Abstract
A method for providing an end-stop for a slider on a resealable thermoplastic bag is provided. The resealable thermoplastic bag includes a profile track having a first side panel and a second side panel. A clip having first and second legs is made to straddle the profile track such that the first leg of the clip being proximate to the first side panel and the second leg of the clip being proximate to the second side panel. One of the legs has an inward-facing protrusion for engaging a corresponding recess on the panel proximate thereto, such that the clip resists vertical motion on the profile track. The other of the legs of the clip is sealed to the panel proximate thereto.
Claims29
A method for providing an end-stop for a slider on a resealable thermoplastic bag, the resealable thermoplastic bag including a profile track, a first side panel and a second side panel, the method comprising:
- causing a clip having first and second legs to straddle the profile track, the first leg of the clip being proximate to the first side panel and the second leg of the clip being proximate to the second side panel, one of the legs having an inward-facing protrusion for engaging a corresponding recess on the panel proximate thereto, such that the clip resists vertical motion on the profile track;
- and
- sealing the other of the legs of the clip to the panel proximate thereto.
A clip for providing an end-stop for a slider on a resealable thermoplastic bag, the resealable thermoplastic bag including a profile track having a first side panel and a second side panel, the clip comprising:
- first and second legs permitting the clip to straddle the profile track, in such a manner that the first leg of the clip is proximate to the first side panel and the second leg of the clip is proximate to the second side panel, one of the legs having an inward-facing protrusion for engaging a corresponding recess on the panel proximate thereto, such that the clip resists vertical motion when the clip straddles the profile track;
- and
- the other of the legs of the clip being longer than the leg having the protrusion, and configured to permit being sealed to the panel proximate thereto.
A method for making a continuous stream of resealable slider bags from a length of profile track, the profile track associated with a first side panel and a second side panel, the method comprising:
- creating a laterally indented portion on the profile track at intervals along the track;
- inserting a slider onto the profile track at each indented portion and moving them to locations away from the indented portion;
- causing two clips, each having first and second legs, to straddle the profile track proximate to the indented portion, the first leg of each clip being proximate to the first side panel and the second leg of each clip being proximate to the second side panel, one of the legs of each clip having an inward-facing protrusion for engaging a corresponding recess on the panel proximate thereto, such that each clip resists vertical motion on the profile track;
- and
- sealing the other of the legs of each clip to the panel proximate thereto.
A method for providing an end-stop for a slider on a resealable thermoplastic bag, the resealable thermoplastic bag including a profile track having a first side panel and a second side panel, the method comprising:
- causing a clip having first and second legs to straddle the profile track, the first leg of the clip being proximate to the first side panel and the second leg of the clip being proximate to the second side panel, one of the legs having an inward-facing protrusion for engaging a corresponding area on the panel proximate thereto, such that the clip resists vertical motion on the profile track;
- and
- sealing the other of the legs of the clip to the panel proximate thereto.
A clip for providing an end-stop for a slider on a resealable thermoplastic bag, the resealable thermoplastic bag including a profile track having a first side panel and a second side panel, the clip comprising:
- first and second legs permitting the clip to straddle the profile track, in such a manner that the first leg of the clip is proximate to the first side panel and the second leg of the clip is proximate to the second side panel, one of the legs having an inward-facing protrusion for engaging a corresponding area on the panel proximate thereto, such that the clip resists vertical motion when the clip straddles the profile track;
- and
- the other of the legs of the clip being longer than the leg having the protrusion, and configured to permit being sealed to the panel proximate thereto.
A method for making at least one resealable slider bag from a length of profile track, the profile track associated with a first side panel and a second side panel, the method comprising:
- creating a laterally indented portion on the profile track;
- inserting a slider onto the profile track at the indented portion and moving the slider to a location away from the indented portion;
- causing a clips having first and second legs to straddle the profile track proximate to the indented portion, the first leg of the clip being proximate to the first side panel and the second leg of the clip being proximate to the second side panel, one of the legs of the clip having an inward-facing protrusion for engaging a corresponding area on the panel proximate thereto, such that the clip resists vertical motion on the profile track;
- and
- sealing the other of the legs of the clip to the panel proximate thereto.
