Protective head cover liner

Abstract

A protective head cover liner is comprised of a substantially oval shock-absorbing material such as rubber or the like adapted to absorb impact and sized and shaped to conform to a user's head and the inside of a head cover, such as a hat or cap. The protective head cover liner includes reliefs such as slits or the absence of material to form a concave shape approximating that of the intended user's head. The protective head cover liner may include ventilation slots and may comprise a pocket encapsulating a liquid or gel to aid in absorbing impact. The encapsulated material may be chosen to possess a high specific heat allowing the protective head cover liner to be chilled prior to use to aid in the dissipation of heat from the intended user's head over an extended period.

1 . A protective head cover liner comprising, a substantially oval shock-absorbing material sized and shaped to conform to a user's head comprising a first relief located at an approximate center of a front half of the liner, a second relief located at an approximate center of a back half of the liner, a third relief located at an approximate center of a left side of the back half of the liner, and a fourth relief located at an approximate center of a right side of the back half of the liner. 
     
     
         2 . The protective head cover liner of  claim 1 , wherein the substantially oval shock-absorbing material comprises rubber. 
     
     
         3 . The protective head cover liner of  claim 1 , wherein the first relief comprises a first slit in the substantially oval shock-absorbing material, the second relief comprises a second slit in the substantially oval shock-absorbing material, the third relief comprises a third slit in the substantially oval shock-absorbing material, and the fourth relief comprises a fourth slit in the substantially oval shock-absorbing material. 
     
     
         4 . The protective head cover liner of  claim 1 , wherein the first relief comprises a first absence of material in the substantially oval shock-absorbing material, the second relief comprises a second absence of material in the substantially oval shock-absorbing material, the third relief comprises a third absence of material in the substantially oval shock-absorbing material, and the fourth relief comprises a fourth absence of material in the substantially oval shock-absorbing material. 
     
     
         5 . The protective head cover liner of  claim 1 , wherein the substantially oval shock-absorbing material comprises a ventilation slot. 
     
     
         6 . The protective head cover liner of  claim 1 , wherein the substantially oval shock-absorbing material comprises a pocket encapsulating an additional shock-absorbing material. 
     
     
         7 . The protective head cover liner of  claim 6 , wherein the additional shock-absorbing material comprises a liquid. 
     
     
         8 . The protective head cover liner of  claim 6 , wherein the additional shock-absorbing material comprises a gel. 
     
     
         9 . The protective head cover liner of  claim 6 , wherein the additional shock-absorbing material possesses a high specific heat.
