Our analysis of this patent is as follows:

United States Surgical Corporation’s patent US 5492304 A deals with Seal assembly for accommodating introduction of surgical instruments.
A seal assembly which includes a housing and a resilient first seal means associated with the housing. The first seal means is preferably a gasket having an aperture formed therein for receiving surgical instrumentation adapted to cooperate with a dilating means having an outer surface that had -with housing for dilating the aperture in the gasket. The first seal means and the dilating means adapted for relative movement therebetween, the first seal means and the dilating means assuming a first position wherein the aperture of the first seal means spaced from the dilating means and adapted to receive surgical instrumentation of a first diameter with minimal insertion force, and think that a second position in which the aperture of the first seal means that stretched around the outer surface of the dilating means for receiving surgical instrumentation of a second diameter greater than the first diameter with minimal insertion forces.

The Dowbrands L.P. patent solves the following problem:

This invention relates to food packaging film and food storage bag made from said film for storing, for example, such as vegetables and fruits. Particularly, this invention relates to flexible storage bag with a pattern of microholes specifically designed to allow overtaking in the bag to breathe in a controlled rate, as local pressure decline, in turn, reduces microbial (bacteria and mold) growth and yield mushiness (softness). The perforated bags of the present invention also control the weight loss of the stored produce, thus reducing the shriveling and wilting of unpackaged products.

Our analysis of this patent is as follows:

Dowbrands L.P.’s patent US 5492705 A deals with Vegetable containing storage bag and method for storing same.
A flexible films and flexible food bag for packaging such as vegetables and fruits which the film or bag with a plurality of microholes specifically designed to allow the breath in a controlled rate so that localized pressure and weight loss is minimized, which in turn reduces microbial (bacteria and mold) growth and decreasing mushiness (softness) respectively.
