Benefits of technology

[0007]A paperboard carton is provided having a top, a bottom, two side panels and two end walls. Perforations formed in the carton are provided to allow a consumer or other user to form a dispenser opening in the top by removing the material of the carton bounded by the perforations. The material used to form the paperboard carton can be any standard paperboard material such as corrugated paperboard that is typically used for packaging or shipping containers. This material provides enough rigidity to the carton to allow it to maintain its shape and retain the product therein. In accordance with this invention, the end walls are modified to provide improved stacking strength for the carton.

Problems solved by technology

However, many of these cartons tend to be large and are designed to hold large numbers of products.
Such cartons are suitable for “warehouse” type operations but are difficult for the consumer to store and use when the consumer needs smaller quantities for typical household activities.
Unfortunately, such stacking can result in damage to the carton causing the consumer to assume that the individual products packaged within the carton are damaged as well.
This is bad for the retailer because such perceived damaged goods are more difficult to sell and thus can result in lower profits.
For example, some of these cartons are in fact difficult to open.
In addition, some of the cartons having such dispensing openings can have compromised structural integrity because of such openings.

second embodiment

[0029]As shown in FIGS. 3 through 5, the easy opening feature of this invention includes a two part opening. This two part opening includes a tear strip 380 and an opening flap 385. Tear strip 380 is a standard feature of paperboard cartons and is used to provide the consumer with a mechanism to easily open carton 100′. As seen in FIG. 3, tear strip 380 extends along a generally middle or middle right portion of top panel 50. Opening flap 385 is adjacent to tear strip 380 along a middle left portion of top panel 50. The exact location of opening flap 385 and tear strip 380 is not critical. All that is necessary is that opening flap 385 and tear strip 380 are conveniently located along a portion of top panel 50 to provide easy access by the consumer to the contents of the carton. Opening flap 385 is bounded at its right side by the left side of tear strip 380, along its top by perforation line 390, along its bottom by perforation line 391 and along its left side by a portion of fourt...

third embodiment

[0030]As shown in FIGS. 6 through 8, the easy opening feature of this invention includes a single opening door 401, which is generally located in the middle or middle left portion of top panel 50. The exact location of opening door 401 is not critical. All that is necessary is that opening door 401 be conveniently located along top panel 50 to provide the consumer with easy access to the contents of the carton. As shown in FIG. 6, opening door 401 is bounded on its right side by perforation line 530, along its top by curved perforation line 520, along its bottom by perforation line 510 and along its left side by a portion of fourth vertical fold line 240. As discussed in more detail below, preferably, that portion of fourth vertical fold line 240 that extends between perforation line 510 and perforation line 520 is perforated. This allows opening door 401 to be completely removed from the carton. Horizontal perforation lines 501 and 502 extend across a top portion, as seen in FIG. 6...
