Preserved tea container

The invention relates to a container structure for preserving tea leaves, in particular to a container for preserving tea leaves which has excellent ventilation effect and moisture proof function.

According to the tea, the more special thing is that the longer the "aging" is, the stronger the tea is. The so-called "aging" refers to the oxidation of tea. Tea leaves with rich flavor and rich flavor, the perfect performance of Chen Yun, tea and tea, all depend on the correct storage method. The process of tea aging is affected by many factors such as light, air convection and humidity. If any link is wrong, the tea quality and tea will be greatly reduced.
Taiwan's main island is located in the subtropical zone. The climate is suitable for storing tea leaves. The appropriate humidity can promote the aging of tea. However, in the rainy season, the relative humidity in the air is high. At this time, it is necessary to pay attention to the treatment of humidity. Some teas themselves have a strong absorption capacity for moisture, mainly because the tea leaves are loose multi-capillary structures, and the tea leaves have many hydrophilic substances such as tea polyphenols, esters and sugars, etc. The humidity can promote the aging of the tea. However, the relative humidity of the surface air tends to be higher, and in the case of higher relative humidity, the tea will be mildewed and spoiled.
The tea leaves are stored in the opaque container body to avoid direct sunlight. Because the plant pigments and lipids in the tea are more susceptible to photochemical reactions, the long-term exposure to direct sunlight will cause the tea to produce odor, and after sun exposure. The ambient temperature will rise. When the ambient temperature is high, the chlorophyll degradation in the tea will be accelerated. The chlorophyll will be continuously converted into pheophytin, and the oxidation rate of tea polyphenols will be accelerated in the high temperature environment. In addition to affecting the quality of tea, in addition to maintaining the circulation of air, it is beneficial to the growth of microorganisms in tea, which can accelerate the aging of tea. However, if the tea leaves are placed in an open space, the tea and tea taste of the tea will be blown away. The tea leaves are light and tasteless, and it is known that the container for storing tea leaves is quite important.
However, the conventional container for storing tea leaves can be roughly divided into two types in the process, one of which is made of ceramics under high temperature sintering to make a ceramic container with excellent gas permeability, and the other is used when the clay is sintered at a high temperature. An enamel container made of glaze attached to the surface of the clay. However, although the former has a good air circulation effect, when the relative humidity of the surface is high, moisture from the surface easily enters the container to cause mildew of the tea. The latter, although the glaze blocks the moisture from entering the container, it cannot circulate the air inside the container to the outside world, which is not conducive to the proliferation of microorganisms in the tea, so that the tea takes a long time to complete the aging, however, Because the ground has a material with a high water absorption rate, the relative humidity of the air close to the surface tends to be relatively high. Therefore, only the top coat is applied to the circumferential surface of the container and the top cover, and the relative humidity near the surface cannot be prevented. Air enters the interior of the container from its bottom surface, and there is also the problem that tea leaves are prone to mildew.
In view of this, how to solve the above problem is the primary problem to be solved by the present invention. Therefore, the inventor of the present invention finally has the invention after continuous arduous thinking and trial work.

The main object of the present invention is to provide a container for preserving tea leaves, wherein the bottom of the container body and the circumferential mask have a connecting barrier layer, and the barrier layer can block air with relatively high humidity near the surface from entering the container, which can effectively prevent The tea leaves are mildewed, and the area covered by the insulation layer can keep the air circulation in the container to accelerate the aging of the tea.

Referring to Figures 1 and 2, the structure of the first embodiment selected for use in the present invention is for illustrative purposes only and is not limited by such structure in the patent application.
A first embodiment of the present invention provides a container for preserving tea leaves, which is mainly composed of a hollow and opaque container body 11 having a circumferential wall 12 having a circumferential wall 12 in the container body. An inner peripheral surface 121 of the portion, and an outer peripheral surface 122 facing the outer space, and the container body 11 has an opening 13 at one end thereof, the opening 13 communicating with the inside of the container body 11, and the other of the container body 11 One end has a bottom portion 14 having an inner bottom surface 141 inside the container body and an outer bottom surface 142 on the outer side for contacting the ground. Further, the container body 11 has a maximum height H, which is the maximum. The height H is the height from the bottom 14 to the opening 13. In the present embodiment, the container body 11 is made by a high temperature sintering and subsequent process of an embryo body, and the embryo system is made of clay containing a large amount of iron, and then the un-emerged embryo body is It is naturally dried at room temperature. After the embryo body is dry and its color changes from earthy yellow to light gray, the embryo body can be subjected to high temperature burning. The embryo body after high temperature burning is not only harder in structure, but also prevents subsequent When the step of glazing is performed, the body body absorbs excessively due to excessive water absorption, and the body body is heated by the high temperature body to become the container body 11, and a plurality of natural bodies are formed on the container body 11. The fine pores 15 and the high-density and fine pores 15 allow air convection in the inner space and the outer space of the container body 11, thereby allowing the container body 11 to have a function of adjusting humidity and temperature.
Next, an insulating layer 21 is attached to a predetermined portion of the outer surface of the container body 11. In the embodiment, the insulating layer 21 is composed of a glaze, wherein the glaze can be made of a high temperature glaze and a medium temperature. The glaze or the low-temperature glaze is formed by glazing, which is one of the steps in the process of the ceramics, that is, coating or otherwise attaching a high-temperature molten liquid glaze to the outer surface of the container body 11, in this embodiment The glaze is extended from the outer bottom surface 142 of the bottom portion 14 to the outer peripheral surface 122 of the circumferential wall 12, and the height of the glaze extending from the outer bottom surface 142 to the partial outer peripheral surface 122 is at least the container. One third of the maximum height H of the body 11 (as shown in FIG. 2), after the container body 11 is glazed, the container body 11 to which the glaze has been attached is glazed at a certain high temperature, and the glaze is burned at a certain high temperature. The glaze is converted into a molten liquid at a high temperature and is bonded to the opposite outer surface of the container body 11, so that the glaze is firmly bonded to the container body 11 and formed by the outer bottom surface 14 The insulating layer 21 covering the outer peripheral surface 122 of the peripheral wall 12 is extended upward, and the height h of the insulating layer 21 extending from the outer bottom surface 142 to the outer peripheral surface 122 is at least three thirds of the maximum height H of the container body 11. First, the air hole 15 on the opposite outer surface (ie, the outer bottom surface 142 and the partial outer circumferential surface 122) of the container body 11 is closed, and the surface of the remaining circumferential wall 12 not covered by the insulation layer 21 is formed to have gas permeability. Clay layer 16. Therefore, the air having an outer space close to the surface and having a relatively high relative humidity cannot enter the inner space of the container body 11 through the air holes 15 on the outer bottom surface 142 and the outer peripheral surface 122 of the container body 11, so that the air can be made The inner space of the container body 11 is kept dry and moisture-proof. In addition, the insulation layer 21 not only blocks moisture from entering the inner space, but also effectively improves the hardness of the container body 11 and the ability to resist acid-base corrosion.
When the present invention consists of the above-mentioned structure, in actual use, as shown in FIG. 3, the container body 11 is placed on the ground with its outer bottom surface 142, and the inner space of the container body 11 is stored with a tea leaf 31, which is 31. It is stored in the opaque container body 11 to avoid direct sunlight. Therefore, the tea leaf 31 can be maintained in an optimum state by the shielding of the container body 11.
The tea leaves 31 are stored in the interior of the container body 11, and the air in the inner space of the container body 11 can be convected with the external space by the high-density and fine air holes 15 on the clay layer 16 of the container body 11 (as shown in FIG. 3). As shown by the solid arrow, in the growing environment of air circulation, the growth of microorganisms in the tea leaves 31 can be accelerated, and the speed of the aging of the tea leaves 31 can be accelerated.
Furthermore, the insulation layer 21 extends upward from the outer bottom surface 142 of the container body 11 to the outer circumferential surface 122 of the circumferential wall 12, and the insulation layer 21 extends from the outer bottom surface 142 to the height h of the outer circumferential surface 122. At least one third of the maximum height H of the container body 11, so that the air holes 15 on the opposite outer surface of the container body 11 can be closed, so that the moisture of the surface can be effectively prevented by the insulation layer 21 (such as The inside of the internal space is shown in the dotted line in Fig. 3, so that the internal space can be kept dry, and the tea leaves 31 stored in the container body 11 are not affected by the air having a relatively high relative humidity on the surface and are mildewed.
In summary, it can be seen that the tea leaves 31 stored in the container for preserving tea leaves provided by the present invention can be protected from direct sunlight, and the inner space and the outer portion can be made by the air holes 15 in the gas-permeable ceramic layer 16 of the container body 11. The air of the space has good convection, and the container body 11 placed on the ground is covered by the bottom surface 142 of the container body 11 to cover the outer peripheral surface 122 of the circumferential wall 12 by the insulating layer 21, so The air which is close to the surface and has a relatively high relative humidity is effectively blocked from entering the inside of the container body 11, so that the tea leaves 31 can be aged in an optimal environment and retain its tea quality and tea atmosphere.
Next, referring to FIG. 4, which is a second embodiment of the present invention, the second embodiment is different from the first embodiment in that the container body 11 has a maximum outer diameter D, and the insulation layer 21 is composed of the container body. 11 The outer bottom surface 142 extends to a height h of the outer peripheral surface 122 which is less than one-half of the maximum outer diameter D (as shown in FIG. 4), and the insulating layer 21 is also effective for preventing air having a relatively high relative humidity near the surface. It is impossible to enter the inside of the container body 11, and the same can be achieved for good gas permeability and moisture resistance.
Please refer to FIG. 5, which is a third embodiment of the present invention. The third embodiment is different from the above embodiment in that the insulating layer 21 covering the container body 11 is inside the container body 11. The bottom surface 141 extends upwardly to cover the inner circumferential surface 121 of the circumferential wall 12 portion, and the insulation layer 21 extends from the inner bottom surface 141 to the height h of the inner circumferential surface 121 at least three thirds of the maximum height H of the container body 11. First, the insulating layer 21 inside the container body 11 can also effectively prevent air having a relatively high relative humidity near the surface from entering the inside of the container body 11 from the external space, and can also have good gas permeability and moisture-proof effect.
Referring to FIG. 6, which is a fourth embodiment of the present invention, the fourth embodiment differs from the third embodiment in that the inner bottom surface 141 of the container body 11 storing the tea leaves 31 and the peripheral wall portion 12 are The inner peripheral surface 121 is covered with the insulating layer 21 for insulating water, and the insulating layer 21 extends from the inner bottom surface 141 of the container body 11 to a height h of the inner peripheral surface 121 which is smaller than a half of the maximum outer diameter D. First, the insulation layer 21 can also prevent air having a relatively high relative humidity near the surface from entering the inside of the container body 11, and thereby keeping the inside of the container body 11 dry and well ventilated.
Since the insulating layer 21 of the present invention is designed to extend from the bottom portion 14 of the container body 11 to the height h of the circumferential wall 12 at least one third of the maximum height H of the container body 11 or from the bottom portion 14 of the container body 11 to The height h of the circumferential wall 12 is less than one-half of the maximum outer diameter D, mainly because the container is tall and thin, and the excessive or too small barrier layer 21 affects the gas permeable area of the clay layer 16 and the moisture barrier of the insulation layer 21. The area is designed such that the insulating layer 21 is sufficiently effective to prevent air having a relatively high relative humidity near the surface from entering the inside of the container body 11 and allowing the ceramic layer 16 having a gas permeability to have a large gas permeable area, and can surely achieve the same. It has good breathability and moisture resistance.
The disclosure of the above embodiments is intended to be illustrative of the invention and is not intended to limit the invention.
In summary, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives and is in compliance with the provisions of the Patent Law.
