| 摘要 |
A diet pill in the form of a sealed container of cellulose material containing a gas producing powder, such as sodium bicarbonate which expands the pill in volume as the result of reaction with gastric juice and liquid in the user's stomach. Such expansion gives a sense of fullness of the stomach. The pill may also contain a fiber, such as psyllium hydrophillic mucilloid, which swells in the user's stomach. The pill may be tubular and sealed by end ties of silk or catgut or other digestible or indigestible material. The tubular pill may be compacted in size by folding several times or collapsing in accordion fashion to enable swallowing.
