Description

Technical Field

[0001] This utility model relates to the field of essential oil storage technology, and in particular to a storage device for ensuring the quality of essential oils. Background Technology

[0002] Essential oils are widely used in aromatherapy, massage, and skincare products due to their unique aroma and multiple benefits. However, essential oils are highly volatile, easily oxidized, and susceptible to quality degradation caused by light and temperature. Existing essential oil storage containers are mostly simple glass or plastic bottles with screw caps for sealing, which are ineffective in preventing oxygen ingress and essential oil evaporation. Furthermore, the lack of light-protection measures or inadequate light protection allows essential oils to undergo chemical reactions under light exposure during prolonged storage, affecting their quality and efficacy, and potentially even causing spoilage and the production of harmful substances. This fails to meet the demand for high-quality essential oil storage.

[0003] Therefore, there is an urgent need for a storage device that can ensure the quality of essential oils. Utility Model Content

[0004] The purpose of this invention is to provide a storage device that ensures the quality of essential oils. By optimizing the sealing structure, increasing the antioxidant function, and designing a light-blocking system, the quality of essential oils can be kept stable during storage, effectively solving the problems of poor sealing and easy oxidation caused by poor light-blocking effect in existing essential oil storage equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A storage device for ensuring the quality of essential oils includes a container and a lid. The container has an inner liner for storing essential oils inside, and the top of the inner liner has an opening. A sealed cavity is formed between the inner liner and the container, and the sealed cavity is filled with an inert gas. The lid has a silicone sealing plug for tightly fitting the opening of the inner liner. The outer wall of the container has a light-shielding layer made of multiple layers of composite material, which includes an outer aluminum foil layer, a middle fiber reinforcement layer, and an inner EVA layer.

[0007] Furthermore, the inner liner has a double-layer structure, comprising an inner layer of high borosilicate glass and an outer layer of heat-insulating coating. By adopting a double-layer structure and incorporating the heat-insulating coating, the heat retention performance of the inner liner is enhanced, reducing the impact of external temperatures on the essential oils.

[0008] Furthermore, the opening of the inner liner is provided with a ring-shaped arrangement of positioning rings for abutting against the silicone sealing plug, and the upper part of the borosilicate glass layer is fixedly connected to the positioning rings. In this way, the silicone sealing plug can elastically abut against the positioning rings and form a good seal with them.

[0009] Furthermore, the thickness of the light-shielding layer is 2mm~3mm, the thickness of the aluminum foil layer is 0.1mm~0.2mm, the thickness of the fiber reinforcement layer is 1.5mm~2mm, and the thickness of the EVA layer is 0.4mm~0.8mm. This combination of thicknesses ensures good light-shielding effect without making the material too bulky.

[0010] Furthermore, the sealed cavity is provided with a buffer block connecting the bottom of the inner liner and the bottom of the tank body.

[0011] Furthermore, the can lid includes an outer lid and an inner lid connected together, the inner wall of the outer lid is threadedly connected to the upper outer wall of the can body, and the silicone sealing plug is fixed to the bottom of the inner lid.

[0012] Furthermore, the silicone sealing plug, the inner cover, and the outer cover are locked together by threaded fasteners.

[0013] Furthermore, the bottom of the silicone sealing plug is provided with an upwardly recessed groove, and a sealing block for covering threaded fasteners is embedded in the groove.

[0014] Furthermore, the outer periphery of the inner cover is provided with downwardly protruding annularly distributed retaining edges.

[0015] Furthermore, the top of the outer cover is provided with a handle for easy opening.

[0016] Compared with the prior art, this utility model provides a storage device for ensuring the quality of essential oils, which has the following beneficial effects:

[0017] (1) By setting up a sealed cavity between the inner liner and the tank and filling it with inert gas, the heat preservation of the storage device is enhanced, which can maintain the essential oil at a suitable storage temperature, prevent the essential oil from deteriorating due to temperature changes, and ensure that the quality of the essential oil is not affected by the external ambient temperature.

[0018] (2) The silicone sealing plug at the bottom of the lid is used to elastically seal the opening of the inner liner, which greatly enhances the sealing of the storage device, effectively isolates oxygen, reduces the oxidation and volatilization of essential oils, and extends the shelf life of essential oils.

[0019] (3) The multi-layered composite light-blocking layer on the outer wall of the container can effectively block light from entering, prevent the essential oil from undergoing a chemical reaction due to light exposure, thus ensuring the stability and efficacy of the essential oil.

[0030] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] Please refer to Figures 1-8This embodiment provides a storage device for ensuring the quality of essential oils, including a container 1 and a lid 4. The container 1 has an inner liner 2 for storing essential oils. The top of the inner liner 2 has an opening 21, and a sealed cavity 3 is formed between the inner liner 2 and the container 1. The sealed cavity 3 is filled with an inert gas (e.g., nitrogen), the pressure of which is slightly higher than the external atmospheric pressure. This enhances the sealing performance of the cavity and effectively isolates oxygen, while also improving the heat retention of the storage device. This maintains the essential oils at a suitable storage temperature, preventing them from deteriorating due to temperature changes and ensuring that the quality of the essential oils is not affected by external ambient temperature. The lid 4 has a silicone sealing plug 5 for tightly fitting with the opening 21 of the inner liner 2. When the lid is installed, the silicone sealing plug elastically inserts and tightly engages with the opening of the inner liner, forming a good seal. This greatly enhances the sealing performance of the storage device, effectively isolates oxygen, reduces the oxidation and volatilization of the essential oils, and extends their shelf life. The outer wall of the container 1 is provided with a light-shielding layer 11 composed of multiple layers of composite materials. The light-shielding layer 11 includes an outer aluminum foil layer 111, a middle fiber reinforcement layer 112, and an inner EVA layer 113 (i.e., an ethylene-vinyl acetate copolymer layer). The aluminum foil layer effectively reflects light, the fiber reinforcement layer improves the overall strength and stability of the light-shielding layer, and the EVA layer ensures a tight bond between the light-shielding layer and the container, enhancing adhesion. The overall light-shielding effect is excellent, blocking more than 99% of light from entering the container, ensuring that the essential oils are protected from light exposure. Through the multi-layered composite light-shielding layer on the outer wall of the container, light is effectively blocked from entering, preventing chemical reactions in the essential oils caused by light that could lead to a decline in quality, thus ensuring the stability and efficacy of the essential oils.

[0032] In some specific embodiments, for example, the can 1 is made of highly transparent glass with a wall thickness of 3mm. In other embodiments, the can 1 can also be made of frosted plastic, giving it a certain degree of self-shading effect. Alternatively, the can 1 can be made of dark brown glass, giving it a certain degree of light-blocking properties. Furthermore, the thickness of the can 1 can be set to other thickness values ​​according to actual production needs, such as 2.5mm, 3.5mm, etc., and is not limited to 3mm.

[0033] In some specific implementation methods, refer to Figure 2 and Figure 4 The inner liner 2 has a double-layer structure, comprising an inner borosilicate glass layer 22 and an outer heat-insulating coating 23. By adopting a double-layer structure and incorporating the heat-insulating coating, the heat insulation performance of the inner liner is enhanced, reducing the impact of external temperature on the essential oils. As an example, the thickness of the borosilicate glass layer 22 is 3.5 mm, and the thickness of the heat-insulating coating 23 is 2 mm.

[0034] In some specific implementation methods, refer to Figure 2 , Figure 5 and Figure 6 The inner liner 2 has an opening 21 with a ring-shaped arrangement of positioning rings 24 for abutting against the silicone sealing plug 5. The upper part of the borosilicate glass layer 22 is fixedly connected to the positioning rings 24 by an adhesive material. In this way, the silicone sealing plug can elastically abut against the positioning rings and form a good seal with the positioning rings.

[0035] In some specific embodiments, the thickness of the light-shielding layer 11 is 2mm to 3mm, the thickness of the aluminum foil layer 111 is 0.1mm to 0.2mm, the thickness of the fiber reinforcement layer 112 is 1.5mm to 2mm, and the thickness of the EVA layer 113 is 0.4mm to 0.8mm. This combination of thicknesses ensures good light-shielding effect without making the material too bulky.

[0036] As an example, in some embodiments, the thickness of the light-shielding layer can be designed to be 2.6 mm, the thickness of the aluminum foil layer to be 0.15 mm, the thickness of the fiber reinforcement layer to be 1.8 mm, and the thickness of the EVA layer to be 0.65 mm. Alternatively, in another embodiment, the thickness of the light-shielding layer can be designed to be 3 mm, the thickness of the aluminum foil layer to be 0.2 mm, the thickness of the fiber reinforcement layer to be 2 mm, and the thickness of the EVA layer to be 0.8 mm. Yet another embodiment may have the following thicknesses: the thickness of the light-shielding layer to be 2.5 mm, the thickness of the aluminum foil layer to be 0.1 mm, the thickness of the fiber reinforcement layer to be 1.9 mm, and the thickness of the EVA layer to be 0.5 mm.

[0037] In some implementations, reference Figure 2 The sealed cavity 3 is equipped with a buffer block 6 connecting the bottom of the inner liner 2 and the bottom of the tank body 1. This buffer block allows the inner liner to be stably supported inside the tank body and also provides shock absorption due to its material properties. As an example, the buffer block is a rubber block, and four of them are provided.

[0038] In some specific implementation methods, refer to Figure 1 , Figure 2 , Figures 5-8 The can lid 4 includes an outer lid 41 and an inner lid 42 connected together. The inner wall of the outer lid 41 is threadedly connected to the upper outer wall of the can body 1. A silicone sealing plug 5 is fixed to the bottom of the inner lid 42. The silicone sealing plug 5, the inner lid 42, and the outer lid 41 are locked together by threaded fasteners 7. Specifically, the threaded fasteners 7 are screws. As an example, the outer lid 41 is made of plastic, and the inner lid 42 is made of stainless steel.

[0039] As an improved implementation method, refer to Figure 2 , Figure 7 and Figure 8The bottom of the silicone sealing plug 5 has an upwardly recessed groove 53, into which a sealing block 8 covering the threaded fastener 7 is embedded. By adding the sealing block, the exposed threaded fastener can be prevented from being exposed and direct contact with the essential oil can be avoided. As an example, the sealing block is a rubber block.

[0040] In some specific implementation methods, refer to Figure 2 , Figure 5 , Figure 7 and Figure 8 The silicone sealing plug 5 includes a cylindrical sealing portion 51 and a disc-shaped positioning portion 52. The outer peripheral sidewall of the sealing portion 51 is provided with a plurality of annularly distributed ribs 54. As an example, the diameter of the sealing portion 51 is slightly smaller than the diameter of the opening 21 of the inner liner 2, and its height is 10 mm.

[0041] In some specific implementation methods, refer to Figure 2 , Figure 5 , Figure 7 and Figure 8 The inner cover 42 has downwardly protruding annularly distributed retaining edges 421 along its outer periphery. In this way, the retaining edges can be used to position the silicone sealing plug, thereby quickly and accurately assembling the silicone sealing plug with the inner cover and the outer cover.

[0042] In some implementations, reference Figure 1 , Figure 2 and Figure 6 The top of the outer cover 41 is further provided with a handle 411 for easy opening.

[0043] refer to Figure 1 , Figure 2 and Figure 6 When using, first grasp the handle 411 to rotate the lid 4 and remove it, then pour the essential oil into the inner liner 2. Then, put the lid 4 back on and tighten it again, so that the silicone sealing plug 5 tightly seals the opening 21 of the inner liner 2. The light-blocking layer 11 blocks external light from entering the can body 1, and through the multi-layer sealing structure formed by the can body 1 and the inner liner 2, the essential oil can be maintained within a relatively constant temperature range.
