PROCEDURE FOR MANUFACTURING SEALING CAP

The present invention relates to a process for the manufacture of a closure having a vibration stopper which, when mounted on a container, allows for the storage of various materials in a vibration seal and for the gas-tight closure of the container.

A significant group of iabtetase five drugs do not have sufficient strength, which results in the tablets crumbling after packing and crumbling in the sealed container. Strengthening the strength of the tablets is not a solution to this problem, as the tablet must remain peelable and load-bearing. A not insignificant part of the drug tablets is very sensitive to moisture, in addition to dusting.

To eliminate the crumbling problem, a. it is also possible to place a flexible material or accordion-like vibrating damping element over the medicaments in the storage vessel, which is preferably carried out in conjunction with other parts of the cap in order to avoid loss or deterioration.

A solution for storing moisture-sensitive drugs is known to incorporate a moisture scavenger, which is understood by the drug storage space through perforation or otherwise.

However, a significant problem with moisture-sensitive pharmaceuticals is that, despite the fact that the containers provide a gas tight seal during manufacture and placing on the market, this can disappear over time due to the use of zarok cap material due to use ο

£.

U.S. Pat. No. 4,279,361 discloses a closure cap which has an integrated vibration-suppressing element and provides gas-tight closure and waterproofing. The known solution has the disadvantage that it does not have any protection against poorer resealability due to the use of the closure material. As a result, the closure cap will not be able to provide a gas tight seal and moisture protection for the material stored in the container it is sealed over. A further disadvantage of the known solution is that it is not provided with a warranty lock that provides an on-line upgrade

Document DE 2ÖÖ4S2S 111 discloses a water-tight closure cap provided with a chamber filled with moisture-absorbing material. EP 6 763 477 A1 also discloses such a closure. DE 2941916 A1 discloses a resealable closure with a vibration damping element in which the vibration collar member is fixed to the closure but is not made of one piece. The closures disclosed in those patents, when mounted on a container, provide a solution to the vibration and / or moisture sensitivity of the material stored in the container they seal, but have one of the disadvantages described above,

A closure with a tensioning insert is described in U.S. Patent No. 5,789,263. Solutions for dehumidifying and damping vibrations are disclosed in FR 2 343 857 and US 4 215 788.

The sealing cap with vibration dampener is designed to attach vibration damping and gas tight seals to a secure Hson container to provide protection against moisture from various objects inside it and to maintain gas tight sealing for any period of time - typically up to several years ™ , and is counted as the number of re-positions of re A <

this securing device has a sealing surface supported by a tensioning insert with a correspondingly extending cylindrical side portion on which a protrusion is formed. The tensioning insert further comprises a lid. By inserting the tension insert into the opening formed in the closure cap, it is advantageous to create a circumferential protrusion on the wiped surface which, when mounted on the container cap, engages the container mouth circumferentially, thereby providing a gas tight seal. The top of the tensioner insert covers the opening in the closure cap. The expansion cartridge may conveniently be made of a material harder than the material of the closure to achieve the desired purpose, and may be embodied in several embodiments, of which in the following embodiments

The above closure is particularly suitable for a container for storing drugs when the stored drugs are prone to crumbling, tearing, and therefore sensitive to wetting and / or wetting, so that the gas tight closure and humidifier are typically silicone - It is. In all cases, the vibration damping element is configured for elastic deformation, preferably in the form of an accordion. It is possible to design the closure cap in which a perforation is provided on the vibration damping element. The vibration damping element has an interior space enclosed by a non-removable tension insert which is designed to hold a moisture-hardening material, preferably a siliceous material. The perforation allows the moisture curing agent to come into contact with the interior of the sealed container through the perforation and provide moisture retention. It also absorbs the moisture in the air inside the tank,

In the case of a closed cap vibration damping element without a perforation, the vibration damping element has an interior space. When this interior is sealed with a non-destructive, manually removable and properly resealable tension insert, the interior is designed to support an object, preferably a sample, advertisement, instruction manual or leaflet, since storage spaces are provided in the interior of the shock absorber and in the interior of the container. spaces that are hermetically sealed.

Preferably, the closure caps are provided with a tamper evident filament tear-off strap which includes a flap that removes the tamper evident when the closure cap is mounted on the container. The closure further includes a tamper-evident flap on the mouth of the container.

Preferred embodiments of the closure will now be described with reference to the drawings, in which the process for making the closure is described and described in detail.

Figure 1 is a side cross-sectional view of a preferred embodiment of the closure 10 in which the connector 24 and the vibration damping member 14 are integrally formed and the closure 10 is mounted on a container 12 by the connector portion 24 of the closure 10. The vibration damping element 14 ensures that the stored material 28, shown in Figure 8, placed inside the container 12, is less crumbly, crushed, and superior to the effects of vibration. The connecting portion 24 of the closure 10 comprises an outer cylindrical portion 37 and an inner cylindrical portion 38. The inner cylindrical portion 38 is joined to the vibration damping element 14, when formed in one piece, the joint is formed by fusing the inner cylindrical sheath connecting portion 24 to the vibration damping element 14. The preferred embodiment includes a tension insert 11 shown in FIG. The tensioning insert 11 is preferably provided with a flange 23 formed on the top 40, which is an element allowing manual removal of the tensioning insert 11 without being damaged. Thus, the flange 23 can be used to remove and reinstall the tensioning insert 11 from the arrow 27 without being damaged. Thus, an object 13 can be placed inside the interior 32 of the vibration damping element 14 in the closed configuration of the vibration damper element 14. The object 13 may be, for example, a sample, advertisement, instructions for use, leaflet or other object.

The security lock 17 shown in Figure 1 is provided with tear straps 18 securing originality to the outer portion 37 of the connecting portion 24, which can be peeled off by means of a locking tab 16. When mounting the tab 18 on the container 12, the tongue lock 17 is folded down to facilitate tearing off, as shown in the side view of the closure cap 10 in FIG. By means of the flange 19 forming part of the outer cylindrical shell 37, the container 12 can be closed again after removing the warranty lock 17. To this end, the mouth of the container 12 is provided with a protrusion 42 on which the flange 19 snaps into place when the closure cap 10 is placed on the container 12. The latch 17 does not play a role in securing the closure cap to the container, only secured by the tear strands 18 to provide the original material 28 stored in the interior 15 of the container 12 until the latch 17 is broken. The present embodiment is preferably mounted on a container for stored materials 28 which require a gas tight closure which is prone to crumbling.

Fig. 2 shows a further preferred embodiment of the closure lid lo, in which the connecting part 24 and the anti-slip member 14 are also made in one piece. This preferred embodiment comprises a tension pad 11 '. The clamping insert A111 is configured, preferably using a flange 26, so that it can be removed only by destruction, so that the interior 32 of the vibration damper 14, the side view of the closure 18 in FIG. in an oblique embodiment of the embodiment shown with its perforations 29, to accommodate a moisture-binding material 25. Thus, this embodiment is advantageously suitable for storing moisture sensitive storage material 28 which is sensitive to crumbling and requires a gas tight seal, since the vapor bond is provided by the vapor binder 25 through the perforation 29, which binds the vapor that enters during the opening seal. , because the continuous penetration of moisture is prevented by a gas tight seal.

Mounted on the container 12, the closure cap 11 and the tensioning insert 11 'provide a gas tight closure for the stored material 28 in the interior 15 of the container 12. The circular protrusions 22 on the outer surface of the tongue insert 11 and tension insert 11 A protrusion 21 is formed on the sealing surface 20 of the inner cylindrical body portion 38, creating a circular contact surface between the cooking surface 20 and the mouth of the container 12. The circumferential contact surface ensures that when the closure cap 10 is mounted on the mouth of the container 12, no material can enter the interior space 15 of the container 12. The sealing cap 10 provided with the tensioning insert 11 and the tensioning insert 11 'is particularly advantageous for securing the gas tight closure after any number of removals and removal of the closure 10 and aging of the sealing cap material 10.

Figure 3A is a perspective view of an embodiment of the closure 10. The figure shows, from a different point of view, the design of the warranty closure 17, the tear-off tab 18 and the vibration damping element 14 on the closure 10. The elements listed in Fig. 38 can be viewed from a different perspective in the side view drawing of the same embodiment of the closure cap. Figures 3A and 3B illustrate the bellows-like configuration of the vibration damper member 14 and the fit of the tab 16 on the outer locking portion 37 of the coupling portion 24 to the outer cylindrical portion 37. Figure 3C is a side view of the same embodiment of the closure 10; shows a cross-sectional drawing without showing the strain relief 11 or the strain relief 1Γ. If the strain relief 11 or strain relief 1Γ is not inserted into the opening 27 defined by the top of the sealing cap 33, the protrusion 21 will not appear on the sealing surface 20 of the stopper 10, so that the gas tight seal

Fig. 4 is a cross-sectional view of an embodiment of the closure cap 10, showing the tensioning insert 11 separately. The tensioning insert 11 shows a stepwise formation of a flange 23 which allows non-destructive removal of the tensioning insert 11. The figure shows that without inserting the tensioning insert 11 into the opening 27, the protrusion 21 does not appear on the smooth surface 20 of the sealing cap. The circumferential protrusion 21 very advantageously provides the filling surface 20 with a gas-tight seal on the mouth of the container 12.

Figure 5 is a cross-sectional view of an embodiment of the closure 10 in the position where the tension insert 11 is inserted into the opening 27 in the closure 10. In this case, the circular protrusion 22 on the side of the tensioning insert 11 creates a protrusion 21 on the sealing surface 20 of the closure cap 10 which, when mounted on a container 12, provides a gas tight seal. It can also be seen that the stepped configuration of the flange 23 of the tensioning insert 11 fits into the edge of the opening 27.

She.

FIG. 4A is a cross-sectional view of an embodiment of the closure 10, shown separately in the tensioning insert. It can be seen that by removing the tension insert 11 it is possible to insert the object 13 into the interior space 32 of the vibration damper element 14. 7 is a side view of an embodiment of the closure 10 shown in FIG. The cross-sectional drawing shows, where possible, the non-destructive removal or re-insertion of the tension insert, which allows storage of an object 13 inserted into the interior 32 of the vibration damper element 14, which provides further possibilities for using the closure 10. Advantageously, for example, when storing a medicament, the container 12 enclosed by the closure cap 10 can be marketed without a box, which may be economical, environmentally friendly, as instructions, leaflets or other descriptions may be stored inside the enclosure 32 of the sealing cap 14.

FIG. 8 is a cross-sectional view of an embodiment of a needle closure mounted on the container using a tension insert 11; The figure shows the material 28 stored in the inner space 15 of the container 12. The stored material 28 protects the vibration damping effect 14 from physical impacts due to crumbling, crushing and shaking by significantly reducing the amount of movement of the material 28 or by squeezing the material 28 to prevent any movement within the container 15. The figure shows a cross-sectional view of the closure cap 10 and the container 12 which do not show the tear strands of the material stored inside the container 15 which serves to tear off the guarantee lock 17 or the container 12, but only the circumferential guarantee closure 17 is shown. . Thus, and with reference to the stored material 28, this figure is called to emphasize the essential functionality of the closure 10.

Fig. 9 is a cross-sectional view of an embodiment of the closure cap 10, with the tension insert 11 removed from the opening 27 in the direction indicated by the arrow, not shown separately from the closure cap 10. The figure does not show the removed warranty closure 17 but the closure of the closure 19 flanges secures it independently of the 17 garaneiaars. It is shown that by removing the tensioning insert 11, the object 13 inserted into the interior space 32 of the vibration damping element 14 can be removed through the opening 27 at the top of the closure 10.

Fig. 10A is a perspective view of an embodiment of the closure cap 10 showing a perforation 29 on the underside of the vibration cuff member 14, which allows the vibration cuff member 14 to be disposed within its inner space 25. Through the perforation 29, the vapor retaining material 25 can provide an antifreeze for the stored material 28 located inside the container 15. This embodiment, comprising element 14 with perforations 29, requires the use of a tension insert 11 '. Advantageously, the tensioning insert 1Γ can only be removed from the opening 27 by destruction, since the vapor retaining material 25 is properly effective when placed in a closed space and can only contact the stored material 28 through the perforation 29. The use of the present embodiment with or without tensioning insert 11 is not advantageous; placing the vapor binder 25 in an open or open space without proper control of moisture

FIG. 108 is a side elevational view of the closure 10 without showing a tension insert 11 or a tension insert 1T.

Figure 11 is a side view of an embodiment of the closure 10; A cross-sectional drawing of the container 12 is shown using the 1T tension insert. The figure can be observed. that, due to the protrusion 22 of the tensioning insert 1 f, the clamping bracket 21 is disposed on the filling surface 20 and is fitted with a gas-tight closure to fit the salt side of the container 12 and the flange 19

Fig. 12 is a cross-sectional view of the closure 10 mounted on the container 12 without showing the tension insert 11 or tensioning insert 1T. The connector portion 24 of the closure lid is secured to the mouth of the container 12,

Fig. 13 is a cross-sectional view of an embodiment of the closure cap 10 without showing the tension insert 11 or tension insert 11 ', showing the compressed state of the vibration damper 14 by a dashed line and showing the deviation H of the vibration damper 14 without compression. The resilient foam compressibility of the vibration damping element 14 ensures that the stored material 28 in the container closed by the closure cap 10 is prevented from crumbling, shredding and that the stored material 28 is more resistant to the physical effects of vibration.

A cross-sectional drawing of a Daizeef is shown, mounted on the container 12, without the tension insert 11 and the 1T tension insert. The tab 18 is exposed by the protrusion 42 of the mouth of the container 12. Deflection of the top 18 facilitates the release of the warranty strap 17, after which the closure cap 10 can be removed from the mouth of the container 12 The closing cap 10 may be water-fastened to the mouth of the container 12 by the snap flange 18.

Figure 12 is a perspective view of an embodiment of the closure cap 10; with a sealed vibration damper 14, the warranty lock 17 shown in Fig. 15B, removed by a. Closing Cap 10 With the removal of the warranty lock 17, the tear strands 18 are torn apart, 33 parts remain on the warranty lock 17 and 34 remain on the closure 10. The tear strands 18 ensure the onalization of the stored material 28 in the interior 15 of the sealed container 12

Fig. 18 is a cross-sectional view of an embodiment of the closure 10 mounted on the container 12 with the tension insert TT removed with the warranty lock 17 removed. After removal of the warranty lock 17, the remaining snap-on flange 19 allows the closure cap 10 to be reattached to the mouth of the container 12, the protrusion 42, and the gas tight closure is still provided using the tensioning insert 1T. Thus, preferably, the removal of the seal 17 will not alter the functionality of the closure 10, but only the material 28 stored in the container 12 will no longer be angled.

Also disclosed is a method of making a sealing cap integrated with a vibrating tab member in accordance with the present invention. In the process, the connection part and the counterpart of a vibration bar member in the initial production phase, the form part, are formed from two materials of different viscosity. Both parts are made of polyethylene, preferably in low and high density versions. Instead of their viscosity, the materials are characterized by their flow index, which is inversely proportional to the viscosity. The coupling portion is made of a material optimized for injection molding, such as HÖPE (high density polyethylene) or IDPE (low density polyethylene), the material used typically having a flow index of from about 2 to about 30 g / L. The preform is made from injection-optimized LÖPE material (hereafter "blasting material"), but at the level of injection molding, which material has a flow index typically of about 0.3 g / L, i.e., the blowing material has a higher viscosity than the injection molding material.

-13The process consists of the following steps: first, the molding part is molten and injection molded at an initial temperature above 2 ° C * C, during which the applied material cools in the tool to take the shape of the mold part of the tool. it does not remain in the mold cavity until it has cooled completely, but when it cools down to 110-130 ° C, it is transferred to the die mold cavity within the same tool. In this tool, the partially cooled joint portion is already located in its proper location, the annealing portion of which is melted into the preform portion by melting the heat energy produced during the injection molding process, thereby fusing the joint portion and the preform portion. Meanwhile, under the action of high pressure air in the mold cavity used for the blow molding, the still plastic preform portion is compressed into the form of the shock absorber bellows, thereby forming a bellows-like shape forming the vibration damping element. When cooled, this forms the final shape of the vibration softener with elastic properties which, after fusion and joint cooling, becomes one piece with it. Since both materials are preferably polyethylene, proper fusion can be easily achieved.

Both parts of the closure can be colored during manufacture. The connecting part is typically worth coloring as it is opaque and translucent in its natural color. The vibration damper perforation is provided for the proper application of the aforementioned moisture-hardening material, and the expansion sleeve is also inserted

The process for making the closure 10 integrated with the vibration damper element 14 is illustrated by the following drawings.

Fig. Tér7 tér is a perspective view of an embodiment of the closure cap 10 in a production state in which the vibration ski element 14 has not yet become final; the vibration cushion element 14 is formed from 35 molds. In a next step, the preform portion 35 reaches its final shape by blowing high pressure air. The 35 preforms to be blown out are already one

The unit 14 is already united by fusion with the connecting part 24 of the loose seal This manufacturing state is followed by further machining but at this stage the loose seal has all the properties apart from the vibration dampness. Figure 17.8 is a side elevational view of the closure 10 showing the preform portion 35 to be challenged in the production state of the tag.

The direction of flow of the high pressure gas 36 is indicated in the figure by small arrows. This forming operation does not require the closure cap 10 to be in a plastic state during the forming operation.

Fig. 198 and C illustrate the excess material 45 on the preform portion 35 required to connect the preform portion 35 to the connector portion 24. abundant for melting the thinned edge of part. In fact, during the fusion operation, a preform portion 35 having a temperature of 11 ° to 13 ° * € is connected to the cooled connection portion 24. Figures 20A-U show the production states listed above in a bottom view, which also illustrates the production process. Fig. 2QA shows a connector portion 24 with a central opening for inserting a tension insert 11.1, a bottom portion of the preform 35 already attached, and a lower portion of the vibration damping member 14 in Fig. 2A. Fig. 21A shows the initial state, Fig. 22B the attached live form part 35 and Fig. 22C the final state of the vibration damper element 14.

the one-piece design of the closure helps to prevent the vibration damping element 14 from separating during use, which is often the case with manufactured vibration damping elements.

The invention is, of course, not limited to the preferred embodiments shown in detail, but further variations, modifications and improvements are also possible within the scope of the claims.

In addition to the embodiments shown, it is also possible to use, for example, an annular tension insert, preferably provided with stiffening, which is formed on the wiped surface to provide a gas seal protruding against the gas cap of the sealing cap. ring included. The resulting tension ring can be reinforced with any shape insert, such as a cross-shaped, polygonal insert, or a preferably disc-shaped insert, which is essentially a material.

- Ίο saturated ring. An arbitrarily shaped disc-shaped ring ensures that the interior of the vibration dampener is enclosed, or can be provided with any means for non-destructive removal, or if necessary to prevent non-destructive removal.

Alternatively, the design of the security lock and the entry assist tab may be labeled.
