Description

Technical Field

[0005] , , ,

[0001] The present invention relates to a dispensing container, and more particularly to a dispensing container capable of dispensing contents after opening a lid simply by rotating a rotating body.

Background Art

[0002] As a container for storing rod-shaped contents such as lipsticks, lip creams, stick eyeshadows, stick foundations, etc., it consists of a case body, a rotating body, and an inner dish body for holding the contents within the case body. After removing the cap (lid), the case body is gripped and the rotating body is rotated to dispense the contents from the opening of the case body through the inner dish body for use. However, in this type of container, it was necessary to remove the cap and store it every time it was used.

[0003] For this reason, a rod-shaped cosmetic dispensing unit is housed in a main body provided with a lid that can be opened and closed by a hinge at the upper end. By rotating a cylindrical body and a base body, a rod-shaped cosmetic supported by a cosmetic holding part inserted therein moves forward and backward. There is conventionally known a capless type dispensing container that enables the forward and backward movement of the rod-shaped cosmetic by moving the rod-shaped cosmetic dispensing unit in the axial direction and protruding the cylindrical body from the main body by rotating the main body and the cylindrical body of the rod-shaped cosmetic dispensing unit (see Patent Document 1).

Summary of the Invention

[0006] The present invention aims to solve the above problems and provides a dispensing container that allows the contents to be dispensed after opening the lid with a single operation of rotating a rotating body. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides a dispensing container comprising: a case body; a rotating body rotatably mounted on the upper part of the case body; a cylindrical body rotatably mounted on the inner circumference of the case body; a tray body that is not rotatable and can move up and down, with a screw formed on its inner circumference; a shaft body that is erected from the center of the bottom of the case body and screws into the screw on the inner circumference of the tray body; and a lid body that is mounted to move up and down along the axial direction of the rotating body and opens and closes the opening of the cylindrical body. The rotating body rotates on the outer circumference of the cylindrical body, thereby raising and lowering the lid body by a predetermined stroke, and also rotates together with the cylindrical body, thereby moving the tray body up and down.

[0008] As embodiments of the dispensing container, the lid is characterized by having a cap portion that closes the opening of the cylindrical body and a lifting portion connected to the cap portion via a hinge portion that slides along the axial direction of the rotating body; or the cylindrical body is characterized by having screw threads on its outer circumference and vertical ribs protruding from the lower part of the screw threads, and the lid is characterized by having projections protruding from the inner circumference that slide in contact with the screw threads of the cylindrical body or abut against the vertical ribs; or the rotating body is characterized by having a notch cut out in the vertical direction from the upper end and a pair of sliding grooves drilled on both sides of the notch, and the lid is characterized by having a pair of projections that can slide within the sliding grooves of the rotating body. [Effects of the Invention]

[0009] By adopting the above configuration, the dispensing container of the present invention allows users to first lower and open the lid that closes the opening of the cylindrical body by simply holding the case body and rotating the rotating body during use, and then dispense the contents through the inner tray to any length from the opening. Furthermore, after use, by rotating the rotating body in the opposite direction to how it was used, the lid is first returned to its raised position, the contents are then fed in through the inner tray, and finally, the lid is closed by hand to seal the opening.

[Modes for carrying out the invention]

[0011] Next, the dispensing container of the present invention will be described with reference to the drawings, using an example. In the following explanation, as seen in Figure 1(b), the upward direction is referred to as "up," the downward direction as "down," the vertical direction as "axis direction," the left direction as "front side," and the right direction as "back side."

[0012] In Figure 1, A is a cylindrical case body, B is a rotating body rotatably mounted on the top of case body A, C is a cylindrical body rotatably mounted on the inner circumference of case body A, D is a shaft erected from the center of the bottom of case body A, E is a middle plate whose outer circumference is non-rotatable and vertically movable mounted on cylindrical body C, and whose inner circumference is screwed into the outer circumference of shaft D, and F is a lid that is mounted to move up and down along the axial direction of rotating body B and opens and closes the top of cylindrical body C.

[0013] As shown in Figure 1(b), the case body A is connected to a cylindrical outer wall 1 and a bottom wall 2 which is formed at a predetermined height above the lower end of the outer wall 1 and has a locking ring 3 with an inner end that is inclined upward. A reduced diameter portion 4 is formed on the upper outer circumference of the outer wall 1, and a retaining projection 5 is formed on the outer circumference of the reduced diameter portion 4 so that the lower part of the rotating body B can be rotatably attached.

[0014] As shown in Figures 1(b) and 1(c), the rotating body B comprises a cylindrical outer wall 10 having the same inner and outer diameters as the outer peripheral wall 1 of the case body A, an enlarged diameter recess 11 in which the lower inner circumference of the outer wall 10 is enlarged and a retaining projection 12 that engages with the retaining projection 5 of the case body A is formed, a notch 13 cut out along the axial direction from the upper end of the back side of the outer wall 10 and into which the lifting and lowering portion F3 of the lid F (described later) slides, and a pair of sliding grooves 14 formed on both sides of the notch 13.

[0015] As shown in Figure 1(a), the upper end surface of the outer cylinder wall 10 has a low upper surface 15 formed in a range of approximately 180° on the back side, and a high upper surface 16 formed in a range of approximately 180° on the front side that is higher than the low upper surface 15, and a stepped surface 17 is formed between the low upper surface 15 and the high upper surface 16 to connect the two surfaces. As shown in Fig. 2, an undercut portion 18 for locking the cap portion F1 of the lid body F described later is formed on the stepped surface 17.

[0016] As shown in Fig. 1(b), Fig. 1(c) and Fig. 5, the cylindrical body C is formed as an inner cylindrical wall 20 whose lower end abuts on the inner surface of the bottom wall 2 of the case body A and whose upper end reaches the same height as the upper surface 16 of the rotating body B. On the inner circumference of the inner cylindrical wall 20, two guide ridges 21 that extend upward from the lower end to a predetermined height and non-rotatably guide the middle dish body E are provided opposite to each other and protrude. On the outer circumference of the cylindrical body C, a thread 22 is screwed on the upper part, and a vertical rib 23 protrudes in the axial direction below the thread 22.

[0017] The shaft body D includes a shaft support 30 and a screw shaft 31 erected from the center of the shaft support 30. A diameter-expanded portion 32 with which the locking ring 3 engages at the lower end is formed below the screw shaft 31, and a male screw 33 is screwed above the diameter-expanded portion 32.

[0018] The middle dish body E includes an outer cylinder 40 that slides up and down on the inner circumference of the inner cylindrical wall 20 of the cylindrical body C, a ring-shaped dish bottom wall 41 connected to the inner circumference of the outer cylinder 40, and an inner cylinder 42 formed at the inner edge of the dish bottom wall 41 and whose inner circumference is screwed with the screw shaft 31 of the shaft body D. It is adapted to store contents such as a rod-shaped cosmetic not shown.

[0019] On the outer circumference of the outer cylinder 40, guide concave grooves 43 that engage with the guide ridges 21 on the inner circumference of the inner cylindrical wall 20 of the cylindrical body C and prevent the middle dish body E from rotating with respect to the cylindrical body C are recessed at two opposing positions. In this embodiment, the guide ridges 21 are provided to protrude on the inner circumference of the inner cylindrical wall 20 of the cylindrical body C, and the guide concave grooves 43 are provided to be recessed on the outer cylinder 40 of the middle dish body E. However, as long as they engage with each other and can prevent the middle dish body E from rotating with respect to the cylindrical body C while being able to move up and down, guide concave grooves may be recessed on the inner circumference of the inner cylindrical wall 20 of the cylindrical body C, and guide ridges may be provided to protrude on the outer circumference of the outer cylinder 40 of the middle dish body E.

[0020] On the inner circumference of the inner cylinder 42, a female screw 44 that is screwed with the male screw 33 of the screw shaft 31 of the shaft body D is screwed.

[0021] As shown in Figures 1 and 2, the lid F consists of a cap portion F1 that closes the upper end opening of the inner cylindrical wall 20 of the cylindrical body C, and a lifting portion F3 that is connected to the cap portion F1 via a hinge portion F2.

[0022] The cap portion F1 consists of a disc-shaped top wall 50 and a semi-cylindrical side circumferential wall 51 that extends vertically from the outer edge of the top wall 50 only over a range of approximately 180° on the hinge portion F2 side, and whose outer diameter is approximately equal to the outer diameter of the outer cylinder wall 10 of the rotating body B. An undercut portion 52 is formed on the side end face 51a of the side circumferential wall 51, which engages with an undercut portion 18 formed on the stepped surface 17 of the outer cylinder wall 10 of the rotating body B.

[0023] The hinge section F2 includes a hinge 54 that rotatably (bendably) connects the cap section F1 and the lifting section F3, and a pair of elastic pieces 55 formed on both sides of the hinge 54.

[0024] The lifting section F3 includes a sliding section 57 that can slide along a notch 13 formed in the axial direction of the rotating body B, a projection 58 that protrudes from the inner circumference of the sliding section 57 and slides against the threads 22 of the cylindrical body C, and a pair of projections 59 that protrude from both sides of the sliding section 57 and slide within sliding grooves 14 drilled on both sides of the notch 13.

[0025] Next, the usage and effects of this embodiment will be described with reference to the drawings. When using the dispensing container of this embodiment, if the rotating body B is rotated relative to the case body A from the state shown in Figure 1, the sliding part 57 of the lifting part F3 housed in the notch 13 of the outer cylinder wall 10 rotates together with the rotating body B around the outer circumference of the cylinder C.

[0026] Then, the sliding portion 57 of the lifting portion F3 begins to descend as the projection 58 slides along the threads 22 of the cylindrical body C, and the protrusion 59 is guided into the sliding groove 14. As shown in Figures 3, 6(a), and 6(b), the cap portion F1 opens when the lower surface of the top wall 50 on the hinge portion F2 side is pressed against the upper end surface of the inner cylindrical wall 20 of the cylindrical body C. This releases the engagement of the undercut portion 52 of the side end surface 51a of the side peripheral wall 51, which engages with the undercut portion 18 of the stepped surface 17. The cap portion F1 then opens by rotating approximately 90° around the hinge portion F2 as a pivot point due to the action of the elastic piece 55.

[0027] Furthermore, as the rotation of the rotating body B continues, the sliding portion 57 will move as follows: as shown in Figure 6(c), the projection 59 will reach the lower end of the sliding groove 14 of the notch 13, and as shown in Figure 6(d), the projection 58 will come into contact with the vertical rib 23 of the cylindrical body C, stopping the downward movement of the sliding portion 57. If the rotating body B continues to rotate, the projection 58 of the sliding part 57 will press against the vertical rib 23 of the cylindrical body C, causing the cylindrical body C to start rotating together with the rotating body B.

[0028] When the cylindrical body C rotates, the engagement between the guide projection 21 of the cylindrical body C and the guide groove 43 of the inner dish body E causes the inner dish body E to start rotating along with the rotation of the rotating body B. At this time, since the screw shaft 31 of the shaft body D is not rotatable relative to the case body A, the rotation of the inner cylinder 42 of the inner dish body E causes the inner dish body E to rise, allowing the contents to be dispensed. As shown in Figure 4, when dispensing the contents from the upper end opening of the inner wall 20 of the cylindrical body C, the cap portion F1 is positioned along the outer circumference of the rotating body B, so it does not get in the way when dispensing and using the contents.

[0029] Next, after the contents have been used, when the rotating body B is started to rotate in the opposite direction to when the contents were used, as shown in Figure 4, the projection 58 of the sliding part 57 of the lifting part F3 will no longer come into contact with the vertical rib 23 of the cylindrical body C, as shown in Figures 7(a) and (b). As a result, the rotating body B will rotate around the outer circumference of the cylindrical body C, and the sliding part 57 housed in the notch 13 of the rotating body B will begin to rise as the projection 58 slides along the threads 22 of the cylindrical body C, with the protrusion 59 being guided into the sliding groove 14.

[0030] Furthermore, as the rotation of the rotating body B continues, the sliding portion 57 reaches the upper end of the sliding groove 14 of the notch 13, as shown in Figure 7(c), and the projection 58 comes into contact with the vicinity of the upper end of the screw thread 22 of the cylindrical body C, as shown in Figure 7(d). As a result, the upward movement of the sliding portion 57 stops, and the cap portion F1 (lid F) returns to the raised position shown in Figure 2.

[0031] As the rotating body B is rotated, the projection 58 of the sliding part 57 presses the screw threads 22 of the cylindrical body C in the direction of the arrow, causing the cylindrical body C to start rotating in the opposite direction to that during use, together with the rotating body B. When the cylindrical body C rotates, the inner dish E also starts to rotate in the opposite direction to the rotation of the rotating body B. The rotation of the inner cylinder 42 causes the inner dish E to start to descend, allowing the contents to be loaded.

[0032] As the rotating body B rotates, the inner dish E descends to the upper end of the enlarged diameter portion 32 of the shaft D, and once the loading of the contents is complete, the rotation of the rotating body B and the cylindrical body C stops. Finally, when the lid F is manually rotated using the hinge portion F2 as a pivot point, the undercut portion 52 formed on the side circumferential wall 51 of the cap portion F1 engages with the undercut portion 18 formed on the stepped surface 17 of the rotating body B, thereby closing the opening of the cylindrical body C.

[0033] Next, when using the contents again, rotate the rotating body B from the state shown in Figures 7(c) and (d), and rotate the sliding part 57 of the lifting part F3 in the opposite direction to the arrow. The projection 58 of the sliding part 57 will temporarily detach from the screw threads 22 of the cylindrical body C and rotate once around the outer circumference of the cylindrical body C, returning the projection 58 of the sliding part 57 to the position shown in Figure 6(b), and returning to the state shown in Figures 1 and 2.

[0034] In this embodiment, when using the contents of the dispensing container, the rotating body B is rotated relative to the cylindrical body C, causing the lid F to descend and open the cap portion F1 that closes the opening of the cylindrical body C. After the lid F has descended to the standby position, the rotating body B is rotated integrally with the cylindrical body C, allowing the contents to be dispensed via the inner tray E. Furthermore, after using the contents, the lid F is returned to its raised position by rotating the rotating body B in the opposite direction to the direction used during use relative to the cylindrical body C. Then, by rotating the rotating body B together with the cylindrical body C, the contents are fed in through the inner tray E, and finally, the cap F1 can be closed with the fingers. [Industrial applicability]

[0035] The dispensing container of the present invention can be used in a convenient manner as an improved dispensing container. When in use, simply by holding the case body and rotating the rotating body, the lid that closes the opening of the cylindrical body is opened first, and then the contents are dispensed from the opening to any length via the inner tray.
