BACKGROUND OF THE INVENTION

Field of the Invention

This application generally relates to closure strips, and in particular, closure strips attached to sidewalls of an opened bag to convert the bag from non-reclosable to reclosable.

Description of the Related Art

Bags that can be reclosed after being opened frequently include ziplock closures having complementary profile strips. Such closures can be connected to one another by pressing together the strips and separated by pulling apart the strips. Alternatively, a slider is attached onto the closure and encompasses the profile strips. Slider closures may be opened or closed, by displacing the slider along the strips. However, typical bags produced for food items, such as snacks and cereal are often not resealable or produced with such closures. As a result, the food items easily go stale and gets wasted etc. Existing solutions such as using clips are only partially effective because clips break or get lost and do not effectively seal an opening of a bag but rather, hold the opening closed.

SUMMARY OF THE INVENTION

The present invention provides a pair of closure strips for resealing bags. The pair of closure strips comprises a first closure strip comprising a substrate including a grip strip, a groove strip, and an adhesive region, the groove strip. The pair of closure strips further comprises a second closure strip comprising a substrate including a grip strip, a stem strip, and an adhesive region. The stem strip comprises a stem structure that interlocks with a groove of the groove strip. The first closure strip and the second closure strip being discrete elements from a bag and are attached to the bag by adhering the adhesive region of the first closure strip and the adhesive region of the second closure strip to sidewall regions adjacent to an opening of the bag.
The groove strip is on an inner-facing side of the first closure strip and the stem strip is on an inner-facing side of the second closure strip. Each of the first closure strip and the second closure strip may further comprise a grip strip. The grip strip may provide improved ease of holding a top section of the closure strip. The grip strip may comprise a plurality of elongated generally parallel ridges spaced apart in parallel relationship and horizontally extending from substantially a first edge of the closure strip to a second edge of the closure strip.
The substrates of the first closure strip and the second closure strip may comprise a sheet material including paper or plastic film. The first closure strip and the first closure strip may be pre-attached and wound into a spool. The first closure strip and the first closure strip may be perforated at set lengths.

It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. Likewise, a reasonably broad scope for claimed or covered subject matter is intended. Throughout the specification and claims, terms may have nuanced meanings suggested or implied in context beyond an explicitly stated meaning. Likewise, the phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment and the phrase “in another embodiment” as used herein does not necessarily refer to a different embodiment. It is intended, for example, that claimed subject matter include combinations of exemplary embodiments in whole or in part. The following detailed description is, therefore, not intended to be taken in a limiting sense.
The present application discloses closure strips for resealing bags not originally equipped with closure means. The disclosed closure strips may comprise a pair of complementary adhesive closure strips that may be used as an aid or accessory for bags. In particular, the adhesive closure strips are separate elements and do not form an enclosure or bag themselves whether in combination or alone. The complementary adhesive closure strips may include a slot and groove (e.g., ziplock) mechanism such that the complementary adhesive closure strips forms a seal when pressed together. Each of the complementary adhesive closure strips may be adhered to a region of a given inner or outer sidewall adjacent to an opening of a bag thereby creating a closure by coupling the slot and groove mechanism to the bag.
FIGS. 1 and 2 present a pair of complementary adhesive closure strips according to an embodiment of the present invention. Closure strip 102 comprises a substrate including a grip strip 104, a groove strip 106, and an adhesive region 108. The substrate as well as any other portion of the closure strip 102 can be constructed from any material, such as paper or plastic film (e.g., polyethylene polymers). Grip strip 104 may provide for improved ease of opening and holding of the closure strip 102 along a top section of the closure strip 102 when attached to an existing container, such as a bag. The grip strip 104 comprises a plurality of elongated generally parallel ridges spaced apart in parallel relationship and horizontally extending from substantially one edge of the closure strip 102 to the other edge of the closure strip 102.
Closure strip 102 has an inner-facing side and an outer-facing side. Groove strip 106 is located in a midsection region of closure strip 102 below the grip strip 104 and above the adhesive region 108. Groove strip 106 is situated on the inner-facing side and comprises a complementary groove or cavity adapted to be pressed together into interlocking relation with a stem component (stem strip 206) on the inner-facing side of closure strip 202. As such, closure strip 102 may form a seal with closure strip 202. Closure strip 102 may be separated from closure strip 202 by pulling them apart.
Adhesive region 108 enables the closure strip 102 to be attached to a container surface. The adhesive region 108 comprises a section located at a bottom portion of the closure strip 102 that can be adhered to an inner or outer sidewall of an existing container along an opening of the existing container. The adhesive region 108 may exist on the inner-facing side of the closure strip 102 for application to an outer sidewall of an existing container. Alternatively, the adhesive region 108 may exist on the outer-facing side of the closure strip 102 for application to an inner sidewall of an existing container. To protect the adhesive region 108 and permit handling without the adhesive region 108 catching on any environmental surface until it is intended to apply the closure strip 102 to a container, the adhesive region 108 may include a protective sheet that is applied in covering relation to the adhesive region 108 but is able to be peeled therefrom and removed prior to adhering to the container.
Closure strip 202 comprises a companion strip to closure strip 102. Closure strip 202 comprises a substrate including a grip strip 204, a stem strip 206, and an adhesive region 208. The substrate as well as any other portion of the closure strip 202 can be constructed from any material, such as paper or plastic film (e.g., polyethylene polymers). Grip strip 204 and adhesive region 208 may include structure and functionality that are identical to grip strip 104 and adhesive region 218, respectively. That is, closure strip 202 mirrors the structures of closure strip 102 with the exception of the stem strip 206.
Closure strip 202 also includes an inner-facing side and an outer-facing side. Stem strip 206 is situated on the inner-facing side and comprises a stem structure adapted to be pressed together into interlocking relation with a groove component (groove strip 106) on the inner-facing side of closure strip 102. Stem strip 206 is located in a midsection region of closure strip 202 below the grip strip 204 and adhesive region 108. Particularly, stem strip 206 is located in a substantially similar location as groove strip 106 in relation to the midsection region of closure strip 102 such that stem strip 206 is horizontally aligned with the center of the groove of the groove strip 106. According to another embodiment closure strip 102 and closure strip 202 may include any kind of locking mechanism in place of groove strip 106 and stem strip 206.
Closure strip 102 and closure strip 202 may be pre-attached to one another, wound into a spool, and thereafter be dispensed. The closure strips may be cut to a desired length and applied to individual bags. For example, the desired length may be the width of a bag or an opening of the bag. The closure strips may also be perforated at set lengths, or can come in precut strips of various lengths.
FIGS. 3A and 3B present an application of a pair of complementary adhesive closure strips to a bag according to an embodiment of the present invention.
Closure strip 102 and closure strip 202 comprise individual elements and do not form an enclosure or bag themselves whether attached or detached from one another. The closure strip 102 and closure strip 202 may be attached to a bag 300. A bag 300 may comprise any non-rigid container made from any material such as paper, plastic, organic or synthetic fibers, etc. The bag 300 includes an opening 302 to the internal cavity 304 of the bag 300.
Closure strip 102 can be adhered to an upper region of a first sidewall along opening 302 and closure strip 202 can be adhered to an upper region of a second sidewall (opposite of the first sidewall) adjacent to and along the opening of the bag. The closure strips 102 and 202 may be attached along the sidewalls adjacent to the opening 302 such that at least a portion of the adhesive regions 108 and 208 are below the opening 302 and groove strip 106 and stem strip 206 are above the opening 302. Groove strip 106 and stem strip 206 provides an easily openable and reclosable/resealable closure for the opening 302. Closure strips 102 and 202 may be pulled apart at grip strips 104 and 204 to detach groove strip 106 from stem strip 206.
FIG. 4 presents a side view of an application of a pair of complementary adhesive closure strips to an exterior of a bag according to an embodiment of the present invention.
