Abstract

Abstract A container is formed from a pair of concave shell halves with each shell half having a small upper portion and a lower portion which is larger than the upper portion. The shell halves are connected by an integral hinge at their respective upper portions. The smaller upper portions are sized to be easily received in and encompassed by the fingers of a user. The lower portions are provided with straight edges which are disposed remote from the integral hinge. The shell halves are constructed so that they can be manipulated from their normally biased open, i.e., spread apart configuration to a closed configuration about animal excrement. As the shell halves are so manipulated the straight edges scrape the animal excrement into the container. In one embodiment when the shell halves are in their closed configuration the straight edges are in telescoping relationship and a locking structure is provided along at least the straight edges to lock the shell halves in their closed relationship thereby effectively sealing the container. In an alternative embodiment, the straight edges, when the shell halves are in the closed configuration, abut each other and a locking structure disposed on the edges of the shell halves locks the shell halves in their closed relationship.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 171 words
A hand operable scoop for collecting and disposing of animal excrement comprising: (a) a pair of concave shell halves each formed with smooth compound curving wall surfaces, said curves generated about two axes throughout said wall surfaces, each of said shell halves having a smaller upper portion and a lower portion larger than said upper portion, said smaller portions sized to be easily received in and encompassed by the hand of a user; (b) an integral hinge means connecting said pair of shell halves at their respective upper portions; (c) straight edges disposed on said lower portion remote from said hinge means; (d) finger receiving means disposed on each of said shell halves so that said shell halves may be manipulated about said hinge means from an open configuration to a closed configuration about animal excrement, while said straight edges scrape said animal excrement into said shell halves; and (e) locking means disposed on said shell halves to lock said shell halves in their closed configuration to form a sealed container.
Claim 2
Dependent Claim 171 words
A hand operable scoop for collecting and disposing of animal excrement comprising: (a) a pair of concave shell halves each formed with smooth compound curving wall surfaces, said curves generated about two axes throughout said wall surfaces, each of said shell halves having a smaller upper portion and a lower portion larger than said upper portion, said smaller portions sized to be easily received in and encompassed by the hand of a user; (b) an integral hinge means connecting said pair of shell halves at their respective upper portions; (c) straight edges disposed on said lower portion remote from said hinge means; (d) finger receiving means disposed on each of said shell halves so that said shell halves may be manipulated about said hinge means from an open configuration to a closed configuration about animal excrement, while said straight edges scrape said animal excrement into said shell halves; and (e) locking means disposed on said shell halves to lock said shell halves in their closed configuration to form a sealed container.
Claim 3
Dependent Claim 62 words
The hand operable scoop in accordance with claim 1 wherein said finger receiving means comprises elongated depressions on each of said shell halves which depressions are oriented substantially perpendicularly to said hinge means and bearing surfaces within each of said depressions constructed and arranged to engage said fingers so that said shell halves may be manipulated through corresponding manipulation of said fingers.
Claim 4
Dependent Claim 47 words
The hand operable scoop in accordance with claim 1 wherein said first and second shell halves are biased into said open configuration whereby said shell halves are urged against the fingers of the user as said first and second shell halves are manipulated into their closed configuration.
Claim 5
Dependent Claim 37 words
The hand operable scoop in accordance with claim 1 wherein said straight edges are in telescoping relationship when said first and second shell halves are closed and said locking means is adjacent at least said straight edge.
Claim 6
Dependent Claim 43 words
The hand operable scoop in accordance with claim 1 wherein said straight edges are in abutting relationship when said first and second shell halves are closed and said locking means is disposed on the side edges of said first and second shell halves.
