In this embodiment, "upper" may refer to the side of the mouth 13 of the container body 10. In this embodiment, "lower" may refer to the side of the bottom (not shown) of the container body 10. In this embodiment, the circumferential direction refers to the direction that goes around the container central axis O. Furthermore, the radial direction refers to the direction perpendicular to the container central axis O.

In FIG. 1, reference numeral 1 denotes a dispensing container according to one embodiment of the present invention. Dispensing container 1 is used, for example, as an application container for applying contents M to the scalp of a human body.

Referring to FIG. 1, the dispensing container 1 has a container body 10, an inner plug 2, a dispensing plug 3, a movable claw member 4, and a cover member 5. In this embodiment, the dispensing container 1 is covered with an overcap 6.

The container body 10 is a container capable of containing the contents M. In this embodiment, the container body 10 has a body 11 with a closed bottom (not shown), and a mouth 13 connected to the body 11 via a shoulder 12. A storage space S10 capable of containing the contents M is formed inside the container body 10. The mouth 13 has an opening A10 that connects the storage space S10 to the outside. The container body 10 can be made of a synthetic resin such as polypropylene (PP). The overcap 6 is removably screwed to the mouth 13. The overcap 6 can also be made of a synthetic resin such as polypropylene (PP). According to the present invention, the overcap 6 can be removably attached to the mouth 13 by press-fitting or concave-convex fitting.

The inner plug 2 closes the opening A10 formed in the mouth 13 of the container body 10 and has a flow port A2 through which the contents M can flow.

Figure 2 shows the dispenser container 1 with the overcap 6 removed.

The dispensing plug 3 has a storage dome 3a capable of storing the contents M, and a dispensing tube 3b connected to the storage dome 3a. A storage chamber S3 is formed inside the storage dome 3a. The storage chamber S3 can store the contents M introduced through the flow port A2 of the inner plug 2. A dispensing path R3 leading to the storage chamber S3 is formed inside the dispensing tube 3b. The dispensing path R3 is connected to the outside world through the dispensing outlet A3 formed at the upper end of the dispensing tube 3b. This allows the contents M in the storage chamber S3 to be poured out to the outside world through the dispensing outlet A3. The dispensing plug 3 can be formed of an elastic synthetic resin, such as low-density polyethylene (LDPE). In this case, even when the inner diameter of the dispensing outlet A3 is set so as not to allow the contents M to be poured out when the dispensing container 1 is inverted or tilted, the contents M can be poured out by pressing the storage dome 3a. In this embodiment, an outward flange 3c is formed on the underside of the storage dome 3a.

The movable claw member 4 has multiple elastic pieces 4a that extend in a spiral shape so as to wrap around the spout faucet 3, and multiple claws 4b that are connected to the tips of the multiple elastic pieces 4a.

As described below, when the comb-shaped tube portion 5b of the cover member 5 is pressed into the cover dome 5a, the cover member 5 comes into contact with the elastic piece 4a, which can push the claws 4b outward. In addition, when the comb-shaped tube portion 5b of the cover member 5 is further pressed in, the elastic piece 4a presses against the storage dome 3a.

In addition, in this embodiment, the elastic piece 4a has a protrusion 4g that presses against the storage dome 3a.

In this embodiment, the movable claw member 4 has a fixed portion 4f that is fixed to the mouth 13 of the container body 10 so as to sandwich the inside plug 2 and the dispensing plug 3. The fixed portion 4f has a fixed tube 4f1 that is fixed to the mouth 13, and a partition wall 4f2 that is formed in an annular shape inside the fixed tube 4f1. By being fixed to the mouth 13, the fixed portion 4f sandwiches the top wall 2a of the inside plug 2 and the outward flange 3c of the dispensing plug 3 between the partition wall 4f2 and the mouth 13. The elastic piece 4a extends in a spiral shape from the fixed portion 4f so as to wrap around the dispensing plug 3. In this embodiment, the elastic piece 4a extends in a spiral shape from the inner edge of the partition wall 4f2 toward the upper side so as to wrap around the dispensing plug 3. The claws 4b are connected to each tip of the elastic piece 4a so as to stand along the dispensing tube 3b and are arranged at intervals around the dispensing tube 3b. The movable claw member 4 can also be made of a synthetic resin such as polypropylene (PP).

In this embodiment, the elastic piece 4a has a base 4a1 that surrounds the storage dome 3a of the spout tap 3, a first arm 4a2 that is connected to the base 4a1, and a second arm 4a3 that is connected to the first arm 4a2. The first arm 4a2 and the second arm 4a3 are bent relative to the base 4a1 so as to wrap around the storage dome 3a and the spout tube 3b of the spout tap 3. In this embodiment, the first arm 4a2 is bent relative to the base 4a1 so as to wrap around the spout tube 3b of the spout tap 3. The second arm 4a3 is bent horizontally relative to the first arm 4a2 so as to wrap around the spout tube 3b of the spout tap 3. The claw 4b is connected to the second arm so as to stand along the spout tube 3b.

In addition, in this embodiment, the protrusion 4g is positioned on the inside of the bend between the base 4a1 and the first arm 4a2 of the elastic piece 4a.

Figure 3 is a plan view showing the dispensing container 1 from above.

Referring to FIG. 3, the multiple claws 4b are arranged on the same circumference in a plan view. In this embodiment, the multiple claws 4b are arranged on an imaginary circle CL centered on the central axis O of the container. In this embodiment, the dispensing container 1 has three elastic pieces 4a. That is, in this embodiment, the dispensing container 1 has three claws 4b. Although it is preferable that there are three claws 4b (elastic pieces 4a), according to the present invention, it is sufficient that there are multiple claws 4b (elastic pieces 4a).

In this embodiment, the claw 4b is a plate arranged to face the dispensing tube 3b in a plan view as shown in FIG. 3. FIG. 4 shows a partial cross section of the dispensing container 1 as seen from the direction of the arrow D in FIG. 3. Referring to FIG. 4, the claw 4b has a shape that tapers toward the tip. The tip (upper end) of the claw 4b is rounded with a radius r.

The cover member 5 has a cover dome 5a that covers the multiple elastic pieces 4a, and a comb-shaped tube portion 5b that is connected to the cover dome 5a so as to surround the multiple claws 4b. The cover member 5 is an elastically deformable cover member. The cover member 5 can be formed, for example, from an elastic synthetic resin such as an elastomer.

In this embodiment, the cover dome 5a is fixed to the fixed portion 4f of the movable claw member 4. In this embodiment, the lower end 5a1 of the cover dome 5a is fixed to the inside of the fixed tube 4f1. In this embodiment, the cover member 5 has an outer flange 5d. The outer flange 5d protrudes radially outward from the outer surface of the cover dome 5a. The upper end of the fixed tube 4f1 is sealed by the outer flange 5d. The comb-shaped tube portion 5b has a plurality of comb-shaped protrusions 5c arranged at intervals in the circumferential direction at the upper end. As shown in FIG. 4, in this embodiment, the tip (upper end) of the comb-shaped protrusions 5c protrudes upward by a length ΔL from the tip (upper end) of the claw 4b. Referring to FIG. 3, the comb-shaped tube portion 5b has four comb-shaped protrusions 5c. The four comb-shaped protrusions 5c are arranged at equal intervals (90 degrees) in the circumferential direction. It is preferable that the number of comb-shaped protrusions 5c is also four, but according to the present invention, the number of comb-shaped protrusions 5c may be more than one.

Next, an example of how to use the dispensing container 1 will be described. In the following description, the part to be applied (hereinafter also referred to as the "application part") 100 is the scalp of a human body. The content M is a drug (e.g., a hair growth agent) to be applied to the scalp of a human body.

As shown in FIG. 1, the dispensing container 1 is covered with an overcap 6 when not in use. The overcap 6 is removed when in use, as shown in FIG. 2.

When in use, the dispensing container 1 is inverted as shown in FIG. 5. This allows the contents M contained in the storage space S10 of the container body 10 to pass through the flow port A2 of the inner plug 2 and enter the storage chamber S3 of the dispensing plug 3. In this embodiment, the inner diameter of the comb-shaped tube portion 5b (the diameter of the dispensing path R) is small. Therefore, the contents M will not be dispensed from the dispensing path R simply by inverting the dispensing container 1.

Next, as shown by the arrow in Figure 5, in order to apply the contents M to the application part (scalp) 100, the comb-shaped tube portion 5b of the cover member 5 is pressed against the application part 100. At this time, since the comb-shaped tube portion 5b protrudes beyond the claws 4b, the comb-shaped tube portion 5b first comes into contact with the hair 101 and pushes the elastic piece 4a of the movable claw member 4 toward the central axis O of the container. As a result, the claws 4b are pushed outward in the radial direction, and the claws 4b push aside the hair 101 while allowing the dispensing tube 3b of the dispensing tap 3 to reach the application part 100. In detail, when the comb-shaped tube portion 5b is pressed against the application part 100, the comb-shaped tube portion 5b is pushed into the cover dome 5a as shown in Figure 6. At this time, the lower end 5b2 of the comb-shaped tube portion 5b of the cover member 5 (the connection portion between the comb-shaped tube portion 5b and the cover dome 5a) pushes the elastic piece 4a of the movable claw member 4 down toward the central axis O of the container. As a result, the claws 4b connected to the elastic piece 4a are pushed outward in the radial direction as shown by the arrow D1. At this time, the claws 4b push aside the hair (head hair) 101 around the applicator portion 100. As a result, the dispensing tube 3b of the dispensing tap 3 pushes aside the hair 101 to reach the applicator portion 100.

Then, by pushing the comb-shaped tube portion 5b of the cover member 5 further into the cover dome 5a, the elastic piece 4a of the movable claw member 4 presses against the storage dome 3a of the dispensing tap 3. This allows the contents M to be dispensed from the dispensing outlet A3 directly into the applicator part 100 while avoiding the bristles 101.

According to the dispensing container 1, when the comb-shaped tube portion 5b of the cover member 5 is pushed into the cover dome 5a, the elastic piece 4a of the movable claw member 4 can push the claws 4b outward by the cover member 5 coming into contact with the elastic piece 4a. This allows the bristles 101 to be pushed away from the application portion 100. Then, by further pushing the comb-shaped tube portion 5b, the elastic piece 4a can press the storage dome 3a of the dispensing tap 3. When the elastic piece 4a presses the storage dome 3a of the dispensing tap 3, the storage dome 3a deforms in a direction that reduces the storage chamber S3. This allows the contents M to be dispensed through the dispensing tube 3b of the dispensing tap 3. In this way, according to the dispensing container 1, the bristles 101 are pushed aside to expose the application portion 100, and then the contents M can be directly applied to the application portion 100. Therefore, according to the dispensing container 1, the contents M can be directly applied to the area where the hair grows.

In particular, in this embodiment, the elastic piece 4a has a protrusion 4g for pressing against the storage dome 3a. In this case, the elastic piece 4a can efficiently press against the storage dome 3a. Therefore, in this case, the contents M can be efficiently applied to the application part 100.

In addition, in this embodiment, the first arm 4a2 and the second arm 4a3 of the elastic piece 4a are bent relative to the base 4a1 so as to wrap around the storage dome 3a and the dispensing tube 3b, and the claw 4b is connected to the second arm 4a3 so as to stand up along the dispensing tube 3b. In this case, the elastic piece 4a can be easily elastically deformed. Also, in this case, the geometric shape of the elastic piece 4a allows the claw 4b to be efficiently made large and wide.

In addition, in this embodiment, the multiple claws 4b are arranged on the same imaginary circle CL in a plan view as shown in FIG. 3. In this case, the multiple claws 4b evenly push aside the bristles 101 around the central axis O of the container. Therefore, the contents M are evenly dispensed onto the applicator 100 around the central axis O of the container.

In this embodiment, the claw 4b is a plate that is arranged to face the dispensing tube 3b in a plan view as shown in FIG. 3. Also, referring to FIG. 4, the claw 4b is tapered toward the tip, and the tip of the claw 4b is rounded. In this case, the hair 101 can be gently pushed aside.

The dispensing container 1 according to this embodiment further includes an inner plug 2 that closes the opening A10 formed in the mouth portion 13 of the container body 10 and has a flow port A2 formed therein through which the contents M can flow. In this case, the flow port A2 functions as an orifice hole, so that the contents M can be dispensed quantitatively.

The present invention provides a dispensing container 1 that allows the contents to be applied directly to areas with hair.

The above describes an exemplary embodiment of the present invention, and various modifications can be made without departing from the scope of the claims. For example, the overcap 6 may be included in the dispensing container 1. The contents M are not particularly limited. Examples of the contents M include liquids such as hair growth agents, medicines, and cosmetics that are applied to the scalp, skin, etc. of the human body. Furthermore, the contents M are not limited to those for the human body, and may be contents that are applied to something other than the human body. Furthermore, the contents M are not limited to liquids, and may be, for example, powder-like contents such as granules and powder.
