3 Claims. (Cl. 2151) This invention relates to improved handle structures for fused vitreous containers, and particularly glass bottles' whose size ,or filled weight are such as to impose considerable load on the handle and its connection with the bottle.' Especially desirable are greater strength and convenience of use, in handles for relatively larger bottles containing liquid hypochlorite bleach .or other liquids capable of causing damage by the handle and bottle breakage. e

Heretofore' such bottles commonly have been made with handles in the form of loops fused to the neck position of the bottles, the loops being of such size and formation that the heavy weight of the bottle and its contents is taken by afinger' inserted through the loop; Such concentration of thet-weight renders the bottles tiresome and inconvenient to carry as well as to manipulate in household use. Also, handles with such loop configuration can impose structural weaknesses, particularly at their junctures with the bottle necks, especially unless sharp or'abrupt angularities or irregularities (at which strain concentrations can occur) are avoided.

Our primary object isto provide anew form of associated handle and bottle neck, having important structure and functional advantages overall prior structures of which I am aware. In accordance with the invention such association of the handle and neck involves forming the neck portion of the bottle with a projecting rim molded and fused integrally with the neck and handle. As will appear, the handle projects laterally from the neck ring, and preferably has a free grip length extending downwardly and in overlying spaced relation to the shoulder of the bottle below. It has been found that by so forming the handle and in the later described and illustrated shape and dimensional relation to the neck ring, it is possible to give the handle, notwithstanding its free extent, greater strength, load carrying capacity and resistance to break-oft" from shock or impact, than many of the conventional loop handles heretofore used.

As indicated, added to this structural advantage are the functional benefits of enabling the bottle to be more easily and conveniently carried and handled .by reason of the permissible grasp and the handle angularity which tes PatentO contributes to better balance of the bottle both while being carried and tilted for pouring.

This invention contemplates various additional objects and innovations, including such features as internal recessing of the neck ring, and forming the handle with a hollow interior opening from the neck recess.

All these, together with the aforementioned features and objects, will be understood most readily from the following detailed description of certain illustrative embodiments of the invention shown by the accompanying drawing, in which:

Fig. 1 is a View showing in side elevation the upper portion of a glass bottle embodying the invention;

Fig. 2 is a fragmentary plan of Fig. 1;

Fig. 3 is a cross-section on line 3--3 of Fig. 2; and

Fig. 4 is a view similar to Fig. 1 illustrating a variational form of the invention. e 1

Referring first to Fig. 1, the circular cross-sectionbody 10 of the bottle is shown to have, except for the later described recess, a usual shoulder formation 11 tapering upwardly tothe neck portion 12, the top of which is threaded at 13 for reception of a cap, not shown. In this form of the invention the shoulder area 11 of'the'bottle is shown to contain a recess 14 extending downwardly from the neck 12 to a location near the full-diameter surface-of the bottle at l5, the recess and specifically its base surface 16 being vertically concave in the axial plane of the bottle coincidentwith the section line 3-3 of Fig. 2, and also being transversely concave in horizontal planes of the bottle shoulder, as represented by the convergent spacing of lines 16 and 17, the latter representing the bottle surface at the transverse limits of the recess at which the surface of the recess has gradual and smooth mergence with the shoulder 11;

The neck portion 12 is molded with an integrally fused externally projecting annulus orring 18, the latter being shown to be defined between a top surface or shoulder 19 preferably curved at 20, and a-lower shoulder or line 21, the ring preferably having a downward taper substantially as illustrated. Between the ring 18 and threads 13, the neck has a short straight-extent'22 which may be overlapped by the cap skirt. In Figs. 1 to 3, the ring is shown to have an internal annular recess 23.

Formed-integrally with the ring 18 is a handle 24 which preferably is shaped substantially as illustrated to have a free downwardly and outwardly inclined extent directly overlying and spaced from the surface of the recess 14, the handle being centrally and symmetrically aligned with the recess, see Fig. 2. The handle is shown to correspond in thickness at its juncture with the bottle neck, with the width or vertical dimension of the ring 18, and to be so related to the ring that the top surface 25 of the handle is substantially a continuation of the shoulder 19. The undersurface'of the handle at 26 is insubstantial alignment with the bottom shoulder or extent 21 of the ring, and-at its transverse center, the handle has a curved strain minimizing juncture 27 with the bottle neck. The handle may be molded or otherwise formed with a hollow interior 28 in open communication or merger with the neck ring recess 23. Weightcarrying and shock tests have proven that although of hollow formation, the handle by reason of its described and illustrated shape characteristics and integrally fused relation with the ring 18, is capable of safely carrying the loaded weight of the bottle, and of withstanding all :hocks normally to be encountered even under bottle oad.

The handle is given sufiicient downward and outward extent to permit its being grasped at the grip recesses 30 by a major width of the fingers, thus giving comfortable distribution to the bottle weight when it is being carried. The same characteristics of the handle render convenient any manipulations of the bottle for household use, as when pouring out its contents, by reason of both the handle angularity and extent. In further reference to the handle location and angularity, a balanced feel in carrying the bottle results from a comfortably acquirable alignment between the handle and the center of gravity of the bottle and its contents.

The recessed configuration of the bottle shoulder in the form of the invention shown in Figs. 1 to 3, affords a further advantage in that the spacing at 31 between the handle and the surface of the recess, while ample for free insertion of the fingers, is sufficiently limited to permit the back of the fingers to bear against the surface 16 and to give support for the fingers against both the handle Patented Apr. 22, 1 58 and the bottle proper. The recessed shoulder feature of the bottle is more specifically dealt with in a copending Sterges application, Serial Number 664,298, entitled Bottle Structure and filed on even date herewith.

Provision of the internal neck ring recess 23 has the functional advantage of rendering the bottle less likely to drip. As the bottle is being returned to an upright position after pouring, this recessed space provides a pool of liquid remaining in communication with the stream beng broken at the mouth of the bottle, and thus causes a surface tension effect tending to draw back into the bottle the last drops that break from the poured stream and do not fall away from the bottle.

The variational form of the invention shown in Fig. 4 is similar to the described embodiment except that here the handle is carried by the neck portion 33 of a differently shaped bottle, the latter in this instance having a relatively extended neck portion 34 more abruptly departing from or intersecting the shoulder 35. The handle 36 is fused integrally with the ring 37 substantially as described before, and the free end of the handle overlies in spaced relation the neck extent 34 and shoulder 35. In this instance the handle is shown to be formed solidly and the neck ring 37 to have its bore 38 running straight and through the portions 39 and 40 of the neck corresponding to 22 and 13 in Fig. 1.

We claim:
