Floor marking tape
A floor marking tape has a structure that retains the adhesive under the tape to prevent the adhesive from being squeezed out from under the tape when the tape is in use on a floor. In one embodiment, the structure is a shoulder that defines a recess that holds the bulk of the adhesive. The shoulder prevents the adhesive from flowing out to the outer edge of the tape. The tape may have beveled edges that limit the unintentional lifting and delamination of the tape from the floor. The upper surface of the tape may be curved from edge-to-edge to limit dirt retention on the tape as well as allowing objects to slide over the tape.

the body of the floor marking tape having first and second lateral edge portions disposed in the longitudinal direction; each of the first and second lateral edge portions having an upper surface and a lower surface;
each of the first and second lateral edge portions having a width defined in a direction perpendicular to the longitudinal direction;
the upper surface of each lateral edge portion comprising an extension of the upper surface of the body;
the lower surface of each lateral edge portion being a flat coplanar extension of the lower surface of the body;
the entire body of each lateral edge portion being tapered with the upper surface of the first lateral edge portion extending to the lower surface of the first lateral edge portion and the upper surface of the second lateral edge portion extending to the lower surface of the second lateral edge portion;
each of the first and second lateral edge portions having a maximum height that is less than its width; and
an adhesive securing the lower surface of the body to the uppermost surface of the floor to establish a boundary.

9. The floor and boundary tape configuration of claim 7 , wherein the body has a maximum thickness and the recess has a maximum depth; the maximum thickness of the body being at least three times larger than the maximum depth of the recess.
10. The floor and boundary tape configuration of claim 1 , wherein the body has a central body portion disposed between the first and second lateral edge portions; each portion of the central body portion having a body thickness that is substantially greater than the adhesive thickness disposed directly under that portion of the central body portion.
11. A floor marking tape adhered to a floor wherein the floor marking tape establishes a boundary on the floor; the combination comprising:
a floor having an uppermost surface; the uppermost surface of the floor configured to support personnel and equipment thereupon;
a floor marking tape having a body that has an upper surface and a lower surface; the lower surface facing the uppermost surface of the floor to which the floor marking tape is adhered such that the body of the floor marking tape is disposed above the uppermost surface of the floor;
the body of the floor marking tape having a longitudinal direction;
the body of the floor marking tape having first and second lateral edge portions disposed in the longitudinal direction; each of the first and second lateral edge portions having an upper surface and a lower surface;
each of the first and second lateral edge portions having a width defined in a direction perpendicular to the longitudinal direction;
the entire body of each lateral edge portion being tapered with the upper surface of the first lateral edge portion extending to the lower surface of the first lateral edge portion to meet at a first junction and the upper surface of the second lateral edge portion extending to the lower surface of the second lateral edge portion to meet at a second junction;
the first and second junctions disposed on the uppermost surface of the floor such that the floor marking tape limits unintentional lifting of the floor marking tape from the floor;
each of the first and second lateral edge portions having a maximum height that is less than its width; and
an adhesive securing the lower surface of the body to the uppermost surface of the floor to establish a boundary.
