The groove walls 452 may be disposed between the front end portions of the thickened wall portions 446, and the rear wall 450 may be disposed between the rear end portions of the thickened wall portions 446. The spout walls 446 may form a spout 447, either alone or in conjunction with the trough wall 452. The breach walls 446 can be recessed, embossed, or thickened walls 466 (e.g., Figure 26). The spout walls 446 may extend in a string shape and may be generally straight as shown; however, in other embodiments, the walls 466 may be curved inwardly, outwardly curved, or any other suitable The shape. In any event, the breach walls 446 have a larger radial wall thickness than the rear and channel walls 450, 452.

The breach wall 446 can include a shoulder 448 that is disposed between the longitudinal center axis A of the container 422 and the lip sealing surface 454. The shoulders 448 can include a generally axially facing surface that extends transversely relative to the axis A.

In a first example, the shoulders 448 can be disposed in a plane that is perpendicular to the central axis A. In this example, the shoulders 448 can be coplanar with a descending portion 448' that extends circumferentially between the shoulders 448 such that a descending surface that continues along the circumference can be passed over the shoulders 448. And the descending portion 448' is established.

As shown in FIG. 23A, the shoulders 448 can be separated by a A plurality of corresponding surfaces of the neck terminal guide ring G are produced in a blank mold. The blank mold can include a neck ring N for at least partially establishing an exterior of the neck terminal 434 of the container 422, and a plunger P for at least partially establishing an interior of the neck terminal 434. Included are a breach wall 446 (thickened wall portion 466) and inner surfaces (e.g., inner surface 462); and a guide ring G that can establish shoulders 448, sealing surfaces 454, and the like.

In a second example, and with reference to Figure 27, shoulders 548 (not shown) can be disposed at a non-perpendicular angle relative to a longitudinal central axis A, thereby being axially inward. The direction extends into a container 522 and extends radially inwardly toward the longitudinal center axis A of the container 522. In this example, no extra descending parts are set. However, other embodiments may include a plurality of angled shoulders 548 and a descending portion extending circumferentially therewith.

Referring to Figure 27A, both shoulders 548 and the split walls 546 (e.g., thickened walls 566) can be produced in a blank mold by the corresponding surfaces of a plunger P'. The blank mold can include a neck ring N for at least partially establishing an exterior of the neck end 534 of the container 522, and a plunger P for at least partially establishing an interior of the neck terminal 534, including The breach wall 546 (thickened wall portion 566) and the inner surfaces (e.g., inner surface 562); and the guide ring G', which establishes the sealing surface 554, and the like.

The embodiments of Figures 27 and 27A are similar in many respects to the embodiments of Figures 1 - 26, and the same element symbols are generally designated the same or corresponding elements in the various embodiments. because Thus, the description of the embodiments is incorporated into each other, and the description of the common subject matter will not be repeated herein.

Referring to Figures 23, 23A, 27 and 27A, the shoulders 448, 548 are axially spaced from the planar sealing surfaces 454, 554 or axially concave relative to the planar sealing surfaces 454, 554. In fact, the shoulders 448, 548 can be recessed by an amount that is greater than the amount provided to a conventional descending portion of a conventional container. For example, the descending portion 448' can be axially recessed at least 0.020" from the sealing surface 454 and over 1 mm for a 35 mm finished product.

For purposes of illustration, referring to Fig. 26, a package 420 includes a container 422 and a sealed carrier cover member 424 that is sealed to the container 422. The cover member 424 includes a cover 423 that carries a seal 425. The cover 423 can include a base wall 423a and a skirt 423b extending from the base wall 423a and including one or more container engagement formations 423c for coupling to corresponding formations 442 of the container 422. The base wall 423a can include: one or more peripheral panels 423d extending radially and inwardly from the skirt 423b; and one or more central panels 423e extending radially inwardly from The surrounding panel 423d extends concavely or axially inward from the panel 423d. The seal 425 can be carried by the peripheral panel(s) 423d and carried substantially radially between the skirt 423b and the center panel(s) 423e.

The shoulders 448 (and 548) can be recessed such that when the cover member 424 is fully coupled to the container 422 as shown in Fig. 26, there is an axial gap between the shoulders 448 and the center panel 423e. More specifically, there is an axial gap between the shoulders 448 and the seal 425. Therefore, There is no interference between the shoulder 448 and the cover 423 and/or the seal 425. In the illustrated example, the cover 423 can be constructed of a metallic material and the seal 425 can be constructed of a polymeric material. In other examples, cover 423 and seal 425 can be constructed of any suitable material.

With continued reference to FIG. 26, the thickened wall portions 466 can extend from the shoulders 448 axially through the engagement formations 442 and/or flanges 444 into the container 422. For example, the thickened wall portion 466 can extend to one of the shoulders 432 of the container 422 to create a thickened shoulder 432'. In another embodiment, the thickened wall portion 466 can further extend axially to one of the side walls 430 of the container 422 to create a thickened sidewall portion 430'. Thus, the breach wall 446 or the thickened wall portion 466 can include the inner surfaces 468 of the container neck shoulders 434, the thickened shoulders 432', at least at locations corresponding to and below the shoulders 448. Inner surfaces 460', and inner surfaces 458' of the thickened side wall portions 430'. In any event, the thickened wall portion 466 extends radially inwardly relative to the central wall A relative to one or more of the inner surfaces 462, 464 of the rear wall and/or the groove walls 450, 452 so as to form a desired axis. The length and the product can be directed out of the inner tank of the container 422.

The container disclosed herein thus fully satisfies one or more of the previously stated objects and objectives. The present disclosure has been presented in connection with a plurality of illustrative embodiments and various modifications and variations. Other modifications and variations are readily apparent to those skilled in the art in the light of the foregoing description.
