The present invention relates to tamper-proof closure/seal for containers. In particular, the present invention is directed toward a tamper-proof closure/seal for wine bottles.
Product tampering has become a worldwide problem. This problem first came to light with the Tylenol tampering cases of the 1970s. In that era, many products were sold in packages which could be readily opened, manipulated, and re-sealed without any evidence of tampering taking place.
In order to restore consumer confidence, as well as limit product liability, various tamper-evident seals and the like have been applied to various food and pharmaceutical products. These seals provide ready evidence that a product has been opened, and possibly tampered with, so that a user will be aware that possible product tampering has taken place and will know not to purchase or use the product.
Note that in the industry, the terms “tamper-proof” and “tamper-evident” are sometimes used interchangeably. A “tamper-proof” seal may not, as the name implies, prevent tempering, but rather provide “proof” that such tampering has occurred. In the context of the present invention, both meanings may apply to the invention, as various embodiments of the invention may provide evidence of tampering as well as prevent or reduce likelihood of such tampering.
Most of the Prior Art tamper-evident seals are of the nature of a plastic shrink-wrapped collar or the like placed around the neck of a bottle or container. If the bottle or container is opened, the collar breaks, thus indicating to others that the container has been tampered with. Many manufacturers call such devices “freshness seals” to alleviate consumer fears of product tampering.
However, recent events have given rise for a need for increased security with result to food and pharmaceutical products. While the Prior Art collar seals and the like may indicate when a product has been opened, there may be other means by which a product tamperer could tamper with the contents of a container without being detected.
With wine bottles and other liquid containers, for example, a hypodermic needle or the like could be inserted into the cork of a wine bottle and a foreign agent injected into the bottle. By contaminating even a small number of such bottles, a product tamperer could wreak havoc. As it would be nearly impossible to spot the tiny hole left by the hypodermic needle, entire lots of wine or other product bottles or containers would have to be destroyed, at a great cost to the seller. Moreover, consumer fears of such tampering could destroy sales of such products for days, weeks, months, or even years.
Sayre, U.S. Pat. No. 5,654,022, issued Aug. 5, 1997 and incorporated herein by reference, discloses a heat shrink capsule for closing flanged bottle tops. Sayre discloses using an opaque, preferably metal disk bonded to the heat shrink capsule for protecting the cork against contamination and tampering. While such a metallic barrier may be useful in preventing tampering, a suitably drilled hole or the like could be used to overcome such a device. A consumer might not notice such a hole or assume the hole was part of the normal packaging appearance (e.g., if drilled centrally).
Thus, a need exists in the art for a type of seal for wine bottles and other containers which will provide obvious evidence of tampering, particularly by hypodermic needle or the like. The need also exists in the art for a type of seal for wine bottles and other containers which will make such tampering difficult to accomplish.
In the present invention the bottle or container to be secured is provided with a plastic sleeve with a clear plastic top, providing a view of a safety capsule. The plastic sleeve may be provided with small holes, allowing air to enter within the air space underneath the plastic sleeve. The safety capsule is kept in place with an attachment point to the plastic sleeve.
If any tampering occurs such as using an injection needle to enter the bottle through the cork, the safety capsule may be punctured, casing its color to change (e.g., from white to red). This color change is a warning to the end user and seller that a toxic attack to the contents may have occurred.
The safety capsule may comprise, for example, a plastic capsule or the like containing a chemical fluid which changes color when exposed to air. Alternately, the safety capsule may contain a paper or plastic disc provided with printed indicia or the like which will change color when exposed to air. Thus, for example; a warning message may appear on the paper or plastic disc alerting the user to a possible tampering event.
In addition, the safety capsule also provides a smooth surface in which a puncture hole or the like will be more readily apparent to the end user. A natural or synthetic cork may tend to re-seal itself around a hypodermic puncture wound, and thus provide no lasting evidence of such a intrusion. The safety capsule, in contrast, may readily show evidence of such a puncture.
The safety capsule may also incorporate a metal backing plate made of a thin but hard metal such as steel. Such a backing plate may prevent hypodermic needles and the like from entering the bottle, and thus discouraging such types of attack. The backing plate may also be made from a hard plastic, which is resistant to punctures.
The safety capsule may be attached to a plastic sleeve or the like which may be shrink-wrapped to the neck of the bottle such that the device may not be removed without providing evidence to a consumer that it has been previously removed. The safety capsule may also be incorporated into a traditional wine bottle foil sleeve or the like so as to provide a traditional appearance to the bottle assembly.
If any tampering occurs such as using an injection needle to enter bottle 1 through cork 4, safety capsule 8 may be punctured, casing its color to change (e.g., from white to red). This color change is a warning to the end user and seller that a toxic attack to the contents may have occurred.
Alternately, safety capsule 8 may contain a paper or plastic disc provided with printed indicia or the like which will change color when exposed to air. Thus, for example, a warning message may appear on the paper or plastic disc alerting the user to a possible tampering event.
Radial ridges 6 may be used, for example, in an embodiment in which safety capsule 8 is provided with a colored pressurized fluid therein. When punctured, the pressurized fluid may escape through the puncture hole and be exposed onto an absorbent paper disc or the like (not shown) placed above safety capsule 8. Thus, the material within safety capsule 8 need not react with air in order to be seen by the consumer.
Alternately, safety capsule 8 may be made of a translucent material such that the color of the pressurized fluid within is not apparent to the consumer. When punctured, the fluid will escape under pressure into the air space beneath plastic sleeve 5, alerting the consumer that the product may have been tampered with. The pressurized fluid may be non-toxic, of course, and a message may be printed on plastic sleeve 5 to “remove before use” so that a user will not attempt to put a corkscrew through plastic sleeve and safety capsule 8.
In addition, safety capsule 8 may provides a smooth surface in which a puncture hole or the like will be more readily apparent to the end user. A natural or synthetic cork 4 may tend to re-seal itself around a hypodermic puncture wound, and thus provide no lasting evidence of such a intrusion. Safety capsule 8, in contrast, may readily show evidence of such a puncture.
Safety capsule 8 may also incorporate a metal backing plate made of a thin but hard metal such as steel. Such a backing plate may prevent hypodermic needles and the like from entering bottle 1, and thus discouraging such types of attack. The backing plate may also be made from a hard plastic, which is resistant to punctures.
Safety capsule 8 may be attached to plastic sleeve 5 or the like which may be shrink-wrapped to neck 2 of bottle 1 such that the device may not be removed without providing evidence to a consumer that it has been previously removed. Bottle 1 may be provided, for example, with an enlarged portion 3 at neck 2, such that plastic sleeve 5 cannot be removed without breaking plastic sleeve 5. Safety capsule 8 may also be incorporated into a traditional wine bottle 1 foil sleeve or the like so as to provide a traditional appearance to bottle 1 assembly.
While the preferred embodiment and various alternative embodiments of the invention have been disclosed and described in detail herein, it may be apparent to those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope thereof.
