AI Technical Summary
Existing beverage seals in the hospitality industry, such as reusable silicone covers or lids with pre-cut openings, are either reused multiple times, not customizable, or have pre-cut openings, failing to provide comprehensive coverage and protection against tampering or adulteration.
A disposable self-adhesive beverage seal made of flexible material with an adhesive layer, allowing piercing at any point and ensuring full coverage after use, with optional weakened zones for easier penetration, designed for single-use and direct beverage contact.
The seal provides comprehensive coverage and reduces the risk of foreign object or liquid introduction, addressing tampering concerns while being disposable and customizable.
Abstract
Description
[0001] The present technical teaching relates to a self-adhesive disposable beverage seal for the temporary covering of drinking vessels.
[0002] In the hospitality industry, particularly in bars, clubs, festivals, and at events, there is a risk that drinks may be tampered with or adulterated with unwanted substances while unattended. Known solutions include reusable silicone covers or lids with pre-cut openings. However, these have drawbacks, as they are either reused multiple times, not customizable, or already have a pre-cut opening.
[0003] The present technical teaching is based on the task of providing a disposable beverage seal that temporarily covers a drinking vessel, allows piercing with a drinking straw at any point, and continues to ensure extensive coverage of the vessel after piercing.
[0004] This task is solved by a self-adhesive beverage seal made of a flexible, flat material with a surrounding adhesive layer. Once applied to the rim of a drinking vessel, it forms a complete seal. The material is designed so that it can be pierced at any desired point by mechanical force using a drinking straw, without the need for pre-perforation.
[0005] Alternatively, the beverage seal can have a weakened zone in the central area in the form of a cross-perforation or material thinning, which makes piercing easier.
[0006] After piercing, the seal remains attached to the drinking vessel and covers the remaining opening area. The beverage seal is designed as a single-use product and is disposed of after a single use.
[0007] The beverage seal can be designed in any geometric shape that allows for a full coverage of the container opening.
[0008] The material of the beverage seal and the adhesive layer used are suitable for use in direct contact with beverages.
[0009] The full coverage of the drinking vessel reduces the risk of unintentional introduction of foreign objects or liquids.
Claims
[1] Self-adhesive disposable beverage seal for temporarily covering a drinking vessel, characterized by , that the beverage seal is affixed to the opening of the drinking vessel after it has been filled, forms a closed cover and can be pierced at any point by a drinking straw or a comparable drinking tube, whereby after piercing an opening is created which substantially corresponds to the cross-section of the drinking straw, while the predominant area of the opening of the drinking vessel remains covered by the beverage seal. [2] Beverage seal according to claim 1, characterized by that the beverage seal is made of a material suitable for direct contact with food. [3] Beverage seal according to any one of the preceding claims, characterized by that the beverage seal is provided with an adhesive suitable for direct contact with food. [4] Beverage seals according to any one of the preceding claims, characterized by that the beverage seal has a pre-formed predetermined breaking point, in particular in the form of a cross or slit perforation, which facilitates piercing with a drinking straw.
