Description

Technical Field

[0001] The present invention relates to the structure of a long-term cooling analgesic ointment with a discoloration indication function, and particularly to an analgesic ointment that exhibits different color changes according to the skin temperature rise and skin tension.

Background Art

[0002] Many commercially available analgesic ointments are white or transparent and form a transparent thin film when applied to the skin. As a result, it is difficult for users to immediately determine whether the analgesic ointment has already been applied to the affected area or whether the application range uniformly covers the affected area. Consequently, subsequent auxiliary treatments such as massage and acupressure may have difficulty accurately targeting the affected area, and a sufficient analgesic effect may not be obtained in some cases.

[0003] In view of the drawbacks of the above-mentioned known structures, the present invention has noticed its incomplete points. Many commercially available analgesic ointments are highly viscous and lack permeability. Not only do they cause discomfort to the skin after application, but it is also difficult for the medicinal components to sufficiently penetrate into the affected area, resulting in a limited problem in alleviating pain and stiffness.

[Figure 7] This is a schematic diagram of the analgesic ointment of the present invention after it has been applied to the skin. [Modes for carrying out the invention]

[0009] Referring to Figures 1 to 3, the present invention is a long-lasting cooling analgesic ointment structure 100 with a color-changing function, comprising a soft shell body 10 and an analgesic ointment 20. The soft shell body 10 is not limited to a plastic material and is deformable by external force. Furthermore, the soft shell body 10 has a housing space S and an outlet 11 communicating with the housing space S. The analgesic ointment 20 is placed in the housing space S of the soft shell body 10, and by pressing the soft shell body 10 with an external force to deform it, the analgesic ointment 20 in the housing space S can be pushed out from the outlet 11 and applied to a predetermined position. The analgesic ointment 20 is for application to the skin of the human body and contains a heat-changing composition, a cooling agent, and a herbal complex extract. For example, the analgesic ointment 20 is formed by mixing the heat-changing composition, the cooling agent, and the herbal complex extract in predetermined proportions. By adding the heat-changing composition, the analgesic ointment 20 changes to different colors depending on the rise in skin temperature and the degree of skin tension. The cooling agent enhances the long-lasting cooling sensation after application and improves the sticky feeling often seen with commercially available ointments. Furthermore, the herbal complex extract alleviates pain and stiffness, and enhances the skin penetration of the analgesic ointment 20, allowing for efficient absorption of the herbal components at the application site and relieving muscle soreness. Therefore, after applying the analgesic ointment 20 to the skin, its color changes in accordance with the rise in skin temperature and the degree of skin tension, allowing for guidance on use and feedback on its effectiveness. For example, by combining the color change at the application site with methods such as massage or acupressure, pain and stiffness can be alleviated and absorption efficiency improved. It is also possible to judge the accuracy of the application site based on the color and make appropriate adjustments. For example, the analgesic ointment 20 is transparent before application (see Figure 6), but after application to the skin of the hand, it changes to a different color in accordance with the skin's temperature (see Figure 7), allowing the user to easily identify the application site. Furthermore, in some embodiments, the heat-change composition includes heat-change microcapsule components to allow the user to identify the color of the analgesic ointment 20. In response to increases in skin temperature and skin tension, the heat-change microcapsule components cause a noticeable color change in the analgesic ointment 20, allowing the user to easily identify the application site and area.In practice, the heat-changeable microcapsule components are micron-sized coated, and these micron-sized coated components can exist stably in hydrogel and latex substrates, making them widely applicable to various ointment products and further improving product functionality and user experience.

[0010] More specifically, to provide a cooling sensation after application of the analgesic ointment 20 and to prevent stickiness from affecting user comfort, the cooling agent contains at least menthol and menthyl lactate. Menthol provides an immediate cooling sensation to the skin, while menthyl lactate maintains a longer-lasting cooling sensation. By mixing these, the cooling sensation after application is effectively enhanced, offering advantages such as a multi-stage release system and long-lasting cooling. Furthermore, the herbal complex extract is encapsulated in either liposomes or nanocolloids. Liposomal or nanocolloidal encapsulation effectively protects the herbal components, improving the permeability, clarity, and stability of the drug's effects, while also promoting penetration and absorption into the skin, enhancing therapeutic effects, and extending the duration of action. To more effectively alleviate the user's pain and stiffness, in some embodiments, the herbal complex extract contains Yitiao root, frankincense, and ginger extract. Yitiao root has anti-inflammatory and analgesic properties and effectively relieves muscle and joint tension and discomfort. Frankincense has excellent muscle relaxant properties, promoting blood circulation and reducing muscle fatigue. Ginger extract, with its natural anti-inflammatory and antioxidant properties, alleviates muscle and joint discomfort caused by exercise and daily activities, and promotes recovery. Therefore, by combining these ingredients, pain-relieving ointment 20 effectively relieves pain and stiffness.

[0011] To further enhance absorption efficiency into the skin, in some examples (see Figure 4), the analgesic ointment 20 includes at least one penetration enhancer. For example, the penetration enhancer is selected from ethoxydiglycol, silicone oil, or glycerin. Ethoxydiglycol has excellent solubility and skin affinity and promotes penetration into the stratum corneum. Silicone oil has excellent film-forming properties and volatility, improving the spreadability and uniformity of absorption of the analgesic ointment 20 on the skin. Glycerin maintains the moisture retention state of the stratum corneum, softens the skin barrier, and helps penetrate to the deeper layers of the skin. Therefore, by adding one or more penetration enhancers, the analgesic ointment 20 can effectively penetrate to the deeper layers of the skin and improve the absorption efficiency of the herbal complex extract. In some examples, the analgesic ointment 20 further The ointment contains aerated silicone powder (see Figure 5). This aerated silicone powder is a spherical powder with a hollow structure and possesses excellent oil absorption and texture modification capabilities. By adding aerated silicone powder, the stickiness after application of the analgesic ointment 20 is effectively reduced, the dry and refreshing feeling on the skin is improved, and the adhesion of the ointment to the skin surface is improved, thereby enhancing the overall comfort of the user and the texture of the product. Therefore, by adding aerated silicone powder, the analgesic ointment has advantages such as a smooth feel on the skin, a refreshing feeling due to oil absorption, and prevention of adhesion to clothing.

[0012] The advantages and effects of the analgesic ointment of this invention are summarized as follows. [1] Intelligent color change presentation: By uniformly dispersing heat-changeable microcapsule components in the ointment, the color changes according to the surface temperature and inflammation state of the application site, providing a visual indication of use. [2] Triple cooling release: Combining immediate-release menthol and menthyl lactate to create a multi-stage, long-lasting cooling sensation that lasts for at least 12 hours. [3] Introduction of herbal extracts: By using a liposome encapsulation method, herbal complex components such as Yi Tiao Gen are stabilized, improving absorption rate and permeability of medicinal effects while maintaining a transparent and colorless texture. [4] High penetration and refreshing feel: By combining penetration enhancers (e.g., ethoxydiglycol, silicone oil, glycerin) and airy silica powder, a smooth, quick-drying, and non-sticky feel is achieved. In practical terms, the analgesic ointment of this invention is not limited to filling soft shell bodies, but can also be applied to analgesic relief ointments, cooling health creams, cooling patches for rehabilitation, cooling repair gels for pre- and post-exercise use, and cooling products for joints. Furthermore, by combining the analgesic ointment with sunscreens, skincare products, and medical dressings, it is possible to obtain effects such as sunscreen indication, skincare indication, and intelligent medical indication through color change. From the above description, this analgesic ointment effectively improves the penetration and absorption efficiency of the active ingredient into the skin through the interaction of the herbal complex extract and penetration enhancer, and further provides immediate relief and visual identification functions when combined with a cooling agent and a heat-color-changing composition. As a result, it can provide multi-sensory effects and usage guidance functions, improving the effect of alleviating skin discomfort and ease of use. Therefore, the analgesic ointment of this invention combines aesthetic appearance, comfort of use, and strength of therapeutic effect, and has a visual color-changing indication function, representing a significant innovative improvement over conventional analgesic ointments.
