If you place the first straw and straw while the cap is opened, drink may flow out from the straw due to
pressure difference caused by the temperature difference between the inside and outside of the cup.
In this case, as shown in Figure B, hang the air vent on the protruding part of the adapter side to open
the air valve to release pressure and prevent drink from flowing out from the straw.
※If you overturn and carry the cup in the state shown in Figure B, drink may spill out. Before handing
over the cup to children, be sure to restore the air vent to the normal state (as shown in Figure A).
※As shown in the Figure C on the right, press the air vent with fingers to make it deform and
temporarily release pressure.
If you boil the cup using little
hot water or a small pot, the
product may closely contact
with the pot, thus causing
deformation.

cap. Otherwise, scald may occur due to leakage or overflow. In addition, the
cup body may become hot. Be careful when using. Keep the cup out of the
reach of children.
● Do not give the mug to the baby when the liquid temperature is high. The hot
liquid may leak out and injure the baby.
● Do not fill hot drink in the cup with air valve closed or let the cup subject to violent vibration or impact
Otherwise, drink may overflow from the cup mouth due to rise of internal pressure caused by air
expansion in the cup, thus causing scald.
● Be sure to use the parts sold separately for the Lakumug series.

leakage. It is recommended to replace the parts in time.
Lakumug is leak-proof design, but the drink inside may still leak out
depending on the storage conditions or position. If you are worried
about getting your bag wet when carrying it out, please put it in a
sealed bag just in case.
●
●
Leakage may occur when the cup is placed horizontally or upside
down.
Please don’t keep the cap open when carry the cup with a bag.
When the cup contains drink with the temperature higher than human
body temperature, pressure in the cup will rise, which may cause
leakage. Fill in the cup after the drink cools down.
●
● When the drink cooled in a refrigerator is filled in the cup, the drink may leak due to rise of pressure
in the cup caused by temperature difference inside and outside the cup.
● When the cup contains cold drink, condensation occurs on the surface of the cup, thus producing
water drops.
● Never use the mug to carry formula milk when outing, otherwise the milk may go bad.

Cautions when microwave heating
Large cup 300ml
When using
the first straw,
do not use the
300ml large
cup.
※The age indicated is the estimated start time
of training. The actual start time should be
determined according to the growth situations of
children. In addition, adults should help children
before they can drink using the cup unaided.
Lakumug first straw is a straw type mug that can
be used for training of drinking.
● To assit the child’ s smooth
transition from nipples to
straws, the drinking
spout is designed
with an enlarged base
transitioning to the
straw shape, so baby
can easily hold it in their
mouth like a nipple.
● When baby holds the
straw in their mouth,
the base of the straw is
pressed and water of
an appropriate
amount flows out
from the tip of the
straw. As baby
drinks they are
learning how to use
the straw by holding
it in their mouths,
pushing and sucking.
● The slit can be opened
to let the water flow out
only when children
keep the drinking spout
in their mouths.
Therefore, you can
train drinking using the
cup without worrying
about spilling.
● When children drink
using the first cup,
adults should help
them because children
cannot control the tilt
angle. A tilt check
window where the tilt
angle can be easily
viewed is adopted.
※For the target tilt ange,
see "First cup"
(Pages 11 to 12).
● The product adopts a unique
valve structure and is leak-
proof. When the cap is
opened, you can prevent
the straw from leaking
through the manual air
valve.
● The drinking spout adopts
the tip shape that makes
it easy for children to hold
in mouth.
● The drinking spout is
made of a soft material
and can protect the
mouths of children.
(Biting hard may
cause crack.)
