DETAILED DESCRIPTION OF AN EMBODIMENT

(9) FIG. 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.

(10) 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.

(11) 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.

(12) 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 FIG. 4.

(13) According to the embodiments shown in FIGS. 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 C.

(14) 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.

(15) 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.

(16) According to the first embodiment shown in FIG. 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.

(17) However, and according to the embodiment shown in FIGS. 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.

(18) 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.

(19) 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.

(20) FIG. 3 shows the same embodiment as FIG. 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 30, with said narrowing being partially inserted inside the annular outer recess 30, retaining the capsule 50 in its position.

(21) 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.

(22) FIG. 5 shows an embodiment of a of bottle neck provided with protrusions acting like a screw thread 60.

(23) 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.

(24) 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.

(25) 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.

(26) This embodiment is especially useful for the producing jars, for example for food or cosmetic use.

(27) FIG. 6 shows another embodiment of the bottle neck identical to the one shown in FIG. 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.

(28) 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.

(29) FIG. 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.

(30) 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.
