DISPLAY PACKAGE HAVING SLIDING TRAY Filed Feb. 17, 1966 2 Sheets-Sheet 2 I 4 |NVENTOR EUGENE H. RIESTENBERG Attorneys United States Patent Ofifice 3,326,371 Patented June 20, 1967 3,326,371 DISPLAY PACKAGE HAVING SLIDING TRAY Eugene H. Riestcnberg, Cincinnati, Ohio, assignor to The Central Carton Company, Cincinnati, Ohio, a corporation of Ohio Filed Feb. 17, 1966, Ser. No. 528,278 1 Claim. (Cl. 206-78) This invention relates to packages for articles. More particularly, this invention relates to a display package having a transparent tray for holding articles.

A convenient device for displaying articles for sale is the so-called blister pack or package in which articles are held in a transparent tray. An object of this invention is to provide such a package in which the transparent tray is held in a paperboard backing card and in which the tray can be slid between a closed position and an open position at which access is provided to the contents of the tray.

A further object of this invention is to provide a package of this type in which the transparent tray is held in locked position in the card when the tray is not open.

A further object of this invention is to provide a package of this type in which a single thickness of paperboard card holds the tray.

The above and other objects and features of the invention will be apparent to those skilled in the art to which this invention pertains from the following detailed description, and the drawings, in which:

FIG. 1 is a view in front elevation of a package constructed in accordance with an embodiment of this invention;

FIG. 2 is a view in section taken on the line 22 in FIG. 1;

FIG. 3 is a view in section taken on the line 33 in FIG. 1;

FIG. 4 is a view in side elevation of the package with the card being shown in tray released position, the tray being shown in open position in dot-dash lines;

FIG. 5 is a plan view of the card portion of the package;

FIG. 6 is a view in side elevation of the blank with the blank being shown in tray-released position, one tab being partly broken away to reveal details of construction; and

FIG. 7 is a view in section on an enlarged scale taken on the line 77 in FIG. 5.

In the following detailed description, and the drawings, like reference characters indicate like parts.

In FIGS. 1 to 4, inclusive, is shown a package which includes a transparent tray 10 and a backing card 12. The tray 10, as shown in FIGS. 2 and 3, is of dish shape having an outer wall 13, side walls 14 and 16 (FIG. 3) and end walls 17 and 18 (FIG. 2). A flange 19 extends outwardly from free edges of the wall. The outer edge of the flange 19 is substantially rectangular in shape, corners being rounded to eliminate sharp points.

Details of construction of the backing card 12 are shown in FIG. 5. The card is formed of paperboard or the like and includes a main panel 21 and an upper panel 22. In the upper panel 22 is formed a slot 23 by means of which the package can be supported on an appropriate support (not shown), The panels 21 and 22 are separated by aligned score line portions 24 and 26 which form a line of weakening or hinge line between the panels. Between the score line portions 24 and 26 is formed a U-shaped line of cut 27 defining a stop tab 28. The main portion 21 is provided with three outwardly facing U-shaped lines of cut 29, 31, and 32, which are arranged in rectangular fashion with relation to the stop tab 28, and form tabs 33, 34-, and 36. The tabs 33, 34 and 36 can be bent away from the plane of the main panel 21 as the tabs are formed as shown in FIG. 6 and can engage portions of the flange 19 of the tray 10 as shown in FIGS. 1 and 4 cooperating with the stop tab 28 to hold the tray in place on the card. When desired, the upper panel 22 can be swung back to the position shown in FIGS. 6 and 4 to swing the stop tab 28 out of engagement with the flange 19 of the tray as shown in FIG. 4, so that the tray can be slid from the full line position of FIG. 4 to the dot-dash line position at which articles in the tray are exposed and removable. The tabs 33 and 36 are parallel and form tracks along which the tray slides. When the tray is in closed position, the stop tab 28 and the tab 34 engage opposite edges of the flange 19 of the tray to hold the tray in closed position.

The package construction illustrated in the drawings and described above is subject to structural modification without departing from the spirit and scope of the appended claim.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

A package which comprises a tray including a cupshaped body and an outwardly extending flange surrounding the body and a card supporting the tray, said card including a main panel and an upper panel, said panels being separated by a pair of aligned hinge lines, there being a U-shaped line of cut connecting the hinge lines and defining a stop tab, there being a pair of U-shaped lines cut in the main panel defining inwardly directed elongated parallel tabs, the tabs being engageable with the flange of the tray to hold the tray in engagement with the main panel, a third tab in the main panel arranged in rectangular fashion with regard to the stop tab and the parallel tabs, said third tab of the main panel engaging the flange when the stop tab engages the flange, the upper panel and the stop tab being swingable together to release the flange, the tray being advanceable to an open position in which contents of the tray are accessible with the parallel tabs holding the tray and card in assembled relation.
