Elastic safety drink cover
View Patent ↗A safety cover for a drink to prevent tampering, comprising a long cylindrical body that stretches over a drink glass in a way that is difficult to remove, high-friction features to make the cylindrical body even harder to remove from the glass, and a small opening for drinking or straw insertion that is difficult to use for unauthorized tampering of the drink.
1 . A safety cover for a beverage, comprising:
an approximately flat circular top cover, comprising a small sip opening close to an edge, comprising a thin elastic material, wherein the radius of the top cover is smaller than the radius of a drinking glass;
a cylindrical body projecting from the circular top cover, wherein the cylindrical body is configured so as to fit tightly around a drinking glass and to cover at least 75% of the height of a drinking glass;
at least two pull tabs placed on a distal edge of the cylindrical body in such a way as to assist in its installation or removal;
wherein the cylindrical body comprises an inner surface, wherein the inner surface comprises at least one high-friction surface;
wherein the at least one high-friction surface comprises a cylindrical ring, further comprising a recessed ring above the cylindrical ring, a second recessed ring below the cylindrical ring, and a lower cylindrical ring below the second recessed ring, with the lower cylindrical ring located at an edge of the cylindrical body.
2 . The safety cover of claim 1 , wherein the top cover and the cylindrical body are made of silicone rubber.
3 . The safety cover of claim 1 , wherein the top cover has a thickness of approximately 1 mm and the cylindrical body has a thickness of approximately 0.8 mm.
4 . The safety cover of claim 1 , wherein the top cover and the cylindrical body are translucent.
5 . The safety cover of claim 1 , wherein the top cover has a diameter of 2.5 inches.
6 . The safety cover of claim 1 , wherein the cylindrical body has a height of at least 2.5 inches.
7 . The safety cover of claim 1 , wherein the cylindrical body has a diameter that is less than a diameter of a drinking glass on which it is installed.
8 . The safety cover of claim 1 , wherein the cylindrical ring and the lower cylindrical ring have a height of approximately 5 mm.
9 . The safety cover of claim 1 , wherein a thickness of the recessed ring and the second recessed ring is approximately 0.5 mm, wherein a thickness of the cylindrical ring is 0.8 mm, and wherein a thickness of the lower cylindrical ring is 1 mm.
10 . The safety cover of claim 1 , wherein the sip opening has a diameter of no more than 5 mm.
11 . A safety cover for a beverage, comprising:
an approximately flat circular top cover, comprising a small sip opening close to an edge, comprising a thin elastic material, wherein the radius of the top cover is smaller than the radius of a drinking glass;
a cylindrical body projecting from the circular top cover, wherein the cylindrical body is configured so as to fit tightly around a drinking glass and to cover at least 75% of the height of a drinking glass;
at least two pull tabs placed on a distal edge of the cylindrical body in such a way as to assist in its installation or removal;
wherein the sip opening has a width of approximately 5 mm and a length of approximately 1 cm.
12 . The safety cover of claim 11 , wherein the sip opening comprises a lip around its perimeter, further comprising:
a sip plug that can close off the opening, wherein the sip plug comprises:
a ring that interlocks with the opening;
a plug attached to the ring that plugs into the opening and occludes it completely.
13 . The safety cover of claim 11 , wherein the top cover and the cylindrical body are made of silicone rubber.
14 . The safety cover of claim 11 , wherein the top cover has a thickness of approximately 1 mm and the cylindrical body has a thickness of approximately 0.8 mm.
15 . The safety cover of claim 11 , wherein the top cover and the cylindrical body are translucent.
16 . The safety cover of claim 11 , wherein the top cover has a diameter of 2.5 inches.
17 . The safety cover of claim 11 , wherein the cylindrical body has a height of at least 2.5 inches.
18 . The safety cover of claim 11 , wherein the cylindrical body has a diameter that is less than a diameter of a drinking glass on which it is installed.
