Container closure and method of application same

The invention relates to a container closure _? a method for attaching the same to a container and the container closure formed by the method "

When closing a container with a closure or It is common for a cap to provide a seal or seal which seals the container against leakage the contents of the container and protect against the ingress of contamination. This seal can be attached to a number of of points may be provided, the usual sifting at the level of the mouth of the container and with retention means is provided on the container and on the closure outwardly of the seal ". Other combinations have provided a seal under the retention means, so that impurities are not rimd around in the closure the restraint in the combination sammela ketonen.

Bs is also known as in TJS patents 3,286,868 3 286 867 is disclosed, two sealing seals vorsue © h.en, one of which the lock against the container in height the container mouth, while the other

the lock against the container outside of the lock back sharks temitt a seals. As described in these patents, the double cap prevents insect intrusion in the area of the restraint means and also prevents the contents of the container from being collected the means of restraint.

Although the closure container combinations in US Pat. Nos. 3,286,868 and 3,286,867 prove useful in preventing have proven to penetrate the area of the restraint means, the external closure in this can be Combination of water or other gaseous or liquid impurities does not prevent it from reaching the range of the Restraint means prevent the exterior of the sealed container from being subjected to a relatively high pressure as it is occurs when such a combination of the autoclave action exposed to high vapor pressure or the like. Accordingly, there is an improved closure-container combination desirable, which provides a high pressure seal on both sides of the closure retaining means, to substantially contamination of the contents of the container and the retention means to prevent.

According to the invention, a closure for sealing a container is provided, the closure retaining means thereon and an outwardly protruding circumferential bead below the closure retaining means, the closure including an upper end wall with a peripheral skirt or rim, which hangs down therefrom, the circumferential jacket having a has upper part which can be deformed against the closure retaining means on the container, as well a band at the lower part thereof which contains a ledge or surface that is substantially outwardly from the bottom of the top of the jacket and above the tape, the jacket further being a compressible Has closure or sealant which is in it

final jacket shows under the bead on the container inlet mouth, and

Fig. 5 shows the Pig. 1-4 similar view- showing a represents completed closure container combination.

The invention is illustrated and described so that it can contains a rolled anti-theft lock that is particularly suitable for closing a container for intravenous solutions for hospitalization purposes. ■ -.

1-5, FIG. 1 shows a closure 10 which is formed from sheet metal or other permanently deformable material, preferably from sheet aluminum, which is placed loosely over an inlet opening 12 of a container 14. The container 14 is preferably made of glass, although other permeable materials known in the container industry can be used, such as plastic and metal. The container 14 has an inlet opening 12. inclined retention means 16 thereon, which in the preferred embodiment are threads, although other commonly known retention means can be used. A circumferential bead 18 is disposed below the restraint means 16 and preferably extends from the container main body beyond the restraint means 16, although this is not considered to be critical to the invention. The bead is essentially rectangular in cross-section and has a relatively small radius H- at the upper outer corner and a different radius R _? at the bottom outward corner · 'The radius R ₁ on the bead 18 is approximately 2 mm (5/64 ") in the preferred embodiment, ^{which is chosen for the purpose of} illustration, but the invention is not limited to this. Per radius IL is relatively small, utn-'an effective lightening of the lock ΪΟ at the "BehaMerS I ^'sa-n" at this point

as discussed below. The radius Rp acts to receive an anti-theft tape 20 at the bottom of the closure 10, and the dimensions of the radius Hp are not critical and can vary as would be understood by one skilled in the art.

The closure 10 includes a tip end wall 22 and a depending peripheral jacket 27 and a knurled band 24 can be attached to it at the corner between the tip end wall and on the sheath to facilitate grasping the closure for removal and reattachment. Of the The depending jacket 26 extends downwardly from the tip end wall 22 and may be an inwardly directed one Have circumferential rib 27 near the tip end wall 22, which lip 27 serves to retain a composite die against the bottom surface 30 of the tip end wall.

The sealing liner 28, chosen for illustration, contains a composition of materials that is particularly suitable for sealing intravenous solution. It will be understood, however, that other sealants that known in the art can be used in a closure of the invention for sealing clay containers.

The composite end liner 28 may include a bottom layer of gilsonite 32, an intermediate layer made of rubber 34, a metal disc 36 provided with a splash and a top layer of high density polyethylene synthetic fiber 38, such as Mari ex, which the tip end wall 22 of the Closure is facing. The metal disk 36 is special designed to retain rubber layer 34 around its perimeter! so that the rubber does not squeeze outwards * can be if the upper seal pressure against the Closure 10 is applied. Variations in ..composition,

the coated seal can then be heated to set the plastisol in place. When cured, the plastisol is preferably adhered to the closure shell 26 so that the compressible liner 44 does not fall out of the closure 10 during treatment. Plastisol is used as an example and it will be understood that other materials can also be arranged in the jacket 26, for example rubber ^w 0 "hinge or polyvinyl chloride seals among others.

The band portion 20 of the jacket 26 extends from the Corner 60 of the sealing surface 40 downwards and may have at least one bottom edge that extends below the after outwardly protruding bead 18 may be formed on the container 14 and may have a line of weakness 46, e.g. a line of slits and bridges that are circumferentially are arranged, separating a barrier tape at the bottom of the closure from the remainder of the closure. the Bridges in the fastener jacket are designed to break when the fastener is removed in order to attach the locking tape to leave the container 14. Such a barrier tape is commonly referred to as an anti-theft tape because it makes it clear whether a container-closure combination has been opened or tampered with.

The aforesaid description of a closure with a locking or anti-theft strap thereon is a preferred embodiment of the invention, it being noted that there are other means of providing a closure to make theft-proof. For example, a closure of the invention may have a series of slits around it and have briquettes that separate a barrier tape at the bottom of the closure from the remainder of the closure and can also have a plurality of vertical lines of weakness, e.g.

- 9 309828/0368

Removal of the seal from a container "Break the tape into segments between the broken vertical lines. When such a seal is removed from a container, the segments may flex along the line of the bridges and outwardly due to the camming action of the container's locking shoulder The segments remain attached to the closure shell and are removed with the closure A closure according to the invention can also have only a plurality of vertical score lines in the lower part of the closure shell which can be rotated under a locking shoulder on a container and thereby To provide a barrier effect and does not include a perimeter of slots and bridges. " When such a closure is removed from a container, the vertical score lines break to divide the bottom portion of the closure shell into segments between the broken notches. These segments can penetrate the cam action of the locking shoulder on one Containers are bent outward to permit removal of the closure with the segments attached.

Pig. 2 shows the closure 10 in the first stage of FIG Attachment of the closure to the container inlet mouth 12. The closure 10 is over the container inlet mouth 12 is set and a downward pressure of approximately 90.7-320 kg (200-700 pounds) and preferably is applied About 136 kg (300 pounds) performed on the closure 10 with the pressure block 50 or the like Standard capping machine, not shown, is attached.

The top of the drooping peripheral coat is then against the inclined closure restraint means deformed on the container H by means of rollers 52 while

- 10 309828/0368

the peak pressure on the closure 10 is maintained with the pressure block. To cause this deformation, the rollers 52 are moved against and around the closure shell 26 to keep it continuously against the container retaining means 16 to ^ form and thereby threads in the closure jacket 26 to form. The peak pressure originally seals the closure 10 at the container inlet mouth 12 and the deformation of the closure jacket 26 against the inclined retaining means 16 stops the closure 10 the container in addition to the upper sealing insert to hold against the closure 10 and the container inlet mouth, whereby the container 14 with a highly integrated Lace closure is provided. Alternatively, it is also assumed that it is possible to secure a closure that has embossed threads, on a container on which such a closure on the container without the application of any external pressure is rotated so that the closure ropes when it is on the container is rotated.

A second capping machine, not shown, next seals the closure 10 against the container 14 'to provide a bottom seal outwardly from the closure retention means, as shown in FIG. Downward pressure is applied against the sealing surface 40 with a collar or bushing 54 which preferably has a tapered throat therein to apply substantial downward pressure against the surface 40 and the rounded corner E _{1 of} the container bead 18. The exertion of the substantial downward pressure against the closure 10 at the sealing surface 40 compresses the sealing insert 44 against the relatively small tip radius R _{1 of} the container bead 18 to form a seal therebetween.

Pressures of approximately ^ "6 kg (JOO pounds) are found to be good to be used for such purposes, although pressures are believed to be in the range of 45.4-227 kg (100-500 pounds) can be used.

. Figure 4 illustrates the step of tying around the buckle 10 Estigen the container 14 too deep, with a bottom part 20 under the container bead 18 with a molding tool . is flexed while the collar 54 is applying substantial downward pressure against the sealing surface 40 of the closure 10 is maintained. Hachdem the band 20 under the bead 18 with the Hadius Rp has been turned over, the pressure on the Federal government 54 released against the surface 40 and the inward turned edge of the closure 10 against the container bead holds the bottom portion of the closure in a retained position State where the sealing material is compressed against an upper surface of the container bead 1 &.

From the above description it can now be seen that the invention provides a tightly compressed seal on the inner surface of the closure sealing surface 40 and forms the container bead 18, as shown in FIG. 5 is shown. The sealing or sealing material 44 is through the lower restriction held by the bottom part of the belt 20 under compression after this part on the Corner Rp -under the container bead 18 is turned over. Although some previously known closures are sealed against the container at this relative position, earlier Closures yielded at sealing pressures created by an intermediate seat of the seal against the container are and have not sealed by the aid of an external force compressing the seal against the container, such a compressed seal thereafter through the rolled edge of the anti-theft tape

is maintained on the lock. The earlier known Closures, therefore, could not maintain their integrity when the container and its contents were relative exposed to high internal or external pressures such as those used during an autoclave process of a sealed Container were generated. With the present invention, however, high pressures are generated during sterilization are developed in autoclave devices, the seal outward from the closure retaining means is not Eliminate as this seal is under compression by the rolled edge of the closure under the container bead is maintained. The lower seal according to the invention is essentially impermeable to all impurities, be they solid, liquid or gaseous, namely both at room temperature and pressure and elevated temperatures and pressures that are normally used to medical To sterilize agents in an autoclave, well the lower closure or closure is effective against and partially is compressed around the container bead with a relatively small radius. This is a major improvement over previous closures which did not compress a gasket outwardly from the closure restraint emit te In included.

Removal of the closure 10 from the container 14 can be be carried out in-which the shutter 10 relative to the container 14 is rotated. Because the lower edge of the anti-theft Band 20 is swept under the container bead 16 and the üana no vertical weakening in the explanation Has chosen closure, the tape cannot be removed from the container. Instead, the anti-theft tape is used 20 from the remainder of the fastener 10 at the dividing line separated around their perimeter, and arar by breaking

of bridges 48. The anti-theft tape 20 "remains on the container 14 after the closure 10 is completely removed. However, in some of those previously described alternative forms of closure according to the invention which include vertical notches in the locking tape portion of the closure The vertical notches are designed to break when the clasp is removed to insert the tape into the To divide segments, which are removed with the closure.

The closure 10 can be reattached to the container 14 by screwing it onto the container 14. When the closure 10 is reattached to the container 14 a seal or seal is made on both the container inlet opening 12 and the container bead 18, although the termination on the container bead 18 is not held in compression as it was previously with the original ones Openings was the case. However, this is not important as the container-closure combination is normally not the autoclave effect or high pressure differentials subsequent to the original opening of the same is subjected. The anti-theft tape 20 is used by the Closure 10 separated in such a way that a visual inspection of the Packaging reveals whether the closure-container combination has been previously opened.

it can therefore be seen that there is an improved closure and method of applying the same to a container is illustrated and described in which a closure outwardly of the container retaining means on the container is created to prevent contaminants from entering the space between the closure jacket and the container
