Abstract
An ice pack including a bag having a containment section with an opening. At least one layer of adhesive material and preferably two respective layers of adhesive material may be disposed on adjacent portions of the opening. At least one removable liner and preferably two removable liners may be disposed on respective layers of the adhesive material. The ice pack may be satisfactory for a single use.
Claims22
An ice pack comprising:
- a first sidewall and a second sidewall;
- the first sidewall and the second sidewall formed with at least one layer of waterproof material;
- the first sidewall and the second sidewall bonded with each other to form a containment section and an opening in communication with the containment section;
- the opening defined in part by respective interior portions of the first sidewall and the second sidewall;
- at least one adhesive layer disposed on one interior portion of the containment section adjacent to the opening;
- and
- at least one release liner disposed on the at least one adhesive layer.
An ice pack comprising:
- a first sidewall and a second sidewall;
- the first sidewall and the second sidewall formed with at least a first layer of fluid impervious material and a second layer of soft, absorbent material;
- the first sidewall and the second sidewall adhesively bonded with each other to form a containment section and an opening in communication with the containment section;
- the opening defined in part by respective interior portions of the first sidewall and the second sidewall;
- a first adhesive layer disposed on an interior portion of the first sidewall adjacent to the opening;
- a second adhesive layer disposed on an interior portion of the second sidewall adjacent to the opening;
- a first release liner disposed on the first layer of adhesive material;
- and
- a second release liner disposed on the second layer of adhesive material.
An ice pack having a containment section and a mouth communicating with the containment section comprising:
- a first sidewall and a second sidewall;
- the first sidewall and the second sidewall formed with at least one respective layer of waterproof material;
- the first sidewall and the second sidewall bonded with each other to form the containment section and the opening to the containment section;
- the opening defined in part by respective interior portions of the first sidewall and the second sidewall;
- and
- a one time closure mechanism disposed adjacent to the mouth.
The ice pack of claim 18 wherein the one time closure mechanism further comprises:
- at least one adhesive layer disposed on one interior portion of the containment section;
- and
- at least one release liner disposed on the one at least one adhesive layer.
A method of manufacturing an ice pack comprising:
- forming a first sidewall and a second sidewall;
- bonding the first sidewall and the second sidewall with each other to form a containment section and an opening communicating with the containment section;
- placing a layer of adhesive material on an interior surface of each sidewall assembly adjacent to opening;
- and
- placing a respective release liner on each adhesive layer.
A method of using an ice pack having a mouth and a containment section comprising:
- separating a pair of release liners attached to respective adhesive layer proximate the mouth to form a generally funnel shaped configuration;
- placing ice into containment section through the funnel shaped configuration;
- removing the release liner from the respective adhesive layers;
- and
- engaging the first adhesive layer with the second adhesive layer to form a fluid barrier between the containment section and exterior portions of the ice pack.
