Oct. 5, 1954 E. s. TUPPER DISPENSING CLOSURE Filed May 8, 1950 EEL 1S. TUPPER IN VEN TOR. BY

Patented Oct. 5, 1954 UNITED STATES ATENT OFFICE 4 Claims.

This invention relates to dispensing closures for containers such as bottles, cans and the like.

An object of this invention is to provide a dispensing closure comprising a stopper cap which is integrally connected by a exible member to a tubular insert, the flexible connecting member holding the stopper cap in operative position on the container or in inoperative position outside the container.

Another object of this invention is to provide a dispensing closure comprising an insert member insertable into the neck of a container, the said insert member having an abutment collar which limits its movement into the container, and the said closure comprising a connecting member extending from the abutment collar and being of a length to align the stopper cap with the insert member when the stopper cap is brought down into closing position on the container.

Another object of this invention is to provide a modied stopper cap having a, tapering plug adapted to seat inside the neck of the closure to provide sealing contact with the container when the stopper is brought down into operative relation with the tubular insert.

Another object of this invention is to make the outlet end of the closure in the form of a circular rib and to make the stopper cap with a circular cavity so that sealing contact is provided between the stopper cap and the closure when the said rib and circular surface come into engagement.

With the above and other objects in View, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a perspective view of a container having the dispensing closure applied thereto.

Figure 2 is a central cross-sectional view taken on line 2-2 in Figure l, with the stopper cap in closed position.

Figure 3 is a central cross-sectional view similar to Figure 2, with the stopper cap in open position.

Figure 4 is a central cross-sectional view similar to Figure 3, and showing a modied stopper cap.

In the illustrated embodiment of the invention,

the numeral IU generally indicates a moulded, one piece dispensing closure for bottles and the like and comprises a tubular insert member Il insertable into the neck I2 of the container I3.

The dispensing closure I0 also comprises a stopper cap I4 which is integrally connected by an elongated iiexible connecting member I5 to the tubular insert member I I. The connecting member I5 is made of a length to align the stopper cap I 4 with the insert member II when the stopper cap is brought down into closing position on the container I3.

The tubular insert member II is formed with peripheral or circular abutment collars II and I8 which grip the upper and lower faces respectively of the neck I2 of the container I3 in fluid-tight sealing relation. It Will be noted that the neck I2 is of smaller diameter than the diameter of the body member I3 which results in a peripheral or circular shoulder 20 at the junction of the neck I2 and the body I3 and against which the collar I8 abuts. In practice, the container I3 may be made of glass, metal and like rigid materials.

In the disclosure shown in Figures 2 and 3, the tubular insert member II has a disk-like partition wall 22 having a central through opening 23, the said wall 22 having a circular upwardly projecting side wall II' extending from abutment collar I 1.

The tubular insert Wall portion II has a radially outwardly extending rib 24 at its upper edge while the stopper cap I 4 has a circular cavity 25 adjoining the lateral Wall 26 thereof. In closed position, with the stopper cap I4 on the tubular insert wall portion I I", the rib 24 is seated in the cavity 25 in fluid-tight sealing engagement.

The stopper cap I4 has an integral tapering plug 27 centrally thereof and of a length to seat in the opening 23 in the disk-like partition Wall 22 of the tubular insert member I I and augments the sealing elect of the stopper cap I4 in closed position. The stopper cap I4 is provided with a handle 28.

It will thus be noted that the dispensing closure I D provides dual sealing elects when in closed position on the container I3, both of the sealing eil'ects acting simultaneously.

Figure 4 is a central cross-sectional view, similar to Figure 3, and showing a modied dual sealing effect dispensing closure 30 moulded in one piece and comprising a tubular insert member 3I and astopper cap 32.

The tubular insert 3I is the same as the tubular insert member II, but without any partition wall.

The stopper cap 32 has a tapering plug 33 of a size to contact the entire inner wall 34 of the tubular insert 3| in fluid-tight sealing relation.

Thus it will be seen that I have provided a dispensing closure or dispensing cap having a dual sealing effect in connection with a tubular insert within a Container.

The insert within the container is also provided with a dual sealing effect as at collars I1 and I8, collar I8 being squeezed in order to be tted within the neck I2 of body or container I3. The resiliency of insert II brings about engagement of collar I8 with shoulder 20.

It is to be noted that the insert and the dispensing closure or cap is made of a single piece of flexible plastic material such as polyethylene or other plastic and that insert and closure may be easily and quickly applied to the neck of a container, such as a bottle, and when so applied is ornamental in appearance. The dispensing cap has an opening or orifice of predetermined size and a plug arrangement for closing or opening the orifice, and is so arranged that a slight pressure applied to the handle 28 on the cap I4 will pry the cap supported on hinge I5 from rib 24 and permit the material in the container to be dispensed therefrom. Rib 24 and the cavity 25 serve as the latching means for cap I4.

I wish it understood that minor changes and variations in the integration, location, material and size of parts may all be resorted to without departing from the spirit of the invention and the scope of the appended claims.

I claim:

l. A dispensing closure for a container having a neck of small diameter and a body of larger diameter and a shoulder inwardly of and at the junction of said neck and body, said dispensing closure comprising an integral and tubular member insertable in and fitting said neck and eX- tending beyond the edge thereof and having upper and lower abutment shoulders adapted for engagement with the upper and lower faces of said neck, and a hollow stopper cap yieldably and integrally connected with said tubular insert member and adapted to be brought in sealing engagement with the upper part of said insert member, said insert member having an opening and said stopper cap having a tapering plug seating in said opening under pressure for augmenting the sealing eect of said stopper cap.

2. A dispensing closure for a container having a neck of small diameter and a body of larger diameter and a shoulder inwardly of and at the junction of said neck and body, said dispensing closure comprising an integral and tubular member insertable in and fitting said neck and extending beyond the edge thereof and having upper 0 Number 4 and lower abutment shoulders adapted for engagement with the upper and lower faces of said neck, and a hollow stopper cap yieldably and integrally connected with said tubular insert member and adapted to be brought in sealing engagement with the upper part of said insert member, said insert member having a partition having an opening and said stopper cap having a tapering plug adapted to be urged in said opening under pressure for augmenting the sealing effect of said stopper cap in closed position.
