[0012] According to the present invention, it is possible to provide a spray container that can discharge contents in both a mist form and a liquid form as required. Brief Description of the Drawings

[0013] [Figure 1] It is a cross-sectional view showing the spray container of one embodiment of the present invention in a first state. [Figure 2] It is a cross-sectional view showing the spray container shown in Figure 1 in a second state. Modes for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described by way of example with reference to the drawings.

[0015] As shown in Figures 1 to 2, in one embodiment of the present invention, the spray container 1 includes a container body 2 having a mouth portion 2a, and a dispenser 3. The dispenser 3 is a discharge pump having a cylinder 4 and an operating portion 5 that discharges the liquid in the container body 2 through the cylinder 4 by performing a reciprocating motion relative to the cylinder 4. The cylinder 4 is integrally supported by the mouth portion 2a, and the operating portion 5 reciprocates in the vertical direction relative to the cylinder 4. The discharge pump is a trigger-type discharge pump having a trigger 6 that causes the operating portion 5 to perform a reciprocating motion relative to the cylinder 4 by receiving a pulling operation. The dispenser 3 may be a discharge pump other than a trigger-type one, or may be a dispenser 3 other than a discharge pump. The liquid stored in the container body 2 is not particularly limited, and is, for example, a liquid for sunscreen, cosmetics, insect repellent, or the like.

[0016] The container body 2 has a mouth portion 2a, a body portion 2b, and a bottom portion (not shown) connected in this order. The mouth portion 2a has a cylindrical shape centered on the central axis O. In the present embodiment, the direction from the bottom portion toward the mouth portion 2a along the central axis O is referred to as upward, the opposite direction is referred to as downward, the direction orthogonal to the central axis O is referred to as the radial direction, and the direction orbiting the central axis O is referred to as the circumferential direction. Further, among the radial directions, the direction in which the trigger 6 is operated is referred to as the front-rear direction, and in the front-rear direction, the direction in which the trigger 6 is swung by being pulled is referred to as rearward.

[0017] The discharger 3 includes a discharger body 7 mounted on the mouth portion 2a, and a nozzle cover 8. The discharger body 7 has a spray nozzle 7a extending in the nozzle axial direction along the nozzle axis P, the spray nozzle 7a has a spray port 7a1 that sprays the liquid in the container body 2 in a mist form in the nozzle axial direction. The nozzle cover 8 has a mounting cylindrical portion 8a mounted on the outer peripheral surface of the spray nozzle 7a, and a discharge cylindrical portion 8c rotatably connected to the mounting cylindrical portion 8a via a hinge portion 8b between a first position and a second position. A first state (the state shown in FIG. 1) in which the discharge cylindrical portion 8c is held at the first position, and a second state (the state shown in FIG. 2) in which the discharge cylindrical portion 8c is held at the second position can be selected.

[0018] The nozzle axis P extends in a direction not parallel to the vertical direction, and the spray port 7a1 faces forward. Note that the nozzle axis P may be configured to extend in the vertical direction.

[0019] The mounting cylindrical portion 8a has a cylindrical shape extending in the nozzle axial direction. The discharge cylindrical portion 8c has a proximal cylindrical portion 8c3 and a distal cylindrical portion 8c4, and extends linearly in the nozzle axial direction in the first state. The inner peripheral surface of the proximal cylindrical portion 8c3 defines a linear flow path C1. The inner peripheral surface of the distal cylindrical portion 8c4 defines a bent portion C2 and a discharge port side flow path C3. The discharge cylindrical portion 8c has a discharge flow path C extending from the introduction port 8c1 to the discharge port 8c2, and the discharge flow path C includes the linear flow path C1 extending from the introduction port 8c1 in the nozzle axial direction in the first state, the bent portion C2 that bends at the distal end of the linear flow path C1 in a predetermined cross section including the nozzle axis P, and the discharge port side flow path C3 extending from the bent portion C2 to the discharge port 8c2. The discharge port 8c2 faces downward. Note that the discharge port 8c2 is not limited to the configuration facing downward.

[0020] In the first state, the discharge channel C collects the atomized liquid introduced from the inlet 8c1 and discharges it as a liquid from the discharge port 8c2. The second position is where the discharge cylinder 8c avoids the liquid ejection path from the spray port 7a1, and in the second state, the discharger 3 ejects the liquid as a mist from the spray port 7a1 to the outside of the discharger 3.

[0021] With the above configuration, by switching between the first and second states as needed, the liquid can be dispensed in both mist and liquid form. In other words, it is possible to dispense in two forms: mist and liquid.

[0022] From the viewpoint of discharging a mist of liquid in a sufficiently liquid state in the first state, it is preferable that the length La of the straight channel C1 is 10 mm or more, and the bending angle θ of the curved section C2 is 25° or more. Furthermore, from the viewpoint of reducing the amount of liquid that remains attached to the discharge channel C without being discharged in the first state, thereby enabling quantitative discharge by the pump, and also from the viewpoint of suppressing the overall length of the nozzle cover 8, it is preferable that the length L of the discharge channel C is 26 mm or less. The length L of the discharge channel C is expressed as the sum of the length La of the straight channel C1 and the length Lb of the discharge port side channel C3, where L = La + Lb.

[0023] In the predetermined cross-section, the side on which the discharge port 8c2 is located, straddling the nozzle axis P, is called the nozzle side, and the opposite side is called the nozzle side. The hinge portion 8b is provided on the nozzle side, the discharge cylinder portion 8c has a locking recess 8c5 on the nozzle side, and the mounting cylinder portion 8a has a locking projection 8a1 on the nozzle side that locks the locking recess 8c5 in the second state. Therefore, the second state can be achieved from the first state by a simple operation of rotating the discharge cylinder portion 8c via the hinge portion 8b to fit the locking recess 8c5 into the locking projection 8a1.

[0024] The locking projection 8a1 has a base portion 8a2 that protrudes from the outer circumferential surface of the mounting cylinder portion 8a toward the other side of the nozzle, and a locking portion 8a3 that protrudes from the base portion 8a2 toward the tip side in the direction of the nozzle axis, and the locking recess 8c5 has a hooking portion 8c6 that catches on the surface of the locking portion 8a3 toward one side of the nozzle in the second state. Therefore, the discharge cylinder portion 8c can be stably held in the second position in the second state.

[0025] The base end surface of the discharge cylinder portion 8c has an annular recess 8c7 that encircles the inlet 8c1, and the tip surface of the mounting cylinder portion 8a has an annular projection 8a4 that engages the annular recess 8c7 in the first state. Therefore, the discharge cylinder portion 8c can be rotated via the hinge portion 8b to engage the annular recess 8c7 with the annular projection 8a4 in a simple operation, thereby returning to the first state from the second state.

[0026] The nozzle cover 8 is made of resin. However, the nozzle cover 8 is not limited to being made of resin.

[0027] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and the embodiments described above can be modified in various ways without departing from the spirit of the present invention.
