Definitions

  • This invention relates to the preservation of photographs, and, more specifically, to reducing the presence, in photograph albums and scrapbooks, of chemical agents harm ⁇ ul to photographs.
  • a very popular style of loose-leaf photograph album is manufactured and sold under the trademarks CREATIVE MEMORIES® and WEBWAY® by The Antioch Company of Yellow Springs, Ohio.
  • This style of loose-leaf photograph album includes a pair of covers enfolding a plurality of pages. The covers and the pages are laced together by means of straps. The straps thread through hinge elements projecting from the leaves and through slots in the covers. The end portions of the straps are frictionally held by means of cover holders positioned on opposite sides between the outer leaves and the covers.
  • kits for assembling a loose-leaf photograph album comprising one or more (most preferably two or three) flexible straps; a plurality of pages; and a pair of covers.
  • Each page of the plurality of pages defines at least one projecting hinge element so dimensioned to receive the straps.
  • Each cover of the pair of covers defines cover slots positioned and dimensioned to receive the flexible straps to bind the pair of covers to the plurality of pages.
  • the flexible straps comprise a polymer substantially free of halogen.
  • the halogens, Group Vila on the periodic chart, include highly electronegative elements such as fluorine and chlorine.
  • the flexible straps comprise low density polyethylene.
  • PVC contains atoms of chlorine, a halogen. It has been discovered that the PVC used in such straps can break down over time to release hydrochloric acid (HC1). Without wishing to be bound by any theory of operation, it is believed that the effects of heat, ultraviolet radiation, mechanical stress and air pollution can all contribute to the breakdown of the PVC. In addition, the acid released in the process of breaking down the PVC can contribute to the further breakdown of the PVC, thereby tending to accelerate the process. Additives such as plasticizers and stabilizers have been used to improve the physical properties of PVC polymer materials.
  • stabilizers such as metal salts have been added to neutralize the agents released in the process of breaking down PVC so as to reduce the effect of those agents in accelerating the process.
  • low molecular weight plasticizers such as phthalates have been added to increase the flexibility of the polymer material, since unplasticized PVC resin tends to be too rigid for use in straps for photograph albums or scrapbooks.
  • stabilizers and plasticizers do not bond with the polymer chains; under appropriate circumstances, they can move relative to the polymer chains which define the structure the straps.
  • Both the hydrochloric acid released by the breakdown of the PVC, and the stabilizers, plasticizers and other additives used in the PVC materials pose threats to the preservation of photographs stored in such photograph albums or scrapbooks. Under appropriate conditions, these agents are capable of leaving the straps and interacting with the photographs, thereby potentially discoloring those photographs.
  • the straps of photograph albums or scrapbooks formed in accordance with the present invention comprise polymer materials substantially free of halogen.
  • Many such polymer materials, especially those comprising polyethylene, are highly stable under ordinary environmental conditions. Even if these polymers were to break down, however, they contain no halogen atoms in their structural formulae. Consequently, the strong conjugate acids of such halogen atoms do not form if the polymer breaks down.
  • the flexible straps of photograph albums or scrapbooks formed in accordance with the invention may comprise polyurethane, which likewise is fairly stable and does not include halogen atoms in its structural formula.
  • Fig. 1 is a schematic view showing the parts of a photograph album or scrapbook in accordance with the present invention, with a portion of one cover broken away to show details of the binding;
  • Fig. 2 is a top plan view of a strap for the photograph album of Fig. 1 , the bottom plan view being a mirror image thereof;
  • Fig. 3 is a side elevational view of the strap of Fig. 2, the opposite side elevational view being a mirror image thereof.
  • a preferred loose-leaf photograph album or scrapbook 10 includes a pair of laminated padded covers 12 and 14 enfolding a plurality of pages 16.
  • the covers 12, 14 and the pages 16 are laced together by means of straps 18 and 20.
  • the straps 18, 20 are received through sets of aligned hinge elements (collectively 22 and 24), preferably in the form of stitches, which project from the pages 16; and through cover slots 26 (only one shown) in the covers 12, 14.
  • the cover slots 26 on each of the covers 12, 14 bear substantially the same spacial relationship to each other that each hinge element 22 bears to the other hinge element 24 projecting from the same page 16, thereby facilitating the lacing of the straps 18, 20 through the hinge elements 22, 24 and the cover slots 26.

  • the straps 18, 20 and the hinge elements 22, 24 preferably are covered by a removable spine (not shown) having ends which fit into pockets 38 (only one shown) defining recesses in the covers 12, 14.
  • the straps 18, 20 frictionally engage the cover holders 34, 36 so as to bind the covers 12, 14 and the pages 16 into a photograph album or scrapbook 10.
  • the spine (not shown), the straps 18, 20 and the cover holders 34, 36 are removable to permit additional pages (not shown) to be laced into the album 10.
  • a preferred strap 18 in accordance with the invention consists of a polymeric band or strip having a length dimension 50 and a width dimension 52.

  • an upper surface 60 of the preferred strap 18 is roughened to increase friction between the strap 18 and the cover holders 34, 36.
  • the preferred strap 18 also has a height dimension 70 which is small compared to the length dimension 50 and the width dimension 52 (Fig. 2). Most preferably, the height and width dimensions 52 (Fig. 2), 70 are selected so that the strap 18 fits easily through the hinge elements 22, 24 and the cover slots 26 but frictionally engages the cover holders 34, 36.
  • the configuration of the preferred strap has been described in detail, the configuration is not critical to the present invention.
  • the preferred strap 18 is formed by molding a translucent low density polyethylene polymer material.
  • the preferred low density polyethylene resin for use in the strap of the present invention is Polyethylene 9931 Low Density resin, available from Dow Chemical Company of Midland, Michigan. Although this resin produces straps having just enough flexibility to be roughly serviceable in photograph album or scrapbook binding, it is desirable to add an elastomer such as ENGAGE Polyolefin Elastomer (an ethylene alpha-olefin copolymer), available from DuPont Dow Elastomers L.L.C. of Wilmington, Delaware, to increase the flexibility of the strap at room temperature.
  • ENGAGE Polyolefin Elastomer an ethylene alpha-olefin copolymer
  • An especially preferred strap is molded from a copolymer resin comprising approximately 80 wt% Polyethylene 9931 Low Density resin and 20 wt% ENGAGE Polyolefin Elastomer. Neither Polyethylene 9931 Low Density resin nor ENGAGE
  • Polyolefin Elastomer are believed to contain substantial amounts of halogens or halogenated compounds.
  • the stability of the preferred polymeric material, and the absence of halogen and halogenated compounds from the material reduces the likelihood that the preferred polymeric material will break down to release acids capable of discoloring photographs stored in the photograph album or scrapbook 10.
  • Various changes or modifications in the invention described may occur to those skilled in the art without departing from the true spirit or scope of the invention.
  • the above description of preferred embodiments of the invention is intended to be illustrative and not limiting, and it is not intended that the invention be restricted thereto but that it be limited only by the true spirit and scope of the appended claims.

Abstract

L'invention concerne un nécessaire destiné à assembler un album de photographies ou de coupures (10) à feuilles volantes. L'album de photographies ou de coupures préféré (10) comprend une paire de couvertures (12, 14) enserrant plusieurs pages (16). Les couvertures (12, 14) et les pages (16) sont assemblées au moyen d'une au moins, et de préférence deux sangles souples (18, 20), qui passent à travers des éléments charnières (22, 24) se développant à partir des pages (16) et à travers des fentes (26) pratiquées dans les couvertures (12, 14). Les sangles (18, 20) sont, de préférence, retenues par un engagement frictionnel avec des porte-couvertures (34, 36), positionnés sur des côtés opposés entre les pages extérieures et les couvertures (12, 14). Les sangles préférées (18, 20) sont constituées d'un matériau polymère ne renfermant sensiblement pas d'halogène, de préférence d'un matériau comprenant du polyéthylène basse densité. L'absence d'halogène dans de tels matériaux polymères réduit la probabilité, qu'à la dégradation des matériaux polymères, le relargage d'agents soit néfaste à la qualité des photographies de l'album ou à celle de coupures rangées dans l'album (10).
