Claim 1
Independent Claim
237 words
A hand-held receptacle for storing pourable contents comprising: (a) receptacle storage means comprising a storage portion and a generally tapered end portion through which contents stored therein may be discharged, the generally tapered end portion having a top and a base; (b) dual opening means arranged on said generally tapered end portion, said dual opening means being comprised of a first pre-defined breaking point situated toward the top of the tapered end portion, and a second pre-defined breaking point situated toward the base of the tapered end portion, said second pre-defined breaking point being located proximate said storage portion, said first and second breaking points providing a user with the option of releasing the contents by the application of a twisting or snapping motion to said first breaking point, or by the application of pressure to the second breaking point to break open the receptacle at one of the breaking points as desired; (c) said second breaking point being an abrupt neck portion of a small diameter than the tapered end portion said abrupt neck portion having a wall extending between a pair of opposed surfaces on the tapered end portion, said opposed surfaces extending radially with respect to the axis of the tapered portion; and (d) spaced web members adjoining both the wall of the neck portion and the opposed surfaces for strengthening the neck portion and determining the direction of breakage of the neck portion.
