Abstract
Abstract A simple and quickly appliable bag closure device which automatically tightens the neck of the bag. According to a preferred embodiment of the invention the device comprises a label holder in the form of a generally flattened base and a cover for closure over the base. Said base and cover are provided with means permitting them to be sealed in the closed position by means of a security seal. The base is centrally formed with a cavity shaped to receive a lever which is a separate part of the label holder although connected thereto by a string fixed at one end to one of various points along the length of the lever and at the other end to a label. The lever is formed, with relation to the cavity, so that it may be pivoted about one end to apply an automatic tightening to the neck of the bag about which the lever is passed before being placed in the cavity. The closure of the cover over the base also closes the lever in the cavity.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
226 words
A device for closing bags comprising: (a) a lever provided with means for fixing one end of a string or the like to at least one point along its length and a guide for the string or the like at a fixed point on the lever which is spaced from a first end thereof; (b) an element defining an open topped elongated cavity for the lever and having means for fixing the other end of the string or the like to at least one point thereof, said element being provided with string guide means disposed substantially axially with respect to the cavity and a support in said cavity for said first end of the lever so that, on placing the lever within the cavity, the contact point between said first end and the support lies between the guide on the lever and the guide means on said element, defining approximately a straight line; and (c) a closure member for closing said top of the cavity with the lever therein, said closure member and said element being provided with means permitting their immobilization with respect to each other by the application of a security seal, said string fixing means on at least one of said element and lever defining a plurality of fixing points to permit the adjustment of the length of the string or the like.
Claim 2
Independent Claim
226 words
A device for closing bags comprising: (a) a lever provided with means for fixing one end of a string or the like to at least one point along its length and a guide for the string or the like at a fixed point on the lever which is spaced from a first end thereof; (b) an element defining an open topped elongated cavity for the lever and having means for fixing the other end of the string or the like to at least one point thereof, said element being provided with string guide means disposed substantially axially with respect to the cavity and a support in said cavity for said first end of the lever so that, on placing the lever within the cavity, the contact point between said first end and the support lies between the guide on the lever and the guide means on said element, defining approximately a straight line; and (c) a closure member for closing said top of the cavity with the lever therein, said closure member and said element being provided with means permitting their immobilization with respect to each other by the application of a security seal, said string fixing means on at least one of said element and lever defining a plurality of fixing points to permit the adjustment of the length of the string or the like.
Claim 3
Dependent Claim
46 words
Device according to claim 1 in which said plurality of fixing points permitting the adjustment of the length of said string means, are distributed along part of the length of said lever on its lower side between said guide and said second end of the lever.
Claim 4
Dependent Claim
30 words
Device according to claim 2 in which the upper side of said lever also has fixing points for the string means, distributed therealong between said guide and said second end.
Claim 5
Dependent Claim
36 words
Device according to claim 3 in which said fixing means on the lever comprises a series of pin means distributed along the upper and lower sides of said lever between said guide and said second end.
Claim 6
Dependent Claim
42 words
Device according to claim 4 in which said first end of the lever comprises two spaced generally rounded wall parts defining therebetween a space aligned with a slot through said support in the cavity, said slot permitting passage of said string means.
Claim 7
Dependent Claim
18 words
Device according to claim 5 characterized in that said guide on said lever comprises an orifice formed therethrough.
Claim 8
Dependent Claim
35 words
Device according to claim 1 in which said cavity defining element and said closure member are integral with each other, said closure member being adapted for being bent over said element for closing the cavity.
Claim 9
Dependent Claim
46 words
Device according to claim 7 in which said element and cover comprise a generally planar base and a cover of a label holder so that when said lever lies within said cavity, a label may be placed on the base before closure of said cover. .Iadd.
Claim 10
Dependent Claim
196 words
A device for the closure and sealing of bags or the like, comprising, a base member, a lever associated with said base member to provide a fulcrum therebetween, first attachment means for fixing one end of a length of string or the like to a point which is stationary relative to the fulcrum, second attachment means for attaching the other end of the string or the like on said lever at a point which is spaced from the fulcrum, means permitting adjustment of the effective length of said string, said string when engaged with said attachment means forming a loop which is engageable about a bag, said lever being rotatably movable about the fulcrum to tighten the string around a bag until the lever arrives at a closed position, means for making both said first and second string attachment means substantially inaccessible at least when said lever is in said closed position, and means permitting said device to be sealed by a security seal when the lever is in said closed position..Iaddend. .Iadd.10. A device according to claim 9 wherein the base member and the means for making the string attachment means inaccessible are shaped to
Claim 11
Dependent Claim
194 words
hold a flat label therebetween..Iaddend. .Iadd.11. A device for closing bags, comprising a lever means including a fulcrum portion, first string fixing means for fixing a first end of a string or the like to the lever means, an element defining a space for receiving the lever means, the element having a second string fixing means for fixing a second end of the string thereto, said element having support means cooperable with said fulcrum portion of said lever means so that said lever means is rotatable about its fulcrum to a final position within said space to draw said first end of said string into said space; and a closure member for closing the space when the lever is therein, to define a closed configuration wherein said closure member, said element, and said lever means may be relatively immobilized by the application of a security seal, one of said string fixing means providing a plurality of string fixing points to permit adjustment of the effective length of the string or the like..Iaddend. .Iadd.12. A device according to claim 11 wherein the element and the closure member are shaped to hold a flat label therebetween..Iaddend.
