'2 Claims.
The invention relates to improvements in closures for containers as described in the present specification and shown in the accompanying drawing that forms part of the same.
The invention particularly concerns a container for semi-liquid substances such as shaving cream, and has for its object to provide an efficient and reliable closure structure incorporating a dispensing orifice controlled by a floating or loose sealing member.
The closure preferably has a threaded connection with the container, which may be a collapsible tube, and the orifice is encircled by a seat engaged by the sealing member in the closed position of the closure. The sealing member is shouldered against the container and is supplied with passages leading to the seat.
The salient feature of this construction is that by partially turning the closure in a screw-off direction, the compression of the tube causes the contents to fiow into the passages and to forcibly unseat the sealing member so as to discharge through the orifice. The tightening of the closure seals off the outlet opening and the ejected material can be readily removed.
According to this invention it is not necessary to remove the cap from the tube in order to discharge the contents. Furthermore, it is simple to operate and easy to regulate in order to obtain the desired quantity of material each time the tube is used.
Referring to the accompanying drawing, Figure 1 is a perspective view of a container embodying the present invention.
Figure 2 is an axial sectional view of the closure and neck portion of the container on an enlarged scale.
Figure 3 is a perspective view of the sealing member.
Figure 4 is a similar section to Figure 2 but showing a slightly modified form of sealing member.
Figure 5 is a side elevation of the variant sealing member detached from the container of which only the neck portion is shown.
Like numerals of reference indicate corresponding parts in each figure of the drawing.
The collapsible tube 6 is of the conventional construction, having an externally threaded neck I terminating in an abrupt face with a central opening.
The closure is in the form of a screw cap 8 having the rear portion of its bore internally threaded as at 9 to threadedly engage the neck 1.
The threaded bore leads to a seat I in the form of a frustum of a cone, which terminates in the discharge orifice l I.
The sealing member is substantially in the shape of a frustum of a cone and has a face I2 engageable with the seat 10 so as to close the orifice. In the preferred form shown in Figures 2 and 3, a reduced extension is provided as at l3 for the purpose of constituting a guide.
The rear face l2 of the sealing member abuts the end face of the neck I. The passages are composed of the peripheral flutes l4 communicating with the interior of the tube and terminating at the face l2. Any number of flutes may be supplied.
In the modification shown in Figures 4 and 5, the extension I3 is dispensed with, and projections as at l are furnished to fit into notches as at It in order to preclude the sealing member from turning. Additionally, the fiutes are replaced by ducts ll consisting of small holes communicating with the bore of the neck. The periphery of the sealing member may be threaded to screw into the cap with the neck.
In operation, when the cap is tightened, the seat ill bears against the face l2 of the sealing member and thus closes the orifice. By giving the cap a partial turn from its closed position and compressing the tube, the material is urged through the passages and unseats the sealing member. This provides a space I 8 through which the material may fiow to the orifice. It is important that the passages communicate with the seat l5), otherwise the sealing member will stick in its closed position when the cap is loosened and block the orifice. The fluid pressure releases the scaling member in the construction herein disclosed.
What I claim is:
1. A closure for a collapsible tube or other contain-er having a dispensing orifice encompassed by a threaded neck, said closure comprising a cap threadedly engaged with the neck and having a bore forming a seat encircling an orifice, and a sealing member loosely mounted in the bore thereof having a face engageable with said seat to seal off the orifice, said sealing member having discharge passages terminating at said face and controlled by the seat of the cap.
2. A closure for a collapsible tube or other container having a dispensing orifice encompassed by a threaded neck, said closure comprising a cap threadedly engaged with the neck and having a bore forming a seat encircling an: orifice, and a sealing member fioatingly lodged in the bore thereof in abutment with said neck, said sealing member having a face engageable with said seat to seal ofi the orifice encompassed thereby and having discharge passages terminating at said face and controlled by the seat of the cap.
3. A closure for a collapsible tube or other container having a dispensing orifice encompassed by a threaded neck terminating in an end face, said closure comprising a cap threadedly engaged with the neck and having a bore forming a seat encircling an orifice, and a sealing member fioatingly lodged in the bore thereof and shouldered against the end face of said neck, said sealing member having a face engageable with said seat to seal off the orifice encompassed thereby and having discharge passages terminating at said face and controlled by the seat of the cap.
4. A structure in accordance with claim 2, in which the discharge passages of the sealing member consist of peripheral flutes.
5. A structure-in accordance with claim 2, in which the discharge passages of the sealing member consist of ducts communicating with the dispensing orifice of the neck.
6. A structure in accordance with claim 1', in
which the sealing member is provided with means to preclude its turning with the cap.
7. A closure for a collapsible tube or other 7 container having a dispensing orifice encomingly lodged in the bore, said sealing member be-' ing substantially shaped in the form of a frustum i of a cone of which the conical face is engageable with said seat, said sealing member having a rear end face shouldered against the afore-i said end face of the neck and having discharge" passages communicating with the dispensing orifice of the neck and terminating at said conical face.
