A fragrance monomer

Abstract

This invention discloses a fragrance monomer, comprising a container with an internal cavity and a cylindrical or pill-shaped shape, and a fragrance-dispersing substance disposed within the cavity for dispersing fragrance. The container includes a tube and a cap connected by a threaded seal or tightly fitted together, forming the cavity between the tube and the cap. The tube and / or the cap has a plurality of micropores with a pore size of 1 nanometer to 100 micrometers for the slow release of fragrance. Due to its structural characteristics, the fragrance monomer provided by this invention allows common fragrance raw materials and various functional fragrance raw materials to be presented in different physical forms (liquid / fluid / solid) within the fragrance monomer. This ensures that fragrance or functional raw material molecules can permeate and disperse outwards while limiting their permeation rate, achieving a longer-lasting and uniform release effect, thus improving service life. It is also compatible with in-vehicle fragrance systems of different car models with different fragrance dispersing methods, offering good applicability and versatility for various fragrance scenarios.

Description

Technical Field

[0001] This invention relates to the field of fragrance technology, specifically to a fragrance monomer. Background Technology

[0002] With the development of the automotive industry, there are not only higher requirements for technologies related to driving performance and environmental friendliness, but also for personalized needs during driving from the perspective of drivers and passengers (users). One such personalized need is to introduce a fragrance system into the cabin, so that users can enjoy the pleasure of driving in a space surrounded by fragrance.

[0003] The process of implementing the fragrance system is roughly as follows: a fragrance bottle containing a fragrance substance is installed (e.g., plugged in) into the vehicle's fragrance system. In this way, when the fragrance system is activated, the corresponding fragrance will diffuse throughout the vehicle's cabin.

[0004] However, existing fragrance bottle structures consist of a bottle body (fragrance holder) + fragrance carrier (fragrance-emitting substances adsorbed within the fragrance carrier). Fragrance dispersal typically relies on large holes in the bottle structure to allow air convection, thus dispersing the fragrance from the carrier. Consequently, current car fragrance systems primarily use solid fragrance carriers that absorb fragrance before dispersing it, such as diffuser sticks or perfume balms. This bottle structure cannot achieve a slow-release effect, significantly impacting its lifespan and user experience. Furthermore, existing car fragrance systems utilize both airflow and heat-based evaporation methods for fragrance dispersal. Different fragrance dispersing methods require different fragrance-generating substances in different states. For example, for air-blowing methods, solid fragrance carriers are preferred, although liquid and semi-gel forms are also acceptable. However, existing fragrance bottles that use liquid fragrance-generating substances are prone to leakage during use. Heating methods are generally used with liquid fragrance-generating substances. Therefore, when using these fragrance bottles as supplementary containers for car fragrance systems, they cannot be well adapted to different car fragrance systems with different dispersing methods in different car models. This poor applicability also limits the development of diverse fragrance functions and scenarios to some extent. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a fragrance monomer with optimized structural features. While ensuring that fragrance molecules (fragrance raw materials or functional raw material molecules) can permeate and diffuse outward, it can also limit their permeation rate, so as to achieve a longer period of uniform release and improve service life. It also offers a wider variety of fragrance types, making it compatible with in-vehicle fragrance systems with different fragrance dispersal methods in different car models. It has good applicability and can also meet the diverse needs of different users for fragrance scenarios.

[0006] To address the above problems, the present invention proposes the following technical solution:

[0007] In a first aspect, a fragrance monomer is provided, comprising a container having an internal cavity and being cylindrical or pill-shaped, and a fragrance-dispersing substance disposed within the cavity for dispersing fragrance. The container comprises a tube and a cap connected by a threaded seal or tightly fitted together, with the cavity formed between the tube and the cap. The tube and / or the cap have a plurality of micropores with a pore size of 1 nanometer to 100 micrometers for slowly releasing the fragrance emitted by the internal fragrance-dispersing substance, achieving the effect of fragrance permeability without liquid leakage.

[0008] Furthermore, both the tube body and the cap body are made of foamed PE integral injection molding. Both the tube body and the cap body have a number of micropores with a pore size of 1 nanometer to 100 micrometers. A PE microporous membrane or a TPU microporous membrane is provided between the inner wall of the cavity and the fragrance substance. The pore size of the PE microporous membrane or the TPU microporous membrane is 1-1000 nanometers.

[0009] Furthermore, both the tube body and the cap body are integrally injection molded from a mixture of polypropylene and mineral powder, with a weight percentage of 70:30 for the polypropylene and mineral powder. Both the tube body and the cap body have a number of micropores with a diameter of 10 nanometers to 100 micrometers. The mineral powder is selected from one or both of ultrafine calcium carbonate and calcium silicate.

[0010] Furthermore, both the tube body and the cap body are integrally injection molded from a mixture of polypropylene and EVA, with a weight percentage of 75:25 for polypropylene and EVA. Both the tube body and the cap body have a number of micropores with a diameter of 10 nanometers to 100 micrometers.

[0011] Furthermore, both the tube body and the cap body are integrally injection molded from a mixture of polypropylene and nylon, with a weight percentage of 80:20 for the polypropylene and nylon. Both the tube body and the cap body have a number of micropores with a diameter of 10 nanometers to 100 micrometers.

[0012] Furthermore, the fragrance-dispersing substance is a liquid fragrance oil, a semi-fluid fragrance gel, or a solid fragrance powder.

[0013] Furthermore, the fragrance oil is made by combining the antioxidant BHT with one or more of the following: rosemary essential oil, wild orange essential oil, lemon oil, peppermint oil, MMB / 3-methoxy-3-methyl-1-butanol, liquid paraffin, patchouli oil, sandalwood essential oil, tea tree essential oil, sweet orange oil, mustard oil, wintergreen oil, tea tree oil, clove oil, eucalyptus oil, thyme oil, bergamot oil, and juniper oil.

[0014] Furthermore, by weight percentage, the fragrance oil is made from the following raw material components: 14% rosemary essential oil, 14% wild orange essential oil, 14% lemon oil, 28% peppermint oil, 29.5% MMB / 3-methoxy-3-methyl-1-butanol, and 0.5% antioxidant BHT.

[0015] Furthermore, by weight percentage, the fragrance oil is made from the following raw material components: 21% patchouli oil, 19% sage oil, 23% tea tree oil, 11% peppermint oil, 25.5% sweet orange oil, and 0.5% antioxidant BHT.

[0016] Furthermore, by weight percentage, the fragrance oil is made from the following raw material components: 6% mustard oil, 6% wintergreen oil, 10% tea tree oil, 10% clove oil, 8% eucalyptus oil, 10% thyme oil, 10% rosemary oil, 10% bergamot oil, 10% juniper oil, 19.5% MMB / 3-methoxy-3-methyl-1-butanol, and 0.5% antioxidant BHT.

[0017] Furthermore, the fragrance gel is composed of a mixture of liquid fragrance oil and filler, wherein the weight percentage of fragrance oil to filler is 94:6; the filler is selected from one or more of fumed silica, calcium carbonate, talc and mica powder.

[0018] Furthermore, the fragrance gel is composed of a mixture of liquid fragrance oil and polymeric resin gel, wherein the weight percentage of the fragrance oil to the polymeric resin gel is 89:11; the polymeric resin gel is preferably SEBS.

[0019] Furthermore, the fragrance powder is composed of a mixture of liquid fragrance oil and adsorbent material, wherein the weight percentage of fragrance oil to adsorbent material is 75:25, and the adsorbent material is selected from one or more of calcium silicate, calcium oxide, and oak powder.

[0020] Furthermore, the adsorbent material is composed of calcium silicate, calcium oxide and oak powder mixed in a weight ratio of 1:1:1.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The tube and / or cap of the present invention have a number of micropores with a pore size of 1 nanometer to 100 micrometers, so that the container containing the fragrance substance can simultaneously meet the requirements of sealing and fragrance permeability, that is, fragrance permeability without liquid leakage. Thus, the container can slowly release the fragrance emitted by the internal fragrance to the outside, and while ensuring that the fragrance or functional raw material molecules can pass through and be emitted to the outside, it can also limit their permeation rate, so as to achieve the effect of uniform release over a longer period of time and improve the service life.

[0023] 2. Secondly, by utilizing the characteristics of the container, it can hold liquid, semi-fluid, or solid fragrance substances without leakage. This allows the fragrance monomer to be adapted to different car fragrance systems with different fragrance dispersal methods in different car models, depending on the state of the contents. The state of the fragrance substance in the fragrance monomer can also be selected according to different usage scenarios and user needs, making it highly adaptable.

[0024] 3. The fragrance oil in this invention can be a single synthetic or natural essential oil, or it can be a blend of various essential oils to create a mixed fragrance oil with different functions: for example, a fragrance oil blended with peppermint oil, rosemary oil, and peppermint oil has the functions of long-lasting fragrance and refreshing the mind; or a fragrance oil blended with peppermint oil and citrus essential oil has the functions of long-lasting fragrance and preventing motion sickness; and a fragrance oil blended with eucalyptus oil, thyme oil, juniper oil, bergamot oil, rosemary oil, clove oil, tea tree oil, wintergreen oil, and mustard oil has the functions of long-lasting fragrance and antibacterial and deodorizing functions. This achieves functional diversification, making the functions more diverse and efficient. The fragrance single oil not only has the effect of fragrance, but also includes the functions of refreshing the mind, preventing motion sickness, or antibacterial and deodorizing, thus improving the practicality and added value of the product.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0034] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0035] Example 1

[0036] like Figures 1 to 2 As shown, the fragrance monomer provided in this embodiment includes a container 1 with an internal cavity and a cylindrical shape, and a fragrance-dispersing substance 2 disposed in the cavity for dispersing fragrance. The container 1 includes a tube 10 and a cap 11 connected by a threaded seal. A cavity is formed between the tube 10 and the cap 11. The tube 10 and / or the cap 11 are densely covered with a number of micropores with a pore size of 1 nanometer to 100 micrometers to slowly release the fragrance emitted by the internal fragrance-dispersing substance and achieve the effect of permeable fragrance without leakage.

[0037] Understandably, container 1 could also be designed as a pill (e.g., ...). Figure 3 (As shown).

[0038] It is understandable that the tube body 10 and the cover body 11 can also be connected by a tight fit (e.g., Figure 4 (As shown).

[0039] As described above, the tube and / or cap have several micropores with a diameter of 1 nanometer to 100 micrometers, allowing the container holding the fragrance substance to simultaneously meet the requirements of sealing and fragrance permeability. This allows the container to slowly release the fragrance emitted by the internal fragrance, ensuring that the fragrance or functional raw material molecules can permeate while limiting their permeation rate, achieving a longer-term, uniform release effect and improving its service life. Secondly, utilizing the characteristics of this container, it can hold liquid, semi-fluid, or solid fragrance substances without leakage. This allows the fragrance monomer to be adapted to different car fragrance systems with different fragrance dispersing methods in different vehicle models, and the state of the fragrance substance within the fragrance monomer can be selected according to different usage scenarios and user needs, demonstrating good applicability.

[0040] In one embodiment, in order to form micropores on both the tube body 10 and the cap body 11, both the tube body 10 and the cap body 11 are integrally injection molded from foamed PE. Utilizing the material properties of foamed PE, both the tube body 10 and the cap body 11 have a number of micropores with a pore size of 1 nanometer to 100 micrometers. A microporous membrane 12 is provided between the inner wall of the cavity and the fragrance substance. The pore size of the microporous membrane 12 is 1-1000 nanometers. That is, the microporous membrane 12 is also densely covered with a number of micropores with a pore size of 1-1000 nanometers. The pore size of the micropores on the microporous membrane is smaller than that on the tube body and the cap body, forming a pore structure with a smaller inner pore and a larger outer pore, which can better achieve the slow release effect of the fragrance substance inside.

[0041] In some alternative embodiments, the microporous membrane is a PE microporous membrane or a TPU microporous membrane.

[0042] In one embodiment, such as Figure 2 or Figure 4 As shown, the microporous membrane 12 is sealed and wrapped around the fragrance substance 2 to form a sealed bag shape; that is, after the fragrance substance is put into the microporous membrane, it is sealed to form a sealed bag, and then the sealed bag is put into the cavity. This method makes it convenient for the microporous membrane 00 to be placed between the inner wall of the cavity and the fragrance substance, and also facilitates production.

[0043] In another alternative embodiment, such as Figure 5 As shown, microporous membranes 12 can be provided on the inner wall of the tube body 10 and the inner top surface of the cover body 11 by means of bonding. After the cover body and the tube body are assembled and connected, the microporous membrane on the inner top surface of the cover body is pressed by the top of the tube body, so that the microporous membrane between the two forms a sealed membrane bag structure, thereby sealing the fragrance substance 2 inside the microporous membrane, and it can only release fragrance slowly outward through the micropores on the microporous membrane.

[0044] In one embodiment, the fragrance substance 2 is a liquid fragrance oil, a semi-fluid fragrance gel, or a solid fragrance powder. When it is solid, it is generally not made into a monolithic shape, but rather into a solid powder, so that the fragrance substance can be conveniently put into the cavity for use in any of these states.

[0045] Optionally, when the fragrance substance is a semi-fluid fragrance gel, the fragrance gel is made by mixing liquid fragrance oil and filler, and the filler is used to thicken the fragrance oil to make it semi-fluid. The weight percentage of fragrance oil to filler is 94:6. The filler is selected from one or more of fumed silica, calcium carbonate, talc and mica powder, preferably fumed silica, that is, the semi-fluid fragrance gel is made by mixing liquid fragrance oil and fumed silica.

[0046] In another approach, when the fragrance substance is a semi-fluid fragrance gel, the fragrance gel can also be made by mixing liquid fragrance oil and polymer resin gel. The polymer resin gel is used to thicken the fragrance oil, making it semi-fluid. The weight percentage of fragrance oil to polymer resin gel is 89:11. The polymer resin gel is preferably SEBS.

[0047] Optionally, when the fragrance-dispersing substance is a solid fragrance powder, the fragrance powder is made by mixing liquid fragrance oil with an adsorbent material, that is, the fragrance oil is adsorbed by the adsorbent material and then dispersed. The weight percentage of fragrance oil to adsorbent material is 75:25, and the adsorbent material is selected from one or more of calcium silicate, calcium oxide and oak powder. Preferably, the adsorbent material is made by mixing calcium silicate, calcium oxide and oak powder in a weight ratio of 1:1:1.

[0048] In one embodiment, the fragrance oil may be a single synthetic or natural essential oil, including but not limited to rosemary essential oil, wild orange essential oil, lemon oil, peppermint oil, MMB / 3-methoxy-3-methyl-1-butanol, liquid paraffin, patchouli oil, sandalwood essential oil, tea tree essential oil, sweet orange oil, mustard oil, wintergreen oil, tea tree oil, clove oil, eucalyptus oil, thyme oil, bergamot oil, or juniper oil.

[0049] In one embodiment, a small amount of antioxidant BHT may be added to the fragrance oil to prevent the fragrance oil from oxidizing and deteriorating; preferably, the weight percentage of fragrance oil to antioxidant BHT is 99.5:0.5.

The weight percentage of polypropylene and mineral powder is 70:30. Both the tube and the cap have a number of micropores with a diameter of 10 nanometers to 100 micrometers.

[0052] The mineral powder is selected from one or both of ultrafine calcium carbonate and calcium silicate. When a mixture of ultrafine calcium carbonate and calcium silicate is used, the ultrafine calcium carbonate and calcium silicate are mixed in a weight ratio of 1:1.

[0053] Optionally, the polypropylene used is SK-J300 type.
