Description

CONTAINING WITH SUBJECTABLE DOME FIELD OF THE INVENTION This invention relates to plastic containers molded by blowing compressed air, and in particular, this invention relates to plastic containers that can be filled with hot liquids and have features to facilitate the holding of the container and lift it and Serve your content with greater security.

BACKGROUND OF THE INVENTION The conventional container molded by blowing compressed air of polyethylene terephthalate (PET) and which can be filled with hot liquids is generally characterized by having a body with a series of vertically elongated flexural panels arranged in regular spaces around the body to accommodate the shrinkage or volumetric contraction that occurs in the container due to the vacuum created once the container has been filled with hot liquid, closed with a screw cap or cooled to room temperature. The upper part, or dome of the container, is usually a circular cross section that has a central waist. Some people use this waist to hold the container with one hand when they pour their contents, but this is not convenient since the waist is too wide to be easily held. A stepped dome is easier to grasp, but does not facilitate the serving action of the container as it is located away from the center of gravity of the filled container. Currently, it has been necessary to create relatively long vacuum bending panels in order to accommodate the amount of vacuum induced contraction required to provide a container satisfactory to the market. Examples of this type of packaging are described in the following United States patents that belong to the beneficiary of this application: D366.416; D366,417; D366,831. Attempts have been made to incorporate handles to the containers that can be filled with hot liquids to allow serving the contents with ease and, in addition, accommodate the shrinkage induced by the vacuum of the container. An example of this type of packaging manufactured by the recipient of this application is described in the following United States patents: D344, 457; 5,392,937; and 5,598,941. The aforementioned packages have certain advantages and certain disadvantages. The conventional vacuum panel has the advantage of allowing the production of containers of relatively large size and with large surfaces for the placement of labels or labels; however, it has the disadvantage that this type of packaging is difficult to handle. On the other hand, containers with gripping panels have the advantage of relatively facilitating the action of pouring the contents for certain container sizes; however, it is difficult to include gripping panels in large containers and the areas for label placement are reduced. It is evident, therefore, that there is a need for a plastic container molded by blowing compressed air that provides both the ease of holding and serving the contents that containers with grip panels allow, as well as the existence of large surfaces for the Label placement, and avoid restrictions related to conventional vacuum panel packaging.

OBJECTS OF THE INVENTION With the foregoing in mind, a first object of this invention is to provide a novel clamped container that is easy to hold and also facilitates movement when pouring its contents. Another object of this invention is to provide a molded container by insufflation of compressed air that can be filled with improved hot liquids, which uses conventional vacuum panels together with a specially configured clamped dome that aids the vacuum panels to accommodate shrinkage of the container induced by vacuum due to filling the container with hot liquid, or by covering the container with a screw cap and by cooling. Another object of this invention is to provide a container with handles formed in its dome to facilitate the fastening and allow pouring the contents of the container with greater ease, while using shorter conventional vacuum panels to provide the container with a necessary balance to lift and serve ergonomically improved. A further object of this invention is to provide a molded container by blowing compressed air of plastic with a reinforced clamped dome resistant to distortion by forces caused by the hot liquid filling process.

BRIEF DESCRIPTION OF THE INVENTION More specifically, this invention provides a compressible container molded by insufflation of compressed air that has a body with a series of vacuum panels and a dome that incorporates gripping panels to facilitate the grip and to be able to pour the contents of the container with greater ease. In the illustrated embodiment, the dome has a non-circular cross section with elongated sides facing each other, having a pair of opposing gripping surfaces joined at their opposite ends by a cavity extending around opposite peripheral portions of the dome. The gripping surfaces are adapted to be taken between any finger and the user's thumb while the user's hand rests on the cavity. The dome is configured to allow the opposing gripping surfaces to flex towards each other to accommodate a predetermined amount of volumetric shrinkage due to filling with hot liquids, by closing the container with a screw cap and by cooling. The vacuum flex panels provided in the body below the dome accommodate an additional predetermined amount of volumetric shrinkage. In accordance with another aspect of this invention, the peripheral cavity of the dome includes a peripheral "antideformation link", or rib, to prevent undesired distortion of the dome. The rib allows a controlled amount of flexion so that the dome can accommodate a predetermined amount of volumetric contraction, but at the same time resists the "deformation" or twisting of the dome, which could distort the appearance of the dome.

DESCRIPTION OF THE PREFERRED MODALITY With reference to the drawings, Figure 1 illustrates a clamped container 10, particularly suitable for containing hot liquids. As best seen in Figure 1, the package 10 has a body 11, which may be of a tubular, cylindrical or rectangular cross section, with a variety of vacuum panels spaced around its circumference, such as panels 12 and 13. The body 11 of the container 10 has a cushion surface for adhering the upper label 16 and with a buffer surface for adhering the lower label 17, which extends continuously around the periphery of the body 11. The vacuum panels 12 and 13 are located between the damping surfaces for adhering labels 16 and 17, to accommodate the vacuum-induced shrinkage resulting from the contraction of the liquid due to the hot liquid filling process. In this way, the term vacuum-induced volumetric shrinkage as used in the present, if it refers to that shrinkage and not to the inherent thermally induced volumetric shrinkage. The vacuum panels 12 and 13 also include label support surfaces according to customer specifications 12a and 13a, for adhering a label (not shown) in the region between the upper and lower buffer surfaces for adhering labels 16 and 17, as is well known in this technique. A suitable base 19 is provided below the cushion surface to adhere the lower label 17. The base 19 is of conventional construction with relevant reinforcing ribs, such as radial ribs, to provide the preferred and desirable stiffening and anti-reverse qualities for a container that contains hot liquids, as is well known in this art. The package 10 has a dome 14 superimposed on the body 11. The dome 14 has a conventional flanged finish with threads (not shown) adapted to receive a screw cap. The dome 14 has an upper section 14a, an intermediate section 14b and an adjacent lower section 14c upper to the cushion surface for adhering the upper label 16. The dome 14 extends within a cylindrical plane up tangentially with respect to the damping surface for adhering the top label 16. As can be seen in Figure 3, the upper section of the dome 14a has a non-circular cross section that deviates outwardly and downwardly from the finish 15. Preferably, both the upper sections as the intermediate of the dome 14a and 14b, respectively, have elliptical cross sections in a plane perpendicular to the longitudinal axis AA extending in vertical direction through the center of the container 10. The lower section of the dome 14c also has an elliptical cross section that widens out in a circular shape outwards and downwards until merging with the circular surface cushions It is desired to adhere the upper label 16. As can also be seen in Figure 3, the main or longer axis BB of the elliptical sections of the dome 14 extends from front to rear of the container 10, and the minor or shorter axis CC of the Dome 14 extends from one side to the other of the container 10. The dome 14 has a pair of opposite lateral walls 14 ', 14' elongated and curved inwardly concave, joined at their ends to the terminal 14", 14" arched concave walls into. With reference to Figure 2, the upper section 14a of the dome 14 has an inwardly concave vertical cross section that shapes a chamber with a generally concave and bulging configuration. The upper section of the dome 14a terminates at a continuous undulating ripple edge 25 with a pair of opposite flattened apogee 25a and 25b located on the side walls of the dome, with a pair of opposed perigees 25c and 25d located on the terminal walls of the dome. Upon each apogee, such as the apogee 25a, there are flanges 26a and 26b for the objects that will be described later. The intermediate section of the dome 14b has a pair of elongated and transversely opposite elongated gripping surfaces 20 and 21 that penetrate deep into the dome 14 below the apexes of the gutter edge 25a and 25b, respectively, and are preferably concave outwards to facilitate the grip on the part of the user with the thumb and a finger, preferably the index. The gripping surfaces 20 and 21 extend equidistantly on the opposite sides of the longitudinal axis AA of the package, and are on, but adjacent to, the buffer surface for adhering the upper label 16. The cavities 23 and 24, which penetrate with less depth inside the dome 14 than the gripping surfaces 20 and 21, interconnect the gripping surfaces 20 and 21 at their opposite ends. The gripping surfaces 20 and 21 assist the peripheral cavities 23 and 24 to allow the user to place their thumb and index fingers on the gripping surfaces 20 and 21 and the palm of the hand in the corresponding region of the cavity 23 or of the cavity 24, to lift the container 10 and pour its contents either from the front or from the rear part thereof. The gutter edge 25 on the gripping surfaces 20 and 21 and the cavities 23 and 24 assist the anti-slip flanges 26a and 26b to provide a surface against which the user can place his index finger, thumb and hand, while supports the palm of your hand on the generally circular surface of the lower section of the dome 14c, when handling the container 10. In the illustrated embodiment (drawn in figures 1 and 2 to approximately half of its natural size) the container 10 has a nominal filling capacity up to the limit of 2,842 ml. The capacity of the body 11 to the buffer surface to adhere the upper label 16 is around 1,658 ml. The capacity of the dome between the cushion surface to adhere the upper label 16 and the upper part of the finish 15 is about 1,184 ml. As a result, the portion of the dome provides approximately 41% of the total volumetric nominal capacity of the container 10. As compared to a conventional vacuum panel container with a circular hood cross section with a capacity of 2,842 ml manufactured by the applicant, the volume of the bell constitutes around 30% of the total volume of the filled container until the stop. The center of gravity (CG) of the filled container is located at about 125 mm of the total height of the container 10 which is 292 mm when measured from a reference plane, as a horizontal surface on which the container has been placed . Preferably, the center of gravity of the filled container is on a scale of about 40% to about 45% of the total height of the container, or long, and the gripping surfaces 20 and 21 are located at a higher adjacent point to the center of gravity of the filled container on a scale of about 55% to about 65%, and more preferably about 60% of the total height of the container. It is convenient that the gripping surfaces 20 and 21 are spaced by a distance of about 75 to about 90 mm through the minor axis C-C of the illustrated elliptical cross section. The gripping surfaces have a total length of about 70 mm, and the shortest peripheral distance from the center of the gripping surface 20 to the center of the opposing gripping surface 21 is about 175 mm. The aforementioned dimensional and surface configurations help so that the container can be lifted and so that its contents can be served with ease. The package 10 is particularly apt to contain hot liquids. Under conditions of filling with a hot liquid at a temperature close to 93.3 ° C, closed with screw cap and cooled to ambient temperatures of around 22.2 ° C, body vacuum panels, such as panels 12 and 13, are bent inwardly as is well known in the art to accommodate volumetric shrinkage. However, unlike conventional hot liquid containers, in the container 10 of this invention the vacuum panels do not accommodate all the volumetric contraction of the container. Rather, in the package of this invention, the dome 14 accommodates approximately 5% of the total volumetric shrinkage of the package 10 that occurs due to filling with hot liquid, closed with screw cap and cooled. The remainder is accommodated by conventional vacuum panels, such as panels 12 and 13. In this invention, the gripping surfaces 20 and 21 are mounted to be bent inwardly and toward each other by flexible networks to accommodate the volumetric contraction in the dome 14. This flexional movement can be seen in figure 5, which illustrates schematically with dotted lines the inward deviation of the gripping surfaces 20 and 21 in their inward bending positions. The geometric configuration of the dome tends to allow bending mainly from side to side to provide the necessary gripping surface movement. Flexion occurs on two pairs of vertical axes of rotation located generally in the regions 20 ', 20"and 21 ', 21" illustrated in FIGS. 1 and 5. The shrinkage is also facilitated to some extent by a peripheral network region of articulations 28 having an inwardly concave surface (FIG. 2) adjacent to the joint of the section. intermediate of the dome 14b and of the lower section of the dome 14c together with the flashing edge 25 which is located above. As seen in Figure 2, the network of articulations 28 is convex inwardly relative to the upper and lower inflected spaced lines 28a and 28b, respectively, which extend peripherally around the dome 14. Preferably, the container it has means of reinforcement in the dome to avoid an unwanted distortion and allow, at the same time, the necessary amount of absorption by vacuum. The package 30, illustrated in Figures 9 and 10, is identical to the package 10, except for the peripheral reinforcement ribs 32a and 32b. For these objects, the container 30 has a finish 38 and a dome 34 with an upper section 34a, an intermediate section 34b and an adjacent lower section 34c upper to the cushion surface for adhering the upper label 36. The middle section of the dome 34b counts with a pair of opposing gripping surfaces 40 and 42 inserted into the dome 34 and allowing the user to take the container from the dome 34 between his index and thumb fingers. The peripheral cavities 44 and 46 are inserted in the middle section of the dome 34b and interconnect the gripping surfaces 40 and 42 at their opposite ends. The peripheral reinforcement rib or anti-deformation link 32a extends in the peripheral cavity 44 laterally between the gripping surfaces 40 and 42, and the peripheral reinforcement rib or anti-deformation link 32b extends in the peripheral cavity 46 laterally between the gripping surfaces 40. and 42. Each rib, 32a and 32b, is elongated transversely and extends to opposite ends of the gripping surfaces 40 and 42. As illustrated, the ribs 32a and 32b are concave outward, or in a C-shape. , in a vertical cross section and located in the deepest parts of the peripheral cavities 44 and 46. The opposing ribs 32a and 32b help to reinforce the dome 34 and prevent undesirable twists and deformations of the dome 34 that could occur during certain conditions absorption by vacuum thereof. In this way, the ribs 32a and 32b allow the clamped dome 34 to accommodate a predetermined amount of vacuum in a controlled manner, while preventing the flared shape of the dome 34 from deforming. If the package is not exposed to conditions that could cause the dome to be deformed, the use of the anti-deformation ribs or links 32a and 32b can be eliminated. As a result of the vacuum absorption of the dome, the vacuum panels of the body 11 are shorter in their vertical height than conventional bending panels because they are not the only means of absorbing the vacuum. By reducing the height of the vacuum panels and providing a predetermined amount of vacuum adsorption in the domes 14 and 34, it is possible to place the gripping surfaces 20, 21, 40 and 42 at a point slightly above the center of gravity of the filled 10 or 30 container, which facilitates the holding, lifting and serving of containers 10 and 30, unlike conventional cylindrical flexible vacuum panel containers having only circular dome cross section configurations with ergonomic restrictions that the characterize The dome configurations 14 and 34 provide not only ergonomically convenient attachment and serving qualities, but also provide containers 10 and 30 with excellent filling capacity. The lower height of the flexible panels reduces the height of the label, but still provides a larger surface to adhere the label than other containers for similar side walls. The broader dome allows the client to create designs and logos that stand out on it. Preferably, containers 10 and 30 are molded by blowing compressed air of PET plastic into a thermofixer mold using commercially available blow molding equipment. If the qualities of filling with hot liquid are not necessary, the flexible panels of the body can be eliminated and different plastic materials can be used. The containers 10 and 30 would continue to retain their ergonomic qualities for lifting and serving. Although a preferred embodiment of this invention has been described in detail, it is possible to make various modifications, alterations and changes without departing from the original spirit and scope of the invention, as defined in the appended claims.
