PACKAGE FOR GLASSWARE 5 Sheets-Sheet 5 Filed March 5, 1965 United States Patent.
3,243,037 PACKAGE FOR GLASSWARE Paul R. Luertzing, Vineland, N.J., assignor to Lurex Manufacturing Company, Vineland, N.J., a corporation of New Jersey Filed Mar. 3, 1965, Ser. No. 436,745 1 Claim. (Cl. 206-1) The present invention relates to glassware packaging and more particularly relates to a novel package of the type suitable for packing chemical glassware and the like.
Glassware utilized in chemical laboratories is subject to breakage because of the odd shapes of the various pieces, and the inability to store the glassware or set it in a position where it cannot be inadvertently broken.
Although packaging kits are presently available on the market for glassware, due to the odd shapes and sizes of chemical glassware the package is either overly large or skimpy in design and adds to the danger of the glassware being broken as well as the difliculty encountered in storage.
In view of the above, it is an object of the present invention to provide an inexpensive package for glassware, which package is strong and durable in construction and yet lightweight and easy to transport.
Another object of the present invention is to provide a package for glassware which consumes minimum space for ease of storage.
Still another object of the present invention is to provide a glassware package particularly suitable for storing chemical glassware of odd configurations in a minimum of space wherein the package is of lightweight and durable construction to reduce inadvertent breakage of the glassware.
Other objects and fuller understanding of the invention may be had by referring to the following description and claims taken in conjunction with the accompanying drawings in which:
FIG. 1 is a perspective view of a package constructed in accordance with the present invention;
FIG. 2 is a perspective view of the package illustrated in FIG. 1 in an open position;
FIG. 3 is a sectional view taken along line 33 of FIG. 2;
FIG. 4 is another perspective view of the interior of the package illustrated in FIGS. 13;
FIG. 5 is a sectional view taken along line 55 of FIG. 4; and
FIG. 6 is an enlarged sectional view taken along line 6-6 of FIG. 1.
Referring now to the drawings, and especially FIGS. 1, 2 and 6 thereof, a package 10 having an upper and lower portion 11 and 12, respectively, is illustrated therein. Each of the portions has upstanding and outwardly angulated side walls 13, 14, 15, 16; upstanding and outwardly angulated end walls 17, 18, 19, 20; and substantially planar top and bottom walls 21 and 22, respectively. As shown in the drawings, the upper portion 11 is hingedly connected to the lower portion 12 by a hinge 23 which connects the side wall 14 to the side wall 16, each of the portions being adapted to mate and abut in wall to wall engagement so as to define a glass receiving compartment 24 therein.
As the package 10 is preferably made of a lightweight molded plastic such as molded expanded polystyrene, it is a simple matter, when molding the portions to provide indentations 25 in the interior of the walls 21 and 22, which indentations conform to a portion of the outline of glassware items 26 thereby preventing displacement of the items 26 when the package is closed. As may be seen in the drawings, the glassware may comprise such items as flasks 26a, adapters 26b, condensers 26c, funnels 26d, stoppers and/or plugs 26c, tubes 267 and the like. A slot 27 may be provided to receive a thermometer (not shown).
In accordance with the invention, as only a few of the glassware items are particularly large, for example, the 250 and 500 milliliter flasks 26a, and as it is desirable to permit placement of the maximum number of glassware items in the smallest possible space, means are provided to permit the larger items to fit indentations in both the upper and lower portions 11 and 12 while serving the additional function of storage of smaller items. To this end, a removable tray 30 mounts within the glass receiving compartment 24 and permits large glassware items such as the flasks 26a mounted in an indentation in the lower portion to seat in another indentation in the upper portion by providing suitable apertures 31 large enough to permit passage through the tray of large glassware items. In addition, as illustrated in FIGS. 2-4, the removable tray 30 has a portion 32 which permits storage of small glassware items and when in position, in the package, prevents these items from inadvertent movement by the indentations associated therewith in the upper portion 11.
As previously stated, the tray is removable so as to permit easy access to other glassware items stored in the lower portion 12. In order to provide easy removal of the tray 30 from the package upon opening thereof while simultaneously permitting easy storage of the entire package, and in accordance with another feature of .the invention, means are provided on the tray for easy gripping of the tray from the exterior of the package which means are contained within the package and do not project therefrom so as to interfere with storage of the package.
To this end, the tray 30 is provided with handles 33 which, as illustrated in FIGS. 3 and 5, project from each end of the tray and register with slots 34 having outwardly diverging upper and lower edges 34a and 34b, in the end walls of the upper and lower portions 11 and 12, respectively. Although the handles project from the tray, they terminate interiorly of the end walls so as not to project from the package, thus permitting ease of storage of the package. As may be noted in the drawings, providing the slots 34 so that they diverge outwardly, while providing handles 33 which diverge inwardly, permits the user to place his fingers into the V-shaped slot 35 defined therebetween, for ease of lifting the tray 30 from the package 10. In addition, as will become evident hereinafter, this novel feature also permits the entire package, when closed, to be easily carried by the handles.
In accordance with another novel feature of the present invention, the tray 30 may easily be fitted into the interior of the upper portion 11 of the package 10. This feature, as illustrated in FIG. 4, permits full access to the glassware carried on the tray and the glassware carried in the lower portion 12.
For ease of securing the package for carrying and for storage, grooves 40, 41 and 42, 43 are placed in the exterior of the upper and lower portions, respectively, adjacent the corners thereof opposite the hinge 23 to receive therein ties such as rubber bands for holding the upper and lower portions in wall-to-wall engagement. In addition, a pocket 45 is placed in the exterior of the ppper portion 11 to receive therein brochures and the ike.
Thus, the package constructed in accordance with the present invention provides the advantages of permitting a number of odd-shaped glassware items to be situated in less space while permitting ease of storage of large and small glassware :sirnulmneously while preventing inadvertent lateral movement thereof within the package,
thereby reducing the chances of inadvertent breakage of the glassware items with the package. Further, a tray for a package of the present invention is provided which, while permitting easy access by the user is capable of storage in the package so as to expose all of the glassware for use. In addition, the overall design of the package permits easy storing of the package without any projections therefrom so as to cause interference or the like with other items that are being stored on the exterior surrounding the package.
Although the invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be made without departing from the spirit and the scope of the invention as hereinafter claimed.
