What is claimed is: 1. A fluid container comprising: an outer element defining an opening; an indicator for indicating a condition of a fluid in said container, said indicator being disposed in said opening, said indicator including a response assembly, an indicator head at which exhibited changes
What is claimed is: 1. A fluid container comprising: an outer element defining an opening; an indicator for indicating a condition of a fluid in said container, said indicator being disposed in said opening, said indicator including a response assembly, an indicator head at which exhibited changes are visualized and a light transmissive body connecting said response assembly and said indicator head; sealing structures established between said indicator and said outer element including a plurality of ribs integral with at least one of said indicator and said outer element; said indicator head and said indicator body being made of a first material and said outer element being made of a second material, said second material being softer than said first material; said plurality of ribs including a rib at least one of embedded in said outer element and crushed by said indicator; said sealing structure including a plurality of ribs on said indicator embedded in said outer element; and said sealing structure including annular ribs in said opening at least partly crushed by said indicator. 2. The fluid container of claim 1, said ribs being circumferential ribs on said body between said head and said response assembly. 3. The fluid container of claim 1, said outer element defining a lip and said annular ribs being disposed on said lip. 4. The fluid container of claim 3, said ribs being circumferential ribs on said body between said head and said response assembly. 5. The fluid container of claim 1, said outer element defining a radially inwardly directed lip inwardly from said opening and a bore narrower then said opening extending way from said lip, and at least one annular rib on said lip extending from said lip toward said opening. 6. The fluid container of claim 5, said head disposed against said at least one annular rib. 7. A fluid container comprising: an outer element defining an opening; an indicator for indicating a condition of a fluid in said container, said indicator being disposed in said opening, said indicator including a response assembly, an indicator head at which exhibited changes are visualized and a light transmissive body connecting said response assembly and said indicator head; sealing structures established between said indicator and said outer element including a plurality of ribs integral with at least one of said indicator and said outer element; said indicator head and said indicator body being made of a first material and said outer element being made of a second material, said second material being softer than said first material; said plurality of ribs including a rib at least one of embedded in said outer element and crushed by said indicator; and said sealing structure including circumferential ribs on said light transmissive body embedded in said outer element and annular ribs defined by said outer element at least partly crushed by said indicator. 8. The fluid container of claim 7, said outer element defining a radially inwardly directed lip inwardly from said opening and a bore narrower then said opening extending away from said lip, and at least one annular rib on said lip extending from said lip toward said opening; and said circumferential ribs on said light transmissive body being embedded in a surface defining said bore. 9. The fluid container of claim 8, said head disposed against said at least one annular rib on said lip. 10. A battery condition indicator comprising: a response assembly; a light transmissive body attached to said response assembly, said body including four wings in cruciate form; a head at an end of said light transmissive body opposite said response assembly; and at least one circumferential sealing ribs disposed on said body between said head and said response assembly, said at least one rib including an outermost sealing surface, a lead-in face adjacent said sealing surface and directed toward said response assembly, and a trailing face adjacent said sealing surface and directed toward said head, said lead-in face being sloped more gradually than said trailing face. 11. The indicator of claim 10, including a plurality of sealing plates each defining a different said sealing rib encircling said body and gussets between adjacent pairs of said wings. 12. The indicator of claim 11, said sealing plates and said wings being a monolithic body. 13. The indicator of claim 12, said head having a diameter greater than a diameter of said circumferential sealing ribs. 14. A vehicle battery comprising: a battery cover defining an opening, a lip inwardly of an outer surface of said opening, and a bore extending through said cover from said lip; at least one annular rib disposed on said lip directed toward said opening; an electrolyte conditions indicator disposed in said cover, said indicator including a head disposed against said at least one annular rib on said lip and a body extending inwardly in said battery from said head, said indicator body including at least one circumferential rib at least partly embedded in said cover within said bore; and said indicator body including a plurality of circumferential ribs embedded in said cover within said bore. 15. A vehicle battery comprising: a battery cover defining an opening, a lip inwardly of an outer surface of said opening, and a bore extending through said cover from said lip; at least one annular rib disposed on said lip directed toward said opening; an electrolyte conditions indicator disposed in said cover, said indicator including a head disposed against said at least one annular rib on said lip and a body extending inwardly in said battery from said head, said indicator body including at least one circumferential rib at least partly embedded in said cover within said bore; and including a plurality of annular ribs disposed on said lip directed toward said opening and engaged by said head. 16. The battery of claim 15, said indicator body including a plurality of circumferential ribs at least partly embedded in said cover within said bore.
