Description:
In applicant's prior U.S. Pat. No. 2,664,893, there was shown a douche kit that included a syringe, a plug, and a flexible bag unit, with the units being capable of quick connect and disconnect with each other as to permit collapsing of the same into a convenient package for travel purposes.
While the aforementioned douche kit has proved satisfactory in several respects, the manufacture of the connecting means has proved especially bothersome since the interrupted threads were of necessity molded and then permitted to harden followed by the necessity of rotating the same before mold release could be achieved.
Additionally, while applicant's prior patent contemplated a seal of sorts, it was found in use that the seal would not operate effectively with the result that spillage oftentimes occurred to the discomfort and displeasure of the user especially since the threads of the aforementioned prior U.S. Patent did not serve as a point of primary seal as in the present case.
Production of an improved disposable douche unit having improved sealing and connecting features is the principal object of this invention with other objects of the invention becoming more apparent upon a reading of the following brief specification, considered and interpreted in the light of the accompanying drawings.
OF THE DRAWINGS
FIG. 1 is a perspective view illustrating the improved douche unit in assembled form.
FIG. 2 is a vertical section taken on the lines 2--2 of FIG. 1.
FIG. 3 is a horizontal section taken on the lines 3--3 of FIG. 2.
FIG. 4 is an exploded view, partly broken away and in section, and illustrating the structure of the connecting and sealing means in larger detail.
FIG. 5 is a view similar to FIG. 4, but done in perspective and illustrating a modified form of the invention.
Referring now to the drawings and in particular to FIG. 1 thereof, the improved douche kit, generally designated by the numeral 10, includes a stem portion 11, a plug portion 12, and a flexible bag portion 13, with the arrangement being such that the plug serves as a point of temporary attachment with respect to the stem 11 and the bag 13 which may be removed therefrom for storage or transportation purposes.
The stem 11 is generally elongate in nature, and includes, in one end thereof, a series of perforations 14,14 that communicate with a hollow interior passage 15 (see FIG. 2) so as to, in effect, communicate the perforations 14, 14 with the connecting end 14a as will now be described with reference to FIG. 2.
The end 14a includes an end wall 16, into which the bore 15 opens, as clearly shown in FIG. 2. The diameter of the end wall 16 approximates the diameter of the stem 11 in its central region, and spaced inwardly from the end wall 16 is a bell-shaped portion 17 that includes an annular lip 18 which terminates in a knife edge point 18a as clearly shown in FIG. 2 of the drawings. A tapering wall surface 19 extends radially inwardly along the axis of the stem 11 and terminates in a shoulder 20 as clearly shown in FIG. 2 of the drawings.
Referring now to FIG. 4 of the drawings, the wall portion adjacent end 16 has provided thereon a pair of radially outwardly projecting ribs 21 and 22, with the ribs 2- and 22 both being preferably V-shaped in cross section and both being almost semi-circular in planar configuration with each rib having a radial sector of about 150° to 180° and with the ends of the ribs being spaced circumferentially from each as shown in FIG. 4. As shown from FIG. 3 and FIG. 4, the ribs are in opposed helical relationship with each other, with the rib 21 constituting a portion of one of the two threads making up the double pitch arrangement shown. Similarly, the rib 22 is a portion of the remaining thread of the double pitch interrupted thread. By this arrangement, the lead points of the threads 21 and 22 are disposed from each other by approximately 180° , with the pitch or lead of the threads 21 and 22 being axially aligned and equal.
Again referring to FIGS. 2 and 4, the plug member 12 is a circular configuration and includes an inner bore 30 and an outer peripherally extremity 31, with the extremity 31 terminating in a tapered surface 32 that includes an annular recess 33 that terminates in the reduced external wall portion 34 as clearly shown in FIGS. 2 and 4 of the drawings. The end wall surface 35 is somewhat dished in configuration so as to terminate in a male knife edge projection 36, with the knife edge projection further including a tapered surface 37 that is complimental in nature to the surface 19 for sealing purposes. Opposed bottom wall 38 extends between the circular wall surfaces 30 and 34 as clearly shown in FIG. 4 of the drawings.
The plug 12 also includes connecting means and in this instance these connecting means are defined by a pair of substantially semi-circular radially inwardly projecting ribs 39 and 40, with the ribs being generally similar in configuration to the previously described ribs 21 and 22 so as to cooperate therewith for locking purposes. Accordingly, the rib 40 is a semi-circular helice portion of one of the two threads making up the double pitch thread shown, while the rib 39 constitutes a semi-circular portion of the remaining thread in the double pitch thread shown. These threads are aligned in opposed relationship to each other to substantially define a circular thread pattern with the pitch of the threads 39 and 40 being axially aligned and equidistance.
Here, however, the ribs 39 and 40 preferably extend through a full 180° sector for mold release purposes, although it is to be understood that some radial or circumferential spacing between the ribs 39 and 40 is possible.
The bag 13, as best shown in FIG. 2, is of a collapsible thin wall type of construction and includes a beaded portion 42 that defines the mouth opening thereof, with the portion 42 being stretchable so as to be seated within the cavity 33 as is apparent from FIG. 2.
In use or operation of the improved douche kit, it will first be assumed that the bag 13 has had the beaded opening 42 thereof snapped into place within the recess 33 of the plug 12, and at this time the unit may be filled with the appropriate solution, following which the stem 11 may be inserted into the bore 30 of the plug 12 for locking purposes. During such locking process, and referring to FIG. 4 for example, when the telescoping just described occurs, the lower surface of the "low" end of thread 21 will be seated on the upper surface of the "low" end of thread 40 while the high end of thread 22 will be seated on the high end of thread 39. As clockwise twisting occurs, the thread 21 will move under the high end of thread 39 while the low end of the rib 22 will move under the high end of rib 40.
As rotation continues, absolute locking in place will occur, with it being noted that as rotation continues, each rib will be secured throughout a portion of the extremity on opposed sides by the ribs of the opposite component part in question. Stated otherwise, at final connection, the ribs 21 and 22 will be on opposed sides of the ribs 39 and 40 because of the novel, unique, double helical arrangement that has been employed.
It will also be noted that as the telescoping action just described occurs that there will be a meeting of the surfaces 19 and 37 for sealing purposes and further, that these surfaces and their sealing action will be augmented or supplemented by the fact that the rib 36 will be deformed by the lip 18 vice versa as continued telescoping continues as a result of continued rotational movement that draws up the unit 11 within the unit 12.
At such time as the assembly is complete as just described, it is believed obvious that the instrument may be operated in normal fashion for the purposes intended, following which it may be readily disassembled, readily cleaned, and then the bag disposed of if this be desired.
With reference to the modification shown in FIG. 5, the only difference is that each thread 21a, 22a, 40a, and 39a, extend for a full 180° instead of the approximately 160° - 170° shown in FIGS 1 through 4. Otherwise, the operation is the same.
While a full and complete description of the invention has been set forth in accordance with the dictates of the Patent Statutes, it is to be understood that the invention is not intended to be limited to the specific form herein shown.
Accordingly, modifications of the invention may be shown without departing from the spirit hereof or the scope of the accompanying claims.
