JPH06504750A - Pry display closure with retention hoop with relief window - Google Patents

Abstract

A closure (11) for a container (10) has a tamper indicating band (22) with a band retainer (29) in the form of an apertured flap or hoop which is hinged to the lower edge (30) of the band. A series of enclosed, open windows (36) or thin webs (36A) are formed in the retainer, extending toward but not to its distal edge (32). As the retainer is turned inside out from its as molded position to its use position, its distal and/or outer edges deform to relieve compression and permit the retainer to be inverted by direct downward pushing force. As a result of the deformation, the retainer in its use position may, depending on the number and relative size of windows or webs, have an advantageous polygonal peripheral shape rather than a circular shape.

Description

[Detailed description of the invention] Retention hoop with relief window Has a pry-open closure, The present invention provides a visible indication that the container has been opened when broken. The frangible prying device relates to container closures of the type with indicator bands.

Related application This application is filed in the applicant's co-pending U.S. Application No. 568, filed August 20, 1990. , No. 575, and a continuation in part of No. 624,710 filed December 7, 1990. This is an application.

Technical issues Pry-open closures with indicator bands generally have a closure that surrounds the container's neck. Some type of band retention device is included that engages the underside of the chain bead. This horn When the cage is opened for the first time, the "retainer" applies a downward force on the band, The band thereby cuts and separates from the upper part of the closure. So immediately A visible gap is made between the band and the upper part of the closure, and the container and/or closure is at least partially opened; is shown. This retainer is often made of spaced upward facing tabs or bands. It has the shape of a fishing hook surrounding the inside.

To ensure that the display band breaks, pry during the first opening, say Needless to say, when the closure is removed, the retainer snaps onto the closure bead on the container. Reliably engages the bead without sliding upwards and is reliably blocked by it. is important. For this reason, relatively stiff and inflexible retainers are desirable. Delicious. If the retainer is too flexible or flexible, it will prevent it from closing. Collapsed or folded over as it begins to engage the chain bead, thus moving upwards in the band The closure does not resist movement, so no prying will be visible on the band. can be removed without affecting the

However, the forming process requires a "descending" position in which the retainer is bent inward and downward from the top. The retainer is required to be molded in place. The molded retainer in this lowered position If the hole breaks too much, it will cause the initial "unformed" position above to prevented from being turned or folded into its upward, use position where it engages the closing bead. will be stopped.

In some instances, a container with a retainer in the lower, unformed position may be closed. A retainer can be used once the closure is secured in place. Automatically face up or flipped into position for use. However, careless opening Another case where the retainer is stiffer to better prevent downward bending. In some cases, this may be done after the closure has been molded and when the closure is used on the container. A separate post-forming operation is used to turn it up before being used. two The purpose of the factors is at odds, and the lower and unmanufactured positions are so stiff that the retainer becomes stiff. It will be difficult to reverse the position from the upper bead to the position of use, but the position, it engages the closure bead more securely when the closure is removed. match. The retainer is very stiff and joins around its circumference at its internal edges. If it has to be forced upwards by continuously applying instantaneous force, it is usually The large force required slows down the work.

Therefore, from the lower molded position to the upper use position at a rate consistent with high production rates. can be rotated to any position while still ensuring that the band will not break upon opening. A prying device with a retaining device of sufficient stiffness to Exists.

Conventional technology U.S. Pat. No. 4,478,343, FIG. A pry-open closure with a retaining tab and display band is shown. We The tab extends inwardly to the tab.

No. 4,657,153 discloses a spaced-apart device for engaging just below the bead of the container. A closure is shown having a plurality of upwardly facing closure tabs. No. 7 of the above patent In figure A, the hinge 13 at the base of the tab lO is separated by an intermediate slot 14. It is. Each window is several times longer than its respective hinge.

No. 4.796.770 requires circumferential isolation by cutouts to function independently. a closure having a retention device in the form of a plurality of hinged flaps; It is shown.

No. 32,879, a separately protruding stop is used to prevent prying from display bumps. hinged along the lower edge of the band and extending through it into a relief window above the band. Rocks upward and inward to protrude, thereby allowing the cap to slide out when in use. This provides clearance for the top to cam outward.

Brief summary of the invention When the retainer is pried open, there is a continuous, inwardly angled opening below the display band. In general, the shape of a conical hoop without then flip the retainer from the lower, unformed position to the upper bead-engaging position. It is difficult to turn it over when required to do so. According to the present invention , the retainer has a nearly continuous flap around its distal (internal) edge. Or in the form of a hoop. It is attached to the band along its outer edge. a series of “relief windows” or internal deformations spaced along We are prepared. (When used here with respect to the distal edge of the retainer, “continuous” means that the retainer is uninterrupted or has a single gap at its distal edge. This means that only the Like a transverse gap at the distal edge A retainer of another similar closure with unbroken edges It becomes easier to press the retainer onto the closing beat of the container compared to

However, clozes with no splits or only a single split Removing the cap is possible using a clover with multiple splits around its distal edge. It is much more difficult than Ja. ) According to the relief window, the container closure A balance is achieved between the force required to position up and the force that results in an indication of prying. It will be done. They allow the hinged and/or distal edges of the retainer to It can be deformed in an advantageous manner under the compression that occurs during rolling. The retainer is When folded to the upper position, it passes through a plane perpendicular to the central axis of the closure. deforms to relieve compression as it moves. The deformation is bumped in the plane of the retainer. It may be away from the hinge line at the lower edge of the retainer and May appear as arcs perpendicular to the plane, or 'mullions' between windows Buckling may occur near the hinge line in the direction transverse to the plane of the na.

A relief window may be an "open" window, ie, an aperture or hole. Or again, Rather than having an opening through the hoop to reduce the strength of the hoop, use an open window instead. Rather, similar results could be achieved by providing a relatively thin web. It has been discovered. This web, like an open window, also reduces hoop strength. It must be thin enough to reduce the The web is a hoop, like an open window exists within (bordering) the hoop, but does not extend to the internal edges of the hoop. do not have. Similar to an open window, the installation of a thin relief web allows the closure to The hoop can be turned over much more easily prior to its time being secured to the vessel. . A hoop has its inner edge in compression and its outer (hinge) edge from its lower position to its upper position via an intermediate inwardly directed central position in a state of extension. The strength of the hoop is reduced by the web when turned into the normal position, so that the hoop becomes more capacitive. It can be more easily folded for use prior to seating on the vessel. Therefore, non- The restrictive term "window" as used herein refers to open windows and retainer counters. During rolling, both sides of the window are closed by a web so thin that it acts like an open window. is intended to mean and include.

No. 4.478,343, spaced apart discontinuous web-joined For standard band retention devices, it is recommended to install a hoop with an internal relief. stomach. The above patent requires tabs connected by a thin web; Edges are difficult to form evenly on a production scale. The retainer of the present invention , continuously around the closure, i.e. without any "gaps" along its internal edges. , can exist. It can be relatively more intimidating than the separate tabs above, and in fact , thicker at its internal (distal) edge than at its external (hinge) edge but it gives a harder "grip" on the container. This is desirable because it allows

Surprisingly, these windows provide a number of unexpected benefits. window They reduce the time when the closure is secured to the container, compared to non-retainers. The retainer can be folded more easily and quickly prior to. retainer down When turned upward from a vertical position, the window effectively relieves compressive stress. Ma The octopus window increases the force and shear forces required to secure the closure on the container. between the circumferential shear force required to produce a pry indication by A good balance is achieved. The window should preferably be as tall as the retainer (in terms of transverse dimensions). It is desirable to have a “height” of The small distance from the abutment (i.e., hinge edge) to the distal (internal) edge of the retainer It should cover at least 1/3.

The retainer of the present invention can be relatively rigid, preferably with an internal It is desirable that it be thicker at the (distal) edge than at its external (hinge) edge. The window is there If it is narrow relative to the circumferential dimension between them, then (flat in use position) The retainer has a distinct polygonal shape (viewed in top view), in this case the inner part of the hinge A portion presses the container neck more firmly than the inner portion of the window.

This improves the "grip" of the retainer on the container and therefore allows it to be opened. This improves the band separation action when the closure is turned.

An additional advantage is that during use, all internal edges of the retainer are in close contact with the container neck. between the retainer edges and the container wall. If possible, it is desirable that there be no gap at all.

A further advantage is that if the window has a relatively small area or is closed with a web, This allows insects to enter the space between the band above the retainer and the container. This is something that cannot be done. In fact, even the size of the as-molded open window requires that the retainer When folded, the retainer deforms into the window area and may shrink. be. This allows from 0,381mm (0,015') at the closure. It is also possible to follow recommendations for any large gaps.

Part 1: Additionally, this open relief window can be as a drainage boat for wash water directed downwards and/or upwards from a point below; It works. The wash water directed in this way flows over the threads and lugs of the container and These can be cleaned and then drained through an open window in the bottom of the retainer.

detailed description In the drawings, a container 10 is shown with a closure 11 in its top opening. It is. For illustrative purposes, closure 11 includes integrally molded top 12 and skirt. 14 as a one-piece plastic molding.

However, if a metal or composite disc is inserted within the annular plastic shell, It is expected that the principles of the present invention will also be effective for composite closures such as It is.

As used herein, the term "top" in connection with a closure includes an integral top and and a separate top, or the shell or skirt 14 can be integral with the top. or it may be different.

The container lO shown for illustration is in the form of an external thread 16 surrounding its groin. a closure locking device that engages with the internal thread 18 of the closure 11; do.

However, the present invention is applicable not only to threaded containers, but also to intermittent beveled lugs and snap containers. - It should be understood that it is also effective for containers containing beads.

Around the lower edge 20 of the closure skirt 14 is generally designated 22. broken, breakable, or removable pry display bands are attached. . This band 22 is in the form of a ring, which consists of a series of spaced apart frangible bridges. 25 (see Figure 3). has been completed. Bridge 25 is a circumferential notch surrounding the outside of the closure. It may be a line or an interrupted portion of the partial cut 27. in these bridges Otherwise, band 22 is separated from the rest of the closure by score line 27. It will be done. Therefore, the bridge 25 must be opened so that the indicator band 22 is in the upper part of the closure. Acts as a "weak link" that detaches or tears along it from the base. (The fruit shown is In this embodiment, the band 22 is completely removed from the remainder of the closure when the bridge 25 ruptures. It completely separates and then remains on the container. Alternatively, it is shown as a dotted line in Figure 7. After the band 22 is torn along the break line and the bridge 25 is damaged, the The flexible connector remains attached to the closure and the band therefore remains capacitive. It is also possible that it may be removed with the closure without remaining on the vessel. ) Figure 2 and As shown in detail in FIG. in the form of continuous hoops or flaps connected together along the lower edges 30 of 2. A band retainer or retainer 29 is included. (The flap is at one point around the circumference of the body, at its internal or distal edge 32, as shown at 28 in FIG. It is also possible to have a "split", gap or partition, such as Not desirable. ) The retainer 29 extends downwardly and inwardly from the skirt 14; That is, it is molded in a first position (see FIG. 3) where it is angled away from the top 12. No. As shown in detail in Figure 2, the retainer is preferably Therefore, it is thicker at its internal edge 32 than at its hinge edge 35. It is desirable that it be tapered so that it becomes.

The retainer 29 is secured by a series of spaced apart flexible integrally molded hinges 34 that prevent it from being pried open. are hingedly connected to the display bands 22, preferably each with a retail act as an arcuate joint when the hinge is folded around the hinge edge 35. Sufficient angular range to provide over-center hinge action is desirable.

The hinge 34 is separated by a relief window or deformed portion 36, as shown in FIG. separated from each other.

The window 36 should have an external edge colinear with the hinge 34 along the edge 35. A rectangle with . In the preferred embodiment shown, the window 36 is of considerable height. (dimensions in the direction towards the distal edge of the hinge) and they extend from the hinge edge extending at least 1/3 of the distance to the distal edge, in other words above the window. The non-opening portion of is less than 273 of the height of the flap. But anyway, window 36 does not reach the distal edge 32, i.e. the split as at 28 is probably different. As the distal edge 32 is continuous across both the window 36 and the hinge, the distal edge 32 is continuous and broken. It is important that there is no such thing. Window 36 is open (as shown in Figures 2A and 7A) They may be apertures or they may be thin webs. They are Narube If so, it is desired to begin at hinge line 35 and extend toward distal edge 32. Delicious. The closer the windows 36 extend to the edges 32, the more they hold the retainer. The closer the hoop is cut, the lower the hoop strength will be. (open or with web) window 36 is located If too large for a given closure and material, the retainer 29 will the band becomes too weak to slide through the band 40 and the band separates at the score line 27. There is a risk that it will not work. If webs are provided, they will probably have a thickness of about 0 ．． Compared to a 635 to 1.525 mm (0.025 to 0.060') hoop, Membrane or film thickness, for example from about 0.254 to 0.508 mm (0.01 0 to 0.020'). If the web becomes like this, it will be shown in Figure 2A. Preferably, it is coextensive with the top surface of hoop 29 as shown, or It may also be located on another (lower) surface. In this example, the "mari" between the windows 44 and the hinge has a circumferential extent wider than the window and the size of the closure Depending on the size, they can be significantly wider (eg 1.5 to 6 times) wider than the window 36.

In this embodiment, the circumferential width of the window 36 preferably corresponds to the diameter of the cap 11. Accordingly, at least twice their height is desirable. Distal of the window, as shown in Figure 2. The edges can be beveled downward to facilitate removal from the mold.

The closure shell can be molded and, if used, the web - it These are molded thinner than the retainer in which they are presented. As shown in Figure 2 and Figure 2A. The interior edges of window 36 and web 36A facilitate removal of the closure from the mold. It can be tilted downward to make it easier.

As already indicated, these windows 36 allow the retainer 29 to remain in its unmolded position. (FIG. 3), it should be held directly below the closure bead 40 of the container 10 (inner edge 32). be surprised when it is flipped into the use position shown in Figures 2 and 6. You can get a good effect. The retainer 29 is a truncated cone with a circular distal edge 32. 2, so that it assumes a circular shape after being folded into the use position shown in Figure 2. , it is also conceivable that the two positions are symmetrical about the plane passing through the hinge line 35. It will be done. But that will never happen. On the other hand, the retainer in use is As seen in the plan view, it has a generally polygonal shape. The shape of this polygon is It stands out the most among the relatively few closures with small windows.

More specifically, the applicant has proposed that the provision of the relief portion 36 prevents deformation of the retainer. This allows the distal It has been found that the compression conditions that occur along edge 32 are reduced. Fruit of Figure 2 In embodiments, the distal edge 32 is radially deformed to lateralize the window (between the hinges). Shape an arc or peak that extends outward (perpendicular to the plane of the retainer) in the area to be cut. to be accomplished. When the retainer 29 is folded into the upper position in FIG. This is not a circular shape, but rather takes the form of a polygon as shown in FIG. portions of the retainer (i.e., across window 36) are deformed radially outward, thereby The distance between the band and the distal edge 32 of the retainer is reduced and the hinge between the windows 36 A portion or mullion 44 is located closer to the central axis of the closure. this shape Due to this, the retainer 29 is made with respect to manufacturing tolerances of the dimensions of the container lO and the closure 11. Still, it grips the side wall of the container directly below the closure band 40 better and more securely. The display band can be separated by shearing and prying the bridge 25 apart.

Retainer 29 typically fits relatively tightly around the entire circumference of the container. And it acts as a seal against insect damage. This fit must be extremely tight. 0.381 between the distal edge 32 of the retainer and the container wall. There are no openings exceeding the maximum recommended limit of mm (0,015'). Aperture Even if the window 36 itself is partially closed due to the deformation of the retainer 29, The gap above them is probably <0.381mm (0.015”) by itself less than (The web generally closes the window.) Additionally, the retainer distal edge 3 The distance from the line of contact with the container of No. 2 to the bottom 34 of the closure is determined by federal FSIS regulations. According to the rule, it will probably be <3.175 mm (1/8') or less. This results in , the possible suction of dirt and contaminants into the container when the vacuum is interrupted is avoided. be done.

In addition to reducing hoop strength when the retainer is inverted to the use position, The opening also facilitates flushing between the intermediate unscrewing chamber between the closure 11 and the container lO. Let it be. For example, downwardly through the water slot in the closure 11 above it and and/or a water spray directed upwards toward the distal edge 32 to remove lugs and breaks. Flush between the threads to clean them and then remove any entrained food grains. Water can be drained downward into a V-shaped pocket 48 that carries the child and flushes out through the window 36. can.

In the embodiment shown in FIGS. 1-6 and described above, the window 36 is relatively few and narrow relative to the width of the hinge mullions 44 between them. already As shown, the above embodiments provide a relatively rigid retainer. young In the case of drying applications, it is not necessary to have as high a rigidity as on the left, and it is possible to further increase the window area ratio. I can do it.

This also reduces the area of the pocket 48 between the retainer and the band, making it more A larger opening area is provided for better flushing and drainage. progressively larger Embodiments with windows are shown in FIGS. 7, 8, 9 and 10, respectively. ing.

In the embodiment of FIGS. 7 and 8, the hinge mullion 44 between them and The widths (circumferential dimensions) are almost equal. In this example, as in the beginning, The upper portion of the window 36 is connected to the band 2 as shown by the arrow 45 in FIGS. 6 and 12. 2, but each deformation has more windows, so few. In the upper position the retainer previously formed a polygon, but peak 4 2 is much less pronounced (see Figure 8). They are e.g. Detect as non-uniformity by running your finger around the internal edges of the be able to.

If the window 36 is of greater width and/or height, i.e., as shown in FIGS. If wider than the hinge, as in the illustrated embodiment, the retainer 29 will fit across the window. , further deflecting along its internal edges to otherwise relieve the compressive stress.

In this case the distortion is in a direction different from the lateral distortion shown in Figures 6 and 8 ( (insufficiently deformed) in the plane of the original band. For this example, the deformation is moving away from the hinge edge 35, as indicated by the arrow 55. parallel to the mullion 44 rather than radially, and the distal edge 32 has a "wavy" undulation. It has a shape with a certain height or height (see Figure 1O). In this example, yen Circumferentially narrow hinges can no longer function as arc hinges; bend along a short, almost straight line. This configuration is suitable for small diameter closures. Moreover, the wavy edges are effective for Interfitting with flexible ribs ensures even more rapid rupture during turning. The window is , should be opened for this kind of deformation to occur and the web constrains it .

Further variations of the various types of retainers are shown in FIGS. 11 and 12. downward In the position, the inner diameter of the retainer measured at its innermost edge is displayed as 50. Ru.

In the upper position (phantom line 52) it has approximately the same inner diameter 50. retainer 29 moves through the over-center (horizontal) position, halfway between the lower and upper positions Although its inner diameter remains the same, the retainer does not deform to allow this. The distal edge 32 must therefore be placed in compression. relative window size Depending on the size and other factors, the distal edge may be located at 54 in the plane of retainer 29. upwardly and inwardly as at , or perpendicular to that plane as at 42 Alternatively, the hinge mullion may be deformed, as at 58 in FIG. It can also be buckled from the plane. In each case, the deformation is the edge 32.3 transverse to the (undeformed) original arc of 5. Deformation is due to retainer It occurs when the retainer crosses the heart, but tends to remain even after the retainer reaches the upper position. Ru. In each case, adjustment of the compressive stress allows the retainer to be By simultaneously applying a straight axial force across the can be set. The retainer is moved progressively around the edges to "wrap" the retainer. need not be forced upwards by applying a local force to . ``Thus, Considerable time is saved on the production line.
