Fig. is a view partly in section and partly in 5 elevation and showing the eyelet of Figs. 13 and 14 in place on a glass rod.

Referring in detail to the drawing, and at firs particularly to Figs. 1 through 12, the improved applicator generally designated Ill is shown as 10 including a glass rod II and a bottle closure I2 mechanically secured to said glass rod as will later more fully appear. In Fig. l the applicator is shown as applied to a bottle 13 including a neck portion 14 having a screw thread or spiral 15 groove l5 therein. It will later become evident that the applicator need not take the particular form shown and that its use is not limited by any particular bottle construction.

In assembling the applicator an eyelete [6 including a tapered tubular body portion I! having a radial flange [B at one of its ends is used. The glass rods I l vary in diameter and are first assembled in the eyelets 16. To take care of rods of different diameters one or more nubs I9 are pressed inwardly from the sides of the body portion of the eyelet It and the nubs or nub extend inwardly tosuch distance that the diameter of the eyelet body between the nubs is less than the diameter of the rod I I. Then, the rod is forced into the eyelet as suggested in Fig. 4, where it will be noted that the rounded end of the rod is just entering between a pair of the nubs 19. As the rod is forced through the eyelet the nubs l9 yield outwardly but tightly hold or grip the rod so that it is firmly attached to the eyelet. Fig. 5 shows the rod in place in the eyelet, and it will be noted in this figure that the nubs 19 have been forced to yield outwardly as compared with their positions in Fig. 4. With this method of assembling the rod in the eyelet the eyelet is prepared to receive rods of varying diameters since the nubs are pressed inwardly to a greater extent than is necessary and the rods must be forced through the eyelets causing the nubs to yield outwardly where they tightly grip or hold the rod. Although these rods are usually of glass it will be understood this means of mounting is not limited to use with rods of this material but may be used with any suitable material.

When the eyelet has thus been secured to the rod the rod is forced through the'eyelet until the upper or outer end of the rod is about flush with the fiange portion 1 8 of the eyelet. Thereafter an inner shell 20 carrying a perforated washer or 55 into engagement with the underside of the flange.

58 of the eyelet [6 as shown best in Fig. 1. The

eyelet fills the opening through the flanged end' of the shell so that the latter is held in concentric relation with respect to the eyeletand the rod Hi.

The opening in the washer or. ring 24 of cork. or the like is somewhat smaller than the eyelet so as to fit tightly about the tubular portion of the eyelet, and this washer has a forced or tight fit between the tubular portion of the washer and,

the skirt-like side wall 2| of the shell 20. Next, acap 2 including-a side wall? 26 and an end wall 21 is forced over the inner shell 29'. The cap. 25v

may be of metal or other suitable material and has a forced fit with respectv to the shell so that when the cap is in place'it. is rigidly-secured to the shell. Further, when the cap: is in place its. end. wall 2'! is against the radial flange I8 ofthe eyeletso that said flange of theeyeletis clamped or held between the flange 2 3 of the inner shell and.

the end wall 27 of the cap.

It will now be understood that the glass rod ll is mechanically secured to the eyelet ['6 and that there is no cement or other adhesive used to secure these parts together. The nub-s f9 have been forced to yield outwardly by the rod H and consequently tightly" grip orhold' said rod so that.

the eyelet is clamped between the flange 23-of theshell 29 and the end wall- 21 of the cap 25.

Since the said cap 25 has a forced fit over theshell 20 it will be appreciated that these parts arerigidly connected and that they are connected without the use of cement or the like, and that the flange I 8 of the eyelet being mechanically clamped or held between the flange 23 of the shell 20- and thewall 21' of the cap- 25 there is no cement or other material tobecome loosened or dissolved by the essential oilsor alcohols inthe contents of the bottle. Further, if cork is used as the sealing material, there is no rubber to rot and release the rod H. to be used with liquids that do not aflect rubber this may be used as the sealing material if desired. The applicator is applied to the bottle by inserting the glass rod l l into the bottle neck and then threading the applicator into place by en gagement of its thread 22 with the thread IS on the bottle neck. This serves todraw the cork or other ring 24 against the outer end of the bottle neck forming a tight seal.

Figs. 13, 14, and 15 illustrate a slight modification of the eyelet construction, and the eyelet of these figures may be used when the-supply of glass rods received comprises or includes rods of unusually small diameter. In these figures the eyelet is generally designated 28 and at its outer or upper end is provided with the usual flange "3 and may in its body portion be pressed inwardly at one or more points to provide the nubs 19 asand for the purpose above explained. Additionally the lower or inner end portion is reduced as' However, if the applicator is by pressing or rolling to provide a bead as at the inner side of the body portion 29 of the eyelet. This bead 3!) reduces the inner diameter of the eyelet very materially and to such an extent that the inner diameter of the eyelet at the bead is 5 less than the diameter of the small rods on which the eyelet is to be assembled.

Fig. 13;, on a greatly enlarged scale, shows the rounded or inner end portion of the rod 5! just entering the bead 3!] of the eyelet 28, and the rod is forced through the eyelet causing the bead to yield outwardly somewhat into the position of Fig. 14 where the body, portion of the glass rod is shown extending through the bead 39 of the eye let- Itwill be clear that this bead portion of the eyelet is tightly gripping the rod so that there is no likelihood of the rod and eyelet separating, and if the eyelet is also provided with the nubs l9 there is. an additional securing of the eyelet to the rod. It is not necessary that the eyelet in each instance be provided with; both the. bead l l and the nubs; lf9 since as shown inthe Figures 1 through. 12 the nubs alone are used. The nubs i9 might be omitted from the eyelet 28 of Figs. 13

through 15, and this eyelet may be. secured; to the red solely; by the internal bead portion of the eyelet. gripping the red. It is to be understood that the rod; with the eyelet 28 is to be secured to a. closure including the shell 2t and the cap 25 and thecork or other seal 24 as in the figures first 30y described; Therefore, in the modified construction the parts are mechanically connected and no. cement or the like is employed.

Having thus set forth the nature of my invention, what I claim is: 35.2

3.. In an applicator, a rod, an eyelet on one end of. the rod and including a tubular portion through which the rod extends, said tubular portion of the eyelet being for the greater portion of its length of a larger internal. diameter than the diameter of the rod and having an inwardly pressed portion causing gripping of the rod by the eyelet, and
