l6 claims. (ci. 229-40) This invention relates to improvements in packaging l cartons including cartons desirable for packaging products such `as sliced bacon and the like which is relatively heavy in proportion to the dimensions of the product.

The main objects of this invention are:

First, to provide a carton for packaging products such as food products which is of generally parallelogram shape viewed endwise and at the same time is effectively resistant to load crushing or distorting stresses.

Second, to provide a carton having these advantages formed of a single cut and scored blank of container board which may be of relatively light stock and is strong `and rigid when erected and may be repeatedly handled without distortion.

Objects relating to details and economies of the inven- 'tion Iwill appear from the description to follow. The

invention is deiined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a front perspective view of an erected carton embodying my invention.

Fig. 2 is an end elevational View thereof, portions being broken away to conventionally illustrate sliced bacon or the like.

Fig. 3 is an enlarged fragmentary view in vertical section on Ia line corresponding to line 3-3 of Fig. 2.

Fig. 4 is a fragmentary perspective view illustrating steps in erecting the carton.

Fig. 5 is a plan view of the blank, the scoring thereof being conventionally illustrated.

In the accompanying drawing I have illustrated my invention as embodied in a carton adapted for the packaging of sliced bacon or the like which is conventionally illustrated at 1 in Fig. 2 of the drawing.

The embodiment of my invention illustrated comprises a bottom 2, front wall 3 hingedly connected thereto by the score line 4. The inner rear Wall member 5 is hinged- 1y connected to the rear edge of the bottom by the folding score 6. The cover 7 is hingedly connected to the front wall by the score 8. At its swinging edge the cover is provided with an outer rear 'wall member 9 hingedly connected thereto by the hinging score 10. This outer rear Wall member 9 is provided on its bottom edge with a closure flap 11 which is hingedly connected thereto by the score 12 and is adapted to be folded upon the underside of the bottom as is illustrated in the drawing.

The inner end wall members 13 are of parallelogram shape and are hingedly connected to the ends of the bottom by the score 14. The front wall 3 is provided with end aps 15 hingedly connected thereto by the scores 16 yand connected to the adjacent ends of the inner end wall members by the foldable aps 17 dened by the perforations 18, that is, the perforations result in the folding of the parts 17 on predetermined lines.

At their rear ends the inner end wall members 13 are outer edges to provide tongues 20. These tongues are insertable through the angled slits 21 in an inner rear wall member with the tongues lockingly engaging the portions of the rear wall above the angled portions of the slit, as is illustrated in Fig. 3. 'I'his provides an eifective support for the inner rear wall member and also a support for the inner end wall members as well as providing an effective closed joint between these parts.

The top is provided with outer wall members 22 hingedly connected thereto by the scores 23. These outer wall members are connected to the end flaps 24 which are hingedly connected to the ends of the outer rear wall members by the scores 25 by means of the folding members 26. The outer wall members and the ends flaps 24 are, in effect, continuous, the perforations 27 result in folding on predetermined lines.

The outer end wall members 22 are conformed to provide rear portions of a vertical Width substantially oorresponding to the vertical width ofthe inner side wall members and front portions of substantially reduced vertical width. The rear portions are provided with forwardly projecting tongues 28 on their front edges. The closure flap 11 is provided with anchoring flaps 29 at the ends thereof. These iiaps 29 are foldable upwardly upon the said rear portions of the outer side wall members and `are provided with rearwardly facing tongues 31 interlockingly engageable with the tongues 28 thereof with the upper ends of the anchoring flaps 29 disposed between the inner and outer wall members into supporting engagement with the top. The front edges of these anchoring flaps are exposed for engagement at the outer side Wall members, thereby facilitating the closing and the opening of the carton.

In the embodiment illustrated the top wall is provided with a window 32 of substantial size, the window being provided with a transparent closure, conventionally illustrated at 33. With this arrangement of parts the carton may be partially erected the contents placed therein and -the cover swung to and secured in closed position. The manual manipulations required are easily and quickly performed.

I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate other adaptations or embodiments which I contemplate as it is believed that this disclosure will enable those skilled in the art .to embody or adapt my invention as may be desired.
