Definitions

  • This invention relates to a test tube rack assembly featuring upper and lower test tube support members, and a base for removeably supporting said members.
  • Test tube racks are basic equipment in laboratories and the like and serve to hold test tubes during various analytical and processing procedures.
  • Catalog 283 published by Bel-Art Products, Inc., Pequannock, New Jersey, wherein a variety of test tube racks are illustrated and described.
  • test tube racks are generally of a unitary construction. This requires more storage space than is desireable and increases shipping costs, as the case may be. Further the test tube support portions of these racks are not removeable which detracts from their versatility in accommodating a variety of test tube sizes and desired holding capacities. Moreover, if the racks are of a molded plastic material as is common in the art, the molds for such unitary racks are costly and add to the ultimate cost of the rack.
  • test tube rack assembly of the present invention satisfies this need.
  • This invention contemplates a test tube rack assembly including a base which removeably supports upper and lower test tube support members.
  • the base is fabricated as a flat member having ends and sides which are bendable substantially normal to the bottom of the base.
  • the upper and lower support members have discretely spaced tabs which are received in snap-fit relation in corresponding discretely spaced apertures in the bent ends and sides of the base.
  • the bottom of the base is a flat open grid.
  • the upper and lower support members are flat open grids corresponding in size and pattern so that a plurality of test tubes fit through said grids for being supported by said upper and lower support members. Since the base and support members may be shipped and stored flat, shipping costs and storage space are reduced.
  • the upper and lower support members are thus remove­able, whereby the base can support a variety of said members having grids of a variety of corresponding sizes and patterns.
  • Base 2 has a solid circum­ferential frame 4 surrounding an open grid 6 which serves as the bottom of the base as will hereinafter become evident.
  • End members 8 and 10 extend from the one and the opposite ends of frame 4 and side members 12 and 14 extend from the one and the opposite sides of said frame.
  • Side members 12 and 14 each include a pair of U-shaped members 16 and 18 and 20 and 22, respectively.
  • U-shaped members 16 and 18 are in spaced relation and are disposed near the ends of side member 12 and
  • U-shaped members 20 and 22 are in corresponding spaced relation and are disposed near the ends of side member 14.
  • End members 8 and 10 have substantially rectangular relatively large openings 24 and 25, respectively, extending therethrough for purposes which will be hereinafter described.
  • End members 8 and 10 have a plurality (shown as four in number for illustration purposes) of horizontally and verti­cally aligned relatively small, substantially rectangular, discretely spaced upper and lower apertures such as 26.
  • U-­shaped members 16 and 18 of side member 12 and 20 and 22 of side member 14 likewise have a plurality (shown as four in number for illustration purposes) of horizontally and verti­cally aligned relatively small, discretely spaced substan­tially rectangular, upper and lower apertures such as 28.
  • Apertures 26 and 28 have a purpose which will be hereinafter described.
  • base 2 is molded as a flat member of a suitable plastic material such as polypropylene with a ten percent talc content for weighting purposes.
  • ends 8 and 10 and sides 12 and 14 are bent so as to be substantially normal to bottom 6 as shown in Figure 2.
  • ends 8 and 10 and sides 12 and 14 extend from base frame 4 so as to form a natural hinge therewith as at 15 and 17, whereby the aforenoted bending is facilitated as is well known in the plastics fabrication art.
  • a lower test tube support member is designated by the numeral 30 and an upper test tube support member is designated by the numeral 32.
  • Support members 30 and 32 include solid circumferential frames 34 and 36, respectively, surrounding open grids 38 and 40, respectively.
  • the size and pattern of grid 38 and the size and pattern of grid 40 must coincide as will be hereinafter more fully explained.
  • Frame 34 has a plurality of shouldered tabs 42 spaced circumferentially therearound and frame 40 has a corres­ponding plurality of like tabs 44 likewise spaced circum­ferentially therearound.
  • Tabs 42 and 44 are spaced so as to correspond to the spacing of lower and upper apertures 26 in base end members 8 and 10, respectively and lower and upper apertures 28 in base side members 12 and 14, respectively.
  • lower test tube support member 30 is disposed between base end members 8 and and base side members 12 and 14 so that tabs 42 are aligned with lower apertures 26 and 28. Thereupon tabs 42 are snapped into said apertures 26 and 28 so that lower support member 38 is supported on its ends and sides by the ends and sides of base 2.
  • upper test tube support member 32 is disposed between base end members 8 and 10 and side members 12 and 14 so that tabs 44 are aligned with upper apertures 26 and 28, whereupon said tabs are snapped into said apertures so that upper support member 40 is supported on its ends and sides by base 2 above lower support member 30.
  • the spacing and pattern of lower and upper support member grids 38 and 40 must correspond so that test tubes to be supported thereby are axially displaced first through upper support member grid 40 and then through lower support member grid 38.
  • the spacing and pattern of base grid 6 need not correspond to that of grids 38 and 40 since the purpose of grid 6 is merely for draining or the like as will now be understood by those skilled in the art.
  • Openings 24 and 25 in end members 8 and 10 of base 2 are for handling purposes, whereby the rack assembly can be easily grasped.
  • base member 2 provided as aforenoted, support members 38 and 40 may be removeably assembled to the base member.
  • base member 2 accommodates a variety of pairs of lower and upper support members such as 38 and 40, each pair having a different but corresponding grid spacing and pattern to support more or less test tubes of larger or smaller sizes, as the case may be.
  • base member 2 lower support member 38 and upper support member 40 may be molded as flat members to reduce mold costs. Further, these members may be stored and shipped in the flat state to reduce required storage space and shipping costs as will now be understood.
  • the test tube rack as described is easily cleaned and is readily autoclavable as is desirable.
