A sterile filling machine and related method are provided for sterile filling a container with a substance. The container includes a heat resealable stopper and a chamber for receiving the substance therein. The sealed, empty containers are subjected to radiation capable of penetrating through the stopper and chamber for sterilizing the container. The previously sterilized containers are then transported through an e-beam chamber, wherein an electron beam is directed onto a penetrable surface of the stopper to sterilize the penetrable surface. A needle is mounted within the e-beam chamber and moved into engagement with the stopper to pierce the sterilized penetrable surface of the stopper and inject the substance through the needle and into the chamber of the container. The needle is then withdrawn from the stopper and the filled container is transported outside of the e-beam chamber. Laser energy is then transmitted onto the penetrated surface of the stopper to fuse the stopper material and hermetically re-seal the stopper.

Disclosed herein is a packaging method for removing off-odors from irradiated foods using charcoal. In a package, foods are irradiated along with charcoal so as to remove the off-odors produced. The method can effectively remove off-odors from irradiated foods without influencing the sensory and physicochemical properties thereof, thereby allowing irradiation to be conducted and thus greatly contributing to food safety.

Embodiments of the present invention provide for a wrapping apparatus and associated methods. The wrapping apparatus may include a first holder for holding first items to be wrapped. The wrap is placed on a rotating table when the rotating table is rotated into a first position. One of the first items to be wrapped is moved from the first holder onto the wrap on the rotating table when the rotating table is rotated to a second position. A wrapping mechanism then wraps the first item in the wrap.

The present invention is related to an apparatus and method for irradiating a product package, comprising a radiation source directing a radiation beam along a beam direction towards said product package, conveying means for transporting said product package past said radiation source along a transport path, and reflecting means located on at least one side of the plane formed by said beam direction and said transport path. By adjusting the distance and angle of the reflecting means to the conveyor and beam, and improved dose uniformity ratio is obtained.
摘要:
A method for producing a polymeric film resistant to degradation during sterilization such as gamma irradiation is presented. The method includes the steps of minimizing the number of free radicals formed during sterilization through use of an inert gas and a reactant scavenger within a sterilization pouch, which reactant scavenger may be acid adsorbents which scavenge the acid by-products formed during irradiation. The films retain physical and mechanical properties with long-term storage. The films are particularly amenable for use as packaging laminates in pharmaceutical, food, semiconductor and medical device industries.

An apparatus, and related methods for sterilizing microorganisms in a container, the apparatus consists of the container including a blister formed therein and a backing material that together with the blister form a cavity in which is contained a contact lens and a preservative fluid. A flashlamp generates high-intensity, short-duration pulses of light for deactivating microorganisms within the container by illuminating the container with the pulses of light having been generated.

A flexible container is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments, separated by peelable seals, in which the diluents and medicaments are stored. The container is constructed of thermoplastic materials having high oxygen and moisture barrier properties which allows the container to be stored for extended periods of time without degrading the contents. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient. The seals are constructed to provide a non-linear resistance characteristic to hydraulic pressure, which causes the seal to peel open completely along its length. The container is folded-over along the line of one of the seals and also includes a locking tab and retaining slot to secure the bag in a folded-over condition.

Methods and apparatus for food product preservation by inactivation of microorganisms and/or enzymes by applying pulses of very intense, very short duration pulses of light in the visible and near visible frequencies to the surface of food products to be preserved. Also disclosed are packaging methods and apparatus utilizing such intense, short pulses of polychromatic, incoherent light.

An ultraviolet sterilizing apparatus includes a sterilization chamber defining an enclosed space and having an entrance and an exit, a roller conveyor arranged between the entrance and the exit for conveying products to be sterilized through the interior of the sterilization chamber, and a plurality of sterilizing ultraviolet lamps arranged about the path along which the products are conveyed. The apparatus is characterized in that some of the ultraviolet lamps are situated below the conveyance path, each of these ultraviolet lamps being interposed between mutually adjacent ones of the rollers in the roller conveyor and arranged far enough below the conveyance plane of the roller conveyor so as not to contact the products being conveyed. This ultraviolet lamp arrangement makes it possible to uniformly sterilize products over their entire surface without requiring that the products be turned over on the conveyor. The apparatus is further provided with auxiliary chambers each having an ultraviolet radiation shielding curtain suspended from an inlet and outlet of the apparatus to prevent ultraviolet rays from leaking out of the sterilization chamber.

An irradiator which can be incorporated within a packing house and a method of irradiating food in the packing house are disclosed. Food products are placed on spaced baskets and conveyed into an enclosure, through a irradiation chamber, and then outwardly from the enclosure. The food products are conveyed through tortuously arranged ductwork which serves to absorb radiation streaming upwardly. The radiation source is maintained underwater both during operation and shutdown, and no lifting of the radiation source is thus required. A portion of the conveyor is positioned within one or more casings and can be withdrawn, if necessary, to facilitate maintenance and repair.
