Description

[0001] Air fresheners can be dispersed into a room using a dispenser. Typically, the dispenser has a spray head that allows the fluid to be directed into the room. The spray head is activated to release the fluid in a specific direction in the room.

[0002] When a dispensing device is used in conjunction with a perfume to spray a fluid into a room, the direction of the spray may be important to the performance of the device. A misaligned spray head may be associated with reduced performance. For example, when the spray head is misaligned, the fluid may be dispensed in an undesirable direction, or the fluid may be at least partially sprayed onto the housing of the dispenser.

[0003] The present invention relates to a device for spraying a fluid, and in particular, but not exclusively, to a device for spraying a fluid such as a perfume, a deodorizing fluid and / or a pest control material etc. The invention also relates to a method of using such a device.

[0004] In a first aspect of the present invention, there is a refill for a liquid perfume dispensing device, the refill being configured to be inserted into the perfume dispensing device; wherein the refill comprises a rotatable spray head and a bottle, the rotatable spray head further comprising a nozzle; the spray head being configured to dispense liquid perfume from the bottle; wherein the spray head being configured to be rotated by the dispensing device by contacting at least one jaw of the dispensing device when the bottle is inserted into the dispensing device; and wherein the spray head further comprises at least one vertical rib, and the at least one vertical rib is configured to contact the at least one jaw to align the spray head in the dispensing device.

[0005] In another aspect, there is a rotatable spray head for a refill, the refill being configured to be inserted into a fragrance dispensing device; the rotatable spray head being attachable to the refill; the rotatable spray head comprising a nozzle, and the spray head being configured to dispense liquid fragrance from the refill via the nozzle; wherein the spray head is configured to be rotated by the dispensing device by contacting at least one jaw of the dispensing device when the bottle is inserted into the dispensing device; and wherein the spray head further comprises at least one vertical rib, and the at least one vertical rib is configured to contact the at least one jaw to align the spray head in the dispensing device.

[0006] On the other hand, there is a liquid perfume dispensing device, which includes a refill, the refill being configured to be inserted into the perfume dispensing device; wherein the refill includes a rotatable spray head and a bottle, the rotatable spray head also including a nozzle; the spray head is configured to dispense liquid perfume from the bottle; wherein the spray head is configured to be rotated by the dispensing device by contacting at least one jaw of the dispensing device when the bottle is inserted into the dispensing device; and wherein the spray head also includes at least one vertical rib, and the at least one vertical rib is configured to contact the at least one jaw to align the spray head in the dispensing device.

[0007] Aspects of the present disclosure are also described in detail, by way of example only, with reference to the accompanying drawings, in which:

[0009] Figure 1B showing the refill spray head in a second position during installation in a dispensing device;

[0010] Figure 1C The refill spray head is shown in a third position during installation in a dispensing device.

[0011] Figure 2 A refill spray head having locating ribs is shown;

[0012] Figure 3 The distribution device is shown in Figure 2 The nozzle.

[0013] Embodiments will now be described with reference to the accompanying drawings.

[0014] Figure 1A , Figure 1B and Figure 1C A spray head 6 for a refill is shown. These figures show a schematic representation of the placement of the refill into the dispensing device 4. As shown, the spray head 6 is rotated to the desired orientation of the spray head. The spray head 6 is configured to be rotatable, for example, the spray head 6 is configured to be attached to the refill so that it can rotate around the refill.

[0015] The spray head 6 comprises a circular portion 15 and a nozzle 14 for dispensing a fluid. In the example shown, the circular portion 15 is located on the opposite side of the spray head 6 relative to the nozzle 14. The dispensing device 4 comprises a mouth having a pair of jaws 16 and a spray head receiving portion 18.

[0016] like Figure 1A , Figure 1B and Figure 1CAs shown, the jaws 16 are configured to guide the spray head 6 so that the nozzle 14 is oriented so that the nozzle 14 is in a desired position. For example, the nozzle 14 of the spray head 6 is rotated by the jaws 16 to face the spray hole when docked in the spray head receiving portion 18. The jaws 16 cooperate with the circular portion 15 of the spray head 6 so that the nozzle 14 is in the correct orientation. For example, if the spray head 6 is not oriented correctly, one of the jaws 16 will contact the circular portion 15, thereby exerting a rotational force on the spray head 6. The rotational force causes the spray head 6 to rotate so that the nozzle 14 is correctly oriented, wherein the nozzle 14 faces the spray hole when docked in the spray head receiving portion 18.

[0017] Figure 1A The spray head 6 is shown entering the jaws 16 , with the nozzle 14 oriented in an undesired direction. Figure 1B The spray head 6 is shown in contact with one of the jaws 16. The contact between the jaws 16 and the spray head 6 causes the spray head 6 to rotate towards a desired orientation. Figure 1C The spray head 6 is shown docked in the spray head 6 receiving portion 18 , wherein the spray head is correctly oriented with the nozzle 14 facing the spray orifice.

[0018] The spray head 6 is shaped to contact the jaws 16 when the spray head 6 is in an undesirable orientation. In the example shown, the circular portion 15 of the spray head 6 includes a semicircular portion with straight portions on either side of the semicircular portion, and the nozzle 14 is at a side of the spray head opposite the semicircular portion, such as a "D" shape, and the jaws 16 are symmetrical to each other and include straight angled portions. Figure 1A , Figure 1B and Figure 1C As shown, the shapes of spray head 6 and jaws 16 cooperate so that one side of spray head 6 contacts one of jaws 16 to rotate the spray head so that spray head 6 moves to a desired orientation, such as an orientation in which the spray head is oriented toward a spray orifice.

[0019] Figure 2 Shown in more detail Figures 1A to 1C The nozzle 6 shown in FIG. Figure 2 The spray head 6 shown includes a circular portion 15, a side portion 1, a front portion 3, a rib 2, a top portion 5 and a nozzle 14. The spray head 6 is configured such that the nozzle 14 extends at least partially from the front portion 3 of the spray head 6. The circular portion 15 is connected to the front portion 3 via a pair of side portions 1. The rib 2 is located on the side portion 1. In the example shown, the spray head 6 includes a pair of ribs, each rib 2 being located on each of the pair of side portions 1. In the example shown, the ribs are located in a vertical orientation.

[0020] Figure 3 is an illustration of a cross section of a spray head 6 located in a dispensing device 4. The spray head 6 is positioned with the rib 2 in contact with the jaw 16 to assist in the alignment of the nozzle 14 of the spray head 6 in the dispensing device 4.

[0021] The rib 2 is configured such that it extends from the side portion 1. The rib 2 is configured to contact the jaws 16 when the spray head 6 is located in the dispensing device 4. The contact between the jaws 16 and the rib 2 helps align the nozzle. For example, the contact between the rib 2 and the jaws 16 reduces the degree of movement of the spray head 6 in the pair of jaws 16. The contact between the rib 2 and the jaws 16 of the spray head 6 reduces the rotational freedom of the spray head, thereby improving the alignment of the spray head 6.

[0022] Optimal alignment of the nozzle 14 relative to the device improves performance by reducing the amount of liquid dispensed in undesired directions. For example, misalignment of the nozzle may cause liquid ejected from the nozzle to be ejected onto components of the dispensing device, resulting in both undesired liquid on the dispenser and reduced spray range.

[0023] The size of the ribs is selected to provide optimal alignment of the nozzle 14 of the spray head 6 while limiting friction between the spray head and the jaws 16. For example, the size of the rib 2 is selected to properly align the nozzle 14 while maintaining the friction between the spray head 6 and the jaws 16 at a level that allows the mechanism to operate the spray mechanism reliably and efficiently. For example, the size of the rib 2 is selected so that the friction between the rib 2 and the jaws 16 is low enough to allow the motor to start the spray while helping with the alignment of the spray head.

[0024] In the example, the refill and dispensing mechanism are configured to dispense a non-aerosol liquid. Dispensing a non-aerosol liquid requires activating the spray head at sufficient speed to project the liquid into the room with a desired range. In this example, rib 2 is selected so that the mechanism of the dispensing device can apply sufficient speed to allow the spray to be ejected with sufficient range. The friction between rib 2 and jaw 16 can reduce the speed of the spray head when activated by the motor, and the rib size is selected to allow the motor to provide sufficient speed to the spray head to dispense the liquid into the room with a desired range.

[0025] In the example shown, the width of the rib 2 is a fraction of the width of the side portion 1. For example, the width of the rib is 10% to 30%, such as 15% to 25%, such as 18% to 22% of the side portion. In one example, the width of the rib is 1.2 mm and the width of the side portion is 5.8 mm.

[0026] exist Figure 2 In the example shown, the rib 2 has a wedge shape. For example, one part of the rib protrudes further from the side portion 1 than another part of the rib. Figure 2 In the example shown, the wedge shape is such that the rib 2 protrudes further at the portion of the rib close to the top portion 5 of the spray head 6 than at the portion of the rib farthest from the top portion 5 of the spray head 6 .

[0027] In the example shown, the rib 2 extends from the side portion at maximum extension by 0.2% to 1%, such as 0.4% to 0.8%, such as 0.5% to 0.7%, such as 0.6%, of the width of the spray head.

[0028] In the example shown, the wedge shape of the rib 2 forms an angle of 1% to 2% with the side portion of the spray head, for example, the angle is 1.2% to 1.8%, for example, the angle is 1.3% to 1.5%. In another example, the extension of the rib from the side of the spray head is constant, that is, the extension of the rib from the side of the spray head is uniform.

[0029] In the above example, the spray head is molded with ribs 2 extending from the side portion 1. In other examples, the spray head may include ribs that are formed separately and attached to the side portion 1.

[0030] In the described example, the dispensing device dispenses a liquid perfume. The dispensing device may also dispense a deodorizing fluid and / or a pest control material, etc.

[0031] Further modifications and developments may be made without departing from the scope of the invention described herein.
