Abstract
A reclosable package comprises opposing wall panels (16, 18) and a reclosable seal (14). The opposing wall panels are joined on three sides such as to create a receptacle space having a mouth at one end. The reclosable seal (14) extends along the one end and includes a first track and a second track. The first track includes a first reclosable element (26) and a first fin (28) portion extending downward from the first reclosable element (26) toward the receptacle space (22). The first track is joined to one of the wall panels. The second track includes a second reclosable element (32) and a second fin (34) portion extending downward from the second reclosable element toward the receptacle space. The second track is joined to the other of the wall panels. The first (26) and second (32) reclosable elements are releasably engageable to each other. In one embodiment, the first and second fin portions are joined to each other along a one-time breakable preferential area of weakness to prevent tampering with the package prior to being opened. In another embodiment, the mouth end is pleated and forms a one-time breakable preferential area of weakness.
Claims
AMENDED CLAIMS
[received by the International Bureau on 6 February 1998 (06.02.98); original claims 4, 11-21 cancelled; original claim 1 amended; remaining claims unchanged (2 pages)]
1. A reclosable package comprising: opposing wall panels joined on three sides such as to create a receptacle space having a mouth at one end; and a reclosable seal extending along said one end and including a first track and a second track, said first track including a first reclosable element and a first fin portion extending downward from said first reclosable element toward said receptacle space, said second track including a second reclosable element and a second fin portion extending downward from said second reclosable element toward said receptacle space, said first and second fin portions being joined to each other along a one-time breakable preferential area of weakness to prevent tampering with said package prior to being opened, said reclosable seal being free of pull flanges extending upward from said first and second reclosable elements which can be grasped and pulled apart to open said reclosable seal from a sealed form; and a slider mechanism slidably mounted to said reclosable seal for movement between a closed position and an open position, said first and second reclosable elements being engaged to each other while said slider mechanism is in said closed position, said first and second reclosable elements being disengaged from each other in response to movement of said slider mechanism to said open position.
2. The reclosable package of Claim 1, wherein said first and second fin portions are joined to each other along respective lower edges thereof.
3. The reclosable package of Claim 1, wherein said first and second fin portions are coextruded with each other so as to form a single continuous fin. 5. The reclosable package of Claim 1 , wherein a combination of said first and second fin portions has a generally U-shaped or V-shaped cross-sectional configuration.
6. The reclosable package of Claim 1, wherein said first fin portion is attached to an inner surface of said one of said walls and said second fin portion is attached to an inner surface of said other of said walls.
17
7. The reclosable package of Claim 1, wherein said preferential area of weakness is selected from the group consisting of a series of perforations, a score line, a thinned line, and a highly oriented region. 8. The reclosable package of Claim 1 , wherein said first reclosable element is a first profile and said second reclosable element is a second profile, and further including a slider mechanism slidably mounted to said first and second profiles for movement between a closed position and an open position, said first and second profiles being engaged to each other while said slider mechanism is in said closed position, said first and second profiles being disengaged from each other in response to movement of said slider mechanism to said open position.
9. The reclosable package of Claim 1, wherein said first fin portion is directly connected to one of said wall panels and said second fin portion is directly connected to the other of said wall panels. 10. The reclosable package of Claim 1 , wherein said first reclosable element is directly connected to one of said wall panels and said second reclosable element is directly connected to the other of said wall panels.
