, QUICK-SEALING CONTAINER Filed April 1'7, 1962 2 Sheets-Sheet 2 FIG. 9

INVENTOR FRED CIGANENKO ATTor United States Patent Ofiice 3,176,904 QUICK-SEALING CONTAINER Fred Ciganenho, H54 Meister St, outh Plainiield, NJ. Filed Apr. 17, 1962, Sci. No. 188,105 7 Qlairns. (El. 229-31) The present invention relates to a quick-sealing, boxlike container. More specifically, the invention is concerned with a device for packaging foodstuffs and like small items for display and sale.

Modern merchandising techniques which have evolved as a result of the development of large food markets require that meats, fruits, vegetables and other relatively small items be individually packaged for display and sale in such markets. Such a package must be sturdy, yet attractive, and must be easily assembled and quickly sealed so as to minimize the amount of time required to package the numerous items involved. The container of the invention has been devised with the criteria in mind.

A primary object of the invention is to provide a container which is readily assembled and quickly sealed to form a tight, sturdy package for foodstufis and like small items.

Another object is to provide a container which is attractive and will enhance the appeal of the items displayed therein.

A further object is to provide a sturdy, durable package which will withstand continued handling and is capable of being easily stored both in the market and in the home.

A still further object is to provide a container which employs a cohesive coating to attain quick sealing thereby minimizing the time necessary to form a durable package of neat appearance.

The invention may be described briefly as a quick-sealing, box-like container comprising a tray having a bottom and side walls, each side Wall lying in a plane near the perpendicular to the plane of the bottom, with a cohesive coating upon exterior surfaces of the tray side walls, and a cover, the cover adapted to be placed in a mating position upon the tray, the cover having a top and side walls, each side wall lying in a plane forming an obtuse angle with the plane of the top. Plications join adjacent ends of the cover side walls, the plications providing seals between the adjacent ends during placement of the cover into the mating position and forming fiexures allowing the cover side walls to be moved toward a position nearer the perpendicular to the plane of the top while remaining plane in form after the cover is placed in the mating position. A'cohesive coating is provided upon interior surfaces of the cover side walls for firmly gripping said co hesive coating upon the tray side walls and sealing the container when the cover is in the mating position upon the tray and the cover side walls are moved toward the near perpendicular position.

The novel features of the invention, as well as addition- 211 objects and advantages thereof, will be more fully understood from the following detailed description of an embodiment of the invention illustrated in the drawings in which:

FIGURE 1 is a perspective view of the sections of a container constructed in accordance with the invention;

FIGURE 2 is a plan view looking into the cover of FIGURE 1 in its initial configuration;

FIGURE 3 is a plan view looking into the cover of FIGURE 1 in its final configuration;

FIGURE 4 is a plan view looking into the tray of FIG- URE 1 in its initial configuration;

FIGURE 5 is a plan view looking into the tray of FIG- URE 1 in its final configuration;

FIGURE 6 is a transverse sectional view illustrating, diagrammatically, the container of FIGURE 1 as it is being assembled;

3,1763% Patented Apr. 6, 1965 diagrammatically, another alternative assembled configuration.

Referring first to FIGURE 1, the container is comprised of two sections, a cover 1 and a tray 2, each section being fabricated of paper, cardboard or a like material. The cover has a generally rectangular top 11 and side walls 12 which are integral with the top and folded downwardly at edges 13 so that side walls 12 make an obtuse angle A (see FIGURE 6) with top 11. Adjacent ends of the side walls such as, for example, ends 14 are joined together by folds or plications 15 formed by outwardly folded extensions 16 of the side walls. These plications serve as fiexures which allow each side wall 12 to be moved about an axis in each edge 13 from a position where each side wall lies in a plane forming an obtuse angle with top 11, as shown in FIGURES l, 2 and 6, toward a position where the side wall lies in a plane nearer the perpendicular to top 11, as shown in FIGURES 3 and 7, while maintaining the side walls plane and undistorted. A window 17 may be provided in the top and is formed by providing an opening 17a in top 11 and fixing a sheet of cellulose acetate 17b or alike transparent material to the internal surface 18 of the top to cover. the opening 17a.

The tray 2 has a bottom 21 and side walls 22 which are integral with the bottom and folded upwardly at edges 23 so that side walls 22 make an acute angle B (see FIGURE 6) with bottom 21. Adjacent ends of the side walls such as, for example, ends 24 are joined together by folds or plications 25 formed by inwardly folded extensions 26 of the side walls. These plications serve as fiexures which allow each side wall 22 tobe moved about an axis in each edge 23 from a position Where each side wall lies in a plane forming an acute angle with bottom 21, as shown in FIGURES 1, 4 and 6, to a position where the side wall lies in a plane nearer the perpendicirlar to bottom 21, as shown in FIGURES 5 and '7, while maintaining the side walls plane and undistorted. The dimensions of the cover are so related to the dimensions of the tray that the sections will telescope when assembled as indicated in FIGURES 6 and 7.

Interior surfaces 32 of cover side walls 12 and interior surfaces 35 of plications 15 are coated with a cohesive substance. For the purposes of the instant description, a cohesive substance is defined as one which normally will not adhere to plain paper, cardboard or wood as would an adhesive, but will adhere tenaciously to and firmly grip a similar coating. Suitable cohesive coatings may be made of a latex or rubber base material and are known in the art. 7

Similarly, exterior surfaces 42 of tray side walls 22 are coated with a cohesive substance. It is noted that the plications 25 are not coated.

In assembling a container, the contents Ell which are to be packaged are'first placed in the tray asshown diagrammatically in FIGURE 6. Then the cover is placed over the tray with its contents and pressed downwardly as indicated. Initially, the angle of the tray side walls 22 relative to bottom 21 and the angle of the cover side walls 12 relative to top 11 will ensure that these elements do not contact one another prematurely, thereby causing the cohesive coatings to stick to one another and preventing the proper location of cover 1 upon tray 2. As cover 1 is pressed downwardly, the contents are compressed slightly and tend to force tray side walls 22 outwardly toward a position nearer the perpendicular to bottom 21.

4 3 When cover 1 is in proper mating position upon tray 2, cover side walls 12 may be pushed against tray side walls 22 so vrthat interior surfaces 32 of the cover side walls will mate with exterior surfaces 42 of the tray side walls. The cohesive coatings on each section are thus'brought together so that the side walls firmly grip one another and seal the container (FIGURE 7). Because of the wide variety of shapes and sizes of items to be packaged and the desire to maintain a minimum number of sizes of container sections, the depth available in a container of the invention may be varied merely by sealing the sections together at any desired vertical telescoping position as long as enough area is provided at the mating surfaces to effect a proper seal. Thus, a proper mating position for the cover may be the. one shown in FIGURE 8 where top 1 1 is displaced vertically from tray 2 to accommodate contents 50a having a greater height than the contents 50 in FIGURE 7 where the top 11 is in proper mating position when seated upon tray side walls 22. Where use of the container as illustrated in FIGURE 8 is contemplated, the cohesive coatings need not cover the entire area of interior surfaces 32 and exterior surfaces 42, but only those areas which will come into sealing contact. Extensions 16 which form plications are brought together by the movement of the cover side walls to form ears 36. These ears serve a dual function: First, they tightly seal the corners of the package to prevent leakage at these corners and second, they provide positive means for bolding the cover side Walls in sealing position and reinforce the seal formed by the cohesive coatings on the mating surfaces of the side walls. Piications likewise serve to prevent leakage at the corners of the 'tray. 7 Thus, even when top 11 is not seated upon tray 2, as illustrated in 7 FIGURE 8, the corners of the container will still be sealed. It is noted that the plieations in both the cover and the tray serve to maintain all of the side walls in an undistorted planar configuration as pointed out'hereinbefore. Such a configuration ensures a proper seal throughout the perimeter of the container by maintaining the mating surfaces flat.

When the cover is provided with a window 17, it is preferable to employ a shallow rib 51 formed in top 11 surrounding the opening 17a. The rib allows a slightamount of vertical play in top 11 relative to cover side walls 12 thus tending to relieve some of the strain placed upon sheet 17b during the sealing operation (see FIG- URES 6 and 7).

In certain applications, it has been found that a seal of even greater strength may be elfected by allowing the tray side walls to move slightly beyond the perpendicular position shown in FIGURE 7 so as to form an obtuse angle with the bottom in the final sealed'configuration as shown in FIGURE 9. The cover is then fabricated with a top 11 having a'slightly larger area than bottom 21 so that the cover side walls may be moved slightly beyond the perpendicular to a position forming. an acute angle C with the top in the final, sealed configuration and mating with the tray side walls. Again, the cover pl-ications,

. 1 sealed to form ears 36, would tend to hold the cover side walls in'sealing position while ensuring that the corners are tightly sealed. I

Where the contents 50 are not readily compressible or will riot entirely fill the tray, it may be preferable to employ a tray having side walls fixed in a position at or near the perpendicular to the bottom. In such a case, it has been found that the'obtuse angle of the cover side walls will be sufiicient to preclude premature contact of the cohesive coatings on the cover and 'on the tray, though the margin of safety is not as great as when the trayside walls are movable as well as the cover side walls.

Since the cohesive coatings will not stick to plain paper;

4 be placed in nested arrangement without these like sections sticking to one another.

It is apparent from the above description that a con tainer has been devised which is sturdy and durable enough to withstand the continuous handling to which packaged items are generally subjected in large markets .while still remaining tightly sealed, and maintaining a Modifications may be made in certain details of design 1 and construction without departing from the true spirit cardboard or other materials from which the cover and a tray may be fabricated, like sections may be stored in their own individual stacks prior to use and may even and scope of the invention as set forth in the appended claims.
