Description

Desiccant and dry pack using the desiccant

The present invention mainly discloses a desiccant, especially a desiccant comprising calcium chloride and mineral soil.

When storing items, the damp environment is almost the enemy of all items. Whether it is food, medicine, clothing, paper or electronic equipment, it can not be stored for a long time in a humid environment. It is very easy to breed mold in a humid environment. When the food and medicine are mildewed, they can no longer continue to eat; when the clothes and paper are moldy, they will smell and yellow, and it is difficult to clean; while the metal parts in the electronic equipment may cause embrittlement in a humid environment, if it is photographic equipment, The coating on the lens may also be moldy, eventually leading to damage to the electronic equipment.

In order to create a good environment for preserving articles, a desiccant has been developed. Generally, the desiccant is composed of calcium chloride and is packaged through a ventilated paper, a non-woven fabric, a composite paper or a textured paper to form a dry package. Calcium chloride material has good water absorption, and the ventilated paper, non-woven fabric, composite paper or textured paper can be ventilated. The dry package can be placed in the closet, closet or storage box to absorb moisture by calcium chloride. Reduces the effect of humidity in the air, thereby extending the shelf life of the item.

However, calcium chloride is solid in a dry state and can form granules or powders, but calcium chloride is converted into a liquid state after being absorbed by water. If the dry bag adsorbs water and sucks to saturation, the dry bag not only has no adsorbed water at this time. The effect of gas, even the aqueous solution of calcium chloride in the dry bag may ooze out. If the user does not immediately replace the new dry bag, the calcium chloride solution may be contaminated on the items stored by the user, but the storage is increased. trouble.

In view of the above-described deficiencies in the conventional structures, the inventors have invented a desiccant which overcomes all of the disadvantages of the above-described conventional structures.

The main purpose of the desiccant of the present invention is to provide a desiccant comprising calcium chloride and mineral soil, wherein the calcium chloride accounts for 10% to 90% by weight, and the mineral soil accounts for 10% to 90% by weight. %, because the desiccant has calcium chloride, the desiccant has good water absorption, and because the desiccant has mineral soil, the desiccant can form a solid after absorbing water, and the moisture absorbed by the desiccant can be prevented from seeping again through the gas permeable layer. Keep the dry bag clean.

The technology, means and functions of the present invention are described in detail with reference to the accompanying drawings.

1 to 3 are a perspective external view of the drying bag of the present invention, a perspective view of the other viewing angle, and a cross-sectional structural view. The drying bag 10 of the present invention comprises an outer package 20 and a desiccant 30; wherein:

The outer package 20 includes a gas permeable layer 21 and an indicator layer 22, and the gas permeable layer 21 and the indicator layer 22 overlap each other. The outer package 20 forms an accommodating space 23 between the gas permeable layer 21 and the indicator layer 22. . The indicator layer 22 has a white color, and the indicator layer 22 includes at least one transparent portion 24 that can pass light. The transparent portion 24 forms a special pattern, and the transparent portion 24 is in the embodiment. The pattern is an umbrella, and the at least one transparent portion 24 is plural in number in this embodiment.

The indicator layer 22 further includes at least one first pattern portion 25, the pattern of the first pattern portion 25 in the embodiment is a lizard, and the first pattern portion 25 and the transparent portion 24 are connected to each other to form at least one a second pattern portion 26, the indicator layer 22 further having at least one third pattern portion 27, the pattern of the third pattern portion 27 being the same as the pattern of the second pattern portion 26, the number of the at least one first pattern portion 25, The number of the at least one second pattern portion 26 and the number of the at least one third pattern portion 27 are both several and the same in this embodiment.

The desiccant 30 is disposed in the accommodating space 23, and the desiccant 30 comprises calcium chloride and mineral soil, and the calcium chloride accounts for 10% to 90% by weight, and the weight of the calcium chloride The percentage is preferably 50% to 90% in the present embodiment, and the mineral clay accounts for 10% to 90% by weight, and the mineral soil accounts for 10% to 50% by weight in this embodiment. good. The mineral soil can be diatomaceous earth, ore clay, clay, bentonite, volcanic rock, diatomaceous earth, white clay and combinations thereof, and the mineral soil is preferably diatomaceous earth or diatomaceous earth.

The drying bag 10 can be placed in a damp place of a general household in use, such as a wardrobe or a storage box, and moisture in the air can enter the accommodating space 23 through the gas permeable layer 21 of the outer package 20, and the drying The agent 30 is capable of adsorbing moisture entering the accommodating space 23 to achieve the effect of dry dehumidification. Since the desiccant 30 has calcium chloride in the desiccant 30, the desiccant 30 has good water absorbability, and the water absorption rate of the desiccant 30 is 130% in the present embodiment, and since the desiccant 30 has mineral soil, After the desiccant 30 absorbs water, it can form a solid state, and the moisture absorbed by the desiccant 30 is prevented from oozing out again through the gas permeable layer 21, keeping the dry pack 10 clean.

Please refer to FIG. 4 and FIG. 5 for further description of the state of use of the drying bag of the present invention and the state of use when the water vapor is saturated. And because the mineral soil will change color after being exposed to moisture, generally it is changed from light color to dark color, especially the mineral soil can be diatomaceous earth or diatomaceous earth, the color of diatomaceous earth or diatom earth in dry state In the white color, when the diatomaceous earth or the diatomaceous earth absorbs water, it turns from the original white color to the green color, and the transparent portion 24 of the indicating layer 22 can transmit light, so that the user can directly observe the desiccant 30. The color is convenient for the user to accurately judge the timing of replacing the new drying bag 10, and the humidity of the wardrobe or the storage box is prevented from rising due to the failure of the drying bag 10 due to saturation of the adsorbed water.

When the dry package 10 is in a dry state, the indication layer 22 displays only the first pattern portion 25 and the third pattern portion 27. Since the indicator layer 22 has the third pattern portion 27, it has the effect of increasing the aesthetic appearance of the dry bag 10, and can provide a comparison basis for the user to judge the timing of replacing the dry bag 10. When the moisture in the drying bag 10 is saturated and the pattern of the transparent portion 24 is floated, the patterns on the indicating layer 22 are all the same, even if the drying bag 10 is used for the first time and the text is read in detail.
