Description

March 28, 1961 F. s. BARTLETT 2,977,015
CAP CLOSURE FOR BOTTLES AND TUBES Filed July 21, 1958 INVENTOR. FLORA S. BARTLETT BY wwgw A T TORNE VS z,971,015' i I CAP CLOSUREFOR BOTTLES AND Flora Bartlett, The Faii-montHotel, San Francisco, Calif.
Filed July z1,,19ss;-s r. No. 749, 75v 2 Claims. .(Cl. 215-46 f lation. thereto, and which cap isformediwithfa discharge opening which is positioned to register with a similar discharge opening in said head upon rotation of the cap to a .predetermined degree.
Another object of the invention is the provision of a blank of sheet metal formed for drawing intoa closure cap on a bottle or collapsible tube in permanently affixed position on' the latter but rotatable relative thereto.
A still further object of the invention 'is the provision of a blank sheet metal" having a relatively soft, resilient,
coating of plastic covering a side thereof and which blank .is adapted to be, drawn over the discharge head and opening' of a container that may be of hard or relatively soft material such as metal, glass or plastic and permanently secured to such head, with said covering a slidable sealing engagement with the said head.
An additional object is the combination of a bottle or dispensing tube having a discharge head thereon formed with a discharge openingtherein, and a dispensing closure of metal permanently but rotatablysecured on said head, which closure is formed with an opening therein adapted to be closed byan imperforate portion of said head when said closure is in one position during its rotation, and to register with the opening insaid head when said cap is rotated a predetermined degree fromsaid registering position. i
Heretofore most caps for bottles or tubes are threadedly secured thereto, or are slipped" onto and off the head for lo ngra. schar e. penlngin he hea i q p ing it to enable discharge. In these instances the cap or closure is frequently dropped or lost and attempts to secure the cap onto the head have resulted in relatively complicated and expensive structures, and little if any attempt has been made to seal the head against possible leakage.
The present invention is economical and easy to install, and is press sealed onto the head for permitting easy rotation relative to the latter and at the same time effect a fluid seal. 3
Other objects and advantages will appear in the description and in the drawings.
In the drawings, Fig. l is an exploded isometric view of a bottle and a closure therefor.
Fig, 2 is a plan view of the blank from which the closure of Figs. 1, 3 may be formed.
Fig. 3 is an enlarged vertical sectional view taken through the bottle of Fig. 1 when the closure is on the bottle. I
Fig. 4 is a reduced size top plan view of Fig. 3.
Fig. 5 is an isometric, fragmentary view of a modified form of the invention disclosed in Fig. l.
2,977,015 Patented Mar. 28, 1961 Fig, 6' is a fragmentary,-- side elevationalview-y partly 7 isa P view 'of-the blank from which the clos l ofFigi S'fQrmed;
In detail, the blank from which acap such as is seen in Fig. 1 is formed comprisesa circular disc 1- of relatively thin sheet metal'having a marginal'portion 2, a segmentof which is removed-to form arecess-4 that may extendthrough an arc of any desireddistance, but preferably somewhere between approximately 30 to degrees.
This disc 1 preferably'has arelartivelyyieldable coating 5 ofplastic, such asapolyethylene, onone side there'- of, andthe" discis adapted to be drawn ina suitable diei to form the side walls 60f a cap 7 (Figs. 1, 3') that is adapted to closely fit over and enclose the head 8 of a container 9so that the plastic coating 5 is against-the surface of-the head 8'. The central portion 10 of the disc is adapted to: form the top of cap7, and the portion intermediate the central portion 10 and marginal portion 2, is adapted to formsides 6 while marginal por tion '2 is adapted'to be crimped below a shoulder 11 on said head, with aradially outwardly projecting lug 12 integral with said head, :and depending from shoulder 11, 'extending into recess 4. I g
' When cap 7 is formed'from'disc 1, and is positioned over head 8, it is in relatively close frictional engagement with" head 8. The crimping of the marginal"por "tion- 2 under shoulder 11 draws the central portion. 10
snugly against the outer end surface of the head 8, Has tic coating 5, being slightly resilient,- will be under slight pressureto form a fluid tight seal between the axially facing end surface of the head and theportion 10 of the cap, and the'fa'ct that this liner or coating extends over the inner sides of the cap and is disposed between the flange formed by marginalportion 2 when the latter is crimped to extend below shoulder 11, provides a pair of relatively soft resilient bearing surfaces yieldably holding the cap tight against the head Sat all times.
The portion 10 is formed with an eccentrically positioned discharge opening 13 that is adapted to register with the upper open end of an open endedpassageway 14 in-head 8, the liner endof which passageway communicates with the interior of the container 9., This registration is only when cap '1 is rotated in one direction until the one side 15 of recess 4 engages a side of lug 12,. 'Rotation of the cap 7 in the opposite direction until th'eoppo'site side 17 of recess 4 engages-slug 12 will recylindrical outer portion against which the cap 7 is seated,
and the other part is a central plug 18 having a recess extending axially thereof from end to end and opening radially outwardly, so that the open side is closed by the cylindrical inner surface of said outer portion of the head. This structure enables the formation of the passageway 14, which is the aforesaid recess in its cooperative relation with the said outer portion of head 8. In other words, the container 9 may be formed in the usual manner and by conventional dies, and the plug 18 is merely secured in the mouth or throat of the container with the recess or passageway '14 in a position to register with opening 13 as above described. The axially outer surface of plug 18 is preferably coplanar with the axially outer surface of the head 8.-
Fig. 5 shows a structure similar to that of Figs. 1-3 except that the disc from which the cap is formed has an opening 20 that is in the position 21 that is between a central portion that; corresponds with end of Fig. 1
(except for opening 13) and marginal portion 22.
In this form of invention, it is immaterial whether the outer end of the throat in thehead of the bottle is open or'closed, sincethe opening is adapted to register, at one end of the rotary movement of the cap, with an opening 23- in the side of the head. Y j
Lu-g 24 is similar to lug 12 and recess 25 in the'marginal portion 22 isthe same as recess 4 in cap 7. h
. .With the inventionas disclosed in Fig. '5, the cap may be lined with plastic the same as in the case of cap 7, and it functions in the same manner. Discharge of the limited to the precise details of construction set forth, but
" desire to avail myself of all changes within the scope contents ofthe container is from the side of the head instead of from the end.
Figs. 6, 7 show a modification of the structure disclosed in Fig. 5. 'The blank 26 may be exactly the same as the one that forms the cap shown in Fig. 5, except that there is no marginal recess in the marginal portion 27.
The discharge opening 28 is formed in the portion that becomes the side wall of the container, and the head? of the container has a plurality of equally spaced radially directed openings 30 therein, with the space between adjacent openings 30being substantially greater than that of I opening 28. I
Inasmuch as the inner plastic coating 32 forms a snug friction fit between the head and the cap, the latter .will
stay in the position to which it is rotated, and the user can readily see when the opening 28 is in register with 2;,
it may be of metal, or glass, or of any other suitable material.
It is pertinent to note that in each of the examples the cap is of a ductile metal and while in some instances the plastic inner coating may not be essential, it enables the employment of cap structure generally of the character disclosed where heretofore it has not been possible from a practical standpoint.
This plastic liner, being substantially impervious to corrosion and to reaction with the chemicals normally employed in cosmetics, skin creams, and the like, will not contaminatethe contents of the container, not cause a deterioration in the sealing effect thereof.
While I have illustrated preferred embodiments of my invention, modifications may be made without departing from the spirit of the invention, and I do not wish to be of the appended claims.
I claim: 1
