[0041] Liquid perfumes on the market are primarily contained in sealed containers, which are sealed by sequentially stacking a sealing tear sheet 300 and a diffusion membrane 400. During use, the sealing tear sheet 300 is broken to open the container opening, allowing the perfume inside to evaporate through the diffusion membrane 400. Currently, container openings are typically opened using puncture with a piercing member or external pressure. Both methods can easily damage the diffusion membrane 400, causing perfume to overflow. The present invention therefore proposes a tear-open perfume diffuser container 100 that avoids damage to the diffusion membrane 400 when the sealing tear sheet 300 is torn, resulting in perfume overflow.

[0042] like Figure 1 and 2 As shown, the fragrance diffusion container 100 according to the embodiment of the present invention includes a container shell 200 , a sealing tear sheet 300 and a diffusion membrane 400 .

[0043] The container shell 200 of this embodiment is provided with a cavity groove 210 for holding perfume. The cavity groove 210 is provided with a notch 211 opening facing upward. In other embodiments, the notch 211 of the cavity groove 210 can be set to face downward, left, right, front or rear. In order to facilitate the description of other components, this embodiment is described as an example in which the notch 211 of the cavity groove 210 faces upward. In actual use, the container shell 200 is placed upright, and the notch 211 of the cavity groove 210 is set to face sideways.

[0044] The container shell 200 of this embodiment is formed by vacuum molding, and the container shell 200 is in the shape of a box. The container shell 200 has a certain elastic deformation function. In other embodiments, the container shell 200 can be made of other materials, or can be formed by stamping, injection molding, hot pressing, etc., which are not given examples here.

[0045] The tear-off sealing sheet 300 of this embodiment is used to seal the sealing notch 211. The tear-off sealing sheet 300 is made of an easily tearable material. Specifically, the tear-off sealing sheet 300 of this embodiment is made of easily tearable aluminum foil. The tear-off sealing sheet 300 is sealedly disposed in the notch 211. The tear-off sealing sheet 300 is sealedly connected to the edges around the notch 211. The tear-off sealing sheet 300 and the cavity groove 210 form a storage cavity for storing perfume.

[0046] The diffusion membrane 400 is used for the volatilization and diffusion of perfume. The diffusion membrane 400 can be waterproof and breathable. The diffusion membrane 400 of this embodiment adopts a waterproof and breathable membrane, and the diffusion membrane 400 is a membrane structure with a certain elastic deformation. In some other embodiments, the diffusion membrane 400 can adopt other waterproof and breathable membrane structures.

[0047] The diffusion membrane 400 of this embodiment is also sealed in the notch 211 . The diffusion membrane 400 is sealed to the edge of the notch 211 . The sealing tear sheet 300 and the diffusion membrane 400 are arranged inside and outside. The diffusion membrane 400 of this embodiment overlaps the outside of the sealing tear sheet 300 .

[0048] In this embodiment, inner and outer stepped surfaces 212 and 213 are provided around the edges of the notch 211. The inner and outer stepped surfaces 212 and 213 are spaced apart along the depth direction of the cavity 210. The edge of the diffusion membrane 400 is sealed to the outer stepped surface 213, and the edge of the sealing tear sheet 300 is sealed to the inner stepped surface 212.

[0049] The inner step surface 212 and the outer step surface 213 of this embodiment can facilitate the sealed connection between the diffusion membrane 400 and the sealing tear sheet 300, and can also form a gap between the diffusion membrane 400 and the sealing tear sheet 300. When pressing the outer diffusion membrane 400, the sealing tear sheet 300 is not directly pressed. The diffusion membrane 400 needs to be pressed to a certain extent before it can come into contact with the sealing tear sheet 300. At this time, continued pressing is required to press the sealing tear sheet 300, thereby preventing accidental contact. The gap is determined by the height difference between the inner step surface 212 and the outer step surface 213.

[0050] During production and processing, perfume is added into the cavity groove 210 in advance, and then the sealing tear sheet 300 is used to seal the groove 211, and then the diffusion membrane 400 is covered on the groove 211 to form a diffusion container filled with perfume.

[0051] In this embodiment, at least one tearing limit platform 214 is protruded from the bottom of the cavity groove 210. The tearing limit platform 214 is arranged in the same direction as the groove opening 211. In some embodiments, multiple tearing limit platforms 214 can be set according to the demand for diffusion amount. In this embodiment, one tearing limit platform 214 is set.

[0052] In this embodiment, the bottom of the tear-stop platform 214 is flexibly connected to the bottom of the cavity groove 210, so that the tear-stop platform 214 can move relative to the container shell 200. It can be understood that under the action of an external force, the top of the tear-stop platform 214 can move relative to the container shell 200, wherein the top of the tear-stop platform 214 can move in the depth direction or swing left and right. The tear-stop platform 214 is deflected by the external force, prompting the sealing tear sheet 300 to be torn open. In this embodiment, the top of the tear-stop platform 214 is limited to move toward the bottom of the container shell 200.

[0053] The bottom surface of the sealing tear sheet 300 is provided with at least one fitting tearing area 310, which corresponds to the position of the tearing limit platform 214, and the top surface of the tearing limit platform 214 is connected and fixed to the fitting tearing area 310. In some embodiments, the top surface of the tearing limit platform 214 and the fitting tearing area 310 can be fixed by gluing, or by laser welding or heat sealing.

[0054] Furthermore, the bottom surface of the sealing and tearing sheet 300 and the top surface of the tearing limit platform 214 are in the same plane. In a natural state, the tearing area 310 and other parts of the sealing and tearing sheet 300 are coplanar.

[0055] When the perfume diffusion container 100 needs to be opened for fragrance diffusion, under the action of external force, the tear limit platform 214 is pressed or pulled to move relative to the container shell 200 to drive the fitting tear area 310 to move, so that the sealing tear sheet 300 around the fitting tear area 310 is torn to form a tear hole. The perfume passes through the tear hole of the sealing tear sheet 300 and evaporates outward through the diffusion membrane 400. The present application uses the tear limit platform 214 to drive the fitting tear area 310 on the sealing tear sheet 300 to move, so as to tear and open the sealing tear sheet 300, which can effectively reduce the risk of damaging the diffusion membrane 400 and causing the perfume to overflow.

[0056] In order to further avoid damage to the diffusion membrane 400, this embodiment can press or pull the tear limit platform 214 downward in the depth direction to move the bonding tear area 310 downward. When external force acts on the tear limit platform 214, the stress is concentrated on the bonding tear area 310. At this time, under the action of the sealed connection between the sealing tear sheet 300 and the edge of the slot 211, a tear is torn between the bonding tear area 310 and the sealing tear sheet 300.

[0057] In addition, the tear limit platform 214 of the present embodiment not only plays the role of tearing the bonding tearing area 310, but also limits the tearing movement of the bonding tearing area 310. When the external force acts on the top of the tear limit platform 214 from top to bottom through the diffusion film 400 and the sealing tearing sheet 300, that is, pressing the tear limit platform 214 downward, the bonding tearing area 310 can also be moved downward. At this time, due to the support of the tear limit platform 214, the pressing stroke is limited. It can be understood that the tear limit platform 214 cannot be pressed down infinitely. If the tear limit platform 214 is pressed down too deep, the diffusion film 400 is easily pressed down to the critical point of tearing.

[0058] The number of the cavities 210 can be one or more. When multiple cavities 210 are provided, each cavity 210 can store perfumes of different scents. When in use, the tearing limit platform 214 in different cavities 210 can be pressed or pulled to achieve different scent mixing.

[0059] In order to make the sealing tear sheet 300 easier to tear, the sealing tear sheet 300 of this embodiment is provided with a tear tape 320. The tear tape 320 is arranged around the bonding tear area 310. The tear tape 320 is formed by laser removal of the PE film. The tear tape 320 is easier to tear than the area of ​​the sealing tear sheet 300. When the sealing tear sheet 300 is torn, it is torn at the tear tape 320 to form a tearing hole.

[0060] The tear tape 320 is a thin sheet structure that is easy to tear. In some embodiments, the tear tape 320 is a tear pattern structure designed by laser or other processes to induce tearing.

[0061] When the tearing limit platform 214 is driven to move downward in the depth direction by pulling, in order to facilitate the application of external force, the bottom of the tearing limit platform 214 of this embodiment is provided with a tearing groove 215 that is concave inward from the bottom of the container shell 200, and the tearing groove 215 is provided with a clamping portion 216. When in use, the external pulling component extends into the tearing groove 215 and is clamped with the clamping portion 216 to realize the connection between the external pulling component and the top of the tearing limit platform 214. At this time, the tearing limit platform 214 can be pulled downward.

[0062] The tearing limit platform 214 of this embodiment is integrally formed with the cavity groove 210. It can be understood that the tearing limit platform 214 and the container shell 200 are integrally formed by PET blister molding. When the container shell 200 is produced, the tearing limit platform 214 and the cavity groove 210 can be integrally processed and formed, thereby simplifying the production process.

[0063] In this embodiment, an elastic connector 217 is provided between the bottom of the tearing limit platform 214 and the bottom of the cavity groove 210 , and the elastic deformation of the elastic connector 217 enables the tearing limit platform 214 to move freely under the action of external force.

[0064] Due to its molding method, the elastic connector 217 of this embodiment is annular and has an arcuate cross-section. The elastic connector 217 allows for free movement of the tear-stopping platform 214 in the depth direction. The elastic connector 217 also has an elastic force for easy operation. The elastic deformation of the elastic connector 217 also limits the movement of the tear-stopping platform 214.

[0065] In addition, the outer diameter of the tearing limit platform 214 is gradually increased from the top to the bottom along the depth direction, which can improve the structural strength of the tearing limit platform 214, avoid the tearing limit platform 214 from tilting, and facilitate injection molding and demolding.

[0066] Furthermore, the container shell 200 is provided with at least one diffusion step portion 218 extending outward at the edge of the slot 211, and the cavity slot 210 includes a main slot 220 and a diffusion slot 230. A number of flow slots 240 are connected between the main slot 220 and the diffusion slot 230. The diffusion slot 230 is provided in the middle of the diffusion step portion 218, and the bottom surface of the sealing tear sheet 300 is connected and fixed to the top surface of the diffusion step portion 218. The tear limit platform 214 is provided in the middle of the diffusion slot 230. It can be understood that the top surface of the diffusion step portion 218 and the inner step surface 212 are on the same plane, so that the sealing tear sheets 300 around the diffusion slot 230 are all fixed. When the tear limit platform 214 moves, the tearing stress acts on the four sides of the fitting tear area 310, and the collar sealing tear sheet 300 is more easily torn.

[0067] In this embodiment, the main groove 220 is mainly used to store perfume, while the diffusion groove 230 is mainly used for volatilization of perfume. The tear limit platform 214 set in the diffusion groove 230 corresponds to the fitting tear area 310 on the sealing tear sheet 300. As the volatilization time progresses, the perfume in the main groove 220 will evaporate outward along the circulation groove 240, the diffusion groove 230, and the diffusion membrane 400.

[0068] like Figure 2 As shown, the bottom of the container shell 200 facing away from the notch 211 is provided with a placement bottom surface 250, and a hollow area 260 is formed between the bottom of the diffusion step portion 218 and the plane where the placement bottom surface 250 is located, so that a height difference is formed between the diffusion groove 230 and the main groove 220. This creates a channel for the perfume to evaporate or pass through, and is also conducive to the formation of the tear limit platform 214, and provides space for the installation of external pulling components.

[0069] The utility model also provides a perfume diffusion device, such as Figures 3 to 6 As shown, the perfume diffusion device includes the above-mentioned perfume diffusion container 100, a housing 500 and an elastic pressing member. The perfume diffusion container 100 is installed in the housing 500. The elastic pressing member is provided with an actuating portion 600 corresponding to the top position of the tear limit platform 214. The actuating portion 600 is configured to drive the tear limit platform 214 to move when the elastic pressing member is pressed, so as to tear the sealing tear sheet 300.

[0070] Among them, the elastic pressing piece is provided with a connecting end and an operating end, the connecting end is connected to the inside of the housing 500, and the operating end can swing freely, and the actuating part 600 is arranged between the connecting end and the operating end. When in use, by pressing the operating end, the elastic pressing piece is driven to swing, thereby driving the actuating part 600 to move. Under the action of the actuating part 600, the tearing limit platform 214 moves along the depth direction to tear the sealing tearing sheet 300.

[0071] Regarding the position of the actuating portion 600, the present invention proposes two embodiments:

[0072] like Figure 3 and Figure 4 As shown, Example 1:

[0073] In this embodiment, a first elastic pressing member 700 is provided within the housing 500 and is located on the bottom side of the fragrance diffuser container 100. The actuating portion 600 is provided on the bottom side of the container shell 200. The actuating portion 600 is connected to the tear-limiting platform 214 via the bottom surface of the container shell 200. It can be understood that the actuating portion 600 at this time extends into the tear groove 215 and engages with the engaging portion 216 to achieve connection between the actuating portion 600 and the top of the tear-limiting platform 214. When the operating end is pressed downward, the tear-limiting platform 214 is pulled downward by the actuating portion 600.

[0074] In some other embodiments, the actuating portion 600 may also act on the tearing limit platform 214 by gluing, suction cup adsorption, or the like.

[0075] like Figure 5 and Figure 6 As shown, Example 2:

[0076] In this embodiment, a second elastic pressing member 800 is provided in the housing 500 and is located on the top side of the perfume diffuser container 100. The actuating portion 600 is provided on the top side of the container shell 200. The actuating portion 600 abuts against the top of the tear-limiting platform 214 through the diffusion membrane 400 and the sealing tear sheet 300. It can be understood that the actuating portion 600 is located on the upper side of the diffusion membrane 400. When the operating end is pressed downward, the top of the tear-limiting platform 214 is pressed downward by the actuating portion 600. At this time, the downward stroke of the tear-limiting platform 214 is less than the critical deformation stroke that causes the diffusion membrane 400 to be destroyed.

[0077] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
