  • Patent number: 5310060
    Abstract: The present invention concerns a novel tamper-evident, child-resistant blister package for medicaments and nonmedicaments which is user-friendly, but which is difficult to open by young children and impaired adults.Because the blister package has pull tabs which are designed to be pulled away from, rather than towards, article-receiving pockets which may be present in the blister package other than the article-receiving pocket being accessed, a young child or user of the blister package can only access one article-receiving pocket at a time, whether deliberately or inadvertently.The blister package of the invention is an attractive and inexpensive package for the merchandising of pharmaceutical and other products which is constructed in a manner which facilitates mass production.
