8 Claims. f(cl.221--147) The present invention relates to a closure for the discharge opening of a container for liquids and more specifically to a dispensing closure for such containers by means of which certain quantities of the liquid contents of a bottle, can, or the like may be discharged without removing the closure or cap therefor. g
The invention maybe fully understood from the following description when read in conjunction with the accompanying drawing in which:
Fig. l is a View, in cross section, of a general form of closure according to-the invention.
Figs. 2, 3, 4, 5, and 6 are'views in cross section of closures according to'the invention in which are provided supplementary means for closing'the discharge opening of a container.
Figs. '7, 8, 9, and 10 are illustrative of the forms of openings which may be provided in a closure for the discharge of liquid from the chamber therein.
Referring to Fig. 1, the numeral l denotes a container having an opening 2. A closure 3, engaging the edges 4 of the opening has walls 5 extending above and beyond the opening and a top 6. The closure may be secured to the edges of the opening by any conventional means as shown. It is required however that the joint-[between closure 3 and container I be air and liquid tight, and for that purpose it is preferred, in any event, -to cement the cap to the container. The walls and top of the closure 3 should be of'a resilient material to permit deformation by compression. In a side-wall of the closure a self closing opening, indicated by the numeral 1, is provided for 35 the discharge of liquid from the chamber 8 formed by the walls and top of, the closure above the discharge opening 2,0f the container I. If desired, a button 9 may be disposed on the top of the closure to provide a means by which compression of the cap may be conveniently accomplished. This button 9' may be-separately formed and then joined to the cap or may be formed integrally with the cap.
In Fig. 2 a similar closure arrangement is may be of any similar material which will provide a sealing means as desired. As shown in Fig. 3, the plug II is somewhat elongated, as compared with the plug IU of Fig. 2, extending downward into the opening of the container and having a tapered end to not only guide'the plug. 1?: into the opening, but to initially. provide a passage for liquid around its sides.
Fig. 4 illustrates a plug for the discharge opening of the container, and which plug I2 is substantially spherical and is freely disposed within .101;
the chamber 8 formed by the closure 3 above the opening 2. I
In Fig. 5 the plug i3 is hollow and extends into the opening 2 in the manner of the plug H of Fig. 3. liquid from the container-opening to the chamber 23 is accomplished by means of passageways M in the walls of the plug, above the opening 2, which passageways communicate with the chamber 8 and with the hollow'interior of the a, plug l3, and thereby, with the opening 2. When the cap is compressed the openings of the passageways l4 are closed by the edges of the opening 2. j
Fig. 6 illustrates'a variation of the hollow 15mg 23 sealing means, in which the ends of the hollow plug l5, while terminating above the edges of the opening 2 as does the end of the plug 10 in Fig. 2, are flared outwardly to engage the edge of'the opening 2 when the cap is compressed.
i In Figs. '7, 8, 9, and 10, are illustrated various forms of self-closing openings suitable for discharge of liquid from the chamber 8 upon compression of the closure 3. These openings which are generally indicated by the numeral 1 in the previous figures are respectively indicated in the present figures by the numerals 10L, lb, 10, and 1d. It is intended that, to prevent leakage or evaporation loss in shipment, some form of air tight sealbeprovided for the closure, such as a 40 gutta-percha cap-seal or a strip of such material encircling the closure and covering the discharge opening therein. v
The opening 1a is a vertical slit in a wall of the closure 3 and upon compression of the cap,
the sides of the slit are spread apart to release liquid from the chamber within the closure. The opening 1b is a diagonal slit operating in a substantially similar manner, and the opening 1c is a combined use of vertical and horizontal slits to obtain a greater area for the discharge opening. The opening Id is a combination of a vertical slit with a very small perforation which combination also serves to increase the area of the discharge opening. Of course other forms of PATENT OFFICE I In this instance, however, the flow of 15,5;
self-closing discharge openings may be used if desired.
When using the closure according tothis invention, the container I is first tilted or in- 5 verted to fill the chamber 8 with liquid, then by compression of the closure 'l the liquid in the chamber 8 is expelled through an opening as indicated at 7. v When using a closure provided with deep seating plugs, as illustrated in Figs. 3 and 5, or provided with edge seating plugs, such as illustrated in Figs. 2, 4, and 6, a considerable pressure may be exerted on the liquid in the chamber 3. Therefore, when the liquid in the container is viscid or heavy, such plug means are preferably used.
This invention is not to be limited by the particular details described above for the purpose of illustration, but only by the following claims, in which it is my intention to claim all novelty inherent in the invention as broadly as the prior art permits.
I claim: v l. A dispensing closure for the outlet of a con 25;, tamer-for liquids, comprising a cap of resilient material, including a top portion and a body portion having side walls engaging and extend ing vertically upward beyond the edges of said outlet, a chamber within the cap above the outgo let, and opening downwardly therethrough int-o direct communication with the container, plug means for said outlet dependent within the chamber froinsaid top portion and means for expelling liquid from said chamber by compression of the 35-. cap when the container is inverted.-
2. A dispensing closure for the outlet of a container for liquids, comprising a cap of resilient material, including a top portion, and a" body portion having side walls engaging and extending vertically upward beyond the edges of said outlet, a chamber within the cap above the outlet, and opening downwardly therethrough into direct communication with the container, plugmeans for said outlet integral with 'said top por 45,.tion and dependent therefrom within the chamber, andmeans for expelling liquid from said chamber by compression of the cap when the container is inverted.
3. A dispensing closure for the outlet of a con- 50 tainer for liquids, comprising a cap of resilient material, including a top portion and a body portion having side walls engaging and extending vertically upward beyond v the edges of said outlet, a chamber Within the cap above the out-- let, and opening downwardly therethrough into direct communication with the container, solid plug means for saidoutlet integral with said top into the opening of said container.
5. A closure according to claim 3 in which said a solid plug means has a diameter greaterv than that of the container opening, engaging theedges of said opening in substantially fluid-tight relation when the capis compressed.
6. A dispensing closure for the outlet of a container for liquids, comprising a cap of resilient material, including a top portion, and a body portion havingside alls engaging and extending vertically. upward beyond the edges of said;
outlet, a chamber within the cap above the outlet; opening downwardly .therethrough'into direct communication with the container, hollowiplug means for said outlet integral with said topportion and dependent therefrom within the container, and means for expelling liquid from said chamber by compression of the cap when the container is inverted.
.7. A closure according to claim 6 in which said hollow plug means is a downwardly opening member flared at. its lower end to a diameter great-er than that of the container outlet, and
having an annular lower end which engages the;
edge of said outlet in substantially fluid-tight relation, when the cap is compressed.
8. A dispensing closure comprising a cylindrical body portion of a semi-rigid resilientmaterial; atop portion integral withsaidbody portion; a self-closing port. opening through said body portion; plug means dependent concentrically of theto-p within said body portion;
means for securing said cap in fluid-tight rela tion to the discharge opening of a container;
and means for longitudinal inward deformation of said body portion adjacent the upper end thereof. g
