Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, many makeup removers that can be used during bathing have been circulating in 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 remover, shampoo, conditioner, 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 for a dispensing device equipped with a pressing head, 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 is provided on the cap or a base fitted and held by the cap, and is rotatable via a hinge, and rotates around the hinge to be placed in an upright position, thereby detachably fitting to the back of the pressing head, and rotates around the hinge to be placed in an inclined position, thereby positioning on the peripheral wall side of the cap or the base, and has a pair of arms connected to the holder body, which are positioned on both sides of the pressing head when the holder body is in an upright position. The holder body has, when the holder body is in an upright position, a projection on the side facing the pressing head that detachably fits onto the lower edge of the pressing head, and when the holder body is in an upside-down position, a locking claw that detachably connects to the cap or the base to maintain the upside-down position of the holder body. The pair of arms are characterized in that, when the holder body is in an inverted position and the locking claws are linked to the cap or the base, they form a space for inserting the hanger between the shoulder portion of the container and the arms, thereby constituting a suspension support portion that suspends the container together with the pressing head.

[0007] Furthermore, in the stopper-equipped dispenser of the present invention, it is preferable that the pair of arms are fixed to and extended across the tip, and that when the holder body is in an upright position and the pair of arms are positioned on both sides of the pressing head, there is a pressing restriction plate that covers the upper surface of the pressing head and prevents the pressing head from being pushed in.

[0008] Furthermore, in the stopper-equipped dispenser of the present invention, it is preferable that the hinge, the locking claw, and the suspension support portion are formed at the same position in the radial or circumferential direction of the container. [Effects of the Invention]

[0009] According to the stopper-equipped dispenser of the present invention, the pressing head can be easily switched between a locked state (downward pressing restricted state) and an unlocked state (downward pressing possible state) by rotating the holder body via a hinge to move it between an upright position and a tilted position.

[0010] Furthermore, with the stopper-equipped dispenser of the present invention, when the holder body is held in an upright position, the protrusion provided on the side facing the pressing head fits onto the lower end of the pressing head, thereby preventing the pressing head from moving downward, and thus effectively preventing unintended leakage of the contents.

[0011] Furthermore, according to the stopper-equipped dispenser of the present invention, the holder body is provided with a locking claw that detachably engages with a cap provided on the neck of the container or a base fitted and held by the cap when the holder body is in an inverted position (locked state). This allows the holder body to remain in an inverted position, and the stopper does not get in the way during use.

[0012] Furthermore, in the linked state of the locking claws, a hanging support section consisting of a space for inserting a hanger is formed between the pair of arm sections constituting the stopper and the shoulder section of the container, and the container can be hung from a towel rack or the like via this hanging support section for use.

[0013] Furthermore, with the stopper-equipped dispenser of the present invention, when the holder body is in an upright position (locked state), the upper surface of the pressing head is covered by a pressing restriction plate fixed to and extended across the tips of a pair of arms, so there is no risk of the pressing head being pressed in during distribution or storage. [Brief explanation of the drawing]

[Figure 2] Figure 1 shows one embodiment of the stopper-equipped dispenser when the holder body is in an inverted position (unlocked state), where (a) is a plan view and (b) is a side view of (a) shown in cross-section at position AA. [Figure 3] This figure shows the usage status of the stopper-equipped dispenser (Figure 1). [Figure 4] This diagram shows a method for attaching a stopper to a cap that is fitted to the neck of the container body. [Modes for carrying out the invention]

[0015] Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 shows one embodiment of the stopper-equipped dispenser of the present invention when the holder body is in an upright position (locked state), where (a) is a plan view, (b) is a side view thereof, and (c) is an enlarged view of the pressing head and stopper portion of (b). Figure 2 shows one embodiment of the stopper-equipped dispenser of Figure 1 when the holder body is in an inverted position (unlocked state), where (a) is a plan view, and (b) is a cross-sectional view of the side view of (a) at position AA. Figure 3 shows the stopper-equipped dispenser of Figure 1 in use.

[0016] Reference numeral 1 in FIGS. 1 and 2 is a container body for containing and holding the contents, reference numeral 2 is a cap provided on the neck portion 1a of the container body 1, reference numeral 3 is a dispenser 3 inserted through the central portion of the cap 2 and fixedly held, and reference numeral 4 is a stopper detachably fitted and held on the cap 2.

[0017] The container body 1 has a filling space for the contents inside and a cylindrical neck portion 1a is provided at the top. The container body 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 body 1 is shown as an example, but the shape of the container can be appropriately changed based on the type of the contents, the design of the container, the use, etc., and is not limited to the illustrated shape.

[0018] The cap 2 is detachably attached by screwing a female screw 2a provided on the inner peripheral wall of the cap 2 onto a male screw 1b provided on the outer peripheral wall of the neck portion 1a of the container body 1 and by undercut fitting. Further, 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.

[0019] The dispenser 3 includes a pressing head 3a having a nozzle 3b for discharging the contents, and a piston disposed in a cylinder 3c is reciprocated by repeatedly pressing down the pressing head 3a downward, and the contents filled in the container body 1 are sucked into the cylinder 3c through a suction pipe 3d and pressurized and compressed to be discharged from the nozzle 3b of the pressing head 3a. Further, the dispenser 3 is fixedly held on the cap 2 by undercut fitting or the like.

[0020] The stopper 4 has a base 4a fitted and held to the cap 2, a holder body 4c rotatably held to the base 4a via a hinge 4b, a pair of arms 4d connected to the holder body 4c, and a push-in restricting plate 4e provided at the tip ends of the pair of arms 4d so as to be mutually inserted. The stopper 4 can be formed of a synthetic resin, but the material is not particularly limited. Also, in this embodiment, the stopper 4 has each constituent member integrally formed, but the constituent members can also be configured separately from each other.

[0021] The base 4a has a cylindrical peripheral wall 4a1 having an outer diameter slightly larger than the inner diameter of the cap 2 so as to cover the cap 2 from above, and a ring-shaped top wall 4a2 extending in the direction of the axis L of the container body 1 from the upper end of the peripheral wall 4a1. The base 4a is detachably fitted to the cap 2 by engaging a locking piece 4a3 provided at the lower end of the inner peripheral surface of the peripheral wall 4a1 with the lower edge of the cap 2, but the two may be fitted by an undercut fit.

[0022] Further, the base 4a has a mountain-shaped notch portion 4a4 having an arc shape upward in the peripheral wall 4a1. The notch portions 4a4 are preferably provided in a pair at diagonal positions on the peripheral wall 4a1. With the notch portions 4a4 (through the notch portions 4a4), the cap 2 can be operated (rotated) by a finger while the stopper 4 is attached to the cap 2, and the dispenser 3 (cap 2) can be detached from and attached to the container body 1. Therefore, for example, it is expected that after the content manufacturer fills the container body 1 with the content, the dispenser 3 can be attached to the container body 1 with the stopper 4 attached, or the user can attach and detach the dispenser 3 with the stopper 4 attached to refill or replace the content.

[0023] The holder body 4c is rotatably held to the outer peripheral edge of the top wall 4a2 of the base 4a via a hinge 4b. In this embodiment, the holder body 4c is held to the base 4a via a hinge 4b, but the base 4a may be omitted, and the holder body 4c may be directly attached to the cap 2 via a hinge.

[0024] The holder body 4c is configured to rotate via a hinge 4b ​​between the upright position shown in Figure 1 and the tilted position shown in Figure 2. The configuration of the holder body 4c will be described below based on the upright position shown in Figure 1. The holder body 4c has one or more vertical ribs 4c1 (three in the figure) connected to the hinge 4b, an upper surface portion 4c2 connected to the upper end of the vertical ribs 4c1, and a rib-shaped projection 4c3 provided on the side wall of the vertical rib 4c1 (located slightly above the center in the height direction) on the side facing the pressing head 3a, along the peripheral wall of the pressing head 3a. The projection 4c3 is configured to fit into the lower end of the pressing head 3a when the holder body 4c is in an upright position, as shown by the dotted line in Figure 1(c). As a result, the downward pressing of the pressing head 3a is prevented by the projection 4c3, preventing the contents from being unintentionally dispensed more than the nozzle 3b during storage or handling.

[0025] A pair of arms 4d are connected to both sides of the holder body 4c, respectively, and are positioned on both sides of the pressing head 3a in the upright position of the holder body 4c shown in Figure 1. In this embodiment, the arms 4d have a curved shape in plan view to match the shape (cylindrical) of the pressing head 3a, but this can be changed as appropriate to match the shape of the pressing head 3a, etc.

[0026] The push-in restricting plate 4e is provided at the tips of a pair of arms 4d, connecting the arms 4d together, and is positioned to cover the upper surface of the pressing head 3a when the holder body 4c in the upright position shown in Figure 1. This prevents the pressing head 3a from being unintentionally pressed down by fingers or other objects. In Figure 1, the push-in restricting plate 4e is approximately semicircular in plan view, but the shape of the push-in restricting plate 4e can be changed as appropriate.

[0027] Furthermore, the upper surface portion 4c2 of the holder body 4c has a locking claw 4c4 that extends away from the axis L of the container body 1. As shown in Figure 3, when the holder body 4c is rotated to an inverted position via the hinge 4b, the locking claw 4c4 engages with the lower end of the base 4a, thereby maintaining the holder body 4c in the inverted position. Note that if the base 4a is not provided as described above, and the holder body 4c is directly attached to the cap 2 via the hinge 4b, the locking claw 4c4 engages with the lower end of the cap 2.

[0028] Furthermore, when the holder body 4c is in an inverted position, as shown in Figure 3, a space is formed between the shoulder portion of the container body 1 and the pair of arms 4d (recess 4d1), and the back portion of the pair of arms 4d forms a suspension support portion 4f. As shown in the figure, the suspension support portion 4f allows the container to be suspended and held on a rod-shaped member 5 such as a towel rack.

[0029] When the holder body 4c is suspended from a rod-shaped member 5, such as a towel rack, via the suspension support portion 4e, it attempts to rotate to an upright position. However, the locking claw 4c4 catches on the lower end of the base 4a (circumferential wall 4a1), preventing the holder body 4c from rotating and thus preventing the container from falling off. In particular, by forming the hinge 4b, the locking claw 4c4, and the suspension support portion 4f at the same position in the radial or circumferential direction of the container, the engagement between the locking claw 4c4 and the base 4a can be effectively suppressed.

[0030] Figure 4 shows a method for attaching a stopper 4 to a cap 2 that is fitted onto the neck portion 1a of the container body 1. The stopper 4 is shown in cross-section at position AA in Figure 2. The stopper 4 is inserted from the direction of the tip of the nozzle 3b of the dispenser 3 through an opening formed by the ring-shaped top wall 4a2 of the base 4a, and can be easily attached to the cap 2 by engaging the locking piece 4a3, which is provided at the lower end of the inner circumferential surface of the peripheral wall 4a1 of the base 4a, with the lower edge of the cap 2, as described above. Since the stopper 4 can be attached to the cap 2 in a detachable manner, it can be reused by replacing the container when the contents are gone. [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]
