| Some embodiments of the present disclosure include a device for protecting an upper exposed edge of a roll of paper products, such as paper towels or toilet paper, situated on a vertical dispenser. The device may include a substantially circular protector having an outer circumference and an inner orifice concentrically aligned with the outer circumference, the inner orifice being configured to align with a central opening in the roll of paper products. In some embodiments, the device may further include die cut triangles extending into the inner orifice, the die cut triangles configured flex into a position to secure the protector in place. | ||||||

| An edge protector for rolled materials and method of making thereof is disclosed. The edge protector includes a base substrate having a front surface and a back surface. The base substrate has an elongated lower portion and a plurality of fingers extending from one portion of the lower portion. The plurality of fingers is configured and arranged to fold substantially ninety degrees inwardly from the lower portion. A polymer coating is applied to at least one of the front surface and the back surface of the base substrate. | ||||||

| Embodiments of the present invention provide a cargo guard that is readily coupled to and/or removed from a binding strap, and further readily adapted to be repositioned with respect to the strap. The cargo guard may include one or more segments and/or one or more retainers. | ||||||
| 175 | Thread protector for use on pin end of oilfield tubulars | US10689913 | 2003-10-21 | US07159619B2 | 2007-01-09 | Burney J. Latiolais, Jr.; Johnny Firmin Elkins; Keith T. Lutgring; John K. M. Saichuk; Braxton I. Moody, V; Samuel P. Hawkins, III |
| A cylindrical ring sized to slide over the box end of an oilfield tubular having a given external diameter, has a shoulder at one its ends and a sidewall along its length. The sidewall has a circumferential groove about its interior surface housing a band which can be made tight against the exterior surface of the oilfield tubular by a latch, accessible through a slot in the sidewall, and which becomes even tighter if the tubular attempts to escape from the band. In a first orientation, the cylindrical ring is used as a load ring. By turning the cylindrical ring upside down, the cylindrical ring is used as a thread protector for the pin end of the tubular. | ||||||
| 176 | Casing thread protector | US215696 | 1994-03-22 | US5524672A | 1996-06-11 | Donald E. Mosing; Charles Sodha |
| A thread protector has a toroidal body of elastomer with a bore to accept a pipe end and a metal band and clamp arrangement extending around its periphery. The body is cut through one side to allow the body to expand peripherally. The bore accepts the end of a pipe with threads to be protected when the periphery is expanded and grips the pipe with the bore when the clamp closes the cut and shrinks the bore. To increase unit loading to force more elastomer of the body into thread grooves the bore has projections for gripping pads, or is recessed radially to produce gripping pads. The pads, which may be replaceably attached, reduced area increases deformity under clamping pressure and increases the force required to dislodge the protector from threads. The metal band is removable from an open peripheral groove or an optional arcuate tunnel partially encircling the pad body. | ||||||
| 177 | Pre-installation liquid level gauge assembly with thread protector | US46091 | 1993-04-12 | US5311776A | 1994-05-17 | Lloyd R. Morris |
| A pre-installation liquid level gauge assembly is provided which comprises a fitting with a threaded outer surface and a thread protector friction fit over the threaded outer surface. The thread protector comprises a sleeve portion and a shoulder portion extending radially inwardly to protect the end of the fitting and prevent the sleeve portion from sliding up the fitting to expose some of the lower threads. The shoulder portion defines a hole that is larger than the outer diameter of the passage in the fitting so that the thread protector does not interfere with the insertion of an extension piece into the passage in the fitting. The thread protector includes a tab and a scored line extending from the tab to the edge of the hole defined in the shoulder portion such that the tab can be pulled to totally split the thread protector to allow ready removal of the thread protector from the fitting. | ||||||
| 178 | Flange protector having integral connectors | US17435 | 1993-02-12 | US5265752A | 1993-11-30 | Donald C. Olson |
| A flange disc for protecting a flange having an inner annular machined surface surrounded by an outer surface with bolt holes extending through the outer surface and opening to a back surface opposing the outer surface, includes: a disc of flexible material having a size corresponding to a size of the outer surface of the flange to selectively cover the inner surface, outer surface and bolt holes, the disc defining a disc plane; and a plurality of connectors symmetrically located about a periphery of the disc at locations corresponding to at least some of the bolt holes, the connectors being integral with the disc and having, at one end, a resilient hinge portion and, at an opposite end, an engagement portion for engaging the corresponding bolt hole, the connectors rotating about the hinge portion between a transport position in which the engagement portion is in the disc plane and an engagement position in which the engagement portion is angled with respect to the disc plane for engaging the bolt hole. | ||||||
| 179 | Foldable multi-ply shock-absorbing edge protector | US498556 | 1990-03-26 | US5040684A | 1991-08-20 | John R. Knowles |
| The edge protector of the present invention is made of a plurality of sheets of inexpensive cardboard or linerboard cut into sections and laminated in a flat configuration. The laminations include at least one sheet which is continuous and provides a hinge portion, at least one sheet which is flexible and provides a stop--similar to a leaf spring. Protective laminates are disposed between the continuous member and the spring-like member and include a central portion and at least one leg portion. The leg portion can be pivoted about an axis in the continuous member, away from and at an angle to the central portion, thereafter to be held in angular disposition (that could vary in angular disposition restricted only to products' natural restrictions) with regard to the central portion by the spring-like portion. The edge protector of the present invention is particularly suited for protecting the edges of a large range of equipment such as furniture, desk-tops during the shipment or movement of such equipment or furniture. The channel of the present invention, when constructed, is flat, but when "set up", would be primarily an "L"-shape or "U"- shape configuration. But certainly not restricted to these configurations. They could be box-shaped, hexagonal, etc., limited only to a practical application of the spring hinge and hold concept. | ||||||
| 180 | Interior core protector | US533460 | 1990-06-05 | US4995512A | 1991-02-26 | Henry L. Liebel |
| An interior core protector for positioning about the inner circumference of a coil of material having a core to protect the material from damage including a rigid preformed angle bendable into an annulus having a diameter approximating the diameter of the core and an annular retaining disk having right angle legs in which the preformed angle is retained. The disk with annular preformed angle therein are receivable in the core of the coil of material providing protection to the coil about its entire circumference. | ||||||
