Abstract
A grip cap for a container has a thermoplastic shell in an inverted cup shape with a top wall and a skirt bounded by a lower rim. An elastomeric layer is integrally molded to the cap shell along the outer surface of the top wall and the skirt as well as along the underside of the lower rim. This layer defines multiple spaced apart and raised vertical ribs joined by a pad at the top wall and a gasket extending along the lower rim. The ribs and the pad provide a cushion and the gasket can seal against a shoulder of the container when tightened. Also disclosed is a two-shot method of molding such a grip cap, including integral resilient material at the outer surfaces and the underside of the cap shell rim.
Description
- This application claims benefit to U.S. Provisional Application Serial No. 60/396,658 filed Jul. 17, 2002.
- Not applicable.
- 1. Technical Field
- The present invention relates to container closure caps and the like and, in particular, to lightweight plastic caps having improved gripping and sealing surfaces.
- 2. Description of the Related Art
- It is well known to close openings in containers by snapping or threading caps onto the mouths of the containers. Vertical ridges are commonly formed in thread on caps to increase the grippable surface area of the caps and make it easier to screw the caps onto the containers. The grip is further improved by having soft, tactile material along the outer surfaces of the caps. U.S. Pat. Nos. 5,865,353 and 6,257,431 describe containers having caps with elastomeric gripping zones arranged on mating parts of hinged caps that facilitate opening the caps.
- Sealing is another issue for closure caps, particularly for liquids and perishable ingestible goods. U.S. Pat. No. 4,143,785 discloses a cap with special inner flanges that seal against the inner and outer diameters of the container to which the cap is threaded. U.S. Pat. Nos. 4,308,965 and 4,461,393 describe improved sealing arrangements in which the caps are formed of two dissimilar plastic materials using a two-shot molding process in which a more rigid material forms the main bodies of the caps and softer, relatively resilient seals are formed on the inside of the caps. The two-shot molding process fuses the dissimilar materials together as a unitary component, without additional bonding techniques being required.
- The present invention is a grip cap having a generally inelastic shell and a resilient grip layer formed in a two-shot molding process to be a unitary part with improved gripping and sealing attributes.
- In particular, the present invention provides a grip cap having a cap shell, defining a top wall and a skirt depending down from the top wall to a lower rim for receiving a neck of the container. A plurality of raised ribs, resilient relative to the cap shell, are integrally molded to an outer surface of the cap shell in spaced relation and extending along the skirt between the top wall and the lower rim.
- In another aspect of the invention, the lower rim of the cap shell has an underside that faces generally away from the top wall. A relatively resilient grip layer is integrally molded to the cap shell so that a plurality of raised ribs extend along the outer surface of the skirt and so that a gasket extends along the underside of the lower rim.
- In various preferred forms, the ribs are spaced equi-angularly about an axis about which the cap shell is concentric and are joined at an elastomeric top pad of a diameter less than the top wall of the cap shell and at a ring-shaped gasket extending under the lower rim to abut a shoulder of the container when the cap is in position closing the container. The shell is molded to extend upward through the top pad to present raised indicia. The ribs and the shell can be the same or contrasting colors. The cap shell can have one or more flanges extending down from the top wall that engage and retain an inner cap removably mounted over the mouth of the container.
- In yet another aspect the invention provides a two-shot method of making a grip cap for a container. The method includes injecting a thermoplastic resin between first and second die parts to form a cap shell conforming to the interior of the die so as to have a top wall and a skirt bounded by a lower rim at an angle to an outer surface of the skirt, then, supporting the cap shell on the first die part and interchanging the second die part with a third die part. The cap shell is allowed to shrink on the first die part as it cools so that the lower rim is spaced from an adjacent surface of the first die part. The first and third die parts are then brought together with the cap shell therebetween and an elastomeric resin is injected between the cap shell and the first and third die parts to mold a grip layer integrally with the cap shell having a plurality of raised ribs extending along the outer surface of the skirt and a gasket extending along the lower rim.
- Thus, grip cap of the present invention has an improved gripping surface for a user's fingers when loosening the cap from or tightening the cap onto a container. The ribs and top pad provide cushioning for the underlying shell against possible impact while using minimal amounts of the elastomeric material. The gasket may provide for resilient sealing against the container and frictional contact holding the cap closed against rotation when it is sealed. The grip cap can be adapted to be connected to conventional threaded and other suitable under closures for closing an opening in the container.
- These and still other advantages of the invention will be apparent from the detailed description and drawings. What follows is a preferred embodiment of the present invention. To assess the full scope of the invention the claims should be looked to as the preferred embodiment is not intended as the only embodiment within the scope of the invention.
- FIG. 1 is an exploded perspective view of the grip cap of the present invention with a corresponding container;
- FIG. 2 is a partial cross section of the grip cap of FIG. 1 taken along line2-2;
- FIG. 3 is a partial sectional view of a two part die shown in position to mold a generally rigid shell of the grip cap;
- FIG. 4 is a view similar to FIG. 3 showing the cap shell supported on one part of the die with the other part removed and showing that the cap shell has shrunk somewhat on the die so that a lower rim of the cap shell is spaced therefrom; and
- FIG. 5 is another similar view showing the die with the cap shell on the associated disc part and a new mating die part in position to mold an elastomeric grip layer onto the cap shell.
- Referring to FIGS. 1 and 2, a
grip cap 10, suitable as a screw lid or other type of closure for acontainer 15, may include a cup-shaped,cylindrical cap shell 12 generally symmetrical about a centralvertical axis 18. Theshell 12 has atop wall 14 from which askirt 27 depends downward, which is bounded by alower rim 28, all of which defines anopen underside 16 that may receive aneck 17 of thecontainer 15 as will be described. - The
cap shell 12 may be preferentially molded of a relatively inelastic thermoplastic resin such as polypropylene and may, for example, have a smooth, brightly colored outer surface attractive to the consumer. - Attached to the outer surface of the
shell skirt 27 are a series of axially extendingribs 20 angularly spaced about theaxis 18 and running from thelower rim 28 to thetop wall 14 where they may join at atop pad 22 of a diameter less than thetop wall 14 of thecap shell 12. At thelower rim 28 of thecap shell 12, theribs 20 join a ring-shaped gasket 26. Thegasket 26 extends under therim 28 to abut ashoulder 19 of thecontainer 15 when thegrip cap 10 is in position closing thecontainer 15. - The
ribs 20, thegasket 26, and thetop disk 22 are part of an over molded grip layer formed in the second operation of a two-shot molding process (described below) of an elastomeric resin material such as thermoplastic vulcanate (TPV) or thermoplastic elastomer (TPE) and may be of the same or a contrasting color as theshell 12. During this two-shot molding process, theribs 20, thegasket 26, and thetop disk 22 are fused to the material of theshell 12 without the need for adhesive or the like. - The
ribs 20 provide an improved gripping surface for a user's fingers when thegrip cap 10 must be turned aboutaxis 18, and along with thetop pad 22 provide cushioning for theunderlying cap shell 12 against possible impact while using minimal amounts of the elastomeric material. Thegasket 26 may provide for a resilient sealing against thecontainer 15 and a frictional contact holding thegrip cap 10 closed against rotation when it is sealed. Thegasket 26 also accommodates shrinkage of the material of thecap shell 12 before the over molding without the need for other compensation mechanisms. - Portions of the material of the
cap shell 12 may be molded to extend upward through thetop pad 22 to presentletters 30 or decorative embossments. Extending downward from the upper inner surface of thecap shell 12 may be one ormore flanges 32 to directly engage thecontainer 15 or, as shown, to hold a conventional threadedinner cap 34 havingthreads 36 to engagecorresponding threads 37 on thecontainer 15 and agasket material 38 providing sealing on theneck 17 of thecontainer 15 when thecap 10 is in position. Although not shown, theflanges 32 preferably have inwardly extending lips (generally parallel to the top wall 14) and can also have vertical ribbing that mates with corresponding vertical ribs on theinner cap 34 such that their engagement prevent relative rotation. - Referring to FIGS.3-5, as mentioned, preferably the
grip cap 10 is formed using a two-shot molding process. Specifically, a thermoplastic resin is injected between twohalves 50 and 51 of a die 54 (though passage 53) of the die to form the cap shell. After sufficient cooling period, the two die parts are split by withdrawing part 51 away frompart 50 and retaining thecap shell 12 ondie part 50, as shown in FIG. 4. The removed die part 51 is then interchanged with another diepart 52 having an interior surface configured to form the resilient grip layer, including thetop pad 22, theribs 20 and thegasket 26. As thecap shell 12 cools it shrinks on the supportingdie part 50 so that thelower rim 28 is spaced from an adjacent surface of thedie part 50. The gap illustrated in FIG. 4 is thus formed as thecap shell 12 is supported bydie part 50 at thetop wall 14. Thenew die part 50 is then joined to theoriginal die part 50 with thecap shell 12 therebetween and an elastomeric resin is injected (through passage 55) around thecap shell 12 betweendie parts 50 to mold the grip layer integrally with thecap shell 12. This technique thus allows the grip layer to be molded onto an underside (at the lower rim 28) and the outer surfaces of thecap shell 12 simultaneously in a single operation. - The grip cap of the present invention thus has an improved gripping surface for a user's fingers when loosening the cap from or tightening the cap onto a container. The ribs and top pad provide cushioning for the underlying shell against possible impact while using minimal amounts of the elastomeric material. The gasket may provide for resilient sealing against the container and frictional contact holding the cap closed against rotation when it is sealed. The grip cap can be adapted to be connected to conventional threaded and other suitable under closures for closing an opening in the container.
- It should be appreciated that merely a preferred embodiment of the invention has been described above. However, many modifications and variations to the preferred embodiment will be apparent to those skilled in the art, which will be within the spirit and scope of the invention. For example, the cap may be used in non-threaded applications, for example, as press fit to the top of the container or in snap-type closures as are well known in the art. Therefore, the invention should not be limited to the described embodiment. To ascertain the full scope of the invention, the following claims should be referenced.
