This invention relates tosam'tary devices; and more particularly to receptacles adaptedto re ceive and discharge liquids, for sanitary use; Such a doushe as d als o l i g" com etions therefor;
A receptacle, such as a douche bag, which may be filled with a liquid such as water, or a water solution including a Small quantity of an antiseptic, soap or' detergent, perfume or the like, and the" contents controllably" dis:- charged, finds frequent use in personal-sanita tion. In the home or the like, where there is considerable space and extensive facilities are ceptacle of this type may be "comparatively'large, since it may be stored in a" closet or' other convenient place, but such receptacles are usually too, bulky, and" cumbersome to be readily carried about. Also, thefacilities' for adetniately filling or preparing the solution to'be'use'cl in'the'receptacle; outside of the'home, are frequently'in' adequate. Thus, it often happens that'theperso'nal comfort or hygiene of a possible user suffers. I

Additional objects and the novel features of this invention will become apparent from the description'which follows. 7
In general, a sanitary device of thjef't'yjpe da scribed, constructedin accordance with this in"- vention, may comprise a' flexible; collapsible bag", having an inlet andjan outletv tube or thelike, in combination with; a filling connection, preferably in the) bag inlet, and having non-return valve therein. The filling connection"mafi compage af si'ngle body oran outer sleeve and an inner body" detachably connected thereto, the inne body being provided with a non-return v valve; details of a-preferred form of the same and otherpart being" shown in the accompany ingdrawings; in which:- r
is a side elevation of asanit'ary device of; the" type described, comprising a bag; and a novel filling'connection, constructed inaccor'dn 'asixnilarlongitudinal secti n, of an alternative 'eri bedirnent of this il'iveliitiblii;
Fig. 5 is a;similar longitudinal sctio'n'of a u her alternati e mbodi t this invn se ia A Fig, 7 isa' iragmentary, longitudinal section of a modified valve construction. H I As; illustrated Figs. 1- -3, asanitary device constructedin; accordance with this invention may comp ise ic lans ba 3 a a d t b f ld d nto: a at com ct si on, ndivi r vided=iwith-aineck ll} adapted to be strctcmnl ov r" he: low r" end; o llin i QOIH B QF- The lower' end ofrthe a is pro i dwitba conventional fitting H; to'which a tube [Inlay be attached, for discharge of liquid; from the bag, the fiow"through"tube l 2 being controlled by a conventionalsnap-acting pincer orthe like (not shown). In general, the fillingconnection IE is adapted to permit thefiowof liquid into, thebag B,- asin- Fig; 2, wherein the, upper end of the filling oonnection F! is held against a water tap on spigotlii'; but after the bag has. been filled, discharge-of the liquid through the filling con,- nectiomFis, prevented, in a manner explained detail-later. As-in-Figi 3:, the sides. lll andedges I5 ofrbag Bs'are preferably preformed to provide folds so that the bag may be folded flat, as shown, and the -tubei.lz2 either-coiled '01 wound" around; the bag, '1 orth'e'bag "B3 and; "tube: 12 wound? sh ut-e1 filling "connection- This provides a compact package, which may be conveniently carried in a compartment of a handbag or the like.
During use, i. e. after filling, it is unnecessary to depend upon the force of gravity for discharge of liquid from the bag B, since the bag may be gently or forcibly squeezed by the hand of the user, as desired. Thus, the bag B need not be positioned at a relatively elevated point with respect to the discharge end of tube l2, and therefore the tube I2 may be relatively short, such as only a few inches in length. Also, due to the non-return valve in filling connection F, there is no possibility of liquid being accidentally discharged through the filling connection during use.
One embodiment of filling connection F, as shown in Figs. 1 to 4, comprises .a cylindrical outer sleeve l'l, over which neck ID of bag B may be stretched, and to which an inner body [8 is detachably connected, as by cooperating threads IS. The neck [8 of bag B slips over the outer sleeve H, and remains connected thereto, while the inner body I8 may be removed from the outer sleeve to permit a detergent, antiseptic, perfume or the like to be placed within the bag B prior to filling, or to permit the bag to be quickly emptied in case all of the liquid is not used. Inner body l8, as shown more clearly in Fig. 4, is provided at its upper end with an upstanding flange 20, which may be knurled around the outside, as in Fig. 1, so that the user may more readily connect and disconnect inner body IS from outer sleeve ll, flange 20 providing a recess in which a washer 2i may be placed. Washer 2i is adapted to seal the lower end of the tap or spigot [3 of Fig. 2, so that it is necessary only to hold the filling connection F againstv the tap it, during filling. Washer 2| may be made of hard or soft rubber, or other material, sufiiciently soft material being preferred so that an effective seal at tap I3 is provided during filling by a relatively small amount of pressure against the tap. If desired, the washer 2| may be cemented or otherwise relatively permanently attached Within its recess. A gasket 22 may also be provided at the upper end of outer sleeve 1?, to prevent any possibility of leakage, the inner edge of gasket 22 being received in an annular recess 23 in body H, to prevent possible loss of the gasket.
The inner body l8, as shown more clearly in Fig. 4, is also provided with a central passage 25 which leads to a well 26 formed in a depending cup 21, the latter being closed at its lower end and provided With one or more series of peripherally spaced holes or apertures 28. Holes 28 are adapted to form a non-return valve, in combination with a suitable closure, such as a tube 29, form-ed of rubber or other suitable elastic material stretched over the outside of cup 21 and distensible under water. or liquid pressure from well 26, as in Fig. 2. As indicated by the arrows of Fig. 2, water from tap l3 flows into well 26 and through holes 28 into the interior of bag B, the pressure of the water forcing the tube 29 away from the outer wall of the cup 21 below the holes 28. As will be evident from Fig. 4, after the ba is full of water, as to a level 30, no water will discharge from the bag through the filling connection, since the tube 29 seals the holes 28, due to the pressure of water on the out side thereof.
In the embodiment of this invention illustrated in Fig. 5, a single body I8 is provided, the outer sleeve being omitted and body l8 being 4. provided with an outer shoulder 32' over which the neck [0 of bag B is stretched. Outer shoulder 32 may be provided witharr inwardly tapered groove 33 at its upper end, into which the upper end of neck [0 of bag B extends, to cause neck ID to cling more securely to the connection. Similar to the body l8 of Figs. 2 and 4, the body l8 of Fig. 5 is provided with a central passage 25 leading to well 26 formed in depending cup 21, the latter having holes 28 and forming a nonreturn valve with a tube 29'. If desired, the lower end of tube 29' of Fig. 5, may be preformed so as to form a fiat, normally closed flap 34 at the lower end, which will open upon the discharge of liquid therethrough.
Body l8 of Fig. 5 is provided with an inwardly tapered recess 35 at its upper end, in which a generally annular washer or cushion 36, formedv of soft foam rubber or the like, and having an upper inwardly tapering surface, is relatively permanently attached, as by cementing, preferably with a waterproof cement or adhesive. The washer 36 is adapted to accommodate taps or' spigots of different sizes, such as the slightly larger tap l3, the end of which is pressed into the relatively soft material of Washer 36, as shown. As before, the bag is filled by pushing washer 36 at the upper end of the filling connection against tap or spigot I3, which causes the water or liquid to flow into well 26, out holes 28 and underneath tube 29', into the interior of the bag. When the outer sleeve is omitted, as in Fig. 5, antiseptic tablets or other material to be added to make up a desired solution in the bag, may be placed in the well 26, where they will tend to dissolve, and/or be carried through the holes 28 into the bag. Also, as before, after the bag has been filled to the desired level, the water or solution may be forced through the tube connected to the lower end of the bag by pressure on the bag, the non-return valve tube 29' preventing the water or solution from being discharged through the filling connection.
The embodiment illustrated in Fig. 6 includes an outer sleeve 40, an inner body 4| and a filling spout 42, the latter preferably being made of soft rubber or the like and cemented to or formed on and thereby attached to inner body 4| about a, dovetail joint 43. Filling spout 42 has a relatively long, inwardly tapering recess or inlet 44, so that a user may more readily hold the spout against and around the tap during filling. The lower end of spout 42 is also provided with an outwardly tapered surface which forms a sealing joint 45 with the inwardly tapered upper end of sleeve 49, the latter being attached to inner body 4| by threads l9, and adapted to be unscrewed therefrom to enable antiseptic tablets or other material to be placed in the bag prior to filling.
The remainder of the construction illustrated in Fig. 6 is similar to that of Figs. 2 and 4, except that outer sleeve 40 may be provided with an exterior groove 46 in which neck in of bag B fits to form a more secure joint, when neck I0 is stretched over the outer sleeve. Inner body 4! is provided with a central passage 25 leading to a well 26 in an elongated cup 21', the latter being provided with only one set of holes 28', normally covered by rubber tube 29, which may also be constructed in the same manner as tube 29' of Fig. 5. To hold tube 29 more securely on cup 2'1, the latter may be provided with a groove 41 into which the upper end of tube 29 extends, the constriction of the upper end of tube 29 in groove 41 insuring the flow of water through the lower end of tube 29, and the retention of tube 29 on cup 21" under relatively high pressure conditions.
'Cup 21 of Figs. 4 and 5 may be provided with a groove similar to groove '4'! of cup 21' of Fig. 6, or, as in Fig. 7, cup 21 may be provided with a series of exterior projections 50-, located above holes 28, for the same purpose. As will be evident, cup 21 of Fig. 6 may be provided with projections 50 in lieu of groove 41.
From the foregoing, it will be evident that the sanitary bag and filling connection therefor of this invention fulfill to a marked degree the re quirements and objects hereinbefore set forth. The combination of a readily collapsible bag, with a filling connection having a non-return valve therein, permits the discharge tube to be 'made relatively small in length, so that the bag and tube may be folded or otherwise assembled in a small, compact package readily carried in a compartment of a handbag. Also, a filling connection having a suitable sealing device, such as the washer 2| or 36, or spout 42, permits the bag to be filled conveniently from an ordinary water tap or spigot, and also permits the bag to be partially filled with hot water from one tap, and then cold water from another tap, or vice versa, to produce the desired temperature of solution. A filling connection having an inner body readily removable from an outer sleeve, the latter being adapted to receive in sealing engagement the neck of the bag, permits an antiseptic, detergent, perfume or other material to be placed in the bag prior to filling. Also, as indicated previously, when the filling connection is provided with a well formed in a depending, elongated cup, the antiseptic or the like may be placed in the well, to be dissolved by or washed into the bag during filling. The preferred form of non-return valve is very simple in construction, yet operates effectively to permit the bag to be filled readily and prevent the discharge of the contents through the filling connection during use, as when the bag is squeezed in order to cause the contents to fiow out through the discharge tube.
V Various materials may be utilized in makin a filling connection constructed; inaccordance with this invention, the bagB, of course, being made nomically, may also be utilized. The valve tube 29 or 29 is, of course, madeo f resilient material suchasrubber, either natural or' synthetic, while the "gasket 22 may be made of natural 'ors'ynthetic rubber, or other plastic. The washer 2|, adapted to engage the filling tap or spigot, may be made of hard or soft rubber, as indicated, while the washer or cushion 36 and spout 42, which are interiorly tapered, are preferably made of a soft foam or cushion rubber or the like, as indicated previously. It will be understood, of course, that various other materials may be utilized.
It will also be understood that various changes in the size, shape or configuration of the parts may be made. For instance, cup 21 or 21' need not be annular in shape, although an annular shape is normally preferred because of its simplicity in production, since the cup may be square, hexagonal, or have other cross sectional shape, either regular or irregular. Also, the number and position, as well as thesp'acing, of holes 28 or 28' may be varied considerably from that shown. Other types of collapsible bags or recepta'cles may be used, as well as other types of non -return valves, such as a spring pressed-metal or plastic disc or bulb acting against a suitable seat. In addition, other types of joints between an inner body and outer sleeve may be utilized, as well as different sealing means.
While different embodiments of this inven tion and variants of certain parts thereof have been illustrated and described, it will be understood that other embodiments may exist, and other different variations may be utilized, without departing from the spirit and scope of this invention as defined in the appended claims.
