Description

MOUNTING OF CONHC3CTQ ANTErEnEMT S OF INvEHTION This invention relates generally to a closure system for a container that includes a lid and a conduit assembly or discharge mouth for reception by adjustment in the neck of the container. More specifically, the present invention relates to a lid and duct assembly, and a method for assembling in lid and duct assembly to a container, wherein the lid and duct assembly includes a tamper-indicating cap, that fits under pressure, and a spout that fits under pressure. Many types of closures are known for sealing the neck of a container including a conduit received in a neck of a container and a lid for closing the conduit. Typically, the cap is threaded onto the conduit, and the conduit and / or the cap are threaded into the neck finish of the container or are clamped around the neck finish of the container by means of a separate fastening ring. For example, U.S. Patent Nos. 4,236,629 for D inell, 4,632,282 for Nagashima and 4,568,006 for Mueller et al., Describe various fastening ring arrangements for securing the duct over the REF: 23665 neck of the container, whereby the clamping ring It is constructed of a malleable metal. A disadvantage of this type of closure is that the metal clamping ring can not be recycled together with the various plastic components and, therefore, must be detached from each container before recycling. Another disadvantage is that an additional assembly step is required to assemble the clamping ring to the conduit before assembling the lid. Another example of a closure that seals the neck of a container is found in U.S. Patent No. 5,004,126 to Klesius, which discloses a plastic closure for a plastic container that includes a frame cap adapted to be threaded into the neck of an externally threaded container. on a flexible spout. The frame lid is joined in a brittle manner and is integral with a threaded ring adapted to be threaded onto the neck of the externally threaded container. A disadvantage of this type of closure is the possibility of breaking the frame cover of the screw ring during the threading of the ring on the neck of the container. Although a flexible mesh is provided between the cap and the ring to absorb excessive tapping forces, excessive radial forces beyond those accepted by the flexible network can still result during the assembly of the cap and the ring on the container neck so that they break the fragile lid and the ring joint, so they damage its function to indicate misuse. In addition, in many applications the tolerances of the neck of the container are not strictly controlled and depend on the accumulated tolerance in the lid, the duct and the neck of the container, the duct prematurely can be housed on the neck of the container so that a threaded Continuous ring on the neck of the container breaks the fragile lid and the ring joint. Other closures that seal the neck of a container include a snap-fit conduit on the neck of the container and a screw cap on the neck of the container on the pressure-fitting conduit. For example, U.S. Patent No. 4,917,270 to Simon discloses a closure device that includes a conduit received in a slot provided in the neck of the container, wherein the conduit elastically deforms over the neck of the container during installation to receive in the slot. U.S. Patent Nos. 5,108,009, to Davidson et al., And 4,706,829 to Li describe other similar interlock and container neck configurations. Still, there is a need for an improved snap-fit closure for universal use with a variety of conduits. For example, the closures of both Li and Davidson et al. , include a rigid conduit constructed of a relatively hard plastic that is molded in a fixed configuration. As such, the conduit only provides the necessary elastic interfitting force required for sealing on the neck of the container, so that a cap is not required to improve the seal of the conduit / neck of the container and can therefore be completely removed from the neck of the container. container. Other more flexible conduits present additional sealing problems beyond those solved by the closures of Simón, Davidson et al and Li. Upon considering the Davidson et al. Patent in more detail, the illustrations in Figure 7 and Figure 8 may appear to have some similarity to the present invention due in part to the arrangement of the components in relation to the neck of the container. Additionally, the specification makes mention of a relief 113 or sealing protrusion which is provided in the upper end portion of the outer peripheral surface of the cylindrical wall 106. However, there are several significant differences between the dispenser and dispenser packaging described in the Davidson et al. Patent. , and the present invention. First, the present invention is directed to an assembly that adjusts by pressure of a duct type closure on an enhanced cylindrical neck of a plastic container .. Unlike Davidson et al., The present invention is not threadedly installed with the outer cover over the neck finish. The inner surface of the neck finish is a straight cylinder, without any modification or conformation. Unlike the present invention, the Davidson et al. Package does not include a spreadable or retractable and spreadable delivery duct with a central portion externally threaded so as to receive a screw cap. In addition, the packing of Davidson et al., Does not include an outer ring which snaps onto the outer flange of the conduit which in turn snaps onto the raised neck finish of the container. The packaging of Davidson et al., Seems to be designed specifically for a disposable packaging for a product of a company. In contrast, the present invention solves the need for a press-fit closure assembly which may be suitable for use with a variety of containers from different manufacturers. To some extent, flexible dispensing ducts that move between a snap-on position and an extended position are more susceptible to leakage at the container conduit / neck interface as compared to rigid conduits. As a result, flexible conduits usually require additional means to maintain the seal between the conduit / neck of the container when the conduit lid is removed. See, for example, European patent application number EPO 0 320 808, A1, which describes a conduit having a U-shaped flange received flexibly on a conical container flange and a retaining ring received in a manner Flexible on the conduit. The duct is assembled on the neck of the container before the assembly of the lid. A drawback of this configuration is that the sequential assembly potentially leaves the content of the container accessible to misuse or contamination. If the cap and the conduit are assembled together, too much force is required to assemble the cap and conduit over the flange of the container since both the U-shaped flange and the conduit, and the cap ring must flex in an elastic manner on the same flange of the container. If the lid and the duct are constructed of a less elastic plastic to facilitate simultaneous assembly, the assembled lid and duct are more susceptible to high internal container pressure leaks. Another drawback with other plastic closures are which attempt to establish a liquid-tight interface is its tendency to rotate or in relation to the opening of the container. This probably occurs when the closure cap is screwed back onto the spout and fixed in position. The torque to tighten may be sufficient to overcome the "grip" of the closure on the container opening and thus allow relative rotation between the two. Even if this relative rotation does not actually result in or a significant leak, is negative from the perspective of the consumer because it considers that such movement indicates a probability of flight. Therefore, there is a need for an improved closure for a sealed receiver on a container neck that overcomes the deficiencies of the closures described in the foregoing. Such a closure should provide improved sealing characteristics for high internal container pressures, for example those that are generated by impact or container drops, and yet should be kept easily assembled together with the neck of the container. Preferably, the closure should be constructed completely of plastic and should be easily molded, to facilitate its manufacture. The closure must indicate misuse and must also be installed easily on the neck of a container without risk of damage to the medium that indicates improper use. During the last year there has been a push towards designs in this general field of technology which are economically responsible. Users of closure products often express a desire for design that can be recycled. For example, ducts that are completely plastic in containers that are completely plastic or completely metal have become the designs of choice. After reviewing the existing designs, it has been learned by the present inventors that stricter tolerances are required for particular container opening designs. It has also been found that existing manufacturers of these containers usually use different tool designs and different processes to generate container openings which are designed to receive a closure conduit. This has led to several different configurations now in the market for the same basic opening design. Ideally, a closure conduit designed for a particular opening design should be suitable for proper fit and assembly with any of the different configurations which may be presented on the market. To date, there have been no problems because the current designs incorporate a metal clamping ring which generates the necessary seal. However, many users would prefer to have a completely plastic conduit / closure assembly with the benefits and advantages of recycling mentioned above. A design that is completely made of plastic makes recycling easier and this becomes more important as companies are more sensitive to ecological issues. The present invention provides a combination of conduit and cap indicators of misuse, entirely of plastic, which meets the current needs of the market in a novel and inconspicuous manner. A unique sealing configuration allows the cap and duct to be preassembled and then snapped onto the neck finish of the container. The combination is suitable for container necks which have a smaller shape and tolerance variations.

M ni TA MmAT.-man PREFERRED For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the modality illustrated in the drawings and a specific language will be used to describe the same. However, it should be understood that no limitation is sought in the scope of the invention, since such alterations and further modifications in the illustrated device, and additional applications of the principles of the invention, as illustrated herein, are contemplated as which usually occurs to an expert in the art with which the invention relates. Referring to Figure 1, a plastic container 20 is illustrated which includes an "outlet" opening 21 fitted with a fully plastic closure 22. In the preferred embodiment, the container 20 is a 5 gallon (19 liter) canister. The closure 22 includes a snap-in channel 23 that has a snap-fit assembly over the raised neck finish, which defines the exit opening 21. The closure 22 (see Figs. 2 and 3) also includes a screw cap 24 which initially is integrally attached to a surrounding outer ring 25 by an indicator arrangement of misuse. The conduit 23 includes an inner cylindrical wall which is externally threaded, while the lid 24 includes a cylindrical outer wall 27 which is internally threaded. In this way, the lid 24 is capable of being threaded on the spout channel 23 to close the channel and to be unhooked from the channel when access to the contents of the container is desired. The outer ring radially outward and surrounding fits on a radially outer portion of the channel 23 which in turn attaches to the raised neck finish defining the exit opening 21. A pair of handles 24a and 24b of the drum, positioned opposite each other, are rotatably articulated to the lid 24 and in turn each handle of the drum is connected to the corresponding inner edge of the outer ring 25 by a corresponding series of fragile elements 28. The series 28a connects the handle 24a of the drum with the outer ring 25 and the series 28b connects the handle 24b of the drum with the outer ring. Each handle 24a and 24b of the drum includes a radially extending, centered lifting tab 26a and 26b, respectively, and an outer ring 25 is slotted in two opposite disposed positions, 25a and 25b, which provides a clearance for the two barrel handle lifting lugs 26a and 26b, respectively. The lifting tabs circumferentially saturated in their corresponding series of fragile elements.

Referring more specifically to Figures 2 and 3, the closure 22 is an annular assembly of all-plastic components which makes the design generally attractive from the perspective of reuse or recycling. of hollow central tube, generally cylindrical, which is initially closed by an outwardly tearing diaphragm 30. The diaphragm 30 is placed on the inner surface 31 of the portion 29 by a thin circumferential network 32. The pull ring 33 is used. for cutting the mesh 32, whereby the diaphragm 30 is allowed to be removed and discarded The outer surface of the portion 29 is threaded externally for the threaded reception of the outer wall 27, as previously described. , once the diaphragm 30 has been removed, it is able to access the content of the container 20. In order to control the supply of the content and to avoid With the contamination therewith, the removable lid 24 is applied to close the center portion 29. The conduit 23 includes an annular outer wall portion 36 which, in the engaged or retracted orientation of Figure 2, extends upwardly and outwardly in the fastening flange 37. The conduit 23 is of unitary construction and includes a first reversible fold 38, placed between the wall 36 and the portion 29, and a second reversible fold 39, placed between the wall 36 and the flange 37. two folds that can be inverted allow the spout 23 to extend in a pouring orientation which is known in the relevant art and subsequently return to the engaged or retracted orientation. The attachment flange 37 snaps on and around the raised neck finish, which defines the exit opening 21 with a secure, liquid-tight fit. The flange 37 includes an inner annular wall 40 and radially spaced therefrom an annular outer wall 41. The connecting wall 42 in combination with the walls 40 and 41 define an inverted annular channel 44 which receives the raised cylindrical wall 43. The wall 43 represents the raised neck finish of the container 20, which defines the exit opening 21. The connection of the outer ring 25 to the two handles 24a and 24b of the drum by a series of fragile elements 28 is the reason why the ring 25 can be considered an indicator ring of misuse. In order to open the lid 24, it is necessary to unscrew it and this can be done either in the fitted or extended position of the conduit 23. Since there is a tight interference fit of the outer ring 25 on the fixing flange 37 and in turn an interlock assembly on the wall 43 can not rotate the lid 24 or lift the conduit 23 without first breaking the fragile elements. Therefore, this provides a visual indication of any possible misuse attempt in relation to the closure 22. Once the fragile elements 28 are broken, the drum handles are ready to rotate upwards and are then used to extend the conduit 23. Even after the fragile elements 28 are broken, the outer ring 25 remains fixed hermetically on and around the flange 37 and the wall 43 to help maintain the liquid tight seal requirement. Figure 3 provides a top plan view of the assembly of Figure 2 and illustrates more clearly the shape and location of the handles 24a and 24b of the canister, and the two series 28a and 28b of fragile elements 28. The view in the section of figure 2 is taken along line 2-2 in the direction of the arrows. Careful review of the illustrations in Figure 2 and Figure 3 will also indicate the position and placement of the lifting tabs 26a and 26b with the fingers associated with the handles 24a and 24b of the canister. It will also be noted that the outer ring 25 is grooved in two positions 25a and 25b and that the lifting tabs by the fingers are placed in these grooves. There is a free space that is left under each "lifting tab with the fingers or with the fingernail to insert them in order to lift the handle of the drum The annular and substantially concentric arrangement of the outer ring 25, lid 24 and the combined drum handles 24a and 24b are best illustrated in figure 3. With reference to figures 4 and 5, the outlet opening 21 and the surrounding annular wall 43, which define the opening 21, they are illustrated in more detail. The wall 43 is a unitary, molded extension of the contained end 51 and extends axially for approximately 0.81 cm (0.32 inches). The substantially cylindrical inner surface 52 is a smooth surface and the upper surface 53 is substantially planar. The surface 52 is the primary sealing area for the conduit 23 and defines the substantially cylindrical outlet opening 21. The adjacent upper edge 54 extends radially, the cantilevered rim 55 having a rounded outer surface. The recessed area 56 is positioned below and inwardly of the rim 55 and is located axially between the rim 55 and the end 51 of the container. With reference to Figures 6 and 7, conduit 23 is illustrated in greater detail. Although the drawing of Figure 7 is virtually identical to the drawing of Figure 2, the lid 24, the outer ring 25 'and the outlet opening 21 (including the wall 43), have all been removed. This simplification of the drawing allows some of the characteristics of the conduit 23 to be more clearly illustrated, including the specific geometry of the fixing projection 37 and the shape of the inner and outer walls 40 and 41, as well as their cooperating relationship. The lower portion of the portion 29, which is that region below the diaphragm 30, includes a series of stiffening reinforcements 59, uniformly spaced apart. This conduit 23 can also be provided with a self-venting characteristics designed and configured according to U.S. Patent No. 4,618,078 (and its re-examination certificate Bl), which was granted on October 21, 1986 for Martin E. Hamman et al. ', and patent which is expressly incorporated as reference in its full description in the present. This self-ventilating feature is an optional feature and does not alter the main focus of the present invention which is directed to the fixing projection 37 and the mounting of the projection 37 on the wall 43 and the assembly of the outer ring 25 on the projection 37. As described, the annular wall 43 fits in the inverted channel 44. Since the walls 40, 41 and 42 establish a sealed interface against the wall 43, the specific geometry of the interior surfaces of the walls 40, 41 and 42 is important. Referring now to Figures 8 and 9, the wall 40 The interior includes a first surface 62 which is oriented towards the portion 36 of the outer wall and opposite thereto to a second surface 63 which is oriented towards the inverted channel 44. The lower tip 40a of the wall 40 has a tapered (conical) shape and an annular inclined surface 40b, which provides a secure and convenient introduction to the exit opening 21. This tapered shape provides a smaller inlet diameter for the wall 40 and prevents any stop interference between the wall 40 and the outlet opening. The surface 63 is formed with two separate annular flanges 64 and 65. In the side section, each annular flange has the appearance of being partly circular with a point 66 and 67 projecting outward centered, respectively. The partly circular shape of each flange 64 and 65 extends radially outward, and the portion 68 recessed between the two flanges is curved and has continuous transitions between the flanges 64 and 65. The annular portion 69 is substantially cylindrical and is substantially parallel (ie, concentric, to the annular portion 70 placed on the outer wall 41.

The outer wall 41 includes a substantially cylindrical outer surface 74 which extends axially downward to the corner 75. The lower annular surface 76 is flat and substantially perpendicular to the surface 74. The flange 77, which has a rounded shape in the lateral section extends radially inward towards the flange 65. The innermost edge of the flange 77 is circular and its geometric center is located on the horizontal line 78, which intersects the geometric center of the tip 67. The upper surface 81 of the wall 41 is substantially planar and substantially perpendicular to the outer surface 74. The corner 82 between the surface 81 and 74 is bevelled at a 45 degree angle to leave clearance at the corner with the outer ring 25, see figure 9. The connecting wall 42 has a substantially planar upper surface 83 which is substantially parallel with the upper surface 81. The su The lower surface 84 of the wall 42 is substantially parallel to the upper surface 83 with the exception of the annular, angled or inclined sealing flange 85. The sealing flange 85 is inclined downwardly towards the channel 44 and extends radially outward toward the annular portion 70. The upper surface 83 extends radially outward toward the flange 87. A curved recess 88 is placed below the flange 8 - and with uniform transitions towards the upper surface 81. Referring now to Figure 9, the lid 24, the outer ring 25 and the cylindrical wall 43, which define the exit opening 21, have been added to the view of Figure 8. As will be clear from the enlarged details of the drawing of Figure 9, the lid is threadedly received by the portion 29 of the discharge mouth 23. The rim 55 fits in the channel 44 for example on the upper surface.53 which abuts against the flange 85. The curved outermost extension of the flange 55 abuts against the annular portion 70. The interfitting ridge 77 fits under the rim 55 in the recessed area 56 and abuts up against the outer surface 89 of the wall 43. The wall 41 and the ridge 77 are of a smaller size relative to the projection 37 with the to ensure a tight interference fit on the projection 37 and an interfitting arrangement below the rim 55. The inner wall 40 abuts on the top against the cylindrical surface 52 so that the tips 66 and 67 are compressed within the sealing fit against the surface 52. The radial separation distance between the flange 77 and the tip 67 is smaller than the radial width of the wall 43 below the flange 55. As such, there is an interference fit of the wall 43 upwards, within the channel 4. This interference fit, which is observed on both sides of the wall 43, where the ridge 77 makes contact and where the tip 67 makes contact, generates a comprehensive clamping force to improve the liquid tight seal. Since the tip 66 is also compressed against the surface 52, the sealed interface provides a secondary or safety seal, which improves the liquid-tight relationship between the conduit 23 and the wall 43. The stop of the sealing flange 85 against the surface superior 53 provides an additional secondary or safety seal. The sealing flange 85 is provided to accommodate variations in height in the wall 43 and flange 55. The interference fit of the wall 43 above in the channel 44, combined with the interlocking placement of the flange 77 underneath of the flange 55 generates a safety assembly of the conduit 23 on the wall 43. This sealed combination remains intact even with the repeated change of the conduit 23 from an engaged orientation to an extended orientation, and after returning to an engaged orientation. The outer ring 25 completes the assembled combination and includes an annular outer wall 92 which extends axially in a downward direction, inside the flange 93. The flange 93 protrudes inwardly and is fixed below the corner 75. The inner reinforcement 94 is housed in the upper part of the upper surface 81 and therefore, is actually interposed or exerts an action of clamping by the outer ring 25 on the outer wall 41. Once it has been snapped in place on the outer wall 41, the outer ring 25 is fixedly assembled and has no freedom of movement in the axial direction. The outer ring 25 remains fixed by pressure on and around the wall 41 and on the wall 43 even after the fragile elements have been cut and the handles of the drum have been released. The mounting of the outer ring 25 on the wall 41 is important as a means for reinforcing the wall 41 and its snap-fit assembly on the wall 43. Any tendency for the walls 40 and 41 to flex or separate which may loosen their support on the wall 43 is prevented by the outer ring 25. There is no place for the wall 41 to be loose and in this way securely fixed in its position both axially and radially. In actual practice, the combination of cap 24 and outer ring 25 are first assembled to conduit 23. Cap 24 is threaded on wall 31 and outer ring 25 is clamped around wall 41. This assembly is then pushed to a closing position on the wall 43. The snap-fit assembly of the flange 55 on the channel 44 fixes the conduit on the neck finish (wall 43) of the container 20. The present invention uses various novel features and is not very evident. which return to closure 22 particularly appropriate for its proposed application. To begin with, the cylindrical surface 52 of the neck finish wall 43 is also the most uniform and consistent dimension among current manufacturers. The sealing beds which are provided by the tips 66 and 67 are specifically designed with a snap fit against a cylindrical surface 52. The various portions of the flange 37 are dimensioned so as to produce an interference fit against the surface 52, even if the surface 52 is of a size larger than expected. The specific thickness and size of the wall 41 are selected in order to provide a dough that provides rigidity for the tips 66 and 67, to press fit with stiffness and seal the interface. The thicker wall provided with the inner wall 40 results in a collar or ring of improved strength for that wall, by which it tends to keep the tips 66 and 67 in fluid-tight contact and compressed against the surface 52. The sealing bed ( point 67) is located on the same horizontal line 78 as the flange 77 and is of a greater or increased wall thickness compared to the wall 40. This is a unique arrangement and helps ensure that the compressive force of the tip 67 against the surface 52. The flange 77 provides a mechanical fixation and is dimensioned so that it has a smaller size in order to generate, by the way, a clamping force, and as a result an improved seal. This particular design allows a variable thickness with the wall 43, thereby allowing the present invention to be suitable for use with containers which can be produced with different manufacturing methods by different manufacturers. With respect to other possible dimensional variations, the axial height of the wall 43 and in particular the axial thickness of the flange 55 may vary between manufacturers and between different manufacturing methods. For this reason, the sealing flange 85 has been provided on the lower surface of the connecting wall 42. Although the invention has been illustrated and described in detail in the drawings and preceding description, it is considered as illustrative and not as limiting in character, it being understood that only the preferred embodiment has been shown and described., and that it is desired to protect all changes and modifications that are within the spirit of the invention.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
