and forcibly inserting and locking the lower locking piece 29 of the tray 24 into the hole 30 of the screw cylinder to fix the tray 24 to the outer cylinder 23.

[0004] Then, as shown in FIG. 14, the feeding container can be used by removing the cap 28 from the outer cylinder 23, pressing and rotating the outer wall of the inner cylinder 27 with a fingertip, so that the screw wall 26 moves up and down along the screw cylinder 22, moving the inner cylinder 27 up and down, and exposing the viscous coating substance M stored in the tray 24.

[0005] [[ID= 23]] The feeding container configured as described above is convenient because it can be moved up and down along the outer cylinder 23 by only holding and rotating the inner cylinder 27 with a fingertip, and appropriately exposing the viscous coating substance M stored inside the container for use.

[0006] Furthermore, the dispensing container is stable because the screw cylinder 22 is integrally provided with the outer cylinder 23, and the screw wall 26 of the inner cylinder 27 moves up and down while being fully screwed with the screw threads 25 of the screw cylinder 22, which has the effect of reducing malfunctions. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Public Gazette No. 50-35905 [Overview of the project] [Problems that the invention aims to solve]

[0008] However, in the dispensing container described in Patent Document 1, the screw cylinder 22 is integrally provided with the outer cylinder 23, so the screw cylinder 22 cannot be removed. Furthermore, the lower locking piece 29 of the receiving tray 24 containing the viscous coating material M is forcibly inserted into the hole 30 of the screw cylinder 22 and locked in place, so the receiving tray 24 containing the viscous coating material M cannot be removed from the screw cylinder 22. Therefore, after the viscous coating material M is used up, it cannot be replaced, and the dispensing container itself must be discarded, which presents a problem in that no measures have been taken to address environmental issues.

[0009] Therefore, the present invention aims to solve the problems of the past by providing a dispensing container in which the screw cylinder and the outer cylinder are separate, the screw cylinder can be removed from the outer cylinder, and the tray containing the viscous coating material can be removed from the screw cylinder, so that even after the viscous coating material has been used up, the entire dispensing container does not have to be discarded, and the viscous coating material can be replaced by separating and discarding a part of the dispensing container as plastic waste, thereby contributing to environmental protection to some extent. [Means for solving the problem]

[0010] The dispensing container of the present invention consists of a cap 1, an outer cylinder 2, an inner cylinder 3, a receiving tray 4, and a screw cylinder 5. 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. The outer cylinder 2 is a cylindrical body, and the lower part of the screw cylinder 5 is detachably fitted into the lower part of its inner circumferential wall. The inner cylinder 3 is a cylindrical body that is detachably inserted into the outer cylinder 2, and has a screw-fitting portion 16 formed at its lower end. The receiving tray 4 is a receiving body having a bottom surface 17, into which a viscous coating substance M can be loaded, and has an insertion portion 18 formed at its lower end that is detachably inserted into the inner cylinder 3 and detachably inserted into the screw cylinder 5. The screw cylinder 5 has screw grooves 19 formed on its entire outer circumferential wall, and the screw-fitting portion 16 of the inner cylinder 3 is screwed into these screw grooves 19, allowing the inner cylinder 3 to move up and down.

[0011] Furthermore, in the dispensing container of the present invention, the receiving tray 4 is inserted into the inner cylinder 3, and the threaded portion 16 of the inner cylinder 3 is screwed onto the upper part of the threaded groove 19 of the screw cylinder 5. With this in place, the viscous coating substance M is loaded into the receiving tray 4 from above the inner cylinder 3 up to the upper end of the inner cylinder 3. Next, the inner cylinder 3 loaded with the viscous coating substance M is inserted into the outer cylinder 2, and the lower part of the screw cylinder 5 is fitted into the lower part of the outer cylinder 2 in a detachable manner. Furthermore, the lower end of the cap 1 is attached to the upper end of the outer cylinder 2.

[0012] Furthermore, in the dispensing container of the present invention, with the receiving tray 4 inserted into the inner cylinder 3, the viscous coating substance M is loaded into the receiving tray 4 from above the inner cylinder 3 up to the upper end of the inner cylinder 3. Next, the threaded portion 16 of the inner cylinder 3 is screwed onto the upper part of the threaded groove 19 of the threaded cylinder 5. Furthermore, the inner cylinder 3 loaded with the viscous coating substance M is inserted into the outer cylinder 2, and the lower part of the threaded cylinder 5 is fitted into the lower part of the outer cylinder 2 in a removable manner. Finally, the lower end of the cap 1 is attached to the upper end of the outer cylinder 2.

[0013] Furthermore, in the dispensing container of the present invention, a receiving tray 4 is inserted into the inner cylinder 3, and the threaded portion 16 of the inner cylinder 3 is screwed onto the upper part of the threaded groove 19 of the screw cylinder 5. The viscous coating substance M loaded into the receiving tray 4 from above the inner cylinder 3 up to the upper end of the inner cylinder 3 is used for replacement.

[0014] Furthermore, in the dispensing container of the present invention, a detachable closing cap 6 is attached to the upper end of the inner cylinder 3.

[0015] Furthermore, in the dispensing container of the present invention, with the receiving tray 4 inserted into the inner cylinder 3, the viscous coating substance M loaded into the receiving tray 4 from above the inner cylinder 3 up to the upper end of the inner cylinder 3 is used as a replacement.

[0016] Furthermore, in the dispensing container of the present invention, detachable closing caps 6 are attached to the upper and lower ends of the inner cylinder 3, respectively. [Effects of the Invention]

[0017] The dispensing container of the present invention allows for the replacement of the viscous coating material by separating and disposing of a portion of the container as plastic waste, rather than discarding the entire container after the viscous coating material has been used up. Therefore, it can contribute to solving environmental problems to some extent. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments for carrying out the feeding container of the present invention will be described in detail based on the drawings.

[0020] As shown in Figs. 1 to 4, the feeding container of the present invention is a synthetic resin molded product composed of a cap 1, an outer cylinder 2, an inner cylinder 3, a tray 4, and a screw cylinder 5.

[0021] The cap 1 is a cylindrical body having a top surface 11, and an engaging rib 12 is formed on the inner peripheral wall at the lower end. The engaging rib 12 is engaged with and disengaged from an engaging protrusion 13a formed in a circumferential groove 13 on the outer peripheral wall at the upper end of the outer cylinder 2 described later, and the lower end thereof is detachably attached to the upper end of the outer cylinder 2.

[0022] The outer cylinder 2 is a cylindrical body with the same diameter as the cap 1, and has a circumferential groove 13 formed on the outer peripheral wall of its upper end. By inserting this circumferential groove 13 into the lower end of the cap 1, the boundary between the cap 1 and the outer cylinder 2 becomes flush when the cap 1 is attached to the outer cylinder 2. The outer cylinder 2 also has a recess 14 for fitting and unfitting the screw cylinder 5 at the lower part of its inner peripheral wall, and a fitting and unfitting projection 20 formed on the lower part of the screw cylinder 5, which will be described later, is fitted into this fitting and unfitting recess 14 in a retractable manner.

[0023] The inner cylinder 3 is a cylindrical body with a smaller diameter than the outer cylinder 2, and is removable from the outer cylinder 2. A support step 15 is formed on the lower inner circumferential wall to support the bottom surface 17 of the receiving tray 4, which will be described later, and a threaded portion 16 is formed below it for connection with the threaded groove 19 of the screw cylinder 5, which will be described later. This threaded portion 16 is a projection that moves up and down along the threaded groove 19 of the screw cylinder 5.

[0024] The receiving tray 4 is a receiving body having a bottom surface 17, and this bottom surface 17 is supported by the support step portion 15 of the inner cylinder 3. A viscous coating substance M can be loaded inside, and an insertion portion 18 is formed at the bottom that can be inserted into and removed from the inside of the inner cylinder 3 and into the inside of the screw cylinder 5.

[0025] The screw cylinder 5 is a cylindrical body with a smaller diameter than the inner cylinder 3, and the screw groove 19 is formed on the entire outer surface of the outer wall. The threaded portion 16 of the inner cylinder 3 is screwed into the screw groove 19, allowing the inner cylinder 3 to move up and down. Furthermore, a fitting projection 20 is formed at the lower part for fitting into the fitting recess 14 of the outer cylinder 2. The screw groove 19 has a recess 19a at the top that loosely fits with the threaded portion 16 of the inner cylinder 3. This recess 19a is designed so that when the threaded portion 16 is screwed into the upper part of the screw groove 19, the threaded portion 16 does not move freely, preventing it from being screwed in or detached unintentionally.

[0026] Furthermore, the dispensing container of the present invention is assembled according to the following procedure.

[0027] First, as the initial assembly procedure, the receiving tray 4 is inserted into the inner cylinder 3, and with the threaded portion 16 of the inner cylinder 3 screwed into the upper part of the threaded groove 19 of the screw cylinder 5, the viscous coating substance M is loaded into the receiving tray 4 from above the inner cylinder 3 up to the upper end of the inner cylinder 3.

[0028] Next, the inner cylinder 3, which is filled with the viscous coating substance M, is inserted into the outer cylinder 2, and the lower part of the screw cylinder 5 is removably fitted into the lower part of the removable recess 14 of the outer cylinder 2.

[0029] Furthermore, the circumferential groove 13 at the upper end of the outer cylinder 2 can be fitted into the circumferential groove 12 at the lower end of the cap 1, and the lower end of the cap 1 can be attached to the upper end of the outer cylinder 2.

[0030] Furthermore, in the second assembly procedure, with the receiving tray 4 inserted into the inner cylinder 3, the viscous coating substance M is loaded into the receiving tray 4 from above the inner cylinder 3 up to the upper end of the inner cylinder 3.

[0031] Next, the threaded portion 16 of the inner cylinder 3 is screwed onto the upper part of the threaded groove 19 of the threaded cylinder 5.

[0032] Furthermore, the inner cylinder 3, which is filled with the viscous coating substance M, is inserted into the outer cylinder 2, and the lower part of the screw cylinder 5 is removably fitted into the lower part of the removable recess 14 of the outer cylinder 2.

[0033] Finally, the circumferential groove 13 at the upper end of the outer cylinder 2 is fitted into the circumferential groove 12 at the lower end of the cap 1, and the lower end of the cap 1 is attached to the upper end of the outer cylinder 2.

[0034] Since the dispensing container of the present invention is configured as described above, it is used as follows.

[0035] First, hold the outer cylinder 2 of the dispensing container of the present invention in the state shown in Figure 1, and place your fingers on the cap 1 to remove the cap 1 from the outer cylinder 2.

[0036] Next, by pinching the inner cylinder 3 with your fingertips and rotating it, the threaded portion 16 of the inner cylinder 3 is lowered along the threaded groove 19 of the threaded cylinder 5, causing the inner cylinder 3 itself to also lower. As the inner cylinder 3 lowers, the viscous coating material M loaded into the tray 4 becomes exposed from the upper end of the inner cylinder 3, as shown in Figures 5 and 6, and can be used in this state.

[0037] Furthermore, when the viscous coating material M loaded into the receiving tray 4 of the present invention is used up, the viscous coating material M can be replaced by the following procedure.

[0038] First, as the replacement procedure, hold the outer cylinder 2 in your hand and press the upper end of the inner cylinder 3 downwards. This will release the engagement projection 15 at the bottom of the screw cylinder 5 from the engagement recess 14 at the bottom of the outer cylinder 2. Once this is done, you can remove the inner cylinder 3, along with the tray 4 and screw cylinder 5, from the outer cylinder 2. Separate and dispose of these parts as plastic waste.

[0039] Therefore, as shown in Figures 7-9, a receiving tray 4 is inserted into the inner cylinder 3, and the threaded portion 16 of the inner cylinder 3 is screwed into the upper part of the threaded groove 19 of the threaded cylinder 5. A viscous coating substance M is then loaded from above the inner cylinder 3 into the receiving tray 4 up to the upper end of the inner cylinder 3 and prepared as a replacement.

[0040] Holding the inner cylinder 3 loaded with the viscous coating material M prepared for replacement into the tray 4, insert the inner cylinder 3 into the outer cylinder 2 from below, and fit the fitting projection 15 of the screw cylinder 5 into the fitting recess 14 of the outer cylinder 2. Furthermore, by inserting the outer cylinder 2 into the cap 1, the viscous coating material M can be replaced, returning the device to its original state as shown in Figure 1.

[0041] Furthermore, the viscous coating material M prepared for replacement is stored with a removable closing cap 6 attached to the upper end of the inner cylinder 3 to prevent it from becoming contaminated or drying out. When replacing the viscous coating material M, the closing cap 6 on the upper end of the inner cylinder 3 is removed.

[0042] The second replacement procedure involves holding the outer cylinder 2 in your hand and rotating the inner cylinder 3 in the reverse thread direction. This disengages the threaded portion 16 at the bottom of the inner cylinder 3 from the upper part of the threaded groove 19 of the screw cylinder 5. Once disengaged, the inner cylinder 3, along with the receiving tray 4, can be removed from the screw cylinder 5, and these inner cylinder 3 and receiving tray 4 can then be discarded.

[0043] Therefore, as shown in Figures 10-12, with the receiving tray 4 inserted into the inner cylinder 3, a viscous coating substance M is prepared as a replacement, loaded from above the inner cylinder 3 up to the upper end of the inner cylinder 3 into the receiving tray 4.

[0044] Holding the inner cylinder 3, which has been loaded with the viscous coating material M prepared for replacement into the receiving tray 4, the threaded portion 16 of the inner cylinder 3 is screwed onto the upper part of the threaded groove 19 of the screw cylinder 5, and then the outer cylinder 2 is inserted into the cap 1, thereby replacing the viscous coating material M and returning to the original state shown in Figure 1.

[0045] Furthermore, the viscous coating material M prepared for replacement is stored with a removable closing cap 6 attached to the upper end of the inner cylinder 3 to prevent it from becoming contaminated or drying out, and a removable closing cap 6 attached to the lower end of the inner cylinder 3 to prevent the insertion portion 18 of the receiving tray 4 from being pushed back. When replacing the viscous coating material M, the closing caps 6 at the upper and lower ends of the inner cylinder 3 are removed, respectively.

[0046] As described above, the dispensing container of the present invention is configured such that even after the viscous coating material M has been used up, the entire dispensing container itself does not need to be discarded. Instead, the inner cylinder 3, receiving tray 4, and screw cylinder 5 can be discarded, or the inner cylinder 3 and receiving tray 4 can be discarded to replace the viscous coating material M. This makes a significant contribution to environmental protection. [Explanation of symbols]
