[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows one embodiment of a propelling container according to the present invention, with (a) being a plan view, (b) being a front view, and (c) being a bottom view. Fig. 2(a) is a plan view of the propelling container of Fig. 1 with the cover cap removed, (b) being a cross-section taken along line AA in Fig. 1, and (c) being a bottom view. Fig. 3(a) is a cross-section taken along line BB of the propelling container of Fig. 2, and (b) is a cross-section taken along line CC. Note that although all of the components of the propelling container according to the present invention can be made of synthetic resin, all or part of them may also be made of metal.

[0015] 1 to 3, reference numeral 1 denotes a feeding container, which is composed of a screw rod 10, an inner plate 20, a case body 30, and a cover cap 40. The axes of the screw rod 10, the inner plate 20, the case body 30, and the cover cap 40 are located on a common axis. Hereinafter, this common axis will be referred to as the container axis L, and the side of the overcap 40 along the container axis L will be referred to as the upper side, and the opposite side will be referred to as the lower side.

[0016] The screw rod 10 consists of a base 11 for holding the screw rod 10 in an upright position and a rod body 12 having a threaded portion 12c formed on the peripheral wall, and the base 11 and the rod body 12 are molded integrally.

[0017] The base 11 has a bottom wall 14 with an opening 14b in the center that forms a filling port for the contents M, a cylindrical operating part 14a hanging down from the outer periphery of the bottom wall 14, and a flange 15 extending radially outward at the upper end. The base 11 is rotatable around the container axis L via the operating part 14a, and the outer periphery of the operating part 14a is provided with a plurality of grooves 14c as shown in Fig. 1 to prevent slipping when the base 11 is gripped and rotated with fingers. In addition, a step 14d is provided on the upper surface of the bottom wall 14 for placing the lower end of a case main body 30 (described later).

[0018] The rod body 12 is connected to a flange portion 15 of the base 11, and is configured so that a middle plate 20 (described later) can be raised and lowered along the rod body 12 via a threaded portion 12c provided on the peripheral wall. The rod body 12 comprises a cylindrical lower body portion 12a having an internal passage 13 therein, and an upper body portion 12b whose interior is divided into four spaces 17 by cross-shaped partition portions 16. The partition portions 16 are not limited to a cross shape and can have various shapes. By configuring the upper body portion 12b with the partition portions 16, the amount of material used in the rod body 12 can be reduced, and the weight can be reduced.

[0019] The lower body portion 12a of the rod body 12 has one or more window holes 19 in its peripheral wall that communicate with the internal passage 13. When the contents M are poured through the opening 14b formed in the bottom wall portion 14 of the base 11, the contents M pass through the internal passage 13 to fill the space 17 in the upper body portion 12b, and also pass through the window holes 19 to fill the filling space S in the case body 30, which will be described later. The window holes 19 may be of various shapes, such as rectangular or round. Alternatively, a filling nozzle may be inserted into the interior through the opening 14b, and the contents M may be filled from the portion close to the window holes 19. In this case, the contents M remain only at the upper end of the internal passage 13, thereby reducing the remaining amount.

[0020] In addition, if the lower body part 12a of the rod body 12 is a cylindrical body with an open upper end and the cross-shaped partition part 16 of the upper body part 12b is integrally connected to the upper end, the contents M can be filled into the space 17 and the filling space S from the open part at the upper end of the lower body part 12a, so there is no need to provide a window hole 19. Furthermore, a top wall may be provided at the upper end of the lower body portion 12a to close the upper end portion, so that the internal passage 13 of the lower body portion 12a and the space 17 of the upper body portion 12b do not directly communicate with each other.

[0021] The upper body portion 12b of the rod body 12 has a reduced diameter portion 12b1 at its upper end, which is smaller than the threading diameter of the inner plate 20 (described later) (the diameter of the threads of the threaded portion 21a formed on the inner peripheral surface of the inner cylinder 21) and has no threaded portion 12c on its outer peripheral surface. Therefore, the reduced diameter portion 12b1 serves as the upper limit position of the inner plate 20 (described later) that screws into the threaded portion 12c, preventing interference with the threads of the threaded portion 21c of the inner plate 20. Furthermore, providing the reduced diameter portion 12b1 has the advantage that the inner plate 20 can be easily fitted onto the screw rod 10 from above when assembling the dispensing container 1.

[0022] A comb-shaped member 18 is provided integrally with the screw rod 10 at the top of the upper main body portion 12b. Although the comb-shaped member 18 has seven rod-shaped comb teeth in FIG. 2, the shape and number of the comb teeth are not particularly limited. In this embodiment, the comb-shaped member 18 is provided at the top of the upper main body portion 12b of the screw rod 10, but the comb member 18 may also be provided at the upper end of the case main body 30 (described later), or at both.

[0023] The inner plate 20 is composed of an inner cylinder 21 having a threaded portion 21a formed thereon to engage with the threaded portion 12c of the screw rod 10, an outer cylinder 22 that slidably contacts the inner wall of the case body 30 (described later), and a connecting portion 23 that integrally connects the inner cylinder 21 and the outer cylinder 22 to each other. The outer cylinder 22 has at least one vertical groove 22a (two in the figure) on its outer peripheral wall.

[0024] The case body 30 surrounds the inner plate 20 together with the screw rod 10, forming a filling space S for the contents M inside, with an open end 32 at its upper part serving as an extrusion port for the contents M. The case body 30 is a cylindrical body with open top and bottom, and its inner peripheral wall is formed with vertical ribs 30a that fit into the vertical grooves 22a formed in the outer tube 22 of the inner plate 20. The vertical ribs 30a engage with the vertical grooves 22a of the inner plate 20, thereby restricting rotation of the inner plate 20 around the container axis L. Alternatively, vertical ribs may be formed on the outer tube 22 of the inner plate 20, and vertical grooves that engage with the vertical ribs may be formed on the inner peripheral wall of the case body 30.

[0025] The inner plate 20, whose rotation around the container axis L is restricted, rises and falls in accordance with the rotation of the screw rod 10 via the base 11, thereby allowing it to slide appropriately within the case body 30 between the lowest position shown in Figure 2 and the upper limit position shown by the dashed line in the figure.

[0026] The case body 30 has a diameter substantially equal to that of the bottom wall 14 of the base 11, and its lower end is fitted into the step 14d of the bottom wall 14. On the other hand, a tongue 31 is provided which protrudes from the inner wall of the lower end of the case body 30 toward the container axis L and engages with the underside of the flange 15 of the screw rod 10. The tongue 31 holds the case body 30 rotatably relative to the screw rod 10 so as not to come off.

[0027] The case body 30 has an opening 33 at its upper end, the outer diameter of which is smaller than that of the main body, and a cover cap 40 (described later) is provided to cover the opening 33. The outer circumferential surface of the opening 33 is provided with an annular rib 33a that can be engaged with the cover cap 40.

[0028] In addition, the lower end surface 30b of the case body 30 is cut out in an arc shape. By making it arc-shaped, the contact area between the lower end surface 30b of the case body 30 and the upper surface of the bottom wall portion 14 of the screw rod 10 can be reduced, and the operating portion 14a can be rotated smoothly.

[0029] The cover cap 40 is a cap that seals the open end 32 of the case body 30, and is composed of a top wall 42 having a protrusion 41 in the center for accommodating the comb-shaped member 18, an inner cylinder 43 hanging down from the protrusion 41, and an outer cylinder 44 hanging down from the outer edge of the top wall 42, and is detachably held in place by fitting a rib 44a on the inner peripheral surface of the outer cylinder 44 with a rib 33a on the outer peripheral wall of the mouth 33 of the case body 30 by an undercut or the like. Note that threads may be provided on the inner peripheral wall of the outer cylinder 44 and the outer peripheral wall of the mouth 33, respectively, to threadably engage the cover cap 40 and the case body 30.

[0030] The cover cap 40 can cooperate with the outer tube 44 to seal the open end 32 of the case body 30 by abutting (fitting) the inner wall of the inner tube 43 against the reduced diameter portion 12b1 of the screw rod 10, thereby preventing leakage of the contents M from the open end 32 when filling the contents M and protecting the comb-shaped member 18 when filling the contents M.

[0031] In the dispensing container 1 having the above-described configuration, the contents M are not particularly limited, and can be any substance that can be dispensed from the case body 30 and applied while combing with the comb-shaped member 18, and can be used, for example, as hair cosmetics or medicines, or animal medicines.

[0032] In addition, the contents M can be liquid or viscous, and can be filled into the space 17 of the rod body 12 through the internal passage 13 from the opening 14b provided in the bottom wall portion 14 of the screw rod 10, and into the filling space S in the case body 30 through the window hole 19, with the cover cap 40 attached to the case body 30 and the open end 32 of the case body 30 sealed, and then solidified for use.

[0033] FIG. 4 is a diagram showing the propelling container 1 according to the present invention in use. At the start of use, the case body 30 is grasped and fixed with the fingers, and the base 11 of the screw rod 10 is rotated around the container axis L as described above. Then, the threaded portion 21a of the inner tube 21 of the inner plate 20 engages with the threaded portion 12c of the rod body 12, causing the inner plate 20 to screw up, and this screwing force separates the contents M filled and solidified in the filling space S of the case body 3 from the contents M in the space 17 of the main body upper part 12b (the contents M in the space 17 are restricted in their upward movement by the disc-shaped partition wall provided between the comb-shaped member 18 and the main body upper part 12b of the rod body 12), causing them to rise cylindrically.

[0034] The cylindrical contents M are dispensed to a position where they do not protrude from the tip of the comb-shaped member 18. For example, in the case of a hair styling product, as shown in Figure 4, the dispenser 1 is tilted downward, the comb-shaped member 18 is pressed against the scalp, and the contents M is applied while combing the hair, so that the contents M does not come into direct contact with the scalp and the contents M can be easily applied not only to the surface of the hair but also to the inside of the hair. [Industrial Applicability]

[0035] The propelling container of the present invention can be widely used as a container for hair styling products, medicines, etc. [Explanation of symbols]
