Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a packaging container for holding 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 has a rather ordinary opening mechanism, which can easily lead to consumer fatigue and a poor user experience. Utility Model Content

[0004] This invention provides a packaging container for holding volatile substances, solving the problems of the conventional opening method and poor user experience of fragrance structures in existing technologies.

[0005] Packaging containers for holding volatile substances, including:

[0006] The outer tube has a first release port on its side wall and multiple circumferentially arranged slides on its inner 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] The pressing component is movably disposed at one end of the outer tube and is provided with multiple protruding teeth arranged circumferentially and cooperating with the slide rail.

[0010] The transmission component and the inner tube are provided with a transmission structure that allows the two to move axially relative to each other while restricting circumferential movement. The transmission component is provided with transmission teeth that cooperate with the slide rail and mesh with the convex teeth.

[0011] The elastic element has its two ends abutting against the transmission element and the inner tube, and is used to drive the transmission element to reset.

[0012] In use, the pressing member is moved axially, which drives the transmission member to move axially. After the transmission teeth disengage from the slide, the transmission member is driven to rotate circumferentially, thereby driving the inner tube to rotate synchronously, so that the first release port and the second release port are aligned or staggered, thereby opening or closing the channel.

[0013] 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.

[0014] Optionally, the first release port and the second release port are arranged in multiple groups, and the number of groups of the second release port is an integer multiple of the number of groups of the first release port.

[0015] Optionally, the axial heights of adjacent second release ports may differ.

[0016] Optionally, during multiple presses, the number of alignments between the first release port and the second release port increases or decreases sequentially.

[0017] 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.

[0018] Optionally, the bottom of the outer tube is provided with a retaining ring that engages with its side wall to prevent the inner tube from moving downward. The storage element passes through the retaining ring and is inserted into the inner tube, and the storage element engages with the retaining ring.

[0019] Optionally, the top of the retaining ring is provided with multiple protrusions, and under the action of the elastic element, the bottom of the inner tube body abuts against the protrusions.

[0020] Optionally, the bottom of the storage element is enlarged to form a barrier that restricts its further extension into the outer tube.

[0021] Optionally, the inner wall of the outer tube is provided with a plurality of protrusions arranged circumferentially, and a slide rail extending axially is formed between adjacent protrusions. The end of the protrusion has a guide slope to guide the transmission component to rotate into the next slide rail.

[0022] 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.

[0023] When the packaging container for volatile substances in this application needs to be opened for use, the pressing component is moved axially. After the transmission gear disengages from the slide, it drives the transmission component to rotate circumferentially. Under the action of the linkage mechanism, the inner tube rotates synchronously, so that the first release port and the second release port are aligned or staggered, thereby opening or closing the channel. This operation is not only simple and convenient, but also more interesting and enhances the consumer experience compared to the prior art. Attached Figure Description

[0045] See Figures 1-6One embodiment of this application provides a packaging container for holding volatile substances, including an outer tube 100, an inner tube 200, a storage element 300, a pressing element 400, a transmission element 500, and an elastic element 600.

[0046] The outer tube 100 has a first release port 110 on its side wall and a plurality of circumferentially arranged slides 130 on its inner wall. The number and shape of the first release ports 110 can be adapted to meet specific requirements. The inner tube 200 is rotatably mounted inside the outer tube 100 and has a second release port 210 on its side wall that corresponds to the first release port 110.

[0047] The storage element 300 is used to store volatile substances (such as fragrances), and is at least partially placed inside the inner tube 200. This part is provided with a third release port 310 that allows 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 310 are connected, the packaging container forms a channel for the volatile substances to escape outward.

[0048] The pressing element 400 is movably disposed at one end of the outer tube 100 and is provided with a plurality of protruding teeth 410 arranged circumferentially and cooperating with the slide rail 130. Preferably, the number of protruding teeth 410 corresponds to the number of slide rails 130.

[0049] A transmission structure is provided between the transmission component 500 and the inner tube 200, allowing axial relative movement while restricting circumferential movement. The transmission component 500 is provided with transmission teeth 510 that cooperate with the slide rail 130 and mesh with the protruding teeth 410. The inner tube 200, as shown in the figure, includes a first section 220 for accommodating the storage element 300 and a second section 230 with a reduced diameter relative to the first section 220 for cooperating with the transmission component 500. A second release port 210 is arranged in the first section 220. The transmission structure includes a positioning groove 520 disposed on the inner wall of the transmission component 500 and a positioning rib 231 located on the second section 230 that cooperates with the positioning groove 520. Preferably, the bottom of the positioning groove 520 and the top of the positioning rib 231 are angled to facilitate their insertion and engagement. Considering the stability of the structure during use, the number of transmission teeth 510 is multiple, for example, three are provided in this embodiment, and they are evenly arranged circumferentially.

[0050] The elastic element 600 abuts against the transmission element 500 and the inner tube 200 at both ends (the second section 230 is movably sleeved inside the transmission element 500) to drive the transmission element 500 to reset.

[0051] In use, the pressing component 400 is moved axially, which drives the transmission component 500 to move axially. After the transmission gear 510 disengages from the slide rail 130, the transmission component 500 is driven to rotate circumferentially. At this time, under the action of the transmission structure, the inner tube 200 is driven to rotate synchronously, so that the first release port 110 and the second release port 210 are aligned or staggered, thereby opening or closing the channel. Compared with the existing technology, the structure is novel, more interesting, and enhances the consumer experience.

[0052] In one embodiment, multiple sets of the first release port 110 and the second release port 210 are arranged, and the number of sets of the second release port 210 is an integer multiple of the number of sets of the first release port 110. Of course, the shape of the first release port 110 can be set according to requirements. For ease of explanation, in this embodiment, the first release port 110 is an axially extending strip structure, and correspondingly, the second release port 210 is also an axially arranged strip structure.

[0053] For easier understanding, please refer to Figures 1-4 In the following embodiments, the number of sets of the first release port 110 is 2, and they are arranged symmetrically.

[0054] In one embodiment, to achieve the alternating alignment and staggering of the first release port 110 and the second release port 210 during each press (channel opening or closing), for example, 12 slide rails 130 can be evenly arranged circumferentially on the inner wall of the outer tube 100. The inner tube 200 can rotate 30° during each press. Therefore, as long as a second release port 210 is provided every 60° in the inner tube 200, the alternating opening or closing effect of the channel between the inner tube 200 and the outer tube 100 can be achieved during each press. Of course, the number of slide rails 130 and the corresponding rotation angle of the inner tube 200 can be set according to requirements, as long as the function is achieved; this application does not impose any special requirements. For simplicity, unless otherwise specified, the following description assumes that 12 slide rails 130 are provided.

[0055] In another embodiment, in order to achieve the effect that the first release port 110 and the second release port 210 are aligned only when pressed twice (the channel is closed initially, the channel is also closed when pressed for the first time, and the channel is opened only when pressed for the second time), a second release port 210 can be provided in the inner tube 200 at every 90°; when it is necessary to achieve the effect that the first release port 110 and the second release port 210 are aligned only when pressed three times (the channel is closed initially, the channel is also closed when pressed for the first two times, and the channel is opened only when pressed for the third time), a second release port 210 can be provided in the inner tube 200 at every 120°.

[0056] In one embodiment, to achieve the channel's fully open, half-open, and closed states, such as Figure 7As shown, the axial heights of adjacent second release ports 210 are different. When the second release ports 210 with different axial heights correspond to the first release port 110, they can be fully opened or partially opened.

[0057] In another embodiment, to achieve the goal of increasing or decreasing the number of aligned groups of the first release port 110 and the second release port 210 during multiple presses, for example... Figure 8 As shown, there are 3 sets of first release ports 110, namely first release port 111a, first release port 112a and first release port 113a, which are arranged sequentially and spaced at an angle of 30°. There are 6 sets of second release ports 210, of which 3 sets correspond one-to-one with the 3 sets of first release ports, and the other 3 sets are arranged symmetrically. When it needs to be opened (initially the channel is closed), the first press rotates the inner tube 200 by 30 degrees, and volatile substances escape from the first release port 113a. The second press releases volatile substances from the first release ports 112a and 113a. The third press releases volatile substances from the first release ports 111a, 112a, and 113a. The same principle applies when it needs to be closed. Pressing down closes the channel connecting to the first release port 113a. Pressing again closes the channel connecting the first release ports 112a and 113a. Pressing again closes the channel connecting the first release ports 112a and 113a. Pressing again closes all channels.

[0058] Of course, other opening or closing effects can also be achieved by adjusting the corresponding rotation angles of the outer tube 100 and the inner tube 200, as well as the corresponding positions and shapes of the first release port 110 and the second release port 210. This application will not elaborate on them one by one.

[0059] See Figure 6 The inner wall of the outer tube 100 is provided with a plurality of protrusions 120 arranged circumferentially, and a slide 130 extending axially is formed between adjacent protrusions 120. The end of the protrusion 120 has a guide slope 121 for guiding the transmission member 500 to rotate into the next slide 130.

[0060] See Figure 9This is a schematic diagram showing the interaction of a transmission tooth 510, a protrusion 120, and a protrusion 410 during the axial movement of the pressing part 400 to its reset state. Specifically, a represents the initial state. At this time, the transmission tooth 510 abuts against the protruding tooth 410 within the slide rail 130. Due to the circumferential limiting effect of the slide rail 130, the transmission tooth 510 cannot rotate relative to the protruding tooth 410. When the pressing member 400 moves axially (see b), the protruding tooth 410 pushes against the transmission tooth 510 to move axially. Then, when the transmission tooth 510 continues to move axially until it disengages from the slide rail 130 (c), the circumferential direction is no longer restricted, and it can rotate relative to the protruding tooth 410 until it abuts against the root of the protruding tooth 410. Then, after the downward pressure is released, the pressing member 400 resets under the action of the elastic member 600. During this process, the protruding tooth 410 moves upward, and the top of the transmission tooth 510 abuts against the guide slope 121 of the protrusion 120. Then, the transmission tooth 510 rotates along the guide slope 121 into the next slide rail 130, thus completing one pressing operation.

[0061] See Figure 3 and Figure 6 The bottom of the outer tube 100 is open, and the storage element 300 is inserted into the outer tube 100 from the bottom and engages with it. A portion of the storage element 300 extends into the inner tube 200. Furthermore, the top of the outer tube 100 is open, and the pressing member 400 is axially movable and mounted on the top of the outer tube 100. To prevent the pressing member 400 from dislodging, the top has an inner flange 101 that engages with a tooth 410 to restrict the pressing member 400 from dislodging, wherein the protrusion 120 extends to the inner flange 101.

[0062] See Figures 3-6 The bottom of the outer tube 100 is provided with a retaining ring 140 that engages with its side wall to prevent the inner tube 200 from moving downward. The storage element 300 passes through the retaining ring 140 and is inserted into the inner tube 200. For example, as shown in the figure, a protruding ring 102 is provided on the inner peripheral wall of the outer tube 100, and a groove 142 is provided on the outer peripheral wall of the retaining ring 140. The two cooperate to achieve axial engagement. Of course, an interference fit or direct adhesive bonding can also be used for fixation, which will not be described further in this application.

[0063] The storage element 300 engages with the retaining ring 140, and the engagement structure can be, for example... Figure 3 and Figure 4 As shown, specifically, the storage element 300 is provided with a plurality of positioning blocks 340 arranged circumferentially, and the inner wall of the retaining ring 140 is provided with a retaining groove 143 that mates with the positioning blocks 340, and the two cooperate to achieve axial positioning. Of course, the positioning blocks 340 can also be connected to form a ring, which is not a special requirement in this application.

[0064] Under the action of the elastic element 600, the bottom end of the inner tube 200 abuts against the retaining ring 140, resulting in a large frictional force, which is not conducive to the rotation of the inner tube 200. To solve this problem, multiple protrusions 141 are arranged on the top of the retaining ring 140, and the bottom of the inner tube 200 abuts against the protrusions 141 to reduce the friction between it and the retaining ring 140. The number and length of the protrusions 141 can be adapted to meet the requirements.

[0065] The storage element 300 is a cylindrical structure with an open top and a closed bottom. A plug 330 is arranged at the open end to prevent leakage of volatile substances. The bottom widens to form a blocking portion 320 that restricts its further insertion into the outer tube 100 (simultaneously closing the bottom opening of the outer tube 100; its diameter is preferably larger than the diameter of the outer surface of the outer tube 100). After the volatile substances in the storage element 300 have evaporated, applying opposing forces to the outer tube 100 and the blocking portion 320 will disengage the positioning block 340 from the slot 143, allowing the storage element 300 to be smoothly pulled out from the bottom of the outer tube 100. Then, the plug 330 is opened to refill the volatile substances. Finally, the plug 330 is re-inserted, and the storage element 300 is inserted from the bottom of the outer tube 100 inwards until the positioning block 340 engages with the slot 143 to achieve axial positioning, thus completing the addition of volatile substances and making it more environmentally friendly.

[0066] 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.

[0067] 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.
