Description
t~`. 13257~ 0 The present invention, in one embodiment, relates to seals of the type which may be used for closing flexible containers such as mail bags. This invention also relates, in another embodiment, to seals which may 5 be used for locking other types of containers such as tote boxes for jewelry, zipper openings in flexible bags such as are used for carrying payrolls, cash drawers in bank vaults, etc.
More particularly, one embodiment of this invention relates to a seal which can close the open mouth or neck of a bag, and in one particularly preferred embodiment, provides means for attachment of identification or destination labels to the seal itself.
In another embodiment, a seal is provided which can be used for locking other types of containers such as those mentioned above and in which the seal has an adjustable feature.
Typical of seals used for closing bags are illustrated in U.S. 3,371,949 (March 5, 1968); 2,77~,909 2Q ~December 4, 1956); 2,669,476 (February 16, 1954);
More particularly, one embodiment of this invention relates to a seal which can close the open mouth or neck of a bag, and in one particularly preferred embodiment, provides means for attachment of identification or destination labels to the seal itself.
In another embodiment, a seal is provided which can be used for locking other types of containers such as those mentioned above and in which the seal has an adjustable feature.
Typical of seals used for closing bags are illustrated in U.S. 3,371,949 (March 5, 1968); 2,77~,909 2Q ~December 4, 1956); 2,669,476 (February 16, 1954);
2,983,539 (May 9, 1961). All of these seals, however, re~uire the use of a plurality of separate parts for closing the bag. Thus, the bag encircling member is usually in the form of a rope or cord; a separate piece for gripping the neck of the bag is provid~d; and still further a deformable sealing element, usually of metal, holds the rope or cord about the neck of the bag. In addition, it is necessary to have a separate tool for deformation of the sealing element once the structure has been placed around a bag to be closed.

132~710 The prior art also discloses various types of seals suitable for closing other types of containers. For example, UOS. Patent 3,290,080 (December 6, 1966) is a "padlock" type seal in which a shaft is inserted into the body of the seal. A series of barbs provided on the shaft engage with a cooperating configuration inside the body of the seal.
U.S. Patent 4,059,300 (November 22, 1977) employs a latch which is inserted into a housing for engagement with fingers therein.
U.S. Patent 4,~29,031 (October 21, 1980) and U.S.
Patent 3,46~,077 (September 9, 1969) also have a similar structure where a latch engages fingers inside a housing.
These types of seals are generally used for locking truck containers, freight cars, etc.
British Application 2,115,35~ published September 7, 1983, illustrates a type of security seal for locking a zip fastener in postal envelopes.
Typical of seals currently used for locking, e.g., cash drawers, are padlock type seals ("Chicago" locks).
None of the above prior art seals, however, provide any adjustability; in other words, the seals are only in a locked state at a certain point when the latch has been appropriately positioned to mate with its cooperating component. In addition, some types of padlock seals currently in use require a key to open the lock. This obviously causes problems in that keys are easily lost; in addition, these types of locks are very e~pensive.

A plurality of deflectors are provided in the socket member, the deflectors extending into the passageway, and adapted to deflect any tool which may be used in trying to disengage the deflectable fingers from the engagement members .
In accordance with yet another embodiment of the present invention there is provided a seal for providing a security closure, comprising: a ~ocket member having first and second open ends communicating with a passageway through the socket member, and at least one locking means within the passageway spaced from both the first and second open ends, the locking means comprising at least two deflectable fingers extending in opposition from opposite wall~ of the passageway into the passageway; a latch member integral with the socket member and comprising a first flexible extension member extending laterally from the 2n socket member, and a second flexible extension member for insertion into the first end of the socket member, the second extension member extending from the first extension member and having opposed surfaces, at least one engagement member on each of the opposed surfaces for engagement by the deflectable fingers, each the engagement member comprising a shoulder defined by a tapered recess in the vpposed surfaces and having a flat engagement surface facing toward the socket member, whereby when the second extension member is inserted into the first end of the socket member, engagement occurs between the locking means and the engagement member.

In a preferred form of the flexible container seal, the first extension member includes gripping and engaging means which take the form of a plurality of spaced-apart projections extending from the first flexible extension member. Generally, it is desirable to provide such projections with relatively pointed ends so as to enable a good gripping action around tha neck of a bag or flexible container. Also, the first flexible extension member may be of a thicker construction so that a thicker central strip is provided on the surface opposed to that from which the projections extend so as to improve the strength thareof. As such, a central strip of a greater thickness may be provided along the length of the first flexible extension member.
In the flexible contain~r seal, it is also preferred that a plurality of socket engaging members be provided on the second extension member so that the seal is adjustable to different sizes about the neck of a flexible container. Thus, upon insertion into tha socket member, the socket engaging members progressively engage the cooperating loc~ing means to thereby permit the required adjustment.
In a preferred form of the seals of the invention, the length of the first extPnsion member and the socket member are such that upon insertion of the second extension member into the first end of the socket member, the last one of the socket engaging members to enter the -.~
, : ,-,' , ~ 132~ 0 - 6c -socket member cannot exit the second end of the socket member.
In preferred embodiments of the seal, a preferred feature is that of the provision of a third flexible extension member extending from the second extension member. This extension member is integrally attached to the second extension member and is useful in guiding the second extension member into the socket and to pull it 10therethrough. In a particularly preferred form, the third extension member takes the form of label retaining means.
The label retaining means of the third flexible extension member preferably takes the form of a strap member having an aperture at one end and an enlarged head at the other end. In use, the enlarged head is moved towards the aperture at the other end, creating a circular outline for retaining a label attached to the seal. The enlarged head has shoulders which seat on the outer periphery of the aperture, thus holding th~ head in the 20aperture. Small sloks may be provided at opposed sides of the aperture so as to aid in insertion of the enlarged head therethrough.
The seals can be formed of any suitable plastic material such as polyolefins, e.g. polyethylene, polypropylene, copolymers of these materials, and the like.
While the first extension member requires flexibility, it may also be possible that the second and third extension members be formed of a relatively more rigid material, although for ease of construction and use, 30it is preferred that the whole seal be formed of the same material.

It will be appreciated that the seal can be appropriately sized for the particular application. Any number of socket engaging members can be provided depending on the desired degree of versatility and adjustability. In a preferred form, from 3 to 15 socket engaging members are provided to give a relatively large degree of adjustability; however, the seal would also be adjustable with 2 socket engaging members and in some cases, it may be desired to have more than 15 socket engaging members.
The lengths of the various sections of the latch member will also depend on the particular application.
In one form, the length of the first extension member is such that upon insertion of the second extension member into the socket, the last one of the socket en~aging members to enter the socket cannot exit the second end thereof.
Having thus generally described the invention, reference will now be made to the accompanying drawings, illustrated preferred embodiments of the invention, and in which:
FIGURE 1 is a side e]evational view of a seal according to one embodiment of the present invention;
FIGURE 2 is a bottom view of a seal;
FIGURE 3 is a side elevational view of a seal in a locked position;
FIGURE 4 is a view similar to Figure 3 with parts broken away.
FIGURES 5 and 6 are perspective views of another 3~ embodiment of the present invention; and ', , , :'~ ' , `` 132~71~
FIGURE 7 illustrates a socke-t member in accordance with Figures 5 and 60 In greater detail, a one-piece seal for closing flexible containers according to an embodiment of the present invention comprises a socket 10 of a cylindrical or tubular configuration. Socket 10 has opposed open ends 12 and 14 communicating with a passage 16 extending through socket 10. As illustrated, open end 12 of socket 10 has a smaller opening than opposed open end 14. Thus opposed inner walls 18 and 20 form a substantially rectangularly shaped opening of reduced size in end 12 of socket 10. Located within socket 10, and extending from walls 18 and 20 is a pair of opposed, spaced apart7 resilient fingers 22 and 24. As seen from Figure 1, fingers 22 and 24 extend toward open end 14 and are directed inwardly somewhat leaving a space between the fingers of reduced size relative to the size of the remainder of passageway 16. Fingers 22 and 24 are relatively resilient in that they can be urged further apart, however, upon release of any tension thereon, fingers 22 and 24 flex back to their original position.
Also provided within passageway 16 are ribs 17 and 19 on opposed sides in staggered relationship to each other. Towards end 14, a pair of deflectors 21, 23 and 25, 27 are also provided on opposed sides within socket 10 .
The seal of the present invention further comprises a latch member indicated generally by reference numeral :

~, ' , - ~ : ' : . :: . . , ~ 132~71~
26. Latch member comprises an extension extending laterally from socket member lO and integrally connected thereto at a point spaced from end 12. In the illustrated embodiment, latch member 26 comprises three sections 28, 30 and 32. Section 28 is the gripping portion oE the latch member and comprises a relatively thin, flat and planar extension of the same or similar width as socket member lO tFigure 2). As shown in Figures l and 2, gripping portion 28 has a plurality of longitudinally spaced apart projections 34 which act as gripping means, as discussed hereinafter in greater detail. It will be noted from Figure l that gripping section 2~ may have a thickened area 36 along the length of projections 34 on the surface opposed to the projections 34 to provide greater strength to this portion. There is thus a thickened central strip 36 with the outer side edges oE the gripping section 28 being of a thinner nature to provide ease of flexibility and aid in forming itself around the neck of a bag.
~0 A small slot 35 adjacent the point where latch member 26 adjoins socket member lO is provided as a point of weakness where the seal can be cut or bent and broken off when it is desired to remove the seal from a containerO
Section 30 of latch member 26 is a continuation of the gripping portion 28 and comprises a "Christmas-tree"
configuration having a plurality of shoulders adapted for cooperation with fingers 22 and 24 of socket member lO. Thus, section 30 comprises a socket engaging 3Q section having a plurality of tapering sections forming shoulders 37 spaced along the length of section 30~
: ~' ' ' ' ''' "''` ' .
132~710 Secticn 32 is a strap-like member extending from soc~et engaging section 30, and has a plu~ality of spaced apart ridges 38, an enlarged head 40 and an aperture 42. Ridges 38 provide for easy gripping of the seal. Enlarged head 40 is adapted for insertion into aperture 42. Aperture 42 is of a size so that enlarged head 40 can be pushed therethrough; in this respect, slots 44 and 46 on either side of aperture 42 aid in permitting passage of enlarged head 40 through aperture 42. Ribs 43 may be provided on the outer edges of section 32 adjacent aperture 42 to provide reinforcement. Shoulders 48 of enlar~ed head 40 sit on the outer perimeter of aperture 42, and thus, the enlarged head 40 is held in the aperture 42 and cannot be removed without excess pressure being exerted.
Figures 3 and 4 of the drawings illustrate the seal in its locked position. Thus, it will be seen that the gripping portion 28 has been curved down and around with the latch member 26 being inserted through open end 12 of socket 10. Thus, gripping portion 28 creates a circular inner configuration adapted for encirclement of, e.g., the neck of a mail bag. The projections 34 thereby grip the neck of the-bag.
As the latch member 26 is~being pulled through the -socket member and the portion 32 has passed through the socket and out through end 14, shoulders 37 progressively engage fingers 22 and 24 inside the socket, with the fingers flexing further apar-t as the shoulders 37 pass therebetween. Depending on the size of 3a the neck of the bag to be closed, the latch member 26 C
;, ~, ,: ; . ., 132~71Q
can be pulled through the socket member until a tight fit of the gripping portion 28 around the neck of the bag is achieved. At this point, the fingers 22 and 24 are in engagement with one set of shoulders 37 creating a locking action; it will be understood that the latch member cannot be pulled back out of the socket due to the engagement of the fingers 22 and 24 with shoulders 36; on the other hand, the latch member can be pulled further into socket whereby a greater tightening of the gripping portion 28 around the neck of the bag is provided.
In the locked position, the opening of reduced size in end 12 of socket 10 is substantially closed off by the tapering portions of second extension member 30 and thus, access to within the socket is minimized.
Ribs 17 and 19 with their staggered positioning permit easy insertion of the latch member into the socket. Thus, with their staggered relationship, ribs 17 and 19 permit second extension member 30 to move from side to side in insertion into the socket 10. These ribs, as well as deflectors 21, 23 and 25, 27 serve also to deflect any tool which may be used in trying to disengage the fingers 22 and 24 from shoulders 37.
Once the seal has been locked around the neck of a bag, the portion 32 may then be curved around and the enlarged head 40 inserted in the aperture 42. The portion 32 may be curved around either in a downward direction relative to Figure 3, or on the other hand, may be curved upwardly and around. The ridges 38 aid in : . . ~ . -:~.
: - ' . .
3257~0 gripping the latch member and the enlarged head inserted in aperture 42, creates a circular outline. This circular outline can be used for attachment of, e.g., identification labels, destination labels, etc. Thus, for example, if the seal is being used with mail bags, a destination label could be attached by virtue of label retaining section 32. As the enlarged head is somewhat difficult to remove from the aperture, the label will not become detached from the seal and mail bag, until such time as some one purposefully removes the enlarged head from the aperture. It should also be noted that, e.g., a label can be detached and a new label attached to the seal, without the necessity of unlocking the seal or of tearing the label.
It will be noted that the fingers 22 and 24 are spaced from ends 12 and 14 and are provided approximately mid-way in the length of socket 10. This positioning creates the locking action away from the ends 12 and 14 so that anyone tampering with the seal would require a longer tool to attempt to disengage the fingers. The longer the tool, the more flexible it would be and therefore, it would be difficult to gain access to the ~ingers, past the deflectors 21, 23, 25 and 27 from one end or past the ribs 17 and 19 from the other end.
Turning now to Figures 5 to 7, a seal is illustrated which can be used in cases where other types of locking requirements are necessary. The Figure 5 to - ~32~710 7 embodiment can be used in locking a zippered pouch, cash drawers, jewelry tote boxes, etc.
Figures 5 to 7 will not be described in detail herein, apart from those features which differ from the Figure 1 to 4 embodiment. In Figures 5 to 7, like reference numerals correspond to like components in the Figures 1 to 4 embodiment, and accordingly, a detailed description of these like parts is not included herewith.
Socket 10' is similar to socket 10. However, instead of thickened walls 18, 20, socket 10' has a reduced outer diameter with flat walls 18', 20', creating the smaller opening at end 12'. Latch member 26' is comprised of first extension 28', second extension 30' and third extension 32'. First extension 28' is merely a flat extension adapted for insertion through and encircling of, appropriate means on the container to be locked. Such means may be for example, a staple and hasp as conventionally used in containers adapted for locking with a padlock, means provided on a zipper fastener, etc.
Figure 5 illustrates extension 28' as a flat strap;
Figure 6 illustrates extension 28' with a thicker central strip 36' as a strengthening feature.
Second extension 30' has locking shoulders 37' similar to those of Figure 1.
Third extension 32' acts as a guiding section to aid in insertion into the socket. ~ripping ridges 38' ,, ; ' . , : ' ~ 32~i7~0 are provided to aid in insertion. Section 32' may also be used for placement of indicia such as numbering or lettering so that such indicia would be easily readable once the seal is in use.
End 40' of Figures 5 and 6 are appropriately configured for insertion into the socket 10'. The seals of Figures 5-7 are employed in a similar manner to that of Figure 1, that is, latch 26' is placed through appropriate clasps or hooks on a container to be locked and is then inserted into end 12'. As extension member 30' passes through the socket, shoulders 37' progressively engage fingers 22', 24', until the point where the desired size has been reached.
Although in both of the illustrated embodiments, the latch member 26 has been shown as extending laterally from the socket member 10 at a point spaced from the end 12, it will be appreciated that the latch member could extend from the socket at various points thereon, for example, the latch member 26 could extend directly from the first end of the socket.
In addition, while the extension members have been shown having diminishing widths (Figures 1-5), e.g., extension member 28 being the widest, with extension member 30 being narrower, and extension member 32 being narrower still, it will be appreciated that various widths or the same widths could be utilized for all of the members, with the socket member being suitably configured to accommodate the latch member, such as illustrated in Figure 6.

In cases where no third extension member or label retaining means are required, it will be appreciated that the third extension member could be eliminated.
It will also be appreciated that the features illustrated in Figures 1 to 4 can be interchanged with those illustrated in Figures 5 to 7 and vice versa, the specific features being selected so as to provide the appropriate ones required for the specific applica~ion.
Although the invention has been described with reference to the specifics illustrated in the drawings, it will be appreciated that various modifications and changes may be made thereto, without departing from the spirit and scope of the inventionO

In a preferred form of the flexible container seal, the first extension member includes gripping and engaging means which take the form of a plurality of spaced-apart projections extending from the first flexible extension member. Generally, it is desirable to provide such projections with relatively pointed ends so as to enable a good gripping action around tha neck of a bag or flexible container. Also, the first flexible extension member may be of a thicker construction so that a thicker central strip is provided on the surface opposed to that from which the projections extend so as to improve the strength thareof. As such, a central strip of a greater thickness may be provided along the length of the first flexible extension member.
In the flexible contain~r seal, it is also preferred that a plurality of socket engaging members be provided on the second extension member so that the seal is adjustable to different sizes about the neck of a flexible container. Thus, upon insertion into tha socket member, the socket engaging members progressively engage the cooperating loc~ing means to thereby permit the required adjustment.
In a preferred form of the seals of the invention, the length of the first extPnsion member and the socket member are such that upon insertion of the second extension member into the first end of the socket member, the last one of the socket engaging members to enter the -.~
, : ,-,' , ~ 132~ 0 - 6c -socket member cannot exit the second end of the socket member.
In preferred embodiments of the seal, a preferred feature is that of the provision of a third flexible extension member extending from the second extension member. This extension member is integrally attached to the second extension member and is useful in guiding the second extension member into the socket and to pull it 10therethrough. In a particularly preferred form, the third extension member takes the form of label retaining means.
The label retaining means of the third flexible extension member preferably takes the form of a strap member having an aperture at one end and an enlarged head at the other end. In use, the enlarged head is moved towards the aperture at the other end, creating a circular outline for retaining a label attached to the seal. The enlarged head has shoulders which seat on the outer periphery of the aperture, thus holding th~ head in the 20aperture. Small sloks may be provided at opposed sides of the aperture so as to aid in insertion of the enlarged head therethrough.
The seals can be formed of any suitable plastic material such as polyolefins, e.g. polyethylene, polypropylene, copolymers of these materials, and the like.
While the first extension member requires flexibility, it may also be possible that the second and third extension members be formed of a relatively more rigid material, although for ease of construction and use, 30it is preferred that the whole seal be formed of the same material.

It will be appreciated that the seal can be appropriately sized for the particular application. Any number of socket engaging members can be provided depending on the desired degree of versatility and adjustability. In a preferred form, from 3 to 15 socket engaging members are provided to give a relatively large degree of adjustability; however, the seal would also be adjustable with 2 socket engaging members and in some cases, it may be desired to have more than 15 socket engaging members.
The lengths of the various sections of the latch member will also depend on the particular application.
In one form, the length of the first extension member is such that upon insertion of the second extension member into the socket, the last one of the socket en~aging members to enter the socket cannot exit the second end thereof.
Having thus generally described the invention, reference will now be made to the accompanying drawings, illustrated preferred embodiments of the invention, and in which:
FIGURE 1 is a side e]evational view of a seal according to one embodiment of the present invention;
FIGURE 2 is a bottom view of a seal;
FIGURE 3 is a side elevational view of a seal in a locked position;
FIGURE 4 is a view similar to Figure 3 with parts broken away.

FIGURE 7 illustrates a socke-t member in accordance with Figures 5 and 60 In greater detail, a one-piece seal for closing flexible containers according to an embodiment of the present invention comprises a socket 10 of a cylindrical or tubular configuration. Socket 10 has opposed open ends 12 and 14 communicating with a passage 16 extending through socket 10. As illustrated, open end 12 of socket 10 has a smaller opening than opposed open end 14. Thus opposed inner walls 18 and 20 form a substantially rectangularly shaped opening of reduced size in end 12 of socket 10. Located within socket 10, and extending from walls 18 and 20 is a pair of opposed, spaced apart7 resilient fingers 22 and 24. As seen from Figure 1, fingers 22 and 24 extend toward open end 14 and are directed inwardly somewhat leaving a space between the fingers of reduced size relative to the size of the remainder of passageway 16. Fingers 22 and 24 are relatively resilient in that they can be urged further apart, however, upon release of any tension thereon, fingers 22 and 24 flex back to their original position.
Also provided within passageway 16 are ribs 17 and 19 on opposed sides in staggered relationship to each other. Towards end 14, a pair of deflectors 21, 23 and 25, 27 are also provided on opposed sides within socket 10 .
The seal of the present invention further comprises a latch member indicated generally by reference numeral :

~, ' , - ~ : ' : . :: . . , ~ 132~71~
26. Latch member comprises an extension extending laterally from socket member lO and integrally connected thereto at a point spaced from end 12. In the illustrated embodiment, latch member 26 comprises three sections 28, 30 and 32. Section 28 is the gripping portion oE the latch member and comprises a relatively thin, flat and planar extension of the same or similar width as socket member lO tFigure 2). As shown in Figures l and 2, gripping portion 28 has a plurality of longitudinally spaced apart projections 34 which act as gripping means, as discussed hereinafter in greater detail. It will be noted from Figure l that gripping section 2~ may have a thickened area 36 along the length of projections 34 on the surface opposed to the projections 34 to provide greater strength to this portion. There is thus a thickened central strip 36 with the outer side edges oE the gripping section 28 being of a thinner nature to provide ease of flexibility and aid in forming itself around the neck of a bag.
~0 A small slot 35 adjacent the point where latch member 26 adjoins socket member lO is provided as a point of weakness where the seal can be cut or bent and broken off when it is desired to remove the seal from a containerO
Section 30 of latch member 26 is a continuation of the gripping portion 28 and comprises a "Christmas-tree"
configuration having a plurality of shoulders adapted for cooperation with fingers 22 and 24 of socket member lO. Thus, section 30 comprises a socket engaging 3Q section having a plurality of tapering sections forming shoulders 37 spaced along the length of section 30~
: ~' ' ' ' ''' "''` ' .
132~710 Secticn 32 is a strap-like member extending from soc~et engaging section 30, and has a plu~ality of spaced apart ridges 38, an enlarged head 40 and an aperture 42. Ridges 38 provide for easy gripping of the seal. Enlarged head 40 is adapted for insertion into aperture 42. Aperture 42 is of a size so that enlarged head 40 can be pushed therethrough; in this respect, slots 44 and 46 on either side of aperture 42 aid in permitting passage of enlarged head 40 through aperture 42. Ribs 43 may be provided on the outer edges of section 32 adjacent aperture 42 to provide reinforcement. Shoulders 48 of enlar~ed head 40 sit on the outer perimeter of aperture 42, and thus, the enlarged head 40 is held in the aperture 42 and cannot be removed without excess pressure being exerted.
Figures 3 and 4 of the drawings illustrate the seal in its locked position. Thus, it will be seen that the gripping portion 28 has been curved down and around with the latch member 26 being inserted through open end 12 of socket 10. Thus, gripping portion 28 creates a circular inner configuration adapted for encirclement of, e.g., the neck of a mail bag. The projections 34 thereby grip the neck of the-bag.
As the latch member 26 is~being pulled through the -socket member and the portion 32 has passed through the socket and out through end 14, shoulders 37 progressively engage fingers 22 and 24 inside the socket, with the fingers flexing further apar-t as the shoulders 37 pass therebetween. Depending on the size of 3a the neck of the bag to be closed, the latch member 26 C
;, ~, ,: ; . ., 132~71Q
can be pulled through the socket member until a tight fit of the gripping portion 28 around the neck of the bag is achieved. At this point, the fingers 22 and 24 are in engagement with one set of shoulders 37 creating a locking action; it will be understood that the latch member cannot be pulled back out of the socket due to the engagement of the fingers 22 and 24 with shoulders 36; on the other hand, the latch member can be pulled further into socket whereby a greater tightening of the gripping portion 28 around the neck of the bag is provided.
In the locked position, the opening of reduced size in end 12 of socket 10 is substantially closed off by the tapering portions of second extension member 30 and thus, access to within the socket is minimized.
Ribs 17 and 19 with their staggered positioning permit easy insertion of the latch member into the socket. Thus, with their staggered relationship, ribs 17 and 19 permit second extension member 30 to move from side to side in insertion into the socket 10. These ribs, as well as deflectors 21, 23 and 25, 27 serve also to deflect any tool which may be used in trying to disengage the fingers 22 and 24 from shoulders 37.
Once the seal has been locked around the neck of a bag, the portion 32 may then be curved around and the enlarged head 40 inserted in the aperture 42. The portion 32 may be curved around either in a downward direction relative to Figure 3, or on the other hand, may be curved upwardly and around. The ridges 38 aid in : . . ~ . -:~.
: - ' . .
3257~0 gripping the latch member and the enlarged head inserted in aperture 42, creates a circular outline. This circular outline can be used for attachment of, e.g., identification labels, destination labels, etc. Thus, for example, if the seal is being used with mail bags, a destination label could be attached by virtue of label retaining section 32. As the enlarged head is somewhat difficult to remove from the aperture, the label will not become detached from the seal and mail bag, until such time as some one purposefully removes the enlarged head from the aperture. It should also be noted that, e.g., a label can be detached and a new label attached to the seal, without the necessity of unlocking the seal or of tearing the label.
It will be noted that the fingers 22 and 24 are spaced from ends 12 and 14 and are provided approximately mid-way in the length of socket 10. This positioning creates the locking action away from the ends 12 and 14 so that anyone tampering with the seal would require a longer tool to attempt to disengage the fingers. The longer the tool, the more flexible it would be and therefore, it would be difficult to gain access to the ~ingers, past the deflectors 21, 23, 25 and 27 from one end or past the ribs 17 and 19 from the other end.
Turning now to Figures 5 to 7, a seal is illustrated which can be used in cases where other types of locking requirements are necessary. The Figure 5 to - ~32~710 7 embodiment can be used in locking a zippered pouch, cash drawers, jewelry tote boxes, etc.
Figures 5 to 7 will not be described in detail herein, apart from those features which differ from the Figure 1 to 4 embodiment. In Figures 5 to 7, like reference numerals correspond to like components in the Figures 1 to 4 embodiment, and accordingly, a detailed description of these like parts is not included herewith.
Socket 10' is similar to socket 10. However, instead of thickened walls 18, 20, socket 10' has a reduced outer diameter with flat walls 18', 20', creating the smaller opening at end 12'. Latch member 26' is comprised of first extension 28', second extension 30' and third extension 32'. First extension 28' is merely a flat extension adapted for insertion through and encircling of, appropriate means on the container to be locked. Such means may be for example, a staple and hasp as conventionally used in containers adapted for locking with a padlock, means provided on a zipper fastener, etc.
Figure 5 illustrates extension 28' as a flat strap;
Figure 6 illustrates extension 28' with a thicker central strip 36' as a strengthening feature.
Second extension 30' has locking shoulders 37' similar to those of Figure 1.
Third extension 32' acts as a guiding section to aid in insertion into the socket. ~ripping ridges 38' ,, ; ' . , : ' ~ 32~i7~0 are provided to aid in insertion. Section 32' may also be used for placement of indicia such as numbering or lettering so that such indicia would be easily readable once the seal is in use.
End 40' of Figures 5 and 6 are appropriately configured for insertion into the socket 10'. The seals of Figures 5-7 are employed in a similar manner to that of Figure 1, that is, latch 26' is placed through appropriate clasps or hooks on a container to be locked and is then inserted into end 12'. As extension member 30' passes through the socket, shoulders 37' progressively engage fingers 22', 24', until the point where the desired size has been reached.
Although in both of the illustrated embodiments, the latch member 26 has been shown as extending laterally from the socket member 10 at a point spaced from the end 12, it will be appreciated that the latch member could extend from the socket at various points thereon, for example, the latch member 26 could extend directly from the first end of the socket.
In addition, while the extension members have been shown having diminishing widths (Figures 1-5), e.g., extension member 28 being the widest, with extension member 30 being narrower, and extension member 32 being narrower still, it will be appreciated that various widths or the same widths could be utilized for all of the members, with the socket member being suitably configured to accommodate the latch member, such as illustrated in Figure 6.

In cases where no third extension member or label retaining means are required, it will be appreciated that the third extension member could be eliminated.
It will also be appreciated that the features illustrated in Figures 1 to 4 can be interchanged with those illustrated in Figures 5 to 7 and vice versa, the specific features being selected so as to provide the appropriate ones required for the specific applica~ion.
Although the invention has been described with reference to the specifics illustrated in the drawings, it will be appreciated that various modifications and changes may be made thereto, without departing from the spirit and scope of the inventionO
