    摘要: A form-fill-and-seal (FFS) packaging machine is described wherein a zipper is attached to the package simultaneously with the sealing operation at the sealing and evacuation station. The attached zipper is thereafter welded in place at the zipper welding and cutting station. A zipper blank feeder and a channel-forming die with an impulse sealer are integrated into the sealing die of a packaging machine forming a combination work station. The zipper is installed at an existing work station and shares the existing lifting device. This enables the retrofitting of an FFS packaging machine to include a zipper attachment function without changing the footprint thereof. The combination work station forms a channel for the zipper blank between the thermoformed web and the lidstock. While the sealing die is providing a seal about the lid, the impulse sealer in the channel-forming die attaches the zipper to an initial attachment portion of the packaging film. Upon completion of the package, this initial attachment portion, if retained, becomes the tamper-indication portion of the package. Both the sealing and evacuation station and the zipper welding stations of this invention are of jacketed construction enabling the temperature control of the zipper blank throughout the installation procedures.

    摘要: A method of supporting a plastic container exposed to elevated temperatures during product filling and packaging to eliminate heat and internal pressure induced distortion, internal vacuum distortion, or structural failure. Plastic containers usually have a body with exterior configuration and a sealable open mouth. The invention provides a method of hot filling, pasteurising and retort processing of conventional containers during product filling where at least a portion of the container is confined in a support casing having an interior cavity mating the exterior configuration of the container body portion. The product is then introduced into the container, and the container mouth is sealed. A positive pressure is induced within the sealed container while the container is exposed to a product processing temperature. An unsupported PET container exposed to high heat and internal pressure variations would distort or fail. However, the external mating support casing together with positive internal pressure restrains the PET container during this period of high stress and low resistance thereby preventing distortion or failure. Afterwards, by cooling the container to a casing release temperature below the product processing temperature and then releasing the container from the casing, eliminates container distortion problems.

    摘要: A system for packaging of perishable food products involves initially packaging the food product in a receptacle containing an inert gas atmosphere and sealing a film to the receptacle. The inert gas atmosphere prevents deterioration of the food product subsequent to shipment from a central processing facility. The receptacle includes a sealing flange and a tab portion extending from the sealing flange, to which the film is sealed. To prepare the food product for display at a retail establishment, the tab and the film sealed thereto are removed from the package, to form an opening between the film and the receptacle. An atmosphere exchange operation is carried out through the opening, by inserting a nozzle through the opening and introducing an oxygen-containing gas into the receptacle cavity through the opening. The inert gas atmosphere initially contained within the receptacle is exhausted through the opening. Once the atmosphere exchange process has been carried out, the nozzle is withdrawn from the opening and the opening is closed by sealing the film to the receptacle. Introduction of the oxygen-containing gas into the receptacle cavity induces the desired oxygen “bloom” in a fresh meat food product, and in other food products replaces the inert gas atmosphere in preparation for display and consumption of the food product. The final configuration of the package as displayed to consumers has the same external appearance as prior art packages, leading to ready consumer acceptance while greatly enhancing product life and reducing spoilage associated with production and distribution of the food products from a central processing facility. The invention also contemplates a package and a receptacle construction for use in carrying out the described method.

    摘要翻译: 用于包装易腐食品的系统包括首先将食品包装在包含惰性气体气氛的容器中并将膜密封到容器。 惰性气体气氛防止从中央处理设备出货之后的食品劣化。 容器包括密封凸缘和从密封凸缘延伸的凸片部分,薄膜被密封到该凸缘部分。 为了准备用于在零售店展示的食品,将片状物和密封在其上的膜从包装中移出,以在膜和容器之间形成开口。 通过开口进行气氛更换操作,通过将开口插入喷嘴并通过开口将含氧气体引入到容腔中。 最初容纳在容器内的惰性气体气体通过开口排出。 一旦进行了气氛更换处理,喷嘴从开口中取出,并且通过将膜密封到容器来关闭开口。 将含氧气体引入容器空腔中引起新鲜肉类食品中所需的氧气“绽放”,并且在其它食品中替代惰性气体气氛以准备展示和消费食品。 向消费者展示的包装的最终结构具有与现有技术包装相同的外观,从而使消费者接受准备,同时极大地提高产品寿命并减少与中央处理设备的食品的生产和分配相关的腐败。 本发明还考虑了用于实施所述方法的包装和容器结构。
