Abstract
Abstract An individual sprinkle-packet for salt, pepper, sugar and the like is in the class comprising a pocketed plastic sealed along its edges to a paper backing, which can be bent back along a given line to rupture the plastic and provide one or more sprinkling openings. This invention, in preferred form, provides a pocket tapering and reducing to a narrow neck. Along the longitudinal center line of the neck, the plastic is depressed to form an inward rib which stiffens the neck, and supports its humped portions to ensure rupturing. The rib portion extends slightly into the pocket body, so that breakage adjacent to the pocket forms two small sprinkling apertures.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
89 words
A sealed dispensing packet of bend-to-rupture type comprising a pocketed face sheet sealed peripherally to a backing sheet, the pocketed face sheet having a narrow imperforate neck narrower than the pocket extending from the pocket, the neck having a longitudinal groove-rib separating it into longitudinally extending portions communicating with the pocket and of substantially non-increasing cross section with increasing distance from the pocket; said neck with its groove-rib being stiff whereby, when the neck is bent backwardly, rupture substantially at the junction of the neck and pocket is ensured.
Claim 2
Dependent Claim
89 words
A sealed dispensing packet of bend-to-rupture type comprising a pocketed face sheet sealed peripherally to a backing sheet, the pocketed face sheet having a narrow imperforate neck narrower than the pocket extending from the pocket, the neck having a longitudinal groove-rib separating it into longitudinally extending portions communicating with the pocket and of substantially non-increasing cross section with increasing distance from the pocket; said neck with its groove-rib being stiff whereby, when the neck is bent backwardly, rupture substantially at the junction of the neck and pocket is ensured.
Claim 3
Dependent Claim
119 words
A sealed dispensing packet of bend-to-rupture type comprising a pocketed face sheet sealed peripherally to a backing sheet, the pocketed face sheet having a narrow imperforate neck narrower than the pocket extending from the pocket, the neck having a longitudinal groove-rib separating it into longitudinally extending portions communicating with the pocket and of substantially non-increasing cross section with increasing distance from the pocket; said neck with its groove-rib being stiff and of substantially less depth than the pocket and the groove-rib extending into the pocket beyond its junction with the neck, whereby, when the neck is bent backwardly, rupture substantially at the junction of the neck and the pockeT is ensured, with the formation of plural small pour openings.
Claim 4
Dependent Claim
119 words
A sealed dispensing packet of bend-to-rupture type comprising a pocketed face sheet sealed peripherally to a backing sheet, the pocketed face sheet having a narrow imperforate neck narrower than the pocket extending from the pocket, the neck having a longitudinal groove-rib separating it into longitudinally extending portions communicating with the pocket and of substantially non-increasing cross section with increasing distance from the pocket; said neck with its groove-rib being stiff and of substantially less depth than the pocket and the groove-rib extending into the pocket beyond its junction with the neck, whereby, when the neck is bent backwardly, rupture substantially at the junction of the neck and the pockeT is ensured, with the formation of plural small pour openings.
Claim 5
Dependent Claim
140 words
A sealed dispensing packet of bend-to-rupture type comprising a pocketed face sheet of plastic sealed peripherally to a backing sheet, the pocketed face sheet having a narrow imperforate neck narrower than the pocket extending from the pocket, the neck having a longitudinal groove-rib separating it into longitudinally extending portions communicating with the pocket and of substantially non-increasing cross section with increasing distance from the pocket; said neck with its groove-rib being stiff and of substantially less depth than the pocket and the groove-rib extending into the pocket beyond its junction with the neck, and the groove-rib, in the vicinity of the juncture of the neck and the pocket, extending close to the backing to prevent collapse of the plastic during bending, whereby, when the neck is bent backwardly, rupture substantially at the junction of the neck and pocket is ensured.
Claim 6
Dependent Claim
140 words
A sealed dispensing packet of bend-to-rupture type comprising a pocketed face sheet of plastic sealed peripherally to a backing sheet, the pocketed face sheet having a narrow imperforate neck narrower than the pocket extending from the pocket, the neck having a longitudinal groove-rib separating it into longitudinally extending portions communicating with the pocket and of substantially non-increasing cross section with increasing distance from the pocket; said neck with its groove-rib being stiff and of substantially less depth than the pocket and the groove-rib extending into the pocket beyond its junction with the neck, and the groove-rib, in the vicinity of the juncture of the neck and the pocket, extending close to the backing to prevent collapse of the plastic during bending, whereby, when the neck is bent backwardly, rupture substantially at the junction of the neck and pocket is ensured.
