A child-resistant package includes a nonrupturable layer, a rupturable layer attached to the nonrupturable layer, and a blister sheet attached to the rupturable layer. The blister sheet includes at least one article-receiving pocket which is covered by a portion of the rupturable layer. A portion of the nonrupturable layer is not attached to the rupturable layer to form a pull tab which extends in a first direction which does not extend toward the pocket. An article in the pocket can be accessed only by pulling the tab in the first direction and then pulling the tab in a second direction which extends toward the pocket to expose the portion of the rupturable layer which covers the pocket. The article can then be pushed through the rupturable layer.

Child-resistant package

A child-resistant package is resistant to being opened by a child because the package challenges the cognitive skills of a child. However, the package can be easily opened by the elderly or the physically impaired. The package includes either one or a plurality of fold lines, and a tear notch extends across only one of the fold lines. The package can be opened by folding along the fold line with the tear notch and then tearing the package along the tear notch. The package may also include a tear strip which extends between the tear notch and the contents of the package. If a child tears the package along the tear strip, the tear notch is removed and the package is disarmed and prevented from being opened.

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.

A radon measuring device having a housing formed by at least two mating portions. The housing includes a plurality of apertures along at least one of its surfaces to permit entry of ambient atmosphere into said housing, a membrane or filter positioned proximate an interior surface of the housing covering the apertures for filtering the ambient atmosphere which enters the housing, and a radon detector within the housing positioned in a plane substantially normal to the surface of the housing containing the apertures. The housing can also include a filter holder within its interior for positioning both the filter and the detector in their respective positions as well as alignment tracks for alignment of the filter holder with respect to the housing.
