In this paper firstly, we generalize the concept of codismantlable graphs to\nhypergraphs and show that some special vertex decomposable hypergraphs are\ncodismantlable. Then we generalize the concept of bouquet in graphs to\nhypergraphs to extend some combinatorial invariants of graphs about\ndisjointness of a set of bouquets. We use these invariants to characterize the\nprojective dimension of Stanley-Reisner ring of special hypergraphs in some\nsense.\n
