Detailed description of the invention

The detailed description set forth below in relation to the accompanying drawings is intended as a description of the various modalities of the subject or matter described, and is not intended to represent the only modalities in which the described subject or matter may be practiced. The detailed description includes specific details for the purpose of providing a deep understanding of the subject or matter described. However, those skilled in the art will appreciate that the subject matter or matter described can be practiced without these specific details. In some cases, well-known structures and components can be shown in block diagram form, in order to avoid obscuring the concepts of the subject or matter described.

The subject or matter described refers

<img file="MX341024B_D0014.tif" />

base for plastic containers, and systems, methods, and base molds thereof. In particular, the subject or matter described involves base configurations that have particular vertical geometries that aid or facilitate processing at elevated temperatures, such as hot content filling, pasteurization, and / or retort processing. Optionally, the plastic containers according to modalities of the subject or matter described can also be configured and operate to accommodate internal forces caused by post-processing at elevated temperatures, such as temperature-induced forces from various temperatures in transit to or in storage at a distributor (for example, wholesaler or retailer), for example Prolonged effects of product weight stored there over time, etc., and / or cooling operations, (including exposure to room temperature) after or between processing at elevated temperatures.

Generally speaking, in various embodiments, the plastic containers according to the embodiments of the subject or matter described have a base portion with a lower end having a vertical wall of a particular geometry. The vertical wall can resist movement in response to variations in pressure or forces within the

<img file="MX341024B_D0015.tif" />

container, and can facilitate movement together with a movable part of the lower container end.

Therefore, although a vertical wall remains stationary or substantially stationary, a portion of the bottom end of the container may move in response to internal pressures within the container, when, for example, it is filled with hot content and sealed. Optionally, the lower end portion can be constructed and operated to move downward and axially outward in response to internal pressures such as pressure in the space above or below the weight of the product, and also move upward and axially inward in response at a different internal pressure, such as an internal vacuum created within the container due to cooling or cooling processing of the container. Alternatively, the lower end portion may be constructed and operated to resist movement in one direction, for example, a downward and axially outward direction, in response to internal pressures (eg, pressure in the headspace, product weight, etc.), although it can be built and operated to move upward and axially inward in response to different internal pressure, such as an internal vacuum created within the container due to cooling or cooling processing of the container.

Meanwhile, the vertical wall can be '· · ΙΜΓΜ iCTfcl i I

INDUSTRIAL supports or supports part of the container vertically or substantially vertically, angling or tilting radially inwards. The vertical wall can be constructed and operated to remain stationary during movement of the movable bottom end portion of the container. Optionally, the vertical wall may be constructed and operated to move or flex radially inward slightly during movement of the movable lower end portion. Optionally, the vertical wall can be constructed and operated to move or flex radially outward during movement of the movable lower end portion. In the case of flasks, for example, the vertical wall may remain rigid or stationary in response to relatively higher temperatures and pressures, normally involved in flask applications.

In various embodiments, the vertical geometry may be of a stacked rib or ring configuration. Any suitable number of rings or ribs can be stacked, such as two, three, four or five. The rings can be directly stacked vertically on top of each other, or can be tapered inward with each successive ring. Alternatively, only one ring can be implemented. The use of vertical geometry, and in particular, stacked ring configurations according to modalities of the subject or matter described can provide the least material to form a bottle, for example, while providing desired container characteristics, such as stability of the container. container to compensate for internal pressure variations within the container after filling with hot content and sealing.

The plastic containers according to the modalities of the subject or matter described, can have any suitable configuration. For example, the embodiments may include vials, such as wide-mouth vials, and base configurations thereof. Modes may also include containers, singles, bottles, jugs, asymmetric containers, or the like, and the base configurations thereof. Therefore, the modalities of the subject matter or matter described can be filled with, and contain any suitable product including a fluid, semi-fluid product or viscous food product, such as apple sauce, spaghetti sauce, condiments, baby food, brine, jellies and the like, or a non-food product such as water, tea, juice, isotonic drinks or the like.

The plastic containers according to the modalities of the subject or matter described can be of any suitable size. For example, modalities include containers with internal volumes of 24 oz., 45 οζ., 48 οζ., Ο 66 οζ (0.68 kg, 1.27 kg, 1.36 - «- K¿k- * o - * - 1 institutítmexícano

OF THE PROPERTY

Also, the sizes of the container may include single and multi-portion containers. In addition, the modalities may also include containers with mouth diameters of 38mm, 55mm or greater, for example.

Hot content fill processing may include filling a product into the container at any temperature for example within the range of or about ΙδΟ'Τ (54.4 ° C) to or about 205 ° F (96.1 ° C) or within a range from about 185 ° F (85 ° C) to or about 205 ° F (96.1 ° C). For example, a wide-mouth bottle can be filled with a hot product at a temperature of or about 205 ° F (96.1 ° C). Optionally, the hot content fill temperature can be greater than 205 ° F (96.1 ° C), such as 208 ° F (97.7 ° C). As another example, a single-serving container, such as for an isotonic drink, can be filled with a hot product at a temperature of 185 ° F (85 ° C) or slightly below.

Plastic containers according to modalities of the subject or matter described, can be capped or sealed using any suitable closure, such as a plastic or metal screw cap or cap, an aluminum seal, a trailing closure, a cap or cap snap-fit ​​plastic or metal.
