Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a packaging container for volatile substances. Background Technology

[0002] The conventional fragrance structures on the market are generally open-top or rotating types. For example, a fragrance box disclosed in announcement number CN213852259U includes a box body and a lid. The lid includes a lid body that is sealed and detachably connected to the box body, and a baffle set in the lid body that can rotate relative to the lid body. The baffle has several fragrance diffusion areas, and the lid body has several fragrance diffusion holes. When the lid body and the baffle rotate relative to each other, the fragrance diffusion holes correspond to the fragrance diffusion areas or are staggered so that the lid body can partially or completely block the fragrance diffusion areas.

[0003] However, this type of fragrance structure is rather ordinary and lacks interest, which can easily lead to consumer fatigue and a poor experience. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a packaging container for volatile substances.

[0005] Packaging containers for volatile substances include:

[0006] The outer tube body has a first release port on its side wall;

[0007] The inner tube is rotatably mounted inside the outer tube, and its side wall has a second release port corresponding to the first release port.

[0008] A storage element for storing the volatile substance is at least partially placed inside the inner tube, and this part is provided with a third release port. When the first release port, the second release port and the third release port are connected, the packaging container forms a channel for the volatile substance to escape outward.

[0009] A driving component is movably mounted on the outer tube body, and a linkage mechanism is provided between the driving component and the inner tube body; when the driving component is manipulated to move, the inner tube body can be driven to rotate, thereby aligning or offsetting the first release port and the second release port, thereby opening or closing the channel.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] Optionally, the bottom of the outer tube is open, the storage element is inserted into the outer tube from the bottom and engages with the outer tube, and a portion of the storage element extends into the inner tube.

[0012] Optionally, the bottom of the storage element is enlarged to form a barrier that restricts its further extension into the outer tube.

[0013] Optionally, the bottom of the outer tube is provided with a retaining ring that is interference-fitted with its side wall to prevent the inner tube from moving downward, and the storage element is inserted into the inner tube after passing through the retaining ring.

[0014] Optionally, the storage element engages with the retaining ring.

[0015] Optionally, the inner wall of the outer tube has a limiting step, and the inner tube has a radially protruding limiting part, which is placed between the limiting step and the retaining ring, thereby restricting the axial movement of the inner tube.

[0016] Optionally, the storage element is a cylindrical structure that is open at the top and closed at the bottom, with a plug at the open end to prevent leakage of volatile substances.

[0017] Optionally, the top of the outer tube is open, and the drive component is axially movable and mounted on the top of the outer tube.

[0018] Optionally, the drive member has an inner plug portion that inserts into the outer tube and an operating portion that extends to the outside of the outer tube. Correspondingly, the top end of the outer tube has a clearance groove to allow the operating portion to move downward. In the initial state, the operating portion covers the clearance groove, and the drive member is flush with the top surface of the outer tube.

[0019] Optionally, the linkage mechanism includes a spiral groove disposed on one of the driving member and the inner tube body, and a protrusion disposed on the other that cooperates with the spiral groove.

[0020] When the packaging container for volatile substances in this application needs to be opened for use, the driving component is moved by manipulating it. Due to the action of the linkage mechanism, the inner tube will rotate accordingly, so that the first release port and the second release port are aligned. At this time, the volatile substance can evaporate outward from the channel. This operation is not only simple and convenient, but also more interesting and enhances the consumer experience compared to packaging tubes that are rotated or opened. Attached Figure Description

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a system, product, or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.

[0038] See Figures 1 to 7 One embodiment of this application provides a packaging container for volatile substances, including an outer tube 100, an inner tube 200, a drive element 300, and a storage element 400.

[0039] For ease of explanation, the terms "top" and "bottom" will be used in the following text. Figure 1 The posture in the middle is used as a reference.

[0040] The outer tube 100 has a first release port 110 on its side wall. The number and shape of the first release ports 110 can be adapted to meet the requirements. Preferably, there are multiple first release ports 110. The inner tube 200 is rotatably mounted inside the outer tube 100, and its side wall has a second release port 210 corresponding to the first release port 110. Correspondingly, there are also multiple second release ports 210.

[0041] The storage element 400 is used to store volatile substances (e.g., fragrances), and is at least partially located inside the inner tube 200 (this part is the main body 410), and this part is provided with a third release port 411 that allows the volatile substances to escape into the inner tube 200. When the first release port 110, the second release port 210 and the third release port 411 are connected, the packaging container forms a channel for the volatile substances to escape outward.

[0042] The driving component 300 is movably mounted on the top of the outer tube 100. A linkage mechanism is provided between the driving component 300 and the inner tube 200. For example, the linkage mechanism includes a spiral groove 310 provided on one of the driving component 300 and the inner tube 200, and a protrusion 220 provided on the other that cooperates with the spiral groove 310. In the figure, the spiral groove 310 is provided on the driving component 300, and the protrusion 220 is provided on the inner tube 200. Considering the stability during rotation, there are two protrusions 220 and two corresponding spiral grooves 310, which are symmetrically arranged. When the driving component 300 is moved (specifically in the height direction in the figure), the inner tube 200 can be driven to rotate, thereby aligning or offsetting the first release port 110 and the second release port 210, thereby opening or closing the channel.

[0043] When air quality needs to be improved, the drive unit 300 is moved to rotate the inner tube 200, aligning the first release port 110 and the second release port 210. At this time, volatile substances can evaporate outward from the channel. This operation is not only simple and convenient, but also more interesting and enhances the consumer experience compared to packaging tubes that require rotation or opening.

[0044] In one embodiment, the bottom of the outer tube 100 is open, and the storage element 400 is inserted into the outer tube 100 from the bottom and engages with it. A portion of the storage element 400 extends into the inner tube 200. Furthermore, the top of the outer tube 100 is open, and the drive member 300 is axially movably mounted on the top of the outer tube 100. See also... Figure 3 The top end of the inner tube 200 is a closed structure, and the protrusion 220 is disposed in this closed structure. In order to cooperate with the drive member 300, the closed structure is reduced in diameter compared with the inner tube 200 so that it can extend into the drive member 300, allowing the protrusion 220 to cooperate with the spiral groove 310. Furthermore, since the inner tube 200 of this application is inserted and assembled from the bottom of the outer tube 100, in order to facilitate the protrusion 220 to extend into the spiral groove 310, an axial extension section 330 is also arranged at the bottom of the spiral groove 310.

[0045] See Figures 3-4 The bottom of the outer tube 100 is provided with a retaining ring 120 that is interference-fitted with its side wall to prevent the inner tube 200 from moving downward. The storage element 400 passes through the retaining ring 120 and is inserted into the inner tube 200. In this embodiment, a plurality of axially arranged positioning ribs 122 are provided on the outer peripheral wall of the retaining ring 120. The side wall of the outer tube 100 and the positioning ribs 122 are interference-fitted to achieve a fixed connection between the two. Of course, other structures can also be used to achieve the interference fit or to fix it directly by adhesive, which will not be described in this application.

[0046] Furthermore, the storage element 400 engages with the retaining ring 120, and the engagement structure can be, for example... Figure 3 and Figure 7 As shown, specifically, the storage element 400 has a connecting part 420, on which an annular protrusion 421 is provided. The inner wall of the retaining ring 120 is provided with a positioning groove 121 that cooperates with the annular protrusion 421. The two cooperate to achieve axial positioning.

[0047] See Figures 3-6 The inner wall of the outer tube 100 has a limiting step 130, and the inner tube 200 has a radially protruding limiting part 250. The limiting part 250 is placed between the limiting step 130 and the retaining ring 120, thereby restricting the axial movement of the inner tube 200. Of course, in order to reduce the friction between the inner tube 200 and the retaining ring 120 when the inner tube 200 rotates, the bottom of the inner tube 200 is provided with a plurality of circumferentially arranged protrusions 240. In the figure, there are 3 protrusions 240, which are evenly arranged circumferentially.

[0048] In one embodiment, the outer wall of the inner tube 200 is provided with a protrusion 230 that fits with the inner wall of the outer tube 100 with a clearance. The protrusion 230 can reduce the friction between the inner tube 200 and the inner wall of the outer tube 100 when the inner tube 200 rotates, and can also reduce shaking. Preferably, the protrusion 230 is an annular structure, and multiple protrusions are provided. For example, in the figure, there are two protrusions 230, which are respectively provided at the top and the bottom.

[0049] See Figure 3 and Figure 7 The storage element 400 is a cylindrical structure with an open top and a closed bottom. A plug 430 is arranged at the open end to prevent leakage of volatile substances. The bottom widens to form a blocking portion 440 that restricts its further insertion into the outer tube 100 (simultaneously closing the bottom opening of the outer tube 100; its diameter is greater than or equal to the outer surface of the outer tube 100). After the volatile substances in the storage element 400 have evaporated, only opposite forces need to be applied to the outer tube 100 and the storage element 400 (blocking portion 440). The annular protrusion 421 will disengage from the positioning groove 121, allowing the storage element 400 to be smoothly pulled out from the bottom of the outer tube 100. Then, the plug 430 can be opened to refill the volatile substances. Finally, the plug 430 is re-inserted, and the storage element 400 is inserted from the bottom of the outer tube 100 inwards until the annular protrusion 421 engages with the positioning groove 121 of the retaining ring 120 to achieve axial restraint, thus completing the addition of volatile substances, making it more environmentally friendly.

[0050] In order to make the driving component 300 move in a predetermined direction, a guide groove 320 is axially arranged on the driving component 300, and a positioning block 140 that cooperates with the guide groove 320 is provided on the inner wall of the outer tube 100. Furthermore, a locking block 321 is provided at the bottom of the guide groove 320 to prevent the driving component 300 from coming out.

[0051] In the initial state where the first release port 110 and the second release port 210 are staggered, the drive component 300 is flush with the top surface of the outer tube 100, making the overall appearance more aesthetically pleasing.

[0052] See Figure 6 The drive member 300 has an inner plug portion 350 that inserts into the outer tube body 100 and an operating portion 340 that extends to the outside of the outer tube body 100. Correspondingly, the top end of the outer tube body 100 has a clearance groove 150 that avoids the downward movement of the operating portion 340. In the initial state, the operating portion 340 covers the clearance groove 150. Preferably, there are two operating portions 340 and corresponding clearance grooves 150, and they are arranged symmetrically.

[0053] When using the volatile substance packaging container of this application, pressing down on the operating part 340 causes the protrusion 220 to rotate along the spiral groove 310, which in turn drives the inner tube 200 to rotate. The first release port 110 and the second release port 210 are aligned, allowing the volatile substance to be released. To close the container, the operating part 340 is pushed upwards, causing the inner tube 200 to rotate and the first release port 110 and the second release port 210 to be misaligned, thus achieving closure.

[0054] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0055] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
