Definitions
- This invention relates to plastic containers, and in particular, to lids for such containers where the lids have tear-off strips to facilitate the removal of the lids.
- One method of accomplishing the above objectives is to provide the lid with a tear-off strip that contains the lid locking flange that engages the container locking flange.
- the engaged locking flanges hold the lid securely onto the container.
- the lid tear-off strip is removed, so there is no longer any locking engagement between the lid and the container. The lid is then easy to remove.
- a lid according to the preamble of claim 1 is disclosed in FR-A-2 103 410.
- a double locking flange is provided to securely hold the lid on the container.
- One of the locking flanges is totally removed along with the tear-off strip leaving a second, intermittent yieldable locking flange for retention and resealing of the lid on the container.
- a lid for a container having upper and lower peripheral, outwardly disposed locking flanges, the flanges having undersides for locking engagement with the container lid.
- the lid comprises a central portion and a peripheral annular skirt adapted to overlie the container locking flanges.
- the annular skirt defines a peripheral groove dividing the skirt into a skirt upper portion located adjacent to the container upper locking flange, and a lower tear-off strip portion located adjacent to the container lower locking flange.
- the skirt upper portion has inwardly disposed intermittent locking flange segments adapted to engage the underside of the container upper locking flange.
- the skirt upper portion also is formed with thin membrane windows therein on either side of the locking flange segments and bordering on the peripheral groove.
- the tear-off strip portion defines an inwardly disposed locking flange adapted to engage the underside of the container lower locking flange, so that removal of the tear-off strip portion leaves downwardly disposed thin membrane notches on either side of the locking flange segments.
- a lid providing, after removal of the tear-off strip, similar resilient lift-off segments is disclosed in EP-A-0 052 172.
- the notches disclosed therein delimit the resilient segments, but are primarily designed to be penetrated by locking projections provided on the container which are clamped against the upper surface of the tear-off strip.
- a preferred embodiment of a container lid according to the present invention is generally located by reference numeral 10.
- Lid 10 is shown mounted on a container 12, but container 12 is not considered to be part of the present invention per se.
- Lid 10 includes a planar central portion 14 and a peripheral annular skirt 16.
- the size of container 12 is such that it holds typically from about 4 to 20 litres, and container 12 and lid 14 are most commonly made from plastic, such as polyethylene or polypropylene.
- any plastic or other material can be used for lid 10 that has some resiliency, as will be described further below.
- container 12 having an upper, peripheral, annular, outwardly disposed locking flange 18 and a lower, annular, outwardly disposed locking flange 20 spaced from or below locking flange 18.
- Locking flanges 18, 20 have respective undersides 22, 24 for locking engagement with lid 10, as described further below.
- Container 12 also has a further peripheral annular flange 26 which forms the rim or brim of container 12, and which is located in an annular sealing groove 28 in lid 10 located between the lid central portion 14 and the peripheral annular skirt 16.
- the container annular flange 26 is wedged into lid sealing groove 28 to provide a good seal between the container and the lid.
- sealing groove 28 sealingly engages the rim 26 of the container.
- a gasket (not shown) can be used in groove 28, or groove 28 can be smaller than that shown in the drawings.
- Annular skirt 16 overlies the container locking flanges 18, 20, Annular skirt 16 defines or has an annular groove 30 which divides skirt 16 into a skirt upper portion 32 located adjacent to the container upper locking flange 18, and a lower tear-off strip portion 34 located adjacent to the container lower locking flange 20.
- Annular groove 30 can be on the inside surface of annular skirt 16 or the outside surface of this skirt, or partially in both, as shown in Figure 3.
- the skirt upper portion 32 is formed with inwardly disposed intermittent locking flange segments 36 which are adapted to engage the underside 22 of the container upper locking flange 18.
- the tear-off strip portion 34 defines or has an inwardly disposed locking flange 38 which is adapted to engage the underside 24 of the container lower locking flange 20.
- skirt upper portion 32 is formed with triangularly shaped thin membrane windows 40 therein on either side of the locking flange segments 36.
- Windows 40 border on the annular groove 30, so that upon removal of tear-off strip portion 34, as will be described below, windows 40 turn into downwardly disposed V-shaped, weakened areas on either side of the locking flange segments 36.
- the part of skirt or upper portion 32 located between windows 40 that contains locking flange segments 36 thus becomes a flap 42 that can be pried outwardly and upwardly to release the locking flange segments 36 from container upper locking flange 18 and thus allow for the easy removal of lid 10 from container 12.
- the thin membrane windows can tear as flaps 42 are pried upwardly, or, if windows 40 are made thicker, they can stretch elastically and act as springs to help return flaps 42 to the locking position.
- the membranes of windows 40 typically are about .2 to .5 mm (0.008 to 0.020 inches) thick, and prevent dirt or other foreign matter from entering windows 40 and collecting on flange 20.
- membrane windows 40 can have strengthening or reinforcing ribs 43, especially if it is desired that the membranes not tear upon the lifting of flaps 42. With ribs 43, flaps 42 will more readily resume their original shape after being lifted.
- a modified membrane window 45 is shown where the membranes have openings 47 therethrough bordering on the annular groove 30.
- the removal of tear-off strip portion 34 thus leaves downwardly disposed open, inverted V-shaped open notches on either side of the locking flange segments 36 to make the lifting of flaps 42 easier.
- the openings or notches 47 can be any shape or configuration desired, even narrow vertical slits, if it is desired to prevent dirt or debris from passing through windows 45.
- tear-off strip portion 34 is formed with a window 44 located adjacent to annular groove 30.
- window 44 could have a thin wall or membrane covering to keep dirt out, or it could be an actual opening formed in tear-off strip portion 34.
- Tear-off strip portion 34 has a lower peripheral edge 46, and tear-off strip portion 34 is formed with a reduced thickness portion 48 located between window 44 and lower peripheral edge 46.
- a tool such as a screwdriver into window 44 and pry the tear-off strip portion 34 outwardly to break reduced thickness portion 48. This provides a flap or tab 50 that can be grasped and pulled outwardly to tear the tear-off strip portion 34 along groove 30 to remove tear-off strip portion 34.
- tear-off strip 34 also removes the locking flange or flanges 38, leaving only the intermittent locking flange segments 36 to engage the container. This permits lid 10 to be removed easily by prying up flaps 42, yet the intermittent locking flange segment 36 permit lid 10 to be placed again on container 12 with good sealing engagement between the container rim or annular flange 26 and lid sealing groove 28. It will also be appreciated that breaking reduced thickness portion 48, and perhaps window 44, is a tamper evidence feature for lid 10.
- lid 10 is provided with 4 equally-spaced intermittent locking flange segments 36 on the skirt upper portion 32.
- tear-off strip portion 34 has an inwardly disposed locking flange 38 that is a continuous annular flange located around the inside of tear-off strip portion 34.
- Locking flange 38 passes over the reduced thickness portion 48, and depending on the thickness of locking flange 38, it may be necessary to insert a knife into window 44 and cut downwardly through locking flange 38 and reduced thickness portion 48 in order to break out tab 50 in this embodiment.
- FIG. 9 there are only two diametrically opposed locking flange segments 36 on the inside of skirt upper portion 32.
- tear-off strip portion 34 has a pair of semi-circular and inwardly disposed locking flanges or flange segments 38 rather than a continuous locking flange 38.
- the Figure 9 embodiment is useful for smaller containers where the lids need not be held so securely on containers 12.
- the Figure 8 embodiment is useful for larger containers where stronger retention between the lid and the container is desired.
- locking flange segments 36 could be located between all of the pairs of openings 40 to make an even stronger connection between the lid and the container.
- the size and the length and the number of locking flanges 36 and 3 8 can be configured as desired to give the necessary shipping strength to the container and lid combination of the present invention, or to provide for easier or more difficult removal and reinstallation of lid 10 for the re-use of container 12.
- FIGS 10A to 10C are embodiments of the lid of the invention in which the outer surface of the skirt upper portion 32 corresponding to the position of the intermittent locking flange segment 36 includes indicator means on the outer surface, indicating to the user where to lift the flaps 42 when removing the lid 10 from the container, after the tear-off strip 34 has been removed.
- Shown in Figure 10A is an embodiment including the features of the lid of Figure 9 and further including indicator means comprises a recessed portion 52 which includes arrows pointing upwardly 54. The recessed portion and arrows indicate to the user where the intermittent locking flange 36 is located and thus where to lift the flap to disengage the lid from the upper outwardly disposed flange 18 of the container.
- FIG. 10B and 10C Shown in Figure 10B and 10C are embodiments with variations in the indicator means, namely in Figure 10B a pattern of protrusions 56 are present in the recessed portion 52 and in Figure 10C a high gloss patterned surface 58 are present in the recessed portion, indicating the position of the locking flange segments 36 and thereby where to lift the flaps 42.
- the recessed portion 52 in any of these embodiments may have a matted or textured surface.
- the thin membrane windows 40 of the embodiments shown in Figures 10A to 10C may include strengthening ribs 43, such as those shown in Figures 5 and 6. Such windows may be modified in the manner shown in Figure 7.
- the lid and container of the invention may be rectangular or square in circumference. Examples of square lid embodiments are shown in Figures 11 to 12.
- the square lids preferably include the features as described in the embodiments above and illustrated in the Figures herein and may be utilized in essentially the same manner.
- an embodiment of the lid 10 is provided with four intermittent locking flange segments 36 on the skirt upper portion 32, one on each side of the square for engaging the outwardly disposed locking flange 18 of the container.
- a tear off strip portion 34 has an inwardly disposed locking flange 38 present on each side of the square. This inwardly disposed locking flange 38 may be interrupted at each comer 60 of the square.
- the tear off strip portion 34 includes a reduced thickness portion 48 with a window 44 created when tab 50 is engaged with the skirt upper portion 32.
- the locking flange 38 passes over the reduced thickness portion and depending on the thickness of the flange, it may be necessary to cut through the locking flange and reduced thickness portion in order to break out tab 50.
- Figure 11 shows tab 50 broken out of engagement with the skirt upper portion 32.
- the locking flange 38 is interrupted at the reduced thickness portion, thereby eliminating the need to cut through the flange 38 and reduced thickness portion 48 with a foreign implement, allowing for easier removal of the tear off strip.
- the embodiment of Figure 11 includes indicator means in the form of a recessed portion 52 with arrows 54 on the skirt upper portion 54 corresponding to each intermittent locking flange 36 segment thereby indicating to the user where to lift the lid when disengaging it from the container.
- the skirt upper portion is formed with thin membrane windows 40 on either side of the upper locking flange segments 36. As discussed above; windows border on the annual groove 30 between the skirt upper portion 32 and tear off strip portion 34 such that upon removal of the tear off strip portion 34 the windows become downwardly disposed V shaped weakened areas, thereby allowing the upper flange segments 36 between the windows 40 to be more easily lifted and released from the container outwardly disposed upper locking flange 18.
- the thin membrane windows on the square shaped lid of the invention described and illustrated herein may have the same features and as those windows and variations thereof as described above and shown in the Figures, including but not limited to Figures 4, 5, 6 and 7.
- the tear off strip portion 34 may include a locking flange 38 extending around the entirety of the lid. Alternately, as discussed above and disclosed in the figures, the tear off strip portion 34 may have several discontinuous locking flange segments 38 extending around the lid. For example, the comers 60 of the square may not include the flange segment 38.
- the embodiment shown in Figure 12 may be utilized for containers where the lids need not be held so securely on containers 12. Since the Figure 11 embodiment include greater means for retention of the lid on the container due to the presence of upper locking flange segments 36 on each side of the square container, the lid of Figure 11 will be useful for containers where stronger retention between the lid and the container is desired.
