Referring primarily to FIG. 3, there is shown a flexible packaging bag 50 having a polyhedron shape that defines or forms a polyhedron receiving portion. Specifically, the packaging bag 50 has a polyhedron shape that defines or defines a polyhedron accommodating portion. The packaging bag 50 is defined by a pair of end walls 52, a pair of side walls 54, a top wall 56 and a bottom wall 58. The walls each have a perimeter, such as perimeter 62, for the end wall 52. The walls 52, 54, 56, 58 define an interior space 60 (FIG. 10) for receiving a compressed article stack 64 (FIG. 4), such as underpants 10. The term “compressed articles” or similar terminology indicates that an article stack, such as the underpants 10 of FIG. 4, may have a stacking direction 66 (FIG. 6) to reduce the length dimension 68 of the original uncompressed article. It is compressed inwardly by the compressive force on the front and rear surfaces of the front panel 12 and the rear panel 14, or the front and rear panels in the direction parallel to 4). Compressed laminate 64 also includes a width dimension 70 and a height dimension 72. The term “compression packed” or similar term refers to the condition or condition of the underpants 10 after being compressed and inserted into the packaging bag 50. The term "expansion force" or similar term refers to a force substantially equal to the force generated by the laminate 64 compressed against the end wall 52 in a direction generally opposite and parallel to the direction of the compressive force. Say. Naturally, the walls of the packaging bag 50 all experience some degree of tension.

The packaging bag 50 may be made of other materials, or may be made of substantially the same kind of material. Typically, the material is a polymer film having sufficient flexibility to achieve a generally hexahedral shape when the packaging bag 50 is almost filled with the underpants 10. In addition, the material should have sufficient strength to hold and receive the underpants 10 or other articles without rupture of the film material and without excessive bulging or stretching. For example, the film material may be composed of a polyethylene film or film laminate having a thickness of about 0.0635 mm (about 2.5 mils). Other examples include LDPE (low density polyethylene) films, LDPE / LLDPE (linear low density polyethylene) film laminates, LDPE / MDPE (medium density polyethylene) film laminates, LDPE / HDPE (high density polyethylene) film laminates, and the like. Naturally, the dimensions of the packaging bag 50 depend not only on the desired or artistically good shape, but also on the type of article being stored. Suitable packaging bags and methods of construction thereof are shown and described in US Pat. No. 5,282,687, the contents of which are incorporated herein by reference.

The bag 50 further comprises means in at least one of the walls for accessing the inner space 60 (FIG. 10) for dispensing the underpants 10 from the bag 50. The means for access may be a frangible line that breaks easily. The perforation line 74 (FIG. 3) may be disposed or manufactured at a predetermined position or point on the packaging bag 50 capable of dispensing the underpants 10. As shown in FIG. 3, the perforation line 74 is partially located on one sidewall 54 and runs along the bottom of the bottom wall 58, with the opposite sidewall (at approximately the same distance as the other sidewall 54). 54) upwards. This is also shown in FIG. 10 in which the tear line 74 ruptures to provide an opening 76 for accessing and dispensing the underpants 10. The perforation 74 may, for example, partially cut or thin the thickness of the packaging material in a predetermined pattern, provide a hole of a selected pattern along the required portion or walls of the packaging bag, or along the required line of the packaging bag. By providing a stress-fatigue weakness of the resulting pattern. As shown, the tear line 74 is provided by a series of holes, which can be approximately 2 to 10 holes per inch of straight 2.54 cm (inch).

Referring now primarily to FIG. 4, the underpants 10 are respectively folded such that the elastic side panels 18 (FIG. 1) are disposed inwardly between the front panel 12 and the rear panel 14. As shown in Fig. 4, the underpants 10 generally have opposing side edges 78, top edges 80, bottom edges 82, facing surfaces 84 (only one is shown in Fig. 4) and perimeters. It defines 86. When the underpants are compression packed in the packaging bag 50, the surface 84 faces along the stacking direction 66. Accordingly, the upper edge 80 of the underpants 10 (shown in FIG. 4) is in contact with the bottom wall 58, and the bottom edge 82 of the underpants 10 is connected to the top wall of the packaging bag 50. 56, the side edges 78 of the underpants 10 are in contact with the bag sidewalls 54, and the outermost surface 84 of the end underpants 10 is in contact with the end walls 52. . It should be noted that the bottom edge 82 of the underpants 10 corresponds to the waist opening 22 (FIG. 1).

3 and 10, the packaging bag 50 is opened by rupturing the tear line 74 to access the underpants 10 through the opening 76. Typically, separation of the tear line 74 is initiated by rupturing a portion thereof, followed by tearing along the tear line 74 through the cutout portion of the sidewall 54 and the bottom wall 58 from which the tear line 74 was made. By propagating parts or tears. By rupturing the tear line 74 in this manner, the user can insert a finger or thumb through the opening 76 to access the underpants 10. Next, the user can grasp the top of the underpants 10 to take out the underpants 10 from the bag 50, and the remaining underpants 10 are held in the restraint or the inner space 60.

Referring primarily to FIG. 3, the packaging bag 50 further includes a viewing window 88 disposed or positioned within a portion of the end wall 52. The see-through window 88 includes a see-through periphery 90 having a shape approximately similar to the periphery of the end wall 52. The sight glass 88 generally surrounds at least the components of the underpants 10 contained within the packaging bag 50. In FIG. 3, the components enclosed by the viewing window 88 are part of the graphic 38, which is visually detectable through the viewing window 88. The underpants 10 may have other graphics on the rear panel 14, in which case the end walls 52 are opposed from the end walls 52 with the viewing window 88 surrounding the graphics 38. It may be desirable to have such graphics on the rear panel 14 that are visually detectable through. In this case, the opposite end wall, ie such end wall, which is not seen in Figure 3, also has a viewing window.

Depending on the type of article contained within the packaging bag 50 and components such as graphics of such article, it may be desirable to have a viewing window on a wall different from the end wall 52. For example, if the article stack is packaged in the other direction within the packaging bag 50, either the side wall 54 or the top wall 56 or the bottom wall 58 may have a viewing window in which the components are visually detectable.

Referring to the see-through window 88 that encloses a component such as a graphic 38, the term "framing," substantially framing ", or variations thereof, constitutes the visual periphery for visual display. Within the context of this description, a component is visually detectable if it is transparent or substantially transparent to the viewer. The ability of an object or part of it to transmit light so that it can be seen to be transparent if there are no intervening objects between the component and the individual.The term "substantially clear" allows the light to be transparent, Refers to the ability to cause sufficient light diffusion to eliminate the detection of images, shapes, shapes, etc.

As such, the present invention provides the feature that a user, guardian, or the like can visually view or detect a component or part of the article being purchased, which is particularly desirable when the article is packaged in a packaging bag. The buyer can also view or determine the size of the article, providing a reasonable degree of reliability. This gives both the user and the caregiver product visibility at the time of purchase. For example, in the case where the packaging bag 50 houses the underpants 10, the child may not only see the particular product selected, but also the gender characteristic graphic. This gives the child a subjective and active role in the toilet training process. This is especially important in encouraging children to be trained in toilet law. It is equally important that the guardian can see the desired features or components of the product. For example, if the underpants 10 have a unique outer cover, i.e., a cloth-like texture on both sides, and include a unique design or graphic, the guardian may have a high degree of confidence in the product selected for purchase.

In manufacturing a packaging bag such as a packaging bag 50 for storing and distributing articles such as the underpants 10, a color, an illustration, a letter instruction, on the outermost surface or the innermost surface of the packaging material, It is common to print a manufacturer or the like. In this description, the term “background” or variations thereof refers to a color or ink image that is mainly distinguishable or detectable while surrounding, which is printed on the packaging bag 50. For example, if the underpants 10 are made as sex characteristic underpants, such as the underpants 10 of FIG. 1 and the underpants 42 of FIG. 2, the packaging bag 50 is a blue background color for boys and for girls. It has a pink background color. In this case, the surrounding and mainly detectable or distinguishable color is blue or pink. The term "copy" refers to letter signs, numbers, letters, symbols, artistic pictures or patterns, and the like. Generally, a copy is printed over the background or over an area of the packaging bag 50 where the background is not printed. In the above example where blue for boys is a background, the blue packaging bag 50 may have an illustration printed on the underpants along with other illustrations and textual instructions for proper use.

Similarly, pink packaging bag 50 may have illustrations of girls' underpants as well as instructions for proper use. The term "substantially transparent" refers to a portion of the packaging bag 50 or all of the packaging bag 50 that may have a copy but no background. An example of this is that one of the walls of the packaging bag 50 has no background but includes printed text instructions for use.

Referring primarily to FIG. 3, the packaging bag 50 includes a copy 92, shown generally horizontally. Such a portion of the packaging bag 50 outside the copy 92 may have a background such as printed blue or pink. Finally, looking at the end wall 52 with the sight glass 88, the individual can visually sense the copy 92 and graphics 38, for example blue or pink, text instructions or other data can be recorded. It is to visually see the background 94 such as the see-through window 88.

In some cases where the packaging bag 50 is arranged on a retail shelf, it may not be practical to position the packaging bag 50 so that the viewing window 88 is visible. In such a case, for example, the packaging bag 50 may be located on the shelf space such that one can see the sidewall of one of the sidewalls 54. In order to draw attention to the end wall 52 with the viewing window 88 where the graphic 38 can be seen, a visual cue is arranged or arranged on at least one of the side walls 54. The visual vent 96 is at least substantially transparent and has a lightning shape, for example, as shown in FIG. For the sake of clarity and clarity, the visual vent 96 does not show the side edges 78 (Fig. 4) of the individual underpants 10 housed therein. When the observer sees the visual vent 96, the observer pays attention to the end wall 52 so that components such as graphics 38 of the article, such as underpants 10, can be visually sensed. The visual vent 96 also serves as a product remaining indicator or gauge so that the guardian can easily determine the quantity of underpants 10 remaining in the packaging bag 50.

The visual vent 96 may or may not be continuous with the viewing window 88. That is, as shown in FIG. 3, the visual vent 96 and sight window 88 form a closed loop pattern or perimeter. However, it may be desirable to have a visual vent 96 and sight window 88 provided as separate visible areas for manufacturing, printing, or packaging. In the latter case, the visual vent 96 still serves to draw attention to the sight glass 88 and the graphics 38. As such, the visual vent 96 is visually associated with the sight glass 88 to attract the attention of the buyer, the user, etc. with the sight glass 88 and the graph 38.

Continuing mainly with reference to FIG. 3, the packaging bag 50 further includes an accessory viewing window 98 of the top wall 56. Due to the particular configuration of the packaging bag 50, the top wall 56 includes an upper gusset 100 and the bottom wall 58 includes a bottom reinforcement 102. This particular configuration is described in more detail in US Pat. No. 5,282,687. Regardless of whether the top wall 56 has an upper reinforcement 100, the accessory viewing window 98 allows at least some of the contents of the interior of the underpants 10 and the like to be visually detectable. The accessory viewing window 98 is located or manufactured on a predetermined wall among the walls of the packaging bag 50, but is present in the upper wall 56 so that the user determines the quantity of the inner pants 10 remaining in the packaging bag 50. It is desirable to be able to. It should be noted that there is a seal of the bottom reinforcement 102 as well as a similar seal 104 of the top wall 56 associated with the manufacture of the upper reinforcement 102. The accessory viewing window 98 does not require to be on a particular wall with reinforcement. As with the viewing window 88, the accessory viewing window 98 may be transparent or substantially transparent and may include a copy if it does not interfere with the desired purpose of the accessory viewing window 98. If desired, an accessory viewing window 98 may also be used to attract the attention of the buyer, the user, etc. with the viewing window 88 and graphics 38. The accessory viewing window 98 may take any shape, design, or form that is artistically comfortable or provides a means of attracting attention to the viewing window 88. FIG. 9 shows an accessory viewing window 98 of the top wall 56, and FIG. 8 shows an accessory viewing window 98 extending to the end or end of the top wall 56 adjacent or in contact with the end wall 52. Modifications are shown.

The present invention contemplates various features as shown in the figures. In Fig. 5, the packaging bag 50 is all made of a transparent or substantially transparent material, so that most, if not all, of the individual underpants 10 can be seen. However, it may be necessary to include some copy content, to which extent most underwear 10 can be seen.

6 shows the packaging bag 50 with the sight glass 88 positioned completely within the perimeter of the end wall 52. While copy content 92 is shown, it may be removed if desired. Similarly, see-through window 88 may be transparent or substantially transparent.

FIG. 7 shows another variant in which the end wall 52 is either completely transparent or substantially transparent, such that both the front waist elastic 26 and the front portion of the underpants 10, such as at least part of the graphics 38, appear. Doing.

11 and 12 show a wraparound viewing window 106 of the packaging bag 50. In FIG. 11, the sight glass 106 generally surrounds the four walls of the packaging bag 50, specifically the end wall 52 and the side wall 54. The term “substantially wraps around” means that the viewing window 106 may not be able to continuously wrap around the packaging bag 50 due to manufacturing or sealing requirements. However, it is preferable that the sight glass 106 continuously surrounds the periphery of the packaging bag 50. The wraparound viewing window 106 also checks the remaining amount of the inner pants 10 in the packaging bag 50. In FIG. 12, the sight glass 106 generally surrounds the end wall 52, the top wall 56, and the bottom wall 58.

Although the present invention has been described as having a preferred embodiment, it is to be understood that further modifications are possible. Accordingly, the present invention, which may be or be known or commonly employed in the technical field to which the present invention pertains, is derived from the disclosure of the present invention within the limits of the appended claims, following the general principles of the present invention, It should be construed to include modifications, substitutions, uses, or modifications of the present invention.
