Patent number: 7904996Abstract: A slider is adapted for use with a reclosable fastener for bags containing material. The reclosable fastener includes a first track and a second track. The first track includes a first profile, while the second track includes a second profile. The first and second profiles are releasably engageable to each other. At least one of the first and second profiles has an interior portion. The slider comprises a body that includes a top, a first side, a second side and a separation member on an underside of the top. The separation member is adapted to open and close the fastener and includes a slider finger that extends generally downwardly from the top. The slider finger extends into an interior portion of the first profile so as to assist in removing material trapped in the interior portion of the first profile when closing the reclosable fastener.Type: GrantFiled: December 29, 2009Date of Patent: March 15, 2011Assignee: Pactiv CorporationInventors: David V.

Patent number: 7316641Abstract: A reclosable package comprises first and second opposing body panels, a reclosable seal and a one-time breakable element. The reclosable seal extends along one end and includes first track and second tracks. The first track includes a first fin portion and a first reclosable element. The first fin portion has a first end and a second end that is further from the first reclosable element. The one-time breakable element comprises first and second sections and initially extends from the first fin portion to the second fin portion. Each of the first and second sections extends upwardly and inwardly from near the respective second ends of the first and second fin portions so as to form a generally inverted U-shaped or V-shaped cross-sectional configuration. The first and second opposing body panels are attached to respective first and second sections of the one-time breakable element.Type: GrantFiled: March 15, 2006Date of Patent: January 8, 2008Assignee: Pactiv CorporationInventors: Gary E.
