  • the box lid assembly engages the box body only at the ribs and the edge region of the rigid outer lid when received at the one end of the box body to cover the opening.
  • the ribs are of a first polymer material
  • the compliant interference fastener having a web of a second polymer material, more rigid than the first polymer material, over which the first polymer material is overmolded and which connects the ribs, with a portion of the web sandwiched between the outer lid and the inner lid.
  • the box lid assembly defines an aperture in communication with the interior space, the aperture defined completely by the second polymer material of the compliant interference fastener.
  • the web is at least partially disposed in a recess defined in the rigid outer cover.
  • the inner and outer lids may be permanently secured to each other by adhesive, and the box body and the inner and outer lids may all be of wood.
  • the ribs each extend a distance, perpendicular to their length, about one-half a thickness of the rib measured in a direction of insertion into the box body.
  • the ribs are preferably of a polymer having a durometer of about 75 Shore A.
  • the ribs engage only central regions of the interior wall surfaces.
  • each rib engages an interior wall surface over a continuous length of about 3/8 times an overall distance along the interior wall surface between opposing comers of the box body.
  • Fig. 1 is a side view of a box with a lid on the bottom of the box.
  • Fig. 2 is a cross-sectional view, taken along line 2-2 in Fig. 1.
  • Fig. 3 is an exploded perspective view of the box and lid assemblies.
  • Fig. 4 is a top (inside) view of the lid assembly.
  • Fig. 5 is a side view of the lid assembly.
  • Fig. 6 is a top view of a compliant interference fastener of the lid assembly.
  • Fig. 7 is a cross-sectional view, taken along line 7-7 in Fig. 6.
  • Figs. 8A-8D are enlarged cross-sectional views of an interface between lid and box wall at one side of the lid, in different stages of engagement and separation.
  • a box 10 in the form of a toy coin bank has a box body 12 and a removable lid assembly 14.
  • the lid assembly is shown at the bottom of the box, forming a base upon which the box rests.
  • the lid may be disposed at the top of the box body, with the box inverted.
  • box 10 has an overall height H of about 100 mm.
  • box body 12 defines an interior space 16 between opposing walls 18 of the box body.
  • the box body is of generally square cross-section, with four similarly sized walls 18 connected at four comers of the box.
  • Each wall 18 has an interior wall surface 20. with the interior wall surfaces 20 of opposing walls 18 extending parallel from an opening 22 at one end of the box body (in this illustration, at the lower end of the box body).
  • the interior wall surfaces completely bound the four sides of the interior space, extending all the way to the comers of the box body.
  • An end frame 24 of the box 10 is mounted near the end of the box opposite the lid assembly 14 and defines an opening 26 therethrough for accessing the interior space 16 when the lid assembly 14 is in place.
  • the four w alls 18 of the box body are formed of w ood and are connected at right angle comers 28 defined by glued box joints, as shown in Fig. 3.
  • the box body is assembled with end frame 24 constrained within grooves defined in each of the four walls 18, to make a dimensionally stable structure.
  • lid assembly 14 is comprised of three structural components overlaying one another and permanently joined together by adhesive.
  • the box lid assembly 14 is adapted to be removably received at the end of the box body to cover the opening 22, and includes a rigid outer lid 32 of wood, a compliant interference fastener 34 of molded polymer nested in a recess 36 cut into the outer lid, and a rigid inner lid 38 of wood permanently secured to the rigid outer lid 32 with the interference fastener 34 sandwiched between the rigid outer lid and the rigid inner lid, to form the structure shown in Figs. 4 and 5.
  • the rigid outer lid 32 has an edge region 40 positioned to bear against the one end of the box when the box lid assembly 14 is covering the opening 22 (as shown in Fig. 2).
  • the compliant interference fastener 34 is secured to the outer lid 32 and has a total of four ribs 42, including tw o sets of two ribs extending in opposite lateral directions and exposed at the sides of the lid assembly.
  • the four ribs 42 are arranged to engage the interior wall surfaces 20 of the box body (Fig. 2) with the box lid assembly 14 received at the one end of the box body, with each rib 42 engaging to bear against the interior wall surface 20 of a respective one of the four walls 18 of the box body.
  • each rib 42 is of a limited length L of only about 32 mm, whereas the distance betw een opposing interior wall surfaces is about 81 mm.
  • the ribs are only about 3/8 as long as the interior wall surfaces against which they bear.
  • the ribs 42 do not extend to the comers of the box body when engaging the interior wall surfaces, but leave substantial portion of each wall unengaged and unsealed.
  • the ribs 42 function only as an interference fastening against the smooth interior wall surfaces to hold the lid assembly 14 on the box, and do not form any sort of seal.
  • compliant interference fastener 34 is molded of two polymers.
  • a web 44 of ABS polymer 45 has a central hub 46 and four spokes extending out to an octagonal rim 48.
  • TPU polymer 49 is overmolded onto the web at four of the eight segments of the rim to form ribs 42 of a durometer of 75 Shore A.
  • the TPU is overmolded to fill apertures in the rim segments, thereby securely interlocking the solidified TPU to the ABS w eb.
  • the hub 46 defines a 17 mm diameter central aperture 50 through the web, sized for inserting a finger to pull the lid assembly from the box.
  • Hub 46 extends axially from the web and has an outer diameter sized to fit in respective openings in the inner and outer lids (see Fig. 3), such that the ABS resin of the web forms a smooth inner surface through the lid assembly.
  • Figs. 8A through 8D sequentially show' the engagement and disengagement of a rib 42 against an interior wall surface 20 as the lid assembly 14 is received on, and removed from, the end of the box.
  • the ribs 42 first help to center the lid assembly 14 to the box body 12.
  • Each rib 42 extends out beyond the interior wall surface 42 to form an interference fit.
  • the ribs deflect away from the interior of the box, and stay in this deflected, stressed state as they slide along the interior wall surface until the outer box lid 32 rests against the end of the box body 12 (Fig. 8C).
  • the ribs 42 resist sliding along the interior box surfaces 20.
  • the durometer of the rib in relation to the static coefficient of friction between the rib and the interior wall surface and the amount of interference, is selected such that the rib deflection is reduced as the lid assembly is dislodged from the box body, and in some cases even inverted prior to being pulled from the box body.
  • the rib has a thickness of 1.0 mm along its length and extends from the adjacent TPU wall a distance of 2.0 mm.
  • the edges of the ribs are molded to have a radius of about 0.3 mm, and to also have a radius of about 0.3 mm where it joins the adjacent TPU wall.
