Description
~L2~363~
This invention relates to a dispensing closure for containers and more particularly to a two piece dispensing closure. There are a wide variety of dispensing closures which are provided with a dispensing orifice in the cap and a hinge lid to close the orifice. A nu~ber ~f these closures are designed to have the cap more or less permanently attache~
to the container so that the container contents must be removed through the dispensing orifice, and a number are made with the cap, lid and hinge being molded as a unit to form a one piece closure. Examples of this type of closure are shown in Montgomery and McAlinden U.S. Patent No. ~,371,095 and in Luker U.S. Patent No. 4,378,073. ~here it is desired to reuse the container and closure, as for example in food or condiment use such as catsup, mustard, honey or the like, the cap should be easily removed from the container for refilling, and the lid and cap should be easily cleaned.
A two piece closure offers an advantage from the cleaning standpoint and will provide continuing reuse without breakage which can occur from a continuing use of a live hinge structure where the hinge depends upon continuous flexing with a tendency to ear and cracking. Most two piece structures are made with a horizontal pin or trunion formed on one part and an engaging opening on the other part. This leads to an exposed hinge structure which projects to one side of the closure destroying symmetry of ~he closure.
It is therefore an object of this invention to provide a two plece closure which can be easlly taken apart for cleaning and reassembled for ~urther use.
., ~, :iLZ~;~6~S
It is another object of this invention to provide a two piece closure which inherently has the advantage that the cap and lid may be made of different colors improving the esthetics of the product package.
It is a urther object of this invention to provide a hinge which is not breakable.
It is still another object of the instance inven-tion to provide a two piece closure in which the hinge is concealed in the closed position of the closure to provide a full profile-symmetrical appearance.
The objects of the invention are accomplished by providing a two piece closure in which the first piece is a cap which is attached to the container by threads molded into the inner surface of a skixt portion of the cap which cooperates with complementary threads on the neck o~ the containerO This provides for easy removal of the cap for refilling the container, which maintaining the cap firmly affixed to the closure during its normal dispensing use.
In some instances, the cap can be formed integrally with the container which can take the form of a jar, bottle or collapsible tube~ The cap has an orifice or nozzle which is formed integral with its top surface through which the contents oE a container can be removed. The second piece of the closure is a lid which acts to close the dispensing opening on the cap. A plug member is integxally formed on the lld and positioned to engage the~dispensi~g opening on the cap to provide a self-cleaning, sealing and locking engagement with the lid. A hinge is~formed by molding the cooperating parts thereof in the cap and lid members, and~the hinge is designed in a msnner to permit the closure to be taken apart for easy cleaning and to be easily reassembled while providing no projecting parts to 3~3~;
distract from the symmetry of the closure. The cap has a pair of upwardly extending posts adjacent to its perimeter and each post has a spherical projection which faces the spherical projection on the other post. The lid is provided with a pair of complementary slots opening at the kop, the bottom and the periphery of the lid which sloks are ~urther formed with spherically concave indentations facing each other. The slots are aligned to receive the pair of posts and projections thus forming a hinge which allows the lid to move between an open and closed position by the pivotable movement of the spherical projections in the spherically concave indentations. The positions of the slots and posts may be interchanged so that the posts are formed integral with the lid and the slots are formed within the cap to perform an identical function. While in the pre~erred embodiment, the projections on the posts face each other or in line with each other, or in fact the projections can be formed on both sides of the posts to mate with complementary concave indentations. Likewise, the projections can be formed in the slotwalls and the indentations in the posts, or one projection in each with a complementary indentation in the others. The hinge thus constructed provides pivotable movement of the spherical projections in the spherical concave indentations allowing the lid to move between an open and closed position with the overall fric-tion of the mating posts and slots retaining the lid in any intermediate position.
The presently preferred embodiment of the invention are illustrated in the accompanying drawing in which:
FIG. 1 is a perspective view of a two piece dispensing closure shown in its closed position and in association with a container, only the upper end of which is shown;
3~i35i Fig. 2 ls a perspective view of the two piece closure in its open position relative to a container, only a portion of which is shown;
Fig. 3 is a cross-sectional view taken on line 3-3 in Fig. l; and Fig. 4 is a cross-sectional view taken on line ~-4 of Fig. 3 showing the details of the hinge structure.
A two piece dispensing closure embodying the invention is shown generally at 10 having a cylindrical cap 12 which is adapted for use with containers 14. Cap 12 has a generally flat top 16 and a depending annular skirt 18A
The skirt 18 is provided with internal threads 20 which mate with complementary threads ~not shown) on the exterior of the neck of container 14. Cap 12 has a pouring orifice or nozzle 22 formed on top 16 through which the contents of the container 14 is normally dispensed.
The second piece of two piece dispensing closure 10 is lid 24 which is connected to cap 14 by hinge means 26.
Thus, the lid 24 may be swung from an open dispensing position to a closed position covering the pouring nozæle 22. Formed wikh lid 24 is closure plug 28 which engages with nozzle 22 when the lid is swung into its closed position in a manner to seal the nozzle 22 and to lock the lid 24 to cap l2 by the frictional engagement of plug 28 with nozzle 22. Also with the penetration of plug 28 into nozzle 22 each time lid 24 is closed, a self-cleaning ~eature is present. Lid 24 has a depending annular kirt which merges with the perimeter of cap 12 when the lid is in its closed position. The cap 12 is provided with an indentation 32 at its edge, opposite to hinge 26. Indentation 32 is beveled toward the top of the cap and is most suitably located on a diametric line with the pouring orifice 22 and the hinge 26.
~43635 This indentation 32 allows the user to grip the lid 24 to swing it into its open positlon.
Referring to Figs. 2 and 4, hinge means 25 is constructed by forming complementary engaging means adjacent the periphery on the cap 12 and the lid 24. Spaced apart rectangular posts 34 are ~ormed inteyral with cap 12 extend-ing vertically upward from, that is perpendicular to, ~lat top 16. One edge of each post 34 i5 in line with the outer periphery of the cap skirt 18. A spherically convex or curvilinear projection 36 is formed on each of the wider sides of the post facing each other. The lid 24 is provided with a pair of complementary, spaced apart slots 38 to receive posts 34, and each slot 38 is provided with a complementary spherical or curvilinear indentation 40 facing towards each other to receive the spherical projections 36 on each post. The slots 38 are formed with an opening in the top and bottom of the lid as well as the periphery.
Both the cap 12 and the lid 24 are separately molded from plastic material. The cap 12 and lid 24 are assembled together ~y pushing the posts 34 into slots 38 and forcing the complementary spherical projections 36 into the concave spherical indentations 40 to complete the hinge means 26 which allows the lid to mo~e between an open and closed position by pivotable movement of the spherical projections 36 in the spherical concave indentation ~0. When the lid 2 is fully closed so that plug 28 fully engages pouring nozzle 22, the cylindrical walls of the lid 24 and cap 12 are in alignment with each other and the hinge means are within the periphery of the cap and lid and the outer edges of the posts 34 are flush with the periphery of lid skirt 30 and the top of the lid.
*;2~3~i35 While the spherical projections 36 and the inden-tations 40 are shown in the preferred form of Fig. 4 to be facing toward each other, they could be operatively located on posts 3~ and in slots 38 facing outwardly away from each other~ The projections and indentations could al~o be located on the same side of the posts and slots, facing right or left as viewed in Fig. 4. The projecticns and corresponding i~dentations could also be located on both sides of the posts and slots, although this is not as desirable as a single projection on one side because of a greater stability, and frictional engagement offered by the flat surface on one side of the posts which better holds the lid in a predetermined opened position. It should be noted that the slots and posts can be interchanged so that the posts are formed on the lid and slots are formed in the cap.
While projections 36 and indentations 40 have been characterized as spherical, it should be understood that the term spherical and curvilinear embrace conical, frus~o-conical, substantially cylindrical and other curved or rounded surfaces as long as the projection and indentation are complementary to each other, and the rounded or cylindrical complementary surfaces are arranyed to permit free swinging about an axis of rotation through both posts.
Also, the top of cap 12 is formed with a cylindrical surface 27, as shown in Fig. 3, which is concentric to this axis of the hinge. If it is desired to maintain or have the lid seek a particular position as it is opened, the rounded or spherical surface can be ovaled.
Also, as seen in Fig. 4, the~axis of the hinge passing through both projections is above the mid-point of the post to prevent interference.
~Z~363~
The two post design offers a hinge of great stability so that the lid does not become disenga~ed from the cap during normal opening and closing use, but the two parts can be taken apart for thorough cleaning, for e~ample, when the container is refilled. With this unique two post design, there is no protrusion o~ the hinge nor is there any cavity necessary to accommodate the hinge structure. In fact the hinge is hidden in the closed position presenting an esthetically pleasing symmetrical appearance with much less vulnerability to the hinge during normal handling.
The two piece closure offers a virtually indestructable structure in normal use as compared to a one piece cap-lid-hinge structure which has a live hinge.which is often creased to facilitate holding in an open position, thereby presenting an area sub~ect to cracking and failure after extended use.
The two piece structure offers other advantage over the single piece structures such as the fact that the cap and lid may be made with different colors improving the esthetics of the product package. With a two piece closure it is possible to improve the tooling for higher production rate. For example, the cap might be made in a 32 cavity mold whereas the lid might be made in a 64 cavity mold, making it possible to run both molds at optimum capacity instead of limiting the capacity of a one piece structure mold to the slowest or most difficult portion of the closure design being formed.
This invention relates to a dispensing closure for containers and more particularly to a two piece dispensing closure. There are a wide variety of dispensing closures which are provided with a dispensing orifice in the cap and a hinge lid to close the orifice.
