BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring now to the drawings, in

FIGS. 1 and 2

is shown a first embodiment of the storage bag of the invention generally indicated by the numeral


10


. Bag


10


has a front panel


12


and a rear panel


14


which are preferably made from a single, integral piece of plastic film Front panel


12


is joined to rear panel


14


by side seams


16


and


18


and by bottom fold


20


. Side seams


16


and


18


have lower tapered portions


16




a


and


18




a


could be deleted and seams


16


and


18


could intersect bottom


20


perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions


16




a


and


18




a


could be shaped like an arc or a portion of an ellipse.




Front panel


12


has a top edge


12




b


which is not connected to rear panel


14


, and rear panel


14


has a top edge


14




b


which is not connected to front panel


12


. Top edge


14




b


is located at a distance above top edge


12




b


to form lip


14




a


. Rear panel may have wicket holes


14




c


adjacent the top edge


14




b


if desired for stacking the bags as is known in the art. If desired, top edge


12




b


and top edge


14




b


could lie immediately adjacent to each other, and lip


14




a


and wicket holes


14




c


could be eliminated.




Thus, an opening


22


shown in

FIG. 2

is formed in the top end of bag


10


. Goods such as poultry, beef, vegetables, chemicals, blood or pathological specimens, or any other fluid exuding item may be inserted into the inside


24


of bag


10


through opening


22


. Preferably, bag


10


is used to contain and store poultry. The poultry may be whole such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings.




Located inside bag


10


is an enclosure made from plastic film generally indicated by the numeral


26


for loosely containing the fluid absorbing pad


28


and liquids emanating from goods stored in bag


10


. Although it is preferred that fluid absorbing pad


28


may be loosely contained or held in enclosure


26


and therefore be free to move therein, pad


28


could be connected to enclosure


26


to prevent movement therein if desired.




Enclosure


26


is connected at seam


26




a


to front panel


12


and at seam


26




b


to rear panel


14


. Preferably, enclosure


26


is connected along its sides


26




c


and


26




d


shown in

FIG. 3

to side seams


16


and


18


of bag


10


and to tapered portions


16




a


and


18




a


. However, if desired, enclosure


26


could be narrower than the width of bag


10


.




In

FIGS. 1 and 2

, seams


26




a


and


26




b


are shown connected to front panel


12


and rear panel


14


, respectively, at approximately the same distance from the bottom fold


20


of bag


10


. If desired, seam


26




b


could be located a greater distance from the bottom fold


20


than seam


26




a


to coincide with the borders of printed matter that may appear on the front panel


12


of bag


10


. Furthermore, if desired, seam


26




a


or


26




b


could be located adjacent to bottom fold


20


.




Fluid absorbing pad


28


is also referred to in the art, and sometimes herein, as a “soaker pad” soaker pads are well known in the art and may be made from a variety of fluid absorbing materials. Soaker pad


28


may be made from manufactured or synthetic fibers, or natural fibers, or a combination thereof, either woven or non-woven, which are secured or attached to each other. Preferably, the absorbent material fibers of the fluid absorbing pad or soaker pad


28


are formed from cellulose materials such as paper or the like.




It is not necessary that the soaker pad


28


be covered with plastic film as disclosed in U.S. Pat. No. 5,055,332 and the like, because the soaker pad utilized in the present invention is contained in plastic film enclosure


26


and will not come in direct contact with the goods contained in bag


10


. Thus, inexpensive soaker pads


28


made from absorbent materials having no plastic film cover attached thereto may be used in the bag


10


of the present invention.




Enclosure


26


has a plurality of perforations


30


which are substantially uniform over its full area. The perforations


30


permit liquids to travel therethrough from the goods contained in bag


10


to the soaker pad


28


. Soaker pad


28


absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad


28


are retained within the enclosure


26


which functions as a fluid sump or reservoir.




Enclosure


26


shown in

FIGS. 1-3

is preferably treated with antimicrobial agents to suppress or kill bacteria, fungus, and algae such as Staphylococcus, Psiudomonas, Proteus,


Escherichia coli


, Salmonella, Streptococcus, Enterobacter, Bacillus, Chaitomium, Myrothecium, Aspergillus, Penecillium, Fusarium, Alternaria, Aureobasidium, and other known microorganisms that may be found in the fluids or liquids emanating from the goods stored inside bag


10


. Enclosure


26


acts as a microbial filter within bag


10


whereby some or all of the microorganisms found in the liquids passing therethrough are killed so that any liquids that are trapped therein are prevented from causing spoilage or contamination to the stored product. This novel feature of bag


10


is an important advance in the art of packaging where the products being stored in bag


10


must be kept free from potentially dangerous or hazardous microorganisms. It will be appreciated by those in the art that bag


10


with its unique perforated enclosure


26


that has been treated with antimicrobial agents, so as, to act as a microbial filter to eliminate some or all of the microorganisms present within bag


10


solves a well known problem.




Enclosure


26


can be conveniently treated with antimicrobial agents by blending concentrates such as Ultra-Fresh DM-50 or 95 directly into the raw materials used to produce the enclosure film, by preferably utilizing the polymeric extrusion process. Ultra-Fresh 95 is a registered trademark of Thompson Research Associates of Toronto, Canada a division of Kroy Wools Ltd. and is a concentrated additive composed of active ingredients including Diiodomethyl-p-toyl sulfone. Ultra-Fresh DM-50 is a registered trademark of Thompson Research Associates and Kroy Wools Ltd. and is a concentrated additive composed of active ingredients including Tri-n-butyltin maleate. Other well know additives can be utilized as the antimicrobial agent of the present invention such as products supplied by Microban Products Company of Huntsville, N.C. The amount of concentrate to be added to a particular polymer blend for the control of specific microorganisms such any of those listed above should be recommended by the additive supplier such as Thompson Research Associates or Microban Products Company.




The soaker pad


28


shown in

FIGS. 1-3

could be treated with antimicrobial agents to control the spread of microorganism such as those specifically listed above by using the techniques previously described for treating enclosure


26


of

FIGS. 1-3

. Although the materials that form the absorbent medium of soaker pad


28


could be treated by utilizing concentrates containing the active ingredients such as Diiodomethyl-p-toyl sulfone and Tri-n-butyltin maleate other additives and methods for treating soaker pad


28


also are known in the art and therefore could be utilized as well.




Referring now to

FIGS. 4 and 5

, there is shown a second embodiment of the storage bag of the invention generally indicated by the numeral


110


. Bag


110


has a front panel


112

a


and


218




a


could be deleted and seams


216


and


218


could intersect bottom


200


perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions


216




a


and


218




a


could be shaped like an arc or a portion of an ellipse.




Front panel


212


has a top edge


212




b


which is not connected to rear panel


214


, and rear panel


214


has a top edge


214




b


which is not connected to front panel


212


. Top edge


214




b


is located at a distance above top edge


212




b


to form lip


214




a


. Rear panel may have wicket holes


214




c


adjacent the top edge


214




b


if desired for stacking the bags as is known in the art. If desired, top edge


212




b


and top edge


214




b


could lie immediately adjacent to each other, and lip


214




a


and wicket holes


214




c


could be eliminated.




Thus, an opening


222


shown in

FIG. 7

is formed in the top end of bag


210


. Goods such as poultry, beef, vegetables, or any other fluid exuding item may be inserted into the inside


224


of bag


210


through opening


222


. Preferably, bag


210


is used to contain and store poultry. The poultry may be whole, such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings.




Bag panels


212


and


214


of bag


210


shown in

FIGS. 6 and 7

could be treated with antimicrobial agents, to control the spread of microorganism found in bag


210


, by using the techniques previously described for treating enclosure


26


of

FIGS. 1-3

.




Located inside bag


210


is an enclosure made from plastic film generally indicated by the numeral


226


for loosely containing the fluid absorbing pad


228


, and liquids emanating from goods stored in bag


210


. fluid absorbing pad


228


is placed between the rear panel


214


and the enclosure


226


. A space or reservoir


229


exist between front panel


212


and enclosure


226


in space


229


. Although it is preferred that fluid absorbing pad


228


may be loosely contained or held in enclosure


226


and therefore be free to move therein, pads


228


and


229


could be connected to enclosure


226


to prevent movement therein if desired




Enclosure


226


is connected at seam


226




a


to front panel


212


and at seam


226




b


to rear panel


214


. Preferably, enclosure


226


is connected along its sides in the same manner as enclosure


26


, shown in

FIGS. 1

,


2


, and


3


, to side seams


216


and


218


of bag


210


and to tapered portions


216




a


and


218




a


. However, if desired, enclosure


226


could be narrower than the width of bag


210


.




In

FIGS. 6 and 7

, seams


226




a


and


226




b


are shown connected to front panel


212


and rear panel


214


, respectively, at approximately the same distance from the bottom fold


220


of bag


210


. If desired, seam


226




b


could be located a greater distance from the bottom fold


220


than seam


226




a


to coincide with the borders of printed matter that may appear on the front panel


212


of bag


210


. Furthermore, if desired, seam


226




a


or


226




b


could be located adjacent to bottom fold


220


.




Fluid absorbing pad


228


is also referred to in the art, and sometimes herein, as a “Osaka pad”. Soaker pad


228


may be constructed from the same materials and in the same manner as soaker pad


28


in

FIGS. 1-3

.




The soaker pad


228


shown in

FIGS. 6 and 7

could be treated with antimicrobial agents to control the spread of microorganism such as those specifically listed above by using the techniques previously described for treating enclosure


26


of

FIGS. 1-3

.




Enclosure


226


has a plurality of perforations


230


which are substantially uniform over its full area. The perforations


230


permit liquids to travel therethrough from the goods contained in bag


210


to the soaker pad


228


. Soaker pad


228


absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad


228


are retained within the enclosure


226


and reservoir


229


which functions as a fluid sump or reservoir.




The enclosure


226


as shown in

FIGS. 6 and 7

is preferably treated with antimicrobial agents to control the spread of microorganism such as those specifically listed above by using the techniques previously described for treating enclosure


26


of

FIGS. 1-3

.




In

FIG. 8

is shown the preferred method of producing soaker pad web material


300


shown in

FIG. 9

with soaker pads


328


sandwiched between bag film


315


and perforated enclosure material


325


. The preferred method of producing soaker pad web material


300


requires a continuous supply of opaque perforated plastic enclosure material


325


be fed forwardly in a bag forming direction Perforated enclosure material


325


could be produced by feeding a transparent or opaque plastic web material


323


through a mechanism


350


capable of creating perforated holes


330


through material


323


. Mechanisms such as mechanism


350


are well known in the art whereby the perforated holes


330


are normally produced by mechanical punching or electrically burning through the web material in the desired locations. Any device known in the art for producing perforated film could be used with the present invention.




After plastic web material


323


has been perforated producing perforated enclosure material


325


, soaker pads


328


are individually cut from preferably a continuous roll of soaker pad material


327


by mechanism


360


and placed upon the perforated enclosure material


325


as it is moved forward Mechanism


360


includes preferably a rotary cutting device


362


for feeding and cutting off enough soaker pad material


327


to produce soaker pads


328


. Soaker pads


328


after being cut off of the roll of soaker pad material


327


are preferably moved from rotary cutter


362


and positioned on perforated enclosure material


325


by vacuum wheel


364


which creates suction pressure at vacuum wheel head


365


through vacuum holes


366


. As vacuum wheel


364


rotates the suction pressure decreases so that the soaker pad


328


is released from the vacuum head


365


and deposited onto the perforated enclosure material


325


in the desired location. Mechanisms such as mechanisms


360


and


364


are well know in the art. Other mechanisms well known in the art for delivering and positioning soaker pads onto a surface could also be used, such as mechanisms that deliver and position precut soaker pads from a magazine. Any device known in the art for cutting and supplying soaker pads onto a surface could be used with the present invention. Alternatively, the enclosure material


325


and the bag film


315


could exchange place with each other in FIG.


8


and the soaker pad


328


would be positioned onto the bag film


315


by the soaker pad positioning and cutting mechanism


327


prior to the two web materials being sealed together as previously described above.




After the soaker pads


328


have been cut and positioned onto the perforated enclosure material


325


, a continuous layer of preferably printed transparent bag film


315


is laid over the perforated enclosure material


325


thereby sandwiching the soaker pads


328


between the bag film


315


and the enclosure material


325


. The width of the bag film


315


is preferably substantially wider than the width of the enclosure material


325


resulting in the enclosure material edges


325




a


and


325




b


being connected to the surface of the bag film


315


a substantial distance away from the bag film edges


315




a


and


315




b.






As the enclosure material


325


, containing the soaker pads


328


and the bag film


315


, are fed forwardly, the enclosure material edges


325




a


and


325




b


are connected by heat sealing mechanism


370


to the surface of the bag film


315


forming seams


326




a


and


326




b


shown in FIG.


9


. The seams


326




a


and


326




b


are formed adjacent to the edges


325




a


and


325




b


of enclosure material


325


. Heat sealing mechanism


370


includes heat sealing devices


371


and


372


that seal the enclosure material edges


325




a


and


325




b


to the surface of the bag film


315


at seams


326




a


and


326




b


as they pass across back-up drum


375


. Mechanisms such as mechanism


370


are well known in the art whereby some such mechanisms utilize devices to heat seal materials together by making direct contact to the materials to be connected while others do not make direct contact with the materials to be sealed but instead generate hot air to cause the materials to melt thereby heat sealing them together. Any device known in the art of heat sealing polymeric materials together could be utilized as the device to connect the materials together in the method of the present invention.




In addition to connecting the enclosure material


325


and the bag material


315


together at seams


326




a


and


326




b


, enclosure material


325


and bag material


315


could also be connected by several spot connections such as spot connections


377




a


and


377




b


formed conventional sealing mechanism


376


. The spot connections


377




a


and


377




b


would prevent the soaker pads


328


from sliding between the surfaces of the enclosure material


325


and the bag film


315


along an axis parallel to the forming direction of the soaker pad web material


300


. The spot connections


377




a


and


377




b


could be elongated spot connections or discontinuous seam connections or any connection type capable of limiting the movement of the pad during the bag forming process. Seams


326




a


and


326




b


also prevent the soaker pads


328


from slipping between the surfaces of the enclosure material


325


and the bag film


315


along an axis perpendicular to the forming direction of the soaker pad web material


300


. Adhesives could be utilized to create the connections at seams


326




a


,


326




b


and at spots


377




a


and


377




b


as opposed to heat sealing. Adhesives used to connect polymeric materials together are well known in the art and any known adhesive could be utilized with the present invention.




Shown in

FIG. 8A

is an alternate method of positioning the soaker pad


328


between the enclosure material


325


and the bag film


315


. This alternate method would feed the cut soaker pads


328


between two nip rollers such as


395


and


396


. Roller


395


would feed enclosure material


325


, and roller


396


feeds bag film


315


, in the same direction indicated by the arrows in

FIG. 8A

, and the soaker pads


328


would be placed between enclosure material


325


and bag film


315


at bag length intervals.




Once the soaker pad web material


300


is fully formed as described above the method of the present invention would preferably include a conventional bag making machine


390


such as the bag making machine for making bags from the soaker pad web material. The bag making machine disclosed in U.S. Pat. No. 3,678,812, which is hereby incorporated by reference, may be used as the bag making machine


390


. Bag making machine


390


for making bags would preferably include a conventional folding device generally indicated by the numeral


380


. A conventional folding device


380


such as the folding device disclosed in U.S. Pat. No. 3,678,812. Folding device


380


folds the soaker pad web material


300


into preferably “J-sheeting” as is known in the art, with a first side


312




b


longer than a second side


314




b


to form a lip


314


on each resulting bag


310


as shown in

FIGS. 10A and 10B

. It would not be necessary to fold the soaker pad web material


300


so that one side is longer than the other, but instead, both sides could be of equal length Machine


390


would include a conventional mechanism shown in U.S. Pat. No. 3,678,812 for cross sealing and cutting off soaker pad web material


300


to form a storage bag with soaker pad


310


as shown in

FIGS. 10A and 10B

. Bag making machines such as bag machine


390


are well known in the art and any such machine could be utilized as the bag machine of the present invention.




Shown in

FIG. 9

is soaker pad web material


300


comprising preferably a single continuous rectangular sheet of perforated enclosure material


325


including perforations


330


therein. However, perforated enclosure material could be formed from several pieces of material connected to each other along continuous longitudinal seams. Perforated enclosure material


325


is connected continuously adjacent to its edges


325




a


and


325




b


to bag film


315


to form seams


326




a


and


326




b


. Preferably, bag film


315


is transparent, rectangularly shaped, impervious plastic film


315


. Sandwiched between the perforated enclosure material


325


and the bag film


315


are soaker pads


328


. To prevent movement of the soaker pad


328


along a direction parallel to the enclosure material's edges


326




a


and


326




b


the enclosure material


325


is connected to the bag film at spot connections


377




a


and


377




b


on each side of soaker pad


328


. Any number of connections of the type that limit the movement of the pad


328


between the enclosure material


325


and the bag film


315


could be included if desired. A single connection such as spot connection


377




a


positioned on only one side of each soaker pad


328


may be enough to prevent movement of the pad


328


depending on the web path utilized by the actual mechanisms chosen to perform the various functions required.




The bag film


315


, perforated enclosure material


325


, and soaker pads


328


used to make bags


10


and soaker pad web material


300


of the present invention could be treated with antimicrobial agents to control of the spread of microorganism such as those specifically listed above by using the techniques previously described for treating enclosure


26


of

FIGS. 1-3

.




Referring now to
