Claims8
A tamper evident squeeze tube comprising:
- a hollow elongated tube having flexible walls;
- a sealing means at one end, which end is used for filling the tube prior to sealing;
- a dispensing head at the other end comprising:
- a neck having an opening therein to the interior of the tube;
- and
- a frangible sealing member mounted across the opening for sealing the opening and indicating tampering with the contents therein;
- a cap adapted to be mounted to the exterior of the neck which cap includes a chamber for enclosing the sealing member when the cap is mounted to the neck and coating with the neck and sealing member to prevent the sealing member from fracturing while the tube is being filled, said sealing member being integral with the neck and being of a flexible dome shape, the interior of the cap including means for forcing the dome into the interior of the opening while the cap is being mounted to the neck and maintaining the dome therein while the tube is being filled.
A tube cap for mounting to the neck of a squeeze tube, said neck having an opening therein to the interior of the tube and having a frangible sealing member mounted across the opening, said cap comprising:
- a means for mounting the cap to the neck of the squeeze tube;
- a chamber in the interior of the cap for enclosing the sealing member when the cap is mounted on the neck and coacting with the neck and the sealing member to prevent the sealing member from fracturing while the tube is being filled,
- the sealing member being dome shaped and the interior of the cap including a planar surface which collapses the sealing member when the cap is mounted to the neck, and the interior of the cap includes a means for forcing the sealing member into the interior of the opening of the neck while the cap is being mounted to the neck and maintaining the dome therein while the tube is being filled.
