- This reinforcement member 400 also helps to redistribute the load evenly across the width of the bag.

However, as shown in FIG. 4 , the reinforcement member 400 is shown by way of an example to be shorter than the full width of the bag. The bag shown in FIG. 4 thus has a lighter load capacity than a bag where the reinforcement member is the full width of the bag.

Abstract
Ordinary bags are made of either paper or plastic material. Due to a puncture of the bag, the point of puncture quickly becomes a ripping point to further enlarge an originally small opening. The present invention overcomes this shortcoming of ordinary bags by using a new material that is produced by adhering a web material with a base material. The web material would effectively serve as a safety net to prevent further ripping of the bag once the base material of the bag is punctured.
Description
- The present invention is related to the field of bags. More specifically, the bag of the present invention is made of a textural material that enhances both the durability and the ornamental appeal of the bag.
- Conventional foldable bags have been in the marketplace for many years. They are typically shaped as shown in various figures of U.S. Pat. No. 6,000,849 issued to Keller; U.S. Pat. No. 6,146,618 issued to Keller; U.S. Pat. No. 6,345,912 issued to Ho; U.S. Pat. No. 6,737,959 issued to Ho; U.S. Pat. No. 6,749,064 issued to Alrey; U.S. Pat. No. 5,836,095 issued to Crowell; U.S. Pat. No. 6,045,263 issued to Keller; U.S. Pat. No. 5,613,312 issued to Crowell; U.S. Pat. No. 6,045,263 issued to Keller; U.S. Pat. No. 5,613,312 issued to Crowell; and U.S. Pat. No. 5,441,348 issued to Valentino. These foldable bags are generally made of paper or plastic.
- While thick paper sheets are able to withstand acceptable amount of load and stress, the material strength of paper deteriorates substantially when used repeatedly, when it becomes wet, or when it is punctured. As individual fibers making up a paper sheet becomes wet, they tend to absorb the water in their surrounding until the amount of absorption reaches a saturation point. Moisturized or soaked fibers swell up and expand in size. Due to this fiber expansion, the frictional force holding numerous fibers together would become weaken as contact surfaces of the fibers decreased. In addition, each of the individual swelled fibers also disintegrates and allows the paper sheet to become more susceptible to tears. Consequently, the durability of a bag made of paper material greatly deteriorates once it is soaked with liquid or when it is used in a humid environment.
- Generally, an un-punctured paper bag is highly resistant to tears due to various types of tear resistant barriers designed into the bag. However, once a puncture or cut exist on the paper bag, the paper bag is highly susceptible to tears, hence enlargement of the puncture or cut. It is often the case that once a layer of a paper bag is punctured by a foreign object, such as by an object stored in the bag, the weight of the foreign object tends to travel downward due to gravitational pull. As the foreign object travels downward beginning from the point of penetration of the paper bag, the initially small opening is enlarged because the amount of gravitational pull is greater than the tear tolerate point of the paper. As the opening is enlarged, other objects stored therein the bag would also fall out of the paper bag due to gravitational pull. Therefore, the paper bag is rendered useless.
- Foldable bags made of plastic materials tend to be very resistant to deterioration when exposed to liquid or moisture. However, plastic provides a less rigidity characteristic than paper. A paper bag can maintain its form and rigidity even used under higher load than it is designed to withstand. Upon removal of the load, it is better able to return to its original shape and condition. Overall, a paper bag when used in dry conditions and used under loads slightly higher than it is designed to withstand would not be permanently damaged.
- On the other hand, a plastic bag demonstrates very little rigidity and when used under a load slightly more than it is designed to withstand, it would begin to deform. Once any deformation occurs in a plastic bag material, the deformation becomes permanent. Upon removal of an object asserting the load, deformed plastic materials do not return to their pre-deformed shapes and conditions.
- Furthermore, since plastic has a more uniformed molecular structure than paper, once there is a small puncture or a cut in the plastic bag, it requires very little amount of force to rip a plastic sheet wide open.
- Therefore, both paper bags and plastics bags have serious shortcomings in that they are incapable to resist tears once they are punctured or cut.
- An objective of the present invention is to overcome the above-discussed shortcomings of bags that are conventionally made of paper material and plastic material.
- Another object of the present invention is to manufacture a new material by adding a web material to a plastic material, a paper material and a foil material, etc.
- A third object of the present invention is to manufacture bags that are able to withstand higher loads and higher stresses than conventional bags.
- A fourth object of the present invention is to make bags that are more resistant to tears once they are penetrated or cut by an object.
- A fifth object of the present invention is to manufacture bags using a new material unknown among conventional bag making materials.
- A sixth object of the present invention is to provide a safety net on the bag so as to prevent objects from falling out of the bag even if the bag is torn or punctured.
- A seventh object of the present invention is to use the new material as a communication medium to convey seasons of the year, occasions the bag is suited for and sentiments associated with the use of the bag.
- Other objects of the present invention will become more apparent upon review of the explanations given hereinunder.

FIGS. 12-14 illustrate several perspective views of a number of bags made with the new material where the web material serves as a safety net of the base material. - A new material is manufactured by adhering a web material onto a base material. The web material may be material formed by weaving, knitting, pressing, or felting natural or synthetic fibers; a net, a lace, an allover lace or tulle knitted of either polyester, nylon, rayon, lurex, metallic wire, yam or a combination thereof. The manner in which the adhering of the web material and the base material, and post processing thereof is performed as shown by way of an example in
FIG. 6 . As shown, there are 11 manufacturing stages divided into stations 1-11. - In station 1, a roll of a
web material 601 is suitably installed onto aholding roller 600. The roll of web material is biased between a stabilizingroller 602 and the holdingroller 600 to minimize any other motions so as to ensure and isolate a rotating motion about the holdingroller 600. The roll ofweb material 601 is also biased between the holdingroller 600 and a drivingroller 608 driven by amotor 604 via a drivingshaft 606 and a drivingbelt 607. As the drivingroller 608 frictionally rotates the roll ofweb material 601, the roll of web material is unwrapped and the unwrapped material travels toward a directing roller 610 in bonding station 4. - In station 2, a roll of
base material 611 is suitably installed onto asecond holding roller 612. Any unwrapped basedmaterial 611 is guided by assistingrollers 614 and 616 to travel over anadhesive application roller 618 in an adhesive application station 3. Both theweb material 601 and thebase material 611 are fed between asecond biasing roller 622, a second stabilizingroller 620 and asecond driving roller 624. Thesecond driving roller 624 is driven by asecond motor 626 via abelt 628, inslitter station 5. As theweb material 601 and thebase material 611 traveled through thesecond biasing roller 622, thesecond stabilization roller 620 and thesecond driving roller 624, they are pressed by the rollers and held together by adhesives applied by theapplication roller 618. A new material is thus formed. - Depending upon specific applications the new material is being prepared for, peel and stick materials such as for lace or ribbon may be added onto the new material by
installation rollers 630 inslitter station 5. Even though four rollers are shown to make upinstallation rollers 630. The number of actual rollers and the width of a roller may be altered depending upon specific needs. - Stations 6-11 are post processing stations to cut and prepared the new material for specific applications.
Station 6 is a sheeting cutting station. Station 7 is a BOPP sheets accumulating station. Station 8 is another bag cuffing station.Station 9 is a cut sheet accumulating station.Station 10 is a new material based packaging station. Station 11 is a bag forming station. - Either of the roll of
web material 601 or thebase material 611 can be installed onto holdingrollers web material 601 orbase material 611. In the illustrated example, the basedmaterial 611 is applied with adhesives. As thebase material 611 is a long planar sheet of paper material, plastic material, foil material, etc., adhesives are applied onto the entire surface of the base material when coming in contact with theadhesive application roller 618. This would provide an advantageous effect in that a coding is being uniformly applied to the entire surface of the base material. This coding may produce a shade of sheen, a color scheme, an insulating layer, a reinforcement layer, a combination thereof, or other characteristics desirable for the application of the new material. - Alternatively, if the roll of
web material 601 is installed onto the holdingroller 612, adhesives will be applied only to the surface contact side of the web material formed by weaving, knitting, pressing, or felting natural or synthetic fibers, lace, tulle, allover lace, net, etc. This would provide an advantageous effect in that since a web material contains many devoids thus it would have much less contact surface area than a planar sheet of base material. Consequently, less adhesive is being used. Therefore, applying adhesives to the web material is an economical alternative of applying adhesives to the base material. -
FIG. 7 illustrates a representative cross-sectional view of an adhesive 702 being sandwiched in-betweenweb material 700 andbase material 704. It should be noted that the thickness of the adhesive 702,web material 700 andbase material 704 may not be the same. How much difference in thickness between these materials depend upon specific web material, base material and adhesive that are being used. - New materials successfully made by adhering web materials with base materials are shown by way of examples in
FIGS. 8, 9 , 10 and 11. As shown inFIG. 8 , a green, white and red web material is adhered to a white base material. This overall color scheme and pattern configuration is communicative of the Christmas season. Thus a bag made of this new material can be fashionably used during the Christmas season. -
FIG. 9 is shown a brown and rice color web material being adhered to a pink base material. As pink is typically associated as a feminine color, this new material is communicative that the user of a bag made of this new material is either a female or the content stored therein the bag is designated for a female recipient. -
FIG. 10 is shown a blue web-material with leave and web patterns being adhered onto a white base material. Given that web material with leaves are preferred by females yet blue is a generally a masculine associated color, this color scheme and web pattern communicates that this new material may be used by either gender. -
FIG. 11 is shown a white floral web material being adhered onto a deep maroon base material. As both the floral arrangement and the deep maroon color are more preferred by females. The use of this material would be communicative that any contents encompassed therein would be designated for a female recipient. - To make a
foldable bag 500 as that shown inFIG. 5 , the process starts from establishing a pattern on a piece of material as shown by way of an example inFIG. 1 . As clearly shown, there are three different types of dash-lines, one type is composed of only a series ofdots 114, another type is composed of a series of dashes anddots 112 and yet another type is composed of a series of long dashes 113. These three types of dash-lines signify a difference in folding directions. If a series of dots of dash lines signifies that portions parallel to the dash lines are to be folded into the paper ofFIG. 1 , then the series of dash lines and dots signifies that portions parallel to the dash lines and dots are to be folded out of the paper ofFIG. 1 . For our example,dash line 114 signifies folding both portions parallel to the dash line into the paperFIG. 1 and dashline 112 signifies folding both portions parallel to the dash line out of the paper ofFIG. 1 . - The series of long dash lines signifies that due to multiple layers of folding, portions parallel to this series of long dash lines may fold either into or out of the paper
FIG. 1 . - The numerous dash lines nicely divide the rectangular shape
new material 100 into different zones. As shown, there are aheader zone 102, abody zone 104, afooter zone 106, a first flat-side zone 118, a second flat-side zone 120, afirst folding zone 108, asecond folding zone 110, and atap zone 122. - Located on each of the first flat-
side zone 118 and the second flat-side zone 120 are fourstring holes header zone 102 to be flush with thebody zone 104,holes header zone 102 would correspondingly meetholes body zone 104. - Exact and predetermined placement of string-
holes bag 500 can be uniformly shared across the full width of the bag, then placement of these holes should observe the characteristics of d3=d4=d1. - In a situation where the load is not of the same foot print as that of the bag and the load tends to concentrate in the mid-width portion of the bag, then placement of these holes should observe the characteristics d3<d1, d4<d1 and d3=d4.
- In a situation where the load is not of the same foot print as that of the bag and the load tends to concentrate on one side of the bag, then placement of these holes should observe the characteristics d1<d3, d1<d4 and d3=d4.
- These string-holes may be individually created on the header zone and the body zone. They can also be created after the header zone is folded into the body zone. They can further be created after a reinforcement member 400 is adhered in-between the header zone and the body zone.
- As bags are manufactured in different sizes; generally, the larger is the size of the bag, the more important it is to correctly choose the placement of the string-holes. However, depending on the size and weight of the load, these horizontal string-hole placement considerations are also applicable to smaller size bags.
- Vertical placement of string-holes 1 16, 124, 126 and 128 should observe characteristics that d2=d6 and d2>d5. This is to compensate for the fact that while the material at the rim of these holes experience the most amount of compressive force, the edge of the material above these holes experience the most amount of tensile force, due to the load. In addition to the concerns over the placement of the ring-holes, a reinforcement member 400 should also be added in-between the
header zone 102 and thebody zone 104. This reinforcement member helps regions surrounding string-holes FIG. 4 , the reinforcement member 400 is shown by way of an example to be shorter than the full width of the bag. The bag shown inFIG. 4 thus has a lighter load capacity than a bag where the reinforcement member is the full width of the bag. - It is preferred that the reinforcement member 400 be adhered in-between the
header zone 102 and thebody zone 104, this would further ensure that all surfaces coming into contact with the reinforcement member 400 evenly share the load and evenly distribute sharing of the load to other zones of the bag. -
FIG. 2 illustrates a bottom view ofmaterial 100 that is being folded along various fold lines.Points lines tap 122 is adhered to an inner surface of the first flat-side zone 118. The larger is the size of thetap 122, the more surface contact will there be between thetap 122 and the first flat-side zone 118. The stronger will also be the integrity of the bag. Given that thenew material 100 has a web side, the devoid spaces formed by the web patterns effectively create an adhesive retaining pool, so that greater amount of adhesives may be used to provide a stronger hold of two contacting surfaces. This retaining pool feature also contributes to the making of a stronger bag. -
FIG. 3 provides another bottom view showing the footer zone being folded along various long dash lines to form a closure end. Specifically, the closure end is made by folding a first bottom edge of thefirst folding zone 110 and a second bottom edge of thesecond folding zone 108 toward each other so that the first and second bottom edges are substantially parallel. Then there is further folding of a third bottom edge of the first flat-side zone 118 and a fourth bottom edge of the second flat-side zone 120 toward each other to form a first closure tab and a second closure tab in a way that the third and fourth bottom edges are substantially parallel and overlapping each other. The closure end is finalized by adhering the first closure tab to the second closure tab wherein the web material on one of the first closure tab and the second closure tab form a retaining wall to retain a pool of adhesives when the first closure tab is adhered to the second closure tab at the overlapping surfaces. - Again, due to the presence of web patterns to retain a greater amount of adhesive material, the closure end of the present invention is much stronger than conventional closure ends without the benefit of the retaining wall to retain a pool of adhesives.
- There is a supporting plate member (not shown) placed on the bottom of the bag yet residing above the closure end. This supporting plate member is of substantially the same size as the bottom of the bag. It provides further rigidity and load bearing capacity to the bottom of the bag.
- From the foregoing detailed description, it will be evident that there are a number of changes, adaptations and modifications of the present invention that come within the province of those persons having ordinary skill in the art to which the aforementioned invention pertains. However, it is intended that all such variations not departing from the
