CLOSING-CAP.
Specification of Letters Patent.
Patented April 2, 1907.
Applioationfiled August 16,1904. Serial No. 220,976.
cap.
To this end my invention consists in the features of construction and combination hereinafter particularly described and claimed.
. In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of a can fitted with my cap, and Fig. 2 is a section on line as m of Fig. 1.
In the drawings, A represents a can such as a syrup-can. Secured in the outlet-opening of the can is an ordinary threaded neck 2, having its upper end inturned to form a flange 3. Threaded to. screw over the neck 2 is a cap 4. The cap 4 is formed with a central opening 5, within which is fitted a frictiontop 6. Inside the top of'the ca is arranged a disk 7, of cork or other suita lematerial.
In order to hold the cork tightly clamped within the cap and also to hold the frictiontop out of contact with the cork and in position where it cannot be accidentally dislaced, I construct the top" of the cap as folows: The top of the cap is bent to form an outer rim 8, a concentric inner rim 10 surrounding the friction-top opening 5 and intermediate of said rims a rib 9 extending downwardly" toward the flange 3 of the neck. The inner rim 10 is lower than the outer rim 8, so that the friction-top will be protected by the outer rim against accidental displacement. The friction-to is of such height that its lower face will stan higher than the rib 9, and consequently outof contact with the cork. The screwing down of the cap will thus cause the cork to be squeezed between the flange 3- and rib 9 of the cap to form an air-tight closure.
In use where the cap is held too tightly to be easily unscrewed it is only necessary to lift the friction-top by insertingrany suitable instrument under its edge 1 1. he cork may then be punched or cut out below the opening 5to allow the contents of the vessel to be poured out. .When notin use, the frictiontop ma be pressed back into its opening. The or inary closed-top screw-cap is generally so firmly screwed into closing position in order to form an air-ti ht seal that it cannot easily be removed without a special instrument. "The user often cuts an opening in the can in order to gain access to 1ts contents, and the can thereafter must remain unsealed, thus subjecting the contents to fermentation. With -my invention this is avoided, as the friction-top is easily removed and placed back in closing position.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A closure of the class. described comprising in combination a neck, a cap fitted to said neck and provided with an opening in its top, said cap being formed with a contact opposed to the top of the neck, a secondary closure fitted to said opening, and a fiat unbent resilient imperforate disk arranged between the cap and neck, said disk being held in position by the pressure of the neck and the opposed contact-wall of the cap against the free edge of said disk.. I
2. A closure of the class described comprising in combination a neck, a cap fitted thereto provided with 'an opening in its top, a secondary closure for said opening, and a downwardly-extending rib carried. by the top of said ca in position to form a contact opposed to t e top of the neck.
3. A closure of the class described, comprising in combination a neck formed with an inwardly-flanged outer end, a cap fitted to said neck and provided with an opening in its top, a friction-cap fitted in said opening, a rim carried by said cap and extendlng above the top of said friction-top, and a circumferential rib carried by the top of said cap and extending below the bottom of said frictiontop.
4. A closure of the class described, consisting of a threaded neck having an inwardly-flanged outer end, a threaded cap fitted to "said neck, said cap being formed in its top with a central opening, and the top of said cap being bent to forman outer rim and then bent to form a downwardly-extending rib standing above said neck-flange, and then bent to form an inner rim standin than said outer rim, a friction-top tted to said inner rim, anda resilient disk arranged between said rib and neck-flange.
5. A closure of the class described, comlower rising a threaded neck havm anged outer end, a threade said neck and provided with acentral opening in its top, the top of said cap being bent an inwardlyto form an outer rim, an inner concentric rim around said openlng, and a downwardly-extending rib intermediate of said rims, a friction-top 'fitted in said opening with its upper edge lower than said outer rim, and its lower edge higher than said rib, and a resilient disk arrsliinged within said cap above said flanged nec 6. A closure of the class described comprising in combination a neck, a cap fitted thereto provided with an opening in its top, a secondary closure for said 0 ening, 'a rib extending downwardly from t e top of the cap toward the to of the neck whereby said rib and the top of the neck form opposed cl amping contacts, and an imperforate resilient disk inter osed between said rib and neck.
7. A c osure of the class described coml prising in' combination a neck formed with an top fitted to f inwardly-flangedouter end, a cap fitted to said neck and provided with an opening in its top, a secondary closure for said opening, and a resilient disk interposed between said to and the flanged end of said neck.
8. A closure of the class described C0111- prising in combination a neck formed with an inwardly-flanged outer end, a cap fitted to said neck and provided with an o )ening in its top, a secondary closure for said opening, a circumferential rib carried by the top of said cap and extending toward the flanged end of said neck, and a resilient disk arranged between said cap and neck.
In testimony whereof I affix my signature in presence of two witnesses.
