March 1 ,1927. 1,619,136 w. H. KNOWLES BOTTLE CLOSURE Filed May 8, 1924 INVENTOR ATTORNEY Patented Mar. 1, 1927.
UNITED STATES WILLIAM H. KNOWLES, OF PORT CHESTER, YORK.
BOTTLE CLO-SURE.
Application filed May 8, 1924. Serial 110. 711,775.
This invention relates to receptacle closures, and is particularly adapted for use in connection with containers having the commonly accepted characteristics of milk and cream bottles An object of an improved device of the character described, by which a receptacle may be closed and sealed in such a manner as to 'be free from dust and erms. I
A further ob ect is that of providing a device of this type, which when once sealed may not be surreptitiously-opened and resealed without detection.
A still further object is that of constructing a closure capable of ready application to or removal from a receptacle.
Another object is that of providing an article of the type stated which will efliciently perform the purposes for WlllCh it is intended, and which will also be economically and readily manufactured and assembled.
The invention accordingly comprises an article of manufacture possessing the fea-- tures, properties, and. the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawing. in which:
Figure 1 is a plan view of one embodiment of the improved closure and showing the parts of the same in open position;
Fig. 2 is a side elevation of the device as shown in Fig. 1; 1
Fig. 3 is a plan view similar to Fig. 1 but illustrating the article with its parts in closed or sealed position.
Fig. 4 is a side elevation of the closure as shown in Fig. 3 and I Fig. 5 -is an enlarged sectional and fragmentary view and showing a certain detail of construction: 1
It will be noted that in the illustrated embodiment the invention has been depicted as being in the nature of a closure such as is particularly used in connection with milk.
bottles and similar receptacles. While the invention is primarily dedicated to this purtliis invention is to provide pose, it is to be here understood that the closure might, if desirable, be changed in construction, and if necessary, diiferentmaterials might also be employed in order to adapt the invention to other uses.
Thus, in the aforedescribed views, it will be seen that the reference numeral 1 indicates in the present instance a cap or shell of tearable and preferably fiexible material, as V i for example, paper, thin metal, etc., etc.
It will be understood that this cap. is of suflicient slze to accommodate within its body those portions of the receptacle 2 which a are adjacent the mouth thereof, and thus it Wlll be apparent that the cap ma be applied to and removed from t e receptacle.
Now, with a view of providing means which will serve to incorporate in the closure qualities by means of which a tight seal will be assured, it will be, observed that the u per readily face of the cap may be dished,.as has n indicated at 2?. As a consequence. an'.in-- wardly extending portion is provided within the interior of the cap body, and if the circumference of the side wall of'this dished portion is substantially equal to thecircumference of the receptacle mouth, it will be apparent that upon the cap being applied to the receptacle neck the inwardly extending portion of the cap will act as a stopper and thus prevent the fluid from escaping from the receptacle mouth.
It will be observed that the body of the cap also includes in the present-instance, downwardly extending side walls 4, and it will'be appreciated that after the closure has been applied to the receptacle and if a slight downward pull is imparted to these side walls that this action will necessarily result (due to the'fact that the entire cap is of somewhat flexible material), in a pull being transmitted to the side wall and base of the dished portion of the cap, which will tend to cause these parts to ride upwardly toward the outer end. or mouth of the receptacle. This tendency of the parts to act in the 'man ner specified will primarily be manifest, to
the greatest extent, by the side walls of the cup portion being drawn outwardl rather than upwardly, due to the fact, as as been indicated at 3, that the cap is necessarily corrugated or crimped at this point, and as a consequence this action .will result in an intimate engagement being eflected between the adjacent faces of the receptacle and cap.
' downwardly extending walls 4 of the cap, a
tight sealing will be effected, not alone between the inner faces of the cap proper and the outer face of the receptacle neck. but also the stopper portion of the cap will be expanded to cause the side walls of the latter to form a fluid tight seal by intimately bearing against the inner face of the receptacle neck adjacent the upper end of the latter.
With a view of providing means for effecting this seating of the parts, it will be observed that the downwardly extending walls 4 of the cap are continued in the present instance in the form of an outwardly extending flange 5, and attached to this flange is a constricting element which serves to circumferentially compress the cap. This elementv may be in the nature of a wire or resilient ring 6 which has one of its endspiercing the flange 5 as at 10 and extending beyond the same as at 7, its body being disposed substantially adjacent to the upper face of the flange while its opposite end terminates in a prong 11, which may be extended through the flange as at 8, in a manner hereinafter described.
The article is furnished to the user in the form shown in Figs. land 2, i. e., one end of the constricting element is permanently attached to the cap while the body of this element extends eccentrically relative there to. Assuming that it is desired to close the receptacle, the cap is applied to the mouth and neck thereof, subsequent to which the prong 11 of the constricting element is brought to a position adjacent the point 7, and .by means of the operators fingers. or by means of a suitable tool, this prong is forced through the flange 5, and properly bent rearwardly as has been indicated in Fig. 5 in order to lock the parts. As the free end of the constricting and locking member is drawn towards its fixed end, the inner edge thereof will bear against the outer face of the cap and thus cause the inner face of the side walls 4 to bear against the outer face of the bottle neck.
It will be understood upon the initial application of the cap to the mouth of the receptacle that the stopper portion of the former will extend into the mouth of the latter. It is here to be noted that the receptacle is preferably formed adjacent its mouth with a curved lip, and the ringwill lie adjacent the same. Thus, upon the constricting member being actuated, it will be obvious, due to the fact that the movements of the latter are limited by means of the flange 5, that the walls 4 will tend to move inwardly and downwardly incident to the force exerted upon them, and this latter action will result in the stopper portion 2 of the cap being expanded to intimately engage the inner face of the mouth of the receptacle so that a tight seal will be formed, as has been afore brought out.
In addition to all the foregoing, however, and irrespective of whether the stopper portion is utilized or not, the constricting member will serve to lock the cap upon the neck of the receptacle, and due to the fact that the length of this element is preferably insufiicient to completely encircle the walls 4, it will be obvious that upon the end 11 of the ring being forced through the flange 5, the constricting member. according to the present construction, will be disposed concentrically relative to the receptacle neck, and a space 9 will exist between the ends of. the ring, which space may be suitably indicated, as for example, by a mark 12.
The ends of the locking member are thus joined together by material which may readily be torn or ruptured by any suitable means such as the operators fingers, a fork prong, knife point, etc. etc., so that the space indicated at 9 might be termed the rupture point of the closure. In this connection it is of interest to note, in order that the capmay not-be prematurely loosened, that it is preferable that the space 9 as in Fig. 5, shall be as free as possible from wrinkles, crimps, etc.
Thus, if the user desires to open the clo-. sure, this may readily be accomplished simply by suitably rupturing the flange 5 through the space 9. This action will obviously result in the ends of the constricting member being freed to move away from each other, and since the material of the cap has now been torn, it will be obvious that the cap may not again be used for the reason that it will be apparent to an observer that the olosure has been previously opened.
In conclusion, it will be appreciated that the closure may incorporate the stopper feature without necessarily utilizing a retaining element of the nature shown, and from the foregoing it will be understood that the objects of this invention have been accom- 'plished, and since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
