Abstract

A container having a neck arrangement including a circular spout (30) and a guiding neck portion with a U-shaped ledge (60). During a pouring operation the ledge directs liquid from the container over the front edge of the spout (78) and permits air to enter the container through the rear portion of the spout (63) and an air passageway (58) connecting the rear of the spout with the inside of the container.

Description

VENTED PLASTIC BOTTLE
TECHNICAL FIELD
This invention relates generally to containers for dispensing liquid
and more specifically to a container having a novel pouring spout
arrangement by which the space above the liquid is vented to permit air
to be drawn into the space during a pouring operation to prevent the
glugging or gulping phenomenon associated with many conventional
bottles.
This invention is particularly applicable to blow-molded plastic jugs
or bottles used for dispensing a variety of different types of liquids, some
of which may be toxic or flammable. As the bottle is tipped forwardly, the
mouth or neck portion will normally be lowered below the liquid level in
the bottle, trapping the air in the bottle above the liquid. If no vent is
provided to admit air into this region, the flow of liquid out of the bottle
will alternate with the flow of air into the jug, causing a glugging or gulping
action. Because of the glugging action the poured stream is difficult to
control, so that the user may make a mess with the liquid. When that
liquid is toxic or flammable this can create a dangerous situation. BACKGROUND ART
In the past, various attempts have been made to provide containers
with a vent feature to overcome this glugging problem. Typical prior
proposals are illustrated in U.S. Patents 3,251,514, 4,412,633, 4,804,119,
and in PCT International Publication No. WO-86/02334, and those designs
are improvements over the conventional bottles.
In larger blow molded plastic bottles, for example 35 pound or 2
gallon jugs, it is desirable that the neck area be both level and strong
because the automatic filling and capping machines which are used to fill
the jugs require a dimensionally consistent and strong neck to work
efficiently. U.S. Patent 5,144,028, assigned to the assignee of this
application precedes a bridge top construction to maintain the level
position. Applicant has discovered that it is very desirable to provide a
bottle of the type illustrated in Patent 5,144,028 with a spout arrangement
which alleviates the glugging action during a pouring operation.
DISCLOSURE OF THE INVENTION
A primary object of the invention is to provide a container with a
novel neck construction which eliminates glugging action as liquid is
poured from the container. Still another object of this invention resides in the provision of a
container having novel neck arrangement, including a neck and handle
design which form a bridge between the front and rear walls of the
container and a guiding neck portion which deflects the liquid toward the
forward edge of the outlet spout of the bottle as the liquid is poured from
the bottle.
Still another object of the invention resides in the provision of a container as described above wherein the outlet spout is displaced axially
rearwardly of the axis of the guiding neck portion, and the rearward
position of the spout communicates with a hollow handle to permit air to
freely enter into the bottle during a pouring operation.
These and other objects of the invention will become apparent from
reading the following detailed description of the invention in which reference is made to the accompanying drawings wherein like numerals indicate like elements.
BRIEF DESCRIPTION OF DRAWINGS
Figure 1 is a generally perspective view of the novel blown plastic
bottle of the invention.
Figure 2 is a top plan view of the bottle. Figure 3 is a side elevational view of the bottle taken along line 3-3
of Figure 2.
Figure 4 is a fragmentary sectional view taken along line 4-4 of
Figure 2.
Figure 5 is a fragmentary sectional view taken generally along line
5-5 of Fig. 4; and
Figure 6 is a similar view to Figure 4, but illustrating the bottle in
its tilted position in which liquid is poured from the bottle.
BEST MODE FOR CARRYING OUT THE INVENTION
Referring now to the drawings, the one piece blow molded plastic
container or bottle 10 includes bottom wall 12, vertical front wall 14, rear
wall 16, and side walls 18 and 20 which define a liquid containing chamber
22 of generally rectangular cross section and a top wall 24 joining walls 14,
16, 18, and 20 to close chamber 22.
Integrally formed on top of wall 24 adjacent front wall 14 is a neck
platform 30 having a forward wall 32 including a vertical section 34 which
extends along and coextensively upwardly from wall 14 and blends with a
rearwardly tapered section 36 which terminates in a top wall portion 38 on
which is formed a circular threaded outlet spout 40 normally closed by a cap (not shown). Platform 30 includes a pair of side walls 42 and 44 which
extend rearwardly from front wall 14 generally parallel to side walls 20 and
22 to a point about the diametral line of spout 40 and then around the
spout to a junction area 46 where they join with a narrow hollow handle
50 which is connected at its rearward end 52 to wall 16.
Platform 30 also includes a guiding neck portion 54 connected
between and blending with top wall 24 and side walls 42 and 44. Side
walls 42 and 44 define a transitional chamber 56 which extends from
tapered front wall 36 to area 46 where it connects to the forward end of
an air passageway 58 defined by hollow handle 50, the rearward end of
passageway 58 extending through top wall 24 and communicating with chamber 22.
As seen best in Figures 2, 4, and 5, guiding portion 54 forms a
horizontal generally U-shaped ledge 60 having a rear portion 62 extending
forwardly of juncture 46 and the rear edge 63 on a diametral line of spout
40 which is parallel to side walls 20 and 22. Ledge 60 also includes side
sections 66 and 68 which blend with rear section 62. The inner edge of
section 62 runs generally parallel to front wall 14 and the inner edges of
side sections 66 and 68 run generally parallel to walls 20 and 22. Together
those inner edges form a generally U-shaped pouring edge 70 which diverges outwardly at 72 and 74 to intersect with side walls 42 and 44
adjacent the front wall 36. As shown in Figure 2, those inner edges are
spaced inwardly from the rear edge 63 and from the side edges 64 and 65
in a diametral line of spout 40 which is parallel to front wall 14 so as to
deflect and guide the liquid from chamber 22 into the front portion of
chamber 56 and over the front edge 78 of spout 40 away from the rear
edge 63 and the side edges 64 and 65 on a diametral line of spout 40
which is parallel to front wall 14 so as to deflect and guide the liquid from
chamber 22 into the front portion of chamber 56 and over the front edge
78 of spout 40 away from the rear edge 63 and the side edges 64 and 65
of the spout as shown in Figure 6. This permits air indicated by arrow 80
to enter the spout along side edges 64 and 65 and rear edge 63 into
passageway 58 and into chamber 22 preventing the unwanted glugging
action.
The U-shaped edge 70 diverts the liquid stream away from the sides
and rear of the spout, producing a smaller area but higher velocity of
liquid flow over front edge 78 and eliminating spillover over the side edges
64 and 65. The edge 70, as it blends with the forward portions of walls 42 and
44 and tapered wall 36, forms a constrictive, directional neck area 82
which has a cross-sectional area greater than the cross-sectional area of the
outlet formed by spout 40. Also, as is evident in Figure 2, the axis of
spout 40 is displaced rearwardly toward the handle from the axis of the
opening defined by edge 70 and this ensures that the liquid is properly
deflected, as shown in Figure 6, to prevent any glugging action.
The construction of the platform 30 and handle 50 not only provides
the desired no-glugging function, but also retains the strength referred to
in Patent 5,114,028, necessary to maintain the spout 40 in a level position
and to resist downward deflection of the spout during the filling operation.
The invention may be embodied in other specific forms without
departing from the spirit or essential characteristics thereof. The present
embodiment is therefore to be considered in all respects as illustrative and
not restrictive, the scope of the invention being indicated by the appended
claims rather than by the foregoing description, and all changes which
come within the meaning and range of equivalency of the claims are
therefore intended to be embraced therein.
