Abstract

The disclosed packaging containers may include a body including a sidewall and at least one top flap for at least partially covering an opening of the body when assembled and perforations in the sidewall of the body. The perforations may include a lower perforation having a first end portion and a second end portion; a first side perforation extending upward toward the top flap from the first end portion of the lower perforation; and a second side perforation extending upward from the second end portion of the lower perforation, wherein the first side perforation and the second side perforation converge toward each other as they extend upward from the lower perforation. Various other packaging containers, systems, and methods are also disclosed.

First claim

What is claimed is:

1. A packaging container, comprising:
a body including a sidewall and at least one top flap for at least partially covering an opening of the body when assembled; and
perforations in the sidewall of the body, the perforations including:
a lower slit parallel to the top flap and having a first end portion and a second end portion;
a first side perforation extending upward toward the top flap from the first end portion of the lower slit;
a second side perforation extending upward toward the top flap from the second end portion of the lower slit, wherein the first side perforation and the second side perforation converge toward each other as they extend upward from the lower slit, wherein the first side perforation and the second side perforation converge to reach each other at a pointed apex;
a first bottom slit extending downward from the first end portion of the lower slit away from the top flap; and
a second bottom slit extending downward from the second end portion of the lower slit away from the top flap, wherein the lower slit, the first bottom slit, and the second bottom slit define three sides of a lower flap.

2. The packaging container of claim 1 , wherein the perforations are, as a group, positioned in a laterally central position in the sidewall.

3. The packaging container of claim 1 , wherein the lower slit comprises a single slit extending from the first end portion to the second end portion.

4. The packaging container of claim 1 , wherein the lower slit has a length of at least about 1.5 inches.

5. The packaging container of claim 1 , wherein the apex defines an acute angle between the first side perforation and the second side perforation.

6. The packaging container of claim 1 , wherein each of the first side perforation and the second side perforation is linear.

7. The packaging container of claim 1 , wherein the lower slit, first side perforation, and second side perforation define a removable flap therebetween.

8. The packaging container of claim 7 , wherein the removable flap has a triangular shape.

9. The packaging container of claim 7 , wherein the removable flap is located on the sidewall below the opening.

10. The packaging container of claim 9 , wherein a distance between the opening and the removable flap is at least about 1.0 inch.

11. The packaging container of claim 1 , wherein the at least one top flap comprises two top flaps configured to fold toward a center of the opening.

12. The packaging container of claim 1 , wherein the body comprises a cardboard body.

13. A method of forming a packaging container, comprising:
forming a body to include a sidewall and at least one top flap for at least partially covering an opening of the body when assembled; and
forming a removable flap in the sidewall, comprising:
cutting the sidewall to form a lower slit parallel to the at least one top flap when assembled and having a first end portion and a second end portion;
cutting the sidewall downward from the first end portion of the lower slit away from the top flap to form a first bottom slit;
cutting the sidewall downward from the second end portion of the lower slit away from the top flap to form a second bottom slit, wherein the lower slit, the first bottom slit, and the second bottom slit define three sides of a lower flap;
perforating the sidewall upward toward the top flap from the first end portion of the lower slit to form a first side perforation; and
perforating the sidewall upward toward the top flap from the second end portion of the lower slit to form a second side perforation, wherein the first side perforation and the second side perforation converge toward each other as they extend upward from the lower slit, wherein the first side perforation and the second side perforation converge to reach each other at a pointed apex.

14. The method of claim 13 , wherein perforating comprises at least one of: forming a single slit, or forming a series of slits or holes.

15. The method of claim 13 , wherein:
cutting the sidewall to form the lower slit comprises forming a single slit between the first end portion and the second end portion;
perforating the sidewall to form the first side perforation comprises forming a first series of multiple slits or holes; and
perforating the sidewall to form the second side perforation comprises forming a second series of multiple slits or holes.

16. A method of securing a packaging container, the method comprising:
closing at least one top flap over an opening of the packaging container, the packaging container comprising a body including a sidewall and the at least one top flap;
adhering tape over the top flap to secure the top flap in a closed position; and
positioning an end of the tape over a removable flap formed in a sidewall of the packaging container, wherein the removable flap is defined by:
a lower slit parallel to the at least one top flap and having a first end portion and a second end portion;
a first side perforation extending upward toward the top flap from the first end portion of the lower slit; and
a second side perforation extending upward toward the top flap from the second end portion of the lower slit, wherein the first side perforation and the second side perforation converge toward each other as they extend upward from the lower slit, wherein the first side perforation and the second side perforation converge to reach each other at a pointed apex;

wherein the removable flap is positioned above a lower flap, defined by:
the lower slit;
a first bottom slit extending downward from the first end portion of the lower slit away from the top flap; and
a second bottom slit extending downward from the second end portion of the lower slit away from the top flap.

17. The method of claim 16 , wherein positioning the end of the tape over the removable flap comprises positioning the end of the tape over a triangular removable flap.
