sition during transmission to the user, .and if desired for display purposes, although permitting ready removal of the teeth from the supporting card when desired.

In the copending application of SimonMyerson for Letters Patent Serial No. 313,077, led January 9, 1940, there is disclosed a novel and very desirable device designed to take the place of the usual flat card and having provision for displaying teeth in such a Way as much more closely to simulate the arrangement of natural teeth in the mouth than does the usual card. The improved device of said application comprises a' holder curved to simulate the curvature of the human gum-ridge and includes a gum-simulating part, and mea-ns operative removably' to hold 'a row of teeth, each tooth having its gingival end l "disposed within a cavity or groove containing `retaining wax, the gum-simulating portion of 'the holder partially surrounding the necks of the several teeth. For shipping and display purposes this holder is preferably secured to a stiff supporting base somewhat resembling the usual card on which teeth are ordinarily directly mounted.

While the improved device of the aforesaid application is highly desirable, the curved holder with its complement of teeth projects a substantial distance from the flat support or base on which it is mounted and is thus subject to injury in handling and shipment, unless a substantial degree of care be exercised.

Moreover, and this is equally true with respect to any form of tooth card or holder, whether flat or curved, the teeth mounted on this holder are exposed to the air and to handling and thus subject to contamination from dust, dirt and bacteria.

Furthermore, even though a black or dark colored base be employed for supporting the holder, the lighting effect to which the teeth are exposed is quite diilerent from that which obtains when teeth are actually arranged in the mouth, since, in the latter case, the teeth are viewed against the dark background of the conned oral cavity.

The present invention has for'an object the provision of means operative to protect teeth mounted on a shipping and display card `(whether directly on the card or in a holder carried by the card) both from mechanical injury and from contamination by dirt, dust, etc.

A further object of the invention is to provide a container for teeth mounted upon a holder such, for example, as that disclosed in the aforesaid application, so devised that teeth arranged therein are viewed under lighting eiects somewhat similar to those existent ywhen the teeth are actually in the mouth.

A further object of the invention-is to provide a protective receptacle of simple form which may be employed merely for shipping teeth, together with a. shield device applicable to the receptacle when the teeth are to be displayed or viewed, and which assists in securing the desired lighting effect.

A further object of the invention is to provide a container of attractive appearance which is suiciently rugged to aord the desired protection without being unduly heavy; which is simple, easy and cheap to construct; and which is externally smooth and sanitary.

Other and further objects and advantages ,of the invention will be pointed out hereinafter in the following vmore detailed description and by reference to the accompanying drawing in l which- Fig. 1 is a plan view of the receptacle or container having therein a holder carrying a row of teeth, a portion of the top of the receptacle being broken away, with parts in horizontal section;

Fig. 9 is a plan view .of the shield shown Aas separated from the receptacle.

Referring to the drawing, the letter B (Figs. 2, 4, 5 and 6) designates the base of the receptacle, such base including a substantially horizontal platform portion I (Fig. 5), having the vertical side walls 2 and the substantially flat upper surface 3, the base also comprising the downwardly directed marginal supporting flange 4. In the upper surface of the platform there is provided an elongate recess, the floor 5 of which preferably slopes downwardly and forwardly. The platform has an elongate opening 6 (Fig. 6) in the forward part of the floor of the recess, and an aperture or socket 1, the purpose of which will be described hereinafter. The base B is here illustrated as of' substantially rectangular contour and is provided with a marginal rabbet or recessl 8, the vertical surface 2 of the platform constituting the inner wall of this recess or rabbet.

The platform I is designed to constitute a support for a tooth holder 9. This tooth holder may be an ordinary tooth card, but is here illustrated as of the kind moreful'ly disclosed in the aforesaid `copending application for Letters Patent. As shownu inv Figs. 7 and 8, this holder 9 consists of an integral moulded mass of material, for example hard rubber or a synthetic resin, shaped to provide the rear part IB and the forward or apron portion I I, said portions diverging downwardly from the upper part I2. The forward exposed surface I3 of the apron I IL is colored and contoured to simulate the human gum, while the space between the front and rear parts II and I0 is filled with a body III of wax which embraces and removably holds the gingival portions I5 of the teeth I8. From the rear part I0 projects an integral boss or lug I1 which may be furnished with an aperture I8 for engagement by a securing pin or the like.

This holder is curved or arched in order to simulate the curvature of the human gum-ridge, and when mounted upon the platform I of the base B its ends and 2I (Fig.` 7) are disposed within the recess 5 in the platform 3 with the lugv I'I (Fig. 5) projecting downwardly through the aperture 1, the lug being engaged by suitable retaining means, such as a pin I9. As thus arranged, the holder arches upwardly, as shown in Fig. '7, that is to say it projects substantially above the plane of the platform I.

The improved receptacle o-f the present invention also comprises the housing H (Figs. 1, 2 and 9). This housing may be made of a rigid transparent material, such as glass, but it is preferred to makeit of a somewhat flexible although stiff, non-shattering and shape-retaining transparent material, for example Celluloid or one of the transparent synthetic resins. Desirably, the entire housing is transparent, but if desired, only the top may be transparent. Preferably the Walls of this housing are quite thin to reduce its weight, and the dimensions of the housing are such` as. to provide withinit a chamber K (Fig. 5) of Sunicient dimensions to accommodate the arched toothV holder when the latter is mounted upon the base. This housing, as` illustrated (Figs. 1 and 2), comprises the left and right end walls 22 and 23, the rear wall 2tv and the forward wall 25 (said walls being substantially vertical) and the top wall 26. Preferably the housing consists of an integral piece of material properly moulded to shape, the top 26 being slightly convex upwardly and merging with the vertical walls at smoothly rounded corners. The lower edges of the vertical walls are preferably turned outwardly to form the finish flange 21. The dimensions of this housing are such that its lower edge portion may be seated within the rabbet 8 of the base, with the inner surfaces of its vertical walls snugly and frictionally engaging the vertical surfaces 2 of the base so as thereby normally to retain the housing in assembled relation with the base, thus providing the substantially air-tight chamber K for the accommodation of the holder 9 with its complement of teeth. The housing thus provides substantial protection for the teeth against mechanical injury and contamination from dust and dirt. Since the housing is transparent, the teeth are fully exposed to view without requiring that the housing be removed from the base, but when it is desired t'o remove the holder from the base the housing may readily be removed from the base by pulling the housing and base apart.

The elongate slot 6 in the platform I of the base is so arranged as to underlie the row of teeth I6 so that if the base with the holder mounted thereon be held against a source of light, the light will shine through the slot 6 and thus permit the teeth to be viewed against the light without removing them from the holder.

The receptacle as thus described, comprising only the base and the housing, isy highly useful not only for shipping teeth while keeping them well. protected, but also for display purposes. However, in order to exhibit the teeth in a way closely approximating the appearance of teeth within the human mouth, it is preferred to provide the receptacle with a third element, that is to say, the shield or cap C (Figs. 3, 5. and 9).. This cap may form a permanent part of the holder if desired,` although it is preferably removable. and

may constitute merely an accessory which will be supplied to the dentist or dental laboratory for application when desired to the shipping receptacle comprising only the base and housing.

This. cap C may be made of the same material as, the` housing H if desired, that is to say, a tough, transparent, organic material such as Celluloid or synthetic resin, and comprisesv the top 2,8 and the side walls 29, the latter terminating at their lower edges in a finish flange or bead 30. As. here illustrated the side walls 29 are of less. depth than the vertical walls of the housing, but arey of sufficient depth to provide a secure frictional engagement between the cap and the housing. However, the side walls 29 of the cap may be of substantially the same depth as the vertical walls of the housing if desired. In any case, the dimensions of the cap are such that it fits over the housing with a fairly snug fit, although permitting it to be slipped off at will.

The cap is shown as provided with an elongate Window 3I in its top 28, such window beingl so arranged as to overlie the row of teeth I6 mounted on the holder 9 within the chamber K. Except for this window or aperture 3l, the top 28, at least, of the cap is substantially opaque, being provided as here illustrated with an opaque coating 32 of any suitable character, for example sheetv material or a layer of paint or enamel. Preferably the aperture or window 3I has a distinctive border or margin 33 which is preferably colored red so that, the aperture 3| may have some slight semblance to the human mouth. Likewise, the remainder of the coating 32 may be pink or flesh color, and if desired, a. set of caps mayv be provided, each tinted to simulate. a different complexion, so that in matching teeth for a given patient, the dentist may select a cap correspondingA to the. color of the patients skin. While the opacity of the top of the cap is` here shown as resulting from the application of a surface coating or layer, it is to be understoodthat the top 28 of the cap itself may be inherently opaque, and it is further contemplated that the entire cap, except for the window 3l, may be made of opaque material. It is also contemplated that instead of a free opening the window 3| may consist of a transparent area of the cap material. When the cap C is applied to the top of the housing H, its opaque areas cut olf exterior light from the chamber K to such an extent that the chamber is considerably darkened, and if the surface 3 of the platform l be of a dark color, for example black, this darkening of the chamber by the employment of the cap C' causes the teeth, when viewed through the window 3 l, to approximate very closely in appearance the appearance of teeth in the human mouth,-the colored margin 33 bordering the opening 3| contributing to this appearance. By extending the opaque area of the cap downwardly along the sides of the cap, the darkening of the chamber K may be increased if desired, and if, as above suggested, the side walls of the cap extend down to the base, and if these side walls be opaque throughout, the chamber K may be made completely dark except for the light entering through the Window 3|.

This receptacle thus provides substantial protection for the arched holder during transit from the tooth manufacturer to the dental laboratory or dentist; it furnishes protection for the teeth while on the dentists shelves awaiting use, although permitting ready inspection without exposing them to the air, and when the teeth are the teeth would appear if actually in the mouth.
