Abstract
Abstract A sealing device for a zip fastener, comprising a lock having therethrough a channel, of which a wall portion is resilient and into which can be inserted the shaft of a disposable sealing member comprising a head and a shaft under temporary deformation of the resilient wall portion, and then be retained therein secured against withdrawal and rotation, while the head fixes the pulling lip of the zip fastener and the pulling lip is provided with a rotatable disc having a receiving cavity for the head of the sealing member, all this in such a manner that as a result of rotation of the disc the shaft of the sealing member can be twisted to fracture.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
204 words
In a sealing device for a fastener having a pulling lip, the sealing device including a lock; a channel extending at least into said lock, having at least a portion thereof of uncircular cross-section and including wall means; a disposable rupturable sealing member which is to be inserted into said channel, said sealing member having a head and a shaft, said shaft having at least an end portion thereof which is of uncircular cross-section and said head being fixable to the pulling lip of the fastener; and means coupled to said sealing member for twisting at least that portion of said shaft adjacent said head relative to said end portion which is to be secured against rotation in said portion of said channel of uncircular cross-section for unsealing the device, the improvement wherein said wall means of said channel include at least one resilient portion thereby to allow said end portion of said sealing member to be forced past said resilient portion, said wall means including said resilient portion defining a boundary face which constitutes stop means for said end portion of said shaft when said end portion has been inserted into said channel and rests beneath said resilient portion of said wall means.
Claim 2
Dependent Claim
204 words
In a sealing device for a fastener having a pulling lip, the sealing device including a lock; a channel extending at least into said lock, having at least a portion thereof of uncircular cross-section and including wall means; a disposable rupturable sealing member which is to be inserted into said channel, said sealing member having a head and a shaft, said shaft having at least an end portion thereof which is of uncircular cross-section and said head being fixable to the pulling lip of the fastener; and means coupled to said sealing member for twisting at least that portion of said shaft adjacent said head relative to said end portion which is to be secured against rotation in said portion of said channel of uncircular cross-section for unsealing the device, the improvement wherein said wall means of said channel include at least one resilient portion thereby to allow said end portion of said sealing member to be forced past said resilient portion, said wall means including said resilient portion defining a boundary face which constitutes stop means for said end portion of said shaft when said end portion has been inserted into said channel and rests beneath said resilient portion of said wall means.
Claim 3
Dependent Claim
39 words
An improved device according to claim 1, wherein said means for twisting comprise a disc connected to said pulling lip, and said pulling lip includes a recess for receiving and holding at least said head of said sealing member.
Claim 4
Dependent Claim
43 words
An improved device according to claim 2, wherein said shaft of said sealing member includes an intermediate portion which is of uncircular cross-section, and said pulling lip includes a recess of uncircular cross-section for receiving and holding said intermediate portion of said shaft.
Claim 5
Dependent Claim
58 words
An improved device according to claim 1, wherein said shaft of said sealing member includes an intermediate portion which is of uncircular cross-section, and wherein said means for twisting comprises a disc provided with a cavity for receiving said head of said sealing member and an opening for passing said intermediate portion of said shaft secured against rotation.
Claim 6
Dependent Claim
37 words
An improved device according to claim 1, wherein said channel extends through said lock, whereby said end portion of said shaft and possibly part of said shaft may fall from the lock when the device is unsealed.
Claim 7
Dependent Claim
42 words
An improved device according to claim 1, wherein said lock comprises two plate-shaped elements and the device further comprises snap-on connection means for permanently coupling said plate-shaped elements together and to material of an article of which the fastener constitutes a part.
Claim 8
Dependent Claim
27 words
An improved device according to claim 1, wherein said fastener is a zip fastener, and including a transportation bag connected to said zip fastener and closeable thereby.
Claim 9
Dependent Claim
18 words
An improved device according to claim 1, wherein said sealing member is made entirely of substantially nonresilient, material.
