Application filed April 1, 1926. serial NOJ 99,149.

This inventionrelates to bottle closures and more particuldrly to cover-all caps for of cover-all cap for bottles.

More partlcularly 1t 1s an object of this invention to provide a cover-all --cap having means for causing the sameto'adhere to the neck of a bottle.

Another object of the present invention consists in the provision of a cover-all cap which can be adhesively secured to a bottle neck and provided with a tab adapted to be grasped to tear the cap loose from the bottle neck when it is desired toremove the same.

Bottles, such as those used in the delivery of milk, usually receive a disk-like cap within a counterbore near the top of the neck, which cap is adapted to retain the contents within the bottle under -normal conditions. However, in the handling of such bottles and in their delivery they are subject to contamina tion and on windy days considerable deposits of germ-laden dust may accumulate, not only on the cap, but around the edges of the neck of the bottle so that when the fluid is poured out after removing the cap it comes into contact with this contaminated surface. To prevent this the present invention contemplates the provision of a neck enclosing cap formed of paper or like material which may be placed over the bottle top and around the neck, covering the usual disk cap and all the portions of the neck which it is desired to retain in a sterilized condition. Various means have been suggested for securing such caps, which are generally termed cover-all caps, in position ,on the'bottle neck but most of them in volve theme of additional securing means such as resilient bands, paper strips, crimped wire or the like. The resent invention avoids the use of any a ditional securing ;,means. I y t .11: '2 For an understanding of the invention reference should be had to the accompanying drawing and following specification wherein is disclosed a single exemplary embodiment of the invention with the understanding, however, that various and sundry changes maybe made therein without departing from the spirit of the invention or the scope of the appended claims.

In said drawing:

Figure 1 is a side elevation, partly in vertical section, of the neck portion of a bottle having a cap constructed according to the present invention applied thereto; and

F'i ure 2 is a plan view of the blank from whic the cap is formed.

As illustrated 10 indicates the neck portion ofan ordinary bottle such as used by dairies for containing and delivering milk and like fluids. Above the narrowest contracted portion 11 of the neck there is an exterior bead 12 reinforcing the top of'the bottle. The inner portion of the neck near the top is provided with a counterbore- 13 adapted to receive the usual disk cap'14 which serves to retain the fluid within the container. lhe cap of the present invention is adapted to fit over the top of the bottle and cap 14,- around the head 12 and down alongside the neck 11.

The cap may be formed of any suitable material such as paper, light cardboard or other pulp, which may be treated with waterproof material if desired. However, this is not considered to be necessary unless the cap is to be used without the disk 14. InYFigure 2 at 15 is shown the blank from which the cap is formed. It is substantially square in plan with the corners clipped as at 16. The cap may be creased or precrimped before applying the same to the bottleneck, particularly if It is desired that the crimps orv folds be in the form ofregular pleats all facing in the same direction. However, it is not necessary gentialto the edges of the cap blank and -ap-- plied to but one side thereof. This adhesive ring is caused to adhere to the neck of the bottle just below the bead 21.2 by any suitable manner that if the adhesive should come necks.

loose from the bottle the cap would neverthew lessbe necked in below the bead and could not be removed without mutilating .it.

It has been suggested heretofore to use v paraffin for the purpose of causing a cap to adhere to abo-ttle neck but this has a number of disadvantages. In the first place, it will not adhere to a bottle neck which is wet, as often happens when milk is slopped over the edges during the filling process; second, paraffin is not a good adhesive and the cap must be tightly held in position until the paraffin hardens by cooling, thus resulting in -a slow operation; and thirdly, the parafiin isdiflicult to remove from the bottleneck during the washing process; It has been found that a gum is the most satisfactory article for securing the caps to the bottle Such a gum must be water-soluble and quick drying. It is referred, therefore, to use a water-solub e, quick drying, gum-like adhesive. It is water-soluble, and readily so, in order that the bottle necks may be readily cleaned after the caps have been removed. It must be quick drying so that the caps can be released almost instantly by the crimpers after the cap has been crimped about the bottle neck. This point is particularly important in order to hurry the cap applying operation. The adhesive must have the property also of adhering firmly to the bottle and yet permitting the cap to be' torn loose with facility.

The cap blank is substantially square in form in order to provide the tabs 18 formed by the paper between the outer limit of the adhesive ring and the corner of the cap, which tabs project downwardly alongside of the neck as shown in Figure 1, when the cap is applied to the bottle and can be readily grasped by a person wishing to remove the cap. By lifting upwardly and outwardly on one of the tabs of the cap, it will be torn loose from the bottle neck and a band or strip will be torn across the top or central portion of the cap dividing it into two parts which can then readily be torn aside and downwardly to remove them from the bottle neck after which the disk-like cap can be removed in the usual manner.

lt'will thus be seen that the present in vention provides a cover or cap which can be readily and quickly positioned on a bottle and which can be removed with facility by the user. By virtue of being pasted down to the bottle neck it offers maximum protection against dirt and germs. It cannot be removed by unauthorized persons without lea? 'ng an indication. By using a gum WlllClI is readily soluble in water the cleaning process at the dairy, before rebottling, remains the same as heretofore, for the application of a small quantity of warm water immediately softens the gum so that the remaining paper falls away from the bottle neck. The gum being soluble in water is not prevented from adhering to the bottle neck in case it is wet with milk which has been spilled over during the filling process.

bottle, said adhesive being of such character and quantity'as to cause adherence of the plaits to, in and of themselves, produce an operative binding and sealing action, in the skirt of the applied cap, around the bottle neck without reliance upon rigidity of the paper or its adherence to the bottle neck.

2. A bottle closureadapted for use by covering the mouthof a bottle and being plaited into a skirt around the neck thereof, and comprising a substantially flat blank of pliable and nonrigid paper-like material of considerable tensile strength, an adhesive which functions by wetting applied to said blank on the inner surface of the intended plaits only on parts of the blank which are to be positioned below the mouth of the bottle, said adhesive being of such character and quantity as to cause adherence of the plaits to, in and of themselves, produce an operative binding and sealing action, in the skirt of the applied cap,

around the bottle neck without reliance uponrigidity of the paper or its adherence to the bottle neck.

3. The combination with a glass bottle having a head and a restricted neck, of a cover-all cap formed of pliable, non-rigid, paper-like material of considerable tensile strength into a central portion covering the bottle mouth and a skirt portion plaited around the neck and bead, adhesive on the inner surface of said skirt and plaits only below the mouth of the bottle, the plaits being of such size and the adhesive of such character and quantity thereon as to provide sufiicient tensile strength in the skirt to, in and of itself, produce an operative binding and sealing action around the bottle neck Without reliance upon the rigidity of the paper or its binding adhesive.

4. The combination with a glass bottle hav ing a head and a restricted neck, of a cover- .all cap formed of pliable, non-rigid, paperli e in and of itself,- produce an'operat-ive binding and sealing action around the bottle neck 10 without reliance upon the rigidity of the paper or its binding adhesive.
