The lid can also include at least one outwardly extending lid flange with a contact surface at the periphery, as well as a lid sealing section. The base sealing section and the lid sealing section can together form a reclosable snap fit when the lid is forcibly applied to the opening of the base to generally close the opening. Further, the base flange and lid flange can be in at least approximate alignment when the opening is closed such that the lid and base flanges can be manually pulled apart to separate the lid and base and overcome the snap fit. The lid and base flanges can also inc lude a removed portion to create an increased distance between contact surfaces on the lid and base flanges at least one region. The tamper-evident, closed band can attach at a first end to one of the base and lid substantially along its entire periphery. At a second end, the band can have a free end. The tamper-evident band can be substantially detachable from the base or lid as a closed band. The band can also extend to substantially prevent direct manual access to the lid and base flanges.

Description

EVIDENT ALTERATION CONTAINER WITH EXTENDED BAND Background of the Invention Field of the Invention The present refers, generally, to containers, and in particular, to obvious containers of alteration with extended bands.

Description of Related Art The retail markets have used rigid and flexible plastic containers to contain and present items of perishable and fragile food, both hot. as cold, such as items of sandwiches, salads and bakery. These traditional papers of plastic packaging are now the minimum standards expected, and the requirements placed on the plastic packaging of food continue to expand as the demands placed on it increase. The presentation, the presence of the brand, the wishes of the consumer, the added value to improve the commercial competitiveness, the differentiation, the image and psychology have caused that the design and the application of the plastic packing become more challenging. Convenience continues to shape the future of packaging, with consumers gravitating toward packaged items of convenience that minimize the impact on their behavior by forcing packaging manufacturers to include social and environmental considerations in their development processes.

Rigid food plastic containers are manufactured, typically, from Polystyrene, Polypropylene, Polyethylene Terephthalate (PET), Polylactide, Polyvinyl Chloride (PVC) or other rigid polymers. Generally, these comprise any of a two-part tray. a base or could be of a one piece construction with a joint that modifies a portion of the container that acts as the base and the other connected portion that acts as a lid. This general configuration of food containers in a wide variety of configurations and cross sections (circular, rectangular, square and elliptical, etc.) has been available in the market for many years.

However, a limitation or concern has not described the possibly malicious entry into these containers that may lead to inadvertent or unintentional contamination of the contents of the food container. This has created an increase in the awareness and demand for food packaging systems resistant to alteration and evident alteration. The tampering or alteration of the product has been in existence as long as there have been goods packaged for consumption. The causes of tampering or alteration are varied but, in general, have one of two forms: the first is the malignant alteration, and the second is personal gratification, where a person takes or takes a sample of a product, and returns it to the shelf and the next customer does not notice the contamination. Both modes of tampering or alteration compromise the safety and quality of the contents of the food package. The costs of the alteration are enormous. In addition to the removal of the altered product, as well as the undisturbed product, the resulting negative publicity can lead to a reduction in the brand's income and equity, with retailers being forced to stop buying one or more products of the affected company or even in litigation.

In 1982, Johnson & Johnson (J &J) experienced this situation when numerous bottles of their 'Extra-Strength Tylenol' capsules had been linked with cyanide. At the end of the crisis, J &J had spent $ 100 million withdrawing 31 million. of bottles, this stopped the production of. product and also demanded the redesign of their bottles. Seven people died from the ingestion of the pills linked with cyanide. The threat of alteration has been amplified with the awakening of the terrorist attack of September 11, 2001. The possible contamination of food product on a possibly larger scale has been considered.

In the packaging industry, tampering or alteration is interference with the contents of the packaging, and the risk of alteration is a phenomenon in which we have to accept as a necessary perversity when purchases are made. At present, it is impossible to find food packings that do not have a safety feature. In virtual form, each packaged food product is enclosed or is joined with an evident safety feature of alteration or alteration proof. The term undue or obvious tampering means that a package that has undergone the alteration will show some signal that can be easily observed that the alteration has been made; the signal could be audible or visible. The opinion of the inventor is that in addition to its functions of protection of the product inside against physical and microbiological hazards and the entry of oxygen, and to provide brand recognition and product differentiation in the market, the packaging also has It must be designed to protect the consumer against alteration, whether deliberate or accidental.

The methods developed and currently used to combat the alteration have included the joining of the edges of the existing packages. The advantage of this procedure is that protection against alteration could be achieved without changing the packaging design. Alternatively, the clear or printed shrink wrapping has been used on the union of the neck edge between the lid and the tray or the whole of the container that holds the package and its contents safe. These methods provide some guarantee to the consumer that the product has not been interfered with. Similarly, other attempts developed to combat the alteration of the packaged product include protections below the lid (eg, heat-sealed pop-up covers, glued boxes and tape seals).

However, a limitation associated with these methods is that they only achieve a low level of evident packing of alteration. These are not visible, enough or differently, to the consumer, or they can be returned to their original condition with a glue gun and a hair dryer. This additional removal of the unused sealing material causes a safety problem since the unused seal intact could be used to seal the contaminated product again.

It would be advantageous for consumers if these were a simple method that could indicate quickly if a rigid plastic container of food has been interfered with, that is, opened and subsequently, has been reclosed before purchase.

Since it is extremely difficult to develop the product packaging that is considered as totally tamper-proof, the efforts of. The packaging industry has been directed to develop solutions that could guarantee that any alteration can be clearly visible to the possible consumer. In response to consumer demands, retail retailers continue to look for new plastic packaging solutions to improve the safety, convenience and, therefore, the degree of commercialization of the food product.

As such, the inventors recognize that the greatest utility of these rigid plastic containers could be obtained through improved methods of transportation in closed containers and designs that increase consumer safety while still maintaining both of the functional aspects required from packed in rigid plastic. The present invention fulfills this need.

Detailed Description of the Preferred Modalities The following description and examples illustrate the preferred embodiments of a container system. The container system is described in the context of use with various food products. However, the principles of the present invention are not limited to food products. It will be understood by those skilled in the art in view of the present disclosure that the described container system can be used with other types of goods., which include but are not limited to haberdashery, fasteners, pharmaceuticals, chemicals, and the like. A person skilled in the art could also find additional applications for the devices and systems described herein. In this way, the illustrations and descriptions of the container system in connection with the food simply exemplify some possible applications of the container system.

To help in the description of these components, the following coordinate terms are used. Figure 1 represents a Cartesian coordinate system x-y-z, with the container system being mainly located in the x-y plane. As described herein, terms such as "height" refer to the distance in the z-direction, and the terms "higher / up" and lower / down "refer to the positive z-direction. In a similar way, terms such as "outward" and "inward" refer, in a general way, to the directions in the xy plane and directed, generally, outward or toward the center of the container system Similarly, terms such as "lateral" will refer to the x-direction and "longitudinal" will refer to the "y-direction." Detailed description of a preferred embodiment of the container system is provided below. and its associated method of use.

Figure 1 depicts a container system 1 including a base 10 and a lid 40. As will be further discussed below, the lid 40 may include a band 60, as depicted herein. Base 10 can define a space in which food (or other products) can be inserted. The lid 40 can then be applied to the base 10 to close the space. As will be further discussed below, in the embodiment shown, the space can be sealed from the ambient atmosphere, so that the space is escape-proof. However, in other embodiments, the lid 40 and the base 10 can be combined to form a total or partially ventilated space, so that gases, liquids or larger particles can enter and / or exit.

In a preferred embodiment, the container system 1 as a whole can be substantially composed of the same material, such as Polystyrene, Polypropylene, Polyethylene Terephthalate (PET), Polylactide, Polyvinyl Chloride (PVC), other thermoplastics, or other materials. However, other materials may be used. Furthermore, in the preferred embodiments, the material can be clear, so that the observer can see the contents of the container system 1 and can receive some verification of the freshness, quality and nature of the contained goods. However, in other embodiments, the materials may be frozen, darkened, pigmented, may have labels applied or may be treated in other ways.

Furthermore, as shown, the container system 1 has a generally square tubular shape. The base 10 can be tapered gradually from a smaller bottom 11 to a larger hole at its opposite end. However, other forms are possible. For example, the container system 1 may have a circular, triangular, hexagonal, ovoid or other cross-sectional shape. In addition, the container system 1 can have a variable shape in cross section and a size that could differ from that of the embodiment shown. As a relatively small example with respect to the shape, in some embodiments, the base 10 may include ribs along its sides.

As shown in Figures 2 and 3, the base 10 may include a lower part 11 and four side walls 13. As discussed above, when the container system 1 has a different shape, the number of the side walls may vary 13. Furthermore, as shown, the base 10 can be tapered downward, although this is not necessary in all modes. Also as shown, the base 10 may include a stacking ring 12. Generally, the stacking ring 12 can be coupled with the stacking ring 42 on the lid ^ 40. In this way, when two container systems are stacked 1, one over the other, the stacking rings 12, 42 can be coupled together and improve, significantly, the stability of the stacked system. In addition, the base 10 may include a hole, a flange 14 generally along its periphery, and corner flanges 16 generally at the corners. Still further, although not shown here, the base 10 may include a variety of traditional shapes such as a rib, indicia, gripping surfaces, and the like. Also, as will be described in more detail below, the base 10 may include various shapes that facilitate opening, closing and sealing of the container system 1.

As shown in Figures 4 and 4A, the lid 40 can have a shape generally similar to that of the base 10. More particularly, the lid 40 in the embodiment shown can have a shape that roughly matches that of the hole of the base 10. The lid 40 may include a wide portion 41 that forms, in general, the middle part of the lid 40. Further along the periphery, the lid 40 may include a stacking ring 42, as described in advance, to engage with the stacking ring 12 of the base 10. Still further towards the periphery, the lid 40 may include a flange 44 which can extend to the free end of the lid 40. At the corners of the flange 44, the lid 40 may include a corner flange 46. A grip surface 45 may be included in the corner flange 46, which includes an easy grip surface such as a textured surface. Further,. as shown in partial form in Figures 4D, 5 and 6, the corner flange 46 may include an elevated portion 47. The corner flange 46 may include a ramp that rises gradually on either side of the raised portion 47. .

As best represented in Figures 4D and 4E, the lid 40 and the base 10 can be combined to form a pressure adjustment seal together with its peripheries. Figures 4D and 4E represent these shapes adjacent to the corners and sides, respectively. Although the forms related to the sealing are substantially the same between these regions in the embodiments shown, in other embodiments, these may vary. For example, in some embodiments it may be desirable to provide a stronger seal along the walls and a weaker seal near the corners to facilitate opening of the container system 1 at the desired location.

As shown, the base 10 may include a sealing section 18 along the side wall 13. The sealing section may be formed by a portion of the side wall 13 that expands outwards as it extends toward up, forming a lower limit or clutch surface for the sealing section 48 of the lid 40. The sealing section 18 of the base 10 can then form a generally central biased cut, wherein the sealing section 48 of the lid 40 it may extend and press against the base 10. The sealing section 18 of the base 10 may then extend inward, forming an upper limit or clutch surface for the sealing section 48 of the lid 40. The lid sealing section 48 it can have similar shapes as the base sealing section 18, forming a protrusion that extends outwards. Then, the two sections 18, 48 can be brought together to form a pressure adjustment connection, wherein at least one of the sections is deflected to reach the sealed array that is represented. In general, the clutch surfaces can be continuous and facilitate the formation of a. seal. Alternatively (or additionally) the seal can be formed in the central section of the sealing sections 18, 48. In any case, in the embodiment shown, a pressure adjustment connection can be formed so as to additionally provide a seal. When the seal extends around the entire periphery of the container system 1, the space within the container can be isolated from the ambient atmosphere through a hermetic seal of liquid and / or gas. Advantageously, the embodiment shown can also be closed and sealed again.

In other modalities, the details of the seal and pressure adjustment may vary. For example, in some modalities the direction of the protrusions can be reversed. In addition, in some embodiments the shape of the seal may vary along the periphery of the container system 1. Still further, in some embodiments, a complete hermetic seal of liquid and / or gas could not be formed, such as where it is provided ventilation. A variety of additional variations is possible and contemplated in the embodiments of the invention. For example, in some embodiments, there may be a seal that is not pressure adjusting or vice versa, or the sealing and pressure adjustment functionality may be generated from separate structures.

As discussed above, the lid 40 and the base 10 can also include the flanges 14, 16, 44 and 46. As shown in Figure 4D, the corner tabs 16, 46 can be separated. In the embodiment shown, the spacing can be formed by the tabs that are being raised (lid) and lowered (base) outward from their respective contact surfaces 50, 26. The contact surfaces 50, 26 of the lid 40 and the base 10 can limit, in general, the translation of the lid 40 towards the base 10. ' In addition, the contact surface 26 on the base 10 can provide support to the lid 40, preventing a lower lid 40 from deforming excessively or breaking when a load is supported above. The contact surfaces 50, 26 can also be configured to support the cover 40, sufficiently, so as to support the application of the cover 40 in the base 10 during an automatic machine process. Although on the contact surfaces 50, 26 are 'shown to be horizontal, in other embodiments, they may be angled, curved, vertical or otherwise.

As further represented, the lid corner flange 46 can be raised from the lid contact surface 50, and the base corner flange 16 can be lowered, in general, by creating a distance between the corner flange. of cover 46 and the tab < of base corner 16, and also forming a lower contact surface 26C accessible for opening, for example, by means of a human finger. Comparing with Figure 4E, in which only the lid flange -14 is lowered and the base flange 44 is not, there may be less space between the flanges along the sides compared to the corners. Accordingly, in the embodiment shown, the corners can form a preferred place to hold, possibly to open the container system 1 by pulling the lid 40 and the base 10.

Also, the comparison of Figures 4D and 4? indicates that the contact area between the contact surfaces 50, 26 of the lid 40 and the base 10 may vary between the corners and other regions. As shown in Figure 4D, the base 10 may include two upward facing surfaces 26A, 26B, of which only the surface 26B contacts the contact surface 50 of the cover 40. However, in the Figure 4E, the entire base contact surface 26 can interact with the lid contact surface 50 along the edges of the container. In other embodiments, the relationships between the contact surfaces may vary in other modes. In addition, although the contact surfaces shown are generally flat, in other embodiments, they may comprise other shapes. Furthermore, as shown, the lid 40 may include contact surfaces, such as the contact surface facing down 36, which is generally opposite the separate contact surfaces 26A, 26C on the base 10.

Figures 4F and 4G represent alternative embodiments of the lid 40 and the base 10 in the corner portion (corresponding to Figure 4D). As depicted in the embodiment of Figure 4F, both of the lid corner tabs .. and base 46 ', 16' can be raised / lowered. Unlike Figure 4D, corner flanges 46 ', 16' both can extend a greater distance, making it easier to grip and separate. As shown in the embodiment of Figure 4G, the base corner flange 16"can not be lowered, or in the same 'vertical position as the contact surface 26". In this way, the distance between the lid and base corner tabs 46", 16" can be reduced. Although the embodiments depicted in Figures 4D-4F are described as representing corner or no corner positions, in other embodiments, their locations may vary.

As it is also represented in the figures, the lid 40 can be joined with a band 60. As best shown, the band 60 can be a closed band, forming a complete circle and / or having an annular structure. Advantageously, a full circle may require fewer cuts or similar steps to form the band 60. In addition, the entire band 60 may be removed once, as will be further described below. The band can be joined with the cover 40 on the detachment line represented as the perforated end 62. In some embodiments, the attachment points can be couplings by point, facilitating detachment at these points. However, in other embodiments, the band 60 may be joined to the lid 40 by other means, such as in the weakened portion, a portion of thinned material, a slot, adhered, bonded or other structures that may form a line of detachment The band 60 can be removable from the lid 40 through a variety of means such as peeling, pulling, cutting, separating, and so on. As shown, in Figures 4D-4G, the band 60 may extend downwardly from the lid 40 and substantially block the access to the free end 28 of the base 10. In addition, since the band 60 may extending completely around the periphery of the lid 40 and the base 10, this can block access to the entire free end 28 of the base. In this way, while the band 60 is in place, the fingers of the user can not easily access the flanges 14, 16 of the base 10. In this way, the base 10 can not be easily held, only its side walls 13 and bottom 11 are generally available. In addition, the lid 40 can not be easily held because its periphery is attached to the band 60, leaving only its upper side available.

As a result of this configuration, the container system 1 can not be opened easily while the band 60 is in the position shown. However, the band 60 can be removable from the lid 40 and can have a free end 64 that can be easily accessed. In this way, a person can hold the free end 64 of the band 60 and can pull it off the lid 40, exposing the tabs of the lid 40 and the base 10 and allowing the opening of the container system 1. Advantageously, the band 60 can be substantially symmetrical without any specific tongue for pulling. In this way, the band 60 can be removed from either side. The asymmetry also allows a label to be applied on any side wall 13 without the need to identify which side has to be the "front" or "back" side.

It will be noted that the additional embodiments of this design are contemplated herein. For example, in some embodiments, the band 60 may be joined with the base 10 instead of the lid 40. In these cases; the band 60 can extend upwards, preventing access to the free end of the lid. In other embodiments, the portions of the flanges 14, 16, 44, 46 of the lid 40 and the base 10 can also be joined by a person for easy grasping therebetween. In these embodiments, the band 60 may extend only through a portion of the periphery. As another example, in some embodiments the band 60 can be joined with both of the cover 40 and the base 10, even though in the embodiments shown the band 60 is not joined with the base 10. It will be clear from the description herein that a wide variety of additional forms of band 60 is possible.

Furthermore, as shown, the band 60 can be joined with the lid 40 only in particular areas. For example, as shown in Figures 4 and 4D, the band 60 can be separated, generally, from the lid 40 adjacent to the corners (while joining on either side, as shown in Figure 4E). This may originate from the joining or coupling between the band and the lid that are previously cut on or near the corners, or at a removed portion as further described herein (ie, when the container is generally round) . In this way, the band 60 can be easily held and pulled from the lid 40 at the corners. As shown in Figure 8, this may facilitate the removal of the band 60 by pulling it upwardly enough to separate the band 60 from the lid 40 by pulling it with one hand and the side walls 13 of the base 10 with the another hand Alternatively, the upward traction of the band 60 in a corner can sufficiently expose the lid or base corner tabs 16, 46 to allow a person to grasp one of those in order to help separate the band 60. In a remarkable manner as shown in Figure 8, the entire band 60 need not be removed. Instead, in some embodiments it may be sufficient to just strip the band 60 in a corner. Furthermore, in these embodiments the band 60 can be firmly attached along the remaining edge with the lid 40, so that the band 60 only tears next to the corner. Alternatively, in some embodiments the band 60 can be uncoupled from the lid 40 next to the corner. For example, in embodiments where the web 60 is initially integrated with the lid 40, the line of attachment along the perforated end 62 of the web 60 may have a biased cut near the corner, so that they are decoupled in this way. region. In this way, the band 60 can be lifted more easily next to the corner.

More particularly, in some embodiments where the band '60 remains partially joined with the lid 40, the band can be detached along a specific portion of the length of the band-lid connection. For example, the band 60 can be detached along approximately 1/5 of the length. Furthermore, in order to prevent the lid 40 and the base 10 from separating before the strip 60 detaches, they may require a specific separation force greater than the force required to detach the strip. For example, lid 40 and base 10 may require a force at least approximately 0.09 kilograms (0.2 pounds) apart.

It should be noted that the band 60 may include a raised portion similar to the raised portion 47 of the lid 40 adjacent to its corners. In this way, the band 60 can generally coincide with the periphery of the lid 40 while providing a flat free end 64. As shown, the free end 64 of the band 60 may include a flange extending toward outside, facilitating the grip of the band 60.

In addition, to prevent unintentional opening of the container system 1, the band 60 may include the corner closures 68. Generally, the corner closures 68 may be adjacent the corners of the band 60 and form elongated protrusions that are extend inwardly that can interact with the tab 44 of the lid 40. The corner closures 68 can engage with the flange 44 underneath, generally concealing the upward movement of the band 60 relative to the lid 40 together to the corners. In this way, even when the band 60 could not be connected to the lid 40 together, at the corners, the 'corner' closures 68 can prevent unintentional relative movement. In some embodiments, corner closures 68 may have slightly different shapes and / or may be located at different points.

In addition, in some embodiments the corner closures 68 can hide the orifice of the container system 1 without tearing the container. For example, in some embodiments the band 60 can be separated from the lid 40 adjacent to the corners. In addition, as described above, the lid 40 and base 10 can be generally separated at the corners. In this way, in some embodiments it could be possible to lift the lid 40 and the band 60 together at the corners to expose the base flange 14. In these embodiments, the container system 1 could possibly be opened without detachment. To make this unidentified opening more difficult, corner closures 68 can be provided. Corner closures 68 can engage with the base flange 14 requiring an outward fold to pass the base flange. In this way, a larger movement of the band 60 may be necessary to lift and bend outwardly around the base flange 14. This increase in movement may be sufficient to induce the separation of the band 60 from the cover 40 to less at one point. This functionality can be particularly advantageous for modalities such as those discussed above with respect to Figure 8, wherein the band 60 is only separated at one corner.

In addition, how the band 60 is represented may include clues, indicating that a person may "JACK TO DETACH" (or another language). The band 60 may also include direction indicators, which further communicate a method for opening the container system 1.

In addition, in some embodiments the band 60 may include additional proportions susceptible to being detached. For example, in some embodiments an annular band 60 may include a detachment line which, depending on the detachment, converts the annular band into a strip. Furthermore, in some embodiments this additional detachment line can be configured not for detachment as a function of the separation of the band 60 from the lid 40. However, in other embodiments the band 60 can be configured to remain as an annular band without additional portions that can be detached or fragile.

Figures 8B and 8C represent alternative bands 60 and their engagement with the lid 40. As shown in Figure 8D, the band 60 may have a coupling portion 70 that can remain attached to the lid 40. The band 60 can be separated from the. coupling portion 70, | breaking the circle and leaving behind a portion. As shown, the coupling portion 70 can extend the full width of the band 60 and can be generally adjacent to the corner. Nevertheless, in other modalities its form and location may vary. Figure 8C depicts another band 60 with a coupling portion 70. However, in Figure 8C the band 60 may remain closed, and joined with the cap 40. In both embodiments, at least a portion of the band 60 may remain united with. the lid 40 once it has been removed to facilitate the opening of the container system 1. Advantageously, this may leave an indication that the container system 1 has been previously opened, in a possible manner. With the remaining portion absent, a person 'could not realize that the band 60 is still present, and in this way, does not realize that the container system 1 could have been previously opened.

In one method, of forming the container system described above, a base 10 can be formed through the molding, thermoforming, or the like processes. In addition, the cap 40 and the band 60 can be integrally formed in a similar manner. Then, perforations between the band 60 and the lid can be cut with a cutting tool, laser, or otherwise. Advantageously, the cap 40 and the band 60 can be modular with respect to the base 10, allowing bases 10 of different size to be used with any given combination of cap / band.

Then, the bases 10 can be loaded with a desirable product such as food, species, drugs, hygiene products, chemical products, and so on. The lid 40 (together with the band 60) can then be adjusted or snapped onto the base 10, providing a secure connection and in some embodiments, a seal. At this point, the container system 1 is closed and the band 60 indicates that it has probably not been opened since its initial closure.

· As described above, a person can then open the package by grasping a corner of the band 60 and lifting it upwards to detach it from the lid 40. Once the band 60 is removed enough to expose the tabs of the lid and base, these tabs can be pulled to open the container system 1. If desired, the container system 1 can be closed again, with the stripped band 60 indicating the previous activity.
