PATENTEDuuv 23 IQYI JACK E. PREGONT l N VENTOR.

Attorney BACKGROUND OF THE INVENTION l. Field of the Invention The present invention relates to containers for packaging and displaying small articles and more particularly to such containers which are reclosable and resistant to surreptitious pilferage.

2. Description of the Prior Art In recent years, many small articles have been packaged for sale in expendable containers of the so-called blister or bubble type comprising a transparent boxlike member sealed to a flat card member. Since the card member must be torn away from the bubble or blister to open the container, a very significant advantage of this type of packaging is that a purchaser can readily determine whether the container he wishes to buy has been previously opened. In 'many cases, though, the purchaser would like to be able to reuse the same container to store the purchased article or articles, which is not conveniently possible if the container must be partially destroyed to open it. Accordingly, it is also well known to provide containers of the same general type in which the transparent boxlike member includes bent over edge lips which engage the flat card member so that the latter can be slid to open and closed'positions after a sealing member has been torn or broken. However, the latter type of container inherently complicates the packaging process of requiring that the card member and the boxlike member be slid into mating engagement with each other rather than simply being placed'in facing contact and sealed together. Furthermore, the initial sealing of such a container is customarily accomplished by means of a separate piece of pressure sensitive tape or the like, which often can be surreptitiously peeled back and then replaced after the contents of the container have been handled or pilfered.

SUMMARY OF THE INVENTION In accordance with the present invention, a pilferproof reclosable container comprises aboxlike body member which is preferably made of sheet plastic material by pressure-forming or vacuum-forming techniques. A' peripheral lip of the boxlike member is provided with a shallow recess adapted to receive the edges of a transparent flat rectangular lid member which covers the contents located in the box member. After the contents have been placed within the boxlike member and the lid member has been laid in place, a flat card member is laid atop the boxlike member and is sealed to the peripheral lip of the latter, preferably by a heat sealing operation. The card member is provided with a central window and overlaps the edges of the lid member to hold the latter in place. A perforated line or the like defines a portion of the card member which is adapted to be torn away so that the corresponding end of the lid can be grasped and bent through the resulting opening in the card to enable the lid to be slid open. When the lid is returned to its initial position, its inherent resiliency retains it within the shallow recess of the boxlike member until it is again grasped and bent upwardly through the lid opening.

Various means for practicing the invention and other advantages and novel features thereof will be apparent from the following detailed description of an illustrative preferred embodiment of the invention, reference being made to the accompanying drawings in which like reference numerals denote like elements.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is an exploded perspective view of a-container ac cording to a preferred embodiment of the present invention;

FIG. 2 is a plan view of anassembled container comprising the elements depicted in FIG. 1, with portions of the card member and lid shown broken away to illustrate internal details;

FIG. 3 is a cross section end elevational view of the container taken along like 3-3 of FIG. 2;

FIG. 4 is a cross section side elevational view of the container taken along line 4-4 of FIG. 2;

FIG. 5 is a cross section side elevational view of the container corresponding generally to an enlarged portion of FIG. 4, and

FIG. 6 is a perspective view of the assembled container showing the manner in which the lid thereof is opened and closed.

DESCRIPTION OF THE ILLUSTRATIVE PREFERRED EMBODIMENT As best shown in FIG. 1 of the accompanying drawings, the illustrative preferred embodiment of the container according to the present invention is of very simple construction, comprising a body member 11, a lid member 12 and a card member 13.The body member is preferably formed from relatively rigid sheet plastic material by a pressure or vacuum fonning process and includes a flat rectangular peripheral lip 14 and a central cavity or box portion 15 adapted to receive the contents of the container represented by a diskshaped object 16. A shallow rectangular recess I7 in lip 14 surrounds the cavity or box portion of the body member and is adapted to receive the slightly smaller rectangular lid member 12, which is preferably made of thin resilient transparent sheet plastic material. At one end of the central cavity 15, the body member also includes a depression 18, which interrupts and extends beyond the adjacent portion of recess 17 to facilitate opening and closing the lid member, as explained in greater detail below. The card member 13, which is preferably made of flat cardboard stock, is of the same external dimensions as the peripheral lip of the body member and is provided with a central rectangular window 19 somewhat smaller than lid member 12.

To assemble the illustrative container, the contents thereof are placed in the cavity or box portion of the body member while the latter is located in a horizontal position and lid 12 is positioned horizontally in recess 17. The card member is then laid atop the body member and is sealed to the peripheral lip thereof, preferably by a heat sealing process employing a heatsensitive adhesive coated onto the lower surface of the card member. Since the contents of the container and the lid and card member thereof are simply laid in place while the body member remains in the horizontal position shown in FIG. 1, it should be apparent that the subject container is admirably suited to being assembled by means of a relatively simple and inexpensive automated packaging machine comprising a conveyor provided with a plurality of nests which carry individual container body members to successive loading stations at which the other container components are subsequently placed in position and then to a sealing station at which the card member is sealed automatically to the body member.

As shown at numeral 20, the card member 13 is provided with a perforated or scored separation line, which intersects the lateral edges of window 19 and defines portion 21 of the card that can be torn away to provide an opening 22, as shown in FIG. 6. Before the portion 21 of the card is removed, the rectangular central card window 19 is aligned with cavity 15 of the body member and overlaps all four edges of the lid loosely received in recess 17, thereby maintaining the lid in the position shown in FIGS. 2 throughS. The portion of the card defined by the separation line is wider than the lid and overlaps above the end thereof adjacent depression 18 in body member recess 17. Accordingly, after the card portion 21 has been removed, the customer can grasp the corresponding end of the lid and bend that end of the card upwardly through opening 22, whereupon the lid can be slid along recess 17 to an open position as illustrated in FIG. 6. Depression 18 in the body member is adapted to facilitate this operation by permitting the customer to insert the tip of his index finger below the end of the lid member as he grips the upper face of that end of the lid with his thumb. To reclose the container, the lid member is simply slid back to its initial position and released,

thereby allowing its inherent resilience to restore it to its former generally flat condition within recess 17 so that it cannot slide open until it is again grasped and bent upwardly through opening 22.

The invention has been described in detail with particular reference to an illustrative preferred embodiment thereof but it will be apparent that variations and modifications can be effected within the spirit and scope of the invention as described hereinbefore and as defined in the appended claims.
