Plug adapted to be fixed by means of hot melt adhesive into an opening in a plate such as an automobile body
First Claim
1. A plug to be fixedly inserted within an opening of a plate, comprising:
- a body portion having an annular, flanged peripheral portion defined about said body portion so as to extend in a circumferential direction about said body portion;
hot melt adhesive means disposed upon an undersurface portion of said annular, flanged peripheral portion of said body portion for engaging a first surface of said late when said plug is inserted within said opening of said plate; and
at least one snap-fastener blade means for snap-engaging a second surface of said plate when said plug is inserted within said opening of said plate, said at least one snap-fastener blade means being flexibly secured to said body portion in a cantilevered manner by means of an attachment end fixed to said body portion at a first peripheral location in said circumferential direction, and having a free end portion thereof extending in a longitudinal direction of said blade means which is disposed parallel to said annular, flanged peripheral portion and which is located at a second peripheral location which is remote from said first peripheral location along said circumferential direction.

Abstract
A plug is adapted to be fixed by means of a hot melt adhesive into an opening in a plate. It comprises a molded plastics material body and a bead of hot melt adhesive deposited onto a peripheral surface of the body around a surface transverse to the peripheral surface. The body comprises at least one snap-fastener blade having an insertion ramp and a retaining lip such that the insertion ramp bears against the edge of the opening when the plug is placed on the latter, bends if pressure is then applied to the plug to press it into the opening, and expands thereafter with the lip facing a first side of the plate while the bead of adhesive faces a second side of the plate. The snap-fastener blade extends between an attachment end and a free end in a longitudinal direction parallel to the peripheral surface and to the transverse surface. The blade is therefore entirely on the second side of the plate when the plug is snap-fastened in place. The distance in the longitudinal direction between the attachment end and the free end is greater than the distance between the peripheral surface and the foot of the insertion ramp.

17. In combination, a plug and plate assembly comprising:
-
a plate having an opening defined herein wherein said opening is defined within said plate by means of a continuous, non-interrupted annular sidewall portion of said plate; and a plug to be fixedly inserted within said opening defined within said plate; said plug comprising a body portion; and
annular flanged peripheral portion defied about said body portion so as to extend in a circumferential direction about said body portion;
hot melt adhesive mean disposed upon an undersurface portion of said annular flanged peripheral portion of said body portion for engaging a a first surface of said plate when said plug is inserted within said opening of said plate; and
at least one snap-fastener blade means for snap-engaging a second surface of said plate when said plug is inserted within said opening of said plate, said at least one snap-fastener blade means being flexibly secured to said body portion in a cantilevered manner by means of an attachment end fixed to said body portion at a first peripheral location in said circumferential direction, and having a free end portion thereof extending in a longitudinal direction of said blade meanwhich is disposed parallel to said annular flanged peripheral portion and which is located at a second peripheral location which is remote from said first peripheral location along said circumferential direction. - View Dependent Claims (18, 19, 20)
