Abstract
A carton formed of foldable paperboard or corresponding material, folded from a blank in which the four sides (10-13) of the carton are interconnected in sequence. The bottom of the carton is composed of at least two bottom flaps (19, 20) projecting from opposing sides. One of the sides (10) which is provided with a bottom flap comprises a lid (10b) nearby said flap, enabling discharge of goods loaded in the carton. The nearby bottom flap (19) is provided with an extension part (25) which can be folded down to form a distance element, the end edge of which abuts the inside of the other bottom flap (20).
Description
- The invention relates to a carton formed of foldable paperboard or corresponding material, folded from a blank in which the four sides the carton are interconnected in sequence, and in which the bottom of the carton is composed of at least two bottom flaps projecting from opposing sides.
- It is common to use collapsible returnable plywood boxes for storing and transport of for example potatoes from producers to the market. The box is provided with a comparatively small openable lid in one of the sides, nearby the bottom of the box. A drawback with these return boxes is that they must be thoroughly cleaned between times of use, so that no parasites, mould or other hazardous pollution can be transmitted from one load of potatoes to another. Naturally, it is possible to use disposable carton boxes for this purpose. However, it has proven to be difficult to accomplish a carton box which can be opened and emptied via a lid nearby the bottom. It is inappropriate to open the carton via an upper lid, because potatoes should not be subjected to light.
- For a returnable plywood box it is justified to provide the box with a comparably expensive lid device. However, a disposable box must be cheap and simple to produce. Also, the lid must be easy to open, without risking the lid opening at an inconvenient moment, i.e. in loaded condition during transport and handling.
- One object of the present invention is to provide a disposable carton box which can be formed from a one-piece blank and provides a solution for the above described problems.
- According to the invention, one of the sides which is provided with a bottom flap comprises a lid nearby said flap, enabling discharge of goods loaded in the carton, and that the nearby bottom flap is provided with an extension part which can be folded down to form a distance element, the end edge of which abuts the inside of the other bottom flap.
- Preferable embodiments of the invention are described in the accompanying subclaims.
- One embodiment of the invention will now be described in more detail with reference to the accompanying drawing, in which
- Fig. 1 is a plane view showing a carton blank,
- Fig. 2 and 3 shows the mounted carton in perspective from two different directions.
- The
reference numbers said walls 10 is provided with alid 10b which is formed by twoperforations 10a which will be described in more detail below. The four side walls are interconnected in sequence, so that aflap 14 belonging to theside wall 10 can be fastened to theside wall 13 forming a tubular carton blank. - Each side wall at the upper end of this tubular carton blank is provided
top flap - Both the
long sides bottom flaps short sides bottom flaps slit openings portions pallet element 23, for elevating the carton above a surface allowing insertion of a fork lift. - The
bottom flap 19 is provided with aslit 24 adjacent thelid 10b and anextension portion 25. Theslit 24 is slightly longer than the size of thelid 10b. Thebottom flap 20 is provided with atongue 26 with broadening flap means 26a and a finger opening 26b. The total width of thelid 26 and the flap means 26a corresponds to the size of theslit 24. - All of the above mentioned side flaps, top flaps and bottom flaps are conventionally connected along
fold lines 27 which facilitate the erection of the carton blank into a box. - Erection is performed in the following way:
First the tubular carton blank is folded up from a flat position to an erected position, then thebottom flap 19 is folded into the box with the extension portion folded down, i.e. with free edge of the extension portion pointing towards the bottom opening of the box. Then thebottom flap 20 is folded up and thetongue 26 is inserted into theslit 24. Now thepallet element 23 can be mounted by means of thebottom flaps tongue 26 is located inside thelid 10b and strengthens this portion because theflap portions 26a extends outside the edge of the lid. Accordingly, there is no risk of the carton contents pressing thelid 10b open. - Discharge of the carton is performed in the following way:
First theseal 10a is broken by folding up thelid 10b. Then a finger is inserted into thehole 26b, by means of which thetongue 26 can be folded out through the lid opening by simultaneous folding back of theflaps 26b. The contents of the carton can now be discharged in a desired rate via the lid opening. If the contents of the carton is potatoes, it may be necessary to assist a little with the hand to push them through the opening. Then thelid 10b will spring back essentially preventing light from entering via the lid opening. Discharge of the carton is facilitated because the edge of theextension portion 25 abuts the inside of thebottom flap 20, so that theflap 19 itself forms an inclined plane at the bottom of the carton said plane being inclined in the direction of the lid opening. - Even if a specific embodiment of the invention is shown in the drawings, it is obvious that further alternatives and modifications are possible within the scope of the patent claims. Naturally, the carton can be shaped differently. For example, the
pallet element 23 does not form a part of the. The carton can also be used for other goods than potatoes.
