Claims
I claim:
1. A pour spout adapter fitting into a bottle opening and
comprising a hollow flexible cylindrical body having a lower
portion the diameter of which is substantially smaller than that of
the inner surface of the bottle opening and a top portion
comprising a part adapted to engage said inner surface close to the
top thereof and a flange constituting an extension of said part and
adapted to extend over the top of the bottle opening, a ring
mounted in said recess and extending above said flange, a plurality
of spaced annular flexible ribs carried upon the outer surface of
the lower portion of said body, each of said ribs having an outer
diameter which before insertion into the bottle opening is greater
than that of the bottle opening and having an upper surface
extending transversely to the central axis of said cylindrical body
and a lower surface extending toward said upper surface and forming
an acute angle therewith, a solid pin located centrally
substantially within said lower portion of the cylindrical body,
and four plates, each of said plates having an edge connected to
the inner surface of said lower portion and an opposed edge
connected to said pin, each plate extending at right angles to the
adjacent plates.
Description
This invention relates to pour spout adapters and is particularly
concerned with spout adapters fitting into bottle openings.
It is a matter of general knowledge that the dispensing of
nonalcoholic as well as alcoholic beverages, such as whisky and
wines, particularly in bars and restaurants, presents numerous
problems. As soon as the cork is removed, the pouring must take
place quickly and yet precisely without spilling the beverage or
filling the glasses inadequately. This is sometimes difficult for a
bartender or a waiter operating under a strain. Another problem
results from the fact that half-filled bottles often remain
standing for days on bars and shelves where they are easily
accessible to outsiders so that it is possible, for example, to
remove the contents of a bottle of expensive wine or liquor and to
fill the same bottle with a different, cheaper beverage.
An object of the present invention is the provision of a pour spout
adapter fitting into bottle openings which will facilitate a
uniform adequate outflow of the contents of a bottle but which will
prevent quick excessive outpour or refill.
Other objects of the present invention will become apparent in the
course of the following specification.
In the accomplishment of the objectives of the present invention it
was found desirable to provide a pour spout adapter having a hollow
cylindrical body provided with resilient circular ribs adapted to
engage the inner walls of the bottle opening. The top of the
cylindrical body is dimensioned to fit into the top of the average
bottle opening and may have a flange extending over a part of the
top edge of the bottle opening. The cylindrical body is divided
into a plurality of passages for the outflow of liquid and the
return flow of air. These passages may be formed by ribs or plates
extending through most of the interior of the cylindrical body or
only a small portion thereof. The passage for the inflow of air may
be connected with an elongated tube extending into the interior of
the bottle .
The invention will appear more clearly from the following detailed
description when taken in connection with the accompanying drawing,
showing, by way of example only, preferred embodiments of the
inventive idea.
In the drawing:
FIG. 1 is a section through a bottle opening containing the spout
adapter of the present invention;
FIG. 2 is a top view of the portion of the bottle shown in FIG.
1;
FIG. 3 is a side view of a somewhat differently constructed spout
adapter, a portion thereof being shown in section;
FIG. 4 is a top view of the spout adapter shown in FIG. 3.
FIGS. 1 and 2 show a bottle 10 provided with the usual neck 11. The
spout adapter 12 constituting the subject of the present invention
fits snugly into the opening of the bottle. The spout adapter 12
may be made of any suitable material but preferably consists of a
plastic material having a certain resiliency; it includes a hollow
cylindrical body 13 having outer flexible ribs 14. As shown in FIG.
1, the ribs 14 are bent when the spout adapter 12 is inserted into
the bottle neck 11 a they firmly engage the inner walls of the
bottle opening. The top portion 15 of the spout adapter has an
outer cylindrical surface engaging the inner cylindrical surface of
the bottle opening close to the top thereof. The portion 15
terminates in a flange 16 extending over a part of the top surface
of the bottle opening. The portion 15 has an inner recess carrying
a ring 17 which may be of different color and composition that the
spout adapter. The ring 17 extends slightly above the flange 16 and
is used to facilitate the pouring of the liquid out of the
bottle.
In accordance with the present invention the interior of the spout
adapter is divided into several compartments 18. In the
construction shown in FIGS. 1 and 2 these compartments are formed
by four elongated plates 19. Each plate 19 has an edge fixed by any
suitable means, such as heat sealing, to an inner surface of the
spout adapter, while its other edge is fixed to a centrally located
pin 20. Uniform compartments are produced by arranging the plates
19 in pairs extending at right angles to each other.
It is apparent that when liquid is poured out of the bottle, the
ring 17 may be used as an effective support. Liquid will flow
uniformly at a moderate rate out of some of the compartments 18
while at least one compartment 18 will provide return flow of air
into the bottle. The spout adapter constitutes a fixture making it
difficult or at least inconvenient to quickly transfer the contents
of one bottle into another bottle.
The spout adapter 21 shown in FIGS. 3 and 4 also includes a hollow
cylindrical body 22 having outer flexible ribs 23 similar in shape
to ribs 14. However, in this construction, the interior of the body
22 has no compartments but is closed by a plate 23 firmly connected
to the outer flange 24 of the body 22. The plate 23 has a large
opening 25 communicating with the interior of the body 22 and used
for the outpouring of the liquid. The plate 23 also has a hole
carrying the top of a tube 26. The tube 26 extends through the
cylindrical body 22 into the interior of the bottle.
This construction can be also used effectively for pouring contents
of a bottle through the opening 25, while air will flow into the
bottle through the tube 26.
