Abstract
A device for exercising a living hinge of an article and/or closing a lid of a cap while the article or cap is in a mold for forming the article or cap. The device includes a finger which slides between the mold sections, and, in the process, engages a portion of the article or the lid, rotates the portion or lid about the hinge, and in the case of the cap, snaps the lid shut. In an alternate preferred embodiment, when the finger reaches a predetermined point it pivots toward the female mold section to snap the lid tightly shut.
Claims16
A device for closing a lid of a cap while in a mold for forming said cap, said lid being pivotably connected to said cap by a hinge, said device comprising:
- a finger including a portion adapted for engagement with said cap;
- means for slidably connecting said finger to said mold, said finger being able to slide transverse to the axis of said hinge, said connecting means being oriented to enable said finger portion to engage said lid and rotate said lid about said hinge as said finger slides;
- and
- means for driving said finger.
A device for closing a lid of a cap while in a mold for forming said cap, said lid being pivotably connected to said cap by a hinge, said device comprising:
- a finger including a roller adapted for engagement with said lid;
- means for slidably connecting said finger to said mold, said finger being able to slide transverse to the axis of said hinge, said connecting means being oriented to enable said finger roller to engage said lid and rotate said lid about said hinge as said finger slides;
- and
- means for driving said finger.
In a mold for forming a cap having a lid, said lid being pivotably connected to said cap by a hinge, a device for closing said lid while said cap is in said mold comprising:
- a finger including a portion adapted for engagement with said lid;
- means for slidably connecting said finger to said mold, said finger being able to slide transverse to the axis of said hinge, said connecting means being oriented to enable said finger to engage said lid and rotate said lid about said hinge as said finger slides;
- and
- means for driving said finger.
A device for closing a lid of a cap while in a mold section for forming said cap, said lid being pivotably connected to said cap by a hinge, said device comprising:
- a finger having a roller adapted for engagement with said lid;
- a slide assembly connected to said finger and slidably connected to said mold section to slide transverse to the axis of said hinge and parallel to a surface of said mold section, said assembly being oriented to enable said roller to engage said lid, rotate said lid about said hinge, and close said lid as said finger slides;
- and
- means for driving said finger.
A device for exercising a living hinge of an article in a mold for forming said article, said device comprising:
- a finger including a portion adapted for engagement with said article;
- means for slidably connecting said finger to said mold, said connecting means enabling said finger to slide transverse to the axis of said hinge, said connecting means being oriented to enable said finger to engage a portion of said article and rotate said article portion about said hinge as said finger slides;
- and
- means for driving said finger.
A device for closing a lid of a cap while in a mold section for forming said cap, said lid being pivotably connected to said cap by a hinge, said device comprising:
- a finger having a portion adapted for engagement with said lid;
- a slide assembly connected to said finger and slidably connected to said mold section to slide transverse to the axis of said hinge and parallel to a surface of said mold section, said assembly being oriented to enable said finger portion to engage said lid, rotate said lid about said hinge and close said lid as said finger slides;
- and
- means for driving said finger.
In a mold for forming articles having a living hinge, a device for exercising said hinge comprising:
- a finger including a portion adapted for engagement with said article;
- means for slidably connecting said finger to said mold, said connecting means enabling said finger to slide transverse to the axis of said hinge, said connecting means being oriented to enable said finger to engage a portion of said article and rotate said article portion about said hinge as said finger slides;
- and
- means for driving said finger.
