Description
TUBULAR GLASS BOTTLE NECK
Technical Field
The present invention relates to the field of tubular glass bottle necks, more
specifically to necks of glass bottles that are manufactured automatically and provided with
an annular collar in the form of a protruding annular glass flange around said neck molded
simultaneously with the rest of the tubular bottle neck and used as a gripping point for
removing the bottle from inside the mold after the manufacture thereof.
The proposed glass bottle neck is suitable for the automatic production of bottles by
means of a molding process for molding part of the neck of the bottle and subsequent
blowing of the rest of the bottle, provided with an annular collar for removing the bottle from
the mold, wherein the neck consists of a collar segment provided with an annular collar, a
transition segment provided with an annular outer recess, and a wide segment with an outer
wall face flush with the outer collar face and with an internal conduit having a diameter that is
larger than the internal conduit of the collar segment, with the annular outer recess being
recessed with respect to the outer collar face and with respect to the outer wall face of the
wide segment.
State of the Art
Tubular glass bottle necks are known in the state of the art. In those bottles produced
automatically by means of glassblowing inside a mold, it is also common to include an
annular collar around the tubular neck, in a position close to the mouth of the neck, with the
mentioned collar and mouth of the neck being produced in a prior molding stop, which allows
a very precise dimensional control of the diameter of the mouth of the tubular neck and the
use of said collar for gripping the bottle and removing it from the mold automatically after the
manufacture thereof. Machines for automatically manufacturing glass bottles with industrial
production volumes used today are all based on this manufacturing principle, described for
the first time in patent US774690 from 1904.
However said collar, required for the industrial manufacture of bottles, produces a
projection on the outside of the tubular neck, which, in the case of beverage bottles, makes it
difficult to place a capsule and remove it, and it does not help with the shearing off of said
capsule, and it could furthermore be an impediment for handling the bottle, or for placing
labels on said neck.
In bottles of another type, such as bottles provided with a thread, for example,
produced automatically with a process identical to the one described before, said collar
typically must necessarily be arranged farther away from the mouth than the thread, with the
thread being above the collar so as to prevent the collar from interfering with the screw cap,
preventing its access to the thread of the neck. Therefore, the conventional construction of
necks with a thread consists of, in this order starting from the mouth, the thread, the collar,
and finally the shoulders of the bottle. This construction determines that there is always a
groove between the cap and shoulders of the bottle which is defined by the distance existing
between the collar and said shoulders, preventing the cap from being able to rest on the
shoulders unless special caps that are very expensive to produce are used; it is even more
common for the collar to be completely visible, included in said groove, which affects the
aesthetic appearance of the product.
Bottles manufactured with different techniques other than molding the mouth with a
collar and subsequent blowing of the rest of the body of the bottle are known, where these
techniques allow dispensing with the collar, but production costs are much higher as they are
not industrial-scale techniques, such as artisanal techniques, semi-artisanal techniques, or
other techniques based on other principles, such as the narrowing of a tube of glass, for
example, shaping it into a bottle.
Bottles with a neck devoid of a collar are known, which make labeling tasks easier,
and furthermore include an annular groove around same suitable for serving as a guide for
shearing off a cap placed on the neck, or for serving as a drip edge, although that is not the
objective proposed in the documents describing those solutions.
Documents GB189714441A and GB189725405A are examples of documents of that
type, both documents being earlier than the invention for the automatic manufacture by
molded the mouth and subsequent blowing, so they do not correspond to bottles produced
with said technique.
Furthermore, in both cases the thickness of the glass of the neck of the bottle is
constant, except in the mentioned groove, where its thickness is reduced, constituting a
weakening whereby facilitating the breaking of the neck at that point for opening same, with
the inner diameter of the bottle being constant. This indicates that the type of glass used is a
borosilicate glass the breaking of which does not produce sharp edges or shards, with that
material being typical during production staring from a preformed glass tube which is then
heated and narrowed at its ends, forming a bottle or container, which is confirmed by the
absence of a collar, which is impossible to obtain using other industrial-scale techniques.
This technique does not allow automatic large-scale production at competitive prices
compared to the manufacture by molding and subsequent blowing, since it requires first
producing a glass tube, and then molding it, resulting in a bottle made of a brittle glass.
Therefore, in conclusion, there is no known solution which allows the automatic
manufacture of bottles by means of the techniques and machines normally found in the
sector, which use the technique of molding the mouth with a collar and then blowing the body
of the bottle, but without the drawbacks of having an annular projection in the form of a collar
around the bottle neck, which makes it difficult to label and screw caps on around same.
Brief Description of the Invention
The present invention relates to a tubular glass bottle neck, particularly a tubular neck
of glass bottles that are produced automatically.
The term bottle must be understood not to entail a limitation to a single type of
containers, but rather the present invention is extensible to any other glass container
provided with a neck and a mouth obtained by molding part of the neck and the mouth by
molding and subsequent blowing of the rest of said container, such as for example jars, jugs
and vases.
For their automatic manufacture, glass bottles require an annular projection adjacent
to the mouth of the neck of the bottle which allows a firm gripping of the bottle during the
manufacture thereof for transferring the molten glass preform from the forming mold for
forming the mouth to the blow mold and for removing the bottle from inside the blow mold
after the manufacture thereof by blowing. Said annular projection is typically achieved by
including a protruding annular collar in the form of an annular flange projecting from the outer
face of the bottle neck providing an annular collar projection which performs the described
function. Said collar is present in bottles devoid of a thread on its neck, such as bottles of
wines, sparkling wines, and other beverages, for example preferably in bottles stoppered
with a cork or plastic stopper inserted under pressure; are also known bottles provided with a
thread which also include the mentioned collar, especially in jars for food or cosmetic use.
The insertion of the stopper under pressure into the tubular neck requires enormous
precision in the manufacture thereof, especially in the part of the inner conduit closer to the
mouth, where the stopper must be fixed; as a result, the tolerances allowed in the
manufacture of that part are much stricter than those of the rest of the tubular neck. The
same occurs with the outer dimensions of the threads in screw caps.
The usual manner of obtaining said neck and achieving the desired precision consists
of molding a preform which includes that most critical area adjacent to the mouth, including
the collar and the inner conduit closer to the mouth, pressing the molten glass inside the
mold with a pressurized gas or with a piston, thereby compacting the glass and the glass
being perfectly fitted with the mold. Then, and before the glass hardens, the obtained
preform is removed and introduced in another blow mold, where the rest of the neck and the
body of the bottle are formed by means of blowing of pressurized air through the mouth
formed in the preform, which expands the preform until adapting it to the shape of the mold,
but without the parts closer to the mouth being altered, therefore the strict tolerances of that
part are complied with, whereas in the rest of the bottle the thickness will be kept within the
higher tolerances. The formed bottle is then removed from the blow mold.
In the operations for removing both the preform and the bottle from inside the molds,
the collar is essential as it allows proper gripping of the glass by the automatic production
apparatus.
The tubular glass bottle neck therefore includes:
• a tubular wall defining an inner conduit, an outer wall face, and a mouth
accessible from outside the bottle and connected in continuation to a bottle body;
• a protruding annular collar on the outer surface of the tubular wall in a position
adjacent to the mouth, with said annular collar being provided with an outer collar
face confined between two annular collar projections;
It will therefore be understood that the proposed neck will be connected in
continuation to a bottle body, for example through shoulders interposed between the bottle
body and the tubular neck, with the inside of said bottle body only being accessible through
the tubular bottle neck and mouth.
The proposed bottle neck furthermore includes the following features:
• said tubular wall defines a collar segment, a transition segment, and a wide
segment successive to and aligned with one another and with their respective
inner conduits being connected to one another,
• the collar segment includes the annular collar and the mouth, with the thickness
of the annular collar being added to the thickness of the tubular wall in at least
part of said collar segment;
• the outer wall face of the wide segment is flush with the outer collar face, and the
inner conduit thereof has a cross section having a larger size than the cross
section of the inner conduit of the collar segment; and
• the transition segment links the collar segment and the wide segment, the inner
conduit thereof comprises successive cross sections having an increasing size
connecting the inner conduits of the collar segment and the wide segment, and
outer wall face thereof has at least two successive cross sections having a
different size, connecting the outer wall faces of the collar segment and the wide
segment, defining an annular outer recess between the collar and the wide
segment.
Therefore, the outer collar face and the outer wall face are flush with one another in
their wide segment, avoiding outer projections and protrusions in the bottle neck, and they
are separated from one another by an annular outer recess in which there is provided an
annular collar projection which allows gripping the bottle for removing it from the mold during
the manufacture thereof, and producing a unique aesthetic effect, since the collar is visually
integrated in the tubular neck assembly, without projecting from same, as a result of the
increase in diameter of the wide segment until it is externally flush with the collar.
Preferably, the thickness of the tubular wall will be the same in the collar segment and
in the wide segment, and it can also be the same in at least the annular outer recess and/or
in the entire transition segment.
Having the collar and outer face flush with another allows facilitating, for example in
beverage bottles, the operations of inserting and removing a capsule, for example a metal or
plastic, and will even allow the use of materials which could not be used up until now as they
did not provide sufficient flexibility or malleability or retraction capacity to be fitted around the
collar normally used, allowing the use of more cost-efficient materials. The fact that the outer
collar face and the outer wall face are flush with one another in their wide segment also
allows the inclusion of labels on that area without the drawback of the projection of a
conventional collar.
For storing and transporting bottles, it is common to arrange the bottles upright and
grouped together, leaving gaps between them, to place thereon a board provided with
perforations provided for being inserted around the necks of the bottles, such that said necks
project above said board, and to provide an additional level of bottles supported on said
board such that the bottle necks protruding from the board are arranged in the gaps existing
between said bottles of the upper level. This system can be repeated by stacking multiple
levels of bottles, maximizing storage. In this context, having a neck without protruding
projections such as the one proposed facilitates and simplifies the operations for placing, and
especially for removing, said boards provided with perforations on or from said bottle necks,
respectively, as the projections produced by the collares engage the board and make
removing it cumbersome.
Another additional advantage of the proposed solution is to facilitate the shearing off
of the capsule for its partial removal, as the annular outer recess serves as an unequivocal
guide for cutting the capsule as it is the only projection existing in the neck, preventing
confusion in consumers, and the inexistence of protrusions facilitates the extraction of the
upper portion of said capsule. This solution furthermore allows the edge created on the
capsule after it is cut, which may be sharp, to be bent into the annular outer recess created
around the neck of the bottle, preventing the risk of a user being cut.
The annular outer recess furthermore allows acting like a drip cap, preventing a drop
from running along the neck of the bottle, adhered thereby by surface tension, and staining
the hand of the person holding the bottle or the table or tablecloth on which said bottle is
placed. Said annular outer recess will retain said drop and interrupt its forward movement,
something that usual collar solutions do not allow.
Furthermore, since the width of the inner conduit is greater in the wide segment than
in the collar segment, producing a narrowing in the transition segment, a slight ramp is
produced inside the bottle neck which may allow retaining any dreg which may have reached
the bottle neck from the bottle body, where said ramp allows an additional retention of dregs.
This function is especially relevant in the case of containing wines, which tend to contain
dregs. Furthermore, this feature allows achieving the neck and the collar being externally
flush with one another without the entire neck having the thickness of the sum of the collar
and of the tubular wall, and therefore achieving a savings in glass and weight, and lower cost
of the bottle.
The collar segment and at least part of the transition segment are formed by the
molding process described above, whereas the rest of the transition segment and the entire
wide segment are formed by the blowing process described above. This is due to the fact
that with the initial molding process, only a straight inner conduit with a constant section or a
segment with a decreasing section can be formed, rendering it impossible to make an inner
conduit with an increasing section moving away from the mouth, as it would be impossible to
remove the mold of the inner conduit through the mouth. Therefore all the parts of the bottle
neck in which the dimension of the inner conduit is larger than the dimension of the inner
conduit of the collar segment are necessarily produced during the blowing step.
It is additionally proposed that the length of the tubular wall covered by the annular
collar is greater than the length of the tubular wall on which the annular outer recess is
defined, with the width of the annular outer recess preferably being equal to or less than 5
mm. However in some cases, such as in bottles with a crown cork pressed around the
mouth, for example, it is contemplated that said annular outer recess may be larger to allow
housing the crown of the stopper, leaving space so that an opener can access the mentioned
crown.
According to an additional embodiment, the mentioned annual outer recess is
confined between one of the annular collar projections and an annular wall projection, facing
said annular collar projection, with the annular wall projection being defined by an abrupt
change in size between two successive cross sections of the outer face of the transition
segment. Therefore, the outer wall face of said transition segment can abruptly change in
section, determining an annular wall projection facing the collar projection and similar or
identical to same, determining a much more defined annular outer recess.
Preferably the width of the annular outer recess will be equal to or less than its depth.
In said collar segment, the thickness of the annular collar will be added to the
thickness of the tubular wall, for example in at least the largest part of said collar segment,
but preferably in the entire collar segment, with an annular collar projection being flush with
the mouth. This solution prevents the formation of a step next to the mouth of the bottle neck
and offers better support for the corkscrew.
The thickness of the tubular wall of the wide segment is proposed to be comprised
between 80% and 120% of the thickness of the tubular wall of the annular outer recess of the
transition segment. It is thereby assured that said recess will not constitute a perceivable
weakening of the strength of the bottle neck, preventing the risk of the bottle neck breaking at
said annular outer recess.
It is additionally contemplated that the inner conduit of the collar segment may contain
a cork or plastic stopper tightly fitted therein. It is assured that the stopper is held inside the
inner conduit along its entire length by means of the precise control of the tolerances
mentioned above.
It is furthermore proposed that a capsule externally and tightly covers at least the
mouth, the collar segment, and the transition segment, and also at least part of the wide
segment as well.
Said capsule can have a portion at least partially inserted in said annular outer
recess, providing it with grip and on said bottle neck.
The capsule can alternatively or additionally be attached to the neck of the bottle by
other means, for example by means of adhesives, or by means of a slight tapering of the
outer collar face and/or of the outer wall face, with the widest end being the closer to the
mouth.
It is also proposed that at least one of the following elements has a cylindrical
geometry:
• the inner conduit of the collar segment and/or of the wide segment, and/or
• the outer wall face of the collar segment and/or of the wide segment, and/or
• the outer collar face.
It is proposed that at least part of the outer collar face and/or at least part of the outer
wall face of the wide segment is printed, silk-screened, engraved, or labeled with an
adhesive label, or preferably that both faces are at least partially covered by a common
printed, silk-screened, or engraved motif or labeled with an adhesive label. This feature is
possible as a result of both faces being flush with one another and therefore have a visual
continuity only briefly interrupted by the annular outer recess, which allows a motif distributed
between the outer collar face and the outer wall face of the wide segment to be perceived by
a user as a continuous motif. This opens up many design possibilities that used to be
inexistent as a result of the proposed invention.
According to another additional proposed embodiment, the transition segment
includes a recess portion adjacent to the collar segment, where the annular outer recess is
defined, and a wide portion adjacent to the wide segment from the outer wall face of which
they project protrusions defining at least one screw thread for screwing on a complementary
cap. This embodiment allows the creation of a bottle neck provided with a thread located
farther away from the mouth than the collar, such that when the cap is attached to the thread
the collar is concealed by the cap.
Said thread could be produced by means of a molding process prior to the blowing
process, thereby assuring a precise manufacture.
It is furthermore considered that the wide segment, arranged after the wide portion of
the transition segment provided with the screw thread, connects with bottle shoulders, said
wide segment having a length equal to or less than 5 mm. The scarce length of said wide
segment, of a few millimeters, allows bringing the screw thread as close as possible to the
shoulders of the bottle, allowing the cap to be virtually in contact or in contact with the
shoulders of the bottle when said cap is coupled to the thread, eliminating a groove where
dirt may build up or which can make it difficult to put labels on the bottle, in addition to
providing the assembly with a distinctive, especially when the annular outer face of the cap
screwed onto the screw thread is coplanar with the annular outer face of the body of the
bottle located below the shoulders.
According to another embodiment that is provided, a ring made of an elastic material
is inserted in the annular outer recess for fixing accessories to the neck of the bottle. This
allows fixing, for example, a stopper for the mouth of the bottle by means of a flexible arm,
with said stopper being attached to the neck of the bottle through said ring made of elastic
material when it is not stoppering the mouth of the bottle. Other accessories may be fixed to
the neck of the bottle, such as, for example, promotional products, free samples, labels, etc.
It will be understood that references to geometric position, such as, for example,
parallel, perpendicular, tangent, etc., allow for deviations of up to ±5º with respect to the
theoretical position defined by said nomenclature.
It will also be understood that any range of values that is offered may not be optimal
at its extreme values and may require adaptations of the invention so that said extreme
values are applicable, with said adaptations being within reach of one skilled in the art.
Other features of the invention can be found in the following detailed description of an
embodiment.

Detailed Description of an Embodiment
Figure 1 shows a view of a first embodiment of the tubular glass bottle neck with an
illustrative and non-limiting character. In this embodiment, it is proposed that the bottle neck
has a circular section, although it may naturally be oval, square, rectangular, or of any other
forma without this affecting its features.
The proposed neck consists of a tubular wall 10, defining a tubular conduit 12, an
outer wall face 11, and a mouth 13, where the tubular conduit 12 communicates the inside of
the body of the bottle, connected to the tubular neck, with the outside thereof.
On said outer wall face 11 of the tubular wall 10 there is located an annular collar 20,
in the form of a protruding flange attached on the tubular wall 10, with the thickness of the
glass of the tubular wall 10 being added to the thickness of the glass of the collar 20,
generating a portion of the bottle neck with a thickness greater than that of the rest of the
tubular wall 10. The mentioned collar 20 consists of an outer collar face 21, with this being
the most exposed face of the collar 20, demarcated by two annular collar projections 24,
which separate and space the outer collar face 21 from the outer wall face 11.
The mentioned collar 20 and the tubular wall 10 will be made of one and the same
material and will be integral with one another, formed of a single part. Up to this point the
description corresponds to the existing state of the art shown in Figure 4.
According to the embodiments shown in Figures 1, 2, and 3, the segment of the bottle
neck where the collar 20 and the mouth 13 are located is referred to as collar segment A.
According to the proposed invention, two other segments are defined in continuity with said
collar segment A, which segments are, in this order, transition segment B and wide segment
The mentioned wide segment C has its corresponding outer wall face 11 flush with
the outer collar face 21, and the inner conduit 12 of the wide segment C has a cross section
with a size greater than the cross section size of the collar segment A. The widening of said
inner conduit from the collar segment A to the wide segment C occurs in the so-called
transition segment B, which is placed between and connects both segments, with the
successive cross sections of the inner conduit 12 of the transition segment B having an
increasing size to produce said widening.
The outer wall face 11 of the transition segment B also transitions from the cross
section size of the outer wall face 11 of the collar segment A, to the cross section size of the
outer wall face 11 of the wide segment B, with at least two successive cross sections of the
outer wall face 11 of the transition segment B having a different size. Said change in the size
of the outer wall face 11 generates an annular outer recess 30 between the collar 20 and the
wide segment C.
According to the first embodiment shown in Figure 1, the transition of the outer wall
face 11 of the transition segment B is a gentle transition, with the annular outer recess 30
therefore being generated such that it is confined between an annular collar projection 24
and a gentle slope of the outer wall face 11 of the transition segment B.
However, and according to the embodiment shown in Figures 2 and 3, said transition
in the cross section size of the outer wall face 11 can be abrupt. In that case, an annular wall
projection 14 is generated perpendicular to the outer wall face 11 facing the annular collar
projection 24 confining the annular outer recess 30.
In this embodiment, furthermore, the annular collar projection 24 closer to the mouth
13 is located flush with said mouth 13. An additional step of the proposed bottle neck which
may make it difficult for a capsule 50 to be secured on said bottle neck is thereby eliminated.
Furthermore, the elimination of said step, combined with the outer collar face 21 being flush
with the outer wall face 11, causes the collar 20 to visually disappear. In this case, and for the
sake of comprehension, it will be considered that the thickness of the tubular wall 10 in the
collar segment A is equal to the thickness of the tubular wall 10 in the wide segment C, with
the remaining thickness being the thickness of the collar 20, or that it is equal to the smallest
thickness of the tubular wall 10 in the annular outer recess 30. In all the attached figures, the
imaginary separation existing between the collar 20 and the outer wall face 11 on which it is
placed is indicated with a discontinuous line.
In all the embodiments that are shown, the minimum thickness of the tubular wall 10
in the annular outer recess 30 is equal to the thickness of the tubular wall 10 in the wide
segment C, thereby preventing said annular outer recess 30 from being a weakening of the
bottle neck. However, it is considered that there may be certain thinning of up to 20% of said
thickness without generating a substantial weakening of the bottle neck in said annular outer
recess 30.
Figure 3 shows the same embodiment as Figure 2, but with a cork stopper 40
inserted inside the inner conduit 12 of the collar segment A, and with a capsule 50 covering
the mouth 13, the collar segment A, the transition segment B, and part of the wide segment
C. In this embodiment, the capsule 50 is narrowed coinciding with the annular outer recess
, with said narrowing being partially inserted inside the annular outer recess 30, retaining
the capsule 50 in its position.
The mentioned annular outer recess 30 can therefore be used as a guide for the
shearing off of the capsule for its partial removal, freeing access to the stopper 40 inserted
inside the tubular conduit 12.
Figure 5 shows an embodiment of a of bottle neck provided with protrusions acting
like a screw thread 60.
According to this embodiment, the transition segment B is divided into a collar portion
B1 adjacent to the annular collar 20 and containing the annular outer recess 30, and a wide
portion B2 adjacent to the wide segment C and containing the mentioned screw thread 60
protruding from its outer wall face 11.
This embodiment allows placing the annular collar 20 above the screw thread 60,
closer to the mouth 13, and when the cap is placed the annular collar 20 is concealed inside
the cap without said annular collar 20 being an impediment for access of the cap or its screw
thread, since the annular collar 20 is flush with the outer wall face 11 from which the screw
thread 60 of the bottle neck projects.
In the embodiment shown, the wide segment C is furthermore connected to bottle
shoulders 70 which widen the body of the bottle with respect to the neck of the bottle. In this
embodiment, the length of the wide segment is very short, less than 5 mm, such that the
screw thread 60 is adjacent to said shoulders 70. This allows the cap to be adjacent or in
contact with said shoulders when said cap is attached to the screw thread 60, thereby
reducing or eliminating the groove typically existing between the cap and the shoulders of the
bottle.
This embodiment is especially useful for the producing jars, for example for food or
cosmetic use.
Figure 6 shows another embodiment of the bottle neck identical to the one shown in
Figure 2, in which a ring 80 made of an elastic material has been inserted inside the annular
outer recess 30 defined in the transition segment B. Said ring 80 serves as an anchor for
attaching accessories to the neck of the bottle. In this example, the ring 80 has been used for
attaching it to a stopper of the mouth 13 of the bottle by means of a flexible arm, thereby
achieving that the stopper remains attached to the neck of the bottle after being removed
from the mouth 13, preventing it from being lost.
As will be understood, other accessories can be attached to the ring 80, such as, for
example, promotional products, advertisements, gifts, labels, metering devices, cups or
glasses, etc.
Figure 7 shows another embodiment suitable for the placement of crown corks, for
example, for beer bottles covered with a cap provided with a crown. In this embodiment, it is
proposed that the collar produces the annular projection around which the crown of the cap
is closed, with the collar being completely surrounded by said cap, and with the crown of the
cap being partially inserted inside the annular outer recess defined in the transition segment.
This embodiment furthermore proposes that the transition segment defines in the outer wall
face a ramp-like portion below the annular outer recess, which allows the insertion of an
opener inside the annular outer recess to enable acting as a lever on the crown of the cap for
the release thereof.
It will be understood that the different parts forming the invention described in one
embodiment can be freely combined with the parts described in other different embodiments
even though said combination has not been explicitly described provided that the
combination does not entail any drawback.
