There is a pair of interlockable fastener strips mounted on the mouth of the container with the strips being joined together at one end and separable at the other end. The gusset is unfoldable to an exterior position when the strips are separated to form a spout for pouring the contents from the interior of the container.
Another embodiment of the invention might involve a container comprising nonrigid sheet material formed to have a mouth, having first and second sides. The mouth also has first and second ends. A first fastener strip is attached to the sheet material at the first side of the mouth. The first strip has a first end and a second end with the first end of the first strip attached at the first end of the mouth. A second fastener strip is attached to the sheet material at the second side of the mouth. The second strip has a first end and a second end with a first end of the second strip attached to the first end of the mouth. The first strip and the second strip are capable of releasable connection to each other. A slider is received on the strips and is movable in a first direction toward the first end of the mouth to connect the first strip to the second strip and is movable in a second direction toward the second end of the mouth to disconnect the first strip from the second strip. The first end of the first strip is not attached to the first end of the second strip. The sheet of material forms a gusset at the first end of the mouth.
Still another embodiment of the invention involves a flexible, reclosable container having a pair of side walls forming a mouth having first and second sides. The mouth has first and second ends. A first interlockable profile is attached proximate a first side of the mouth with the first profile having a first end and a second end. The first end of the first profile is attached proximate the first end of the mouth. A second interlockable profile is attached proximate a second side of the mouth.

The present invention pertains to improved methods and apparatus for containers. In one embodiment of the present invention, there is a container of semi-rigid paper or cardboard walls which includes within it a roll of flexible film, such as the type of film used by consumers to cover an object that has food on it. The flexible film held within this container is wrapped on a roll and must be cut to the desired length by the consumer. In one embodiment of the present invention, a tracked, slidable cutter is positioned along an open edge of the container. The flexible film can be drawn out of the container by the consumer and placed over a track along one edge of the container. The consumer then moves the slidable cutter along the track, cutting the flexible film to the desired length. In some embodiments of the present invention, the slidable cutter moves along a rigid track. In another embodiment of the present invention, the slidable cutter moves along a pair of flexible interengagable strips or members. In some embodiments, the strips are fastened to each other at each end of the path of the slidable cutter. In yet other embodiments, the strips are fastened to each other at only one end, and are not fastened to each other at any other position along the length of the cutter path.
According to another embodiment of the present invention, there is a preferably flexible container, such as a stand up pouch, preferably including one or more folding gussets along one of the sides. This container includes a mouth through which a consumer can remove contents of the container, or add something to the container. A pair of interlockable fastener profiles, which can be flexible, semi-rigid or rigid, extend along the mouth. A slider is coupled to the profiles, and can be slid along the length thereof for repeated unlocking and interlocking of the profiles. In one embodiment, the profiles are fused together at one end, and are not otherwise attached to each other along their length, except for the engagement that occurs as a result of the interlocking of the profiles. The unattached end of interlockable fastener strips is positioned at the end of the container which is intended to be the opened end of the container. When the slider is moved from this unattached end toward the fused end of the interlockable fastener strips, the extent to which the mouth of the container can be opened is not limited or constrained by the fastener strips, since the fastener strips are not attached to each other.
In one embodiment of the present invention, the unattached and uncoupled ends of the fastener profile are along a side of a container that includes a folding gusset which can be folded outward to form a pouring spout. The opened width of the spout is greater than the width that could be obtained if the fastener profiles were coupled to each other at the spout end. The present invention also contemplates those embodiments which do not include any side gussets, and which are not stand up pouches.

Referring to
Operation of apparatus 130 is as follows. A consumer opens container 132 and grabs free edge 136 of supply 135 of film. Upper gripping member 144 is moved away from lower gripping member 143, and the free end 136 from the supply 135 of film is placed on top of lower gripping member 143. Upper gripping member 144 is then released such that free edge 136 is loosely sandwiched between opposing faces of the gripping members. In order to cut the film, sliding cutter 170 is moved from combined endstops 146 toward single endstop 148. As the gripping members slide within the interior of cutting element 170, internal ribs 182a and 182b press the gripping members together. The film is held in place by friction from the mating faces of the gripping members. The co-action of male mating feature 145b within female mating feature 145a increases the frictional hold of the gripping members on the film. Gripping members 143 and 144 securely hold the film as cutting element 172 cuts the film. In some embodiments of the present invention, gripping members 143 and 144 include interlockable profile elements. In these embodiments, separator 184 of cutter 70 assists in releasing the interlock of the profile members.
Preferably, container 1032 includes a pair of extended lips 1039 which extend from mouth 1034 upwardly toward a pair of interlockable fastener strips 1043 and 1044. Fastener strip 1043 includes a first interlockable profile 1045a, and second interlockable fastener strip 1044 includes a second interlockable profile 1045b. Interlockable profiles 1045a and 1045b may be of any type easily interlockable and separable. Fastener strips 1043 and 1044 are preferably joined together at combined endstop 1046 by any suitable means including fusion by ultrasonics and/or heat, adhesion and mechanical joining. In one embodiment, fastener strips 1043 and 1044 are not otherwise joined or coupled together, except at combined endstop 1046 and except as by action of a movable slider 1070. Slider 1070 is slidably coupled to fastener strips 1043 and 1044. Movement of slider 1070 in a first direction interlocks profiles 1045a and 1045b. Movement of slider 1070 in the opposite direction unlocks profiles 1045a and 1045b from each other. As shown in
In some embodiments, mouth 1034 of container 1032 includes one or more areas including a peelable seal, as shown in cross-hatch in
