TRAY-FORMING CARTON This invention relates to paperboard cartons which may be converted by a simple manipulation from a closed condition to an open, tray-forming condition.
In the paperboard field, there exists a need for a carton which readily may be converted from a closed, sealed condition to an open tray condition. For example,'in the merchandising of bakery and other food products, it would be desirable to load shallow paperboard containers with the food product, close the containers, store them for whatever period is .necessary, transport them to the location in which the products are to be dispensed and then, in a simple operation, remove the top. This displays the products to be merchandised in an open traylike container from which they readily may be dispensed.
It is the general object of the present invention to provide a paperboard container which may readily be converted from its sealed carton form to an open tray form and which in addition is characterized by the following advantageous features: 1. The manipulation by means of which the conversion is effectuated is carried out easily and rapidly. 2. The carton is easily manufactured, using conventional carton-making apparatus. 3. The carton is strong and protects the contents from damage during transportation and storage. 4. The carton may be manufactured in a variety of sizes and shapes as required to suit various products. 5. Although the carton is sealed securely, its contents are not damaged by the manipulation by means of which it is opened and converted to a tray.
The manner in which the foregoing and other objects of this invention are accomplished will be apparent from the accompanying specification and claims considered together with the drawings, wherein:
FIGS. 1 and 2 are views in perspective of the herein described tray-forming carton illustrated, respectively, in its closed and opened conditions.
The carton of my invention may be made of any suitable container material. Preferably it is made of a single sheet of corrugated container board, suitably cut and folded.
It includes a bottom, indicated generally at 10, and a top indicated generally at 12.
Bottom includes a bottom piece 14 to which are attached flaps which may be folded appropriately to form end walls 16, 18, and sidewalls 20, 22. Sidewalls 20, 22 are provided with minor flaps 24, 25, respectively which may be folded inwardly toward each other and secured to the end flaps by suitable means such as staples or glue.
The bottom thus comprised may be of any suitable dimensions, but is generally rectangular in design and shallow in depth since it is the portion which forms the display and dispensing tray during use of the carton.
substantially parallel to the fold line. The tear line is so constituted that by an easy manipulation, top 12 may be removed entirely from bottom 10.
Further to increase the stability of the carton and to afford increased protection to its contents, there may be provided end flaps 30, 32 folded downwardly from top piece 26 and lapping end pieces 16, 18 of bottom 10. End flaps 30, 32 are free in that they are not glued nor stapled to other elements of the carton. This makes it easy to raise and lower the lid.
In the FIG. 1 closed condition of the carton, the outer end of top piece 26 meets and lies closely adjacent the upper edge of bottom side piece 20. Releasable securing means are then provided for releasably securing together 'the two meeting edges thereby closing the carton.
Although various types of mechanical fasteners may be employed for this purpose, it is preferred to employ a strip of adhesive tape 34. If the adhesive tape is of the tear-tape variety, i.e., provided with a central string, a strong, semipermanent closure IS provided which may be easily unfastened at the time of use.
The box thus is a full overlap style box having all of the attendant manufacturing economies. The box may be shipped flat in a knocked down condition with the tear-tape manufacturer's joint already applied. The customer thus is able to use the box on available packaging machinery which automatically sets it up, fills it, and seals the end flaps.
When it is desired to gain access to the contents, tape 34 is severed or removed and top 12 hinged open. If the carton is to be reclosed, the top is retained in its connected condition. However, if it is desired to convert the carton toa tray, the top may be torn off along perforated tear line 28. This converts bottom 10 to a tray in which the merchandise may be displayed to advantage and from which it may be dispensed readily.
Having thus described my invention in preferred embodiments, I claim:
1. A tray-forming carton made from a folded sheet of stiff, foldable paperboard, the carton comprising:
a. a bottom including integral side and end walls of uniform height,
b. a top comprising an integral section of the sheet hinged at one end to the top edge of one of the bottom walls through a fold line,
c. a perforated tear line across the top substantially parallel to the fold line,
(I. the opposite end of the top-forming sheet section meeting the upper edge of the bottom wall opposite the wall to which the sheet section is hinged, and
e. releasable securing means releasably securing the meeting top-forming sheet section end and upper edge of the bottom wall.
2. The carton of claim 1 wherein the securing means comprises adhesive tape.
3. The carton of claim 2 wherein the adhesive tape comprises string-operated tear tape.
4. The carton of claim 1 including a pair of end flaps folded downwardly from opposite ends of the top and lapping the corresponding end walls of the bottom.
Claims (4)
1. A tray-forming carton made from a folded sheet of stiff, foldable paperboard, the carton comprising: a. a bottom including integral side and end walls of uniform height, b. a top comprising an integral section of the sheet hinged at one end to the top edge of one of the bottom walls through a fold line, c. a perforated tear line across the top substantially parallel to the fold line, d. the opposite end of the top-forming sheet section meeting the upper edge of the bottom wall opposite the wall to which the sheet section is hinged, and e. releasable securing means releasably securing the meeting top-forming sheet section end and upper edge of the bottom wall.
2. The carton of claim 1 wherein the securing means comprises adhesive tape.
3. The carton of claim 2 wherein the adhesive tape comprises string-operated tear tape.
4. The carton of claim 1 including a pair of end flaps folded downwardly from opposite ends of the top and lapping the corresponding end walls of the bottom.
