between each adjacent pair of protrusions. For example, in an embodiment which
includes
four protrusions 136, a first notch 140 may be located between the first
protrusion and the
second protrusion, a second notch may be located between the second protrusion
and the
third protrusion, a third notch may be located between the third protrusion
and the fourth
protrusion, and a fourth notch may be located between the fourth protrusion
and the first
protrusion.
[0051] The notch 140 may facilitate the insertion of the valve. The notch
140 may allow
the retention feature 134 to deflect so that the valve may be inserted. In
addition, the notch
may facilitate the removal of the container from a molding machine.
[0052) Referring to Fig. 5, the valve 132 may be made of a flexible
material. In one
embodiment, the valve may be made of silicone. In other embodiments, the valve
may be
made of a thermoplastic elastomer. The valve 132 may include an opening 142
which allows
the contents to be dispensed. In one embodiment, the opening 142 may be a slit
144. In a
second embodiment, the opening May be two slits. The first slit may cross the
second slit at
an angle. In one embodiment, the angle may be 90,degrees. In other
embodiments, the angle
may be between 1 degree and 89 degrees.
[0053] The valve 132 may be attached to the container. Referring to Fig. 5,
in one
embodiment, the valve 132 may be attached to the end portion 104. The valve
132 may be
attached using the retention feature 134. In other embodiments, the valve may
be attached
using an adhesive, fusion (such as sonic welding) or deformation of the
container (such as, by
crimping with or without heating). In another embodiment, the valve 132 may be
used with a
retaining ring as discussed below.
[0054] Referring to Figs. 6 and 7, a second embodiment of a valve is shown.
The valve
146 may include an opening 148. The opening 148 may be any one of the openings
Date Recue/Date Received 2022-06-28

discussed above for valve 132. Referring to Fig. 7, the valve 146 may include
an outer
portion 150, an intermediate portion 152, and an inner portion 154. When
pressure is applied
to the exterior of the container, the interior pressure of the container will
cause the
intermediate portion 152 and the inner portion 154 to deflect outwards as
shown in Fig. 10
and allow the contents to exit the opening 148. When the pressure is removed,
the
intermediate portion 152 and the inner portion 154 return to the positions
shown in Fig. 9.
The valve 146 may be attached using the retention feature 134. In other
embodiments, the
valve may be attached using an adhesive, fusion (such as sonic welding) or
deformation of
the container (such as, by crimping with or without heating). In another
embodiment, the
valve 146 may be used with a retaining ring 158 as discussed below.
[0055] The container 100 may include a valve retaining ring. Referring to
Figs. 8 and 9,
the retaining ring 158 may engage the retention feature 134. The valve 146 may
be located
between the retaining ring 158 and the end portion 104. In one embodiment, the
retaining
ring 158 is a part which is separate from the valve 146. The retaining ring
158 may be made
of a material which is harder than the valve 146. For example, the valve may
be made of
silicone and the retaining ring may be made of polypropylene. In other
embodiments, the
valve may be made of a thermoplastic elastomer. In other embodiments, the ring
may be
made of nylon, or polyamide. In one embodiment, the valve 146 may be inserted
into the
container and then the retaining ring 158 may be inserted into the container.
The retaining
ring 158 may then engage the retention feature 134. In another embodiment, the
valve may
be molded onto the retaining ring as shown in Figs. 11 and 12.
[0056] Referring to Figs. 11 and 12, a third embodiment of a valve is
shown. The valve
160 may be molded onto a retaining ring 162. The retaining ring 162 may be
made of a
material which is harder than the valve 160. For example, the valve may be
made of silicone
and the retaining ring may be made of polypropylene. In other embodiments, the
valve may
be made of a thermoplastic elastomer. In other embodiments, the ring may be
made of nylon,
or polyamide. Referring to Fig. 13, the valve 160 may be attached using the
retention feature
134. In one embodiment, the valve 160 and retaining ring 162 may be inserted
into the
container. The retaining ring 162 may then engage the retention feature 134.
Referring to
Fig. 12, the valve 160 may include an opening 164. The opening 164 may be any
one of the
openings discussed above for valve 132. The valve 160 may include an outer
portion 166, an
intermediate portion 168, and an inner portion 170. When pressure is applied
to the exterior
of the container, the interior pressure of the container will cause the
intermediate portion 168
Date Recue/Date Received 2022-06-28

10
and the inner portion 170 to deflect outwards and allow the product to exit
the opening 164.
When the pressure is removed, the intermediate portion 168 and the inner
portion 170 return
to the positions shown in Fig. 12.
[0057] Referring to Fig. 12, the retaining ring 162 may be larger than
valve 160. For
example, the outer perimeter 172 of the retaining ring 162 may be greater than
the outer
perimeter 174 of the valve 160. Thus, in situations which require a large
outer perimeter 172
for the retaining ring 162, the size of the outer perimeter 172 can be
increased but the size of
the valve 160 can remain the same. Therefore, the manufacturer can increase or
decrease the
outer perimeter 172 of the retaining ring to fit in several different sizes
and types of
containers without having to change the size of the valve 160. In addition,
the manufacturer
could also increase or decrease the thickness 176 of the retaining ring 162 in
order to fit in
several different sizes and types of containers without having to change the
size of the valve
160.
[0058] The outer perimeter 172 of the outer portion 166 of the valve may be
increased or
decreased in order to fit several different sizes and types of containers
without having to
change the size of the moving portions of the valve 160. In one embodiment,
the moving
portions of the valve 160 are the intermediate portion 168 and the inner
portion 170. For
example, referring to Fig. 13, the outer perimeter 174 of the outer portion
166 has been
decreased as compared to Fig. 12 without changing the size of the intermediate
portion 168
and the inner portion 170.
[0059] In another embodiment, the size of the moving parts of the valve can
be increased
or decreased. For example, the size of the intermediate portion 168 and the
inner portion 170
of the valve 160 may need to increase in order to accommodate a more viscous
fluid. In
addition, the size of the inner opening 178 of the retaining ring 162 can be
increased or
decreased to accommodate the increase or decrease of the intermediate portion
168 and the
inner portion 170 of the valve, but the outer periphery 172 of the retaining
ring 162 can
remain the same. Therefore, if the manufacturer decides to change the
viscosity of the fluid
in the container, the manufacturer can increase or decrease the size of
intermediate portion
168 and inner portion 170 of the valve, but the manufacturer can use the same
container since
the outer periphery 172 of the retaining ring 162 remains the same. In some
situations the
size of the outer portion 166 of the valve may change in size.
[0060] After the valve is assembled to the upper end portion 104, the
container 100 is
filled with a product. The product may be a liquid beverage enhancer. In other
Date Recue/Date Received 2022-06-28

11
embodiments, the product may be sweeteners or nutraceuticals. The product may
have a
viscosity in the first range of about 1 to about 250 centipoise at room
temperature, a second
range of about 1 to about 90 centipoise at room temperature, and a third range
of about 1 to
about 50 centipoise at room temperature,
[0061] After the container is filled with a product, the lower end portion
114 is then
closed. Referring to Figs. 14 and 15, in one embodiment, the lower end portion
114 may be
closed by using a heat seal 182. The heat seal 182 may seal one portion of the
side wall 110
against another portion of the side wall 110. The heat seal 182 may be sealed
and trimmed to
have various shapes. For example, the heat seal may be trimmed to be straight,
wavy, with
an opening for hanging, a trademarked shape, trademarked opening, a
decoration, or an
opening for a lanyard. In other embodiments, the lower end portion 114 may be
closed with
a plug or cap which may be attached to the end portion 114 with an adhesive,
fusion (such as
sonic welding) or deformation of the container (such as, by crimping with or
without
heating).
[0062] In one embodiment, the container may have product information.
Referring to
Figs. 14 and 15, in one embodiment, the product information may be a label
184. The label
184 may be applied with an adhesive. In other embodiments, the label may be
applied with
shrink wrap.
[0063] In other embodiments, the product information may be placed on the
container
using other techniques. For example, the product information may be printed
onto the
container. In another example, the product information may be embossed onto
the container.
In a third example, the product information may be applied by in-mold
labeling.
[0064] In one embodiment, the container may include a tamper evident
feature. In one
example, the tamper evident feature may be a band 186. The band 186 may be
applied over a
portion of the body and a portion of the cap. If a person breaks the band to
open the cap, then
a subsequent person would know that the container was previously opened. In
one
embodiment, the band may be applied by heat shrinking. In other embodiments,
the band
may be applied with an adhesive.
[0065] In another embodiment, the label may extend over a portion of the
cap and the
label may provide a tamper evident feature. Thus, the band may not be needed.
