Appiigafibniiiermiy zajis'zl seriai No. 44,868.
My invention relates to complete' closures' for containers, such' as bottles or jars, `in 'fot the closure'd container 'with yits inwardly which a closure proper is applied to the' container to hermetically 'seall it and, protect the contents against deterioration'until the contents are to be used when it is removed. iissociated therewith I use a slip or dust cap,
, preferably made lof seamless, drawn metal which is secured to the closure .proper until the latter is to beV removed. and which 1s thereafter used to close the container to maintain the contents in a clean and sanitary con-` dition until they are used up. it is my object to produce a simple, cheap and sanitary closure and cap, the closure member of which can be applied to containers by existing machinery and which does not necessarily require a specially finished bottle or jar in order that it may be used.
in the drawing I have shown embodiments oi' complete closure applied to a bottle. Fig. l is a side view, partly in section, oi" oneform of my improved structure; Fig. 2 a like view of the structure of Fig. l with the closure proper removed and the slip cap in place; Fig. 3 a bottom view of the slip cap; Fig. 4r a detail, sectional View of the slip cap and closure proper ot Figs. l, 2 and 3 interlocked On a bottle; Fig. 5 a like view of the slip cap in position for removal from the permanent closure; Fig. 6 a sectional view of a modilied closure proper and the slip cap associated therewith; and Fig. 7 a side View of the slip cap shownin Fig. 6.
In the form shown in Figs. l, 2, 3, 4 and 5 the bottle or other container l has the regular crown finished lip 2. rhe closure proper is the regular cap composed of a metal shell 3, with a depending skirt provided with a plurality oi corrugations 4 and a sealing gasket 5 and is affixed to the lip of the bottle in the usual manner. The slip cap is preferably made of drawn,
iii-use A,the slip cap is vpushed over-the top upper lends will engage the bottom edgev of the closure proper when the slip capis rin place thereon.
l To open the container the slip cap is twist,-
ed slightly-and pulled 01T, exposing the clo-` sure proper'. rlhis is then removed in the usual manner after which the slipv cap can be slipped on or off the container, protecting the contents from contamination. AThe slip cap, being preferably seamless, can loe-easily cleaned and kept in sanitary condition.
ln the inodied Jform shown in Figs. 6 and 7 I have shown how a slip cap may be lrictionally secured to a closure proper. The closure proper l0, may have a smooth skirt llinstead of the corrugated one of a crown cap, is spun over the lip of the bottle and the slip cap l2 has a series ot inwardly extending projections 13 so located and proportioned that they will frictionally engage the skirt of the closure proper and lsecure the slip cap to the closure pro-per. The slip cap is pulled OilI and the closure proper removed after which the slip cap is used in the usual manner. Y l am aware that specially finishedv bottles have been made to which bottles both the permanent, or closure proper, and the slip cap have been secured but my invention contemplates the hermetic sealing of the container at the packing'house with a closure pro-per and a slip cap which engages the closure proper instead of the container itself so that it cannot come off in transit or on the dealers shelf. The user can remove the slip cap without the use of tools and after the closure proper is removed the slip cap can be used in the usual manner.
I claim l. As a new article of manufacture, a slip cap `tor containers having in combination a top and depending walls, side Walls being provided with a plurality of inwardly extending projections in position to have their upper ends co-act with a container closure on a container, whereby the slip cap is secured to the closure and held against accidental displacement.
2. As a new article of manufacture, a container closure comprising a` closure proper provided with a top and a skirt, the skirt of which is adapted to engage a lip on a container, and a slip cap coniposedof a top and side walls, the side walls being provided with inwardly extending projections so located and proportioned that they will pass over the skirt of the closure proper and encomposed of a top and sidewalls, the sidel walls having inwardly extending .projec-V tions therein and adapted to t over the crown cap with the upper ends of the projections on the slip cap engaging the lower ends ot the corrugations on the crown skirt to prevent accidental separation of the two.
In testimony-whereof I have affixed my signature. Y Y
