Definitions
- Notches in the ring serve to furnish an anti-locking feature for stacking as well as provide an anti-sloshing feature to the ring when the lid is used as a coaster.
- the skirt of the snap-on lid has an inner elongated arcuate shaped land to provide a nesting and anti-shift feature to the detent means of the snap-on lid.
- a primary object of the invention is to provide a novel plastic cover having detent means for holding the plastic cover onto the bead about the upper edge of the container.
- Another object of our invention is to provide a lid having notches in a raised annular ring for stacking and having a skirt and peripheral channel which dovetail one on the other so as to avoid lateral shifting and sticking of stacked lids.
- FIG. 1 shows a perspective view of a container provided with a cover formed in accordance with our invention
- FIG. 2 shows an enlarged fragmentary vertical sectional view taken along the section line 22 of FIG. 1;
- FIG. 3 shows an enlarged fragmentary vertical sectional view similar to the view of FIG. 2 but showing a cover in the process of being seated onto or lifted from the container bead;
- FIG. 4 is a plan view of the cover showing a first type of detent lug
- FIG. 5 shows a cross-sectional view of the lid skirt taken along the line 5-5 of FIG. 2;
- FIG. 6 is a plan view of the cover showing a second type of detent lug
- FIG. 7 shows a vertical cross-sectional view of a stack of snap-on covers of this invention.
- FIG. 8 shows an enlarged fragmentary vertical sectional view similar to FIG. 2 of a second embodiment of our invention.
- This invention relates to plastic covers or lids which are adapted for use with containers having a bead about the upper edge of the container.
- a combination of lid 1 and container 2 is shown in FIG. 1.
- the container in FIG. 1 may be a paper, plastic or plastic covered paper drinking cup or the like having an external bead around its upper margin.
- the cover or lid 1 of the invention is mounted hereon. Any container 2 that has a bead around its upper edge may have the lid fitted over it in a fashion similar to that shown in FIGS. 1 and 2.
- the drinking cup or whatever container used requires a suitable size lid to fit snugly over its upper rim.
- the cup or container is of a conventional known structure and it is understood that any such structure having a bead 3 around its edge may be used with the lid of our invention.
- FIG. 1 shows a perspective view of the lid 1 in place on a container 2 of some sort
- a more detailed showing of the construction of the outer margin of our invention with its snap-on lid 1 is shown in FIG. 2.
- the plastic cover is shown snapped on over the container bead.
- This container bead 3 may be an annular roll 4 located around the top of the container and is of a more or less uniform thickness around the top of the container.
- the cover in FIG. 1 is snapped onto the container. It has a depending peripheral generally cylindrical skirt 5 located around its outer margin to form a garter spring structure.
- the depending peripheral skirt extends downward from the margin of the central panel 6 or top wall of the lid and an inverted peripheral channel 7 connects top wall 6 to the peripheral skirt 5.
- the inverted peripheral channel 7 has a circumferentially spaced generally vertically arranged shaped extensions 8 formed at the lower wall portion of channel 7 to form a waist 9 on the lower inner wall of the inverted peripheral channel.
- the waist 9 (FIG. 2) is formed by the extensions and a lower elongated arcuate inner surface or land 10 is arranged below each extension.
- the waist acts as a detent structure made up of a series of retention lugs.
- the elongated arcuate inner surface 10 acts as a land for guiding the container bead into and out of the inverted channel 7.
- the upper part of the elongated arcuate surface forms a shoulder 11 on the land 10.
- the waist 9 provides for a snug fit of the lid or cover 1 over the upper edge of the container 2 when the closure cover is fitted face down over the bead 3. As shown in FIG. 2, the periphery of the container bead 3 forms a seal against lid 1.
- a raised annular portion 16 is shown in FIGS. I3 and 7 as projecting above the top wall 6.
- Inverted channel 7 is connected to annular portion 16 by an arcuate bead 17 which extends around the channel forming a link between it and the annular portion.
- the raised annular portion 16 stiffens cover 1.
- the cover 1 is made of a relatively light plastic material. For this reason, any large cover needs stiffening against folding.
- the indentations or notches 20 shown internally of the raised annular portion are used to prevent lids from sticking together when they are stacked. The structure for stacking is discussed in greater detail in succeeding paragraphs. I
- the series of extended portions 8 snap under the cup bead when the snap-on cover is in place to form a detent means.
- the connecting lateral walls 21 and connecting back wall 22 between the arcuate shaped members 10 which walls form part of the exterior of the conical skirt are actually U-shaped walls to form the exterior ribs 33.
- the walls 21 are paired on each side of each arcuate shaped member 10 and their upper ends connect to the extended portions 8 while their uppermost end portions connect to the lower and outer wall 29 of the inverted channel (FIG. 7).
- the channel itself is a continuous rounded section.
- the back wall 22 has side walls 21 attached at each side along its length. The top of the back wall 22 connects to the outer wall 29 of the inverted channel. The bottom of the back wall connects to the angled lower rim 24.
- the lower part 30 of the arcuate shaped member 10 has an inside diameter which is greater than the maximum outside diameter of the channel 7. The difference of these diameters is somewhat greater than the wall thickness of the cover.
- the lands l engage the bead 3 all around the cover and as the lands move further downward, the arcuate shaped member and waist 9 may flex laterally to allow the elongated part of the lower arcuate member to slide over the exterior of the head.
- the head 3 then fits into the inverted peripheral channel 7 to form a snug nesting similar to that shown in FIG. 2.
- the channel and bead do not fit with perfect precision due to irregularities of material and forming.
- the cover assumes a configuration something like that shown in FIG. 3.
- the elongated arcuate member 10 and related parts act as a spring both when the lid is being snapped onto the container and when it is being removed from the top of the container. These parts deform somewhat with the retention lugs of the waist 9 being flattened a bit as the bead passes the waist.
- the principal springing action is imparted by the outward motion of the skirt 5 before the container bead 3 is snapped under the waist and into the channel.
- the paried lateral walls 21 are flexed also. Since these paired lateral walls 21 normally are curved and flat, their flexure simply imparts a greater curvature to each wall.
- the peripheral channel 7 and skirt 5 look somewhat similar to the showing in FIG. 3. Here the waist 9 is a bit distorted as the portions 8 pass over round bead 3 and waist 9 is forced back when it passes over the bead. Rim 24 helps to prevent splitting of the skirt when it is forced on over the bead 3.
- FIG. 4 A plan view of our snap-on closure or lid is shown in FIG. 4.
- a flat top wall 6 which extends laterally to include the raised annular portion 16.
- the raised annular portion 16 is formed into the top wall 6 and the outer wall 32 of the raised annular portion has a sloping surface as shown in FIGS. 2 and 3.
- An arcuate cross-sectional bead 17 is at the bottom of the slope and connects the outer wall of the raised annular portion 16 to the inverted peripheral channel 7.
- the inverted peripheral channel 7 connects the arcuate cross-sectional bead 17 to the peripheral cylindrical skirt 5 which is the outermost element.
- Ribs 33 are of about one eigthth inch in width and are equally spaced at aboutu 54 positions around the peripheral cylindrical skirt 5 where the cover has a diameter of about 3 5/8 inches.
- Stacking ledges or notches 20 are located in the raised annular portion 16 and the sides 34 of each notch slope at a small angle.
- the ribs 33 around the periphery of the lid have a flat U-shaped cross section (FIG. 5).
- the stacking notches 20 are spaced at unequal intervals around the annular portion 16 in a manner to most readily avoid dovetailing of the notches one in the other when the lids 1 are stacked one upon the other as shown in FIG. 7.
- the spacing of these notches is 75and 50, respectively.
- Each of the notches 20 occupies a space extending about half way through the radius of the raised annular portion 16.
- Each notch 20 is located in the inside wall of the annular portion and has a flat bottom wall 35. When the covers are stacked, the bottom 35 of the notch lies on the top wall 36 of the raised annular portion 16 (FIG. 7).
- the shape of walls 21, 22 of the ribs 33 are shown in .cross section in the view of FIG. 5. However, neither the vertical shape of the ribs nor of the elongated vertical curve which constitutes the arcuate shaped member (land) 10 is shown in FIG. 5. A vertical section across them is found in FIGS. 2, 3 and 7.
- the flat U-shaped rib 33 is relatively easy to form and itself presents a U- section as does the inner spring portion forming the waist 9.
- FIG. 7 A full vertical cross section of a cover taken along the line 77 of FIG. 4 (where FIG. 4 is a stacked pair of covers) is shown in FIG. 7.
- the waist 9 is made up of a series of tooth-like projections 8 extending into the interior of the cover.
- a notch 20 is shown in vertical cross section.
- the back wall 34 extends upward from the flat bottom wall to the upper wall 36 of the annular raised portion 16.
- the vertical distance from the top 36 of the annular section to the top of the bottom wall 35 of the notch is about equal to the vertical distance from the top of the channel 7 to the top of the shoulder 11.
- the notches may be rectangular in shape as shown by the notch 40 of FIG. 6.
- the location of these notches has the same spacing around annular ring 16 as in FIG. 4 and for the same reason.
- the bottom wall of the shoulder 11 falls onto the top wall of the inverted channel 7.
- the covers 1 are held apart mainly by the stacking notches or ledges 20 and are held from sliding in relation to each other by a close fit between the lower part 30 of the arcuate shaped member and the outer part 29 of the inverted peripheral channel 7.
- the inner part of the arcuate member has a dual function.
- the first function is that the land 10 engages the outer edge of the container bead 3 when the snap-on reclosure cover 1 is pressed over this edge.
- the diameter of the lower outer wall 30 is slightly larger than the diameter of the container bead to guide the container bead upward.
- the second function is that when the lids are stacked, the inner intermediate portion or shoulder 11 rests against the outer wall of the inverted channel 7.
- the lowest inner wall surface 30 of the arcuate member guides and engages the container bead as the cover is pressed onto the container.
- As the cover 1 is pressed onto the container bead most of the bead slides directly and easily by the waist and into the inverted channel 7 and remains there.
- the last portion of the wasist 9 to pass over the bead 3 encounters resistance from bead 3 and deforms somewhat to pass over the bead. Bead 3 also deforms inwardly. The amount that the bead 3 deforms depends largely on the softness or hardness of the material from which the container 2 vis made compared with the material of the cover 1.
- the last portion of the skirt 5 to snap on turns outward somewhat while it is passing over the bead.
- the skirt is turned ourwardly somewhat as shown in FIG. 3.
- the outer rim 24 of the skirt is placed in tension and elongates somewhat.
- the skirt does not split because the tension and elongation are to some extent distributed around the entire rim.
- a material which has appropriate forming and elongation characteristics is I-Ii- Impact Styrene.
- Straw slot 38 is located in the top wall 6 (FIGS. 4 and 6). This slot may be of any sort; for example, an arcuate weakening means or cross cuts to form a localized weakened area. This area may be pressed inward to allow a straw to be inserted.
- annular section 16 acts as a stiffener for the cover, a spacer for stacked covers and a retaining wall for liquid spilled out of the straw slot.
- Ring 16 is located interiorly of bead l7 and bead 17 provides a secondary wall against spilling of liquid from the straw slot.
- the cover When the cover is used as a coaster the cover is placed so that the coaster rests on rim 24. The cup is set in the cover and any liquid spillage falls within the annular ring 16.
- the configuration of the lid is almost the same as the configuration of the lid of FIG. 2.
- the rim 41 of FIG. 8 is analogous to the rim 24 of FIG. 2.
- rim 41 is about one and two tenths longer in vertical dimension than the rim 24 and the land 10 is shortened by very nearly the amount that the rim is lengthened.
- the distance from the high point of inverted peripheral channel 7 to the bottom of the rims 24 and 41 is identical in the embodiment of FIGS. 2 and 8.
- the spring action of the detent means is the use of irregularly spaced stacking ledges about an annular raised portion to avoid dovetailing on stacking.
- Another advantage is the shape of the inner surface of the skirt which in conjunction with the outer surface of the skirt and the outer surface of the channel gives lateral stability and vertical support to lids which are stacked one on another.
- the raised annular portion improves the rigidity and stacking quality of the lid.
- annular portion raised above the flat wall and having an inner wall connected to said generally circular edge of said central flat wall and an outer wall connected to said inner edge of said arcuate crosssectional bead.
- a snap-over cover for containers having an external peripheral bead around the upper edge thereof, said cover being formed of an easily flexed material as set forth in claim 2 in which each said arcuate land is formed on a circle of diameter at least equal to the outer diameter of said inverted peripheral channel.
- a snap-over cover for containers having an external peripheral bead around the upper edge thereof, said cover being formed of an easily flexed material as set forth in claim 5 in which said notches are molded into the inner wall of said raised annular portion and spaced from each other 75and 50respectively whereby the notches of one cover in nested relation with another cover have the least tendency to fall into each other.
- annular raised portion having an upper wall, an inner wall and an outer wall and extending adjacent said inverted peripheral channel
- a snap-over cover for containers having an external peripheral bead around the upper edge thereof, said cover being formed of an easily flexed material as set forth in claim 8 in which said notches form a rectangular recess into the inner wall of said raised annular portion.
- a snap-over cover for containers having an external peripheral bead around the upper edge thereof as set forth in claim 9 in which said notches form a recess in the inner wall of said raised annular portion having side walls with a curved cross-section and a flat bottom wall.
- top wall includes a flat wall in the center of said container having an outer generally circular edge, a plurality of extensions along the circular edge of said flat wall, and an annular portion raised above the flat wall whereby the extensions of one cover bear on the annular portion of another cover in nested relation therewith.
- a lid of flexible material for gripping and sealing engagement with a container having an external peripheral bead around the upper edge thereof comprising:
- a central panel having a generally circular margin defining its circumference
- a curved bearing surface having a shape congruent to a segment of the continuous rounded section of said inverted channel whereby said curved bearing surface rests on said continuous rounded section when one cover is stacked above another cover.
- said raised annular portion includes an inner wall connected to said generally circular margin of said central flat wall and an outer wall connected to said inner edge of said channel;
