Definitions
- the present invention relates to reclosable bag. More particularly this invention concerns such a bag that can be used to hold bulk material.
- a typical bag such as used to hold bulk material like seed, foodstuff, food ingredients, dry dog food, or cat litter, has two similar flexible face panels each having a pair of generally parallel side edges and upper and lower edges bridging upper and lower ends of the side edges. The lower edges can be joined together to close the bottom of the bag after it is filled.
- a pair of gussets each have a crease and two generally parallel side edges flanking the crease, one of the side edges of each gusset being joined to the side edge of one of the panels and the other of the gusset side edges being joined to the side edge of the other panel.
- a reclosable fastener extends along the upper edges at the face panels.
- Such a side gusset bag is known from DE 20 20076 002 916 U1. Its fastener is closable and openable by a slider mounted on the upper edge of the bag and extends over the entire width of the bag.
- the side gussets terminate below the reclosable fastener and are each closed by a sealable closable film that is attached to the inside of the front panel of the bag and covers the open end of the side gusset. Opening the reclosable fastener creates a large pouring opening. This makes controlled delivery of bulk material difficult.
- a side gusset bag known from DE 10 2006 029 119 A1 closed at the upper edge of the bag by an upper sealing seam and has a reclosable fastener below the upper weld in the region of the side gusset.
- the reclosable fastener is a closure strip that is attached to the inner surface of a side gusset and to sections of the two face panels. A segment of the bag above the reclosable fastener must be detached in order to open the bag. As a result, the reclosable fastener is exposed in the region of the side gusset.
- the side gusset can be unfolded as a spout and is reclosable.
- a bag known from US 2007/0230834 A1 comprises an upper reclosable fastener that extends over approximately half the width of the bag starting from one longitudinal edge of the bag.
- the reclosable fastener is mounted on the inner surfaces of the face panels of the bag below the upper weld. A section of the bag above the reclosable fastener must be detached when the bag is opened for the first time.
- the bag can also be designed as a side gusset bag.
- U.S. Pat. No. 3,326,449 relates to a side gusset bag where the upper bag edge closed by a weld is stepped.
- the stepped edge borders a central two-layer region of the bag in which the face panels of the side gusset bag are directly attached by welds. Bordering this region on the right and left are four-layer edge regions each of which is composed of a segment of the two face panels and one inserted side gusset.
- the center two-layer bag region must be separated to open the bag. It is not possible to reclose the bag.
- Another object is the provision of such an improved reclosable gusset bag that overcomes the above-given disadvantages, in particular that enables bulk material to be effectively poured out in controlled fashion poured and where the pouring opening of the bag is reclosable.
- the filled bag packaging according to the invention should also be of rectangular shape and stackable.
- a bag that is normally manufactured and transported flat and then filled and sealed has according to the invention two similar and flexible face panels each having a pair of generally parallel side edges and upper and lower edges bridging upper and lower ends of the side edges.
- a pair of gussets each have a crease and two generally parallel side edges flanking the crease, one of the side edges of each gusset being joined to the side edge of one of the panels and the other of the respective side edges to one of the side edges of the other panel.
- the face panels both have extensions extending upward past at least one of the gussets and of a horizontal width measured perpendicular to the side edges that is substantially less than a width of the face panels perpendicular to the side edges at the level of the gussets.
- a reclosable fastener extends along the upper edges only at the extensions and forms therewith a spout that can be folded over and juxtaposed with one of the face panels.
- the spout can be releasably secured to the one face when folded over the one face panel.
- This side gusset bag according to the invention is intended, in particular, for packaging lumpy, granular, and pourable bulk material.
- the face panels can be attached directly to each other along their upper edges by welds except at the reclosable fastener. This results in a pouring spout equipped with a reclosable fastener, where the length and width of the spout can be adjusted for the bulk material.
- the pouring spout enables material to be discharged very precisely and ensures accurate placement when the bulk material is poured out into, for example containers provided for this purpose. Due to the reclosable fastener, the bulk material stays fresh and no odors escape.
- the reclosable fastener also prevents spilling or infestation caused by the entry of moisture, animals, or pests.
- the pouring spout formed by two film layers can be easily folded and is held by the releasable attachment on the front face of the front panel of the side gusset bag. As a result, the filled package is rectangular so that can be stacked neatly.
- the pouring spout is preferably at the center of the bag.
- the face panels of the bag can be of trapezoidal shape in the upper region, or form a surface bordered by arcuate edges and is narrower at the spout than in the base region.
- the flow of product toward the pouring spout can be further improved if corner welds are provided at the upper ends of the side gussets. These welds or seams attach the flaps of the side gusset to the adjacent face panels, and, starting from the edge of the bag, extend at an acute angle to the upper edge of the side gussets. As a result of these welds, the cross-section of the bag tapers down in a funnel shape toward the pouring spout.
- Handling of the side gusset bag according to the invention can be further improved by attaching a grip.
- Die-cut holes for finger or hand access as well as a handle can form the grip.

Abstract
A bag has two flexible face panels and a pair of gussets each having a crease and two generally parallel side edges flanking the crease and joined to side edge of the panels. The face panels both have extensions extending upward past at least one of the gussets and of a horizontal width measured perpendicular to the side edges that is substantially less than a width of the face panels perpendicular to the side edges. A reclosable fastener extends along the upper edges only at the extensions and forms therewith a spout that can be folded over and juxtaposed with one of the face panels. The spout can be releasably secured to the one face when folded over the one face panel. This side gusset bag is intended, in particular, for packaging lumpy, granular, and pourable bulk material.
Description
- The present invention relates to reclosable bag. More particularly this invention concerns such a bag that can be used to hold bulk material.
- A typical bag, such as used to hold bulk material like seed, foodstuff, food ingredients, dry dog food, or cat litter, has two similar flexible face panels each having a pair of generally parallel side edges and upper and lower edges bridging upper and lower ends of the side edges. The lower edges can be joined together to close the bottom of the bag after it is filled. A pair of gussets each have a crease and two generally parallel side edges flanking the crease, one of the side edges of each gusset being joined to the side edge of one of the panels and the other of the gusset side edges being joined to the side edge of the other panel. A reclosable fastener extends along the upper edges at the face panels.
- Such a side gusset bag is known from DE 20 20076 002 916 U1. Its fastener is closable and openable by a slider mounted on the upper edge of the bag and extends over the entire width of the bag. The side gussets terminate below the reclosable fastener and are each closed by a sealable closable film that is attached to the inside of the front panel of the bag and covers the open end of the side gusset. Opening the reclosable fastener creates a large pouring opening. This makes controlled delivery of bulk material difficult.
- A side gusset bag known from DE 10 2006 029 119 A1 closed at the upper edge of the bag by an upper sealing seam and has a reclosable fastener below the upper weld in the region of the side gusset. The reclosable fastener is a closure strip that is attached to the inner surface of a side gusset and to sections of the two face panels. A segment of the bag above the reclosable fastener must be detached in order to open the bag. As a result, the reclosable fastener is exposed in the region of the side gusset. The side gusset can be unfolded as a spout and is reclosable.
- A bag known from US 2007/0230834 A1 comprises an upper reclosable fastener that extends over approximately half the width of the bag starting from one longitudinal edge of the bag. The reclosable fastener is mounted on the inner surfaces of the face panels of the bag below the upper weld. A section of the bag above the reclosable fastener must be detached when the bag is opened for the first time. The bag can also be designed as a side gusset bag.
- U.S. Pat. No. 3,326,449 relates to a side gusset bag where the upper bag edge closed by a weld is stepped. The stepped edge borders a central two-layer region of the bag in which the face panels of the side gusset bag are directly attached by welds. Bordering this region on the right and left are four-layer edge regions each of which is composed of a segment of the two face panels and one inserted side gusset. The center two-layer bag region must be separated to open the bag. It is not possible to reclose the bag.
- It is therefore an object of the present invention to provide an improved reclosable gusset bag.
- Another object is the provision of such an improved reclosable gusset bag that overcomes the above-given disadvantages, in particular that enables bulk material to be effectively poured out in controlled fashion poured and where the pouring opening of the bag is reclosable.
- The filled bag packaging according to the invention should also be of rectangular shape and stackable.
- A bag that is normally manufactured and transported flat and then filled and sealed has according to the invention two similar and flexible face panels each having a pair of generally parallel side edges and upper and lower edges bridging upper and lower ends of the side edges. A pair of gussets each have a crease and two generally parallel side edges flanking the crease, one of the side edges of each gusset being joined to the side edge of one of the panels and the other of the respective side edges to one of the side edges of the other panel. The face panels both have extensions extending upward past at least one of the gussets and of a horizontal width measured perpendicular to the side edges that is substantially less than a width of the face panels perpendicular to the side edges at the level of the gussets. A reclosable fastener extends along the upper edges only at the extensions and forms therewith a spout that can be folded over and juxtaposed with one of the face panels. The spout can be releasably secured to the one face when folded over the one face panel. This side gusset bag according to the invention is intended, in particular, for packaging lumpy, granular, and pourable bulk material.
- The face panels can be attached directly to each other along their upper edges by welds except at the reclosable fastener. This results in a pouring spout equipped with a reclosable fastener, where the length and width of the spout can be adjusted for the bulk material. The pouring spout enables material to be discharged very precisely and ensures accurate placement when the bulk material is poured out into, for example containers provided for this purpose. Due to the reclosable fastener, the bulk material stays fresh and no odors escape. The reclosable fastener also prevents spilling or infestation caused by the entry of moisture, animals, or pests. The pouring spout formed by two film layers can be easily folded and is held by the releasable attachment on the front face of the front panel of the side gusset bag. As a result, the filled package is rectangular so that can be stacked neatly.
- The pouring spout is preferably at the center of the bag. The face panels of the bag can be of trapezoidal shape in the upper region, or form a surface bordered by arcuate edges and is narrower at the spout than in the base region.
- The flow of product toward the pouring spout can be further improved if corner welds are provided at the upper ends of the side gussets. These welds or seams attach the flaps of the side gusset to the adjacent face panels, and, starting from the edge of the bag, extend at an acute angle to the upper edge of the side gussets. As a result of these welds, the cross-section of the bag tapers down in a funnel shape toward the pouring spout.
- Handling of the side gusset bag according to the invention can be further improved by attaching a grip. Die-cut holes for finger or hand access as well as a handle can form the grip. The grip can in particular be made of film, molded components, the material of the face panels or gussets. The handle can be applied to the outer face of the bag, or be attached to the inside of the bag and extend out through a die-cut pattern or hole. In the above-described implementation, the grip is advantageously on one of the face panels. The grip can also be provided on one of the side gussets. If the pour spout is offset inward from one of the side gussets, the grip is on the other side gusset. The pouring spout formed from the face panels of the bag can also be disposed off-center relative to the bag. It is within the scope of the invention for the face panels to extend continuously along a first longitudinal side of the bag up to the upper end of the bag, and for the face panels, which are narrower in the upper region of the bag than in the region of the inserted side gussets, to have an edge that extends continuously or arcuately up to the second longitudinal side of the bag. A grip can be provided on the side gusset and fitted into the longitudinal side of the bag between the face panels to improve handling.
- The reclosable fastener provided on the pouring spout can be a press- or slide-type closure. In the case of a press-type, the strip-shaped locking elements are joinable manually by being pressed together. In the case of a slide-type closure, a slider is provided that can move along the strip-shaped elements.
- The reclosable fastener is attached to the pouring spout formed by the two face panels. It can be mounted on the end of the pouring spout in such a way that the slider is freely accessible. However, it is also within the scope of the invention for the reclosable fastener to be recessed in the two-layer upper region, formed by the two face panels, at a certain distance from the upper edge of the pouring spout. The reclosable fastener is accordingly wholly or partially covered by the face panels and hence protected from damage or tampering. If the reclosable fastener is covered by the face panels, the pouring spout can be closed at its free end by an upper weld. Detaching a segment of the bag above the reclosable fastener enables the reclosable pouring opening to be exposed. The slider of the slide-type fastener is preferably completely exposed by detaching the segment of the bag above the fastener.
- Since the pouring spout is composed of only two film layers, it is readily foldable and after being appropriately folded over rests against the front panel of the side gusset bag. A strap with an adhesive surface is preferably connected to the pouring spout for releasable attachment to the front panel of the bag. However, another possible approach is to releasably affix the folded-over pouring spout to the front panel of the bag by means of an adhesive, for example in the form of a hot-melt adhesive spot.
- The side gusset bag is produced as a flat-laid bag and is subsequently filled in filling systems with bulk material that is preferably introduced through a bottom or side opening. After being filled, the initially open end of the bag is sealed by a base weld. Corner welds can be provided at the bottom end of the bag to restrict the filling opening, which seams attach the flaps of the side gussets to the face panels of the bag.
- The side gusset bag is advantageously equipped with a flexible grip, in particular, when the side gusset bag has a large fill volume or high bulk density, the grip being on a front wall or in the region of the side gusset or in the base region. The grip can be a flexible strip made of a film or a, for example of a fabric-reinforced laminate. The grip can furthermore be composed of a flexible strip and a cover film, the cover film being fixed to the inside of the bag and the strip extending as a loop out through the opening of the bag panel.
- The above and other objects, features, and advantages will become more readily apparent from the following description, reference being made to the accompanying drawing in which:
-
FIG. 1 is a perspective view of a closed bag according to the invention; -
FIGS. 2 a and 2 b are front elevational views of the bag ofFIG. 1 in use and storage positions; and -
FIG. 3 is a view likeFIG. 2 b showing an alternative bag in the storage position. - As seen in
FIG. 1 abag 1 according to the invention for lumpy, granular or powdered bulk material, has an essentially parallepipedal shape and is stackable when fill. The composed of thebag 1 is filled from the bottom and is then sealed at the bottom by a base weld 2. The following discussion describes the features of thebag 1 in more detail based onFIGS. 2 a and 2 b. - The
bag 1 comprises twoface panels 3 that form front and back walls,side gussets reclosable fastener 5 that has matable strips 6 for attachment to the inside faces of thebag 1. Thegussets fastener 5 that is in a two-layer upper region of the bag formed only from the is twopanels 3. Thepanels 3 are of a smaller width in the upper region than in the region of thegussets spout 8 that is can be folded over against thefront face panel 3. - In the position shown in
FIG. 2 a, thespout 8 allows for a very precise controlled discharge during pouring and ensures good placement accuracy when the purpose of pouring is, for example, to fill a bowl or a small container. For transport purposes and after pouring has ended, thespout 8 can be applied to thefront panel 3 of the side gusset bag and affixed there, as shown inFIGS. 1 and 2 b. As a result, the filled bag can be easily transported. Due to the fact that thespout 8 is attached to thefront panel 3, the rectangular shape is maintained such that stackability of the packaging is not impaired by thespout 8. - In the embodiment shown in
FIGS. 1 , 2 a and 2 b, thespout 8 is at the center of the bag. Thepanels 3 here form a surface bordered by arcuate connectingedges 9, this surface being narrower at thespout 8 in the rectangular base region. A trapezoidal shape for the face panels in the upper region is also possible. A width B of the pouring spout at the pouring end depends on the product inside thebag 1. Its width can measure, for example, 25% to 75% of a total width B0 of the bag. - The
fastener 5 is a slide-type closure and has aslider 10 that can shift along the strips 6. Thefastener 5 is here mounted the outer end of thespout 8 such that theslider 10 is freely accessible. Additionally, a recessed mounting is possible. - A tab or
strap 11 with an adhesive patch is provided for the releasable attachment of thespout 8 to thepanel 3 of thebag 1. It is also within the scope of the invention for the folded-overspout 8 to be fixed tofront panel 3 of the bag by an releasable adhesive. - A
grip 12 is on the onefront panel 3 of thebag 1 to make the package easier to handle. Thisgrip 12 can be a flexible strip that is attached to the front wall. One preferred type of attachment is illustrated inFIGS. 2 a and 2 b. Thegrip 12 is composed here of aflexible strip 13 and acover film 14, the latter being attached to the inner face of the bag so thestrip 13 can project as a loop anopening 15 in thefront bag panel 3. -
FIGS. 2 a and 2 b show corner welds 16 provided at the upper ends of theside gussets welds 16 attach the flaps of thegussets respective panels 3 and extend at an acute angle from the edge of the bag to the upper edge of the side gussets. The corner welds 16 allow the flow of product within the packaging to be controlled. Abottom end 17 of the flat-laid side gusset bags is open to allow them to be filled. To enable the filling opening to be restricted, corner welds 18 are also provided at thebottom end 17 of the bag. Thesewelds 18 also attach the flaps of the isgussets panels 3. - In the embodiment of
