Description

Technical Field

[0001] This invention relates to the field of apparatus and systems for delivering volatile compositions, and more particularly to a volatile composition dispenser having an actuating lever, and a method for activating the volatile composition dispenser. Background Technology

[0002] Systems for delivering volatile substances into the atmosphere are well known in the art and include, for example, insect repellents, air fresheners, and odor removers. Such systems function by evaporating volatile substances into space through a medium, such as a permeable membrane, to provide a variety of benefits, such as air freshening or odor removal, or a combination thereof. Typically, the volatile composition is stored in a sealed container that is opened or punctured to release the volatile composition into the air.

[0003] PCT Publication No. WO 98 / 16262 (hereinafter referred to as "WO98 / 16262") describes a disposable air freshener dispenser device with a button actuator that can be manually operated to initiate the dispensing of an air freshener composition into the atmosphere. The device of WO98 / 16262 includes an air freshener medium within a container and a button actuator that can be manually operated to rupture the foil covering the container, thereby initiating the dispensing of air freshener into the atmosphere.

[0004] However, after the foil breaks, the button actuator remains on the opening inside the foil and blocks the path for dispensing the air freshener. Therefore, there is a need for a mechanism that allows the foil to break without impeding the dispensing of the air freshener.

[0005] Another problem associated with such devices is that users (such as consumers) cannot determine whether an air freshener has been activated until they smell the air freshener composition. Therefore, if a consumer does not smell the air freshener composition, they may assume the device is not activated or is malfunctioning, leading to reduced consumer satisfaction. Another issue with existing devices is that other users (such as retail owners) cannot easily detect whether such devices have been tampered with or accidentally activated during handling or transportation to the retail store. This could result in defective air fresheners being displayed for sale, inevitably leading to consumer complaints when consumers purchase them. Therefore, there is a need for a device for delivering volatile substances that can be manually operated and simultaneously provides the user with a signal indicating that the device has been activated. Summary of the Invention

[0006] To address the above-mentioned needs, the present invention provides a volatile composition dispenser, the volatile composition dispenser comprising:

[0007] (a) A barrel comprising a reservoir of at least one liquid volatile composition and a ruptureable substrate for sealing the reservoir;

[0008] (b) A housing defining an internal compartment in which the barrel is disposed, wherein a frame opening is formed through the housing and defines an extending surface in which the frame opening extends; and

[0009] (c) An actuating lever, disposed at the frame opening and configured to pivot relative to the housing, wherein the actuating lever includes a hammer portion and a handle portion.

[0010] The actuating rod is configured to pivot between a first position and a second position, in which the hammer portion of the actuating rod extends below the extended surface of the frame opening and into the internal compartment of the housing, and the handle portion of the actuating rod extends above the extended surface of the frame opening and outside the housing, in which the hammer portion of the actuating rod causes the fractured substrate of the barrel to fracture to release at least one liquid volatile composition from the fractured substrate.

[0023] This invention relates to a dispenser for delivering volatile substances into the atmosphere. The dispenser is suitable for providing fragrances, air fresheners, deodorants, odor eliminators, odor neutralizers, insecticides, insect repellents, pharmaceutical substances, disinfectants, cleaning agents, mood enhancers, aromatherapy adjuncts, or for any other purpose using volatile substances or volatile compositions for regulating, modifying, or otherwise altering the atmosphere or environment. For the purpose of detailed illustration, but not for limiting the scope of the invention, the invention will be described in the context of a dispenser for delivering liquid compositions comprising fragrances, fragrance ingredients, and / or fragrance raw materials.

[0024] Figure 1 A front perspective view of an embodiment of the volatile composition dispenser 1 according to the present invention is shown, and Figure 2 A rear perspective view of the dispenser 1 is shown. The volatile composition dispenser 1 includes a housing 10 having a front cover 100 and a rear frame 200, which define an internal compartment. The rear frame 200 has a frame opening 201 located substantially at the center of the rear frame 200. An actuation lever 20 is disposed within the frame opening 201 and is pivotable relative to the rear frame 200 to allow a user to activate the volatile composition dispenser 1. A cartridge 30 containing the volatile composition 31 is located within the housing 10.

[0025] Figure 3The internal components of the volatile composition dispenser 1 are shown. The front cover 100 includes a window 101 configured to display the cartridge 30. The cartridge 30 includes a container 32 with an orifice 321, and a volatile composition 31 (such as...) Figure 1 (As shown) The container 32 is stored within the orifice. A fractured substrate 33 is sealably attached to and covers the orifice 321 defining the reservoir to prevent the release of the volatile composition 31 until the volatile composition dispenser 1 is activated. The fractured substrate 33 can be fractured to release the volatile composition 31 by actuating a fracture mechanism 34 positioned adjacent to the fractured substrate 33. The fracture mechanism 34 includes a movable member 35 movably attached to an outer frame 36 via an elastic member 38. The elastic member 38 may be formed of one or more springs 38. One or more fracture elements 37 are arranged within the fracture mechanism 34 to pierce a hole in the fractured substrate 33. The fracture element 37 may be a pin, tooth, or spike. The cartridge 30 may include a permeable membrane 39 located outside the cartridge 30. The permeable membrane 39 is sealably attached to a flange 322 located at the periphery 323 of the container 32. The breathable membrane 39 encloses the container 32, the volatile composition 31, the fracture substrate 33, and the fracture mechanism 34. The breathable membrane 39 may be configured to bend when pressure or actuation is applied to the breathable membrane 39.

[0026] Figure 4 This is a rear perspective view of the rupture mechanism 34 of the volatile composition dispenser 1. The rupture mechanism 34 includes an outer frame 36 and a movable member 35 movably attached to the outer frame 36 by means of an elastic member 38. The movable member 35 includes a substantially flat first surface facing the breathable membrane 39 and a second surface opposite the first surface and facing the ruptureable substrate 33. When a force is received on the first surface of the movable member 35 during actuation of the actuating lever 20, the movable member 35 can move relative to the outer frame 36 by bending of the elastic member 38. The elastic member 38 may be a spring that elastically connects the outer frame 36 to the movable member 35.

[0027] In such Figure 4In one embodiment shown, a pair of rupture elements 37 are spaced apart on the movable member 35 and extend from opposite edges 347 of the movable member 35, wherein each rupture element 37 includes a tip for piercing the ruptureable substrate 33. It is understood that more than two rupture elements 37 or only one rupture element 37 may be provided, and the rupture elements 37 may be located at any suitable location on the movable member 35. For example, a first rupture element 37 may be disposed on a first opposite edge of the movable member 35, and a second pair of rupture elements 37 may be disposed on a second opposite edge of the movable member 35, different from the first opposite edge, to allow the cartridge 30 to be used in different orientations. The positions of the rupture elements 37 are configured to pierce the ruptureable substrate 33 to allow air to enter the container 32 and exit the volatile composition from the container 32.

[0028] Furthermore, in embodiments not shown, the movable member 35 may include one or more elongated ribs arranged to increase the rigidity or stiffness of the movable member 35. For example, the elongated ribs may project from the second surface and extend from the edge of the movable member 35 and converge at the center of the movable member 35.

[0029] like Figure 4 As shown, the elastic member 38 can be a spring or a parallel spring system. The spring can be a beam or a torsion member. In one embodiment, the elastic member 38 is a torsion member, which may include a first arm 382 attached to the outer frame 36, a second arm 383 attached to the movable member 35, and an elongated channel member 384 extending between the first arm 382 and the second arm 383. In one embodiment, the elongated channel member 384 includes two substantially parallel side beams 385 and a bottom beam 386 to form a substantially U-shape.

[0030] To activate the volatile composition dispenser 1, the user presses down the activation lever 20 until it contacts the rupture mechanism 34 and pushes it further (through the permeable membrane 39), and the rupture element 37 (such as a pin, tooth, or serration) on the rupture mechanism 34 pierces the ruptureable substrate 33. Once the ruptureable substrate 33 is pierced, the volatile composition 31 flows out of the container 32, wets the permeable membrane 39, and is then delivered into the surrounding atmosphere by evaporation from the permeable membrane 39.

[0031] According to one embodiment of the invention, the actuation lever 20 and the rear frame 200 are configured to enable the fracturing substrate 33 in the barrel 30 to fracture effectively and in a controlled manner, while also providing the user with a tactile and intuitive user experience to activate the volatile composition dispenser 1.

[0032] The frame opening 201 may be substantially located in the center of the rear frame 200 and defines an extension surface 202 in which the frame opening 201 extends. An actuating rod 20 is disposed within the frame opening 201 and is pivotable relative to the rear frame 200. The frame opening 201 may be formed as a through hole in the rear frame 200. For example, according to one embodiment of the invention, an inner wall 40 may be disposed at the periphery of the frame opening 201 and extend from the interior of the rear frame 200 into the housing 10. The inner wall 40 defines the frame opening 201. In the illustrated embodiment, the inner wall 40 is solid and tubular in shape. However, the inner wall 40 may take some other shapes, such as, for example, a square or rectangular cross-section. The inner wall 40 may be substantially cylindrical and comprise continuous or segmented walls, such as, for example, a grid structure or a plurality of elongated struts connected to each other. The inner wall 40 may define the frame opening 201 as an extension into the housing 10, wherein a central longitudinal axis extends through the center of the frame opening 201. The inner wall 40 may be configured to allow the actuating lever 20 (at least a portion of the actuating lever 20) to pivot freely within the inner wall 40. In the illustrated embodiment, the inner wall 40, the actuating lever 20, and the rear frame 200 may comprise plastic for ease of manufacture. Alternatively, the inner wall 40, the actuating lever 20, and the rear frame 200 may comprise a sheet of metal such as spring steel and may be stamped or milled.

[0033] According to one embodiment of the present invention, such as Figures 5 to 6 As shown, the actuating lever 20 is connected to the rear frame 200 of the housing 10 via a hinge structure 230 at the frame opening 201, allowing the actuating lever 20 to pivot relative to the rear frame 200. Furthermore, as... Figure 6 As shown, the actuating lever 20 is pivotally connected to the inner wall 40.

[0034] The hinge structure 230 is configured to allow the actuating lever 20 to pivot relative to the rear frame 200. For example... Figure 6As shown, the hinge structure 230 includes a pivot located inside the frame opening 201 and connected to the rear frame 200 (particularly the inner wall 40) of the housing 10. The pivot may be, for example, in the form of a pin. According to one embodiment, the pivot is fixed to or integral with the rear frame 200 of the housing 10, and the actuating rod 20 also includes a through hole into which the pivot is fitted, such that the actuating rod 20 is pivotable about the pivot and thus relative to the rear frame 200 of the housing 10. According to another embodiment, the rear frame 200 of the housing 10 also includes two blind holes at the frame opening 201, into which the pivot is fitted respectively; that is, each of the two ends of the pivot is fitted into one of the two blind holes, such that the pivot is supported by the rear frame 200 of the housing 10 and rotatably fitted within the two blind holes. The starter lever 20 is fixed to or integrated with the pivot axis, such that the starter lever 20 can pivot relative to the rear frame 200 of the housing 10 by means of the pivot axis.

[0035] According to one embodiment of the present invention, such as Figures 7A to 11 As shown, the actuating lever 20 includes a hammer portion 210 for actuating the fracturing mechanism 34 to pierce the fracturable substrate 33 and a handle portion 220 for user manipulation (such as pushing). The hammer portion 210 and the handle portion 220 may be formed as a single piece, such that the actuating lever 20 may be an integrally molded part. Alternatively, the hammer portion 210 and the handle portion 220 may be formed separately and then joined or fixed to each other. The hammer portion 210 and the handle portion 220 may be joined to each other at a hinge structure 230.

[0036] The handle portion 220 of the actuating lever 20 may be in the form of a tab, plate, or rod. Similarly, the hammer portion 210 of the actuating lever 20 may be in the form of a tab, plate, or rod. The hammer portion 210 of the actuating lever 20 has an end opposite to the handle portion 220, wherein this end may be rounded to facilitate the hammer portion 210 pushing the breaking mechanism 34 during the pivoting movement of the actuating lever 20. Figure 5 and Figure 6 In the illustrated embodiment, the end of the hammer portion 210 of the actuating lever 20 includes a first end 211 and a second end 213 separated from each other by a recess 212. The recess 212 is formed between the first end 211 and the second end 213.

[0037] According to one embodiment of the invention, the length of the handle portion 220 of the actuating lever 20 is 20% to 150%, or 50% to 120%, or 70% to 100% of the length of the hammer portion 210 of the actuating lever 20. It is desirable that the handle portion is not disproportionately longer or larger than the hammer portion, so that the protruding handle portion provides a clear visual signal to the consumer of the device's pre-start state without causing significant space obstruction during transport or storage. The length of the handle portion 220 is the length extending from the connection between the hammer portion 210 and the handle portion 220 in the direction of the handle portion 220, such as the length of the handle portion 220 in... Figures 7A to 7C The length extending within the page. Similarly, the length of the hammer portion 210 is the length extending from the connection between the hammer portion 210 and the handle portion 220 in the direction of the hammer portion 210, such as the hammer portion 210 in... Figures 7A to 7C The length extended within the page.

[0038] According to one embodiment of the invention, the handle portion 220 and the hammer portion 210 of the actuating lever 20 form an angle of 90° to 180°, or 100° to 170°, or 120° to 160°, or 130° to 150°, or preferably 145°. Generally speaking, such an angle can be considered as the angle formed by the length extension of the hammer portion 210 and the length extension of the handle portion 220. Figures 7A to 7C and Figures 9A to 9C As shown, the angle formed by the handle portion 220 and the hammer portion 210 is an obtuse angle, and as... Figure 11 As shown, the angle formed by the handle portion 220 and the hammer portion 210 is a straight angle, wherein the length extension of the hammer portion 210 coincides with or aligns with the length extension of the handle portion 220. In a particular embodiment, the angle between the handle portion 220 and the hammer portion 210 is an obtuse angle (similar to...). Figure 11 The angle shown allows the handle portion 220 to start from an upright pre-start position and end in a flush or substantially parallel post-start position relative to the rear frame 200, while the hammer portion can be effectively moved from an inclined pre-start position to a vertically downward start position and end in an inclined post-start position relative to the rear frame 200 (as shown). Figures 7A to 7C (As shown).

[0039] The above description of the size, shape, and structure of the actuating lever 20 is for illustrative purposes only and not for limitation. Those skilled in the art will understand that the actuating lever 20 may take any suitable size, shape, and structure without departing from the spirit and scope of the invention.

[0040] According to one embodiment of the invention, the actuating lever 20 is configured to pivot between a first position and a second position. In the first position, as... Figure 7A , Figure 8A , Figure 9A and Figure 10A As shown, the hammer portion 210 of the actuating lever 20 extends below the extended surface 202 of the frame opening 201 and into the internal compartment of the housing 10, while the handle portion 220 of the actuating lever 20 extends above the extended surface 202 of the frame opening 201 and outside the housing 10. The handle portion 220 of the actuating lever 20 protrudes beyond the housing, thus providing the user with a clear visual cue that the volatile composition dispenser 1 is currently in a pre-start state (i.e., the volatile composition dispenser 1 is not activated). Additionally, this configuration of the handle portion 220 facilitates the user pushing the handle portion 220 to activate the volatile composition dispenser 1. In the second position, as... Figure 7B , Figure 8B , Figure 9B and Figure 10B As shown, the hammer portion 210 of the actuating rod 20 causes the fractured substrate 33 of the barrel 30 to fracture, thereby releasing at least one liquid volatile composition 31 from the fractured substrate. The terms "above" and "below" as used herein are based on, for example... Figures 7A to 7C and Figures 9A to 9C The orientation of the components in the diagram is defined. When the user pushes the actuating lever 20 to pivot from the first position to the second position, the handle portion 220 of the actuating lever 20 is pushed, thus pivoting the actuating lever 20 about the pivot axis of the hinge structure 230, and therefore pivoting relative to the rear frame 200 of the housing 10. Both the hammer portion 210 and the handle portion 220 of the actuating lever 20 pivot about the pivot axis. During the pivoting of the actuating lever 20 from the first position to the second position, the hammer portion 210 of the actuating lever 20 applies force to the rupture mechanism 34 and moves the rupture mechanism 34 to rupture the ruptureable substrate 33 in the barrel 30 and release at least one liquid volatile composition 31 from the ruptureable substrate.

[0041] According to one embodiment of the present invention, such as Figures 7A to 10C As shown, during the movement of the actuating lever 20, the position of the actuating lever 20 relative to the rear frame 200 of the housing 10 will change, and the angles of the hammer portion 210 and the handle portion 220 of the actuating lever 20 relative to the extension surface 202 extending therein from the frame opening 201 will also change. In the first position, as... Figure 7A and Figure 9A As shown, the handle portion 220 of the actuating lever 20 extends away from the extending surface 202 at an angle of 30° to 150°, or 45° to 135°, or 60° to 120°, or preferably 90°, and the hammer portion 210 of the actuating lever 20 extends away from the extending surface 202 at an angle of 10° to 80°, or 20° to 60°, or 30° to 40°, or preferably 35°. In the second position, as... Figure 7B and Figure 9BAs shown, the hammer portion 210 of the starter lever 20 will be changed to extend away from the extension surface 202 at an angle of 70° to 110°, or 80° to 100°, or 85° to 95°, or preferably 90°.

[0042] According to one embodiment of the present invention, such as Figures 7A to 10C As shown, the actuating lever 20 is further configured to pivot from a second position to a third position, in which the handle portion 220 of the actuating lever 20 extends in a direction substantially parallel to the extending surface 202 of the frame opening 201, as... Figure 7C , Figure 8C , Figure 9C and Figure 10C As shown. In this configuration, the actuating lever 20 can pivot further beyond the second position after reaching it. In the third position, the handle portion 220 of the actuating lever 20 is substantially parallel to the extended surface 202 of the frame opening 201, providing the user with a clear visual cues that the volatile composition dispenser 1 is currently in the post-start state (i.e., the volatile composition dispenser 1 has been fully activated). Furthermore, this configuration of the handle portion 220 provides an aesthetically pleasing appearance for the volatile composition dispenser 1, such as... Figure 8C and Figure 10C As shown. The term "substantially parallel" indicates that the angle formed between the handle portion 220 of the actuating lever 20 and the extension surface 202 of the frame opening 201 can be in the range of -15° to 15°. In the third position, the hammer portion 210 of the actuating lever 20 extends away from the extension surface 202 at an angle of 45° to 70°, or 50° to 65°, or 55° to 60°, or preferably 60°.

[0043] According to one embodiment of the invention, once the actuating lever 20 reaches the third position, the actuating lever can be locked in that position. Figures 5 to 6 As shown, the volatile composition dispenser 1 includes a first stop 241 and a second stop 242. Both the first stop 241 and the second stop 242 may be located within the frame opening 201 and preferably opposite each other. Figure 6 As shown, the first stop 241 is opposite to the second stop 242 in a direction perpendicular to the pivot axis of the hinge structure 230. In the third position, the first stop 241 interacts with the end of the handle portion 220 of the actuating lever 20 to prevent the actuating lever 20 from pivoting rearward from the third position to such a position as the second position or the first position, and the second stop 242 interacts with the hammer portion 210 of the actuating lever 20 to prevent the actuating lever 20 from pivoting further from the third position, such as beyond the third position, so that the actuating lever 20 is locked in the third position.

[0044] The first stop 241 may be disposed on the inner wall 40 and in the form of a protrusion extending from the inner wall 40 toward the center of the frame opening 201. In one embodiment, the first stop 241 may form a snap-fit ​​engagement with the end of the handle portion 220 of the actuating lever 20. During pivoting of the actuating lever 20 between a first position and a second position, the first stop 241 will not contact the end of the handle portion 220 of the actuating lever 20. During pivoting of the actuating lever 20 from the second position to a third position, the end of the handle portion 220 will contact the first stop 241, and the handle portion 220 of the actuating lever 20 needs to overcome the interaction between the end of the handle portion 220 and the first stop 241 to move beyond the first stop 241. After the handle portion 220 of the actuating lever 20 has moved beyond the first stop 241 and the actuating lever 20 has reached its third position, the first stop 241 is configured to prevent the actuating lever 20 from pivoting rearward from the third position to positions such as the second position and / or the first position, as... Figure 7C and Figure 9C As shown.

[0045] The second stop 242 may be disposed on the inner wall 40 and take the form of a platform or block extending from the inner wall 40 toward the center of the frame opening 201. During pivoting of the actuating lever 20 between the first and second positions, the second stop 242 will not contact the hammer portion 210 of the actuating lever 20. When the actuating lever 20 pivots from the second position to the third position, the hammer portion 220 will contact and be blocked by the second stop 242 to prevent the actuating lever 20 from pivoting further from the third position, such as beyond the third position. Figure 7C and Figure 9C As shown. Therefore, the actuating lever 20 can be locked in the third position by the combination of the first stop 241 and the second stop 242.

[0046] Generally, it is desirable that the actuating lever 20 remain in its first position before being used by the user. In fact, it is preferable that the actuating lever 20 remain in the first position to prevent it from being accidentally actuated and thus activating the volatile composition dispenser 1, but be easily pushed to activate the volatile composition dispenser 1 when the user wants to use it. According to one embodiment of the invention, a retaining element 243 is provided to achieve this effect. The actuating lever 20 is stabilized to the rear frame 200 of the housing 10 and held in the first position by the retaining element 243. The retaining element 243 is connected between the actuating lever 20 and the inner wall 40. Alternatively, in the case of a second stop 242, the retaining element 243 may be connected between the actuating lever 20 and the second stop 242, such as... Figure 5 and Figure 6As shown. When the actuating lever 20 pivots from the first position to the second position, the retaining element 243 is removed or broken to allow the actuating lever 20 to move. The retaining element 243 can be broken by applying pressure to the handle portion 220 of the actuating lever 20. Such pressure can be generated by a user pushing the handle portion 220 of the actuating lever 20, and the actuating lever 20 can be pivoted from the first position to the second position by such pressure. For example, the retaining element 243 may be in the form of a tab or sheet with a weakening line that will break when the user pushes the handle portion 220 of the actuating lever 20.

[0047] The following will refer to Figures 7A to 10C The operation of the volatile composition dispenser 1 according to the present invention is described.

[0048] The volatile composition dispenser 1 includes a pre-start state, a start state, and a post-start state. Figure 7A and Figure 8A The pre-start state of the volatile composition dispenser 1 is shown. In the pre-start state, the actuating lever 20 is stabilized to the rear frame 200 of the housing 10 and held in a first position by the retaining element 243. The hammer portion 210 of the actuating lever 20 extends below the extended surface 202 of the frame opening 201 and into the internal compartment of the housing 10, while the handle portion 220 of the actuating lever 20 extends above the extended surface 202 of the frame opening 201 and outside the housing 10, providing the user with a clear visual cue that the volatile composition dispenser 1 is currently in the pre-start state. The hammer portion 210 of the actuating lever 20 may contact or be separated from the breathable membrane 39 by a certain distance. The rupture mechanism 34 is clamped between the breathable membrane 39 and the ruptureable substrate 33 and is not pushed by the hammer portion 210 of the actuating lever 20 to contact and puncture the ruptureable substrate 33.

[0049] When a user wants to activate the volatile composition dispenser 1 to release at least one liquid volatile composition 31 from the dispenser, he / she can push the handle portion 220 of the activation lever 20, for example, by pushing the handle portion 220 towards... Figures 7A to 7C On the left side, the starter lever 20 is pivoted from the first position to the second position to activate the volatile composition dispenser 1 from the pre-start state to the start state. Figure 7B and Figure 8BThe volatile composition dispenser 1 is shown in its activated state. During the transition from the pre-activated state to the activated state, the retaining element 243 is broken by pushing the handle portion 220 of the actuating lever 20, and then the actuating lever 20 pivots from a first position to a second position. In the activated state, the hammer portion 210 of the actuating lever 20 pivots to apply pressure to the permeable membrane 39, which bends toward the rupture mechanism 34, and then applies pressure to the rupture mechanism 34, particularly its movable member 35. The rupture mechanism 34, particularly its movable member 35, will move toward the ruptureable substrate 33 under such pressure and puncture the ruptureable substrate using the rupture element 37. In some cases, the ruptureable substrate 33 may also bend downward as the movable member 35 of the rupture mechanism 34 moves downward. At least one liquid volatile composition 31 can be released from the container 32 through a hole formed in the ruptureable substrate 33 by the rupture element 37 of the rupture mechanism 34 piercing the ruptureable substrate 33.

[0050] As the handle portion 220 of the actuating lever 20 is continued to be pushed, the actuating lever 20 will pivot further from the second position to the third position to place the volatile composition dispenser 1 from the activated state to the post-activated state. During this period, the pressure applied to the rupture mechanism by the hammer portion 210 of the actuating lever 20 will decrease with further pivoting of the actuating lever 20. The rupture mechanism 34 can move rearward (upward) due to the elastic force of the elastic member 38. In this case, the ruptureable substrate 33 and the breathable membrane 39 can be adaptively bent.

[0051] By means of the actuation lever 20, which pivots from the first position through the second position and reaches the third position, a clicking sound effect is obtained when the user pushes the handle portion 220 of the actuation lever 20, which provides a pleasant feeling for the user.

[0052] Figure 7C and Figure 8C The volatile composition dispenser 1 is shown in its activated state. In this activated state, the handle portion 220 of the actuator 20 extends in a direction substantially parallel to the extending surface 202 of the frame opening 201, thereby providing an aesthetically pleasing appearance for the volatile composition dispenser 1. Figure 7CAs shown, the hammer portion 210 of the actuating lever 20 remains in contact with the permeable membrane 39 and applies pressure to the permeable membrane 39 and the rupture mechanism 34. The rupture mechanism 34, particularly its movable member 35, returns only partially rather than fully to its original position. In this case, the hole formed in the ruptureable substrate 33 is large enough to be partially exposed. Alternatively, in an embodiment not shown, in the activated state, the hammer portion 210 of the actuating lever 20 may separate from the permeable membrane 39 and no longer apply pressure to the rupture mechanism 34. In this case, the hole formed in the ruptureable substrate 33 can be fully exposed to release at least one liquid volatile composition 31. Due to at least partial return of the movable member 35 of the rupture mechanism 34, the hole formed in the ruptureable substrate 33 can be at least partially exposed to facilitate the release of at least one liquid volatile composition 31.

[0053] Figures 9A to 10C It shows the relationship with Figures 7A to 8C A similar implementation scheme, the difference being that the starter lever 20 is in relation to... Figures 7A to 8C It pivots in the opposite direction to the direction of rotation. Figures 7A to 7C In the middle, the handle portion 220 is pushed to the left, and... Figures 9A to 9C In the middle, the handle portion 220 is pushed to the right.

[0054] The volatile composition dispenser 1 may include a small form factor, such as that of a computer mouse, to ergonomically fit the user's hand and be easy to use. Figure 3 The internal components of the shown container 30 can be characterized as follows. For example, the container 32 can be sized to hold about 1 ml to about 50 ml of a liquid volatile composition. Alternatively, the reservoir can hold about 2 ml to about 30 ml, or about 2 ml to about 10 ml, or about 2 ml to about 8 ml, or about 4 ml to about 6 ml, or about 2 ml, or about 6 ml of a liquid volatile composition.

It is also envisioned that coated barrier films can be used as fracture-resistant substrates 33. Such coated barrier films may be used, including films coated with metallized PET, metallized polypropylene, silica, or alumina. Any barrier material, whether coated or uncoated, may be used alone and / or in combination with other barrier materials.

[0056] The rupture element 37 can be manufactured using polyolefins (such as polyethylene or polypropylene), polyesters, or other plastics known to be suitable for molding, by injection molding, compression molding, or pressure molding. The rupture element 37 can also be manufactured by thermoforming using discrete cutting steps to remove unwanted portions.

Additionally, the breathable membrane 39 may be filled with any suitable fillers and plasticizers known in the art. Fillers may include silica powder, clay, zeolite, carbonates, charcoal, and mixtures thereof. The microporous breathable membrane 39 may be filled with about 50% to about 80%, or about 60% to about 80%, or about 70% to about 80%, or about 70% to about 75% silica by weight. The thickness of the breathable membrane 39 may be about 0.01 mm to about 1 mm, or between about 0.1 mm and 0.4 mm, or about 0.15 mm to about 0.35 mm, or about 0.25 mm.

[0058] Furthermore, the evaporation surface area of ​​the microporous, breathable membrane 39 can be approximately 2 cm². 2 Approximately 100cm2 or about 2cm 2 Approximately 25cm 2 or about 10cm 2 To approximately 50 2 or about 10cm 2 Approximately 45 2 Or about 10 2 Approximately 35cm 2 Or about 15cm 2 Approximately 40cm 2 Or about 15cm 2 Approximately 35cm 2 or about 20m 2 Approximately 35cm 2 Or about 30cm 2 Approximately 35cm 2 Or about 35cm 2 Therefore, the size and shape of the rear frame 200 can be designed to match the evaporation surface area of ​​the breathable membrane 39.
