DESCRIPTION:
BRIEF SUMMARY
The present invention is concerned with bulk containers intended to accommodate fluidizable products, and in particular with bulk containers intended for accommodating fluidizable products, having sizes of more than 200 liters capacity.
Owing to an increasing rationalization in all industrial fields, products are packed and transported in increasingly large units. However, this trend to accept larger-sized units not only is hampered by the fact that the manufacture of large-sized containers is liable to involve difficulties, but also by the problem occurring at the receiving end, residing in that the product supplied in a large container, in accordance with the requirements at the receiving end, will have to be discharged for weeks on end. However, in respect of delicate organic products, such as foodstuffs, the discharge dragging on for weeks involves the risk that the product at least in part is bacterially decomposed, hence, becoming unfit for human consumption.
It is the object of the present invention to provide a bulk container appropriate for fluidizable products which is easy to manufacture and prepare, envolving low manufacturing costs, and which exhibits a strength appropriate for transportation, permitting a substantially complete discharge of the product and safeguarding that also delicate organic products, such as foodstuffs, can be dispensed for weeks on end without affecting the product quality.
In the practice of the invention, this is achieved in that a foil bag is provided, sealed together from individual foil webs, with the foil bag being accommodated in rigid envelope and comprising a loading opening and an outlet means disposed in the bottom part of the foil bag and aseptically sealing the foil bag against the environment, with the outlet means penetrating the envelope and comprising a draining tongue rigidly connected to the foil bag, and a discharge mechanism mountable thereon.
The bulk container as suggested by the invention enables a major amount of a foodstuff to be dispensed in partial amounts for weeks on end with no risk to the foodstuff in the container to be spoilt, thereby permitting foodstuffs to be withdrawn and transported in major amounts thus achieving substantial rationalization and a noteable reduction in material requirements envolved with product packaging.
The configuration of the bulk container as suggested by the invention to which reference will be made in closer detail in the following, permits an easy manufacture and preparation and a safe product transport, with a sterile sealing of the foil bag required for maintaining the product quality being at any time safeguarded by the outlet means, it being readily possible to package product quantities in amounts of more than 1000 liters. During transportation and storage of the, sterile sealing of the outlet means is solely effected by the draining tongue. For this purpose, a closure plate of plastic material is welded thereinto, which will be opened for dispensing purposes. The easiest alternative to manufacture a closure plate of this type is provided by welding the draining tongue made of plastic material and being of a substantially circular configuration directly on the foil bag made of foil. However, according to a preferred embodiment of the draining tongue as suggested by the invention, the draining tongue is to be closed by a separate closure plate envolving the substantial advantage that the connection between the draining tongue and the foil of the foil bag can be configured in a substantially more favorable manner thereby enabling, as described in the following, an advantageous operation of said outlet mechanism. Another advantage envolved with the draining tongue to be preferred according to the invention resides in that the thickness of the closure plate can be selected irrespective of the thickness of the foil bag. The additional advantages arising therefrom will also be described in the following. As the foil bag, in the practice of the invention, in collapsed condition, can be placed into the envelo
