Tampon pledget having a shaped tip and method of making same
View Patent ↗The present invention provides a tampon pledget having a shaped tip. The present invention further provides a method for forming a tampon pledget having a shaped tip. The method includes a cooling step after the formation of the shaped tip, which results in the minimization and/or prevention of deformation of the shaped pledget tip during the remainder of processing up until the end use by a consumer.
1. A process for manufacturing a pledget, the process comprising: positioning an absorbent member in the cavity of an oven chain link, moving said absorbent member disposed in the oven chain link through a heating device, said absorbent member having a forward end and a rear end; heating said absorbent member; introducing said heated absorbent member disposed in the oven chain link to a first member having a first orifice therein, said orifice having a concave surface therein with an orifice end; pushing said heated absorbent member to said orifice end, said forward end of said heated absorbent member forming a shaped tip; and cooling said heated absorbent member using a cooling device, wherein said cooling comprises introducing said oven chain link having said heated absorbent member therein to a cooling area after said pushing.
2. The process of claim 1 , wherein said first member is a head tooling die.
3. The process of claim 1 , wherein the cooling step is provided by said cooling device for providing a cooled surface, and further comprises the step of blowing a cooled air stream on said heated absorbent member to cool said shaped tip.
4. The process of claim 1 , wherein the cooling step is provided by said cooling device for providing a cooled surface, and further comprises the step of contacting said shaped tip with said cooled surface to cool said shaped tip.
5. The process of claim 1 , wherein the cooling step uses said cooling device and a fan, wherein said fan blows a cooled gaseous substance on said shaped tip through a plurality of nozzles.
6. The process of claim 1 , wherein said shaped tip is substantially tapered.
7. The process of claim 1 , wherein said cooling step hardens said shaped tip for preventing a deformation therefrom.
8. The process of claim 1 , wherein said cooling step is conducted at a temperature between about 30° F. to about 60° F.
9. The process of claim 1 , wherein the cooling step is conducted for a time between about 0.5 seconds to about 2 seconds.
10. The process of claim 1 , wherein said heating device is an oven operating at a temperature between about 200° F. to about 305° F.
11. A process for manufacturing a pledget, the process comprising: providing a heated absorbent member in an oven chain link, said heated absorbent member having a forward end, a rear end and an absorbent member body between said forward end and said rear end, said oven chain link having a wall surrounding a cavity, said cavity being a tubular shape having openings on each end, said cavity being sized to hold said heated absorbent member; introducing said heated absorbent member to a first member having a first orifice therein, said orifice having a concave surface therein; pushing said heated absorbent member through said cavity into said concave surface of said first member forming a shaped tip on said forward end of said absorbent member; and cooling said shaped tip with a cooling device, wherein said cooling comprises introducing said oven chain link having said heated absorbent member therein to a cooling area after said pushing.
12. The process of claim 11 , further comprising transferring said heated absorbent member that is cooled from said oven chain link to a transfer chain, wherein said cooling hardens or sets said shaped tip and prevents said shaped tip from deformation during said transfer.
13. The process of claim 11 , wherein said introducing said heated absorbent member to said first member comprises moving said oven chain link around a hot head drum with said heated absorbent member that is from an oven.
