The process and apparatus of this invention can be used to separate and recover particles from a liquid sample. The preferred embodiment of this invention is to separate and recover microorganisms, particularly Cryptosporidium oocysts, from a variety of environmental sources. The process consists of applying a municipal drinking water coagulation scheme to an environmental water sample, and the aforementioned water sample is then filtered through an apparatus containing a granular filter material. The analyte is then recovered by agitating the filter vigorously (with a dispersing agent inside) and removing the eluent from the filtration apparatus. The eluent can then by aliquotted and assayed by any means available. The floc resulting from the coagulant addition can typically be dissolved at low pH. The filter apparatus is simply a container that allows the passage of water through a granular material while retaining the granular material via a mesh, screen, or similar material.

A multi layered leak proof tamper evident container closure seal with an integral pull opener is constructed from a first layer of leak proof frangible sheet material that is adhesively bonded to a second layer of strengthening sheet material. The strengthening layer contains a varied C shaped cut out void configuration that forms a breaking pattern that turns the strengthening layer into a break and tear template layer. The adhesive layer bonding the frangible layer to the template includes an area void of the adhesive that duplicates the cut out void configuration of the breaking pattern. The seal is also bonded to the container rim without any adhesive being present in the area of the cut out void configuration of the breaking pattern thereby leaving only the single frangible layer covering over the C shaped cut out void configuration forming the breaking pattern which creates a weakness in the multi layered seal only in the area of the C shaped breaking pattern. When a consumer forces a finger into the installed seal the applied pressure forces the seal to break open and tear only in the weaker area of the C shaped breaking pattern configuration that follows in close proximity the inside perimeter of the container rim while the rim contact portion of the seal remains bonded to the container rim. The broken open C shaped central portion of the seal then forms a connected pull tab that can be lifted back out and pulled from the container. The ability of the seal to be easily broken open while the rim contact portion of the seal remains bonded to the container rim allows the seal to be bonded to the rim with either a strong adhesive that forces the pull tab to tear from the rim contact portion of the seal, or a weak adhesive that allows the rim contact portion of the seal to peel from the container rim along with the pull tab.

Date Aug. 6, 1998There is described a bottle which once opened, cannot be resealed. The bottle is particularly suitable for medical applications, especially for holding eye wash solutions for emergency use. The bottle operates by having a head portion located within the cap, so that when the cap is twisted the head portion is at least partially removed from the remainder of the bottle. The head portion cannot then be reattached to the remainder of the bottle. Also described is a container for holding a non-resealable bottle, the container having a ledge, which co-operates with a part of the bottle which is only present in the unopened form. For example the cap or head portion of the bottle may comprise a lip or projection. The container plus at least one unopened bottle of the invention is useful as an emergency eye wash station.
