6 Claims. (01.- 2'oe-4s) This invention relates to a container for phonograph needles or similar small objects.

It has heretofore been the practice to package phonograph needles either in paper envelopes or in large cardboard backs. Packages of this type do not pack well and the needles are likely to be torn loose. Furthermore the packages are not attractive.

The present package affords a clear view from all sides of the needle, has no projecting portions, may readily be packed for shipment or mailed in an ordinary envelope, and provides an attractive display. At thesame time the needle is sealed against dirt and moisture andcannot be dislodged, lost or stolen without removing the entire package. Furthermore the package provides for the use of a gasket which may be used for ornamentation or advertising purposes.

The invention is illustrated in the drawing in which Fig. 1 is a plan view of the container with a needle within it; Fig; 2 is a side elevation thereof; Fig. 3 is a section taken along the line 3 in Fig. 1; Fig. 4 is a view corresponding to Fig. l of the lower half of, the container; Fig. 5 is a plan view of the gasket; and Fig. 6 isa view of the underside of the. top half of the container.

As shown in theldrawing, the container III is ttom portion II and a cover portion I2, each of which is made from a transparent, thermoplastic, non-frangible material. It is preferred to use a resinous material such as the methyl methacrylate resins, or a styrene composition. The bottom portion ll, while molded integrally, may be considered as comprising a bottom plate l3 provided with an upstanding peripheral flange I4 which provides an abutment l5 at its upper edge, which supports a paper gasket I6. correspondingly, the cover portion I2 may be considered as formed from a cover plate I! provided with a down-turned peripheral flange is, likewise provided with an abutment H3 at its lower edge.

Interlock means are provided on top and bottom. It is preferred to have at least two sets of interlocks. In the form here shown, the bot-' tom portion of the container is provided with a pair of pins and the cover portion with a pair of complementary cavities 2|. The pins are placed upon the studs 22 and the cavities are formed in studs or ears 23. Obviously other forms of interlock means-may be employed and the relative positioning of the male and female members may be reversed or the cover may be provided with one male and one female element and the bottom with complementary interlock portions.

confining means are provided within the container for holding the needle or other elongated small object. In its preferred form this confin ing device consists of an casket 25. In its simplest form the casket is formed in two equal sections, the lower half 25a being integrally formed with the bottom portion of the container, and the upper half 25b being formed integrally withlthe cover of the container. The interior tire container including casket is integrally formed from a transparent.thermoplastic, nonfrangible material. The gasketlli is preferably a fibrous sheet provided with a central opening 21 slightly smaller than the casket, and side slots 28 of a size suflicient to admit the pins 20. The gasket may readily be provided with ornamentation or advertising to accentuate the needle or other material within the casket, and the top or bottom portion thereof may readily be provided with printed matter, giving directions for opening of. the containerand installation and use of the needle.

' The bottom and cover portions of the container may be secured together bythe use of a small amount of solvent in the cavities 2| or upon the pins 20, but it is much more satisfactory to fuse a small portion of the pin afterassembly of the container. This may be accomplished by the insertion of a hot needle through the wall of the container into the pin. This leaves a very small punctured area where the needle has been withdrawn and produces a small area of cloudiness around it which does not detract from the attractiveness of the container.

This method has the further advantage that a package so prepared is practically non-refillable. Once it has been opened the package cannot be again sealed without there being obvious and clear evidence of the tampering. Also, the cover and bottom portions are thin enough so that the act of prying them apart, once sealed, slightly warps them, and the package'cannot even be closed tightly thereafter.

The foregoing detailed description has been given for clearness of understanding only, and no'unnecessary limitations should be understood therefrom.

What I claim as new, Letters Patent, is:

1. A package for elongated small objects com prising a relatively large thin transparent nonand desire to secure by integral upstanding split:

26 of therasket is, only slightly a larger than the needle it is to'contain. The enfrangible bottom portion, a relatively small central cavity therein of substantially the size of the elongated object to be contained therein, a transparent thin non-frangible thermoplastic cover, a central cavity in the cover corresponding to'the central cavity in the bottom portion, and means for positioning cover and bottom portions to bring the corresponding cavities into alignment. v

2. A package as set forth in claim 1, in which an ornamented gasket substantially divides the cover and bottom portions except for the central cavity.

3. A container comprising-a thin flat base vprovided with an integra1 upstanding periphera1 flange, a thin flat cover having a downwardly directed peripheral flange adapted to abut on the upstanding flange oi the base, and an elongated centrally located integral split casket having complementary portions integrally formed from the base and cover, the cover and base portions being of transparent non-frangible thermoplastic mat'erial.

4. A container as set forth in claim 3, in which the base and cover portions ar provided with integral interlock means.

5. A transparent thermoplastic container comprising top and bottom portions, the top and bottom being provided with at least two sets of integral complementary int rlock means, each set of interlock means includi g a male and female member, and the male member of each interlock means being partially fused to the corresponding ijemale member of the interlock means, and there being a small punctured area associated with each set of interlocking means extending to the periphery of the container.

6. A container comprising a thin flat disk base portion provided with an integral upstanding circumferential flange, at least two studs adjacent the flange, a thin flat disk cover poption having a downwardly directed circumferential flange adapted to abut on the upstanding flange of the base and provided with studs complementary to and adapted to abut upon the studs of the base portion, the studs being provided with complementary male and female interlock members, the base'and coverbeing composed substantially entirely of transparent thermoplastic non-frangible material, and an elongated centrally'located integral split casket having complementary portions integrally formed from the base and cover.
