Problems to be Solved by the Invention

[0004] By the way, in recent years, there are many makeup removers that can be used during bathing on the market. Also, the proportion of consumers who take only showers for bathing is increasing, and there is a desire to hang the above-mentioned makeup removers, shampoos, conditioners, etc. on a towel rack in the bathroom and store them within reach.

[0005] Therefore, the present invention aims to provide a dispenser with a stopper that prevents unintended downward pressing of the pressing head, and that also has a configuration that restricts the pressing of the pressing head, as well as a configuration that allows it to be suspended from a towel rack or the like. [Means for solving the problem]

[0006] The stopper-equipped dispenser of the present invention, developed to achieve the above objective, comprises a cap attached to the neck of a container to seal and maintain the contents of the container, a pressing head fixedly held by the cap and used to dispense the contents of the container through a nozzle by repeatedly pressing it, and a stopper that restricts the pressing of the pressing head, The stopper comprises a base rotatably mounted on the top surface of the cap, a stopper body rising from the upper surface of the base and surrounding at least the lower nozzle area of ​​the pressing head, and a cover provided on the stopper body and having an upper member positioned at least above the nozzle and covering the nozzle. The stopper body has a pressing restricting piece that engages with the lower end of the pressing head to prevent the pressing head from being pushed in when the nozzle is covered by the cover, while the base rotates around the pressing head together with the stopper body and cover, and the engagement is released when the nozzle is exposed from the cover, allowing the pressing head to be pushed in. The cover is characterized by having a support portion that allows the container to be suspended together with the dispenser.

[0007] Furthermore, in the stopper-equipped dispenser of the present invention, when the push-in restricting piece is located below the notch formed in the peripheral wall of the press head, it allows the press head to be pushed in, Notch It is preferable that it is positioned by contacting the end face.

[0008] Furthermore, in the stopper-equipped dispenser of the present invention, the support portion is preferably hook-shaped.

[0009] Furthermore, in the stopper-equipped discharger of the present invention, it is preferable that the cover has a lower member that covers the area below the nozzle, or a side member that is connected to the lower member and the upper member and covers only one side of the nozzle.

[0010] Furthermore, in the stopper-equipped dispenser of the present invention, it is preferable that the support portion is provided protruding from the tip of the cover. [Effects of the Invention]

[0011] According to the stopper-equipped dispenser of the present invention, the base, which is rotatably mounted on the top surface of the cap, can be rotated together with the stopper body and cover around the pressing head, thereby easily switching the pressing head between a locked state (press-down restricted state) and an unlocked state (press-down enabled state).

[0012] Furthermore, with the stopper-equipped dispenser of the present invention, at least the upper part of the nozzle can be protected by the cover (upper surface member) during the distribution or storage of the container, and the downward movement of the pressing head can be prevented by engaging the pressing restricting piece provided on the inner wall surface of the stopper body with the lower end of the pressing head, thereby effectively preventing damage to the nozzle and unintended leakage of the contents.

[0013] Furthermore, according to the stopper-equipped dispenser of the present invention, a notch is provided in the pressing head, and when using the container (when the pressing head is unlocked), the stopper body is rotated to move the push-in restricting piece provided in the stopper body into the notch, thereby allowing the pressing head to be pushed in. In addition, the range of rotation of the stopper body is restricted by the push-in restricting piece contacting the end of the notch, and the pressing head can be switched between a locked state and an unlocked state at a desired position.

[0014] Furthermore, according to the stopper-equipped dispenser of the present invention, by providing a support portion preferably at the tip of the cover, the container can be suspended from a rod-shaped member such as a towel rack via the support portion for storage.

FIG. 4 is a diagram showing the form of the dispenser with a stopper according to the present invention during the use of the container, where (a) is a plan view, (b) is a front view, and (c) is a view showing the F-F end face of FIG. 4(b).

[0017] In FIGS. 1 to 4, reference numeral 1 denotes a container for containing contents (the lower part of the container is omitted), and 2 denotes a cap that is screwed onto the neck portion of the container 1 to hermetically hold the inside of the container 1. Also, in FIGS. 1 to 4, reference numeral 3 denotes a pressing head, and 4 denotes a nozzle provided on the pressing head 3.

[0018] The container 1 can be manufactured by extrusion blow molding or biaxial stretch blow molding using a material such as synthetic resin, but the material of the material is not particularly limited. Further, in the present embodiment, a cylindrical container 1 is shown as an example, but the shape of the container can be appropriately changed based on the type of contents, the design of the container, the use, etc., and is not limited to the illustrated shape.

[0019] The cap 2 is detachably attached by screwing or undercut fitting to the neck portion of the container 1. The cap 2 can be manufactured using a material such as synthetic resin, but the material of the material is not particularly limited. Further, in the present embodiment, a cylindrical one is shown as an example, but it is not limited to the illustrated shape.

[0020] On the back surface of the cap 2, a dispenser (such as a pump) that is suspended and held at the neck portion of the container 1 and to which the pressing head 3 is assembled is disposed (not shown). By repeatedly pushing in the pressing head 3, the contents contained in the container 1 are sucked, pressurized, compressed, and discharged from the nozzle 4 of the pressing head 3.

[0021] Furthermore, in Figures 1-4, reference numeral 5 denotes a recess provided along the circumferential direction at the lower end of the peripheral wall of the pressing head 3, 6 denotes a notch provided in the peripheral wall of the pressing head 3, 7 denotes a disc-shaped base that is rotatably fitted and held to the top surface of the cap 2 via an undercut, 8 denotes a stopper body consisting of an annular body that rises from the upper surface of the base 7 and surrounds at least the lower region of the nozzle 4 of the pressing head 3, and 9 denotes a cover provided on the stopper body 8 that covers only one side of the nozzle 4, either above, below, or to the side.

[0022] In Figures 1-4, reference numeral 10 denotes a pressing restricting piece that protrudes from the inner wall of the stopper body 8 and prevents the pressing head 3 from being pressed in, and reference numeral 11 denotes a rib that is provided on the outer peripheral wall of a cylindrical body 13 connected to the lower surface of the pressing head 3 and engages with a recess 14 provided on the inner peripheral wall of the pressing head 3 to restrict the rotation of the pressing head 3.

[0023] The push-in restricting piece 10 can be composed of at least two vertical ribs 10a that stand upright along the inner wall of the stopper body 8, and a horizontal rib 10b that spans the upper end of the vertical ribs 10a.

[0024] The stopper basically consists of a base 7, a stopper body 8, a cover 9, and a push-in restricting piece 10. The stopper is made of synthetic resin, but the material is not particularly limited. In this embodiment, the base 7, stopper body 8, cover 9, and push-in restricting piece 10 are molded as a single unit, but they may be made as separate parts.

[0025] The recess 5 is formed in a range of approximately 90° in the circumferential direction from one side end 6a of the notch 6. In the recess 5, as shown in Figures 1 and 2, when the nozzle 4 is covered by the cover 9 (when the pressing head 3 is locked), the push-in restricting piece 10 of the stopper body 3 is positioned in the recess 5 and engages with the lower end of the pressing head 3, as shown in the exploded view of Figure 3(b). Therefore, in this state, even if the pressing head 3 is pushed downward to discharge the contents, the push-in restricting piece 10 prevents the pressing head 3 from being pushed in, and the contents are not discharged.

[0026] Furthermore, the notch 6 is located on the lower part of the peripheral wall of the pressing head 3, at a position approximately 90° away from the nozzle 4 in the circumferential direction. As a result, when the base 7 is rotated 90° together with the stopper body 8 and cover 9, as shown in Figures 4(a) and (b), the nozzle 4 is exposed from the cover 9, and the push-in restricting piece 10 is positioned below the notch 6, as shown in the exploded view of Figure 4. This releases the engagement of the push-in restricting piece 10 at the lower end of the pressing head 3, allowing the pressing head 3 to be pushed in and the contents to be discharged. The notch 6 may also be formed by creating a recess.

[0027] In this embodiment, the base 7 is configured to be rotated 90° to switch the pressing head 3 between a locked state and an unlocked state. However, the embodiment is not limited to this configuration, and the switching angle between the locked and unlocked states of the pressing head 3 can be appropriately changed by changing the positions of the recess 5 and the notch 6.

[0028] Furthermore, as described above, the push-in restricting piece 10 moves within the recess 5 as the base 7 rotates, and one end 10c of the push-in restricting piece 10 abuts against the end 5a of the recess 5, and the other end 10d abuts against the other side end 6b of the notch 6. This sets the rotation range of the base 7, and allows for precise positioning of the engagement position and release position (notch 6 position) of the lower end of the pressing head 3 and the push-in restricting piece 10.

[0029] In this embodiment, the cover 9 consists of an upper member 9a, a lower member 9b, and a side member 9c. However, the cover 9 may cover only the top of the nozzle 4, or both the top and bottom, and is not limited to this aspect.

[0030] Furthermore, the tip of the cover 9 has a support portion 12 that protrudes from it, and as shown in Figure 5, the container 1 can be suspended from a rod-shaped member 15 such as a towel rack using the support portion 12 together with the dispenser including the pressing head 3. Note that the support portion 12 may have any shape other than the hook shape of this embodiment, as long as it can be suspended from the rod-shaped member 15. [Industrial applicability]

[0031] The stopper-equipped dispenser of the present invention can be suitably used as a container for filling liquid, creamy, viscous foods and beverages, cosmetics, pharmaceuticals, detergents, and the like. [Explanation of symbols]
