Background of the Invention
This invention relates to a bottle having a clip for suspending the bottle in an inverted position. It relates particularly to bottles that are used to dispense detergent into a toilet tank.
A number of types of suspending devices for liquid dispensers have been suggested. For example, see U.S. Pat. No. 2,839,763, showing a hook-type suspension device which is positioned over the top of a toilet tank wall and which clamps onto the neck of the bottle. U.S. Pat. No. 3,023,426 shows another type of fixed hook member supporting a cage basket into which the bottle fits. U.S. Pat. No. 3,769,640, shows bendable wires forming a hanging device. These devices are all cumbersome, involve hangers that are separate entities from the bottle, and complicate installation. Also, they are relatively expensive.
U.S. Pat. Nos. 3,627,177, 3,698,021, 3,864,793, and 3,952,339, show devices which are assembled with the bottle. These involve a sliding member, usually metal, that slides in a recess in the bottom wall of the bottle, and requires stops. They are somewhat tricky to assemble and tend to be stiff in their action.
U.S. Pat. No. 3,841,524 to Easter disclosed pivotal dispenser bottle hanger including a flexible plastic hanger member secured permanently to the bottle wall, within a shaped recess, by suitable bonding means. The hanger member had a grooved fold line so that it could pivot to be rotated outwardly 90.degree. from a stored position to an extended, bottle-suspending position. This risked being broken off by flexure.
While these prior devices were for the most part effective for their intended purpose, none was as efficient, dependable, easy to use, and as economically manufactured and assembled as the present invention described below.
Summary of the Invention
The bottle hanger of the present invention is simple in manufacture, assembly, and operation, yet at least as effective and dependable as prior devices in service. A single hanger component is required, and in assembly it is simply snapped into place in the dispenser bottle wall, with no gluing or other type of adhereing or fastener means required. In storage prior to use, the bottle retains the hanger closely against its side, contained in a recess and generally flush with the remainder of the bottle wall. The shape of the hanger member is such that it enables pivotal movement through 90.degree. only, from the stored position to an extended position generally parallel and flush with the bottle's bottom.
In addition, protruding structure on the recess walls of the bottle interferes with over-rotation, beyond the 90.degree. extended position, to further prevent forced rotation beyond the intended position.
In use, the hanger rests on the top edge of a wall member, such as the wall of a toilet tank, so that the bottom of the inverted bottle does not extend appreciably higher than the hanger itself. In the case of a toilet tank, this avoids interference with tank top closure. To retain the bottle in position against the wall member, a lip or flange on the end of the hanger member extends downwardly over the edge of the wall member.
Accordingly, in an embodiment a suspending device according to the invention for an inverted dispenser bottle comprises a hanger member for suspending the bottle over the top of a wall member against which the bottle is to be positioned; means associated with the hanger member and a wall of the bottle for pivotally mounting the hanger member on the bottle such that the hanger member rotates about a horizontal axis at a pivoted end, from a stored position adjacent the bottle wall to an outwardly extended position generally perpendicular to the bottle wall, said axis being near the upper end of the suspended bottle; means for limiting the outward rotation of the hanger member to said generally perpendicular extended position; lip means on the outer end of the hanger member, opposite said pivoted end, extending toward the bottle wall when the hanger member is stored, for holding the bottle close to said wall member, limiting movement of the bottle's upper end; and recess means in the bottle wall providing for substantially flush storage of the hanger member in the bottle wall.
As discussed above, among the objects of the invention is to provide a simple yet efficient dispenser bottle suspending device which is easily and quickly assembled, which may be stored compactly with the bottle, and which is easily operated and dependable in service. These and other objects, advantages, and features of the invention will be apparent from the following description of a preferred embodiment, taken in conjunction with the drawing.

Description of a Preferred Embodiment
In the drawings, FIG. 1 shows a liquid-dispensing bottle 10 suspended on a wall member 11, such as a wall of a toilet tank 12 as shown, by a hanger member 13 connected to the bottle 10.
As shown in FIG. 2, prior to its installation, the bottle 10 is normally stored or displayed upright. It has a bottom wall 14, four upright walls 15, 16, 17, and 18, and a neck 19 leading to an opening 20 containing a suitable dispensing valve 29, such as the one shown in U.S. Pat. No. 3,841,524. At this time the bottle is usually capped, by a cap 21, which is removed for installation, and the hanger member 13 is substantially flush with the wall 15, this wall 15 having a recess 22 for reception of the hanger 13.
FIG. 4 shows in sectional view the hanger member 13 in an extended position, pivoted outwardly from the bottle 10. The stored flush position of the hanger member 13 is shown in dashed lines. The recess 22 is shaped, as shown, to accommodate a lip or flange member 23 of the hanger 13, which extends at about right angles from the end of a generally planar portion 24. In the extended position, the lip 23 fits over the top edge 25 of the wall member 11, extending downwardly as shown, to prevent the bottle 10 from pulling away from the wall member 11 upon which it is suspended.
As indicated, the hanger member 13, in the extended position, is approximately parallel to and flush with the bottle's bottom wall 14, which is the upper end of the bottle 10 in the suspended, inverted position. This enables installation of a tank top 26 or other such cover, which normally rests on top of the wall member 11, to fit in place without any greater interference than the thickness of the planar main portion 24 of the hanger member causes, i.e., the bottle itself does not interfere with the placement of the cover 26.
The components 13 and 10 of the invention are shown prior to assembly in FIG. 3. As indicated, the lip means 23 may comprise a pair of separate depending flanges 27 and 28, for economy of material. Connected at the other end of the generally planar main portion 24 is a pivoted end portion 30, including a generally planar flange 31 stepped downwardly from the portion 24 by a transverse flange 32, a pair of vertical ribs 33 and 34 which act as a stop means for the extended position, and a pair of outwardly extending nipples 35 and 36. The nipples 35 and 36 fit into sockets 37 and 38 of the bottle 10.
The nipple sockets 37 and 38 are preferably simple depressions formed in parallel, spaced side walls 40 and 41 of the recess 22 of the bottle wall 15. Upon assembly, the hanger member 13 is simply pushed into place in the recess, whereupon the resilient plastic of the member 13 and of the bottle 10 yields and temporarily deforms to permit the nipples 35 and 36 to reach the sockets 37 and 38, at which point they snap into place. The sockets 37 and 38 of the bottle walls 40 and 41 exert a continuing axial force on the nipples 35 and 36, and the pivoted end portion 30 of the hanger member, so that a mild degree of frictional resistance to pivoting movement of the hanger member is afforded. This maintains the hanger member 13 in the stored position before the bottle is ready for use, and maintains it in the extended position when the bottle 10 is being moved toward placement on the wall member 11, adding to the convenience and efficiency of the apparatus.
As shown in FIGS. 2 and 3, the recess 22 includes a deeper groove or depression 42 for accommodating the lip means 23 of the hanger member in its stored position (in dashed lines in FIG. 4).
In the extended position, as shown in FIG. 4, the hanger member 13 is at about 90.degree. rotation from its stored position. The stop ribs 33 and 34 are flat at their ends and abut against the surface 43 of the recess 23 of the bottle wall 15. Since these stop ribs 33 and 34 are above the horizontal axis of rotation of the hanger member, they prevent further pivoting movement of the member beyond the extended position shown.
There is preferably provided further structure for preventing forced over-pivoting of the hanger member 13, which would deform and damage the components as well as prevent proper suspension of the bottle on the wall member 11. This structure is best seen in FIG. 3, and comprises a pair of bulges or protrusions 44 and 45 formed on the walls 40 and 41 at the outer corners of the recess 22. If the hanger member 13 is forced a few degrees of rotation beyond its normal fully-extended position, the edges of the planar flange 31 contact the protrusions 44 and 45, arresting further rotation. Thus, it would take a considerable amount of deliberate force to pivot the hanger signficantly beyong the intended 90.degree. extended position.
The above described preferred embodiment provides a dispenser bottle suspending device which is relatively simple, easily and economically manufactured and assembled, compact in storage and convenient to operate. Various other embodiments and variations to this preferred embodiment will be apparent to those skilled in the art and may be made without departing from the spirit and scope of the following claims.
