An elongated product delivery tube (310) contains a product diverting device (316) that evenly disperses the product, allowing a clean seal to be completed in a shorter time. An optional vibration device (318) helps to quickly place the product. Compared with the prior art, throughput has been increased, but it also facilitates the opening of packaging and marketing.
