CREAM DISPENSER WITH PLEATED WALLS AND LIP TYPE OPENING
Abstract
A cream dispenser in the form of a container of flexible
material such as plastic having generally flexible top and bottom
walls and pleated, collapsible sidewalls, an opening in one
sidewall in the form of an elongated slit, flexible lips along the
opposite sides of the slit, the lips normally closing the slit but
being deflectable outwardly to permit discharge of the contents
upon pressure being applied to container to collapse the same and
said lips being deflectable inwardly upon insertion of a nozzle to
recharge the dispenser and a removable closure for the opening.

Claims
Having described my invention what I claim as new is:
1. A cream dispenser comprising:
a. a container having substantially flat end walls and pleated
sidewalls rendering the container expansible and collapsible;
b. an outwardly extending thickened portion forming a spout
integral with a pleated sidewall, said thickened portion being
rectangular in shape and having an elongated opening
therethrough;
c. a pair of flexible lips extending inwardly from opposite
sidewalls of said opening and contacting each other along a line
between said sidewalls and closing said opening, said flexible lips
being deflectable outwardly to allow discharge of the contents of
the container therebetween and being deflectable inwardly to permit
insertion of a spout to fill the container;
d. a pair of parallel grooves in opposite sides of the thickened
portion forming the spout; and
e. a cover having opposed inturned flanges slidably positioned in
said grooves to removably attach said cover to said spout.
Description
This invention relates to dispensers and more particularly to
dispensers for cream products such as soap, shaving cream, tooth
paste and the like and to such dispensers which when empty may be
readily refilled by the user.
It is an object to provide a dispenser of the character stated
which is compact and neat in appearance.
It is another object to provide a dispenser which may be
economically manufactured.
A still further object is to provide such a dispenser which has a
self closing discharge opening which will automatically open when
pressure is applied to the container portion thereof to permit
discharge of the contents but will, of itself, close when pressure
is released.
An additional object is to provide a dispenser which may be readily
recharged when empty and capable of repeated discharge and
charge.
Additional objects and advantages will become apparent as this
description proceeds and reference is had to the accompanying
drawing forming a part of this specification.
In said drawing:
FIG. 1 is a perspective view of a dispenser according to my
invention;
FIG. 2 is a fragmentary longitudinal sectional view of the
discharge end of the dispenser showing details of the valve in the
discharge opening and the outer cap;
FIG. 3 is a longitudinal sectional view substantially along the
line 3-3 of FIG. 1 as it appears when hand pressure is applied
thereto;
FIG. 4 is a fragmentary sectional view of the discharge end of the
dispenser with a recharge nozzle inserted therein;
FIG. 5 is a view similar to FIG. 4 taken at right angles thereto
and substantially on line 5-5 of FIG. 4; and
FIG. 6 is a fragmentary perspective view with the outer cap removed
from the discharge opening.
Referring now to the drawing in more detail the device comprises a
container portion generally indicated 10 and a spout portion
11.
The container portion 10 is composed of relatively flat top and
bottom panels 12 and 13 respectively, connected on all sides with
accordion pleated sidewalls 14. The container is made of relatively
flexible material such as plastic. Although not necessary, the top
and bottom panels may be made slightly more rigid than the pleated
sidewalls to help retain the shape of the container and to this end
ribs 15, which may be ornamentally arranged, can be used on the top
and bottom panels as shown in FIG. 1.
The spout portion 11 is formed as a thickened portion 16 formed
integral in one of the pleated sidewalls and is provided with an
opening in the form of an elongated slit 17. Positioned within this
slit and extending inwardly from opposite walls thereof are a pair
of flexible lips 18 which normally meet at the center of the slit
and function to close the same as shown in FIG. 2. These lips
however may be deflected outwardly if the container is pressed and
the contents may be expelled. They will however return to their
closed position when the pressure on the container is released.
As above briefly stated and as shown in FIGS. 4 and 5 the dispenser
may be refilled when empty. This is accomplished by the use of a
stock container 19 having a spout 20. The spout is inserted in the
slit and in this case the lips 18 are deflected inwardly and the
contents from the stock container expelled through the spout and
into the container 10 of the dispenser.
A cap 21 may be utilized to cover the slit 17. This cap is
generally channel shaped with inturned side flanges 22 which are
slidably received in grooves 23 in the member 16. The cap may thus
be removed or replaced by a simple sidewise sliding motion.
