Alternatively, first wing member 70 may have a first end 106 (shown in FIG. 3) that is disposed in second narrow hollow 77 of second wing member 72. In this embodiment, second wall lower portion 100 and first wing member 70 or second wing member 72 define slot 78 and first flap 98 and second flap 104 are tuckable (e.g., insertable) into or tucked into slot 78. Alternatively, neither first end 106 nor second end 108 is tucked into a narrow hollow
In another embodiment, the invention is a method of forming a packet. This embodiment calls for providing substantially square sheet of material 20 having two pairs of opposing corners, preferably the sheet of material illustrated in FIG. 1. In this embodiment, sheet of material 20 has first fold line 32 that extends between a first of said two pairs of opposing corners (corners 24 and 26), first pair of second fold lines 38 and 40 that are disposed substantially parallel to said first fold line, each of said second fold lines being located between first fold line 32 and one of a second of said two pairs of opposing corners (corners 28 and 30), a second pair of third fold lines (fold lines 38 and 40) that are disposed substantially parallel to first fold line 32, each of said third fold lines (fold lines 38 and 40) being located between one of said of second fold lines (fold lines 38 and 40) and one of said second of said two pairs of opposing corners (corners 28 and 30), and a third pair of fourth fold lines (fold lines 34 and 36) that are disposed substantially perpendicular to first fold line 32, each of said fourth fold lines 34 and 36 being located between a line connecting said second of said two pairs of opposing corners (corners 28 and 30) and one of said first of said two pairs of opposing corners (corners 24 and 26). The next step involves folding sheet of material 20 along first fold line 32 to produce a substantially triangular structure 50 having two tips 70 and 72 and flap 74. The next step involves folding each of said tips 70 and 72 along one of said fourth fold lines 34 and 36 and engaging tips 70 and 72 with one another when in a folded condition to produce open packet 54 having opening 75 and slot 78. The next step involves folding open packet 54 along said second fold lines to produce a closed packet 10. The next step involves folding closed packet 10 along said third fold lines to produce secured packet 10 when flap 72 is inserted into slot 78.
In another preferred embodiment, the invention is a square, gloss text weight (paper), sheet 20 of paper folded to make packet 10. Packet 10 is preferably provided in various sizes, ranging from one by one inch squares to eight by eight inch squares (the dimensions given being those of the unfolded square of paper). The paper used is preferably similar to that used in color magazines. The paper is preferably slightly thicker than an inside page of a color magazine, but not as thick as a common color magazine cover.
In total, in a preferred embodiment, there are five folds needed to complete the packet. The completely folded packet preferably has a rectangular shape. Each sheet 20 is preferably pre-folded and unfolded so that the user can easily put an object inside the packet and secure it. Sheet 20 folds into be a self-closing packet 10, holding the object placed inside tightly. Packet 10 is preferably sold creased, but unfolded, so the user can easily put the object inside packet 10 and fold it themselves. Unfolding a packet 10 also makes it easer to stack a plurality of them, as they can be placed one on top of another. In preferred embodiments, strict attention is paid to the location of each fold. Preferably, each sheet 20 is pre-creased by machine.
The area on sheet 20 which is not visible to a user after the first fold takes place is the inside of packet 10. The area on sheet 20 which is visible after the first fold takes place is the outside of packet 10. The outside of packet 10 may be colored or may comprise pictures or advertising to better distinguish among the different sizes offered. The area on the inside of packet 10 may be black or another dark color, or comprise a picture or advertising. One preferred size for sheet 20 is 2 13/16 inches by 2 13/16 inches. The other preferred sizes are in the range from 1½ inch by 1 1/2 inch to 4 inch by 4 inch. In one embodiment, 80 pound gloss paper is preferred. Preferably, the 2 13/16 inch by 2 13/16 inch size is white on the outside, and other sizes have different colors on the outside. In a preferred embodiment, a logo of applicants' company, EZFlaps.com, is placed on the outside of the each packet 10. Alternatively, one of three designs (e.g., martini glass, crown and diamond) is printed on the outside of packet 10 in a specific region that is visible when packet 10 completely folded. The designs are used so the user can tell by looking at a packet what he/she put inside. After colors, logo and design are printed on sheet 20, both sides of sheet 20 are preferably varnished. The varnish is any coating used to seal in the color, make the sheet less water-absorptive and keeps the color from flaking off at the creases.
Preferred embodiments of the invention are used to hold one or more small objects for a user. Packet 10 may be used to hold individual prescription pills for an elderly person who does not want to carry around an entire bottle of pills. Packet 10 may also be used hold candies. It can hold relatively any small object the possessor wishes to keep separate from other objects. Packet 10 can also be used in childrens' games, such as those disclosed at WWW domain EZFlaps.com, the disclosure of which games is incorporated by reference as if fully set forth herein.
Many variations of the invention will occur to those skilled in the art. Some variations are foldable kits. Other variations are machine produced. All such variations are intended to be within the scope and spirit of the invention.
Although some embodiments are shown to include certain features, the applicant specifically contemplates that any feature disclosed herein may be used together or in combination with any other feature on any embodiment of the invention. It is also contemplated that any feature may be specifically excluded from any embodiment of the invention.
