  The present invention provides a device for modifying an atmosphere in proximity to the device, the device comprising a sachet comprising a semipermeable material, and a composition including a mixture of acetylsalicylic acid and sodium bicarbonate contained within a cavity of the sachet. The invention further provides methods for modifying an atmosphere comprising placing a mixture of a carboxylic acid and a base in the atmosphere, wherein the atmosphere has a sufficient level of water vapor such that, upon contact of the water vapor with the mixture, carbon dioxide is produced.

  本发明提供了一种用于改变靠近该装置的大气环境的装置，该装置包括一个由半透材料组成的小袋，以及一个包含在小袋空腔内的乙酰水杨酸和碳酸氢钠混合物的组合物。本发明进一步提供了改变大气环境的方法，包括将羧酸和碱的混合物置于大气中，其中大气中的水蒸气含量足够高，当水蒸气与混合物接触时，会产生二氧化碳。

  A method and means for enhancing the inner environment of a package containing perishable merchandise include taking a closable package containing perishable merchandise and placing in the package a multi-layered sheet including a plurality of layers comprised of moisture absorbing materials to absorb any residual moisture emanating from the perishable merchandise. The multi-layered sheet includes a quantity of CO 2 generating material incorporated therein. The CO 2 generating material is exposable to humidity and any residual moisture within the package and any moisture absorbing material to allow the CO 2 generating material to emit an atmosphere of CO 2 within the package from exposure to moisture within the air in the package, and to absorb any residual moisture in the package.

  一种用于改善装有易腐商品的包装内部环境的方法和装置，包括取一个装有易腐商品的可封闭包装，并在包装内放置一个多层薄片，该多层薄片包括由吸湿材料组成的多层，以吸收易腐商品散发出的任何残余湿气。多层板包括一定量的 CO 2 生成材料。二氧化碳 2 生成材料可暴露于湿度、包装内的任何残留湿气以及任何吸湿材料中，使 CO 2 生成材料释放出二氧化碳气体。 2 并吸收包装内的任何残留湿气。

  A compound permitting the economic production of packaging containers, which when activated produces concentrated amounts of CO2 gas for extended periods for preservation of perishable products therein, comprises a mixture including a CO2 generating portion incorporated within a polymer matrix. Preferably, the mixture includes citric acid; calcium carbonate, and polyethylene resin. More preferably, the mixture includes a mixture of a carboxylic acid (0.1-40%); a hydrogen carbonate (0.1-40%) and any polyolefin resin. Even more preferably, the mixture includes a mixture including (0.01-40%) Citric Acid; (0.01-40%); and 30-75% polyethylene resin. Most preferably, the mixture includes by weight 12% citric acid; 38% calcium carbonate; and 50% low density polyethylene resin with a melt index of 20 and a density of 0.924 g/cc. Alternatively, the carboxylic acid and hydrogen carbonate components are compounded into separate polymer matrixes, and later combined. The compound may be packaged in containers that are formed of flexible or rigid material.
