Patented May 19, 1942 I UNITED STATES PATENT OFFICE SYRINGE APPLIANCE Michael E. Demscy, Cleveland, Ohio Application July 19, 1940, Serial No. 346,297
4 Claims.
My invention pertains to a syringe appliance to be used by itself, if of suitable size, or in combination with a support through'which' it may syphon or discharge and which support might be possibilities for enduring color variation both of the rubber syringe and of the support which is perhaps to be formed as a molded plastic.
Adverting to the drawing:
Figure 1 is an elevation of my appliance, partly broken away, mounted on a bottle top.
Figure 2 is a diametrical sectional view of Figure 1.
Figure 3 is a bottom plan view of my syringe appliance detached from the bottle neck.
Figure 4 is a perspective view of a modified form of the syringe by itself, circumferentially arranged radial projections appearing substituted for an inner flange of annular shape as shown in Figure 2.
Figure 5 is a View corresponding to Figure 2, illustrating a further modification, alike of the syringe proper, of the carrying support and of the manner of efiecting detachable connection with a bottle or other container.
A concave-convex eye-cup l is of conventional shape except that its central or head portion 2 is provided with a central aperture 3 and except further that it is provided interiorly with (as exemplified, integral therewith) an annular flange 4 which'is completely enclosedby the eyeguard or cup and projects toward its larger and permanently open end. The flange 4 is internally fashioned with screw threads 5 adapted to an eye-cup or abottle closure. 5 cooperate with external complemental screw The subject matter of this application constithreads 6 around the neck 1 of a bottle whereby tutes a continuation in part from the disclosure the annularfiange 4 may serve thefunction of of my application entitled, Medication applia bottle-cap closure. The aperture 3 is defined ance, filed August 12, 1939, Serial No. 289,886, by an annular flange 8 lying'in a plane perpennow Patent No. 2,209,192, dated July 23, 1940. 10 dicular to the longitudinal axis of the cup to pro- In that identified patent, both the syringe vide an inner annular surface!) which extends structure and the support are composite or asradially outward to the cap 4. The purpose of sembled; however an integral eye-cup and screw the annular surface 9 presently will be explained. cap, though illustrated, is not claimed. The The structure described-in t is pa a W originations herein disclosed, while comprehendbe composed, as currently contemplated,'of' a ing the same'principles of function,-are improveplastic or other moldable substance like rubber ments principally based on commercial c'onsidor Celluloid. erations and involve integrality not only of a An t l Syringe Structure necessarily combined eye-cup and bottle cap enclosed there- 0W, s b e uc y c iw a d by, but also integrality of the syringe proper 2Q ma ke ed s a o p s n f so andv lfleadily which in its entirety is exemplified as composed distortable or deformable rubber. It comprises of a soft; m ld d r bb r, a short neck portion I I intended to have a snug, The primary object of my invention has be frictional fit within the aperture 3, an exterior to provide a uniquely compact syringe structure, Shoulder flange Which as a lat surface economical of manufacture and more readily aS- for abutment against the eXteriol, u a Su sembled with a support, whether the latter be an face of the head 2 and an interior, e n apertured eye-cup, an apertured bottle cap or .fiange l3 of slightly smaller circumference than a, combination of both cup and cap r bithe radially outward circumference of the annation of an eye-guard and bottle stopper. A 11111311 Surface The inner Syringe flange 3 is further object has been a realization of extended thin enough to permit of its folded displacement or temporary distortion to smaller compass preparatory to pressing it through the aperture 3 and permitting it to expand to its normal position in which it appears in Figure 2 and in 5 which position it is resiliently clamped against the annular surface 9. The length of the neck ll' of the syringe, being about the same or a modicum shorter than the thickness of the annular flange 8 of the head of the eye-cup, accomplishes such a yielding clamping action of the eye-cup head between the spacedly appositioned flanges of the syringe. When attached to a bottle neck, the inner syringe flange [3 will become squeezed against the lip of thebottle whereby advantageously to serve the additional function of a sealing gasket. A lining tube [4 extends through the hollow syringe structure and into the confines of a hollow bulb partially defined by a thin, readily flexed and top diaphragm l5, whereby the ordinary functions of a syringe, eitherto syphon or to discharge, may be exercised.- As
shown, the lining tube is composed'of glass, but other materials would obviously satisfy. The inner end [6 of the lining tube preferably projects a short distance inwardly beyond theinner flange l3 to improve the dropwise deposition of any fluid which has been earlier syphoned into the bulb, and the opposite end of the lining tube I4 is supplied with a flaring bead ll conforming to the approximately hemispherical side of the bulb which is opposite the diaphragm l5.
The modification illustrated in Figure 4 consists in the substitution for the inner flange 13 of annular form, of a plurality of radial projections l8 somewhat more readily deformed to facilitate the projection thereof through the aperture in the support. The clamping attachment of the syringe is similarly to be effected by the operation of an outer flange or shoulder 19 and diaphragm cover 20. v
The modification of Figure involves an elimination of the interior screw cap because the construction is intended for attachment to bottles a hollow interiorly threaded cup-shaped member purposed to serve as a bottle closure and an eye guard of comparatively larger concavo-convex form enclosing and secured to the central portion of said member, said structure being provided with a central aperture for introduction of a syringe nozzle and a syringe closure for said aperture.
2. The combination as an integral structure, of a member intended to serve as a closure for a container, a concavo-convex eye-cup enveloping said member in spaced relation thereto, said structure being provided with a central aperture for introduction of a syringe nozzle and syringe means for closing said aperture.
3. The combination of an eye cup alternatively adapted to enclose the entry of a fluid container and provided with a central opening, a rubber which are not provided with screw-threaded necks. An eye-cup 2| has an apertured head 22; a syringe structure has a relatively short neck whose length corresponds to the thickness of the head 22, only an exterior enlargement provided with a flat surface 24 abutting the outer side of the head; 'a longer liningtube 25 occupies the hole 26 of the syringe, but projects a greater distance therefrom into the eye-cup; a rubber stopper 21 having a bore 28 is adapted for frictional envelopment of most of the projecting end of the tube until it abuts the inner side of the head 22 at 29 while a bottle neck 3.0 is adapted snugly to receive the stopper.
It is to be realized that the novel scope of my invention comprehends many equivalent variations of structure if exercising the same function. The showing of the drawing and the particular descriptions are merely specific exemplifications of a plurality of readily conceivable modifications.
I claim:
1, The combination as an integral structure, of
syringe structure comprising a neck occupying said opening and further comprising radially outward projecting means on the inside and outside of said cup respectively for clamping said syringe structure to said eye cup and a lining tube fitted in said neck and projecting beyond the cup-enclosed end thereof.
4. The combination with an eye-cup provided with a central aperture, of a rubber syringe structure integrally comprising; a neck adapted to occupy said aperture, intermediately of itsends an annular flange abutting the outside of said eye-cup around its aperture, a flexible diaphragm formingin conjunction with said intermediate section a bulb adapted to syphon and to discharge fluid through said neck and eye-cup and at the inner end of said neck radially outwardly projecting means cooperating with said flange to clamp the syringe and eye-cup together; and means within the eye-cup adapted to serve as a bottle closure.
MICHAEL E. DEMSEY.
